Description

Technical Field

[0001] This utility model relates to a clothes drying machine, and more particularly to a telescopic drying rod, which expands the amount of clothes that can be dried and reduces the length of the drying rod when stored. Background Technology

[0002] Telescopic clothes drying poles are an important component of modern clothes drying systems. Their main function is to accommodate different amounts of clothing by adjusting the length of the pole. With rising living standards and diverse living environments, traditional fixed-length drying poles can no longer meet the drying needs of all users. Therefore, telescopic drying poles have emerged. Through a built-in mechanical structure, they allow for flexible length adjustment, saving space and improving drying efficiency. The design of telescopic drying poles considers aesthetics, practicality, and durability, making them a preferred solution for modern household clothes drying systems.

[0003] Patent announcement number CN 221254965 U describes a telescopic clothes drying rod, applied for and authorized by Zhejiang Haoyidian Technology Co., Ltd. The core innovation of this patent lies in its unique limiting component design. This component automatically pops out the hanging hole when the secondary drying rod extends and automatically retracts the hanging hole when it retracts, greatly facilitating user operation. When the secondary drying rod is pulled out, the support component automatically pops out outside the secondary drying rod under the action of the pop-up component, forming a "V" shape structure for securing the clothes hanger. When the secondary drying rod is retracted, the support component automatically retracts into the secondary drying rod under the push of the main drying rod. The above-mentioned telescopic drying rod has the following shortcomings and problems:

[0004] 1. The installation of torsion springs requires precise positioning and fixing to ensure that their elastic force can be accurately applied to the support. This increases the complexity and difficulty of the assembly process and demands a high level of skill from the workers.

[0005] 2. As a precision mechanical component, torsion springs have relatively high manufacturing and procurement costs. Furthermore, the complexity of the assembly process can lead to reduced production efficiency and increased scrap rates, further increasing production costs. Utility Model Content

[0039] The 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 protection of the present invention.

[0040] 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.

[0041] like Figure 1 The diagram shown is a schematic representation of the overall structure of the drying rack in this embodiment. The telescopic drying rack 100 mainly includes a hollow main drying rack 20, a primary telescopic rod 30, and a secondary telescopic rod 40. The main drying rack 20 has multiple hanging sections 50 for hanging clothes along its length. The primary telescopic rod 30 is inserted into the end of the main drying rack 20 and includes a hollow primary rod body 31. The secondary telescopic rod 40 is inserted into the end of the primary telescopic rod 30 and includes a secondary rod body 41 and multiple hook assemblies 60 distributed along the length of the secondary rod body 41. This technology, through a three-stage interlocking and limiting design of "outer main rod → first thin rod → second thin rod," breaks through the limitations of mainstream "two-fold" products on the market, achieving a longer extended length and a smaller storage volume, increasing space utilization by up to 50%. Simultaneously, through its unique three-section folding structure, users can flexibly extend and retract the rod length as needed. When fully extended, it provides an extra-long drying distance, easily drying multiple quilts, sheets, curtains, and other large fabrics, meeting the needs of concentrated family drying. When partially retracted, it adapts to daily clothing drying, keeping the balcony passageway unobstructed. When fully retracted, the rod is significantly shortened, greatly saving balcony space and making the environment cleaner and more aesthetically pleasing.

[0042] The hook assembly 60 consists of a base a and a hook b. The base a has a through hole a1, and the hook b is axially connected to one end of the base a. The bottom plate 43 of the secondary rod 41 has a slot o communicating with the inner cavity of the secondary rod 41. The hook assembly 60 is placed inside the secondary rod 41. When the secondary telescopic rod 40 is in the extended state, the hook b passes through the through hole a1 on the base a and the slot o on the bottom plate 43 of the secondary rod 41 by its own weight. When the secondary telescopic rod 40 retracts into the primary telescopic state... When the rod is retracted into the second-stage telescopic rod 30, the hook b is touched by the end of the first-stage telescopic rod 30 and is then stored in the inner cavity of the second-stage rod 41 after passing through the slot o and the through hole a1. The hook b includes a cantilever b1 and a hook part b2. The first end of the cantilever b1 is axially connected to the base a, and the hook part b2 is located at the other end of the cantilever b1. The cantilever b1 can enter the inner cavity of the second-stage rod 41 through the through hole a1 and the slot o. The cross-section of the hook part b2 is triangular, and a triangular hanging hole m is provided inside the hook part b2. This technical means innovatively designs a retractable hook b inside the second thin rod. When the hook b is engaged with the second thin rod, it can be completely retracted and hidden inside the rod body, with a simple and smooth appearance. The user only needs to pull out the thin rod, and the hook b will automatically descend to the working position by gravity or the built-in protrusion structure, without manual operation, which is very convenient. At the same time, protrusions and reserved ribs are designed on the hook b and the limiting rod respectively. The two work together to achieve precise and reliable mechanical limiting, ensuring stability and safety when bearing weight.

[0043] like Figure 2 and Figure 3 The diagram shows a partial structure and enlarged view of the drying rod in this embodiment. A limiting structure L is provided at the end of the first-stage telescopic rod 30 and the front end of the second-stage telescopic rod 40. An end cap 42 is provided at the end of the second-stage telescopic rod 40. The base plate 43 includes a left base plate 44 and a right base plate 45 with slots o. The end of the left base plate 44 has a left vertical plate 44a forming a left groove 44b, and the end of the right base plate 45 has a right vertical plate 45a forming a right groove 45b. The base a has left sliding parts 44c and right sliding parts 45c on both sides that match the left groove 44b and right groove 45b. The base a of the hook assembly 60 is connected end-to-end. The first end of the base a has a groove i, and the second end of the base a has a protruding rib j that engages with the groove i. The clothes hanging component is the hanging groove on the upper surface of the main drying rod 20. This technology increases the load-bearing capacity and stability of the hook b through the triangular cross-section hook b2 structure, preventing clothes from slipping off during drying. At the same time, the hook assembly 60 can be hidden in the inner cavity of the secondary rod 41 when not in use, making the drying rod look simple and smooth, and improving its aesthetics.

[0044] like Figure 4 and Figure 6The diagram shows various states of the clothes drying rod hook b in this embodiment. The telescopic clothes drying rod 100 consists of a hollow main drying rod 20 and a first-stage telescopic rod 30. The main drying rod 20 has multiple hanging parts 50 for hanging clothes along its length. The first-stage telescopic rod 30 is inserted into the end of the main drying rod 20. The first-stage telescopic rod 30 includes a hollow first-stage rod body 31 and multiple hook assemblies 60 distributed along the length of the second-stage rod body 41. The hook assembly 60 consists of a base a and a hook b. The base a has a through hole a1, and the hook b is axially connected to one end of the base a. The bottom plate 43 of the first-stage rod body 31 has a slot o that communicates with the inner cavity of the first-stage rod body 31. The hook assembly 60 is placed inside the first-stage rod body 31. This technology effectively prevents dust and debris from entering the interior of the telescopic rod by setting an end cap 42 at the end of the secondary telescopic rod 40, keeping the drying rod clean and extending its service life. At the same time, the base a has left sliding parts 44c and right sliding parts 45c on both sides that match the left groove 44b and right groove 45b, so that the hook assembly 60 can slide smoothly in the secondary rod body 41, improving the flexibility of use.

[0045] Preferably, when the primary telescopic rod 30 is in the extended state, the hook b passes through the through hole a1 on the base a and the slot o on the bottom plate 43 of the primary rod body 31 by its own weight. When the primary telescopic rod 30 is retracted into the main drying rod 20, the hook b is touched by the end of the main drying rod 20 and is then stored in the inner cavity of the primary rod body 31 after passing through the slot o and the through hole a1. The hook b includes a cantilever b1 and a hook part b2. The first end of the cantilever b1 is axially connected to the base a, and the hook part b2 is located at the other end of the cantilever b1. The cantilever b1 can enter the inner cavity of the secondary rod body 41 through the through hole a1 and the slot o. The cross-section of the hook part b2 is triangular, and a triangular hanging hole m is provided inside the hook part b2. This technical means achieves precise and reliable mechanical limiting through the protrusions and reserved ribs on the hook b and the limiting rod, improves the stability and safety of the hook b when bearing weight, and prevents the hook b from shifting or falling off during use.

[0046] Of course, as a preferred option, one secondary telescopic rod 40 can be reduced, as follows: The telescopic drying rod 100 mainly includes a hollow main drying rod 20 and a primary telescopic rod 30. The main drying rod 20 has multiple hanging parts 50 for hanging clothes along its length. A first-stage telescopic rod 30 is inserted into the end of the main drying rod 20. The first-stage telescopic rod 30 includes a hollow first-stage rod body 31 and multiple hook assemblies 60 distributed along the length of the first-stage rod body 31. The hook assembly 60 consists of a base a and a hook b. The base a has a through hole a1, and the hook b is axially connected to one end of the base a. The bottom plate 43 of the first-stage rod body 31 has a slot o that communicates with the inner cavity of the first-stage rod body 31. The hook assembly 60 is placed inside the first-stage rod body 31. When the first-stage telescopic rod 30 is in the extended state, the hook b passes through the through hole a1 on the base a and the slot o on the bottom plate 43 of the first-stage rod body 31 by its own weight. When the first-stage telescopic rod 30 is retracted into the main drying rod 20, the hook b is touched by the end of the main drying rod 20 and is then stored in the inner cavity of the first-stage rod body 31 after passing through the slot o and the through hole a1.

[0047] The hook b includes a cantilever b1 and a hook b2. The first end of the cantilever b1 is axially connected to the base a, and the hook b2 is located at the other end of the cantilever b1. The cantilever b1 can enter the inner cavity of the primary rod 31 through the through hole a1 and the slot o. The cross-section of the hook b2 is triangular, and a triangular hanging hole m is provided inside the hook b2. This technical approach simplifies the overall structure and reduces production costs by reducing one secondary telescopic rod 40, while retaining the convenient use and stable structure of the telescopic drying rod 100, providing users with a flexible, efficient, and space-saving clothes drying solution.
