[0031] Specifically, in one embodiment, the lock case 5 has a left-right symmetric structural design and is of a hollow structure inside. The locking bolt 7 can slide into or out of the hollow structure inside the lock case 5, enabling the locking bolt 7 to slide in or out smoothly; there is a notch on the side of the lock case 5, and the size of the side panel body of the pressing plate 1 is the same as that of the notch. After the two are fitted, they remain on the same plane, and the locking tongue 2 is located inside the lock case 5; there are four threaded holes 17 corresponding to the counterbored holes 14 of the pressing plate 1 on the end face of the lock case 5 close to the pressing plate 1. The pressing plate 1 and the lock case 5 can be firmly connected through screws.

[0032] Specifically, in one embodiment, the head of the locking bolt 7 has a wedge-shaped end face structure 19, the middle part has a stepped cylindrical structure, and the tail end is provided with an external thread 20; the middle stepped cylindrical structure of the locking bolt 7 penetrates through the through hole on the mounting panel 6.

The longitudinal spring 8 is located on the side of the mounting panel 6 away from the lock case 5; the button 9 is a cylindrical button, and there is an internal thread 21 inside the button 9 close to the locking bolt 7. The locking bolt 7 is firmly connected to the button 9 through the external thread 20 at the tail end, and the longitudinal spring 8 is located between the mounting panel 6 and the button 9. The longitudinal spring 8 is located inside the handle, and the locking bolt 7 passes through it. One end of the longitudinal spring 8 abuts against the end face of the mounting panel 6 of the handle 10, and the other end abuts against the button 9 to provide a resilience force.

[0035] Specifically, in one embodiment, the handle 10 is firmly connected to the mounting panel through screws, and there is a stepped slot hole 22 on the front face of the handle 10 for embedding and mounting the longitudinal spring 8 and the button 9.

[0036] Specifically, in one embodiment, the lock groove 11 has a left-right symmetric structural form, and a slot hole 23 is provided at the mating surface with the lock tongue 2 to achieve the locking and unlocking functions of the lock tongue 2; the lock groove 11 is installed on the lock groove fixing plate 12 through fastening screws.

[0037] The assembly method and working principle of the present utility model are as follows: During the assembly of the mechanism, first, the transverse spring 4 is inserted into the circular slot hole of the lock tongue 2, and then the larger diameter end of the pin shaft is inserted through the transverse spring 4 and into the lock tongue 2, and the smaller diameter end cylinder is inserted into the guide pin hole 13 of the pressing plate 1. At this time, the lock tongue 2 is in the ejected state; then, the lock bolt 7 is inserted through the mounting panel 6 and the lock case 5 and into the lock tongue 2; then, the longitudinal spring 8 is sleeved on the tail end of the lock bolt 7 and inserted into the stepped slot hole 22 of the handle 10; finally, the button 9 is screwed onto the lock bolt 7 through threads. When the button 9 is pressed, the lock bolt 7 moves forward under the action of the thrust, and the wedge-shaped end face structure 19 at the front end of the lock bolt 7 will exert a pressure perpendicular to the direction of the lock bolt 7 on the rectangular slot hole 15 of the lock tongue 2, forcing the lock tongue 2 to move inward towards the lock, and the lock tongue 2 will automatically fall off to reach the unlocked state; when the button 9 is released, the lock bolt will push the button 9 to move outward under the restoring force of the longitudinal spring 8, the wedge-shaped end face structure 19 at the front end of the lock bolt 7 will disengage from the lock tongue 2, and the transverse spring 4 installed in the lock tongue 2 will push the lock tongue 2 to move outward under the action of the spring restoring force, and the lock tongue 2 will automatically pop out and snap into the slot hole 23 of the lock groove 11 to reach the locked state.

[0038] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
