Description
Technical Field
[0001] This utility model relates to the field of clothes drying equipment technology, and in particular to a clothes drying rod assembly and a clothes drying machine. Background Technology
[0002] Currently, most retractable clotheslines on the market consist of a clothesline body and a telescopic rod. In practical designs, most telescopic rods achieve length adjustment through relative movement between the telescopic rod and the clothesline body via hard friction. The advantage of this design is its simple structure and low manufacturing cost. However, in actual use, this design has a significant drawback: high resistance during extension and retraction, resulting in a poor user experience.
[0003] To address this issue, some retractable clotheslines incorporate steel balls as rolling elements, transforming hard friction into rolling friction and effectively reducing resistance during extension and retraction. However, adding rolling balls requires installation space. Currently, most retractable clotheslines utilize this space by increasing the inner diameter of the main body and / or decreasing the outer diameter of the telescopic rod. This contradicts the current industry trend towards lightweight and compact design. Therefore, how to utilize the limited space of the clothesline to install rolling elements and improve space utilization is a pressing issue for the industry. Summary of the Invention
[0004] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide a clothes drying rod assembly that can utilize the redundant space inside the clothes drying rod to install rolling parts, thereby saving installation space and improving the space utilization rate of the clothes drying rod assembly.
[0005] This utility model is achieved through the following technical solution: a drying rod assembly, including a drying rod body, a telescopic rod movably connected within the drying rod body, and a rolling assembly; the telescopic rod has a polygonal or near-polygonal cross-section and at least two adjacent sides are provided with a clearance portion, the clearance portion and the inner sidewall of the drying rod body together form a clearance space, and the rolling assembly is in rolling contact with the telescopic rod and the drying rod body respectively within the clearance space.
[0006] Compared with the prior art, the drying rod assembly provided by this utility model has a telescopic rod with a polygonal or polygonal cross-section, and an avoidance part is provided at the connection of at least two adjacent sides. The avoidance part and the inner side wall of the drying rod body together form an avoidance space to accommodate the rolling component. Thus, by using the relatively redundant corner space between the telescopic rod and the drying rod body to accommodate the rolling component, it helps to save installation space and improve the space utilization rate of the drying rod assembly.
[0007] In one embodiment, the lower side of the drying rod assembly has two clearance spaces in the load-bearing direction. The lower side of the drying rod assembly experiences greater friction in the load-bearing direction; therefore, a rolling assembly is provided on its lower side to effectively reduce the frictional resistance during the telescopic movement of the rod.
[0008] In one embodiment, the inner side of the drying rod body is provided with a rolling contact portion corresponding to the avoidance portion, and the rolling contact portion and the avoidance portion together form the avoidance space. By providing a rolling contact portion corresponding to the avoidance portion on the inner side of the drying rod body, instead of the rolling contact between the two adjacent sides of the drying rod body and the rolling assembly, it helps to reduce the frictional resistance of the telescopic rod's telescopic movement.
[0009] In one embodiment, the clearance portion is an inclined surface connecting two adjacent sides of the telescopic rod, and the rolling contact portion is a rolling inclined surface connecting two adjacent sides of the drying rod body. The design of the inclined surface and the rolling inclined surface reduces the frictional resistance of the telescopic rod's extension and retraction, while simultaneously improving the smoothness of the rolling assembly, thereby enhancing the smoothness of the telescopic rod's extension and retraction.
[0010] In one embodiment, the rolling assembly includes a bracket and a plurality of rolling elements; the bracket includes a connecting portion and at least two supporting portions, the supporting portions being correspondingly disposed within the clearance space and connected via the connecting portion; each supporting portion has a plurality of through holes, and the rolling elements are located within the through holes. Connecting the supporting portions together facilitates the installation of the rolling assembly. The through holes on the supporting portions enable the positioning and constraint of the rolling elements.
[0011] In one embodiment, the telescopic rod is a rectangular rod, and there are two clearance spaces, each located on one side of the bottom of the telescopic rod. Correspondingly, there are two support portions, each disposed at one end of the connecting portion, forming a C-shaped structure together with the connecting portion. The C-shaped structure of the bracket prevents the support portions from disengaging from the clearance spaces during the telescopic rod's extension and retraction, thus improving the stability of the rolling elements within the clearance spaces.
[0012] In one embodiment, the bracket is provided with a limiting component for limiting the rolling element; the limiting component includes a plurality of arc-shaped limiting blocks, which are evenly disposed at both ends of the through hole and arranged in a ring around the central axis of the through hole. The inner sidewall of the arc-shaped limiting block matches the contour of the portion of the rolling element protruding from the bracket. The limiting component prevents the rolling element from disengaging, ensuring the stability of the telescopic rod's telescopic movement.
[0013] In one embodiment, four limiting blocks are evenly distributed at both ends of the through hole, and their projections along the central axis of the through hole form a cross shape. This reduces the weight of the bracket while achieving basic limiting of the rolling elements.
[0014] In one embodiment, the clearance portion is a groove formed by an inward recess at the connection point of two adjacent sides of the telescopic rod, and the inner wall of the groove and the inner side wall of the drying rod body together form the clearance space. The groove design provides clearance space while also limiting and guiding the rolling assembly.
[0015] This utility model also provides a clothes drying rack, including the drying rod assembly as described above.
[0016] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] Example 1 like Figures 1 to 4As shown, this embodiment provides a drying rack assembly, including a drying rack body 10, a telescopic rod 20, and a rolling assembly 30. The telescopic rod 20 has a polygonal cross-section, and at least two adjacent sides are provided with clearance portions 21. The clearance portions 21 and the inner sidewall of the drying rack body 10 together form a clearance space 60. The rolling assembly is located within the clearance space 60 and rolls in contact with both the telescopic rod and the drying rack body 10. Therefore, by providing clearance portions 21 at the corners of the telescopic rod 20 and utilizing the relatively redundant corner space between the telescopic rod 20 and the drying rack body 10 to accommodate the rolling assembly 30, installation space is saved, and the space utilization rate of the drying rack assembly is improved. Preferably, in the load-bearing direction of the drying rack assembly, the lower side of the drying rack assembly has two clearance spaces 60. In the load-bearing direction of the drying rack assembly, the lower side has greater friction; providing the rolling assembly 30 on the lower side effectively reduces the frictional resistance of the telescopic rod's telescopic movement. The clearance spaces 60 can be provided on the upper side or the left and right sides of the drying rack assembly, or they can be omitted, depending on the actual situation. In this embodiment, the rolling assembly 30 can be a single set or multiple sets arranged sequentially along the extension direction of the drying rod body 10. The specific number can be determined according to the actual design and is not limited here. Of course, in other alternative embodiments, the cross-section of the telescopic rod 20 is not limited to a polygon, but can also be a polygon-like shape, such as a rounded polygon.
[0021] In this embodiment, the clothes drying rod body 10 is a hollow tubular structure. The telescopic rod 20 can be a solid rod structure; however, it can also be a hollow tubular structure to reduce its weight and manufacturing cost.
[0022] In this embodiment, the inner side of the clothes drying rod body 10 is provided with a rolling contact portion 11 corresponding to the avoidance portion 21, and the rolling contact portion 11 and the avoidance portion 21 together form the avoidance space 60. By providing a rolling contact portion 11 corresponding to the avoidance portion 21 on the inner side of the clothes drying rod body 10, instead of the rolling contact between the two adjacent sides of the clothes drying rod body 10 and the rolling assembly 30, it helps to reduce the frictional resistance of the telescopic rod 20 during telescopic movement. Of course, in other alternative embodiments, the inner side of the clothes drying rod body 10 can also directly roll in contact with the rolling assembly 30.
[0023] In this embodiment, the clearance portion 21 is an inclined surface connecting two adjacent sides of the telescopic rod 20, and the rolling contact portion 11 is a rolling inclined surface connecting two adjacent sides of the drying rod body 10. The design of the inclined surface and the rolling inclined surface reduces the frictional resistance of the telescopic rod 20 during its telescopic movement, while simultaneously improving the smoothness of the rolling assembly 30, thereby enhancing the smoothness of the telescopic rod 20's telescopic movement. Of course, in other alternative embodiments, the clearance portion 21 is not limited to an inclined surface; for example, the clearance portion 21 can be a groove formed by an inward indentation at the connection point of two adjacent sides of the telescopic rod 20, with the inner wall of the groove and the inner sidewall of the drying rod body 10 together forming the clearance space 60. The groove design provides the clearance space 60 while simultaneously limiting and guiding the rolling assembly.
[0024] In one optional embodiment, the outer periphery of the telescopic rod 20 has a chamfered design, and the inclined surface is the chamfered surface of this chamfer. The chamfered design of the telescopic rod 20 itself directly forms the avoidance part 21, which helps to improve production efficiency. Similarly, the inner periphery of the clothes drying rod body 10 has a chamfered design, and the rolling inclined surface is the chamfered surface of this chamfer. The chamfered design of the clothes drying rod body 10 itself directly forms the rolling contact part 11, which helps to improve production efficiency.
[0025] In this embodiment, the rolling assembly 30 includes a bracket 32 and a plurality of rolling elements 31. The bracket 32 includes a connecting portion 321 and at least two supporting portions 322, which are correspondingly disposed within the clearance space 60 and connected by the connecting portion 321. The supporting portion 322 has a plurality of through holes 3221, and the rolling elements 31 are located within the through holes 3221. The supporting portions 322 are connected as a whole by the connecting portion 321, facilitating the installation of the rolling assembly 30. The through holes 3221 on the supporting portion 322 are used to position and constrain the rolling elements 31. Of course, in other alternative embodiments, the rolling assembly 30 may only include a plurality of rolling elements 31; or the rolling assembly 30 may include a plurality of rolling elements 31 and a bracket 32 corresponding to each rolling element 31. In this embodiment, the connecting portion 321 and the supporting portion 322 may be an integral design or a separate design, and are connected by welding, bonding, or snap-fitting.
[0026] In this embodiment, the telescopic rod 20 is a rectangular rod, meaning its cross-section is rectangular. There are two clearance spaces 60, located on opposite sides of the bottom of the telescopic rod 20. Correspondingly, there are two support portions 322, each positioned at one end of the connecting portion 321, forming a C-shaped structure together with the connecting portion 321. The C-shaped structure of the bracket 32 prevents the support portions 322 from disengaging from the clearance spaces 60 during the telescopic movement of the telescopic rod 20, thus improving the stability of the rolling element 31 within the clearance spaces 60. Of course, in other alternative embodiments, the bracket 32 is not limited to a C-shaped structure. Its structure is related to the cross-sectional shape of the clothes drying rod assembly and the number and position of the rolling spaces 60. Taking a clothes drying rod with a rectangular cross-section as an example, if there are two diagonally opposite or three adjacent rolling spaces 60, the bracket 32 corresponds to an L-shaped bracket; if there are four rolling spaces 60, the bracket 32 corresponds to a ring-shaped bracket with a rectangular cross-section, or two opposing C-shaped (or U-shaped) brackets. In this embodiment, a through hole is provided in the middle of the connecting part 321. The weight of the connecting part 321 is reduced through the through hole, thereby reducing the weight of the bracket 32 and facilitating the rolling of the rolling element 31.
[0027] In this embodiment, the bracket 32 is provided with a limiting component for limiting the rolling element 31. The limiting component includes a plurality of arc-shaped limiting blocks 40, which are evenly distributed at both ends of the through hole 3221 and arranged in a ring around the central axis of the through hole 3221. The inner sidewall of the arc-shaped limiting block 40 matches the contour of the portion of the rolling element 31 that protrudes from the bracket 32. The limiting component prevents the rolling element 31 from detaching, ensuring the stability of the telescopic rod 20 during telescopic movement. In this embodiment, the arc-shaped limiting block 40 and the bracket 32 are designed separately and can be connected by means of snap-fit, screws, welding, or bonding; or the arc-shaped limiting block 40 at one end of the through hole 3221 is designed separately from the bracket 32, while the arc-shaped limiting block 40 at the other end of the through hole 3221 is designed as an integral unit, to facilitate the installation of the rolling element 31.
[0028] In one optional embodiment, four arc-shaped limiting blocks 40 are evenly distributed at both ends of the through hole 3221, and their projections along the central axis of the through hole 3221 form a cross shape. This arrangement of four arc-shaped limiting blocks 40 reduces the weight of the bracket 32 while providing basic limiting for the rolling element 31. Of course, in other optional embodiments, the number of arc-shaped limiting blocks 40 can be different, depending on the actual design, and is not limited here.
[0029] In this embodiment, the rolling element 31 is a ball. Of course, in other alternative embodiments, the rolling element 31 can be a roller or a wheel.
[0030] In one optional embodiment, the drying rack assembly includes a drying rack body 10, two telescopic rods 20, and at least two rolling components 30. The two telescopic rods 20 are movably sleeved at both ends of the drying rack body 10, and the at least two rolling components 30 are respectively disposed in the movable gaps between the drying rack body 10 and the two telescopic rods 20. Preferably, the two telescopic rods 20 are symmetrically sleeved at both ends of the drying rack body 10 to ensure the overall balance of the drying rack assembly. Of course, in other optional embodiments, the drying rack assembly may also include a drying rack body 10, a telescopic rod 20, and at least one rolling component 30.
[0031] In some optional embodiments, the drying rack assembly further includes a plug for preventing the telescopic rod 20 from detaching from the drying rack body 10. The plug includes a first plug and a second plug. The first plug is disposed at one end of the telescopic rod 20 that is movably sleeved on the drying rack body 10, and the second plug is disposed at the end of the drying rack body 10 that is movably sleeved on the telescopic rod 20. The rolling assembly 30 is located between the first plug and the second plug. The first and second plugs simultaneously prevent the telescopic rod 20 from detaching from the drying rack body 10 and prevent the rolling assembly from detaching from the drying rack assembly.
[0032] Compared with the prior art, the clothes drying rod assembly provided by this utility model has a polygonal or near-polygonal cross-section for its telescopic rod, and provides a clearance portion at the connection of at least two adjacent sides. The clearance portion and the inner sidewall of the clothes drying rod body together form a clearance space to accommodate the rolling component. Thus, the relatively redundant corner space between the telescopic rod and the clothes drying rod body is used to accommodate the rolling component, thereby saving installation space and improving the space utilization rate of the clothes drying rod.
[0033] Example 2 This embodiment provides a clothes drying rack, including a drying rod assembly as described in Embodiment 1. The main body of the drying rod is connected to the main unit or the ceiling via a connecting structure such as a steel wire rope and a hanging rod. The main unit can drive the drying rod assembly to rise or fall by winding or releasing the steel wire rope.
