Description

A kind of mechanical lock

Technical field

The utility model relates to lockset, especially a kind of mechanical lock for mechanical lock or smart lock.

Background technology

At present, do on the market the producer of locking a lot, a part is engaged in mechanical lock, the smart lock that a part grows up on the basis of mechanical lock.Because smart lock relates to mechanical control section, just there are a lot of drivers and control panel to be placed on lock body the inside, cause lock body integral body partially thick.But some thickness gates very thin (particularly timber), so for being installed, lock body need on door leaf, draw very large hole when mounted.So likely make door leaf lose enough intensity, particularly veneer door, brings certain potential safety hazard to user's use.

And mechanical lock structure is comparatively simple, but the lock body of mechanical lock is difficult to smart lock lock body, is difficult to mechanical lock, because the structure of mechanical lock and smart lock is different for the lock body of smart lock.Master lock tongue and latch bolt are installed on lock body, and the master lock tongue on mechanical lock is to control by lock core, is to open or closed master lock tongue with key, latch bolt is to control by handle, the effect of latch bolt is to allow door-plate fix on doorframe, does not play locked effect, and the control of general master lock tongue and latch bolt separates.And smart lock is different, if at present conventional Fingerprint Lock, kayser, coded lock etc., most smart lock is there is no handle, directly controls the keying of master lock tongue and latch bolt by driver and control panel, therefore mechanical lock and smart lock difference structurally, make it cannot be general.

Utility model content

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of mechanical lock is provided, and it is simple in structure, thin thickness, and be applicable to being respectively used to mechanical lock and smart lock.

The utility model solves the technical scheme that its technical problem adopts: this mechanical lock, comprise housing, master lock tongue and latch bolt are installed in housing, the inner of master lock tongue is connected on slide plate, slide plate is laterally slidably mounted in housing, and the inner of latch bolt connects slide bar, and on slide bar, cover has back-moving spring, back-moving spring outer end withstands on latch bolt inner face, and back-moving spring the inner withstands on the baffle plate that is fixed on housing; In housing, be provided with lock core mounting groove and handle mounting blocks, handle mounting blocks rotates in holder housing, the centre of handle mounting blocks has for the installing hole of handle is installed, handle mounting blocks is provided with fork outward, upper fork is rotatably assorted outside handle mounting blocks, the medial surface of upper fork is provided with deep-slotted chip breaker, handle mounting blocks is provided with the fastener being equipped with in deep-slotted chip breaker, upper fork outside is provided with extension, extension is stuck on the catch of slide bar outer end, on housing, have chute, catch is slidably mounted in chute; At the rear of slide bar, be provided with the limiting plate being fixed in housing; Upper fork is also connected with a connecting rod, and the other end of this connecting rod is connected to slide plate.This structure design is ingenious, and the upper fork on handle mounting blocks and the effect of lower fork realize the positive and negative rotation of handle all can drive the unlatching of latch bolt, during like this as mechanical lock, is convenient to open the door; And by connecting rod, connect on slide plate on upper fork, make like this master lock tongue link together with latch bolt, while moving in master lock tongue, drive in latch bolt and move, reach the effect of opening the door fast.

For further perfect, on connecting rod, have regulating tank, in regulating tank, be provided with the fixture that is fixed on slide plate.Connecting rod is to be fixedly mounted on slide plate by fixture, and the regulating tank on connecting rod plays the length that regulates shrinking connecting-rod to connect.While shortening the length that connecting rod connects, make master lock tongue and latch bolt interlock, and the length that prolongation connecting rod connects or while unclamping fixture makes master lock tongue and latch bolt that interaction relation not occur.

Handle mounting blocks is provided with torsion spring and lower fork outward, and torsion spring set is outside handle mounting blocks, and the straight section portion at its two ends is stuck on the keeper of housing internal projection, and lower fork is fixed on outside handle mounting blocks and is provided with the projection between the two straight section portions of insertion; Housing is provided with the activity template being rotatably connected in housing, and one end of activity template stretches out and is stuck on lower fork, and the other end stretches out and is stuck on slide bar;

In housing, be also provided with and dial catch, dial catch longitudinal sliding motion and be arranged in housing, the side of slide plate is provided with row's projection, dials catch and is provided with the draw-in groove coordinating with projection, and in housing, be provided with the stage clip that the draw-in groove on group catch is pressed together on to projection.Like this when dialling projection on slide plate of draw-in groove on catch, locked master lock tongue, this structural strengthening master lock tongue locking resistance of failure, improve user's use safety.

The effect that the utility model is useful is: lock body of the present utility model, by the change of simple and mechanical structure, can be applicable to standard machinery lock, also can be applicable to smart lock (Fingerprint Lock, coded lock, kayser etc.).Handle mounting blocks in lock body rotates and all can drive in latch bolt and move at different directions, and master lock tongue in move and can drive latch bolt to move in together, reach the requirement of smart lock intelligent drives.This lock thickness is very thin, and lock body door leaf need not be drawn very large hole for lock body is installed, and guarantees door leaf intensity, for user security is used, provides safeguard, and has strengthened master lock tongue locking resistance of failure simultaneously, improves user's use safety.
