Abstract

The invention discloses an antitheft device for an automobile tire and an installing and disassembling method thereof. The antitheft device comprises an antitheft bolt and a special sleeve acting on the antitheft bolt; the antitheft 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 round bolt head part; the other ends of the three grooves extend along the radius direction of the round bolt head part; the special sleeve comprises a sleeve head part and a sleeve tail part; the sleeve head part comprises three bosses matched with the three grooves; the section of the sleeve tail part is of a regular quadrangle or regular hexagon shape. According to the antitheft device for the automobile tire and the installing and disassembling method thereof, when the antitheft bolt needs to be installed and disassembled, only the special sleeve needs to be sleeved on the antitheft bolt and a universal screw wrench in a tool box is used for sleeving the tail part of the special sleeve to rotate; the bolt head part of the antitheft bolt is of a cylinder shape, and thus, the common wrench has no acting point, so that the antitheft device takes an antitheft effect.

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...
