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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-5 A trailer component for a vehicle rescue trailer, comprising a trailer hook 1, a mounting mechanism 2 and a locking mechanism 3; wherein the mounting mechanism 2 comprises a mounting seat 201 fixed on a vehicle frame, a mounting frame 202 rotatably mounted on one side of the mounting seat 201 and a rotating structure rotatably mounted on the mounting frame 202, and an adjusting member connected to the trailer hook 1 is provided on the rotating structure; it should be noted that a first fastening bolt 203 for fixing the mounting frame 202 is installed inside the mounting seat 201. The mounting frame 202 is L-shaped in shape, and the mounting frame 202 is composed of two telescopically connected plates, and a second fastening bolt 204 is installed on the internal thread of the mounting frame 202.

[0031] Specifically, the rotating structure includes a connecting shaft 209 rotatably installed inside the mounting frame 202, and the interior of the connecting shaft 209 passes through the interior of the mounting frame 202, and the upper and lower ends of the connecting shaft 209 are respectively fixed with a rotating sleeve 208 and a chuck 210, and the top of the rotating sleeve 208 is welded with a support platform 205.

[0032] In order to improve the flexibility of the trailer hook 1, the adjustment member includes a rotating screw sleeve 206 rotatably mounted on the outer surface of the support platform 205 and a screw rod 207 threadedly inserted into the rotating screw sleeve 206, one end of the screw rod 207 extends into the support platform 205, and the other end thereof is threadedly fixed to the outer surface of the trailer hook 1. Through the threaded cooperation of the rotating screw sleeve 206 and the screw rod 207, the position of the trailer hook 1 relative to the support platform 205 can be easily adjusted. This design allows rescuers to quickly and accurately adjust the length and angle of the trailer hook 1 according to actual needs to adapt to trapped vehicles of different sizes and types.

[0033] In addition, since the trailer hook 1 can be flexibly adjusted by rotating the screw sleeve 206 and the screw rod 207, the trailer component can be applied to more types of rescue scenarios. Whether it is a small car or a large truck, the rescuer can adjust the position and angle of the trailer hook 1 according to the actual situation to ensure the safety and effectiveness of the rescue process.

[0034] It is worth mentioning that traditional trailer components may require complex operating steps to adjust the position and angle of the trailer hook. However, this design can achieve flexible adjustment of the trailer hook through a simple rotation operation, which greatly simplifies the operation process and reduces the difficulty of operation. The design structure of the trailer component is relatively simple, and the connection between the various components is firm and reliable. This design makes the trailer component easy to maintain and maintain in daily use, reducing maintenance costs and time. The trailer hook 1 can be folded by the first fastening bolt 203, and then the trailer hook 1 can be placed inside the rear of the vehicle to prevent the trailer hook 1 from exceeding the rear of the vehicle when not in use, which is illegal.

[0035] like Figure 2-Figure 5 As shown, the locking mechanism 3 includes a swing frame 301 installed on the outside of the mounting frame 202, a connecting frame 302 and an electric telescopic rod 303, the locking mechanism 3 also includes a gear 305, a tooth plate 307, a mounting block 309 fixed to the outer surface of the tooth plate 307 and a locking rod 310 fixed to the inside of the mounting block 309 and connected to the rotating structure, a linkage is provided between the swing frame 301 and the gear 305, and the gear 305 is meshed with the tooth plate 307.

[0036] Specifically, the connecting frame 302 is bolted to the outer surface of the mounting frame 202, the middle outer surface of the swing frame 301 is hingedly mounted on the inner side of the connecting frame 302, and the electric telescopic rod 303 is hingedly mounted between the swing frame 301 and the mounting frame 202. Among them, a clamping block 304 is welded on the top outer surface of the swing frame 301, and a plurality of first clamping holes 2081 arranged at equal intervals are opened inside the rotating sleeve 208. The swing frame 301 is extended and retracted by the electric telescopic rod 303 and rotated by the support of the connecting frame 302, so that the clamping block 304 is clamped with the first clamping hole 2081.

[0037] In this embodiment, three limit frames 313 are fixed to the lower surface of the mounting frame 202, wherein two limit frames 313 are symmetrically arranged, the tooth plate 307 slides through the two limit frames 313 arranged oppositely, and a connecting rod 306 rotatably connected to the other limit frame 313 is fixed inside the gear 305. A stopper 308 is fixed to the outer surface of one end of the tooth plate 307 close to the mounting block 309, and a buffer spring 314 surrounding the outer surface of the tooth plate 307 is fixed to the outer surface of the stopper 308, and the buffer spring 314 is fixed to the outer surface of one of the limit frames 313 arranged oppositely.

[0038] In order to improve the locking effect of the locking mechanism 3, the linkage includes a push rod 311 and a connecting arm 312. The push rod 311 and the connecting arm 312 are hinged at opposite ends. The end of the push rod 311 away from the connecting arm 312 is hinged to the bottom side of the swing frame 301, and the top side of the connecting arm 312 is fixed to the end of the connecting rod 306. It should be noted that a plurality of second clamping holes 2101 arranged equidistantly are provided inside the chuck 210, and the locking rod 310 is inserted, and the plurality of second clamping holes 2101 are arranged in a ring. The swing frame 301 is driven to rotate by the telescopic movement of the electric telescopic rod 303, so that the clamping block 304 is clamped with the first clamping hole 2081, thereby realizing the preliminary fixation of the trailer hook and its connecting structure. This mechanical locking method is stable and reliable, and can effectively prevent the trailer hook from accidentally falling off during towing, thereby improving the safety of rescue operations. In addition, the meshing design of the gear 305 and the tooth plate 307, and the linkage formed by the push rod 311 and the connecting arm 312 enable the locking rod 310 to move with the rotation of the swing frame 301, and then be plugged into or disengaged from the second clamping hole 2101. This design not only realizes multiple locking of the trailer hook, but also improves the flexibility of the locking mechanism, so that the trailer hook can be firmly locked in different positions and directions.

[0039] The working principle of the above embodiment is:

[0040] First, the mounting seat 201 is fixed to the vehicle frame, and the mounting frame 202 is fixed to the mounting seat 201 by the first fastening bolt 203. The mounting frame 202 is composed of two telescopically connected plates. By adjusting and fastening the second fastening bolt 204, the length of the mounting frame 202 can be adjusted to meet different installation requirements of the trailer hook 1. At the same time, the first fastening bolt 203 can be used to rotate the trailer hook 1 and move it out of the vehicle, so as to use it as a rescue trailer.

[0041] When in use, the length of the trailer hook 1 can be adjusted by rotating the screw sleeve 206 and the threaded cooperation of the screw rod 207 to enhance the flexibility of the trailer hook 1. Then, the swing frame 301 is rotated by extending and retracting the electric telescopic rod 303. At this time, the block 304 on the locking mechanism 3 is disengaged from the connection with the first clamping hole 2081. When the swing frame 301 rotates, the push rod 311 hinged on its bottom side drives the gear 305 to rotate through the connecting arm 312. The gear 305 rotates and engages with the tooth plate 307 to drive the locking rod 310 to move, so that the locking rod 310 is disengaged from the connection with the second clamping hole 2101, and then the trailer hook 1 can be adjusted for horizontal rotation, further improving the adjustment flexibility of the trailer hook 1 so as to adapt to rescue needs with different needs.
