As shown in fig. 1 and 2, the present invention provides a damage prevention structure for preventing rigid impact from damaging a door lock structure when a push-pull door lock is unlocked, which comprises a transmission base 1, a transmission member 2 slidably connected to the transmission base 1, an elastic member 3 respectively connected to the transmission base 1 and the transmission member 2, and a rotation member 5 connected to the transmission member 2; the transmission base 1 moves to drive the transmission part 2 to move, the transmission part 2 drives the rotating part 5 to rotate to unlock position, the transmission base 1 continues to move, and the elastic part 3 is compressed to apply elastic force to the transmission part 2. Through transmission base 1, elastic component 3 and driving medium 2 constitute an elastic buffering loss prevention structure, accomplish the action of unblanking and stall when rotating piece 5, driving medium 2 also the stop motion, can drive transmission base 1 when 8 application of force of door handle open the door and continue to remove, transmission base 1 compression elastic component 3, the excessive power of unblanking of exerting when elastic component 3 absorbs the door that opens the door, avoid causing the impact damage to the structure of lock, the structure in the lock has been protected, the life of lock has been prolonged, and simple structure, the installation of being convenient for is maintained.

In this embodiment, the transmission base 1 is provided with a sliding groove 11 for the transmission member 2 to slide. The rotating part 5 is a gear, the transmission part 2 is provided with a rack 21, and the rotating part 5 is in meshing transmission with the transmission part 2. The engagement transmission is adopted for the embodiment, but in practical application, the rotating member 5 may also adopt a lever structure, and a push-pull rod is arranged on the transmission member 2 to push the rotating member 5 to indirectly act on the lock body, so as to realize unlocking. Besides, the connection relationship between the rotating piece 5 and the transmission piece 2 can be provided with a transmission structure according to the specific structure of a common lock.

Specifically, the transmission member 2 is provided with a through hole 22 for placing the elastic member 3. The transmission base 1 is provided with a groove 12 for placing the elastic element 3. The elastic element 3 is a spring or a spring plate, and besides, the elastic element 3 can also be other parts which can reset after being compressed and eliminate impact force. The size of the through hole 22 is matched with the size of the spring or the elastic movement range of the elastic sheet. The transmission base 1 is provided with a blocking piece 13 for limiting the moving direction of the transmission base. When the transmission base 1 is connected with the panel 7, the clamping piece is in sliding connection with the sliding groove on the panel so as to limit the transmission base to move on the panel only along the direction of the sliding groove. The detent 13 may be a dovetail block. The transmission base 1 is also provided with a driving hole, the driving hole is connected with a rotating shaft, and the rotating shaft is connected with a door handle 8. The door handle 8 is pushed, and the rotating shaft acts on the driving hole to drive the transmission base 1 to move.
