Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a back regulator for a middle or low pole. Background Art

[0002] Curtains have the functions of sunshade, heat insulation, indoor light regulation, and interior decoration, including roller blinds, venetian blinds, honeycomb blinds, Roman blinds, etc. Crossbars (or medium and low poles) are often used in curtains, especially foldable curtains, which set the fabric in layers through crossbars (or medium and low poles). For example, the foldable Roman blinds with the authorization publication number CN204033028U have drawstrings fixed to the crossbars by knotting, and the knots are completely exposed, which is very unsightly. Moreover, when adjusting the tightness of the drawstrings, it is necessary to manually adjust the length of the drawstrings by repeatedly tying knots, which is cumbersome to operate and wastes manpower. The applicant previously applied for a curtain drawstring crossbar adjuster with application number 2024211675090, but it needs to be used in conjunction with the buckle set on the crossbar, and it is not beautiful to be exposed outside the crossbar. At the same time, the medium and low poles have certain requirements for load-bearing capacity, and it is difficult for the current adjuster to meet the requirements. Utility Model Content

The adjuster is suitable for adjusting the back of medium and low poles. The pull rope is pulled by rotating the reel to adjust the tightness of the pull rope and adjust the medium and low poles to a horizontal state. At the same time, the adjuster does not need to be used in conjunction with other devices, and is easy to operate. There is no need for manual repeated knotting and adjustment, which saves manpower.

[0004] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0005] The back adjuster of the mid-low pole includes several groups of adjustment units slidably arranged in the cavity of the mid-low pole. Each adjustment unit includes a first connecting part, a second connecting part detachably connected to the first connecting part, and a reel arranged between the two. The first connecting part and the second connecting part cooperate to install the reel. A wire hole is provided in the reel. The pull rope passes through the wire hole and the tightness of the pull rope can be adjusted by rotating the reel.

[0006] Preferably, the reel includes a winding rod, a nut head located on one side of the winding rod and an end plate located on the other side of the winding rod, and the wire hole is provided on the winding rod; a first through hole is provided on the first connecting member, and a second through hole opposite to the first through hole is provided on the middle and lower rods, and the nut head extends into the first through hole or passes through the second through hole to drive the reel to rotate through the nut head to adjust the tightness of the pull rope.

[0007] Preferably, a first latching tooth is provided on the nut head facing the first connecting member, and a second latching tooth matching the first latching tooth is provided on the side of the first connecting member facing the reel.

[0008] Preferably, the first latching teeth are distributed in a ring shape along the nut head, and the second latching teeth are distributed in a ring shape along the outer periphery of the first through hole. The first latching teeth and the second latching teeth engage with each other to achieve multi-point winding of the draw rope.

[0009] Preferably, the nut head is provided with a slot, which is a slotted groove, a cross slot, a prismatic slot or a plum blossom slot, so as to cooperate with the slotted lifter, the cross lifter, the prismatic lifter or the plum blossom lifter to drive the reel to rotate.

[0010] Preferably, an insertion rod is provided on the end plate, a third through hole is provided on the second connecting member, and the insertion rod is plugged into the third through hole to limit the reel.

[0011] Preferably, a spring is sleeved on the insertion rod, and two ends of the spring respectively abut against the second connecting member and the end plate to limit the reel.

[0012] Preferably, the first connecting member is provided with a buckle, and the second connecting member is provided with a slot, so as to enable the first connecting member and the second connecting member to be quickly connected and fixed to the cable reel.

[0013] Preferably, the buckles are provided in at least two groups, and the buckling directions of the two groups of buckles are opposite.

[0014] Preferably, a card cap is inserted into the second through hole to cover the second through hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The adjuster of the utility model is suitable for back adjustment of medium and low poles. The reel is quickly installed by cooperating with the first connecting piece and the second connecting piece. The reel is rotated to pull the draw rope to adjust the tightness of the draw rope and adjust the medium and low poles to a horizontal state. At the same time, the adjuster does not need to be used in conjunction with other devices, and is easy to operate. There is no need for manual repeated knotting and adjustment, which saves manpower.

[0017] At the same time, multiple sets of adjusters can be set in the middle and low poles according to their load-bearing requirements. There is no limit on the number of adjusters hidden in the middle and low poles, which is more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS
