Description

Technical Field

[0001] This utility model belongs to the field of windproof curtain technology, specifically relating to a high-resilience noise-reducing windproof curtain side rail system. Background Technology

[0002] The side rail system of the windproof curtain is the core guiding and positioning component of the windproof curtain. It mainly forms precise constraints on the left and right sides of the curtain. On the one hand, it limits the horizontal deviation of the curtain to ensure windproof sealing. On the other hand, it provides a smooth vertical guiding channel to help the curtain rise and fall and slide stably. It is suitable for windproof needs in scenarios such as warehousing and building facades. It has a compact structure and is suitable for curtains of different widths.

[0003] In current mainstream windproof curtain side rail systems, the positioning and constraint of the curtain side edges mostly adopt... Figure 14 The sponge strip is fixed by adhesive as shown, or Figure 15 The diagram illustrates two positioning methods for the adhesive strip. The sponge strip adhesive method is prone to adhesive failure and detachment during long-term use, causing the sponge strip to detach from the side rail simultaneously with the fabric edge, thus losing its positioning function. The adhesive strip positioning method relies solely on the elastic force generated by the elastic deformation of the adhesive strip itself for the fabric's rebound and smoothing effect. However, long-term exposure to environmental factors such as temperature, humidity, and light can cause the adhesive strip to experience elasticity decay and deterioration in its aging resistance, directly leading to a decrease in the fabric's rebound and smoothing effect. In summary, both existing fabric side edge positioning methods have significant performance limitations in practical applications. Utility Model Content

[0004] To address the problem of adhesive failure and detachment in existing sponge strip bonding solutions during long-term use, which causes the sponge strip to detach from the side rail simultaneously with the side edge of the curtain, resulting in loss of positioning function, this invention provides a high-resilience, noise-reducing windproof curtain side rail system. In this invention, the low-friction noise characteristic improves the quietness of the equipment during operation, making it particularly suitable for noise-sensitive environments such as residences and offices. Simultaneously, it reduces the lifespan issue caused by direct friction between the traditional adhesive strip and the inner wall of the side rail system, lowering the frequency of component replacement. Furthermore, the consistently stable and tight tensile performance further ensures that the curtain is less prone to loosening or shifting during long-term use, maintaining excellent windproof and sun-shading core functions. The specific technical solution is as follows: A high-resilience, noise-reducing, windproof curtain side rail system includes a first frame and a second frame. The semi-enclosed cavity formed by the first and second frames also includes a side rail assembly. The side rail assembly is slidably embedded within the semi-enclosed cavity. Multiple sets of curtain positioning assemblies are arranged between the side rail assembly and the semi-enclosed cavity. Each set of curtain positioning assemblies includes: a T-shaped slider, a mounting strip, a hollow cavity, a leaf spring, a protrusion, and a hemispherical end. The T-shaped slider is vertically positioned within the side rail assembly cavity. The mounting strip is positioned on the side wall of the T-shaped slider, forming an integral structure with it. The hollow cavity extends vertically through the mounting strip. Two sets of leaf springs are symmetrically inserted into the upper and lower ends of the hollow cavity. The protrusion is positioned on the outer wall of the leaf spring. The hemispherical end is positioned on the outer wall of the protrusion facing away from the leaf spring, and the outer wall of the hemispherical end is hemispherical.

[0005] In the above technical solution, the side rail assembly includes: a side rail, a curtain positioning strip, and a T-shaped groove. The side rail is embedded vertically within the cavity of the semi-enclosed structure. The curtain positioning strip is vertically positioned in the middle of the side rail and is located on the side of the side rail away from the cavity of the semi-enclosed structure. Two sets of T-shaped grooves are provided, symmetrically positioned vertically on both sides of the side rail and located on the side of the side rail away from the cavity of the semi-enclosed structure.

[0006] In the above technical solution, the curtain positioning components located in the inner cavities of the two sets of T-shaped slide grooves are arranged in an alternating manner.

[0007] In the above technical solution, the T-shaped slider is slidably embedded in the inner cavity of the T-shaped groove, and the T-shaped cross-section of the T-shaped slider is adapted to the inner cavity of the T-shaped cross-section of the T-shaped groove.

[0008] In the above technical solution, the leaf spring is V-shaped in its natural state, and the range between the initial included angle of the leaf spring and the minimum included angle under the maximum compression state is 60° to 0°.

[0009] In the above technical solution, the hemispherical end is attached to the inner sidewalls of the first frame and the second frame.

[0010] In the above technical solution, a plug is inserted into the top of the side rail.

[0011] In the above technical solution, the protrusion is configured as a solid cylindrical structure.

[0012] In the above technical solution, the protrusion is configured as a hollow columnar structure with openings on both sides.

[0013] The side rail system for a high-resilience, noise-reducing windproof curtain of this utility model has the following advantages compared with the prior art: I. Regarding the existing sponge strip adhesive solution used for the side rails of windproof curtains, long-term use is prone to adhesive failure due to adhesive aging, changes in environmental temperature and humidity, or frequent curtain movement. This leads to the sponge strip detaching from the side rail cavity simultaneously with the curtain edge, losing its positioning and constraint function on the curtain. This invention addresses this problem by using a synergistic design of T-shaped sliders, mounting strips, hollow cavities, leaf springs, and protrusions to construct a stable curtain positioning component within the side rail system that remains within the cavity. This component, through precise adaptation and limiting action between mechanical structures, replaces the traditional adhesive bonding method, fundamentally avoiding the risk of delamination caused by adhesive failure and completely eliminating the problem. The failure of the curtain fabric detaching from the side rail along with the sponge strip can be addressed in two ways. First, the stability of the mechanical positioning structure is far superior to that of the adhesive method, which can maintain reliable constraint on the side edge of the curtain fabric for a long time, ensuring that the curtain fabric remains within the preset positioning range during long-term use and avoiding problems such as curtain fabric displacement and wrinkles caused by positioning failure. Second, the stable positioning components enable the curtain fabric to have stronger resistance to deformation when facing external forces such as wind and human touch. It can not only withstand greater external impacts, but also quickly return to its initial state after being subjected to external forces, reducing the impact of external forces on the curtain fabric structure and performance, further extending the overall service life of the windproof curtain, and reducing the frequency and cost of maintenance caused by positioning failure. II. Regarding the existing rubber strip positioning schemes, where the fabric's rebound and smoothing function relies entirely on the elastic force generated by the rubber strip's own elastic deformation, and considering the long-term effects of temperature and humidity fluctuations, ultraviolet radiation, and other environmental factors, the rubber strip is prone to molecular chain degradation and cross-linking structure aging, leading to a decrease in elastic modulus and deterioration in aging resistance, ultimately causing a continuous decline in the fabric's rebound and smoothing effect. This invention addresses this technical defect by constructing a fabric positioning component through the collaborative use of a leaf spring, T-shaped sliding strip, mounting strip, hollow cavity, and protrusions. This overcomes the limitation of the traditional rubber strip's single elastic source, using the leaf spring as the core elastic force output component. Its elastic force coverage is far greater than the rubber strip's own elastic deformation range, and the leaf spring, through continuous and tight contact with the inner cavity of the side rail system, provides stable and durable elastic constraint for the fabric. Firstly, the leaf spring is made of a metallic elastic material, which is subjected to… The elastic decay rate affected by environmental factors is less than 1 / 5 of that of traditional rubber strips, which can maintain stable elastic output for a long time and avoid the decline in the rebound ability of the curtain due to elastic failure. Secondly, the mechanical cooperation structure of the leaf spring with T-shaped slide bar, mounting strip, hollow cavity and protrusion allows the elastic force to be evenly transmitted to the side edge of the curtain, realizing the uniform stretching of the entire curtain. Compared with the curtain wrinkling problem caused by uneven elasticity of rubber strip, it further improves the flatness of the curtain. Thirdly, by replacing the rubber strip with the leaf spring as the core rebound component, the dependence on the elastic performance of the rubber strip is greatly reduced. Even if the rubber strip deteriorates to a certain extent due to long-term use, it will not directly affect the rebound and stretching effect of the curtain. This significantly improves the long-term reliability and environmental adaptability of the side rail system and extends the maintenance cycle and service life of the overall device. Third, in this solution, a dual-optimized structure is formed through the continuous and tight contact between the leaf spring and the inner cavity of the side rail system, and the adaptive contact between the hemispherical outer wall of the hemispherical end and the inner walls of the first and second frame frames of the side rail body. Firstly, compared to the noise generated by the rigid friction between the traditional elastic element and the rail wall during repeated deformation and rebound, the tight contact of the leaf spring reduces unnecessary swaying of the elastic element, while the hemispherical outer wall of the hemispherical end transforms sliding contact into low-friction point contact, significantly reducing friction noise. Secondly, this structure can always maintain contact with the curtain fabric and... The stable constraint of the component side rail, curtain positioning strip, and T-shaped slide rail ensures that it remains tightly stretched within the cavity enclosed by the first and second frame sides; the low friction noise characteristics improve the quietness of the equipment during use, making it particularly suitable for noise-sensitive scenarios such as residences and offices; at the same time, it reduces the problem of traditional rubber strips directly rubbing against the inner wall of the side rail system, thus reducing the frequency of component replacement; and the continuous and stable tight tension performance further ensures that the curtain is not prone to loosening or shifting during long-term use, maintaining good core functions such as windproofing and sunshade. IV. In this utility model, the cross-section of the T-shaped slider is designed to be a T-shaped structure that matches the cross-section of the T-shaped groove. This design has two technical advantages: First, the geometric adaptability of the T-shaped cross-section provides a stable structural foundation for the sliding insertion assembly of the T-shaped slider and the T-shaped groove. Through the precise matching of the T-shaped protrusion and the corresponding groove in the inner cavity of the T-shaped groove, the two can be smoothly slidably installed along a preset path. Compared with the traditional adhesive fixing method, it completely avoids the risk of delamination caused by the aging and failure of the adhesive. Moreover, the T-shaped sliding insertion structure simplifies the assembly process and does not rely on the curing time of the adhesive, ensuring the long-term reliability of the assembly connection. Second, the elastic deformation capability of the T-shaped slider itself will cause adaptive expansion after it is inserted into the inner cavity of the T-shaped groove, forming a tight interference fit and snap-fit ​​effect. This will then form a lateral constraint on the assembly of the T-shaped slider and the mounting strip in the inner cavity of the T-shaped groove, effectively limiting its displacement in the lateral direction along the side rail and ensuring the lateral positional stability of the overall structure. V. In this utility model, multiple sets of curtain positioning components are respectively arranged in the inner cavities of the two sets of T-shaped sliding grooves symmetrically distributed on the side rail. The positioning components in the inner cavities of the two sets of T-shaped sliding grooves adopt an alternating layout design. This layout makes the side rail form a bidirectional stable internal support positioning structure with balanced side wall force. By applying symmetrical and uniform internal support force from both sides of the side rail through the alternating positioning components, it is ensured that the side rail and the inner wall of the cavity enclosed by the first frame and the second frame are kept in high contact. This ensures the vertical posture accuracy of the curtain positioned in the middle of the side rail relative to the side rail, fundamentally avoiding the problem of side rail force imbalance caused by uneven distribution of curtain positioning components. It effectively prevents the side rail from tilting in the inner cavity of the first frame and the second frame, and further avoids the risk of abnormal friction between the side edge of the curtain and the edge of the first frame and the second frame caused by the side rail in the tilted state. This reduces the curtain wear rate, extends the curtain service life, reduces the operating noise caused by friction, and ensures the smoothness of curtain lifting and sliding, further improving the overall system's user experience and reliability. VI. In this utility model, two sets of elastic components consisting of leaf springs, protrusions, and hemispherical ends are symmetrically configured at the upper and lower ends of each set of T-shaped slide bars and mounting strips. This symmetrical layout ensures that the leaf springs can form a smooth sliding connection with the inner cavity enclosed by the first and second frame sides along the direction from the top to the bottom of the T-shaped slide groove. Its sliding guidance provides convenience for the initial insertion of the T-shaped slide bars and mounting strips into the inner cavity of the T-shaped slide groove and the completion of assembly. Precise docking can be achieved without additional adjustment of the component posture, simplifying the assembly operation process. At the same time, the two sets of hemispherical ends symmetrically distributed at two points can form a stable bidirectional elastic abutment support structure at both ends of each set of T-shaped slide bars and mounting strips. By applying a balanced elastic force at both ends simultaneously, the T-shaped slide bars and mounting strips are prevented from unilaterally shifting or tilting in the inner cavity of the T-shaped slide groove, thereby strengthening the force balance of the side rail and the curtain fabric positioned at the side rail in the inner cavity of the first and second frame sides, and further ensuring the flatness of the curtain fabric. VII. In this utility model, the leaf spring component has a V-shaped structure in its natural state, and its bending deformation range is limited to 60° to 0°. That is, the initial included angle of the leaf spring when it is not under force and the minimum included angle when it reaches the maximum compression state constitute the range of 60° to 0°. This angle range setting enables the leaf spring to provide elastic support force for the component side rail to meet the usage requirements, and also reduces the difficulty of manually pressing the leaf spring, ensuring that the hemispherical end can stably abut against the corresponding positions of the first frame and the second frame. In summary, the windproof curtain side rail system of this utility model has significant benefits in multiple dimensions: First, by constructing a mechanical positioning component through the collaborative efforts of T-shaped sliding strips, mounting strips, hollow cavities, leaf springs, and protrusions, it replaces the traditional sponge strip adhesive method, fundamentally avoiding the risk of adhesive failure and delamination, preventing curtain derailment, improving the curtain's resistance to external deformation and overall service life, and reducing maintenance costs; Second, using the metal elastic leaf spring as the core rebound component, it breaks through the limitation of the single elasticity of traditional adhesive strips. Its elastic decay rate is much lower than that of adhesive strips, and it can uniformly transmit elastic force to achieve full-width flattening of the curtain, reducing dependence on the elasticity of adhesive strips and enhancing the long-term reliability and environmental adaptability of the system; Third, the tight contact achieved by the leaf spring and the low-friction contact of the hemispherical outer wall of the hemispherical end significantly reduces operating friction noise, making it suitable for noise-sensitive scenarios. At the same time, it reduces component wear, ensures long-term tight tension of the curtain, and maintains the core functions of windproof and sunshade; fourth, the T-shaped cross-section design of the T-shaped slider not only achieves smooth sliding and insertion with the T-shaped groove, avoiding delamination problems and simplifying the assembly process, but also ensures the lateral stability of the T-shaped slider and the mounting strip through elastic expansion snap-fit; fifth, the positioning components of the inner cavity of the two sets of T-shaped grooves on the side rail are staggered vertically to form a bidirectional balanced internal support positioning, avoids the side rail tilting, prevents abnormal friction of the curtain side edge, extends the curtain life and ensures smooth sliding; sixth, each set of T-shaped sliders and mounting strips is symmetrically equipped with leaf springs, protrusions and hemispherical end elastic components at both ends, which not only simplifies assembly and docking, but also avoids component displacement through bidirectional elastic support, strengthens the force balance and flatness of the curtain, and comprehensively improves the system's performance and reliability.

[0015] The following are specific implementation cases and appendices. Figures 1 to 12 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0016] Example 1 See Figures 1 to 10As shown, a high-resilience noise-reducing windproof curtain side rail system includes a first frame 1 and a second frame 2. The semi-enclosed structure cavity formed by the first frame 1 and the second frame 2 also includes a side rail assembly. The side rail assembly is slidably embedded in the semi-enclosed structure cavity. Multiple sets of curtain positioning assemblies are arranged between the side rail assembly and the semi-enclosed structure cavity. Each set of curtain positioning assemblies includes: a T-shaped slider 6, a mounting strip 7, a hollow cavity 8, a leaf spring 9, a protrusion 10, and a hemispherical end 11. The T-shaped slider 6 is arranged vertically in the side rail assembly cavity; the mounting strip 7 is arranged on the side wall of the T-shaped slider 6 and is connected to the T-shaped slider. 6. Forming an integrated structure; T-shaped slider 6 and mounting strip 7 are both made of rubber or other materials with elastic deformation capability, and their elastic deformation capability is sufficient to achieve the stability of T-shaped slider 6 and mounting strip 7 after installation in the inner cavity of T-shaped groove 5. The material is not limited or described in detail here; Hollow cavity 8 is opened vertically through the mounting strip 7; Two sets of leaf springs 9 are symmetrically inserted into the upper and lower ends of the inner cavity of hollow cavity 8; Protrusion 10 is set on the outer wall of leaf spring 9; Hemispherical end 11 is set on the outer wall of the side of protrusion 10 away from leaf spring 9, and the outer wall of hemispherical end 11 is hemispherical.

[0017] Specifically, the leaf spring 9 is made of a metallic elastic material. In this application, it uses 65Mn spring steel, whose elastic properties meet the requirements for elastic limit and fatigue life in the standard "Spring Steel" [GB / T 1222-2016]. The elastic decay rate affected by environmental factors is only 1 / 5 of that of traditional rubber strips. Firstly, it can maintain a stable elastic output for a long time, avoiding a decrease in the curtain's rebound ability due to elastic failure. Secondly, the mechanical cooperation structure of the leaf spring 9 with the T-shaped slide bar 6, mounting bar 7, hollow cavity 8, and protrusion 10 allows the elastic force to be evenly transmitted to the side edge of the curtain, achieving uniform stretching of the entire curtain surface. Compared with the curtain wrinkling problem caused by uneven elasticity of the rubber strip, this further improves the flatness of the curtain. Thirdly, by replacing the rubber strip with the leaf spring 9 as the core rebound component, the dependence on the elastic performance of the rubber strip is greatly reduced. Even if the rubber strip deteriorates to a certain extent due to long-term use, it will not directly affect the rebound and stretching effect of the curtain, significantly improving the long-term reliability and environmental adaptability of the side rail system, and extending the maintenance cycle and service life of the overall device.

[0018] This invention utilizes the coordinated operation of a T-shaped slider 6, mounting strip 7, hollow cavity 8, leaf spring 9, and protrusion 10 to construct a stable curtain positioning component within the side rail system, ensuring it remains permanently within the cavity. This component replaces traditional adhesive bonding with precise mechanical fitting and positioning, fundamentally avoiding the risk of delamination caused by adhesive failure and completely eliminating the problem of the curtain detaching from the side rail along with the sponge strip. Compared to adhesive methods, the mechanical positioning structure offers superior stability, reliably constraining the curtain's side edges for extended periods, ensuring the curtain remains within the preset positioning range and preventing shifting and wrinkling. It also enhances the curtain's resistance to external deformation—resisting greater wind force and human impact, and quickly resetting after external force, reducing the impact on the curtain's structure and performance, thereby extending the overall lifespan of the windproof curtain and reducing the frequency and cost of maintenance related to positioning failures.

[0019] This invention uses a leaf spring 9 as the core elastic output component, which, together with a T-shaped slider 6, mounting strip 7, hollow cavity 8, and protrusion 10, forms a curtain positioning assembly, breaking the limitation of the single elastic source of traditional rubber strips. Its elasticity coverage far exceeds the elastic deformation range of the rubber strip, and through continuous and tight contact with the inner cavity of the side rail system, it can provide stable and durable elastic constraint for the curtain. On the one hand, the leaf spring 9 uses a metallic elastic material, and its elasticity decay rate due to environmental influences is less than 1 / 5 of that of traditional rubber strips, enabling it to output elasticity stably for a long time and preventing a decrease in the curtain's rebound ability. On the other hand, the mechanical cooperation between the leaf spring 9 and other components can evenly transmit the elasticity to the side edges of the curtain, achieving uniform stretching across the entire width and solving the problem of curtain wrinkles caused by uneven local elasticity of the rubber strip. Meanwhile, by replacing the rubber strip with a leaf spring 9 as the core rebound component, the reliance on the elastic performance of the rubber strip is greatly reduced. Even if the rubber strip deteriorates due to aging after long-term use, it will not directly affect the rebound and stretching effect of the curtain, effectively improving the long-term reliability and environmental adaptability of the side rail system, and extending the maintenance cycle and service life of the overall device.

[0020] This solution utilizes the continuous and tight contact between the leaf spring 9 and the inner cavity of the side rail system, combined with the adaptive contact between the hemispherical outer wall of the hemispherical end 11 and the inner walls of the first frame 1 and the second frame 2 of the side rail body, to construct a dual-optimized structure. In terms of noise reduction, compared to the noise generated by the rigid friction between the traditional elastic element and the rail wall during repeated deformation and rebound, the tight contact of the leaf spring 9 reduces unnecessary swaying of the elastic element. Furthermore, the hemispherical outer wall of the hemispherical end 11 transforms sliding contact into low-friction point contact, significantly reducing friction noise and improving the quietness of the equipment, making it particularly suitable for noise-sensitive environments such as residences and offices. In terms of structural constraint and functional assurance, this structure can continuously and stably constrain the entire curtain and side rail assembly, ensuring that it remains tightly stretched within the inner cavity enclosed by the first frame 1 and the second frame 2. This avoids the shortened lifespan caused by direct friction between the traditional rubber strip and the rail wall, reducing the frequency of component replacement, and also prevents the curtain from loosening or shifting during long-term use, ensuring the stable performance of core functions such as windproofing and sunshade.

[0021] For specific main references Figures 2 to 9 As shown, the side rail assembly includes: a side rail 3, a curtain positioning strip 4, and a T-shaped groove 5. The side rail 3 is embedded vertically into the cavity of the semi-enclosed structure. The curtain positioning strip 4 is opened vertically in the middle of the side rail 3, and the curtain positioning strip 4 is located on the side of the side rail 3 away from the cavity of the semi-enclosed structure. There are two sets of T-shaped grooves 5, which are symmetrically opened vertically on both sides of the side rail 3, and the T-shaped grooves 5 are located on the side of the side rail 3 away from the cavity of the semi-enclosed structure.

[0022] In this invention, two sets of elastic components, consisting of leaf springs 9, protrusions 10, and hemispherical ends 11, are symmetrically arranged at the upper and lower ends of each set of T-shaped slide bars 6 and mounting strips 7. From the perspective of structural adaptability, this symmetrical layout ensures that the leaf springs 9 can form a smooth sliding connection with the inner cavity enclosed by the first frame 1 and the second frame 2 along the direction from the top to the bottom of the T-shaped slide groove 5. Its built-in sliding guide function facilitates the initial insertion of the T-shaped slide bars 6 and mounting strips 7 into the inner cavity of the T-shaped slide groove 5 and completes the assembly. Precise docking can be achieved without additional adjustment of the component posture, greatly simplifying the assembly operation process. From the perspective of stress stability, the two sets of hemispherical ends 11, symmetrically distributed at two points, can construct a stable bidirectional elastic abutment support structure at both ends of each set of T-shaped sliders 6 and mounting strips 7: by applying balanced elastic force at both ends simultaneously, it can effectively avoid the problem of unilateral displacement or tilting of T-shaped sliders 6 and mounting strips 7 in the inner cavity of T-shaped grooves 5; and this stable support relationship will be further transmitted to the side rail 3 and the curtain fabric positioned at the side rail 3, strengthening the stress balance of the two in the inner cavities of the first frame 1 and the second frame 2, and ultimately ensuring that the curtain fabric is always in a flat state.

[0023] Main references Figure 6As shown, the curtain positioning components located within the inner cavities of the two sets of T-shaped grooves 5 are arranged in a staggered manner. This invention configures multiple sets of curtain positioning components within the inner cavities of the two sets of T-shaped grooves 5 symmetrically distributed on the side rail 3, employing a staggered layout design. This layout enables the side rail 3 to form a bidirectional stable internal support positioning structure with balanced sidewall force. The staggered positioning components apply symmetrical and uniform internal support force from both sides of the side rail 3, ensuring that the side rail 3 is highly fitted to the inner wall of the cavity enclosed by the first frame 1 and the second frame 2, thereby ensuring the vertical orientation accuracy of the curtain in the middle of the side rail 3 relative to the side rail 3. This design fundamentally solves the problem of uneven force imbalance on the side rail 3 caused by uneven distribution of the curtain positioning components, effectively preventing the side rail 3 from tilting within the inner cavities of the first frame 1 and the second frame 2. It avoids abnormal friction between the side edge of the curtain and the edges of the first frame 1 and the second frame 2 when tilted, thus reducing curtain wear, extending its service life, reducing operating noise generated by friction, and ensuring smooth curtain lifting and sliding, comprehensively improving the overall user experience and reliability of the system.

[0024] Main references Figure 2 , Figure 4 and Figure 7 As shown, the T-shaped slider 6 is slidably embedded in the inner cavity of the T-shaped groove 5, and the T-shaped cross-section of the T-shaped slider 6 is adapted to the inner cavity of the T-shaped groove 5. This invention designs the cross-section of the T-shaped slider 6 as a T-shaped structure adapted to the cross-section of the T-shaped groove 5. On the one hand, the geometric matching characteristics of the T-shaped cross-section provide stable structural support for the sliding insertion assembly of the T-shaped slider 6 and the T-shaped groove 5. The precise fit between the protrusion and the corresponding groove in the inner cavity of the T-shaped slide 5 allows for smooth sliding installation along a preset path. This not only completely avoids the risk of adhesive failure due to aging in traditional adhesive methods, but also simplifies the assembly process by eliminating the need to wait for the adhesive to cure, ensuring the long-term reliability of the assembly connection. On the other hand, relying on the elastic deformation capability of the T-shaped slide 6 itself, it will expand adaptively after being inserted into the inner cavity of the T-shaped slide 5, forming a tight interference fit and snap-fit ​​effect. This creates a lateral constraint on the assembly of the T-shaped slide 6 and the mounting strip 7 in the inner cavity of the T-shaped slide 5, effectively limiting the displacement of the assembly along the lateral direction of the side rail 3, and ensuring the lateral stability of the overall structure.

[0025] Main references Figure 10 As shown, the leaf spring 9 is V-shaped in its natural state, and the range between the initial included angle of the leaf spring 9 and the minimum included angle under the maximum compression state is 60° to 0°. This angle range setting is both practical and operable: on the one hand, it can ensure that the leaf spring 9 provides elastic support force to the component side rail 3 in accordance with the usage requirements and meets the structural support requirements; on the other hand, it can reduce the difficulty of manually pressing the leaf spring 9 and ensure that the hemispherical end 11 can stably abut against the corresponding positions of the first frame 1 and the second frame 2, taking into account both functional performance and assembly convenience.

[0026] Main references Figure 2 As shown, the hemispherical end 11 fits against the inner sidewalls of the first frame 1 and the second frame 2, thereby providing elastic support for the edge rail 3 to elastically abut against the first frame 1 and the second frame 2. (See main references) Figures 4 to 6 As shown, a plug 12 is inserted into the top of the side rail 3 to provide connection and protection for the windproof curtain top beam, as well as to provide guidance for the installation of the curtain fabric.

[0027] Main references Figure 7 , Figure 8 , Figure 10 As shown, the protrusion 10 is set as a solid cylindrical structure. This structure of the protrusion 10 can ensure that the protrusion 10 and the hemispherical end 11 have sufficient elastic support strength and are not easily deformed during the support process.

[0028] It is also worth noting that the application scope of this application is not limited to the field of windproof curtains. Its core function is adaptable to all application scenarios within this technical field that require the curtain fabric to be spring-loaded and stretched flat. Taking existing sunshade products with curtain structures, such as sunshades, as an example, in actual use, the curtain fabric is easily wrinkled or shifted by external forces such as wind and human touch. By applying this side rail system to these products, through precise positioning and constraint of the side edges of the sunshade curtain fabric, and relying on the high resilience of the system itself, the curtain fabric can be quickly driven to return to a flat state after the external force disappears. This ensures both the appearance regularity of the sunshade product and maintains its effective shading area and performance. In addition, for other products that require maintaining the flatness and stability of the curtain fabric, such as some industrial dustproof curtains and indoor partition curtains, this system can also meet their core usage requirements by positioning and controlling the spring-loaded flatness of the curtain fabric's side edges, demonstrating broad scenario adaptability and technical versatility.

[0029] The assembly process of the high-resilience noise-reducing windproof curtain side rail system in this embodiment is as follows: Insert the end of the leaf spring 9 without the protrusion 10 into the inner cavity of the corresponding hollow cavity 8, so that the inner corner of the leaf spring 9 fits with the end edge of the mounting strip 7, and complete the insertion connection between the leaf spring 9 and the end of the mounting strip 7; slide the T-shaped slide bar 6 and the mounting strip 7 assembly, which have leaf springs 9 assembled at both ends, into the inner cavity of the corresponding T-shaped slide groove 5; by pulling and adjusting the leaf spring 9, the installation position of the T-shaped slide bar 6 in the inner cavity of the T-shaped slide groove 5 can be adjusted to ensure that the T-shaped slide bars 6 in the two sets of T-shaped slide grooves 5 are alternately staggered in position. The side rail 3, equipped with multiple sets of T-shaped sliders 6 and leaf springs 9, is inserted vertically into the semi-enclosed cavity formed by the first frame 1 and the second frame 2. During the process, the leaf springs 9 are manually driven to compress and deform, so that the hemispherical end 11 of the leaf springs 9 fits against the inner wall of the first frame 1 and the second frame 2 at the corresponding position. The elasticity of the multiple sets of leaf springs 9 is used to tightly press the side rail 3 against the inner wall of the semi-enclosed cavity of the first frame 1 and the second frame 2. After the assembly is completed, the plug 12 is inserted and sealed at the top end of the side rail 3. Then, the curtain is positioned on the existing curtain positioning strip, and the positioning strip is slidably inserted vertically into the inner cavity of the plug 12 and the curtain positioning strip 4 to realize the connection and fixation of the side edge of the curtain in the inner cavity of the curtain positioning strip 4. When the curtain fabric wrinkles or deforms due to wind or other external forces, it will cause the side rail 3 to move away from the first frame 1 and the second frame 2 to partially enclose the inner cavity of the structure, causing the leaf spring 9 to be forced to compress and deform. The elastic force of the leaf spring 9 will push the side rail 3 back to the direction closer to the first frame 1 and the second frame 2 to partially enclose the inner cavity of the structure. The movement of the side rail 3 will drive the curtain fabric to automatically straighten, ensuring that the curtain fabric can automatically return to a flat state after being subjected to external forces. This utility model's windproof curtain side rail system has several significant advantages: First, by using a mechanical positioning assembly constructed collaboratively by a T-shaped slide bar 6, mounting bar 7, hollow cavity 8, leaf spring 9, and protrusion 10, it replaces the traditional sponge strip adhesive method, fundamentally avoiding the risk of adhesive failure and delamination, preventing curtain derailment, improving the curtain's resistance to external deformation and overall service life, and reducing maintenance costs; Second, using the metal elastic leaf spring 9 as the core rebound component, it breaks through the limitation of the single elasticity of traditional adhesive strips. Its elastic decay rate is much lower than that of adhesive strips, and it can evenly transmit elastic force to achieve full-width flattening of the curtain, reducing dependence on the elasticity of adhesive strips and enhancing the system's long-term reliability and environmental adaptability; Third, the tight contact achieved by the leaf spring 9 and the low-friction contact of the hemispherical outer wall of the hemispherical end 11 significantly reduces operating friction noise, making it suitable for noise-sensitive scenarios, while also reducing... The design minimizes wear on components, ensuring long-term tight tension of the curtain fabric and maintaining its core functions of windproofing and sunshade. Fourthly, the T-shaped cross-section design of the T-shaped slider 6 allows for smooth sliding and insertion with the T-shaped groove 5, avoiding delamination and simplifying the assembly process. It also ensures the lateral stability of the T-shaped slider 6 and mounting strip 7 through elastic expansion and locking. Fifthly, the positioning components within the inner cavities of the two sets of T-shaped grooves 5 on the side rail 3 are staggered vertically, forming a bidirectional balanced internal support positioning, preventing the side rail 3 from tilting, preventing abnormal friction on the side edges of the curtain fabric, extending the curtain fabric's lifespan, and ensuring smooth sliding. Sixthly, each set of T-shaped sliders 6 and mounting strip 7 is symmetrically equipped with leaf springs 9, protrusions 10, and hemispherical end caps 11 at both ends, simplifying assembly and preventing component misalignment through bidirectional elastic support. This enhances the balance of force on the curtain fabric and its flatness, comprehensively improving the system's performance and reliability.

[0030] Example 2 like Figure 11 and Figure 12 As shown, the difference between this embodiment and embodiment 1 is that the protrusion 10 is set as a hollow columnar structure with openings on both sides. This structure is easier to process and form in one piece, saves materials, and can also meet the abutment connection requirements at the inner walls of the first frame 1 and the second frame 2.
