Description

Technical Field

[0001] The utility model relates to the technical field of passive buildings, in particular to a building waterproof and steam-isolating device. Background Art

[0002] In recent years, the development of energy-saving buildings and green buildings in my country has been supported and promoted by the state. Passive buildings, as green energy-saving buildings, have evolved from low-energy buildings. Passive buildings have efficient thermal insulation systems and doors and windows, design and construction without thermal bridges, excellent building air tightness, efficient fresh air heat recovery system, shading technology and auxiliary heating and cooling systems based on new energy. Through passive building technology, passive buildings basically do not need traditional centralized heating in winter and air conditioning in summer, so that the indoor temperature can be maintained at 20-26℃ all year round, and the humidity can be maintained at 30%-60%. The indoor air is fresh and there is no noise interference. Constant temperature, constant oxygen, constant humidity and low noise are achieved. While providing people with a comfortable and healthy indoor environment, the positioning board reduces the building energy consumption. Taking doors and windows as an example, existing passive buildings must not only meet the requirements of lighting, but more importantly, they must meet the requirements of insulation, water insulation and air tightness. The external door and window system is the weakest link in the insulation, waterproofing and air tightness of the enclosure structure. The energy consumption lost through the external doors and windows usually accounts for 30%-40% of the total energy consumption of the total building.

[0003] In the patent with publication number CN215255679U, a waterproof and vapor-isolating device for a passive building is proposed, comprising a fixed shell and a sliding shell, the waterproof and vapor-isolating device also comprising: an external channel, arranged on the side of the fixed shell facing the outside, for isolating external water vapor; an internal channel, located on the inner side of the fixed shell, connected to the external channel through a guide hole, for secondary blocking of water vapor; and an elastic sheet assembly, telescopically arranged in the external channel, slidingly cooperating with the movement of the sliding shell, for blocking the external channel from the external air; the elastic sheet assembly is connected to the outside through an overflow port, for draining the accumulated water to the outside.

[0004] In the above patent, the door and window structure is sealed by an elastic component assembly. Since the elastic component assembly will always generate friction with the door and window structure when the door and window structure moves, the gap between the elastic component and the door and window structure becomes larger after the elastic component is worn too much, resulting in a reduction in the waterproof and vapor-proof effect. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a building waterproof and steam-isolating device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] As a further solution of the utility model, the reset assembly includes a compression spring sleeved on the outer surface of the guide rod, and the compression spring is arranged between the push block and the end of the air pump tube.

[0011] As a further solution of the utility model, a lock opening is provided on the outer surface of the lock handle, and a lock buckle matching the lock opening is fixedly mounted on the outer surface of the window frame.

[0012] As a further solution of the utility model, a sliding groove for the window frame to slide on the window frame is formed between a convex rafter far away from the airbag and the partition.

[0013] The beneficial effects of the utility model are:

[0025] In this embodiment, the pumping mechanism includes two pumping tubes 7 symmetrically fixedly mounted on the outer surface of the partition 5, and a guide rod 9 is inserted through the adjacent ends of the two pumping tubes 7. A piston 8 is slidably mounted inside the pumping tube 7. The end of the guide rod 9 away from the rotating shaft 14 is fixedly mounted on the outer surface of the piston 8, and the other end of the guide rod 9 is fixedly mounted with a push block 11. The end of the pumping tube 7 away from the rotating shaft 14 is connected to the inside of the airbag 4 through a pipe 10. A reset component is provided on the outer surface of the guide rod 9, and a push component for pushing the piston 8 to move is provided on the outer surface of the rotating shaft 14. The push component is fixedly mounted on a cam 13 on the outer surface of the rotating shaft 14, and the push block 11 abuts against the outer surface of the cam 13.

[0026] When in use, by turning the lock handle 15 upward, the lock handle 15 drives the cam 13 to rotate through the rotating shaft 14, so that the cam 13 pushes the push block 11, and the push block 11 pushes the piston 8 toward the direction of the pipe 10 through the guide rod 9, so that the piston 8 squeezes the air in the inflation pipe 7 into the airbag 4 through the pipe 10, so that the airbag 4 installed around the window frame 2 expands outward, and the airbag 4 presses against the gap between the window frame 2 and the window frame 1, thereby improving the sealing effect of the window frame 2, and can effectively prevent external water vapor from entering the room.

[0027] In this embodiment, the reset assembly includes a compression spring 12 sleeved on the outer surface of the guide rod 9. The compression spring 12 is arranged between the push block 11 and the end of the air pump 7. The compression spring 12 is used to push the push block 11 to move, so that the push block 11 pulls the piston 8 to reset through the guide rod 9.

[0028] In this embodiment, a lock hole 16 is provided on the outer surface of the lock handle 15, and a lock buckle 17 matching the lock hole 16 is fixedly installed on the outer surface of the window frame 1. After the lock handle 15 is rotated upward to a horizontal position, the lock hole 16 provided on the lock handle 15 will be inserted into the lock buckle 17 installed on the outer side of the window frame 1, so that the lock handle 15 and the lock buckle 17 can tightly lock the window frame 1 and the window frame 2.

The window frame 2 is slidably installed with the guide rail on the window frame 1 through the slide groove 6, so that the window frame 2 forms a sliding window.

[0030] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: after closing the window frame 2, the lock handle 15 is rotated upward, so that the lock handle 15 drives the cam 13 to rotate through the rotating shaft 14, so that the cam 13 pushes the push block 11, so that the push block 11 pushes the piston 8 toward the direction of the pipe 10 through the guide rod 9, so that the piston 8 squeezes the air in the air pump 7 into the air bag 4 through the pipe 10, so that the air bag 4 installed around the window frame 2 expands outward, so that the air bag 4 is pressed against the gap between the window frame 2 and the window frame 1, thereby improving the sealing effect of the window frame 2, and can effectively prevent external water vapor from entering the room;

[0031] After the lock handle 15 is turned upward to a horizontal position, the lock opening 16 provided on the lock handle 15 will be inserted into the lock buckle 17 installed on the outer side of the window frame 1, so that the lock handle 15 and the lock buckle 17 can tightly lock the window frame 1 and the window frame 2;

[0032] When it is necessary to open the window frame 2, the lock handle 15 is rotated in the opposite direction, so that the lock handle 15 drives the cam 13 to rotate in the opposite direction through the rotating shaft 14, so that the compression spring 12 sleeved on the outer surface of the guide rod 9 can push the push block 11 to move, thereby resetting the piston 8 and sucking the gas injected into the air bag 4 back into the inflation pipe 7, so that the air bag 4 can be contracted, thereby pushing and pulling the window frame 2 to move.
