Description

Technical Field

[0001] The utility model relates to the technical field of storage cabinets, in particular to a sealed pull-out structure and a storage cabinet thereof. Background Art

[0002] The prior art discloses a pull-out server cabinet with a built-in sound insulation and sealing structure (CN202120378688.2), including a cabinet body, a pulley assembly is installed between the inner walls of the slot, which is convenient for taking out the internal server separately for maintenance and replacement, and a plurality of placement slots are provided, which can effectively avoid the phenomenon that the server spacing is too small and the heat is difficult to dissipate. A melamine board is bonded between the inner walls of the fiberboard, and the fiberboard can isolate the internal noise and optimize the working environment. The melamine board has good moisture absorption and ensures the dryness of the air in the cabinet. A hollow groove is arranged between the inner walls of the arc-shaped rubber pad, and negative pressure holes are evenly opened on the upper end of the arc-shaped rubber pad. Sealing rings are bonded to the outer walls around the isolation plate. When the drawer is pushed, the sealing ring can be squeezed with the arc-shaped rubber pad, and the negative pressure hole discharges the air inside the hollow groove, so that a pressure difference is formed between the hollow groove and the outside world. When the negative pressure hole fits with the sealing ring, the pressure difference can enhance the sealing and tightness to prevent the entry of external dust.

[0003] The existing technology achieves sealing between the drawer and the cabinet by using an elastic rubber strip to press against the wall of the drawer. The rubber strip has limited deformation capacity itself and is completely dependent on the rubber strip material. As the rubber strip continues to come into contact and wear with the drawer, a gap will form between the rubber strip and the drawer, and the sealing performance will be attenuated, leaving room for optimization.

[0004] To this end, we propose a sealed drawer structure and a storage cabinet thereof. Utility Model Content

[0025] like Figure 2 As shown, the retaining edge 21 is integrally formed with the rubber strip 10, and the retaining edge 21 is fixedly installed on the outer wall surface of the rubber strip 10. The retaining edge 21 surrounds the outer wall of the rubber strip 10 to form a closed loop. The groove 22 is opened on the back side of the retaining edge 21, and the groove 22 forms a rectangular groove. The groove 22 is opened at an angle, and circular holes for mounting holes are opened at the four corners of the retaining edge 21. By setting the integrally formed retaining edge 21, the contact body 20 and the retaining edge 21 are both made of rubber. By applying glue on the back side of the retaining edge 21, it is convenient to fix the retaining edge 21 to the cabinet.
