[0008] The sealing cover is fixedly connected to a mounting groove, an inner insert tube is fixedly connected to the inner side of the mounting groove, the inner insert tube is slidably connected to the inner wall of the fresh-keeping box, an outer insert tube is fixedly connected to the outer side of the mounting groove, the outer insert tube is slidably connected to the outer wall of the sealing insert tube, a sealing ring is installed in the mounting groove, the sealing ring and the sealing insert tube cooperate with each other, an elastic drum piece is fixedly connected to the sealing cover, and a handle is rotatably connected to the elastic drum piece.

[0009] As a further solution of the present invention: a support block is fixedly connected to the bottom of the fresh-keeping box.

[0010] As a further solution of the present invention: a vent hole is provided in the sealing cover, a rubber sealing plug is installed in the vent hole, and the rubber sealing plug is fixedly connected to the sealing cover.

[0011] Compared with the existing technology, the beneficial effect of the present invention is that the present invention controls the pressure inside the fresh-keeping box by arranging an elastic drum piece with freely changeable bulge direction in the sealing cover of the fresh-keeping box, thereby sealing the fresh-keeping box and the sealing cover through the air pressure difference. No snaps are required, and the installation and opening are convenient and quick, which improves the practicality of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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.

[0019] See Figures 1 to 5 In the embodiment of the utility model, a quick-release fresh-keeping box for a refrigerator includes a fresh-keeping box 1 and a sealing cover 5. A sealing port 2 is provided on the top of the fresh-keeping box 1, and a sealing insert 3 is fixedly connected to the sealing port 2. A mounting groove 6 is fixedly connected to the sealing cover 5, and an inner insert 8 is fixedly connected to the inner side of the mounting groove 6. The inner insert 8 is slidably connected to the inner wall of the fresh-keeping box 1, and an outer insert 7 is fixedly connected to the outer side of the mounting groove 6. The outer insert 7 is slidably connected to the outer wall of the sealing insert 3. A sealing ring 9 is installed in the mounting groove 6, and the sealing ring 9 cooperates with the sealing insert 3. An elastic drum piece 10 is fixedly connected to the sealing cover 5, and a handle 11 is rotatably connected to the elastic drum piece 10. A vent 12 is provided in the sealing cover 5, and a rubber sealing plug 13 is installed in the vent 12. The rubber sealing plug 13 is fixedly connected to the sealing cover 5.

[0020] The utility model first slides the sealing cover 5 and the fresh-keeping box 1 together through the sliding connection between the inner insert tube 8 and the inner wall of the fresh-keeping box 1, and during the insertion, the elastic drum piece 10 needs to be pressed down until it is recessed into the fresh-keeping box 1. At this time, the sealing insert tube 3 is inserted into the installation groove 6, and the outer insert tube 7 is inserted into the outside of the sealing opening 2, thereby protecting the outside of the sealing opening 2 and preventing debris from contaminating the sealing opening 2 of the fresh-keeping box 1. After that, the staff buckles the handle 11 and drives the handle 11 to pull up, thereby driving the elastic drum piece 10 to elastically swell to the side away from the fresh-keeping box 1. At this time, the effective space in the fresh-keeping box 1 is increased, the air pressure is reduced, and the inside and outside of the fresh-keeping box 1 are generated. The air pressure difference acts on the sealing cover 5, and the driving force generated by the air pressure difference pushes the sealing cover 5 to press the side of the fresh-keeping box 1, thereby achieving a tight closure between the sealing cover 5 and the fresh-keeping box 1, thereby preventing external air from entering the fresh-keeping box 1, and then sealing and preserving the fresh-keeping box 1. Later, when the fresh-keeping box 1 needs to be disassembled, it is only necessary to pull the rubber sealing plug 13 out of the vent 12. At this time, the vent 12 is opened, and external air enters the fresh-keeping box 1. The air pressure inside and outside the fresh-keeping box 1 is the same, and the sealing cover 5 is no longer under pressure. At this time, the sealing cover 5 can be directly pulled to pull the sealing cover 5 out of the fresh-keeping box 1, thereby achieving quick disassembly of the sealing cover 5.

[0021] In one embodiment of the present invention, see Figures 1 to 5 The bottom of the fresh-keeping box 1 is fixedly connected to a support block 4. The utility model supports and isolates the bottom of the fresh-keeping box 1 from the placement table through the setting of the support block 4, thereby preventing the bottom of the fresh-keeping box 1 from freezing on the inner wall of the refrigerator, affecting the normal taking and placing of the fresh-keeping box 1.

[0022] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and range of equivalents of the claims be included in the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
