[0002] As an important component of building doors and windows, window screens primarily function to provide ventilation and insect control, while also addressing additional needs such as dust prevention and protection. They are widely used in various settings including residential, commercial, and office buildings. However, with increasing demands for living comfort, architectural aesthetics, and ease of use, traditional window screens are no longer sufficient to meet modern consumer needs.

[0003] While existing high-strength laser-welded narrow-frame detachable screens achieve structural connections for narrow-frame designs using laser welding, they still have several technical shortcomings in practical applications: the overall frame has weak resistance to deformation, and due to the limitations of the narrow-frame structure, it lacks an effective rigid reinforcement structure. Under long-term use or external force, it is prone to bending, warping, and other deformations, affecting the screen's sealing performance and service life; the disassembly and assembly operations are cumbersome and inconvenient, the existing snap-fit ​​or fixing structure design is unreasonable, the disassembly and assembly process requires additional tools, and the alignment accuracy is insufficient, which is time-consuming and labor-intensive.

[0004] Therefore, in view of the existing high-strength laser-welded narrow-frame detachable screen windows, which have problems such as weak resistance to deformation, inconvenient disassembly and assembly, easy jamming when opening and closing, and insufficient versatility and durability, a solution is needed to address the problems of inconvenient disassembly and weak resistance to deformation.

[0009] As a further improvement of this utility model, the rear outer wall of the snap-fit ​​block is fixedly connected with a connecting plate, and the opposite side of the rear end of the connecting plate is set as an inclined surface.

[0010] As a further improvement of this utility model, the inner wall of the connecting plate is provided with a locking hole, the size of which is adapted to the insertion rod.

[0011] As a further improvement of this utility model, a sleeve is fitted on the outer wall of the reinforcing rod, and bolts are provided on the inner walls of the left and right sides of the top end of the sleeve.

[0012] As a further improvement of this utility model, the outer wall of the bolt penetrates the inner walls of the left and right sides of the top end of the reinforcing rod and is threadedly connected to the threaded hole.

[0030] Example 1: Refer to Figures 1-3 A high-strength laser-welded narrow-frame, deformation-resistant, detachable screen window includes a slide rail 1, a slider 3 slidably connected to the top of the slide rail 1, a frame 2 fixedly connected to the top of the slider 3, a main screen window 4 installed on the inner wall of the frame 2, reinforcing ribs 5 fixedly connected to the inner wall of the frame 2, fixing blocks 6 fixedly connected to both sides of the front outer wall of the frame 2, insert rods 7 slidably connected to the inner walls of the upper and lower ends of the fixing blocks 6, and limit plates 8 fixedly connected to the outer walls of the insert rods 7. Each block is equipped with a spring 9, and each of the front outer walls of the fixing block 6 is equipped with a snap-fit ​​block 10. The opposite end of each spring 9 is connected to the opposite side of the limiting plate 8, and the opposite end of each spring 9 is connected to the inner wall of the fixing block 6. The outer wall of the limiting plate 8 is slidably connected to the inner wall of the fixing block 6. Each of the rear outer walls of the snap-fit ​​block 10 is fixedly connected with a connecting plate 11. The opposite side of the rear end of the connecting plate 11 is set as an inclined surface. Each of the inner walls of the connecting plate 11 is provided with a snap-fit ​​hole, the size of which is adapted to the insertion rod 7.

[0031] Specifically, slider 3 drives frame 2 to slide smoothly along slide rail 1, realizing the opening and closing operation of the screen window and ensuring smooth movement without jamming. The main screen window 4 is fixed by high-strength laser welding process, realizing the core functions of insect prevention and ventilation. While adapting to the narrow frame design, it also improves the connection strength. The reinforcing rib 5 is made of Q235 cold-rolled steel, which enhances the structural rigidity and deformation resistance of frame 2, preventing the narrow frame from deforming due to stress or use, and ensuring the overall stability of the screen window. The fixing block 6 provides installation support for components such as the insertion rod 7 and spring 9, and builds a stable foundation for the detachable snap-fit ​​structure. The insertion rod 7 moves along the fixed rail 1. The inner wall of the fixed block 6 slides flexibly, facilitating insertion into the locking hole for a secure engagement. The insertion rod 7 drives the limiting plate 8 to slide synchronously, transmitting the elastic force of the spring 9 while limiting the sliding stroke of the insertion rod 7 to prevent it from falling out of the fixed block 6. The parameters of the fixed block 6 and the fixed spring 9 are: elastic coefficient 1.5~2.5N / mm, working stroke 5~8mm, and elastic force greater than the frictional force of the insertion rod 7, providing a stable and sufficient elastic restoring force for the insertion rod 7. Through the elastic extension and contraction of the spring 9, the limiting plate 8 is pushed, causing the insertion rod 7 to automatically engage in the locking hole, ensuring a secure connection between the fixed block 6 and the locking block 10. The elastic force of the first spring 13 is greater than the frictional force of the insertion rod 7, ensuring that the spring can smoothly push the insertion rod 7 to overcome friction and engage in the locking hole. This ensures that the fixing block 6 and the locking block 10 are firmly connected and smoothly engaged. The limiting plate 8 restricts the movement trajectory of the limiting plate 8, ensuring that the insertion rod 7 slides smoothly along a straight line, improving the locking accuracy of the insertion rod 7 and the locking hole. The engagement of the insertion rod 7 and the locking hole is achieved through cooperation, and they also jointly fix the reinforcing rod 13, strengthening the overall structural stability. The connecting plate 11 provides the mounting carrier for the locking hole, and the inclined surface at the rear end of the connecting plate 11 provides a guide for the insertion rod 7, facilitating the quick engagement of the insertion rod 7 into the locking hole. To improve installation efficiency, the locking holes are adapted to the size of the insertion rod 7, providing a precise locking point for the insertion rod 7. This ensures a reliable connection between the locking block 10 and the fixing block 6. The locking block 10, together with the reinforcing rod 13 and the fixing block 6, fixes the reinforcing rod 13, further enhancing the overall rigidity and deformation resistance of the frame 2 and improving the structural stability of the screen window. The opposite side of the rear end of the connecting plate 11 is set as an inclined surface to guide the insertion rod 7 into the locking hole, helping the insertion rod 7 to quickly and accurately align and lock, strengthening the structural rigidity and deformation resistance, ensuring a stable connection, and at the same time facilitating the installation and removal of the reinforcing rod 13 and improving overall operation efficiency.

[0032] Example 2: Refer to Figure 1 , Figure 4 and Figure 5A reinforcing rod 13 is installed on the inner wall of the opposite side of the snap-fit ​​block 10 and the fixing block 6. The inner wall of the top end of the reinforcing rod 13 has multiple threaded holes 14. A sleeve 12 is fitted on the outer wall of the reinforcing rod 13. Bolts 15 are provided on the inner walls of the top left and right sides of the sleeve 12. The outer wall of the bolts 15 passes through the inner walls of the top left and right sides of the reinforcing rod 13 and is threadedly connected to the threaded holes 14. A glue storage cavity 16 is provided on the inner wall of the slide rail 1. Several through holes 17 are provided on the inner walls of the front and rear sides of the slide rail 1. Dust plugs 18 are provided on the inner walls of the top left and right sides of the slide rail 1.

[0033] Specifically, the reinforcing rod 13 is made of high-strength aluminum alloy with a cross-sectional size of 15mm×10mm, a length adjustment range of 300~800mm, and a wall thickness of 2mm. It works together to enhance the lateral rigidity of the frame 2 and improve its resistance to deformation. The threaded hole 14 is adapted to the size of the bolt 15, providing a threaded connection point for fixing the sleeve 12 and the reinforcing rod 13, ensuring reliable locking. It allows the reinforcing rod 13 to slide and extend along the inner wall of the sleeve 12, flexibly adapting to frames 2 of different widths and improving the versatility of the components. The bolt 15 transmits the fastening force to lock the sleeve 12 and the reinforcing rod 13, preventing relative sliding during use and ensuring structural stability. The thread engagement between the bolt 15 and the threaded hole 14 enables detachable fixing, making it easy to adjust the extension length of the reinforcing rod 13 according to the width of the frame 2 and then lock it.

[0034] The glue storage cavity 16 stores lubricant or sealant, providing a continuous lubrication basis for the sliding of the slide rail 1 and the slider 3, while improving the sealing performance of the slide rail 1. The through hole 17 allows the glue in the glue storage cavity 16 to seep evenly to the inner wall of the slide rail 1, reducing the sliding friction of the slider 3 and ensuring smooth opening and closing. The dust plug 18 is used to seal the opening of the glue storage cavity 16 to prevent dust and impurities from entering and contaminating the glue or blocking the through hole 17, thus extending the service life of the slide rail 1. The reinforcing rod 13 is adjustable and easy to install and remove. The glue storage cavity 16 provides continuous lubrication and sealing, protects the slide rail from dust, extends its service life, and improves the overall practicality and durability.

[0035] Working principle: Based on the width of frame 2, push the reinforcing rod 13 to slide along the inner wall of sleeve 12 to the appropriate length, and screw the bolt 15 through sleeve 12 into the corresponding threaded hole 14 to lock the reinforcing rod 13 and sleeve 12. When installing frames 2 of different widths, align the beveled rear end of the connecting plate 11 with the insert rod 7, push the snap-fit ​​block 10 close to the fixing block 6, and the beveled guide will cause the insert rod 7 to slide along the inner wall of the fixing block 6 and compress the spring 9 until the snap hole is aligned with the insert rod 7. The elastic return force of the spring 9 is greater than the friction force of the insert rod 7, pushing the limiting plate 8 to drive the insert rod 7 into the snap hole. The fixing block 6 and the snap-fit ​​block 10 are firmly connected, and at the same time, they jointly fix the reinforcing rod 13 and strengthen the frame. The frame 2 has high rigidity and resistance to deformation. The glue storage cavity 16 of the slide rail 1 stores lubricant or sealant, which seeps evenly into the inner wall of the slide rail 1 through the through hole 17. The dust plug 18 seals the opening of the glue storage cavity 16 to prevent impurities from entering. The frame 2 is pushed, and the slider 3 slides along the inner wall of the slide rail 1. The seeping glue reduces sliding friction and ensures that the screen window opens and closes smoothly without jamming. The Q235 cold-rolled steel reinforcing rib 5 inside the frame 2 further enhances the resistance to deformation. When the length of the reinforcing rod 13 needs to be adjusted, the bolt 15 can be loosened for sliding adjustment. The main screen window 4 is fixed by high-strength laser welding to achieve insect prevention and ventilation functions. The overall structure takes into account stability, versatility and convenience, and extends the service life of the screen window.
