Description

A kind of lock device of zipper lock

The utility model relates to a kind of slide fastener that is used for, especially for the lock device of the slide fastener on case and bag or the clothing pocket.

Usually slide fastener does not have special-purpose lock, for slide fastener used on the case and bag, uses common padlock sometimes, and volume is big, profile is not attractive in appearance, very impracticable.For the slide fastener on the clothing pocket, then there is not available lock basically.

To this, U.S. Pat 4514884 once proposed a kind of lock that is exclusively used on the slide fastener, and it mainly is made up of two slide fastener bodies and a lock body, and lock body is connected with one of them slide fastener body, during use, was fastened on and realized locking on another slide fastener body.But its lock body part part is more, and structure is complicated, and its folding mainly is that confidentiality is poor, so lacks practicality by the key realization with a kind of shape.

The utility model is exactly that a kind of lock device that can be used for simple in structure, the both artistic and practical zipper lock with certain confidentiality that volume is little on the slide fastener will be provided.

The purpose of this utility model is to realize like this, a dead bolt that directly stirred by key and that supported by back-moving spring is promptly arranged in lock body, its front end directly is against one also on the lock bridge that has breach by the back-moving spring support, when sealed, press the exposed junction of lock bridge, its other end is inserted in the annular distance of slide fastener body, simultaneously, dead bolt is stuck in the indentation, there of lock bridge under spring action, then lock bridge can not be return, and realizes locking.During unlatching, the rotation key is stirred dead bolt and is left breach, and lock bridge is return the realization folding under spring action.And position and quantity by predefined projection on the lock body inner frame body shape that changes key, to realize its confidentiality.

Device of the present utility model, because its compact conformation, number of parts is few, strong security helps the miniaturization of volume, and good looking appearance, be convenient to decorate, therefore, not only can be used for the slide fastener of case and bag class, and can be used on the slide fastener of clothing pocket and other small articles as locking device and decoration.

Device of the present utility model is to be provided by following examples, and Fig. 1 is the top plan view of the opening of the utility model device.3 is base plate among the figure, and it has a socket 31,2 is housing, and it is fastened on the base plate 3, and the one side has a keyhole 21, and opposite side has a hole 22, is used for stretching out of lock bridge 6.Inside and keyhole 21 corresponding sections at housing 2 are fixed with support body 4, an end of support body 4 have can be by reciprocating dead bolt 5 slotted eye 42, be provided with projection 41 at its other end, by changing 41 position and quantity, shape that can corresponding change key.The front end 51 of dead bolt 5 is against on the lock bridge 6 under the effect of back-moving spring 7.

Fig. 2 is the top plan view of lock body lock-out state.When needs lock, at first lock body is fastened on the slide fastener body and (does not draw among the figure), then slide fastener ring 9 extend in the housing 2 by socket 31, press the exposed junction 62 of lock bridge 6, then the front end 63 of lock bridge is inserted in the hole 91 of ring 9, and this moment, the front end 51 of dead bolt 5 inserted in the breach 61 of lock bridge 6 under the effect of back-moving spring 7, lock bridge 6 is blocked and can not return, realize locking.

When needs are opened again, insert key (drawing among the figure) and rotate it in support body 4 by keyhole 21, then key promotion dead bolt projection 52 is moved whole dead bolt 5 backward, withdraws from lock bridge breach 61, lock bridge 6 promptly withdraws from annular distance 91 under back-moving spring 7 effects, realize opening.After extracting key out, lock body is got back to Fig. 1 state.

In addition, among the figure ring 8 be used for the slide fastener ring of another slide fastener body joining.Also have, for the shape of lock body, also can be other arbitrary shapes, be not subjected to the diagram restriction, the outer surface of lock body can also carry out various decorations, is advisable with both artistic and practical in a word.Also can be divided into two springs for back-moving spring 7, be advisable so that produce.

Claims (3)

1, a kind of lock device of slide fastener, it is characterized in that this device mainly comprises a base plate 3 and a housing 2 that has keyhole 21 that has socket 31, and having one to have the movably support body 4 of dead bolt 5 in the internal fixation of housing 2, the front end 51 of dead bolt 5 directly is against on the lock bridge 6 that has breach 61.

2, according to claim 1 described device, the reseting movement that it is characterized in that dead bolt 5 and lock bridge 6 all is promoted by spring 7.
