Description

Technical Field

[0001] This utility model belongs to the technical field of tow hooks for special vehicles, and particularly relates to a tow hook for special vehicles that is easy to store. Background Technology

[0002] A patent titled "A Tow Hook Device for Special Vehicles" is disclosed in the existing Chinese patent database. The application number is CN202420642052.8, and the application date is March 31, 2024. This tow hook device, belonging to the field of automobile tow hook technology, includes a mounting plate. A limiting block is fixedly connected to the surface of the mounting plate. The limiting block has an adjustment chamber and a movable groove inside. The movable groove is located on both sides of the adjustment chamber. A bearing is fixedly connected to the surface of the adjustment chamber so that a first rotating shaft passes through it. A first bevel gear is fixedly connected to the bottom end of the first rotating shaft. The beneficial effect of this tow hook device for special vehicles is that, by setting a threaded column and a threaded tube, when the operator uses the device to install the towing ring, the operator only needs to rotate the first rotating shaft by turning a knob. With the cooperation of the first and second bevel gears, the threaded column can drive the threaded tube to move into the positioning groove, thus facilitating the installation and removal of the towing ring of the tow hook.

[0003] This article aims to propose a special vehicle tow hook that is easy to store, can be folded up when not in use, and does not occupy the space on the outside of the vehicle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to design a vehicle tow hook that can be folded up when not in use and does not occupy the space outside the vehicle. In order to improve its shortcomings, this utility model provides a special vehicle tow hook that is easy to store.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A special vehicle tow hook that is easy to store includes a connecting plate for fixing to the special vehicle. Both connecting plates are provided with hook grooves, each hook groove having a wide hole and a narrow hole. A pin is inserted into the two hook grooves. The cross-section of the pin is rectangular. The relationship between the long side L1, the short side L2, the width L3 of the narrow hole, and the width L4 of the wide hole of the pin is: L2≤L3<L1<L4. A tow hook body is integrally provided on the pin located between the two connecting plates.

[0007] Compared with the prior art, the beneficial effects of this utility model are: due to the matching arrangement of the hook groove and the pin shaft, the tow hook can be placed vertically and fit the vehicle when not in use, without taking up space. When in use, the pin shaft is lifted upward and rotated to a horizontal state, and the free end of the tow hook body will not hit the ground, thus improving the safety of use. This device is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, the connecting plate is L-shaped, with the horizontal section of the connecting plate fixed to the special vehicle, and the hook groove is formed on the vertical section of the connecting plate.

[0009] As a preferred embodiment, it includes a base plate that is fixedly connected to a special vehicle, and the horizontal section of the connecting plate is welded to the surface of the base plate.

[0010] As a preferred embodiment, fixing holes are provided at all four corners of the substrate.

[0011] As a preferred embodiment, the tow hook body includes an integrally formed support portion and a hook body portion. The support portion is formed by welding several horizontal and vertical bars into a frame shape. The hook body portion includes a hook plate welded to the free end of the support portion, and the hook plate has a hook hole. Attached Figure Description

[0013] Figure 2 This is a structural schematic diagram of the present invention in its non-use state.

[0014] Figure 3 This is a structural diagram of the present invention in use.

[0015] In the figure: 1 connecting plate, 101 horizontal plate section, 102 vertical plate section, 2 hook groove, 201 wide hole section, 202 narrow hole section, 3 pin shaft, 4 tow hook body, 401 bracket section, 402 hook body section, 403 hook plate, 404 hook hole, 5 base plate, 6 fixing hole. Detailed Implementation

[0016] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3As shown, a special vehicle tow hook that is easy to store includes a connecting plate 1 fixed to the special vehicle. Both connecting plates 1 have hook grooves 2, each with a wide hole 201 and a narrow hole 202. A pin 3 is inserted into each hook groove 2. The pin 3 has a rectangular cross-section. The relationship between the long side L1, short side L2, width L3 of the narrow hole 202, and width L4 of the wide hole 201 of the pin 3 is: L2≤L3<L1<L4. A tow hook body 4 is integrally formed on the pin 3 located between the two connecting plates 1. The connecting plate 1 is L-shaped, with its horizontal section 101 fixed to the special vehicle. The hook grooves 2 are formed on the vertical section 102 of the connecting plate 1. It also includes a base plate 5 fixed to the special vehicle, with the horizontal section 101 of the connecting plate 1 welded to the surface of the base plate 5. Fixing holes 6 are formed at each of the four corners of the base plate 5. The tow hook body 4 includes an integrally formed support part 401 and hook part 402. The support part 401 is formed by welding several horizontal and vertical bars to form a frame. The hook part 402 includes a hook plate 403 welded to the free end of the support part 401. The hook plate 403 is provided with a hook hole 404.

[0018] In the initial state, the tow hook 4 is vertically aligned with the vehicle. At this time, the pin 3 is located in the narrow hole 202 of the hook groove 2. The entire tow hook 4 and the pin 3 cannot rotate. The narrow hole 202 limits the rotation of the pin 3. When needed, the tow hook 4 and the pin 3 are lifted vertically upward together. After lifting, they are rotated 90 degrees so that the pin 3 is located in the wide hole 201. At this time, the entire tow hook 4 and the pin 3 cannot move downward. The positional relationship between the wide hole 201 and the pin 3 limits the tow hook 4, and the free end of the tow hook 4 will not hit the ground, providing a certain degree of safety protection during use.

[0019] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
