Description
Technical Field
[0001] The utility model relates to the technical field of shelves, in particular to a portable, flippable and foldable simple shelf. Background Art
[0002] Pipes are widely used in many fields such as construction and cable laying. Pipes need to be stacked on shelves in construction sites, warehouses, and during transportation. Traditionally, on construction sites, pipes are basically stacked directly on the open space to form piles of triangular stacks, which are scattered and uneven, occupy a large area, and are extremely unstable. In order to ensure their stability, pipes are generally bundled, but the bundled pipes are not convenient to use. This situation also exists in warehouse storage. During the transportation of pipes, if the guardrail of the transport vehicle used is shorter, the number of pipes transported is small and the carrying capacity is poor, so the transportation cost is relatively high. In addition, traditional shelves are basically welded multi-layer integrated structures, such as hardware store shelves, which are inconvenient to move and have a low storage capacity. Therefore, we designed a portable, flip-foldable simple shelf to solve the above problems. Utility Model Content

[0037] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0040] like Figure 1-8 As shown, the utility model provides a technical solution: a portable, flippable and foldable simple shelf, comprising two parallel first bottom beams 1, two parallel second bottom beams 2 and four parallel vertical beams 3, the first bottom beams 1 and the second bottom beams 2 are vertically arranged in pairs in a horizontal plane to form a bottom frame structure, and the first bottom beam 1 and the second bottom beam 2 are connected at a connection point through a first hinge 7, the first hinge 7 is located at a corner position inside the frame structure, the second bottom beam 2 comprises a second bottom beam a20 and a second bottom beam b21, the second bottom beam a20 and the second bottom beam b21 are connected through a third hinge 9, the third hinge 9 is located outside the frame structure, both ends of the first bottom beam 1 are provided with assembly grooves 12, the vertical beams 3 are vertically fixed in the assembly grooves 12 by fixing screws 14, the first bottom beam 1 and the vertical beams 3 are connected at a connection point through a second hinge 8, and the second hinge 8 is located at the upper end of the frame structure.
[0041] When disassembly is required, remove the fixing screws 14, the first bottom beam 1 and the second bottom beam 2 can be folded and combined by the first hinge 7, the first bottom beam 1 and the vertical beam 3 can be folded and combined by the second hinge 8, and the second bottom beam a20 and the second bottom beam b21 can be folded and combined by the third hinge 9, thereby reducing the space occupied by the shelf and facilitating carrying.
[0042] Furthermore, the first bottom beam 1 includes a first bottom beam a10 and a first bottom beam b11, both of which are hollow structures with one end open, and a plurality of first connecting holes 13 are evenly spaced on the first bottom beam a10 and the first bottom beam b11, and a splicing beam 5 is inserted into the first bottom beam a10 and the first bottom beam b11, and second connecting holes 50 are evenly spaced on the splicing beam 5, and the first bottom beam a10, the first bottom beam b11, and the splicing beam 5 are fixed by screws passing through the first connecting holes 13 and the second connecting holes 50.
[0043] By adjusting the positional relationship between the splicing beam 5 and the first bottom beam a10 and the first bottom beam b11, the overall length of the first bottom beam 1 can be adjusted, thereby adjusting the ability of the shelf to store pipes, which is convenient to use.
[0044] Furthermore, a fixed groove 33 is provided on the inner side of the vertical beam 3, and reinforcing beams 4 are inserted in two opposite grooves 33. Hooks 40 are provided at both ends of the reinforcing beams 4, and the hooks 40 are inserted into the grooves 33. The reinforcing beams 4 reinforce the vertical beams 3 to improve the overall stability of the shelf.
[0045] 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 ends of the first vertical beam 30 and the second vertical beam 31 are provided with a slide groove 34, and the lower ends of the second vertical beam 31 and the third vertical beam 32 are provided with two vertically distributed connecting holes 35. The connecting holes 35 at the lower ends of the second vertical beam 31 and the third vertical beam 32 are connected with a rotating rod 36, and the rotating rod 36 is placed in the slide groove 34. Limiting parts are provided at both ends of the rotating rod 36, and the limiting parts are located on the outside of the slide groove 34. Fastening screws are connected to the connecting holes 35 at the upper ends of the second vertical beam 31 and the third vertical beam 32. When the shelf needs to be dismantled, the fastening screws in the connecting holes 35 at the upper ends of the second vertical beams 31 and the third vertical beams 32 can be removed, and the third vertical beam 32 can be lifted upward to drive the rotating rod 36 connecting the second vertical beams 31 and the third vertical beams 32 to move upward to the top in the sliding groove 34 at the upper end of the second vertical beam 31, and the third vertical beam 32 can be flipped over to be stored in the second vertical beam 31. The second vertical beam 31 can be flipped over and folded and stored in the first vertical beam 30 by the same operation method, thereby reducing the space occupied by the shelf and facilitating carrying.
[0046] Furthermore, a lifting ring 6 is fixedly connected to the outer side of the assembly groove 12 on the first bottom beam 1 through a threaded connection, that is, the lifting ring 6 is located on the outer side of 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.
[0047] like Fig. 9 As shown, pipes can be laid flat inside the shelf. Compared with traditional stacking methods, 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.
[0048] like Fig.10 As shown, when a semi-trailer is used to transport pipes, if the semi-trailer's cargo box guardrail is relatively low, the loading capacity of the semi-trailer for transporting pipes can be increased by using the three-level flip-up height-increasing 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.
[0049] like Fig.11 As shown, 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.
[0050] like Fig.12 As shown, the shelf is in a folded and disassembled state, which occupies a small space and is convenient to carry to where it is needed, such as a construction site, a warehouse, etc., and then assembled on site. The overall design of the utility model is simple in structure, flexible in use, and easy to assemble, and is suitable for popularization and use.
[0051] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
