Description

Technical Field

[0001] This utility model belongs to the field of material bins, and specifically relates to a material bin with adjustable space. Background Technology

[0002] Tote boxes are critical logistics tools in manufacturing industries (such as automotive parts handling) used for storing and transporting loose parts, protecting stored goods and ensuring their orderly flow. However, traditional tote boxes have fixed volumes. When the load is insufficient, the large internal gaps can easily cause parts to shake and collide during transportation, resulting in scattering or damage, affecting efficiency and quality. Furthermore, to accommodate different load capacities or special parts, various sizes of tote boxes need to be customized. This leads to high procurement and management costs, low tote box asset utilization, and difficulty in meeting the needs of flexible production. In addition, when unloaded, even when stacked, the fixed-structure tote boxes have limited volume reduction, occupying a significant amount of valuable warehouse space and return transport capacity, significantly increasing warehousing and logistics costs.

[0003] Therefore, there is an urgent need for a bin structure that can flexibly adjust the loading space and significantly reduce the volume of the empty bin. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a space-adjustable bin, which not only allows for flexible adjustment of the device space according to the amount of parts loaded, making it suitable for loading parts of various specifications, but also reduces the volume occupied by the bin when empty by folding, thereby improving transport capacity.

[0005] The main technical solution adopted in this utility model is as follows:

[0006] An adjustable-space bin includes a base plate, two side plates, a first folding plate, and a second folding plate. The two side plates are arranged opposite each other on the base plate, and the first and second folding plates are also arranged opposite each other on the base plate. The base plate, the two side plates, the first folding plate, and the second folding plate form a top-open accommodating space. The base plate has a plurality of arranged insertion holes on the side near the first folding plate, and the arrangement of the insertion holes is parallel to that of the side plates. The bottom of the first folding plate has an insertion rod for engaging with the insertion holes on the base plate. Both sides of the first and second folding plates have a plurality of pins for engaging with the side plates. The side plates have a plurality of pin holes on the side near the first folding plate, and the pin holes correspond one-to-one with the insertion holes.

[0007] Preferably, both the first folding plate and the second folding plate include an upper folding plate and a lower folding plate. The upper folding plate and the lower folding plate are connected by a number of hinge connectors to achieve vertical folding. Both sides of the upper folding plate and the lower folding plate are provided with pins for insertion into the side plates.

[0008] Preferably, the upper ends of both sides of the lower folding plate of the second folding plate are provided with limit rods, and limit blocks are provided on the side plates on both sides. The limit rods are installed in conjunction with the limit grooves on the limit blocks.

[0009] Preferably, positioning blocks are provided on both sides of the bottom end of the side plate, and bottom posts are provided at the four corners of the bottom plate for inserting the two side plates, the first folding plate and the second folding plate. A positioning groove with a vertical opening is provided on one side of the bottom post for cooperating with the positioning blocks.

[0010] Preferably, the bottom of both sides of the base plate is provided with support frames, and the support frames are open support frames, and the two sides are integrally folded to form a double-sided structure.

[0011] Beneficial effects: This utility model provides a space-adjustable material bin, which has the following advantages:

[0012] (1) This utility model can conveniently adjust the material box's capacity by connecting the first folding plate with the insertion hole on the bottom plate and the pin hole on the side plate, thus adapting to various loading requirements.

[0013] (2) In this utility model, the first folding plate and the second folding plate can be folded by hinge connectors, and all the plates can be disassembled and placed on the base plate after folding, which significantly reduces the space occupied in the unloaded state.

[0014] (3) In this utility model, the side of the support frame adopts an integral folding and forming double-sided structure (forming a trapezoidal cross section), which effectively enhances the strength and load-bearing capacity of the support frame, and can well limit the folded state and the full stacking state, ensuring the stability of the material box stacking and avoiding the scattering of the stack during transportation.

[0027] like Figure 1-2As shown, a space-adjustable hopper includes a base plate 1, two side plates 2, a first folding plate 3, and a second folding plate 4. The two side plates 2 are arranged opposite each other on the base plate 1, and the first folding plate 3 and the second folding plate 4 are also arranged opposite each other on the base plate 1. The base plate 1, the two side plates 2, the first folding plate 3, and the second folding plate 4 form a top-open receiving space. A plurality of insertion holes 1-1 are arranged on the side of the base plate 1 near the first folding plate 3, and the insertion holes 1-1 are arranged parallel to each other on the side plates 2. Several pin holes 2-1 are provided on the side of the two side plates 2 near the first folding plate 3, and the pin holes 2-1 on the two side plates 2 correspond one-to-one. The bottom of the first folding plate 3 is provided with a plug rod 3-1 for insertion into the plug hole 1-1 on the bottom plate 1. Several pins 3-2 are provided on both sides of the first folding plate 3 and the second folding plate 4, respectively, for insertion into the two side plates. Several pin holes 2-1 are provided on the side of the two side plates 2 near the first folding plate 3, and the pin holes 2-1 correspond one-to-one with the plug hole 1-1.

[0028] In this invention, the number of insertion holes 1-1 and pin holes 2-1 can be selectively designed according to actual needs. The number of rows of insertion holes 1-1 can also be selectively set according to actual needs, ensuring that the number of insertion rods 3-1 is consistent with the number of rows of insertion holes 1-1. In this embodiment 1, the number of insertion rods is 1, so the number of rows of insertion holes 1-1 is also 1.

[0029] like Figure 3 As shown, both the first folding plate 3 and the second folding plate 4 include an upper folding plate 3-3 and a lower folding plate 3-4. The upper folding plate 3-3 and the lower folding plate 3-4 are connected by several hinge connectors 3-5 to achieve vertical folding. Both sides of the upper folding plate 3-3 and the lower folding plate 3-4 are provided with pins 3-2 for insertion into the side plate 2.

[0030] like Figure 4 As shown, limit rods 4-1 are provided on the upper ends of both sides of the lower folding plate 3-4 of the second folding plate 4, and limit blocks 2-2 are provided on the side plates 2 on both sides. The limit rods 4-1 are installed in conjunction with the limit grooves 2-21 on the limit blocks 2-2. In this utility model, the limit rods 4-1 are detachably connected and positioned by inserting into the limit grooves 2-21 on the limit blocks 2-2.

[0031] like Figure 5 As shown, positioning blocks 2-3 are respectively provided on both sides of the bottom end of the side plate 2, and bottom posts 1-2 are provided at each of the four corners of the bottom plate 1 for inserting the two side plates 2, the first folding plate 3, and the second folding plate 4. A vertically open positioning groove 1-21 is provided on one side of the bottom post 1-2 for engaging the positioning blocks 2-3. In this embodiment, the sides of each plate can be inserted into the slots of the bottom posts 1-2, and the side plates 2 achieve precise alignment and detachable installation through the engagement of the positioning blocks 2-3 and the positioning grooves 1-21.

[0032] like Figure 6 As shown, support frames 5 are installed on both sides of the bottom of the base plate 1. These support frames are manufactured using an integrated folding forming process, with their two sides folded outwards and upwards to form a double-sided structure. This not only creates a downward-opening trapezoidal vertical cross-section but also significantly improves the strength of the support frame. This trapezoidal opening design allows it to securely fit with the frame sides of the stacking bins, enabling bin stacking.

[0033] In this embodiment, the material box dimensions are 800×1000×803mm (length×width×height). For vehicles with a general width of 2.45 meters, three rows can be loaded longitudinally; if a 17.5-meter flatbed truck with a width of 3 meters is used, the material boxes can be arranged laterally in three rows. This design is compatible with various transport vehicle types and achieves efficient utilization of transport space.

[0034] In this invention, the box body is installed using an inner keyway structure (e.g., a limiting groove 2-21 and a limiting rod 4-1, a positioning groove and a positioning block 2-3) and an internal connection structure (e.g., a support frame that can be used for stacking), which effectively compresses the outer dimensions of the box while ensuring the internal space of the box.

[0035] The method of using this utility model is as follows:

[0036] Adjusting the bin volume: First, open the pin 3-2 on the first folding plate 3 to separate it from the side plates 2 on both sides; then lift the first folding plate 3, select the appropriate insertion hole 1-1 on the base plate 1 according to the target volume, and insert it to fix it; finally, reinsert the pin 3-2 of the first folding plate 3 into the pin holes 2-1 on both side plates 2 and lock it in place. This completes the adjustment of the bin space. After the bins are full, they can be stacked vertically, such as... Figure 7 As shown, make full use of storage / transportation space.

[0037] Folding the empty hopper: First, open the latches 3-2 on the first folding plate 3 and the second folding plate 4, lift them up, and completely separate them from the side plates 2 on both sides; then, using the hinge connectors 3-5, fold and stack the upper folding plate 3-3 and the lower folding plate 3-4 of the first folding plate 3 respectively, and similarly fold and stack the upper and lower parts of the second folding plate 4; next, place the folded first folding plate 3 and the second folding plate 4 on the base plate 1; finally, lift the two side plates 2 and stack them upwards on the folding plate assembly already placed on the base plate 1, thus completing the folding and storage of the entire hopper. The folded and stored hopper can be stacked vertically, such as... Figure 8 As shown.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
