Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a space-adjustable warehouse shelving. Background Technology

[0002] Storage racks are an important tool for warehouse modernization and efficiency improvement, and their market demand is increasing. However, existing storage racks have fixed sizes and cannot accommodate storage spaces of different sizes.

[0003] Chinese patent CN221050625U discloses a space-adjustable storage rack. When the width of the partition needs to be adjusted, the large and small partitions are slid open as needed to increase the total width of the partition assembly. Then, the large and small partitions are locked with hand-tightened bolts, thereby increasing the width of the storage rack. During installation, the partition assembly is slidably installed from the top of the upright assembly. The spacing between multiple partition assemblies is set according to the size of the goods. When the partition assembly is at an appropriate height, the upright assembly and the partition assembly are locked by inserting hand-tightened bolts into the limiting holes and fixing holes.

[0004] However, the device still has shortcomings: when there are items on the partition, the items need to be removed before the height of the partition can be adjusted. Furthermore, when adjusting the height of the partition, the bolts need to be manually tightened to release its sliding limit before sliding the partition, and finally the height limit needs to be locked again, which is very troublesome to operate.

[0026] Example 1

[0027] like Figures 1-5As shown, this utility model proposes a space-adjustable storage rack, including a support frame 1, a drive assembly A4, pallets 5, a center plate 6, a drive assembly B, and a bracket. The bottom of the support frame 1 is equipped with casters with braking function. A guide rail 2 is provided on the support frame 1 along its height direction, and a rack A3 is provided on the guide rail 2. The drive assembly A4 includes, but is not limited to, a scissor-type telescopic fork, with both ends of the scissor-type telescopic fork connected to the corresponding side of the support frame 1. An electric telescopic rod is provided on the support frame 1 to drive the scissor-type telescopic fork to retract or extend, so as to adjust the distance between the two support frames 1 through the drive assembly A4. There are multiple pallets 5, each of which is set on the corresponding side of the support frame 1 and slides along its height direction. The center plate 6 is located between two support frames 1. Two pallets 5 at the same height on the two support frames 1 are inserted into the center plate 6 from both ends and slidably connected to it. Two storage slots 601 are symmetrically arranged on the center plate 6. The near ends of the two pallets 5 are inserted into the corresponding storage slots 601 and slidably connected to them. A splined bushing 9 is rotatably mounted on the center plate 6, and a splined shaft 13 is rotatably mounted on the support plate 5. The splined shaft 13 is inserted into the splined bushing 9 and slides along its axial direction. A gear B14 is coaxially mounted on the splined shaft 13, and the gear B14 meshes with the rack A3 on the corresponding side. A gear A8 is rotatably connected to the center plate 6 in the center. Two racks B7 are slidably connected to the center plate 6 at intervals. Both racks B7 mesh with the gear A8, and both racks B7 are connected to the support plate 5 on the corresponding side. Drive assembly B is mounted on center plate 6 and drives splined bushing 9 to rotate. Drive assembly B includes worm gear 10 and worm 11. Worm gear 10 is coaxially connected to splined bushing 9. Worm 11 is rotatably connected to center plate 6 and meshes with worm gear 10. A crank 12 is provided at one end of worm 11 extending out of center plate 6 so as to drive pallet 5 to rise or fall by the rolling of gear B14 along rack A3. Support is mounted at the bottom of pallet 5 and slidably connected to support frame 1. Support includes vertical plate 15 and diagonal brace 16. Vertical plate 15 is connected to the bottom of pallet 5 and slidably connected to support frame 1 on the corresponding side. One end of diagonal brace 16 is connected to the lower end of vertical plate 15 and the other end is connected to the end of pallet 5 away from support frame 1. Diagonal brace 16 is slidably connected to center plate 6. Locking assembly is provided on support. Locking assembly restricts the sliding of support and pallet 5 on support frame 1 in working state.The locking assembly includes a guide sleeve 17, a wedge-shaped locking block 19, and a drive assembly C. The guide sleeve 17 is mounted on the vertical plate 15, and a slider 18 is slidably connected to it. A guide rod is mounted on the guide sleeve 17, and a spring is fitted on the guide rod. The two ends of the spring abut against the guide sleeve 17 and the slider 18, respectively. One end of the wedge-shaped locking block 19 is inserted into the guide sleeve 17 and connected to the slider 18. Several slots 101 are equidistantly arranged on the support frame 1 along its height direction. The end of the wedge-shaped locking block 19 away from the slider 18 is inserted into the corresponding slot 101 and slidably connected to its inner wall. The bottom surface of the wedge-shaped locking block 19 is flat. The drive assembly C includes a permanent magnet 20 and an electromagnet 21. The permanent magnet 20 is connected to the slider 18, and the electromagnet 21 is connected to the guide sleeve 17. The electromagnet 21 and the permanent magnet 20 are directly opposite each other, so that the slider 18 can be controlled to slide back by energizing the electromagnet 21.

[0028] In this embodiment, when it is necessary to increase the distance between the two support frames 1, the electric telescopic rod is activated, which drives the scissor telescopic fork to extend, thereby gradually increasing the distance between the two support frames 1. During this process, the support plates 5 on both sides of the support frame 1 move away from each other. Due to the transmission action of the rack B7 and gear A8 inside the center plate 6, the center plate 6 is always in the central position of the device, and the spline shaft 13 always remains adapted to the spline bushing 9. Moreover, the stability of the support plate 5 and the center plate 6 can always be maintained at a very high level through the support of the vertical plate 15 and the diagonal brace 16, and the load-bearing capacity is strong. When the height of the pallet 5 needs to be adjusted, the electromagnet 21 is first energized. After the electromagnet 21 is energized, the magnetic poles of the permanent magnet 20 and the end of the electromagnet 21 that are close to each other are opposite, so that the electromagnet 21 attracts the permanent magnet 20. The permanent magnet 20 drives the slider 18 and the wedge-shaped block 19 to slide back and disengage from the slot 101, thereby realizing the sliding unlocking of the pallet. At this time, the pallet 5 is still under the action of the gear B14, the rack A3 and the worm gear and will not slide down automatically. The operator rotates the crank 12 on the corresponding layer center plate 6 to drive the worm 11 to rotate. The worm 11 drives the worm wheel 10 to rotate, which in turn drives the spline bushing 9 to rotate, which in turn drives the spline shaft 13 and the gear B14 to rotate. The gear B14 drives the pallet 5 to roll along the height direction of the rack A3, thereby changing the current height of the pallet. After the height is adjusted, the electromagnet 21 is de-energized, and the crank 12 is rotated again so that the wedge-shaped block 19 automatically engages in the nearest slot 101 under the action of spring tension.

[0029] Example 2

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the present invention proposes a space-adjustable storage rack. Compared with the first embodiment, the central plate 6 is provided with several upward-facing sliding grooves 602 that communicate with the storage slots 601. The pallet 5 is provided with several support bars 501 evenly spaced. Each support bar 501 is inserted into the corresponding side of the sliding groove 602 and slidably connected to its inner wall. The upper end face of the support bar 501 is flush with the upper end face of the central plate 6.

[0031] In this embodiment, the cooperation structure of the support bar 501 and the slide 602 is used to make the load-bearing surface of the pallet 5 and the load-bearing surface of the center plate 6 at the same height, so as to avoid unevenness on the same layer of support structure.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
