Detailed Description
As shown in fig. 1-3, a door lock convenient for back locking includes a door lock mounting plate 1, a door handle 2 connected to the door lock mounting plate 1, a lock cylinder element 3 connected to the door handle 2, a latch bolt 4 connected to the lock cylinder element 3, and a stop baffle 5 connected to the door lock mounting plate 1, wherein a stop block 6 is arranged on the lock cylinder element 3, a sliding groove 7 and a sliding block 8 slidably connected to the sliding groove 7 are arranged on the door handle 2, a limit groove 9 is respectively arranged on the door lock mounting plate 1 and the lock cylinder element 3, the limit groove 9 penetrates through the door lock mounting plate 1 and the lock cylinder element 3, and the position of the limit groove 9 corresponds to the position of the sliding groove 7.
When the door lock needs to be locked reversely, firstly, the door handle 2 needs to be in an initial state, then a user pushes the sliding block 8 to slide towards the direction of the lock cylinder element 3 so that the sliding block 8 enters the limiting groove 9, because the door lock mounting plate 1 and the lock cylinder element 3 are respectively provided with the limiting grooves 9, and the position of the door lock mounting plate 1 is fixed, therefore, when the sliding block 8 enters the limiting groove 9, the door handle 2 cannot rotate, the door lock is locked reversely, compared with the traditional door lock structure, the door lock can be quickly locked reversely, the reverse locking structure of the door lock is simplified, and meanwhile, the manufacturing cost of the door lock is greatly reduced.
The sliding block 8 is provided with a poking plate 10, and the top of the poking plate 10 is higher than the upper surface of the sliding groove 7.
Because the sliding block 8 is provided with the toggle plate 10, and the top of the toggle plate 10 is higher than the upper surface of the sliding groove 7, the user can push the sliding block 8 conveniently, and the user can lock the door lock reversely or unlock the door lock conveniently.
