Embodiment Construction
[0024] Such as Figure 1 to Figure 5 As shown, an embodiment of a dust-proof ventilation device for a cabinet, the dust-proof ventilation device in this embodiment includes a cabinet body 102, and a plurality of ventilation holes 110 are evenly distributed on the cabinet body 102, and the ventilation holes 110 are all circular hole structures. The cabinet body 102 here is a sheet metal structure, and a grille 101 is fixedly arranged on the inner side wall of the cabinet body 102 corresponding to the position of the plurality of ventilation holes. Composed of waterproof grille blades 107, the peripheral frame 106 corresponds to the area where the ventilation holes are distributed. Here, the waterproof grille blades 107 are arranged at intervals along the up and down direction, and the waterproof grille blades 107 are arranged obliquely in parallel with each other. The waterproof grille blades 107 are inclined at 60°. In this embodiment, the circumferential frame 106 is seamless...

The invention relates to a dustproof ventilation device for a machine cabinet and the machine cabinet with the dustproof ventilation device. The dustproof ventilation device for the machine cabinet comprises a cabinet body provided with a plurality of ventilation holes; a circumferential surrounding frame is arranged at the positions, corresponding to the through holes, of the inner side wall of the cabinet body, and a plurality of waterproof grating blades are all sequentially arranged in the circumferential surrounding frame in the vertical direction at intervals and are obliquely arranged in parallel; the circumferential surrounding frame is provided with an opening part deviating from the ventilation holes, and a filter screen is fixed to the opening part of the circumferential surrounding frame in a press fitting mode through a filter screen pressing frame; one side of the filter screen pressing frame is correspondingly assembled to the circumferential surrounding frame in a hinged manner around a hinged shaft; a detachable fixed connection structure is arranged between the filter screen pressing frame and the circumferential surrounding frame. In use, when the filter screen needs to be replaced and cleaned, the detachable fixed connection structure is opened, the filter screen pressing frame rotates reversely around the hinged shaft to get away from a fixed pressing frame, then the filter screen can be replaced, replacement, assembly and disassembly are all convenient, and operation is easy.
Description
technical field [0001] The invention relates to a dust-proof ventilation device for a cabinet and a cabinet using the dust-proof ventilation device. Background technique [0002] With the development of society, the environmental requirements of power supporting facilities continue to increase. In order to meet the use of electrical cabinets in harsh environments and protect the normal use of internal electrical components, it is necessary to increase the IP rating of the cabinet. Especially for structures that require heat dissipation, improving the protection level at the ventilation holes is of great significance to the improvement of the overall protection level of the cabinet. Most of the existing ventilation and heat dissipation structures are stamped louver structures on the cabinet body, and then add a cover box, but this general ventilation structure does not meet the requirements of a higher protection level at all, and the waterproof effect is poor. Moreover, due...
