Abstract

The utility model relates to a novel double safety anti-theft lock for vehicles, which is characterized in that both sides of a lock body are respectively provided with a hole in which a lock rod and a lock chain rod can be inserted; when a lock core is turned by a key, the lock rod and the lock chain rod can be unlocked simultaneously. A vehicle with the utility model not only can be locked, but also can be connected with fixing objects or trees around the parking position through a lock chain, thereby, the prying and removal of the vehicle by stealers can be effectively avoided. The utility model is an ideal substitute for an anti-theft lock for vehicles at present.

Description

A kind of new vehicle dual-safety anti-theft lock

The utility model relates to theftproof lock, particularly a kind of structure that prevents a kind of theftproof lock that the stolen two sides of vehicle can be locked.

In recent years, bicycle, the stolen phenomenon of motorcycle happen occasionally, cause damage for the car owner economically, although various theftproof locks constantly come into the market, but still fail effectively to prevent that bicycle, motorcycle are stolen, trace it to its cause, the various theftproof lock theftproof performances that mainly are use at present are poor, joyriding more is that the vehicle that will steal moves storage place, or transports to other places with other vehicle, makes the car owner hard to guard against.

Task of the present utility model is: design a kind of dual-safety anti-theft lock that can lock together with fixture or many vehicles, make joyriding hope car heave a sigh, have no way of doing it, and increased tamper-resistant function, prevented that effectively vehicle is stolen.

The technical solution of the utility model is: this theftproof lock connects the ring lock body by lock body and forms, there is the hole for lock car bar and the insertion of chain bar the lock body both sides, lock core is that the two sides is all with a cylinder of rib, locking Xiao and rib are joined platform, by the key rotary locking cylinder locking bar on both sides and chain bar are opened simultaneously, simultaneously on the chain bar, be connected with chain, the terminal available chain of chain circle that connects of chain passes metal ring and any fixed object bolt jail, outside vehicle not only self being locked to steal, and because the effect of chain, make the burglar can't moving vehicle, guarantee vehicle fully.

Fig. 2 is a lock core internal construction schematic diagram

Fig. 3 is the lock core schematic diagram

Further introduce technology contents of the present utility model and implementation method below in conjunction with accompanying drawing:

Lock body shell 1 firmly is connected with ring lock body 12, there is the hole 2,3 for

lock car bar

5 and 6 insertions of chain bar the lock body both sides, lock cylinder 4 both sides all with outstanding rib 9, locking Xiao 7,8 under the promotion of limit spring 13, to lock car bar 5 and chain bar 6 card jails, the groove 14 that rib 9 when clockwise rotating lock core 4 with key on the lock core promotes on locking Xiao withdraws from Xiao 7,8 from the tongue-and-groove 15 of

bar

5,6, lock car bar 5 and chain bar 6 just can eject from the hole 2,3 of lock body both sides, chain bar 6 is connected with metallic bond 10, and the metallic bond end has metal ring 11.

During use ring lock body 12 and vehicle are fitted together, chain can carry with car.When the car owner is stopped, after earlier locking bar 5 being passed rim and inserting lockhole 2 lockings, again with chain 10 around one weeks of fixture such as railing, electric pole, companion's vehicle or trees, pass chain circle 11 with chain bar 6, again bar 6 is inserted lockholes 3 lock jails, get final product relieved leaving.Auto theft person both can't picking lock, also can't move, and had guaranteed the safety of parking of vehicle.

The utility model not only can be used for locking bicycle, motorcycle, can also be used to locking various vehicles such as buggy, flat car, tricycle, is the desirable replacement product of present theftproof lock, has excellent popularization to be worth.
