Described folder frame is provided with installing hole, and is provided with the chucking pillar on the described fixed pedestal accordingly, and described filter screen main body tightens fixing being installed on the fixed pedestal by the chucking pillar in installing hole.
In use, dustproof ventilation unit is installed on the ventilating opening of low voltage frequency converter and gets final product.
The practical dustproof ventilation unit of low voltage frequency converter provided by the invention has the following advantages:
1, the dustproof ventilation unit of described low voltage frequency converter can prevent willow catkins flying in the air, spun yarn and dust access arrangement air channel;
2, the dustproof ventilation unit dismounting of described low voltage frequency converter is all very convenient, and can also carry out dismounting under the situation of not closing low voltage frequency converter;
3, the dustproof ventilation unit of described low voltage frequency converter is an absolute construction, after slave unit is pulled down, does not influence the normal use of equipment and attractive in appearance.

Fig. 2 is the decomposing schematic representation of each building block of filter screen main body.
Fig. 3 has shown that the filter screen main body is installed on the concrete mode of fixed pedestal.
Fig. 4 is installed on the schematic diagram of low voltage frequency converter air inlet for dust cleaning apparatus.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail with specific embodiment.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
As illustrated in fig. 1 and 2, the dustproof ventilation unit that is used for low voltage frequency converter of the present utility model comprises filter screen main body 10 and fixed pedestal 20, and described filter screen main body 10 is installed on the fixed pedestal 20; Described filter screen main body 10 comprises filter screen 11, fixedly the filter screen fixed frame 12 of filter screen 11 and the folder frame 13,14 of both sides, and fixedly filter screen 11 and filter screen fixed frame 12 are fixedly clamped from both sides with described two folder frames 13,14 by fixture 30.
Preferably, described filter screen 11 is an air conditioner filter screen; Described fixture 30 is a fixed screw, certainly, also can select other suitable fixture for use.
As shown in Figure 2, the position of described fixed screw 30 geometrical clamp frames 13,14 is the both sides up and down at folder frame 13,14.As seen from the figure, each side of the both sides up and down of folder frame 13,14 is equipped with three screws 131,141, and the screw lock that is used for fixing screw 30 is fixed, and described three screws 131 lay respectively at both sides and position intermediate.
Fig. 3 has shown that filter screen main body 10 is installed on the mode of fixed pedestal 20, as shown in Figure 3A, is provided with installing hole 132,142 in addition on the folder frame 13,14, and this installing hole 132,142 roughly is Pear-Shaped, and a lateral aperture is bigger, and the opposite side aperture is less; Shown in Fig. 3 B-Fig. 3 D, fixed pedestal 20 is provided with corresponding chucking pillar 201, chucking pillar 201 is aimed at the place, large aperture of the installing hole 132,142 by will pressing from both sides frame 13,14, promote filter screen main body 10 then, chucking pillar 201 is tightened in the aperture of installing hole 132,142 smaller part, thereby filter screen main body 10 is installed on the fixed pedestal 20, constitutes dustproof ventilation unit of the present utility model.
