Fig. 1 and 5 show a schematic construction of a dual pole assembly for facilitating relative distance adjustment, wherein fig. 1 shows no telescoping pole or telescoping pole retracted condition and fig. 5 shows telescoping pole extended condition. To achieve the above object, two designs are dependent: the self-locking mechanism 4 is a device capable of locking the flexible connecting piece 3-1 with a pulling trend in a one-way and unlocking the flexible connecting piece 3-1 with a retracting trend reversely, and the self-locking mechanism 4 is an elastic pulling piece 3-3 used for enabling the flexible connecting piece 3-1 to be pulled out or retracted in a corresponding airing rod, and the pulling force of the dead weight of the lower airing rod 2 on the corresponding side flexible connecting piece 3-1 is required to be larger than the pulling force of the corresponding elastic pulling piece 3-3 on the flexible connecting piece 3-1. As described with reference to fig. 1 and 5, the pull force of the dead weight G of the lower airing rod 2 acting on the flexible connecting pieces 3-1 at two sides is G/2, the elastic pull-up piece 3-3 has a pull force F on the flexible connecting pieces 3-1, and the lower airing rod 2 always has a downward moving trend because the pull force F is smaller than the pull force G/2, and the locking resistance of the self-locking mechanism 4 on the flexible connecting pieces 3-1 and the sum of the pull force of the elastic pull-up piece 3-3 on the flexible connecting pieces 3-1 are balanced with the pull force of the dead weight of the lower airing rod 2 acting on the flexible connecting pieces 3-1 because the self-locking mechanism 4 has a unidirectional locking effect on the flexible connecting pieces 3-1 with a pull-out trend, so that the lower airing rod 2 can hover below the upper airing rod 1. When the self-locking mechanism 4 is unlocked, the locking resistance of the self-locking mechanism 4 to the flexible connecting piece 3-1 is reduced or eliminated, so that the lower airing rod 2 can automatically move downwards under the action of gravity, and the downward moving distance of the lower airing rod 2 can be controlled by controlling the unlocking state of the self-locking mechanism 4, so that the adjustment of the relative distance between the upper airing rod and the lower airing rod is realized. When the lower airing rod 2 is retracted, the lower airing rod 2 is lifted upwards, so that the pulling force of the lower airing rod 2 acting on the flexible connecting piece 3-1 is reduced, when the pulling force is smaller than the pulling force F of the elastic retracting piece 3-3 on the flexible connecting piece 3-1, the flexible connecting piece 3-1 with the retracting trend is automatically unlocked due to the self-locking mechanism 4, at the moment, the elastic retracting piece 3-3 automatically pulls the flexible connecting piece 3-1 to retract, the lower airing rod 2 can be retracted upwards, and after the lifting action is stopped, the lower airing rod 2 is kept at a required position under the self-locking action of the self-locking mechanism 4. Through adjusting the relationship between the dead weight of the lower airing rod 2 and the tension value of the elastic pull-out piece 3-3, the lower airing rod 2 can be moved upwards by small lifting force, and the lifting and retracting operation of the lower airing rod 2 is easy and labor-saving.

Fig. 3 and 6 show the interaction between the self-locking mechanism 4, the elastic pullout 3-3 and the lower drying pole 2. The elastic drawing-back piece 3-3 is responsible for automatically retracting the flexible connecting piece 3-1, and the self-locking mechanism 4 is used for realizing the adjustment of the drawing-out length of the flexible connecting piece 3-1 and ensuring the hovering effect of the lower airing rod 2 under the dead weight. Therefore, the lower airing rod 2 does not need to be pulled by hands to hang clothes like the prior art, so that the lower airing rod 2 is more flexible and convenient to use. And because the adjustable range of the distance between the upper airing rod 1 and the lower airing rod 2 is large, enough space can still be kept for hanging clothes on the upper airing rod 1 when the lower airing rod 2 is used, and the utilization rate of the upper airing rod and the lower airing rod is improved.

Fig. 2 and 4 and fig. 7 to 9 show a specific construction of the self-locking mechanism 4. The self-locking mechanism 4 is internally provided with a one-way locker 4-1, the flexible connecting piece 3-1 is a steel wire rope, the flexible connecting piece 3-1 penetrates through the one-way locker 4-1, the flexible connecting piece 3-1 with a pulling trend is locked in a one-way by the one-way locker 4-1, the flexible connecting piece 3-1 with a retracting trend is unlocked in a reverse way, and the unlocking piece 4-2 acts on the one-way locker 4-1 and is used for unlocking the one-way locking state of the one-way locker 4-1. The unidirectional locker 4-1 is a steel wire rope locker, the structure is simple and compact, the unidirectional locker 4-1 is stable in unidirectional locking and reverse unlocking actions of the steel wire rope, and can bear larger pulling force after locking, so that the whole airing load of the lower airing rod is ensured.

Fig. 10 shows a laundry rack with the dual pole assembly described above. The clothes hanger comprises the main machine 5, the lifting connecting piece and the double-airing-rod assembly convenient for relative distance adjustment, wherein the main machine 5 is connected with the upper airing rod 1 through the lifting connecting piece 6, so that the practicability and the user experience of the clothes hanger with the upper airing rod and the lower airing rod are greatly improved, and the market competitiveness is improved.
