Abstract

The utility model relates to a chain lock with double lock tongue mechanism, which comprises a lock body with double socket, a flexible chain and a plug at the end of the chain. In addition to a socket B of the lock tongue mechanism controlled by a key, the lock body also is provided with a socket A of the manual lock tongue mechanism comprising a spring, a lock tongue and a handle. The mechanism is characterized in that a long round cavity chamber is opened in the lock body. The socket A that is vertical to the axes of the cavity chamber and is provided for inserting the plug at the end of the chain and an axle groove are separately arranged at both ends of the cavity chamber. The lock tongue takes a column shape and matches to the sides of the cavity chamber. One end of the lock tongue takes on incline shape and the other end is connected with the handle. The spring is pressed in the space formed by the cavity chamber of the lock body and the handle. The handle is inserted in the axle groove of the lock body with slip and match state. The invention provides the cyclists with the convenience of releasing the lock without using the key so much. When the bicycle is anti-theft, the plug at the end of the chain is inserted in the socket B, whereas, the socket at the end of the chain can be inserted into the socket A of the manual lock tongue moving mechanism.

Description

Double lock tongue mechanism chain lock

Affiliated technical field

The utility model relates to a kind of lock, especially is usually used in a kind of chain lock of bicycle.

Background technology

As everyone knows, chain lock can be easily locks together things such as bicycle and ground post, beam, tree, in order to vehicle anti-theft, so the chain lock application quantity is very big.But it still has improvements; When it was carried with car, people still needed it is locked on the car, and waiting to stop, people also need to open it with key again when latching.It is contemplated that if set up the mechanism of the manual dead bolt of cover motion again on such lock body, people needn't not implement the process lock opened with key again when lock has antitheft task, this double lock tongue mechanism chain lock bring some convenient can for people by bike.

Summary of the invention

The objective of the invention is: release a kind of more convenient double lock tongue mechanism chain lock that uses.

A kind of double lock tongue mechanism chain lock, it is to be made of the lock body of twin jack, flexible chain, end of the chain plug; Except that the jack B that is provided with traditional dead bolt motion of controlling by key, set up by spring, dead bolt again, dialled the jack A of the manual dead bolt motion that handle forms on the lock body; This mechanism is; Have one section plenum chamber that circle is microscler in addition in lock body, be respectively equipped with at the two ends of this plenum chamber with its axis and be the jack A that inserts for end of the chain plug of vertical configuration and axial groove; Dead bolt is the column type shape, and is with the inner peripheral surface of its plenum chamber of lock body and is slidingly matched, and the one end is beveled, the other end with dial handle and be connected; Spring is a helical form, and it is compressed in the plenum chamber of lock body and dials in the space that handle constituted; Dial handle and be embedding in its axial groove of lock body of the shape that is slidingly matched.

Bicycle does not need when antitheft, and this lock is in and is carried shape, and at this moment end of the chain plug can insert by among the manual dead bolt motion jack A; When this lock need be used for locking car, end of the chain plug is inserted with among the jack B at its place of dead bolt that key controls.

The beneficial effects of the utility model are; Few convenience with key driving lock is provided for people by bike.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model partial schematic sectional view.

Fig. 2 is manual its structural representation of dead bolt motion.

Among each figure, 1, lock body, 2, flexible chain, 3, end of the chain plug, 4, manual dead bolt motion, 5, plenum chamber, 6, spring, 7, groove, 8, dead bolt, 9, dial handle, 10, keyhole.

The specific embodiment

Double lock tongue mechanism chain lock as shown in Figure 1 is that the jack B of the dead bolt motion controlled by lock body (1), flexible chain (2), end of the chain plug (benefit), manual dead bolt motion (4), keyhole (10) with by key constitutes; It will be same as on the lock body (1) by the dead bolt motion and the manual dead bolt motion (4) (as shown in Figure 2) of key control.Manual dead bolt motion (4) by plenum chamber (5), spring (6), groove (7), dead bolt (8), dial handle (9), jack A constitutes, its dead bolt (8) is with plenum chamber (5) inner circumferential surface and is slidingly matched; Dead bolt (8) is connected with group handle (9); Spring (6) is placed in plenum chamber (5) and dials in the space that handle (9) constituted; Dialling handle (9) is at groove (7) and is slidingly matched.

As people by bike the time, end of the chain plug (3) is inserted among the jack A, onboard the lock lock.When the lock car will be used for when antitheft, available hand is stirred and is moved after handle (9) recompresses, makes dead bolt (8) with spring (6), and the end of the chain plug (3) in the jack A is extracted, and then is inserted among the jack B.When people unblank, with traditional approach key is inserted the interior also turn key of keyhole (10) and get final product.
