Embodiment
The utility model provides a kind of ventilation top cover, to realize effective waterproof on the dustproof basis.
The basic thought that the utility model addresses the above problem is: be set to the separately design of base and cover plate by the ventilation top cover, and cover plate specifically comprise two-layer, ground floor cover plate and second layer cover plate; The opening of the U-lag body of second layer cover plate covers the slit of ground floor cover plate fully, makes that water droplet can be caught by the U-lag body of second layer cover plate and be unlikely to fall into rack internal damage electrical equipment when water droplet dropped on gap position on the ground floor cover plate.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the understructure schematic diagram that Fig. 1 provides for the utility model embodiment, Fig. 2 are the end view of Fig. 1, and Fig. 3 is the C-C cutaway view of Fig. 1, and Fig. 4 is the A partial enlarged drawing of Fig. 3.
Wherein 1 is base, and 11 is buckle, and 12 is slot cover, and 13 and 14 is projection.
See also, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the ventilation top cover assembling schematic diagram that Fig. 5 provides for the utility model embodiment, Fig. 6 is the B-B cutaway view of Fig. 5, Fig. 7 is the A partial enlarged drawing of Fig. 6, Fig. 8 is the C-C cutaway view of Fig. 5.
Wherein 1 is base, and 2 is cover plate, and 11 is buckle, and 12 and 13 is projection, is 21 for the ground floor cover plate, and 22 is second layer cover plate.
Further in order to make the water droplet that drops on the U-lag body skid off top cover rapidly, the U-lag body is set to certain angle or is set to arch.Because arch is that middle high both sides are low; Can be and be obliquely installed on one side high another side is low, also can be low for high both sides, centre, institute can be slipped to outside the top cover rapidly so that drop on the interior water droplet of U-lag body.U-lag body angle of inclination can set up on their own, because it is less to fall into the water yield of U-lag body inside, so usually the angle of inclination is set at 1 degree, the angle of inclination of 1 degree can not cause cover plate 2 too high because the angle of inclination is excessive so that water droplet is flowed out completely yet.
In sum, be set to the separately design of base and cover plate by the ventilation top cover among the utility model embodiment, and cover plate specifically comprise two-layer, ground floor cover plate and second layer cover plate; The opening of the U-lag body of second layer cover plate covers the slit of ground floor cover plate fully, make when water droplet drops on gap position on the ground floor cover plate, water droplet can be caught by the U-lag body of second layer cover plate and be unlikely to fall into rack internal damage electrical equipment, and the water droplet that drops in the U-lag body can be slipped to outside the top cover rapidly.
Further in order better to guide the water that drops on the ventilation top cover better to flow in the U-lag body of second layer cover plate 22, described ground floor cover plate 21 also is made up of a plurality of U-lag bodies, Open Side Down for the U-lag body of ground floor cover plate 21, and U-lag body two sides are to the cell body outer inclination, be provided with the slit between per two U-lag bodies of ground floor cover plate 21, the opening of the U-lag body of second layer cover plate 22 covers the slit between 21 two U-lag bodies of ground floor cover plate fully, and the opening of the U-lag body of ground floor cover plate 21 covers the slit between 22 two U-lag bodies of second layer cover plate fully.
In sum, structure by ground floor cover plate 21 also being designed to form in the present embodiment by a plurality of U-lag bodies, and U-lag body two sides are to the cell body outer inclination, make the water on the U-lag body that drops on ground floor cover plate 21 flow into the U-lag body inside of second layer cover plate 22 along the side that tilts.
Described buckle 11 passes the slit between corresponding two U-lag bodies of second layer cover plate 22, blocks described two U-lag bodies.The material of the ventilation top cover that the utility model embodiment provides is an acrylonitrile-butadiene-styrene copolymer.
In sum, the utility model uses buckle that cover plate is installed on the base, and is easy for installation, only needs request by cover plate being installed on the base; Material of the present utility model is an acrylonitrile-butadiene-styrene copolymer, and good looking appearance is generous, and has solved the top cover problem on deformation that causes in the cabinet transportation.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
