[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A portable display cabinet comprises a box body 1, a glass cover 2 is fixed on the top surface of the box body 1, an opening is opened on the top surface of the box body 1, and the glass cover 2 is arranged opposite to the opening. It is characterized in that a cylinder 3 is installed on the inner bottom surface of the box body 1, and a lifting plate 4 is fixed on the telescopic end of the cylinder 3, and the lifting plate 4 extends into the opening.

[0021] A sealing assembly is provided between the opening and the lifting plate 4, and the sealing assembly includes an annular groove 51, an annular sealing bag 52 and two sealing frames 53. The annular groove 51 is provided on the inner surface of the opening, and the annular sealing bag 52 is bonded to the groove wall of the annular groove 51. The two sealing frames 53 are fixedly sleeved on the lifting plate 4, and the two sealing frames 53 are arranged vertically opposite to each other. When the annular sealing bag 52 expands, it can extend between the two sealing frames 53 and press the lifting plate 4. At this time, the annular sealing bag 52 and the two sealing frames 53 can form a staggered sealing structure, thereby improving the sealing performance between the lifting plate 4 and the opening.

[0022] The box 1 is provided with an inflatable assembly, which includes a sealing cylinder 61, a sliding plug 62, a connecting rod 63, a spring 64 and an air pipe 65. The sealing cylinder 61 is fixed to the inner surface of the box 1. The sealing cylinder 61 is arranged at the bottom of the inner surface of the box 1, which is convenient for the staff to step on the elbow part of the connecting rod 63 with their feet without manual operation. The sliding plug 62 is sealingly slidably connected to the inner surface of the sealing cylinder 61. One end of the connecting rod 63 is fixedly connected to the sliding plug 62, and the other end extends to the outside of the sealing cylinder 61. One end of the connecting rod 63 located outside the sealing tube 61 is provided with an elbow, one end of the spring 64 is connected to the inner surface of the sealing tube 61, and the other end is connected to the sliding plug 62, one end of the air pipe 65 is connected to the sealing tube 61, and the other end is connected to the annular sealing bag 52. Under the elastic force of the spring 64, the sliding plug 62 always has a tendency to move, that is, the sliding plug 62 always has a tendency to press the gas into the inside of the annular sealing bag 52, which makes the annular sealing bag 52 always in an inflated state.

[0023] The specific working principle of the utility model is as follows:

[0024] When the portable display cabinet proposed by the utility model is in use, the staff first places the exhibits on the lifting plate 4. After placing the exhibits, the staff pulls the connecting rod 63 downward. When the connecting rod 63 moves downward, it can drive the sliding plug 62 to move downward. When the sliding plug 62 moves downward, it can perform a pumping action and pump the gas inside the annular sealing bag 52 into the interior of the sealing tube 61 through the air pipe 65, which makes the annular sealing bag 52 shrink and completely retract into the interior of the annular groove 51. Then the staff starts the cylinder 3, so that the cylinder 3 drives the lifting plate 4 to move upward until the lifting plate 4 moves into the opening. At this time, the two sealing frames 53 on the lifting plate 4 are just arranged opposite to the annular groove 51. Further, the staff loosens the connecting rod 63, so that the sliding plug 62 is reset under the action of the spring 64. When the sliding plug 62 is reset, the gas can be pressed into the sealing tube through the air pipe 65 again. The inside of the annular sealing bag 52 is inflated and expanded. When the annular sealing bag 52 is expanded, it can extend between the two sealing frames 53 and press the lifting plate 4. At this time, the annular sealing bag 52 and the two sealing frames 53 can form a staggered sealing structure, thereby improving the sealing performance between the lifting plate 4 and the opening. In addition, under the elastic force of the spring 64, the sliding plug 62 always has a tendency to move, that is, the sliding plug 62 always has a tendency to press the gas into the inside of the annular sealing bag 52, which makes the annular sealing bag 52 always in an inflated state. When the annular sealing bag 52 is aged and deformed, the inflation action can timely compensate for the deformation caused by the aging of the annular sealing bag 52, so that the annular sealing bag 52 can always fit closely with the lifting plate 4. This design can further ensure the sealing performance between the lifting plate 4 and the opening.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
