Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 , an embodiment provided by the utility model: a trailer hook reinforcement structure, including a front end fixing plate 1, a rear end fixing plate 2, a hexagonal bolt 3, a movable connecting piece 5 and a trailer hook ring 6, a tension dispersing connecting plate 4 is fixedly connected to the middle of one side of the front end fixing plate 1, a fixed connecting piece 10 is fixedly connected to the middle of one side of the tension dispersing connecting plate 4 away from the front end fixing plate 1, a reinforcing triangular plate 7 is fixedly connected to the middle of one side of the rear end fixing plate 2, the reinforcing triangular plate 7 can strengthen the strength of the rear end fixing plate 2, the reinforcing triangular plate 7 can disperse the local tension or pressure on the rear end fixing plate 2 to a larger area, thereby reducing the internal stress of the rear end fixing plate 2 caused by the force, reducing the possibility of cracks, and the rear end fixing plate 2 away from the reinforcing triangular plate 7. An anti-skid strip 9 is evenly fixed on one side of the strong triangle plate 7. The anti-skid strip 9 is used to increase the friction between the rear end fixing plate 2 and the anti-collision beam, which greatly reduces the probability of movement or shaking during towing and improves the safety of trailer operation. A first fixing hole 13 is evenly penetrated on the front end fixing plate 1, and a second fixing hole 14 is evenly penetrated on the rear end fixing plate 2. A hexagonal clamping groove 8 is evenly opened on the side of the rear end fixing plate 2 close to the strengthened triangle plate 7. The threaded end of the hexagonal bolt 3 is threadedly connected with a hexagonal nut 12, and a connecting shaft pin 11 is movably inserted on the fixed connector 10. The rear end fixing plate 2 is located on the side of the front end fixing plate 1 away from the tension dispersion connecting plate 4, and the anti-skid strip 9 is located on the side of the rear end fixing plate 2 close to the front end fixing plate 1.

[0020] The hexagonal snap-in groove 8 is located at an end of the second fixing hole 14 away from the front end fixing plate 1, and the hexagonal snap-in groove 8 is connected to the second fixing hole 14. The hexagonal snap-in groove 8 matches one end of the hexagonal head of the hexagonal bolt 3. The hexagonal bolt 3 is movably inserted into the inner sides of the first fixing hole 13 and the second fixing hole 14 respectively. The hexagonal head of the hexagonal bolt 3 can be limited by the hexagonal snap-in groove 8. When installing the hexagonal nut 12, there is no need to fix the hexagonal bolt 3, thereby reducing the difficulty of installation.

[0021] The movable connector 5 is movably inserted in one end of the fixed connector 10 away from the tension dispersion connecting plate 4, and the connecting axle pin 11 is movably inserted in the inner sides of the movable connector 5 and the fixed connector 10 respectively. The trailer hook 6 is fixedly connected to the middle part of one end of the movable connector 5 away from the fixed connector 10. The movable connector 5 and the fixed connector 10 are movably connected by the connecting axle pin 11 to carry out trailer work. The movable connector 5 can be disassembled and stored when not in use.

[0022] The two ends of the central protrusion of the tension dispersing connecting plate 4 are in a trapezoidal design that is beveled toward the front fixed plate 1. The trapezoidal design of the tension dispersing connecting plate 4 can distribute the tension transmitted by the fixed connector 10 on the front fixed plate 1, thereby reducing local stress and improving overall strength.

[0023] Working principle: During use, first select the front end fixing plate 1 and the rear end fixing plate 2 that are suitable for the length of the anti-collision beam according to the effective installation length of the rear end anti-collision beam of the vehicle, that is, the length that can be installed for the front end fixing plate 1 and the rear end fixing plate 2 without affecting the effect of the anti-collision beam, and place the side of the rear end fixing plate 2 close to the anti-slip strip 9 on the inner middle part of the anti-collision beam at the rear end of the vehicle through external force, and place the side of the front end fixing plate 1 away from the tension distribution connecting plate 4 on the outer middle part of the anti-collision beam, and then insert the hexagonal bolt 3 into the second fixing hole 14 and the first fixing hole 13 in turn through external force, and insert the hexagonal head of the hexagonal bolt 3 into the inner side of the hexagonal clamping groove 8, and then use a wrench to install the hexagonal nut 12 on the threaded end of the hexagonal bolt 3 to fix the front end fixing plate 1 and the rear end fixing plate 2 at both ends of the anti-collision beam. At this time, the anti-collision beam is sandwiched between the front end fixing plate 1 and the rear end fixing plate 2, and then connected through the connecting shaft. The pin 11 installs the movable connecting piece 5 on the fixed connecting piece 10 to complete the assembly. When the towing work starts, the towing rope is fixed to the towing hook ring 6 for towing. During the towing process, the towing rope transfers the tension to the movable connecting piece 5, and the movable connecting piece 5 transfers the tension to the fixed connecting piece 10 through the connecting shaft pin 11. The fixed connecting piece 10 disperses the tension to the front end fixed plate 1 through the tension dispersing connecting plate 4, and the front end fixed plate 1 disperses the tension to the rear end fixed plate 2 through the hexagonal bolt 3. Since the anti-collision beam is sandwiched between the front end fixed plate 1 and the rear end fixed plate 2, all the tension is concentrated on the effective installation length of the anti-collision beam and transmitted to the vehicle main frame. The strength of the rear end fixed plate 2 is strengthened by strengthening the triangle plate 7 to avoid the rear end fixed plate 2 from breaking. The friction between the rear end fixed plate 2 and the anti-collision beam is strengthened by the anti-slip strip 9 to avoid shaking during towing that affects the safety of the towing process.
