Abstract

The utility model discloses a theft-proof chain of a chain lock, which is formed by that a series of special tubular steel chain rings 2 are connected in series and piled by a steel rope 1, two adjacent tubular steel chain rings 2 are separated with a distance by a rope clip 3, and the rope clips 3 and the steel rope 1 are fastened by pins 4. As the steel rope 1 is not exposed, the steel rope 1 is not easy to cut. The theft-proof chain of a chain lock has simple structure and is safe and convenient to realize.

Description

Theft-proof chain of chain lock

The utility model relates to the chain of antitheft blockchain lock such as bicycle, motorcycle, and it belongs to the B62H5/00 class.

In the prior art, steel wire lock steel wire commonly used is thinner, is cut off easily, does not have antitheft effect, if use thicker steel wire, though can improve shear strength, crooked degree is restricted, uses inconvenient.

In patent documentation WO83/00354 chain lock and security system (Chain lock and storagc system), propose employing chain link and chain link and buckled connection ground chain mutually.Because of outside chain link is exposed to, also there is the possibility of easily being cut off.

The purpose of this utility model provides a kind of chain of antitheft blockchain lock, and it can not be cut off easily by the people, can accomplish random bending again, satisfies the needs of safety lock car.

For reaching above-mentioned purpose, the utility model employing is a kind of can make antitheft blockchain chain with wire rope arbitrarily agley, and by a series of through quenching and surfacing ground tubular steel chain link, gather into folds with wire rope series connection cover, between every adjacent two tubular steel chain links, spaced apart them with wire clips, wire clips and wire rope are fastening by pin.

The tubular steel chain link will quench and surfacing, makes it have higher hardness, is difficult for cutting off and corrosion.

The utility model has the advantages that: (1) thinner wire rope is protected in the tubular steel chain link, outside not being exposed to, has just prevented to be cut off, with the comparison of general blockchain chain, safety factor height.(2) simple, the realization easily of this chain structure.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

Among the figure: 1 wire rope, 2 crooked shape tubular steel chain links, 2a tapered tubular steel chain ring, 3 ball-type wire clips, 3a cast wire clips, 4 pins, the plug of 5 chain ends, the wire rope handling tube of 6 chain ends, 7 rope guarding plates, 8 coded lock chains, 9 dead bolts, the 10th, lock body, 11 padlock chains, 12 padlocks, 13 padlock chain wire rope handling tubes, 14 right snap closes, 15 bolts, 16 left snap closes.

By Fig. 1,2 as can be known, the utility model by crooked shape tubular steel chain link 2 or tapered tubular steel chain ring 2a and ball-type wire line shoe 3 or cast wire clips 3a(referring to Fig. 3,4) and pin 4 form.

Embodiment 1, Fig. 5 are in bicycle, the motorcycle anti-theft crypto van chain lock, adopt the operating principle and the structural representation of the utility model chain 8.This chain 8 is made up of wire rope 1, crooked shape tubular steel chain link 2, ball-type wire clips 3 and pin 4.By wire rope 1 a series of swan-neck shaped steel chain link 2 series connection and cover are gathered into folds, it is spaced apart between the per two adjacent swan-neck shaped steel chain links 2 with ball-type wire clips 3, can crooked separately and rotation by pin 4 with wire rope 1 and wire clips 3 fix tightlies, each crooked shape tubular steel chain link 2 of being connected, thus arbitrarily bendings of chain 8 guaranteed.

One end of chain 8 is by wire rope 1, wire clips 3 and pin 4 are packed in the coded lock 10, other end wire rope 1 by two lacing holes (referring to Fig. 7) on the wire rope handling tube 6 by rope guarding plate 7, by tightening plug 5(referring to Fig. 6) the thread connection part, compress wire rope 1, plug 5 inserts lock body 10, dead bolt 9 enters and makes lock be in blocking in plug 5 holes, for preventing that turning wire rope handling tube 6 mills a breach at the tube of wire rope handling shown in Fig. 7 edge, and it is equipped to leave chain and this breach of projection at the patchhole of lock body 10.

Embodiment 2, and Fig. 8 is operating principle and the structural representation that adopts the utility model chain 11 in bicycle, the motorcycle anti-theft chaining lock.This chain 11 is made up of wire rope 1, tapered tubular steel chain ring 2a, cast wire clips 3a and pin 4.By wire rope 1, a series of conical pipe steel chain ring 2a series connection and cover are gathered into folds, 3a is spaced apart with it with the cast wire clips.By pin 4 with wire rope 1 and wire clips 3a fix tightly.Each the tapered tubular steel chain ring 2a that is connected guarantees that chain 11 is arbitrarily crooked.

The two ends of chain 11, adopt structure identical about two snap closes 16 and 14.And two snap closes 16 and 14 bonnet lock hole and locking about passing with the dead bolt of padlock 12.About two snap closes as shown in figure 11.By screw 15 with right snap close 14 compress wire rope 1, wire rope 1 is the termination of chain 12, it is to inject in 13 liang of holes of padlock chain wire rope handling pipe referring to Figure 10, be right snap close 14 and threading tube 13 to be compressed the termination of wire rope 1 as shown in Figure 8 by tightening screw 15, because of two ends, chain left and right sides connecting mode is identical, left end is no longer narrated.

Claims (3)

1, a kind of antitheft blockchain chain, it is characterized in that: by a series of through quenching and surfacing ground tubular steel chain link 2 usefulness wire rope, 1 series connection and overlapping gathers into folds, between every adjacent two tubular steel chain links 2, spaced apart them with wire clips 3, wire clips 3 and wire rope 1 are fastening by pin 4.

2, antitheft blockchain chain according to claim 1 is characterized in that: tubular steel chain link 2 is swan-neck or conical tube shape.
