Description

Technical Field

[0001] The utility model relates to the field of trailer parts, in particular to a flippable hitch 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] In order to improve or solve the technical problem in the prior art that the hitch ring protrudes from the upper surface of the frame and interferes with the loading of goods, the present invention provides a reversible hitch ring structure. The hitch ring structure includes: a rope ring, including a main body and a guide column mounted on the main body; a mounting frame, formed with a receiving cavity for accommodating the rope ring; the mounting frame includes two side panels and a limit stopper mounted on the two side panels; a guide slot matching the guide column is provided on the two side panels, and the guide column is slidably and reversibly arranged in the guide slot; when the guide column is located at the lower end of the guide slot, the distance between the central axis of the guide column and the limit stopper is less than the reversal radius of the rope ring; and when the guide column is located at the upper end of the guide slot, the distance between the central axis of the guide column and the limit stopper is greater than the reversal radius of the rope ring.

[0006] The utility model discloses a reversible hitch ring structure, comprising a rope ring and a mounting frame. The rope ring comprises a main body and a guide post, and the mounting frame comprises a side plate and a limit stop. The side plate is provided with a guide slot for the guide post to slide and flip. When the guide post is at the lower end of the guide slot, the main body faces downward, and the rope ring is hidden in a receiving cavity to avoid interfering with cargo loading. At the same time, the distance between the guide post and the limit stop is less than the rope ring's flipping radius, which can reduce the rope ring's shaking when the vehicle frame is bumpy, protecting the rope ring and the mounting frame. When the guide post is at the upper end of the guide slot, the distance between the guide post and the limit stop is greater than the rope ring's flipping radius, and the rope ring flips out of the receiving cavity, facilitating connection with the strapping belt. Through the above-mentioned arrangement, the utility model provides a flippable hitch ring structure with a guide slide groove and a limit stopper, which can hide the rope ring in the mounting frame when it is not needed to avoid interfering with cargo loading, and can lift and flip it when the rope ring is needed to extend it out of the accommodating cavity, with a simple structure and easy use; at the same time, the limit stopper can limit the rope ring, reduce the shaking of the rope ring when the frame is bumpy, and protect the rope ring and the mounting frame.

[0007] Furthermore, the limit stopper is a front baffle connected to the two side panels, and an opening is provided on the front baffle. The distance between the central axis of the guide column and the limit stopper refers to the straight-line distance between the central axis of the guide column and the lowest point of the opening.

[0008] Furthermore, the mounting frame further includes a lower baffle disposed below the main body and supporting the main body. Through the above arrangement, the lower baffle supports the main body and confines the main body between the lower baffle and the limit stopper, further reducing the shaking of the rope ring and protecting the rope ring and the mounting frame.

[0009] Furthermore, the lower baffle is arranged at an angle. Through the above arrangement, the inclined lower baffle can more conveniently limit the main body and prevent the main body from turning inward.

[0010] Furthermore, a sewage outlet is arranged on the lower baffle. Through the above arrangement, the sewage outlet can discharge sewage and debris that fall into the accommodating cavity, thereby preventing the mounting frame from being corroded and damaged.

[0011] Furthermore, a connecting section is arranged between the lower baffle and the limit stopper, and the connecting section extends horizontally. Through the above arrangement, the connecting section is convenient for supporting the main body, avoiding the main body being clamped between the lower baffle and the limit stopper, making it difficult to lift the rope ring.

[0012] Furthermore, the mounting frame further comprises a back plate connecting the two side plates, and a bottom plate connected to the limit stopper. Through the above arrangement, the back plate can enhance the connection strength of the two side plates.

[0013] Furthermore, a tying post is provided between the two side plates. 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) By setting the guide groove and the limit stopper, the rope ring can be hidden in the mounting frame when it is not needed to avoid interfering with the loading of goods, and when the rope ring is needed, it can be lifted and flipped over to extend out of the accommodating cavity, which has a simple structure and is easy to use. At the same time, the limit stopper can limit the position of the rope ring, reduce the shaking of the rope ring when the frame is bumpy, and protect the rope ring and the mounting frame;

[0016] (2) By setting a lower baffle, the lower baffle supports the main body and restricts the main body between the lower baffle and the limit stopper, further reducing the shaking of the rope ring and protecting the rope ring and the mounting frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to improve or solve the technical problem in the prior art that a hitch ring protrudes from the upper surface of a vehicle frame and interferes with cargo loading, the present invention provides a reversible hitch ring structure. The hitch ring structure comprises: a rope ring 1, comprising a main body 11 and a guide post 12 mounted on the main body 11; a mounting frame 2, forming a receiving cavity for accommodating the rope ring 1; the mounting frame 2 comprising two side panels 21 and a stopper 22 mounted on the two side panels 21; guide slots 28 matching the guide posts 12 are formed on the two side panels 21, and the guide posts 12 are slidably and reversibly arranged in the guide slots 28; when the guide posts 12 are located at the lower end of the guide slots 28, the distance between the central axis of the guide posts 12 and the stopper 22 is less than the reversal radius of the rope ring 1; and when the guide posts 12 are located at the upper end of the guide slots 28, the distance between the central axis of the guide posts 12 and the stopper 22 is greater than the reversal radius of the rope ring 1.

[0027] Figure 1 This is a schematic diagram of a first embodiment of a reversible tying ring structure of the utility model. Figure 2 This is another schematic diagram of the first embodiment of the utility model of a reversible tethering ring structure. Figure 1 and Figure 2 As shown, the utility model is a reversible 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 post 12 mounted on the main body 11. The main body 11 is roughly annular, and the guide post 12 is roughly cylindrical. Both ends of the guide post 12 protrude from the main body 11 for connection to the mounting frame 2.

[0029] Continue to see Figure 1 and Figure 2 In one or more embodiments, the mounting frame 2 includes two side panels 21, a stopper 22 mounted on the side panels 21, a back panel 23 arranged opposite the stopper 22, a lower panel 24 connected to the back panel 23, a top panel 25, and a bottom panel 26 opposite the top panel 25. The top panel 25, the two side panels 21, the back panel 23, the stopper 22, and the lower panel 24 collectively form a cavity for accommodating the rope ring 1. The bottom panel 26 is connected to the stopper 22 and is used to support the mounting frame 2. Furthermore, the back panel 23 is a generally rectangular panel, with its upper and lower sides connected to the top panel 25 and lower panel 24, respectively, and its left and right sides connected to the two side panels 21, respectively. The lower panel 24 is also a generally rectangular panel and extends obliquely downward from the back panel 23 to the stopper 22. The left and right sides of the lower panel 24 are connected to the two side panels 21, respectively. Furthermore, a drain port 27 is provided on the lower baffle 24 and is arranged on a side of the lower baffle 24 close to the limit stopper 22. Furthermore, a connecting section is provided between the lower baffle 24 and the limit stopper 22, and the connecting section extends horizontally for supporting the main body 11.

[0030] Continue to see Figure 1 and Figure 2In one or more embodiments, the limit stopper 22 is a front baffle connected to the two side panels 21, and openings are provided on the limit stopper 22 and the top panel 25 for the rope ring 1 to flip over and extend out. Specifically, the side panels 21 protrude from the top panel 25 and the limit stopper 22 at the opening to form a weld 26, and the weld 26 facilitates the welding of the side panels 21, the top panel 25, and the limit stopper 22 on the mounting frame 2. Specifically, the opening provided on the front baffle is roughly in the shape of an inverted arch, and the lowest point of the opening is higher than the connecting section in the vertical direction. Alternatively, the opening provided on the front baffle can also be set to other suitable shapes, such as a rectangular shape. Alternatively, the limit stopper 22 can also be set to other suitable shapes, such as a connecting rod, and the two ends of the connecting rod can be connected to the two side panels 21 respectively, as long as it is higher than the connecting section in the vertical direction to interfere with the flipping of the rope ring 1. Furthermore, the top plate 25, bottom plate 26, and stopper 22 are integrally formed, generally in the shape of a bent plate. In one embodiment, the top plate 25, bottom plate 26, and stopper 22 are formed as a portion of the upper steel of the vehicle frame. An opening is provided in this square steel, and the side plates 21, back plate 23, and lower baffle 24 are fixedly connected to this square steel by welding. Furthermore, guide slots 28 are provided on the side plates 21 to mate with the guide posts 12. The guide slots 28 extend in an up-down direction, and the guide posts 12 are slidably and reversibly arranged within the guide slots 28. Among them, the distance between the limit stopper 22 and the central axis of the guide column 12 refers to the straight-line distance from the central axis of the guide column 12 to the lowest point of the opening, and the flip radius of the rope ring 1 refers to the straight-line distance from the central axis of the guide column 12 to the farthest point from the main body 11; when the limit stopper 22 is a connecting rod, the distance between the limit stopper 22 and the central axis of the guide column 12 refers to the straight-line distance from the central axis of the guide column 12 to the outer peripheral wall of the limit stopper 22. When the rope ring 1 is not needed, the guide column 12 is located at the lower end of the guide slot 28, and the main body 11 abuts against the connecting section. At this time, the distance between the central axis of the guide column 12 and the lowest point of the opening is less than the flipping radius of the rope ring 1, so that the rope ring 1 interferes with the limit stopper 22 when flipping, restricting the flipping of the rope ring 1; when the rope ring 1 is needed, the guide column 12 is lifted upward along the guide slot 28, and the guide column 12 slides to the upper end of the guide slot 28. At this time, the distance between the central axis of the guide column 12 and the lowest point of the opening is greater than the flipping radius of the rope ring 1, so that the rope ring 1 can flip freely to extend out of the top plate 25 and be connected to the strapping belt.

[0031] Figure 3 This is a schematic diagram of a second embodiment of a reversible tying ring structure of the utility model. Figure 4 This is another schematic diagram of the second embodiment of the reversible tying ring structure of the present invention. Figure 3 and Figure 4Another embodiment of a reversible hitch ring structure of the present invention is illustrated. The difference between the two is that the second embodiment lengthens the two side panels 21 and sets a tying column 29 between the two side panels 21. Through holes are provided on both side panels 21, and the two ends of the tying column 29 are fixed in the through holes of the two side panels 21. When connecting the tying rope, you can choose to connect the tying rope to the rope ring 1 or to the tying column 29 as needed, so that the hitch ring structure can be used in more working scenarios and has stronger adaptability. Figure 3 and Figure 4 In the figure, the lower baffle 24 and the limit stopper 22 are not shown.

[0032] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is clearly not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and such changes or substitutions will fall within the scope of protection of the present invention.
