Wherein, a plurality of locking mechanisms are provided, and the locking mechanisms are provided on the first assembly and the first support plate, the second assembly and the second support plate, and the first assembly and the second assembly.

By adopting the above-mentioned logistics transport pallet, the first support plate and the second support plate can be spliced together through the setting of the combination mechanism, and the combination mechanism includes a first assembly and a second assembly. The cross-sections of the first assembly and the second assembly are both trapezoidal, which can be adapted to the trapezoidal mounting grooves on the first support plate and the second support plate. When assembling, the first assembly is installed on the first support plate and fixed by the locking mechanism, the second assembly is installed on the second support plate and fixed by the locking mechanism, and then the first assembly is connected to the second assembly and fixed by the locking mechanism, thereby completing the installation. When disassembly is required, only the locking mechanism needs to be disassembled, which is quick and convenient.

At the same time, by disassembling the locking mechanism on the first assembly and the second assembly, the position between the first assembly and the second assembly can be adjusted, so that the overall width of the pallet can be adjusted to meet the needs of different sizes. Moreover, through the setting of the locking mechanism, the first support plate, the second support plate, the first assembly and the first support plate can be protected during disassembly to prevent damage after multiple disassembly and installation.

Furthermore, the second assembly is provided with a slot, the first assembly is provided with an insertion rod matched with the slot, and the slot and the insertion rod are fixed by a locking mechanism.

By setting the slot and the insertion rod, the first assembly and the second assembly can be matched together to form a plug-in structure, so that the position between the first assembly and the second assembly can be adjusted easily. After the adjustment is completed, it can be fixed by a locking mechanism, which is very convenient.

Further: the locking mechanism comprises:

A bottom groove is disposed at the bottom of the second assembly;

A matching plate is disposed in the bottom groove, and a threaded hole is disposed on the matching plate;

A first guide hole, disposed on the slot and connected to the threaded hole;

A second guide hole is provided on the insertion rod and communicated with the first guide hole;

When installing the components, it is only necessary to pass the fastening bolts through the fourth guide hole, the third guide hole, the second guide hole, and the first guide hole, and finally match them with the threaded holes. In the present application, only the threaded holes on the mating plate are threadedly matched with the fastening bolts, and the inner diameters of the first guide holes and the second guide holes are the diameters of the fastening bolts. Therefore, only the fastening bolts and the threads on the mating plate are worn during installation or disassembly, and other components will not be damaged, thereby avoiding the problem of loose installation due to damaged threads. At the same time, the damaged fastening bolts and mating plates are replaceable parts, and the replacement cost is low. Even if they are damaged, they will not cause much loss after replacement, which effectively reduces the loss and protects the pallet.

A first auxiliary ring is provided on the fastening bolt, the first auxiliary ring is installed on the rod of the fastening bolt, the second auxiliary ring is installed on the inner wall of the first guide hole, and the auxiliary spring is sleeved on the fastening bolt. Through the gradual cooperation between the fastening bolt and the threaded hole, the auxiliary spring will be compressed by the first auxiliary ring and the second auxiliary ring, and finally be in a compressed state. When the fastening bolt is removed, the auxiliary spring will reset and provide elastic force for the first auxiliary ring, thereby assisting the user to remove the fastening bolt, thereby improving the disassembly efficiency. In addition, since the diameter of the first auxiliary ring is larger than the inner diameter of the fourth guide hole, the first auxiliary ring can play a certain limiting role to prevent the tightening bolt from being removed when the locking cover is not removed.

Furthermore, the first support plate and the second support plate are both provided with support protrusions for supporting the first assembly and the second assembly.

By setting a supporting protrusion on the first supporting plate, the first assembly can be supported, and by setting a supporting protrusion on the second supporting plate, the second assembly can be supported.

The beneficial effects of this application are:

1. By disassembling the locking mechanisms on the first assembly and the second assembly, the position between the first assembly and the second assembly can be adjusted, so that the width of the entire tray can be adjusted to meet the needs of different sizes. Moreover, through the setting of the locking mechanism, the first support plate, the second support plate, the first assembly and the first support plate can be protected during disassembly to prevent damage after multiple disassembly and installation;

2. In the present application, only the threaded hole on the matching plate is threadedly matched with the fastening bolt, and the inner diameter of the first guide hole and the second guide hole is the diameter of the fastening bolt. Therefore, whether in the process of installation or disassembly, only the fastening bolt and the thread on the matching plate are worn, and other parts will not be damaged, thereby avoiding the problem of loose installation due to damaged threads. At the same time, the damaged fastening bolt and matching plate are both replaceable parts, and the replacement cost is low. Even if they are damaged, they will not cause much loss after replacement, which effectively reduces the loss and protects the pallet.

3. Through the setting of the first auxiliary ring, the second auxiliary ring and the auxiliary spring, and through the gradual cooperation between the fastening bolt and the threaded hole, the auxiliary spring will be compressed by the first auxiliary ring and the second auxiliary ring, and finally be in a compressed state. When removing the fastening bolt, the auxiliary spring will reset and provide elastic force for the first auxiliary ring, thereby assisting the user to remove the fastening bolt, thereby improving the disassembly efficiency.
