Description
Technical Field
[0001] The utility model relates to the technical field of shelves, in particular to a portable, stretchable and foldable simple shelf. Background Technique
[0002] Pipes are widely used in many fields such as construction and cable laying. Pipes need to be stacked on shelves during construction sites, warehouses, and transportation. Traditionally, on construction sites, pipes are basically directly stacked on the ground, forming triangular stacks. There are problems such as scattered and uneven placement, large floor area, and extremely unstable. In order to ensure their stability, pipes are generally tied up, but the tied pipes are not convenient to pick up. This situation also exists in warehouse storage. During the transportation of pipes, if the guardrail of the truck bed used for transportation is relatively low, the number of pipes transported is small and the carrying capacity is poor. Therefore, the transportation cost is relatively high. In addition, traditional shelves are basically welded multi-layer integral structures, such as the shelves used in hardware stores, which are inconvenient to move and have a low storage capacity. Therefore, we design a portable, stretchable and foldable simple shelf to solve the above problems. Content of the Utility Model

[0031] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0034] As Figures 1-5 shown, the present utility model provides a technical solution: a portable, stretchable and foldable simple shelf, which is characterized by comprising two parallel first bottom beams 1, two parallel second bottom beams 2 and four parallel vertical beams 3. Fixed first grooves 15 are provided on both side edges at the two ends of the first bottom beam 1, and first hooks 20 are fixed at both ends of the second bottom beam 2. The first hooks 20 are inserted into the first grooves 15, so that the first bottom beam 1 and the second bottom beam 2 are perpendicular to each other in the horizontal plane, forming a bottom frame structure. Assembly grooves 12 are provided at both ends of the first bottom beam 1, and the vertical beams 3 are vertically fixed in the assembly grooves 12 through fixing screws 14. The connection between the first bottom beam 1 and the vertical beam 3 is connected by a hinge 7, and the hinge 7 is located at the upper end of the frame structure.
[0035] When disassembly is required, the fixing screws 14 are removed, and the first bottom beam 1 and the second bottom beam 2 can be folded and combined through the hinge 7. The first bottom beam 1 and the second bottom beam 2 can be disassembled and stacked separately, reducing the space occupied by the shelf and facilitating carrying.
[0036] Further, the first bottom beam 1 includes a first bottom beam a 10 and a first bottom beam b 11. Both the first bottom beam a 10 and the first bottom beam b 11 are hollow structures with one end open. A number of first connection holes 13 are equidistantly arranged on the first bottom beam a 10 and the first bottom beam b 11. A splicing beam 5 is inserted into the first bottom beam a 10 and the first bottom beam b 11. A number of second connection holes 50 are equidistantly arranged on the splicing beam 5. The first bottom beam a 10, the first bottom beam b 11 and the splicing beam 5 are fixed by screws passing through the first connection holes 13 and the second connection holes 50.
[0037] By adjusting the positional relationship between the splicing beam 5 and the first bottom beam a 10 and the first bottom beam b 11, the overall length of the first bottom beam 1 is adjusted, and further the ability of the shelf to store pipes is adjusted, which is convenient to use.
[0038] Further, fixed second grooves 33 are provided inside the vertical beams 3. A reinforcing beam 4 is inserted into two opposite second grooves 33. The reinforcing beam 4 has the same structure as the second bottom beam 2. Second hooks 40 are provided at both ends of the reinforcing beam 4. The second hooks 40 are inserted into the second grooves 33. The reinforcing beam 4 reinforces the vertical beams 3 and improves the overall stability of the shelf.
[0039] Furthermore, the vertical beam 3 includes a first vertical beam 30, a second vertical beam 31 and a third vertical beam 32. The second vertical beam 31 is sleeved in the first vertical beam 30, and the third vertical beam 32 is sleeved in the second vertical beam 31. The upper end of the first vertical beam 30, the upper and lower ends of the second vertical beam 31 and the lower end of the third vertical beam 32 are all provided with two vertically distributed connection holes. The second vertical beam 31 is fixed to the upper end of the first vertical beam 30 by screws passing through the connection holes, and the third vertical beam 32 is fixed to the upper end of the second vertical beam 31.
[0040] Furthermore, an anti-slip plate 34 is provided at the upper end of the first vertical beam 30, that is, the upper end of the first vertical beam 30 is a surrounding structure.
[0041] When the shelf needs to be dismantled, the connecting screws on the first vertical beam 30, the second vertical beam 31, and the third vertical beam 32 can be removed, and the third vertical beam 32 can slide down and be stored in the second vertical beam 31, and the second vertical beam 31 can slide down and be stored in the first vertical beam 30, and the second vertical beam 31 and the third vertical beam 32 can be limited by the anti-drop plate 34, which can greatly reduce the space occupied and facilitate the carrying of the shelf.
[0042] Furthermore, the side of the assembly groove 12 on the first bottom beam 1 is threadedly connected and fixed with a lifting ring 6, that is, the lifting ring 6 is located outside the four corners of the bottom of the shelf. When lifting is required, the shelf and the built-in pipes can be connected for one-time loading and unloading. In order to ensure the stability of the pipes, the pipes can be bundled and reinforced in advance to ensure the safety of lifting.
[0043] If Figure 6 As shown in the figure, pipes can be laid flat inside the shelf. Compared with the traditional stacking method, such as triangular stacking, the same pipe stacking height and floor space can store three times the number of pipes. The pipes are stably stored and easy to access, which is suitable for pipe storage on construction sites and warehouses.
[0044] If Figure 7 As shown in , when using a semi-trailer to transport pipes, if the semi-trailer's bucket guardrail is relatively low, the loading capacity of the semi-trailer for transporting pipes can be increased by using the three-stage stretching heightening structure of the first vertical beam 30, the second vertical beam 31, and the third vertical beam 32 without exceeding the height or weight, thereby reducing the transportation cost of the pipes.
[0045] If Figure 8 As shown in , by releasing the connection between the first bottom beam a10 and the first bottom beam b11, half of the shelf structure can be used against the wall. The distance between half of the shelf structure and the wall can be controlled according to storage needs to adjust the storage space for flexible use.
