Description

Technical Field

[0001] This utility model relates to a drying rack, and more particularly to a rotating multi-purpose drying rack device. Background Technology

[0002] As a common drying device in modern homes, clothes drying racks consist of a main unit and a height-adjustable drying rod assembly. With increasing user demand for more diverse drying functions, the drying rod assembly has gradually diversified into two main functional components: clothes drying rods and quilt drying rods. The clothes drying rods have regularly arranged hanging grooves on their surface, facilitating the stable hanging of clothes on hangers; while the quilt drying rods feature a smooth rod design to accommodate the flat drying of large fabrics such as quilts and sheets.

[0003] For example, the patent document "A drying rod structure and drying rod capable of simultaneously drying clothes and quilts" (publication number CN211772184U) discloses a drying rod structure in which a limiting mechanism is provided on the main connecting rod. When the main quilt drying rod is flush with the main connecting rod, it can abut against the limiting mechanism, thereby realizing the combination of drying clothes and quilts. In addition, the patent document "Manufacturing method of a drying rod structure with dual-mode switchable drying of clothes and quilts" (patent number: CN202323599574) provides a drying rod structure that can switch between drying clothes mode and drying quilt mode. Through the design of rotatable hooks and limiting components, flexible conversion of drying purpose is realized.

[0004] Currently, most mainstream clothes drying racks feature a design with two fixed drying rods, while quilt drying rods typically have an unfoldable and foldable function—the quilt drying rod can be folded away to save space when large items are not needed for drying. However, in actual home use, clothes are dried much more frequently than large items like quilts, especially in winter when the number of clothes to be dried increases dramatically, causing the clothes drying rod to operate under high load for extended periods. In contrast, the quilt drying rod is used less frequently and remains idle most of the time. This imbalance between the load and utilization rate of functional components has become a prominent contradiction restricting the efficiency and user experience of clothes drying racks. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a rotating multi-purpose drying rod that can flexibly switch between drying clothes and drying quilts, thereby solving the problem of functional imbalance between the drying rod and the quilt drying rod in traditional clothes drying machines, realizing multiple uses with one rod, and improving space utilization and usage efficiency.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is: a rotating multi-purpose drying rod device, including two rotating arms and a telescopic drying rod; the rotating arms include a first end and a second end connected to the drying body;

[0007] The retractable drying rack includes a main rod and two retractable support rods. The inner end of the retractable support rod is inserted into the main rod, and the outer end of the retractable support rod is rotatably connected to the second end of the rotating arm.

[0008] Both the telescopic support rod and the main rod have a roughly square cross-section; one of the four sides of the main rod has multiple grooves for hanging clothes hangers, while the other sides are smooth.

[0009] A further preferred embodiment of this utility model is as follows: the second end of the rotating arm is provided with a circular hole, and the outer end of the telescopic support rod extends into the circular hole; the wall of the circular hole is provided with a protrusion, and the outer wall of the telescopic support rod is provided with a concave hole, the protrusion and the concave hole cooperate to position the telescopic drying rod.

[0010] A further preferred embodiment of this utility model is as follows: an expansion plug is provided at the outer end of the telescopic support rod, and a baffle is provided at the second end of the rotating arm; the expansion plug is fixed with a shaft portion, and the shaft portion is rotatably connected to the baffle.

[0011] A further preferred embodiment of this utility model is that the inner end of the telescopic support rod is provided with a bushing to reduce the gap between it and the inner hole of the main rod.

[0012] A further preferred embodiment of this utility model is as follows: the swing arm includes an L-shaped arm and a horizontal joint; the L-shaped arm includes a vertical long rod and a horizontal short rod, the horizontal joint is at a 90-degree angle to the horizontal short rod, and the second end is located on the horizontal joint;

[0013] The swing arm includes a front housing, a rear cover, and a support rod, with the support rod located in the cavity formed by the front housing and the rear cover.

[0014] A further preferred embodiment of this utility model is: it includes two rotating arms and a telescopic drying rod; the rotating arms include a first end and a second end connected to the clothes drying body;

[0015] The retractable drying rack includes a main rod and two retractable support rods. The inner end of the retractable support rod is inserted into the main rod, and the outer end of the retractable support rod is rotatably connected to the second end of the rotating arm.

[0016] The cross-sections of the telescopic support rod and the main rod are both approximately square; among the four sides of the main rod, there is one hanging surface and three smooth surfaces, and the hanging surface is provided with multiple grooves for hanging clothes hangers;

[0017] In the first state, the telescopic support rod rotates so that the hanging surface of the main rod faces upward for hanging clothes; in the second state, the telescopic support rod rotates so that any smooth surface of the main rod faces upward for drying sheets and duvet covers.

[0018] A further preferred technical solution of this utility model is: the first end of the rotating arm is rotatably connected to the rod seat of the clothes drying body, and the rotation of the rotating arm drives the telescopic drying rod to be in a horizontal or vertical state.

[0019] When the swing arm is in a horizontal position, the main rod can switch between a first state and a second state under the drive of the telescopic support rod;

[0020] When the swing arm is in the vertical position, the main rod can switch between the first state and the second state under the drive of the telescopic support rod.

[0021] A further preferred embodiment of this utility model is: the second end of the rotating arm is provided with a circular hole, and the outer end of the telescopic support rod extends into the circular hole;

[0022] The circular hole has a protrusion on its wall, and the retractable support rod has a recess on its outer wall. The protrusion and the recess cooperate to position the retractable drying rod.

[0023] A further preferred embodiment of this utility model is as follows: an expansion plug is provided at the outer end of the telescopic support rod, and a baffle is provided at the second end of the rotating arm; the expansion plug is fixed with a shaft portion, and the shaft portion is rotatably connected to the baffle.

[0024] A further preferred embodiment of this utility model is as follows: the swing arm includes an L-shaped arm and a horizontal joint; the L-shaped arm includes a vertical long rod and a horizontal short rod, the horizontal joint is at a 90-degree angle to the horizontal short rod, and the second end is located on the horizontal joint;

[0025] The swing arm includes a front housing, a rear cover, and a support rod, with the support rod located in the cavity formed by the front housing and the rear cover.

[0026] A further preferred embodiment of this utility model is: it includes a clothes drying body and a rotating multi-purpose clothes drying rod device.

[0027] Compared with existing technologies, the advantages of this invention are: This invention achieves the function of converting a quilt-drying rod into a clothes-drying rod by rotating the retractable support rod to change the orientation of the main rod, thus realizing two uses in one rod. Specifically, one of the four sides of the main rod has multiple grooves for hanging clothes hangers for drying clothes, while the other three sides are smooth surfaces for drying quilts. Users can easily switch the function of the drying rod with one hand: the first state is with the hanging surface facing up for drying clothes; the second state is with the smooth surface facing up for drying quilts. This technology not only eliminates the waste of long-term idle quilt-drying rods but also halves the space required, doubles the load capacity, and simplifies operation, significantly improving the efficiency of the clothes drying rack and the user experience.

[0028] Furthermore, this invention employs an L-shaped frame with a box-like outer shell, making it both lightweight and sturdy. The rotating arm includes an L-shaped arm and a horizontal connector. The vertical long rod of the L-shaped arm is hinged to the main unit, bearing the weight of the entire drying rod; the horizontal short rod extends outward, forming a 90-degree angle with the horizontal connector, creating a Z-shaped clearance structure. The horizontal connector bends the end of the horizontal short rod another 90 degrees, making the rotation axis of the second end parallel to the wall. The front shell and rear cover of the arm, when fastened together, form a closed cavity, with the support rod located inside. The outer shell conceals all screws and sharp corners, providing dustproof, moisture-proof, and anti-pinch protection. This technical solution not only ensures that the drying rod will not collide with the main unit panel or wall during lifting and rotation, but also maximizes the use of balcony space. Users can obtain the same convenient operating angle whether drying horizontally or vertically, further improving the space utilization and ease of operation of the clothes drying rack.

[0029] Furthermore, it should be noted that this invention features a bushing at the inner end of the telescopic support rod. The outer diameter of the bushing maintains a clearance fit with the inner hole of the main rod, while its inner diameter fits snugly against the outer wall of the support rod with zero clearance. The bushing functions similarly to an embedded bearing, significantly reducing friction and wobbling during pushing and pulling, ensuring the drying rod does not sag even when fully extended, and minimizing frictional noise. This not only makes the entire telescopic rod more stable and quieter but also reduces maintenance requirements, making it more durable and easier to use, significantly improving the user experience.

[0041] 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.

[0042] 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 or explained in subsequent figures. For clarity of the structure, the proportions of the components in the figures are not actual proportions.

[0043] like Figure 1 As shown, a rotating multi-purpose drying rack device 10 consists of two rotating arms 11 and a telescopic drying rod 12. The telescopic rod 122 rotates so that the hanging surface v of the main rod 121 faces upwards for hanging clothes, greatly maximizing the usage frequency of the telescopic drying rod 12. The rotating arms 11 are connected to the main unit, and the flip-up connection allows for horizontal low-position or vertical high-position drying. The second end 112 of the rotating arm 11 has a built-in protrusion that locks with the recessed hole b1 on the outer wall of the telescopic rod 122, ensuring that the rotation stops once it reaches the desired position and maintaining the horizontal or vertical position after rotation. This device realizes the dual functions of a clothes drying rod and a quilt drying rod in one unit, making full use of the quilt drying rod's functionality when not in use.

[0044] The L-shaped bend design ensures a precise gap between the main rod 121 and the main unit panel, preventing collisions and hand pinching during lifting and lowering. Users can switch modes with one hand, completely eliminating the waste of long-term idle drying rods, achieving half the space, double the load capacity, and extremely simple operation.

[0045] like Figure 2 , Figure 3 As shown, the second end 112 of the rotating arm 11 is preferably precision-machined into a disc-shaped positioning device. Four elastic protrusions a1 are symmetrically embedded on the wall of its circular hole a, while the outer end b of the telescopic support rod 122 has four concave holes b1 in corresponding positions. When the user holds the main rod 121 and gently rotates it 90°, the protrusion a1 first slides along the conical surface and then "clicks" into the next concave hole b1, forming a lock. This "protrusion a1 and concave hole b1 cooperation mechanism" also features clear tactile feedback, providing a distinct tactile feedback with each 90° rotation, allowing even the elderly and children to confirm the correct positioning by touch.

[0046] The contact surfaces of the protrusion a1 and the concave hole b1 have a certain arc and bevel transition, which can convert a certain vertical load into radial pressure. After locking, it can not shake or make abnormal noise. The protrusion a1 is preferably made of POM self-lubricating material, and the edge of the concave hole b1 is smooth and chamfered, so it can maintain smooth operation without the need for lubricating oil, achieving durable and maintenance-free use.

[0047] With the help of this positioning mechanism, the entire retractable drying rod 12 can be switched between the two states of "the grooved surface v facing up" and "any smooth surface o facing up" with just one hand, solving the problem of repeated disassembly and assembly of traditional folding quilt drying rods.

[0048] like Figure 4 , Figure 5 As shown, the outer end b of the telescopic support rod 122 is a composite component of an integral expansion plug b2 and a rotating shaft b3. The expansion plug b2 is preferably made of elastic nylon material, with three annular reverse teeth on its outer wall. After being pressed into the inner cavity of the support rod, it forms a uniform clamping force, acting as both an anti-detachment end cap and completely sealing the end face of the telescopic support rod 122 to prevent moisture and dust from entering and causing corrosion. The shaft b3 extends integrally from the center of the expansion plug b2. After passing through the center hole of the baffle 113 at the second end 112 of the rotating arm 11, the shaft b3 connects the rotating arm 11, forming a rotating pair. The expansion self-locking and coaxial rotating shaft structure ensures that the main rod 121 remains stable when it is horizontal, vertical, or suspended at any intermediate angle.

[0049] like Figure 2 , Figure 4As shown, a bushing c1 is fitted at the inner end c of the telescopic support rod 122, functioning similarly to an embedded bearing. The outer diameter of bushing c1 maintains a clearance fit with the inner hole of the main rod 121, while its inner diameter fits snugly against the outer wall of the support rod with zero clearance. The material is preferably self-lubricating POM, ensuring almost no wobbling when the telescopic support rod 122 is pushed or pulled, and preventing the drying rod from drooping when extended. This material requires no maintenance or lubrication. It produces minimal friction noise, ensuring quiet operation even when taking in clothes at night, and the entire telescopic rod is stable, quiet, and easy to use.

[0050] like Figure 6 As shown, the rotating arm 11 is designed as an L-shaped frame with a box-like outer shell, which is both lightweight and sturdy. Its key function is to stably hang the entire drying rod on the main unit while providing sufficient clearance for rotation. The vertical long rod d1 of the L-shaped arm 114 is hinged to the main unit and bears the weight of the entire drying rod. The horizontal short rod d2 extends outward and forms a 90° angle with the horizontal connector 115, creating a Z-shaped clearance structure. This ensures that the drying rod will not hit the main unit panel when rising and will not be too far from the wall when lowering, maximizing the utilization of balcony space. The horizontal connector 115 bends the end of the horizontal short rod d2 by another 90°, making the rotation axis of the second end 112 parallel to the wall. This "double bend" keeps the rotation plane of the drying rod at a fixed distance from the wall, allowing users to obtain the same convenient operating angle whether drying horizontally or vertically.

[0051] After the front cover 116 and rear cover 117 of the arm are fastened together, a closed cavity is formed inside, and the support rod 118 is preferably made of high-strength aluminum alloy integral tensile profile and is completely covered. The outer shell not only hides all screws and sharp corners, but also serves to prevent dust, moisture, and pinching. The support rod acts like an "invisible steel beam," evenly distributing the load bending moment throughout the entire swing arm, and it will not deform even after long-term use. Through the double-stage clearance of L-shaped bends and horizontal joints, the swing arm achieves "no hitting the wall or the machine" in a limited space, and the box-shaped outer shell achieves both strength and aesthetics. The entire clothes drying rack looks simpler, holds more, lasts longer, and you don't have to worry about pinching your hands or bumping your head.

[0052] like Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, there are two rotating arms 11 on the left and right, supporting the entire retractable drying rod 12 like two "wrists". The cross-section of the main rod 121 and the two retractable support rods 122 are all "quasi-square". One side is made into a hanging surface v, with a row of grooves v1 arranged equidistantly like a comb, so that the clothes hangers will not slip after being hung. The other three sides are smooth surfaces o, so that quilts and sheets will not be snagged or leave creases when laid out. The four sides have different textures, but share the same wall thickness, saving extra materials. The outer end b of the retractable support rod 122 forms a rotating joint through the second end 112 of the rotating arm 11, with a 90° indexing lock inside. In the first state, the hanging surface v is facing up, becoming a neat clothes hanging area. In the second state, any smooth surface o is facing up, and the flat rod surface becomes a sheet hanging area. The whole process can be completed with one hand, without tools or disassembly, so the elderly and children can operate it.

[0053] When retracted, the telescopic support rod 122 has a short overall length, allowing it to be placed vertically against the wall without obstructing passageways. When extended, it can be rotated in conjunction with the rotating arm 11 to achieve three configurations: low-level hanging of clothes, high-level drying of bedding, and wall-mounted storage. The vertical space of the balcony is fully utilized, solving the pain point of traditional clothes drying racks where "many rods are used but not fully utilized." One rod can be used in four directions, saving space while supporting a large load.

[0054] like Figure 1 ,like Figure 7 , Figure 8 , Figure 9 and Figure 10 The retractable drying rod 12 shown can not only rotate on its own axis, but also rotate around the main rod base 13 together with the rotating arm 11. This dual-axis linkage fully activates the longitudinal and lateral space of the balcony. In the horizontal position, it can achieve low-position full-rod hanging of clothes. With the rotating arm 11 flat, the retractable drying rod 12 is low to the ground, and the user can easily hang clothes by raising their hand. At this time, the main rod 121 can rotate under the drive of the retractable support rod 122. With the grooved surface v facing upward, multiple hanging points are all in place, and multiple clothes can be hung at once. With the smooth surface o facing upward, the retractable support rod 122 is spread out wide and flat to lay out quilts, without bending over or tiptoeing.

[0055] In its vertical position, the rotating arm 11 retracts vertically, and the extendable drying rod 12 rises to below the ceiling, providing ample space below. The rod can still rotate, with the grooved surface (V) facing upwards, allowing for hanging clothes on higher floors without obstructing movement. The smooth surface (O) faces upwards, ensuring long sheets and curtains don't drag on the floor, maximizing sunlight and ventilation. In its folded-out position, the rod retracts completely, and the rotating arm closes, taking up minimal space when flush against the wall, freeing up passageways and natural light in small apartments.
