Description

Technical Field

[0001] This application relates to the field of clothes drying rack technology, and more specifically, to a clothes drying rack and its drying rack. Background Technology

[0002] Most existing clothes drying racks rely on movable hanging holes for quick clothes collection. When hanging clothes, the hangers need to be placed on the holes, and when collecting the clothes, they need to be removed from the holes, which doesn't actually achieve the goal of quick collection. Other existing technologies use variable clotheslines for quick collection, but clotheslines are not very durable, increasing maintenance costs if incorporated into the drying rack. Utility Model Content

[0003] This application addresses the shortcomings of existing methods by proposing a clothes drying machine and its drying rack to solve the technical problem of unreasonable quick clothes collection structure in related technologies.

[0006] A bracket is orthogonally connected between two parallel drying rods;

[0007] A sliding component is provided on the bracket. When the sliding component slides, it drives the corrugated rod to move horizontally through the linkage component, so that the drying rod switches between a corrugated state and a straight state.

[0008] Optionally,

[0009] The drying rack includes a main rod, a fixed corrugated rod fixedly connected to the main rod, and a movable corrugated rod arranged side by side with the fixed corrugated rod; the movable corrugated rod can translate along the longitudinal axis of the main rod.

[0011] The movable corrugated rod is provided with a linkage component that is linked to the sliding component; the linkage component includes a traction rope connecting the movable corrugated rod and the sliding component, and a reset component disposed between the movable corrugated rod and the bushing.

[0012] Optionally, the fixed corrugated rod and the movable corrugated rod have the same corrugated wavelength; the length of the fixed corrugated rod is greater than that of the movable corrugated rod, and the length difference is N1 times 1 / 2 wavelength; the distance of a single pull of the wire rope is N2 times 1 / 2 wavelength; N1 and N2 are natural numbers, and N1≥N2≥1.

[0013] Furthermore, the linkage also includes a guide wheel assembly, which is configured on the extension trajectory of the traction rope and is used to adjust the assembly direction of the traction rope.

[0014] Alternatively, the bracket and the drying rod are connected by a mounting component, which includes a mounting block for connecting the end of the bracket and a fixing component that forms a through hole on the back of the mounting block for the drying rod to pass through; the linkage component uses the mounting block as the assembly point and includes mounting the guide wheel assembly on the mounting block, and mounting the traction rope and the reset component close to the mounting block.

[0015] Furthermore, the guide wheel assembly includes a first guide wheel pivotally mounted vertically on the back of the mounting block, a second guide wheel pivotally mounted horizontally on the front of the mounting block, and a third guide wheel pivotally mounted horizontally on the front of the mounting block and close to the sliding member; the mounting block has a wire hole through which the traction rope passes.

[0021] (2) The drying rack of this application utilizes the lifting frame to provide translational force for the corrugated rod, so that the two working states of the drying rack can be automatically switched according to the state of the lifting frame.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] refer to Figures 1-8 This application discloses a movable corrugated rod drying rack, comprising a drying rod 1, a bracket 3, and a sliding member. The drying rod 1 includes two corrugated rods capable of relative translation. The bracket 3 is orthogonally connected between the two parallel drying rods 1. The sliding member is mounted on the bracket 3 and drives the corrugated rods to translate via a linkage 16, allowing the drying rod 1 to switch between a corrugated state and a straight state. Furthermore, embodiments of this application are adapted to drying racks for clothes drying machines. The clothes drying machine can be manual or electric. The clothes drying machine typically includes a main unit, a lifting frame 4, and a drying assembly. The main unit controls the extension and retraction of the drying assembly via the lifting frame 4. The drying assembly is functionally differentiated based on the main items to be dried, including at least one of a main drying rack, a telescopic drying rod, and a telescopic quilt drying rod. This application's movable corrugated rod drying rack can serve as the main drying rack or telescopic drying rod of a clothes drying machine. The sliding member on the bracket is connected to the lifting frame 4 and slides under the drive of the lifting frame 4.

[0037] refer to Figures 1-4The drying rod 1 includes a main rod 11, a fixed corrugated rod 12 fixedly connected to the main rod 11, and a movable corrugated rod 13 arranged side by side with the fixed corrugated rod 12. The two ends of the main rod 11, the fixed corrugated rod 12, and the movable corrugated rod 13 are jointly defined by bushings 15. In this embodiment, each bushing 15 includes a main sleeve 151 that is sleeved with the main rod 11, and a secondary sleeve 152 that is connected with the main sleeve 151. The secondary sleeve 152 is used to sleeve the fixed corrugated rod 12 and the movable corrugated rod 13. By defining the bushings 15 at both ends of the main rod 11, the fixed corrugated rod 12 and the movable corrugated rod 13 can be prevented from coming off the main rod 11. Alternatively, the fixed corrugated rod 12 and the movable corrugated rod 13 can be removed from the main rod 11 by disassembling the bushings 15. Furthermore, two parallel sliding grooves 111 are provided on the surface of the main rod 11. The sliding grooves 111 extend along the longitudinal axis of the main rod 11. The sliding grooves 111 are used to fix the corrugated rod 12 and the movable corrugated rod 13, preventing the fixed corrugated rod 12 and the movable corrugated rod 13 from coming out radially along the main rod 11, and limiting the translational trajectory of the movable corrugated rod 13. The sliding grooves 111 are preferably located at the top of the main rod 11, but can also be located on the outer surface of the main rod 11 at other locations, but should be avoided on the downward-facing outer surface.

[0038] like Figure 2 As shown, the fixed corrugated rod 12 and the movable corrugated rod 13 have approximately the same waveform, and the wavelengths of the two waveforms are basically the same. The length of the fixed corrugated rod 12 is greater than that of the movable corrugated rod 13. When the movable corrugated rod 13 translates relative to the fixed corrugated rod 12, the crests and troughs of the two corrugated rods alternately overlap and intersect. When the crests of the two corrugated rods overlap, their troughs also overlap, and the two corrugated rods as a whole form a corrugated shape. The difference in drop between adjacent crests and troughs is the greatest. At this time, it can be considered as the corrugated state of the drying rod 1, and the troughs can be used as a windproof structure for clothes hangers during drying. When the crests and troughs of the two corrugated rods intersect, the troughs of the fixed corrugated rod 12 are filled by the crests of the movable corrugated rod 13, and the difference in drop between adjacent crests and troughs is the smallest. The two corrugated rods as a whole are approximately straight. At this time, it can be considered as the straight state of the drying rod 1, and the clothes hangers scattered on the drying rod 1 can be quickly gathered together manually or electrically. In practical applications, the crests and troughs of the fixed corrugated rod 12 are plateau-shaped, while the crests and troughs of the movable corrugated rod 13 are arc-shaped. Furthermore, the length of the fixed corrugated rod 12 is the same as that of the main rod 11, and the length difference between the fixed corrugated rod 12 and the movable corrugated rod 13 is a multiple of half the wavelength, i.e., N1 times half the wavelength, where N1 is a natural number and N1≥1. This length difference ensures that the movable corrugated rod 13 will completely switch between a corrugated state and a straight state at its initial position and at its translational endpoint. In this embodiment, the movable corrugated rod 13 forms a corrugated state with the fixed corrugated rod 12 at its initial position and a straight state with the fixed corrugated rod 12 at its translational endpoint.

[0039] refer to Figures 4-7 To achieve the translation of the movable corrugated rod 13, in this embodiment, a linkage component 16 is provided, which is linked to the lifting frame 4. This linkage component is used to switch the position of the movable corrugated rod 13 through the regular reciprocating motion of the lifting frame 4. In this embodiment, the lifting frame 4 is a scissor frame. The scissor frame body 41 generally adopts a mesh diamond structure with multiple cross-rotation pivots. When the scissor frame body 41 is extended through the cross-rotation pivots, the overall length of the scissor frame body 41 increases and the width decreases. This causes the sliders 42 on both sides at the bottom of the scissor frame body 41 to move closer to the geometric central axis of the scissor frame. When the scissor frame body 41 is retracted, the overall length of the scissor frame body 41 decreases and the width increases. This causes the aforementioned sliders 42 to move away from the central axis. Typically, the sliders 42 of the scissor frame are confined within the bracket 3. The linkage component 16 includes a traction rope connecting the movable corrugated rod 13 and the lifting frame 4, a reset component 162 connecting the movable corrugated rod 13 and the bushing 15, and a guide wheel assembly for adjusting the assembly direction of the traction rope. Furthermore, the flexibility of the traction rope makes it suitable for applications where the traction force is not applied smoothly. A common and durable steel wire rope 161 can be used. One end of the steel wire rope 161 is fixedly connected to the movable corrugated rod 13, and the other end is connected to the slider 42 in the lifting frame 4. The movement of the slider 42 pulls the steel wire rope 161, further causing the movable corrugated rod 13 to translate. A reset element is provided in the direction of the traction and translation of the movable corrugated rod 13, so that the movable corrugated rod 13 can translate back to its initial position after the tension of the steel wire rope 161 is removed. In this embodiment, a reset spring 162 is selected to suit the installation environment of the reset element. The steel wire rope 161 and the reset spring 162 are hidden inside the drying rod 1. The distance that the steel wire rope 161 pulls the movable corrugated rod 13 to move is at least partially used to overcome the length difference between the movable corrugated rod 13 and the fixed corrugated rod 12, and can realize the switching between the corrugated state and the straight state of the drying rod 1. Therefore, the distance that the steel wire rope 161 pulls at one time should also be a multiple of half the wavelength, that is, N2 times 1 / 2 wavelength, where N2 is a natural number, N1≥N2≥1.

[0040] like Figure 3 As shown, the drying rod 1 can also be equipped with an extension rod 14 via a bushing 15. One possible implementation is that the main rod 11 is hollow to accommodate the extension rod 14 with a smaller outer diameter. The extension rod 14 can be nested inside the main rod 11 as a whole, and can be pulled out from the end of the main rod 11 for a specified length when needed, thereby extending the effective hanging length of the main rod 11.

[0041] refer to Figure 1 , 4 ~8. The bracket 3 and the drying rod 1 are connected by the mounting part 2. A decorative cover 23 can also be configured on the outside of the mounting part 2 to hide and protect the mounting part 2.

[0042] Mounting component 2 includes a mounting block 21 for connecting the end of the bracket 3 and a fixing component 22 assembled on the back of the mounting block 21 to form a ring-shaped buckle. The ring-shaped buckle forms a through hole for the drying rod 1 to pass through. The main unit of the clothes drying machine is connected to the lifting frame 4, the lifting frame 4 is connected to the bracket 3, and the bracket 3 is connected to the drying rod 1, thereby transferring the load borne by the drying rod 1 to the main unit. Mounting component 2 mainly bears the weight of the drying rod 1 and the load of the clothes on the drying rod 1. For this purpose, the fixing component 22 is mainly used to fit tightly against the drying rod 1 and connect the drying rod 1 and the bracket 3 as a whole. The fixing component 22 is a strip-shaped part with an arc-shaped curved structure. The arc-shaped curved structure matches the outer contour of the cross-section of the drying rod 1. The upper end of the fixing component 22 is connected to the upper end of the mounting block 21. In this embodiment, a bolt connection is used. The lower end of the fixing component 22 is connected to the lower end of the mounting block 21. In this embodiment, a hook structure is used for fastening. Mounting block 21 includes a block body 211, with the side of the block body 211 facing the bracket 3 being the front and the side of the block body 211 facing the drying rod 1 being the back. The block body 211 also includes a top plate 212 extending horizontally from its top towards the front, the top plate 212 having a through hole for bolt connection with the fixing member 22; the block body 211 has a wire hole 213 for the wire rope 161 to pass through, a first positioning plate 214 extending horizontally towards the back near the wire hole 213, a second positioning plate 215 extending vertically towards the front near the wire hole 213, and a third positioning plate 216 extending vertically towards the front from the bottom of the block body 211. The first positioning plate 214, the second positioning plate 215, and the third positioning plate 216 are used to assemble the guide wheel assembly, so that the linkage member 16 is assembled with the mounting block 21 as the assembly point, and the wire rope 161 and the return spring 162 are installed close to the assembly point.

[0043] The guide wheel assembly is positioned on the extension trajectory of the wire rope 161 and is used to adjust the assembly direction of the wire rope 161. In this embodiment, the translation direction of the movable corrugated rod 13 and the sliding direction of the slider 42 are intersecting, not on the same straight line or the same plane, and the guide wheel assembly is used to achieve the direction transmission of the pulling force. Specifically, the guide wheel assembly includes a first guide wheel 163 pivotally vertically and a second guide wheel 164 and a third guide wheel 165 pivotally horizontally. The first guide wheel 163 is mounted on the first positioning plate 214 to achieve horizontal turning of the wire rope 161. The second guide wheel 164 is mounted on the second positioning plate 215. After the wire rope 161 passes through the first guide wheel 163 and the wire hole 213, it achieves vertical turning through the second guide wheel 164. The third guide wheel 165 is mounted on the third positioning plate 216 to achieve another vertical turning of the wire rope 161. Furthermore, the third guide wheel 165 is close to the slider 42 of the lifting frame 4 to minimize the angle between the moving trajectories of the wire rope 161 and the slider 42, thereby improving the transmission efficiency of the tension force. On the other hand, the bracket 3 can also be fixed to the mounting part 2 via the third positioning plate 216. Thus, the pivot of the third guide wheel 165 can not only fix the third guide wheel 165 to the third positioning plate 216, but also fix the bracket 3 to the third positioning plate 216 at the same time.

[0044] refer to Figure 5 With mounting block 21 as the assembly point of linkage 16, linkage 16 is mainly assembled near the end of the drying rod 1. With mounting block 21 as the central reference point, wire rope 161 and return spring 162 are respectively assembled on both sides of the central reference point: return spring 162 is assembled in the gap between the end of movable corrugated rod 13 and bushing 15, and the node connecting wire rope 161 and movable corrugated rod 13 is assembled on the other side of the central reference point, away from the end of the drying rod 1. When the wire rope 161 is pulled, it can drive the movable corrugated rod 13 to move to the translation endpoint near the bushing 15 against the elastic force of the return spring 162. When the tension of the wire rope 161 is released, the return spring 162 drives the movable corrugated rod 13 to move back to the initial position. When the movable corrugated rod 13 moves back and forth between the initial position and the translation endpoint, the corrugated state and the straight state of the drying rod 1 are constantly switched. The number of switching or the degree of overlap of the two corrugated rods can be controlled by controlling the lifting amplitude of the lifting frame 4, the moving distance of the wire rope 161 and / or the translation distance of the movable corrugated rod 13.

[0045] Each bracket 3 is equipped with mounting parts 2 on both sides for connecting the drying rod 1, but only one mounting block 21 equipped with a linkage 16 is provided to control the translation of the movable corrugated rod 13. The linkage 16 of the two brackets 3 are respectively mounted on different sides, so the translation direction of the movable corrugated rod 13 in the two drying rods 1 is opposite.

[0046] The specific usage process of this application's movable corrugated rod drying rack, combined with the main unit's lifting control, is as follows:

[0047] When the movable corrugated rod 13 is in its initial position, the wire rope 161 is not under tension, and the return spring 162 is fully extended. At this time, the movable corrugated rod 13 and the fixed corrugated rod 12 form a corrugated state, that is, the corrugations of the movable corrugated rod 13 and the fixed corrugated rod 12 overlap. The slider 42 of the lifting frame 4 is closest to the mounting part 2, and the lifting frame 4 is in a retracted and folded state, that is, the lifting frame 4 is in the position closest to the main unit in the drying state. The trough structure of the corrugated state of the drying rod 1 is used as a windproof structure for the clothes hanger to prevent adjacent clothes from overlapping.

[0048] When the movable corrugated rod 13 reaches its translation endpoint, the wire rope 161 moves at its maximum distance under traction, and the return spring 162 is compressed to its maximum degree. At this point, the movable corrugated rod 13 and the fixed corrugated rod 12 form a straight line, meaning the corrugations of the movable corrugated rod 13 and the fixed corrugated rod 12 are completely intersected. The slider 42 of the lifting frame 4 is furthest from the mounting part 2, and the lifting frame 4 is in an extended state, meaning it is in the position furthest from the main unit during the drying process. When the drying rod 1 is in a straight line, the drop between adjacent crests and troughs is minimal, approximating a straight line, which facilitates the clothes hanger crossing each crest and trough, enabling rapid clothes collection.

[0049] When the lifting range of the lifting frame 4, the moving distance of the wire rope 161 and / or the translation distance of the movable corrugated rod 13 are long enough, the drying rod 1 will undergo more than one gradual switch between corrugated and straight states during the lifting process; the degree of drop between adjacent peaks and troughs can be controlled by controlling the suspension position of the lifting frame 4.

[0050] In other embodiments, the linkage 16 can be replaced by other types of components; the driven structure connected to the linkage 16 can also be selected from other components of the lifting frame 4, or replaced by other power structures. The above-mentioned substitutions do not affect the inventive nature of this application.

[0051] In summary, a drying rack includes: drying rods comprising two corrugated rods capable of relative translation; a bracket orthogonally connected between the two parallel drying rods; and a sliding member disposed on the bracket. When the sliding member slides, it drives the corrugated rods to translate via a linkage, allowing the drying rods to switch between a corrugated state and a straight state. This drying rack utilizes two corrugated rods capable of relative translation and employs a sliding member to provide linkage power, enabling the drying rack to switch between a corrugated state and a straight state, thus simultaneously addressing the needs for wind protection and quick clothes collection.
