Description

Technical Field

[0001] This utility model relates to the field of hanging structure technology, specifically to an adjustable hanging structure for double-layer curtain fabric. Background Technology

[0002] Traditional double-layered curtains typically consist of a blackout fabric layer and a sheer fabric layer to meet different needs for light and privacy. The common method for hanging these curtains is to use two separate hook and track systems to hang the two layers of fabric. This method results in a complex installation structure, higher cost, and a visually bulky appearance.

[0003] In addition, in order to adjust the height difference between the two layers of curtain fabric to meet different aesthetic or functional requirements, some existing adjustable hooks are mostly single-point adjustments, which cannot achieve independent and precise positioning of the two layers of curtains; some structures have problems such as unstable positioning and easy loosening and slippage after adjustment.

[0004] Meanwhile, the hooks used to secure curtains often lack effective anti-slip designs, making it easy for the curtains to accidentally fall off the hooks when pulled, causing inconvenience.

[0005] Therefore, the market urgently needs an integrated hanging structure that is compact, allows for independent and precise adjustment of the height of double-layer curtains, and ensures secure and reliable hanging. Summary of the Invention

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] In the description of this application, the terms "first," "second," etc., 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.

[0017] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs an adjustable double-layer curtain hanging structure, including a main hook body with a vertical support rod 1; a first-layer curtain hanging part 2, which is composed of an arc-shaped connecting part 21 extending to the left from the bottom of the support rod 1, and a limiting rod 22 extending upward and inward from the end of the arc-shaped connecting part 21. The arc-shaped connecting part 21, the limiting rod 22 and the support rod 1 form an upward-facing first hanging opening 23, which is designed as an integral structure, creating a fixed, adjustment-free first-layer curtain hanging point. The upward-facing first hanging opening 23, together with the inward-sloping limiting rod 22, forms a natural anti-slip structure, making it difficult for the curtain to fall off due to external force after it is hung.

[0018] The sliding guide rail 3 is located on the front and rear sides of the support rod 1 and extends vertically. The sliding guide rail 3 is provided with two rows of wedge-shaped one-way locking teeth 31, and the inclination directions of the upper and lower rows of one-way locking teeth 31 are opposite. This provides independent adjustment paths for the upper and lower hanging parts without interference and with opposite movement directions. This structure ensures that after the upper hanging part is adjusted and locked downwards, it self-locks when subjected to an upward force only; after the lower hanging part is adjusted and locked upwards, it self-locks when subjected to a downward force only. The force direction of both under the weight of the curtain is exactly matched with their locking direction, thereby achieving extremely high positioning stability and reliability after adjustment and completely preventing slippage.

[0019] The track connecting hanger 4 has an upper hook 41 at its upper end for connecting the curtain track slider. The opening of the upper hook 41 faces downward, and a first sliding adapter 42 is provided at its lower end. The first sliding adapter 42 is slidably engaged with the sliding guide rail part 3 and is connected to a first one-way locking block 43 that engages with the one-way locking teeth 31 in the upper row. The second layer of curtain hanging part 5 has a lower hook 51 for hanging curtain fabric at its lower end. The opening of the lower hook 51 faces upward and the upper end is provided with a second sliding adapter 52. The second sliding adapter 52 is slidably engaged with the sliding guide rail part 3 and is connected to a second one-way locking block 53 that engages with the lower row of one-way locking teeth 31.

[0020] By clearly separating the functions into two independent sliding components, pure two-degree-of-freedom adjustment is achieved. The track connecting hanger 4 is responsible for connecting with the external track slider and bearing the main weight. The second-layer curtain hanging part 5 is dedicated to hanging the second layer of curtains and can be easily matched with various curtain hooks. Creatively, a static hanging part for fixing the first layer of curtains and two independently sliding dynamic hanging units driven by the sliding guide part are integrated on a single main hook body. This structure allows the blackout curtain and the light-transmitting curtain to share the same hanging base point, resulting in a compact structure and convenient installation.

[0021] In this embodiment, it is further preferred that the first sliding adapter 42 and the second sliding adapter 52 are both provided with a convex-shaped latch that matches the shape of the limiting slide groove. This design forms a precise sliding pair, ensuring that the sliding adapter can only move vertically along the predetermined track, effectively preventing shaking, twisting or derailment during use. The first one-way locking block 43 and the second one-way locking block 53 are elastic latches located at the latch position. The end of the elastic latch has a locking surface that cooperates with the inclined surface of the wedge-shaped one-way locking tooth 31. The elastic latch utilizes the elastic deformation of the material itself, allowing it to bend when sliding over the wedge-shaped tooth. When subjected to reverse force, the locking surface at its end will fit tightly with the inclined surface of the wedge-shaped one-way locking tooth 31, generating a strong mechanical self-locking effect.

[0022] In this embodiment, it is further preferred that the main hook body, the track connecting hanger 4, and the second layer curtain hanging part 5 are all made of plastic. Plastic (especially engineering plastic) raw materials have low cost and are very suitable for one-piece injection molding process. It can efficiently and in large quantities manufacture precision structures including complex tooth shapes, grooves and elastic latches, resulting in high production efficiency and significant cost benefits.

[0023] In this embodiment, it is further preferred that the top of the limiting rod 22 is provided with a guide rod 26 that extends outward at an angle. The guide rod 26 and the support rod 1 form a guide flare, which forms a guide channel that narrows from the outside to the inside. When the user hangs the first layer of curtains, there is no need to align them precisely. The user only needs to insert the hanging hole or hanging strap on the curtain fabric along this flare, and it will be automatically guided to the correct position of the first hanging opening 23.

[0024] In this embodiment, it is further preferred that the front and rear surfaces of the limiting rod 22 and the arc-shaped connecting part 21 are provided with integrally formed and continuously extending grooves 24, which serve as reinforcing ribs in structure. This effectively increases the bending and torsional rigidity of the limiting rod 22 and the arc-shaped connecting part 21 in the front and rear directions, preventing them from deforming due to accidental external forces or long-term use. At the same time, in the injection molding process, this groove 24 ensures that the wall thickness of this area is consistent with that of the main parts such as the support rod 1, which is conducive to melt filling and uniform cooling. This avoids quality defects such as surface shrinkage marks and depressions that may be caused by uneven wall thickness, thereby improving product yield and appearance quality.

[0025] In this embodiment, it is further preferred that two anti-detachment protrusions 25 are provided on the inner side of the limiting rod 22 opposite to the support rod 1, arranged vertically and alternately. The anti-detachment protrusions 25 are triangular in shape, and their triangular design provides an inclined surface facing the inside of the hanging opening, which facilitates hanging. At the same time, it ensures that there are multiple points of obstruction in the vertical direction, so that the curtain fabric can be stably kept in the hanging opening when subjected to normal pulling or external forces such as wind, which greatly enhances the reliability and safety of use.

[0026] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
