Description

Light-weight high-strength automobile exhaust pipe sleeve Technical Field The application relates to the field of automobile exhaust pipe sleeves, in particular to a lightweight high-strength automobile exhaust pipe sleeve. Background The automobile tail throat is commonly called an exhaust pipe sleeve, is a part arranged at the tail end of original exhaust, can protect an exhaust pipe, is not easy to damage and deform, can reduce noise emitted by the exhaust pipe, and can make sound slightly soft, so that driving environment is optimized, most important tail throats are made of materials such as chrome plating and are fixed on an original iron exhaust port, and the aesthetic property ‌ of an automobile can be remarkably enhanced. However, traditional blast pipe sleeve can be installed on vehicle vent-pipe through a plurality of bolts, contradict through a plurality of bolts and blast pipe outer wall after the installation and realize the fixed to the blast pipe sleeve, because area of contact between tip and the blast pipe of bolt is less, therefore take place not hard up easily after the installation, thereby it is relatively poor to lead to the stability of installation, and some sleeves still can carry out the regulation of angle after the installation, can twist up the bolt and carry out the fixed of angle after the angle modulation is accomplished, because only the fixed of angle is realized by the frictional force between bolt and the sleeve, therefore take place not hard up easily, thereby lead to the fixed stability of angle is relatively poor, and general sleeve is a whole, need carry out whole change when the sleeve or sleeve of the different colours of needs to be changed take place to damage, thereby can increase the cost of using. Disclosure of Invention The application provides a lightweight high-strength automobile exhaust pipe sleeve, which aims to improve the stability of an exhaust pipe sleeve after installation, improve the stability of the sleeve after angle adjustment and save the use cost. The application provides a lightweight high-strength automobile exhaust pipe sleeve, which adopts the following technical scheme: The utility model provides a lightweight high strength vehicle vent-pipe sleeve, includes the adapter sleeve, fixedly connected with spliced pole on the adapter sleeve, rotate on the spliced pole and be connected with first connecting seat, first connecting seat fixedly connected with is in first sleeve, be equipped with adjusting structure on the adapter sleeve, the outside cover of adapter sleeve is equipped with the second sleeve, be equipped with limit structure on the adapter sleeve, be equipped with location structure on the adapter sleeve, be equipped with fixed knot structure on the first sleeve, fixed knot structure includes second thread bush and support the cover, threaded connection has the second thread bush on the first sleeve, rotate on the second thread bush and be connected with the support the cover, sliding connection has four sliders on the first sleeve, contradict between the one end of slider and the support cover, the other end fixedly connected with butt plate of slider, fixedly connected with first spring between slider and the first sleeve, be equipped with rotating-structure on the second thread bush. Through adopting above-mentioned technical scheme, through rotating the second thread bush of rotating-structure rotation, can drive to support the cover and move towards a plurality of sliders in the second thread bush pivoted, can contradict the slider and slide on first sleeve when moving towards the slider, first spring shrink, the slider slides and can drive to keep out the board and move towards vehicle vent-pipe, can stop rotating the second thread bush when supporting tightly between four keep out boards simultaneously and vehicle vent-pipe, owing to keep out the board and be convex structure, consequently, can increase the area of contact with vehicle vent-pipe, thereby can effectually improve vehicle vent-pipe sleeve stability after installation, and can make vehicle vent-pipe be in first telescopic middle part all the time after the installation through making four keep out the board simultaneously move towards vehicle vent-pipe, thereby accuracy when having improved the installation. Optionally, a plurality of notches are formed in the abutting sleeve, and the sliding block is located in the adjacent notches. Through adopting above-mentioned technical scheme, because the slider is located the inside of notch, consequently can restrict the motion of support the cover, avoid its and second thread bush to rotate together, the slider is located the inside of notch simultaneously also can increase the area of contact between support cover and the slider to make the support cover can be better contradict the slider motion. Optionally, the four retaining plates are distributed in a circumferential array with respect to the middle part of the f
