[0001] The utility model relates to the field of computer rooms or cabinets, in particular to a normally open air outlet louver for rain protection and air guiding. Background Technique
[0002] In computer rooms and cabinets, multiple servers are often arranged. During the operation of the servers, a large amount of heat is generated and cooling treatment is required. In order to reduce energy consumption, ventilation can be used for cooling, sending natural fresh air outdoors into the computer room or cabinet to take away the heat of the servers.
[0003] In order to ensure the smooth discharge of fresh air, the air outlet window needs to be kept normally open, but it is easily affected by external rainwater, resulting in water inlet problems when the wind and rain are relatively large. In the prior art, self-closing louvers are mostly used for rain protection. The self-closing louvers are actively closed under the action of force when the wind and rain are relatively large, which can avoid rainwater from entering the room, but it will also cause problems that the indoor air cannot be discharged normally and improvement is needed. Summary of the Utility Model
[0004] The main technical problem to be solved by the utility model is to provide a normally open air outlet louver for rain protection and air guiding, which can prevent rain and guide air to ensure normal open air outlet.

The fixed blades are arranged in the window frame at intervals up and down. The rotating shaft is arranged in the window frame at intervals up and down and is located inside the fixed blades. The top of the movable blade is rotatably arranged on the rotating shaft. The first limit pin is arranged in the window frame and is located below the front side of the rotating shaft to limit the outward turning of the movable blade. The second limit pin is arranged in the window frame and is located below the rotating shaft and the first limit pin to limit the inward turning of the movable blade. A first air outlet channel obliquely pointing to the lower outside is formed between two adjacent movable blades up and down. The fixed blade includes a first blade and a second blade. The first blade obliquely points to the upper outside. The second blade is horizontally arranged at the inner end of the first blade. A second air outlet channel obliquely pointing to the upper outside is formed between two adjacent first blades up and down. A horizontal air outlet channel connecting the first air outlet channel and the second air outlet channel is formed between two adjacent second blades up and down.
[0006] In a preferred embodiment of the utility model, when the movable blade turns inward and contacts the second limit pin, it is limited. At this time, the movable blade forms a certain angle with the vertical plane.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 to 4 , the embodiments of the present utility model include:
[0021] As Figures 1 to 4 shown, the normally open air outlet louver for rainproof and air guiding includes: a window frame 1, fixed blades 6, a rotating shaft 2, a first limit pin 8, a second limit pin 4, and movable blades 3. The fixed blades 6 are arranged at intervals up and down in the window frame 1. The rotating shaft 2 is arranged at intervals up and down in the window frame and is located inside the fixed blades 6. The top of the movable blade 3 is rotatably arranged on the rotating shaft 2. A sleeve through which the rotating shaft 2 passes can be bent at the top of the movable blade 3 to ensure the flexibility of the movable blade 3 to flip around the rotating shaft 2.
[0022] In order to limit the flipping of the movable blade 3, the first limit pin 8 is arranged in the window frame 1 and below the front side of the rotating shaft 2 to limit the outward flipping of the movable blade 3. When the indoor air outlet airflow is large, it can blow the outward flipping of the movable blade 3 and be limited by the first limit pin 8. As Figure 3 shown, the maximum opening degree of the air outlet is maintained.
[0023] The second limit pin 4 is arranged in the window frame 1 and below the middle between the rotating shaft 2 and the first limit pin 8 to limit the inward flipping of the movable blade 3. When the movable blade 3 flips inward and contacts the second limit pin 4, it is limited. As Figure 2 shown, at this time, the movable blade 3 forms a certain angle with the vertical plane, so that a first air outlet channel 11 obliquely pointing downward and outward is formed between two adjacent movable blades up and down. When the indoor air outlet airflow is small or the outdoor wind force is large, the movable blade 3 flips inward and passes through the first limit pin 8, maintaining the minimum opening degree of the first air outlet channel 11 and ensuring the normally open air outlet.
[0024] In this embodiment, the fixed blade 6 includes a first blade 61 and a second blade 62. The first blade 61 obliquely points upward and outward. The second blade 62 is horizontally arranged at the inner end of the first blade 61. A second air outlet channel 12 obliquely pointing upward and outward is formed between two adjacent first blades 61 up and down. A horizontal air outlet channel 10 connecting the first air outlet channel 11 and the second air outlet channel 12 is formed between two adjacent second blades 62 up and down. The indoor air flows outwards through the first air outlet channel 11, the horizontal air outlet channel 10, and the second air outlet channel 12 in sequence.
[0025] As Figure 2As shown in the figure, connection pieces 63 that fit against the inner side walls of the window frame 1 are respectively bent at both ends of the first blade 61 and the second blade 62. A rivet 7 that penetrates the connection pieces 63 is provided on the window frame 1, facilitating assembly. The first blade 61, the second blade 62, and the connection pieces 63 adopt an integrated structure, with stable structure.
[0026] In this embodiment, the first limit pin 8 and the second limit pin 4 are respectively arranged on both sides of the window frame 1 to limit the flipping stroke at both ends of the movable blade 3. Shock-absorbing rubber sleeves 5 are respectively arranged on the outer circles of the first limit pin 8 and the second limit pin 4. During the flipping process of the movable blade 3, it contacts the shock-absorbing rubber sleeves 5 for limiting, reducing the noise problem.
[0027] As Figure 3 shown, when the movable blade 3 flips outwards and contacts the first limit pin 8, it is limited. At this time, the end of the movable blade 3 extends below the second blade 62 in front. External rainwater enters the front of the movable blade 3 along the first blade 61 and the second blade 62, and flows downward along the inclination angle of the movable blade 3, avoiding the problem of entering the room. As Figure 2 shown, when the movable blade 3 flips inwards and contacts the second limit pin 4, it moves away from the second blade 62. External rainwater flows along the first blade 61 to the second blade 62, and finally flows downward along the vertical channel between the second blade 62 and the movable blade 3, also avoiding the problem of rainwater entering the room. A diversion trough can be installed below the window frame 1 to send the rainwater to a designated position.
[0028] In this embodiment, an arc-shaped bent plate 9 is convexly arranged at the end of the movable blade 3. During the process of rainwater flowing downward along the inclined surface of the movable blade 3, a parabola is formed when passing through the arc-shaped bent plate 9. As Figure 3 shown, it is beneficial to use the air outlet at the bottom of the movable blade 3 to send the rainwater out of the room.
[0029] In summary, a normally open air outlet louver for rain prevention and air guiding pointed out by the present utility model can not only prevent rainwater from entering the room, but also conduct normal air outlet, which is beneficial to ventilation and cooling in the room. In addition, the indoor air inlet takes other windows separately, without mutual influence.
[0030] The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
