For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1-3As shown, a car balancing hoist for automobile repair is convenient, including a column 1, a base 2 is provided at the lower end of the column 1, the column 1 is hollow inside and is installed with a screw, a screw pair 3 is installed on the screw, the screw pair 3 is fixedly connected with a fixed arm 4, the screw is driven to rotate by a motor 5, a long slot 6 is provided on one side of the column 1, the fixed arm 4 extends out of the long slot 6 and can move up and down in the long slot 6, one end of the fixed arm 4 extending out of the long slot 6 is connected with a supporting arm 7, the end of the supporting arm 7 is connected with a supporting plate 8, the lower end of the supporting plate 8 is fixedly connected with a mounting plate 9, a plurality of threaded holes 10 are provided around the mounting plate 9, and the threaded holes 10 are respectively threadedly connected with an adjusting rod 11, the lower end of the adjusting rod 11 is provided with a nut 12, and the upper end of the adjusting rod 12 is connected with a pad 13 after passing through the threaded hole 10, and the supporting plate 8 is surrounded by the adjusting rod 11. When in use, the motor 5 drives the screw to rotate, thereby driving the fixed arm 4 to drive the supporting arm 7 to rise or fall. The supporting plate 8 supports the designated position of the chassis of the car. When the car is overweight and shows signs of tilting and sliding, the pad 13 can be used on the chassis of the car by rotating the adjusting rod 12. This can increase the contact area between the hoist and the chassis of the car and improve the anti-skid effect. Secondly, the uneven adjusting rod 12 in contact with the chassis can be adjusted to form a blocking effect to further prevent the car from sliding. Thirdly, when the center of gravity of the car deviates seriously, the supporting arms 7 of the hoist around the car can form a certain height difference, thereby adjusting the center of gravity of the car to keep it stable.

[0019] Furthermore, a circular groove 14 is provided inside the cushion block 13, and a through hole 15 communicating with the circular groove 14 is provided on the lower surface of the cushion block 13, the diameter of the through hole 15 is smaller than the diameter of the circular groove 14, and the through hole 15 is coaxial with the circular groove 14. The upper end of the adjusting rod 11 passes through the through hole 15 and then extends into the circular groove 14 and is fixedly connected with a circular plate 16, the diameter of the circular plate 16 is smaller than the diameter of the circular groove 14, and the diameter of the circular plate 16 is larger than the diameter of the through hole 15. In this way, the cushion block 13 will no longer rotate after contacting the automobile chassis, while the adjusting rod 11 can continue to rotate, reducing the influence of the adjusting rod 11 on the automobile chassis.

[0020] Furthermore, the cushion block 13 is made of wear-resistant rubber.

[0021] Furthermore, the support arm 7 is hinged to the fixed arm 4 via a vertically arranged hinge shaft. The support arm 7 rotates to one side of the column 1 without affecting the movement of the car beside the lift. The angle of the support arm 7 can be adjusted to meet the use needs of different models.

[0022] Furthermore, a low safety bar 17 is provided on one side of the column 1, and a high safety bar 18 is provided on the other side. The structure of the high safety bar 18 is the same as that of the low safety bar 17, and the length of the high safety bar 18 is longer than that of the low safety bar 17. A slide rail is provided on the base 2, and the middle of the slide rail is located directly below the fixed arm 4. Both ends of the slide rail are bent and extended to one side of the column 1. Two sliders 19 are installed on the slide rail. The lower end of the high safety bar 18 is fixedly connected to one slider 19, and the lower end of the low safety bar 17 is fixedly connected to another slider 19. After the car is lifted to a certain height, the low safety bar 17 is moved to the bottom of the fixed arm 4 to form a safety protection. At this time, the hand is slightly applied to the car body, and it can be quickly found out whether the car is overweight and the overweight situation by observation, so as to judge whether the car can continue to be lifted, or whether it is suitable to use the adjustment rod 11 to adjust the center of gravity of the car. When the center of gravity of the automobile is stabilized, the automobile is lifted to the highest position again, and the high-position safety bar 18 is moved to the right below the fixed arm 4, and the high-position safety bar 18 is used to form a safety protection. When the automobile needs to be lowered, the high-position safety bar 18 is moved to one side of the column 1.

[0023] Further, the slide rail is composed of a slide groove 20, the slide groove 20 is covered with a cover plate 21, and the cover plate 21 is provided with a movable long hole 22 matching the slide groove 20, the width of the movable long hole 22 is smaller than the width of the slide groove 20, the slider 19 is a circular slider, a plurality of universal balls are installed on the lower surface of the circular slider, the diameter of the circular slider is larger than the width of the movable long hole 22, and the high safety rod 18 and the low safety rod 17 are respectively movable through the movable long hole 22. The cooperation of the circular slider with the slide groove 20 and the movable long hole 22 enables the high safety rod 18 and the low safety rod 17 to maintain a vertical state, and at the same time facilitates the use of the high safety rod 18 and the low safety rod 17.

[0024] Furthermore, a bayonet 23 is provided in the middle of the slide groove 20 near the side of the column 1, a clamping plate 24 is provided in the middle of the slide groove 20, a clamping edge 25 is provided at one end of the clamping plate 24 near the bayonet 23, the other end of the clamping plate 24 is set as a mounting end 26, springs 27 are respectively provided on both sides of the mounting end 26, a spring mounting groove 28 for mounting the spring 27 is provided on the base 2, the mounting end 26 is located in the spring mounting groove 28 and clamped between the springs 27, and inclined guide edges 29 are respectively provided on both sides of the clamping plate 24. When the high safety rod 18 or the low safety rod 17 is moved to the bottom of the fixed arm 4, the clamping plate 24 overcomes the elastic force of the spring on one side and moves in the slide groove 20, so that the high safety rod 18 or the low safety rod 17 can be moved into the clamping slot 23, and then the clamping plate 24 automatically resets and the high safety rod 18 or the low safety rod 17 can be clamped in the clamping slot 23, preventing the high safety rod 18 or the low safety rod 17 from being moved by mistake, thereby improving the safety performance of the hoist.

[0025] Further, a kick plate 30 is fixedly connected to the clamping plate 24, and the kick plate 30 can be movably extended out of the movable long hole 22. The clamping plate 24 can be quickly and conveniently moved by the kick plate 30, so that the high safety bar 18 or the low safety bar 17 is moved out of the clamping port 23.
