Description

Technical Field

[0001] This utility model relates to the field of trailer shackles, and in particular to a multi-functional, split-type, easy-to-disassemble trailer shackle. Background Technology

[0002] A trailer shackle is an important device used to connect a trailer and a tractor. It is generally made of high-strength metal, with alloy steel being a common material. Its shape is usually a ring or U-shaped structure, which can provide good load-bearing capacity. For example, the ends of a U-shaped trailer shackle are relatively thick, and the middle part forms an arc-shaped opening for connecting the trailer's towing device and the tractor's hook.

[0003] Traditional trailer shackles typically require disassembling the entire shackle assembly for quick and easy removal and installation. However, during rescue operations, the position of the tow rope often needs to be changed frequently, such as towing from the front of the vehicle or switching to the rear. This necessitates frequent removal of the trailer shackle and replacement of the tow rope, making it inconvenient to use.

[0004] Therefore, it is necessary to provide a multi-functional, modular, easy-to-disassemble trailer shackle to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a multi-functional, modular, and easily detachable trailer shackle, which solves the problem of needing to disassemble the entire shackle device and frequently disassemble and install the trailer shackle when changing the towing direction during rescue operations.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-functional, split-type, easy-to-disassemble trailer shackle, comprising:

[0007] Mounting rod;

[0008] Two connecting rods are respectively disposed at both ends of the mounting rod. One end of each connecting rod is fixedly connected to a bolt. Nuts are fitted on the surface of each bolt, and hexagonal screws are provided inside the nuts.

[0009] Two shackles are respectively disposed on the surfaces of the two connecting rods. Each of the two shackles has a positioning hole inside and a magnet is fixedly installed inside each of the two shackles.

[0026] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0027] First Embodiment

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of a multi-functional, split-type, easily detachable trailer shackle provided by this utility model; Figure 2 for Figure 1 The diagram shown illustrates the working state of the shackle. Figure 3 for Figure 1 The diagram shows the overall structure of the shackle.

[0029] Figure 4 for Figure 1 The diagram shows the structure of the mounting rod. Figure 5 for Figure 1 The diagram shows the structure of the bolt. A multi-functional, modular, easy-to-install trailer shackle includes:

[0030] Mounting rod 1;

[0031] Two connecting rods 2 are respectively set at both ends of the mounting rod 1. One end of each of the two connecting rods 2 is fixedly connected to a bolt 3. Nuts 4 are fitted on the surface of each of the two bolts 3. Hexagonal screws 10 are provided inside the nuts 4.

[0032] Two shackles 5 are respectively disposed on the surface of the two connecting rods 2. Each of the two shackles 5 has a positioning hole 6 inside and a magnetic sheet 9 is fixedly installed inside each of the two shackles 5.

[0033] The two shackles 5 can be quickly attached to the tow rope through a simple opening and closing operation. Compared with the traditional shackle operation, it is more convenient and efficient, has a wide range of applications, can meet the needs of most towing rescue work, and has strong adaptability. The split design not only maintains the high load-bearing capacity of the shackle, but also improves the working tensile strength through the two-piece split structure.

[0034] Because the product is made of carbon steel, it is relatively heavy and prone to separation of the two parts due to gravity. The magnetic sheet 9 is used to ensure that the two parts remain tightly connected when not in operation, preventing them from falling off. The magnet effectively increases the stability and safety of the shackle without affecting its function.

[0035] The center of the magnetic plate 9 is fixed with a stainless steel screw. The stainless steel screw can effectively reduce failures caused by rust or falling off, improve the service life of the shackle, and ensure long-term reliability.

[0036] By precisely adjusting the size of the positioning hole 6 of the shackle 5, the shackle 5 can be firmly hung on the connecting rod 2 and play the role of fixing the shackle. This slot design can prevent the shackle 5 from accidentally loosening during operation and increase the safety during use.

[0037] To prevent nut 4 from loosening after installation and to avoid nut 4 from becoming loose or lost, nut 4 is secured with concealed hexagonal screws 10. This not only effectively prevents the nut from loosening and ensures the safe use of the shackle, but also has a certain anti-theft function, thus improving the security of the equipment.

[0038] The threads on the nut 4 and the bolt 3 are aligned by having threaded holes in the interior of both the nut 4 and the bolt 3 that are compatible with the hexagonal screw 10. After the nut 4 is installed on the surface of the bolt 3, the threads on the nut 4 and the bolt 3 are aligned, and then the hexagonal screw 10 is installed.

[0039] Alternatively, by providing a threaded hole inside the nut 4 that is compatible with the hexagonal screw 10, when the hexagonal screw 10 is rotated to one side, one end of the hexagonal screw 10 contacts the surface of the bolt 3, thus limiting the nut 4. After one end of the hexagonal screw 10 separates from the bolt 3, the nut 4 can rotate to one side.

[0040] One end of each of the two connecting rods 2 is fixedly connected to both ends of the mounting rod 1, and the other end is fixedly connected to one end of each of the two bolts 3.

[0041] Both shackles 5 have positioning grooves 7 inside, and both shackles 5 have positioning blocks 8 fixedly connected to one side.

[0042] The positioning groove 7, together with the positioning block 8, is used to position the two shackles 5 when they are combined, while preventing the shackles from sliding or falling off during use. This ensures that the separate shackles are always in the correct position and enhances the stability of the overall structure.

[0043] The working principle of the multi-functional, split-type, easy-to-disassemble trailer shackle provided by this utility model is as follows:

[0044] When using the shackles 5, they are installed by fitting the two positioning holes 6 of the two shackles 5 onto the surfaces of the two connecting rods 2, and then installing them onto the surfaces of the two bolts 3 with the two nuts 4.

[0045] When the trailer rope with the rope loop is placed on the surface of the two shackles 5, the two towing hooks 5 are separated, and the rope loop is moved through the gap between the two shackles 5 and placed on the surface of one shackle 5. After it is placed on the surface of the other shackle 5, the two shackles 5 are joined together and then limited by the magnetic plate 9.

[0046] Compared with related technologies, the multi-functional, split-type, easy-to-disassemble trailer shackle provided by this utility model has the following advantages:

[0047] This utility model provides a multi-functional, modular, easily detachable trailer shackle. Two bolts and two nuts 4 are used to secure two shackles 5 to the surfaces of two connecting rods 2, thus limiting their position. This modular design allows for quick connection and disassembly without disassembling the entire device. Furthermore, it significantly improves operational and rescue efficiency in environments where trailer equipment is frequently changed or adjusted. After separating the two shackles 5, the trailer rope with the pre-tied loops can be directly placed inside the two shackles 5, facilitating frequent changes to the trailer rope's position.

[0048] Second embodiment

[0049] Please refer to Figure 6 and Figure 7 Based on the first embodiment of this application which provides a multi-functional, modular, easily detachable trailer shackle, the second embodiment of this application proposes another multi-functional, modular, easily detachable trailer shackle. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0050] Specifically, the second embodiment of this application provides a multi-functional, split-type easy-to-disassemble trailer shackle that differs in that the surface of the mounting rod 1 is provided with a limiting clamp 11, the inside of the limiting clamp 11 is rotatably connected to a rotating rod 12, and the surface of the rotating rod 12 is fixedly connected to a rotating clamp 13.

[0051] The rotating clamp 13 is provided with a fixing member 14 inside, and the surfaces of the limiting clamp 11 and the rotating clamp 13 are both fixedly connected with protective sleeves 19.

[0052] The fixing component 14 is a bolt. The limiting clamp 11 and the rotating clamp 13 are both provided with threaded holes that are compatible with the bolt. After the bolt is installed into the threaded hole, the rotating clamp 13 and the limiting clamp 11 are limited.

[0053] The protective sleeve 19 is made of rubber and is used to increase the friction between the rotating clamp 13 and the limiting clamp 11, thereby increasing the fixing effect.

[0054] A rotating rod 15 is fixedly connected to one side of the limiting clamp 11, and a rotating sleeve 16 is threadedly connected to the surface of the rotating rod 15.

[0055] The rotating rod 15 is a threaded rod, and the rotating sleeve 16 is a threaded sleeve adapted to the rotating rod 15. The thread of the rotating rod 15 is adapted to the thread of the threaded hole of the trailer hook on the vehicle, so that the trailer shackle can be used even when there is no trailer hook.

[0056] One end of the rotating sleeve 16 is fixedly connected to a mounting plate 17, and the mounting plate 17 has multiple mounting holes 18 inside.

[0057] Multiple mounting holes 18 are used to fit bolts to install the mounting plate 17 in a suitable position on the vehicle frame, thereby facilitating the installation of the trailer shackle in the appropriate position for towing the vehicle.

[0058] The working principle of the multi-functional, split-type, easy-to-disassemble trailer shackle provided by this utility model is as follows:

[0059] In use, after placing the mounting plate 17 in the appropriate position, the bolts are installed into the mounting holes 18 and then onto the frame to limit the mounting plate 17.

[0060] When it is necessary to install it into the threaded hole of the trailer hook on the frame, the rotating rod 15 is rotated to one side, thereby moving and separating it to one side inside the rotating sleeve 16. After the rotating rod 15 is aligned with the threaded hole on the frame, it is rotated to one side, so that the rotating rod 15 moves to the appropriate position inside the threaded hole.

[0061] Compared with related technologies, the multi-functional, split-type, easy-to-disassemble trailer shackle provided by this utility model has the following advantages:

[0062] This utility model provides a multi-functional, split-type, easy-to-disassemble trailer shackle.
