Their swinging parts 30 and the inclined part 22 of the button 2 abut against each other. Pressing the button 2 causes the two latches 3 to open synchronously, thus unlocking the door. The button 2 directly pushes the latches 3, simplifying unnecessary transmission parts and making assembly easier. After pressing the button 2 to unlock, users can push and pull the movable door by holding the lock body 1, which is convenient and has a longer service life. Closing the movable door causes the insert 51 inside the frame to engage with the latches 3. As the movable door closes, the insert 51 pushes open the two latches 3, and the two latches 3 hook the insert 51 to lock the door. The locking action is similar to existing structures. Pressing the button 2 moves the button 2, and the inclined part 22 pushes the two swinging parts 30 together, causing the two latches 3 to open and allowing the insert 51 to disengage, thus unlocking the door. Simultaneously, users can push and pull the movable door by holding the lock body 1.
[0022] In this embodiment, the mounting plate 4 has an opening 400 on the side away from the lock body 1 for the insert 51 to enter and exit. The opening 400 corresponds to the space between the two latches 3. The insert 51 and the opening 400 belong to the structure of existing bolt locks or self-closing locks. The existing structure also includes a lock seat installed in the frame. The insert 51 is installed on the lock seat and corresponds to the opening 400, and the insert 51 is arrow-shaped.

Figure 3 The cover plate 5 can also be omitted, and the clip 3 can be held in place by screws and mounting plate 4, ensuring that the clip 3 can swing normally while preventing it from detaching. Based on this, the button 2 has a mounting groove 205 on the side near the mounting plate 4, and the mounting groove 205 is located on both sides of the slot 20, as shown in the reference. Figure 4A slot 20 is located in the middle of one side of the button 2. Two mounting slots 205 are provided on both sides of the slot 20. A spring 200 corresponding to the mounting slot 205 is provided at the bottom of the button 2. The button 2 has a hollow structure with a certain space at the bottom. An insert 51 is provided on one edge of the cover plate 5. The insert 51 is inserted into the mounting slot 205 and can slide in the mounting slot 205 along the width direction of the lock body 1.

Regarding the locking body 1, it should be noted that the width of the mounting groove 205 is greater than the thickness of the insert 51. Under normal conditions, the insert 51 is placed inside the mounting groove 205 and abuts against the groove wall located below the mounting groove 205. At this time, the insert 51 is a certain distance away from the groove wall located above the mounting groove 205 to prevent the insert 51 from blocking the button 2 when it is pressed. When the button 2 is pressed, the mounting groove 205 gradually moves downward until the insert 51 abuts against the groove wall located above the mounting groove 205. Due to the presence of the insert 51, the button 2 cannot move further down. This is the maximum stroke.
[0023] In this embodiment, springs 200 are provided on both sides of the bottom of the button 2. The end of the spring 200 away from the button 2 abuts against the lock body 1.
