Description

Chain lock

One, technical field

The utility model relates to a kind of lockset, a kind of specifically chain lock that can carry out locking to the chain of chain drive vehicles such as bicycle, vehicle using motor, motorcycle.

Two, background technology

Along with the rhythm of modern humans's work and life is constantly accelerated, trip more and more be unable to do without the vehicles miscellaneous, for most of working clans, mainly is as walking-replacing tool at present with light vehicles such as bicycle, vehicle using motor or motorcycles.Yet, enjoy to the full when the vehicles offer convenience people, also to deposit safety worried for it.Stolen in order to prevent vehicle, people on Lock for vehicle painstakingly, each lockset producer constantly releases the novel anti-theft lockset for the demand that satisfies market, it mainly comprises U-shape lock, Front fork lock, steel cable lock, chain lock etc., in these locksets some are that the wheel to vehicle carries out locking, as U-shape lock, steel cable lock, chain lock, also have plenty of Vehicular turn spare (front fork) is carried out locking, as Front fork lock, but these locksets all have defective in various degree, wherein, inconvenience is not only installed and used to the mounting points that U-shape lock and Front fork lock need be fixed, and owing to be fixed installation, particularly the locking bar of U-shape lock exposes especially, and the picklock that the burglar is adopted has had the point of application, and easily bad lock core of sled is opened lockset; Though use and steel cable lock, chain lock are fixing, make picklock can't have the point of application, exposed wirerope and chain then are its maximum defectives, once locking pliers only being needed the several seconds can cut off wirerope and chain, make lockset lose effect.Current, each producer generally is simple increasing overstriking lockset in order to improve the anti-theft capability of lockset, make lockset heavy more, but the raising of anti-theft effect is limited.

Three, summary of the invention

The purpose of this utility model provides the chain lock that a kind of chain to chain drive vehicles such as bicycle, vehicle using motor or motorcycles carries out locking, this chain lock does not need the mounting points of fixing, and use back lockset and chain to combine together, not only easy to use, and can be in case impact, prevent shearing, anti-drilling and pick-proof.

The objective of the invention is to be achieved through the following technical solutions:

A kind of chain lock, it comprises lock body and has the U-shape lock bar of locking breach, wherein lock body comprises lock housing, lock core, dead bolt, spring and the chute that is used to insert the U-shape lock bar, described lock core is rotating to be arranged in the lock housing, the dead bolt that is used for locking locking breach is arranged on the side of chute, and be connected with lock core elasticity by spring, it is characterized in that: the sectional dimension of U-shape lock bar can insert it in the chain link of chain, and the distance between its bipod is corresponding with the spacing of chain link, and the locking breach on the U-shape lock bar is one group of locking breach can regulating degree of blocking.

Chain lock of the present utility model is not the chain lock of common employing chain as the lockset link, but is used for the chain of employing chain drive vehicles such as bicycle, motorcycle is carried out the lockset of a kind of novelty of locking.When chain is locked, at first the U-shape lock bar is passed the mesopore of chain link plate, then insert again in the chute of lock body, two dead bolts carry out degree of blocking control to one group of a plurality of breach on the U-shape lock bar in the lock body, its tightness is according to the gap position adjustment, the bottom of locking back locking bar directly contacts with chain link like this, and no exposed parts has played the effect of pick-proof.

If be provided with the arc surface that matches with the chain link contact surface in the bottom of U-shape lock bar, then lockset is after locking, and locking bar and chain link contact surface are fitted fully, and lockset and chain are combined together, and be seamless, the anti-shearing.And because this lockset is light and handy, being suspended on does not need on the chain to fixedly mount a little, also can play anti-ly impact, the effect of anti-drilling, pick-proof.When needs are unblanked, use the key rotary locking cylinder to drive the dead bolt retraction, at this moment in short supply mouthful of dead bolt release lock lever lock, is pulled out locking bar and can be opened lockset.

Compared with prior art, the utility model has the advantages that: (1) is used for the chain of locking chain drive vehicles, modern design; (2) owing to the mounting points that does not need to fix, easy to install and use; (3) act on the movable chain, make picklock not have the point of application, thereby anti-ly impact, anti-drilling, pick-proof; (4) lockset and chain are combined together, prevented shearing; (5) part is few, cost is low, simple to operate, dependable performance.
