Technical Field

The invention relates to the field of locks, in particular to a door lock hand-feeling mechanism.

Background

At present, most locks all have multiple gear switch, for example prevent that the cat eye is unblanked, flee fast and the three function key position commonly used of back lock, but shift the in-process of position switch lock, the gear is not clear, feels not in place and then can trigger the problem of locking by mistake or locking not in place.

Based on the research of the company in the aspect of locks, a mechanism capable of clearly distinguishing gears through hand feeling is developed.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, and provides a door lock hand-feeling mechanism which is stable in structure, good in anti-theft performance, free in switching of three functions of preventing a cat eye from unlocking, quickly escaping and reversely locking, clear in gear, capable of effectively preventing misoperation and solving the problem of insufficient locking.

The invention is realized by the following technical scheme:

the utility model provides a mechanism is felt to door lock hand, includes fixed backplate, fixed backplate top is equipped with function switching board and feels the board, be equipped with upright piece and guide post on the fixed backplate, the guide post passes through the boss and connects on fixed backplate, it is equipped with the wave tooth to feel board one side, opposite side and upright piece elastic connection, be equipped with the slotted hole on the board of feeling, slotted hole and boss horizontal sliding fit.

As an improvement of the scheme, a strip-shaped groove is formed in the function switching plate, a hand-feeling pin is arranged at the bottom of the function switching plate, the strip-shaped groove is matched with the guide column, and the hand-feeling pin is connected with the wavy teeth in a sliding fit mode.

As an improvement of the scheme, the vertical blocks are a pair and fixed on the fixed back plate, and the guide column is fixed between the vertical blocks through the boss.

As an improvement of the scheme, one side of the hand feeling plate is provided with a convex block, and a hand feeling spring is arranged between the convex block and the vertical block.

As an improvement of the scheme, the end part of the hand feeling plate is provided with a pair of guide legs which are matched and connected with the pair of vertical blocks.

Compared with the prior art, the door lock hand-feeling mechanism has the advantages of stable structure, good anti-theft performance, free switching of three functions of preventing the cat eye from unlocking, quickly escaping and reversely locking, clear gears, effective prevention of misoperation and solving of the problem of insufficient locking.
