Problems solved by technology

[0004] Therefore, in order to improve the strength of the whole door, the strength of the door lock must be raised to a level compatible with the strength of the door panel. However, the actual door lock structure often fails to meet such requirements.

Abstract

The invention relates to a pickproof door lock structure comprising a door leaf, a lock body and a lock cylinder. The pickproof door lock structure further comprises a reinforcing plate and a lock protector. The door leaf comprises an outer face plate and an inner face plate. The reinforcing plate is fixedly installed on the inner side of the outer face plate. A support hole is formed in the reinforcing plate. The lock protector is installed in the door leaf and comprises a lock sleeve part and a mounting part. The lock sleeve part penetrates through the support hole and the mounting hole andextends out from the surface of the outer face plate. The mounting part is fixedly connected with the reinforcing plate. The lock sleeve part is provided with an inner cavity. The lock cylinder is contained in the inner cavity. According to the pickproof door lock structure, the strength of a door lock is high, and pickproof performance is good.

Description

technical field [0001] The invention relates to a door lock structure, in particular to an anti-prying door lock structure. Background technique [0002] Doors are an essential part of a building, and are mainly used to isolate the interior of a building from the outside or the interior space of a building. As an important part of the door, the door lock is an important barrier for building safety. [0003] With the innovation of technology and the continuous development of technology, the strength of armored door panels on the market is getting higher and higher, and the performance of anti-tampering is getting better and better. However, what is inconsistent with it is that the strength of the door lock, as the core component of the whole door, has not been improved accordingly. According to the "barrel law", how much water a bucket can hold depends on the shortest piece of wood. For a door, its strength will ultimately be determined by the weaker one of the door panel o...
