Description

Technical Field

[0001] The utility model relates to the technical field of trailer equipment, in particular to a portable trailer hook device. Background Art

[0002] With the steady development of social economy, the number of family cars has increased year by year, and self-driving tours have become a leisure choice for more and more people. In order to ensure that family cars may get stuck in muddy roads and slip during the tour, many family cars are equipped with convenient trailer hooks. Once the family car gets into trouble, it can be connected to the towing vehicle through the trailer hook for pulling and rescue, thus ensuring the smooth progress of the self-driving tour.

[0003] Currently, the portable trailer hooks on the market are mainly composed of a trailer rope and two trailer hooks. However, when not in use, the trailer rope is easy to form a knot due to its long length. This phenomenon causes inconvenience when using the trailer hook again. The owner needs to spend extra time and effort to untie the knot, which to some extent affects the convenience of using the portable trailer hook.

[0004] Therefore, we propose a portable trailer hook device to solve the above problems. Utility Model Content

[0014] 1. The portable trailer hook device is provided with an anti-loosening mechanism, a trailer rope, a trailer hook and a metal cover. When a vehicle is towed by the trailer hook and the trailer rope, the limit plate is first moved close to the trailer hook, and the nut is rotated on the connecting thread and the limit plate is squeezed so that the limit plate seals the opening of the trailer hook to prevent the trailer hook from falling off and causing failure of towing the trailer. The metal cover is in the middle position of the trailer rope, and the weight of the metal cover and the rotating column can ensure that the trailer rope will not return to hit the surface of personnel and vehicles in the event of an accidental break, thereby ensuring the safety of the towing process. The mechanism enables the trailer hook to have an anti-unhooking function, thereby improving the reliability of the use of the trailer hook, and also has the ability to prevent the broken trailer rope from returning to hit the vehicle and personnel, thereby improving the reliability of the use of the trailer hook.

[0015] 2. The portable trailer hook device is provided with a rotating handle, a rotating column and a metal cover. When the trailer hook is used, the rotating column is rotated by rotating the handle. The rotating rotating column drives the trailer rope to be wound and recovered, and is placed inside the metal cover. The friction force of the rubber block and the rubber limiting ring can ensure that the trailer rope is stable after recovery and is not easy to loosen. Finally, it can be conveniently carried through the U-shaped carrying handle. In addition, the trailer rope of the trailer hook is not easy to get tangled, ensuring that the trailer hook is easy to use again. This mechanism enables the portable trailer hook to have the function of convenient recovery. At the same time, the trailer rope is not easy to get tangled, and the convenience of reusing the trailer hook can be improved.

[0016] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The utility model enables the portable trailer hook to have the function of convenient recovery. At the same time, the trailer rope is not easy to get tangled, and the convenience of reusing the trailer hook can be improved. The trailer hook also has an anti-unhooking function, which improves the reliability of the use of the trailer hook. At the same time, it can prevent the broken trailer rope from returning to hit vehicles and personnel, thereby improving the reliability of the use of the trailer hook.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A portable trailer hook device comprises two metal covers 1, the outer walls of the two metal covers 1 are fixedly connected to each other, the outer walls of the two metal covers 1 are provided with through holes, and rolling bearings 2 are fixedly connected to the hole walls of the through holes, a rotating column 3 is fixedly connected to the inner walls of the inner rings of the two rolling bearings 2, the outer end of the rotating column 3 is fixedly connected to a rotating handle 8, the outer surface of the rotating handle 8 is fixedly connected to a rubber block 10, the outer wall of the rubber block 10 is in frictional contact with the outer wall of the metal cover 1, and the rotating handle 8 can easily rotate the rotating column 3, the outer wall of the rotating column 3 is provided with three connecting holes 4, the hole walls of the three connecting holes 4 are commonly connected with a towing rope 5, the two ends of the towing rope 5 respectively pass through the outer walls of the two metal covers 1, the two ends of the towing rope 5 are fixedly connected to connecting rings 6, and the outer wall of the connecting ring 6 is fixedly connected to a trailer hook 7.

[0023] The outer wall of the trailer hook 7 is sleeved with an anti-loosening mechanism 9, and the anti-loosening mechanism 9 includes a limit plate 91 and a nut 92 sleeved with the outer wall of the trailer hook 7. The outer wall of the limit plate 91 is provided with a limit groove 11 that matches the side end of the trailer hook 7. The limit groove 11 can increase the contact area between the limit plate 91 and the trailer hook 7 to ensure the sealing effect of the trailer hook 7. The rod wall of the trailer hook 7 is provided with a connecting thread 93 that matches the inner wall of the nut 92. This mechanism enables the trailer hook to also have the function of preventing unhooking, thereby improving the reliability of the use of the trailer hook.

[0024] A U-shaped carrying handle 12 is fixedly connected to the outer wall of one of the metal outer covers 1, and the U-shaped carrying handle 12 can facilitate carrying the trailer hook. The outer walls of the two metal outer covers 1 are provided with through holes that match the tow rope 5, and the hole walls of the through holes are fixedly connected to rubber limiting rings 13. The friction force of the rubber limiting rings 13 can prevent the tow rope 5 from loosening after being recovered.

[0025] In the utility model, when the vehicle is towed by the trailer hook 7 and the towing rope 5, the limiting plate 91 is first moved close to the trailer hook 7, and the nut 92 is rotated on the connecting thread 93, and the limiting plate 91 is squeezed, so that the limiting plate 91 seals the opening of the trailer hook 7, thereby preventing the trailer hook 7 from falling off and causing the failure of towing the trailer. In addition, the metal cover 1 is in the middle position of the towing rope 5, and the weight of the metal cover 1 and the rotating column 3 can ensure that the towing rope 5 will not return to hit the surface of personnel and the vehicle in the event of an accidental break, thereby ensuring the safety of the towing process. This mechanism enables the trailer hook to have an anti-unhooking function, thereby improving the reliability of the use of the trailer hook, and also has an anti-breaking towing function. The vehicle rope 5 has the ability to return and hit vehicles and personnel, thereby improving the reliability of the use of the trailer hook. When the trailer hook is used up, the rotating column 3 is rotated by rotating the handle 8. The rotating rotating column 3 drives the trailer rope 5 to be wound and recovered, and is placed inside the metal outer cover 1. The friction force of the rubber block 10 and the rubber limiting ring 13 can ensure that the trailer rope 5 is stable after recovery and is not easy to loosen. Finally, it can be conveniently carried through the U-shaped carrying handle 12. In addition, the trailer rope 5 of the trailer hook is not easy to get tangled, thereby ensuring that the trailer hook is convenient to use again. This mechanism enables the portable trailer hook to have the function of convenient recovery. At the same time, the trailer rope 5 is not easy to get tangled, and the convenience of reusing the trailer hook can be improved.
