DETAILED DESCRIPTION

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

[0023] See Figures 1 to 7 A storage box includes a box body 200 and a box cover 100. An exhaust hole 130 is provided at the center of the box cover 100. An exhaust channel 300 is installed in the exhaust hole 130. A one-way valve 312 is installed in the exhaust channel 300, so that the storage box can vacuum the inside of the box body 200 through a vacuum pumping device to preserve 3D printing materials.

[0024] The edge of the box cover 100 is provided with a first sealing ring 110 extending toward the box body 200, and the side of the box cover 100 facing the box body 200 is provided with a second sealing ring 120 extending toward the box body 200. The edge of the opening of the box body 200 is provided with a support ring 210, and the inner edge of the support ring 210 is provided with a third sealing ring 211 extending toward the box cover 100. When the box cover 100 covers the box body 200, the outer edge of the support ring 210 is embedded in the first sealing ring 110, and the third sealing ring 211 is embedded in the second sealing ring 120. At the same time, a snap-fit ​​structure 400 is provided between the box cover 100 and the box body 200. The snap-fit ​​structure 400 can make the box cover 100 fit together with the box body 200, thereby ensuring sealing performance.

[0025] The snap-fit ​​structure 400 includes a first connector 410 positioned on the box body 200 and a second connector 420 positioned on the box lid 100. The first connector 410 is mounted with a rotatable first stopper 430, which in turn is mounted with a rotatable second stopper 440. The second stopper 440 has a limiting opening. After the second connector 420 is introduced into the limiting opening, the first stopper 430 is rotated, causing the second stopper 440 to rotate and move downward, causing the limiting opening to press against the first connector 410, causing the first connector 410 to move toward the second connector 420, thereby securing the box lid 100 to the box body 200 and ensuring a tight seal. Specifically, the first connecting member 410 includes a first plate 411 extending from the box body 200. A second plate 412 is provided at the end of the first plate 411. The second plate 412 is perpendicular to the first plate 411. A plurality of first reinforcing plates 413 are provided between the first plate 411 and the second plate 412 to strengthen the connection strength between the first plate 411 and the second plate 412. A first mounting groove 414 is provided on the first reinforcing plate 413. The first limiting member 430 is provided with a first rotating shaft 431. The first rotating shaft 431 is rotatably embedded in the first mounting groove 414, thereby enabling the first limiting member 430 to rotate. The first limiting member 430 is also provided with a second mounting groove 432. The second limiting member 440 includes a second rotating shaft 441. The second rotating shaft 441 is rotatably embedded in the second mounting groove 432, thereby enabling the second limiting member 440 to rotate relative to the first limiting member 430. When the first limiting member 430 rotates, the position of the second rotating shaft 441 will be changed, thereby driving the second limiting member 440 to move. The rotation of the second limiting member 440 can make it buckle itself on the second connecting member 420. The downward rotation of the first limiting member 430 can drive the second limiting member 440 to move downward, thereby applying pressure to the box cover 100 and the box body 200 through the second limiting member 440.

[0026] A plurality of second reinforcing plates 121 connected to the box cover 100 are provided on the inner side of the second sealing ring 120. The second reinforcing plates 121 are triangular structures. The second reinforcing plates 121 can strengthen the connection strength between the second sealing ring 120 and the box cover 100, thereby preventing the second sealing ring 120 from breaking when the box cover 100 is opened.

[0027] The exhaust channel 300 includes a channel body 310, and a mounting cover 311 is provided on the upper part of the channel body 310. The box cover 100 is provided with a limiting ring 140 surrounding the exhaust hole 130. The mounting cover 311 is embedded in the limiting ring 140, which can further seal the exhaust hole 130 and further improve the overall sealing performance.

[0028] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
