DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, a paper tray for printing in the figure includes a support plate 1 and a clamping mechanism arranged inside the support plate 1, and the clamping mechanism includes a working component and a clamping component;

[0025] The working assembly includes a hydraulic box 2 and a hydraulic rod 3. The hydraulic box 2 is arranged inside the support plate 1, and the hydraulic rod 3 is arranged inside the hydraulic box 2.

[0026] The clamping assembly includes a clamping block 4, a connecting rod 5 and a fixed block 6. The outer wall of the hydraulic rod 3 is rotatably connected to the clamping block 4, the outer wall of the clamping block 4 is rotatably connected to the connecting rod 5, and the top of the hydraulic box 2 is fixedly connected to the fixed block 6.

[0027] Among them, Figure 3 As shown, the clamping block 4 forms a clamping structure through the hydraulic rod 3 and the connecting rod 5, which is conducive to driving the clamping block 4 to rotate under the action of the hydraulic rod 3. At the same time, the connecting rod 5 will also rotate to play a connecting and supporting role for the clamping block 4, so that the clamping block 4 can have a more stable clamping operation on the paper above the paper tray 15, avoiding damage caused by the paper falling off the tray due to road bumps during transportation.

[0028] Among them, Figure 3 As shown, the connecting rod 5 forms a rotating structure through the clamping block 4 and the fixing block 6. The rotation of the clamping block 4 will drive the connecting rod 5 to rotate. At the same time, the connecting rod 5 is fixed on the fixing block 6, which plays a certain supporting and connecting role for the clamping block 4.

[0029] Among them, Figure 2As shown, there are two groups of clamping blocks 4, and the position relationship of the two groups of clamping blocks 4 is relatively symmetrical about the midpoint of the support plate 1. The two groups of clamping blocks 4 are advantageous in that the paper can be clamped from both sides, preventing the paper from being not well clamped on only one side, thereby realizing multi-angle clamping operation of the paper.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the present embodiment further illustrates Example 1, a first fixed slot block 7 is provided at the lower end of the pallet 1, a locking column 8 is fixedly connected to the inner wall of the first fixed slot block 7, a second fixed slot block 9 is fixedly connected to the outer wall of the pallet 1, a fixed slot column 10 is fixedly connected to the inner wall of the second fixed slot block 9, a rotating slot block 11 is rotatably connected to the inner wall of the fixed slot column 10, a rotating shaft 12 is rotatably connected to the inner wall of the second fixed slot block 9, a rotating buckle 13 is fixedly connected to one end of the rotating shaft 12, a foot pier 14 is fixedly connected to the bottom end of the pallet 1, and a paper tray 15 is fixedly connected to the inner wall of the pallet 1.

[0032] Among them, Figure 4 As shown, the first fixed slot block 7 forms a snap structure with the second fixed slot block 9 through the snap-fit ​​column 8, the rotating slot block 11 and the rotating buckle 13, which is conducive to twisting the rotating buckle 13 so that the rotating slot block 11 can pass through the outside of the rotating buckle 13, so that the circular groove set inside the rotating slot block 11 is snapped on the snap-fit ​​column 8, and then the rotating buckle 13 is rotated 90 degrees to snap the rotating slot block 11. When the paper tray is not in use, multiple groups of paper trays can be combined together by fixing the first fixed slot block 7 and the second fixed slot block 9.

[0033] Among them, Figure 1 As shown, the rotating buckle 13 fits tightly with the groove surface set inside the rotating slot block 11, which is beneficial for preventing the rotating slot block 11 from rotating by twisting the rotating buckle 13 after the rotating slot block 11 is engaged through the engaging column 8. The design of the rotating buckle 13 can provide a stable engaging operation for the rotating slot block 11.

[0034] When in use: First, under the action of the hydraulic rod 3, the clamping block 4 will be driven to rotate, and at the same time, the connecting rod 5 will also rotate to connect and support the clamping block 4. The design of the two groups of clamping blocks 4 is conducive to clamping the paper from both sides, preventing the paper from being unable to be well clamped on one side, and realizing multi-angle clamping operation on the paper above the paper tray 15, avoiding damage caused by the paper falling off the tray due to road bumps during transportation.

[0035] Finally, when the paper trays are not in use, multiple sets of paper trays can be stacked together. The rotating buckle 13 can be twisted to allow the rotating slot block 11 to pass through the outside of the rotating buckle 13, so that the circular groove set inside the rotating slot block 11 is engaged on the engaging column 8, and then the rotating buckle 13 is rotated 90 degrees to engage the rotating slot block 11. The multiple sets of paper trays can be combined together through the fixing operation of the first fixed slot block 7 and the second fixed slot block 9 to prevent the collapse of the paper trays due to instability when stacking. The design of the buckle is conducive to the stable storage operation of multiple sets of paper trays.
