Each of the first lock body 11 and the second lock body 12 is provided with a mounting seat 14, which is detachably connected to the door, a cylinder plug seat 15, which is movably connected to the first lock body 11 and the second lock body 12, a cylinder plug 16, which is connected to the cylinder plug seat 15, a transmission rod 17, one end of which is connected to the cylinder plug 16 and the other end of which is connected to the linkage 13, and a spring 18, which is sheathed at the transmission rod 17 to allow the movement of the cylinder plug seat 15. A first lock body 11 and a second lock body 12 are provided, so as to implement different unlocking and door opening methods on two sides of a door, i.e., unlocking by means of pressing on a side and unlocking by means of pulling-out on the other side, thereby greatly improving the usage convenience; moreover, the unlocked door can be directly opened by means of a pulling-out force or a pressing force, such that the unlocking and door opening are realized using the same force, and the operation is simple. A linkage 13 is provided, with one end of the linkage 13 being connected to the first lock body 11, and the other end thereof being connected to the second lock body 12, so as to construct a bridge between the lock bodies on the two sides of the door. When the lock is unlocked by means of pressing on the side where the first lock body 11 is mounted or the lock is unlocked by means of pulling-out on the side where the second lock body 12 is mounted, the linkage 13 can accurately transfer an actuation force between the lock bodies on the two sides in a timely manner, such that the first lock body 11 and the second lock body 12 operate synchronously, thereby implementing the function of unlocking and opening the door on both sides of the door. This double-sided linkage design overcomes the single-sided operation limitation of traditional door locks, thereby meeting requirements for convenient access from both sides of the door in different scenarios, and greatly improving the usage convenience for a user. Moreover, a transmission structure of a double-sided lock body 1 is also simplified, so as to facilitate the mounting of a door lock, reduce the complexity and cost of the structure, and facilitate maintenance, thereby improving the economy and applicability of a product. A mounting seat 14 is provided, so as to facilitate the connection of the first lock body 11 and the second lock body 12 to the door. It is possible to first connect the mounting seat 14 to the door, and it is also possible to first connect the mounting seat 14 to the first lock body 11 or the second lock body 12 and then to the door.

In an embodiment, the first lock body 11 further includes a first case 111, which is connected to the mounting seat 14, a sliding slot 112, which is provided on the first case 111, a fixed slider 113, which passes through the transmission rod 17 to be connected to the cylinder plug seat 15 and is also slidably connected to the sliding slot 112, and a cover plate 114, one end of which is connected to the first case 111 and the other end of which is connected to the spring 18 to allow the transmission rod 17 to pass through. A mounting column 1111 for fixing the cover plate 114 is arranged on the first case 111. An end of the spring 18 is connected to the fixed slider 113 and sheathed on the transmission 17 on the fixed slider 113, and the other end thereof is connected to the cover plate 114. When pressure is applied to the cylinder plug seat 15 on the first lock body 11, the cylinder plug seat 15, together with the cylinder plug 16 and the fixed slider 113, pushes the transmission rod 17 to move along the sliding slot 112, the fixed slider 113 squeezes the spring 18 towards the direction of the cover plate 114, and the transmission rod 17 drives the linkage 13 to move towards the direction of the second lock body 12.

In an embodiment, the second lock body 12 includes a second case 121, which is connected to the mounting seat 14, a retaining slot 1211, which is provided on the second case 121, a strike 122, which is connected to the retaining slot 1211, a driving plate 123, which is mounted within the second case 121, passes through the transmission rod 17 to be connected to the cylinder plug seat 15, and can drive the movement of the strike 122 by means of compressing the spring 18, a baffle plate 124, which is arranged on the second case 121, can pass through the cylinder plug 16 to be connected to the spring 18 at an end, and is connected to the cylinder plug seat 16 at the other end, a circlip 125, which is connected to the transmission rod 17 and located above the driving plate 123, and a limiting ring 126, which is connected to the transmission rod 17 and located below the driving plate 123 for limiting the rotation of a latch hook 1223. A limiting slot 1261 for limiting the rotation of the latch hook 1223 is provided on the limiting ring 126 in a circumferential direction. The strike 122 includes a notched block 1221, which fits the retaining slot 1211, a rotation shaft 1222, which is arranged on the notched block 1221, and a latch hook 1223, which is arranged on the rotation shaft 1222. A limiting rod 1224 is arranged at an end of the latch hook 1223. An end of the spring 18 is connected to the baffle plate 124 and sheathed on the cylinder plug 16, and the other end thereof is sheathed outside the transmission rod 17 and connected to the limiting ring 126. When a key is used to rotate the cylinder plug 16 on the second lock body 12, such that the cylinder plug 16 on the second lock body 12 drives the transmission rod 17 on the second lock body 12 to rotate, or when a key is used to rotate the cylinder plug 16 on the first lock body 11, the cylinder plug 16 on the first lock body 11 drives the transmission rod 17 on the first lock body 11 and the linkage 13 to rotate, the linkage 13 drives the transmission rod 17 on the second lock body 12 to rotate, and the transmission rod 17 drives the limiting ring 126 to rotate. When the limiting slot 1261 on the limiting ring 126 is separated from the limiting rod 1224 on the latch hook 1223, the cylinder plug seat 15 is pulled out, the cylinder plug seat 15, together with the cylinder plug 16 and the driving plate 123 connected to the cylinder plug seat 15, moves outwards, and the driving plate 123 drives the transmission rod 17 and the limiting ring 126 to squeeze the spring 18. When moving outwards, the driving plate 123 presses the latch hook 1223 downwards, such that the latch hook 1223 is rotated around the rotation shaft 1222 on the notched block 1221. When the driving plate 123 presses to the lowest position, the latch hook 1223 is rotated into the second lock body 12, so as to unlock, and at the same time, the unlocked door can be directly pulled open by means of the pulling-out force. When a key is used to rotate the cylinder plug 16 on the first lock body 11 or the second lock body 12, the cylinder plug 16 drives the transmission rod 17 to rotate, and the transmission rod 17 drives the limiting ring 126 to rotate, such that the limiting rod 1224 on the latch hook 1223 is rotated into the limiting slot 1261 on the limiting ring 126. Afterwards, when the first lock body 11 is pressed or the second lock body 12 is pulled out, the driving plate 123 and the limiting ring 126 press the latch hook 1223 downwards, enabling the latch hook 1223, together with the notched block 1221, to slide to the bottom of the retaining slot 1211 along the retaining slot 1211, such that the latch hook 1223 cannot be rotated to unlock. The circlip 125 is provided for fixing a mounting position of the transmission rod 17, which is fixed to the driving plate 123. The driving plate 123 is provided, which can pass through the transmission rod 17 to be connected to the cylinder plug seat 15, and can accurately receive the actuation force transferred from the cylinder plug seat 15 during unlocking. Either pressing the cylinder plug seat 15 on the side of the first lock body 11 or pulling out the cylinder plug seat 15 on the side of the second lock body 12, the driving plate 123 can efficiently and stably transfer the actuation force to the latch hook 1223, so as to push the latch hook 1223 to move, thereby implementing the function of unlocking from both sides of the door. Moreover, this efficient actuation force transfer mechanism ensures the smooth linkage of the double-sided lock body 1, enabling a user to easily unlock the door from any side of the door, and thus greatly improving the usage convenience for the user. The limiting slot 1261 is provided on a limiting ring 126, and the limiting rod 1224 is provided on the latch hook 1223, such that after the cylinder plug 16 is rotated to drive the rotation of the transmission rod 17 and the limiting ring 1261 and the limiting rod 1224 enters the limiting slot 1261, the lock bodies cannot be unlocked by means of pulling-out or pressing, thereby improving the safety of the lock bodies.

In an embodiment, an end of the transmission rod 17 is provided with a first slot 171, which fits the cylinder plug 16, and the other end thereof is provided with a second slot 172, which fits the linkage 13. The first slot 171 fits a transmission component on the cylinder plug 16. When the cylinder plug 16 is rotated, the transmission rod 17 is rotated along with same, and drives the linkage 13 to rotate. The second slot 172 needs to fit the transmission rod 17 to precisely transfer a force, so as to realize unlocking.
