Description

Technical Field

[0001] The present invention relates to the technical field related to logistics pallets, and in particular to a logistics pallet plus pad device. Background Art

[0002] Pallets are the medium that transforms static goods into dynamic goods. They are a cargo platform, and they are also movable platforms, or movable ground. Even goods that lose their flexibility when placed on the ground will immediately become mobile and flexible once they are loaded on pallets, because the goods loaded on pallets are ready to move at any time. This dynamic loading and unloading method, which uses pallets as the basic tool, is called pallet operation.

[0003] The existing Chinese patent document with the announcement number CN218259298U discloses a high-pressure metal pallet, which includes a pallet body, a working support plate welded to the top of the pallet body, a non-slip bump fixedly connected to the top of the working support plate, a distribution plate welded to the inner wall of the pallet body at the bottom of the working support plate, and a connecting plate welded to the inner wall of the pallet body at the bottom of the distribution plate;

[0004] However, the pallets in the comparative documents may wear out due to various frictions during actual use, but their structures are welded together. Therefore, the entire pallet needs to be replaced after the surface is damaged, which leads to high overall replacement and maintenance costs of the pallet. For this reason, the present invention proposes a logistics pallet plus pad device to solve the above problem. Summary of the invention

[0005] The purpose of the present invention is to provide a logistics pallet and pad device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a logistics pallet pad device, comprising:

[0007] A tray body, wherein the tray body is a box structure with an open upper end surface, and a primary mounting hole is provided on the bottom surface of the tray body;

[0008] A tray leg, wherein the tray leg is integrally formed with the lower surface of the tray body, and a secondary mounting hole is provided on the tray leg, and an alignment groove is provided at the end of the secondary mounting hole;

[0009] An upper pad, the upper pad is fixed to the upper end surface of the pallet body, and a limited position seat is integrally formed on the lower surface of the upper pad at the corner position, a three-stage mounting hole is opened on the limited position seat, and a countersunk bolt hole is opened at the upper side port of the three-stage mounting hole;

[0011] The primary mounting holes, secondary mounting holes, tertiary mounting holes and bolt holes are arranged correspondingly, and the upper pad and the lower pad are positioned on the pallet body and the pallet legs by means of positioning bolts.

[0012] Preferably, the alignment groove is a regular hexagonal notch structure, the size of the alignment seat is consistent with the size of the alignment groove, and when the lower pad is actually installed, the alignment seat is embedded in the alignment groove.

[0013] Preferably, a positioning frame is integrally formed on the inner side wall of the tray body, and a reinforcement bracket is mounted on the positioning frame.

[0014] Preferably, the reinforcement bracket is composed of a reinforcement frame, a reinforcement beam and a reinforcement longitudinal beam. The reinforcement frame, reinforcement beam and reinforcement longitudinal beam are integrally formed and distributed in a grid pattern. When the reinforcement bracket is actually installed, the reinforcement frame is erected on the positioning frame, and the upper surfaces of the reinforcement frame, reinforcement beam and reinforcement longitudinal beam are flush with the upper surface of the pallet body.

[0015] Preferably, when the upper pad is actually installed, the side of the limit seat is arranged to abut against the corner of the reinforced frame.

[0016] Preferably, when the positioning bolt is actually tightened, the nut of the positioning bolt is completely screwed into the countersunk bolt hole.

[0017] Preferably, a self-locking member mounting seat is integrally formed on the lower surface of the limit seat, a spring groove is provided on the self-locking member mounting seat, a threaded hole is provided at the bottom of the spring groove, a self-locking member is installed in the spring groove, and a self-locking groove is provided on the nut of the positioning bolt.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting up a logistics pallet plus pad structure composed of a pallet body, pallet legs, an upper pad and a lower pad, the upper pad and the lower pad can replace the normal wear of the pallet body and the pallet legs, thereby avoiding the problem of high overall replacement cost after the traditional pallet structure has a wear problem;
