Description

Technical Field

[0001] This utility model relates to the field of screen technology, and in particular to a retractable screen. Background Technology

[0002] Traditional window screens are mostly fixed or sliding, with the screen mesh constantly exposed on the outside of the window frame, which can obstruct indoor airflow and affect the view. Therefore, retractable window screens are gradually appearing on the market, allowing the screen mesh to be opened or closed according to different usage scenarios.

[0003] Currently, most retractable screen windows are roll-up screen windows. The core components of roll-up screen windows, such as the roller and spiral spring, are integrated with the screen window frame. Therefore, when it is necessary to clean the screen mesh, the entire screen window still needs to be separated from the window frame, making it more cumbersome for users to clean this type of screen window.

[0004] Therefore, we need to develop a screen structure that combines concealed storage and modular disassembly to make it easier for users to clean the screen mesh. Utility Model Content

At least a portion of the upper and lower edges of the mesh are located in the first limiting grooves of the two horizontal bars. The upper edge portion and the lower edge portion are slidably inserted into the second limiting grooves of the two horizontal bars, thereby limiting the mesh in the length direction of the first vertical bar through the upper edge portion and the lower edge portion.

Detailed Implementation

[0017] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0018] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 9 As shown, this embodiment of the utility model provides a retractable screen window, including a retractor with at least one roller 1. As prior art, the roller 1 is the core component for the automatic retraction function of the screen window, and it typically contains a spiral spring (not shown in the figure). When the screen 3 is pulled out, the spiral spring deforms and stores elastic potential energy. When the external force disappears, the elastic potential energy is released, driving the roller 1 to rotate, causing the screen 3 to smoothly and orderly retract back into the roller 1.

[0020] The concealed screen window also includes a rectangular frame 2 and a screen 3. The rectangular frame 2 includes two horizontal bars 21 and a first vertical bar 22 and a second vertical bar 23. The upper and lower ends of the second vertical bar 23 are fixedly connected to the right ends of the two horizontal bars 21, respectively. The upper and lower ends of the first vertical bar 22 are detachably connected to the left ends of the two horizontal bars 21, respectively. The first vertical bar 22 is hollow inside and has a vertical opening 221 on the side facing the second vertical bar 23. Each of the two horizontal bars 21 has a groove 211 extending along its length on its opposite side. The roller 1 is rotatably connected to the first horizontal bar 21. The first vertical rod 22 is installed inside and in the same direction as the first vertical rod 22. The left end of the mesh 3 passes through the vertical opening 221 into the first vertical rod 22 and is fixed to the roller 1 so that the mesh 3 can be wound up by the winder. The right end of the mesh 3 is equipped with a first connector 4. The upper and lower ends of the first connector 4 are slidably connected to the grooves 211 on the two horizontal rods 21, respectively. A second connector 5 is installed on the second vertical rod 23. When the mesh 3 is fully opened, the first connector 4 and the second connector 5 are detachably connected. A handle 44 can also be fixedly installed on the first connector 4. The handle 44 makes it easy for the user to pull the first connector 4 to open and close the mesh 3.

[0021] It should be noted that the concealed screen is fixedly installed on the window frame. Specifically, the crossbar 21 is also provided with a fixing threaded hole 217. The rectangular frame 2 can be threaded onto the window frame by passing bolts through the fixing threaded hole 217, so as to realize the fixed connection between the concealed screen and the window frame.

[0022] In this embodiment, the concealed screen window uses a retractor (which is existing technology and includes a roller 1 and a spiral spring) to automatically retract the screen 3, and combines it with a detachable frame structure to achieve convenient disassembly and cleaning.

[0023] When the mesh 3 is unfolded: an external force pulls the first connecting piece 4 on the right side of the mesh 3, causing it to slide along the groove 211 of the horizontal bar 21 towards the second vertical bar 23. At this time, the spiral spring inside the roll 1 deforms and stores energy. After being fully unfolded, the first connecting piece 4 locks with the second connecting piece 5 on the second vertical bar 23, and the mesh 3 remains in the unfolded state. The groove 211 restricts the unfolding / rewinding path of the mesh 3 to prevent deviation or wrinkles.

[0024] When the mesh 3 is rolled up: the locking of the first connecting piece 4 and the second connecting piece 5 is released, the spiral spring releases its elastic potential energy, drives the roller 1 to rotate, and the mesh 3 automatically rolls back into the first vertical rod 22.

[0025] When disassembling and cleaning the mesh 3: disconnect the connection between the first vertical rod 22 and the horizontal rod 21, and remove the first vertical rod 22, which is wrapped with the mesh 3, as a whole; after pulling out the mesh 3 for cleaning, fix the first vertical rod 22 and the horizontal rod 21 again to complete the reset.

[0026] In summary, this concealed screen window, with its retractor, eliminates the need for manual retraction; the screen 3 automatically retracts after the external force is removed, improving ease of use. The screen 3 is retracted within the first vertical bar 22, concealing itself when not in use, saving space and keeping the window frame tidy. The first vertical bar 22 is detachably connected to the left end of the horizontal bar 21, allowing for easy cleaning of the screen 3 without disassembling the entire screen window; simply separating the first vertical bar 22 is sufficient to remove the screen 3, solving the problem of traditional screen windows requiring complete disassembly for cleaning. Simultaneously, the retractor can be removed along with the first vertical bar 22, facilitating individual repair or replacement of components.

[0027] In some practical applications, refer to Figure 4 , Figure 5 and Figure 8 As shown, the bottom surface of the sliding grooves 211 of the two crossbars 21 is provided with a first limiting groove 212 that extends through the corresponding crossbar 21 along the length direction of the crossbar 21, and a second limiting groove 213 that communicates with the first limiting groove 212. The second limiting groove 213 is located on the side of the first limiting groove 212 away from the sliding groove 211. The upper and lower edges of the mesh 3 are both edged to form an upper edge portion 31 and a lower edge portion 32. The material can be rigid or semi-rigid (such as plastic strips or metal strips), which cooperate with the second limiting groove 213. At least a portion of the upper and lower ends of the mesh 3 are respectively located in the first limiting grooves 212 of the two crossbars 21. The upper edge portion 31 and the lower edge portion 32 are respectively slidably inserted into the second limiting grooves 213 of the two crossbars 21, thereby limiting the mesh 3 in the length direction of the first vertical bar 22 through the upper edge portion 31 and the lower edge portion 32.

[0028] In this embodiment, the first limiting groove 212 is provided through the length of the crossbar 21, and the upper and lower edge portions of the mesh 3 are located in the groove, forming a lateral guide. The second limiting groove 213 is connected to the first limiting groove 212 and is located on the side away from the slide groove 211. The upper edge portion 31 and the lower edge portion 32 of the mesh 3 are slidably inserted therein to achieve longitudinal limiting.

[0029] The upper edge portion 31 and the lower edge portion 32 are embedded in the second limiting groove 213 to restrict the swaying of the mesh 3 in the vertical direction (the length direction of the first vertical rod 22), preventing the edges of the mesh 3 from lifting due to wind or external force, ensuring that the mesh 3 fits tightly with the rectangular frame 2, and improving the mosquito and dust prevention effect. The first limiting groove 212 and the second limiting groove 213 cooperate to double-constrain the sliding path of the mesh 3, preventing the mesh 3 from shifting left and right or wrinkling during unfolding / rolling, and ensuring that the surface of the mesh 3 is flat.

[0030] In addition, the upper edge 31 and the lower edge 32 can enhance the rigidity of the edge of the mesh 3, so that the force is more even when the mesh 3 is pulled, and local tearing is avoided (especially for thin mesh 3 materials).

[0031] In summary, the newly added first limiting groove 212 and second limiting groove 213, along with the edge-wrapping design, work synergistically with the original detachable first vertical rod 22 and automatic winding system. While maintaining the advantages of convenient disassembly and cleaning, it also solves the problems of easy displacement and poor sealing of traditional concealed screen windows. In some practical applications, based on any of the above embodiments, the detachable connection between the first vertical bar 22 and the two horizontal bars 21 can at least adopt the following connection methods: First connection method: Refer to Figures 5 to 6 As shown, the first vertical rod 22 has a plane 222 on the side near the second vertical rod 23. Two first inserts 223 are arranged vertically opposite each other on the plane 222. Each first insert 223 has a first threaded hole 2231. The left end of each of the two horizontal rods 21 has a first slot 214 and a second threaded hole 215. The two first inserts 223 are respectively inserted into the first slots 214 of the two horizontal rods 21, and the two first threaded holes 2231 are respectively coaxially opposite to the two second threaded holes 215. Each set of corresponding first threaded holes 2231 and second threaded holes 215 is threaded with bolts to fix the first vertical rod 22.

[0032] Second connection method: Refer to Figure 9As shown, the first vertical rod 22 has a plane 222 on the side near the second vertical rod 23. Two first insert blocks 223 are arranged vertically opposite each other on the plane 222. Each first insert block 223 has a first insertion hole 2232. The left ends of the two horizontal rods 21 are provided with a first slot 214 and a second insertion hole 216. The two first insert blocks 223 are respectively inserted into the first slots 214 of the two horizontal rods 21, and the two first insertion holes 2232 are respectively coaxially opposite to the two second insertion holes 216. Each pair of corresponding first insertion holes 2232 and second insertion holes 216 are fixed by a quick-locking pin.

[0033] Bolt threaded connections provide rigid fixation, strong resistance to vibration and wind, and are suitable for long-term fixed installations. Quick-lock pins (an existing technology in the mechanical field) provide mechanical locking, with a connection strength slightly lower than bolts, but still meet daily use needs and are suitable for scenarios requiring frequent disassembly.

[0034] In other practical applications, refer to Figures 7 to 8 As shown, the first connector 4 includes a longitudinally arranged main body 41 and two sliders 42 located at the upper and lower ends of the main body 41, respectively. The two sliders 42 are slidably connected to the grooves 211 of the two crossbars 21. The main body 41 has a fixed vertical groove 411 arranged along its length direction. The right side end of the mesh 3 is fixedly connected to the fixed vertical groove 411 to ensure that the edge of the mesh 3 is flat and wrinkle-free.

[0035] Specifically, a flat surface 222 is formed on the side of the first vertical rod 22 near the second vertical rod 23. A rubber pad 24 is fixedly embedded in the flat surface 222. When the mesh 3 is fully retracted, the main body part 41 abuts against the rubber pad 24. When the mesh 3 is fully retracted, the main body part 41 abuts against the rubber pad 24, forming a flexible contact. The rubber pad 24 absorbs the impact force at the winding end through elastic deformation.

[0036] In some practical applications, refer to Figure 2 and Figure 7 As shown, the connection between the first connector 4 and the second connector 5 is as follows: at least one first magnet 43 is fixedly embedded in the first connector 4, and at least one second magnet 51 is fixedly embedded in the second connector 5; when the mesh 3 is fully extended, the first magnet 43 is magnetically attracted to the second magnet 51. Alternatively, the connection between the first connector 4 and the second connector 5 can also be achieved using a pre-existing latch button, whereby the latch automatically locks when the first connector 4 contacts the second connector 5, and unlocking requires pressing the button.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
