Description

Technical Field

[0001] This utility model relates to the technical field of roll material holding devices, and specifically to a roll material holding rack. Background Technology

[0002] A roll material storage rack, also known as a roll material support or roll material storage rack, is an industrial storage device specifically designed for storing and managing various roll materials. The roll materials can be metal rolls (such as steel rolls, aluminum rolls, copper rolls, nickel alloy rolls, etc.) or plastic film rolls used to achieve waterproofing.

[0003] In existing technologies, the roll material is typically placed by supporting a roll material holding rack on a crossbeam, and then supporting the two ends of the crossbeam on side beams. For example, see the waterproof roll material transport rack mentioned in patent application CN216887681U. In its disclosed technical solution, a limiting groove 3 is opened on the inner side of the support plate 2, and multiple rotating shafts 16 are rotatably installed inside the limiting groove 3 at both ends. The two ends of the mounting plate 4 are fixedly connected to the rotating shafts 16, and the two ends of the waterproof roll material are placed inside the mounting groove 5 opened on the top of the mounting plate 4. See also the waterproof roll material storage rack for warehousing mentioned in patent application CN213832483U. In its disclosed technical solution... By setting a connecting rod 4 in the sliding groove 2 inside the support column 1 in a lifting and sliding manner, and fixing the two ends of the storage groove 6 to the connecting rod 4 through the horizontal plate 5, the waterproof membrane is placed separately on the storage groove 6 to realize the storage of the waterproof membrane; or see the membrane placement rack mentioned in the patent application CN108725934B, in which two symmetrically arranged mounting seats are used to install the membrane, the membrane is wound up with a roll tube, the telescopic tube passes through the roll tube and is fixed by two symmetrical mounting holes to realize the placement of the membrane.

[0004] Roll material storage racks are generally divided into placement racks and display racks. Placement racks are used for winding and placing roll materials of a specific specification or model. They are relatively large, occupy more space, and need to be stable and secure. Display racks, on the other hand, are used to showcase various specifications and models of roll materials to users. They often do not require excessive roll weight but need to wind and place multiple specifications of roll materials. Furthermore, with continuous product updates and upgrades, the displayed roll materials often need to be periodically loaded, unloaded, and replaced. This means that existing roll material storage racks are not effectively suitable for roll material display and placement purposes, mainly due to the following reasons:

[0005] 1) Existing roll material storage racks often adopt a fixed structure, which is inconvenient for loading, unloading and transportation;

[0006] 2) Existing roll material storage racks adopt a fixed structure, and the layout and quantity of the internal roll materials cannot be adjusted as needed, thus limiting their applicability;

[0007] 3) Existing roll material storage racks are bulky, take up a lot of space, and are inconvenient to transport;

[0008] 4) The loading and unloading of the rolls inside the existing roll storage racks is inconvenient and cannot effectively meet the needs of periodically loading, unloading and updating the displayed rolls.

[0009] Therefore, there is an urgent need to provide a roll material holding rack to address the defects and shortcomings of existing technologies. Utility Model Content

[0035] [First Embodiment]

[0036] like Figure 1-4The image shown is a roll material holding rack provided in the first embodiment of this utility model, as follows: Figure 1 As shown, the system includes a base frame 1, side frames 2 on both sides of the top of the base frame 1, and several crossbeams 3 detachably connected between the side frames 2. Several rolls of material 4 are mounted on the crossbeams 3. A folding structure 5 is provided on the top of the base frame 1. The side frames 2 can move up and down and rotate relative to the base frame 1 through the folding structure 5. By providing the folding structure, the two side frames can move up and down and rotate relative to the bottom base frame. Thus, during transportation, the two side frames can be stacked after being folded down by the up and down and rotation of the two side frames relative to the bottom base frame, which is convenient for transportation and handling. By providing the folding structure and several crossbeams detachably connected between the side frames, the two side frames can be stacked after being folded down. At the same time, the several crossbeams between the side frames can be disassembled, which facilitates transportation and further reduces the space occupied.

[0037] like Figure 2 and Figure 4 As shown, the folding structure 5 in this embodiment includes a mounting column 51 fixed to the top of the base frame 1 and a sliding rod 52 fixedly connected to the side frame 2. The sliding rod 52 is inserted into the mounting column 51 and can slide and rotate relative to the mounting column 51. Thus, during transportation, the two side frames can be stacked after being laid down by the lifting and rotating movements of the two side frames relative to the bottom base frame, which is convenient for transportation and handling.

[0038] like Figure 2-4 As shown, a U-shaped plate 53 is fixed to the top of the mounting column 51, and a limiting block 54 is fixed to the outer side of the side frame 2 near the U-shaped plate 53. The limiting block 54 can extend into the interior of the U-shaped plate 53 and cooperate with it to limit the movement of the slide rod 52 inside the mounting column 51 through the U-shaped plate 53; Figure 4 As shown, a circular groove 56 is provided inside the U-shaped plate 53, and a circular rod 55 that is inserted into the U-shaped plate 53 and engages with the circular groove 56 is slidably inserted inside the U-shaped plate 53. By inserting the circular rod 55 into the circular groove 56, the limiting block 54 can be limited, thereby locking the current position when the side frame 2 moves to the lowest position relative to the base frame, preventing the limiting block from sliding out of the U-shaped plate from the top due to misoperation or other reasons.

[0039] Preferably, a connecting rod 57 is fixedly connected between the front and rear round rods 55, which can drive the two round rods to slide simultaneously by pulling the connecting rod, further improving the ease of operation. As a further preferred option, an elastic element 58 is sleeved on the outer periphery of the round rod 55. The elastic element 58 can be a spring or similar material commonly used in the mechanical field. One end of the elastic element 58 is fixedly connected to the U-shaped plate 53, and the other end of the elastic element 58 is fixedly connected to the connecting rod 57. When the round rod 55 is inserted into the round groove 56, the elastic element 58 is in a naturally extended state, and when the round rod 55 is pulled out of the round groove 56, it is in a compressed state. This allows the elastic element 58 to always be located inside the round groove 56 in its natural state, thereby further improving the stability of the limiting block 54.

[0040] like Figure 2-3 As shown, several support blocks 59 are fixedly connected to the inner side of the side frame 2. The support blocks 59 have square grooves 512 inside. The two ends of the crossbeam 3 are respectively fixed with square locking blocks 510 that are inserted into the square grooves 512. By inserting the square locking blocks 510 into the corresponding square grooves 512, the crossbeam 3 can be installed on the side frame 2, which facilitates the installation and disassembly of the crossbeam 3. At the same time, the support blocks 59 have U-shaped grooves 513 inside. The front and rear sides of the square locking blocks 510 are respectively fixed with round locking blocks 511 that are engaged with the U-shaped grooves 513. By locking the round locking blocks 511 into the corresponding U-shaped grooves 513, the current installation position of the crossbeam can be made more stable.

[0041] like Figure 3 As shown, a limiting structure 6 is provided on the crossbeam 3. By providing the limiting structure, it is convenient to load and unload the roll material on the crossbeam while simultaneously limiting the circumferential and axial rotation of the roll material shaft, thereby achieving the positioning stability of the roll material at the top of the crossbeam. In this embodiment, the limiting structure 6 includes a limiting groove 61 opened at the top of the crossbeam 3. The limiting groove 61 cooperates with the rotation shaft of the roll material 4 to limit the circumferential rotation of the roll material shaft. At the same time, a limiting post 62 is fixedly connected to the top of the crossbeam 3 on one side of the roll material 4, and a limiting plate 63 is rotatably connected to the top of the crossbeam 3 on the other side of the roll material 4. The limiting plate 63 has a slot 64 that cooperates with the limiting post 62. By rotating the limiting plate 63 around its own hinge point, the slot 64 cooperates with the limiting post 62 to limit the rotation of the roll material shaft, thereby achieving axial limitation at both ends of the roll material shaft.

[0042] The specific working process of this embodiment is as follows:

[0043] Pull the side frame 2 upwards. At this time, the slide bar 52 slides upwards along the mounting column 51, so that the limiting block 54 compresses the elastic element 58 and moves away from the U-shaped plate 53. Then rotate the side frame 2 so that one side frame 2 is laid down and contacts the base frame 1. Repeat the above operation so that the other side frame 2 is laid down and located on top of the first side frame 2, thereby realizing the stacking of the two side frames after they are laid down. Thus, during transportation, the two side frames can be stacked after being laid down by the lifting and rotating movements of the two side frames relative to the bottom base frame, which is convenient for transportation and handling.

[0044] In use, push the side frame 2 downwards, compress the elastic element 58, and the U-shaped plate 53 will lock the limiting block 54, thereby limiting the side frame 2. Then push the round rod 55 to lock it into the corresponding round groove 56, which can limit the limiting block 54 and prevent it from sliding out of the U-shaped plate 53 by accident. The two round rods 55 can be moved simultaneously by pulling the connecting rod 57, making the operation more convenient. The elastic element 58 can always be located inside the round groove 56 in its natural state, which further improves the stability of limiting the limiting block 54.

[0045] When installing the crossbeam 3, insert the round locking block 511 into the corresponding square groove 512 to install the crossbeam 3 on the side frame 2, which facilitates the installation and disassembly of the crossbeam 3. Then, insert the round locking block 511 into the corresponding U-shaped groove 513 to make the crossbeam 3 more stable in the current installation position. Insert the rotating shaft of the roll body 4 into the two limiting grooves 61 to circumferentially limit the roll body 4. Rotate the limiting plate 63 so that the locking groove 64 is locked on the limiting post 62 to axially limit the roll body 4 at both ends, making the position of the roll body 4 more stable.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may use the disclosed technical content to make changes or modifications to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the scope of the utility model's technical solution, still fall within the protection scope of this utility model's technical solution. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through specific circumstances.
