Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, specifically a concealed screen window with a pressure strip structure. Background Technology

[0002] A window screen is a device installed on a window to block insects, dust, and other pollutants from entering the room while allowing ventilation. It typically consists of a mesh screen and a frame. The mesh screen is the core component, serving to filter and block pollutants; the frame secures the mesh screen and ensures a tight fit against the window.

[0003] With the increasing demands for aesthetics and functionality in the building doors and windows industry, concealed screen windows, due to their retractable screen design, have gradually become the mainstream product in the market. Traditional concealed screen windows mainly adopt two structural forms:

[0004] External pressure strip type: A plastic or metal pressure strip is set on the surface of the screen frame, and the screen is fixed by screws or clips. This structure causes the pressure strip to protrude 0.5 to 1.2 cm when the screen is opened, which destroys the integrity of the window frame plane and contradicts the "invisible" design concept; at the same time, replacing the screen requires disassembling all the fixing parts.

[0005] Adhesive sealing type: The edges of the mesh are glued to the groove of the frame with double-sided tape. Although this achieves a flush surface, there is a problem of adhesive aging and failure. Under high temperature conditions, the adhesive strength decreases, causing the mesh to loosen and mosquitoes to invade. Moreover, the residual adhesive must be thoroughly removed when replacing it, resulting in a poor user experience. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a concealed screen window with a pressure strip structure, so as to solve the problems of poor stability and unsightly appearance of traditional concealed screen windows after they are fixed.

[0007] A concealed screen window with a pressure strip structure includes a window frame. The interior of the window frame is equipped with a first screen mesh with upper and lower layers. A second screen mesh is provided between the two first screen meshes. The second screen mesh is an invisible screen mesh. The back of the window frame is provided with a storage groove around the first screen mesh. The back of the window frame is provided with a limiting frame installed in the storage groove. The limiting frame only fits against the mounting surface of the storage groove, and there are gaps on the other surfaces. The first screen mesh is pressed into the storage groove.

[0008] It also includes a pressure strip, which is pressed into the storage groove to hold down the first mesh, and the second mesh is movably connected to the window frame, and a protective component is provided on the back of the window frame.

[0009] Preferably, the window frame has a horizontal mounting part inside, and the front end face of the window frame has limiting strips on the left and right sides, and the vertical cross section of the limiting strips is "T" shaped.

[0010] Preferably, the window frame has an internal mounting frame, the second screen is installed inside the mounting frame, and the front end of the mounting frame has a symmetrical mating groove that cooperates with the limiting strip.

[0011] Preferably, the front end face of the mounting frame is provided with a single-pin lock near the bottom, and the single-pin lock is locked into the mounting part.

[0012] Preferably, the bottom front end of the first mesh of the lower layer is provided with a metal spring pin, which is symmetrically installed inside the window frame and extends outwards respectively.

[0013] Preferably, the protective component includes a rotating shaft, a protective frame, and a protective plate. The rotating shaft is fixedly connected to the window frame near the top and extends from the inside of the window frame at both ends. The vertical cross-sectional profile of the protective frame is "U"-shaped, and the two ends of the rotating shaft are rotatably connected inside the protective frame.

[0014] Preferably, the protective plates are fixedly connected inside the protective frame and are distributed in an alternating pattern, and the metal spring pins extend and are inserted into the protective frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model features a window frame with a first screen installed inside. The first screen is arranged in layers at intervals. A storage groove is set on the back of the window frame, and a limiting strip is fixedly connected to the top of the storage groove. First, the four sides of the first screen are pressed into the storage groove. Then, the limiting strip is placed in the gap between the storage groove and the limiting frame. Since the width of the limiting strip is greater than the gap between the limiting frame and the storage groove, it will be squeezed when pressed into the storage groove and finally enter the storage groove to fix the first screen. The limiting strip is firmly fixed in the storage groove through interference fit. On the one hand, it hides the screen and improves the aesthetics. On the other hand, the installation method is simple and stable.

[0017] Furthermore, a second screen is installed between the two first screens. This second screen is an invisible screen and is movably connected within the window frame. Pushing the second screen to open and close it allows for the opening and closing of the screen window, improving flexibility. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1: This utility model provides a concealed screen window with a pressure strip 6 structure, including a window frame 1. The inside of the window frame 1 is installed with upper and lower layered first screens 2. A second screen 3 is provided between the two first screens 2. The second screen 3 is an invisible screen. The back of the window frame 1 and around the first screens 2 are provided with storage grooves 4. The back of the window frame 1 is provided with a limiting frame 5 installed in the storage grooves 4. The limiting frame 5 is only in contact with the mounting surface of the storage grooves 4, and there are gaps on the other surfaces. The first screens 2 are pressed into the storage grooves 4.

[0028] It also includes a pressure strip 6, which is pressed into the storage groove 4 to press down the first screen 2, and the second screen 3 is movably connected to the window frame 1. The back of the window frame 1 is provided with a protective component.

[0029] It should be noted that the window frame 1 is designed with a first screen 2 installed inside. The first screen 2 is arranged in layers at intervals. A storage groove 4 is set on the back of the window frame 1. A limiting strip 7 is fixedly connected to the top of the storage groove 4. First, the four sides of the first screen 2 are pressed into the storage groove 4. Then, the pressure strip 6 is placed in the gap between the storage groove 4 and the limiting frame 5. Since the width of the pressure strip 6 is larger than the gap between the limiting frame 5 and the storage groove 4, it will be squeezed when pressed into the storage groove 4. Finally, it enters the storage groove 4 to fix the first screen 2. The pressure strip 6 is firmly fixed in the storage groove 4 through interference fit. On the one hand, it hides the screen 2 and improves the aesthetics. On the other hand, the installation method is simple and stable.

[0030] Furthermore, a second screen 3 is installed between the two first screens 2. The second screen 3 is an invisible screen and is movably connected inside the window frame 1. Pushing the second screen 3 to open and close the screen window can realize the opening and closing of the screen window, improving flexibility.

[0031] Furthermore, the limiting strip 7 can be integrally formed with the window frame 1, improving its sturdiness. The pressure strip 6 is made of elastic rubber material (such as EPDM), and its cross-section is trapezoidal. The top width is 1.0 to 1.5 mm larger than the gap between the limiting frame 5 and the storage groove 4. When pressed in, the pressure strip 6 is deformed by compression and then embedded into the gap. It tightly presses the first screen 2 with its elastic restoring force. Before pressing the first screen 2 and the pressure strip 6 into the storage groove 4, clamps can be used to fix the window frame 1 from both sides. Then, the pressure roller is used to press the first screen 2 and the pressure strip 6 into the storage groove 4 along the direction of the storage groove 4, thereby improving the installation efficiency of the first screen 2 and the pressure strip 6.

[0032] In this embodiment, the window frame 1 has a horizontal mounting part 101 inside, and the front end face of the window frame 1 has a limiting strip 7 on the left and right sides, and the vertical section of the limiting strip 7 is "T" shaped.

[0033] In this embodiment, the window frame 1 is provided with an installation frame 8 inside, the second screen 3 is installed inside the installation frame 8, and the front end of the installation frame 8 is provided with a mating groove 9, which cooperates with the limiting strip 7.

[0034] It should be noted that the limiting strip 7 is fixedly connected to the front end of the window frame 1, and a mating groove 9 is set on the mounting frame 8. The mating groove 9 and the "T"-shaped vertical section of the limiting strip 7 cooperate with each other, and the horizontal section of the "T"-shaped side of the limiting strip 7 extends to the front end of the mounting frame 8, thereby improving the stability of the movement of the second screen 3 during the movement of the second screen 3.

[0035] In this embodiment, a single-pin lock 10 is provided on the front end face of the mounting frame 8 near the bottom position, and the single-pin lock 10 is locked into the mounting part 101.

[0036] It should be noted that the mounting part 101 is horizontally fixed inside the window frame 1. A single-cylinder lock 10 is set at the bottom of the front end face of the mounting frame 8. The single-cylinder lock 10 cooperates with the mounting part 101, so that when the second screen 3 is closed, the second screen 3 can be fixed by the single-cylinder lock 10, thereby improving security.

[0037] In this embodiment, the bottom front end of the lower first mesh 2 is provided with a metal spring pin 11, which is symmetrically installed inside the window frame 1 and extends outwards respectively.

[0038] It should be noted that the metal spring pin 11 is a commonly used locking device on windows, which will not be elaborated on here. After the protective components are installed, the window frame 1 can be fixedly connected by inserting the metal spring pin 11 into the protective plate 14.

[0039] In this embodiment, the protective component includes a rotating shaft 12, a protective frame 13, and a protective plate 14. The rotating shaft 12 is fixedly connected to the window frame 1 near the top and extends from the inside of the window frame 1 at both ends. The vertical cross-sectional profile of the protective frame 13 is "U" shaped, and the two ends of the rotating shaft 12 are rotatably connected inside the protective frame 13.

[0040] It should be noted that, with the protective components in place, after the protective components are installed, the window frame 1 is no longer fixed to the wall, and the protective frame 13 is fixedly installed inside the wall. The window frame 1 and the protective frame 13 are connected by a rotating shaft 12, which allows the window frame 1 to rotate inside the protective frame 13. After the metal spring pin 11 is disengaged from the protective frame 13, the window frame 1 can be pushed outward, which facilitates the cleaning of the first screen 2 and the second screen 3 and improves the subsequent maintenance effect on the first screen 2 and the second screen 3.

[0041] In this embodiment, the protective plate 14 is fixedly connected inside the protective frame 13 and is distributed in an alternating manner, and the metal spring pin 11 extends and is inserted into the protective frame 13.

[0042] It should be noted that the protective plate 14 is fixedly connected inside the protective frame 13 and is distributed alternately. Thus, when the second screen 3 is in the open state, the external protective plate 14 is also provided to protect the gap of the open second screen 3, which further improves the safety of the invisible screen window.
