[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0028] A tire-mounting aid for small vehicles, such as Figure 1 As shown, the system includes a mounting frame 1. The top of the mounting frame 1 is respectively provided with a first fixing plate 2, a second fixing plate 3, and a third fixing plate 4. The first fixing plate 2 and the second fixing plate 3 (see reference) Figure 2Mounting shafts 5 are rotatably connected between the first and third fixing plates 4. The two ends of the mounting shafts 5 extend through the first fixing plate 2, the second fixing plate 3, and the third fixing plate 4 respectively, and are threaded externally. Rollers 6 are fitted onto the outer periphery of both mounting shafts 5. A multi-arc connecting piece 7 is fixedly connected to the side of the mounting frame 1 closest to the second fixing plate 3 and the third fixing plate 4. Several sliding wheels 8 are located at the bottom of the multi-arc connecting piece 7. Through the cooperation of the first fixing plate 2, the second fixing plate 3, the third fixing plate 4, the mounting shafts 5, and the rotating rollers 6, the tire can be easily rotated and adjusted during installation. The multi-arc connecting piece 7 and the sliding wheels 8 work together, and by pushing, pulling, and pressing down the multi-arc connecting piece 7, the angle and height of the mounting frame 1 can be easily adjusted, significantly reducing manpower input. A single person can easily complete the tire installation operation, increasing efficiency several times compared to traditional methods.

[0029] like Figure 2 As shown, fixing plates 1 (2), 2 (3), and 3 (4) are all provided with rectangular holes 9 of the same size as both ends of the mounting shaft 5. The protruding ends of both ends of the mounting shaft 5 are threaded with fastening nuts 10 that are compatible with the external threads. By providing the rectangular holes 9 and fastening nuts 10, when installing tires of different sizes, the distance between the two mounting shafts 5 can be adjusted, and the fastening nuts 10 can be tightened to accommodate different tire sizes, greatly improving flexibility.

[0030] like Figure 2 As shown, the rectangular hole 9 has several positioning grooves 11 of the same size as the fastening nut 10 on the outer end faces of the fixing plate 1, fixing plate 2, fixing plate 3, and fixing plate 4. By setting the positioning grooves 11, when the fastening nut 10 is tightened to fasten the mounting shaft 5, the fastening nut 10 is aligned with the positioning grooves 11 and tightened, preventing the mounting shaft 5 from shifting due to external force during the mounting process, thus improving the stability of the mounting shaft 5.

[0031] like Figure 1 As shown, several anti-slip round strips 12 are welded to the outer peripheral walls of both rollers 6. By setting the anti-slip round strips 12, when the position and height of the mounting frame 1 need to be adjusted during the tire mounting process, the anti-slip round strips 12 can prevent the tire from falling off the two rollers 6, thus ensuring construction efficiency.

[0032] like Figure 1 As shown, a rubber pad 13 is provided at the bottom of the side of the mounting frame 1 closest to the fixing plate 2. By providing the rubber pad 13, the rubber pad 13 can effectively buffer the direct contact between the mounting frame 1 and the ground, avoid wear caused during installation, and also reduce the noise emitted by the mounting frame 1 and the ground.

[0033] like Figure 1As shown, a through hole 14 is provided in the middle of the mounting frame 1. By providing the through hole 14, when installing some larger tires, the through hole 14 can prevent the tire from rubbing against the mounting frame 1, ensuring smooth efficiency when rotating and adjusting the tire.

[0034] The working process and beneficial effects of this utility model are as follows: Based on the actual size of the tire, the distance between the mounting shafts 5 is adjusted, and then the fastening nut 10 is tightened. The tire to be installed is then placed on the two rotating rollers 6. The operator then slowly pushes the tire mounting tool closer to the vehicle's wheel hub with one hand. During the process, if there are deviations in angle or height, adjustments can be made using the multi-arc connecting piece 7 and the sliding wheel 8 until the tire bolt holes are precisely aligned with the bolts on the vehicle's wheel hub.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
