Description

Technical Field

[0001] The utility model relates to the technical field of curtain accessories, in particular to a curtain rail. Background Art

[0002] A curtain rail is a concealed or decorative rail used to hang curtains in interior decoration, which is divided into two types: visible rail and hidden rail. A visible rail, that is, a Roman rod or a decorative rail, is usually made of aluminum alloy, solid wood or steel pipe, is easy to install, has a certain decorative effect, and is suitable for modern home decoration. A hidden rail is hidden in a curtain box, preferably made of aluminum alloy, has smooth sliding and strong load-bearing capacity, and is suitable for hanging multiple layers of curtains. The installation methods of curtain rails are diverse, including top installation, side installation, etc., and need to be selected according to the window position and the interior style. High-quality rails should have good pulley load-bearing capacity, safe materials and brand reputation to ensure smooth opening and closing of the curtains and durability. Regular cleaning and maintenance, avoiding the use of chemical detergents, can extend the service life of the rail and improve the living comfort.

[0003] Taking the visible rail as an example, currently, curtain rails often use profiles as rails, with hanging rings slidingly connected to the rails, and then the curtains are installed. Due to different window frame specifications, there are certain requirements in the current market for curtain rails to have sizes that can match different window frames.

[0004] Therefore, in the prior art, profiles are used as rails to support the hanging rings. In the prior art, whether they are made of alloy materials, plastic materials, or even plastic-steel materials, they all have their own problems. If it is an alloy material rail, if it is necessary to ensure the structural strength, then it is necessary to provide profiles with a special-shaped cross-section. However, in this way, the profiles need to be processed by extrusion, which will also cause a significant increase in the cost of the rail. And plastic material rails are also processed by hot melt extrusion, but their structural strength will be weakened after the rail is lengthened. Therefore, plastic-steel material rails are selected for use, but the result is that their production efficiency is significantly reduced, and indirectly their cost increases. Therefore, it is necessary to use a metal material as the material of the rail and use a simpler structure that can ensure the structural strength as the structure of the rail.

[0005] Therefore, a curtain rail is proposed to solve or alleviate the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies in the prior art and propose a curtain rail.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A curtain rail includes a connecting insertion rail, connecting rails sleeved on the outer sides of both ends of the connecting insertion rail, an extension rail embedded in and slidably disposed at one end of the connecting rail away from the connecting insertion rail, an end rail connected to one end of the extension rail away from the connecting rail and used for closing, and a sliding ring slidably connected in the connecting rail and the extension rail. The connecting insertion rail includes a first bottom plate and two first rail bars integrally formed with the first bottom plate and in an L shape. There is a chute between the two first rail bars for the sliding ring to slide. The width of the first bottom plate is greater than the maximum distance between the two first rail bars. The cross-sections of the connecting insertion rail, the connecting rail, and the extension rail are similar figures.

[0009] Preferably, the connecting rail includes a strip-shaped second bottom plate and two L-shaped first rail sleeves. The two sides of the second bottom plate are folded inward to form first folding parts. The first rail sleeves are integrally formed with the first folding parts. The first bottom plate can be embedded between the second bottom plate and the first folding parts. The first rail sleeves can be arranged to fit the inner sides of the first rail bars.

[0010] Preferably, a reinforcing insertion rail is integrally formed at one end of the connecting rail away from the connecting insertion rail. The opening cross-section of the reinforcing insertion rail is the same as that of the connecting rail. The thickness of the reinforcing insertion rail is greater than that of the connecting rail.

[0011] Preferably, the extension rail includes a third bottom plate and two L-shaped second rail bars. The two sides of the third bottom plate are folded inward to form second folding parts. The second rail bars are integrally formed with the second folding parts. The second rail bars are arranged to fit the inner sides of the connecting rail and the reinforcing insertion rail.

[0012] Preferably, the end rail includes a fourth bottom plate that can be embedded between the third bottom plate and the second folding parts, and two L-shaped third rail bars integrally formed on the fourth bottom plate. A limiting bottom plate is integrally formed at one end of the fourth bottom plate away from the third bottom plate. A limiting rail sleeve is integrally formed at one end of the third rail bar away from the second rail bar. The width, thickness, or both of the limiting bottom plate are greater than the width, thickness, or both of the fourth bottom plate. The inner opening cross-section of the limiting rail sleeve is the same as the inner opening cross-sections of the two third rail bars. The thickness of the limiting rail sleeve is greater than that of the third rail bar. One end of the limiting rail sleeve is open and the other end is closed.

[0013] Preferably, the end rail further includes two connecting pieces, a connecting block fixedly connected between the connecting pieces and located inside the limiting rail sleeve, and a fixed ring plate fixedly connected to the top surface of the upper connecting piece. A first through hole is formed in the fixed ring plate. One of the connecting pieces is arranged to fit the top surfaces of the third rail bar and the limiting rail sleeve. The other connecting piece is arranged to fit the top surfaces of the fourth bottom plate and the limiting bottom surface.

[0014] Preferably, a first through hole is formed in the connecting piece, a second through hole coaxially communicating with the first through hole is formed in the fourth bottom plate, a threaded hole capable of coaxially communicating with the second through hole is formed in the third bottom plate, and a fastening member passing through the first through hole and the second through hole is threadedly connected in the threaded hole.

[0015] Preferably, the slip ring includes a movable ring piece that can extend out of the chute, a bottom sliding piece and a top sliding piece integrally formed on the movable ring piece. The distance between the bottom sliding piece and the top sliding piece is greater than the distance between the second bottom plate and the top surface of the reinforcement insertion rail. A second through hole is formed in the movable ring piece above the top sliding piece.

[0016] The utility model has the following beneficial effects:

[0017] In the curtain rail of the utility model, the connection of the insertion rail greatly enhances the connection strength of the two side connection rails. The design of the first rail perpendicular to the first bottom plate not only effectively prevents the deformation of the bottom plate in the width direction, but also enhances the thickness of the bottom plate through the variable addition of thickness treatment, thereby improving the structural strength of the connection insertion rail in the length direction. The addition of the reinforcement insertion rail provides additional thickness and structural strength for the end of the connection rail far from the connection insertion rail, effectively preventing bending and collapse;

[0018] When it is necessary to adjust the length of the curtain rail according to the width of the window frame, it can be easily adjusted by sliding the extension rail, so that the rail can adapt to window frames of different widths. If the width of the window frame exceeds the maximum length of the rail, the user can add a new connection insertion rail and connection rail at one end of the connection rail and install the extension rail in the conventional way to realize the extension of the rail. This design ensures that even during splicing, a strong connection strength can be maintained and separation can be avoided;

[0019] In addition, the curtain rail structure of the utility model is simple and easy to be processed by means of die pressing, greatly reducing the production difficulty and cost. Whether it is the connection insertion rail, the connection rail or the extension rail, they can all be processed from conventional U-shaped profiles, making the production process more efficient.

The second rail bars 402 are integrally formed with the second folding parts and are arranged in a fitting manner on the inner sides of the connecting rail 2 and the reinforcing insertion rail 3.

[0037] The end rail 5 includes a fourth base film 501 that can be embedded between the third base film 401 and the second folding parts, two L-shaped third rail bars 502 integrally formed on the fourth base film 501, two connecting pieces 505, a connecting block fixedly connected between the connecting pieces 505 and located within the limit rail sleeve 504, and a fixed ring piece 506 fixedly connected to the top surface of the upper connecting piece 505. One end of the fourth base film 501 away from the third base film 401 is integrally formed with a limit base film 503. One end of the third rail bar 502 away from the second rail bar 402 is integrally formed with a limit rail sleeve 504. The width, thickness, or both of the limit base film 503 are greater than the width, thickness, or both of the fourth base film 501. The inner opening cross-section of the limit rail sleeve 504 is the same as the inner opening cross-sections of the two third rail bars 502. The thickness of the limit rail sleeve 504 is greater than the thickness of the third rail bar 502. One end of the limit rail sleeve 504 is open and the other end is closed. The fixed ring piece 506 is provided with a first through hole 507. One of the connecting pieces 505 is arranged in a fitting manner on the top surfaces of the third rail bar 502 and the limit rail sleeve 504, and the other connecting piece 505 is arranged in a fitting manner on the top surfaces of the fourth base film 501 and the limit bottom surface.

A second through hole 604 is provided on the movable ring piece 601 above the top sliding piece 603.

[0039] In the actual application of the present utility model, due to the provision of the connecting insertion rail 1, when connecting the two connecting rails 2 on both sides, the structural strength of the connection part between the two can be strengthened. And due to the provision of the first bottom plate 101 in the connecting insertion rail 1, it is not easy for the connecting insertion rail 1 to break away from the connecting rail 2. In addition, since the first bottom plate 101 is strip-shaped, it is not easy to deform in the width direction. The first rail is perpendicular to the first bottom plate 101, which relatively thickens the thickness of the first bottom plate 101, so as to ensure that the first rail can strengthen the structural strength of the connecting insertion rail 1 in the length direction. The provision of the reinforcing insertion rail 3 thickens the thickness of the end of the connecting rail 2 away from the connecting insertion rail 1, thereby increasing the structural strength at the junction of the connecting rail 2 and the extended rail 4, so that the connection between the two is not easy to bend and collapse. Both the connecting insertion rail 1, the connecting rail 2, and the extended rail 4 can be processed and formed from conventional U-shaped profiles by molding, which can greatly reduce the production difficulty of this curtain rail;

[0040] When the curtain rail in the present utility model needs to be used, if the width of the window frame is between the maximum length and the minimum length of this curtain rail, then at this time, the available length can be adjusted by sliding the extended rail 4, and then the length of the entire curtain rail can be adjusted so that the entire curtain rail can adapt to the width of the window frame. However, if the width of the window frame is greater than the maximum length that this curtain rail can reach, at this time, a new connecting insertion rail 1 can be inserted at the end of the connecting rail 2 away from the connecting insertion rail 1, and then a new connecting rail 2 can be added at the end of the new connecting insertion rail 1 away from the connecting rail 2, and then structures such as the extended rail 4 can be installed according to the normal connection method, and then the lengthening operation of the entire curtain rail can be completed. And even if the structures in this curtain rail do not involve the structures of relatively complex special-shaped profiles, they can still maintain strong connection strength during splicing and are not easy to separate. In addition, due to the simple structure of this curtain rail, it can be obtained by processing ordinary U-shaped profiles by molding, with easy processing and low cost.

[0041] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
