Door and window sealing structure and door and window thereof

Abstract

This utility model discloses a door and window sealing structure and related doors and windows, belonging to the technical field of door and window sealing components. The device includes a fixed sealing element and a movable sealing element. The fixed sealing element includes a gasket with a protrusion. The movable sealing element includes a tubular negative pressure sleeve with a negative pressure chamber inside. One side of the tubular negative pressure sleeve has a through opening that mates with the protrusion. Both the protrusion and the tubular negative pressure sleeve are made of elastic material. In use, when the door panel impacts the door frame under external force, the protrusion first inserts into the through opening. The tubular negative pressure sleeve itself has a certain elastic deformation capacity, providing cushioning protection for the door frame. Furthermore, at the moment of impact, because the gas inside the negative pressure chamber can only overflow from the constant pressure one-way valve, the gas inside the negative pressure chamber has a damping effect on the door panel, reducing the sound generated during impact and ensuring a good noise reduction effect.

Description

Technical Field

[0001] This utility model relates to the technical field of door and window sealing components, and in particular to a door and window sealing structure and the door and window thereof. Background Technology

[0002] Door and window sealing components are a crucial part of the door and window structure, mainly composed of sealing strips, weatherstripping, etc. These components are installed at the joints between glass and frame / sash, and frame and sash, playing an important role in waterproofing, dustproofing, sealing, sound insulation, and heat preservation.

[0003] Most doors and windows currently in use consist of a door frame, door panel, door lock, and seals. The door lock secures the door frame and door panel, allowing the seals to be clamped between them, achieving a sealing effect. In addition to sealing, the seals also act as shock absorbers, reducing the impact force on the door frame and door panel under external forces.

[0004] The shortcomings of the existing technical solutions are that the current sealing components do not perform well in terms of shock absorption, which makes the door panel prone to impact with the door frame when subjected to external wind or human pushing, resulting in greater vibration and noise, which greatly affects the user's experience. Utility Model Content

[0005] This utility model provides a door and window sealing structure and the door and window thereof, which can solve the problem in the prior art that when the door panel is subjected to external wind force or human pushing, it is easy to collide with the door frame, resulting in greater vibration and noise.

[0006] A door and window sealing structure includes a fixed sealing element and a movable sealing element. The fixed sealing element includes a gasket with a protrusion. The movable sealing element includes a tubular negative pressure sleeve with a negative pressure cavity inside. A through opening that mates with the protrusion is provided on one side of the tubular negative pressure sleeve. Both the protrusion and the tubular negative pressure sleeve are made of elastic material.

[0007] As a further embodiment of this utility model: both sides of the protrusion are provided with slopes, and the inner side of the through opening is provided with an elastic clamp that cooperates with the slopes on both sides of the protrusion.

[0008] As a further embodiment of this utility model: the inclination of the slopes on both sides of the protrusion is greater than the inclination of the corresponding elastic clamp.

[0009] As a further embodiment of this utility model: the protrusion, the tubular negative pressure sleeve, and the elastic clamp are all made of solid silicone.

[0010] As a further embodiment of this utility model: at least two sets of constant pressure check valves are provided on the side of the tubular negative pressure sleeve, and the output end of at least one set of constant pressure check valves faces the negative pressure chamber, while the output end of at least one set of constant pressure check valves faces the outside.

[0011] As a further embodiment of this utility model: each set of constant pressure check valves includes a fixed sleeve that is fixedly inserted through the side wall of the tubular negative pressure sleeve. One end of the fixed sleeve is the input end and the other end is the output end. An inner sleeve is coaxially fixedly connected inside the fixed sleeve. A venting groove is provided on the inner wall of the inner sleeve. One end of the venting groove extends to the end of the inner sleeve near the output end and communicates with the external space of the fixed sleeve. The other end of the venting groove is located in the middle of the inner sleeve. A slider is slidably arranged inside the inner sleeve. An elastic component that cooperates with and connects to the slider is provided on one side of the inner sleeve.

[0012] As a further embodiment of this utility model: an output end baffle is fixedly connected to the inner sleeve near the output end, and the elastic component includes a spring that is configured to cooperate between the output end baffle and the slider.

[0013] As a further embodiment of this utility model: an input end baffle is fixedly provided on the side of the fixed sleeve near the inlet / outlet end, and there is an opening between the input end baffle and the side wall of the fixed sleeve to facilitate air circulation.

[0014] A door and window with a door and window sealing structure includes a door frame and a door panel. The door panel is movably hinged to the inside of the door frame. The gasket is fixedly disposed on the edge of the door panel near the door frame. The tubular negative pressure sleeve is fixedly disposed on the inside of the door frame and cooperates with the protrusion.

[0015] As a further embodiment of this utility model: an extension is provided on the side where the door panel and the door frame are hinged to each other.

[0016] The beneficial effects of this utility model are:

[0017] 1. When this utility model is in use, when the door panel hits the door frame under the action of external force, the protrusion will first insert into the through opening. The tubular negative pressure sleeve itself has a certain elastic deformation capability, which buffers and protects the door frame. At the moment of impact, the air between the elastic plates of the protrusion is pushed into the negative pressure chamber, and the tubular negative pressure sleeve itself deforms. Since the gas inside the negative pressure chamber can only overflow from the constant pressure one-way valve, the gas inside the negative pressure chamber produces a damping effect on the door panel, reducing the sound generated during the impact and ensuring a better noise reduction effect.

[0018] 2. When the door is closed, the protrusion is inserted into the through opening under external force. When the protrusion slides between the elastic clamps, it pushes the air between the elastic clamps into the negative pressure chamber, causing the air pressure inside the negative pressure chamber to suddenly increase. This triggers the constant pressure one-way valve for outputting gas. The air inside the negative pressure chamber is squeezed into the corresponding fixed sleeve, pushing the slider to move along the inner sleeve. The spring is compressed, and the vent groove inside the inner sleeve is exposed, allowing the airflow inside the negative pressure chamber to connect with the outside through the vent groove. The airflow inside the negative pressure chamber overflows until the air pressure inside the negative pressure chamber can no longer push the slider. The slider returns to its original position under the action of the spring. At this time, the protrusion is fixed under the action of friction and the negative pressure inside the negative pressure chamber, completing the fixation of the door frame and door panel and ensuring its sealing effect.

Detailed Implementation

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0029] like Figures 1 to 7 As shown in the figure, an embodiment of the present utility model provides a door and window with a door and window sealing structure. The door and window includes a door frame 1 and a door panel 3. The door panel 3 is movably hinged to the inside of the door frame 1. An extension 301 is provided on the side of the door panel 3 that is hinged to the door frame 1, so that the sealing structure on the door panel 3 can be completely embedded inside the door frame 1.

[0030] The sealing structure includes a fixed seal 2 and a movable seal 4. The fixed seal 2 includes a gasket 201, which is fixedly disposed on the edge of the door panel 3 near the door frame 1. A protrusion 202 is provided on the gasket 201. The movable seal 4 includes a tubular negative pressure sleeve 401, which is fixedly disposed inside the door frame 1 and mates with the protrusion 202. A negative pressure cavity 402 is provided inside the tubular negative pressure sleeve 401, and a through opening 403 is provided on one side of the tubular negative pressure sleeve 401 to mate with the protrusion 202. Both sides of the protrusion 202 are sloped, and an elastic clamp 404 mates with the slopes on both sides of the protrusion 202 inside the through opening 403. Figure 3 As shown, the slope of both sides of the protrusion 202 is greater than the slope of the corresponding elastic clamp 404, so that when the protrusion 202 is inserted between the elastic clamps 404, it will be clamped by the two sets of elastic clamps 404, thus fixing the protrusion 202. The protrusion 202, the tubular negative pressure sleeve 401, and the elastic clamps 404 are all made of solid silicone, preferably high tear-resistant solid silicone. The surfaces of the elastic clamps 404 and the protrusion 202 are covered with a layer of flexible silicone as a sealing contact material.

[0031] At least two sets of constant pressure check valves 5 are provided on the side of the tubular negative pressure sleeve 401. At least one set of constant pressure check valves 5 has its output end facing the negative pressure chamber 402, and at least one set has its output end facing the outside. These constant pressure check valves 5 differ only in their output direction; their internal structures are identical. They are used to output airflow unidirectionally inward and outward under certain pressure conditions. Each set of constant pressure check valves 5 includes a fixed sleeve 501 that is fixedly inserted through the side wall of the tubular negative pressure sleeve 401. One end of the fixed sleeve 501 is the input end, and the other end is the output end. An inner sleeve 502 is coaxially fixedly connected inside the fixed sleeve 501. A venting groove 503 is provided on the inner wall of the inner sleeve 502. One end of the venting groove 503 extends to the end of the inner sleeve 502 near the output end and communicates with the external space of the fixed sleeve 501. Figure 3 As shown, the other end of the venting groove 503 is located in the middle of the inner sleeve 502.

[0032] A slider 506 is slidably mounted inside the inner sleeve 502. An output end baffle 504 is fixedly connected to the inner sleeve 502 near the output end. A spring 505 is fitted between the output end baffle 504 and the slider 506. An input end baffle 507 is fixedly mounted on the fixed sleeve 501 near the inlet / outlet end. An opening for air circulation exists between the input end baffle 507 and the side wall of the fixed sleeve 501. When the door is closed, the protrusion 202 is inserted into the through opening 403 under the action of external force. When the protrusion 202 slides between the elastic clamps 404, it pushes the air between the elastic clamps 404 into the negative pressure chamber 402, causing the air pressure inside the negative pressure chamber 402 to suddenly increase. This triggers the constant pressure check valve 5 for outputting gas to the outside. The air inside the negative pressure chamber 402 is squeezed into the corresponding fixed sleeve 501, pushing the slider 506 to move along the inner sleeve 502. The spring 505 is compressed, and the venting groove 503 inside the inner sleeve 502 is exposed, allowing the airflow inside the negative pressure chamber 402 to connect with the outside through the venting groove 503. The airflow inside the negative pressure chamber 402 overflows until the air pressure inside the negative pressure chamber 402 can no longer push up the slider 506. The slider 506 is reset under the action of the spring 505. At this time, the negative pressure chamber 402 will be sucked into the through opening 403. When the door is opened, the door panel 3 moves backward under the action of external force, and the inside of the negative pressure chamber 402 is in a negative pressure state, which triggers the constant pressure one-way valve 5 that delivers gas into the negative pressure chamber 402. Under the action of the negative pressure state inside the negative pressure chamber 402, the external pressure squeezes the slider 506, causing the slider 506 to approach the output end baffle 504 and leak out the vent groove 503. Outside air enters the inside of the negative pressure chamber 402 through the vent groove 503, which facilitates the protrusion 202 to detach from the through opening 403, completing the separation operation between the edge of the door panel 3 and the door frame 1.

[0033] When the door panel 3 impacts the door frame 1 under external force, the protrusion 202 will first insert into the through opening 403. The tubular negative pressure sleeve 401 itself has a certain elastic deformation capability, which buffers and protects the door frame 1. At the moment of impact, the air between the elastic clamps 404 of the protrusion 202 is pushed into the negative pressure chamber 402. The tubular negative pressure sleeve 401 itself deforms. Since the gas inside the negative pressure chamber 402 can only overflow from the constant pressure one-way valve 5, the gas inside the negative pressure chamber 402 has a damping effect on the door panel 3, reducing the sound generated during the impact and ensuring a better noise reduction effect.

[0034] Working principle: When the door closes, the protrusion 202 is inserted into the through opening 403 under the action of external force. When the protrusion 202 slides between the elastic clamps 404, it pushes the air between the elastic clamps 404 into the negative pressure chamber 402, causing the air pressure inside the negative pressure chamber 402 to suddenly increase. This triggers the constant pressure check valve 5 for outputting gas. The air inside the negative pressure chamber 402 is squeezed into the corresponding fixed sleeve 501, pushing the slider 506 to move along the inner sleeve 502. When the spring 505 is compressed, the vent groove 503 inside the inner sleeve 502 is exposed, allowing the airflow inside the negative pressure chamber 402 to connect with the outside through the vent groove 503. The airflow inside the negative pressure chamber 402 overflows until the air pressure inside the negative pressure chamber 402 can no longer push up the slider 506. The slider 506 is reset under the action of the spring 505. At this time, the protrusion 202 is fixed under the action of friction and negative pressure inside the negative pressure chamber 402, thus completing the fixation of the door frame 1 and the door panel 3 and ensuring its sealing effect.

[0035] When the door is opened, the door panel 3 moves backward under the action of external force, and the inside of the negative pressure chamber 402 is in a negative pressure state, which triggers the constant pressure one-way valve 5 that delivers gas into the negative pressure chamber 402. Under the action of the negative pressure state inside the negative pressure chamber 402, the external pressure squeezes the slider 506, causing the slider 506 to approach the output end baffle 504 and leak out the vent groove 503. Outside air enters the inside of the negative pressure chamber 402 through the vent groove 503, which facilitates the protrusion 202 to detach from the through opening 403, completing the separation operation between the edge of the door panel 3 and the door frame 1.

[0036] When the door panel 3 impacts the door frame 1 under external force, the protrusion 202 will first insert into the through opening 403. The tubular negative pressure sleeve 401 itself has a certain elastic deformation capability, which buffers and protects the door frame 1. At the moment of impact, the air between the elastic clamps 404 of the protrusion 202 is pushed into the negative pressure chamber 402. The tubular negative pressure sleeve 401 itself deforms. Since the gas inside the negative pressure chamber 402 can only overflow from the constant pressure one-way valve 5, the gas inside the negative pressure chamber 402 has a damping effect on the door panel 3, reducing the sound generated during the impact and ensuring a better noise reduction effect.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
