Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically to a shelf for a ripening cold storage. Background Technology

[0002] The humidity and temperature inside the ripening cold storage are high. The shelves are usually made of high-quality cold-rolled steel, stainless steel or galvanized steel sheet, and have undergone special treatments such as hot-dip galvanizing and powder coating to enhance low temperature resistance and corrosion resistance, prevent rust and corrosion, and ensure long-term stable use in harsh environments. The existing ripening cold storage racks are mainly composed of the rack body and supporting columns. The supporting columns are used to connect the upper and lower racks and bear the weight. When stacking, the lower rack must be fixed first, and then the four columns must be manually inserted into the mounting holes of the lower rack one by one. Finally, the upper rack is hoisted and fitted with the columns. When storing or disassembling, the operation must be reversed. First, the upper rack is hoisted away, and then the four columns are disassembled and pulled out one by one. Finally, they are stored in categories.

[0003] The above-mentioned operation has obvious drawbacks. Each upright needs to be installed or dismantled individually, a cumbersome process that leads to low efficiency. Furthermore, the low-temperature environment of cold storage further reduces operational flexibility and prolongs the process. Additionally, individual upright handling and storage makes them prone to loss, damage, or misalignment, increasing labor intensity and impacting the subsequent use of the shelving. Therefore, there is an urgent need to improve the existing shelving structure, resolve the cumbersome upright handling issue, and enhance the convenience of stacking and storage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shelf for a ripening cold storage facility, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shelf for a ripening cold storage, comprising a base frame and four supporting legs; The four support legs are respectively vertically installed at the four corners of the base frame, and the top of each of the four support legs is hinged to a column through a hinge shaft, so that the columns on the left and right sides can rotate and fold in opposite directions on the ZY plane. A connecting rod is provided between two opposing columns to connect the two opposing columns; Furthermore, a connecting structure is provided between the two columns to fix the columns to their hinged support legs; The connecting structure includes sleeves respectively fitted on the outer sides of the four columns, and the sleeves are also fitted on the outer sides of the support feet. A connecting plate is provided between two of the sleeves, and a lifting structure is provided between the two columns to pull up the two sleeves at the same time.

[0006] The length and width of the inner wall of the sleeve in the XY plane can be adapted to the length and width of the column and the support foot in the XY plane, respectively.

[0007] The bottom end of the sleeve is folded outward to form a flared section.

[0008] Furthermore, the length and width of the flared portion on the XY plane are greater than the length and width of the supporting foot on the XY plane, respectively.

[0009] The lifting structure includes a horizontal plate installed between two opposing columns, a tie rod extending through the interior of the horizontal plate, the bottom end of the tie rod being connected to the horizontal plate, and a pull ring being rotatably connected to the top end of the tie rod.

[0010] A spring is provided between the connecting plate and the cross plate, and is sleeved on the outside of the pull rod.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: This ripening cold storage rack, through the linkage of the hinge and connection structure, allows the uprights to be folded and unfolded simply by pulling the rings, eliminating the need to disassemble and assemble each upright individually, thus greatly reducing the number of operation steps. The flared end of the sleeve and the automatic reset function of the spring reduce the difficulty of operation for workers in low-temperature environments, avoiding problems such as reduced operational flexibility and increased time consumption caused by low temperatures, and improving the efficiency of rack disassembly, assembly and stacking.

[0014] 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.

[0015] Please see Figure 1-3In this embodiment, a shelf for ripening cold storage is provided. Through the interconnected uprights 3 and connecting structure 4, it solves the problem of cumbersome disassembly and assembly of traditional shelves and adapts to the high-efficiency storage needs in the low-temperature environment of cold storage. Its structure is mainly composed of base frame 1, support legs 2, uprights 3, connecting structure 4, and connecting rod 5. All components work together to achieve folding and unfolding. Specifically, the base frame 1 is the basic load-bearing frame of the shelf, made of high-strength metal. Four support legs 2 are vertically installed at its four corners. The support legs 2 are also made of metal and are welded to the base frame 1 to form a stable support structure. The tops of the four support legs 2 are all hinged to the uprights 3 through hinge shafts, so that the uprights 3 on the left and right sides can rotate and fold in opposite directions on the ZY plane around the hinge shafts. When not in use, the uprights 3 can be folded towards the center of the base frame 1 to reduce the shelf's footprint and facilitate storage. When in use, the uprights 3 can be rotated to a state perpendicular to the support legs 2 to serve as a support carrier for stacking the upper shelves.

[0016] Furthermore, a connecting rod 5 is fixed between the two opposing columns 3. The connecting rod 5 is horizontally set and its two ends are welded or bolted to the columns 3 respectively, so that the opposing columns 3 form a synchronous linkage structure, ensuring that the folding or unfolding actions of the left and right columns 3 are consistent.

[0017] Furthermore, a connecting structure 4 is provided between the two opposing columns 3 to fix the column 3 to the hinged support leg 2, preventing the column 3 from rotating under load. The connecting structure 4 includes a sleeve 401, a connecting plate 402, and a lifting structure; The four sleeves 401 are respectively fitted onto the outside of the four columns 3 and simultaneously onto the outside of the support feet 2. The length and width of the inner wall of the sleeve 401 in the XY plane are adapted to the dimensions of the columns 3 and the support feet 2 in the XY plane, ensuring that the sleeve 401 can slide up and down along the outer walls of the columns 3 and the support feet 2 without significant shaking during the sliding process. The bottom end of the sleeve 401 is folded outward to form a flared part 4011. The length and width of the flared part 4011 in the XY plane are greater than the corresponding dimensions of the support feet 2, which facilitates the quick insertion of the sleeve 401 into the support feet 2 and reduces the difficulty of operation.

[0018] In detail, the lifting structure is installed between two opposing columns 3, including a horizontal plate 403, a tie rod 404, a pull ring 405, and a spring 406; The horizontal plate 403 is fixed horizontally between two opposing columns 3 and is located above the sleeve 401; the pull rod 404 passes through the interior of the horizontal plate 403, with its bottom end fixedly connected to the connecting plate 402, and its top end extending out of the horizontal plate 403 and rotatably connected to a pull ring 405. Workers can pull or press the pull ring 405 to drive the pull rod 404 and the connecting plate 402 to move up and down synchronously. Moreover, the spring 406 is sleeved on the outside of the tie rod 404 and located between the connecting plate 402 and the cross plate 403. In its natural state, the spring 406 is in a compressed state. Through its elastic force, it pushes the connecting plate 402 and the sleeve 401 downward, so that the sleeve 401 tightly fits the column 3 and the support foot 2, thereby enhancing the fixing effect.

[0019] It should be noted that, in combination Figure 2 As shown in the design, the two right-side support legs 2 are lower in height along the Z-axis than the two left-side support legs 2, creating a height difference layout for the support legs 2. This design is specifically adapted to the folding and storage needs of the left and right uprights 3. When the uprights 3 are rotated and folded in opposite directions on the ZY plane around the hinge axis, because the right-side support legs 2 are lower, the right-side upright 3 will naturally be positioned below the left-side upright 3 after rotation, with the two stacked vertically. The working principle of the above embodiments is as follows: (1) In the initial state, the column 3 is folded close to the base frame 1. The worker pulls the pull ring 405 upwards. The pull ring 405 drives the pull rod 404 to move upwards along the horizontal plate 403. The pull rod 404 pulls the connecting plate 402 upwards in sync. The connecting plate 402 drives the two opposite sleeves 401 to overcome the compression force of the spring 406 and slide upwards along the outer wall of the column 3. The columns 3 on the left and right sides are rotated around the hinge axis on the ZY plane to a state perpendicular to the support foot 2. At this time, the column 3 and The support feet 2 are arranged in a straight line and can serve as the support carrier for the upper shelf. When the pull ring 405 is released, the spring 406 returns to its original deformation and generates a downward elastic force to push the connecting plate 402 and the sleeve 401 to slide down along the outer wall of the upright 3 until the sleeve 401 re-fits the upright 3 and the support feet 2. Since the inner wall size of the sleeve 401 is adapted to both, the rotation of the upright 3 around the hinge axis can be restricted after fitting, thus fixing the upright 3 and the support feet 2. The upright is unfolded and fixed, and the shelf is put into use.

[0020] (2) When the shelf is idle and needs to be stored, the staff will pull the ring 405 upward again, and the connecting plate 402 and sleeve 401 will slide upward through the pull rod 404, disengaging from the support foot 2, releasing the rotation restriction on the upright 3, and the spring 406 will be further compressed to store elastic potential energy, and the uprights 3 on the left and right sides will be rotated and folded towards the center of the base frame 1. Due to the linkage of the connecting rod 5, the opposite uprights 3 will rotate synchronously until the uprights 3 are close to the upper surface of the base frame 1, completing the folding and storage, and reducing the area occupied by the shelf.
