Description

Technical Field

[0001] This utility model belongs to the field of pallet technology, specifically relating to a full honeycomb core pallet. Background Technology

[0002] During cargo transportation, to facilitate forklift handling, goods are packaged and supported by pallets at the bottom. Most existing pallets consist of a pallet plate and support columns arranged at intervals below the pallet plate. Forklift forks can freely enter and exit the intervals between adjacent columns to achieve handling. To improve strength, some pallets also have a base plate added to the bottom of the support columns, forming multiple adjacent frame structures. Forks can freely enter and exit the intervals between adjacent frame structures to achieve handling.

[0003] Because the pallet, support columns, and base plate are all solid structures, the overall weight of the pallet is large, resulting in high material consumption. To solve this problem, a solution using a honeycomb core structure in the pallet has emerged in the market to reduce weight and material consumption. However, the honeycomb core in these solutions is mostly concentrated in the panel. For example, Chinese patents CN2356953Y and CN203345330U disclose this type of pallet, which still has a large dead weight in the support columns and base plate, resulting in limited weight reduction. In addition, the honeycomb core requires additional sheet material to achieve a good connection with the support columns, resulting in many components, complex manufacturing processes, and high costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a full-cell core tray that can further reduce weight, has reliable connections, and fewer components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is a full honeycomb core tray, comprising multiple vertical pieces. Each vertical piece is bent multiple times along its length to both sides, forming multiple vertical grooves connected in sequence. The cross-section of each vertical groove is an isosceles trapezoid with an opening. The openings of adjacent vertical grooves face opposite directions. The vertical pieces are of two types: one type has only horizontally extending horizontal segments, and the other type has horizontally extending horizontal segments and vertical segments connected to the horizontal segments and extending downwards. There are at least two sets of vertical segments arranged at intervals. All the vertical pieces are staggered in their thickness direction and connected together by fusion welding, so that all the horizontal segments form a tray with multiple honeycomb holes, and all the vertical segments are concentrated below the support position of the tray to form a support column.

[0006] Preferably, the tray is rectangular, and the support position includes at least the four corners of the tray.

[0007] More preferably, the support position also includes a position located at the middle of both sides of the tray and a position at the very center of the tray.

[0008] Preferably, the vertical segment has a horizontal segment at both its upper and lower ends.

[0009] Preferably, the vertical segment has at least three sets, of which two sets are connected to the two ends of the horizontal segment along its length, and the other set is connected to the middle position of the horizontal segment along its length.

[0010] Preferably, the vertical sheet is a plastic sheet.

[0011] Preferably, the three sides of the cross-section of the vertical groove are of equal length.

[0012] Preferably, the sidewall thickness of the honeycomb pores in the vertical sheet thickness direction is twice the thickness of the other sidewalls.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] The all-honeycomb core tray provided by this utility model includes multiple vertical pieces. By bending the vertical pieces along their length multiple times to both sides, multiple vertical grooves with open isosceles trapezoidal cross-sections can be formed. The groove openings of adjacent vertical grooves face opposite directions. The vertical pieces are divided into two types: one type has only horizontally extending horizontal segments, and the other type has horizontally extending horizontal segments and vertical segments connected to the horizontal segments and extending downwards. There are at least two sets of vertical segments, which are spaced apart. All vertical pieces are staggered in their thickness direction and connected together by fusion welding. All horizontal segments form a tray with multiple honeycomb holes. All vertical segments are concentrated below the support position of the tray to form a support column, which can further reduce weight and material consumption. By using the vertical segments of one type of vertical piece to form the support column and the horizontal segments to form the tray, the tray and the support column can be well connected, the connection is reliable, and there are fewer parts and lower cost.

[0024] Example 1, as Figures 1 to 5 As shown, the all-honeycomb core tray provided by this utility model includes multiple vertical pieces. The vertical pieces are bent multiple times along their length direction to form multiple vertical grooves 1 connected in sequence. The cross-section of the vertical groove 1 is an isosceles trapezoid with an opening, and the three sides of the cross-section of the vertical groove 1 are of equal length. The groove openings of adjacent vertical grooves 1 face opposite directions. There are two types of vertical pieces. The first type of vertical piece 2 only has horizontally extending horizontal segments 3. The second type of vertical piece 4 not only has horizontally extending horizontal segments 3, but also has vertical segments 5 connected to the horizontal segments 3 and extending downward. There are three sets of vertical segments 5 arranged at intervals. Two sets are connected to the two ends of the horizontal segments 3 along their length direction, and the other set is connected to the middle position of the horizontal segments 3 along their length direction. All vertical pieces are staggered in their thickness direction and connected together by fusion welding, so that all horizontal segments 3 form a tray 7 with multiple honeycomb holes 6, and all vertical segments 4 are concentrated below the support position of the tray 7 to form a support column 8.

[0025] The advantage of this design is that not only does the tray achieve a honeycomb structure, but the support column also achieves a honeycomb structure, which can further reduce weight and material consumption. Since the vertical section 5 of the second type of vertical piece 4 forms the support column 8 and the horizontal section 3 forms the tray 7, the tray 7 and the support column 8 can form a good connection, which is reliable. Only two types of vertical pieces are needed, resulting in fewer parts and lower cost.

[0026] In this embodiment, the tray 7 is rectangular, and the support positions include at least the four corners of the tray 7, the middle positions of the two sides of the tray 7, and the position of the center of the tray 7.

[0027] In this embodiment, both the first type of vertical sheet 2 and the second type of vertical sheet 4 are plastic sheets, which are bent into vertical grooves 1 by molding. When the vertical sheets are joined together by melting and welding, the bottom wall of the vertical groove 1 is joined together with the bottom wall of the vertical groove 1 on one side, and the vertical groove 1 and the vertical groove 1 on the other side form a honeycomb hole 6, so that the side wall thickness of the honeycomb hole 6 in the thickness direction of the vertical sheet is twice the thickness of the other side walls.

[0028] Example 2, as Figures 6 to 8 As shown, Embodiment 2 is basically the same as Embodiment 1, except that in Embodiment 2, the upper and lower ends of the vertical section 5 of the second vertical piece 4 are provided with horizontal sections 3. This arrangement can further improve the structural strength of the whole honeycomb tray and enhance its load-bearing capacity.

[0029] In the above embodiments, the raw material for the vertical pieces can be plastic sheets of uniform size, which are cut according to the specific shapes of the first type and the second type of vertical pieces, and then obtained by molding. This further reduces the required components, reduces material waste, improves processing adaptability, simplifies the production process and reduces production costs. Since the supporting column is actually integrated with the support plate, the problem of weak load-bearing capacity at the connection interface in the splicing structure is avoided, and the overall mechanical performance is enhanced.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
