Referring to FIG. 1 and FIG. 2, the present disclosure provides a bed fitting device 100, which comprises a first assembly 10 and a second assembly 20. The first assembly 10 comprises a first bracket 11 and a first locking part 12, wherein the first bracket 11 is configured to be disposed on a first splicing plate 201 at the outer side, the first bracket 11 is provided with a first insertion slot 111, and the first locking part 12 is movably arranged on the first bracket 11 and has a locking position M1 (as shown in FIG. 5) and an unlocking position M2 (as shown in FIG. 4) relative to the first bracket 11. The second assembly 20 comprises a second bracket 21 and a second locking part 22, wherein the second bracket 21 is configured to be disposed on a second splicing plate 202 at the outer side, and the second locking part 22 is arranged on the second bracket 21. When the second locking part 22 is inserted into the first insertion slot 111 and the first locking part 12 is located at the locking position M1, the first locking part 12 locks the second locking part 22 in the first insertion slot 111. When the first locking part 12 is located at the unlocking position M2, the second locking part 22 can exit the first insertion slot 111. In the present disclosure, by providing the first locking part 12 in the first assembly 10, the second locking part 22 can be quickly locked when the second locking part 22 is inserted into the first insertion slot 111, so that the external first splicing plate 201 and the second splicing plate 202 can be installed and fixed quickly, thereby effectively improving the efficiency of assembly. When the external first splicing plate 201 and second splicing plate 202 need to be disassembled, the first locking part 12 is adjusted to unlock the second locking part 22, so that the external first splicing plate 201 and second splicing plate 202 can be separated relatively, thereby improving the efficiency of disassembly.

In some embodiments, referring to FIG. 3 and FIG. 4, the second locking part 22 is inserted into and connected with the first insertion slot 111 in the first direction X. The first locking part 12 comprises a cam 121 and a sliding block 122, and the cam 121 is rotatably arranged on the first bracket 11. The sliding block 122 is arranged on the first bracket 11 in a reciprocating manner along the second direction Y, and the sliding block 122 is connected with the cam 121, wherein the first direction X and the second direction Y are perpendicular to each other. The radius of at least one part of the cam 121 is different from that of another part, so that when the cam 121 rotates, it can drive the sliding block 122 to switch between the locking position M1 and the unlocking position M2. Specifically, referring to FIG. 5 together, when the second locking part 22 is inserted into the first insertion slot 111, the cam 121 rotates to drive the sliding block 122 to move to the locking position M1, and the sliding block 122 abuts against the second locking part 22 to restrict the second locking part 22 from exiting the first insertion slot 111 in the direction opposite to the first direction X, so that the sliding block 122 locks the second locking part 22 in the first insertion slot 111.

In some embodiments, referring to FIG. 3 and FIG. 6, the second locking part 22 comprises a first clamping piece 221, and one end of the first clamping piece 221 is connected with the second bracket 21. The first clamping piece 221 is partially bent and extends along the first direction X. In the third direction Z, the first clamping piece 221 is partially spaced from the second bracket 21 to form a gap. When the first clamping piece 221 is inserted into the first insertion slot 111, a part of the first bracket 11 is located in the gap, i.e., the part of the first bracket 11 respectively abuts against and connects with the second bracket 21 and the first clamping piece 221. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

Referring to FIG. 4 and FIG. 5, an end of the sliding block 122 that is near the first insertion slot 111 is provided with a first clamping tooth 1221, and the first clamping piece 221 is provided with a second clamping tooth 2211 at a first side wall 221a towards the sliding block 122. When the first clamping piece 221 is located in the first insertion slot 111 and the sliding block 122 is located at the locking position M1, the first locking tooth 1221 is engaged with the second locking tooth 2211 so that the first clamping piece 221 is locked in the first direction X. Since the first bracket 11 is located between the first clamping piece 221 and the second bracket 21, the first clamping piece 221 is locked in the third direction Z.

In some embodiments, referring to FIG. 3 and FIG. 4, the first bracket 11 is provided with an opening 114 and a second insertion slot 115, the second locking part 22 further comprises a second clamping piece 222, and the second clamping piece 222 can be inserted into and connected with the second insertion slot 115 through the opening 114. By arranging both the first clamping piece 221 and the second clamping piece 222 on the second bracket 21 to be inserted into and connected with the first bracket 11 at the same time, the second clamping piece 222 can share part of the force to reduce the stress of the first clamping piece 221, so as to avoid the deformation and failure of the first clamping piece 221 caused by the concentration of all the stress on the first clamping piece 221.

In some embodiments, referring to FIG. 4 and FIG. 5, the first clamping tooth 1221 on the sliding block 122 is obliquely arranged towards the first direction X, i.e., the first clamping tooth 1221 is inclined downward. The second clamping tooth 2211 on the first clamping piece 221 is obliquely arranged in the opposite direction of the first direction X, i.e., the second clamping tooth 2211 is inclined upwards, wherein the first direction X is the direction in which the first clamping piece 221 enters the first insertion slot 111, and the opposite direction of the first direction X is the direction in which the first clamping piece 221 exits the first insertion slot 111. By arranging the first clamping tooth 1221 and the second clamping tooth 2211 in the above structures, it is difficult for the first clamping tooth 1221 to be detached from the second clamping tooth 2211 when the sliding block 122 is located at the locking position M1 and the first clamping piece 221 is locked in the first insertion slot 111, thereby improving the locking effect of the sliding block 122 on the first clamping piece 221.

In some embodiments, referring to FIG. 3 and FIG. 4, the first bracket 11 is further provided with a guiding protrusion 112, which defines part of the boundary of the first insertion slot 111. In the first direction X, the guiding protrusion 112 is gradually inclined towards the sliding block 122. The guiding protrusion 112 is configured to abut against a second side wall 221b of the first clamping piece 221 facing away from the sliding block 122. The guiding protrusion 112 is arranged in a structure inclined towards the sliding block 122, so that the first clamping piece 221 can be guided into the first insertion slot 111 to move in a direction approaching the sliding block 122. Moreover, when the sliding block 122 locks the first clamping piece 221, the first clamping tooth 1221 and the guiding protrusion 112 respectively abut against both sides of the first clamping piece 221 in the second direction Y, thereby locking the first clamping piece 221 in the second direction Y. At the same time, the guiding protrusion 112 also helps to prevent the second clamping tooth 2211 from being detached from the first clamping tooth 1221.

In some embodiments, referring to FIG. 3 to FIG. 5, the first locking part 12 further comprises an elastic member 123 which is respectively connected with the first bracket 11 and the sliding block 122, and the clastic member 123 is used for driving the sliding block 122 to move from the unlocking position M2 to the locking position M1. As some examples, the elastic member 123 is arranged on one side of the sliding block 122 facing away from the first insertion slot 111, and the elastic member 123 is in a compressed state. When the cam 121 rotates so that the sliding block can move from the unlocking position M2 to the locking position M1, the sliding block is driven to move to the locking position M1 under the elastic force of the elastic member 123. When the cam 121 rotates to push the sliding block 122 to move from the locking position M1 to the unlocking position M2, the elastic member 123 is compressed. As an example, the elastic member 123 may be a spring. By arranging the clastic member 123 respectively connected with the first bracket 11 and the sliding block 122, on the one hand, the sliding block 122 can be enabled to quickly move from the unlocking position M2 to the locking position M1 so that the first clamping piece 221 can be locked quickly; and on the other hand, when the cam 121 is no longer rotating, the elastic member 123 can keep the sliding block 122 in the locking position M1 so as to maintain the locking effect of the sliding block 122 on the first clamping piece 221.

In some embodiments, the sliding block 122 is provided with an installation cavity 1222, and the elastic piece 123 is partially arranged in the installation cavity 1222 and partially abuts against the wall of the installation cavity 1222. By arranging the installation cavity 1222 on the sliding block 122 to accommodate the elastic member 123, the elastic member 123 can be enabled to extend and retract in the second direction Y as much as possible, thereby driving the sliding block 122 to move smoothly in the second direction Y.

In some embodiments, referring to FIG. 3 and FIG. 6, the first assembly 10 further comprises a housing 13, wherein the housing 13 is connected with the first bracket 11 to enclose an accommodating cavity 131, and the first locking part 12 is arranged in the accommodating cavity 13. With the above structure, the housing 13 can protect the first locking part 12 and prevent the first locking part 12 from being directly exposed to the outside, thereby preventing foreign matters from adhering to the first locking part 12 and thus affecting the normal operation of the first locking part 12. The first bracket 11 has a supporting part 113, and the first locking part 12 further comprises a transmission rod 124 and a knob 125, wherein the transmission rod 124 is rotatably connected to the supporting part 113, one end of the transmission rod 124 is connected with the cam 121, the opposite end of the transmission rod 124 extends out of the housing 13 to be connected with the knob 125, and the knob 125 is located at the outer side of the housing 13 to be operated by the user conveniently. Under the connection of the transmission rod 124, the cam 121 inside the accommodating cavity 131 and the knob 125 outside the accommodating cavity 131 can rotate synchronously, so that the user can operate outside the accommodating cavity 131 to drive the cam 121 to rotate.

In some embodiments, referring to FIG. 4, the first assembly 10 further comprises a first limiting part 14 that is connected with the first locking part 12, and the first limiting part 14 is used for limiting the rotation of the first locking part 12 so that the first locking part 12 is switched between the locking position M1 and the unlocking position M2. As an example, the first limiting part 14 comprises a limiting plate, which is arranged on the transmission rod 124 and rotates synchronously with the transmission rod 124. The limit plate has an abutting position with the first bracket 11. When the transmission rod 124 rotates to the extent that the limit plate abuts against the first bracket 11, the transmission rod 124 cannot continue to rotate, but can only rotate in the opposite direction. This can limit the rotation of the cam 121, thereby limiting the switching of the sliding block 122 between the locking position M1 and the unlocking position M2. In some other embodiments, the first limiting part 14 comprises a first protrusion, a second protrusion and a limiting bar, wherein the first protrusion and the second protrusion are arranged on the first bracket 11 or the housing 13, and the limiting bar is arranged on the transmission rod 124 and moves between the first protrusion and the second protrusion. When the limiting bar abuts against the first protrusion, the sliding block 122 is in the unlocking position M2; and when the limiting bar abuts against the second protrusion, the sliding block 122 is in the locking position M1.

In some embodiments, referring to FIG. 6, the first assembly 10 further comprises a second limiting part 15 that is connected with the first locking part 12, and the second limiting part 15 is used for limiting the movement of the cam 121 along the third direction Z so as to keep the cam 121 connected with the sliding block 122 and prevent the cam 121 from being disconnected from the sliding block 122. As an example, the second limiting part 15 comprises a stopper which is arranged on the transmission rod 124 and abuts against the supporting part 113, thereby limiting the movement of the transmission rod 124 in the third direction Z and preventing the cam 121 from moving in the third direction Z and thus being separated from the sliding block 122.

Referring to FIG. 1, the present disclosure provides an embodiment of a bedstead 200, wherein the bedstead 200 comprises a bed fitting device 100, a first splicing plate 201 and a second splicing plate 202. The first assembly 10 in the bed fitting device 100 is fixedly arranged on the first splicing plate 201, and the second assembly 20 in the bed fitting device 100 is fixedly arranged on the second splicing plate 202. The first splicing plate 201 is vertically spliced with the second splicing plate 202. When the first splicing plate 201 and the second splicing plate 202 need to be assembled, the first clamping piece 221 in the second assembly 20 is directly inserted into and connected with the first insertion slot 111 of the first assembly 10, and then the first locking part 12 is rotated to the locking position M1. Simply by this operation, the second assembly 20 can be locked by the first assembly 10, so that the first splicing plate 201 and the second splicing plate 202 are locked. Thus, as compared to tightening the bolts for securing, the assembly efficiency of the present disclosure is obviously improved. When the first splicing plate 201 and the second splicing plate 202 need to be disassembled, the first locking part 12 is rotated to the unlocking position M2, so that the first assembly 10 unlocks the second assembly 20. By pulling the first clamping piece 221 in the second assembly 20 from the first insertion slot 111 of the first assembly 10, the first splicing plate 201 and the second splicing plate 202 are detached from each other, so that the disassembly efficiency is also significantly improved.

The bed fitting device 100 of the present disclosure comprise a first assembly 10 and a second assembly 20. The first assembly 10 comprises a first bracket 11 and a first locking part 12, wherein the first bracket 11 is configured to be disposed on a first splicing plate 201 at the outer side, the first bracket 11 is provided with a first insertion slot 111, and the first locking part 12 is movably arranged on the first bracket 11 and has a locking position M1 and an unlocking position M2 relative to the first bracket 11. The second assembly 20 comprises a second bracket 21 and a second locking part 22. The second bracket 21 is configured to be disposed on a second splicing plate 202 at the outer side, and the second locking part 22 is arranged on the second bracket 21. The second locking part 22 is configured to be inserted into and connected with the first insertion slot 111, and the first locking part 12 locks the second locking part 22 when the first locking part 12 is in the locking position M1, and unlocks the second locking part 22 when it is in the unlocking position M2. Through the above structure, the bed fitting device 100 of the present disclosure can realize the rapid assembly and locking as well as rapid disassembly and separation of the bedstead 200, thereby effectively improving the installation and disassembly efficiency.

What described above are only the embodiments of the present disclosure, but are not intended to limit the scope of the present disclosure. Any equivalent structures or equivalent process flow modifications that are made according to the specification and the attached drawings of the present disclosure, or any direct or indirect applications of the present disclosure in other related technical fields shall all be covered within the scope of the present disclosure.
