[0001] The utility model belongs to the technical field of pallets, in particular to a fumigation-free pallet with a support plate fixing structure. Background Art

[0002] A pallet is a medium that turns static cargo into dynamic cargo. To improve the pest-proof performance of pallets, fumigation-free pallets have been developed on the market. Fumigation-free pallets are specially treated to avoid the fumigation process. Fumigation-free pallets are made of high-strength composite materials and have the characteristics of light weight, strong load-bearing capacity, corrosion resistance, and pest resistance.

[0003] Fumigation-free pallets are mainly assembled from support plates, legs, base plates and bolts. The size and shape of fumigation-free pallets can be customized according to customer needs and have a wide range of applications.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. During the assembly process of existing fumigation-free pallets, bolts are used to fix the bottom plate and the legs, thereby improving the stability of the bottom plate and the legs after connection. However, due to the large number of bolts, the number of steps required for disassembly and assembly of the bottom plate and the legs increases, which increases the workload of the workers when assembling the bottom plate and the legs. In addition, external devices are required for disassembly and assembly of the bottom plate and the legs.

[0006] 2. In the existing fumigation-free pallet, during the assembly process, the pallet is locked and connected to the support legs by bolts, but it is not convenient to position the pallet and the support legs, which will cause the assembly position of the pallet and the support legs to be misaligned. In addition, a large number of bolts are used, which makes it inconvenient to quickly disassemble and assemble the pallet.

[0007] To this end, we provide a fumigation-free pallet with a pallet fixing structure to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a fumigation-free pallet with a support plate fixing structure. By arranging a support leg assembly and a support support assembly, the problem that the existing fumigation-free pallet is inconvenient to disassemble and assemble between the bottom plate and the support legs, and it is inconvenient to position and fix the support plate and the support legs is solved.

[0009] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] The top end of the lifting block is fixedly mounted on the support leg, and the bottom end of the lifting block is fixedly mounted on the support leg, and the support leg is fixed with a fixed position to the support leg.

[0011] The present invention is further configured such that the number of the internal threaded hole grooves is equal to the number of the supporting legs, the positions of the supporting legs correspond one-to-one to the positions of the internal threaded hole grooves, and the depth dimension of the internal threaded hole grooves is equal to the length dimension of the protruding rod.

[0012] The present invention is further configured such that three slide bars are provided, the slide bars are T-shaped, and the slide grooves are T-shaped.

[0013] The present invention is further configured such that a positioning rod is fixedly connected to the side wall of the fixed stopper, and the positioning rod is plugged into a positioning hole formed at one end of the sliding rod.

[0014] The utility model is further configured as follows: a limiting component is provided on the side wall of the movable stopper, a limiting groove is provided on the side wall of the movable stopper, a through groove provided on the side wall of the movable stopper is connected to the limiting groove, an insertion rod in the limiting component passes through the limiting groove and the through groove, a protruding handle is fixed to the end of the insertion rod, a reset spring is sleeved on the peripheral side wall of the insertion rod, and the insertion rod is plugged into the socket provided at the other end of the sliding rod.

[0015] The present invention is further configured such that one end of the return spring is connected to the side wall of the limiting groove, and the other end of the return spring is connected to the side wall of the cam.

[0016] The present invention is further configured such that the outer diameter of the cam is larger than the inner diameter of the limiting groove, and the length of the return spring is equal to the depth of the limiting groove.

[0017] The present invention is further configured such that the inner diameter of the limiting groove is equal to twice the inner diameter of the through groove, the sum of the depth of the limiting groove and the depth of the through groove is equal to the depth of the insertion hole, and the length of the insertion rod is equal to twice the depth of the insertion hole.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model sets a support assembly and rotates the support leg.
