Description

Technical Field

[0001] This invention relates to a support, specifically a multi-layer stacked storage tray support. Background Technology

[0002] Prefabricated buildings refer to the transfer of a large amount of on-site work in traditional construction methods to factories. Components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Most of the transportation uses direct stacking, and for ease of stacking, wider pallets are placed on the lower layer and smaller pallets on the upper layer. Palletized prefabricated transportation is the most common.

[0003] However, if direct stacking or the use of a double-layer support structure is adopted for transportation, the support structure, which is mostly a one-piece molded structure welded together, will occupy a large space after use, making the transportation and storage of the support itself troublesome. Although double-layer supports are convenient for transportation, the space utilization is still limited.

[0004] Therefore, the known direct stacking or double-layer support structures have the aforementioned inconveniences and problems. Summary of the Invention

[0005] The purpose of this invention is to provide a safe and reliable multi-layer stackable storage tray support.

[0006] To achieve the above objectives, the technical solution of the present invention is:

[0007] A multi-layer stackable storage tray support, comprising two base plates, characterized in that:

[0008] Two first horizontal bars are added between the two base plates. Each end of the two base plates is clamped with a first column. One first horizontal bar is clamped with each of the two first columns. Each first column is fixedly connected to one side with a first side support block. A second horizontal bar is connected between the two first side support blocks. A total of two second horizontal bars are provided. A connecting shaft is provided between the two ends of the two second horizontal bars. A total of two connecting shafts are provided. The two second horizontal bars are connected together through the connecting shafts. The first horizontal bars and the second horizontal bars are parallel to each other. The second horizontal bars and the first horizontal bars are perpendicular to each other.

[0009] The base plate has a locking block for engaging the first column. The lower end of the first column has a locking block that engages with the mounting opening. The base plate 1 and the first crossbar are connected together by a first arc-shaped locking shaft and a second arc-shaped locking shaft. The first arc-shaped locking shaft and the second arc-shaped locking shaft are positioned above the locking block and are engaged with each other. The first crossbar has a groove. The two ends of the first arc-shaped locking shaft pass through the groove and engage with both sides of the first column. The outer sides of both ends of the first arc-shaped locking shaft have first slots. The two ends of the second arc-shaped locking shaft engage with the two first slots respectively. The first arc-shaped locking shaft and the second arc-shaped locking shaft form a ring to connect the first crossbar and the first column.

[0010] A connecting shaft is connected between the two ends of the two second horizontal bars. Two pins are fixedly installed at both ends of the connecting shaft. The two pins are inserted and locked into the end of the connecting shaft. A second column is inserted into the end of the two connecting shafts. A U-shaped retaining shaft is installed at the connection between the second column and the connecting shaft. One end of the U-shaped retaining shaft passes through both the first column and the second column and is located above the connecting shaft. The lower end of the U-shaped retaining shaft abuts against the lower end of the second column.

[0011] Each second column has a second side support block fixedly installed on its upper side. A third crossbar connects the two second side support blocks. The third crossbar is parallel to the second crossbar. A U-shaped retaining rod is provided at the connection between the third crossbar and the second column.

[0030] Example 2

[0031] Method of using the stacked multi-layer storage tray support of the present invention:

[0032] (1) Some pallets can be placed horizontally between two first horizontal bars 2, and component pallets can also be placed horizontally between two second horizontal bars 6, thus forming a two-layer structure for placing pallets. Workers can place the pallets on the upper or lower layer. When stacking pallets, they can be stacked according to the priority of use, with the first ones placed on the upper layer and the last ones placed on the lower layer. Since there are two layers, the situation of multiple pallets being stacked together at the same time can be avoided, and the relative upper and lower positions can be adjusted as needed, so that wider ones are placed on the lower layer and smaller ones are placed on the upper layer, while also taking into account the order required for construction.

[0033] (2) During assembly, the lower end of the first column 3 is inserted into the mounting port 20 on the base plate 1 and then the two first columns 3 and the two base plates 1 are connected by the first crossbar 2. The two ends of the first arc-shaped clamping shaft 16 pass through the groove 15 and clamp and engage with the first column 3. Then the second arc-shaped clamping shaft 17 is inserted from above, so that the two ends of the second arc-shaped clamping shaft 17 are engaged with the first slot 18. The first arc-shaped clamping shaft 16 and the second arc-shaped clamping shaft 17 form a ring to connect and fix the first crossbar 2 and the first column 3 together. The base plate 1 and the first crossbar 2 are spliced ​​into a rectangle, which can then be placed on the first crossbar 2. When the base plate 1 and the first crossbar 2 are installed, the first column 3 is installed at the same time, and the second crossbar 6 is clamped and fixed between the first side support blocks 7 at the upper end of the first column 3. Then the construction pallet can be placed between the two second crossbars 6.

[0034] (3) A third layer structure can be added on the basis of the two-layer structure. A connecting shaft 5 is installed between the two ends of the two second crossbars 6. The connecting shaft 5 is fixed by two pins 12. The connecting shaft 5 is added between the two second crossbars 6 to strengthen the structure and improve stability. The connecting shaft 5 is fixed by two pins 12 to the second crossbars 6 to ensure a stable connection. Then, a second column 4 is inserted at the end of the connecting shaft 5. The four second columns 4 form the frame of the third layer. The second column 4 is connected and fixed to the connecting shaft 5 and the first column 3 by a U-shaped clamp 11. The upper end of the U-shaped clamp 11 passes through the overlapping part of the second column 4 and the first column 3. The lower end of the U-shaped clamp 11 further stabilizes the lower end of the second column 4.

[0035] A third crossbar 8 is installed between the two second side support blocks 9 at the upper end of each second column 4. The newly added tray can be placed on the two third crossbars 8. The third crossbar 8 and the second column 4 are connected and fixed by a loop-shaped clamp 10. The loop-shaped clamp 10 is sleeved on the second column 4 from top to bottom. At the same time, the two ends of the loop-shaped clamp 10 are engaged with the second slots 14 on the third crossbar 8, thereby realizing the fixed connection between the third crossbar 8 and the second column 4.

[0036] This invention has substantial features and significant technological advancements. The multi-layer stackable storage tray support of this invention adopts a detachable design, which can be disassembled from top to bottom. By pulling out the U-shaped retaining rod from the top, the third crossbar and the second column can be disassembled, as can the second column and the connecting shaft, the connecting shaft and the second crossbar. The second crossbar and the first side support block can be directly pulled upwards for disassembly. The first crossbar and the first column can be disassembled, and the first column and the base plate can be disassembled. All of these are made of detachable steel structure, which can be disassembled and stored after use, making it more convenient to carry and use, and does not take up extra space.

[0037] The above embodiments are for illustrative purposes only and are not intended to limit the invention. Those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention. Therefore, all equivalent technical solutions should also fall within the scope of this invention and are defined by the claims.
