[0006] As a preferred technical solution, the positioning components all include positioning rods and compression springs. The opposing surfaces of the positioning seats are provided with multiple positioning grooves in a ring structure. The two ends of the column are provided with guide grooves. One end of the positioning rod is inserted into the guide groove, and the other end is inserted into the corresponding positioning groove. The compression springs are all set inside the guide grooves. One end of the compression spring is installed on the inner wall of the guide groove, and the other end is installed on the end face of the positioning rod.

[0007] As a preferred technical solution, both sides of the positioning rod are provided with sliding grooves, and the inner side of the guide groove is equipped with a slide bar directly opposite the sliding groove. The slide bars are slidably set in the sliding groove.

[0008] As a preferred technical solution, the middle of the arc plate protrudes to form an adjustment part, which is set on both sides of the fixed seat. Each adjustment part is provided with a lead screw hole, and each fixed seat is provided with a mounting hole that penetrates the fixed seat. Each mounting hole is equipped with a ball bearing, and each ball bearing has a lead screw installed in its inner ring. Both ends of the lead screw are threaded into the lead screw hole, and a handwheel is installed at one end of the lead screw.

[0009] As a preferred technical solution, the fixing base is provided with a positioning port on one side of the mounting hole, and a positioning post is installed on the inner side of the arc plate opposite to the positioning port. The positioning posts are inserted into the positioning ports, and the cross-section of the positioning posts and the positioning ports are both rectangular.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a multi-station combined vehicle tire repair bracket, including a column 1. Both ends of the column 1 are embedded with sealed bearings 17. A shaft 18 is installed in the inner ring of each sealed bearing 17. A positioning seat 2 is installed at the other end of each shaft 18. A fixing frame 3 is installed on the outer end face of each positioning seat 2. Electric push rods 4 are installed at both ends of each fixing frame 3. The piston rods of the electric push rods 4 pass through the fixing frame 3 and are installed with fixing seats 5. Both sides of the fixing seat 5 are provided with arc-shaped plates 6 that position the tire and expand the outer wall of the tire outward. Positioning components that are inserted into the positioning seats 2 are installed at both ends of the column 1.

[0020] In this embodiment, each positioning component includes a positioning rod 11 and a compression spring 14. The opposite surface of the positioning seat 2 is provided with a plurality of positioning grooves 10 in an annular structure. Both ends of the column 1 are provided with guide grooves. One end of the positioning rod 11 is inserted into the guide groove, and the other end is inserted into the corresponding positioning groove 10. The compression springs 14 are all disposed inside the guide grooves. One end of the compression springs 14 is installed on the inner wall surface of the guide groove, and the other end is installed on the end face of the positioning rod 11.

[0021] In this embodiment, both sides of the positioning rod 11 are provided with sliding grooves 15, and the inner side of the guide groove is provided with a sliding strip 13 opposite to the sliding groove 15. The sliding strip 13 is slidably disposed in the sliding groove 15. The positioning rod is positioned by the slide groove and slide bar, so that the positioning rod can only move back and forth along the slide bar, which prevents the positioning rod from falling out of the guide groove and ensures the positioning effect of the positioning seat.

[0022] In this embodiment, the middle part of the arc plate 6 protrudes to form an adjustment part 7. The adjustment part 7 is provided on both sides of the fixed base 5. The adjustment part 7 is provided with a screw hole. The fixed base 5 is provided with a mounting hole that passes through the fixed base 5. A ball bearing 21 is installed in the mounting hole. A screw 16 is installed in the inner ring of the ball bearing 21. Both ends of the screw 16 are threaded to the screw hole. A handwheel 8 is installed at one end of the screw 16. The lead screw is centered on a ball bearing, and the threads on both sides of the center line of the lead screw are arranged in opposite directions, so that the adjusting part can be driven to open outward and close inward synchronously.

[0023] In this embodiment, the fixing base 5 is provided with a positioning port 19 on one side of the mounting hole, and the inner side of the arc plate 6 is provided with a positioning post 20 opposite to the positioning port 19. The positioning post 20 is inserted into the positioning port 19. The cross-section of the positioning post 20 and the positioning port 19 is rectangular. The curved plate can be positioned by the positioning pins and positioning openings, so that the curved plate can only open outwards along the positioning openings until the inner cavity of the tire is pushed outwards.

[0024] In this embodiment, a support base 9 is vertically installed on the column 1.

[0025] In this embodiment, grips 12 are installed on the outer surface of the positioning rod 11, which facilitates pushing the positioning rod.

[0026] During maintenance, the tire is placed on the outside of the arc plate, and the electric push rod is activated, causing the piston rod of the electric push rod to extend upward. The movement of the piston rod drives the fixed seat, which in turn drives the adjusting part and the arc plate simultaneously, allowing the arc plate to be inserted into the inside of the tire and contact the inner wall, thereby positioning the tire on one side of the column. Another tire can also be installed on the other side of the column, increasing the maintenance workstation and enabling maintenance operations for multiple tires. After the above is completed, rotate the handwheel. The rotation of the handwheel drives the lead screw, which in turn drives the adjustment unit. The adjustment unit can simultaneously drive the arc plate, so that the arc plate can be opened outward along the positioning port. The outward movement of the arc plate can open the inner cavity of the tire, so that the inner wall is fully exposed. To facilitate subsequent operations, the positioning rod can be pushed by gripping the lever. After the positioning rod moves out of the positioning slot, the tire can be rotated. The rotation of the tire drives the fixing frame and positioning seat, allowing the positioning seat to rotate around the shaft until the maintenance area is positioned below. This allows the operator to see the maintenance area clearly from top to bottom. Once the position is determined, the lever is released, and the rebound of the compression spring pushes the positioning rod outward, allowing it to re-insert into the positioning slot of the positioning seat. This positions the rotated positioning seat, fixing frame, and tire, ensuring stability during the maintenance process.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
