[0054] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0055] like Figures 1 to 3 As shown, a telescopic clothes-drying rod assembly 100 driven by an electric chain mechanism comprises a fixed clothes-drying rod assembly 101, a movable clothes-drying rod assembly 102, and an electric chain mechanism 30. These three components allow for independent operation while working in concert to achieve the rod's telescopic function. The fixed clothes-drying rod assembly 101 includes two fixed clothes-drying rods 10 and two rod bases 20. The fixed clothes-drying rods 10 and rod bases 20 form a rectangular frame, providing a stable base and ensuring the assembly's stability and load-bearing capacity during use.

[0056] The movable clothes drying rod assembly 102 is designed to be retractable and can be used in conjunction with the fixed clothes drying rod assembly 101 to adjust the size of the clothes drying space according to the drying needs. This technical means increases the adaptability and convenience of the clothes drying rod.

[0057] The electric chain mechanism 30 serves as a driving force and is responsible for controlling the telescopic movement of the movable clothes drying rod assembly 102. The electric drive reduces the labor intensity of manual operation and provides a more convenient and faster clothes drying experience.

[0058] More specifically, the movable laundry rod assembly 102 includes support rods 11 that can be extended and retracted on the fixed laundry rod 10, and a crossbar 12 located between the two support rods 11. The movable laundry rod assembly 102 includes support rods 11 and crossbar 12. The support rods 11 can be extended and retracted on the fixed laundry rod 10 to adjust the laundry drying space. The crossbar 12, located between the support rods 11, not only serves as a connection but also increases the load-bearing capacity and stability of the laundry rod.

[0059] The rod base 20 includes an inner region 21 and an outer region 22. The lower end of the folding frame 30 extends across the inner region of the rod base 20. The inner region 21 supports the lower end of the folding frame 30, while the outer region 22 is used to mount the housing 31. This partitioned arrangement optimizes space utilization while ensuring structural stability and functionality.

[0060] The housing 31 is mounted on the outer area 22 of the rod base 20. The rod base 20 includes an outer wall 23 with a window 24 through which the chain push rod 32 extends. This protects the internal mechanical components and facilitates the operation of the chain push rod 32. The chain push rod 32 is connected to the outer end of the crossbar 12 and is driven by a motor to achieve its extension and retraction. This allows for smoother and more controllable deployment and retraction of the drying rod assembly.

[0061] The electric chain mechanism 30 includes a housing 31, a motor, and a chain push rod 32. The motor is housed within the housing 31, and the chain push rod 32 is activated by the motor to extend or retract into the housing 31. The internal motor reduces the complexity of external wiring and improves the overall aesthetics and ease of operation of the assembly.

[0062] When the chain push rod 32 retracts into the housing 31, the crossbar 12 driven by the chain push rod 32 drives the support rod 11 to retract into the fixed drying rod 10, and the movable drying rod assembly 102 is now in a retracted state. When the chain push rod 32 extends outward, the crossbar 12 driven by the chain push rod 32 drives the support rod 11 to extend outside the fixed drying rod 10, and the movable drying rod assembly 102 is now in an extended state. Specifically, when the chain push rod 32 retracts into the housing 31, the crossbar 12 and support rod 11 are also retracted, and the movable drying rod assembly 102 reaches a compact storage state. Conversely, when the chain push rod 32 is extended, the crossbar 12 and support rod 11 are extended, providing a larger drying space.

[0063] Preferably, the motor of the electric chain mechanism 30 may be equipped with an intelligent control system, such as a remote control or a smartphone APP control, so that the user can more conveniently operate the unfolding and folding of the clothes drying rod.

[0064] The chain push rod 32 includes a plurality of chains a connected to each other. The chain push rod 32 can be extended or shortened in a straight line, ensuring consistency and stability during the extension and shortening process, and ensuring the synchronization of the extension and contraction of the support rod.

[0065] In addition, the use of chain a is intended to enhance transmission efficiency and force transmission, ensuring that the power generated by the motor can be effectively converted into the telescopic action of the clothes drying rod assembly.

[0066] Preferably, a bamboo-like telescopic sleeve 40 is provided between the rod base 20 and the crossbar 12, with the chain push rod 32 positioned within the bamboo-like telescopic sleeve 40. This bamboo-like design minimizes the space occupied by the telescopic sleeve 40 when retracted. Furthermore, the chain push rod 32 positioned within the bamboo-like telescopic sleeve 40 allows the movement of the chain push rod 32 to be directly transmitted to the telescopic sleeve, driving the extension and retraction of the crossbar 12 and support rod 11, thus simplifying the transmission path.

[0067] The bamboo-jointed telescopic sleeve 40 is composed of a plurality of sleeves p with gradually changing diameters. The cross-sectional design of the sleeve p is diverse and can be circular, oval, rectangular or quasi-rectangular. In order to optimize the flexibility of the structure and adapt to different production needs. The sleeves p are arranged in the direction from the rod seat 20 to the cross bar 12, and the cross-sectional size of each sleeve is reduced proportionally in turn. This decreasing technical means allows the sleeves p to be effectively nested when folded, saving space and improving the overall compactness. In actual work, when the clothesline needs to be folded, the smaller sleeves p are stacked into the adjacent larger sleeves in turn. This stacking mechanism enables all the sleeves to be compactly stored, reducing the occupied space, and the stacking process eventually enables all the sleeves p to be placed in the first sleeve 41, achieving complete storage. The stacking and unfolding process of the sleeves p should be simple and intuitive, and the user can easily operate without complicated steps or tools.

[0068] It should be noted that the cross-sectional dimensions of connector b are smaller than those of window 24, so that connector b can be placed within window 24. The cross-sectional dimensions of connector b are precisely set to be smaller than those of window 24, ensuring that the connector can be smoothly and tightly placed within window 24, forming a stable fit; it also ensures that the fit between connector b and window 24 optimizes space utilization.

[0069] like Figures 6 to 8 As shown, the front end of the chain push rod 32 is provided with a connector b, which is fixedly installed on the inner side of the cross bar 12 to ensure that the movement of the push rod can be directly transmitted to the cross bar, thereby achieving precise control of the telescopic movement of the clothes drying rod.

[0070] The first segment 41 of the bamboo-jointed telescopic sleeve 40 is positioned over window 24. This design makes this first segment the starting point of the telescopic sleeve series, providing a reference and anchor point for the entire telescopic mechanism. The first segment 41 includes two fixing plates c on either side, which are fixed to the window 24. These fixing plates c provide stable support for the first segment 41, ensuring that it remains securely positioned over the window 24 during the clothesline extension and retraction process.

[0071] Preferably, the end section sleeve 42 of the bamboo-section telescopic sleeve 40 is covered on the connecting head b, and the cross-sectional size of the connecting head b is greater than or equal to the cross-sectional size of the end section sleeve 42 .

[0072] In summary, the technical means of the telescopic clothes-drying rod assembly 100 integrates the fixed clothes-drying rod assembly 101, the movable clothes-drying rod assembly 102 and the electric chain mechanism 30 to form a collaborative system. The fixed clothes-drying rod assembly 101 is composed of two fixed clothes-drying rods 10 and a rod base 20 to form a rectangular frame, providing a stable base for the clothes-drying rod. The movable clothes-drying rod assembly 102 includes a support rod 11 and a cross rod 12. The support rod 11 can be telescoped on the fixed clothes-drying rod 10, and the cross rod 12 enhances the overall load-bearing capacity and stability. The electric chain mechanism 30 is built into the housing 31, and the cross rod 12 is driven by the chain push rod 32 to realize the automatic telescoping of the clothes-drying rod, reducing the labor intensity of manual operation and providing a convenient and fast clothes-drying experience.

[0073] The bamboo-like telescopic sleeve 40 further optimizes the space utilization and storage efficiency of the clothesline assembly. Composed of multiple gradually shrinking sleeves p, each with a decreasing cross-sectional size, it allows for efficient nesting when retracted, saving space and improving compactness. A connector b is secured to the inside of the crossbar 12. Its cross-sectional size is smaller than the window 24 in the housing 31, ensuring smooth insertion and a stable fit. An end sleeve 42, mounted over the connector b, ensures stability and synchronization when the clothesline is fully extended or retracted.
