[0028] Example 1

[0029] like Figures 1 to 3 As shown, this embodiment provides a clothes drying rack, including a fixed rod 10, a movable rod 20, a rolling assembly 30, a first limiting member 40, and a second limiting member 50. The fixed rod 10 and the movable rod 20 are movably sleeved together, with a gap between them. The rolling assembly 30 is disposed in the gap to reduce the frictional resistance of the movable rod 20's telescopic movement relative to the fixed rod 10. The first limiting member 40 and the second limiting member 50 are respectively disposed on the movable rod 20 and the fixed rod 10 to prevent the rolling assembly 30 from leaving the gap. The specific structure of this clothes drying rack will be described in detail below.

[0030] The fixed rod 10 is the main supporting component of the clothes drying rod, used to support the movable rod 20 and the clothes being dried. The movable rod 20 is movably fitted onto the fixed rod 10 to flexibly adjust the overall length of the clothes drying rod. Figure 1 As shown, in this embodiment, the movable rod 20 is movably sleeved inside the fixed rod 10, so that when the movable rod 10 is not needed, it can be pushed into the fixed rod 10 to hide it, which helps to improve aesthetics and facilitate use. Of course, in other alternative embodiments, the movable rod 20 can be movably sleeved outside the fixed rod 10.

[0031] like Figure 2 and Figure 3 As shown, the fixed rod 10 in this embodiment is a hollow tubular structure. The movable rod 20 can be a solid rod structure; however, it can also be a hollow tubular structure to reduce its weight and manufacturing cost. The fixed rod 10 and the movable rod 20 are coaxially arranged. Preferably, both the fixed rod 10 and the movable rod 20 are manufactured by tubular extrusion molding.

[0032] In the embodiment, the fixed rod 10 and the movable rod are both rectangular in cross-sectional shape, the movable gap between the fixed rod 10 and the movable rod 20 is a long strip-shaped rectangular gap, and the shape of the rolling assembly 30 is a flat plate capable of being placed in the rectangular gap. Of course, in other alternative embodiments, the cross-sectional shape of the fixed rod 10 and the movable rod 20 can be circular or elliptical, and correspondingly, the movable gap between the fixed rod 10 and the movable rod 20 can be an arc-shaped gap, and the shape of the rolling assembly 30 is an arc-shaped flat plate capable of being placed in the arc gap.

[0033] In the embodiment, the movable gap between the fixed rod 10 and the movable rod 20 is located on the upper and lower sides opposite to each other, and correspondingly, the rolling assembly 30 is arranged in the movable gap on the upper and lower sides. Of course, in other alternative embodiments, the movable gap between the fixed rod 10 and the movable rod 20 can be arranged on any one of the upper and lower sides or the front and back sides opposite to each other, and can also be arranged on any one of the upper and lower sides and the front and back sides opposite to each other at the same time, or on the upper and lower sides and the front and back sides opposite to each other at the same time. Correspondingly, the rolling assembly 30 is arranged in the movable gap on any one of the upper and lower sides or the front and back sides, or on any one of the front and back sides and the upper and lower sides at the same time, or on the upper and lower sides and the front and back sides at the same time.

[0034] The rolling assembly 30 includes a retainer 31 and a plurality of rolling members 32 arranged in the retainer. Figure 3 and Figure 4 As shown in the drawings, the shape of the retainer 31 is a flat plate, the retainer 31 can be placed in the rectangular gap between the fixed rod 10 and the movable rod 20, and the retainer 31 is arranged along the extension direction of the movable rod 20, that is, the length direction of the retainer 31 is consistent with the extension direction of the movable rod 20. A plurality of through holes 311 are provided through the retainer, the rolling members 32 are arranged to roll in the through holes, and part of the rolling members 32 protrude from at least one side surface of the retainer 31. In the embodiment, part of the rolling members 32 protrude from both side surfaces of the retainer 31, so as to reduce the contact between the retainer 31 and the fixed rod 10 and the movable rod 20 during the extension and retraction movement of the movable rod 20, thereby reducing the frictional resistance of the extension and retraction movement of the movable rod 20, and making the extension and retraction movement of the movable rod 20 more smooth. The through holes 311 provided on the retainer are used to position and constrain the rolling members, so as to avoid mutual interference between the rolling members 32, and the rolling members 32 are arranged to roll between the fixed rod 10 and the movable rod, so as to reduce the frictional resistance between the fixed rod 10 and the movable rod 20.

[0035] In the embodiment, the through holes are arranged in an array along the length direction of the holder 31. The rolling members 32 are uniformly distributed on the holder, thereby helping to bear force, improving the structural stability of the clothes drying rod, and providing a clear and uniform straight rolling path for the rolling of the plurality of rolling members 32, thereby helping to reduce the shaking and deviation of the movable rod 20 during the extension and retraction process and ensuring the stability of the extension and retraction movement of the movable rod 20.

[0036] As preferred, in the length direction of the holder 31, the through holes 311 near the first limiting member 40 are arranged at a first interval 312, and the through holes 311 near the second limiting member 50 are arranged at a second interval 313, and the first interval 312 is greater than the second interval 313. The fixed rod 10 bears the load generated by the extension of the movable rod 20 and the clothes hung thereon through the rolling members 32 on the holder 31. When the movable rod 20 is extended and bears the load generated by the clothes hung thereon, the stress generated by the part of the movable rod 20 in the fixed rod 10 is greater near the second limiting member 50, and the stress gradually disperses along the direction near the first limiting member 40, that is, the stress generated by the movable rod 20 is mainly concentrated near the second limiting member 50. In the embodiment, the arrangement density of the rolling members 32 is increased near the one end of the holder 31 near the second limiting member 50, thereby effectively dispersing the stress concentration generated by the movable rod 20 when the movable rod 20 is extended and bears the load generated by the clothes hung thereon, avoiding the local failure of the movable rod 20 leading to the damage of the overall structure of the clothes drying rod. In other words, the arrangement density of the rolling members 32 is increased near the one end of the holder 31 near the second limiting member 50, thereby enhancing the bearing capacity of the movable rod 20, and thereby ensuring the stability and reliability of the movable rod 20 when the movable rod 20 is extended and used for drying clothes.

[0037] In the embodiment, the opening inner diameter of one end of the through hole 311 is smaller than the outer diameter of the rolling member 32, and the opening inner diameter of the other end of the through hole 311 is greater than the outer diameter of the rolling member 32. The rolling member can be directly placed in the through hole without worrying about falling off, thereby helping to reduce the difficulty of installing the plurality of rolling members 32 on the holder 311, simplifying the installation steps, and improving the installation efficiency. Alternatively, the inner wall of one end of the through hole 311 is provided with a plurality of inwardly protruding protruding portions 314, the opening inner diameter surrounded by the protruding portions 314 is smaller than the outer diameter of the rolling member 32, and the opening inner diameter of the other end of the through hole 311 is greater than the outer diameter of the rolling member 32, as shown in FIG. 4B. The protruding portions 314 can be integrally formed with the holder 31 or arranged on the inner wall of one end of the through hole 311 by welding or the like. Figure 5 As preferred, in the embodiment, the opening inner diameter of one end of the through hole 311 is smaller than the outer diameter of the rolling member 32, and the opening inner diameter of the other end of the through hole 311 is greater than the outer diameter of the rolling member 32. The rolling member can be directly placed in the through hole without worrying about falling off, thereby helping to reduce the difficulty of installing the plurality of rolling members 32 on the holder 311, simplifying the installation steps, and improving the installation efficiency. Alternatively, the inner wall of one end of the through hole 311 is provided with a plurality of inwardly protruding protruding portions 314, the opening inner diameter surrounded by the protruding portions 314 is smaller than the outer diameter of the rolling member 32, and the opening inner diameter of the other end of the through hole 311 is greater than the outer diameter of the rolling member 32, as shown in FIG. 4B. The protruding portions 314 can be integrally formed with the holder 31 or arranged on the inner wall of one end of the through hole 311 by welding or the like.

[0038] As Figure 4 shown in FIG. 9, at least one side surface of the holder 31 is provided with a plurality of sliding support portions 315, which are long strips with their length direction consistent with the length direction of the holder 31, and the height of the sliding support portions 315 is less than the maximum height of the rolling elements 32 protruding from the surface of the holder 31. In this embodiment, both side surfaces of the holder are provided with the sliding support portions. Through the design of the sliding support portions 315, the contact area between the holder 31 and the fixed rod or the movable rod can be reduced, thereby reducing the contact friction. As a preferred, the sliding support portions 315 are arranged between the adjacent through holes 311 along the length direction of the holder 31, which helps to make the force on the holder 31 uniform and provide structural stability of the holder, and when the height of the rolling elements 32 protruding from the surface of the holder 31 is less than the height of the sliding support portions 315, the holder can directly contact the fixed rod 10 or the movable rod 20 through the sliding support portions 315, so as to reduce the contact area between the holder and the fixed rod or the movable rod.

[0039] As Figure 3 shown in FIG. 9, in this embodiment, there are two holders 31, which are arranged in the movable gaps on the upper and lower sides of the movable rod 20 opposite to the fixed rod 10. As mentioned above, the number of the holders can also be one, three or four. It should be noted that when the number of the holders 31 is three or four, they can be designed in one piece and integrated.

[0040] The rolling elements 32 can have various structural forms, such as rollers, wheels, balls, etc. In this embodiment, the rolling elements 32 are spherical balls, and the through holes are circular through holes, in which the balls are arranged one by one. The balls make point contact with the fixed rod 10 and the movable rod 20, which can effectively reduce the friction and make the extension and retraction of the movable rod more smooth. In other embodiments, the rolling elements 32 can be cylindrical rollers, the through holes can be rectangular through holes perpendicular to the extension direction of the movable rod 20, and the rollers are arranged in the rectangular through holes perpendicular to the extension direction of the movable rod 20 and can roll in the through holes towards the extension direction of the movable rod.

[0041] As Figure 3 and Figure 6As shown, the first limiting piece 40 is arranged at one end of the movable rod 20 sleeved in the fixed rod. The first limiting piece 40 in the embodiment is a ring-shaped support, which is sleeved outside the movable rod 20 to limit the retainer 31. Of course, in other alternative embodiments, the first limiting piece 40 is not limited to the structure of the ring-shaped support, and can be a plurality of limiting units arranged on the movable rod 20 one by one corresponding to the retainer 31. In the embodiment, the first limiting piece 40 is designed in a split type with the movable rod 20. Of course, in other alternative embodiments, the first limiting piece 40 can be designed in an integral type with the movable rod 20.

[0042] In the embodiment, the two side inner walls of the first limiting piece 40 are each provided with a clamping protrusion 41, and the movable rod 20 is provided with a clamping recess 21 corresponding to the clamping protrusion 41, and the clamping protrusion 41 matches the clamping recess 21. Through the cooperation of the clamping protrusion 41 and the clamping recess 21, the detachable connection of the first limiting piece 40 and the movable rod 20 is realized, and the first limiting piece 40 constitutes a tail plug of the movable rod. Of course, the first limiting piece 40 can also be connected with the movable rod 20 through other detachable connection modes such as screw fixation, clamping pin, or the first limiting piece 40 can also be fixed on the movable rod 20 through welding.

[0043] As shown in the Figure 6 The first limiting piece 40 is provided with a strip-shaped through hole 42 extending along the axis direction of the first limiting piece 40 at positions corresponding to both sides of the clamping protrusion 41, and the two strip-shaped through holes 42 make the region of the first limiting piece 40 corresponding to the position of the clamping protrusion 41 have a flexible moving range inside and outside, so as to provide sufficient space for the first limiting piece 40 to be sleeved into the movable rod, and facilitate the installation of the first limiting piece 40.

[0044] In the embodiment, the outer surfaces of the front and rear sides of the first limiting piece 40 are each provided with a plurality of second sliding support portions 43, and the second sliding support portions 43 are long strips extending along the central axis direction of the movable rod. The second sliding support portions 43 reduce the contact area between the front and rear sides of the first limiting piece 40 and the fixed rod, and reduce the frictional resistance.

[0045] As shown in the Figure 2 and Figure 7As shown, the second limiting member 50 is disposed at one end of the fixed rod 10 and the movable rod. In this embodiment, the second limiting member 50 is an annular bracket, which is disposed inside the fixed rod 10. The inner diameter of the second limiting member 50 is larger than the outer diameter of the movable rod 20, allowing the movable rod to move freely inside the second limiting member. In this embodiment, a flange 52 is provided on the outer surface of one end of the second limiting member 50, and the flange 52 is connected to the end of the fixed rod 10. The flange 52 facilitates the assembly and disassembly of the second limiting member 50. Preferably, the inner surface of the second limiting member 50 is provided with a plurality of third sliding support portions 51. The third sliding support portions 51 are elongated and extend along the central axis of the movable rod 20 to reduce the contact area between the second limiting member 50 and the movable rod 20, thereby reducing the frictional resistance of the movable rod 20 during telescopic movement.

[0046] like Figure 8 As shown, in this embodiment, the outer diameter of the first limiting member 40 is larger than the outer diameter of the movable rod 20, and smaller than the sum of the outer diameter of the movable rod 20 and the height of the two retainers 31; the inner diameter of the second limiting member 50 is larger than the outer diameter of the movable rod 20, and smaller than the sum of the outer diameter of the movable rod 20 and the height of the two retainers 31. The first limiting member 40 and the second limiting member 50 ensure that the retainers 31 and the rolling member 32 move within the movable gap between the fixed rod 10 and the movable rod 20, while preventing the movable rod 20 from detaching from the fixed rod 10.

[0047] The clothes drying rod includes one fixed rod 10, two movable rods 20, and at least two rolling components 30. The two ends of the fixed rod 10 are respectively movably fitted onto the two movable rods 20, and the at least two rolling components 30 are respectively disposed in the movable gaps between the fixed rod 10 and the two movable rods 20. Preferably, the two movable rods 20 are symmetrically fitted onto the two ends of the fixed rod 10 to ensure the overall balance of the drying rod.

[0048] In assembly, first, the first limiting member 40 is installed, the first limiting member 40 is bent outwardly at a position area corresponding to the clamping protrusion 41, the first limiting member 40 is sleeved into the movable rod 20, then the first limiting member 40 is pushed into and the clamping protrusion 41 is clamped into the clamping recess 21 of the movable rod 20, so that the installation of the first limiting member 40 is completed; then the end portion of the movable rod 20 sleeved with the first limiting member 40 is inserted into the inside of the fixed rod 10, and the retainer 31 installed with the rolling member 32 is inserted into the movable gap between the fixed rod 10 and the movable rod 20, so that the installation of the rolling assembly is completed; finally, the second limiting member 50 is sleeved from the other end of the movable rod 20, the second limiting member 50 is pushed to the fixed rod 10, and the second limiting member 50 is clamped at the end portion of the fixed rod 10, so that the assembly of the clothes drying rod is completed. When it is needed to lengthen the clothes drying rod, the movable rod 20 hidden in the inside of the fixed rod 10 is pulled out, so that the overall length of the clothes drying rod is increased, and the user can dry more clothes. When the amount of clothes is small, the user can push the movable rod 20 into the fixed rod 10, so that the movable rod 20 is hidden in the fixed rod 10, thereby saving space.

[0049] Compared with the prior art, the clothes drying rod provided by the embodiment can increase the retainer and the rolling member in the movable gap between the fixed rod and the movable rod, the through hole formed in the retainer is used to position and constrain the rolling member, the mutual interference between the rolling members is avoided, the rolling contact between the rolling members and the fixed rod and the movable rod reduces the contact friction force, the extension and contraction movement of the movable rod is more smooth, the operation is more convenient, and the use experience of the user is improved.
