Description

Technical Field

[0001] This utility model relates to the field of shelving installation technology, and more specifically, to a layered adjustable mezzanine shelving device. Background Technology

[0002] Mezzanine racking is a warehousing solution that achieves efficient vertical space utilization by building multi-level steel structure platforms above existing warehouses or shelves. Its core advantage lies in doubling space utilization (typically by 50%-100%), while also ensuring flexibility and safety, making it suitable for various fields such as warehousing, manufacturing, and e-commerce.

[0003] The purpose of installing mezzanine racking is to improve the space utilization of existing racking. However, the basic principle of current mezzanine racking installation is to add the same structure to the existing racking. This type of mezzanine racking is not convenient for adjusting the layer spacing. Furthermore, because it is located at a high position, adjustments require removing the items on that layer, disassembling the four corner fixing structures, and then adjusting, resulting in reduced safety and efficiency. Therefore, we propose a layer-adjustable mezzanine racking device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a layered adjustable mezzanine racking device to solve the technical problem that current mezzanine racking is not easy to adjust.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a layered adjustable mezzanine shelving device, including a support frame and a positioning adjustment structure located on the support frame. The positioning adjustment structure includes an adjustment plate, the front end of which is provided with a partition for placing shelves, and the bottom of which is provided with a torsion spring. The torsion spring is connected to a downward limiting plate based on the adjustment plate. The downward limiting plate cooperates with the support frame. The adjustment plate is provided with a front adjustment rod that penetrates through the adjustment plate. The front adjustment rod is provided with a positioning roller. Connecting belts are connected to both sides of the positioning roller. An arc-shaped guide plate is provided at the end of the connecting belt away from the positioning roller. The arc-shaped guide plate is connected to a torsion spring located inside the adjustment plate.

[0006] Preferably, the bracket is provided with an adjustment groove for adjusting the plate to move up and down and to be fixed. The side wall of the adjustment groove is a groove structure that cooperates with the sliding limit plate laterally. The front end of the adjustment groove is in a protruding position when it contacts the adjustment plate.

[0007] Preferably, under normal pressure, the second torsion spring is in contact with the adjusting plate on one side of the downward limiting plate it is connected to, and the first torsion spring is in contact with the downward limiting plate through the adjusting plate under normal pressure. When both the first and second torsion springs are under normal pressure, the torque of the first torsion spring is greater than that of the second torsion spring.

[0008] Preferably, the adjusting plate is further provided with a fixed pulley for adjusting the tension direction of the connecting belt. When the side of the connecting belt connected to the positioning roller moves upward, it drives the arc-shaped guide plate to make a circular motion based on the torsion spring.

[0009] Preferably, the front end of the adjusting plate is provided with a front adjusting groove for the front adjusting rod to pass through, a shaft is provided between the front adjusting rod and the front adjusting groove, a connecting rod is provided at the bottom of the positioning roller, a groove is provided between the front adjusting rod and the positioning roller, and a shaft that cooperates with the connecting rod is provided in the groove.

[0010] Preferably, the end of the front adjusting rod away from the adjusting plate is provided with a rear connecting rod, and a double-sided adjusting box is provided on the partition at the middle connection point of the two rear connecting rods, and the rear connecting rod moves up and down based on the double-sided adjusting box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a positioning and adjustment structure, uses a torsion spring connected to the adjustment plate to drive the angle movement of the lower limit plate, enabling it to move upward in conjunction with the structure on the bracket. This allows the shelf to slide freely on one side without disassembly, improving the upward adjustment performance. Manually, one only needs to prop up the partition, observe the position of the lower limit plate, and then lower the partition; no additional screw disassembly is required. Furthermore, for arbitrary fixing, adjusting the front adjustment rod drives the positioning roller, which in turn pulls up the connecting belt, thereby driving the arc-shaped guide... The guide plate rotates based on the torsion spring, causing the bottom of the arc-shaped guide plate to separate from the lower limit plate, thus enabling the lower limit plate to slide down and be fixed. In general, when sliding is needed, there is no need to adjust the arc-shaped guide plate, which is used to press against the lower limit plate, ensuring that the lower limit plate does not act on the support structure. If fixing is needed, the connecting strap is pulled up to fix the lower limit plate to the support structure, and then the connecting strap is lowered to drive the arc-shaped guide plate back to its original position. This method enables direct one-sided operation and adjustment, improves the efficiency of layered adjustment, and eliminates the need for disassembly, solving the technical problem of the current mezzanine racks being inconvenient to adjust.

[0012] 2. This utility model also designs the cooperation between the arc-shaped guide plate and the connecting belt. That is, the up and down movement of the positioning roller is adjusted by the up and down movement of the front adjusting rod, thereby realizing the tension adjustment of the connecting belt, driving the arc-shaped guide plate to rotate, thereby realizing the pressure adjustment of the sliding limit plate that contacts the bottom of the arc-shaped guide plate, realizing the purpose of actively controlling the angle of the sliding limit plate, and finally realizing the control of the connection between the sliding limit plate and the bracket, realizing the limit control of the overall up and down movement of the positioning adjustment structure, improving the bilateral control performance, eliminating the need for individual corner control, and improving the movement efficiency.

Detailed Implementation

[0015] like Figures 1 to 6As shown, this utility model relates to a layered adjustable mezzanine shelving device, which includes the following technical solution: A layered adjustable mezzanine shelving device includes a support 100 and a positioning adjustment structure 200 located on the support 100. The positioning adjustment structure 200 includes an adjustment plate 210. The front end of the adjustment plate 210 is provided with a partition 220 for placing shelves. The bottom of the adjustment plate 210 is provided with a torsion spring 260. The torsion spring 260 is connected to a downward limiting plate 250 based on the adjustment plate 210. The downward limiting plate 250 cooperates with the support 100. The adjustment plate 210 is provided with a front adjustment rod 240 that penetrates the adjustment plate 210. The front adjustment rod 240 is provided with a positioning roller 234. The positioning roller 234 is connected to two sides with connecting straps 233. The end of the connecting strap 233 away from the positioning roller 234 is provided with an arc-shaped guide plate 230. The arc-shaped guide plate 230 is connected to a torsion spring 231 located inside the adjustment plate 210.

[0016] This utility model designs a positioning and adjustment structure 200, which uses a torsion spring 260 connected to the adjustment plate 210 to drive the downward limiting plate 250 to move at an angle. This allows the plate to move upward in conjunction with the structure on the bracket 100, enabling the shelf to slide freely on one side without disassembly. This improves the upward adjustment performance. The operator only needs to prop up the partition 220, observe the position of the downward limiting plate 250, and then lower the partition 220; no additional screw disassembly is required. Furthermore, when arbitrary fixing is needed, adjusting the front adjustment rod 240 drives the positioning roller 234, which in turn pulls up the connecting belt 233, thereby driving the arc-shaped guide plate 230 to its base. The rotation of torsion spring 231 causes the bottom of the arc-shaped guide plate 230 to separate from the lower limit plate 250, thus enabling the lower limit plate 250 to slide down and be fixed. In general, if sliding is required, there is no need to adjust the arc-shaped guide plate 230 to press against the lower limit plate 250, ensuring that the lower limit plate 250 does not act on the upper structure of the bracket 100. If fixing is required, the connecting strap 233 is pulled up to fix the lower limit plate 250 to the upper structure of the bracket 100, and then the connecting strap 233 is lowered to drive the arc-shaped guide plate 230 back to its original position. This method enables direct operation and adjustment on one side, improves the efficiency of layered adjustment, eliminates the need for disassembly, and solves the technical problem of the current mezzanine racks being inconvenient to adjust.

[0017] This utility model also designs the cooperation between the arc-shaped guide plate 230 and the connecting belt 233, that is, based on the up and down movement of the front adjusting rod 240, the up and down movement of the positioning roller 234 is adjusted, thereby realizing the tension adjustment of the connecting belt 233, driving the arc-shaped guide plate 230 to rotate, thereby realizing the pressure adjustment of the sliding limit plate 250 that is in contact with the bottom of the arc-shaped guide plate 230, realizing the purpose of actively controlling the angle of the sliding limit plate 250, and finally realizing the control of the connection between the sliding limit plate 250 and the bracket 100, realizing the limit control of the overall up and down movement of the positioning adjustment structure 200, improving the bilateral control performance, eliminating the need for individual corner control, and improving the movement efficiency.

[0018] Specifically, the bracket 100 is provided with an adjustment groove 110 for adjusting the plate 210 to move up and down and to fix it. The side wall of the adjustment groove 110 is a groove structure that cooperates with the sliding limit plate 250 laterally. The front end of the adjustment groove 110 is in the contact position with the adjustment plate 210. The adjustment groove 110 is composed of a vertical groove in the middle and a horizontal groove symmetrically located on the side of the vertical groove. When the sliding limit plate 250 is in the horizontal state, it contacts the horizontal groove and fixes the entire adjustment plate 210. The vertical groove guides the adjustment plate 210 to slide up and down. At the same time, the protruding structure on the vertical groove protects the adjustment plate 210 from movement and improves stability.

[0019] Furthermore, under normal pressure, one side of the sliding limit plate 250 connected to the second torsion spring 260 is in contact with the adjusting plate 210. Under normal pressure, the arc-shaped guide plate 230 connected to the first torsion spring 231 penetrates the adjusting plate 210 and contacts the sliding limit plate 250. When both the first torsion spring 231 and the second torsion spring 260 are under normal pressure, the torque of the first torsion spring 231 is greater than that of the second torsion spring 260. When the second torsion spring 260 is under normal pressure, it ensures that the first torsion spring 231 is compressed, thereby driving the arc-shaped guide plate. 230 retracts, at which point the downward limiting plate 250 contacts the adjusting plate 210, which can cooperate with the adjusting groove 110 to fix the adjusting plate 210 as a whole. If the torsion spring 231 is under constant pressure, 260 is under constant pressure. Due to the large torque of the torsion spring 231, it will squeeze the downward limiting plate 250, making it unable to contact the adjusting groove 110, and thus unable to fix the adjusting plate 210. This method is suitable for the downward state, that is, adjusting the position of the arc guide plate 230 can achieve the purpose of moving the adjusting plate 210 as a whole.

[0020] It is worth noting that the interior of the adjusting plate 210 is also provided with a fixed pulley 232 for adjusting the tension direction of the connecting belt 233. When the side of the connecting belt 233 connected to the positioning roller 234 moves upward, it drives the arc-shaped guide plate 230 to make a circular motion based on the torsion spring 231. The fixed pulley 232 realizes the adjustment of the tension direction, increases the utilization rate of the internal space of the adjusting plate 210, and facilitates the control of the two arc-shaped guide plates 230 of a single adjusting plate 210, so as to achieve the purpose of controlling a single front-end adjusting rod 240 and improve controllability.

[0021] It is worth mentioning that the front end of the adjusting plate 210 is provided with a front adjusting groove 211 for the front adjusting rod 240 to pass through. A shaft is provided between the front adjusting rod 240 and the front adjusting groove 211. A connecting rod is provided at the bottom of the positioning roller 234. A groove is provided between the front adjusting rod 240 and the positioning roller 234, and a shaft that cooperates with the connecting rod is provided in the groove. The front adjusting rod 240 rotates through the front adjusting groove 211 based on the shaft, thereby driving the connecting rod connected to it to move up and down, so as to drive the connecting belt 233 to move, thereby realizing the angle adjustment of the arc-shaped guide plate 230 and facilitating control.

[0022] It is worth noting that the end of the front adjusting rod 240 away from the adjusting plate 210 is provided with a rear connecting rod 241. A double-sided adjusting box 242 located on the partition plate 220 is provided at the midpoint of the connection between the two rear connecting rods 241. The rear connecting rods 241 move up and down based on the double-sided adjusting box 242; the rear connecting rods 241 extend out and are located inside the double-sided adjusting box 242. A lever is provided inside the double-sided adjusting box 242 to control the two rear connecting rods 241, which can drive the rear connecting rods 241 to move up and down, thereby driving the front adjusting rod 240 to move up and down, achieving linkage control.

[0023] Working Principle: This embodiment provides a layered adjustable mezzanine shelving device. In use, the shelves are placed on the left and right partitions 220. When height adjustment is required, and downward movement is needed, the user lifts one side partition 220. The two positioning adjustment structures 200 on that side move, and the bottom of the sliding limit plate 250 separates from the adjustment groove 110. It is then pressed inward by the arc-shaped guide plate 230, preventing it from contacting the transverse groove of the adjustment groove 110. Then, it can be moved up and down. After reaching the designated position, the rear connecting rod 241 inside the double-sided adjustment box 242 is manually adjusted to connect... When the front adjustment rod 240 is pressed down, the end connected to the positioning roller 234 inside the adjustment plate 210 rises after passing through the adjustment plate 210, which drives the connecting belt 233 to pull up, thereby driving the arc guide plate 230 to rotate into the adjustment plate 210. At this time, the arc guide plate 230 separates from the lower limit plate 250. After the lower limit plate 250 contacts the adjustment groove 110, it presses down and contacts the vertical groove on the adjustment groove 110 to fix the adjustment plate 210. Then, the rear connecting rod 241 is manually released to fall into the double-sided adjustment box 242. The other side positioning adjustment structure 200 is adjusted in the same way to achieve the purpose of layered adjustment.

[0024] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
