One head of the steel wire rope has a locking head which can lock up the steel wire rope. A pair of hollow expansion bolt and an expansion screw nut are sleeved on the steel wire rope. A stop block is fixed on the other head of the steel wire rope in order to protect the hollow expansion bolt and the expansion screw nut against shedding from the steel wire rope. When people ride bicycles, the lock is sent into the tube after installing the lock. When people lock bicycles, the locking head is pulled from the vehicle tube. The lock has the advantages of common steel wire rope lock, and the lock also has convenient unlocking and locking such as a ring lock for bicycle.

Description

Be contained in the bicycle wire rope lock in the pipe

The utility model relates to a kind of improved bicycle wire rope lock, particularly a kind ofly can be contained in get off Steel wire rope lock in the back rest pipe of bicycle handle bar or vehicle seat.

Existing bicycle lock adopts ring type lock, rope chain lock and Steel wire rope lock, though the ring type lock is locked car, the convenience of unblanking, is easily pried open, and is dangerous, can only pin wheel itself; Rope chain lock and Steel wire rope lock can lock together wheel and fixture, and be safe and reliable.But carry inconvenience in the time of by bike, not as ring type is locked easy to use.

The utility model provides a kind of improved Steel wire rope lock, and it had both had the advantage of general Steel wire rope lock, can be contained on the bicycle again.Resemble and lock car the ring type lock, unblank conveniently.

Task of the present utility model is finished as follows: this Steel wire rope lock that is contained in the pipe, one has the tapered end that can overlap the wire rope of pinning own on its wire rope, on wire rope, be with one pair of hollow expansion bolt and expansion nut, be fixed with a block on the other end of wire rope and prevent that hollow expansion bolt and expansion nut from coming off from wire rope.Block, hollow expansion bolt and expansion nut are can adorn person bicycle in the pipe or in the car back rest pipe under the vehicle seat, and expansion nut can make expansion nut expand after expansion bolt screws in, and stuck in handlebar or car beam pipe.After bicycle is loaded onto this lock, in the time of by bike lock is sent in the pipe; During the lock car tapered end is pulled out from the car pipe, expansion nut has been fixed stuck in the car pipe, block is inflated nut and blocks, wire rope can not be thrown off with the car pipe, wire rope is walked around fixture, the tapered end cover pins wire rope itself and gets final product, and this lock had both had the advantage of general Steel wire rope lock, can be contained on the bicycle again.Resemble and lock car the ring type lock, unblank conveniently.

Describe in detail below in conjunction with accompanying drawing and the embodiment that provides.

Fig. 1 is the structural representation of the embodiment that provides of the utility model.

Fig. 2 is that this lock is contained in the assembling drawing in the handlebar tube.

Fig. 3 is that this lock is contained in the assembling drawing in the vehicle seat back rest pipe.

User mode schematic diagram when Fig. 4 locks car for this lock is a kind of.

This lock is at wire rope 3, be fixed with a tapered end 2, its lock ring 1 can the wire rope 3 of pinning own, on wire rope 3, be with one pair of expansion bolt 4 and expansion nut 5, one block 6 is arranged in the other end of wire rope 3, by jackscrew 7 that block 6 is fixing, it is spherical that block 6 is preferably, when being installed in this lock on the bicycle, the mouth of the plastics grip 9 of bicycle handlebar is opened big, block 6 is pierced into (see figure 3) in the pipe of the car back rest 10 under (see figure 2) in the pipe of handlebar 8 or the vehicle seat 11, the hollow expansion bolt 4 and the expansion nut 5 that are enclosed within on the wire rope 3 are also sent in its pipe, use special rotating tool, expansion bolt 4 is screwed in the expansion nut 5, and because of expansion bolt 4 has certain taper, expansion nut 5 has cross recess, nut 5 is expanded, so just expansion nut is fixed in the pipe of the handlebar 8 or the car back rest 18, for increasing fastness, when mounted, be used adhesive, make it to be securely fixed in the car pipe.When not locking car, lock is sent in the car pipe, during the lock car, tapered end 2 is gone out from car pipe lira, and expansion nut 5 has been fixed in the car pipe, and block 6 is blocked by nut 5, wire rope 3 can not deviate from from the car pipe, and the tapered end 2 of wire rope 3 is walked around fixture 12 like this, and its lock ring 1 pins wire rope itself.(see figure 4)

Claims

1, a kind of bicycle wire rope lock that is contained in the pipe, on its wire rope 3, one has the tapered end 2 that can overlap the wire rope 3 of pinning own, it is characterized by: on wire rope 3, be with one pair of hollow expansion bolt 4 and expansion nut 5, fix one on the other end of wire rope and prevent the block 6 that hollow expansion bolt 4 and expansion nut 5 come off from wire rope 3.
