Abstract

The utility model provides a lock body code change mechanism of a push-button mechanical coded lock. The mechanism comprises a pass pole, a transmission core, a fixed core and a control mechanism for changing code; wherein, a code changing head is molded on the pass pole, and one end of the code changing head is inserted into the internal cavity of the code changing button from the bottom of the code changing button; engaging troughs are molded at the two sides of the side wall of the main body of the pass pole, a positioning locking board of the transmission core is correspondingly inserted into and connected with the engaging troughs, the bottom of the transmission core is inserted into and connected with the fixed core while the fixed core is fixed with the motherboard of the lock body by rivets; the control mechanism for changing code is arranged on the lower bottom surface of the baseboard of the lock body and consists of a limiting board and a displacement piece of the limiting board matched with and installed on the limiting board. After adopting the technological proposal of the code change mechanism of the utility model, the baseboard of the lock body need not to be removed to change the lock of each push button one by one while changing the code in the prior art, thus realizing the beneficial effects of rational structure and convenient code changing.

Description

A kind of lock body escape mechanism of key-type mechanical puzzle lock

Technical field:

The utility model relates to the coded lock technology field, refers in particular to a kind of lock body escape mechanism of key-type mechanical puzzle lock.

Background technology:

Known in the industry, push-button puzzle lock good confidentiality, stable performance, its do not dismantle lockset just can change the function of password use particularly convenient, but also there is certain problem in the escape mechanism of existing lock body, though promptly need not integral body pull down escape, but also to pull down the base plate in the door during escape, corresponding button is operated escape one by one, therefore also have certain inconvenient part.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of mechanism rationally, the escape lock body escape mechanism of key-type mechanical puzzle lock easily.

For achieving the above object, the technical scheme that the utility model provides is: a kind of lock body escape mechanism of key-type mechanical puzzle lock, include channel post, the transmission core, fixed core, the escape controlling organization, form the escape head on the channel post, one end of escape head is inserted the inner chamber of escape button by the bottom of escape button, the both sides of channel post main body wall form buckling groove, the locating clamp plate of transmission core is corresponding pegs graft with buckling groove, the bottom of transmission core and fixed core are pegged graft, fixed core is fixed by rivet and lock bottom plate, the escape controlling organization is installed in the bottom surface of lock bottom plate, and the escape controlling organization cooperates the limiting plate displacement member of installing to form by limiting plate and with limiting plate.

The both sides of described limiting plate cooperate with fixed core and form concavo-convex position, the limiting plate displacement member be a gear, cooperate this gear forming that the teeth groove position is arranged on the plate body of limiting plate.

The both sides of described limiting plate cooperate with fixed core and form concavo-convex position, and an end of limiting plate is connected with lock bottom plate by back-moving spring, and described limiting plate displacement member is an eccentric cam, and this eccentric wheel of cooperation is reserved with the eccentric cam shift holes on the plate body of limiting plate.

Fixed core is placed in the endoporus of limiting plate, and the limiting plate displacement member is a gear, cooperates this gear forming that the teeth groove position is arranged on the plate body of limiting plate.

After the utility model adopts technique scheme, need not to pull down as prior art lock bottom plate during escape each button is changed lock one by one, only need the rotational displacement part, displacement member moves and forces the rotatable position of limiting plate to move to the fixed core place, make fixed core be in rotatable state, user's direct control escape button can be realized escape like this, very convenient to use, after escape is finished, the rotational displacement part, displacement member is by forcing the limiting plate playback, and this moment, fixed core can't be rotated, and promptly can't carry out escape.

The specific embodiment:

See accompanying drawing 1～shown in Figure 5, preferred embodiment of the present utility model is mainly by escape button 1, channel post 2, transmission core 3, fixed core 4, the escape controlling organization, form escape 5 on the channel post 2, one end of escape head is inserted the inner chamber of escape button by the bottom of escape button, the both sides of channel post main body wall form buckling groove 6, locating clamp plate 7 corresponding and buckling groove 6 grafting of transmission core, the bottom of transmission core and fixed core 4 are pegged graft, fixed core 4 is fixing by rivet and lock bottom plate 8, the escape controlling organization is installed in the bottom surface of lock bottom plate, the escape controlling organization cooperates the gear of installing 10 (being the limiting plate displacement member) to form by limiting plate 9 and with limiting plate, described limiting plate both sides cooperate with fixed core 4 and form concavo-convex position 11, mate gear 10 forms teeth groove position 12 on the plate body of limiting plate.During escape, transmitting gear 10, force the recess of the concavo-convex position of limiting plate 9 to move to fixed core 4 places, fixed core 4 can be in rotary state, and can press the 1 disposable operation escape of escape button this moment, after escape finishes, handsetting gear 10, make protruding fixed core 4 places that are moved to of the concavo-convex position of limiting plate 9, fixed core 4 can not be rotated, promptly can not escape.

See Fig. 6, shown in Figure 7, another embodiment principle of the present utility model is identical with above-mentioned preferred embodiment, difference is that an end of described limiting plate is connected with lock bottom plate 8 by back-moving spring 13, described limiting plate displacement member 10 is an eccentric cam, cooperates this eccentric wheel to be reserved with eccentric cam shift holes 14 on the plate body of limiting plate.

See Fig. 8, shown in Figure 9, another embodiment principle of the present utility model is identical with above-mentioned preferred embodiment, difference is that fixed core 4 is placed in the endoporus 15 of limiting plate, and limiting plate displacement member 10 is a gear, cooperates this gear forming that teeth groove position 12 is arranged on the plate body of limiting plate.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
