Description

Technical Field

[0001] This utility model relates to the field of trailer hitch technology, specifically a new type of high-performance trailer hitch. Background Technology

[0002] The main function of a trailer hitch is to tow and pull vehicles. It can be used to tow disabled vehicles when they are unable to move, by connecting a tow rope or tow bar to a safe location or repair shop. It can also tow other vehicles in special situations, such as when a vehicle is stuck in mud, snow, or other difficult conditions and cannot move on its own. Furthermore, it can be used to tow caravans or trailers. For drivers who enjoy road trips, trailer hitches can be used to tow caravans, trailers, or other vehicles, increasing cargo space and travel convenience. Additionally, trailer hitches facilitate rescue efforts for other vehicles, improving rescue efficiency.

[0003] When in use, a trailer hitch attaches to a trailer at one end and a tow rope at the other, connecting the towing and towed vehicles together. However, existing trailer hitches have flawed safety buckle designs. The safety buckle only serves to prevent the tow rope from detaching from the hitch, and may break under heavy pulling. Therefore, we provide a new type of high-performance trailer hitch to solve these problems. Utility Model Content

[0025] 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.

[0026] like Figure 1-5As shown, this utility model provides a technical solution: a novel high-performance trailer hook, including a trailer hook body 1 and a safety buckle 2. The trailer hook is S-shaped. One end of the safety buckle 2 is connected to a slide block 3. A slider 4 is slidably connected to the inner wall of the slide block 3. Multiple sets of first springs 5 ​​are provided on the outside of the slider 4. A support shaft 6 is connected to one side of the trailer hook body 1. The inner wall of the slider 4 is rotatably connected to the outer surface of the support shaft 6. Both ends of the trailer hook body 1 can be used to attach a trailer rope. There are two safety buckles 2, which are located on both sides of the trailer hook body 1. The slide block 3 moves through the slider 4 and supports the safety buckle 2 through the support shaft 6, so that the safety buckle 2 has a rotation function. The safety buckle 2 opens and closes the trailer hook body 1 by rotating.

[0027] A support block 8 is connected to the outer surface of the trailer hook, and a stop block 9 is also connected to the outer surface of the trailer hook body 1. A support groove 10 is provided on the inner side of the safety buckle 2, and the diameter of the support groove 10 is larger than that of the support block 8. The support block 8 is located inside the support groove 10. The support groove 10 is larger than the support block 8 to allow the safety buckle 2 to move, so that the safety buckle 2 has space to move. When the safety buckle 2 rotates downward and remains horizontal with the trailer hook body 1, there is a positional difference between the safety buckle 2 and the trailer hook body 1. The space inside the slide 3 and the space of the support groove 10 being larger than that of the support block 8 provide space for the safety buckle 2 to move. A stop groove 11 is provided on the inner side of the safety buckle 2. The inner wall of the stop groove 11 contacts the outer surface of the stop block 9. The safety buckle 2 contacts the support block 8 through the support groove 10, providing support force to one end of the safety buckle 2. The stop block 9 provides resistance to the safety buckle 2. The safety buckle 2 contacts the stop block 9 through the stop groove 11 and receives the resistance of the stop block 9.

[0028] The inner wall of the slide block 3 is connected to multiple sets of guide rods 12. The outer surfaces of the multiple guide rods 12 are slidably connected to the inner wall of the slider 4. The guide rods 12 provide support force to the slider 4 to maintain the stability of the slider 4 when it moves. At the same time, the guide rods 12 provide support force to the first spring 5 to maintain the stability of the first spring 5 when it elastically contracts.

[0029] Multiple sets of first springs 5 ​​are sleeved on the outside of multiple sets of guide rods 12. One end of each set of first springs 5 ​​is connected to one side of the slider 4, and the other end of each set of first springs 5 ​​is connected to the inner wall of the slide block 3. The first springs 5 ​​are located on the left and right sides of the slider 4 respectively. The first springs 5 ​​provide elastic support force to the left and right sides of the slider 4, and provide reset power to the slider 4 after the slider 4 moves to a new position.

[0030] The slider 4 is provided with a positioning mechanism 7 on its outside. The positioning mechanism 7 provides resistance to the safety buckle 2 and maintains the stability of the safety buckle 2. The positioning mechanism 7 includes a toothed disc 701. One side of the toothed disc 701 is connected to one side of the slider 4. The outer surface of the toothed disc 701 is in contact with a toothed disc 702. The inner wall of the toothed disc 702 is slidably connected to the outer surface of the support shaft 6. The outer surfaces of the first toothed disc and the toothed disc 702 are both protrusions with an inclined angle. Through the misalignment between the protrusions, the toothed disc 701 and the toothed disc 702 provide resistance to each other.

[0031] A support disc 703 is connected to the end of the support shaft 6 away from the trailer hook body 1. Multiple support rods 704 are slidably connected to the inner wall of the support disc 703 in a circular array. One end of each support rod 704 is connected to the other side of the gear disc 702. A limit block 705 is connected to the end of each support rod 704 outside the support disc 703. The support disc 703 and the support rods 704 provide support for the second spring 706, maintaining the stability of the second spring 706 during elastic contraction. The support rod 704 provides support and guidance for the second gear 702, guiding the movement direction of the second gear 702 so that the second gear 702 only has the function of moving back and forth, preventing the second gear 702 from rotating. A second spring 706 is sleeved on the outside of the support rod 704. One end of the second spring 706 is connected to one side of the support plate 703, and the other end of the second spring 706 is connected to the other side of the second gear 702. The second spring 706 provides an elastic pushing force to the second gear 702, pushing the second gear 702 to maintain a tight contact force with the first gear 701.

[0032] Working principle: In use, the tow rope is first hung inside the trailer hook body 1. The safety buckle 2 is rotated to be flush with the trailer hook body 1. At the same time, the support groove 10 is engaged with the outside of the support block 8, and the stop groove 11 is in contact with the outer surface of the stop block 9. The safety buckle 2 and the trailer hook body 1 are connected into a whole through the support groove 10 and the stop groove 11, which improves the overall strength of the trailer hook body 1. When the safety buckle 2 rotates, it drives the gear disc 701 to rotate at the same time. After the gear disc 701 rotates, it pushes the gear disc 702 to move towards the support plate 703. When the gear disc 702 moves, it compresses the second spring 706. After the safety buckle 2 stops rotating, the second spring 706 pushes the gear disc 702 to make it tightly contact the gear disc 701, providing resistance to the gear disc 701. The gear disc 701 transmits the resistance to the slider 4.
