[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1,

[0028] Please see Figure 1 and 4 As shown, a car repair lift includes a lifting platform 1 and a support column 101. A rectangular groove 102 is formed on the top of the lifting platform 1. A transmission assembly is fixed inside the support column 101 to drive the lifting platform 1 to rise and fall. Multiple mounting grooves 2 can be provided on the top of the lifting platform 1 outside the rectangular groove 102. Two circular rollers 201 are rotatably connected to the inner cavity of each mounting groove 2. By setting the circular rollers 201, four sets of circular rollers 201 are provided on the top of the lifting platform 1. Each set of circular rollers 201 consists of two circular rollers 201. The circular rollers 201 are located on the car's driving path. When the car travels to the two... When the rollers 201 are in place, the user can remove the pins 203 that fix the rollers 201, allowing the rollers 201 to rotate freely. During the lifting process, even if the wheels and tires rotate, it will only drive the rollers 201 to rotate and will not change the position of the car, ensuring the stability of the car. One end of the rollers 201 and one side of the lifting platform 1 are fixed with limit blocks 202. The inner cavity of the limit blocks 202 is slidably connected with pins 203. The top of the lifting platform 1 outside the mounting groove 2 is equipped with a mounting block 3. The inner cavity of the mounting block 3 is rotatably connected with an auxiliary component for holding the car.

[0029] First, drive the car onto the top of the lifting platform 1, positioning it between the four sets of rollers 201. The user then removes the pin 203 from the inner cavity of the limiting block 202, allowing the rollers 201 to rotate freely. The lifting platform 1 is then activated to lift the car as a whole. Even if the wheels and tires rotate, it will only cause the rollers 201 to rotate and will not change the car's position. During the lifting process, workers can inspect the bottom of the car through the rectangular slot 102. After the inspection is completed, the lifting platform 1 is lowered, the pin 203 is reinserted into the inner cavity of the limiting block 202 to fix the rollers 201, and the car is driven away from the lifting platform 1.

[0030] Example 2,

[0031] As one specific embodiment of this utility model, such as Figure 1 , 2As shown in Figures 3, 5, and 6, the transmission assembly includes a threaded rod 4, which is rotatably mounted in the inner cavity of the support column 101. A guide column 401 is fixed in the inner cavity of the support column 101. Sliding blocks 402 are slidably connected to the surfaces of the threaded rod 4 and the guide column 401. One side of the sliding block 402 is fixedly connected to one side of the lifting platform 1. A drive motor 403 is fixed to one end of the threaded rod 4. The auxiliary assembly includes a take-up roller 5, which is rotatably mounted in the inner cavity of the mounting block 3. A rope 501 is fixed to the surface of the take-up roller 5, and a hook 502 is fixed to the inner cavity of the rope 501. The surface of the take-up roller 5 on one side of the mounting block 3 is... A gear 503 is fixedly mounted. A locking block 504 is rotatably connected to one side of the mounting block 3 on the outer side of the gear 503. The bottom of the locking block 504 engages with the surface of the gear 503. An adjusting handle 6 is fixed to one end of the take-up roller 5. By adjusting the handle 6, rotating the handle 6 can drive the take-up roller 5 to rotate. A placement groove 7 is provided on the top of the mounting block 3. The inner cavity of the placement groove 7 can store some maintenance and inspection tools. Multiple anti-slip grooves 8 are provided on the top of the lifting platform 1. By providing anti-slip grooves 8, the anti-slip grooves 8 can prevent the vehicle from slipping when it drives onto the top of the lifting platform 1.

[0032] When the height of the lifting platform 1 needs to be adjusted, the drive motor 403 can be started. The start of the drive motor 403 will cause its internal rotor to rotate, which in turn will drive the threaded rod 4 connected to it to rotate. The rotation of the threaded rod 4 can be converted into the linear motion of the sliding block 402. Specifically, as the threaded rod 4 rotates, the sliding block 402 will move up and down along the rotation direction of the threaded rod 4. Since there is a connection between the sliding block 402 and the lifting platform 1, when the sliding block 402 is raised or lowered, it will drive the lifting platform 1 to rise or fall together. During the entire raising and lowering process, the lifting platform 1 moves along the guiding direction of the guide column 401. The guide column 401 plays a key guiding role, ensuring the stability and accuracy of the lifting platform 1 during the raising and lowering process.

[0033] When further enhancing the safety factor during the car lifting process is required, first rotate the locking block 504 to disengage it from the gear 503. Then, pull the rope 501, causing the take-up roller 5 to rotate, lengthening the rope 501. Connect the rope 501 to the car's tow hook via the hook 502. After connection, rotate the locking block 504 again to engage it with the gear 503. Then, rotate the adjusting handle 6, which in turn rotates the take-up roller 5 and winds up the rope 501. Because the locking block 504 engages with the gear 503, the winding roller 5 can only wind and tighten the rope 501. The locking block 504 will lock the gear 503, preventing the winding roller 5 from rotating. Once the rope 501 is wound and tightened, the rope 501 and hook 502 can then hold the car, further improving the safety factor during the car lifting process. When it is necessary to remove the hook 502, rotate the locking block 504 so that the locking block 504 is no longer engaged with the gear 503. At this time, stretch the rope 501 and remove the hook 502.
