Description

Technical Field

[0001] This utility model relates to the field of screen technology, specifically providing a protective screen steel strip handle plug structure. Background Technology

[0002] In existing screen window structures, the connection and fixation of the handle to the screen mesh is a crucial step in ensuring the normal use of the screen window. Traditional screen window handles are mostly installed and fixed using adhesive bonding, that is, the handle is directly glued to the screen mesh or screen window profile to achieve the connection between the handle and the screen window.

[0003] However, this adhesive fixing method has obvious drawbacks. Over long-term use, the adhesive is susceptible to aging due to environmental factors, leading to a gradual decrease in bonding strength and even adhesive failure. Once the adhesive fails, the connection between the handle and the screen will loosen, not only affecting the normal sliding operation of the screen and reducing its ease of use, but also potentially causing the screen to sway, shift, or even pose a safety hazard due to unstable connection.

[0004] Accordingly, there is a need in the field for a new protective screen window steel strip handle plug structure to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that existing screen window handle plugs are prone to loosening after long-term use.

[0006] This utility model provides a protective screen window steel strip handle plug structure, including:

[0007] A steel strip is fixedly installed along the length of the side of the screen window;

[0008] A clamping block assembly is installed at the bottom of both sides of the screen window; the clamping block assembly includes an upper clamping block and a lower clamping block, the upper clamping block is disposed on a first surface of the screen window, the lower clamping block is disposed on a second surface of the screen window, and the upper clamping block and the lower clamping block form a clamping structure for the screen window;

[0009] A handle is provided at the bottom of the screen window, and both ends of the handle are inserted into the upper clamping block;

[0010] A connecting block is disposed at one end of the lower clamping block near the side of the screen window;

[0011] A retaining buckle, the first end of which is detachably mounted on the steel strip, and the second end of which is fixedly mounted on the connecting block.

[0012] Based on the above configuration, a steel strip is used to fix the screen window along its side to provide an overall support foundation. The upper and lower clamping blocks of the clamping block assembly form a clamping structure for the screen window, achieving a stable connection between the handle and the screen window and avoiding the loosening problem of traditional connection methods. The plug-in design of the handle and the upper clamping block simplifies the installation process and facilitates later disassembly and maintenance. The detachable fastener eliminates the need to use glue to fix the screen window, solving the problem of easy aging and failure of adhesive fixation in existing technologies, and improving structural stability and service life.

[0013] In the preferred technical solution of the above-mentioned protective screen window steel strip handle plug structure, the fixing buckle includes a pad, a protrusion and a fixing ring. The side of the steel strip has a notch and groove. The protrusion is disposed in the notch and groove. The first end of the protrusion is configured as a hook. The second end of the protrusion is fixedly connected to the lower clamping block through the pad. The fixing ring is installed on the steel strip and is engaged with the hook.

[0014] Based on the above design, the pad of the fixing buckle increases the contact area with the lower clamping block, improving the connection firmness; the protrusion embeds into the notch groove of the steel strip to achieve lateral positioning, preventing the fixing buckle from sliding along the steel strip; the protrusion hook engages with the fixing ring on the steel strip to form longitudinal fixation. This double-limiting design ensures a tight connection between the fixing buckle and the steel strip, effectively preventing loosening and detachment due to vibration during use. The detachable structure retains ease of installation, facilitating later adjustments or replacement of components, further optimizing the reliability of the nail-free fixing.

[0015] In the preferred technical solution of the above-mentioned protective screen window steel strip handle plug structure, the hook structure is set as a T-shaped structure, and a central groove is formed on the fixing ring. The T-shaped structure abuts against the central groove for limiting.

[0016] Based on the above design, the T-shaped hook abuts against the central groove of the fixing ring for limiting the connection. The transverse portion of the T-shaped structure effectively contacts both sides of the central groove, significantly increasing the locking strength and allowing it to withstand greater tensile and shear forces, preventing accidental disengagement. Precise limiting reduces connection gaps, minimizes shaking and noise during use, enhances the overall structural stability, extends product lifespan, and ensures reliable connection over long-term use.

[0017] In the preferred technical solution of the above-mentioned protective screen window steel strip handle plug structure, the steel strip is set as a flexible steel strip.

[0018] Based on the above design, the steel strip is made of a flexible material with good plasticity, allowing it to closely conform to the contours of the screen window's side, thus improving its adaptability to different types of screen windows. Its flexibility allows for buffering deformation under stress, reducing direct impact on the screen window and protecting its structure. Simultaneously, it facilitates flexible adjustment of the fixing position during installation based on the side length, enhancing ease of use.

[0019] In the preferred technical solution of the above-mentioned protective screen window steel strip handle plug structure, the connecting block is provided with a U-shaped mounting buckle, and the U-shaped mounting buckle is set in the slot of the screen window profile.

[0020] Based on the above configuration, the U-shaped mounting buckle on the connecting block embeds into the slot of the screen window profile, forming an additional positioning and fixing point. This, together with the clamping structure of the clamping block assembly, creates a double fixation, distributing the force and preventing excessive local stress that could cause the screen window to deform. The tight fit between the U-shaped structure and the slot further restricts the lateral and longitudinal displacement of the connecting block, improving the overall structure's anti-shaking performance, ensuring stable connection during screen window sliding, and enhancing safety in use.

[0021] In the preferred technical solution of the above-mentioned protective screen window steel strip handle plug structure, an upper limit plate is provided between the upper clamping block and the screen window profile; a lower limit plate is provided between the lower clamping block and the screen window profile.

[0022] Based on the above configuration, upper and lower limiting plates are respectively positioned between the upper clamping block, lower clamping block, and screen window profile. Through the precise positioning function of the limiting plates, the clamping block assembly quickly finds its installation position, improving assembly efficiency and consistency. The limiting plates increase the contact friction between the clamping block and the profile, preventing the clamping block from sliding or rotating along the screen window surface during use, ensuring a stable clamping structure. Simultaneously, the limiting plates reduce direct hard contact between the clamping block and the profile, preventing surface wear and protecting the integrity of the screen window's appearance.

[0023] In the preferred technical solution of the above-mentioned protective screen window steel strip handle plug structure, the handle is set as an aluminum alloy structure.

[0024] Based on the above design, the handle adopts an aluminum alloy structure. Utilizing the high strength and lightweight properties of aluminum alloy, the load on the clamping components and screen is reduced while ensuring the handle's load-bearing capacity, thus lowering the risk of screen sagging due to long-term use. Aluminum alloy possesses excellent corrosion resistance and oxidation resistance, resisting moisture and dust erosion, and is not prone to rusting or aging, extending the handle's lifespan. Furthermore, aluminum alloy is aesthetically pleasing and easy to clean, enhancing the overall quality and durability of the product.

[0025] In the preferred technical solution of the above-mentioned protective screen window steel strip handle plug structure, the handle is set as a hollow structure, and the handle is inserted into the upper clamping block through the hollow structure.

[0026] Based on the above design, the handle adopts a hollow structure, which further reduces weight while ensuring structural strength, lowers resistance during screen sliding, and makes operation more effortless and smooth. The interlocking fit between the hollow structure and the upper clamping block simplifies the connection between the handle and the clamping block assembly, allowing for assembly without complex tools and facilitating future maintenance and replacement. At the same time, the hollow design saves material costs, and the internal space can accommodate different sizes of interlocking structures, enhancing the product design flexibility and adaptability.

[0037] First refer to Figures 1 to 4 ,like Figures 1 to 4 As shown, this utility model provides a protective screen window steel strip handle plug structure, including:

[0038] Steel strip 8 is fixedly installed along the length of the side of the screen window;

[0039] The clamping block assembly is installed at the bottom of both sides of the screen window; the clamping block assembly includes an upper clamping block 1 and a lower clamping block 2, the upper clamping block 1 is set on the first surface of the screen window, and the lower clamping block 2 is set on the second surface of the screen window, the upper clamping block 1 and the lower clamping block 2 form a clamping structure for the screen window.

[0040] Handle 11 is located at the bottom of the screen window, and both ends of the handle 11 are inserted into the upper clamping block 1;

[0041] Connecting block 3 is located at one end of the lower clamping block 2 near the side of the screen window;

[0042] The fixing buckle has its first end detachably mounted on the steel strip 8, and its second end fixedly mounted on the connecting block 3. It should be noted that this invention does not impose any limitations on the specific structure of the fixing buckle; those skilled in the art can design it according to their needs. For example, the fixing buckle can be an elastic pin, or it can be a rotary lock, as long as it can be stably fixed for a long time. In this preferred embodiment, the fixing buckle includes a pad 12, a protrusion 7, and a fixing ring 6. A notch / groove is formed on the side of the steel strip 8, and the protrusion 7 is disposed within the notch / groove. The first end of the protrusion 7 is configured as a hook, and the second end of the protrusion 7 is fixedly connected to the lower clamping block 2 via the pad 12. The fixing ring 6 is mounted on the steel strip 8 and engages with the hook. The pad 12 of the fixing buckle increases the contact area with the lower clamping block 2, improving the connection firmness; the protrusion 7 is embedded in the notch groove of the steel strip 8 to achieve lateral positioning and prevent the fixing buckle from sliding along the steel strip 8; the hook of the protrusion 7 engages with the fixing ring 6 on the steel strip 8 to form a longitudinal fixation, and the double limit ensures that the fixing buckle and the steel strip 8 are tightly connected, effectively avoiding loosening and falling off due to vibration during use. The detachable structure retains the convenience of installation, making it easy to adjust or replace parts later, and further optimizing the reliability of nail-free fixing. The hook structure is set as a T-shaped structure, and a central groove is formed on the fixing ring 6. The T-shaped structure abuts against the central groove for limit. The T-shaped hook abuts against the central groove of the fixing ring 6, and the lateral part of the T-shaped structure forms an effective abutment with the two sides of the central groove, which greatly improves the clamping strength, can withstand greater tensile and shear forces, and prevents the hook from accidentally falling off. The precise limit fit reduces the connection gap, reduces shaking and noise during use, enhances the stability of the overall structure, extends the product's service life, and ensures the connection reliability during long-term use.

[0043] The steel strip 8 provides an overall support base by fixing it along the side of the screen window. The upper and lower clamping blocks 2 of the clamping block assembly form a clamping structure for the screen window, realizing a stable connection between the handle 11 and the screen window, avoiding the loosening problem of traditional connection methods. The plug-in design of the handle 11 and the upper clamping block 1 simplifies the installation process and facilitates later disassembly and maintenance. The detachable fastener eliminates the need to use glue to fix the screen window, solving the problem of easy aging and failure of adhesive fixation in the existing technology, and improving structural stability and service life.

[0044] In a preferred embodiment, the steel strip 8 is configured as a flexible steel strip 8. The steel strip 8 is made of a flexible material, possessing good plasticity, and can closely conform to the contours of the screen window's side, improving its adaptability to different types of screen windows. Its flexibility allows for buffering deformation under stress, reducing direct impact on the screen window and protecting its structure. Simultaneously, it facilitates flexible adjustment of the fixing position according to the side length during installation, enhancing ease of use. It should be noted that this utility model does not impose any limitations on the specific structure of the steel strip 8; those skilled in the art can design it according to their needs, as long as the steel strip 8 can fit well with the screen mesh.

[0045] Furthermore, a U-shaped mounting buckle 4 is provided on the connecting block 3, and the U-shaped mounting buckle 4 is set in the slot of the screen window profile 5. The U-shaped mounting buckle on the connecting block 3 is embedded in the slot of the screen window profile 5, forming an additional positioning and fixing point, which forms a double fixation with the clamping structure of the clamping block assembly, distributing the force and avoiding excessive local stress that could cause the screen window to deform. The tight fit between the U-shaped structure and the slot further restricts the lateral and longitudinal displacement of the connecting block 3, improves the overall structure's anti-shaking performance, ensures stable connection during screen window sliding, and enhances safety. It should be noted that this utility model does not impose any restrictions on the specific structure of the U-shaped mounting buckle 4. Those skilled in the art can set it according to their needs. For example, the U-shaped mounting buckle 4 can be set as an elastic structure, or it can be set as a non-elastic structure, as long as the U-shaped mounting buckle 4 and the profile 5 are stably fitted together.

[0046] Furthermore, an upper limit plate 9 is provided between the upper clamping block 1 and the screen profile 5; a lower limit plate 10 is provided between the lower clamping block 2 and the screen profile 5. The upper and lower limit plates 10 are respectively located between the upper clamping block 1, the lower clamping block 2, and the screen profile 5. Through the precise positioning function of the limit plates, the clamping block assembly can quickly find the installation position, improving assembly efficiency and consistency. The limit plates increase the contact friction between the clamping block and the profile 5, preventing the clamping block from sliding or rotating along the screen surface during use, ensuring the stability of the clamping structure. At the same time, the limit plates can reduce the direct hard contact between the clamping block and the profile 5, avoiding wear on the profile surface and protecting the appearance integrity of the screen.

[0047] As a preferred embodiment, the handle 11 is made of aluminum alloy. Utilizing the high strength and lightweight properties of aluminum alloy, the handle 11 maintains its load-bearing capacity while reducing the load on the clamping assembly and the screen, thus mitigating the risk of screen sagging over long-term use. Aluminum alloy possesses excellent corrosion resistance and oxidation resistance, resisting moisture and dust erosion, and is not prone to rusting or aging, extending the service life of the handle 11. Furthermore, the aluminum alloy material is aesthetically pleasing and easy to clean, enhancing the overall texture and durability of the product. The handle 11 has a hollow structure, which connects to the upper clamping block 1. This hollow structure further reduces weight while maintaining structural strength, lowering resistance during screen sliding and making operation smoother and easier. The plug-in connection between the hollow structure and the upper clamping block 1 simplifies the connection between the handle 11 and the clamping assembly, allowing assembly without complex tools and facilitating future maintenance and replacement. Meanwhile, the hollow design saves material costs, and the internal space can accommodate different specifications of plug-in structures, enhancing the flexibility and adaptability of product design.

[0048] By pulling the aluminum alloy handle 11, the mesh can slide up and down along the side profile 5. During the sliding process, the steel strip 8 provides support for the mesh through the fixed cooperation with the handle plug, and the protrusion 7 ensures that the steel strip 8 and the handle plug will not loosen or detach due to sliding force.
