Problems solved by technology

[0004] However, for this combined tire nut, since the axial first end of the movable washer and the nut are interposed together in a detachable manner, the axial second end of the movable washer is socketed together with the washer of the positioning guide sleeve, so that The bonding tightness between the movable washer and the nut and between the movable washer and the washer of the positioning guide sleeve is poor. At the same time, the hollow cylinder gasket will be deformed due to long-term shear force and riveted on the tire screw. When the combined tire nut is disassembled like this, the movable washer cannot drive the hollow cylinder backing ring of the positioning guide sleeve washer to unscrew from the wheel bolt hole, so that the positioning guide sleeve washer is not easy to disassemble from the tire screw rod, so that the replacement of the nut and the screw rod is easy. Inconvenience

Embodiment Construction

[0019] An improved combined tire nut of the present invention, such as figure 1 , 2 As shown, including nut 1, movable washer 2 and positioning guide sleeve washer 3, the nut 1, movable washer 2 and positioning guide sleeve washer 3 are all hollow structures with openings at both ends, and the axial direction of the movable washer 2 is first end and the first axial end of the nut 1 are movably socketed together in a relatively rotatable manner, and the first axial end of the movable washer 2 and the first axial end of the nut 1 are provided to prevent the nut 1 from The movable washer 2 is the first riveting structure that is axially separated. The first riveting structure includes the first riveting section and the first riveting surface for the first riveting section to be riveted together, that is, the axial direction of the nut 1. The first end face is protruded with a hollow annular protruding ring 11 whose outer diameter is greater than the outer diameter of the nut 1, ...

Abstract

The invention discloses an improved combined tire nut for automobile tires, which comprises a nut, a movable washer and a positioning guide sleeve washer. The first riveting structure in which the nut is axially separated from the above-mentioned movable washer, the axial second end of the above-mentioned movable washer and the axial first end of the above-mentioned positioning guide sleeve washer are provided to prevent the above-mentioned movable washer and the above-mentioned positioning guide sleeve washer shaft to the separated second riveting structure.

Description

technical field [0001] The invention relates to parts of a fastener, in particular to an improved combined tire nut for automobile tires. Background technique [0002] Among the fasteners commonly used in automobiles, the bolt assembly in which the nut and the screw are matched is a common and widely used fastener. When the tire bolt assembly fastens the automobile wheel, in order to facilitate the disassembly of the automobile wheel, the diameter of the tire screw of the tire bolt assembly is generally 4-6mm smaller than the diameter of the wheel hub bolt hole. Due to the factor of diameter difference, the wheels form irregular operation when walking, so that the car is prone to generate great shear force on the tire bolt assembly when the car bumps, vibrates and brakes, resulting in damage to the tire bolt assembly. , which shortens the service life of the tire bolt assembly. [0003] In order to reduce the assembly gap between the bolt hole and the tire bolt, there is a...
