A limiting structure 44 is disposed between the push-pull rod 42 and the driving sliding groove 41, and the limiting structure 44 includes a positioning step 442 disposed in the driving sliding groove 41 and a positioning shoulder 441 disposed on the push-pull rod 42. The push-pull rod 42 is prevented from being separated from the driving slide groove 41 when moving by the limit structure 44. When the external force application push-pull rod 42 moves along the driving sliding groove 41, the driving block 43 is forced to press down the elastic buckle block 31 to move along the guiding sliding groove 211 towards the end far away from the driving assembly 40, one end of the limiting rib 32 protruding out of the abdicating notch 212 is separated from the mounting hole 11 and is clamped into the abdicating groove 231.
Example two
Referring to fig. 6, the specific structure and operation principle of the present embodiment are substantially the same as those of the first embodiment, and therefore are not described herein again, but the following points are different: the elastic structure 33 comprises a guide notch arranged at one end of the elastic buckling block 31 close to the bottom of the guide sliding groove 211 and a spring arranged in the guide notch, wherein one end of the spring is connected to the bottom of the guide sliding groove 211, the other end of the spring is abutted to the inner wall of the guide notch, and the elastic buckling block 31 is forced to abut to the driving component 40.
The door lock assembly 20 disassembly step is described below according to the structure of the first embodiment:
1. an initial state. The joint portion 22 passes through the mounting hole 11 just base 21 and spacing convex shoulder 23 butt respectively are in the both sides of installation panel 10, the joint portion 22 does not set up the both sides outer wall of spacing convex shoulder 23 butt respectively on first assembly limit 12, joint portion 22 is equipped with spacing convex shoulder 23 and keeps away from one side outer wall butt of bullet knot piece 31 at one of them second assembly limit 13, elasticity support arm 331 butt forces the one end butt of bullet knot piece on push-and-pull rod 40 on spacing step 332 to make restriction muscle 32 salient in the one end card of abdicating breach 212 go into the mounting hole 11 and butt on another second assembly limit 13.
2. The latch assembly 30 is released from its position. The grabbing push-pull rod 42 moves along the driving sliding groove 41 and towards the direction of one side of the push-pull handle 421 to drive the driving block 43 to abut against and apply force on the elastic buckle block 31, so that the elastic support arm 331 abuts against the limiting step 332 to be elastically deformed, the elastic buckle block 31 moves towards one side of the clamping portion 22 along the guiding sliding groove 211 until the limiting rib 32 protrudes out of one end of the abdicating notch 212 to be separated from the mounting hole 11 and embedded into the abdicating groove 231, and a gap exists between the outer wall of one side of the clamping portion 22 close to the elastic buckle block 31 and the second assembling edge 13.
3. The door lock assembly 20 is removed. The clamping portion 22 is moved transversely, the outer wall of one side, close to the elastic buckling block 31, of the clamping portion 22 abuts against the second assembling edge 13, and therefore sufficient space is reserved between the outer wall of one side, far away from the elastic buckling block 31, of the clamping portion 22 and the second assembling edge 13, so that the limiting convex shoulder 23 on one side of the clamping portion penetrates through the mounting hole 11 and is separated from the mounting door panel 10.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
