Abstract
Description
Technical Field
[0001] This utility model relates to a clothes drying device, and more specifically, to a hand-cranked clothes drying pole. Background Technology
[0002] Existing clotheslines are mainly of two types: fixed and electric. Fixed clotheslines are in a fixed position and their height is not adjustable, making them inconvenient to use. While electric clotheslines can raise and lower, they are more expensive and require electricity, so they may not function properly during power outages. Existing electric clotheslines use a motor to raise and lower the clothesline, which results in complex structures and high installation and maintenance costs. In addition, some older residential areas or temporary residences may not have the conditions for installing electric clotheslines. Therefore, there is a need for a simple, height-adjustable, and easy-to-use hand-cranked clothesline.
[0003] This invention can reduce the wear of steel wire ropes and enable manual adjustment of the height of clothes drying poles. Utility Model Content
[0004] The present invention aims to solve the technical problems mentioned in the background art and provide a hand-cranked clothes drying pole that reduces the wear of the steel wire rope and allows for manual adjustment of the height of the clothes drying pole.

[0006] The pulley assembly includes: a pulley base, a pulley bracket, a top cover, and a pulley body. The pulley base is installed at the top of the clothesline, and the top of the pulley base is fixedly mounted on the wall. The pulley bracket is fixedly connected to the bottom of the pulley base, and the top cover is fixedly connected to the bottom of the pulley bracket. The pulley body is rotatably connected to the center of the pulley bracket. A first wire-passing hole is opened at the bottom of the pulley base, and a second wire-passing hole is opened through the center of both the top and bottom of the pulley bracket. The top cover is a concave disc shape, and a third wire-passing hole is opened through the center of the top cover. The steel wire rope passes through the second wire-passing hole.
[0007] A further preferred embodiment: The universal corner unit comprises a fixed base, a rotating shaft, and a wire guide ball. The fixed base is installed on the left side of the pulley assembly. The top of the fixed base is fixedly installed on the wall. The bottom of the fixed base is rotatably connected to the rotating shaft. The bottom of the rotating shaft is fixedly connected to the wire guide ball, and a fourth wire guide hole is opened inside the wire guide ball.
[0008] A further preferred embodiment: The hand-cranked box includes a winding roller, a worm gear, a rotating rod, a support block, a bevel gear set, a worm, and a housing. The rotating rod is fixedly connected to the left end of the handle. The support block is rotatably connected to the center of the rotating rod. The housing is fixedly connected to the top of the support block. The bevel gear set is fixedly connected to the left end of the rotating rod. The bevel gear set includes two bevel gears that mesh perpendicularly with each other. The other bevel gear in the bevel gear set is fixedly connected to a worm. The top and bottom ends of the worm are rotatably connected to the housing. A worm gear meshes with each of the front and rear ends of the worm gear. The winding roller is fixedly connected to the center of the worm gear. The left and right ends of the winding roller are rotatably connected to the housing. A steel wire rope is connected to the center of the winding roller.
[0009] A further preferred embodiment: the lead angle of the worm gear is smaller than the equivalent friction angle between the gears.
[0010] A further preferred embodiment: the upper end of the hanging ball is divided into an outer rectangular parallelepiped shape, the lower end is a ring shape with a notch at the bottom, and the top of the clothes drying rod is a cylinder shape that fits with the bottom end of the hanging ball.
[0011] A further preferred embodiment: the clothesline has several equally spaced hanging holes.
[0012] A further preferred embodiment: a limit block is provided on the steel wire rope at the top of the hand-cranked box.
[0013] A further preferred embodiment: the clothes drying rod is provided with plugs at both ends.
[0014] Beneficial effects:
[0015] 1. By incorporating a pulley assembly and a universal joint, the wear of the wire rope is reduced. After exiting the hand-cranked box, the wire rope first passes through the fourth through-hole on the guide ball. The guide ball is fixedly connected to the rotating shaft, allowing it to rotate with the shaft and giving the device a universal joint function. The wire rope then passes through the first through-hole, then through the second through-hole at the top of the pulley bracket, pressing against the pulley. It then passes through the second through-hole at the bottom of the pulley bracket and finally exits through the third through-hole in the center of the top cover, before being connected to the hanging ball. The rotatable guide ball and pulley reduce friction between the devices, increasing the service life of the wire rope.
[0016] 2. The system features a hand crank, allowing for manual adjustment of the clothesline height. In use, turning the handle rotates the rotating rod, which in turn drives the worm gear via a bevel gear set. The worm gear then drives the worm wheel, which in turn drives the winding roller, causing the wire rope to wind onto or detach from the winding roller, thus adjusting the clothesline height. Since the worm's lead angle is less than the equivalent friction angle between the gears, the worm can drive the worm wheel, but the worm wheel cannot drive the worm, ensuring the clothesline remains in the designated position and does not move downwards due to its own weight.
[0017] 3. In summary, this type of hand-cranked clothes drying rack, with its pulley assembly, universal corner mechanism, and hand crank, can reduce wear on the wire rope and allow for manual adjustment of the rack's height. Attached Figure Description

[0027] The pulley assembly 2 includes: a pulley base 201, a pulley bracket 202, a top cover 203, and a pulley body 204. The pulley base 201 is mounted on the top of the clothesline 1, and the top of the pulley base 201 is fixedly mounted on the wall. The pulley bracket 202 is fixedly connected to the bottom of the pulley base 201, and the top cover 203 is fixedly connected to the bottom of the pulley bracket 202. The pulley body 204 is rotatably connected to the center of the pulley bracket 202. A first through hole for wires is provided at the bottom of the pulley base 201. The top and bottom ends of the frame 202 are provided with a second through hole. The top cover 203 is a concave disc shape. The top cover 203 is provided with a third through hole. The wire rope 3 passes through the second through hole. The wire rope 3 passes through the first through hole, then through the second through hole at the top of the pulley bracket 202, presses on the pulley, then passes through the second through hole at the bottom of the pulley bracket 202, and finally comes out from the third through hole in the center of the top cover 203 and is then connected to the hanging ball 8.
[0028] In this embodiment of the utility model, the universal corner device 4 consists of a fixed base 401, a rotating shaft 402, and a wire guide ball 403. The fixed base 401 is installed on the left side of the pulley assembly 2. The top of the fixed base 401 is fixedly installed on the wall. The bottom of the fixed base 401 is rotatably connected to the rotating shaft 402. The bottom of the rotating shaft 402 is fixedly connected to the wire guide ball 403. The wire guide ball 403 has a fourth wire through hole. After the steel wire rope 3 comes out of the hand-cranked box 6, it first passes through the fourth wire through hole on the wire guide ball 403. The wire guide ball 403 is fixedly connected to the rotating shaft 402, so that the wire guide ball 403 can rotate with the rotating shaft 402, thus giving the device the function of universal cornering.
[0029] In this embodiment of the utility model, the hand-cranked box 6 includes a winding roller 601, a worm gear 602, a rotating rod 603, a support block 604, a bevel gear set 605, a worm 606, and a housing. The rotating rod 603 is fixedly connected to the left end of the handle 7. The support block 604 is rotatably connected to the center of the rotating rod 603. The housing is fixedly connected to the top of the support block 604. The bevel gear set 605 is fixedly connected to the left end of the rotating rod 603. The bevel gear set 605 includes two mutually perpendicular meshing bevel gears. The other bevel gear of the bevel gear set 605 is fixedly connected to the worm 606. The top and bottom ends of the worm 606 are rotatably connected to the housing. Each end of the wheel 602 is engaged with a worm gear 602. A winding roller 601 is fixedly connected to the center of the worm gear 602. The left and right ends of the winding roller 601 are rotatably connected to the outer casing. A steel wire rope 3 is connected to the center of the winding roller 601. In use, the handle 7 is turned, which drives the rotating rod 603 to rotate. Then, the rotating rod 603 drives the worm gear 606 to rotate through the bevel gear set 605. The worm gear 606 drives the worm gear 602 to rotate. Then, the worm gear 602 drives the winding roller 601 to rotate, so that the steel wire rope 3 is wound on the winding roller 601 or unwound from the winding roller 601, thus completing the height adjustment of the clothes drying rod 1.
[0030] In this embodiment of the utility model, the lead angle of the worm 606 is smaller than the equivalent friction angle between the gears, so that the worm 606 and the worm wheel 602 can self-lock. At this time, the worm 606 can drive the worm wheel 602 to rotate, but the worm wheel 602 cannot drive the worm 606 to rotate, so that the clothes drying rod 1 can stay in the designated position and will not move downward due to its own gravity.
[0031] In this embodiment of the utility model, the upper end of the hanging ball 8 is a rectangular parallelepiped, and the lower end is a ring with a notch at the bottom. The top end of the clothes drying rod 1 is a cylinder that fits into the bottom end of the hanging ball 8, so that the hanging ball 8 and the clothes drying rod 1 can be detachably connected. The cylindrical part at the top of the clothes drying rod 1 is inserted into the ring with a notch at the bottom of the hanging ball 8, thus completing the assembly of the hanging ball 8 and the clothes drying rod 1. This allows the device to be adapted to different models of clothes drying rods 1, achieving a better effect of drying different items.
[0032] In this embodiment of the utility model, a plurality of equally spaced hanging holes are provided through the clothes drying rod 1 to facilitate the drying of clothes.
[0033] In this embodiment of the invention, a limiting block 5 is provided on the steel wire rope 3 at the top of the hand-cranked box 6 to prevent the clothes rack from colliding with the pulley assembly 2. When the clothes rack rises close to the pulley assembly 2, the limiting block 5 will be stuck at the top of the hand-cranked box 6, preventing the steel wire rope 3 from entering the hand-cranked box 6 and stopping the steel wire rope 3 from moving. This stops the clothes rack 1 from rising, avoids collision with the pulley assembly 2, and enhances the service life of the device.
[0034] In this embodiment of the utility model, the clothes drying rod 1 is provided with plugs 9 at both ends to prevent the clothes drying rack from scratching the user.
[0035] Working principle: After the wire rope 3 comes out of the hand-cranked box 6, it first passes through the fourth wire-passing hole on the wire-passing ball 403. The wire-passing ball 403 is fixedly connected to the rotating shaft 402, allowing the wire-passing ball 403 to rotate with the rotating shaft 402, giving the device a omnidirectional rotation function. The wire rope 3 passes through the first wire-passing hole, then through the second wire-passing hole at the top of the pulley bracket 202, pressing against the pulley. Then it passes through the second wire-passing hole at the bottom of the pulley bracket 202, and finally exits through the third wire-passing hole in the center of the top cover 203, and is then connected to the hanging ball 8. When the wire rope 3 moves, the rotatable wire-passing ball 403 and the pulley can reduce the friction between the devices, increasing the efficiency of the movement. The service life of the wire rope 3; during use, turn the handle 7, which drives the rotating rod 603 to rotate. Then, the rotating rod 603 drives the worm 606 to rotate through the bevel gear set 605. The worm 606 then drives the worm wheel 602 to rotate. Next, the worm wheel 602 drives the winding roller 601 to rotate, so that the wire rope 3 is wound on the winding roller 601 or unwound from the winding roller 601, thus completing the height adjustment of the clothes drying rod 1. The lead angle of the worm 606 is less than the equivalent friction angle between the gears. At this time, the worm 606 can drive the worm wheel 602 to rotate, but the worm wheel 602 cannot drive the worm 606 to rotate, so that the clothes drying rod 1 can stay in the designated position and will not move downward due to its own weight.
