Description

Technical Field

[0001] This utility model relates to the field of clothes drying rack technology, and in particular to a hand-operated clothes drying rack. Background Technology

[0002] To meet people's needs for drying clothes, height-adjustable and foldable clothes drying racks are usually installed on balconies. Currently, there are various types of height-adjustable and foldable clothes drying racks on the market. Based on the driving method, they are divided into manual height-adjustable clothes drying racks and motor-driven height-adjustable and foldable clothes drying racks. Among them, manual height-adjustable clothes drying racks are more popular with consumers due to their lower price.

[0003] For example, Chinese patent CN104911872A discloses a lifting clothes drying rack device, including a single-wheel top seat, a steel wire rope on one side of the single-wheel top seat with one end fixedly connected to the single-wheel top seat; a double-wheel top seat on one side of the steel wire rope with a decorative sleeve fixedly connected to its bottom; a corner device on one side of the decorative sleeve, connected to the double-wheel top seat by a steel wire rope; a lock at the bottom of the corner device; a hand crank at the bottom of the lock; and a drying rod at the bottom of the single-wheel top seat, fixedly connected by a steel wire rope. In this lifting clothes drying rack device, the hand crank and drying rod are directly connected by a steel wire rope. If the user applies excessive force to the hand crank or the drying rod is overloaded, the steel wire rope may break, causing the drying rod to fall and potentially injure nearby users or objects, posing a safety hazard.

[0004] In view of this, the present invention proposes a hand-operated clothes drying machine to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the above-mentioned technology, this utility model provides a hand-operated clothes drying rack with a large load-bearing capacity, reducing the risk of the connecting rope breaking and the rack falling off.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hand-operated clothes drying rack includes a frame. A drive roller and a driven roller are respectively installed at both ends of the frame in the horizontal direction. The centers of the drive roller and the driven roller are connected by a rotating shaft. A connecting rope is wound around the outer circumference of both the drive roller and the driven roller. A hanging bracket is fixedly connected to the bottom of the connecting rope. The frame is also equipped with a beaded chain hand puller. The output end of the beaded chain hand puller is connected to the drive roller for transmission. The beaded chain hand puller is used to drive the drive roller to rotate, causing the connecting rope to raise and lower the hanging bracket. Telescopic brackets for connecting the hanging bracket are provided at the bottom of both ends of the frame. The telescopic brackets can extend and retract along the height direction.

[0008] Preferably, the bead chain hand puller includes a wheel and a bead chain, and the outer circumference of the wheel is evenly provided with a plurality of transmission grooves for the engagement of the beads of the bead chain.

[0009] Preferably, one end of the frame is provided with a first gear shaft, one end of the first gear shaft is connected to the frame through a first bearing, the first gear shaft is connected to the center of the rotating wheel, and an output gear is fixedly connected to the first gear shaft; the center of the drive reel is provided with a second gear shaft extending in the horizontal direction, one end of the second gear shaft is fixedly connected to the rotating shaft rod, and a transmission gear is fixedly connected to the second gear shaft; the output gear and the transmission gear are connected by a reduction gear assembly.

[0010] Preferably, the reduction gear assembly includes a gear bracket and a third gear shaft. The gear bracket includes a mounting surface and a connecting part. The connecting part is used to connect the mounting surface and the frame. A large gear and a small gear are fixedly connected to the third gear shaft. The two ends of the third gear shaft are respectively connected to the frame and the mounting surface through third bearings. The large gear meshes with the output gear, and the small gear meshes with the transmission gear.

[0011] Preferably, an auxiliary gear is fixedly connected to the second gear shaft, and a positioning gear that can rotate relative to the mounting surface is mounted on the mounting surface. The auxiliary gear meshes with the positioning gear. A positioning protrusion is provided on the end face of the positioning gear. A positioning element is provided on the mounting surface. The positioning element extends to the end face of the positioning gear and is used to abut against the positioning protrusion, thereby controlling the length of the connecting rope that the drive reel can take on and release.

[0012] Preferably, the telescopic bracket is provided with multiple rope threading components along the height direction, and the rope threading components are provided with rope holes for connecting ropes to pass through.

[0013] Preferably, the hanger includes two hanging plates and multiple hanging rods extending horizontally, with both ends of the hanging rods fixedly connected to the two hanging plates respectively, and the bottom end of the connecting rope fixedly connected to the hanging plates.

[0014] Preferably, the frame includes two mounting plates spaced apart in the horizontal direction, the drive reel and the bead chain puller are mounted on the same mounting plate, and the driven reel is mounted on the other mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The frame of this utility model is equipped with an active winding wheel, a driven winding wheel, and a beaded chain hand puller. The beaded chain hand puller drives the winding wheel to rotate, causing the connecting rope to rise and fall on the hanging rack, making operation simple. Moreover, both ends of the frame are connected to the hanging rack via telescopic brackets, increasing the load-bearing capacity of the hand-operated clothes drying rack and reducing the probability of the connecting rope breaking. Even if the connecting rope breaks, the frame is connected to the hanging rack via the telescopic brackets to prevent the hanging rack from falling.

[0017] 2. The bead chain hand puller is connected to the drive roller through the output gear, reduction gear assembly, transmission gear, and transmission gear. The power is transmitted through multiple gears, which not only reduces the speed and makes the rotation speed of the drive roller controllable, making the lifting process of the bracket more stable, but also increases the torque through the reduction gear assembly, thereby achieving the effect of saving effort.

[0018] 3. The manual clothes drying rack is equipped with a positioning gear, auxiliary gear, and positioning components to limit movement. The auxiliary gear meshes with the positioning gear, and the positioning protrusion on the positioning gear abuts against the positioning component on the mounting surface. This effectively controls the length of the connecting rope as it is wound up or down by the drive reel, preventing excessive winding or unwinding of the connecting rope and avoiding the hanging rack from rising or falling beyond its reasonable range. This ensures the safety and stability of the overall structure of the clothes drying rack. Attached Figure Description

The auxiliary gear 67 meshes with the positioning gear 68. A positioning protrusion 681 is provided on the end face of the positioning gear 68. A positioning element 682 is provided on the mounting surface 651. The positioning element 682 extends to the end face of the positioning gear 68. The positioning element 682 is used to abut against the positioning protrusion 681, thereby controlling the length of the connecting rope 22 of the drive roller 2, preventing the hanging rack 4 from rising and falling beyond the reasonable range, and ensuring the safety and stability of the overall structure of the clothes drying rack.

[0034] Specifically, the driven reel 3 has a connecting shaft 31 extending horizontally at its center. The rotating shaft 21 has a tubular structure. The connecting shaft 31 and the second gear shaft 63 are inserted into both ends of the rotating shaft 21 and are fixedly connected by screws extending radially along the rotating shaft 21.

[0035] The telescopic bracket 7 is provided with multiple rope threading parts 78 along the height direction. The rope threading parts 78 are provided with rope holes for the connecting rope 22 to pass through. The connecting rope 22 moves in the rope holes of the rope threading parts 78 and can always stay in the correct position without deviation or shaking.

Clothes can be hung on the hanging rods 42 or draped over them.

[0037] The frame 1 includes two mounting plates 11 spaced apart in the horizontal direction. The drive reel 2 and the bead chain hand puller 5 are mounted on the same mounting plate 11, and the driven reel 3 is mounted on the other mounting plate 11. The mounting plates 11 are used for connection to the wall.

[0038] In the utility model, the telescopic bracket 7 is composed of at least two connecting rod assemblies arranged along the height direction, such as... Figure 4 As shown, each linkage assembly includes a first linkage 71 and a second linkage 72. The center of the first linkage 71 and the center of the second linkage 72 are connected by a first pivot 74 to form an X-shaped structure. A rope threading member 78 is disposed on the first pivot 74.

[0039] The upper ends of the topmost first link 71 and second link 72 are further inclined upwards to form an upper connecting portion 73. The mounting plate 11 has a first strip hole 12, and the upper connecting portion 73 is connected to the first strip hole 12 through a first pivot member 74. The lower ends of the bottommost first link 71 and second link 72 are both further inclined downwards to form a lower connecting portion 76. The hanging plate 41 has a second strip hole 411, and the lower connecting portion 76 is also connected to the second strip hole 411 through a second pivot member 75. The upper end of the middle first link 71 is connected to the lower end of the uppermost adjacent second link 72 through a third pivot member 77, and the lower end of the first link 71 is also connected to the upper end of the lowermost adjacent second link 72 through a third pivot member 77, forming a parallelogram structure. The first link 71 and second link 72 are hinged using the parallelogram principle to achieve a telescopic, foldable, and unfoldable effect.
