Technical Field

[0001] The utility model relates to the technical field of automobile maintenance, in particular to a tire fixing frame for automobile maintenance. Background Art

[0002] At present, automobile maintenance is a general term for automobile care and repair, which means to check the faulty automobile through technical means, find out the cause of the fault, and take certain measures to eliminate the fault and restore it to a certain performance and safety standard. Automobile maintenance includes automobile overhaul and automobile minor repair. Automobile overhaul refers to the restorative repair that repairs or replaces any parts of the automobile (including basic parts) to restore the automobile to its good technical condition and completely (or nearly completely) restore the life of the automobile. Automobile minor repair refers to the operational repair that replaces or repairs individual parts to ensure or restore the working ability of the automobile.

[0003] Among them, with the rapid development of the automobile industry, cars are becoming more and more popular, and car maintenance work is becoming more and more onerous. Tires are an important part of cars, and the life of tires will gradually decrease with long-term use, consumption, and wear. Moreover, in many cases, due to various special circumstances, tires will suffer varying degrees of damage. Therefore, the maintenance and replacement of tires is also extremely onerous.

[0004] When the tire is inspected and repaired, it needs to be fixed. Usually, two people are needed to cooperate during the repair, one to help fix the tire, and the other to inspect and repair it. The work intensity is high, time-consuming and labor-intensive, and the efficiency is low, which is extremely inconvenient. Therefore, it is necessary to design a new technical solution to solve the problem, so that the tire can be inspected and repaired quickly and labor-savingly. Utility Model Content

[0009] As an optional solution of the technical solution of the present application, a spring is sleeved on the other end of the rotating rod, and a support ring is fixedly installed on the other end of the spring. The support ring fits against the side wall of the positioning frame to support the support rod.

[0010] As an optional solution of the technical solution of the present application, a groove is opened in the middle of the mounting frame, and the groove corresponds to the positioning frame to facilitate the adjustment of the rotating rod.

[0011] As an optional solution of the technical solution of the present application, a screw hole is opened in the middle of the mounting seat on the top side, a screw rod is spirally connected in the screw hole, and the bottom of the screw rod is rotatably mounted on the top of the positioning frame, so that the positioning frame can be adjusted.

[0012] As an optional solution of the technical solution of the present application, a piston cylinder is fixedly installed at the other end of the two groups of brackets, and cross bars are movably installed on both sides of the two groups of piston cylinders to facilitate insertion into the wheel hub to fix the tire.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The technical solution of the present application places the tire that needs to be repaired on the top of two sets of rollers and ensures that the tire is in a vertical state. At the same time, the rotating rod is turned in the extrusion support mechanism so that the two sets of brackets fixedly installed at the other end of the rotating rod are both inserted into the wheel hub inside the tire. The cross bar in the piston cylinder is pulled out, and one end of the two sets of brackets can be fixed on both sides of the tire. This can not only ensure that the tire makes a circular motion on the top of the two sets of rollers and perform a comprehensive inspection of the tire surface, but also when the tire is rotating, it can be firmly supported by the rotating rod on one side of the two sets of brackets to prevent the tire from tipping over during the rotation process.

[0015] 2. The technical solution of the present application is that a screw is spirally connected in a screw hole, and the bottom of the screw is rotatably installed with the top of the positioning frame. When tires of different sizes are placed on the top of the two sets of rollers, the screw in the screw hole can be screwed in to adjust the height of the positioning frame. After the rotating groove in the middle of the positioning frame is aligned with the center of the tire, it can be ensured that the tire rotates with the rotating groove of the positioning frame as the center, so that the device can fix and repair tires of different sizes.
