Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building doors and windows, and specifically relates to a door and window installation sealing structure. Background Technique
[0002] In construction projects, doors and windows, as an important part of a building, their installation quality directly affects the core performances of the building such as heat preservation, sound insulation, and waterproofing. However, there are many insurmountable defects in the current traditional door and window installation sealing methods: The traditional structure has a relatively single sealing design, mostly relying on a single sealing strip or sealant, lacking multiple protection designs, resulting in obvious short boards in the sealing performance, being difficult to effectively block the intrusion of dust and water vapor, and unable to form a comprehensive and reliable sealing effect; at the same time, the traditional structure performs poorly in dealing with various variables during installation and use. Due to the lack of an effective adaptive adjustment mechanism, in the face of uneven gaps during installation, minor deviations in the door and window frame size, and deformations caused by temperature changes during later use, etc., it often cannot be well adapted, and local loosening is likely to occur, thus leading to sealing failure. Summary of the Invention
[0003] To solve the problems in the background technique, the utility model provides a door and window installation sealing structure.
[0004] To achieve the above object, the utility model adopts the following technical solution: A door and window installation sealing structure includes a 'C'-shaped plate, a rubber pad, two sealing mechanisms, and multiple top-supporting mechanisms;
[0005] The inner bottom surface of the 'C'-shaped plate is provided with a rubber pad, and two sealing mechanisms are provided on both inner walls of the 'C'-shaped plate. A plurality of top-supporting mechanisms are provided between each sealing mechanism and the rubber pad, and the multiple top-supporting mechanisms on the same side are arranged in parallel and evenly distributed along the length direction of the 'C'-shaped plate.
[0006] Each sealing mechanism includes a sealing plate, a sealing strip, and two sealing units;
[0007] The outer wall of the sealing plate is hinged to the inner wall of the 'C'-shaped plate. A sealing strip is provided on the inner wall of the sealing plate. Two grooves are provided on the inner wall of the sealing plate along the length direction, and the two grooves are located below the sealing strip. Each groove is provided with a sealing unit.
[0008] Each sealing unit includes a shock-absorbing cotton, a triangular plate strip, and a sealing strip;
[0009] The shock-absorbing cotton is fixed in the corresponding groove on the sealing plate, and the shock-absorbing cotton is used in cooperation with the flat end of the triangular plate strip. One end of the triangular plate strip is hinged to the inner wall of the corresponding groove, and a plurality of sealing strips are evenly distributed on the inclined surface end of the triangular plate strip from top to bottom.
[0010] Each of the abutting mechanisms includes a fixing column, a sleeve, a spring and an inclined splint;
[0011] One end of the fixing column is fixedly connected to the inner wall of the corresponding "U-shaped" plate, the other end of the fixing column is fixedly connected to one end of the spring, one end of the sleeve is slidably sleeved on the fixing column, the other end of the sleeve is fixedly connected to the inclined splint, and the other end of the spring is fixedly connected to the inclined splint.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. Excellent sealing performance: Adopting a "progressive sealing" design, a first sealing barrier is formed by a sealing strip to block the initial intrusion of external dust and water vapor; the sealing strip cooperates with the triangular strip and the shock-absorbing cotton to form a second layer of sealing, and the "lever effect + elastic reverse push" is used to dynamically enhance the sealing pressure, further blocking the penetration of water vapor and air; the rubber pad at the bottom forms a third layer of sealing, tightly filling the bottom gap; the triple sealing works together to form a "three-dimensional sealing network", effectively solving the problem that the traditional single sealing structure is prone to failure due to gap changes, and significantly improving the reliability and comprehensiveness of sealing.
[0014] 2. Firm and flexible fixation: The abutting mechanism provides a lateral clamping force for the door and window frame through the elastic reaction force of the spring. Multiple abutting mechanisms are evenly distributed to ensure uniform stress on the peripheral wall of the door and window frame, avoiding local loosening and achieving firm fixation; at the same time, the elastic telescopic characteristic of the spring can adapt to the slight deviation of the size of the door and window frame, forming a "flexible fixation", which not only ensures the clamping firmness but also avoids deformation of the door and window frame caused by rigid extrusion, reducing stress damage caused by temperature changes or vibrations.
[0015] 3. Strong adaptability: The elastic adaptive design enables the device to well adapt to the size error of the door and window frame, the slight deviation during the installation process, and the temperature deformation during the later use; the deformation of elastic components such as the sealing strip, the sealing strip, the shock-absorbing cotton, the spring and the rubber pad can dynamically fill various gaps and deviations, improving the versatility and adaptability of the structure.
[0016] 4. Stable and durable structure: The rigid frame of the "U-shaped" plate provides a solid support for all components. The ring structure formed by the insertion of four "U-shaped" plates ensures the integrity of the overall enclosure. After being embedded in the preset groove, a stable nested relationship is formed with the wall and the door and window frame, avoiding loosening during long-term use; the rubber pad is made of high-elastic wear-resistant rubber, which can buffer the gravity pressure, reduce hard contact wear, and extend the service life of the structure.
[0017] 5. Convenient and efficient construction: The installation process of the entire structure follows a progressive logic of "contact - fitting - pressurization - fixation - closure". Each component works in coordination, making the installation process simple and easy. At the same time, the structure has strong adaptability to installation accuracy, reducing the construction difficulty and taking into account both the convenience of construction and the stability of the final installation effect.
[0018] In summary, through the collaborative mechanism of "progressive sealing + elastic adaptive fixation", the present utility model has achieved comprehensive optimization in aspects such as sealing performance, fixation effect, adaptive ability, structural durability, and construction convenience, effectively overcoming many defects of traditional door and window installation sealing structures, providing an efficient, reliable, and practical solution for door and window installation, and having high promotion value and application prospects.

[0024] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.
[0025] This embodiment describes a door and window installation sealing structure, including a 'C'-shaped plate 1, a rubber pad 2, two sealing mechanisms, and multiple top - supporting mechanisms;
[0026] A rubber pad 2 is provided on the inner bottom surface of the 'C'-shaped plate 1, and sealing mechanisms are provided on both inner side walls of the 'C'-shaped plate 1. A plurality of top - supporting mechanisms are provided between each sealing mechanism and the rubber pad 2, and the plurality of top - supporting mechanisms on the same side are arranged side by side and evenly distributed along the length direction of the 'C'-shaped plate 1.
[0027] Each of the sealing mechanisms includes a sealing plate 3, a sealing belt 4 and two sealing units;
[0028] The outer wall of the sealing plate 3 is hinged to the inner wall of the 'U'-shaped plate 1. A sealing belt 4 is provided on the inner wall of the sealing plate 3. Two grooves are provided on the inner wall of the sealing plate 3 along the length direction. The two grooves are located below the sealing belt 4. A sealing unit is provided in each groove.
[0029] Each of the sealing units includes a shock-absorbing cotton 9, a triangular plate strip 10 and a sealing strip 11;
[0030] The shock-absorbing cotton 9 is fixed in the corresponding groove on the sealing plate 3. The shock-absorbing cotton 9 is used in cooperation with the flat end of the triangular plate strip 10. One end of the triangular plate strip 10 is hinged to the inner wall of the corresponding groove. A plurality of sealing strips 11 are evenly arranged on the inclined surface end of the triangular plate strip 10 from top to bottom.
[0031] Each of the top-supporting mechanisms includes a fixed column 5, a sleeve 6, a spring 7 and an inclined clamping plate 8;
[0032] One end of the fixed column 5 is fixedly connected to the inner wall of the corresponding 'U'-shaped plate 1. The other end of the fixed column 5 is fixedly connected to one end of the spring 7. One end of the sleeve 6 is slidably sleeved on the fixed column 5. The other end of the sleeve 6 is fixedly connected to the inclined clamping plate 8. The other end of the spring 7 is fixedly connected to the inclined clamping plate 8.
[0033] The working principle of the door and window installation sealing structure of the utility model is centered around the collaborative mechanism of "progressive sealing + elastic adaptive fixing". Before installation, a groove matching the device needs to be excavated at the preset installation position of the door and window frame, and its dimensional accuracy should be adapted to the outer contour of the 'J'-shaped plate 1 to ensure that the four 'J'-shaped plates 1 form a stable ring-shaped surrounding structure after being inserted around the door and window frame. The rigid frame of the 'J'-shaped plate 1 (such as made of metal or high-strength plastic) provides the basic support and a stable carrier for the subsequent sealing and fixing components. When the door and window frame starts to enter the area surrounded by the 'J'-shaped plate 1, it first contacts the sealing plate 3. The sealing plate 3 is connected to the inner wall of the 'J'-shaped plate 1 through a hinge structure and can rotate slightly with the thrust of the door and window frame. The sealing strip 4 on its inner wall (preferably made of elastic rubber) first contacts the outer wall of the door and window frame. As the door and window frame continues to penetrate, the sealing plate 3 is gradually pressed against the door and window frame. The sealing strip 4 deforms due to its own elasticity and tightly wraps the surface of the door and window frame, forming the first sealing barrier. By the elastic deformation of the sealing strip 4, the initial gap between the door and window frame and the sealing plate 3 is filled, which can block the initial intrusion of external dust and water vapor. When the door and window frame further penetrates, its outer wall contacts the sealing strip 11 in the groove of the sealing plate 3. The sealing strip 11 is distributed in multiple segments on the inclined surface of the triangular plate strip 10. The elasticity of the material of the sealing strip 11 is better than that of the sealing strip 4 (such as foamed rubber), which can adapt to more subtle surface unevenness. As the door and window frame advances, its outer wall pushes the triangular plate strip 10 to rotate around the hinge point, making the flat end of the triangular plate strip 10 gradually press against the shock-absorbing cotton 9 (made of high-density elastic cotton) in the groove. At this time, due to the increase in the rotation angle of the inclined surface of the triangular plate strip 10, the contact pressure between the sealing strip 11 and the door and window frame increases synchronously (similar to the "wedging" effect). At the same time, the shock-absorbing cotton 9 generates a reaction force after being compressed and reversely presses on the sealing strip 11 through the triangular plate strip 10, making it fit more tightly against the door and window frame, forming the second layer of sealing. The dynamic enhancement of the sealing pressure is achieved by using the "lever effect of the triangular plate strip 10 + elastic reverse push of the shock-absorbing cotton 9", which is tighter than the first layer of sealing and further blocks the penetration of water vapor and air. When the door and window frame continues to penetrate, it will contact the inclined clamping plate 8 of the top support mechanism. The inclined surface design of the inclined clamping plate 8 can convert the longitudinal thrust of the door and window frame into a lateral force, pushing the sleeve 6 to slide along the fixed column 5. At this time, the spring 7 is compressed and stores elastic potential energy. The reaction force of the spring 7 is transmitted to the door and window frame through the inclined clamping plate 8, forming a lateral clamping force on the door and window frame. Since multiple top support mechanisms are evenly distributed along the length direction of the 'J'-shaped plate 1, it ensures that the peripheral wall of the door and window frame is evenly stressed, avoiding local loosening. At the same time, the elastic telescopic property of the spring 7 can adapt to the slight deviation of the door and window frame size (such as ±1 - 2 mm), which not only ensures the clamping stability but also avoids deformation of the door and window frame caused by rigid extrusion, realizing the "flexible fixing" of the door and window frame, providing sufficient clamping force while reserving a certain buffer space to reduce the stress damage of the door and window frame caused by temperature changes or vibrations.Once the door and window frame is fully inserted into the device, its bottom contacts the rubber pad 2 (highly elastic and wear-resistant rubber) on the inner bottom surface of the 'U'-shaped plate 1. The rubber pad 2 deforms under pressure, tightly filling the gap between the bottom of the door and window frame and the 'U'-shaped plate 1, forming a third (bottom) seal. Simultaneously, the elasticity of the rubber pad 2 buffers the weight pressure of the door and window frame, preventing wear caused by hard contact. At this point, the four 'U'-shaped plates 1 interlock to form a complete ring structure, comprehensively wrapping the perimeter of the door and window frame from the top, sides, and bottom. The sealing strip 4, sealing bar 11, and rubber pad 2 form a "three-dimensional sealing network." The top-mounted mechanism provides uniform elastic clamping in the circumference, achieving a double closed loop of "sealing + fixing." The component-coordinated sealing solves the problem of traditional single sealing structures being prone to failure due to gap changes. The elastic adaptive design allows the device to adapt to the size errors of door and window frames, slight offsets during installation, and temperature deformation during later use. The rigid frame of the 'U'-shaped plate 1 provides support for all components, and the interlocking ring structure ensures the integrity of the overall enclosure. After finally being embedded in the preset groove, the device forms a stable nesting relationship with the wall and door and window frames, avoiding loosening during long-term use. Through the progressive process of "contact-fitting-pressurizing-fixing-closing", combined with the adaptive characteristics of the elastic components, efficient sealing and reliable fixing of door and window frame installation are achieved, taking into account both construction convenience and long-term stability.
