Problems solved by technology

At present, the treatment of the operation hole in the domestic ring network cabinet equipment adopts the pull plate or flip-type sealing device. The pull-plate type plugging structure has poor stability and cannot meet the protection level requirements. The flip type needs to be installed outside the equipment operation hole, which is easy to damage and cause damage. Seriously affect the integrity of the appearance of the ring network cabinet equipment

Abstract

The invention relates to a rotatable operation hole plugging device. The device is characterized in that the device comprises a rotating base (1), a rotating wheel (2) and a plurality of blades (3). The rotating base (1) is fixed to the cabinet body panel. Each end part of the blade (3) is rotationally connected with the rotating base (1). U-shaped grooves (21) that corresponding to the number ofblades (3) is arranged on the rotating wheel (2). Each blade (3) is connected with the rotating wheel (2) via an application (4) inserted in the corresponding U-shaped grooves (21), and the application (4) is capable of sliding in the U-shaped grooves (21). When the rotating wheel (2) rotates, a plurality of blades (3) are integrally closed and opened by the sliding of the application (4) connected thereto in the corresponding U-shaped grooves (21). According to the rotatable operation hole plugging device, the operation safety of the ring network cabinet equipment is improved, and equipment damage caused by operation errors is prevented.

Description

technical field [0001] The invention relates to the technical field of ring network cabinet equipment, in particular to a rotatable operation hole sealing device. Background technique [0002] Usually, the ring network cabinet equipment mainly includes a secondary instrument room, an air box room, a mechanism room and a cable room. The panel of the mechanism room is provided with operation holes for operating equipment. When this kind of equipment is in operation, on the one hand, to prevent non-designated operators from mishandling the equipment, and on the other hand, to prevent dust or rainwater from entering the equipment through the operation hole and affecting the operation reliability and service life, a blocking device is installed, and can Lock the operating hole with a padlock. At present, the treatment of the operation hole in the domestic ring network cabinet equipment adopts the pull plate or flip-type sealing device. The pull-plate type plugging structure has ...
