The utility model can effectively protect nuts which are exposed of existing automobile tires to make the screw and the junction part not etched by the sandstone and the earth water.
Description
The utility model belongs to a kind of automotive tyre nut protective cover.
It is fastening that now motor tire adopts inside and outside nut mostly, and promptly with the fixing tyre steel ring of inner nut, outer nut is fixed outer tyre steel ring.Owing to there is not protective device, in car running process, be exposed to outer threaded portion and endure the impact of sandstone and the erosion of muddy water to the fullest extent, make these positions that corrosion even distortion take place soon.When need are changed remove a tyre, often outer nut can not be pulled down separately, relax one's efforts and cause outer nut to drive inner nut, all be trapped on the outer rim from the tire bolt back-out together, give to reinstall and bring very big difficulty.The general method of handling is that this inside and outside nut is taken off with destructive method, uses new inside and outside nut more in addition instead.Like this, not only required great effort but also inconvenient and wasted original also reusable part, this automobilist and repairman had been felt very troublesome.
The purpose of this utility model is to provide a kind of influence that can protect lug nut not to be subjected to road conditions and external environment; can easily pull down smoothly after in a single day outer nut is unscrewed and do not influence inner nut, be convenient to nut dismounting and nonexpondable automotive tyre nut protective cover.
The purpose of this utility model is achieved in that a kind of automotive tyre nut protective cover, mainly is made up of cover body and cover cap.
Above-mentioned cover body can be made cross-sectional plane and be hollow hexagon, and the cover cap cross-sectional plane is annular arrangement; Also can make the outer form line of cover body and be hexagon, interior form line is rounded, at the internal operation of cover body connecting thread is arranged; Cover body and cover cap are of similar shape and size.
For prevent that protective cover from dropping in automotive operation, the cover body endoporus can adopt the mode of interference fit to be connected with outer nut; The cover body lower end also can boss and the opening elastic groove that be symmetrical in the center of circle be set in the cover body bottom, so that can be stuck in the following chamfering place of outer nut; Can also adopt the mode of on cover cap, establishing connecting bore, protective cover is connected on the motor tire inner nut with fastener.
The utility model has the advantages that: simple in structure, make easy for installation.Can protect the screw thread binding site of automotive tyre nut effectively; be not subjected to the influence of road conditions and external environment; avoid screw thread corrosion and distortion, thereby it is convenient and strength-saving to make that automotive tyre nut removes and installs, to having played positive effect the service life that prolongs lug nut and bolt.
