Description
Technical Field
[0001] This utility model relates to the technical field of tow hooks, and in particular to a tow hook installation reinforcement structure. Background Technology
[0002] A tow hook is a device used to connect and tow other vehicles or equipment. It is mainly used to tow trailers, storage boxes and other towed equipment. It can also be used to help other vehicles get out of trouble. However, tow hooks often require a corresponding installation structure to be used.
[0003] When installing tow hooks, traditional tow hooks are often fixed to the crash beam by a single bolt connection or simple sleeve welding. This installation method will damage the overall structural strength of the mounting base, and the force transmission path at the connection point is singular. When subjected to towing force, especially the longitudinal traction force of heavy towing equipment, there is a risk of weld breakage, sleeve breakage or crash beam detachment, which seriously affects the safety of use. At the same time, disassembly after installation still requires treatment of the welded parts, which is not convenient to operate. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0005] Therefore, one objective of this utility model is to propose a reinforced structure for tow hook installation. By optimizing the installation method at the connection between the base and the tow hook, it eliminates the need for excessive reliance on bolts or welding during installation and effectively avoids the loosening or breakage that is prone to occur with traditional bolt and welding fixation during use.
[0006] To achieve the above objectives, the first aspect of this utility model proposes a tow hook mounting reinforcement structure, comprising: a base, a tow hook, and a mounting mechanism. The base has a mounting hole, the tow hook is disposed within the mounting hole, and the mounting mechanism is disposed within the mounting hole. The mounting mechanism includes a mounting tube, a mounting seat, a fixing plate, a cover plate, a limiting component, and a control component. The inner wall of the mounting hole has a mounting groove, the mounting tube is disposed within the mounting groove, the mounting seat is disposed at one end of the mounting tube, the fixing plate is rotatably connected to the mounting seat, the cover plate is disposed within the mounting groove, the limiting component is disposed on the fixing plate, the control component is disposed within the mounting tube, and a limiting hole is formed on the outer wall of the tow hook.
[0007] In addition, the tow hook mounting reinforcement structure proposed above according to this utility model may also have the following additional technical features: Specifically, the limiting assembly includes a first connecting seat, a connecting plate, a telescopic rod, and a first spring. The first connecting seats are respectively disposed on the outer wall of the fixed plate and the inner wall of the mounting groove. The connecting plates are rotatably connected to the corresponding first connecting seats. The telescopic rod is disposed on the connecting plate, and both ends of the telescopic rod are respectively connected to the corresponding connecting plates. The first spring is sleeved on the outer wall of the telescopic rod, and both ends of the first spring are respectively connected to the corresponding connecting plates.
[0008] Specifically, a limiting shell is provided inside the mounting hole, and a second spring is provided inside the mounting hole, with the other end of the second spring connected to the limiting shell.
[0009] Specifically, a sliding groove is provided in the mounting hole, and a slider is provided on the outer wall of the limiting shell.
[0010] Specifically, the control assembly includes a control tube, a control cone, a connecting rod, and a control plate. The control tube is located inside the mounting tube, the control cone is fixed to one end of the control tube, and the connecting rod is located at the other end of the control tube. The other end of the connecting rod passes through the cover plate and is connected to the control plate.
[0011] Specifically, a support assembly is provided on the base. The support assembly includes a sleeve, a second connecting seat, a mounting plate, a damper, and a third spring. The sleeve is fitted onto the outer wall of the tow hook. The second connecting seats are respectively located on the outer wall of the sleeve and the side wall of the base. The mounting plates are rotatably connected to the corresponding second connecting seats. The damper is located on the mounting plate, and both ends of the damper are connected to the mounting plate. The third spring is fitted onto the outside of the damper, and both ends of the third spring are connected to the mounting plate.
[0012] Compared with the prior art, the present invention has the following advantages: by optimizing the installation method of the connection between the base and the tow hook, it does not need to rely excessively on bolts or welding during the installation process. At the same time, during use, the multiple fixing plates set inside the base can disperse the tension on the tow hook, ensuring that it will not loosen or break during long-term use as is the case with traditional bolt fixing and welding fixing.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0017] The following description, with reference to the accompanying drawings, describes a tow hook mounting reinforcement structure according to an embodiment of the present invention.
[0018] like Figures 1-5 As shown, a tow hook installation reinforcement structure according to an embodiment of the present invention includes: a base 1, a tow hook 3, and an installation mechanism 4. The base 1 has an installation hole 2, the tow hook 3 is disposed in the installation hole 2, and the installation mechanism 4 is disposed in the installation hole 2. The installation mechanism 4 includes an installation tube 42, an installation seat 43, a fixing plate 44, a cover plate 45, a limiting component 46, and a control component 47. The inner wall of the installation hole 2 has an installation groove 41, the installation tube 42 is disposed in the installation groove 41, the installation seat 43 is disposed at one end of the installation tube 42, the fixing plate 44 is rotatably connected to the installation seat 43, the cover plate 45 is disposed in the installation groove 41, the limiting component 46 is disposed on the fixing plate 44, the control component 47 is disposed in the installation tube 42, and the outer wall of the tow hook 3 has a limiting hole 48.
[0019] Specifically, when installing the tow hook 3, the relevant personnel will first insert the tow hook 3 into the mounting hole 2 on the base 1. At this time, the outer wall of the tow hook 3 will push the fixing plate 44 outward. At this time, the fixing plate 44 will squeeze the first spring 464. The first spring 464 will store and compress. Then, when the limiting hole 48 on the outer wall of the tow hook 3 contacts the fixing plate 44, the first spring 464 will push the fixing plate 44 out, so that it will be locked into the limiting hole 48 for fixation.
[0020] In one embodiment of this application, such as Figure 2 , Figure 3 and Figure 5 As shown, the limiting component 46 includes a first connecting seat 461, a connecting plate 462, a telescopic rod 463, and a first spring 464. The first connecting seat 461 is respectively disposed on the outer wall of the fixing plate 44 and the inner wall of the mounting groove 41. The connecting plate 462 is rotatably connected to the corresponding first connecting seat 461. The telescopic rod 463 is disposed on the connecting plate 462, and both ends of the telescopic rod 463 are respectively connected to the corresponding connecting plate 462. The first spring 464 is sleeved on the outer wall of the telescopic rod 463, and both ends of the first spring 464 are respectively connected to the corresponding connecting plate 462. A limiting shell 465 is disposed in the mounting hole 2. A second spring 466 is disposed in the mounting hole 2, and the other end of the second spring 466 is connected to the limiting shell 465. A sliding groove 467 is opened in the mounting hole 2, and a slider 468 is disposed on the outer wall of the limiting shell 465.
[0021] Control assembly 47 includes a control tube 471, a control cone 472, a connecting rod 473, and a control plate 474. The control tube 471 is disposed inside the mounting tube 42. The control cone 472 is fixed to one end of the control tube 471. The connecting rod 473 is disposed at the other end of the control tube 471. The other end of the connecting rod 473 passes through the cover plate 45 and is connected to the control plate 474. Specifically, as the tow hook 3 is inserted, the fixing plate 44 presses against the connecting plate 462, and the connecting plate 462 presses against the telescopic rod 463 and the first spring 464. At this time, the first spring 464 is compressed and stored. When the limiting hole 48 on the outer wall of the tow hook 3 contacts the fixing plate 44, the first spring 464 resets and pushes the fixing plate 44 out through the connecting plate 462, so that it is locked into the limiting hole 48 for reinforcement. At the same time, when the tow hook 3 is inserted, one end of the tow hook 3 contacts the limiting shell 465 in the mounting hole 2 and presses against the second spring 466 through the limiting shell 465. At this time, the second spring 466 is compressed and stored. After the fixing plate 44 is locked into the limiting hole 48, the tow hook 3 is pushed outward, so that the fixing plate 44 can contact the inner wall of the limiting hole 48, thereby enhancing its installation effect.
[0022] When the tow hook 3 needs to be disassembled, the relevant personnel push the control plate 474. The control plate 474 pushes the control tube 471 through the connecting rod 473. At this time, the control tube 471 slides towards the fixed plate 44, and pushes the fixed plate 44 outward through the control cone 472 on the control tube 471. At this time, as the fixed plate 44 unfolds outward, its engagement with the limiting hole 48 is released. As the fixed plate 44 unfolds, it will compress the first spring 464 outward. At this time, the first spring 464 is compressed and stored. At the same time, during the unfolding process, one side of the fixed plate 44 will push the tow hook 3 into the mounting hole 2. During the process of the fixed plate 44 pushing the tow hook 3 into the mounting hole 2, the tow hook 3 will further compress the second spring 466. At this time, the second spring 466 is compressed and stored. When the fixing plate 44 is fully extended and no longer limits the locking of the tow hook 3, the second spring 466 will use its own stored force to pop the tow hook 3 out of the mounting hole 2 a certain distance, making it convenient for the staff to remove the tow hook 3 from the base 1 and complete the disassembly of the tow hook 3.
[0023] In one embodiment of this application, such as Figure 4 As shown, a support assembly 5 is provided on the base 1. The support assembly 5 includes a sleeve 51, a second connecting seat 52, a mounting plate 53, a damper 54, and a third spring 55. The sleeve 51 is sleeved on the outer wall of the tow hook 3. The second connecting seat 52 is respectively disposed on the outer wall of the sleeve 51 and the side wall of the base 1. The mounting plate 53 is rotatably connected to the corresponding second connecting seat 52. The damper 54 is disposed on the mounting plate 53, and both ends of the damper 54 are respectively connected to the mounting plate 53. The third spring 55 is sleeved on the outside of the damper 54, and both ends of the third spring 55 are respectively connected to the mounting plate 53.
[0024] Specifically, when installing the tow hook 3, the tow hook 3 is first passed through the sleeve 51 and then inserted into the mounting hole 2. During the use of the tow hook 3, when the tow hook 3 is subjected to external force and shakes, the sleeve 51 will also shift to a certain extent. At this time, the second connecting seat 52 connected to the outer wall of the sleeve 51 will squeeze the damper 54 through the mounting plate 53. The damper 54 consumes part of the energy generated by the shaking through its own damping characteristics, playing a role in buffering and shock absorption. At the same time, the third spring 55 sleeved on the outside of the damper 54 will also deform, further absorbing and dispersing the impact force brought by the shaking, thereby effectively reducing the shaking amplitude of the tow hook 3, ensuring the stability of the tow hook 3 during use, and avoiding damage to the base 1 and other related components due to excessive shaking, thereby achieving a strengthening effect.
[0025] Working principle: When installing the tow hook 3, the relevant personnel first insert the tow hook 3 into the mounting hole 2 on the base 1. At this time, the outer wall of the tow hook 3 pushes the fixing plate 44 outward. The fixing plate 44 then compresses the first spring 464. The first spring 464 is then compressed and stored. Then, when the limiting hole 48 on the outer wall of the tow hook 3 contacts the fixing plate 44, the first spring 464 pushes the fixing plate 44 out, so that it is locked into the limiting hole 48 for fixation. As the tow hook 3 is inserted, the fixing plate 44 compresses the connecting plate 462, and the connecting plate 462 compresses the telescopic rod 463 and the first spring 464. At this time, the first spring 464 is compressed and stored. When the limiting hole 48 on the outer wall of the tow hook 3 contacts the fixing plate 44, the first spring 464 resets and pushes the fixing plate 44 out through the connecting plate 462, so that it is locked into the limiting hole 48 for reinforcement. At the same time, when the tow hook 3 is inserted, one end of the tow hook 3 will contact the limiting shell 465 in the mounting hole 2 and squeeze the second spring 466 through the limiting shell 465. At this time, the second spring 466 is compressed and stored. After the fixing plate 44 is locked into the limiting hole 48, the tow hook 3 is pushed outward, so that the fixing plate 44 can contact the inner wall of the limiting hole 48, thereby enhancing its installation effect.
[0026] When the tow hook 3 needs to be disassembled, the relevant personnel push the control plate 474. The control plate 474 pushes the control tube 471 through the connecting rod 473. At this time, the control tube 471 slides towards the fixed plate 44, and pushes the fixed plate 44 outward through the control cone 472 on the control tube 471. At this time, as the fixed plate 44 unfolds outward, its engagement with the limiting hole 48 is released. As the fixed plate 44 unfolds, it will compress the first spring 464 outward. At this time, the first spring 464 is compressed and stored. At the same time, during the unfolding process, one side of the fixed plate 44 will push the tow hook 3 into the mounting hole 2. During the process of the fixed plate 44 pushing the tow hook 3 into the mounting hole 2, the tow hook 3 will further compress the second spring 466. At this time, the second spring 466 is compressed and stored. When the fixing plate 44 is fully extended and no longer limits the locking of the tow hook 3, the second spring 466 will use its stored elasticity to eject the tow hook 3 a certain distance from the mounting hole 2, making it convenient for the operator to remove the tow hook 3 from the base 1 and complete the disassembly of the tow hook 3. When installing the tow hook 3, first pass the tow hook 3 through the sleeve 51 and then insert it into the mounting hole 2. During the use of the tow hook 3, when the tow hook 3 is subjected to external force and shakes, the sleeve 51 will also shift to a certain extent. At this time, the second connecting seat 52 connected to the outer wall of the sleeve 51 will squeeze the damper 54 through the mounting plate 53. The damper 54 consumes part of the energy generated by the shaking through its own damping characteristics, playing a role in buffering and shock absorption. At the same time, the third spring 55 sleeved on the outside of the damper 54 will also deform, further absorbing and dispersing the impact force brought by the shaking, thereby effectively reducing the shaking amplitude of the tow hook 3, ensuring the stability of the tow hook 3 during use, and avoiding damage to the base 1 and other related components due to excessive shaking, thus achieving a strengthening effect.
