[0022] 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.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an adjustable car chassis lifting device, comprising a base 1, scissor lift rods 2 installed on both the front and rear sides of the upper end of the base 1, a hydraulic rod 3 installed on the right side of the scissor lift rods 2, a lifting platform 4 installed on the upper end of the scissor lift rods 2, and support plates 5 connected to the upper left and right sides of the upper end of the lifting platform 4 via rotating components. The rotating components include rotating shafts 12 rotatably connected to the upper left and right sides of the lifting platform 4, the upper outer wall of the rotating shafts 12 being fixedly connected to the middle of the support plates 5, and a worm gear 11 being fixedly connected to the lower outer wall of the rotating shafts 12. Fixing plates 13 are fixedly connected to the lower left and right sides of the lifting platform 4, and a worm gear 10 is rotatably connected to the opposite end of the fixing plates 13. The outer wall of the worm gear 10 is meshed with the outer wall of the worm gear 11, and a knob 9 is fixedly connected to the opposite end of the worm gear 10. The opposite end of the knob 9 is rotatably connected to the left and right ends of the lifting platform 4. A support plate 6 is fixedly connected to the upper end of the support plate 5.

[0024] Specifically, when the operator turns knob 9, knob 9 drives the worm gear 10, which is fixedly connected to it, to rotate. Since the worm gear 10 and the worm wheel 11 mesh with each other, the rotation of the worm gear 10 will cause the worm wheel 11 to rotate as well. The worm wheel 11 is fixed on the lower side of the outer wall of the rotating shaft 12, and the rotating shaft 12 is rotatably connected to the lifting platform 4. At the same time, the upper side of the outer wall of the rotating shaft 12 is fixedly connected to the middle of the support plate 5. Therefore, the rotation of the worm wheel 11 will drive the rotating shaft 12 to rotate, thereby causing the support plate 5 to rotate around the rotating shaft 12, realizing the adjustment of the angle of the support plate 5. By adjusting the angle of the support plate 5, the support plate 6 can better fit the chassis of different vehicle models, improving the adaptability of the device to various vehicle models. It can also ensure that the contact area between the support plate 6 and the chassis is maximized, thereby enhancing the support stability. The scissor lift rod 2 can evenly distribute the weight of the car, ensuring that the lifting platform 4 rises or falls smoothly. The hydraulic rod 3 provides a stable driving force, further enhancing the smoothness of the lifting process.

[0025] Reference Figure 1 and Figure 3The lower four corners of the base 1 are connected to support legs 16 via an adjustment assembly. The adjustment assembly includes screws 15 threaded to the upper four corners of the base 1. A knob 14 is fixedly connected to the upper end of the screw 15. The lower end of the screw 15 is fixedly connected to the upper end of the support leg 16. Circular holes 17 are provided at the lower four corners of the base 1. The inner diameter of the circular holes 17 matches the upper outer diameter of the support leg 16. Multiple universal wheels 8 are installed at the lower end of the base 1. A telescopic push handle 7 is fixedly connected to the upper right side of the base 1.

[0026] Specifically, by rotating knob 14, the screw 15 fixedly connected to it is driven to rotate. Since the screw 15 is threadedly connected to the base 1, according to the principle of thread transmission, the screw 15 will move up and down along the thread direction when rotating. Since the lower end of the screw 15 is fixedly connected to the upper end of the support leg 16, the up and down movement of the screw 15 will drive the support leg 16 to make corresponding lifting and lowering movements in the round hole 17, thereby realizing the adjustment of the height of the support leg 16. By adjusting the height of the support leg 16, the base 1 can be kept in a horizontal state, ensuring the stability of the entire lifting device. The universal wheels 8 and telescopic push handle 7 make the movement of the device very easy and convenient, so that the operator can easily move the device to different working positions.

[0027] Working principle: When repairing or inspecting the vehicle chassis, push the telescopic handle 7 and use the casters 8 to move the device to the position where the chassis needs to be raised or lowered. Then, depending on the flatness of the ground, turn the knob 14 to move the screw 15 up and down within the base 1, driving the outriggers 16 to rise or fall until the entire device is in a horizontal and stable state. Then, according to the shape and structure of the chassis to be raised or lowered, turn the knob 9 to rotate the worm gear 10, which in turn rotates the shaft 12 through the worm wheel 11, thereby adjusting the angle of the support plate 5 so that the support plate 6 can better fit the chassis. Then, activate the hydraulic rod 3 to extend it and push the scissor lift 2 to unfold, driving the lifting platform 4 to rise and raise the chassis. When it is necessary to lower, control the hydraulic rod 3 to retract, the scissor lift 2 to retract, and the lifting platform 4 to descend.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
