Description

A kind ofly be arranged at the quick detachable lock of lockset on vertical tube of front fork to loop device

Technical field

The utility model relates to technical field of bicycles, specifically, it be a kind of for the quick detachable lock on vertical tube of front fork to loop device.

Background technology

Stolen for preventing bicycle in prior art, generally anti-theft column lock can be installed on bicycle head tube.This kind of anti-theft column lock arranges through hole on vertical tube of front fork, and the dead bolt by anti-theft column lock inserts or exits in through hole, realizes bicycle unlocking or release, and then reaches the purpose of bicycle theft-prevention.Then after dead bolt inserts through hole and realizes locking, as while the mechanism of anti-theft column lock inside or circuit board damage or other problem occurring, need it is keeped in repair.But those mechanisms or circuit card are installed on the inside cavity of anti-theft column lock, and, because security needs can be fixed it by bolt in head tube inside, therefore the dead bolt of anti-theft column lock need to be taken off from the through hole of vertical tube of front fork, can be keeped in repair.Obviously above-mentioned structure design, due to the defect self existed, can not take off the anti-theft column lock dead bolt from the vertical tube of front fork through hole, and maintenance is trouble and inconvenience comparatively.

Therefore, prior art awaits improving and improving.

Summary of the invention

For the deficiencies in the prior art part, the purpose of this utility model is by a kind of quick detachable lock of lockset on vertical tube of front fork structure design to loop device that is arranged at, make anti-theft column lock of the prior art have when breaking down and be easy to pull down, be convenient to the characteristics of maintenance.

For achieving the above object, the technical scheme that the utility model adopts is: a kind ofly be arranged at the quick detachable lock of lockset on vertical tube of front fork to loop device, comprise back-up ring on chain pin, lock ring and lock ring, described chain pin is close on the outer wall of vertical tube of front fork along the vertical tube of front fork axis direction, and has and be partially submerged into it in suitable vertical tube of front fork through hole; Described chain pin and vertical tube of front fork are equipped with suitable with it lock ring outward, and the inside of this lock ring is provided with an inner groovy coordinated with chain pin, and the outer surface of this lock ring is provided with at least one outer groove, and wherein the upper and lower of chain pin is exposed to outside lock ring; The outer face of described chain pin bottom is greater than the distance of lock ring and chain pin abutted surface along the vertical tube of front fork radial distance; The top of described lock ring also is provided with back-up ring on a lock ring be placed on vertical tube of front fork, and on this lock ring, an end of back-up ring is inserted in the upper manhole on chain pin top under the effect of elastic force.

Preferably, on described lock ring, back-up ring is provided with a V-type bending groove near place, chain pin top, and upper back-up ring is that the jump ring one end that a diameter is less than the vertical tube of front fork diameter is inserted in the manhole on chain pin top.

Preferably, the below of described lock ring also is provided with back-up ring under a lock ring be placed on vertical tube of front fork, and this time back-up ring is the jump ring that a diameter is less than vertical tube of front fork, and the one end is inserted in the manhole of chain pin bottom.

Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structure design, lock ring with matching and chain pin are installed on existing vertical tube of front fork, and back-up ring on the lock ring of lock ring top, thereby are realized quick detachable, the purpose of being convenient to maintenance of lockset.

The utility model is simple in structure, reasonable in design, has convenient disassembly, keeps in repair the characteristics such as easy.

The accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model;

The A-A cutaway view that accompanying drawing 2 is accompanying drawing 1;

The B-B cutaway view that accompanying drawing 3 is accompanying drawing 1.

In figure, each label respectively: (1) vertical tube of front fork, (2) chain pin, (3) lock ring, back-up ring on (4) lock ring, (5) bending groove, back-up ring under (6) lock ring, (7) inner groovy, (8) outer groove.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1-3, the utility model is a kind of is arranged at the quick detachable lock of lockset on vertical tube of front fork to loop device, comprise back-up ring 4 on chain pin 2, lock ring 3 and lock ring, described chain pin 2 is close on the outer wall of vertical tube of front fork 1 along the vertical tube of front fork axis direction, and has and be partially submerged into it in suitable vertical tube of front fork through hole; The outer suitable with it lock ring 3 that is equipped with of described chain pin 2 and vertical tube of front fork 1, the inboard of this lock ring is provided with an inner groovy 7 matched with chain pin 2, and this inner groovy and chain pin 2 coordinate can not rotate and move the ad-hoc location that lock ring 3 is fixed in vertical tube of front fork; The outer surface of this lock ring also is provided with at least one outer groove 8, and this groove matches for locked direction with dead bolt.Wherein the upper and lower of chain pin 2 is exposed to outside lock ring 3; The outer face of described chain pin 2 bottoms is greater than the distance of lock ring 3 and chain pin 2 abutted surfaces along the vertical tube of front fork radial distance; Lock ring 3 can not be deviate from from the bottom of chain pin 2.The top of described lock ring 2 also is provided with back-up ring 4 on a lock ring be placed on vertical tube of front fork, on this lock ring, an end of back-up ring 4 is inserted in the upper manhole on chain pin 2 tops, by above-mentioned structure design, under normal circumstances, effect due to back-up ring on lock ring 4, prevent that lock ring 3 from moving up, make groove on lock ring 3 match with dead bolt to realize and open or the basic function of locking; After lock ring 3 and dead bolt locking, during as anti-theft column lock et out of order or damage, by a bar shape, back-up ring on lock ring 4 is exited in manhole from chain pin 2, lock ring 3 can be exited from the top of chain pin 2.Can make vertical tube of front fork 1 break away from from the head tube of bicycle, and then just can be keeped in repair anti-theft column lock after removing bolt.
