[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 、 2 Figures 1, 2, 3, and 4. In the embodiment of the present invention, a trailer hitch latching structure includes a longitudinal beam 1 of the vehicle body. A second fixed plate 201 is provided on one side of the longitudinal beam 1 of the vehicle body. Slide grooves 203 are provided at the bottoms of both ends on the outside of the second fixed plate 201. A fixed ring 3 is provided in the middle of the slide groove 203. During the process of pulling the trailer rope, the ring 301 will change at different angles through the spherical beads 303, making the force received by the trailer rope more uniform. A ring 301 is provided inside the fixed ring 3. When pulling the trailer rope, the bolts near the trailer hitch will be affected at the moment of pulling. By passing the trailer rope through the ring 301, first grooves 302 are provided on the inner wall of the fixed ring 3 and the outside of the ring 301. Spherical beads 303 are provided inside the first grooves 302. A slide block 304 is provided on the outside of the fixed ring 3. The slide block 304 is slidably connected to the inside of the slide groove 203. An end of the slide block 304 is fixed with a telescopic rod 306. A spring 305 is provided on the outside of the telescopic rod 306. The trailer rope will pull the ring 301 and the fixed ring 3 to slide to one side through the slide block 304. The slide block 304 slides to one side and is buffered by the 306 and the spring 305. A support plate 101 is provided at the bottom of the longitudinal beam 1 of the vehicle body;

[0022] The end of the telescopic rod 306 is fixedly connected to the inner wall of the first groove 302, the end of the spring 305 is fixedly connected to the inner wall, a rotating ring 4 is rotatably connected to one side of the slider 304, and a plurality of rotating columns 401 are rotatably connected inside the rotating ring 4. When the towing rope passes through the ring 301, the outer side of the towing rope contacts the outer side of the rotating column 401. When the towing rope moves, the rotating column 401 will rotate, reducing the wear of the towing rope. An arc-shaped plate 402 is arranged at the end inside the rotating ring 4. A first fixing plate 101 is arranged at the top of the vehicle body longitudinal beam 1. One side of the bottom of the first fixing plate 101 is fixedly connected with a third fixing plate 202, and the other side of the bottom of the first fixing plate 101 is fixedly connected with the top of the second fixing plate 201. The first fixing plate 101, the second fixing plate 201, the third fixing plate 202, and the support plate 101 are all fixed to the outside of the vehicle body longitudinal beam 1 by bolts.

[0023] Working principle: When the towing rope is pulled, the bolts near the towing hook will be affected at the moment of pulling. By passing the towing rope through the ring 301, the towing rope will pull the ring 301 and the fixed ring 3 to slide to one side through the slider 304. The slider 304 slides to one side and is buffered by 306 and the spring 305 to prevent the bolts near the towing hook from being affected by the momentary pulling force.

[0024] During the process of pulling the towing rope, the ring 301 will change at different angles through the ball 303, making the force received by the towing rope more uniform. When the towing rope passes through the ring 301, the outer side of the towing rope contacts the outer side of the rotating column 401. When the towing rope moves, the rotating column 401 will rotate, reducing the wear of the towing rope.

[0025] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
