Description

Lock set

Technical Field

The invention relates to the field of door locks, in particular to a lockset.

Background

Existing electronic intelligent door locks are subdivided into fully automatic and semi-automatic types. The full-automatic electronic intelligent door lock is further divided into a single machine version and a networking version, the motor directly drives the lock tongue of the lock body, and a user only needs to open the door after the authentication of the identity authority is successful without carrying out additional mechanical actions, or closes the door when leaving home, and the lock body and the lock tongue are directly driven by the motor to be locked. The semi-automatic electronic intelligent door lock is different from the full-automatic electronic intelligent door lock in that when a user returns home, the user needs to pass through authentication verification, the user pushes down or pushes the front handle, the lock tongue of the lock body is pulled back through the linkage structure, then the door pushing action is performed to realize door opening, or under the condition that the user leaves home, the user lifts or pushes and pulls, and the lock tongue of the lock body is pushed out manually through the linkage structure, so that the door is closed.

The clutch structure of the semi-automatic electronic intelligent door lock is commonly known as two design modes in the door lock industry, wherein one clutch structure is a front clutch structure, and the other clutch structure is a rear clutch structure. The semi-automatic electronic intelligent door lock with the front clutch structure is researched, developed, manufactured, maintained after sale and simplified, low in cost and low in technical content. But the semi-automatic electronic intelligent door lock adopting the front clutch structure is the least safe, lawbreakers can easily pass square steel or tools similar to the square steel by violently destroying the front panel of the door lock outdoors, and can pull back the lock tongue of the lock body under the condition of no identity verification, thereby realizing door opening and house entering.

At present, the semi-automatic electronic intelligent door lock adopting the rear clutch structure almost all realizes the series connection action of opening and closing the door through the linkage of the front panel connecting rod and the rear clutch structure, the connecting rod and the rear clutch structure are all independently arranged, a plurality of holes are needed to be formed in the door plate at the moment, one hole is used for connecting the front and rear handle and the connecting rod, one hole is used for communicating the rear clutch structure, the whole appearance of the door plate is caused, the integrity and the consistency of the door plate structure are damaged, and meanwhile, the labor cost of certain installation and after-sales maintenance is additionally generated. In addition, the door lock thus arranged requires one hand to operate the rear clutch structure and one hand to operate the door handle when a user goes out, which causes inconvenience in operation.

It is worth mentioning that the door plant is equipped with the cat eye that glass or plastics were made on the current door plant, and the vain is through destroying the cat eye, and a long stick is gone into from the cat eye again, just can rotate the handle and open the door. In order to prevent illegal unlocking of the door lock through the peep hole, some door locks are provided with safety buttons for locking handles, and the door lock can be unlocked only by unlocking the safety buttons in a complex mode, so that the problem of peep hole unlocking prevention is solved, but inconvenience of door opening of a user is caused.
