Description

Technical Field

[0001] This invention relates to the field of screen technology, and in particular to a magnetic screen frame strip that is easy to install. Background Technology

[0002] As an essential household item for preventing mosquitoes and other insects in summer, the ease of installation and structural stability of window screens directly affect the user experience. Traditional window screen frames mostly use slotted or adhesive fixing, which has problems such as cumbersome installation, inconvenient disassembly, and easy loosening and deformation after long-term use. Magnetic window screen frames are gradually becoming the mainstream in the market due to their advantages of not requiring drilling and being able to be quickly disassembled and cleaned.

[0003] In existing technologies, there are generally two installation methods for assembling magnetic frame strips and screens. The first method involves attaching adhesive magnetic strips and decorative strips to both sides of the screen. The adhesive magnetic strips are used for magnetic attraction, while the decorative strips are for aesthetic purposes. However, after prolonged use, both the adhesive magnetic strips and decorative strips are prone to oxidation and delamination, eventually detaching from the screen and resulting in insecure fixation. The second method is an assemblable magnetic screen disclosed in Chinese Patent CN200820170782.3. In this design, a slot is created on the rubber magnetic strip, and a PE plastic clip is directly inserted into the slot. The screen is then pressed between the contact surfaces of the PE clip and the magnetic strip, thus achieving fixation. While this structure simplifies component composition, it has significant performance defects during actual installation and use, especially in the screen installation stage, causing considerable inconvenience to users. First, magnetic strips are mostly made of rubber, which has some elasticity but a high coefficient of friction. PE clips, on the other hand, are made of hard plastic with a smooth surface and a low coefficient of friction. This difference in material properties makes the force applied when inserting the PE clip into the magnetic strip slot, especially when a mesh is held between the PE clip and the magnetic strip, extremely unstable. On one hand, the elasticity of the rubber magnetic strip causes slight fluctuations in the slot size, making it difficult to precisely align the PE clip. On the other hand, the high-friction rubber surface is prone to slippage or jamming when in contact with the low-friction PE surface, requiring users to repeatedly adjust the angle and force to successfully push the PE clip into the slot, resulting in low installation efficiency.

[0004] Secondly, during installation, users often need to apply significant external force to smoothly insert the PE card strip along with part of the mesh into the magnetic strip slot. Due to the substantial difference in hardness between the rubber magnetic strip and the PE card strip, this external force acts directly on the contact area, easily causing the PE card strip to break or deform, or the magnetic strip slot to crack or wear. Especially in low-temperature environments, the elasticity of the rubber magnetic strip decreases, and the brittleness of the PE card strip increases, further increasing the probability of component damage. This not only increases installation costs but also reduces product reliability.

[0005] Therefore, the above installation method is difficult and laborious for fixing and installing mesh screens, and the product is also easily damaged during the installation process.

[0006] In summary, all similar magnetic frame strips currently on the market have certain problems and need to be improved. Summary of the Invention

[0007] To address the aforementioned problems, this invention proposes a magnetic window screen frame strip that is easy to install.

[0008] The technical solution adopted in this invention is: a magnetic window screen frame strip that is easy to install, comprising: The first magnetic strip is used to cooperate with the second magnetic strip, which is magnetically installed on one side of the window frame. A middle locking strip is installed in front of the first magnetic strip, and a first locking structure is provided between the middle locking strip and the first magnetic strip; A decorative clip is installed in front of the middle clip to help hold the mesh between the middle clip and the decorative clip. A second snap-fit ​​structure is provided between the middle clip and the decorative clip. The first magnetic strip is made of rubber magnetic material, while the middle card strip and the decorative card strip are both made of plastic.

[0009] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0010] Preferably, the second snap-fit ​​structure includes: The second slot is located on the front side of the middle card strip; A snap-fit ​​element, disposed on the rear side of the decorative clip, is used to engage at least a portion of the mesh into the second slot.

[0011] Preferably, the second snap-fit ​​structure further includes second limiting strips respectively disposed on the upper and lower sides of the inner wall of the second slot. The snap-fit ​​component includes two protruding strips, both of which extend in an inclined manner and form a gap that gradually widens from front to back between them. The ends of the protruding strips are provided with barbs, which abut against the second limiting strips to prevent the protruding strips from disengaging from the second slot. At least a portion of the mesh is squeezed into the second slot by the two protruding strips.

[0012] Preferably, the front side of the second limiting strip and the rear side of the barb portion both have an arc-shaped transition.

[0013] Preferably, the first snap-fit ​​structure includes: Two strips are fixed to the front side of the first magnetic strip at an interval, one above the other. The strips are provided with slots, and a groove is formed between the two strips. Two first slots are arranged vertically at intervals on the rear side of the middle retaining strip. A first limiting strip is provided on one side of the inner wall of the first slot. A flange is formed between the two first slots. The second slot is disposed in the flange. The strip is used to cooperate in the first slot. The flange is used to cooperate in the groove. The first limiting strip is used to cooperate in the retaining groove.

[0014] Preferably, both the card slot and the first limiting strip are arranged obliquely to the forward side.

[0015] More preferably, the projection of the decorative strip along the front-to-back direction completely covers the first magnetic strip, the second magnetic strip, and the intermediate strip.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Both the intermediate and decorative clips are made of plastic. Compared to the traditional heterogeneous combination of "rubber magnetic strip + PE clip," the friction coefficients of the intermediate and decorative clips, made of the same material, are closer, resulting in a higher degree of physical property matching. When installing the mesh, since the mesh is installed between the intermediate and decorative clips, and the materials of the intermediate and decorative clips are identical, their stress deformation patterns are consistent. Operators can quickly position and clamp the mesh by applying force evenly, without repeatedly adjusting the force to adapt to the deformation differences of different materials, or repeatedly adjusting the installation angle. This makes installation more convenient and labor-saving, reducing installation difficulty. 2. Since both protrusions extend at an angle and form a gap that gradually widens from front to back, the two protrusions will deform under pressure during the installation of the protrusions into the second groove. After the barb is fully inserted into the second groove, the two protrusions will return to their original shape, thus ensuring that part of the mesh is firmly installed in the second groove. The mesh is not easy to fall out of the second groove, and the overall structure is more stable. Attached Figure Description

[0023] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0024] Detailed implementation plan: See below Figures 1-7 This invention is a magnetic window screen frame strip that is easy to install, comprising: The first magnetic strip 1 is used to cooperate with the second magnetic strip 5, which is magnetically installed on one side of the window frame 6; The middle card strip 2 is installed in front of the first magnetic strip 1, and a first snap-fit ​​structure is provided between the middle card strip 2 and the first magnetic strip 1; Decorative clip 3 is installed in front of the middle clip 2 to help clamp the mesh 4 between the middle clip 2 and the decorative clip 3. A second snap-fit ​​structure is provided between the middle clip 2 and the decorative clip 3. The first magnetic strip 1 is made of rubber magnetic material, while the middle strip 2 and the decorative strip 3 are both made of plastic.

[0025] In a preferred embodiment of this invention, the intermediate clip 2 and the decorative clip 3 can be made of plastic materials with good aging resistance, such as PE, PVC, and ABS. Furthermore, to reduce logistics costs, the thickness and hardness of the intermediate clip 2 and the decorative clip 3 are typically low, allowing them to be rolled into a single bundle while ensuring stable interlocking.

[0026] Then, please see Figures 1-4 ,as well as Figure 7 As can be seen, in this embodiment, the second snap-fit ​​structure includes: The second slot 22 is located on the front side of the middle retaining strip 2; A snap-fit ​​element is provided on the rear side of the decorative snap-fit ​​strip 3, used to engage at least a portion of the mesh 4 into the second slot 22.

[0027] In addition, in this embodiment, the second snap-fit ​​structure also includes second limiting strips 24 respectively disposed on the upper and lower sides of the inner wall of the second slot 22. The snap-fit ​​component includes two protrusions 31, both of which extend in an inclined manner and form a gap that gradually widens from front to back between them. The ends of the protrusions 31 are provided with barbs 32, and the barbs 32 and the second limiting strips 24 abut against each other to prevent the protrusions 31 from disengaging from the second slot 22. At least part of the mesh 4 is squeezed into the second slot 22 by the two protrusions 31.

[0028] Here, when it is necessary to clamp the mesh 4 between the middle clip 2 and the decorative clip 3, firstly, align the two protruding strips 31 located on the rear side of the decorative clip 3 with the first slot 21 on the middle clip 2 and insert them. Since the two protruding strips 31 extend at an angle and the gap gradually widens from front to back, the protruding strips 31 will gradually close during the insertion process to smoothly insert into the second slot 22. After the barb 32 is fully inserted into the second slot 22, it will abut against the second limiting strip 24 to effectively prevent the protruding strips 31 from disengaging forward from the second slot 22.

[0029] In addition, in order to facilitate the smooth passage of the barb 32 and make the two protrusions 31 close together, in this embodiment, the front side of the second limiting strip 24 and the rear side of the barb 32 are both arc-shaped transitions.

[0030] After the middle clip 2 and decorative clip 3 are assembled, part of the mesh 4 will be squeezed into the second slot 22 along with the protrusion 31 and the barb 32, thereby ensuring that part of the mesh 4 is firmly installed in the second slot 22, and the mesh 4 is not easy to detach from the second slot 22, making the overall structure more stable.

[0031] Next, in this embodiment, the first snap-fit ​​structure includes: Two strips are fixed to the front side of the first magnetic strip 1 at an interval between the top and bottom. The strips are provided with slots 12 and a groove 13 is formed between the two strips. Two first slots 21 are arranged vertically at intervals on the rear side of the middle retaining strip 2. A first limiting strip 23 is provided on one side of the inner wall of the first slot 21. A flange is formed between the two first slots 21. A second slot 22 is set in the flange. The strip is used to fit in the first slot 21. The flange is used to fit in the groove 13. The first limiting strip 23 is used to fit into the retaining groove 12.

[0032] Then, in this embodiment, both the slot 12 and the first limiting strip 23 are arranged obliquely to the forward side.

[0033] Here, when assembling the first magnetic strip 1 and the intermediate retaining strip 2, the two strips on the front side of the first magnetic strip 1 are aligned with the two first slots 21 on the rear side of the intermediate retaining strip 2. Since the intermediate retaining strip 2 is made of plastic, it will deform slightly. With a little force, the strips can be inserted into the first slots 21 until the first limiting strip 23 is engaged in the retaining groove 12. At the same time, the flange of the intermediate retaining strip 2 is inserted into the groove 13 between the two strips, completing the engagement of the first magnetic strip 1 and the intermediate retaining strip 2. Since the retaining groove 12 and the first limiting strip 23 are both arranged at an angle to the front, the tightness of the engagement is increased, effectively preventing loosening or displacement between the intermediate retaining strip 2 and the first magnetic strip 1.

[0034] More specifically, the projection of the decorative card strip 3 along the front-to-back direction completely covers the first magnetic strip 1, the second magnetic strip 5, and the middle card strip 2.

[0035] Please see Figure 3 In this embodiment, the installed screen window magnetic frame strip is magnetically attached to the second magnetic strip 5 located on one side of the window frame 6 via the first magnetic strip 1, thus completing the installation of the screen window. The projection of the decorative strip 3 along the front-to-back direction completely covers the first magnetic strip 1, the second magnetic strip 5, and the middle strip 2, effectively concealing the internal structure and making the overall appearance of the screen window neater and more beautiful.

[0036] It is important to emphasize that the core principle of this application is as follows: both the intermediate clip 2 and the decorative clip 3 are made of plastic. Compared with the traditional heterogeneous combination of "rubber magnetic strip + PE clip", the intermediate clip 2 and the decorative clip 3, made of the same material, have a closer coefficient of friction and a higher degree of physical performance matching. When installing the mesh 4, since the mesh 4 is installed between the intermediate clip 2 and the decorative clip 3, and the intermediate clip 2 and the decorative clip 3 are made of the same material and have the same deformation law under force, the operator can quickly complete the positioning and clamping of the mesh 4 by applying force evenly. There is no need to repeatedly adjust the force to adapt to the deformation difference of different materials, nor is there a need to repeatedly adjust the installation angle, making the installation more convenient and labor-saving, and reducing the installation difficulty.
