Description

Technical Field

[0001] This utility model relates to the technical field of screen doors and windows, and in particular to a screen tensioning structure for invisible screen doors and windows. Background Technology

[0002] In recent years, with the increasing demand for comfortable living environments and mosquito prevention, invisible screen doors and windows, or fabric partitions, have been widely used in the field of building doors and windows. Invisible screen doors and windows typically include main components such as a screen box, upper track, lower track, handle rod, and screen mesh. Their main feature is that the screen mesh can be "hidden" inside the screen box. The top and bottom edges of the screen mesh are slidably set within the upper and lower tracks, which guide the sliding unfolding and retracting of the screen mesh. When people want to unfold the screen mesh, they can pull it out through the handle rod. The screen mesh slides along the upper and lower tracks to the side away from the screen box and is then fixed with a lock. To ensure that the screen mesh is taut, it needs to be cut according to the distance between the upper and lower tracks during installation. At the same time, the screen mesh needs to be taut and placed within the upper and lower tracks during installation. Therefore, the size requirements for the screen mesh are high, which makes the installation of screen doors, screen windows, or fabric partitions troublesome. In addition, the screen mesh is prone to loosening during use or under the influence of external forces. Summary of the Invention

[0016] 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.

[0017] As shown in the attached diagram, this utility model discloses a mesh tensioning structure for an invisible screen door / window, comprising a mesh 1, a lower rail 2, and an upper rail 3. The lower edge of the mesh 1 is slidably connected to the lower rail 2. It also includes existing invisible screen door / window structures, specifically a screen box, a handle rod 4, and side profiles. The screen box, upper rail 3, lower rail 2, and side profiles form an outer frame. The handle rod 4 slides on the upper rail 3 and lower rail 2. One side of the mesh 1 is connected to a roller inside the screen box, and the other side is connected to the handle rod 4, with its lower edge sliding on the lower rail 2. These are all existing structures for invisible screen doors / windows. It should be noted that the upper edge of the mesh 1 is achieved by setting the upper rail 3 as a junction between the outer profile 31 and the mesh guide profile 32. The structure includes an outer profile 31 with a downward-facing groove 310. A sliding yarn guide 32 is provided within the groove 310. The upper edge of the yarn mesh 1 is slidably disposed within the yarn guide 32. An elastic traction component 33 for lifting the yarn guide 32 is provided inside the groove 310. The outer profile 31 lifts the yarn guide 32 through the elastic traction component 33, maintaining an upward force on the yarn guide 32. The lower edge of the yarn mesh 1 is slidably connected to the lower rail 2, and the upper edge is slidably connected to the yarn guide 32. Thus, the elastic traction component 33 can lift the yarn mesh 1 upward, keeping the yarn mesh 1 in a taut state.

[0018] This utility model discloses a mesh tensioning structure for invisible screen doors and windows. This structure can be applied to invisible screen doors, invisible screen windows, or fabric partitions. By setting the upper rail 3 as a split structure of outer profile 31 and mesh guide profile 32, the mesh 1 is connected by the mesh guide profile 32. The mesh guide profile 32 can slide up and down within the outer profile 31, and the outer profile 31 pulls the mesh guide profile 32 upward through the set elastic traction component 33, thereby ensuring that the mesh 1 remains taut. It can also improve the error tolerance of mesh 1 cutting, facilitate the installation of screen doors, screen windows, or fabric partitions, and prevent mesh 1 from loosening. It can automatically tension and straighten the mesh 1.

[0019] Specifically, the outer profile 31 has C-shaped grooves 300 symmetrically arranged on both sides of the groove opening of the groove 310 for the sliding of the hanging wheel on the handle 4.

[0020] Specifically, the bottom of the yarn guide 32 is provided with a plastic track 322 for slidingly connecting the upper edge of the yarn mesh 1. The bottom of the plastic track 322 is provided with an opening for the yarn mesh 1 to pass through.

[0021] Specifically, at least two elastic traction components 33 are provided and arranged along the length of the outer profile 31 to ensure the balance of the screen 1. The specific number of elastic traction components 33 depends on the length of the screen door or screen window, and preferably three or more are provided.

[0022] Specifically, the elastic traction component 33 includes a screw 331. One end of the screw 331 is disposed inside the yarn-feeding profile 32, and the other end extends upward and is threadedly connected to the bottom of the groove 310. An elastic element 332 passes through the screw 331 and is disposed inside the yarn-feeding profile 32. The elastic element 332 can be an existing spring. The top of the yarn-feeding profile 32 has multiple through holes 320 for the screw 331 to pass through. The bottom of the groove 310 has a mounting groove 311, and a nut 333 threadedly connected to the screw 331 is disposed in the mounting groove 311. The state of the elastic element 332 lifts the yarn-feeding profile 32, that is, the upper edge of the yarn mesh 1 is lifted by the yarn-feeding profile 32, keeping the yarn mesh 1 taut. If the yarn mesh 1 is affected by external force, the upper edge of the yarn mesh 1 will pull down the yarn-feeding profile 32, causing the yarn-feeding profile 32 to move down and compress the elastic element. 332. When the mesh 1 loses the influence of external force, the restoring force of the elastic element 332 automatically lifts the yarn guide 32, thereby straightening the mesh 1 again. In addition, the height of the screw 331 can be adjusted according to the actual installation to achieve an adjustable effect, which can better ensure the straightness of the mesh 1. If the height of the mesh 1 is greater than the actual installation height, the yarn guide 32 can be lifted up to the straight state of the mesh 1 by tightening the screw 331. Conversely, if the cutting height of the mesh 1 is less than the actual installation height, the screw 331 can be turned down.

[0023] 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.
