Description

Technical Field

[0001] The utility model relates to a trailer hook installation structure, in particular to a detachable trailer hook installation structure. Background Art

[0002] Due to improper daily maintenance or various malfunctions, some cars may occasionally break down during normal use. When a car breaks down, the setting of the car's trailer hook plays a vital role in the rescue of the vehicle. The car trailer hook is an important component for the rescue of the car with the help of other vehicles and tow ropes. During use, the trailer hook and its mounting structure are subject to large tensile forces, so they must have sufficient strength to meet the requirements of use. The existing trailer hook mounting structure is generally fixed to the vehicle frame by welding. This fixing method cannot be disassembled or requires destructive cutting. In addition, the existing trailer hook mounting structure is welded to the vehicle frame. Regardless of whether the trailer hook is installed or not, this part of the trailer hook mounting structure is required. On the one hand, it increases the cost of the product, and on the other hand, it also takes up space in this area. Utility Model Content

[0013] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0014] Embodiment: A detachable trailer hook mounting structure.

[0015] Reference Figures 1 to 2 As shown, a detachable trailer hook mounting structure comprises: a frame assembly 1, a detachable trailer docking mechanism 2 is mounted on the bottom cross beam of the frame assembly 1, the detachable trailer docking mechanism 2 comprises a cross plate 21, a plurality of second screw holes 27 are provided on the cross plate 21, the second screw holes 27 are aligned with the screw holes provided on the top surface of the bottom cross beam of the frame assembly 1 and then locked by bolts 3, which greatly facilitates the installation and disassembly of the cross plate 21 and the bottom cross beam of the frame assembly 1, a longitudinal docking plate 23 extending forward is welded to the center of the cross plate 21, a "U"-shaped docking groove is provided on the longitudinal docking plate 23 that fits with the trailer 4, and pin shaft sockets 25 are provided on the left and right side surfaces of the longitudinal docking plate 23. After the rear end of the frame 4 is inserted into the "U"-shaped docking groove set on the longitudinal docking plate 23, it is fixedly connected to the longitudinal docking plate 23 after the pin shaft 6 passes through the pin shaft insertion hole 25 in the horizontal direction. A bottom limiting plate 22 is welded to the bottom of the transverse plate 21, and a plurality of first screw holes 26 are set on the bottom limiting plate 22. The first screw holes 26 are aligned with the screw holes set on the front side of the bottom cross beam of the frame assembly 1 and are locked by bolts 3, which greatly facilitates the installation and disassembly of the bottom limiting plate 22 and the bottom cross beam of the frame assembly 1. A reinforcing plate 24 is welded between the bottom limiting plate 22 and the longitudinal docking plate 23 to enhance the connection strength between the bottom limiting plate 22 and the longitudinal docking plate 23. The trailer hook 5 is installed at the front end of the trailer 4.

[0016] This detachable trailer hook mounting structure is rationally designed and easy to install and disassemble. During installation, simply align the transverse plate 21 and bottom stop plate 22 of the detachable trailer docking mechanism 2 with the bottom crossbeam of the frame assembly 1 and secure them with bolts 3. Then, insert the rear end of the trailer frame 4 into the U-shaped docking groove provided on the longitudinal docking plate 23. Then, insert the pin 6 transversely through the pin insertion hole 25 and securely connect it to the longitudinal docking plate 23. Installation is simple. To disassemble, simply loosen the bolts 3 and remove the detachable trailer docking mechanism 2 from the frame assembly 1. Compared to existing welded structures, this detachable trailer docking mechanism can be removed or assembled to the frame assembly 1 as desired, offering greater flexibility.

[0017] In addition, the existing trailer hook mounting structure is generally fixed to the vehicle frame assembly 1 by welding.
