It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Embodiment 1

[0040] like Figure 1 and Figure 2As shown, this embodiment provides a clothes drying rod, including a fixed rod 10, a movable rod 20, a limit bracket and a plurality of rolling elements 40. The fixed rod 10 and the movable rod 20 are mutually movably arranged, and there is a movable gap between the fixed rod 10 and the movable rod 20. The limit bracket includes a first limit bracket 30, and the first limit bracket 30 is arranged on the movable rod 20. The rolling element 40 is rollingly arranged on the first limit bracket 30, and the rolling element 40 at least partially protrudes from the first limit bracket 30 and is located in the movable gap. The specific structure of the clothes drying rod described in this embodiment is described in detail below.

[0041] The fixed rod 10 is the main supporting member of the clothes drying rod, and is used to support the movable rod 20 and the clothes to be dried. The movable rod 20 is movably mounted on the fixed rod 10 to flexibly adjust the total length of the clothes drying rod. Figure 1 As shown, the movable rod 20 is movably mounted inside the fixed rod 10, so that when the movable rod 20 is not needed, the movable rod 20 can be pushed into the fixed rod 10 to hide the movable rod 20, which helps to improve the aesthetics and facilitate use. Of course, in other alternative embodiments, the movable rod 20 can be movably mounted outside the fixed rod 10.

[0042] In this embodiment, the fixed rod 10 is a hollow tubular structure. The movable rod 20 can be a solid rod structure. Of course, the movable rod 20 can also be a hollow tubular structure to reduce its weight and manufacturing cost. Preferably, the fixed rod 10 and the movable rod 20 are coaxially arranged. Preferably, the fixed rod 10 and the movable rod 20 are both made by tube extrusion molding.

[0043] In this embodiment, the cross-sectional shapes of the fixed rod 10 and the movable rod 20 are both rectangular, the movable gap between the fixed rod 10 and the movable rod 20 is an annular gap surrounding the movable rod 20, the cross-sectional shape of the annular gap is rectangular, and the first limit bracket 30 can be an annular structure matching the cross-sectional shape of the annular gap. Of course, the first limit bracket 30 can also be a non-annular structure matching the cross-sectional shape of the annular gap. It should be noted that the cross-sectional shapes of the fixed rod 10 and the movable rod 20 are only exemplary and are not limited to rectangles, and can also be elliptical, circular, or other polygons.

[0044] like Figures 2 to 4As shown, the first limit bracket 30 includes a first limit bracket body 31 and a first mounting frame 32. The first limit bracket body 31 is arranged at one end of the movable rod 20 located in the fixed rod 10. The first mounting frame 32 is detachably arranged on the first limit bracket body 31. A rolling element receiving cavity 33 is arranged on the side of the first mounting frame 32 away from the first limit bracket body 31. The rolling element receiving cavity 33 has a first opening. A plurality of rolling elements 40 are rollingly arranged in the rolling element receiving cavity 33. The rolling elements 33 at least partially protrude from the first opening to the first limit bracket body 31 and are located in the movable gap. The design of the first limit bracket body 31 and the first mounting frame 32 helps to simplify the assembly steps of the clothes drying rod, improve the installation efficiency, and facilitate the maintenance of the rolling elements 40. Of course, in other replaceable embodiments, the rolling element receiving cavity 33 can be directly arranged on the first limit bracket 30.

[0045] As an optional embodiment, the first position-limiting bracket body 31 is provided with a first accommodating groove 311 on a side close to the fixed rod 10, and is connected to the movable rod 20 on a side away from the fixed rod 10, and the first mounting frame 32 is arranged in the first accommodating groove 311, and the first opening is exposed from the notch of the first accommodating groove 311. The design of the first accommodating groove 311 is helpful for the assembly and maintenance of the clothes drying rod on the one hand; on the other hand, the first mounting frame 32 can be accommodated in the first accommodating groove 311, which helps to save space and realize the compactness of the clothes drying rod. Of course, in other replaceable embodiments, the first mounting frame 32 can be detachably connected to the first position-limiting bracket body 31 by other detachable means such as screws and buckles. In this embodiment, the first accommodating groove 311 matches the first mounting frame 32, so that the first mounting frame 32 can be clamped in the first accommodating groove 311. Of course, in other replaceable embodiments, the first mounting frame 32 can be fixed in the first accommodating groove 311 by other detachable means such as buckles and screws.

[0046] Preferably, the first receiving groove 311 is formed by being recessed inward from the surface of the first limiting bracket body 31, and the movable rod 20 is provided with an avoidance groove 23 corresponding to the first receiving groove 311, and the first receiving groove 311 is at least partially received in the avoidance groove 23. Through the design of the first receiving groove 311 and the avoidance groove 23, the first receiving groove 311 is partially received in the movable rod 20, which helps to save space and further realize the compactness of the clothes drying rod.

[0047] like Figure 3 and Figure 4As shown, the first position-limiting bracket body 31 is an annular bracket, and the cross-sectional shape of the annular bracket is rectangular, and it is sleeved on one end of the movable rod located in the fixed rod. The structural form of the annular bracket helps to improve the overall structural stability of the clothes drying rod. The first position-limiting bracket body 31 is provided with the first accommodating groove 311 at least on one side located at the upper part of the movable rod 20, and the first mounting frame is correspondingly installed in the first accommodating groove 311. When the movable rod 20 is gradually extended, the end of the movable rod 20 away from the fixed rod 10 will tend to be pressed down under the action of gravity or clothes, and the end of the movable rod 20 located in the fixed rod 10 will press the fixed rod 10 upward, that is, the upper part of the movable rod 20 will be subjected to a large force, and thus the friction resistance is large. Therefore, by arranging the rolling element 40 on the upper part of the movable rod 20, it is helpful to reduce the telescopic movement resistance of the movable rod. Preferably, the first position-limiting bracket body 31 is provided with the first accommodating groove 311 on both sides located at the upper and lower parts of the movable rod 20. Thus, rolling elements are provided at both the upper and lower parts of the movable rod 20, which helps to further reduce the telescopic movement resistance of the movable rod 20. Of course, in other alternative embodiments, it is not limited to setting the first accommodating groove 311 on both sides of the first limiting bracket body 31 located at the upper and lower parts of the movable rod 20, and the first accommodating groove 712 can also be set on any three or four sides of the movable rod. Of course, in other alternative embodiments, the first limiting bracket body 31 is not limited to the annular structure, and the first limiting bracket body 31 can be a bracket unit, which can be set on the upper side of the movable rod, or set on both the upper and lower sides at the same time, and can even be set on any three or four sides of the movable rod. The side of the bracket unit close to the fixed rod 10 is provided with the first accommodating groove 311, and the side away from the fixed rod 10 is connected to the movable rod 20. In this embodiment, the first limiting bracket body 31 and the movable rod 20 are split designs. Of course, in other alternative embodiments, the first limiting bracket body 31 can be designed as an integral part with the movable rod 20.

[0048] In this embodiment, the first limit bracket body 31 is provided with a first engaging protrusion 312 on both the front and rear surfaces close to the movable rod 20, and the movable rod 20 is provided with a first engaging recess 21 corresponding to the first engaging protrusion 312, and the first engaging protrusion 312 matches the first engaging recess 21. Through the cooperation of the first engaging protrusion 312 and the first engaging recess 21, the first limit bracket body 31 is detachably connected with the movable rod 20, and the first limit bracket body 31 constitutes the tail plug of the movable rod 20. Of course, the first limit bracket body 31 can also be connected to the movable rod 20 by other detachable connection methods such as screw fixing and bayonet pins, or the first limit bracket body 31 can also be fixed to the movable rod 20 by welding.

[0049] Furthermore, the first position-limiting bracket body 31 is provided with first strip-shaped through holes 313 extending along the axis direction of the movable rod 20 at positions corresponding to both sides of the first engaging protrusion 312. Through the provision of the two first strip-shaped through holes 313, the region of the first position-limiting bracket body 31 corresponding to the position of the first engaging protrusion 312 has elasticity to move inward and outward, thereby providing sufficient space for the first position-limiting bracket body 31 to be inserted into the movable rod 20, and facilitating the installation of the first position-limiting bracket body 31.

[0050] In this embodiment, a plurality of first sliding support portions 314 are provided on the front and rear surfaces of the first limiting bracket body 31 close to the fixed rod 10. The first sliding support portions 314 are in the shape of long strips and are arranged parallel to the direction of the central axis of the movable rod 20 to reduce the contact area between the first limiting bracket body 31 and the fixed rod 10 and reduce the friction resistance of the telescopic movement of the movable rod 20.

[0051] like Figure 3 , Figure 5 and Figure 6 As shown, the first mounting frame 32 is in the shape of a rectangular parallelepiped. The rolling element receiving cavity 33 is formed by being recessed inwardly on the side of the first mounting frame 32 facing away from the first limiting bracket body 31, and the rolling element 40 is a rolling column. Several rolling columns are arranged in parallel in the rolling element receiving cavity 33 along a direction perpendicular to the central axis of the movable rod 20, and roll in the rolling element receiving cavity 33, and the rolling column at least partially protrudes from the first opening to the first mounting frame 32 and the first limiting bracket body 31. Of course, in other replaceable embodiments, the rolling element 40 can be a spherical ball, at least two rolling element receiving cavities 33 are arranged in parallel to the first mounting frame 32 along the direction of the central axis of the movable rod 20, and several balls are rolled in the rolling element receiving cavity 33, and at least partially protrude from the first opening to the first mounting frame 32 and the first limiting bracket body 31.

[0052] Preferably, the rolling element receiving cavity 33 is annular, and a rolling shaft 34 is arranged at the center of the rolling element receiving cavity 33. The rolling shaft 34 is a waist-shaped protrusion arranged on the inner wall of the rolling element receiving cavity 33, and is arranged perpendicular to the extension direction of the movable rod 20. A plurality of rolling columns are arranged in the rolling element receiving cavity 33 so as to roll around the rolling shaft 34. The rolling column located at the first opening at least partially protrudes from the first opening to the first mounting frame 32 and the first limiting bracket body 31. Through the design of the rolling shaft 34, the rolling column can circulate and roll in the rolling element receiving cavity 33, which helps to more effectively disperse the load. At the same time, during the circulatory rolling process, the rolling column is more evenly worn, which helps to extend the service life of the rolling column. Of course, in other replaceable embodiments, the rolling element accommodating cavity 33 is not limited to the above-mentioned structural form. The rolling element accommodating cavity 33 can be composed of a plurality of arc-shaped grooves arranged on the first mounting frame 32, and the rolling cylinders are rollingly arranged in the arc-shaped grooves one by one, and at least partially protrude from the first mounting frame 32 and the first limiting bracket body 31; or the rolling element accommodating cavity 33 can also be a groove, and a plurality of the rolling cylinders are arranged in sequence and rollingly arranged in the groove, and the rolling cylinders at least partially protrude from the first mounting frame 32 and the first limiting bracket body 31.
