Description

Technical Field

[0001] The utility model relates to the field of trailer parts, in particular to a slidable bolting ring structure. Background Art

[0002] Hitches, also known as rope hooks, rope loops, and lashing devices, are usually installed on the side and body of a trailer to connect lashing ropes and lashing chains.

[0003] Chinese utility model patent publication number CN205992706U discloses a cable hook for a semitrailer. The cable hook comprises a main body composed of an upper straight section joined to a lower arc section. A cross plate is attached to the top of the upper straight section, and two dovetail slots are defined on the upper surface of the cross plate. However, due to structural design and strapping requirements, some cable hooks are mounted on the trailer frame and protrude from the upper surface of the frame, interfering with cargo loading.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0005] To improve or resolve the technical problem in the prior art where a hitch ring protrudes from the upper surface of a vehicle frame, interfering with cargo loading, the present invention provides a slidable hitch ring structure. The hitch ring structure comprises: a rope ring comprising a main body and a guide slide mounted on the main body; a mounting frame having a housing for accommodating the rope ring; a guide slot extending vertically and cooperating with the guide slide, the guide slide configured to slide along the guide slot to switch between a hidden state and an extended state; the hidden state means the main body is hidden within the housing, and the extended state means the main body is extended from the housing.

[0006] In the utility model, a slidable bolting ring structure includes a rope ring and a mounting frame. The rope ring includes a main body and a guide slide rod. A accommodating cavity is formed in the mounting frame and a guide slide groove extending in the up-down direction is provided, so that the rope ring can be slidably mounted on the mounting frame. When the rope ring does not need to be connected to the strapping belt, the rope ring is in a hidden state, and the main body is hidden in the accommodating cavity to avoid interfering with the loading of goods; when the rope ring needs to be connected to the strapping belt, the rope ring switches to an extended state, the guide slide rod slides upward along the guide slide groove, and the main body extends out of the accommodating groove to facilitate connection with the strapping belt. Through the above-mentioned settings, the utility model provides a slidable bolting ring structure with a guide slide rod and a guide slide groove, which can be hidden in the mounting frame when the rope ring is not needed to avoid interfering with the loading of goods, and can be pulled out when the rope ring is needed. The structure is simple and easy to use.

[0007] Furthermore, the guide chute includes a vertically extending lower portion and an obliquely extending upper portion connected to the lower portion. With this arrangement, the obliquely arranged upper portion blocks the rope loop when it bounces due to a bump in the frame, preventing the rope loop from bouncing excessively, protecting the rope loop and the mounting frame, and extending the service life of the hitch ring structure.

[0008] Furthermore, the guide slide bar is formed with an anti-flipping surface that abuts against the mounting bracket; the width of the upper half is greater than that of the lower half. This arrangement prevents the guide slide bar from rotating within the lower half, further protecting the rope loop and mounting bracket and extending the service life of the hitch ring structure.

[0009] Furthermore, the mounting frame includes a first side panel, a second side panel arranged opposite to the first side panel, and a back panel connecting the first side panel and the second side panel, and the guide slots are provided on the first side panel and the second side panel.

[0010] Furthermore, the mounting frame includes a panel positioned opposite the back panel and abutting the rope loop. This arrangement reduces the stress on the guide rod and extends the life of the tie-loop structure. The panel also prevents the guide rod from excessively rotating within the upper portion, ensuring that the guide rod mates with the lower portion, facilitating the transition of the rope loop from an extended to a concealed position.

[0011] Furthermore, the mounting frame is provided with an opening connected to the accommodating cavity.

[0012] Furthermore, the mounting frame also includes a top plate connected to the panel, the first side plate, the second side plate, and the back plate, and the opening is opened on the top plate and the panel.

[0013] Furthermore, a tying post is provided between the first side plate and the second side plate. Through the above arrangement, the tying post is used to connect the tying belt, and the tying post and the rope ring do not interfere with each other and can be selected as needed, thereby enhancing the applicability of the tying ring structure.

[0014] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) A guide slide bar and a guide slot are provided, which can be hidden in the mounting frame when the rope ring is not needed to avoid interfering with cargo loading, and can be pulled out when the rope ring is needed, with a simple structure and easy use;

[0016] (2) The inclined upper part blocks the rope ring when it bounces due to the bumping of the frame, preventing the rope ring from being shaken too much, protecting the rope ring and the mounting frame, and extending the service life of the hitch ring structure.

[0026] To improve or resolve the technical problem of hitch rings protruding from the upper surface of the vehicle frame, interfering with cargo loading, the present invention provides a slidable hitch ring structure. The hitch ring structure comprises: a rope ring 1, comprising a main body 11 and a guide slide 12 mounted on the main body 11; a mounting frame 2, within which is formed a receiving cavity for accommodating the rope ring 1; a guide slot 27 extending vertically and cooperating with the guide slide 12, formed on the mounting frame 2. The guide slide 12 is configured to slide along the guide slot 27 to switch between a hidden state and an extended state. The hidden state means that the main body 11 is hidden within the receiving cavity, and the extended state means that the main body 11 is extended from the receiving cavity.

[0027] Figure 1 This is a schematic diagram of a first embodiment of a slidable tethered ring structure of the present invention. Figure 2 This is another schematic diagram of the first embodiment of a slidable tethered ring structure of the present invention. Figure 1 and Figure 2 As shown, the utility model is a slidable tying ring structure comprising a rope ring 1 and a mounting frame 2.

[0028] Continue to see Figure 1 and Figure 2 In one or more embodiments, the rope ring 1 includes a main body 11 and a guide slide bar 12 installed on the main body 11. The main body 11 is roughly arched. A through hole is provided on the main body 11 for connecting the strapping belt. Furthermore, the guide slide bar 12 is provided on both sides of the main body 11 for connecting to the mounting frame 2. An anti-flip plane 13 is formed on the guide slide bar 12. Specifically, the anti-flip plane 13 is formed by cutting a portion of the guide slide bar 12 having a circular cross-section along the chord direction to prevent the main body 11 from flipping. Alternatively, the guide slide bar 12 can be set to other suitable shapes, such as a quadrangular prism, a hexagonal prism, etc., and the anti-flip plane 13 is a surface of a quadrangular prism or a hexagonal prism.

[0029] Continue to see Figure 1 and Figure 2In one or more embodiments, the mounting frame 2 includes a first side panel 21, a second side panel 22 arranged opposite to the first side panel 21, a back panel 23 connecting the first side panel 21 and the second side panel 22, a panel 24 arranged opposite to the back panel 23, a top panel 25, and a bottom panel arranged opposite to the top panel 25. The top panel 25, the bottom panel, the first side panel 21, the second side panel 22, the back panel 23, and the panel 24 are connected to each other to form a receiving cavity for accommodating the rope ring 1. Openings are provided on the top panel 25 and the panel 24 for the rope ring 1 to extend out and for the staff to take the rope ring 1. At the openings, the first side panel 21 and the second side panel 22 protrude from the top panel 25 and the panel 24 to form welds 26. The welds 26 facilitate the welding of the first side panel 21 and the second side panel 22 to the top panel 25 and the panel 24, respectively. Furthermore, the top panel 25 and the panel 24 are integrally formed and are roughly in the shape of a bent plate. In one embodiment, the back plate 23, the panel 24, the top plate 25, and the bottom plate are part of the steel above the frame, the opening is opened on the square steel, and the first side plate 21 and the second side plate 22 are fixedly connected to the square steel by welding.

[0030] Continue to see Figure 1 and Figure 2In one or more embodiments, the mounting frame 2 is provided with guide slots 27, which are located on the first side panel 21 and the second side panel 22. Specifically, the guide slots 27 extend in the vertical direction and mate with the guide rod 12. The guide rod 12 slides along the guide slots 27, thereby switching between a hidden state and an extended state. The hidden state means that the main body 11 is hidden within the accommodating cavity and does not protrude from the top panel 25 of the mounting frame 2; the extended state means that the main body 11 extends out of the accommodating cavity. It is understood that when the guide slide 12 is at the bottom of the guide slot 27, the highest point of the main body 11 is still somewhat above the top plate 25. The guide slide 12 moves along the guide slot 27, gradually raising the main body 11 until its highest point is flush with the top plate 25. During this process, the rope loop 1 is hidden. The guide slide 12 continues to move along the guide slot 27, raising the highest point of the main body 11 above the top plate 25 until the guide slide 12 is at the top of the guide slot 27. During this process, the rope loop 1 is extended. When the guide slide 12 is at the bottom of the guide slot 27, a portion of the main body 11 is still visible through the opening in the panel 24, making it easier for staff to access the rope loop 1. Furthermore, the panel 24 can abut against the main body 11 to prevent the rope loop 1 from flipping over. Alternatively, the panel 24 may not abut against the main body 11, but may simply serve to shield and connect the first side panel 21 and the second side panel 22. Furthermore, the guide chute 27 includes a vertically extending lower portion 271 and an upper portion 272 connected to the lower portion 271. The width of the lower portion 271 matches that of the guide slide 12, allowing the guide slide 12 to slide up and down within the lower portion 271 and prevent it from flipping. Specifically, a contact surface 273 is formed at the bottom of the lower portion 271, which abuts against the anti-flip surface 13, thereby preventing the guide slide 12 from rotating. The width of the upper portion 272 is greater than that of the lower portion 271, allowing the guide slide 12 to flip within the upper portion 272, thereby facilitating the adjustment of the main body 11 to the appropriate angle for connection with the strapping. Furthermore, the arrangement of the panel 24 also limits the flipping angle of the main body 11, preventing it from inverting. Furthermore, the lower portion 271 extends upward at an angle. Specifically, the lower portion 271 extends upward at an angle and toward the panel 24. When the frame bumps, the rope ring 1 and the mounting frame 2 slide relative to each other, and the guide slide bar 12 slides upward along the lower half 271. When it moves to the upper half 272, it abuts against the upper half 272, thereby preventing the guide slide bar 12 from continuing to move, preventing the rope ring 1 from being too bumpy, and protecting the rope ring 1 and the mounting frame 2.

[0031] Figure 3 This is a schematic diagram of a second embodiment of a slidable tethered ring structure of the present invention. Figure 4 This is another schematic diagram of the second embodiment of the slidable tethering ring structure of the present invention. Figure 3 and Figure 4Another embodiment of a slidable tie ring structure of the present invention is illustrated. The difference between the two is that the second embodiment eliminates the panel 24, lengthens the first and second side panels 21, 22, and provides a tie post 28 between the first and second side panels 21, 22. Specifically, through-holes are provided in the first and second side panels 21, 22, and the ends of the tie post 28 are fixed within the through-holes of the first and second side panels 21, 22. When connecting the tie rope, the tie rope can be connected to the rope ring 1 or to the tie post 28 as needed, making the tie ring structure suitable for a wider range of work scenarios and more adaptable.
