Description

Technical Field

[0001] The utility model relates to the technical field of shutters, in particular to a rainproof shutter air outlet. Background Art

[0002] A louver is a device used to regulate air circulation and temperature inside a building. It usually consists of a series of parallel metal or plastic sheets that can be rotated or tilted to control the air in and out. Louver vents are usually installed on the exterior walls or ceilings of buildings. By adjusting the angle of the sheets, the direction and speed of indoor air can be controlled. Louver vents are often used in ventilation systems. They can adjust the freshness of the air as well as control the temperature and humidity in the room. They are an effective air conditioning system accessory.

[0003] However, the existing louver vents usually adjust the blades to tilt downward so that rainwater flows along the surface of the blades to the outside to prevent rainwater from entering the room. However, since the blades are rotatable, there are gaps between the top and bottom blades and the outer frame, and rainwater will pass through the louver vents into the room through these gaps. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a rainproof louver air vent which can solve the problem of existing louver air vents having gaps between the top and bottom blades and the outer frame, and rainwater passing through the louver air vents into the room through these gaps. The utility model can fill the gaps between the blades and the outer frame to prevent rainwater from entering the room through these gaps, and can also lock the louver blades to avoid gaps between the louver blades, thereby improving the rainproof performance of the louver air vent.

At this time, the louver is limited and cannot rotate, and the louvers are tightly fitted to each other to avoid gaps between the louvers, thereby improving the rainproof performance of the louver air outlet. At this time, the gap between the top louver and the fixing seat is also closed, and rainwater cannot enter the room through the gap.

[0008] Furthermore, a limiting groove is provided inside the fixing seat, the diameter of the limiting groove is greater than the width of the limiting rod, and the diameter of the limiting groove is less than the sum of the lengths of the two limiting rods.

[0009] Through the above technical solution, the position of the limit rod can be adjusted by rotating the rotating shaft, so that the rotating shaft can drive the limit rod to slide upward and be stored in the interior of the limit groove, or the rotating shaft can be positioned at the lower end of the limit groove through the limiting of the limit rod.

[0010] Furthermore, a baffle is provided on the inner side of the fixing seat, and the height of the baffle is greater than the height of the clamping block.

[0011] Through the above technical solution, the baffle can block rainwater, thereby preventing rainwater from entering the room through the gap between the lowest louver and the outer frame.

[0014] Furthermore, two clamping blocks are provided, and the clamping blocks are symmetrically distributed about the longitudinal center line of the louver blade.

[0015] Through the above technical solution, the clamping block is clamped into the gap between the bottom louver and the outer frame, and the closing block is clamped into the gap between the top louver and the fixed seat, cooperating with each other to limit the louver so that the louver cannot rotate.

[0016] Furthermore, a drainage groove is provided at the bottom of the fixing seat, and the length of the drainage groove is smaller than the distance between the two clamping blocks.

[0017] Through the above technical solution, after the louver blades are tilted downward, rainwater will flow downward along the surface of the louver blades and be discharged through the drainage grooves, thereby preventing rainwater from accumulating between the louver blades and the outer frame.

[0018] Furthermore, the connection between the connecting shaft and the rotating shaft is a rotational connection, and two limit rods are provided, and the limit rods are symmetrically distributed about the longitudinal center line of the rotating shaft.

[0021] Through the above technical solution, the slide plate forms a telescopic structure inside the fixed seat through the reset spring, which makes it easy for the reset spring to drive the connecting plate and the connecting shaft connected to the slide plate to reset.

[0022] Compared with the prior art, the utility model provides a rainproof louver vent, which has the following beneficial effects:

[0023] In the utility model, the closing block is inserted into the gap between the uppermost louver and the fixing seat to close the gap, thereby preventing rainwater from entering the room through the gap. In the process, the two clamping blocks are inserted into the gap between the lowermost louver and the fixing seat. At this time, the louver is limited and cannot rotate, and the louvers are tightly fitted to each other to avoid gaps between the louvers, thereby improving the rainproof performance of the louver air outlet.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 6 The utility model provides a technical solution: a rainproof louver vent, comprising an outer frame 1, a fixed seat 2 is fixedly connected to one side of the outer frame 1, a louver blade 3 is arranged inside the fixed seat 2, a closing component is arranged inside the fixed seat 2, the closing component is used to close the gap between the outer frame 1 and the louver blade 3, the closing component comprises a closing block 4, connecting rods 6 are connected to the two sides of the closing block 4, a slider 7 is connected to the lower end of the connecting rod 6, a limited block 8 is connected to one side of the slider 7, a clamping block 9 is connected to one side of the limited block 8, the slider 7 and the clamping block 9 are connected to the fixed seat 2 in a sliding connection, the limited block 8 is connected to the fixed seat 2 in a rotating connection, two clamping blocks 9 are provided, and the clamping blocks 9 are symmetrically distributed about the longitudinal center line of the louver blade 3;

[0033] The principle that can improve the rainproof performance of the louver vent is: when encountering rainy weather, first adjust the louver 3 to make its blades tilt downward, then pull the rotating shaft 14 downward, the rotating shaft 14 drives the slide plate 11 to move downward through the connecting shaft 13, and the slide plate 11 drives the closing block 4 to move downward synchronously through the connecting plate 5, so that the closing block 4 is stuck in the gap between the uppermost louver 3 and the fixing seat 2. In this process, the closing block 4 drives the connecting rod 6 to move downward synchronously, and the connecting rod 6 moves downward and pushes the slider 7. The slider 7 drives the limit block 8 to rotate during the downward sliding process, so that the limit block 8 drives the clamping block 9 to slide upward, so that the clamping block 9 is stuck in the gap between the lowermost louver 3 and the outer frame 1. At this time, the louver 3 is limited and cannot rotate, and the louver 3 is tightly fitted to each other to avoid gaps between the louver 3, thereby improving the rainproof performance of the louver vent, and at this time, the gap between the uppermost louver 3 and the fixing seat 2 is also closed, and rainwater cannot enter the room through the gap.

[0034] See also Figure 1-Figure 4 , see Figure 1-Figure 6 A connecting plate 5 is fixedly connected to the upper surface of the closing block 4, and a locking assembly is connected to the upper end of the connecting plate 5. The locking assembly includes a connecting shaft 13, a rotating shaft 14 and a limiting rod 15. The locking assembly is used to lock the closing assembly. A limiting groove 16 is provided inside the fixing seat 2. The diameter of the limiting groove 16 is greater than the width of the limiting rod 15, and the diameter of the limiting groove 16 is less than the sum of the lengths of the two limiting rods 15. The connection mode between the connecting shaft 13 and the rotating shaft 14 is a rotational connection. Two limiting rods 15 are provided, and the limiting rods 15 are symmetrically distributed about the longitudinal center line of the rotating shaft 14.

[0035] The principle of locking the closing component is: after the rotating shaft 14 is rotated 90°, the rotating shaft 14 drives the limiting rod 15 to rotate 90° synchronously. Since the diameter of the limiting groove 16 is smaller than the sum of the lengths of the two limiting rods 15, the limiting rod 15 can limit the rotating shaft 14 at this time, so that the rotating shaft 14 is positioned at the lower end of the limiting groove 16. At this time, the connecting shaft 13 and the slide plate 11 connected to the rotating shaft 14 cannot slide, and the closing block 4 connected to the slide plate 11 through the connecting plate 5 is positioned.

[0036] See also Figure 1-Figure 2 A baffle 17 is provided on the inner side of the fixing seat 2 , and the height of the baffle 17 is greater than the height of the block 9 .

[0037] The function of the baffle 17 is that the baffle 17 can block rainwater, thereby preventing rainwater from entering the room through the gap between the lowest louver 3 and the outer frame 1.

[0038] See also Figure 1-Figure 2 A drainage groove 10 is provided at the bottom of the fixing seat 2 , and the length of the drainage groove 10 is less than the distance between the two blocks 9 .

[0039] It should be noted that after the louver 3 tilts downward, rainwater will flow downward along the surface of the louver 3 and be discharged through the drainage groove 10, thereby preventing rainwater from accumulating between the louver 3 and the outer frame 1.

[0040] See also Figure 1-Figure 6 The upper end of the connecting shaft 13 is fixedly connected to a slide plate 11, one side of the slide plate 11 is fixedly connected to the connecting plate 5, the upper surface of the slide plate 11 is connected to a return spring 12, and the other end of the return spring 12 is fixedly connected to the fixing seat 2;

[0041] It is worth mentioning that the slide plate 11 forms a telescopic structure inside the fixed seat 2 through the reset spring 12. After the rotating shaft 14 is rotated 90° in the opposite direction to reset the limit rod 15, the reset spring 12 drives the connecting plate 5 and the connecting shaft 13 connected to the slide plate 11 to reset, so that the rotating shaft 14 drives the limit rod 15 to slide upward and be received in the limit groove 16.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
