Abstract
Description
Technical Field
[0001] The invention relates to a drying device, in particular to a firmly positioned lifting type drying rod, belonging to the technical field of daily hardware products. Background Art
[0002] At present, the lifting drying racks on the market generally use steel wire ropes to hang the drying racks, and then use motors or manual cranks to control the winding reel to reel in and out the steel wire ropes, thereby controlling the lifting and lowering of the drying racks. Such drying racks are often large in size, and when the clothes are hung and raised for drying, they are still only hung by steel wire ropes, and cannot be firmly positioned. Once there is wind, the drying racks will sway around with the clothes being dried, posing certain safety hazards. If the drying rack's hanging rod is a bare rod, it will also cause the clothes to shift and pile up, resulting in poor drying effect due to insufficient air permeability between adjacent clothes. In order to reduce the swinging of the drying rack by the wind, the size and weight of this type of drying rack need to be increased, the hanging rods for drying clothes and drying quilts need to be separated, and a four-point lifting method is used. However, when there is a strong wind, it is still impossible to completely avoid the shaking and swinging of the drying rack. Moreover, when this type of drying rack reels and reels the wire rope through a winding reel, the wire rope is easily misplaced in the winding reel due to its small body, resulting in the drying rack being raised and lowered not smoothly, and sometimes the lifting and lowering may be stuck.
[0003] In addition, some lifting drying racks on the market use scissor brackets to hang the drying racks, but the scissor brackets have poor performance in coping with lateral shear forces. When the clothes are hung and the wind blows, the scissor brackets will cause great lateral shear forces, which may easily cause the scissor brackets to be damaged and unable to implement lifting control. Summary of the invention
[0004] The purpose of the present invention is to provide a firmly positioned lifting type clothes-drying rod, which is only provided with one main clothes-drying rod. After being raised to the right position, it can automatically and firmly lock the position without swinging around or failing to be lifted due to wind.

The middle part of the swing arm 25 is hinged on the hinge shaft extending from the outer wall of the lock tongue slot 22, and the front end of the swing arm 25 extends to a position close to the front cover plate of the lock box 20. A limit nail 20.2 for limiting the downward swing limit of the front end of the swing arm 25 is provided on the rear edge of the side opening of the lock box 20 at the lower side of the front end arm body of the swing arm 25. There is a hook head 25.1 that bends toward the lock tongue 23 and matches the positioning groove 23.2 of the lock tongue 23. A swing arm tension spring 26 is provided between the rear end arm body of the swing arm 25 and the rear cover plate of the lock box 20 to make the rear end of the swing arm 25 swing upward; the lock tongues 23 of the left and right main rod lockers 6 are also respectively tied with pull ropes 27 extending backward on the hanging nails 23.1. After the two pull ropes 27 are guided by a plurality of pull rope guide wheels 28 at corresponding positions, they are connected downward to the unlocking handle 19 of the driving assembly and form a backward swing pull on the unlocking handle 19; when the main rod locker 6 is in the locked state, the lock tongue 23 moves forward to the front end of the lock tongue 23 under the pull of the lock tongue tension spring 24, extends into the lock box 20 and is placed on the lock tongue support edge 20.1, and at the same time, the forward-moving lock tongue 23 pulls the unlocking handle 1 through the pull rope 27 9 swings backward to trigger the position switch 18 to operate; when the main rod lock 6 is in the unlocked state, the lock tongue 23 overcomes the pulling of the lock tongue spring 24 and moves backward to the position where the front end of the lock tongue 23 exits the lock box 20 and the positioning groove 23.2 of the lock tongue 23 matches the hook head 25.1 at the rear end of the swing arm 25, and the front end arm body of the swing arm 25 abuts against the limit pin 20.2 under the pulling of the swing arm tension spring 26, and the hook head 25.1 at the rear end of the swing arm 25 is stuck in the positioning groove 23.2 of the lock tongue 23 to limit the forward movement of the lock tongue 23; when the main hanging rod 7 rises to the main rod lock 6, the end of the main hanging rod 7 enters the lock box 20 from the lower opening and the side opening of the lock box 20, and the rod body of the main hanging rod 7 pushes the front end arm body of the swing arm 25 to swing so that the hook head 25.1 at the rear end of the swing arm 25.1 is separated from the positioning groove 23.2 of the lock tongue 23, and the main rod locker 6 is converted from the unlocked state to the locked state. The front end of the lock tongue 23 extends into the lock box 20 and is supported below the end of the main hanging rod 7. The main rod lockers 6 at the left and right ends lock and fix the two ends of the raised main hanging rod 7.
[0034] Further, the driving assembly is also fixedly connected to the lower rotating shaft 10 with a large bevel gear 29 that rotates synchronously with the lower rotating shaft 10, and the lower mounting frame is provided with a small bevel gear 30 that can rotate in situ and mesh with the large bevel gear 29 beside the large bevel gear 29, the spindle of the small bevel gear 30 is installed on the corresponding bearing and is provided with a clamping end 30.1 exposed outward, and a hand crank wrench 31 that can be taken out and used to clamp the clamping end 30.1 of the small bevel gear 30 to drive it to rotate is hung on the side of the lower mounting frame. When the power supply has no electricity and the DC reduction motor 14 cannot be started to drive the main pole 7 to lift, the hand crank wrench 31 can be removed and clamped on the clamping end 30.1 of the small bevel gear 30, and the small bevel gear 30 is driven to rotate in situ by the hand crank wrench 31 to drive the lower rotating shaft 10 to rotate, thereby driving the main pole 7 to lift. After manual lifting is completed, the hand crank wrench 31 should be promptly disengaged from the locking end 30.1 of the small bevel gear 30 and hung back to its original position to avoid personal injury caused by the hand crank wrench 31 passively rotating with the small bevel gear 30 during subsequent operations.
[0035] Furthermore, the middle parts of the forward extension rods of the two fixed brackets 1 are connected into one body through a horizontal transverse positioning rod 32 to limit the distance between the two forward extension rods and connect the two fixed brackets 1 into a stable whole.
[0036] Furthermore, in order to prevent the end of the flat belt from slipping when it is connected to the reel, the reel 4, the upper drive reel 5, and the lower drive reel 11 are all I-shaped reels, and a fixing strip is provided on the side of the reel's spindle. The end of the flat belt is looped and hung on the fixing strip and then wound around the reel's spindle. The fixing strips of the left and right reel 4 are located at the same position beside the spindle to ensure that the reeling and releasing of the hanging flat belt 8 on the left and right sides are consistent.
[0037] Furthermore, the hanging flat belt 8 and the driving flat belt 16 are both made of canvas or nylon flat belt with a thickness of 2 mm and a width of 30 mm.
[0038] Furthermore, in order to make the forward and backward movement of the lock tongue 23 in the lock tongue slot 22 more stable, a longitudinal notch 22.1 extending forward is provided on the rear side of the upper cover plate of the lock tongue slot 22 at the position corresponding to the hanging nail 23.1 of the lock tongue 23. When the lock tongue 23 moves forward for locking, the hanging nail 23.1 of the lock tongue 23 enters the longitudinal notch 22.1 of the upper cover plate of the lock tongue slot 22.
[0039] In order to prevent the moving parts from being contaminated or causing harm to people, the driving assembly and the left and right main rod lockers 6 are provided with corresponding shells to shield and protect the moving parts, which are not drawn in the drawings.
[0040] When the lifting type drying rod is used, the fixed bracket 1 is installed at a high position on the wall, the front extension rod of the fixed bracket 1 is about 2.5 meters above the ground, and the driving assembly is about 1.3 meters above the ground. The main drying rod 7 is initially in a raised state and the two ends of the main drying rod 7 are locked in the main rod lockers 6 on the left and right sides. 2, and the hook 25.1 at the rear end of the swing arm 25 is stuck in the positioning groove 23.2 of the lock tongue 23 to limit the forward movement of the lock tongue 23, thereby limiting the main rod lock 6 in the unlocked state. After the main rod locker 6 is unlocked, the main hanging rod 7 pulls the hanging flat belt 8 to automatically lower under the action of gravity, so that the main hanging rod 7 falls smoothly until the hanging flat belt 8 in the reel 4 is lowered to the end. While the hanging flat belt 8 is lowered, the upper driving reel 5 will reel the driving flat belt 16 from the lower driving reel 11 and drive the lower shaft 10 to rotate, but the driven gear 12 does not rotate with the lower shaft 10 under the action of the one-way clutch mechanism. When the main pole 7 is to be raised, the motor switch 17 is turned on to energize the DC reduction motor 14, and the DC reduction motor 14 drives the lower shaft 10 to rotate via the driving gear 13 and the driven gear 12, and the lower driving reel 11 retracts the driving flat belt 16 from the upper driving reel 5 and drives the reel-up shaft 3 to rotate, so that the reel-up reel 4 reels the hanging flat belt 8 to lift the main pole 7. When the main pole 7 rises to the main pole locker 6, the end of the main pole 7 enters the lock box 20 from the lower opening and the side opening of the lock box 20, and the drying main pole 7 is lifted. The rod body of the hanging main rod 7 pushes the front end of the swing arm 25 to swing so that the hook head 25.1 at the rear end of the swing arm 25 is separated from the positioning groove 23.2 of the lock tongue 23, and the main rod locker 6 is converted from the unlocked state to the locked state. The front end of the lock tongue 23 extends into the lock box 20 and is supported under the end of the main hanging rod 7 to form a lock. After the lock tongue 23 moves forward, it will pull the unlocking handle 19 to swing backward through the pull rope 27, so that the unlocking handle 19 triggers the normally closed contact of the position switch 18 to disconnect, and the DC reduction motor 14 automatically cuts off the power to stop lifting the main hanging rod 7. After the main hanging rod 7 is raised, the motor switch 17 needs to be turned off.
[0041] In order to enable the main hanging rod 7 to use the same rod body to meet different drying needs, that is, when using a clothes hanger to dry clothes, a limit piece can be set on the rod body of the main hanging rod 7 to limit the clothes hanger from sliding on the main hanging rod 7, thereby avoiding the phenomenon that multiple pieces of clothing are piled up together due to wind and affect the drying effect; when drying large fabrics such as quilts, the main hanging rod 7 can retract the limit piece on the rod body to avoid scratching the quilt. The main hanging rod 7 adopts a variable limit type hanging main rod 7.
