Abstract

The utility model discloses an expansion lock which comprises a connecting lock pole, a lock shell and a lock core. A lock hole is arranged at a side of the shell body and through the hole a lock key is put to the lock core, a sliding groove is arranged at other side of the shell body, and a convex block is thoroughly arranged through the sliding groove and is buckled by the connecting lock pole. The connecting lock pole is provided with connecting pole bodies in complex numbers which are folded and taken in a fixateur inside a storing area of the lock shell. The expansion lock can fold and take in the lock poles in a storing groove to save room; an unlocking and a locking of the expansion lock can be realized only through separating from or combining the concaved groove of the shell body of a third pole body. The utility model is energy-saving, simple and convenient in use, whereof a multi-section and foldable lock pole provides a storing room of the expansion lock for further expansion.

Description

Flexible lock

Technical field

The utility model relates to a kind of lock, particularly a kind of flexible lock.

Background technology

Existing U-shaped lock A, as shown in Figures 1 and 2, it is made up of cylinder shell A2, locking bar A1 and core A4; Wherein an end of locking bar is done binding with rotating part A7 and cylinder shell A2, the other end then is fastened in the set hole slot A6 of cylinder shell A2 with buckling parts A8, insert set lockhole and the rotation lock core A4 of cylinder shell A2 by key A5, can make buckling parts A8 break away from hole slot A6, continue pulling locking bar A1 and can make it break away from cylinder shell A2 for use.Yet existing U-shaped lock A takes up space when taking in, and the design of this locking bar A1 mostly is integrally formed, and its body of rod can't dwindle its volume by mode such as folding when taking in, and the article size that it can lock is also therefore limited.

Summary of the invention

The purpose of this utility model provides a kind of flexible lock that can take in after folding.

The purpose of this utility model is achieved through the following technical solutions:

A kind of flexible lock, it comprises binding locking bar, lock housing and core, one side of its housing is provided with the lockhole of inserting core for key, opposite side then is provided with a chute, have one to be arranged in chute and to be fastened on the projection that links locking bar in it, this bindings locking bar is provided with a plurality of binding bodies of rod bindings and a plurality of connecting rod folded bodies is received into fixed body in the accommodation space of lock housing.

Wherein, the body of rod quantity of binding locking bar is a plurality of.

Wherein, the body of rod of this binding locking bar is shaped as and can piles up square body, trigone or the prismatoid of taking in.

Positive progressive effect of the present utility model is:

1, this flexible lock can fold locking bar and be accommodated in the storage tank, can save the space.

2, the groove of opening and locking and only need make the disengaging of the 3rd body of rod when stretching lock or be incorporated into housing uses comparatively laborsaving and easy.

3, locking bar is divided into multisection type and collapsible, makes the accommodation space of this flexible lock that bigger variation be arranged.

The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

A kind of flexible lock, as Fig. 4, Fig. 5, Figure 6 and Figure 7, wherein should flexiblely lock folding being accommodated in the set storage tank B2 of lock housing B1 of binding locking bar D of B, the opposite side of this lock housing B1 is provided with a chute B3, there is a projection B4 one end to wear this chute B3, the other end then is fastened on the first hole D5 of the first locking bar D1, by passing the side shifting of this projection B4 toward groove B3, can make projection B4 drive binding locking bar D and stretch out storage tank B2, and pass first body of rod D1, second body of rod D2, it is that rotation and expansion are done in the center of circle with fixed body B6 that the 3rd body of rod D3 and the 4th body of rod D4 make it, wherein the end of first body of rod D1 is fixed in the storage tank B2 of lock housing B1, the other end then is linked to first body of rod D2 with fixed body B6, the end of second body of rod D2 is connected with the fixed body B6 and first body of rod D1, the other end then is connected with fixed body B6 and the 3rd body of rod D3, and the end of the 3rd body of rod D3 is connected with the fixed body B6 and second body of rod D2, the other end then is connected with fixed body B6 and the 4th body of rod D4, and the end of the 4th body of rod D4 is connected with fixed body B6 and the 3rd body of rod D3, it is corresponding with the groove B7 that lock housing B1 is provided with that the other end then is provided with the second hole D6, continuation is pushed the 4th body of rod D4 and is made its second set hole D6 enter the set groove B7 of lock housing B1, and further make its engaging, to finish the action of locking; Must take in again when stretching lock B, the 4th body of rod D4 is pulled upwardly, make its second hole D6 break away from the groove B7 of lock housing B1, continuation is that the center of circle rotates with first body of rod D1, second body of rod D2, the 3rd body of rod D3 and the 4th body of rod D4 with fixed body B6, and the shape of utilizing its body of rod can be superimposed characteristic, first body of rod D1, second body of rod D2, the 3rd body of rod D3 and the 4th body of rod D4 are made the superimposed size that makes its reduction in bulk extremely can be accommodated in storage tank B2, continue to pass projection B4 and make its side of shifting to chute B3, and drive binding locking bar D is received into storage tank B2;

As Fig. 8, Fig. 9, Figure 10 and shown in Figure 11, key E is inserted lock housing B1 go up set lockhole C2, this moment core C1 be fastened in link stopper C4 and dead bolt C6 between, and contact in union body C5, again dead bolt C6 be positioned at groove B7 outside, this moment, flexible lock B was an opening, key E is rotated to lock housing B1 one side, make core C1 rotate, and be sticked in the frictional force of dead bolt C6 by core C1, make dead bolt C6 push groove B7, pass the second set hole D6 of the 4th body of rod D4 and contact a side in groove B7, the second hole D6 that passes the 4th body of rod D4 by core C1 will link locking bar D and be fastened in groove B7, must open this flexible lock B system again and see through and rotate key E, core C1 is withdrawed from outside the set second hole D6 of groove B7 and the 4th body of rod D4, can make the 4th body of rod D4 break away from the set groove B7 of housing B1 and make to link lock B and open;

Wherein should further can do anisomerous variation on demand by the flexible binding locking bar D that locks B, it links the accommodation space B5 shape that locking bar D and lock housing B1 constituted then decides according to the variation that links locking bar D, and the object that this kind design can lock this flexible lock B has more diversity.
