Description

Technical Field

[0001] This utility model relates to the field of logistics equipment, and in particular to a thermoplastic honeycomb logistics pallet. Background Technology

[0002] Plastic honeycomb panels are typically made from plastics such as polypropylene (PP) or polyethylene (PE). They are formed into a honeycomb structure through a process, and flat plates are laminated on the upper and lower surfaces to create a lightweight panel. Combining the mechanical advantages of honeycomb structures with the lightweight, corrosion-resistant, and flame-retardant properties of plastics, they are a high-performance composite material.

[0003] In the prior art, the inventor disclosed a thermoplastic honeycomb molding die, which is a Chinese invention patent with application number "CN202111364487.8". It forms a honeycomb-shaped panel structure by folding the honeycomb in the horizontal direction. Traditional panels are generally used as structural or decorative panels only by cutting and other processing methods. Since thermoplastic honeycomb panels have high structural strength, they can be used as trays. The prior art usually uses glued cut panels as the bottom legs of the tray. However, the sides of the honeycomb structure legs expose the internal cavity. At the same time, the strength of multi-layer hot-melt or glued legs is insufficient. Therefore, there is a need for a structure that applies the honeycomb structure to the tray. Utility Model Content

[0004] The purpose of this utility model is to provide a thermoplastic honeycomb logistics pallet, which replaces the support legs by opening holes in the pallet and nesting support cylinders, and replaces the bonding of the sheet metal by fixing the structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a thermoplastic honeycomb logistics pallet, including a pallet plate, an upper through hole through the pallet plate, a support plate below the pallet plate, the support plate and the pallet plate being honeycomb panels, the support plate extending along the length direction of the panel body, the support plate being evenly distributed along the width direction of the panel body, a lower through hole through the support plate, the upper through hole and the lower through hole corresponding one-to-one, the upper through hole being located at the corner, center, midpoint of the long side and midpoint of the short side of the pallet plate, an upper connecting cover being provided in the upper through hole, a lower support seat being provided in the lower through hole, a support cylinder being provided between the upper connecting cover and the lower support seat, the top of the support cylinder abutting against the bottom of the pallet plate, an upper clamping groove cooperating with the upper connecting cover being concentrically provided at the top of the upper through hole, a lower clamping groove cooperating with the lower support seat being concentrically provided at the bottom of the lower through hole, the bottom of the upper connecting cover being connected to the top of the support cylinder, and the top of the lower support seat being connected to the bottom of the support cylinder.

[0006] Preferably, the lower part of the upper connecting cover is threaded to the inner side of the top of the support cylinder.

[0007] By adopting the above technical solution, the threaded connection serves to clamp and fix the upper connecting cover, support cylinder and tray, which facilitates quick disassembly. The threaded connection provides a certain preload, which improves the structural strength and connection strength, and facilitates subsequent maintenance and replacement.

[0008] Preferably, the top of the upper connecting cover is provided with a semi-circular groove for inserting a hand. The upper connecting cover is circular, and two semi-circular grooves are symmetrically arranged on the top of the upper connecting cover. The semi-circular grooves are recessed downward along the upper surface of the upper connecting cover.

[0009] By adopting the above technical solution, the semi-circular groove facilitates the installer or equipment to rotate the upper connecting cover, and also makes it easy for the operator to tighten it by hand, simplifying the installation and disassembly process.

[0010] Preferably, the upper connecting cover includes a flange, an upper connecting tube, and a reinforcing plate. The two sides of the reinforcing plate in the width direction are respectively connected to the inner side of the upper connecting tube. The reinforcing plate extends along the length direction of the upper connecting tube. The flange is formed by extending outward in the horizontal direction from the upper surface of the upper connecting tube. The semi-circular grooves are respectively provided on both sides of the reinforcing plate in the horizontal direction. The lower outer side of the upper connecting tube is provided with an external thread that mates with the support cylinder.

[0011] By adopting the above technical solution, the flange increases the contact area between the upper clamping grooves, improving the stability of the fixation; the reinforcing plate enhances the structural rigidity of the upper connecting cover itself, improves the structural strength at the top of the pallet, and reduces and avoids deformation after being subjected to pressure.

[0012] Preferably, the upper part of the lower support base is threaded or interference-fitted to the inner side of the lower part of the support cylinder.

[0013] By adopting the above technical solution, various connection and fixing methods for the lower support base are disclosed. The interference fit structure has higher strength, but disassembly is difficult.

[0014] Preferably, the lower support includes a bottom edge, a base plate, and a lower connecting pipe. The bottom of the lower connecting pipe is integrally formed with the top of the base plate. The lower connecting pipe is concentrically arranged with the base plate and mates with a lower through hole. The bottom edge extends outward in the horizontal direction along the edge of the base plate. The outer side of the upper part of the lower connecting pipe is provided with an external thread that mates with the support cylinder.

[0015] By adopting the above technical solution, the bottom edge structure can better embed the lower support seat into the support plate and distribute the pressure on the support plate. At the same time, it is disclosed that the lower connecting pipe is connected to the support cylinder by a threaded connection.

[0016] Preferably, the bottom of the support plate is provided with an upper positioning groove, which is formed by a recess in the lower surface of the support plate. The upper positioning groove is fitted into the top of the support cylinder and is concentric with the upper through hole. The top of the support plate is provided with a lower positioning groove, which is fitted into the bottom of the support cylinder and is aligned with the lower through hole. The lower positioning groove is formed by a downward recess in the top of the support plate.

[0017] By adopting the above technical solution, the upper and lower positioning grooves play a role in initial positioning and auxiliary support during the installation process, and play a role in pre-positioning before tightening the external thread.

[0018] Preferably, the bottom of the base plate is provided with a groove, a foot pad is provided in the groove, a locking block is provided on the top of the foot pad, and a locking hole is provided in the groove to cooperate with the locking block.

[0019] By adopting the above technical solution, friction is increased to prevent the tray from sliding, and the foot pads can be quickly connected through the locking holes and locking blocks.

[0020] Preferably, the bottom of the foot pad protrudes outward, and the support plate is distributed in a crisscross shape at the bottom of the support plate.

[0021] By adopting the above technical solution, the contact area between the pallet and the ground is increased, the support effect is improved, and the pallet can be inserted into the bottom of the pallet by forklifts.

[0022] In summary, both the support plate and the pallet are made of honeycomb panels, which have high structural strength but are difficult to process. In terms of processing, only upper and lower through holes are cut. Simultaneously, the top of the pallet is heat-pressed and deformed in the height direction to form an upper clamping groove, and the bottom of the lower support base is heat-pressed to form a lower clamping groove. The cut upper and lower through holes reduce the difficulty of heat-pressing the upper and lower clamping grooves, upper and lower positioning grooves. The support legs are formed by three parts: an upper connecting cover, a lower support base, and a support cylinder. Compared to traditional adhesive bonding, this facilitates installation and disassembly. The entire structure, through the support cylinder's abutment in the height direction, forms an internal support skeleton, effectively distributing the load on the pallet to the ground, resulting in a more stable structure. Furthermore, the upper and lower clamping grooves ensure that the upper connecting cover and lower support base can be accurately positioned and fixed within the mounting holes, preventing displacement and rotation under stress and ensuring assembly accuracy and reliability.
