Abstract

The invention discloses an anti-theft device and an installation and detachment method thereof. The anti-theft device comprises an anti-theft bolt and a special sleeve tube, wherein the special sleeve tube acts on the anti-theft bolt, the anti-theft bolt comprises a bolt head part and a bolt tail part, the top end of the bolt head part is provided with three grooves, one ends of the three grooves are connected together at the circle center of the bolt head part, the other ends of the three grooves extend in the radius direction of the bolt head part, the special sleeve tube comprises a sleeve tube head part and a sleeve tube tail part, the sleeve tube head part comprises three bosses, the three bosses are matched with the three grooves, and the cross section of the sleeve tube tail part is in a square or hexagon shape. The anti-theft device and the installation and detachment method have the advantages that when the anti-theft bolt needs to be installed and detached, only the special sleeve tube is sheathed on the anti-theft bolt, and a common wrench from vehicular tools sheaths the special sleeve tube tail part and rotates; as the bolt head part of the anti-theft bolt is in the cylinder shape, and the common wrench has no force applying point, so the anti-theft function is realized.

Description

technical field [0001] The invention relates to a fastener and a special tool for assembly and disassembly thereof, in particular to an anti-theft device for automobile tires and its installation and disassembly method. Background technique [0002] Car tires are fixed on the car hub by bolts. At present, most of the bolts used in car tires are standard bolts. The head shape is mostly hexagonal, and the bolt installation tools are also standard parts, so it is easy to Be pulled down, cause tire to be stolen, bring loss to car owner. [0003] In view of the phenomenon that automobile tires are stolen from time to time, especially the phenomenon of stolen tires of medium and high-end cars is rampant day by day. At present, most middle and high-end cars are equipped with anti-theft bolts. The anti-theft principle is to process the shape of the anti-theft bolts into irregular shapes, so that ordinary disassembly tools cannot be removed. Only the special disassembly tools matchi...
