Description

Lock is assisted theft-prevention structure

Technical field

The utility model is the ring-like lockset that makes bicycle, and except having the locking vehicle, having more can be chain in the object of external environment, lifts the effect of stealing and must take precautions against by whole.

Background technology

The lockset of bicycle, nothing more than having: the V-type rod-type, cable type, ring-like latched, U type rod-type, cable type all is separated with car body, the Shi Zaiyu that locks passes vehicle and locks, and need repeat the inconvenient problem of the use of inserting, detaching so have.And ring-like latched, structure as shown in Figure 1, it is the ring lock 10 of a ring-type, housing 11,12 by two double seam constitutes, and for being locked in car body, is equiped with the lock bolt 14 of annular in it, its side is provided with chute 13, be interspersed with for the driving lever 15 with lock bolt 14 welding one, 15 of driving levers can cooperate locking, unblanking of key 16, pass vehicle or do not pass vehicle and stir lock bolt 14; Above-mentioned, ring lock has following shortcoming in fact: though can be assembled into one with car body, and vehicle is locked, but can not link one (for example railing, another bicycle) with the object of external environment and link one, and a bicycle can be born away easily, so, though its lock still have by whole lift steal situation take place.

Summary of the invention

The purpose of this utility model is: the housing of ring lock, driving lever, be respectively equipped with sleeve, fastening sheet and the sandwich sheet of one, and establish one have plug together the head, the fastening groove cable wire, when locking state, cable wire plugs together in the driving lever sleeve, unless and be stuck to be to break away from and unblank and can break away from, so, the lock bolt lockable vehicle of ring lock, but then sleeve is in cylinder or another bicycle of external environment for cable wire, and reaching can not be by whole the antitheft effect of bearing away.

The technical solution of the utility model is: a ring lock 20, combine by two double housings 21,22, and be provided with slidably annular lock bolt 24 in it, its side is provided with chute 23 and passes for the driving lever 25 with lock bolt 24 welding one; These driving lever 25 outer ends, the sleeve 26 that is provided with one must plug together binding for a cable wire 30, and its sleeve 26 is provided with profile groove 28 and is formed with fastening sheet 27; The bottom of these housing 21 chutes 23, the lug that is provided with one give establish clamp slot 211 and be formed with the folder stator 210; These cable wire 30 terminations are provided with and plug together 31, plug together 31 and be provided with annular fastening groove 32, must plug together in 31 insertion driving levers, 25 sleeve 26, and just its fastening groove 32 corresponding to the profile groove 28 of sleeve 26, and, when locking, driving lever 25 sleeves 26 dialled turn to against, be positioned chute 23 bottoms, formation clamp slot 211 sandwiches cable wire 30 fastening grooves 32, folder stator 210 inserts in sleeves 26 profile grooves 28, is and can not breaks away from sleeve 26 binding one and get cable wire 30.

The specific embodiment

When desiring to lock together with cable wire 30, cable wire 30 can be overlapped the cylinder (railing) that locks in external environment in advance, or on the bicycle of another acquaintance car (shown in figure four A), again with 31 sleeves 26 that insert ring locks 20 driving levers 25 that plug together of cable wire 30, plug together 31 fastening grooves, 32 a proper profile groove 28 corresponding to sleeve 26, at this moment, can stir driving lever 25 downwards, lock bolt 24, make lock bolt 24 pass vehicle, sleeve 26 plugs together 31 and the passive intermediate plate 210 of accomplishing the bottom together with cable wire 30, the 211 proper clampings of folder stator 210 clamp slots plug together 31 a fastening groove 32, folder stator 210 just inserts sleeve 26 profile grooves 28, also be the position of locking and locking this moment, be drawable key 16 and lock bolt 24, sleeve 26 is locked, so cable wire 30 promptly links one with ring lock 20 sleeves 26 and can not break away from.

In other words, when locking state, driving lever 25 sleeves 26 are locked folder stator 210 places that are resisted against the bottom, and be that folder stator 210 folder (inserting) closes cable wire 30 and plugs together 31 a fastening groove 32 and plug together in sleeve 26 profile grooves 28, therefore, be and plug together 31 with cable wire and link and be closed, can not be detached again so can make cable wire 30 plug together 31, unless allow when unblanking driving lever 25 sleeves 26 upwards action break away from and press from both sides stator 210 and can detach cable wire 30 and plug together 31.

By above-mentioned explanation as can be known, it is not rotatable that ring lock 20 lock bolts 24 of the present utility model can lock vehicle, and cable wire 30 then can be chain in other objects, and reaching bicycle can not be by whole the antitheft effect of bearing away.
