Abstract

The utility model relates to an inserting padlock with a double linked self-locking function for vehicles, comprising a locking head and a U-shaped inserting handle. The utility model is characterized in that a chain is connected with the locking head; the front end of the chain is provided with a self-locking plug; the diameter of the self-locking plug is less than the hole diameter of the inserting hole on the locking head; an annular locking groove which is matched with the end part of the inserting head of the U-shaped inserting handle is processed on the self-locking plug. The utility model has the advantages that the chain is added on the existing cycle lock to have the double linked self-shrinking function with science and reasonableness; one lock can be used with the functions of two locks; the utility model also has the advantages of convenience, practicality, improvement of safety factor, anti-prying performance, anti-shifting performance, anti-disassembly performance, anti-directly moving performance, etc.

Description

Slotting formula Vehicle lock with duplex auto-lock function

The utility model relates to a kind of bicycle Vehicle lock, relates in particular to a kind of slotting formula Vehicle lock with duplex auto-lock function.

As everyone knows, the stolen problem of bicycle is a social at present outstanding problem, at this problem, some inventors have been bicycle designs multiple theftproof lock, insert the formula Vehicle lock and promptly be wherein a kind of, and be widely used, this lock comprises a tapered end and slotting composition of a U-shaped, as shown in Figure 1.Tapered end is installed on the sidecar frame, and U-shaped is inserted and inserted the tapered end lockhole pass the vehicle wheel bar from the opposite side vehicle frame, thereby lock is lived, and when opening lock, just U-shaped is inserted taking off, and is placed in the jack on the tapered end.Though the lock of this structure has tangible theftproof performance than in the past Vehicle lock, also has weak point, stealer is often directly moved car, picking lock slowly again to the somewhere, or with saw blade U-shaped is inserted sawed-off.Therefore, now a lot of people adopt two locks, a lock wheel, another chain lock then locks together a car and a fixture, or with lock together with two of passerbys or three persons, the car stealer can't be moved car easily, the theftproof of this mode is no doubt good, but the trouble that seems, not enough science.

A kind of slotting formula Vehicle lock that the purpose of this utility model designs at existing problem in the above-mentioned prior art just with duplex auto-lock function, this Vehicle lock is rational in infrastructure, design ingenious, only on existing lock, increase by a chain, can play duplex from contracting function, a lock has played the function of two locks, and more scientific and reasonable, makes the car stealer forbidding.

The purpose of this utility model realizes by following measure: the slotting formula Vehicle lock that originally has the duplex auto-lock function comprises tapered end and slotting composition of U-shaped, wherein: on tapered end, be connected with a chain, the chain front end is one from locking bolt, from the diameter of locking bolt less than tapered end on the jack aperture, on locking bolt, be processed with one and insert the annular lock groove that plug ends is matched with U-shaped.

In the utility model, on tapered end, be processed with one and insert the hole from locking bolt.

The advantage that the utility model is compared with prior art possessed is: is skillfully constructed, and scientific and reasonable, only on existing lock, increase by a chain, can play duplex from contracting function, a lock has played the function of two locks, and convenient and practical, safety factor greatly improves.Originally be locked in when using, chain and its thing are worn the company back in the jack on locking bolt insertion tapered end of front end, again U-shaped is inserted (with same way as in the past) inserted to lock in the tapered end lockhole and got final product, U-shaped was inserted plug ends was headed in the annular lock groove on locking bolt this moment, from locking bolt by locking, can't extract, thereby reach the duplex auto-lock function.When lock is opened, can inserting in the hole of processing in addition on the tapered end will be inserted in from locking bolt.When using this lock, chain can be linked to each other with a fixture; Also can with chain and another not acquaintance's bicycle lock link, as the U-shaped that is through its lock insert in, or in the dead bolt (other common lock), and do not influence the unlatching voluntarily of this car, chain can be deviate from voluntarily after this car is opened.Use this chain also can on self wheel, behind a circle, insert locking in the tapered end jack again, increase safety factor.Because the above-mentioned advantage of this lock once putting on market, will have the very strong market competitiveness, considerable benefit.

The drawing of accompanying drawing is described as follows:

Fig. 1 is existing configuration diagram of inserting the wushu Vehicle lock.

Fig. 2 is the configuration diagram of a kind of embodiment of the utility model.

Fig. 3 is the configuration diagram of the another kind of embodiment of the utility model.

The utility model is done a description below in conjunction with (accompanying drawing) embodiment:

As shown in the figure: the slotting formula Vehicle lock that originally has the duplex auto-lock function comprises tapered end (1) and slotting (2) composition of U-shaped, wherein: on tapered end, be connected with a chain (4), the chain front end is one from locking bolt (5), from the diameter of locking bolt less than tapered end on jack (3) aperture, on locking bolt (5), be processed with an annular lock groove (6) that matches with slotting (2) plug ends of U-shaped, on tapered end (1), be processed with one and insert hole (7) from locking bolt, can be located at the rear portion (as shown in Figure 2) of former tapered end jack (3) from the position that locking bolt inserts the hole, also can be located at its side (as shown in Figure 3).

Claims

1, the utility model relates to a kind of slotting formula Vehicle lock with duplex auto-lock function, it comprises tapered end (1) and slotting (2) composition of U-shaped, it is characterized in that: on tapered end (1), be connected with a chain (4), the chain front end is one from locking bolt (5), from the diameter of locking bolt (5) less than tapered end on jack (3) aperture, on locking bolt (5), be processed with one and insert the annular lock groove (6) that plug ends is matched with U-shaped.
