Description

Technical Field

[0001] The utility model belongs to the technical field of tools, and in particular relates to a portable step-pry type tire removal tool. Background Art

[0002] When a car is driving outdoors, especially in the wild, its tires may be punctured and need to be replaced. When removing the tires of large vehicles such as trucks, the operator generally first uses a jack to lift the car until the tires are off the ground, and then uses a wrench or other tool to remove the screws that fix the tires to the axles. When removing the tires from the axles, since the tires of large vehicles such as trucks are large and heavy, the greater gravity of the tires presses on the axles to form a greater friction force, making it difficult to remove the tires from the axles. Some tire removal machines and equipment in repair shops are large and not portable. Therefore, it is necessary to design a portable tool to facilitate the removal of car tires, so as to facilitate the replacement of tires outdoors, especially in the wild. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies in the prior art and to provide a portable skid-type tire removal tool. The utility model can remove the tire from the axle more quickly and conveniently.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a portable pedal-type tire removal tool, characterized in that it includes a pry plate, a wheel, and a nut; one end of the pry plate has a concave notch so that this end of the pry plate forms two fork teeth; two side surfaces in the middle of the pry plate are symmetrically fixedly connected with a shaft rod; the shaft rod passes through the axis of the wheel; the nut is located on the outside of the wheel and is fixedly connected to the outer end of the shaft rod.

[0005] The above-mentioned portable pedal-type tire removal tool is characterized in that the wheels can rotate around the shaft.

[0006] Compared with the prior art, the utility model has the following advantages:

[0007] 1. The utility model can remove tires, especially tires of large vehicles, from axles more quickly and conveniently;

[0008] 2. Compared with some larger and non-portable tire removal machines and equipment in repair shops, the utility model is small in size and therefore easy to carry, and is suitable for removing tires outdoors, especially in the wild;

[0009] 3. The utility model has a simple structure, simple and easy manufacturing and assembly processes, low cost, simple operation, convenient use, easy processing and manufacturing, and is conducive to popularization and use.

[0010] The present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1 , Figure 2 As shown, the utility model includes a pry plate 1, a wheel 2, and a nut 3; one end of the pry plate 1 has a concave notch, so that the end of the pry plate 1 forms two fork teeth 11; two side surfaces of the middle part of the pry plate 1 are symmetrically fixedly connected with a shaft rod 12; the shaft rod 12 passes through the axis of the wheel 2; the nut 3 is located on the outside of the wheel 2 and is fixedly connected to the outer end of the shaft rod 12 to prevent the wheel 2 from falling off the shaft rod 12; the wheel 2 can rotate around the shaft rod 12.

[0017] The working principle of the utility model is: when in use, Figure 2 As shown, the operator first uses a jack to lift the car until the car tire 4 is off the ground, then uses a wrench or other tools to remove the screws that fix the car tire 4 to the axle 5, and then points the two fork teeth 11 at one end of the prying plate 1 toward the lower end of the car tire 4, and inserts the two fork teeth 11 at one end of the prying plate 1 into the gap between the lower part of the car tire 4 and the ground; the operator steps on the end of the prying plate 1 without fork teeth with one foot, and through the downward force of the foot and the lever principle of the fulcrum formed by the shaft rod 12 and the wheel 2, the fork teeth pry the car tire 4 upward, thereby reducing the car tire 4. The friction force formed by the weight of the tire 4 pressing on the axle 5 is used by the operator to pull the upper part of the tire outward with both hands, and step on the prying plate 1 with one foot, and use the friction force of the sole of the foot to pull the prying plate 1 outward with the foot. Since the prying plate 1 is equipped with a wheel 2 through a shaft 12, the prying plate 1 can lift the tire 4 of the car through the two fork teeth 11 thereon, so that the tire 4 of the car is lifted up by the utility model, and as the wheel 2 installed on the prying plate 1 through the shaft 12 rolls, the tire 4 of the car is easily removed from the axle 5.
