Abstract

The invention discloses a dustproof and waterproof device for ventilating holes of an outdoor box body, which comprises a casing, the casing includes a bridging plate, two side plates located on both sides of the bridging plate and connected through the bridging plate, and the two side plates are connected to the rear of the bridging plate The end plate with closed end is characterized in that the front end of the shell is fastened with a shell seat, and the shell seat is provided with a communication hole for communicating with the ventilation hole, and the communication hole and the cavity between the shell and the shell seat together form a direction The lower ventilation passage, the shell seat is provided with a dust-proof net for closing the communication hole. In the present invention, a cavity is formed between the shell seat and the shell, which increases the ventilation area and achieves a good ventilation effect. The shell and the outer wall of the box There is a shell seat between them, which makes the fixing structure more firm. At the same time, the dust-proof net is fixed on the shell seat, which also makes the installation of the dust-proof net more firm, thereby prolonging the service life of the dust-proof and waterproof device for the vent hole. The invention can be used universally. For the protection of the ventilation holes of the outdoor box.

Description

technical field [0001] The invention relates to a dust-proof and waterproof device for ventilation holes of an outdoor box, in particular to a protective device at the ventilation holes of electrical system boxes such as a control cabinet, a distribution box, and a mechanism box. Background technique [0002] When the electrical system box is in use, if there is no requirement for forced ventilation, ventilation holes are generally used for heat dissipation and ventilation. There will be rainwater entering the box from the ventilation holes, which will bring safety hazards to the reliable operation of the equipment in the box. Therefore, the ventilation holes are the key protection objects. The national standard stipulates that the protection level of the above-mentioned boxes must reach IP54, so the protection of the ventilation holes The protection level of the device also needs to meet the national standard of IP54. [0003] At present, the usual method for dust preventi...
