Description

Earth-pile type lock for bicycle or motor cycle

The utility model relates to a kind of bicycle, motorcycle ground pile lock, is fit to be fixedly mounted on ground or the wall, pins the wheel of various vehicles.

As everyone knows, the lockset that existing bicycle, motorcycle are equipped with is mounted on the car, and when outdoor, can play certain antitheft effect with lock daytime.But exist weak point to be: the stolen of vehicle usually is to occur in night, and the robber utilizes the shielding of the curtain of night, pulls away or shift onto remote place with being parked in outdoor vehicle, lock destroyed again; Perhaps simply bicycle, motorcycle are placed on tricycle or the motor vehicle and steal.When the car owner wakes up from a sleep, in the time of going out by bike, find that car has disappeared suddenly, this is the angry thing that people often run into.

The purpose of this utility model is for overcoming a kind of ground pile lock that bicycle, motorcycle can be connected with ground or wall that above-mentioned weak point provides.

Characteristics of the present utility model are by bolt, base plate, ground pile lock are fixed on ground or the wall, and after wheel pushed, stop pinned wheel.Its operating principle is: when car was pressed on the top of two-sided tooth bar, two-sided tooth bar sank, and drove the left and right stop upwards upset simultaneously with its both sides engagement, and in the middle of wheel was closed in, two-sided tooth bar waist was drilled with two radial holes.Rotate key by hand, make shift fork promote locking bolt and plug the hole, with two-sided tooth bar location, left and right stop is also located thereupon, and wheel can't withdraw from, thereby reaches anti-purpose of removing the robber.

The utlity model has rational in infrastructure, firm, easy to use laborsaving, advantage that theftproof performance is good is installed.Can be fixed on ground or the wall, be fit to pin the wheel of various vehicles.

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