Abstract

The utility model discloses a device fixed on a tripod of a bicycle, which can tightly lock a shaking head of the bicycle. An upper and a below positioning rings are arranged inside a hollow steel tube of the tripod on the bicycle. A lock core is arranged on the center of the positioning ring; the lock core is matched to the positioning ring and is provided with a rack at the tail part of the lock core. The head end of the lock core extends to the center of a shaking head axis on the bicycle; the rack on the tail part of the lock core is matched with a gear wheel; the gear wheel is arranged inside a locking organ; the locking organ is welded and fixed on the outer surface of the steel tube on the tripod. When in use, the lock core inserted into the shaking head axis can be extracted only needing starting up the locking organ; and then the bicycle can be used.

Description

Bicycle yaw latching device

Affiliated technical field

The utility model relates to the bicycle that uses in people's daily life, the specifically a kind of device that the yaw of car can be locked on the bicycle tripod that is fixed on.

Background technology

The anti-theft feature of bicycle is each bicycle indispensability.People promptly can buy lock simultaneously after buying bicycle in the market generally speaking, and it is installed in region of interest, so that at least one wheel is pinned, it can't be rotated.Stolen in order to prevent, released various anti-theft column locks in recent years on the market, its point of view mainly is to prevent that lock is damaged and makes bicycle stolen.But make after bicycle is stolen aspect it can't continue to be used, then the someone works hard as yet.

Retrieval according to pertinent datas such as Chinese patents shows, has not yet to see the report with the similar relevant patent of the utility model.

Summary of the invention

In order to overcome the problem that existing bicycle lock still can make bicycle after destroyed, the utility model provides a kind of can cooperate former bicycle lock, adding is installed on the bicycle tripod together, promptly match with the yaw axle, and can pin yaw, the later-model bicycle yaw latching device that makes the bicycle after stolen can't swing yaw and continue to use.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of by bicycle tripod, the bicycle yaw latching device that yaw axle etc. is purchased, it is characterized in that: a bicycle tripod is arranged, upper and lower two nests are installed in the hollow steel pipe of spider, the nest central mounting has the lock core that has tooth bar with the tail end of its running-fit, and the head end of lock core rises up into bicycle yaw axle center; Tooth bar on the lock core tail end and a gear matched, gear are mounted in the lockout mechanism; Lockout mechanism is weldingly fixed on the spider on the hollow steel pipe outside face.Described upper and lower nest is fixed in the spider hollow steel pipe; Its center of described yaw axle is drilled with through hole.As long as the startup lockout mechanism rotates gear and drives tooth bar to be retreated, its head that is deep in the yaw is extracted out during use, the use that bicycle just can be natural.

The beneficial effects of the utility model are, make an issue of in bicycle tripod with on the yaw, can't use after making bicycle stolen, and implementation is all very difficult.The lockout mechanism that is weldingly fixed on simultaneously on the spider hollow steel pipe outside face is only untied mechanism under destructive robber's car situation, and spider is inevitable destroyed like this, and bicycle just can't use.So the utility model can reach the purpose of drafting.

Description of drawings

Fig. 1 is a concrete structure scheme drawing of the present utility model.

Among the figure 1, spider, 2, nest, 3, lock core, 4, the yaw axle, 5, gear, 6, lockout mechanism.

The specific embodiment

A bicycle tripod (1) is arranged among Fig. 1, in the hollow steel pipe of spider (1) upper and lower two nests (2) are housed, the central mounting of nest (2) has the lock core (3) with its running-fit, and the front end of lock core (3) extend into yaw axle (4) center of bicycle: lock core (3) upper end tooth bar cooperates with a gear (5): gear (5) is mounted in the lockout mechanism (6).As long as lockout mechanism (6) is started, just lock core (3) can be detached backward the state that inserts the yaw axle during use, so just can freely use bicycle.

Claims (3)

1. one kind by bicycle tripod, the bicycle yaw latching device that yaw axle etc. constitute, it is characterized in that: a bicycle tripod is arranged, upper and lower two nests are installed in the hollow steel pipe of spider, the nest central mounting has the lock core that has tooth bar with the tail end of its running-fit, and the head end of lock core rises up into bicycle yaw axle center; Tooth bar on the lock core tail end and a gear matched, gear are mounted in the lockout mechanism; Lockout mechanism is weldingly fixed on the spider on the hollow steel pipe outside face.

2. according to the described bicycle yaw of claim 1 latching device, it is characterized in that: described upper and lower nest is fixed in the spider hollow steel pipe.
