Description

Technical Field

[0001] The utility model relates to the technical field of ventilation structures, in particular to an energy-saving ventilation structure for buildings. Background Art

[0002] Roof vent caps are also called roof natural ventilators or roof natural ventilators. They are based on the aerodynamic wind load model theory that "when wind acts on an object, the windward side acts as pressure, while the leeward side and the downwind side act as suction." They are installed on the top of a building and connected to the interior to ventilate the building.

[0003] In the prior art, the installation of the roof vent cap is to fix the roof vent cap to the roof with screws. In order to prevent rainwater from entering the building through the installation gap, it is also necessary to apply glue to the installation gap to seal the gap, so the installation of the roof vent cap is relatively cumbersome.

[0004] Therefore, an energy-saving ventilation structure for buildings is proposed to solve the above problems. Utility Model Content

[0012] The present invention has the following beneficial effects: the present invention adopts an energy-saving ventilation structure, and a hole adapted to the external threaded barrel of the device is reserved on the top of the building, and the hole is connected to the interior of the building. The limiting ring is aligned with the hole and pressed downward with force to retract the limiting assembly into the limiting ring until the limiting ring extends into the building and is located below the top wall of the building's inner cavity. At this time, the limiting assembly moves to its opposite side to reset, and the sealing installation assembly is rotated to move the sealing installation assembly toward the limiting ring until the bottom of the sealing installation assembly and the top of the limiting assembly clamp the top of the building, thereby completing the installation of the device, and the sealing installation assembly fits tightly against the top of the building to form a seal for the gap, which has the advantages of quick installation and no need to apply additional glue to seal the installation gap.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4, an energy-saving ventilation structure for buildings, including a ventilation hood 1, an externally threaded tube 2, the externally threaded tube 2 is installed at the bottom of the ventilation hood 1, and the interior of the ventilation hood 1 is connected to the externally threaded tube 2; a limiting ring 3 is fixedly installed at the bottom of the externally threaded tube 2, the interior of the limiting ring 3 is provided with limiting components 4 distributed in an annular array and extending to the outside thereof, and the outside of the externally threaded tube 2 is provided with a sealing installation component 5 threadedly connected thereto; the limiting component 4 includes an assembly hole 401, a spring 402 and a limiting slider 403, the outside of the limiting ring 3 is provided with assembly holes 401 distributed in an annular array, the inside of the assembly holes 401 are provided with springs 402, and the opposite side of the spring 402 is fixedly connected with a limiting slider 403 that is slidably connected to the assembly hole 401 and extends to the outside of the limiting ring 3.

[0021] Furthermore, the opposite ends of the limiting sliders 403 are both rounded 6 , and the tops of the limiting sliders 403 are both flat 7 .

[0022] Furthermore, the sealing installation assembly 5 includes an internal threaded ring 501, a clamping ring 502 and a rubber sealing gasket 503. The outer side of the external threaded barrel 2 is threadedly connected to the internal threaded ring 501. The bottom of the internal threaded ring 501 is rotatably connected to the clamping ring 502 located on the outer side of the external threaded barrel 2. The bottom of the clamping ring 502 is fixedly connected to the rubber sealing gasket 503.

[0023] By rotating the internal thread ring 501 to make it move toward the limiting ring 3 , when the rubber sealing gasket 503 contacts the top of the building, the internal thread ring 501 is further rotated to make it move toward the limiting ring 3 .

[0024] Furthermore, a handle 8 symmetrically distributed on the left and right is fixedly connected to the outside of the external threaded barrel 2 .

[0025] The working principle of this utility model:

[0026] In the present invention, first, a hole is reserved on the top of the building to match the external threaded barrel 2 of the device, and the hole is connected to the interior of the building. The limiting ring 3 is aligned with the hole, and the handle 8 is held with both hands and pressed down with force. When the round head 6 on the opposite side of the limiting slider 403 contacts the side wall of the hole, the limiting slider 403 moves to the opposite side, so that the limiting slider 403 is retracted into the assembly hole 401 and the spring 402 is compressed; then, when the limiting ring 3 is extended into the building and is located below the top wall of the building's inner cavity, the spring 402 recovers its elastic deformation, causing the limiting slider 403 to move to the opposite side;

[0027] The sealing installation assembly 5 includes an internal threaded ring 501, a clamping ring 502 and a rubber sealing gasket 503. The outer side of the external threaded barrel 2 is connected to the internal threaded ring 501 through a thread. The bottom of the internal threaded ring 501 is rotatably connected to the clamping ring 502 located on the outer side of the external threaded barrel 2. The bottom of the clamping ring 502 is fixedly connected to the rubber sealing gasket 503. Therefore, by rotating the internal threaded ring 501, it moves toward the limiting ring 3. When the rubber sealing gasket 503 contacts the top of the building, continue to rotate the internal threaded ring 501 to It moves toward the limiting ring 3. At this time, the internal threaded ring 501 rotates relative to the clamping ring 502. The clamping ring 502 is in contact with the top of the building due to the rubber sealing gasket 503 at the bottom. The clamping ring 502 is stationary relative to the top of the house until the flat surface 7 at the top of the limiting slider 403 contacts the top wall of the inner cavity of the building. At the same time, the rubber sealing gasket 503 at the bottom of the clamping ring 502 is elastically deformed, thereby sealing the gap between the clamping ring 502 and the top of the building, completing the installation of the device.
