[0029] The processing and installation principle of a new type of metal mortise and tenon pallet frame in this utility model:

[0030] When processing the new metal mortise and tenon pallet frame, please see the attached Figure 1 and 6 -9. Since only the middle support block is cut, it is mainly described by the state change of the middle support block. In the first step of processing, the left and right sides of the middle support block are first cut vertically to half the height of the left support block and the right support block, and then the cut interface is horizontally cut at the midpoint of the front-to-back direction. Then, the cut surface (that is, the sandwich surface that is then bent downward and inward) is pressed inward with the help of an external weight to form a sandwich. At this time, the process needs to be checked, that is, the first pressing surface and the second pressing surface need to be ensured to be horizontal. After the assembly is completed, the contact force-bearing edge of the upper end of the sandwich and the bottom force-bearing edge of the lower end of the sandwich are formed, thereby realizing upper and lower end support. During the overall installation, the two installation components are formed into a cross buckle operation. After the upper installation component and the lower installation component are installed, the two sandwich parts are partially fitted and form a "cross". This design method can increase the contact force area, make the pressure distribution more uniform, and at the same time better extend the service life of this product.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
