AI Technical Summary
Existing fire-fighting louvers in factory buildings struggle to balance rain protection and ventilation, especially when installed at heights, making them ill-suited for handling sudden weather disasters, and the auxiliary tools pose safety hazards.
A grid-type rainproof and ventilated louver is designed, employing a specific louver cross-section and fixing method to ensure high opening ventilation rate and rainproof effectiveness. Stable installation of the louver is achieved through hooks and fixing plates.
It achieves a balance between efficient ventilation and rain protection, is easy and safe to install, and avoids the safety hazards of traditional louvers.

Description
TECHNICAL FIELD
[0001] The utility model relates to fire safety technical field especially, relate to a grating type rainproof ventilation shutter. BACKGROUND
[0002] The fire shutter of factory building is a problem to guarantee enough ventilation under the premise of rainproof, the existing shutter is made a little big between the louver to guarantee its ventilation, but the rainproof effect will be discounted. If it rains heavily, the shutter is shielded.
[0003] And for tall factory building, the shutter is installed at high place, and it is difficult to effectively deal with sudden disaster weather. For example, using electric window closer and other auxiliary tools can only be used as a remedy, which brings safety hazards to factory equipment and products. INVENTION CONTENTS
[0004] The utility model discloses a grating type rainproof ventilation shutter, which has high opening ventilation rate and good rainproof effect by the configuration of the louver, and is not limited to horizontal and vertical installation.
[0005] The utility model adopts the technical scheme that:
[0006] A grating type rainproof ventilation shutter, characterized in that it comprises a window body and louvers arranged in the window body, the cross section of the louver is a rectangle connected with a flap shape, the flap shape is inclined in "> " shape, the connection position of the rectangle and the flap shape forms an upper hook, the bending position of the flap shape forms an inner hook, the upper end of the flap forms a lower hook, the upper end and the lower end of the cross section of the louver are flush, the top and the bottom of the window body are provided with fixed plates, the fixed plate comprises a fixed part and a clamping part, the fixed part is installed at the rear end of the window body, the clamping part is clamped between the hook of the rectangle and the upper hook of the bending position of the flap shape of the louver, and one side of the rectangle is an outdoor side.
[0007] Further, the head of the clamping part at the upper hook position is matched in the upper hook, and the root of the clamping part at the hook position is matched and clamped with the end of the hook.
[0008] Further, the distance between the adjacent louvers is 60 ± 1mm, and the vertical distance between the flap-shaped louvers is 40 ± 1mm.
[0009] Further, the louver is an integrally formed profile.
[0010] Further, when the window body is installed, the length direction of the louver is horizontal or vertical.
[0011] The utility model has the advantages that:
[0012] (1) installation is convenient, through the upper and lower fixed plate card installation louver, screw installation is exempted;
[0013] (2) has higher open ventilation rate and better rainproof effect. BRIEF DESCRIPTION OF DRAWINGS

[0025] The specific implementation of the grating type rainproof ventilation louver window of the utility model will be described in detail below in combination with the drawings.
[0026] Referring to the attached Figure 1 , 2 , the vertically installed ventilation rainproof louver 2 window of the patent comprises a window body 1 and louvers 2 arranged at intervals in the window body 1, the cross section of the louver 2 is a rectangle 3, an upper end of the rectangle 3 is connected with a folded plate shape 4, the folded plate shape 4 is inclined in "> " shape, an upper hook 5 is formed at the connecting position of the rectangle 3 and the folded plate shape 4, a clamping hook 6 is formed inside the bending part of the folded plate shape 4, a lower hook 7 is formed at the upper end of the folded plate shape 4, a semicircular arc 12 is formed at the outer side of the folded plate shape 4, the upper end and the lower end of the cross section of the louver 2 are flush surfaces 8, and the louver 2 is an integrally formed profile.
[0027] Referring to the attached Figure 3 , 4The top and bottom of the window body 1 are provided with fixed plates 9, which comprise fixed parts 10 and clamping parts 11. The fixed parts 10 are installed at the rear end of the window body 1, and the clamping parts 11 are clamped between the hooks 6 at the bending positions of the folding plates 4 of the louvers 2 and the upper hooks 5 of the rectangular plates 3. One side of the rectangular plate 3 is the outdoor side.
[0028] When the fixed plates 9 fix the louvers 2, the heads of the clamping parts 11 at the positions of the upper hooks 5 are matched in the upper hooks 5, and the roots of the clamping parts 11 at the positions of the hooks 6 are clamped with the ends of the hooks 6.
[0029] Continuing to refer to the drawings Figure 4 The interval b between the adjacent louvers 2 is 60±1mm, and the vertical distance a between the folding plate-shaped louvers is 40±1mm. The size can achieve the best ventilation and rainproof effect through measurement.
[0030] When the window body 1 is installed, the length direction of the louvers 2 can be horizontal or vertical, and the horizontal installation has better rainproof performance.
[0031] The above is only the preferred embodiment of the present application. It should be pointed out that, for the ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
