When closing the door, pull the moving door so that the moving door is close to the static door and then lock the moving door, but when the moving door is pulled hard, there will be a certain rebound after the faster moving moving door hits the static door, making the moving door It is not close to the static door. When the user locks the movable door without noticing this problem, the lock hook on the movable door does not engage with the lock groove on the static door, resulting in a false lock phenomenon, which is extremely Greatly reduces the safety performance of the mobile door, and the anti-theft effect is not good

The invention discloses a false-locking prevention door lock structure comprising a housing. A lock tongue, and a push plate provided with a stirring block and capable of sliding leftward and rightward are disposed inside the housing. A clamp pole is arranged on the bottom end surface of the stirring block, and is located at the clamping position of the push plate. A movable door strip having a U-shaped structure is fixedly connected to the front end of the housing. A connecting rod located in a U-shaped groove of the movable door strip is mounted on the front end surface of the push plate. The connecting rod is provided with a lock slot matching the lock tongue. A lock hook is arranged on the front end surface of the connecting rod. The movable door strip is provided with a strip groove used for making room for the lock hook. A safety block capable of sliding back and forth is amounted in the housing. A circle portion and a square portion are sequentially arranged on the front end surface of the safety block from back to front. The connecting rod is provided with a sliding groove matching the square portion. The sliding groove is provided with a through hole which the circle portion of the safety block can penetrate, so that the square portion can extend from the front end of the movable door strip. The door lock structure is simple and compact, can effectively prevent false-locking phenomena, and has good antitheft effects.
Description
technical field [0001] The invention relates to a door lock structure, in particular to an anti-fake lock structure applied to a movable door. Background technique [0002] In daily life, the portable door with small footprint is more and more popular among people. When opening the door, the whole door can be moved into the wall with reserved space, which is beautiful and generous, and saves space; With the crowded living space, it is becoming more and more popular to use sliding doors instead of sliding doors that take up a lot of space. Especially for large warehouses, the use of moving doors can obviously save the space occupied by the doors. The switch is also easier and simpler than the sliding door in the traditional technology. When closing the door, pull the moving door so that the moving door is close to the static door and then lock the moving door, but when the moving door is pulled hard, there will be a certain rebound after the faster moving moving door hits t...
