[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: an automobile towing structure, including a towing rod 1 and a fixed sleeve 2. A towing hole 3 is opened on the left side surface of the fixed sleeve 2. A limit block 4 adapted to the towing hole 3 is fixedly connected to the right side surface of the towing rod 1. Four groups of card slots 5 are opened on the outer surface of the right side of the towing rod 1. Four groups of rectangular holes 6 corresponding to the four groups of card slots 5 are opened on the inner wall of the towing hole 3. A locking component is installed on the inner wall of each group of rectangular holes 6. The locking component includes a fixed shaft 7 fixedly installed on the inner side wall of the inner side of the rectangular hole 6 and a locking block 8 slidably connected to the rectangular hole 6. The inner side surface of the locking block 8 is an inclined surface. The fixed shaft 7 is movably inserted into the locking block 8. A limit hole 9 with a center line coinciding with the center line of the fixed shaft 7 is opened on the inner side surface of each group of locking blocks 8. A limit plate 10 is fixedly connected to the inner side surface of each group of fixed shafts 7. A locking spring 11 with an inner end and an outer end respectively fixedly connected to the outer side surface of the locking block 8 and the inner side wall of the rectangular hole 6 is sleeved on the outer surface of each group of fixed shafts 7. Four groups of slide grooves 12 are opened in the middle of the outer surface of the towing rod 1. A slide block 13 is slidably connected to the inside of each group of slide grooves 12. A moving cylinder 14 with an outer diameter equal to the outer diameter of the limit block 4 is fixedly sleeved on the outer surfaces of the four groups of slide blocks 13. A return component is installed on the outer surface of the towing rod 1. The return component includes a fixed ring 16 fixedly sleeved on the left end of the towing rod 1 and a moving ring 15 fixedly installed on the left side surface of the moving cylinder 14. A return spring 17 fixedly connected to the right side surface and movably sleeved on the outer surface of the towing rod 1 and with a right end fixedly connected to the left side surface of the moving ring 15 is provided.

[0025] In the present utility model, in order to enable the moving cylinder 14 to move smoothly, the inner diameter of the moving cylinder 14 is set to be 1.05 times the outer diameter of the traction rod 1. The four groups of sliders 13 are annularly arrayed with the center line of the moving cylinder 14 as the center. This not only enables the four groups of sliders 13 to evenly bear the moving cylinder 14, but also enables the moving cylinder 14 and the traction rod 1 to have no contact, thereby effectively improving the smoothness of the movement of the moving cylinder 14.

[0026] In the present utility model, in order to enable the limit block 4 to be inserted into the traction hole 3 conveniently, the outer diameter of the limit block 4 is set to be 19 / 20 of the inner diameter of the traction hole 3. The edge of the right side surface of the limit block 4 is chamfered. The outer diameter of the limit block 4 is 1.2 times the outer diameter of the traction rod 1. This enables the limit block 4 to be inserted into the traction hole 3 conveniently and flexibly, effectively improving the convenience of the connection between the limit block 4 and the traction hole 3.

[0027] In the present utility model, in order to enable the limit plate 10 to limit the locking block 8 smoothly, the material of the limit plate 10 is set to stainless steel, thereby improving the service life of the limit plate 10. And the outer diameter of the limit plate 10 is set to be smaller than the inner diameter of the limit hole 9, and the center line of the limit plate 10 coincides with the center line of the limit hole 9, so that there is no friction between the limit plate 10 and the limit hole 9, effectively improving the smoothness of the limit of the locking block 8 by the limit plate 10.

[0028] The electrical components appearing in this text are all electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0029] The working principle of the present utility model is as follows:

[0030] S1. Install the traction rod 1, align the limit block 4 with the traction hole 3, and align the four groups of card slots 5 with the four groups of locking blocks 8. Let the limit block 4 drive the traction rod 1 to insert into the traction hole 3. The back surface of the limit block 4 presses the four groups of locking blocks 8. Since the inner side surface of the locking block 8 is an inclined surface, the locking block 8 can move outward relative to the rectangular hole 6 and the fixed shaft 7. At this time, the locking spring 11 is compressed. The front surface of the limit block 4 passes over the locking block 8 and the traction rod 1 continues to move to the right. When the locking block 8 is aligned with the card slot 5, under the elastic action of the locking spring 11, the locking block 8 can move inward relative to the fixed shaft 7 and the rectangular hole 6, so that the locking block 8 is adapted to the card slot 5 to lock the traction rod 1. Thus, the installation of the traction rod 1 is completed;

[0031] S2. Unlock the towing rod 1. Hold the moving cylinder 14 and make the moving cylinder 14 drive the four groups of sliders 13 and a group of moving rings 15 to move to the right along the trajectories of the four groups of chutes 12. At this time, the return spring 17 is stretched. When the right side of the moving cylinder 14 contacts the locking block 8, the moving cylinder 14 squeezes the four groups of locking blocks 8, so that the locking blocks 8 can still move outward and separate from the card slots 5. After the locking blocks 8 are separated from the card slots 5, the moving cylinder 14 continues to move to the right until the right side of the moving cylinder 14 contacts the left side of the limit block 4. Since the outer diameter of the moving cylinder 14 is the same as that of the limit block 4, when pulling the towing rod 1, the moving cylinder 14 and the limit block 4 to the left, the locking blocks 8 will not hinder the movement of the limit block 4, and the limit block 4 can be directly and conveniently removed, thus unlocking the towing rod 1. Under the elastic action of the return spring 17, the moving ring 15 drives the moving cylinder 14 and the sliders 13 to return to their original positions, so that the moving cylinder 14 will not hinder the reinstallation of the limit block 4. When the towing rod 1 and the limit block 4 leave the fixed sleeve 2, the locking blocks 8 move inward under the action of the locking spring 11. Under the action of the limit plate 10 and the fixed shaft 7, the locking blocks 8 will not move inward excessively. Therefore, when reinstalling the limit block 4 and the towing rod 1, the limit block 4 can still squeeze the inner side of the locking blocks 8, and thus the towing rod 1 can be locked conveniently again.

[0032] In summary, for this vehicle towing structure, by directly making the limit block 4 drive the towing rod 1 to move and inserting the limit block 4 directly into the towing hole 3, the limit block 4 can conveniently squeeze the four groups of locking blocks 8. And under the action of the fixed shaft 7, the locking blocks 8 can move outward conveniently and smoothly. When the card slots 5 are aligned with the locking blocks 8, the locking blocks 8 can flexibly fit with the card slots 5 to lock the towing rod 1, greatly improving the convenience of installing the towing rod 1 and reducing the difficulty of connecting the towing rod 1. By setting the moving cylinder 14 to drive the four groups of sliders 13 to move horizontally to the right along the trajectories of the chutes 12 at the same time, the moving cylinder 14 can squeeze the four groups of locking blocks 8 at the same time, so that the four groups of locking blocks 8 can unlock the towing rod 1 at the same time. And the outer diameter of the moving cylinder 14 is the same as that of the limit block 4, so when pulling out the limit block 4, the locking blocks 8 will not hinder the movement of the limit block 4, greatly improving the convenience of disassembling and assembling the towing rod 1. By setting the return spring 17 to always apply a leftward force to the moving ring 15, after the towing rod 1 is disassembled, only by loosening the moving cylinder 14, the moving cylinder 14 can return to its original position conveniently, so that the moving cylinder 14 will not hinder the installation of the towing rod 1. By setting the fixed shaft 7 and the limit plate 10 to limit the locking blocks 8, after the towing rod 1 is separated from the towing hole 3, the locking blocks 8 will not move inward excessively. When reinstalling the towing rod 1, the limit block 4 can still conveniently squeeze the locking blocks 8, thus greatly improving the practicability of the towing structure.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.

[0034] The above has made a detailed description of the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can also be made without departing from the gist of this patent.
