Description

Technical Field

[0001] This utility model relates to the field of building ventilation shaft technology, and in particular to a rain shield for building ventilation shafts. Background Technology

[0002] Ventilation shafts are channels in buildings used for air circulation, enabling the exchange of indoor and outdoor air, fire prevention and smoke extraction, and the regulation of enclosed space environments. They need to be protected from rain because rainwater entering the shaft can cause water accumulation, damage equipment, and lead to dampness and mold growth inside the building, affecting structural safety and functionality.

[0003] The existing ventilation shaft's rain shield seals the shaft opening when rain is falling, and ventilation is achieved through the waterproof louvers on the side wall of the shaft, thus preventing rainwater from entering.

[0004] However, since ventilation shafts vary in size, while existing rain shields have fixed dimensions and can only be used with ventilation openings of specified sizes, installing ventilation shafts of different sizes requires replacing them with corresponding rain shields. This makes it impossible to use rain shields with ventilation shafts of different sizes, thus affecting their applicability. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing rain shields that cannot be used in ventilation shafts of different specifications, thus affecting the applicability of the rain shields, and to propose a rain shield for building ventilation shafts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rain shield for a building ventilation shaft is designed, comprising a first connecting plate, a second sealing strip on the lower surface of the first connecting plate, abutting the lower surface of the first connecting plate against the second connecting plate, and the lower surface of the second connecting plate against the first sealing strip. Both the first and second sealing strips are U-shaped. The first and second connecting plates are fixed together by a fixing mechanism. A sealing part is fixedly connected to one end of the first connecting plate. Both the sealing part and the second sealing strip abut against the second connecting plate. The first and second connecting plates are connected to the ventilation shaft by a connecting mechanism.

[0008] Preferably, both the first connecting plate and the second connecting plate are provided with transparent glass.

[0009] Preferably, the fixing mechanism includes a connecting column, which is fixedly connected to a first connecting plate. A fixing plate is fixedly connected to the lower end of the connecting column. Multiple through holes are equally spaced on the fixing plate, and a second bolt is installed in one of the through holes. The second bolt is threadedly connected to the second connecting plate.

[0010] Preferably, the connecting mechanism includes a fixing ear, which is fixedly connected to the outer wall of the ventilation shaft. A fixing block is fixedly connected to both the first connecting plate and the second connecting plate. A first bolt is threaded through the fixing block, and the first bolt is threaded through the fixing ear.

[0011] Preferably, both the first bolt and the second bolt are stainless steel bolts.

[0012] Preferably, a first connecting frame is fixedly connected to both sides of the first connecting plate, and a first rain guide plate is fixedly connected to the lower end of the first connecting frame.

[0013] Preferably, a second connecting frame is fixedly connected to both sides of the second connecting plate, and a second rain guide plate is fixedly connected to the lower end of the second connecting frame. The second rain guide plate is staggered at the lower end of the first rain guide plate.

[0014] Preferably, both the first and second rain guide plates are inclined, and the upper ends of both the first and second rain guide plates abut against the outer wall of the ventilation shaft.

[0015] The present invention provides a rain shield for a building ventilation shaft, which has the following advantages: by adjusting the length of the overlap between the first connecting plate and the second connecting plate, the length of the entire rain shield can be adjusted to adapt to ventilation shafts of different lengths, thus expanding the application range of the rain shield.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A rainproof plate for a building ventilation shaft includes a first connecting plate 1, a second sealing strip 13 on the lower surface of the first connecting plate 1, a second connecting plate 3 abutting the lower surface of the first connecting plate 1, and a first sealing strip 12 abutting the lower surface of the second connecting plate 3. Both the first sealing strip 12 and the second sealing strip 13 have a U-shaped structure. The first sealing strip 12 and the second sealing strip 13 abut against the ventilation shaft 4 to seal it and prevent rainwater from entering from the connection.

[0023] The first connecting plate 1 and the second connecting plate 3 are fixed together by a fixing mechanism. A sealing part 11 is fixedly connected to one end of the first connecting plate 1. The sealing part 11 and the second sealing strip 13 both abut against the second connecting plate 3. The two play a sealing role at the connection between the first connecting plate 1 and the second connecting plate 3 to prevent rainwater from leaking from the connection.

[0024] The first connecting plate 1 and the second connecting plate 3 are connected to the ventilation shaft 4 through a connecting mechanism. By adjusting the length of the overlap between the first connecting plate 1 and the second connecting plate 3, the length of the entire rain shield can be adjusted to accommodate ventilation shafts of different lengths, thus expanding the application range of the rain shield.

[0025] Both the first connecting plate 1 and the second connecting plate 3 are equipped with transparent glass 2 to ensure the brightness of the ventilation shaft.

[0026] The fixing mechanism includes a connecting column 17, which is fixedly connected to the first connecting plate 1. A fixing plate 14 is fixedly connected to the lower end of the connecting column 17. Multiple through holes 15 are evenly spaced on the fixing plate 14. A second bolt 16 is installed in one of the through holes 15. The second bolt 16 is threadedly connected to the second connecting plate 3. By placing the second bolt 16 in different through holes 15, it can be adapted to ventilation shafts 4 of different specifications, and at the same time, it can fix the first connecting plate 1 and the second connecting plate 3.

[0027] Example 2: Refer to Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, the connecting mechanism includes a fixing ear 8, which is fixedly connected to the outer wall of the ventilation shaft 4. A fixing block 7 is fixedly connected to both the first connecting plate 1 and the second connecting plate 3. A first bolt 5 is threaded through the fixing block 7, and the first bolt 5 is threaded through the fixing ear 8. By using multiple first bolts 5, the first connecting plate 1 and the second connecting plate 3 are fixed to the ventilation shaft 4 so that the rain shield can be disassembled and installed.

[0028] Both the first bolt 5 and the second bolt 16 are stainless steel bolts to prevent corrosion and avoid damage to them.

[0029] During installation, adjust the overlap length of the first connecting plate 1 and the second connecting plate 3 according to the length of the ventilation shaft. Then, place the second bolt 16 in the corresponding through hole 15 so that the second bolt 16 is threadedly connected to the second connecting plate 3, thereby fixing the first connecting plate 1 and the second connecting plate 3. Then, fix the fixing ear 8 to the outer wall of the ventilation shaft 4, and fix the fixing block 7 to the fixing ear 8 with the first bolt 5, thereby fixing the first connecting plate 1 and the second connecting plate 3 to the ventilation shaft 4.

[0030] Example 3: Reference Figure 1-4 As another preferred embodiment of the present utility model, based on embodiment 2, a first connecting frame 18 is fixedly connected to both sides of the first connecting plate 1, a first rain guide plate 9 is fixedly connected to the lower end of the first connecting frame 18, a second connecting frame 19 is fixedly connected to both sides of the second connecting plate 3, a second rain guide plate 10 is fixedly connected to the lower end of the second connecting frame 19, and the second rain guide plate 10 is staggered at the lower end of the first rain guide plate 9.

[0031] Both the first rain guide plate 9 and the second rain guide plate 10 are inclined, and their upper ends abut against the outer wall of the ventilation shaft 4. Since waterproof louvers are provided on both sides of the ventilation shaft 4, the rain guide plates guide the rainwater remaining on the first connecting plate 1 and the second connecting plate 3, preventing rainwater from flowing along the outer wall of the ventilation shaft 4 into the waterproof louvers and thus avoiding rainwater entering the ventilation shaft 4.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
