CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202422785213.1, filed on Nov. 15, 2024, the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The disclosure relates to the technical field of toys, and in particular, to a splicing and fitting assembly.

BACKGROUND

Children's toys usually involve assembly structures. Two structural members are respectively provided with the assembly structures, and the two structural members can be combined, and can also be separated. When combined, the two structural members are connected by the assembly structures, and when the two structural members need to be separated, a sufficient external force can be applied to make the two assembly structures disengage, so that the two structural members are separated.

A plug-in fitting structure is adopted for a common assembly structure, that is, in the two assembly structures, one is provided with an insertion slot, the other one is provided with an insertion shaft, and a combination of the two structural members can be realized by inserting the insertion shaft into the insertion slot. However, after the insertion shaft is inserted into the insertion slot, the friction therebetween is relatively large, and it is difficult for children to apply the sufficient external force to overcome the friction between the insertion shaft and the insertion slot to separate the two assembly structures. Moreover, after parts of the assembly structures are inserted and fitted, the two are further clamped and fitted by a clamping structure to reinforce the connected structure, which further increases the difficulty for separating the two structural members.

In view of the above, the disclosure is proposed.

Referring to FIGS. 1 to 3, the embodiments of the present disclosure provide a splicing and fitting assembly including: a first fitting member 1 and a second fitting member 2, where the first fitting member 1 has a concave shell 11 and a first supporting shell 12, the concave shell 11 has a groove, the first supporting shell 12 is disposed on a notch side of the concave shell 11, a first clamping part 111 is disposed on the concave shell 11, and a first guide structure 121 is disposed on the first supporting shell 12; and the second fitting member 2 has a second supporting shell 22 and a convex shell 21 projecting from the second supporting shell 22, a second clamping part 211 is disposed on a circumferential outer wall of the convex shell 21, a second guide structure 221 is disposed on the second supporting shell 22, one of the first guide structure 121 and the second guide structure 221 is provided with a first guide beveled edge, and the other one is provided with a second guide beveled edge. The splicing and fitting assembly has a spliced state and a separation state, in the spliced state, the convex shell 21 is inserted into the groove, the first clamping part 111 and the second clamping part 211 are clamped and fitted, the first guide structure 121 and the second guide structure 221 are inserted and fitted, and the first guide beveled edge and the second guide beveled edge are matched; and under an action of an external force, the first fitting member 1 and the second fitting member 2 rotate relatively, the second guide beveled edge and the first guide beveled edge slide relatively, the convex shell 21 gradually extends out of the groove, and the first clamping part 111 and the second clamping part 211 are unclamped.

The first fitting member 1 and the second fitting member 2 of the splicing and fitting assembly of the present application are connected by using a plug-in fitting structure, and in a state where the first fitting member 1 and the second fitting member 2 are connected, the two are clamped and fitted, and the connected structure is stable and difficult to be disengaged. When the first fitting member 1 and the second fitting member 2 need to be disassembled, one of the first fitting member 1 and the second fitting member 2 can be rotated, so that the second guide beveled edge and the first guide beveled edge can slide relatively, the convex shell 21 gradually extends out of the groove, and the first clamping part 111 and the second clamping part 211 are unclamped. In the present application, with respect to applying a counter-force along the convex shell 21 and an insertion direction of the groove, the first fitting member 1 and the second fitting member 2 can be easily and smoothly separated by applying a torque force, which significantly reduces the difficulty of disassembly, and is suitable for children to operate.

In some possible implementations, the first guide structure 121 includes a guide slot, the guide slot has two first guide beveled edges, and the first guide beveled edges on both sides of the guide slot gradually move closer to each other in a recessed direction of the groove; the second guide structure 221 includes an insert block, second guide beveled edges are respectively disposed on both sides of the insert block, and the two second guide beveled edges gradually move closer to each other in a protrusion direction of the convex shell 21; and in the spliced state, the insert block is inserted into the guide slot, and the two second guide beveled edges on both sides of the insert block are respectively matched with the first guide beveled edges on both sides of the guide slot.

In this implementation, the guide slot and the insert block are inserted and fitted, and the insert block can be inserted into the guide slot at the same time when the convex shell 21 is inserted into the groove. Both the insert block and the guide slot are triangular-like structures, and the insert block can slide out of the guide slot when the first fitting member 1 and the second fitting member 2 are rotate relatively.

In some possible implementations, as shown in FIG. 2, the first guide structure 121 includes a plurality of guide slots, and each of the guide slots is sequentially disposed at intervals along a circumferential direction of the groove; the second guide structure 221 includes a plurality of insert blocks, and each of the insert blocks is sequentially disposed at intervals along a circumferential direction of the convex shell 21; and in the spliced state, each of the insert block is inserted into a corresponding guide slot respectively. Through a fitting structure of the plurality of insert blocks and the plurality of guide slots, more insert blocks can share the stress and are not easily broken and damaged, thereby improving the reliability of the splicing and fitting assembly.

In some possible implementations, a spacing exists between the insert block and the convex shell 21; and a spacing exists between notches of the guide slot and the groove, so as not to interfere with the insertion and fitting between the convex shell 21 and the groove. Moreover, the circular trajectory radius where the insert block and the guide slot are located is larger, which is beneficial to providing more insert blocks and guide slots.

In some possible implementations, the two first guide beveled edges of the guide slot are connected on a recessed side of the groove to form a smoothly transitioning concave angle; and the two second guide beveled edges of the insert block are smoothly connected at an end in the protrusion direction of the convex shell 21 to form a smoothly transitioning convex angle.

The groove bottom of the guide slot and the end portion of the insert block are both smoothly transitioning structures, and the insert block has no sharp edges or corners and will not puncture the skin. Moreover, the smoothly transitioning structure is beneficial to reducing resistance and beneficial to the insert block sliding out of the guide slot.

In some possible implementations, one of the first clamping part 111 and the second clamping part 211 is a clamping protrusion, and the other one is a clamping slot; and in the spliced state, the clamping protrusion is clamped in the clamping slot. The fitting structure of the clamping protrusion and the clamping slot is beneficial to enhance the stability of the connected structure of the first fitting member 1 and the second fitting member 2.

In some possible implementations, the clamping protrusion is disposed on a circumferential inner wall of the concave shell 11, and the clamping slot is disposed on a circumferential outer wall of the convex shell 21.

Specifically, a plurality of clamping slots are disposed on a peripheral outer wall of the convex shell 21, and each of the clamping slots is sequentially disposed at intervals along the circumferential direction of the convex shell 21; a plurality of clamping protrusions are disposed on the circumferential inner wall of the concave shell 11, and each of the clamping protrusions is disposed sequentially at intervals along the circumferential direction of the concave shell 11; and in the spliced state, each of the clamping protrusions is clamped in a corresponding clamping slot respectively. The peripheral side surface of the clamping slot can smoothly transition with the peripheral outer wall of the convex shell 21. It facilitates that when rotating the first fitting member 1 or the second fitting member 2, the clamping protrusion can smoothly slide out of the clamping slot.

In some possible implementations, the clamping slot extends along the protrusion direction of the convex shell 21; and the concave shell 11 is provided with a hollow part 112, the clamping protrusion extend into the hollow part 112, the clamping protrusion may be a shrapnel, the shrapnel extends to the hollow part 112 with relatively good elasticity, and the shrapnel extends to an inner side of the groove to be conveniently inserted into the clamping slot.
