[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0021] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A trailer hook comprises a fixing seat 1, a sliding groove 2 is provided on the outer wall of the fixing seat 1, and a trailer hook body 3 is slidably connected to the inner wall of the sliding groove 2, a slider 4 is fixedly connected to the outer wall of the trailer hook body 3, a bolt hole 5 is provided on the inner wall of the fixing seat 1, a fixing bolt 6 is arranged on the inner wall of the trailer hook body 3, a threaded groove 7 is provided on the outer wall of the trailer hook body 3, a latch 8 is threadedly connected to the inner wall of the threaded groove 7, an external thread 9 is provided on the outer wall of the latch 8, a threaded hole 10 is provided on the outer wall of the latch 8, a threaded rod 11 is threadedly connected to the inner wall of the threaded hole 10, a reinforcing rib 12 is fixedly connected to the inner wall of the trailer hook body 3, and an installation hole 13 is provided on the outer wall of the fixing seat 1.

[0022] Through the above technical scheme, the utility model is provided with a mounting hole 13, which is convenient for the operator to fix the fixing seat 1 on the vehicle body with bolts. When the trailer hook body 3 is damaged, the trailer hook body 3 can be slid and removed from the fixing seat 1 by removing the fixing bolts 6, which is convenient for the operator to replace the trailer hook body 3. The operation is simple and meets people's needs. By providing a reinforcing rib 12, the strength of the trailer hook body 3 is enhanced and it is easy to use. The pin 8 is threadedly installed in the threaded groove 7 through the external thread 9, which enhances the connection effect and prevents the pin 8 from loosening and falling off. By providing a threaded rod 11 threadedly installed in the threaded hole 10 of the pin 8, the threaded rod 11 plays a limiting role to prevent the pin 8 from falling off.

[0023] Specifically, there are two sliders 4 , and the two sliders 4 are symmetrically arranged with the mid-perpendicular line of the trailer hook body 3 as the symmetry axis.

[0024] Through the above technical solution, by fixing two sliders 4 on the trailer hook body 3, the trailer hook body 3 can slide well in the slide groove 2 of the fixing seat 1 through the two sliders 4. During use, when the fixing bolt 6 is loosened, the fixing seat 1 can still be connected with the trailer hook body 3 through the slider 4, so as to effectively drive the trailer hook body 3 to move and pull the object. Thanks to the close fit between the slider 4 and the slide groove 2, the trailer hook body 3 can maintain normal operation even when the fixing bolt 6 is loose.

[0025] Specifically, the fixed seat 1 forms a sliding structure with the sliding block 4 through the sliding groove 2, and the inner wall of the sliding groove 2 fits with the outer wall of the sliding block 4.

[0026] Through the above technical solution, the connection effect between the fixing seat 1 and the slide groove 2 and the slider 4 is strengthened, which facilitates the sliding of the trailer hook body 3 in the slide groove 2 through the slider 4 and facilitates the sliding installation of the trailer hook body 3.

[0027] Specifically, the fixing seat 1 forms a fixing structure with the trailer hook body 3 through the fixing bolt 6, and one end of the fixing bolt 6 is threadedly passed through the trailer hook body 3 and extends into the bolt hole 5 for connection.

[0028] Through the above technical solution, the connection effect between the fixing seat 1 and the fixing bolts 6 and the trailer hook body 3 is strengthened. The number of the fixing bolts 6 is multiple, and the trailer hook body 3 can be well fixed in the fixing seat 1.

[0029] Specifically, the latch pin 8 forms a threaded structure with the thread groove 7 through the external thread 9, and one end of the latch pin 8 extends into the thread groove 7 for connection.

[0030] Through the above technical solution, the connection effect between the latch pin 8 and the external thread 9 and the thread groove 7 is strengthened, so that the latch pin 8 can be well threadedly installed in the thread groove 7 through the external thread 9, preventing the latch pin 8 from shaking during operation.

[0031] Specifically, the latch pin 8 forms a threaded structure with the threaded rod 11 through the threaded hole 10, and one end of the threaded rod 11 extends into the threaded hole 10 for connection.

[0032] Through the above technical scheme, the connection effect between the latch pin 8 and the threaded hole 10 and the threaded rod 11 is strengthened. By providing the threaded rod 11, the threaded rod 11 acts as a limit to prevent the latch pin 8 from falling off. By providing the threaded groove 7 and the threaded rod 11, two anti-falling methods are provided, which can effectively prevent the latch pin 8 from loosening and falling off, and facilitate use.

[0033] Specifically, the number of the mounting holes 13 is four, and two mounting holes 13 form a group. The two groups of mounting holes 13 are symmetrically arranged with the mid-perpendicular line of the fixing seat 1 as the symmetry axis.

[0034] Through the above technical solution, by providing four mounting holes 13, it is convenient for operators to fix the fixing seat 1 on the vehicle body using bolts, and welding can also be selected for fixing.

[0035] When in use, first of all, when installing, fix the fixing seat 1 on the vehicle body, slide the trailer hook body 3 into the slide groove 2, and fix the trailer hook body 3 on the fixing seat 1 by using the fixing bolt 6; when in use, install the trailer rope in the trailer hook body 3, and thread the pin 8 into the thread groove 7, so that one end of the pin 8 passes through the rope and extends out of the bottom of the trailer hook body 3, and thread the threaded rod 11 into the pin 8 to limit it and prevent the pin 8 from falling off. When the trailer hook body 3 is damaged and needs to be replaced, the fixing bolt 6 is removed, and the trailer hook body 3 can be slid and removed from the fixing seat 1, and the operator can replace the spare trailer hook body 3, which completes all the work. The content not described in detail in this manual belongs to the prior art known to professional and technical personnel in this field.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the invention is defined by the appended claims and their equivalents.
