A protective rubber is fixedly attached to the lower end of the fixing plate. A handle is fixedly connected to one outer surface of the fixing plate. A lifting plate is movably connected to both outer surfaces of the U-shaped structure of the fixing plate.

[0004] To address the problems of existing tire lifting devices, such as cumbersome operation, slippage of severely worn tires leading to unstable tire fixation and potential slippage, resulting in poor safety, current technology employs protective rubber attached to the lower end of a fixing plate. This protects the fixing plate, reduces impact and wear, and extends the device's lifespan. Anti-slip rubber is also added inside the support bracket. However, these devices only limit their applicability to wheels of specific sizes. Utility Model Content

[0005] The purpose of this invention is to provide a single-sided lifting device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A single-sided lifting device includes a base mechanism, an adjustment mechanism at the top of the base mechanism, and a limit mechanism inside the adjustment mechanism.

[0008] The base mechanism includes a base, and two supports are provided on the top surface of the base. Limit pins are fixedly connected to the inner walls of the two supports, and a push cylinder is provided on the top surface of the bottom end of the supports.

[0009] A further improvement of this utility model is that: a connecting block is fixedly connected to the output end of the pushing cylinder, a swing arm is movably connected to the inner wall of the connecting block, and a limit bolt is provided at the top end of the swing arm.

[0010] A further improvement of the present invention is that the adjustment mechanism includes a connecting rod that passes through the bracket and is rotatably connected to the top of the bracket. Adjusting discs are fixedly connected to both ends of the connecting rod, and the surfaces of the two adjusting discs are provided with sliding grooves.

[0011] A further improvement of this utility model is that: the groove wall of the slide is slidably connected to the limiting pin; the surfaces of the two adjusting discs are provided with limiting screw holes; the adjusting discs are threadedly connected to the limiting bolts through the limiting screw holes; the top surface of the connecting rod is fixedly connected to a support bracket; and sliding grooves are provided on both sides of the top surface of the support bracket.

[0012] A further improvement of the present invention is that the limiting mechanism includes a motor bracket, a clamping plate, and a locking bolt. The motor bracket is fixedly installed on the side of the support bracket, and a servo motor is fixedly connected to the top surface of the motor bracket. The output shaft of the servo motor is fixedly connected to a bidirectional lead screw.

[0013] A further improvement of this utility model is that: the bidirectional lead screw passes through the support walls at both ends of the support bracket and is rotatably connected to the support walls at both ends of the support bracket; the outer wall of the bidirectional lead screw is threadedly connected to one end of the two clamping plates; and a guide rod is slidably connected to the other end of the two clamping plates.

[0014] A further improvement of this utility model is that: the guide rod is fixedly installed on the inner wall of the support bracket, and the top ends of the two clamping plates are threadedly connected to a limiting plate by locking bolts. The inner wall of the limiting plate is linearly and uniformly fixedly connected with multiple anti-slip pads.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a single-sided lifting device. By setting up a limiting mechanism composed of a motor bracket, guide rod, servo motor, clamping plate, locking bolt, limiting plate, anti-slip pad, and bidirectional lead screw, the components cooperate with each other to facilitate the limiting and fixing of car tires of different sizes, thereby facilitating car repair by maintenance personnel. When needed, simply start the servo motor. The output shaft of the servo motor drives the bidirectional lead screw to rotate, which causes one end of the two clamping plates threaded to the bidirectional lead screw to move towards each other on the bidirectional lead screw, and the other end of the clamping plates to move towards each other on the surface of the guide rod. This can fix and limit the wheel placed on the top surface of the support. At the same time, the anti-slip pad can further improve the friction and prevent the tire from slipping.

[0017] 2. This utility model provides a single-sided lifting device. It consists of a base mechanism comprising a base, bracket, limiting pin, push cylinder, connecting block, swing arm, and limiting bolt, and an adjustment mechanism comprising a support bracket, adjusting plate, slide groove, connecting rod, sliding groove, and limiting screw hole. These two mechanisms work together to lift the tire, facilitating maintenance by repair personnel. When needed, the push cylinder is activated, and its output end drives the swing arm to rotate via the connecting block. This causes the adjusting plate, fixedly connected to the swing arm, to slide within the slide groove via the limiting pin. The adjusting plate then drives the connecting rod to rotate, thereby rotating the support bracket to a suitable position, facilitating maintenance by automotive repair personnel.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a single-sided lifting device, including a base mechanism 1. An adjustment mechanism 2 is provided at the top of the base mechanism 1, and a limit mechanism 3 is provided inside the adjustment mechanism 2. The base mechanism 1 includes a base 11, and two supports 12 are provided on the top surface of the base 11. Limit pins 13 are fixedly connected to the inner walls of the two supports 12. A push cylinder 14 is provided on the top surface of the bottom end of the support 12. A connecting block 15 is fixedly connected to the output end of the push cylinder 14. A swing arm 16 is movably connected to the inner wall of the connecting block 15. A top end of the swing arm 16 is provided with... The limiting bolt 17 and the adjusting mechanism 2 include a connecting rod 24, which passes through the bracket 12 and is rotatably connected to the top of the bracket 12. The two ends of the connecting rod 24 are fixedly connected to adjusting discs 22. The surfaces of the two adjusting discs 22 are provided with sliding grooves 23. The groove walls of the sliding grooves 23 are slidably connected to the limiting pins 13. The surfaces of the two adjusting discs 22 are provided with limiting screw holes 26. The adjusting discs 22 are threadedly connected to the limiting bolt 17 through the limiting screw holes 26. The top surface of the connecting rod 24 is fixedly connected to a support bracket 21. The top surfaces of the support bracket 21 are provided with sliding grooves 25 on both sides.

[0027] In this embodiment, a base mechanism 1 consisting of a base 11, a bracket 12, a limiting pin 13, a push cylinder 14, a connecting block 15, a swing arm 16, and a limiting bolt 17, and an adjustment mechanism 2 consisting of a support bracket 21, an adjusting plate 22, a slide groove 23, a connecting rod 24, a sliding groove 25, and a limiting screw hole 26 are set up. The two work together to lift the tire, making it easier for maintenance personnel to perform maintenance. When needed, the push cylinder 14 is activated. The output end of the push cylinder 14 drives the swing arm 16 to rotate through the connecting block 15. This causes the adjusting plate 22, which is fixedly connected to the swing arm 16, to slide inside the slide groove 23 through the limiting pin 13. This causes the adjusting plate 22 to drive the connecting rod 24 to rotate, thereby rotating the support bracket 21 to a suitable position, which facilitates maintenance by automotive maintenance personnel.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the limiting mechanism 3 includes a motor bracket 31, clamping plates 34, and locking bolts 35. The motor bracket 31 is fixedly installed on the side of the support support 21. A servo motor 33 is fixedly connected to the top surface of the motor bracket 31. A bidirectional lead screw 38 is fixedly connected to the output shaft of the servo motor 33. The bidirectional lead screw 38 passes through the support walls at both ends of the support support 21 and is rotatably connected to the support walls at both ends of the support support 21. The outer wall of the bidirectional lead screw 38 is threadedly connected to one end of the two clamping plates 34. A guide rod 32 is slidably connected to the other end of the two clamping plates 34. The guide rod 32 is fixedly installed on the inner wall of the support support 21. The top ends of the two clamping plates 34 are threadedly connected to a limiting plate 36 through locking bolts 35. Multiple anti-slip pads 37 are fixedly connected linearly and uniformly to the inner wall of the limiting plate 36.

[0030] In this embodiment, a limiting mechanism 3 is provided, consisting of a motor bracket 31, a guide rod 32, a servo motor 33, a clamping plate 34, a locking bolt 35, a limiting plate 36, an anti-slip pad 37, and a bidirectional lead screw 38. The components cooperate with each other to facilitate the limiting and fixing of car tires of different sizes, thereby facilitating car repair by maintenance personnel. When needed, the servo motor 33 is started, and the output shaft of the servo motor 33 drives the bidirectional lead screw 38 to rotate. This causes one end of the two clamping plates 34, which are threaded to the bidirectional lead screw 38, to move towards each other on the bidirectional lead screw 38, and the other end of the clamping plates 34 to move towards each other on the surface of the guide rod 32. This can fix and limit the wheel placed on the top surface of the support bracket 21. At the same time, the anti-slip pad 37 can further increase the friction and prevent the tire from slipping.

[0031] The working principle of this single-sided lifting device will be explained in detail below.

[0032] like Figure 1-5 As shown, during use, the servo motor 33 is started, and the output shaft of the servo motor 33 drives the bidirectional lead screw 38 to rotate. This causes one end of the two clamping plates 34, which are threadedly connected to the bidirectional lead screw 38, to move towards each other on the bidirectional lead screw 38. This causes the other end of the clamping plates 34 to move towards each other on the surface of the guide rod 32. This can fix and limit the wheel placed on the top surface of the support bracket 21. At the same time, the anti-slip pad 37 can further increase the friction and prevent the tire from slipping. Then, the push cylinder 14 is started. The output end of the push cylinder 14 drives the swing arm 16 to rotate through the connecting block 15. This causes the adjusting plate 22, which is fixedly connected to the swing arm 16, to slide inside the slide groove 23 through the limiting pin 13. This causes the adjusting plate 22 to drive the connecting rod 24 to rotate, thereby rotating the support bracket 21 to a suitable position, which facilitates maintenance by automotive repair personnel.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
