Description

Anti-picking lock tongue reinforcing structure of intelligent door lock Technical Field The utility model relates to the technical field of intelligent door locks, in particular to an anti-prying lock tongue reinforcing structure of an intelligent door lock. Background With the progress of scientific technology, the demand for intelligence is increasing, and a plurality of series of intelligent home products are derived to assist people to live more conveniently. The intelligent door lock is an improved lock which is different from the traditional mechanical lock and is more intelligent and simplified in the aspects of user safety, identification and manageability. The intelligent door lock is an executive component for locking the door in an access control system. The intelligent door lock is taken as an important component of modern household safety, not only provides a convenient use mode, such as fingerprint unlocking, face unlocking and the like, but also brings high-end intelligent experience and a heart-pasting security function, such as a visual doorbell, a door lock alarm and the like. In the prior art, if an illegal person is used for picking the lock, a card or an iron wire can be used for being embedded into a door slot, and an attempt is made to push a lock tongue through extruding an arc-shaped surface, so that the door lock is pried open, and the safety performance is poor, therefore, the anti-picking lock tongue reinforcing structure of the intelligent door lock is provided. Disclosure of utility model The utility model aims to provide an anti-prying lock tongue reinforcing structure of an intelligent door lock, which can prevent illegal personnel from prying the lock tongue by using a card or an iron wire, improves the safety performance and solves the problems in the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides an anti-pick lock tongue reinforced structure of intelligent door lock, includes intelligent door lock body, the lateral wall of intelligent door lock body is provided with mobilizable spring bolt, one side of spring bolt is provided with the arcwall face, upper and lower both sides edge of arcwall face all is provided with a plurality of evenly distributed's rectangle groove, the rectangle groove is close to arcwall face one side and is equipped with the opening, the slip is provided with the stopper in the rectangle groove, the inside cavity that is provided with of stopper, one side cavity wall that the arcwall face was kept away from to the cavity is provided with the slide opening, be provided with the strengthening mechanism that makes the stopper reset between slide opening and the rectangle groove. As a further scheme of the utility model, the reinforcing mechanism comprises a slide bar, the slide bar is arranged in the slide hole in a sliding way, both ends of the slide bar extend to the outside of the slide hole, one end of the slide bar positioned outside the cavity is fixedly connected with the rectangular groove, one end of the slide bar positioned in the cavity is fixedly provided with a round block, and one side of the round block away from the slide bar is fixedly provided with a spring. As a further aspect of the present utility model, the diameter of the round block is larger than the diameter of the spring.
