Description

Technical Field

[0001] This utility model relates to the field of curtain track technology, and more specifically, to a concealed curtain track structure. Background Technology

[0002] Ceiling-mounted curtain systems are widely used in modern interior design due to their simple and aesthetically pleasing features. The system typically consists of a track profile fixed to the ceiling, a guide rail installed within the track profile, and accessories such as pulleys.

[0003] Currently, a modular design is commonly used to facilitate the production and assembly of long track profiles. However, this design has significant drawbacks during on-site installation: installers must rely on additional independent connecting brackets, bolts, and other fasteners for assembly. This not only increases component costs and complicates installation procedures but also easily creates noticeable assembly gaps at the joints between profile sections. These gaps lead to unavoidable light leakage, severely impacting the overall light-blocking performance of the curtains and failing to meet users' needs for a completely blackout environment. Furthermore, improper handling of the strength and straightness of the joints can directly affect the smoothness of the sliding and the stability of the system. Utility Model Content

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] See Figures 1-9This utility model embodiment provides a concealed curtain split track structure, including track profiles. The track profiles include a first profile frame 1, a second profile frame 2, and a third profile frame 3. The first profile frame 1 and the third profile frame 3 are respectively connected to both ends of the second profile frame 2. The second profile frame 2 has a first insertion end 201 at the end near the first profile frame 1, and the first profile frame 1 has a first insertion slot 101 corresponding to the first insertion end 201. The second profile frame 2 has a second insertion end 202 at the end near the third profile frame 3, and the third profile frame 3 has a second insertion slot 301 corresponding to the second insertion end 202. A first insertion block 41 is provided on the inner wall of a first insertion slot 101, a second insertion block 42 is provided on the inner wall of a second insertion slot 301, and a third insertion slot 203 is provided on a second profile frame 2. The third insertion slot 203 extends along the extension direction of the second profile frame 2, and the first insertion block 41 and the second insertion block 42 are respectively inserted into the two ends of the third insertion slot 203. This utility model has a simple structure and low production cost. It is assembled through the structure of the first profile frame, the second profile frame and the third profile frame itself, without the need for additional parts. It is convenient to assemble, easy to disassemble, and low in cost. The installer does not need complicated processes. The installation is efficient and safe. The structure is stable after assembly and is not prone to light leakage.

[0029] Specifically, in this embodiment, the rapid initial positioning and assembly of the three profile frames can be achieved by inserting the first insertion end 201 and the second insertion end 202 into the corresponding insertion slots; then, the first insertion block 41 and the second insertion block 42 are interlocked with the third insertion slot 202 through secondary sliding insertion to form a solid whole. The assembly is convenient and quick, saves costs, and improves the strength and straightness of the connection. Due to the insertion of the first insertion end 201 and the second insertion end 202 into the corresponding insertion slots, most of the splicing gap between the first insertion end 201 and the first profile frame 1 is blocked by the inner wall of the first insertion slot 101, reducing light leakage; at the same time, most of the splicing gap between the second insertion end 202 and the third profile frame 3 is blocked by the inner wall of the second insertion slot 301, reducing light leakage; in this embodiment, both the first profile frame 1 and the third profile frame 3 are made of plastic.

[0030] See Figures 3-6The third insertion slot 203 has a first slot 2031 at one end near the first profile frame 1 and a second slot 2032 at the other end near the third profile frame 3. During installation, the first insertion end 201 is inserted into the first insertion slot 101 along the extension direction of the second profile frame 2, and the second insertion end 202 is inserted into the second insertion slot 301 along the extension direction of the second profile frame 2. The first insertion block 41 is inserted into one end of the third insertion slot 203 from the first slot 2031, and the second insertion block 42 is inserted into the other end of the third insertion slot 203 from the second slot 2032. By inserting the first insertion block 41 and the second insertion block 42 into the first slot 2031 and the second slot 2032 respectively, the precise alignment and smooth insertion of the two insertion blocks into the third insertion slot 203 are achieved. Meanwhile, the slot structure restricts the insertion block to slide within the slot, forming a tight longitudinal interlock, which improves the connection rigidity and integrity between the three profile sections; the first insertion block 41, the second insertion block 42 and the third insertion slot 203 are all symmetrically arranged in twos; the symmetrical layout makes the connection force evenly distributed, avoids torque generated by force on one side, and improves the stability of the structure.

[0031] See Figure 4 and Figure 5 The second profile frame 2 has a protruding strip 21 along its extension direction. A third insertion groove 203 is formed between the protruding strip 21 and the second profile frame 2. One end of the protruding strip 21 is inserted into the first insertion groove 101, and the other end of the protruding strip 21 is inserted into the second insertion groove 301. The protruding strip 21 acts as a continuous reinforcing rib, improving the bending stiffness and integrity of the track at the joint and preventing sagging or deformation. The two ends of the protruding strip 21 are respectively inserted into the first insertion groove 101 and the second insertion groove 301, which improves the structural stability after splicing. At the same time, the third insertion groove 203 is formed between the protruding strip 21 and the second profile frame 2, so that the third insertion groove 203 can be inserted and positioned with the corresponding insertion block. The structure is ingeniously designed and the structure is more stable after splicing.

[0032] See Figures 4-9 The first plug-in block 41 and the second plug-in block 42 are both T-shaped. The protrusion 21 includes the first protrusion 211 and the second protrusion 212. The third plug-in groove 203 is a T-shaped groove, which is formed between the first protrusion 211, the second protrusion 212 and the second profile frame 2. The T-shaped structure realizes two-way mechanical interlocking in the horizontal and vertical directions, effectively resists pull-out force and torque in all directions, and enhances the reliability and stability of the connection.

[0033] See Figure 7 and Figure 8The first plug-in block 41 is provided with a first guide slope 411 at one end to facilitate insertion into one end of the third plug-in slot 203, and the second plug-in block 42 is provided with a second guide slope 421 at one end to facilitate insertion into the other end of the third plug-in slot 203. The guide slope can guide the plug-in block and the third plug-in slot 203 at the moment of contact, making the plug-in process smoother, reducing assembly difficulty and improving assembly efficiency.

[0034] See Figure 1 The upper side of the track profile is used to connect to the external ceiling 9. The first profile frame 1 is connected to the ceiling 9 with a first bolt. The first profile frame 1 is provided with several first bolt holes 102 for installing the first bolt. The third profile frame 3 is connected to the ceiling 9 with a second bolt. The third profile frame 3 is provided with several second bolt holes 302 for installing the second bolt. It is fixed by bolts, which is simple in structure, easy to install and easy to disassemble.

[0035] See Figure 1 and Figure 9 The track profile has an inner mounting groove 10, within which a guide rail frame 7 is fixedly mounted with bolts. Side plates 5 are located on both sides of the track profile. The upper side of the side plates 5 connects to the ceiling 9, and the lower side of the side plates 5 connects to a plate 6. The plate 6 has a lower side surface 601, and the guide rail frame 7 has a lower end 701, which is vertically higher than or flush with the lower side surface 601. The guide rail frame 7 is concealed within the ceiling 9 and the plate 6, preventing its lower part from being exposed and enhancing the interior aesthetics. The concealed guide rail frame offers excellent aesthetics and spatial integrity, preventing dust accumulation and facilitating cleaning and maintenance. It also reduces the risk of collisions and damage from external objects, extending its lifespan. The guide rail frame 7 is used to install curtain accessories such as rollers; the installation of rollers and other curtain accessories on the guide rail frame 7 is existing technology and will not be elaborated upon here. Specifically, the second height M is the vertical height between the center line of the side panel 5's thickness and the bottom of the track profile. In this embodiment, the ceiling is made of wood, steel, or a keel frame, etc.; the panel 6 is made of gypsum board, wood, or composite board, etc.

[0036] See Figure 1 and Figure 9The side panel 5 includes a first side panel 51 mounted on the first profile frame 1, a second side panel 52 mounted on the second profile frame 2, and a third side panel 53 mounted on the third profile frame 3. The first side panel 51, the second side panel 52, and the third side panel 53 are at the same horizontal height. The first side panel 51 and the third side panel 53 respectively abut against the two ends of the second side panel 52. The three side panels are spliced ​​together to form a complete and continuous side panel for subsequent installation of the horizontally extended panel 6. The extension length of the second profile frame 2 can be selected according to the curtain product, and it has good versatility. (The lengths of the second profile frame 2, guide rail frame 7, and other parts in the attached drawings of this embodiment are for illustrative purposes only. The actual lengths need to be determined according to the curtain product.) (Depending on the length of the product); the height of the track profile is the first height L, and the vertical height between the side plate 5 and the bottom of the track profile is the second height M. The ratio of the second height M to the first height L is 0.4-0.6. This ratio design allows the track profile to adapt to most standard ceiling thicknesses, improving the product's versatility and applicability. If the ratio of the second height M to the first height L is too small, a thicker ceiling 9 is required for installation, and it is not suitable for ceilings with smaller thicknesses. If the ratio of the second height M to the first height L is too large, a thicker plate 6 is required, increasing the cost of using the plate 6. In this embodiment, the ratio of the second height M to the first height L is 0.5 or close to 0.5.

[0037] The concealed curtain split track structure of this utility model is simple in structure and low in production cost. Assembly is achieved through the structure of the first, second, and third profile frames themselves, requiring no additional parts. Assembly is convenient, disassembly is easy, and cost-effective. Installation requires no complex techniques, is efficient and safe, and the assembled structure is stable. The first and second insertion ends 201 and 202 are connected to their corresponding insertion slots, enabling rapid initial positioning and assembly between the three profile frames. Furthermore, the first and second insertion blocks 41 and 42 are connected to the third... The three-pronged insertion slot 202 interlocks with secondary sliding insertion, forming a solid whole. This makes assembly convenient and quick, saves costs, and improves the strength and straightness of the connection. Because the first insertion end 201 and the second insertion end 202 are inserted into the corresponding insertion slots, most of the splicing gap between the first insertion end 201 and the first profile frame 1 is blocked by the inner wall of the first insertion slot 101, reducing light leakage. At the same time, most of the splicing gap between the second insertion end 202 and the third profile frame 3 is blocked by the inner wall of the second insertion slot 301, making it less likely for light to leak.
