Description

Technical Field

[0001] This invention relates to the field of clothes drying devices, and more particularly to a symmetrical multi-rod distributed gathering structure. Background Technology

[0002] In the field of clothing drying devices, two parallel fixed drying rods are widely used as the basic load-bearing structure, but they have inherent defects: on the one hand, the drying area provided by the fixed-spaced rods is limited, and multiple clothes are easy to stack and block each other when hanging, affecting the drying efficiency; on the other hand, the fixed structure cannot be retracted when idle, and will continue to occupy a large space, especially unsuitable for small apartments or spaces with limited space.

[0003] To address the aforementioned issues, the industry generally adopts an improved solution that involves adding multiple movable support rods between two fixed drying rods. By allowing the movable support rods to "spread out" to expand the drying area and "fold up" to reduce space usage, a balance between function and space is achieved.

[0004] In existing technologies, such as the clothes drying assembly disclosed in patent number CN212294122U, a support rod dispersing and retracting mechanism is set at the ends of the two fixed drying rods (i.e., the outer side of the rod base). This mechanism limits the distance between the sliders through a steel wire component, thereby realizing the unfolding and retraction of the support rods. However, such solutions have obvious limitations: First, the dispersing and retracting actions of the support rods are limited to the end area of ​​the fixed drying rods, with a limited range of motion, making it difficult to fully utilize the overall length space of the fixed drying rods; second, the connection structure between the steel wire and the sliders requires high installation precision, the assembly process is cumbersome, and the steel wire is prone to deformation or wear under stress during long-term use, affecting stability and leading to a decrease in the positioning accuracy of the support rods. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a symmetrical multi-rod distributed and gathered structure and its usage method; by setting slide rails and limiting rods in sections inside the fixed drying rod, and by cleverly utilizing the matching of the slider and the slide rail and the limitation of the blocking part, the movable drying rod can be flexibly slid and accurately positioned along the overall length direction of the fixed drying rod.

Each movable drying rod has a slider at both ends that is compatible with the second slide rail; The slider of the first movable drying rod is fixedly connected to the first end of the front limiting rod, and the slider is simultaneously located on the second slide rail and can slide along it; the second end of the front limiting rod is provided with a first blocking part extending towards the second slide rail; The second movable drying rod is located inside the first movable drying rod, and its slider is located on the second slide rail and can slide along it. The sliding range is limited by the first blocking part of the front limit rod. The slider of the third movable drying rod is fixedly connected to the first end of the rear limiting rod, and the slider is simultaneously located on the second slide rail and can slide along it; the second end of the rear limiting rod is provided with a second blocking part extending towards the second slide rail; The fourth movable drying rod is located inside the third movable drying rod, and its slider is located on the second slide rail and can slide along it, and the sliding range is limited by the second blocking part of the rear limiting rod.

[0007] A further preferred embodiment of the present invention is as follows: a limiting rod is fixedly provided in the middle restricted section of the first slide rail; the limiting rod includes a first end and a second end; the sliding of the front limiting rod is restricted by the first end, and the sliding of the rear limiting rod is restricted by the second end.

[0008] A further preferred embodiment of the present invention is as follows: when in use, the second movable support rod is pulled to move towards the center, and the front limiting rod is moved to be restricted by the first end of the limiting plug rod through the first blocking part, and the rear limiting rod is moved to be restricted by the second end of the limiting plug rod; the fourth movable support rod is pulled to move towards the center, and the rear limiting rod is moved to be restricted by the second end of the limiting plug rod through the second blocking part; the first movable support rod, the second movable support rod, the fourth movable support rod, and the third movable support rod are relatively evenly distributed between the two fixed drying rods.

[0009] A further preferred embodiment of the present invention is as follows: when retracting, the second movable support rod is pulled outward, and the first end of the front limiting rod is restricted by the first rod seat; the second movable support rod and the first movable support rod move closer together; the fourth movable support rod is pulled outward, and the first end of the rear limiting rod is restricted by the second rod seat; the fourth movable support rod and the third movable support rod move closer together.

[0010] A further preferred embodiment of the present invention is that the movable support rod is provided with a plurality of hooks that can slide along its length.

[0011] A further preferred embodiment of the present invention is as follows: the ends of the two fixed drying rods are fixedly provided with rod seats, and the lower end of the folding frame is connected to the rod seats.

[0012] Another preferred subject: a method of using a symmetrical multi-rod dispersion and gathering structure, in step (1) when the structure is dispersed in use, first pull the second movable drying rod towards the center, so that the slider of the second movable drying rod slides on the second slide rail until the second end of the front limit rod is restricted by the first end of the limit plug rod through the first blocking part; Step (2) Next, pull the fourth movable drying rod towards the center, so that the slider of the fourth movable drying rod slides on the second slide rail until the second end of the rear limit rod is restricted by the second end of the limit plug rod through the second blocking part; Step (3) Through the operations of Step 1 and Step 2 above, the first movable drying rod, the second movable drying rod, the third movable drying rod and the fourth movable drying rod are relatively evenly distributed between the two fixed drying rods, so as to increase the drying area. In step (4), when closing the rod, first pull the second movable drying rod outward so that the first end of the front limit rod is restricted by the first rod seat, thereby bringing the second movable drying rod and the first movable drying rod together. Step (5) Next, pull the fourth movable drying rod outward so that the first end of the rear limit rod is restricted by the second rod seat, thereby bringing the fourth and third movable drying rods together to complete the folding operation and reduce space occupation.

[0013] Another preferred technical solution of the preferred subject is: in step (3), the hooks on the movable drying rod can slide freely along the length of the movable drying rod according to the size and shape of different clothes, so as to realize flexible hanging and drying of clothes.

[0014] Another preferred technical solution for the preferred subject is: in step (1), when pulling the second movable drying rod, a uniform speed should be maintained to avoid being too fast or too slow, so as to ensure the smooth movement of the slider and the limiting rod.

[0015] Another preferred technical solution for the preferred subject is: in step (4), when the second movable drying rod is pulled outward, attention should be paid to whether the first end of the front limit rod reaches the limit position of the first rod seat smoothly. If there is any jamming, the force should be adjusted appropriately or the condition of the slide rail and the slider should be checked. In step (5), when pulling the fourth movable drying rod outward, pay attention to whether the first end of the rear limit rod reaches the limit position of the second rod seat smoothly. If there is any jamming, adjust the force appropriately or check the condition of the slide rail and slider.

[0016] Compared with existing technologies, the advantages of this invention are as follows: The symmetrical multi-rod distributed retraction structure provided by this invention, by setting slide rails and limiting rods in sections inside the fixed drying rod, allows the four movable drying rods to slide flexibly and be precisely positioned along the overall length of the fixed drying rod. This effectively overcomes the limitations of existing technologies where movable support rods can only be dispersed and retracted in the end area, resulting in low space utilization. It significantly increases the drying area and avoids clothes piling up. At the same time, the mechanical structure of direct matching between sliders and slide rails replaces the traditional steel wire connection, reducing the installation accuracy requirements, simplifying the assembly process, and avoiding stability problems caused by steel wire deformation or wear. This significantly improves structural reliability and service life, making it particularly suitable for small apartments and other space-constrained scenarios. Attached Figure Description

Detailed Implementation

[0019] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0020] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0021] like Figures 1 to 6 As shown, a symmetrical multi-rod distributed gathering structure 100 is provided on the clothes drying rack 200. This invention aims to provide a detailed description of the symmetrical multi-rod distributed gathering structure 100. This structure mainly consists of two parallel fixed drying rods 10 and four independently set movable drying rods 20. The fixed drying rods 10 serve as the basic framework of the entire structure. Inside, two parallel slide rails are cleverly arranged along the length direction, namely the first slide rail 11 and the second slide rail 12. The first slide rail 11 is located outside the second slide rail 12. This specific slide rail layout provides a solid foundation for the flexible movement and precise positioning of the movable drying rods 20. The specific solution will be described below.

[0022] The first slide rail 11 is divided into three sections along its length: a front section 11a, a middle restricted section 11b, and a rear section 11c. The middle restricted section 11b defines the sliding boundaries of the front and rear sections, thereby ensuring the orderly operation and precise control of the entire slide rail system.

[0023] Inside the front section 11a, a front limiting rod 01 is cleverly designed, which can slide freely along the length of the front section 11a. This technology allows the front limiting rod 01 to be flexibly adjusted in position according to actual usage needs, providing precise guidance and positioning for the dispersing and retracting of the movable drying rack 20.

[0024] Similarly, a rear limit rod 02 is also installed inside the rear section 11c, which can also slide along the length of the rear section 11c. The presence of the rear limit rod 02 further improves the function of the entire slide rail system, working in conjunction with the front limit rod 01 to achieve precise control and stable support of the movable drying rod 20.

[0025] When it is necessary to distribute the movable drying rods 20 to increase the drying area, pulling the second movable drying rod 20b towards the center will move the front limiting rod 01 until it is restricted by the first end 31 of the limiting plug rod 30. Simultaneously, pulling the fourth movable drying rod 20d towards the center will move the rear limiting rod 02 until it is restricted by the second end 32 of the limiting plug rod 30. In this way, the four movable drying rods 20 (20a, 20b, 20c, 20d) can be relatively evenly distributed between the two fixed drying rods 10, thereby maximizing the drying area.

[0026] When it is necessary to fold up the movable drying rod 20 to reduce space occupation, pulling the second movable drying rod 20b outward will cause the first end of the front limit rod 01 to be restricted by the first rod seat 41, bringing the second movable drying rod 20b and the first movable drying rod 20a together. Simultaneously, pulling the fourth movable drying rod 20d outward will cause the first end of the rear limit rod 02 to be restricted by the second rod seat 42, bringing the fourth movable drying rod 20d and the third movable drying rod 20c together. In this way, the movable drying rods 20 can be tightly closed in the folded state, reducing space occupation.

[0027] In the symmetrical multi-rod distributed gathering structure 100 of the present invention, each movable drying rod 20 has a specific configuration, with sliders 21 at both ends that are precisely adapted to the second slide rail 12. These sliders 21 not only ensure that the movable drying rod 20 can slide smoothly on the second slide rail 12, but also, in some cases, achieve precise control of the position of the movable drying rod 20 through a clever connection with a limiting rod.

[0028] Specifically, the slider 21 of the first movable drying rod 20a is tightly connected to the first end of the front limit rod 01 via a fixed connection. This fixed connection ensures that when the front limit rod 01 slides along the front section 11a of the first slide rail 11, the first movable drying rod 20a can move synchronously. Simultaneously, the slider 21 is also located on the second slide rail 12 and can slide freely along the length of the second slide rail 12. This dual sliding mechanism allows the first movable drying rod 20a to be guided by the front limit rod 01 during movement while maintaining a stable sliding trajectory on the second slide rail 12.

[0029] Furthermore, such as Figure 8As shown, the second end of the front limiting rod 01 is provided with a first blocking part 011 extending towards the second slide rail 12. This first blocking part 011 plays a crucial role in the structure. When the second movable drying rod 20b moves towards the center, its slider 21 contacts the first blocking part 011, thus limiting its sliding range. This not only ensures the orderly movement of the movable drying rods 20 during the dispersing and retracting process, but also prevents excessive stacking or misalignment between the movable drying rods 20 through physical blocking, further improving the stability and reliability of the entire structure.

[0030] Furthermore, the second movable drying rod 20b is located inside the first movable drying rod 20a, and its two end sliders 21 are both mounted on the second slide rail 12, allowing it to slide freely along the length of the second slide rail 12. This enables the second movable drying rod 20b to move flexibly on the second slide rail 12 to adapt to different drying needs. To ensure effective control of the sliding range of the second movable drying rod 20b, its sliding range is limited by the first blocking part 011 of the front limit rod 01. When the second movable drying rod 20b moves towards the center, its sliders 21 will contact the first blocking part 011, thereby being restricted to a certain position to prevent excessive movement and ensure the stability and reliability of the structure.

[0031] The slider 21 of the third movable drying rod 20c is fixedly connected to the first end of the rear limiting rod 02. This fixed connection ensures that the third movable drying rod 20c can move synchronously when the rear limiting rod 02 slides along the rear section 11c of the first slide rail 11. Simultaneously, the slider 21 of the third movable drying rod 20c is also located on the second slide rail 12 and can slide freely along the length of the second slide rail 12. This dual sliding mechanism not only ensures the flexibility of movement of the third movable drying rod 20c but also achieves precise control of its position through its connection with the rear limiting rod 02. The second end of the rear limiting rod 02 is provided with a second blocking part 021 extending towards the second slide rail 12. This second blocking part 021 plays an important limiting role in the structure.

[0032] The fourth movable drying rod 20d is located inside the third movable drying rod 20c. Its two end sliders 21 are also mounted on the second slide rail 12 and can slide freely along the length of the second slide rail 12. This allows the fourth movable drying rod 20d to move flexibly on the second slide rail 12 to adapt to different drying needs. To ensure effective control of the sliding range of the fourth movable drying rod 20d, its sliding range is limited by the second blocking part 021 of the rear limit rod 02. When the fourth movable drying rod 20d moves towards the center, its sliders 21 contact the second blocking part 021, thus being restricted to a certain position to prevent excessive movement and ensure the stability and reliability of the structure.

[0033] Each movable drying rod 20's slider 21 can slide freely along the second slide rail 12, and through its fixed connection with the limiting rod, precise control of the movable drying rod 20's position is achieved.

[0034] Furthermore, in the symmetrical multi-rod dispersion and retraction structure 100 of the present invention, the middle restricted section 11b of the first slide rail 11 plays a crucial role. This section not only serves as a physical isolation area to prevent the sliding components of the front section 11a and the rear section 11c from interfering with each other, but also has a key component fixedly installed—the limiting stop rod 30. The design of the limiting stop rod 30 is one of the core components that enables the entire structure to precisely control the dispersion and retraction actions of the movable drying rod 20.

[0035] The limiting stop rod 30 is fixed in the intermediate restricted section 11b. Its structure includes two main parts: a first end 31 and a second end 32, which precisely limit the sliding range of the front limiting rod 01 and the rear limiting rod 02, respectively. Specifically: When the slider 21 of the first movable drying rod 20a drives the front limit rod 01 to slide along the front section 11a of the first slide rail 11, the sliding range of the front limit rod 01 is limited by the first end 31 of the limit stop rod 30. This means that the front limit rod 01 will stop sliding further when it reaches the first end 31, thereby ensuring that the first movable drying rod 20a can be accurately positioned in the dispersed state and will not exceed the predetermined range.

[0036] Similarly, when the slider 21 of the third movable drying rod 20c drives the rear limiting rod 02 to slide along the rear section 11c of the first slide rail 11, the sliding range of the rear limiting rod 02 is limited by the second end 32 of the limiting plug rod 30. This ensures that the rear limiting rod 02 can stop accurately when it reaches the second end 32, so that the third movable drying rod 20c can be accurately positioned even in a dispersed state, maintaining the symmetry and stability of the entire structure.

[0037] When the clothes drying rack is in use and the movable drying rods need to be spread out to increase the drying area, the operation process is as follows: First, gently pull the second movable drying rod 20b to move it smoothly towards the center along the second slide rail 12. As the second movable drying rod 20b moves, its slider 21 will contact the first blocking part 011 of the front limit rod 01, thereby causing the front limit rod 01 to slide towards the center along the front section 11a of the first slide rail 11. The movement of the front limit rod 01 will continue until it is restricted by the first end 31 of the limit stop rod 30, ensuring that the front limit rod 01 is accurately positioned at the predetermined position.

[0038] Simultaneously, the fourth movable drying rod 20d is pulled, causing it to move towards the center along the second slide rail 12. The slider 21 of the fourth movable drying rod 20d will contact the second blocking part 021 of the rear limit rod 02, thereby causing the rear limit rod 02 to slide towards the center along the rear section 11c of the first slide rail 11. The movement of the rear limit rod 02 will continue until it is restricted by the second end 32 of the limit plug rod 30, ensuring that the rear limit rod 02 is accurately positioned in the predetermined position.

[0039] Through this series of coordinated actions, the first movable drying rod 20a, the second movable drying rod 20b, the third movable drying rod 20c, and the fourth movable drying rod 20d can be relatively evenly distributed between the two fixed drying rods 10. At this time, the drying area of ​​the clothes drying rack is maximized, and the clothes can be hung evenly, avoiding stacking and obstruction, thus significantly improving drying efficiency.

[0040] When the clothes drying rack is not in use and the movable drying rod needs to be folded up to reduce space usage, the operation process is as follows: First, gently pull the second movable drying rod 20b to move it outward along the second slide rail 12. As the second movable drying rod 20b moves, the first end of the front limit rod 01 will gradually approach the first rod seat 41. When it reaches a certain position, the first end of the front limit rod 01 will be restricted by the first rod seat 41, thus stopping further movement. At this time, the second movable drying rod 20b and the first movable drying rod 20a will be closely close together, forming a compact unit.

[0041] Next, pull the fourth movable drying rod 20d, causing it to move outward along the second slide rail 12. As the fourth movable drying rod 20d moves, the first end of the rear limit rod 02 gradually approaches the second rod seat 42. When it reaches a certain position, the first end of the rear limit rod 02 is restricted by the second rod seat 42, thus stopping further movement. At this point, the fourth movable drying rod 20d and the third movable drying rod 20c will be closely brought together, forming another compact unit.

[0042] Preferably, in the symmetrical multi-rod distributed gathering structure of the present invention, multiple hooks are cleverly provided on the movable drying rod 20. These hooks can slide freely along the length of the movable drying rod 20, providing great convenience to the user. Users can flexibly adjust the position of the hooks according to the size and shape of different garments to ensure that each garment receives the best drying effect. Whether it is long or short clothing, the position of the hooks can be adjusted to accommodate various drying needs, allowing the clothes dryer to meet diverse drying requirements.

[0043] In addition, the fixed drying rod 20 is equipped with multiple hanging slots 24, which provide users with additional drying options, further increasing the flexibility and versatility of drying. Users can choose to use the hanging fasteners on the movable drying rod 20 or the hanging slots 24 on the fixed drying rod 20 as needed, making the clothes drying rack more convenient to use, better adaptable to different drying scenarios, and meeting the daily drying needs of the family.

[0044] More preferably, the ends of the two fixed drying rods 10 are fixedly provided with rod seats 40. The stability of the rod seats 40 ensures the stability of the clothes drying machine during use, and can maintain the balance and firmness of the structure even when hanging heavy clothes.

[0045] In addition, the lower end of the folding rack 60 is connected to the rod base 40. This connection method allows the clothes dryer to be easily folded and stored when not in use, greatly reducing space occupation, which is especially suitable for small apartments or living environments with limited space.

[0046] This invention provides a method for using a symmetrical multi-rod dispersion and retraction structure. This method, through a series of coordinated operational steps, achieves flexible dispersion and retraction of the movable drying rods, improving drying efficiency and saving space. The specific steps are as follows: Step (1): When using the diffused state, first gently hold the second movable drying rod 20b and pull it smoothly towards the center, so that the slider 21 of the second movable drying rod 20b slides on the second slide rail 12 until the second end of the front limit rod 01 is restricted by the first end 31 of the limit plug rod 30 through the first blocking part 011. During the pulling process, a uniform speed should be maintained to avoid being too fast or too slow, so as to ensure the smooth movement of the slider 21 and the front limit rod 01.

[0047] Step (2): Next, gently hold the fourth movable drying rod 20d and pull it smoothly towards the center so that the slider 21 of the fourth movable drying rod 20d slides on the second slide rail 12 until the second end of the rear limit rod 02 is restricted by the second end 32 of the limit plug rod 30 through the second blocking part 021.

[0048] Step (3): Through the operations of steps (1) and (2) above, the first movable drying rod 20a, the second movable drying rod 20b, the third movable drying rod 20c, and the fourth movable drying rod 20d can be relatively evenly distributed between the two fixed drying rods 10, thereby maximizing the drying area and avoiding the stacking of clothes. In this state, the hooks 50 on the movable drying rod 20 can slide freely along the length of the movable drying rod 20 according to the size and shape of different clothes, realizing flexible hanging and drying of clothes.

[0049] Step (4): When closing the rod, first gently grasp the second movable drying rod 20b and pull it outwards smoothly so that the first end of the front limit rod 01 is restricted by the first rod seat 41. During the pulling process, observe whether the first end of the front limit rod 01 reaches the restricted position of the first rod seat 41 smoothly. If there is any jamming, adjust the force appropriately or check the status of the slide rail 12 and the slider 21. At this time, the second movable drying rod 20b and the first movable drying rod 20a will be tightly close together.

[0050] Step (5): Next, gently grasp the fourth movable drying rod 20d and pull it outwards smoothly, so that the first end of the rear limit rod 02 is restricted by the second rod seat 42. During the pulling process, pay attention to whether the first end of the rear limit rod 02 reaches the restricted position of the second rod seat 42 smoothly. If there is any jamming, adjust the force appropriately or check the status of the slide rail 12 and the slider 21. At this time, the fourth movable drying rod 20d and the third movable drying rod 20c will come together tightly, completing the folding operation and reducing space occupation.

[0051] Through the above steps, the symmetrical multi-rod dispersion and retraction structure of the present invention not only realizes the flexible dispersion and retraction of movable drying rods, but also further improves the flexibility and adaptability of drying through the flexible design of the fasteners.
