Abstract
Description
Technical Field
[0001] The utility model relates to the field of shelves, in particular to a stackable shelf. Background Art
[0002] In the logistics industry, shelves are a commonly used tool that can stack goods so that indoor space can be more fully utilized. When not in use, such shelves can be folded and stacked to reduce the space occupied when idle. However, such shelves have a disadvantage during use, that is, for boxes of goods stacked on the shelves, because the shelves are only fenced on both sides but not on the front and back, this causes forklifts or other lifting equipment to easily cause the goods to collapse from the front and back ports during lifting or transportation. In order to avoid collapse, our company always arranges personnel to wrap the goods stacked on the shelves with electrostatic film. Therefore, this method is not only time-consuming and labor-intensive, but also requires more cost to purchase electrostatic film. For this reason, we propose a stackable shelf. Utility Model Content

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] Embodiment 1:
[0023] like Figure 1-7 As shown, a stackable shelf comprises a load-bearing bottom plate 1 and a connecting slot 6, support structures 2 are fixedly installed at the four corners of the load-bearing bottom plate 1, left enclosures 3 are movably installed on the upper ends of two support structures 2 on one side of the load-bearing bottom plate 1, and retractable enclosure structures 4 are fixedly installed in the front and rear two columns of the left enclosure 3, and right enclosures 5 are movably installed on the upper ends of two support structures 2 on the other side of the load-bearing bottom plate 1;
[0024] The support structure 2 includes a support rod 201, a rotating shaft 202, a stacked concave base 203 and a left triangular card slot 204. The rotating shaft 202 is fixedly installed on the surface of the support rod 201, and the stacked concave base 203 is fixedly installed on the lower end of the support rod 201. A triangular card slot 204 is provided at the upper end of the support rod 201; the front and rear surfaces of the left enclosure 3 and the right enclosure 5 are fixedly installed with triangular card blocks 302, and the surfaces of the left enclosure 3 and the right enclosure 5 are located below the triangular card blocks 302. The left enclosure 3 is movably connected to the support structure 2 through the slide slot 301 at the corresponding position of the rotating shaft 202, and the right enclosure 5 is movably connected to the support structure 2 through the slide slot 301 at the corresponding position of the rotating shaft 202; the retractable enclosure structure 4 includes a fixed central axis 401, a winding wheel 402, a volute spring 403, a wire rope 404, a limit block 405, a connecting plate 406 and a connecting card cap 407. The fixed central axis 401 is fixedly installed in the left enclosure 3, and a winding wheel 402 is installed on the surface of the fixed central axis 401 through a bearing sleeve. The purpose of the bearing installation is to ensure that the winding wheel 402 can rotate and to ensure that the position of the winding wheel 402 at the plane height remains unchanged. The winding wheel 402 is provided with multiple groups, and the interior of the winding wheel 402 is fixedly connected with a spiral spring 403, and the other end of the spiral spring 403 is fixedly connected to the fixed central axis 401, and the winding arc surface of the winding wheel 402 is fixedly connected with a wire rope 404. The surfaces of the multiple wire ropes 404 are fixedly installed with a limiting baffle 405 near the connection end position with the winding wheel 402, and the other ends of the multiple wire ropes 404 are fixedly connected with the same connecting plate 406, and the surface of the connecting plate 406 is fixedly installed with a connecting card cap 407; the surfaces of the front and rear columns of the right enclosure 5 are provided with connecting card slots 6, and the connecting card cap 407 and the connecting card slot 6 are matched.
[0025] It should be noted that the utility model is a stackable shelf. When in use, the left enclosure 3 and the right enclosure 5 are flipped up and lifted up through the slide slot 301 and the rotating shaft 202, and the triangular clamping block 302 is inserted into the triangular clamping slot 204 for fixation. After fixation, the goods can be put into the load-bearing bottom plate 1 through the front and rear ports and the upper port for stacking. After the stacking is completed, the connecting plate 406 can be pulled so that the wire rope 404 wound on the winding wheel 402 is released. When it is released to the point where the connecting clamping cap 407 can just be inserted into the connecting clamping slot 6, the limit blocking piece 405 will block the wire rope 404 to prevent the wire rope 404 from being pulled out too much. At the same time, when subjected to external force, the winding wheel 402 will no longer continue to rotate, causing its internal structure to be pulled and damaged. In this way, multiple wire ropes 404 are pulled out to intercept the front and rear ports, thereby avoiding the trouble and cost of manual fixation. The setting of this structure simplifies the fixing method. During later disassembly, it is only necessary to remove the connecting cap 407 from the connecting slot 6, and then it can be recovered to the winding wheel 402 through the winding of the spiral spring 403.
[0026] The above shows and describes the basic principle and main features of the utility model and the 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 principle 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.
