Description

Technical Field

[0001] This utility model relates to the field of stackable rack technology, specifically to a stackable rack with a closed bottom. Background Technology

[0002] Stacking racks, also known as pallet racks or stacking shelves, are handling and storage equipment derived from pallets. They are multi-functional devices for unitizing goods, storing and distributing merchandise, and require the use of forklifts. The existing technology has the following problems: Existing stacking racks are usually fixed in size, making it inconvenient to adjust their height and reducing their flexibility. Secondly, stacking racks typically use angle iron as the stacking contact part, resulting in poor overall stability of the rack connection. This makes it easy for the rack to tip over during multi-level transportation, leading to product damage. Utility Model Content

[0003] This utility model provides a bottom-closed stacking bracket to solve the problems existing in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The bottom-closed stacking frame includes a closed base plate. Lifting components are respectively provided at the top of the closed base plate near the four corners. Foot plates are respectively fixedly connected to the left and right sides of the bottom of the closed base plate. Top plates are respectively fixedly connected to the top of the two left and right lifting components. Positioning components are respectively provided on the outside of the two top plates. Three guard plates are fixedly connected to the top of the closed base plate. The outside of the three guard plates are respectively located on the opposite side of the two lifting components.

[0005] A further improvement of this utility model is that: a triangular slot is provided on the adjacent side of the bottom of the two foot plates, and a triangular bracket is fixedly connected to the top of the two top plates.

[0006] A further improvement of this utility model is that the top plate engages with the inside of the triangular slot through the outer wall of the triangular bracket, and the positioning component is externally disposed on the outside of the foot plate.

[0007] A further improvement of this utility model is that the exteriors of the two lifting components are mirror images of each other. Each lifting component includes a hollow square tube, a support plate, a screw, and a knob. The exterior of the support plate is sleeved with the interior of the hollow square tube. A plurality of fixing holes are equidistantly arranged at one end of the hollow square tube. A threaded hole is provided at the bottom of one end of the support plate. One end of the screw is fixedly connected to the middle of the knob. The outer wall of the screw is threadedly connected to the interior of the threaded hole through the fixing hole.

[0008] A further improvement of this utility model is that the bottom of the hollow square tube is fixedly connected to the upper surface of the closed base plate, and the top of the support plate is fixedly connected to the lower surface of the top plate.

[0009] A further improvement of this utility model is that several insertion holes are equidistantly arranged on the bottom of the two foot plates near the triangular slot.

[0010] A further improvement of the present invention is that the positioning component includes several extension plates, several upright plates and several insert rods. One end of the several extension plates is equidistantly arrayed at one end of the top plate. The bottom of the upright plate is fixedly connected to the top of the extension plate on the side away from the triangular bracket. The bottom of the insert rod is fixedly connected to the upper surface of the top plate on the outer side near the triangular bracket.

[0011] A further improvement of this utility model is that: the inner wall of the upright plate overlaps with the inner surface of the footboard, the number of the insert rods is equal to the number of the insertion holes, and the outer wall of the insert rod is inserted into the interior of the insertion hole.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This utility model provides a bottom-closed stacking rack, which uses a combination of a closed base plate, a lifting assembly, and a protective plate. By extending and retracting the support plate in the lifting assembly on the closed base plate along the interior of a hollow square tube to adjust the length between the lifting assemblies, and using screws to position and fix the hollow square tube and the support plate, the height of the stacking rack can be adjusted. This solves the problem that existing stacking racks are usually fixed in size, making it inconvenient to adjust the height of the stacking rack and reducing the flexibility of the stacking rack in use. It achieves the beneficial effect of facilitating the height adjustment of the stacking rack and improving the flexibility of the stacking rack in use.

[0013] This utility model provides a bottom-closed stackable rack, which uses the cooperation between the foot plate, the top plate and the positioning component. When multiple stackable racks are stacked, the foot plate on the upper stack is locked onto the triangular mounting piece by the triangular slot, and the positioning component restricts the outside of the foot plate, thereby preventing the upper stackable rack from slipping. This solves the problem that stackable racks usually use angle iron as the stacking contact part, resulting in poor overall stability of the rack connection, which easily causes the stackable rack to tip over during multi-level transportation, leading to product damage. It achieves the beneficial effect of preventing multiple stackable racks from tipping over when stacked and improving the stability of the stackable rack. Attached Figure Description

Detailed Implementation

[0016] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments: like Figure 1 As shown, this utility model provides a bottom-closed stacking frame, including a closed base plate 1, lifting components 2 are respectively provided on the top of the closed base plate 1 near the four corners, foot plates 3 are respectively fixedly connected to the left and right sides of the bottom of the closed base plate 1, top plates 4 are respectively fixedly connected to the top of the left and right lifting components 2, positioning components 5 are respectively provided on the outside of the two top plates 4, and three guard plates 6 are fixedly connected to the top of the closed base plate 1, with the outside of the three guard plates 6 respectively provided on the opposite sides of the two lifting components 2. The system consists of a closed base plate 1, a lifting assembly 2, a footboard 3, a top plate 4, a positioning assembly 5, and a guard plate 6. The height of the stacking rack can be adjusted by installing the lifting assembly 2 on the closed base plate 1. Meanwhile, the positioning assembly 5 on the top plate 4 improves the stability of stacking multiple stacking racks.

[0017] like Figure 2 As shown, this utility model provides a bottom-closed stackable rack technical solution: two foot plates 3 each have a front-to-back through triangular slot 301 on one side of their bottom, and two top plates 4 each have a triangular bracket 41 fixedly connected to their tops. The top plates 4 engage with the inside of the triangular slot 301 through the outer wall of the triangular bracket 41. The positioning component 5 is set outside the foot plates 3. The upper foot plate 3 engages with the lower triangular bracket 41 through the triangular slot 301, thus achieving the effect of stacking multiple stackable racks.

[0018] like Figure 3As shown, this utility model provides a bottom-closed modular frame technical solution: the exteriors of the front and rear lifting components 2 are mirror images of each other. Each lifting component 2 includes a hollow square tube 21, a support plate 22, a screw 23, and a knob 24. The exterior of the support plate 22 is sleeved with the interior of the hollow square tube 21. One end of the hollow square tube 21 has several fixing holes 210 arranged in an equidistant array. One end of the support plate 22 has a threaded hole 220 at its bottom. One end of the screw 23 is fixedly connected to the middle of the knob 24. The outer wall of the screw 23 is open... The bottom of the hollow square tube 21 is fixedly connected to the upper surface of the closed base plate 1 through the internal threaded connection between the fixing hole 210 and the threaded hole 220. The top of the support plate 22 is fixedly connected to the lower surface of the top plate 4. By extending and retracting the support plate 22 along the inside of the hollow square tube 21, the threaded hole 220 on the support plate 22 is aligned with the fixing hole 210 at the corresponding height. Then, the screw 23 is screwed into the threaded hole 220 through the fixing hole 210, thereby completing the adjustment and fixing of the length of the lifting component 2.

[0019] like Figure 4-5 As shown, this utility model provides a bottom-closed modular support structure: Two footplates 3 have several equidistantly arranged insertion holes 302 on one side of their bottoms near the triangular slot 301. The positioning assembly 5 includes several extension plates 51, several upright plates 52, and several insertion rods 53. One end of each extension plate 51 is equidistantly arranged at one end of the top plate 4. The bottom of each upright plate 52 is fixedly connected to the top of the extension plates 51 on the side away from the triangular footplate 41. The bottom of each insertion rod 53 is fixedly connected to the top surface of the top plate 4. The inner wall of the upright plate 52 overlaps with the inner surface of the foot plate 3 on the outer side of the triangular bracket 41. The number of insert rods 53 is equal to the number of insertion holes 302. The outer wall of the insert rod 53 is inserted into the inside of the insertion hole 302. When the lower foot plate 3 is mounted on the upper top plate 4, the insert rod 53 is inserted into the insertion hole 302, and the upright plate 52 is locked on the inner surface of the foot plate 3 to position the foot plate 3, thereby improving the stability of the stacked racks and preventing the racks from tipping over when stacked.

[0020] The working principle of this bottom-closed stacking frame will be explained in detail below.

[0021] like Figure 1-5As shown, when using the bottom-closed stackable rack, the support plate 22 can be moved telescopically along the interior of the hollow square tube 21 in sequence, so that the threaded hole 220 on the support plate 22 is aligned with the corresponding fixing hole 210 on the hollow square tube 21. Then, the screw 23 is inserted along the fixing hole 210, and the knob 24 is turned to screw the screw 23 into the threaded hole 220, thereby fixing the support plate 22 inside the hollow square tube 21, which facilitates the adjustment of the height of the stackable rack. When stacking multiple stackable racks, the foot plate 3 at the bottom of the upper closed base plate 1 is engaged with the outside of the lower triangular bracket 41 through the triangular slot 301. At the same time, multiple inserts 53 on the top plate 4 are inserted into the insertion holes 302, so that the upright plate 52 is locked on the inner surface of the foot plate 3 for limiting, increasing the stability of the stacking of the upper and lower stackable racks and preventing multiple stackable racks from tipping over and slipping when stacked.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
