Description

Technical Field

[0001] This utility model belongs to the field of material rack technology, specifically relating to a metal material rack that can achieve multi-layer adjustment. Background Technology

[0002] Metal shelving units are typically made of steel, aluminum alloys, or other metals, offering high strength, durability, and corrosion resistance. Their structural design can be customized to meet specific needs, such as using modular designs for easy assembly and disassembly, or employing welding, bolting, or other methods to enhance stability. Some shelving units are also equipped with adjustable shelves, casters, or rails to accommodate items of varying sizes and weights.

[0003] Metal material racks can be used in the industrial field to store mechanical parts, metal sheets, tools, etc., supporting mechanized handling and automated warehousing; when used in the logistics and warehousing field, they serve as heavy-duty racks to store large quantities of goods and improve space utilization.

[0004] In practical use, existing metal shelving typically uses bolted connections between shelves and uprights, meaning the shelves are directly bolted to the side surface of the uprights. This traditional design means that when users need to adjust shelf height according to storage requirements, they must individually remove the bolts, manually raise or lower the shelf to the target position, and then retighten the bolts to complete the fixation. Due to the large number of bolts and the need for precise alignment, the entire adjustment process is not only cumbersome but also consumes a significant amount of time and manpower. Especially in multi-layer shelving or heavy-duty shelf scenarios, frequent disassembly and assembly operations can easily lead to stripped bolts and worn upright holes, further increasing maintenance costs and safety hazards. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-layer adjustable metal material rack, which aims to solve the problem that in the existing metal material rack, the partitions are usually connected to the side surface of the upright by bolts. Therefore, when the height of the partitions of the metal material rack needs to be adjusted, the bolts need to be removed, the height of the partitions need to be adjusted, and then fixed with bolts. The adjustment process is complicated, time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal material rack capable of multi-layer adjustment, comprising,

[0007] The main body of the material rack includes a base plate with a bottom side, uprights connected to the four corner surfaces of the base plate, and a top plate connected to the top of the inner wall of the uprights;

[0008] The adjustment assembly includes a middle partition plate disposed between the bottom plate and the top plate and located inside the upright, a linkage part installed on the bottom side of the bottom plate and passing through the middle partition plate, and a fixing part connecting the middle partition plate and the linkage part.

[0009] As a preferred embodiment of the metal material frame capable of multi-layer adjustment according to this utility model, the linkage part includes a first bearing that penetrates and is connected to the side surface of the base plate, a connecting rod that penetrates and is connected inside the first bearing, a first knob connected to the end of the connecting rod, and a driving bevel gear connected to the surface of the connecting rod.

[0010] As a preferred embodiment of the present invention, a metal material frame capable of multi-layer adjustment, the linkage part further includes a second bearing that is installed through the surface of the base plate, a threaded rod that is connected through the inside of the second bearing and through the end of the middle partition plate, a driven bevel gear that is connected to the end of the threaded rod and meshes with the driving bevel gear, and an internal threaded tube that is sleeved on the surface of the threaded rod and matches its size.

[0011] As a preferred embodiment of the metal material frame capable of multi-layer adjustment according to this utility model, the driving bevel gear, driven bevel gear, threaded rod, and internal threaded tube are symmetrically arranged at both ends of the middle layer partition, and the threaded rod and internal threaded tube are threadedly connected.

[0012] As a preferred embodiment of the present invention, a metal material rack capable of multi-layer adjustment, the fixing part includes a third bearing sleeved on the top of the inner spiral tube and installed inside the middle partition, and a second knob connected to the bottom end of the inner spiral tube.

[0013] As a preferred embodiment of the metal material frame capable of multi-layer adjustment according to this utility model, the fixing part further includes a fixing screw tube that passes through and is connected to the side surface of the inner screw tube, a fixing hole that is opened on the side surface of the middle partition plate, a fixing bolt that passes through the inside of the fixing hole and matches the inner screw tube, and a third knob connected to the end of the fixing bolt.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention allows for simultaneous height adjustment of two middle partitions by using a first knob, a connecting rod, a driving bevel gear, a driven bevel gear, a threaded rod, and an internal threaded tube. This improves the efficiency of middle partition height adjustment and reduces manual labor.

[0016] In this invention, when the third knob drives the fixing bolt to rotate inside the fixing screw tube, it can move laterally. When the fixing bolt moves to the outside of the fixing screw tube, the second knob is rotated to drive the inner screw tube to rotate on the threaded rod. At the same time, the inner screw tube rotates and moves longitudinally, which in turn drives the middle partition to move longitudinally. This allows the height of the middle partition to be adjusted individually, so that the height of a single middle partition can be adjusted according to actual needs. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-6 This utility model provides the following technical solution: a metal material rack capable of multi-layer adjustment, comprising,

[0027] The main body 100 of the material rack includes a base plate 101 with a bottom side, uprights 102 connected to the four corner surfaces of the base plate 101, and a top plate 103 connected to the top of the inner wall of the uprights 102.

[0028] The adjustment assembly 200 includes a middle partition 201 disposed between the base plate 101 and the top plate 103 and located inside the upright 102, a linkage part 202 installed on the bottom side of the base plate 101 and passing through the middle partition 201, and a fixing part 203 connecting the middle partition 201 and the linkage part 202.

[0029] Preferably, the linkage 202 includes a first bearing 202a that is connected through to the side surface of the base plate 101, a linkage rod 202b that is connected through to the inside of the first bearing 202a, a first knob 202c that is connected to the end of the linkage rod 202b, and a drive bevel gear 202d that is connected to the surface of the linkage rod 202b.

[0030] In practical use, when the first knob 202c is rotated, it can drive the connecting rod 202b to rotate inside the first bearing 202a. When the connecting rod 202b rotates, it can drive the driving bevel gear 202d to rotate. When the driving bevel gear 202d rotates, it can drive the driven bevel gear 202g to rotate through the meshing structure. When the driven bevel gear 202g rotates, it can drive the threaded rod 202f to rotate inside the second bearing 202e. In this way, the transmission between the connecting rod 202b and the threaded rod 202f can be realized.

[0031] Preferably, the linkage 202 further includes a second bearing 202e that is installed through the surface of the base plate 101, a threaded rod 202f that is connected through the inside of the second bearing 202e and passes through the end of the middle partition 201, a driven bevel gear 202g that is connected to the end of the threaded rod 202f and meshes with the driving bevel gear 202d, and an internal threaded tube 202h that is sleeved on the surface of the threaded rod 202f and matches its size.

[0032] In practical use, when the threaded rod 202f rotates, it can drive the inner threaded tube 202h to move longitudinally through the threaded connection structure. The longitudinal movement of the inner threaded tube 202h can drive the middle partition 201 to move longitudinally, so that the height of the two middle partitions 201 can be adjusted at the same time.

[0033] Preferably, the driving bevel gear 202d, the driven bevel gear 202g, the threaded rod 202f and the internal threaded tube 202h are symmetrically arranged at both ends of the middle partition 201, and the threaded rod 202f and the internal threaded tube 202h are threadedly connected.

[0034] In practical use, the smoothness of the adjustment of the middle partition 201 can be ensured by using two sets of driving bevel gears 202d, driven bevel gears 202g, threaded rods 202f and internal threaded tubes 202h respectively set at both ends of the middle partition 201.

[0035] Preferably, the fixing part 203 includes a third bearing 203a sleeved on the top of the inner threaded tube 202h and installed inside the middle partition 201, and a second knob 203b connected to the bottom end of the inner threaded tube 202h.

[0036] Preferably, the fixing part 203 further includes a fixing tube 203c that is connected through to the side surface of the inner tube 202h, a fixing hole 203d that is opened on the side surface of the middle partition 201, a fixing bolt 203e that is connected through the inside of the fixing hole 203d and matches the inner tube 202h, and a third knob 203f connected to the end of the fixing bolt 203e.

[0037] In practical use, turning the third knob 203f can drive the fixing bolt 203e to rotate inside the inner threaded tube 202h. While the fixing bolt 203e is rotating inside the inner threaded tube 202h, it can move laterally through the threaded connection. When the fixing bolt 203e moves to the outside of the inner threaded tube 202h, the fixed connection between the inner threaded tube 202h and the middle partition 201 is released.

[0038] Working principle: When the height of the two middle partitions 201 of the metal material rack needs to be adjusted, the first knob 202c can be turned. When the first knob 202c is turned, it can drive the connecting rod 202b to rotate. When the connecting rod 202b is turned, it can drive the driving bevel gear 202d to rotate. When the driving bevel gear 202d is turned, it can drive the driven bevel gear 202g to rotate. When the driven bevel gear 202g is turned, it can drive the threaded rod 202f to rotate. When the threaded rod 202f is turned, it can drive the internal thread tube 202h to move longitudinally. The longitudinal movement of the internal thread tube 202h can simultaneously drive the two middle partitions 201 to move longitudinally, thereby adjusting the height of the two middle partitions 201.

[0039] When the third knob 203f is turned, the fixing bolt 203e can rotate inside the fixing screw tube 203c. When the fixing bolt 203e rotates in the horizontal part of the fixing screw tube 203c, it can move laterally. When the fixing bolt 203e moves to the outside of the fixing screw tube 203c, the second knob 203b can be turned. When the second knob 203b is turned, the inner screw tube 202h can rotate. When the inner screw tube 202h rotates on the surface of the threaded rod 202f, it can move longitudinally. In this way, by simultaneously turning the second knobs 203b at both ends of the same middle partition 201, the middle partition 201 can be moved longitudinally, and the height of the middle partition 201 can be adjusted individually.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
