Description
Technical field
The utility model relates to the outdoor communication rack, is specifically related to the dustproof filter air inlet structure of outdoor communication rack.
Background technology
In communications industry, the outdoor communication rack is common cabinet type.Outdoor communication rack inside all needs to circulate normal to guarantee rack internal work temperature with outside air.In circulation, a large amount of dust enter rack inside with air, cause dirt accumulation in the rack, may cause dust to stop up in the time of serious, equipment can not normally move, and brings huge inconvenience to later maintenance, so on the outdoor communication rack air inlet filtration need be set.
Existing outdoor communication rack all is directly to establish a shutter as air inlet in the bottom of sidewall or door-plate, is screwed one deck filter course is installed on this air inlet.Above-mentioned prior art has following weak point: the one, and air inlet directly is opened in sidewall or door-plate bottom, and dust is more in the air intake of collecting; The 2nd, existing air filtration structure is directly to be screwed one deck filter course is installed on air inlet, and this filter course is not easy to cleaning and changes.
Summary of the invention
The utility model provides a kind of dustproof air inlet structure of outdoor communication rack, to improve the air intake quality and to be convenient to cleaning filter net.
For achieving the above object, the technical solution adopted in the utility model is: a kind of dustproof air inlet structure of outdoor communication rack, by first order air inlet, second level air inlet, be communicated with cavity and dustproof guard composition in sidewall or the door-plate, described first order air inlet is opened in the top of the lamina rara externa of outdoor communication cabinet sidewalls or door-plate, second level air inlet is opened in the bottom of the inner plating of outdoor communication cabinet sidewalls or door-plate, be communicated with cavity in described sidewall or the door-plate and be outdoor communication cabinet sidewalls or door-plate in, cavity between the lamina rara externa, it is connected between first order air inlet and the second level air inlet; Described dustproof guard constitutes by covering filter course on the mesh base plate; Two relative edges of corresponding at least dustproof guard are along being provided with draw-in groove on the inboard periphery of described second level air inlet, and described dustproof guard is with edge and draw-in groove corresponding matching inlay card, thereby dustproof guard fixedly blocks second level air inlet.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described dustproof guard is a rectangular plate shape, and draw-in groove is established at three edges of corresponding dustproof guard on the inboard periphery of second level air inlet, constitutes " U " shape three checkpost groove structures.
2, in the such scheme, the filter course of described dustproof guard is two-layer, and wherein one deck is the stainless steel Air Filter, and another layer is a sponge.
The utility model design principle and effect are: the utility model utilizes the hollow double side walls or the door panel structure of outdoor communication mechanism, at the upper opening of its lamina rara externa as first order air inlet, and the lower openings of laminate is as second level air inlet within it, and the cavity in sidewall or door-plate is communicated with between the two; And on the air inlet of the second level so that the slot mode of dismounting fixing dustproof guard.During use, air intake enters through first order air inlet, goes to second level air inlet downwards in the cavity in sidewall or door-plate then, enters rack inside again after dustproof guard filters.So design, the one, the position of collecting folk songs in the rack outside is raised, the quality of air intake is improved; The 2nd, to flow through in the cavity of air intake in sidewall or door-plate, some dusts can filter down and drop in sidewall or the door-plate cavity; The 3rd, dustproof guard is an individual components, and it is fixed by the slot mode, and direct withdrawing goes out to get final product when needing replacing or cleaning, and is very convenient.
