Abstract
Description
Technical Field
[0001] This utility model relates to the field of rescue technology in the automotive repair industry, and in particular to a car traction device. Background Technology
[0002] In emergency situations, such as traffic accidents or vehicle breakdowns, car tow hitches can quickly provide rescuers with strong pulling force to help stranded vehicles get out of trouble.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] Example 1
[0030] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a car traction device. The car traction device includes a fixing component 100, including a front hook 101, a rear hook 102 and a replacement plate 103. The front hook 101 is fixed to one side of the replacement plate 103, and the rear hook 102 is located on the extension line of the other side of the replacement plate 103.
[0031] The front hook 101 is used to secure the towed vehicle. The replacement plate 103 is used to replace the front hook 101 when the towed vehicle hook model is incompatible. The rear hook 102 is used to secure the towed vehicle.
[0032] The dragging component 200 is disposed between the front hook 101 and the rear hook 102, and includes a fixing member 201 disposed on one side of the replacement plate 103. It includes a fixing seat 201a that is attached to the surface of the replacement plate 103. There are two rotating rings 201b fixed on one side of the fixing seat 201a, and they are arranged symmetrically to each other.
[0033] The drag assembly 200 is associated with and fixed to the front hook 101 by setting a fixed base 201a. A swivel ring 201b is fixed on one side of the fixed base 201a to facilitate rotational connection with other mechanisms.
[0034] Specifically, the dragging component 200 also includes a tension member 202, which is disposed on one side of the fixed base 201a. The tension member 202 includes a first rotating shaft 202a rotatably connected to the inner wall of the rotating ring 201b. The two ends of the first rotating shaft 202a are fixed with outer rods 202b. A first sliding groove 202b-1 is opened on the surface of the outer rod 202b. A compression spring 202c is disposed inside the outer rod 202b. One end of the compression spring 202c is fixedly connected to one side of the inner wall of the outer rod 202b.
[0035] Under the connection of the first rotating shaft 202a, the rotating ring 201b and the outer rod 202b can rotate relative to each other. One end of the compression spring 202c is connected to the outer rod 202b. When it is impacted, it applies a reverse force to the impact direction in order to reduce the impact force and prevent damage to the towed vehicle. The first groove 202b-1 is used to limit the length of the compression spring 202c when it is stretched and contracted.
[0036] Specifically, the tension member 202 also includes an inner rod 202d fixed to the other end of the compression spring 202c. The inner rod 202d slides inside the outer rod 202b. The other end of the inner rod 202d is fixed to a second rotating shaft 202e. A second sliding groove 202d-1 is opened on the surface of the inner rod 202d.
[0037] The compression spring 202c is connected to the inner rod 202d, and the inner rod 202d slides inside the outer rod 202b, so that the impact and pull are mitigated by the compression spring 202c during impact or dragging, reducing the occurrence of accidents. The second groove 202d-1 opened on the surface of the inner rod 202d is also used to limit the length of the compression spring 202c when it is stretched and contracted.
[0038] Specifically, the tensioning member 202 also includes a slider 202f, which slides within the second groove 202d-1 and the first groove 202b-1.
[0039] The slider 202f is used to limit the relative sliding position of the inner rod 202d and the outer rod 202b, so that the sliding distance is not too long.
[0040] Specifically, the drag component 200 also includes a limiting member 203, which is disposed on one side of the second rotating shaft 202e. The limiting member 203 includes a movable block 203a, one end of which is rotatably connected to the surface of the second rotating shaft 202e, and the other end of which is fixedly connected to a third rotating shaft 203b. A buffer beam 203c is disposed on one side of the movable block 203a, and a limiting groove 203c-1 is opened on the surface of the buffer beam 203c. The third rotating shaft 203b slides within the limiting groove 203c-1.
[0041] The movable block 203a is rotatably connected to the surface of the second rotating shaft 202e. The third rotating shaft 203b is fixed on one side of the movable block 203a and slides in the limiting slot 203c-1. When subjected to impact or tension, the inner rod 202d drives the movable block 203a and the third rotating shaft 203b to slide relative to each other along the limiting slot 203c-1 of the buffer beam 203c, providing buffer space for the impact or tension.
[0042] Example 2
[0043] Reference Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0044] Specifically, the dragging component 200 also includes a buffer 204, which is disposed on one side of the outer rod 202b. The buffer 204 includes a buffer shaft 204a, one side of which is fixed to the surface of the outer rod 202b. A rotating buckle 204b is rotatably connected to the surface of the buffer shaft 204a, and a retaining spring 204c is fixed to the other side of the rotating buckle 204b.
[0045] When the spring 204c is in a stretched state, the tension of the spring 204c causes the two outer rods 202b to approach each other under normal conditions. When subjected to impact, the tension member 202 stretches to both sides, and the inner rod 202d is pressed into the outer rod 202b. At this time, the two outer rods 202b move away from each other under the action of the buffer beam 203c. The spring 204c is further stretched, so that the spring 204c provides a buffer in the opposite direction to reduce the impact of the towed vehicle on the towing vehicle.
[0046] Specifically, the dragging assembly 200 also includes a dragging member 205, which is fixedly connected to the surface of the buffer beam 203c. The dragging member 205 includes a dragging head 205a, which is fixedly connected to the buffer beam 203c. A connecting beam 205b is fixed on one side of the dragging head 205a, and a rotating groove 205b-1 is provided at the other end of the connecting beam 205b.
[0047] The drag head 205a is used to fix the buffer beam 203c and connect the connecting beam 205b so that the buffer beam 203c can drive the connecting beam 205b forward during the pulling process. The rotating groove 205b-1 is used to connect the rear hook 102.
[0048] Example 3
[0049] Reference Figure 1 and Figure 6 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0050] Specifically, the rear hook 102 is rotatably connected to the rotating groove 205b-1.
[0051] The rotating groove 205b-1 allows the rear hook 102 to rotate, making it easier for the rear hook 102 to engage with the towed vehicle.
[0052] Specifically, the surface of the fixing seat 201a is provided with a threaded groove 201a-1, and the surface of the replacement plate 103 is provided with a through hole 103-1.
[0053] The groove 201a-1 and the through hole 103-1 correspond to each other and are used to fix the fixing seat 201a and the replacement plate 103.
[0054] Specifically, a bolt 104 is provided in the through hole 103-1, and the bolt 104 is located in the threaded groove 201a-1 and the through hole 103-1.
[0055] The bolt 104 and the threaded groove 201a-1 are used to fix the replacement plate 103 to the surface of the fixing seat 201a, preventing the two vehicles from separating during the towing process.
[0056] In use, first secure the rear hook 102 to the towed vehicle, then secure the front hook 101 to the towed vehicle. If the front hook 101 does not match the towed vehicle's hook model, remove bolt 104 to replace the front hook 101. Then, the towed vehicle will start and pull the towed vehicle. At this time, the tension member 202 will be stretched, and under the action of the compression spring 202c, the towed vehicle will be gradually pulled. During the traction process, in case of an emergency and the towed vehicle collides with the towed vehicle, the tension member 202 will be stretched to both sides under the action of the movable block 203a. The third rotating shaft 203b will rub against the limiting groove 203c-1, and the compression spring 202c will provide resistance for the inner rod 202d to enter the outer rod 202b. At the same time, the deflector spring 204c will also be stretched, tightening the outer rod 202b inward to prevent the towed vehicle from colliding with the towed vehicle and avoid secondary accidents.
[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
