Technical Field
[0001] The utility model relates to the technical field of pneumatic drawer cabinets, in particular to a pneumatic drawer cabinet. Background Art
[0002] A pull-out cabinet is a common rectangular storage furniture, which is mainly composed of a cabinet body and a pull-out part. The cabinet body serves as the basic structure, with side panels around it, a bottom panel at the bottom, a top panel at the top and a back panel on the back. These panels are made of various materials, including wood, artificial panels and metal materials.

The pull-out shelf is slidably connected to the cabinet body to switch between the first state and the second state. During the sliding process of the pull-out shelf, the limit assembly abuts against the top side of the pull-out shelf to limit the pull-out shelf from rotating in the direction along the pull-out end toward the bottom side. The limit assembly includes a first limit member and a second limit member located between the first limit member and the pull-out opening. When the pull-out shelf is in the first state, the limit assembly abuts against the top side of the pull-out shelf to limit the pull-out shelf from rotating in the direction along the pull-out end toward the bottom side. When the shelf is in the second state, the second limit member abuts against the pull-out shelf to limit the pull-out shelf from sliding toward the side away from the accommodating cavity. When the avoidance opening is located on the bottom side of the second limit member, the first limit member abuts against the end of the pull-out shelf away from the pull-out end to avoid the pull-out shelf from rotating along the pull-out end toward the top side. The pull-out cabinet of this application embodiment can prevent tipping over, while the existing pull-out cabinet relies on manual pulleys and springs to achieve reset. However, the manual pulleys and springs will age after long-term use, resulting in problems such as pulley deformation and noise and spring aging and loss of elasticity. Utility Model Content

This pneumatic reset method only needs to replenish the air pressure in the micro-cylinder 3 when the state declines due to a long time. This achieves the effect of avoiding the aging of manual pulleys and springs during long-term use, and at the same time prolongs the service life of the drawer cabinet.
[0046] If the air pressure in the micro cylinder 3 needs to be supplemented or adjusted during the use of the pneumatic pull-out cabinet, first rotate the pull ring 206 to drive the rotation of the dust plug 205, and adjust the buckle 204 to the position corresponding to the slot 202 through the rotation of the dust plug 205, and then pull the pull ring 206 to pull the dust plug 205 out of the pressure regulating slot 203; then use the pressure regulating valve 201 behind the micro cylinder 3 to adjust or supplement the internal air pressure. After the operation is completed, the dust plug 205 can be put back in place, thereby achieving the effect of convenient adjustment and supplement of the air pressure in the micro cylinder 3.
