Description

A kind of lock body of door lock

Technical field

The utility model relates to a kind of lock body of door lock.

Background technology

At present, the lock body great majority of door lock insert the transmission mechanism of the drive link driving lock body the inside of tapered end drive tapered end afterbody square tongue are released or the retraction lock housing with tapered end by key on the market, reach the purpose of locking a door or opening the door; This structure is comparatively complicated, uses tapered end, and cost is higher.

In addition, some lock body applied cryptography sheets cooperate with key, the cancellation tapered end, but drive mechanism is also complicated, cost is high, and function is imperfection also, does not have the decoration worker that the differentiation of the engineering key of door lock and user user's key of opening door lock when using is installed, and is unfavorable for that namely the installation of door lock also is not easy to user's use.

Summary of the invention:

The purpose of this utility model provide a kind of simple in structure, cost is low and the lock body of door lock of operation simple and convenient.

The technical solution of the utility model is achieved in that

A kind of lock body of door lock, comprise lock housing, the handle for driving assembly, the latch bolt assembly, side's tongue assembly and user's key, the handle for driving assembly, latch bolt assembly and square tongue assembly are installed on the lock housing, the described side's tongue assembly side's of comprising hyoplastron and square tongue, be provided with the bayonet socket of stirring that cooperates with user's key on side's hyoplastron, chute on side's hyoplastron is enclosed within on the lead of lock housing protrusion, it also comprises some on the side's of the being placed on hyoplastron cipher chips that are superimposed together, gathering sill is set on the cipher chips, gathering sill is nested on the lead of lock housing protrusion, draw-in groove is set on the cipher chips, the fixture block that side's hyoplastron afterbody arranges perk is embedded into the draw-in groove the inside, and cipher chips one side is stretched out cylinder, and cover has spring on the cylinder, spring one end withstands on the baffle plate that protrudes on the lock housing, and the spring other end withstands on the cipher chips;

When being inserted and rotated user's key, the tartar of user's key front end promotes cipher chips, makes the cipher chips against the force of the spring and move, makes the draw-in groove alignment on each cipher chips that is superimposed together, and the side's of making hyoplastron afterbody fixture block can move around inside draw-in groove; In addition, stir bayonet socket on the tartar side of the being inserted into hyoplastron of the front end of user's key, thereby the side's of drive hyoplastron and square tongue move together, the side's of making tongue stretches out lock housing;

On the tartar side of the being inserted into hyoplastron of the front end of counter-rotating user key user key, stir bayonet socket, thereby the side's of drive hyoplastron and square tongue move together, the side's of making tongue retraction lock housing, at this time extract user's key out, under the effect of spring, cipher chips is relatively moved, the draw-in groove on each cipher chips that is superimposed together is staggered, the side's of making hyoplastron afterbody fixture block is stuck can not to move around in the draw-in groove the inside.

Technique scheme can be further improved by following measure:

Described draw-in groove is " king " font.

Be provided with an engineering spoon opening mechanism on the described lock housing, this project spoon opening mechanism comprises fork and sliding bar, sliding bar is nested in the guide-track groove the inside that arranges on the lock housing and can moves around, the axis of guide borehole jack of fork is contained in the rotating shaft of lock housing protrusion, can be along shaft swing, moving the buckle that the left side is protruded at torsion spring effect draft link withstands on the reference column on the lock housing, the bottom of fork withstands on an end of sliding bar, sliding bar can not be moved, the grab of the protrusion on the sliding bar is embedded into a side of the hook groove on each cipher chips that is superimposed together, make each cipher chips against the force of the spring and mobile and make draw-in groove alignment on each cipher chips that is superimposed together, the side's of making hyoplastron afterbody fixture block can move around in the draw-in groove the inside;

Insert the engineering key, make the bayonet socket of stirring on the tartar side of the being inserted into hyoplastron of front end of engineering key, thereby the side's of drive hyoplastron and square tongue move together, the side's of making tongue stretches out or the retraction lock housing;

When inserting user's key and rotating, the tartar of user's key front end is stirred the drive block that fork one side is protruded, making fork overcome the torsion spring resistance moves down, the buckle of fork is broken away from the reference column and swing, the bottom of fork breaks away from an end of sliding bar, sliding bar can be moved freely, and each cipher chips can be free to slide under the spring action, and engineering spoon opening mechanism lost efficacy.
