Description

Technical Field

[0001] The utility model relates to a portable vehicle tire disassembly device, belonging to the technical field of vehicle maintenance tools. Background Art

[0002] The tires of large vehicles often need to be removed, replaced or repaired. When removing the tires, you need to first use a jack to lift the frame to slightly lift the tire off the ground, then remove the bolts that fix the tire one by one and remove the tire from the axle. Since the tires of large vehicles are relatively heavy, it is very difficult to remove the tires from the axle. It requires two people to cooperate and move them out little by little, which is labor-intensive and time-consuming, reducing the efficiency of vehicle maintenance. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a portable vehicle tire removal device that can assist in removing tires, reduce the labor intensity during tire removal, and improve vehicle maintenance efficiency.

[0004] The portable vehicle tire removal device of the utility model comprises a sled plate. A handle is arranged on the rear side of the sled plate. The sled plate is used for prying the tire. A retractable draw hook is arranged on the handle. The draw hook is used for assisting in pulling the tire.

[0005] The technical solution of the utility model is to provide a portable vehicle tire removal device. When removing the tire of a large vehicle, a skid is placed under the tire, and a hook is used to hook the opening on the wheel hub, and the handle is continuously shaken up and down to remove the tire from the wheel axle.

[0006] Preferably, the sled plate is a steel plate with a folded angle greater than 90 degrees, and a circular arc surface is provided at the front end of the sled plate.

[0007] Furthermore, a fixed shaft is provided on the sled plate, and bearings are installed at both ends of the fixed shaft to facilitate the device to drive the tire to slide and serve as a fulcrum for prying the tire.

[0008] Preferably, reinforcing ribs are provided on both sides of the sled board to increase the strength of the sled board.

[0009] Preferably, the handle is provided with a hanging rod, a wire rope tensioner is hung on the hanging rod, and an adjustment handle for adjusting the tightness of the wire rope is provided on one side of the wire rope tensioner.

[0010] Furthermore, a steel wire rope is arranged around the steel wire rope tensioner, and a draw hook is fixed to the front end of the steel wire rope.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The portable vehicle tire removal device described in the utility model only requires holding the handle to remove the tire from the wheel axle through the cooperation of the skid plate and the draw hook, and the tire is moved with the assistance of the bearing. The tire removal work can be completed by a single person, which reduces the labor intensity during tire removal and improves vehicle maintenance efficiency. The utility model has a simple structure, is easy to use, and is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with specific embodiments.

[0017] However, the description of the present invention is merely an embodiment of structural and even functional description, and the scope of rights of the present invention is not limited by the embodiments described in the text.

[0018] For example, multiple embodiments may have multiple changes and multiple forms, and it should be understood that the scope of rights of the present utility model includes equivalents that can realize the technical idea.

[0019] like Figures 1-2 As shown, this embodiment is implemented by the following technical solution: it includes a sled 1, a handle 5 is provided on the rear side of the sled 1, the sled 1 is used to pry the tire 8, and a retractable hook 6 is provided on the handle 5, and the hook 6 is used to assist in pulling the tire.

[0020] In this embodiment, the sled board 1 is a steel plate with a folded angle greater than 90 degrees, so that the handle 5 is tilted backward, and the front end of the sled board 1 is provided with an arc surface; the sled board 1 is provided with a fixed shaft 2, and bearings 3 are installed at both ends of the fixed shaft 2 to facilitate the device to drive the tire 8 to slide and serve as a fulcrum for prying the tire 8. Reinforcing ribs 7 are provided on both sides of the sled board 1 to increase the strength of the sled board 1.

[0021] The handle 5 is provided with a hanging rod 51, on which a wire rope tensioner 4 is suspended, and one side of the wire rope tensioner 4 is provided with an adjustment handle 41 for adjusting the tightness of the wire rope. The wire rope tensioner 4 is surrounded by a wire rope, and a draw hook 6 is fixed to the front end of the wire rope.

[0022] The method of using the utility model is:

[0023] Lift the frame with a jack to lift the tire 8 slightly off the ground, place the sled 1 under the tire 8, adjust the hook 6 to a suitable position, hook the opening on the wheel hub, and continuously shake the handle 5 up and down to remove the tire from the wheel axle through the prying of the sled 1 and the pulling force of the hook 6; if the tightness of the wire rope is not appropriate during this period, it can be adjusted by adjusting the handle 41.

[0024] Of course, the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and any equivalent changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention shall fall within the scope of the patent coverage of the present invention.
