Abstract

The utility model relates to a rolling chain lock which is composed of a casing, a rolling spring, a chain and a lock and used for cycles, leather bags and boxes to prevent objects from being stolen. The center of the casing is provided with a fixed axis, the rolling spring is fixedly connected between the fixed axis and a sleeve barrel, the chain is winded out of the sleeve barrel, the other end of the chain exposes out of the casing and is fixedly connected with the lock, the lock and the casing are connected by the telescopic chain, and objects are locked to fixed objects, such as trains, luggage carriers or trunks by the lock and the casing. The utility model has the advantages of novel structure, convenient portability, convenient use and high safety, and the rolling chain lock can be used for replacing the existing padlocks, keylocks and chain locks.

Description

Rolling chain lock

The utility model relates to a kind of metal material that adopts and constitutes the Rolling chain lock that can be used for things such as bicycle, suitcase are locked in fixed object through what machining process was manufactured by parts such as housing, fixed axis, coil spring, chain, block card and handcuffs locks.

Lockset is a kind of safeties, at present institute's use lockset mainly contain padlock, by lock and chain lock etc., these locks can pin locked object itself, can lock a door as padlock, coded lock can pin strongbox (cabinet), can lock its cabinet by lock, chain lock can be locked bicycle and suitcase, although padlock, coded lock and can lock thing by lock can not lock together locked object and other fixtures, in case locked object is stolen.Chain lock can lock together locked object and fixed object, but uses and carry very inconveniently, because its chain limited length, makes the effect of only playing under many situations by lock when being particularly useful for bicycle, is also connected bicycle by the people easily and steals and push away away.So end is got up, existing lockset exists and is not easy to carry, use not nimble and by shortcomings such as the lock distance can not change.

Goal of the invention of the present utility model is to overcome the shortcoming that existing lockset exists, and a kind of novel structure of design and manufacture, easy, easy to use, flexible is locked distance variable, and the portable novel Rolling chain lock of lockset itself.

In order to realize the foregoing invention purpose, agent structure of the present utility model is divided into housing, chain (or flat wire rope) and handcuffs lock three parts.The housing center is shaped on fixed axis, and coil spring one end and fixed axis are connected, and the other end and sleeve are connected, and the fixed axis both ends are milled with the plane, and sleeve is placed on fixed axis and the coil spring.It is outer and connect with the handcuffs locking that the sleeve outside chain that is connected, and being wrapped on the sleeve, the other end of chain are exposed at housing.Housing is generally circular or square, and the outside should be attractive in appearance smooth, generally makes with the high-test metal material, to guarantee enough intensity being arranged and carry nimble property; Chain can be selected snap ring type or woven for use, and its length is generally 60～120cm.Chain also can be selected flat-shaped wire rope for use.Housing upper end one side is shaped on block card, after chain is pulled out certain-length, it is bottled up in case the elastic force influence of coil spring is exposed at the nimble property of the outer chain of housing by block card.Housing upper end opposite side is shaped on flange and is shaped on the hole on flange, so that be connected with the locked object body.Chain adopts bearing pin to be connected with the handcuffs lock, steals locked object in case the quilt sled is bad.The handcuffs lock generally selects for use the public security of deciding circle and moving-coil two parts formation to split handcuffs lock form with annular, also can select coded lock for use.

The utility model compared with prior art has novel structure, and is easy to use and carry, locked outstanding advantages such as distance variable, and applied range, especially more nimble in carrying the road to valuables such as bicycle, leather bagboxs.

Fig. 1 is an agent structure schematic diagram of the present utility model.

Enforcement of the present utility model adopts metal material to manufacture through the machining mode, mainly contains parts such as housing 1, sleeve 2, coil spring 3, fixed axis 4, block card 7, chain 8, handcuffs lock 9 and constitutes.Housing 1 center is shaped on fixed axis 4, and coil spring 3 is wrapped in two ends and is milled with 5～8 circles on the fixed axis 4 on plane, and its outside is shaped on sleeve 2, and coil spring 3 two ends are connected with screw 5 and rivet 6 and fixed axis 4 and sleeve 2 respectively.Sleeve 2 outsides are with rivet 11 chain 8 that is connected, and are wrapped in 5～8 circles on the sleeve, and it is outer and connect with the handcuffs locking that the other end of chain exposes housing by the outlet on the housing 1 13.Housing 1 outside should be attractive in appearance smooth, generally make with the high-test metal material, to guarantee enough intensity being arranged and carry nimble property, its appearance and size depends on the size of inner part, is generally long 50～80mm, wide 50～120mm, thickness 25～40mm, housing 1 upper end one side is shaped on block card 7 with rivet 10, after chain 8 is pulled out certain-length, it is bottled up in case the nimble property of the outer chain of housing is exposed in the elastic force influence of coil spring 3 by block card 7; Housing 1 upper end opposite side is shaped on flange 14 and is shaped on fixing hole 16 in its moderate position, so that be connected with the locked object body and hand; Block card 7 has a rotational angle by rivet 10 on housing 1, so that chain 8 is flexible.Chain 8 adopts bearing pin to be connected with the handcuffs lock, and to guarantee to allow its fixing and degree of safety, the total length of chain is generally 60～120cm, can select snap ring type or woven for use.Handcuffs lock select for use by enclose surely 12 and the public security formed of moving-coil 15 split with annular and put handcuffs on the lock form and also can adopt coded lock.

When the utility model uses as long as lie in fixing hole 16 in the hand or be formed on the locked object (as bicycle, leather bagbox etc.), put handcuffs on fixed object (as train luggage rack etc.) with handcuffs lock, can guarantee safety, the time spent is not regulated block card by in the chain retraction housing, very convenient to carry, also fixing hole 16 can be made the belt fastener form so that tie up on the waistband, also can utilize screw, rivet or sicker that housing 1 is fixing at the bag or the inboard of case, the handcuffs lock draws and is exposed at bag or case makes bag or case have dual safety effect outward.

Housing of the present utility model and internal construction thereof also can replace with buckle or metal ring, and just chain does not have retractility.
