Description

Technical Field

[0001] This utility model relates to the technical field of screen windows, and in particular to a sliding track structure for a roller blind screen window. Background Technology

[0002] The main function of window screens is to prevent insects and other animals from entering. Traditional window screens are simply a layer of mesh fixed to the window, also known as fixed screens. Referring to the public announcement number CN221299034U, a labor-saving invisible window screen, also called a roll-up screen or roller blind screen, has an automatic roll-up function. When needed, the mesh is pulled down; when not in use, it automatically rolls back into the mesh box, saving space. It mainly includes an outer frame, a roller structure, and a pull rod. The roller structure is located within one side profile of the outer frame and is connected to the mesh. The other side of the mesh is connected to the pull rod. The upper and lower profiles of the outer frame serve as sliding rails, with the center line of the rails corresponding to the center of the roller structure. This allows the pulling rod and the screen to slide. The screen is pulled out to the other side profile by the pulling rod. However, the roller structure has a certain thickness, and the screen wrapped around it is not aligned with the center line of the sliding rail. Referring to the figure, when the pulling rod pulls the screen out, the screen needs to be folded into the sliding rail at a certain angle. That is, the part of the screen on the sliding rail and the part before entering the sliding rail will form an angle, causing the current roller blind screen to have insufficient smoothness and is prone to jamming. If pulled forcefully, it may also damage the screen. Utility Model Content

[0003] The present invention provides a sliding track structure for a roller blind screen, so as to guide the screen into the sliding track groove and make the screen move more smoothly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding track structure for a roller blind screen, comprising a screen, two side profiles, and track profiles. A roller structure is provided within one of the side profiles, and the screen is wound around the outer curved surface of the roller structure. Both track profiles are provided with sliding track grooves, and an access channel is provided at one end of each sliding track groove. The end of the access channel away from the sliding track groove has a trumpet-shaped opening, which gradually narrows from the roller structure towards the sliding track groove. A finishing edge is provided at the top of the access channel, and a sealing edge that slides within the sliding track groove is provided on the outer edge of the screen. The thickness of the sealing edge corresponds to the width of the finishing edge.

[0005] Furthermore, the groove opening of the slide rail is bent inward and narrowed, and the width of the groove opening corresponds to the width of the edge.

[0006] Furthermore, the slide rail groove wall is provided with positioning strips, and the mesh slides between the two positioning strips.

[0007] Furthermore, the inner side of the opening is provided with an arc surface.

[0008] Furthermore, the end of the track profile is provided with an end cap, and the access channel is provided on the end cap.

[0009] Furthermore, the track profile has an inner cavity, and the end cap is provided with a protruding ridge that matches the inner cavity.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the set access channel, one end of the access channel has an opening, the mesh enters the slide rail groove through the access channel, and the opening guides the mesh to enter smoothly, making the mesh move more smoothly and preventing jamming.

[0018] 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.

[0019] As shown in the attached figure, the present invention discloses a sliding track structure for a roller blind screen, comprising a screen 1, two side profiles 2, and track profiles 3. A roller structure 21 is provided within one of the side profiles 2, the roller structure 21 including a pivot and two bases, the two bases being respectively disposed at both ends of the side profile 2. The screen 1 is wound around the outer curved surface of the roller structure 21. Both track profiles 3 are provided with sliding track grooves 30, one end of each sliding track groove 30 being provided with an access channel 40. The end of the access channel 40 away from the sliding track groove 30 is provided with a trumpet-shaped opening 41, the opening 41 gradually narrowing from the roller structure 21 to the sliding track groove 30. The top of the access channel 40 is provided with a finishing edge 42. The outer edge of the screen 1 is provided with a sealing edge 11 that slides on the sliding track groove 30, the thickness of the sealing edge 11 corresponding to the width of the finishing edge 42.

[0020] This utility model discloses a sliding track structure for a roller blind screen. Through the set access channel 40, one end of the access channel 40 has an opening 41. The screen 1 enters the sliding track groove 30 through the access channel 40. During the process, the screen 1 passes through the opening 41. As the opening 41 gradually narrows, the screen 1 is introduced into the access channel 40. The opening 41 guides the screen 1 to enter smoothly, making the screen 1 move more smoothly and preventing jamming.

[0021] In this embodiment, the groove of the slide rail 30 is bent inward and contracted. The width of the groove of the slide rail 30 corresponds to the width of the edge closing opening 42. Preferably, the width of the groove is equal to the width of the edge closing opening 42, making it difficult for the sealing edge 11 to detach from the slide rail 30 and the access channel 40.

[0022] In this embodiment, the slide rail groove 30 is provided with positioning strips 32 on the groove wall. The mesh 1 slides between the two positioning strips 32. The positioning strips 32 are made of flexible material, which can prevent the mesh 1 from contacting the metal profile of the slide rail groove 30, and can also hold the edge 11 of the mesh 1 to prevent the mesh 1 from falling off the slide rail groove 30.

[0023] As shown in the figure, the inner side of the opening 41 is provided with an outwardly convex arc surface 411, so that the mesh 1 can smoothly enter the access channel 40 along the arc surface 411.

[0024] The end of the track profile 3 is provided with an end cap 4, and the access channel 40 is provided on the end cap 4. The end cap 4 is integrally injection molded. The track profile 3 has an inner cavity 33. The end cap 4 is provided with a protruding rib 44 that matches the inner cavity 33. The end cap 4 is mainly used to seal the end face of the track profile 3 to prevent the end face from being exposed. At the same time, the access channel 40 is reserved. The end cap 4 can also seal the two ends of the side profile 2 on which the roller structure 21 is installed.

[0025] 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.
