[0002] Automobile maintenance is a general term for automobile maintenance and repair. It is to use technical means to check the faulty car, find out the cause of the fault, and take certain measures to eliminate the fault and restore it to a certain performance and safety standard. As one of the three major parts of a car, the chassis of the car has a very important impact on the quality of the car. However, when the car is driving, the chassis is at the bottom and close to the ground, so it is easy to be damaged.

[0003] In traditional maintenance methods, workers usually need to enter the bottom of the car to perform maintenance. However, due to the extremely limited space under the car, the range of motion of the workers' arms is greatly restricted during the maintenance process, making it difficult to carry out maintenance work efficiently, and thus greatly reducing the repair efficiency; existing lifting devices generally use jacks or hoists to lift cars. Although jacks are small and convenient, they directly apply force to the car, and the force is uneven, which can easily cause secondary damage to the car. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the utility model provides a lifting platform for automobile repair, which can effectively solve the problem of uneven force applied to the automobile by the jack in the prior art.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example: Refer to Figures 1 to 6 A lifting platform for automobile repair includes a base 1, wherein two rectangular cavities are provided inside the base 1, and two through slots 19 are provided on the top of each rectangular cavity, and the two through slots 19 are symmetrically arranged, and two sliders 7 are slidably installed inside each rectangular cavity, and the two sliders 7 are arranged oppositely, and a bidirectional screw 6 is rotatably installed inside one of the rectangular cavities, and the bidirectional screw 6 is respectively threadedly connected with the two sliders 7, and a guide column 9 is fixedly installed inside the other rectangular cavity, and the guide column 9 is slidably connected with the other two sliders 7, and a motor 18 is fixedly installed on the side wall of the base 1, and the output end of the motor 18 movably passes through the side wall of the base 1 and is fixedly connected with one end of the bidirectional screw 6, and two support plates 12 are arranged on the top of the base 1, and two Articulated seats 8 are fixedly installed on both sides of the bottom of the support plate 12 and on the tops of the four sliders 7. A connecting rod 10 is rotatably installed between each of the two corresponding upper and lower articulated seats 8. A sliding mechanism is provided on the top of the base 1. When the car to be repaired is located on the top of the two support plates 12, the motor 18 is started, and the output end of the motor 18 drives the bidirectional screw 6 to rotate, thereby driving the two sliders 7 in the same rectangular cavity to approach each other. Since the connecting rod 10 is hinged to the support plate 12 and the slider 7 respectively through the two articulated seats 8, when the two sliders 7 approach each other, the height of the support plate 12 can be adjusted to raise the car to be repaired, and then the staff moves under the car through the sliding mechanism to repair the bottom of the car.

[0024] Specifically, refer to Figure 4 A connecting column 11 is fixedly installed between each two corresponding connecting rods 10 at the front and rear ends to ensure that the two adjacent connecting rods 10 move together, thereby ensuring the stability of the support plate 12.

[0025] Further, refer to Figure 5 The sliding mechanism includes a lying board 2, and two sliding rails 3 are provided at the bottom of the lying board 2. The two sliding rails 3 are arranged opposite to each other. Two limit blocks 5 are fixedly connected to the top of the base 1. The two limit blocks 5 are arranged opposite to each other. The two limit blocks 5 are slidably installed inside the two sliding rails 3. A plurality of ball bearings 4 are provided at the bottom of the lying board 2. After the height adjustment of the car to be repaired is completed, the staff pulls the lying board 2, and under the joint action of the sliding rails 3 and the limit blocks 5, the lying board 2 is moved out from the base 1. The staff lies on the lying board 2 and resets the lying board 2 by using their legs. Then the staff moves under the car to repair the car. The setting of the ball bearings 4 reduces the friction between the lying board 2 and the base 1, thereby facilitating the movement of the lying board 2.

[0026] Further, refer to Figure 2 A tilting plate 17 is fixedly connected to the side wall of one of the support plates 12, a second stopper 16 is clamped on the top of the support plate 12, and a first stopper 14 is fixedly installed on the top of the other support plate 12.

[0027] Further, refer to Figures 1 to 3 A plurality of guide posts 15 are fixedly installed on the top of the base 1. The plurality of guide posts 15 are respectively located at the four corners of the top of the base 1, and each guide post 15 is movable through the corresponding support plate 12. Two connecting frames 13 are fixedly installed between the two support plates 12, which play a certain stabilizing role on the support plates 12, prevent the car from falling off during lifting, and reduce damage to the car and personnel.

[0028] The working principle of the utility model is as follows:

[0029] When in use, the car moves to the top of the two support plates 12 through the tilting plate 17, and then the second stopper 16 is stuck in the top of one of the support plates 12. Under the joint action of the first stopper 14, the car is limited to prevent the car from moving during the lifting period, which may cause a safety accident. The motor 18 is started, and the output end of the motor 18 drives the bidirectional screw 6 to rotate, thereby driving the two sliders 7 in the same rectangular cavity to approach each other. Since the connecting rod 10 is respectively hinged to the support plate 12 and the slider 7 through two hinge seats 8, when the two sliders 7 approach each other, The height of the support plate 12 can be adjusted to raise the car to be repaired. At the same time, the connection frame 13 and the guide column 15 can prevent the car from falling off during lifting and lowering, thereby reducing damage to the car and personnel. The staff pulls the lying board 2, and under the joint action of the slide rail 3 and the limit block 5, the lying board 2 is moved out from the base 1. The staff lies on the lying board 2 and resets the lying board 2 with their legs. Then the staff moves under the car to repair the car. The setting of the ball 4 reduces the friction between the lying board 2 and the base 1, thereby facilitating the movement of the lying board 2.
