With reference to figure 1~4 and Fig. 9, place, bottom in front door 106 is formed with air inlet 113, place, top in this left plate 102 and right plate 103 is formed with blower fan opening 114, this blower fan opening 114 places are provided with a blower fan 115, this blower fan 115 is covered with a fan shroud 116, and the air outlet 117 of this fan shroud 116 is formed at the lower surface of this fan shroud 116.So, be arranged at the side place of this rack 10 due to blower fan 115, and air outlet 117 is formed at fan shroud 116, can prevents effectively that rainwater from entering rack 10 inside from air outlet 117 places, to strengthen the water resistance of rack 10.Preferably, 113 places are provided with discharge filter in this air inlet, and add protective plate 118 in this air outlet 117 places.By the setting of this discharge filter, can prevent that the foreign matter such as dust is along with air flows into this rack 10 inside from this air inlet 113, particularly in electronic device works; And by the setting of this protective plate 118, can prevent that the foreign matters such as dust from wafing into this rack 10 inside from this air outlet 117, particularly when electronic equipment is out-of-work.
In the embodiment shown in the figures, place, bottom in each front door 106 all is formed with air inlet 113, and all be formed with blower fan opening 114 in place, the top of this left plate 102 and right plate 103, and in each blower fan opening 114 places, blower fan 115 and fan shroud 116 are set, certainly, can be according to the actual needs only form air inlet 113 on a front door 106, perhaps only form blower fan opening 114 in left plate 102 and right plate 103 on the one in both.
In conjunction with shown in Figure 10, be formed with one the 3rd capillary groove 119, the three capillary grooves 119 in the lateral surface place of each blower fan opening 114 and arrange along the edge of this blower fan opening 114, and its notch be towards the surrounding outside of this blower fan opening 114.Ideally, the 3rd capillary groove 119 also is designed to the structure that the cross section takes the shape of the letter U.So, the ponding that can be by the 3rd capillary groove 119 blower fan opening 114 places be produced be guided to the place, ground, avoids it to infiltrate rack 10 inside, thereby promotes the degree of protection of rack 10.
Preferably, in conjunction with shown in Figure 11, lateral surface place in the 3rd capillary groove 119 is provided with one the 3rd sealing joint strip 120, like this, setting by the 3rd sealing joint strip 120, play the effect of cooperation place between sealing air hood and blower fan opening 114, can prevent from entering from both cooperation places such as rainwater rack 10 inside, thereby improve the degree of protection of rack 10.
This base plate 101, left plate 102, right plate 103 and lamina tecti 105 are the full weld structure with the overlap edge exposed section of this framework 100 separately, namely adopt the full weld welding manner with base plate 101, left plate 102, right plate 103 and lamina tecti 105 respectively welding assemblies on this framework 100.Like this, can guarantee that the overlap edge place of base plate 101, left plate 102, right plate 103 and lamina tecti 105 and this framework 100 is water-tight, and improve the water resistance of rack 10.
Consult Figure 12 and Figure 13, be provided with a waterproof form 121 on this front door 106, this waterproof form 121 includes a window opening 122, that is formed on this front door 106 and is positioned at the press box 124 that the inboard transparent panel 123 and of locating and cover this window opening 122 of this window opening 122 is fixed this transparent panel 123.Like this, setting by this waterproof form 121, within the supervisory keyboard 20 ' (see figure 1) of electronic equipment can being arranged at this rack 10, demonstration situation by these waterproof form 121 observation supervisory keyboards 20 ', and need not to offer for the keyboard installation position that supervisory keyboard is installed at front door 106, avoid occurring rainwater from the situation of infiltration rack 10 inside, keyboard installation position, promoted the degree of protection of rack 10.
Adopt the frequency converter of the rack 10 of said structure, supervisory keyboard can be arranged within this rack 10 corresponding to this waterproof form 121 places, reason as above can promote the degree of protection of frequency converter.
Consult Figure 12, be provided with an escutcheon 125 corresponding to this waterproof form 121 places on these front door 106 lateral surfaces, to play the effect of decorative waterproof water form 121, improve its aesthetics.
Consult Fig. 1 and Fig. 2, respectively be embedded with a nut 126 in four corners of the lamina tecti 105 of this rack 10, be screwed with suspension ring 127 on each nut 126, like this, can electronic equipment be hung by four suspension ring 127 and be installed on target location.In conjunction with Figure 14 and Figure 15, the lower end of this nut 126 is formed with a sealing surface 128, and this nut 126 welds with the junction full weld of lamina tecti 105.Like this, when electronic apparatus application during in outdoor environment, even rainwater enters nut 126 inside along suspension ring 127, also be unlikely to infiltrate rack 10 inside, reach the requirement of high-grade protection.
In sum, rack disclosed in the utility model adopts above-mentioned various safeguard structures, can significantly promote the degree of protection of the electronic equipment (for example frequency converter) that uses this type of rack, make electronic equipment can directly apply to outdoor environment such as place, harbour etc.
The above is only preferred embodiment of the present utility model, but not the utility model is done any pro forma restriction.Those skilled in the art can impose the various changes that are equal to and improvement on the basis of above-described embodiment, all equivalent variations of doing in the claim scope or modification are within all should falling into protection range of the present utility model.
