Description

Exempt from the mortise lock that key is locked

The utility model relates to a kind of door lock, particularly a kind of locking without the mortise lock of key.

Technical background:

00227206 patent application application number was disclosed in the Chinese patent CN2421379 number bulletin is on January 22nd, 2000, a kind of three dead bolt structure of convenient lock is automatically disclosed on this application, this conveniently being locked in when using need not be used key, by oblique tongue collision brake plate main dead bolt is being decontroled at closing time, main dead bolt ejects outside the lock housing under the effect of spring force and reaches self-locking purpose; The shortcoming of this lock is that the user can automatically lock at every turn at closing time, and often the someone place of coming in and going out is very inconvenient for office etc.

Summary of the invention:

The purpose of this utility model is exactly to be not easy to some often problem of using of the someone place of coming in and going out in the above-mentioned automatic locking in order to solve, and proposes a kind of mortise lock that at closing time need not key just can lock fast.

Technical scheme:

The purpose of this utility model is achieved in that a kind of mortise lock that key is locked of exempting from, and comprising: lock housing, square tongue, tapered end, outer knob, outer thumb wheel, middle thumb wheel; It is characterized in that: be installed in the outer knob on the outer drawing board outdoors and be set with tapered end, the outer knob inboard is provided with a hollow square shaft, one cross section is that the core that an end of the sword iron of rectangle passes on the hollow and tapered end of this square shaft links, and cross section is that the other end of the sword iron of rectangle stretches in the lock housing and in the hole that matches with it on the thumb wheel in inserting; Thumb wheel axially stretches out a driving lever in outer, middle thumb wheel center, in the strip hole of offering on this driving lever side of stretching into tongue; Thumb wheel outside between middle thumb wheel and outer knob, being provided with, outer thumb wheel be provided with outer knob on the square hole that matches of square shaft; Outer thumb wheel extends radially a wing, this wing is arranged in the rear side of the driving lever on the described thumb wheel or the rear side of square tongue, its effect is that this wing side of driving tongue moves outside lock housing when the direction rotation is locked in outer thumb wheel upper edge, and be idle running when outer thumb wheel backward rotation, the driving effect of promptly outer thumb wheel the other side tongue is unidirectional.

Describedly exempt from the mortise lock that key locks and it is characterized in that: be provided with limited post in the described outer panels to limit the rotational angle of rotating outer knob.

Describedly exempt from the mortise lock that key locks and it is characterized in that: the core on the described tapered end and the connected mode of sword iron are to have a counterbore on core, and the counterbore inwall entad stretches out one group of platform, and sword iron one end stretches in this counterbore; Stir the sword iron rotation and drag driving lever with thumb wheel in driving square tongue is opened or closed by the platform of dialling in this counterbore during rotation lock core.

Operating principle: thisly exempt from mortise lock that key locks at closing time, only need rotate outer knob outdoors, the square shaft of outer knob drive outer thumb wheel rotate the wing that makes on the outer thumb wheel stir on the middle thumb wheel driving lever or directly the side's of stirring tongue square tongue release lock housing is locked outward, its process need not just to finish locking function with key; Though sword iron together rotates in the above-mentioned process of locking, but because of dialling between platform and sword iron in the counterbore on the core is provided with the room, and outer knob is located at the restriction of the limited post on the outer panels and can only be rotated a suitable angle, so outer knob forward or reverse in limited scope of activities all can not be unblanked after square tongue stretches out outside the lock housing, that is to say that outer thumb wheel is unidirectional (can only the side's of driving tongue stretch heart lock housing lock the invalid idle running of its reciprocal rotation outward) by stirring of driving lever the other side tongue; During rotation lock core behind the insertion key (can have relative motion between core and outer knob this moment), drive sword iron and rotate after core turns over certain angle, the driving lever side of the driving tongue in making on the thumb wheel bounces back in lock housing and unblanks.

Owing to adopted technical scheme described in the utility model, thisly exempt from the mortise lock that key is locked, only need rotate outer knob outdoors at closing time, and be just to rotate outer knob at closing time, with common the same need of mortise lock door is not with at closing time and is got final product, open the door, all need not change at closing time people's the custom of locking a door, use very convenient.
