Abstract

The utility model relates to a chain lock which is used for locking portable objects to prevent illegal move and is convenient to carry. The utility model comprises a chain and a plug and a lock head which are connected with both ends of the chain respectively. A plug hole matching with the plug is arranged on the lock head, and the lock head is fixed in an outer shell. One end of the chain, which is provided with the plug, is penetrated out of the outer shell. Holes whose positions are corresponding to the positions of a lock core hole and an inserting hole are arranged on the outer shell. In the utility model, the outer shell is additionally arranged on the exiting chain lock, so the chain can be placed in the outer shell when the chain lock is not used, and therefore, the utility model has the characteristic of portability.

Description

Chain lock

The utility model is a kind ofly to be used for the locking portable object in case illegally move and portable chain lock.

It is very general using chain lock locking bicycle or motorcycle.For strengthening anti-theft effect, people often adopt general bicycle or lock for motorcycle to add the double insurance method of a chain lock, with chain lock vehicle and fixture are on every side locked together.But present chain lock all is not easy to carry, and chain lock can be lost because of carelessness sometimes.

The purpose of this utility model is: design a kind of portable chain lock.

The utility model comprises a chain and the plug and the tapered end that link to each other with its two ends respectively, the plug hole that matches with plug is arranged on the tapered end, tapered end is fixed in the shell, and the end that chain has plug passes shell, has the hole corresponding with lock core hole and jack position on the shell.The utility model has added a shell at existing chain lock, thereby chain can be put into shell when chain lock does not use, and this just makes it have portable characteristics.Shell of the present utility model can be made up of housing that matches and cap, and the size of shell nozzle is greater than the size of tapered end, and tapered end is fixed on the openend of housing, and its plug hole is positioned at the opening part of housing, and chain is passed by the space between tapered end and housing.Housing and cap are preferably in a side and link mutually and it is become one in addition.If a side of shell has the clamping plate that are connected with it by screw, then the utility model can directly be fixed with on bicycle or the motorcycle.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the phantom of the utility model embodiment front view;

Fig. 2 is the phantom of Fig. 1 lateral view;

Fig. 3 is the A-A view of Fig. 2;

Wherein, 1-cap, 2-chain, 3-plug, 4-tapered end, 5-housing, 6-clamping plate, 7-plug hole.

The utility model is made up of tapered end 4, clamping plate 6 that shell, chain 2, plug 3 have lock core and plug hole.Wherein, shell comprises mutually the housing 5 and the cap 1 of hinge joint, and the clamping plate of being made up of two intermediate plates 6 are by the side of screw at housing 5.The another side of housing 5 has lock core hole, opening one side of housing 5 adapts with the size of tapered end 4, and another side is greater than the size of tapered end, and tapered end 4 is fixed on the opening part of housing 5, and the one side that has plug hole is outside, and the lock core on the tapered end 4 is corresponding with the lock core hole position on the housing 5.The two ends of chain 2 are connected with tapered end 4 and plug 3 respectively, and the end that it has a plug passes the back by the tapered end 4 and the gap of housing 5 and the plug hole on the tapered end 4 cooperates.

Under obsolete state, plug of the present utility model can be inserted in the plug hole on the tapered end, and chain is put into shell, again with the cap closure.The utility model can directly be put into pocket and carry, and also can be fixed on bicycle or the motorcycle by clamping plate.
