Description

Technical Field

[0001] This utility model relates to the technical field of screen windows, and in particular to an invisible screen window. Background Technology

[0002] Invisible screens are a modern insect-proof design. Referring to the utility model patent "A Labor-Saving Invisible Screen" (publication number CN221299034U), an invisible screen mainly includes a screen box, a screen mesh, a track, and a pull rod. The screen box contains a roller connected to one side of the screen mesh, and a spring is installed inside the roller. The other side of the screen mesh is connected to the pull rod. Its main feature is that it can be "hidden," maintaining the window's transparency and aesthetics. When in use, pulling the pull rod unfolds the screen mesh, and the mesh rewinds automatically thanks to the spring. Generally, a screen lock is required, such as magnetic blocks that attract each other on the pull rod and frame, or hook locks that are interlocked. When not in use, simply unlocking the screen mesh allows the spring-loaded roller to automatically rewind it back into the screen box.

[0003] However, this type of invisible screen structure has its shortcomings. For example, when it is first used, the spring force is relatively large, so the speed at which the screen is pulled back is too fast, which can easily injure the user and pose a safety hazard. After long-term use, the spring force becomes smaller, making it difficult to pull the screen, and the speed of retraction is slow or even incomplete. Part of the screen is still outside the screen box. If external force is used to push the screen at this time, it can easily damage the screen. Moreover, this invisible screen structure cannot be "stopped at any time". It only has two states: fully unfolded and retracted. Utility Model Content

[0004] The present invention provides an invisible screen window to solve the aforementioned technical problem of incomplete closure due to excessively fast or slow retraction speed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an invisible screen window, comprising a screen box, vertical profiles, a pull rod, a screen mesh, and two horizontal profiles. A roller is provided inside the screen box. One side of the screen mesh is connected to the roller, and the other side is connected to the pull rod. The screen window also includes a winding structure, which comprises a first winding wheel fixed to the end of the roller, a second winding wheel rotatably disposed at the end of the vertical profiles, a sealing member disposed at the end of the pull rod, and a strip-shaped object sequentially wound around the first winding wheel, the second winding wheel, and the sealing member. The two ends of the strip-shaped object are respectively connected to the first winding wheel and the sealing member.

[0006] Furthermore, the first winding wheel is fixed to the end of the reel, and the central axis of the first winding wheel corresponds to the central axis of the reel. The second winding wheel is rotatably mounted on the end of the vertical profile through a connector.

[0007] Furthermore, the central axes of the first winding wheel and the second winding wheel are perpendicular to each other.

[0008] Furthermore, the sealing member is provided with a mounting portion for installing strip-shaped objects.

[0009] Furthermore, the transverse profiles have cavities for the movement of the strips.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting up a winding structure, the strip is wound around the first winding wheel and the second winding wheel and connected to the sealing part. The strip drives the first winding wheel to rotate forward or backward, thereby realizing the unfolding or rewinding of the mesh. It can achieve the effect of "stopping as needed" and prevent the mesh from rewinding too fast or too slow, or from being incompletely rewound. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As shown in the attached diagram, this utility model discloses an invisible screen window, comprising a screen box 1, vertical profiles 2, a pull rod 3, a screen 4, and two horizontal profiles 5. The screen box 1, vertical profiles 2, and two horizontal profiles 5 form a frame structure. A roller 11 is provided inside the screen box 1. One side of the screen 4 is connected to the roller 11, and the other side is connected to the pull rod 3. The two horizontal profiles 5 are the upper rail profile and the lower rail profile, and a screen track 51 is also provided inside them. It should be noted that in order to provide sufficient space for the strip 104 to move, the length of the screen track 51 must be shorter than the horizontal profiles 5, and it is centered along the length direction of the horizontal profiles 5. It also includes a winding structure, which includes a first winding wheel 101 fixed to the end of the roller 11, a second winding wheel 102 rotatably disposed at the end of the vertical profile 2, a sealing member 103 disposed at the end of the pull rod 3, and a winding member sequentially wound around the first winding wheel 101 and the second winding wheel 102. The strip 104 of the sealing element 103 is connected at both ends to the first winding reel 101 and the sealing element 103, respectively. One end of the strip 104 is connected to the first winding reel 101 and wraps around the curved surface of the first winding reel 101, then wraps around the curved surface of the second winding reel 102, and finally connects to the sealing element 103, thereby forming a "J"-shaped distribution of strips 104, and a portion of the strip 104 is wrapped around the first winding reel 103. As shown in the figure, when the yarn 4 is in the unfolded state, part of the strip 104 is wound on the first winding wheel 101. When the yarn 4 is wound inside the yarn box 1, the strip 104 on the first winding wheel 101 is pulled out. That is, the "J" shape distribution gradually changes into a "U" shape distribution. It should be noted that the strip 104 has a certain rigidity and can be rolled up. Referring to a measuring tape, it can be made of plastic strips, metal strips, etc.

[0017] In one embodiment of an invisible screen window, a strip 104 is wound around a first winding wheel 101 and a second winding wheel 102, and connected to a sealing member 103, via a retractable structure. The strip 104 drives the first winding wheel 101 to rotate clockwise or counterclockwise. For example, moving the pull rod 3 towards the vertical profile 2 unfolds the screen 4. At this time, the sealing member 103 on the pull rod 3 pushes the strip 104 towards the second winding wheel 102. After passing around the second winding wheel 102, the strip 104 is pushed towards the first winding wheel 101, causing the first winding wheel 101 to rotate clockwise to retract the strip 104. Simultaneously, the reel 11 rotates clockwise to release the screen 4. Moving the pull rod 3 towards the screen box 1 retracts the screen 4. As the pull rod 3 moves, the sealing member 103... 3 drives the strip 104 to move, thereby gradually pulling out the strip 104 that is wound back on the first winding wheel 101, driving the first winding wheel 101 to reverse, and at the same time the roller 11 reverses to wind up the screen 4, thus effectively replacing the existing spring roller 11 structure, realizing the unfolding or winding of the screen 4, and the moving speed of the screen 4 corresponds to the speed at which the user pushes and pulls the lever 3, so that the moving speed of the screen 4 is controllable, preventing the screen 4 from winding back too fast or too slow, or incomplete winding, and can achieve the effect of "stopping on demand". At the same time, the winding structure can be installed at the top or bottom of the screen window. It is preferable to set two winding structures, distributed at the top and bottom of the screen window. Using two winding structures to drive the screen 4 at the same time can make the pushing and pulling of the screen 4 more stable.

[0018] In this embodiment, the first winding wheel 101 is fixed to the end of the reel 11, and the central axis of the first winding wheel 101 corresponds to the central axis of the reel 11. The second winding wheel 102 is rotatably mounted on the end of the vertical profile 2 via a connector 111. Specifically, the connector 111 has a shaft seat rotatably connected to the second winding wheel 102. Both the first winding wheel 101 and the second winding wheel 102 are equipped with connectors 111, and the first winding wheel 101 and the second winding wheel 102 are respectively rotatably connected to corresponding connectors 111. One of the connectors 111 is installed at the end of the yarn box 1. It can be installed on the top or bottom, or at both ends. The connector 111 has a bearing for rotatably connecting the first winding wheel 101. The connector 111 is rotatably connected to the first winding wheel 101 through the bearing. The first winding wheel 101 is fixed to the end of the reel 11. If only one first winding wheel 101 is used, it can only be installed at one end of the reel 11. In this case, to ensure the normal rotation of the reel 11, a bearing or other structure is required at the other end to connect the yarn box 1. Preferably, a two-winding structure is used, that is, two first winding wheels 101 are set and installed at both ends of the reel 11 respectively.

[0019] In this embodiment, the central axes of the first winding wheel 101 and the second winding wheel 102 are perpendicular. It should be noted that the strip 104 contacts the curved surface of the first winding wheel 101 / second winding wheel 102 through its plane. Since the pushing and pulling of the strip 104 is required to drive the yarn 4, the arrangement of the first winding wheel 101 and the second winding wheel 102 is such that the strip 104 wound on both is twisted to a certain extent, thereby enhancing the strength of the strip 104 and ensuring that the strip 104 can drive the yarn 4 to push and pull normally.

[0020] In this embodiment, the sealing member 103 is provided with a mounting part for mounting the strip 104. The end of the strip 104 can be directly fixed to the mounting part by screws. At the same time, a guide wheel can also be provided on the connecting plate. The guide wheel rotates on the connecting plate, and the central axis of the guide wheel is parallel to the central axis of the second winding wheel 102. The guide wheel guides the strip 104.

[0021] In this embodiment, the horizontal profile 5 has a cavity 50 for the movement of the strip 104. Since the strip 104 needs to be wound around the first winding wheel 101, the second winding wheel 102 and the sealing member 103, that is, it needs to span across the horizontal profile 5, the horizontal profile 5 is used to hide the strip 104. The cavity 50 provided in the horizontal profile 5 is mainly used for the movement of the strip 104, and the mesh track 51 is provided on one side inside the cavity 50.

[0022] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
