Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, and particularly relates to a sun-resistant sealing strip. Background Art

[0002] In many fields, the sealing strip plays a crucial sealing role. However, there are some problems in the actual use of the existing sealing strips.

[0003] Traditional sealing strips often have insufficient sun resistance, are prone to aging and cracking under long-term sunlight irradiation, resulting in a decline in sealing performance; at the same time, their strength and stability may not be ideal, and they are prone to deformation or damage under external force; in addition, the weight of traditional sealing strips may be relatively large, and installation and replacement are also relatively inconvenient.

[0004] Therefore, we propose a sun-resistant sealing strip. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a sun-resistant sealing strip to prevent the problems of aging, cracking and decline of sealing performance of the sealing strip under long-term sunlight irradiation; to prevent the problems of insufficient strength and stability of the sealing strip, deformation or damage under external force; to prevent the problems of relatively large weight of the sealing strip, inconvenient installation and replacement, so as to improve the sun resistance, strength and stability of the sealing strip, as well as the convenience of installation and replacement, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A sun-resistant sealing strip includes a sealing strip body and a connecting strip. The sealing strip body is inserted into the connecting strip. A plurality of first installation grooves are arranged at equal distances at the top end of the sealing strip body. A first installation strip is slidably connected in the first installation groove. A protective strip is fixedly connected to the top end of the first installation strip away from the first installation groove;

[0008] A fiber layer is arranged inside the sealing strip body, and a plurality of uniformly distributed triangular holes are arranged inside the sealing strip body and located inside the fiber layer.

[0009] By adopting the above technical solution, the sealing strip body, as the main sealing component, can be conveniently installed at the position to be sealed through the insertion connection with the connecting strip. When the sealing strip body is extruded, its own elastic material will deform to fill the sealing gap, so as to achieve the sealing function and prevent air, water, dust, etc. from entering the sealed area;

[0010] The protective strip is located at the top of the sealing strip body and plays an additional protective role. It can block the direct impact of external factors such as direct sunlight, rain washing, and dust accumulation on the sealing strip body, extend the service life of the sealing strip. The protective strip is slidably connected to the first installation groove on the sealing strip body through the first installation strip. This connection method not only facilitates the installation and replacement of the protective strip but also ensures that the protective strip maintains a stable position during use;

[0011] The presence of the fiber layer enhances the strength and stability of the sealing strip body. The fiber material has high tensile strength and wear resistance, which can prevent the sealing strip from deforming or being damaged due to external forces during long-term use. At the same time, the fiber layer can also improve the weather resistance of the sealing strip, enabling it to maintain good performance under different temperature, humidity, and light conditions;

[0012] The triangular holes reduce the material usage amount and the overall weight of the sealing strip without affecting its performance. When the sealing strip is squeezed, the triangular holes can provide a certain deformation space, making it easier for the sealing strip to adapt to different-shaped sealing surfaces and improving the sealing effect. To a certain extent, the triangular holes contribute to the heat dissipation and ventilation inside the sealing strip, preventing the sealing strip from aging or its performance from deteriorating due to long-term heating.

[0013] Furthermore, the sealing strip body is made of ethylene propylene diene monomer (EPDM) rubber.

[0014] By adopting the above technical solution, the EPDM rubber material is soft and elastic. When the sealing strip body is installed at the sealing part, it will deform under extrusion and closely adhere to the sealing interface. This elastic deformation enables the sealing strip to fill the sealing gap and prevent the entry of substances such as air, water, and dust, thereby achieving the sealing function. Due to its good elasticity, the sealing strip can adapt to various irregular sealing surface shapes, ensuring good sealing effects in different application scenarios. In window and door sealing, it can adapt to the complex shapes between the window frame and the window sash to achieve full-range sealing;

[0015] EPDM rubber itself has good anti-ultraviolet performance. Under sunlight irradiation, it can effectively block the erosion of ultraviolet rays and reduce problems such as material aging and degradation caused by ultraviolet rays. This enables the sealing strip to still maintain its physical properties and sealing function when exposed to sunlight for a long time. Sunlight irradiation will increase the surface temperature of the sealing strip, but EPDM rubber can withstand this temperature change without obvious softening, deformation, or performance decline, which helps to maintain the shape and sealing effect of the sealing strip and ensures normal operation in high-temperature environments.

[0016] Furthermore, the protective strip is made of polypropylene.

[0017] By adopting the above technical solution, the polypropylene protective strip is located at the top of the sealing strip body, which can directly block most of the sunlight from shining directly on the sealing strip body. Ultraviolet rays in sunlight are one of the main factors causing rubber aging. The presence of the protective strip reduces the irradiation of ultraviolet rays on the ethylene propylene diene monomer (EPDM) rubber sealing strip body, thereby delaying the aging process of the sealing strip; during daily use, the sealing strip may be subject to mechanical damages such as scratching and collision. The polypropylene protective strip is relatively tough and can provide a layer of physical protection for the sealing strip body to prevent the sealing strip from being damaged by external mechanical forces. During the process of opening and closing the doors and windows, the protective strip can prevent the sealing strip from directly rubbing against the window frame or other objects, reducing wear and tear;

[0018] Polypropylene has certain heat resistance. Under sunlight irradiation, the surface temperature of the sealing strip will rise, but the polypropylene protective strip can maintain its shape and performance stability within a certain temperature range and will not easily soften or deform, which helps to maintain the protective effect of the protective strip on the sealing strip body and can effectively block sunlight and heat even in high-temperature environments; at the same time, polypropylene is not easily embrittled in low-temperature environments. Under different climate conditions, whether it is a hot summer or a cold winter, the protective strip can maintain good performance and provide continuous protection for the sealing strip;

[0019] Polypropylene has certain tolerance to various chemical substances such as acids, alkalis, and salts. In the outdoor environment, it may come into contact with chemical substances such as rainwater and air pollutants. The polypropylene protective strip can resist the erosion of these chemical substances and ensure that it will not be damaged due to chemical action during long-term use; it has certain antioxidant properties and is not easily oxidized when exposed to air for a long time, which enables the protective strip to maintain its appearance and performance and extend its service life;

[0020] The protective strip made of polypropylene provides effective protection for the sunlight-resistant sealing strip through the functions of physical protection, weather resistance, and chemical stability, improving the overall performance and service life of the sealing strip.

[0021] Furthermore, the fiber layer is made of polyester fiber.

[0022] By adopting the above technical solution, polyester fiber has high strength. The fiber layer inside the sealing strip body can significantly improve the overall strength of the sealing strip. When the sealing strip is subjected to external force extrusion, stretching, or twisting, the fiber layer can bear part of the stress and prevent the sealing strip from easily deforming or being damaged, which enables the sealing strip to maintain good shape and sealing performance in various use environments; polyester fiber has good wear resistance, and the fiber layer can reduce the wear of the sealing strip during the contact and friction with the sealing surface. During the frequent opening and closing of doors and windows, the sealing strip constantly rubs against the window frame or door frame. The fiber layer can extend the service life of the sealing strip and ensure its long-term effective sealing function;

[0023] Under sunlight irradiation, the fiber layer can reduce the direct impact of ultraviolet rays on the ethylene propylene diene monomer rubber of the sealing strip body, and reduce the aging and degradation rate of the sealing strip caused by ultraviolet radiation. Compared with the sealing strip without a fiber layer, the sealing strip containing a polyester fiber layer is more resistant to long-term sunlight exposure; when the sealing strip is exposed to a high-temperature environment, the fiber layer can help maintain the structural stability of the sealing strip, preventing the sealing strip from softening, deforming or losing its sealing performance due to high temperature; at the same time, in an environment with large temperature changes, the fiber layer can also reduce the stress generated by the thermal expansion and contraction of the sealing strip, improving the durability of the sealing strip; in a humid, dusty and chemically active environment, the fiber layer can provide additional protection for the sealing strip, making it less vulnerable to external factors, thus extending the service life of the sealing strip;

[0024] When the sealing strip is affected by factors such as temperature, humidity and pressure, the fiber layer can play a restraining role, preventing the sealing strip from expanding or contracting excessively, ensuring that the sealing strip always maintains a good fit with the sealing surface, and maintaining the stability of the sealing effect;

[0025] The fiber layer made of polyester fiber plays an important role in enhancing the mechanical properties, improving the weather resistance and ensuring the dimensional stability of the sunlight-resistant sealing strip, providing strong support for the reliable sealing and long-term use of the sealing strip.

[0026] Furthermore, a second mounting strip is fixedly connected to the bottom end of the sealing strip body.

[0027] By adopting the above technical solution, the second mounting strip can be inserted into the mounting groove to achieve the rapid and accurate installation of the sealing strip. This installation method is simple and convenient, improving the installation efficiency and reducing the installation time and labor costs; the second mounting strip is fixedly connected to the sealing strip body, making the sealing strip more stable after installation. When the sealing strip is subjected to external forces, such as pressure, vibration or impact on the sealing surface, the second mounting strip can help disperse these forces, preventing the sealing strip from easily shifting or falling off, ensuring that the sealing strip always remains in the correct position during long-term use and playing a reliable sealing role;

[0028] In some installation structures, the second mounting strip can closely cooperate with the installation part, increasing the contact pressure between the sealing strip body and the sealing surface. When the sealing strip is squeezed, the second mounting strip can provide additional supporting force, enabling the sealing strip to better fit the sealing surface and improving the sealing performance; the second mounting strip can form a barrier between the sealing strip and the installation part, reducing possible leakage paths. In the sealing of doors and windows, the second mounting strip can prevent air, water or dust from penetrating through the gap between the sealing strip and the window frame, further enhancing the sealing effect.

[0029] Furthermore, a second installation groove for installing the second installation strip is formed inside the connection strip, and the second installation strip is connected to the second installation groove.

[0030] By adopting the above technical solutions, the second installation groove in the connection strip provides an accurate installation position for the second installation strip at the bottom end of the sealing strip body, realizing rapid positioning and firm connection, preventing the sealing strip from shifting or falling off during use; the combination of the two reduces the sealing interface gap, prevents the penetration of substances, and at the same time makes the pressure evenly distributed, enhancing the compressive capacity of the sealing strip and improving the sealing performance; it is convenient to replace the sealing strip, improves the maintenance efficiency, and has universality, being applicable to sealing strips and connection strips of different types and sizes, and is widely used in various scenarios.

[0031] Compared with the prior art, the utility model has the following beneficial effects:

[0032] (1) For the sun-resistant sealing strip of the utility model, the protective strip is located at the top end of the sealing strip body, which can effectively block direct sunlight, reduce the erosion of ultraviolet rays on the sealing strip body, and delay the aging process of the sealing strip; the protective strip is connected in a sliding manner, which is convenient for installation and replacement, and ensures stability during use.

[0033] (2) For the sun-resistant sealing strip of the utility model, the setting of the fiber layer enhances the strength of the sealing strip body, making it not easy to deform or be damaged when subjected to external force extrusion, stretching or twisting, and also improves the weather resistance of the sealing strip, enabling it to maintain good performance under different environmental conditions.

[0034] (3) For the sun-resistant sealing strip of the utility model, the design of the triangular holes reduces the weight of the sealing strip without affecting the performance, reducing the material cost; it also provides a deformation space for the sealing strip, making it easier to adapt to sealing surfaces of different shapes and improving the sealing effect; at the same time, it helps with heat dissipation and ventilation inside the sealing strip, preventing aging or performance degradation due to long-term heating.

[0039] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0040] In order to prevent problems such as the sealing strip aging, cracking under long-term sunlight irradiation, and the sealing performance decreasing; preventing problems such as the insufficient strength and stability of the sealing strip, deforming or being damaged under external force; preventing problems such as the relatively large weight of the sealing strip, which is inconvenient for installation and replacement, so as to improve the sun exposure resistance, strength and stability of the sealing strip, as well as the convenience of installation and replacement, as Figure 1 、 Figure 2 、 Figure 3 shown, a sun exposure resistant sealing strip includes a sealing strip body 1 and a connecting strip 9. The sealing strip body 1 is inserted into the connecting strip 9. A plurality of first installation grooves 2 arranged at equal distances are opened at the top end of the sealing strip body 1. A first installation strip 3 is slidably connected in the first installation groove 2. The top end of the first installation strip 3 away from the first installation groove 2 is fixedly connected with a protection strip 4;

[0041] A fiber layer 5 is arranged inside the sealing strip body 1, and a plurality of uniformly distributed triangular holes 6 are opened inside the sealing strip body 1 and located inside the fiber layer 5.

[0042] During use, the sealing strip body 1 serves as the main sealing component. Through the insertion connection with the connecting strip 9, it can be conveniently installed at the position that needs to be sealed. When the sealing strip body 1 is squeezed, its own elastic material will deform and fill the sealing gap, thereby realizing the sealing function and preventing air, water, dust, etc. from entering the sealed area;

[0043] The protection strip 4 is located at the top end of the sealing strip body 1 and plays an additional protection role. It can block the direct influence of external factors such as direct sunlight, rain washing, and dust accumulation on the sealing strip body 1, and extend the service life of the sealing strip. The protection strip 4 is slidably connected with the first installation groove 2 on the sealing strip body 1 through the first installation strip 3. This connection method not only facilitates the installation and replacement of the protection strip 4, but also ensures that the protection strip 4 maintains a stable position during use;

[0044] The presence of the fiber layer 5 enhances the strength and stability of the sealing strip body 1. The fiber material has relatively high tensile strength and wear resistance, which can prevent the sealing strip from deforming or being damaged due to external force during long-term use; at the same time, the fiber layer 5 can also improve the weather resistance of the sealing strip, so that it maintains good performance under different temperature, humidity and light conditions;

[0045] The triangular holes 6 reduce the material usage and the overall weight of the sealing strip without affecting the performance of the sealing strip. When the sealing strip is squeezed, the triangular holes 6 can provide a certain deformation space, making it easier for the sealing strip to adapt to sealing surfaces of different shapes and improving the sealing effect. To a certain extent, the triangular holes 6 contribute to heat dissipation and ventilation inside the sealing strip, preventing the sealing strip from aging or its performance from deteriorating due to long-term heat exposure.

[0046] Exemplarily, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the present utility model further includes that the sealing strip body 1 is made of ethylene propylene diene monomer (EPDM) rubber.

[0047] When in use, the EPDM rubber is soft and elastic. When the sealing strip body 1 is installed at the sealing position, it will deform under extrusion and closely adhere to the sealing interface. This elastic deformation enables the sealing strip to fill the sealing gap and prevent substances such as air, water, and dust from entering, thereby achieving the sealing function. Due to its good elasticity, the sealing strip can adapt to various irregular sealing surface shapes, ensuring good sealing effects in different application scenarios. In the sealing of doors and windows, it can adapt to the complex shapes between the window frame and the window sash to achieve all-round sealing.

[0048] EPDM rubber itself has good anti-ultraviolet performance. Under sunlight irradiation, it can effectively block the erosion of ultraviolet rays and reduce problems such as material aging and degradation caused by ultraviolet rays. This enables the sealing strip to maintain its physical properties and sealing function when exposed to sunlight for a long time. Although sunlight irradiation will increase the surface temperature of the sealing strip, EPDM rubber can withstand this temperature change without obvious softening, deformation, or performance degradation, which helps to maintain the shape and sealing effect of the sealing strip and ensures normal operation in high-temperature environments.

[0049] Exemplarily, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the present utility model further includes that the protective strip 4 is made of polypropylene.

[0050] When in use, the polypropylene protective strip 4 is located at the top of the sealing strip body and can directly block most of the sunlight from directly irradiating on the sealing strip body. Ultraviolet rays in sunlight are one of the main factors causing rubber aging. The presence of the protective strip 4 reduces the irradiation of ultraviolet rays on the EPDM rubber sealing strip body 1, thereby delaying the aging process of the sealing strip. In daily use, the sealing strip may be subject to mechanical damages such as scratching and collision. The polypropylene protective strip 4 is relatively tough and can provide a layer of physical protection for the sealing strip body to prevent the sealing strip from being damaged by external mechanical forces. During the opening and closing of doors and windows, the protective strip 4 can prevent the sealing strip from directly rubbing against the window frame or other objects, reducing wear.

[0051] Polypropylene has certain heat resistance. Under sunlight irradiation, the surface temperature of the sealing strip will rise. However, the polypropylene protective strip can maintain its shape and performance stability within a certain temperature range and will not easily soften or deform. This helps to maintain the protective effect of the protective strip on the sealing strip body and can effectively block sunlight and heat even in high-temperature environments. At the same time, polypropylene is not easily embrittled in low-temperature environments. Under different climatic conditions, whether it is a hot summer or a cold winter, the protective strip can maintain good performance and provide continuous protection for the sealing strip.

[0052] Polypropylene has certain tolerance to various chemical substances such as acids, alkalis, and salts. In the outdoor environment, it may come into contact with chemical substances such as rainwater and air pollutants. The polypropylene protective strip can resist the erosion of these chemical substances and ensure that it will not be damaged due to chemical action during long-term use. It has certain antioxidant properties and is not easily oxidized when exposed to air for a long time. This enables the protective strip 4 to maintain its appearance and performance and extend its service life.

[0053] The protective strip 4 made of polypropylene provides effective protection for the sunlight-resistant sealing strip through physical protection, weather resistance, and chemical stability, etc., improving the overall performance and service life of the sealing strip.

[0054] Exemplarily, as Figure 3 shown, the present utility model further includes that the fiber layer 5 is made of polyester fiber.

[0055] During use, polyester fiber has high strength. The fiber layer 5 inside the sealing strip body 1 can significantly improve the overall strength of the sealing strip. When the sealing strip is subjected to external force extrusion, stretching, or twisting, the fiber layer 5 can bear part of the stress and prevent the sealing strip from being easily deformed or damaged. This enables the sealing strip to maintain good shape and sealing performance in various use environments. Polyester fiber has good wear resistance. The fiber layer 5 can reduce the wear of the sealing strip during the contact and friction with the sealing surface. During the frequent opening and closing of doors and windows, the sealing strip constantly rubs against the window frame or door frame. The fiber layer 5 can extend the service life of the sealing strip and ensure its long-term effective sealing function.

[0056] Under sunlight irradiation, the fiber layer 5 can reduce the direct impact of ultraviolet rays on the ethylene propylene diene monomer rubber of the sealing strip body 1, and reduce the aging and degradation rate of the sealing strip due to ultraviolet radiation. Compared with the sealing strip without the fiber layer 5, the sealing strip containing the polyester fiber layer is more resistant to long-term sunlight exposure; when the sealing strip is exposed to a high-temperature environment, the fiber layer can help maintain the structural stability of the sealing strip, prevent the sealing strip from softening, deforming or losing its sealing performance due to high temperature; at the same time, in an environment with large temperature changes, the fiber layer 5 can also reduce the stress generated by the sealing strip due to thermal expansion and contraction, and improve the durability of the sealing strip; in a humid, dusty and chemically active environment, the fiber layer 5 can provide additional protection for the sealing strip, making it less vulnerable to external factors, thereby extending the service life of the sealing strip;

[0057] When the sealing strip is affected by factors such as temperature, humidity and pressure, the fiber layer 5 can play a restraining role, preventing the sealing strip from expanding or contracting excessively, ensuring that the sealing strip always maintains good contact with the sealing surface, and maintaining the stability of the sealing effect;

[0058] The fiber layer 5 made of polyester fiber plays an important role in the sun-resistant sealing strip by enhancing mechanical properties, improving weather resistance and ensuring dimensional stability, providing strong support for the reliable sealing and long-term use of the sealing strip.

[0059] Exemplarily, as Figure 2 、 Figure 3 shown, the present invention further includes that a second installation strip 7 is fixedly connected to the bottom end of the sealing strip body 1.

[0060] During use, the second installation strip 7 can be inserted into the installation groove to achieve quick and accurate installation of the sealing strip. This installation method is simple and convenient, improving the installation efficiency and reducing the installation time and labor costs; the second installation strip 7 is fixedly connected to the sealing strip body, making the sealing strip more stable after installation. When the sealing strip is subjected to external forces, such as pressure, vibration or impact on the sealing surface, the second installation strip 7 can help disperse these forces, prevent the sealing strip from easily shifting or falling off, and ensure that the sealing strip always remains in the correct position during long-term use and plays a reliable sealing role;

[0061] In some installation structures, the second installation strip 7 can be closely fitted with the installation part to increase the contact pressure between the sealing strip body 1 and the sealing surface. When the sealing strip is squeezed, the second installation strip 7 can provide additional supporting force to make the sealing strip better fit the sealing surface and improve the sealing performance; the second installation strip 7 can form a barrier between the sealing strip and the installation part to reduce possible leakage paths. In window and door sealing, the second installation strip can prevent air, water or dust from penetrating through the gap between the sealing strip and the window frame, further enhancing the sealing effect.

[0062] Exemplarily, as Figure 1 , Figure 2 , Figure 3 shown, the utility model further includes that a second installation groove 8 for installing the second installation strip 7 is formed inside the connection strip 9, and the second installation strip 7 is connected to the second installation groove 8.

[0063] During use, the second installation groove in the connection strip provides an accurate installation position for the second installation strip at the bottom end of the sealing strip body, realizing quick positioning and firm connection, preventing the sealing strip from shifting or falling off during use; the combination of the two reduces the sealing interface gap, prevents the penetration of substances, and at the same time makes the pressure evenly distributed, enhancing the compressive capacity of the sealing strip and improving the sealing performance; it is convenient to replace the sealing strip, improves the maintenance efficiency, and has universality, being applicable to different types and sizes of sealing strips and connection strips, and is widely used in various scenarios.

[0064] It should be noted that the utility model is a sun-resistant sealing strip. The protective strip 4 is inserted into the first installation groove 2 at the top end of the sealing strip body 1 through the first installation strip 3 to ensure that the protective strip 4 is firmly installed and will not easily fall off during use; the second installation strip 7 at the bottom end of the sealing strip body 1 is inserted into the second installation groove 8 inside the connection strip 9 to ensure that the second installation strip 7 is tightly connected to the second installation groove 9, providing a stable installation position for the sealing strip.
