Description

Technical Field

[0001] The utility model relates to the field of truck spare parts, in particular to a limit hinge and a cargo compartment. Background Art

[0002] The cargo compartment railing includes side panels and tail panels, and the cargo compartment railing is often connected to the compartment floor through multiple hinges. When spraying the topcoat on the cargo compartment railing, the inside of the cargo compartment railing will be sprayed first, then the cargo compartment railing will be erected, and finally the outside of the cargo compartment railing will be sprayed. Because the cargo compartment railing is connected to the cargo compartment floor through hinges, the cargo compartment railing will tilt inward when it is erected, causing damage to the paint on the bottom or inside of the cargo compartment railing. In order to prevent the cargo compartment railing from tilting inward when painting, the hinge is required to have a certain limiting function to prevent the paint surface from being scratched. At the same time, a few railing trucks on the market have the function of flattening the tail panel, and most of them have side panels that can be laid flat. In order to meet this demand of some users, it is necessary to provide a cargo compartment limiting hinge that can limit the railing and facilitate its laying flat. Utility Model Content

[0003] The utility model aims to provide a position-limiting hinge and a cargo compartment, in order to provide a cargo compartment position-limiting hinge which can limit the position of a sideboard and facilitate the cargo compartment to be laid flat.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a limit hinge, the limit hinge includes a pin shaft, a limit pin and a hinge unit, the hinge unit includes a first hinge and a second hinge rotatably connected to the pin shaft, the pin shaft is provided with a socket, the first hinge and the second hinge both include a connecting portion and a rotating ring, a fan-shaped groove is provided on one side of the rotating ring of the first hinge, the limit pin can be inserted into the socket and is located in the fan-shaped groove, and when the first hinge rotates clockwise or counterclockwise, the limit pin abuts against the side wall of the fan-shaped groove for limiting.

[0005] The beneficial effects of this program are:

[0006] Through the above arrangement, the first hinge and the second hinge are fixedly connected to the cargo compartment floor and the tail plate (or side plate) respectively. Taking the fixed connection between the first hinge and the tail plate as an example, when the tail plate rotates, the rotation of the first hinge revolves around the pin shaft. When the limit pin is not inserted into the socket, the first hinge can rotate significantly around the pin shaft, which will cause the railing to tilt inward when painting. When in use, the limit pin is inserted into the socket. By adjusting the position of the limit pin, when the railing is in a vertical state, the side wall of the fan-shaped groove is against the limit pin, so that it cannot continue to rotate and thus avoid tilting inward; when the railing is to be horizontal, rotate the first hinge in the opposite direction so that the other side wall of the fan-shaped groove is against the limit pin from another direction, so that it cannot continue to rotate and thus the railing is leveled; when the railing needs to be completely lowered, just remove the limit pin.

[0007] Through the cooperation of the limit pin and the fan-shaped groove, the movement range of the railing can be flexibly controlled. When the limit pin is in the socket, the railing can be rotated between the vertical position and the horizontal position. When the railing is in the vertical position, it can prevent the cargo compartment railing from tilting inward, solve the problem of paint damage caused by the inward tilt of the cargo compartment railing, avoid the tedious operation of secondary repainting, and at the same time realize the flattening function of the tailgate, which is simple to operate, low cost and easy to use.

[0008] Preferably, as an improvement, the angle between the two side walls of the fan-shaped groove is 90 degrees.

[0009] The beneficial effect is: when the angle between the two side walls of the fan-shaped groove is 90 degrees, it means that when the limit pin is inserted, the rotation angle of the guardrail is strictly limited to 90 degrees. One side wall is used to limit the rotation of the guardrail in the vertical state, and the other side wall is used to limit the rotation of the guardrail in the horizontal state. Through the 90-degree limit setting, the guardrail can be accurately converted between the vertical and horizontal positions to avoid excessive tilt or angle deviation.

[0010] Another purpose of this embodiment is to provide a cargo compartment, including a limiting hinge, the cargo compartment including a cargo compartment floor and a cargo compartment side panel rotatably connected to the cargo compartment floor through a limiting hinge, the cargo compartment side panel including a tail panel and two side panels.

[0011] The beneficial effect is that the tail board and both side boards can be erected to protect the cargo. Especially during transportation, the erected side boards can prevent the cargo from falling out of the cargo compartment, improving safety.

[0012] Preferably, as an improvement, the bottom array of the cargo compartment floor has a plurality of supporting cross beams, at least two supporting longitudinal beams are fixed to the bottom of the supporting cross beams, and a reinforcing seat is welded and fixed at the connection between the supporting cross beams and the supporting longitudinal beams.

[0013] The beneficial effects are as follows: Multiple supporting crossbeams are installed at the bottom of the cargo floor, effectively dispersing the pressure exerted by the cargo on the floor and providing additional support. The combination of longitudinal and crossbeams forms a stable support network, enhancing the rigidity and strength of the floor and preventing deformation under heavy loads. The joints between the supporting crossbeams and the supporting longitudinal beams are welded with reinforcement brackets, further enhancing the strength and stability of the joint.

[0014] Preferably, as an improvement, hooks are fixed to both ends of the supporting beam.

[0015] The beneficial effect is that it is convenient to hang the vehicle shielding cloth when the vehicle stops.

[0016] Preferably, as an improvement, the side panels are connected to the cargo compartment floor via at least four position-limiting hinges, and the tail panel is connected to the cargo compartment floor via at least three position-limiting hinges. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example

[0024] The embodiment is basically as follows Figure 1-Figure 4 As shown, Figure 1 and Figure 2 The limit hinge and cargo compartment shown in the figure include a limit hinge, the limit hinge includes a pin 1, a limit pin 2 and a hinge unit, the hinge unit includes a first hinge 3 and a second hinge 4 rotatably connected to the pin 1, the pin 1 is provided with a socket 5, the first hinge 3 and the second hinge 4 both include a connecting portion 6 and a rotating ring 7, and a fan-shaped groove 8 is provided on one side of the rotating ring 7 of the first hinge 3, as shown in FIG. Figure 3 As shown, the limit pin 2 can be inserted into the socket 5 and located in the fan-shaped groove 8. When the first hinge 3 rotates clockwise or counterclockwise, the limit pin 2 and the side wall of one side of the fan-shaped groove 8 are abutted to limit the position. When the fence is in a vertical state, the side wall of the fan-shaped groove 8 is abutted against the limit pin 2, so that it cannot continue to rotate and thus avoid inward tilting; when the fence is to be in a horizontal state, the first hinge 3 is rotated in the opposite direction, so that the other side wall of the fan-shaped groove 8 is abutted against the limit pin 2 from the other direction, so that it cannot continue to rotate and thus the fence is leveled; when the fence needs to be completely lowered, it is only necessary to remove the limit pin 2. In this embodiment, the included angle between the two side walls of the fan-shaped groove 8 is 90 degrees. When the included angle between the two side walls of the fan-shaped groove 8 is 90 degrees, it means that when the limit pin 2 is inserted, the rotation angle of the fence is strictly limited to 90 degrees. One side wall is used to limit the rotation of the fence in the vertical state, and the other side wall is used to limit the rotation of the fence in the horizontal state. Through the 90-degree limit setting, the fence can be accurately converted between the vertical and horizontal positions to avoid excessive tilt or angle deviation.

[0025] like Figure 4 As shown, the cargo compartment in this embodiment includes a cargo compartment floor and a cargo compartment side panel that is rotatably connected to the cargo compartment floor via a limit hinge. The cargo compartment side panel includes a tail plate 9 and two side panels 10. The tail plate 9 and the two side panels 10 can be erected to protect the cargo. In particular, during transportation, the erected side panels can prevent the cargo from falling from the cargo compartment, thereby improving safety. The bottom array of the cargo compartment floor has multiple supporting beams 11. At least two supporting longitudinal beams 12 are welded and fixed to the bottom of the supporting beams 11. A reinforcing seat 13 is also welded and fixed at the connection between the supporting beams 11 and the supporting longitudinal beams 12. The beams can effectively disperse the pressure exerted by the cargo on the floor and provide additional support. The combination of the supporting longitudinal beams 12 and the supporting beams 11 forms a stable support network, which enhances the rigidity and strength of the floor and prevents the floor from deforming under heavy load. A reinforcing seat 13 is welded and fixed at the connection between the supporting beams 11 and the supporting longitudinal beams 12, further improving the strength and stability of the connection. In this embodiment, hooks 14 are fixed to both ends of the support beam 11 to facilitate hanging the vehicle tarpaulin when the vehicle is stopped. The side panels 10 are connected to the cargo floor via at least four limit hinges, of which five are provided in this embodiment. The tailgate 9 is connected to the cargo floor via at least three limit hinges, of which three are provided in this embodiment.

[0026] The specific implementation process is as follows:

[0027] Through the above arrangement, the first hinge 3 and the second hinge 4 are fixedly connected to the cargo compartment floor and the tail plate 9 (or side plate 10) respectively. Taking the fixed connection between the first hinge 3 and the tail plate 9 as an example, when the tail plate 9 rotates, the rotating ring 7 of the first hinge 3 rotates around the pin shaft 1. When the limit pin 2 is not inserted into the socket 5, the first hinge 3 can rotate significantly around the pin shaft 1, which will cause the railing to tilt inward when painting. When in use, the limit pin 2 is inserted into the socket 5. By adjusting the position of the limit pin 2, when the railing is in a vertical state, the side wall of the fan-shaped groove 8 is against the limit pin 2, so that it cannot continue to rotate and thus avoid tilting inward; when you want the railing to be in a horizontal state, rotate the first hinge 3 in the opposite direction so that the other side wall of the fan-shaped groove 8 is against the limit pin 2 from another direction, so that it cannot continue to rotate and thus realize the flattening of the railing; when the railing needs to be completely lowered, you only need to remove the limit pin 2.

[0028] Through the cooperation of the limit pin 2 and the fan-shaped groove 8, the movement range of the guardrail can be flexibly controlled. When the limit pin 2 is in the socket 5, the guardrail can be rotated between the vertical position and the horizontal position. When the guardrail is in the vertical position, it can prevent the cargo compartment guardrail from tilting inward, solve the problem of paint damage caused by the inward tilt of the cargo compartment guardrail, avoid the tedious operation of secondary repainting, and at the same time realize the flattening function of the tail plate 9, which is simple to operate, low cost and easy to use.
