The purpose of the utility model is to provide outdoor case ventilation hole dustproof and waterproof device, and is not enough with the degree of protection that solves ventilation hole protector in the prior art, assemble insecure, the problem that ventilation effect is bad.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: outdoor case ventilation hole dustproof and waterproof device; Comprise shell, the biside plate that said shell comprises bridging board, is positioned at the bridging board both sides and links to each other through bridging board reaches the end plate with biside plate and bridging board back-end closure; Shell front end spiral-lock has shell block; Said shell block is provided with and is used for the intercommunicating pore that is communicated with ventilation hole, and the cavity between intercommunicating pore and shell and the shell block has constituted downward vent passages jointly, and shell block is provided with the Air Filter that is used for the intercommunicating pore sealing.
Vent passages bottom between shell and the shell block is provided with water-retaining structure.
Described water-retaining structure comprises the staggered outstanding water fender of establishing; A two adjacent water fenders end face separately is installed in respectively on the sidewall of each self-corresponding shell; The overhang center of shell of the other end, the both sides of water fender extend to respectively on the medial surface of end plate of shell block rear end face and shell.
Said water fender free end is in the downward-sloping angle of horizontal plane.
Convex with in the below of water fender on the said shell block rear end face and be used for the support raised line that cooperates with the water fender side lap, the medial surface of the opposite side of water fender and the end plate of shell fixedly installs.
Said bridging board is semicircle.
Convex with at least two on the medial surface of the end plate of shell and be used for shell and shell block are fixed on mounting boss on the casing, the position of the corresponding said mounting boss of shell block is provided with the assembling through hole.
The shell block front end face is provided with groove in assembling through hole peripheral ring, is provided with the gap sealed waterproof grommet that is used between shell block and the casing in the groove.
Said shell block front end face convexes with the preceding ring platform that is used to be inserted in the casing ventilation hole in the intercommunicating pore place; The endoporus front end of preceding ring platform is provided with Turbogrid plates; The shell block rear end face convexes with the back ring platform of internal diameter and intercommunicating pore equal diameters in the intercommunicating pore place; Said back ring platform inner chamber and intercommunicating pore have constituted the cavity that holds Air Filter jointly, and Air Filter is arranged in the said cavity.
The outer edge surface of the front end edge shell of shell convexes with eaves, and shell block has and is used for and the spacing outer edge surface that cooperates of the inner edge surface of said eaves, and the shell block buckle is in the eaves of shell.
The outdoor case ventilation hole dustproof and waterproof device of the utility model forms cavity between shell block and the shell, has increased draught area, reaches good ventilation effect.Shell is fixed on the cabinet exterior through shell block, makes fixed structure more firm, and Air Filter is installed on the shell block simultaneously, also makes the more firm of Air Filter installation, thereby prolongs the useful life of ventilation hole dustproof and waterproof device.
Further, the top of being arranged to that shell and shell block mate each other is semicircular structure, does not accumulate rainwater in the time of can guaranteeing to rain.
Further, the seal of shell block front end face setting does not need to be coated with fluid sealant around the shell in the prior art, prevents rainwater from connecting the casing of entering between the slit, and seal is arranged on shell block inside, is difficult for wearing out, and has prolonged the useful life of ventilation hole dustproof and waterproof device.
Further; The shell block front end face is provided with the preceding ring platform of protrusion; Before the ring platform cooperates with the ventilation hole sleeve, better with the vent of ventilation hole dustproof and waterproof device location and installation at casing, simultaneously Turbogrid plates also with Air Filter accurately be positioned at intercommunicating pore with after encircle in the inner chamber of platform.
Further, the outstanding interlaced water fender of establishing of outer casing underpart under the situation that does not increase the distance between shell lower ending opening and the ventilation hole, has prevented that effectively rainwater is splashed in the casing by vent passages.
Further, the downward-sloping angle of water fender free end, when effectively having prevented to dabble, aqueous reflux advances vent passages.
