A new triple anti-theft bolt wheel lock and its special key for automobiles

Abstract

The invention discloses a novel triple burglarproof bolt wheel lock for an automobile. The novel triple burglarproof bolt wheel lock comprises a bolt body, an inner burglarproof cover and an outer burglarproof cover, wherein a bolt head of the bolt body is of a circular truncated cone structure; a first female die cavity of which the outline is irregular is concavely arranged on the top surface of the bolt head; the inner burglarproof cover is adaptively screwed on the bolt body; a second female die cavity of which the outline is irregular is concavely arranged on the outer side surface of the inner burglarproof cover; the outer burglarproof cover is of a circular truncated cone structure and is adaptively screwed on the bolt head; a third female die cavity with an irregular convex structural body is formed on the outer side surface of the outer burglarproof cover; in the special key for the bolt wheel lock, a first cylindrical head, a second cylindrical head and a third cylindrical head are respectively arranged at three free ends of a T-shaped connecting rod; a first male die block and a second male die block which are matched with the first female die cavity and the second female die cavity respectively are respectively and convexly arranged at the end parts of the first cylindrical head and the second cylindrical head; and a third male die block matched with the irregular convex structural body is arranged at the end part of the third cylindrical head. The novel triple burglarproof bolt wheel lock has a simple structure and favorable burglarproof effect and can be matched with various vehicles and other suitably-assembled mechanical parts.

Description

technical field [0001] The invention relates to an anti-theft bolt wheel lock, in particular to a novel triple anti-theft bolt wheel lock for automobiles and a special key for unlocking the triple anti-theft bolt wheel lock. Background technique [0002] In the prior art, automobile tires are generally locked on the wheel shaft with hexagonal screws. The hexagonal screws have two types: inner hexagonal and outer hexagonal. Tire can be unloaded, though it brings convenience for changing tire, but this also provides the convenience of stealing to the thief, thus often occurs the phenomenon that tire is stolen. [0003] Aiming at the above-mentioned problem of tire being stolen, various bolt-type anti-theft wheel lock devices have also appeared on the market, which either have a complicated structure and cannot be matched with various automobile wheel axles, making it inconvenient to popularize and use; Single anti-theft effect, anti-theft effect is not good; therefore the car...
