DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment of a foldable and simple vehicle-mounted hand-cranked lifting rack, comprising a used brake disc 1, a mounting disc 2 being fixedly connected to the top of the used brake disc 1, a support rod 4 being rotatably connected to the top of the mounting disc 2 via a damping shaft 23, a bevel gear 21 being fixedly connected to the outer bottom end of the support rod 4, a bevel gear 22 being movably connected to the inner wall through-hole of the mounting disc 2 via a bearing, a connecting block 9 being fixedly connected to the top of the support rod 4, a guide rod 10 being rotatably connected to the inner wall of the connecting block 9, the other end of the guide rod 10 being fixedly connected to a limiting member 12, the bottom of the limiting member 12 being rotatably connected to the guide rod 2 11, a bolt 8 being threadedly connected to the outer through-hole of the support rod 4, and a lifting assembly being installed on the outside of the support rod 4, which is used to lift the cable 7.

[0031] Furthermore, the waste brake disc 1 serves as a base with a relatively large cross-sectional area, providing good stability. The entire device is supported by the support rod 4, facilitating the hoisting of items. Through the cooperation of the first bevel gear 21 and the second bevel gear 22, the device can achieve angle adjustment in any direction. The damping rotating shaft 23 can provide appropriate resistance to prevent the support rod 4 from rotating too fast and causing impact and damage to the connecting components. The second guide rod 11 provides support for the first guide rod 10, enabling the first guide rod 10 to bear a greater load, making the items more stable during hoisting, improving the working efficiency of the device. The first guide rod 10 and the second guide rod 11 are fixed by bolts 8 to ensure the integrity of the device. By loosening the bolts 8, the first guide rod 10 and the second guide rod 11 droop and approach the support rod 4, folding and storing the device to reduce the occupied space during transportation and can be conveniently stored in the vehicle trunk.

[0032] Refer to Figure 1 , Figure 3 and Figure 3 , the lifting assembly includes a fixed block 5. The outside of the fixed block 5 is fixedly connected to the outside of the support rod 4. An activity slot 18 is opened inside the fixed block 5. A worm 17 is rotatably connected to the inner wall of the activity slot 18. A connecting rod 15 is rotatably connected to the inner wall of the fixed block 5. A worm gear 16 is fixedly connected to the outside of the connecting rod 15. A winding roller 20 is fixedly connected to the outside of the connecting rod 15. A cable 7 is sleeved on the outside of the winding roller 20. The outside of the worm 17 is meshed and connected to the outside of the worm gear 16. A transfer rod 19 is fixedly connected to the inside of the fixed block 5. The outside of the transfer rod 19 is slidably connected to the inside of the hook 13. A second rocker 6 is rotatably connected to the outside of the fixed block 5. One side of the second rocker 6 is fixedly connected to one end of the worm 17. The side of the winding roller 20 away from the worm gear 16 is rotatably connected to the inside of the fixed block 5.

[0033] Furthermore, the fixed block 5 serves as the housing of the lifting mechanism assembly, providing protection for the assembly. The connecting rod 15 can make the rotation of the worm gear 16 and the winding roller 20 more stable. At the same time, the worm gear 16 drives the winding roller 20 to rotate simultaneously through the connecting rod 15. By rotating the second rocker 6, the worm 17 is driven to rotate. The worm 17 drives the worm gear 16 to rotate simultaneously through meshing. Under the rotation of the worm gear 16, the winding roller 20 rotates to lift the cable 7. By manual operation, the device can adapt to field or powerless driving occasions, making the device more flexible to use. The function of the transfer rod 19 is to place the hook 13, making the device neater during storage. By the contact between one side of the winding roller 20 and the inside of the fixed block 5, the stability and reliability of the winding roller 20 are further increased.

[0034] Refer to Figure 1 , Figure 2 and Figure 4, the outer side of the bevel gear 21 meshes and connects with the outer side of the bevel gear 22. A rocker 3 is installed on the outer side of the mounting plate 2; Guide wheels 14 are installed on the outer sides of the connecting block 9 and the limiting member 12. One end of the cable 7 passes through the outer surfaces of the two guide wheels 14 in sequence; The inner side of the guide wheel 14 is slidably connected to the outside of the cable 7. One end of the cable 7 is fixedly connected to a hook 13, and the hook 13 is made of high-strength alloy steel.

[0035] Furthermore, the bevel gear 22 is driven to rotate by the rocker 3, and then the bevel gear 21 is driven to rotate simultaneously; The cable 7 is limited by the guide wheel 14 to increase the stability of the cable 7. At the same time, the guide wheel 14 can effectively reduce the wear between the cable 7 and the device, and at the same time make the cable 7 slide more smoothly. The hook 13 is used to lift items. It is made of high-strength alloy steel, which has excellent tensile strength and yield strength and can easily handle the task of lifting heavy objects.

[0036] Working principle: First, rotate the rocker 3, which drives the bevel gear 22 to rotate. Under the meshing action of the bevel gear 22, the bevel gear 21 and the support rod 4 rotate simultaneously, enabling the device to adjust the angle arbitrarily. Then loosen the bolt 8, and the guide rod 10 and the guide rod 11 fall naturally, completing the folding and storage of the device. Through the folding design, the device occupies a small space, making it more convenient for the vehicle to store and carry the device.

[0037] In addition, connect the hook 13 to the item to be lifted, and then manually rotate the rocker 2 6, driving the worm 17 to rotate synchronously. Then, the worm 17 drives the worm wheel 16 to rotate simultaneously through meshing. At this time, the worm wheel 16 drives the connecting rod 15 and the winding roller 20 to rotate simultaneously, winding the cable 7. The item is lifted by winding the cable 7. When the item is lifted to the required height, stop rotating the rocker 2 6 and fix the item in a suitable position. After use, separate the hook 13 from the item, and then rotate the rocker 2 6 to lower the cable 7. The heavy object is lifted through the manual lifting mechanism, with simple operation and no need for electric drive, suitable for various occasions, making the device more practical.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
