Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] see figure 1 , the spare tire rack hook 2 of the spare tire rack hook assembly 3 is formed by bending round steel, the diameter of the bend is slightly larger than the diameter of the spare tire rack 5, and the bending depth is also greater than that of the spare tire rack 5 Diameter, so it can ensure that the assembled spare tire carrier can be accurately and firmly assembled into the hook. The bushing 1 is tapped from a round steel pipe, and the full tapping method adopted can ensure the meshing strength and orientation with the spare tire bracket bolt 4. Finally, the two are welded by a welding fixture, and the upper end of the hook 2 is welded On the outside of the sleeve pipe 1, and ensure that the center of the hook part at the lower end of the hook 2 is located on the axis extension line of the sleeve pipe 1.

[0014] see figure 2 , when assembling, p...

Abstract

The invention discloses an automobile spare tire carrier hook assembly, which consists of a hook, a sleeve and a bolt. The upper end of the hook is welded outside the sleeve; the center of a hooked part at the lower end of the hook is positioned on an axis extended line of the sleeve; the width and the depth of the hooked part of the hook are greater than the diameter of a spare tire carrier bracket; the inner bore of the sleeve is a screwed hole; the bolt is connected with the screwed hole of the sleeve through a hole on an automobile body rear plate; and the lower end of the bolt props against the spare tire carrier bracket which is hanged to the hooked part of the hook. A bolt head of the bolt is arranged in a carriage. Compared with the prior art, the automobile spare tire carrier hook assembly can accurately realize assembly positioning and high intensity of the spare tire carrier, and has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to an automobile spare tire rack, in particular to an automobile spare tire rack hook assembly. Background technique [0002] At present, the spare tires of mini-cars are basically arranged under the body floor to maximize the internal space of the car body, but the anti-theft and loosening of the spare tire brought by this arrangement has become a major problem. [0003] At present, as the main part of the spare tire fastening and anti-loosening and anti-theft-the spare tire rack hook assembly is welded by stamped steel sheets and hexagonal nuts, but due to poor control of stamping and welding positioning, resulting in The spare tire rack hook cannot fix the spare tire rack bracket well, and then the spare tire becomes loose and easy to be stolen. Contents of the invention [0004] The purpose of the present invention is to provide a car spare tire rack hook assembly that can easily achieve precise welding positioning and high...
