Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain and home decoration technology, and in particular to an extendable curtain extension track. Background Technology
[0002] Curtain tracks are widely used in various spaces such as homes, offices, and hotels to hang and move curtains, adjusting indoor light, privacy, and aesthetics. With the improvement of living standards, curtain tracks not only meet basic light-blocking and decorative functions but are also gradually developing towards intelligence and automation, enabling more convenient operation and multi-functional use. Modern curtain track designs place greater emphasis on stability, durability, aesthetics, and ease of maintenance to adapt to the needs of different curtain types and support integration with smart homes.
[0003] However, existing equipment often encounters the following problems during use:
[0004] (1) Many families or offices need to use different types of curtains (such as blackout curtains and light-transmitting curtains) at the same time. Traditional single-track designs cannot meet this need, and curtains need to be changed frequently or multiple tracks need to be used.
[0005] (2) Traditional single-track curtains, especially long-distance or heavy curtain tracks, often bend or deform due to excessive load, resulting in unstable curtains. Utility Model Content
[0006] The main purpose of this utility model is to provide an extendable curtain track, which solves at least one of the above-mentioned problems to a certain extent.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] An extendable curtain track includes:
[0009] A first slide rail housing, wherein a first slide rail is provided inside the first slide rail housing;
[0010] The first slide rail extends through the entire length of the first slide rail housing;
[0011] The second slide rail housing is parallel and slidably connected to the first slide rail housing, and the second slide rail housing is provided inside the second slide rail housing.
[0012] The second slide rail is parallel to the first slide rail;
[0013] A sliding cavity structure is located between the first slide rail housing and the second slide rail housing. The sliding cavity structure includes an inward turning ridge and an outward turning ridge. The inward turning ridge is disposed on one side of the first slide rail housing, and there are two inward turning ridges. The outward turning ridge is disposed on one side of the second slide rail housing, and the number of outward turning ridges corresponds to the number of inward turning ridges. The two inward turning ridges and the two symmetrical outward turning ridges are engaged to form a sliding cavity. The outward turning ridges can slide along the sliding cavity of the inward turning ridge.
[0014] Also includes:
[0015] Anti-detachment limiting protrusion: The end of the inward turning ridge is provided with an anti-detachment limiting protrusion, and there is a gap between the end of the anti-detachment limiting protrusion and the side wall of the first slide rail housing.
[0016] The top of the first slide rail housing and the second slide rail housing are provided with a through-hole groove;
[0017] The guide block is provided at the end of the outward turning edge of the second slide rail housing.
[0018] There is a gap between the end of the anti-detachment limiting protrusion and the side wall of the first slide rail housing.
[0019] The sliding surface of the outward turning edge is provided with a nylon wear-resistant layer with a thickness of 0.3-0.8mm.
[0020] The hollowed-out slot is used to install a third track or smart accessories.
[0021] The contact surface between the inward turning edge and the sliding cavity is provided with a shock-absorbing rubber strip to suppress sliding vibration noise.
[0022] The guide block is shaped to match the anti-detachment limiting protrusion.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] (1) Two parallel sliding tracks allow for the simultaneous installation of two types of curtains, which users can freely adjust according to their needs without frequently changing curtain types. For example, light-transmitting curtains can be used during the day and blackout curtains at night, greatly improving the convenience of use.

[0031] 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.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] like Figure 1-3 As shown, this utility model provides an extendable curtain extension track, which includes a first slide rail housing 1, a first slide rail 2, a second slide rail housing 3, a second slide rail 4, a slide cavity structure 5, an inward turning ridge 51, and an outward turning ridge 52.
[0034] The first track housing 1 houses a first track 2, which extends the entire length of the first track housing 1. The second track housing 3 is parallel to and slides alongside the first track housing 1. The second track housing 3 houses a second track 4, which is parallel to the first track 2. This design allows the two curtain tracks to operate independently or simultaneously, enabling the installation of two different types of curtains, such as blackout curtains and sheer curtains. This design provides great flexibility, allowing users to adjust the opening and closing of the curtains according to their needs, such as using sheer curtains during the day and blackout curtains at night, avoiding the hassle of frequently changing curtains.
[0035] In this invention, the sliding cavity structure 5 is located between the first slide rail housing 1 and the second slide rail housing 3. The sliding cavity structure 5 includes an inward turning ridge 51 and an outward turning ridge 52. The inward turning ridge 51 is located on one side of the first slide rail housing 1, and there are two inward turning ridges 51. The outward turning ridges 52 are located on one side of the second slide rail housing 3, and the number of outward turning ridges 52 corresponds to the number of inward turning ridges 51. The two inward turning ridges 51 and the two symmetrically arranged outward turning ridges 52 are engaged to form a sliding cavity. The outward turning ridges 52 can slide along the sliding cavity of the inward turning ridges 51. The sliding surface of the outward turning ridges 52 is provided with a nylon wear-resistant layer with a thickness of 0.3-0.8 mm. The contact surface between the inward turning ridges 51 and the sliding cavity is provided with a shock-absorbing rubber strip to suppress sliding vibration noise.
[0036] In this invention, the sliding cavity structure 5, through the cooperation of the inward and outward turning edges 52, forms a sliding mechanism that reduces friction between the tracks and makes the track sliding smoother. This structural design helps reduce track wear while avoiding jamming or resistance during sliding. Furthermore, the design of the inward and outward turning edges 51 and 52 effectively controls the relative position between the tracks, preventing errors or failures. The sliding surface of the outward turning edge 52 is provided with a nylon wear-resistant layer, reducing friction during sliding and extending service life. The shock-absorbing rubber strip is used to suppress vibration noise generated during sliding, especially when the curtain slides a long distance or under heavy load. This effectively improves the user experience and avoids noise interference with the living or working environment.
[0037] In this invention, the end of the inward turning ridge 51 is provided with an anti-detachment limiting protrusion 6, and there is a gap between the end of the anti-detachment limiting protrusion 6 and the side wall of the first slide rail housing 1; the gap space between the end of the anti-detachment limiting protrusion 6 and the side wall of the first slide rail housing 1 can effectively prevent the slide rail housing from detaching during sliding and maintain the stability of the track. In addition, the gap space can reduce friction and prevent damage to the track caused by friction generated during sliding.
[0038] In this invention, the tops of the first track housing 1 and the second track housing 3 are provided with through-hole grooves 7. These grooves 7 are used to install a third track or smart accessories. Through concealed wiring, the curtain motor and control cables can be integrated into the gap between the two tracks, improving aesthetics. The impact force when the curtains open and close is distributed to the wall through the parallel tracks, avoiding loosening of the installation anchor points due to stress concentration at a single point. The open grooves 7 on the tops of the first track housing 1 and the second track housing 3 for installing a third track or smart accessories support the function of concealed wiring. This design not only improves the aesthetics of the curtain tracks but also facilitates future expansion, such as adding electric curtain systems, smart sensors, or motors. This avoids replacing the entire track system, improving the system's scalability and future adaptability.
[0039] The second slide rail housing 3 has a guide block 8 at the end of its outward turning ridge 52. The shape of the guide block 8 matches the anti-detachment limiting protrusion 6. The matching design of the guide block 8 and the anti-detachment limiting protrusion 6 helps the track maintain a precise movement path, avoids deviation of the slide rail, and ensures the smooth operation of the system. When the slide rail needs to be disassembled, the combination of the guide block 8 and the limiting protrusion ensures that the slide rail will not fall off accidentally, thereby increasing the safety of the structure.
[0040] It should be noted that the extended curtain track designed in this utility model features two parallel sliding tracks connected side-by-side, allowing for simultaneous or independent operation of two curtains. Two types of curtains, such as sheer curtains + blackout curtains or light-transmitting curtains + soundproof curtains, can be installed simultaneously. Independent sliding is achieved through the parallel tracks, allowing users to use them individually or in combination as needed. For example, during the day, only the sheer curtain can be drawn for light, while the blackout curtain can be closed at night, eliminating the need for frequent curtain changes. When one track vibrates while sliding within its own section, the parallel tracks form a composite support structure, distributing the lateral load during curtain sliding and reducing track bending deformation, making it particularly suitable for extra-long span tracks. Furthermore, the rigid connection of the two tracks suppresses vibration transmission from the sliding rollers, reducing noise during curtain movement. It also supports the addition of a third track, such as an electric curtain track or smart accessories like sensors and motors, without requiring a complete system replacement. If a single track is damaged or a roller is stuck, one set of slide rail housings can be pushed directly. Taking the second slide rail housing 3 as an example, the two symmetrical outward turning edges 52 on one side of the second slide rail housing 3 slide within the sliding cavity formed by the two inward turning edges 51 on one side of the first slide rail housing 1. After sliding to the end, the second slide rail 4 can be slid out. The whole process does not affect the normal use of the other track.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
