Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and more specifically to a pre-embedded track for electric curtains. Background Technology

[0002] Currently, curtains in modern homes primarily serve the functions of providing sun shading and privacy. Generally, motorized curtains are controlled by electrical signals to open and close. Most current smart home systems control the motors of motorized curtains using external controllers. These controllers are electrically connected to the motorized curtains via cables. Users control the controller to generate start and stop signals, which are then transmitted to the motorized curtains via the cables to enable them to open and close.

[0003] However, the existing technologies mentioned above still have some drawbacks. Some existing pre-embedded electric curtains require first excavating larger transmission grooves at both ends in the ceiling or suspended ceiling panel, and then excavating a smaller track groove in the middle to connect them, leaving an installation cavity for the curtain track and transmission box. The track groove needs to be located at the axial center line of the transmission groove, requiring high processing precision. The processing of the track groove may leave edge burrs, which can easily cause the curtain track to bulge during installation. Cleaning the burrs may also create installation gaps during installation, affecting the aesthetics. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a pre-embedded track for electric curtains.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an installation box with an installation cavity installed in a wall, and a track body disposed within the installation box. The installation box includes a central track box, a transmission box, and a cover plate connected to the transmission box. The transmission boxes are symmetrically installed at both ends of the installation box. The cover plate covers the transmission box and its surroundings. The bottom side of the track body extends outwards with a covering flange wider than the central track box. The cover plate has a recessed cavity adapted to the covering flange, which overlaps with the covering flange.

[0006] The present invention is further configured such that: the inner side of the transmission box is provided with a plurality of toothed protrusions formed by longitudinally arranged toothed protrusions; the end face of the box cover extends with an installation protrusion adapted to the box body; and the top of the installation protrusion is provided with a buckle adapted to the toothed protrusion.

[0007] The present invention is further provided with a drive opening on the bottom surface of the box cover that is adapted to an external motor.

[0008] The present invention is further configured such that: the top surface of the transmission box is provided with several screw holes, and is fixed in the mounting cavity by screws; the track body is installed in the mounting cavity together with the middle track box by screws.

[0009] The present invention is further configured such that: the transmission box has a plug-in portion extending from its side end, and the middle track box is provided with a connecting groove that matches the plug-in portion.

[0010] The present invention is further configured such that the thickness of the covering flange is the same as that of the box cover plate.

[0011] In summary, this utility model has the following beneficial effects: the gap between the mounting box and the mounting cavity can be covered by the box cover and the covering flange, allowing the machining accuracy of the mounting cavity to be appropriately reduced, and the mounting cavity can obtain more space for repair and adjustment during installation, making the installation of the track body more aesthetically pleasing and preventing deviation.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This embodiment discloses a pre-embedded track for electric curtains, such as... Figures 1 to 4As shown, the installation includes a mounting box 2 with a mounting cavity 1 installed on the wall 8, and a track body 6 located within the mounting box 2. The mounting box 2 includes a central track box 3, a transmission box 4, and a cover plate 5 connected to the transmission box 4. The transmission box 4 is symmetrically installed at both ends of the mounting box 2. The cover plate 5 covers the transmission box 4 and its surroundings. The outer edge of the cover plate 5 is larger than the cross-sectional dimension of the transmission box 4. When installed, the outer edge of the cover plate 5 can cover some gaps in the transmission box 4 and its surroundings, allowing for a larger tolerance range in the machining of the transmission groove 11, enabling greater repair work and reducing the machining requirements of the mounting cavity 1. Simultaneously, the transmission groove 11... The track body 6 can be fitted to the track groove 12 to avoid displacement of the track groove 12; the bottom side of the track body 6 extends outward with a covering flange 61 that is wider than the middle track box 3. The covering flange 61 can cover the gap between the track groove 12 and the middle track box 3, so that there is a certain tolerance space between the track groove 12 and the track box; when the track groove 12 is large, the residual burrs will be in the gap and will not affect the installation of the track. When the track groove 12 is small, the gap generated during cleaning will be covered by the covering flange 61; the box cover plate 5 is provided with a cavity adapted to the covering flange 61, and the cavity and the covering flange 61 form an overlapping fit.

[0019] Further improvements include a plurality of toothed protrusion groups 42 formed by longitudinally arranged toothed protrusions on the inner side of the transmission box 4. The end face of the box cover 5 extends to accommodate mounting protrusions 52 adapted to the box body. The top of each mounting protrusion 52 is provided with a toothed protrusion-compatible buckle 521. The mounting protrusions 52 have a certain degree of elasticity, and installation requires no special tools; simply pushing the box cover 5 into the transmission box 4 body easily connects the box cover 5 and the transmission box 4 body. The longitudinal arrangement of the mounting protrusions 52 and the toothed protrusion groups 42 on the inner side of the box forms a spatial matching relationship, achieving rapid positioning through the meshing of the protrusions and the tooth grooves, ensuring alignment of the box cover and the central axis of the box body.

[0020] To further improve the design, the bottom surface of the cover plate 5 is provided with a drive opening 51 adapted to an external motor. The opening allows the external drive motor to enter, connect to, and drive the control motor, making maintenance and replacement of the drive motor simple and convenient to complete by simply reaching through the opening.

[0021] Further improvements include several screw holes on the top surface of the transmission box 4, which is fixed to the mounting cavity 1 by screws 7; the track body 6 is also installed in the mounting cavity 1 together with the central track box 3 by screws 7. The use of screws 7 ensures a secure connection between the transmission box 4 and the track body 6 within the mounting cavity 1, preventing displacement or loosening due to vibration during equipment operation. The application of high-strength screws 7 effectively withstands dynamic loads, ensuring long-term operational stability.

[0022] Further improvements include a plug-in portion 41 extending from the side of the transmission box 4, and a connecting groove 31 adapted to the plug-in portion 41 in the central track box 3. The plug-in portion 41 and the connecting groove do not require complex tools; connection can be completed simply by plugging them in, significantly shortening installation time. Furthermore, it avoids incorrect orientation or misalignment during installation, reducing installation errors.

[0023] To further improve the design, the thickness of the covering flange 61 is the same as that of the box cover plate 5. Both the covering flange 61 and the box cover plate 5 are 1mm thick. After installation, a 1mm thick layer of putty will be used to smooth the ceiling, making the surface thickness more uniform, reducing the risk of cracking, and resulting in a smoother and more aesthetically pleasing finish.

[0024] Working principle of this utility model

[0025] During the carpentry stage of decoration, the track groove 12 and transmission groove 11 are placed according to the size of the mounting box 2 at the location where this utility model needs to be installed, and are adjusted according to the size of the mounting box 2 so that the mounting box 2 can be installed accurately and properly.

[0026] During installation, the transmission box 4 can be easily installed by inserting it into both sides of the central track box 3. The installed installation box 2 is then placed in the track slot, and the transmission box 4 with screw holes is fixed to the track slot using screws 7.

[0027] During the painting stage, the starting motor and the assembled track body 6 will be combined, and the combined body will be installed in the mounting box 2 by screws 7. The box cover plate 5 will be covered, and when applying putty, the edge of the box cover plate 5 and the covering flange 61 will be smoothed with a thickness of about 1mm to achieve the pre-embedded effect.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
