Description

Technical Field

[0001] The invention relates to a drying device, in particular to an improved variable limit-type drying rod, belonging to the technical field of daily hardware products. Background Art

[0002] The applicant's prior Chinese patent CN202321215162.8 discloses a variable limit type air-drying rod, in which a separation nail assembly and a control shaft assembly are sleeved in the tube body of the air-drying main rod; the guide column of the separation nail assembly slides into the guide sleeve of the air-drying main rod, and the separation nail corresponds to the perforation on the air-drying main rod; the control shaft assembly is provided with a control shaft and an eccentric cam, and sealing plates are provided on both sides of the air-drying main rod to support the control shaft, and the bottom surface of the separation nail mounting plate elastically rests on the eccentric cam; the control shaft is connected to a control wheel, and the control shaft and the eccentric cam are driven to rotate by rotating the control wheel, thereby controlling the separation nail to extend outward or retract from the air-drying main rod tube body. When drying clothes, the separation nail can be controlled to extend outward from the air-drying main rod tube body to limit the sliding of the hanger and prevent the clothes from piling up; when drying quilts, the separation nail can be controlled to be retracted into the air-drying main rod tube body to prevent the separation nail from scratching the quilt, so that the air-drying rod can use the same air-drying rod to meet different drying needs.

[0003] The applicant has found through repeated experiments that the product made according to this technical solution still has certain defects in actual use, which are mainly reflected in: (1) The hanging rod is only provided with push springs at the left and right ends of the main hanging rod to control the downward movement of the partition nail assembly. Since the partition nail assembly is a long horizontal strip, the length of which is generally more than 1.5m, the synchronization effect is not ideal if the push springs at both ends are used to push the entire partition nail assembly downward. It is easy for only the partition nails at the two ends to move downward while the partition nails in the middle are still lifted up, resulting in control failure.

[0004] (2) The control shaft of the hanging rod can only rotate in place under the rotation support of the left and right sealing plates and cannot move up and down. When the rotating operating wheel drives the control shaft and the eccentric cam to rotate, the eccentric cam sometimes gets stuck on the side of the partition nail mounting plate and cannot pass through, causing it to get stuck. In addition, due to the limited inner diameter of the main hanging rod, the eccentric cam driven by the control shaft rotating in place can only control the partition nail assembly to float up and down within a smaller range. Therefore, the length that the partition nail can extend is short, and the limit on the sliding of the hanger is not good enough.

[0005] (3) The clothes-drying and hanging rod lacks a limit stop for the specific rotation position of the control shaft. When the rotating control wheel drives the control shaft and the eccentric cam to rotate and move the separation nail assembly upward, it is difficult to control the separation nail to stay at the maximum extension position. Summary of the invention

[0006] The purpose of the present invention is to provide an improved variable limit type clothes-drying rod, which improves the above-mentioned defects of the prior technical solution of the applicant and adds some design structures to obtain a variable limit type clothes-drying rod with better use effect.

[0007] The specific technical solutions adopted by the present invention are as follows: An improved variable limit type hanging rod, which is provided with a horizontally arranged round tube as the main hanging rod, and the top of the outer tube wall of the main hanging rod is provided with multiple pairs of evenly spaced through holes, and each pair of through holes is provided with two hole positions separated on the left and right; a separation nail assembly and a control shaft assembly are mounted inside the tube body of the main hanging rod; the separation nail assembly is provided with a horizontally transverse separation nail mounting strip completely placed in the tube body of the main hanging rod, and the longitudinal section of the separation nail mounting strip is an arc-shaped bent plate matching the inner tube wall of the main hanging rod, and the separation nail mounting strip is fixedly connected along the arc top of the top surface with multiple pairs of separation nails extending vertically upward and evenly spaced, and each pair of separation nails is provided with two nail columns separated on the left and right; each pair of separation nails on the separation nail mounting strip slides upward and penetrates into the main hanging rod in a one-to-one correspondence. In each pair of through holes at the top, a push spring is also provided on the outer side of each dividing nail between the top surface of the dividing nail mounting strip and the inner tube wall of the main hanging rod; a left end seat is fixedly connected to the left port of the main hanging rod, and the left end seat is a round pancake-shaped end seat with a downward door-shaped notch, and the right end face of the left end seat is provided with a limiting boss on the rear side of the notch; a detachable right end seat is fixedly connected to the right port of the main hanging rod, and the right end seat is a round pancake-shaped end seat with a downward door-shaped notch, and a locking screw is provided between the right end seat and the main hanging rod for locking; the control shaft assembly is provided with a horizontally transverse round bar-shaped control shaft, and the control shaft is provided with a radially extending limit baffle near the left end head, and the left end head of the control shaft can be movably extended into the left end seat. The control shaft is provided with a limit clamping head for limiting the right movement of the control shaft on the left side of the corresponding right end seat, and a plurality of cams distributed at intervals are fixedly connected to the shaft body under the corresponding separation nail mounting strip, and the cams are elliptical on the periphery of the control shaft; the control shaft can rotate and move up and down within the limited range of the door-shaped notch of the left end seat and the right end seat; under the action of the push spring, the lower arc surface of the separation nail mounting strip always elastically presses against the outer edge of the cam of the control shaft, so that the separation nails on the separation nail mounting strip move up and down following the rotation and up and down movement of the control shaft Movement; when the control shaft rotates clockwise from right to left until the two ends of the elliptical major axis of the cam respectively abut against the top of the arc surface of the lower arc of the partition nail mounting strip and the bottom of the inner tube wall of the hanging main rod, the limit baffle of the control shaft just abuts against the limit boss of the left end seat, thereby limiting the maximum clockwise rotation angle of the control shaft. At this time, the length of the partition nail extending out of the hanging main rod is the longest; when the control shaft rotates counterclockwise 90° from the maximum clockwise rotation angle, the control shaft will move downward as a whole so that the two ends of the elliptical major axis of the cam are placed on the inner tube wall of the lower part of the hanging main rod, and the elliptical minor axis end of the cam abuts against the lower arc surface of the partition nail mounting strip. At this time, the partition nail is retracted into the hanging main rod and the upper end of the partition nail is still inserted into the through hole of the hanging main rod.

[0008] In order to be able to stretch out the quilt when drying it, a group of U-shaped widened support frames with horizontal outward extensions and downward bent ends are fixedly connected to the front and rear sides of the outer tube wall of the main hanging rod. Each widened support frame is located at the interval between every two pairs of perforations to avoid position interference with the widened support frame when the clothes hanger is hung in the gap between each pair of separation nails.

[0009] The present hanging rod is a variable position-limited hanging rod with better use effect obtained by improving the defects of the prior technical solutions and adding some design structures. The hanging rod is equipped with a push spring for each dividing nail, so that the downward movement of the entire dividing nail assembly can be synchronized, and the phenomenon that the dividing nails at both ends move downward while the dividing nails in the middle are still lifted will not occur; by changing the support mode of the control shaft and the shape of the cam, the control shaft can also move up and down within a certain range when rotating, and it is not easy to cause the cam to be stuck by the side of the dividing nail installation strip, and the dividing nail assembly can be controlled to float up and down within a larger range in the main hanging rod with a limited inner diameter, so that the extending length of the dividing nail is longer and the sliding of the clothes hanger is better limited; by limiting the maximum rotation angle of the control shaft, the extending length of the dividing nail is the longest, and the extending state of the dividing nail can be better locked; by setting a widened support frame, the quilt can be effectively opened when drying the quilt, and the air permeability of the inner side of the quilt is increased to obtain a better drying effect.
