Abstract
Description
Technical Field
[0001] The utility model relates to the field of trailer accessories, in particular to a track hooking structure for a trailer frame. Background Art
[0002] A trailer rack is a vehicle tool that is usually installed at the rear of the vehicle chassis. When there is insufficient storage space inside the vehicle body, or the items to be loaded are too large, or there are luggage items that are not suitable for placement in the vehicle, the trailer rack can provide a second storage space to assist the vehicle body in storing the luggage items, thereby expanding the vehicle's storage capacity.
[0003] When items are stored on a trailer frame, they need to be tied to the frame with straps to secure them in place. In the prior art, the traditional strapping method involves wrapping the straps around the items and hooking the ends of the straps onto the edges of the trailer frame, support poles, or other areas that can be hooked, pressing the items into place on the trailer frame. However, the areas on the trailer frame where the strap hooks are hooked are not specifically designed for hooks, and therefore present several problems: 1. The hooks have poor stability, meaning they are prone to slipping on the hooking areas; 2. The areas on the trailer where the hooks are hooked are limited, and when bundling different items, it is often difficult to find a suitable hooking area, making it difficult to secure the items. Therefore, the strapping method of the prior art requires further improvement. Utility Model Content

[0018] Figure 2 A schematic diagram of the track provided for this embodiment;
[0019] Figure 3 This is a schematic diagram of the hook assembly provided in this embodiment. DETAILED DESCRIPTION
[0020] Combine Figures 1 to 3 The rail hook structure for a trailer frame of the utility model is further described.
[0021] A track hooking structure for a trailer frame is characterized by comprising a track 1 and a hooking assembly 2.
[0022] The rail 1 has multiple mounting openings 111 distributed along its length. The hook assembly 2 comprises multiple groups, each of which is selectively installed in each mounting opening 111. Each hook assembly 2 includes a mounting base 25, a positioning group, and a hook component 26. The mounting base 25 has a slot 21 on each end, each capable of engaging with a position 112 at the edge of the mounting opening 111. The positioning group includes a positioning plate 24, a pin 23, and a torsion spring. The pin 23 is located near the bottom of the mounting base 25. One end of the positioning plate 24 is rotatably connected to the pin 23, while the other end is rotatable. The torsion spring is mounted on the pin 23. Its ends are respectively positioned in through-holes in the mounting base 25 and the positioning plate 24. This drives the end of the positioning plate 24 facing away from the pin 23 to rotate downward, engaging with the slot 21 on one end of the mounting base 25 to form an elastic slot 22. The hook component 26 is located at the top of the mounting base 25, for the hook on the strap to latch onto.
[0023] In the track 1 structure, the track 1 has an upwardly raised mounting portion 11 that extends along the length of the track 1. The mounting openings 111 are all formed on the mounting portion 11 and arranged along the extension direction of the mounting portion 11. The raised structure of the mounting portion 11 isolates the mounting portion 11 from the surface of the trailer frame when the track 1 is installed on the trailer frame, providing space for the bottom portion of the mounting seat 25 to be inserted into the mounting opening 111.
[0024] Connecting holes 12 are provided on both the left and right sides of the track 1 , and the track 1 can be fixed to the trailer frame through the connecting holes 12 and corresponding bolts.
[0025] The mounting opening 111 has downwardly angled, bent positioning tabs 113 on its corresponding front and rear inner walls. These positioning tabs 113 serve as abutments for the front and rear sidewalls of the mounting seat 25. When the mounting seat 25 is inserted into the mounting opening 111, that is, when the retaining slots 21 on the mounting seat 25 engage with the left and right edge positions 112 of the mounting opening 111, the lower sides of the positioning tabs 113 can abut against the sidewalls of the mounting seat 25, thereby enhancing the stability of the mounting seat 25 in the front-to-back direction. Furthermore, the angled positioning tabs 113 also give the mounting opening 111 a trumpet-shaped structure, facilitating the insertion of the mounting seat 25.
[0026] In this embodiment, the included angle between the positioning piece 113 and the mounting portion 11 is 45°.
[0027] The mounting base 25 is a U-shaped structure formed by bending a plate body, including a bottom plate and side plates located on both sides of the bottom plate. The two ends of the pin 23 are fixed to the two side plates, and the positioning plate 24 is located between the two side plates.
[0028] An extended section 251 is provided on one end of the elastic slot 22 at the bottom of the mounting seat 25 to deepen the depth of the elastic slot 22, so that the slots 21 at both ends of the mounting seat 25 can be effectively engaged with the edge positions on the left and right sides of the mounting opening 111, and then the mounting seat 25 is positioned on the mounting opening 111 through the elastic slot 22 formed by the positioning plate 24 and one of the slots 21, that is, the end of the positioning plate 24 facing away from the pin shaft 23 is pressed against the upper surface of the mounting part 11 to form a fixed structure, thereby preventing the hook component 2 from falling out of the mounting opening 111.
[0029] The hooking components 26 are a pair of hooks welded to the top of the mounting seat 25 .
[0030] During use, the two sets of track hooking structures are bolted to the trailer frame. After the straps are wrapped around the items, the hooks at both ends can be hooked onto the hooks of the two sets of track hooking structures, respectively, to press the items onto the trailer frame. In this structure, the provision of hooking components 26, such as hooks, for the hooks to hook onto can significantly improve the stability of the hooks during hooking. Furthermore, the hook assembly 2 can be installed in different mounting openings 111 of the track 1 according to the needs of the items, thereby adapting to the hooking requirements of the straps at different locations, significantly improving the convenience of bundling items.
