Description

Technical Field

[0001] This utility model relates to the field of cargo loading and unloading ramp technology, specifically a foldable portable cargo loading and unloading ramp. Background Technology

[0002] When loading goods into trucks, loading and unloading ramps are often used to transfer goods. Currently, most ramps are one-piece ramps, meaning the ramp is a single piece of slab. Not only are the ramps large in volume, making them inconvenient to remove for use or storage, but because the shape and size of the single-piece ramp are fixed, the slope of the ramp is basically fixed and cannot be adjusted when connecting the truck and the ground. Therefore, the slope cannot be adjusted according to the difficulty of loading and unloading goods, making the ramps inflexible in use. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a foldable portable cargo loading and unloading ramp. By incorporating a retractable support plate, the ramp can be rolled up into a cylindrical shape after use, reducing its size and facilitating movement and carrying. Furthermore, the support plate itself can be extended, allowing for adjustment of the ramp's slope. Users can flexibly adjust the ramp according to their loading needs, reducing the difficulty of loading and unloading goods and solving the problems mentioned in the background art.

[0004] Technical solution

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a foldable portable cargo loading and unloading ramp, comprising several bearing plates, the bearing plates being divided into a front section, a telescopic section and a rear section, the front section and the telescopic section being fixedly connected, and the telescopic section being able to extend or be stored in the rear section;

[0006] Adjacent load-bearing plates are rotatably connected by hinge seats, which are fixedly installed at the bottom of the front and rear sections respectively. The combined load-bearing plates can be rolled into a near-cylindrical polygonal shape.

[0007] Furthermore, when the telescopic section is housed in the rear section, the front and rear sections are connected and closed to each other.

[0008] Furthermore, a limit block is fixedly connected to the movable end of the telescopic section, and the limit block is slidably connected to the inner side of the rear section.

[0009] Furthermore, when the telescopic section is fully retracted inside the rear section, the telescopic section is fixed in the rear section by a positioning pin.

[0010] Furthermore, when the ramp is in its unfolded state, the front and rear facing sections of adjacent load-bearing plates abut against each other, and the upper surfaces of the load-bearing plates are on the same plane.

[0011] Furthermore, a top overlapping plate and a bottom overlapping plate are respectively connected to the load-bearing plates at both ends of the ramp, and the top overlapping plate and the bottom overlapping plate are rotatably connected to the load-bearing plate through hinged seats.

[0012] The beneficial effects of this utility model are as follows:

[0013] By incorporating a retractable support plate, the ramp can be rolled up into a cylindrical shape after use, reducing its size and facilitating movement and transport. Furthermore, the support plate itself can be extended. When loading and unloading lighter goods, the shorter support plate allows for a steeper ramp, reducing personnel movement time and improving loading efficiency. When loading and unloading heavier goods, the width of the support plate can be extended, increasing the overall length of the ramp and making it gentler, thus reducing the difficulty of loading and unloading heavy goods.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] See Figures 1-6A foldable portable cargo loading and unloading ramp includes several support plates 1. The support plates 1 are divided into a front section 101, a telescopic section 102 and a rear section 103. The front section 101 and the telescopic section 102 are fixedly connected, and the telescopic section 102 can extend or be stored in the rear section 103.

[0023] Adjacent support plates 1 are rotatably connected by hinge seats 2. The hinge seats 2 are fixedly installed at the bottom of the front section 101 and the rear section 103 respectively. The combined support plates 1 can be rolled into a polygonal shape that is approximately cylindrical.

[0024] In this solution: When loading goods into trucks, loading and unloading ramps are frequently used to transfer goods into the trucks. Currently, most of the ramps used are one-piece ramps, which are large in size and inconvenient to remove or store. Furthermore, because the shape and size of the one-piece ramp are fixed, the slope of the ramp is basically fixed and cannot be adjusted when connecting the truck and the ground. Therefore, the slope cannot be adjusted according to the difficulty of loading and unloading goods, and the ramp is not flexible enough in use.

[0025] like Figure 1 , Figure 2 , Figure 4 As shown, by setting a retractable support plate 1, the ramp can be retracted into a cylindrical shape after use, reducing the size of the ramp and making it easier to move and carry. In addition, the support plate 1 itself can be extended. When loading and unloading lighter goods, the support plate 1 is shorter overall, which can increase the slope of the ramp, making the ramp steeper, reducing the time personnel spend moving on the ramp, and improving loading efficiency. When loading and unloading heavier goods, the width of the support plate 1 can be extended, thereby extending the overall length of the ramp, making the ramp gentler, and reducing the difficulty of loading and unloading heavy goods.

[0026] When the telescopic section 102 is housed in the rear section 103, the front section 101 and the rear section 103 are connected and closed to each other.

[0027] In this embodiment, the width of the support plate 1 is adjusted by extending or retracting the telescopic section 102 in the rear section 103. When the telescopic end is retracted in the rear section 103, the closure of the front section 101 and the rear section 103 can keep the surface of the support plate 1 flat and reduce the resistance of the trolley wheels for transporting goods on the support plate 1.

[0028] The movable end of the telescopic section 102 is fixedly connected to the limiting block 3, and the limiting block 3 is slidably connected inside the rear section 103.

[0029] In this embodiment: as follows Figure 5 , Figure 6As shown, the limiting block 3 can limit the position of the telescopic segment 102 in the rear segment 103. When the telescopic segment 102 moves to its maximum extendable distance in the rear segment 103, it prevents the telescopic segment 102 from falling out of the rear segment 103. It should be noted that a stop block is also provided in the rear segment 103 to block the limiting block 3 and prevent the limiting block 3 from falling out of the rear segment 103. The extension length of the telescopic segment 102 in the rear segment 103 should not be too long. The extension distance of the telescopic segment 102 in the rear segment 103 should be about half the length of the rear segment 103. At the same time, it still refers to Figure 5 , Figure 6 The rear section 103 is not a single-layer thin plate, but a double-layer plate. Therefore, the rear section 103 itself has higher strength than the traditional single-layer plate. After the telescopic section 102 extends out of the rear section 103, the limiting block 3 still has a large contact area in the rear section 103. The rear section 103 can provide relatively stable support for the telescopic section 102 and the limiting block 3. If the extension length of the telescopic section 102 from the rear section 103 is too long, the telescopic section 102 will need to occupy a large volume in the rear section 103. Therefore, the width of the limiting block 3 will inevitably be reduced, resulting in a smaller contact area between the limiting block 3 and the rear section 103. The support force of the limiting block 3 on the rear section 103 will be greatly reduced, affecting the strength of the bearing plate 1.

[0030] When the telescopic section 102 is fully retracted inside the rear section 103, the telescopic section 102 is fixed in the rear section 103 by the positioning pin 4.

[0031] In this embodiment: as follows Figure 5 , Figure 6 As shown, when the telescopic section 102 is in the rear section 103, the positioning pin 4 can fix the telescopic section 102 and the limiting block 3 in the rear section 103, preventing the telescopic section 102 from sliding in the rear section 103 after being stored in it, and keeping the position of the telescopic section 102 in the rear section 103 stable.

[0032] When the ramp is in its extended state, the front section 101 and the rear section 103 of the adjacent bearing plates 1 are in contact with each other, and the upper surfaces of the bearing plates 1 are on the same plane.

[0033] In this embodiment: during the use of the ramp, the rolled-up support plate 1 unfolds. When the support plates 1 are unfolded on the same plane, the front section 101 and the rear section 103 of the adjacent support plates 1 abut against each other, thereby preventing the adjacent support plates 1 from continuing to flip and maintaining the unfolded state of the ramp. Furthermore, the front section 101 and the rear section 103 are in surface contact, which can increase the contact area between the front section 101 and the rear section 103 and improve the stability when the adjacent support plates 1 are in contact.

[0034] A top overlapping plate 5 and a bottom overlapping plate 6 are respectively connected to the bearing plate 1 at both ends of the ramp. The top overlapping plate 5 and the bottom overlapping plate 6 are rotatably connected to the bearing plate 1 through a hinge seat 2.

[0035] In this embodiment: the top overlapping plate 5 is used to hang on the truck, and the bottom overlapping plate 6 is placed on the ground to facilitate the connection between the truck and the ground via the ramp. The top overlapping plate 5 and the bottom overlapping plate 6 are connected to the bearing plate 1 through the hinge seat 2, so that the top overlapping plate 5 and the bottom overlapping plate 6 can rotate and roll up like the bearing plate 1, reducing the overall volume of the bearing plate 1 after rolling up.

[0036] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
