[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] During specific implementation: As Figures 1-4 shown, a plastic suction tray structure with an upper and lower three-dimensional multi-cavity design includes:

[0021] A base 10, a lower tray 11 is installed through the top of the base 10, and an upper tray 12 is installed on the top of the lower tray 11;

[0022] A support mechanism 20 is installed through the surface of the base 10 and can support and limit the upper tray 12;

[0023] Among them, the support mechanism 20 includes two mounting seats 21 fixedly installed on one side of the base 10 and the upper tray 12, a plastic shaft piece 22 is fixedly installed between the two mounting seats 21, and support assemblies 23 are installed through both sides of the base 10. The support assemblies 23 are installed through both sides of the base 10 and can support and limit the upper tray 12.

[0024] As Figure 2 、 Figure 3 and Figure 4As shown in the figure, the support assembly 23 includes a piston cylinder 231 penetrating and installed around the top of the lower tray 11. A piston plate 232 is slidably installed inside the piston cylinder 231. A piston rod 233 is fixedly installed at the top of the piston plate 232. The top end of the piston rod 233 penetrates the piston cylinder 231 and extends to the top of the piston cylinder 231. A pressure plate 234 is fixedly installed at the top of the piston rod 233. A first return spring 235 is fixedly installed at the bottom of the piston plate 232. The bottom end of the first return spring 235 is fixedly installed at the bottom of the inner cavity of the piston cylinder 231. Sealing shells 236 are penetratingly installed on both sides of the base 10. A rectangular plate 237 is slidably installed inside the sealing shell 236. Vertical rods 238 are fixedly installed on both sides of the top of the rectangular plate 237. The top ends of the vertical rods 238 penetrate the sealing shell 236 and extend to the top of the sealing shell 236. A top plate 239 is fixedly installed at the top ends of the vertical rods 238. Air pipes 2301 are communicated and installed on the front and back sides of the sealing shell 236. One end of the air pipe 2301 away from the sealing shell 236 is communicated with the bottom of one side of the piston cylinder 231.

[0025] In this embodiment, when the upper tray 12 is stacked, it forms a push on the pressure plate 234. When the pressure plate 234 descends, it synchronously drives the piston rod 233 and the piston plate 232 to descend, and injects the air inside the piston cylinder 231 into the inside of the sealing shell 236 through the air pipe 2301. When the air enters the inside of the sealing shell 236, it pressurizes the inside of the sealing shell 236, forms a push on the rectangular plate 237, and pushes the top plate 239 upward.

[0026] In this embodiment, a plurality of second return springs 2302 are fixedly installed at the bottom of the rectangular plate 237. The bottom ends of the second return springs 2302 are fixedly connected to the bottom of the inner cavity of the sealing shell 236, which can facilitate the reset of the rectangular plate 237, so as to achieve the purpose of supporting and limiting when the upper tray 12 is stacked again.

[0027] In this embodiment, limiting strips 2303 are fixedly installed on both sides of the inner cavity of the sealing shell 236. The tops of the limiting strips 2303 are in contact with the bottom of the rectangular plate 237, which can limit the rectangular plate 237 when it descends, and avoid the situation that excessive descent affects the pressurization and rising. A limiting groove adapted to the upper tray 12 is opened at the bottom of the base 10, and the limiting groove is used to clamp the surface of the upper tray 12 during stacking.

[0028] When the utility model stacks the accessories, the upper tray 12 pushes the pressure plate 234 during stacking. When the pressure plate 234 descends, it synchronously drives the piston rod 233 and the piston plate 232 to descend, and injects the air inside the piston cylinder 231 into the inside of the sealed housing 236 through the air pipe 2301. When the air enters the inside of the sealed housing 236, it pressurizes the inside of the sealed housing 236, pushes the rectangular plate 237, and pushes the top plate 239 upward; when the upper tray 12 is separated from the lower tray 11, the rectangular plate 237 drives the limit strip 2303 to reset through the reset characteristic of the second return spring 2302, and reversely injects the gas inside the sealed housing 236 into the inside of the piston cylinder 231, so that the pressure plate 234 can be automatically reset, facilitating subsequent limiting during stacking.

[0029] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
