The sub-connecting parts at both ends of the supporting pads are respectively connected and fixed to the mother connecting parts on the first supporting layer and the second supporting layer in a manner to prevent loosening. Specifically, with respect to the connection and fixation of the above-mentioned female connector and the sub-connector, two connection methods are disclosed in the utility model. The first method adopts a connection method of a snap-fit ​​seat and a female snap-fit ​​seat, wherein an elastic clamping block is provided at one end of the snap-fit ​​seat, and an end clamping block is provided at the other end. A snap-fitting groove is provided in the female snap-fit ​​seat, and an inwardly recessed clamping groove is provided on the inner wall of the snap-fitting groove. During the assembly process, the snap-fit ​​seat can be pushed into the snap-fitting groove by rotating or linear pushing.

The second type adopts a connection method in which the sub-buckle block and the mother buckle block are fastened to each other. The sub-buckle block can be set on the support pad, and the mother buckle block can be set on the first support layer or the second support layer. An inclined plane is provided on the side of the sub-buckle block to be connected, and a plurality of latching teeth are provided on the inclined plane from top to bottom. Similarly, an inclined plane with the same inclination direction as the inclined plane of the sub-buckle block is also provided on the side of the mother buckle block to be connected, and a plurality of latching teeth are also provided on the inclined plane from top to bottom. During the assembly process, the sub-buckle block is inserted into the buckle groove of the mother buckle block along the vertical direction. As the sub-buckle block is inserted, the latching teeth of the sub-buckle block slide on the latching teeth of the mother buckle block until the installation is completed. The latching teeth of the sub-buckle block and the mother buckle block are fixed to each other. This assembly method with latching teeth can only push the sub-buckle block in one direction from the assembly direction, and the sub-buckle block cannot move in the opposite direction, that is, the assembly anti-loosening function is also realized, effectively ensuring the connection stability. In addition, the first supporting layer and the second supporting layer of the utility model can adopt an overall rectangular plate-like structure design, by opening hollow holes thereon to reduce the manufacturing materials, and can also adopt a structure composed of multiple transverse plates and longitudinal plates extending in the longitudinal and transverse directions respectively, and the connection method between the transverse plates and the longitudinal plates can adopt the connection of the above-mentioned sub-buckle blocks and female buckle blocks, or can adopt the mutual plug-in of plug-in blocks and sockets, and assisted by elastic stop blocks for assembly limit clamping, to prevent loosening.

[0098] The utility model designs a new type of combined pallet that connects a first support part and a second support part that are arranged in parallel and spaced apart from each other by multiple support pads, realizes the disassembly manufacturing of parts, reduces the production cost and the storage and transportation cost in the later stage, and has a firm connection and anti-loosening function. The utility model as a whole comprises a second support layer and a first support layer that are arranged in spaced apart from each other, and the first support layer and the second support layer are connected and fixed by multiple support pads, so as to assemble to form a complete pallet, and sub-connectors are provided at both ends of the support pads, and the sub-connectors at both ends of the support pads are respectively connected and fixed to the mother connectors on the first support layer and the second support layer in an anti-loosening manner. Specifically, with respect to the connection and fixation of the above-mentioned female connector and the sub-connector, two connection methods are disclosed in the utility model. The first method adopts a connection method of a snap-fit ​​seat and a female snap-fit ​​seat, wherein an elastic clamping block is provided at one end of the snap-fit ​​seat, and an end clamping block is provided at the other end. A snap-fitting groove is provided in the female snap-fit ​​seat, and an inwardly recessed clamping groove is provided on the inner wall of the snap-fitting groove. During the assembly process, the snap-fit ​​seat can be pushed into the snap-fitting groove by rotating or linear pushing. In the process of the snap-fitting seat entering the snap-fitting groove, the elastic clamping block is gradually pressed by the groove wall of the snap-fitting groove until the elastic clamping block is completely inserted into the snap-fitting groove, and the elastic force provided by the elastic clamping block after being pressed is pressed against the inner wall of the snap-fitting groove, thereby completing the first level of reinforcement of the connection. At the same time, when the snap-fit ​​seat is completely inserted into the snap-fitting groove, the end clamping block provided at the other end of the snap-fitting seat is correspondingly embedded in the clamping groove, and the position of the snap-fit ​​seat is limited and clamped by the end clamping block, thereby completing the second level of reinforcement of the connection, thereby preventing the snap-fitting seat from slipping out of the snap-fitting groove during use, thereby playing a role in preventing the connection from loosening. The second type adopts a connection method in which the sub-buckle block and the mother buckle block are fastened to each other. The sub-buckle block can be set on the support pad, and the mother buckle block can be set on the first support layer or the second support layer. An inclined plane is provided on the side of the sub-buckle block to be connected, and a plurality of latching teeth are provided on the inclined plane from top to bottom. Similarly, an inclined plane with the same inclination direction as the inclined plane of the sub-buckle block is also provided on the side of the mother buckle block to be connected, and a plurality of latching teeth are also provided on the inclined plane from top to bottom. During the assembly process, the sub-buckle block is inserted into the buckle groove of the mother buckle block along the vertical direction. As the sub-buckle block is inserted, the latching teeth of the sub-buckle block slide on the latching teeth of the mother buckle block until the installation is completed. The latching teeth of the sub-buckle block and the mother buckle block are fixed to each other. This assembly method with latching teeth can only push the sub-buckle block in one direction from the assembly direction, and the sub-buckle block cannot move in the opposite direction, that is, the assembly anti-loosening function is also realized, effectively ensuring the connection stability. In addition, the first supporting layer and the second supporting layer of the utility model can adopt an overall rectangular plate-like structure design, by opening hollow holes thereon to reduce the manufacturing materials, and can also adopt a structure composed of multiple transverse plates and longitudinal plates extending in the longitudinal and transverse directions respectively, and the connection method between the transverse plates and the longitudinal plates can adopt the connection of the above-mentioned sub-buckle blocks and female buckle blocks, or can adopt the mutual plug-in of plug-in blocks and sockets, and assisted by elastic stop blocks for assembly limit clamping, to prevent loosening.

Those skilled in the art can make certain modifications inspired by this embodiment. Therefore, all equivalent changes or modifications made in accordance with the scope of the present utility model patent fall within the scope of the claims of the present utility model patent.
