This embodiment has set up 2 groups of filter screen subassemblies 9 in whole ventilation window region, and its external dimension is 3mm little about than the internal dimension of ventilation window after closing, controls little 3mm, during the installation, strengthens ventilation board R angle 22 and all outwards installs, and concrete installation flow is as follows:
the outer side 14 of the beam is grounded, 2 groups of filter screen assemblies 9 are attached back to back, the set bending dead edges face outwards and are placed between the U-shaped beam 1 and the positioning pin assembly 4, the 2 groups of filter screen assemblies 4 are held by one hand, the U-shaped left and right movable upright posts 3 are rotated by the other hand, when the U-shaped left and right movable upright posts 3 are rotated to a certain angle, the inner sides of the U-shaped left and right movable upright posts 3 are pressed into the R angle 22 of the reinforced ventilating plate, the friction resistance in the initial stage is small under the action of the R angle, the U-shaped left and right movable upright posts are gradually pressed in the same time, the positioning pin assemblies 4 positioned on the inner sides of the U-shaped left and right movable upright posts 3 are also pressed into the R angle 22 of the other reinforced ventilating plate to be attached, and the friction resistance is small at the initial stage; the U-shaped movable upright post 3 is pushed to the bottom, the structure form of the U-shaped bending piece is adopted on the periphery, and after the horizontal plane is contacted with the vertical plane, the angle is limited to 90 degrees, namely the U-shaped movable upright post 3 is positioned angularly; according to the principle expressed above, if the single-side U-shaped movable upright post 3 is pushed to cause the 2 groups of filter screen assemblies 9 to generate displacement or dislocation, adjustment is not needed, and after the 2-side U-shaped left and right movable upright posts 3 are pushed in place, the same friction force and pressure can be generated to push the 2 groups of filter screen assemblies 9 to reasonable positions; when the U-shaped left and right movable upright posts 3 at the side 2 are all pushed in place, a U-shaped is formed, then the U-shaped lower movable support 6 is pushed inwards (the buckle head 8 is pushed and installed firstly), the principle of inserting and pressing the U-shaped left and right movable upright posts 3 in the group 2 of filter screen assemblies 9 is the same as the principle of pushing in the U-shaped lower movable support 6, the U-shaped left and right lower movable support 6 at the other side is pushed inwards, the positioning angles are the same as the upper angle and are limited at 90 degrees, at the moment, the U-shaped cross beam 1, the U-shaped left and right movable upright posts 3 and the U-shaped left and right lower movable support 6 in the ventilation window are all pressed and attached to the reinforcing ventilation plate R angle 22 of the filter screen assemblies 9 at; the pressure of the positioning pin assembly 4 is applied to the reinforcing ventilating plate R corner 22 on the other side, a self-wrapping type filter screen assembly 9 fixing mode is finally formed, the hasps on the U-shaped left and right movable supports 6 are closed finally, the fixing of the whole ventilating window is completed, gaps of 3mm are formed in the periphery of the filter screen assembly and the inside of the ventilating frame, and the gaps of 3mm are used as assembling allowance of the self-wrapping type fixing mode.
When the filter screen assembly 9 is disassembled, the operation mode is opposite to the assembly mode, the hasp is loosened, the U-shaped lower movable support 6 is pushed, the opening angle is 90 degrees, the limiting effect is formed by the stop plate 24 of the U-shaped lower movable support 6, the R angle is contacted with the movable upright post rotating notch 17 when the angle is opened by 90 degrees to form positioning, the whole ventilation window forms a large U-shaped opening state at the moment, and the friction force and the pressure at the end of the filter screen assembly 9 disappear at the moment; the U-shaped movable upright posts 3 on the left side and the right side are pushed, the opening angle of each side of the U-shaped movable upright posts 3 on the left side and the right side can reach 90 degrees, so that the U-shaped movable upright posts are completely separated from the left side and the right side 2 of the filter screen assembly 9, and the friction force and the pressure on the left side and the right side disappear in the same way; and finally, holding the filter screen assembly 9 and slightly shaking the filter screen assembly 9, so that the filter screen assembly 9 is separated from the U-shaped cross beam 1.
When designing the ventilation window, the matching relation of all parts should also be considered. For example, the bending modes of the two ends of the U-shaped left and right movable upright posts 3 are not necessarily designed to be opened by 90 degrees, and can be changed according to the actual conditions, and the angle of the R angle can be changed as long as the two parts are free of interference when rotating; the installation position of the rotating shaft 2 only needs to meet the designed opening angle and the condition that parts do not interfere; the movable upright post rotation notch 17 and the stop plate 24 are designed to be positioned when the movable upright post is opened to a certain angle (not necessarily 90 degrees) as long as no interference exists in the closing process; the mounting position of the locating pin assembly 9 can be set according to the pressing force, because the filter screen assembly 9 is wrapped by itself around the locating pin assembly, the situation of large-area deformation and falling-off is avoided, and the structure form in the normal state does not need excessive pressing and meets the normal pressing force (0-gap linear contact); the preparation of filter screen subassembly 9, because of the form of the parcel of adoption certainly, first layer is strengthened ventilation frame 10 and can be adopted the middle 8 square holes of cutting of 2mm stainless steel board, bend all around and press the dead limit, in order to guarantee its roughness and pleasing to the eye degree, 60 mesh stainless steel net 11 can be adopted to the second floor, also can change the silk screen of different mesh according to the environment of difference, in order to satisfy the requirement under the different operational aspect, the stainless steel ventilation clamp plate 12 of third layer, the middle zone also can all be hollowed, need not to keep a perpendicular strip, the material thickness of clamp plate can design according to the demand, 1mm is all can to 2 mm. According to the actual operating environment, considering that a single set of filter screen assemblies 9 and a plurality of sets of filter screen assemblies 9 need to be repeatedly brushed for a long time, the material of the filter screen assemblies should not be lower than 304 stainless steel.
