Description

Technical Field

[0001] The utility model relates to a nitrogen type moisture-proof cabinet. Background Art

[0002] A nitrogen moisture-proof cabinet is a cabinet that uses nitrogen to achieve the purpose of moisture-proof and anti-oxidation, and is used to store precision electronic components, special chemical drugs and other items, and is widely used in the field of item storage.

[0003] The existing nitrogen moisture-proof cabinet is provided with several cells for facilitating the classified storage of items, and the nitrogen moisture-proof cabinet is connected with a nitrogen supply pipe; when storing items in one or several cells, the nitrogen supply pipe can only convey nitrogen to the whole nitrogen moisture-proof cabinet, and cannot convey nitrogen to the cells where the items are stored separately, resulting in waste of nitrogen resources. Summary of the Invention

[0004] The purpose of the utility model is to provide a nitrogen type moisture-proof cabinet, which includes a cabinet body and a nitrogen supply pipe. A plurality of cells are arranged inside the cabinet body. Air holes are opened on the rear plates of each cell, and sealing flip covers are arranged on the air holes. A pull-out tray is movably arranged in each cell. A thimble is arranged on the surface of the pull-out tray close to the air hole, and the thimble can push open the sealing flip cover. The nitrogen supply pipe is connected to the air hole.

[0005] Preferably, the sealing flip cover includes a hinge seat, a cover plate and a sealing layer. The hinge seat is arranged at the outer top of the air hole. The cover plate is movably connected in the hinge seat, and the sealing layer is arranged on the contact surface between the cover plate and the air hole.

[0006] Preferably, guide rail grooves are opened in the cells along the pulling direction of the pull-out tray. The ends of the guide rail grooves facing the opening direction of the cells are open ends, and corresponding guide blocks are arranged on the pull-out tray. The guide blocks are slidably arranged in the guide rail grooves.

[0007] Preferably, a door panel is arranged at the outer end of the pull-out tray, and the door panel is adapted to the opening of the cell.

[0008] Preferably, a handle is arranged on the outer side surface of the door panel.

[0009] The advantages and beneficial effects of the utility model are as follows: by installing the pull-out tray with items into the cell, the thimble on the pull-out tray pushes open the sealing flip cover to open the air hole, and the nitrogen supply pipe conveys nitrogen to the cell, so that the nitrogen type moisture-proof cabinet of the utility model can convey nitrogen to the cell where the items are stored separately, avoiding waste of nitrogen resources. Description of the Drawings

[0010] Figure 1It is a schematic diagram of the present utility model. Detailed implementation manners

[0011] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0012] The technical solution specifically implemented by the present utility model is as follows:

[0013] As Figure 1 shown, a nitrogen-type moisture-proof cabinet includes a cabinet body 1 and a nitrogen supply pipe 2. A plurality of cells 3 are arranged inside the cabinet body 1. Air holes 4 are opened on the rear plates of each cell 3. A sealing flap 5 is provided on the air holes 4. A pull-out tray 6 is movably arranged in each cell 3. A thimble 7 is provided on the surface of the pull-out tray 6 close to the air hole 4. The thimble 7 can push open the sealing flap 5. The nitrogen supply pipe 2 is connected to the air hole 4.

[0014] The above-mentioned sealing flap 5 includes a hinge seat 51, a cover plate 52 and a sealing layer 53. The hinge seat 51 is arranged at the outer top of the air hole 4. The cover plate 52 is movably connected inside the hinge seat 51. The sealing layer 53 is provided on the contact surface of the cover plate 52 and the air hole 4. During actual use, when the thimble 7 pushes up the cover plate 52, the cover plate 52 turns upward with the hinge seat 51 as the center point, opening the air hole 4. When the thimble 7 separates from the cover plate 52, the cover plate 52 drops due to gravity, covering the air hole 4. And due to the air pressure of the nitrogen supply pipe 2, the sealing layer 53 of the cover plate 52 is pressed on the air hole 4, forming the closure of the air hole 4.

[0015] A guide rail groove 8 is opened in the cell 3 along the pulling direction of the pull-out tray 6. The end of the guide rail groove 8 facing the opening direction of the cell 3 is an open end. A corresponding guide block 9 is provided on the pull-out tray 6. The guide block 9 is slidably arranged in the guide rail groove 8. During actual use, the guide block 9 slides in the guide rail groove 8, making the pulling movement of the pull-out tray 6 in the cell 3 more stable.

[0016] A door panel 10 is provided at the outer end of the pull-out tray 6. The door panel 10 is adapted to the opening of the cell 3.

[0017] A handle 11 is provided on the outer side surface of the door panel 10. During actual use, it is convenient to pull the pull-out tray 6 in the cell 3.

[0018] When in use, place the item on a drawer tray 6, and then install the drawer tray 6 into one of the cells 3 of the cabinet body 1. The guiding block 9 of the drawer tray 6 moves along the guide rail groove 8 of the cell 3. When the ejector pin 7 of the drawer tray 6 pushes the cover plate 52 of the sealing flap 5 upwards to open the air hole 7 of the cell 3, the nitrogen supply pipe 2 conveys nitrogen to the cell 3. Thus, a nitrogen-type moisture-proof cabinet of the present utility model can separately supply gas to the cell 3 for storing items, avoiding waste of nitrogen resources.

[0019] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
