Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a lower beam track structure of a soft yarn curtain. Background Art

[0002] The lower beam track structure of the traditional soft gauze curtain is composed of a rotating shaft for cooperating with the bottom of the soft gauze curtain and side guards arranged on both sides of the rotating shaft. The two ends of the rotating shaft are rotatably connected to the two side guards respectively, and a connecting plate is connected between the bottoms of the two side guards. A limiting groove is formed between the connecting plate and the rotating shaft to prevent the curtain fabric of the soft gauze curtain from slipping off the rotating shaft or the rotating shaft from excessively moving upward and slipping off the curtain fabric. One end of the curtain fabric of the traditional soft gauze curtain is connected and cooperated with the winding device in the top beam, and the other end extends to the rotating shaft and cooperates with the winding device in the top beam after bypassing the rotating shaft, and the natural drooping of the curtain fabric is achieved by relying on the deadweight of the rotating shaft. If the rotating shaft of the traditional soft gauze curtain is unbalanced during the winding process, the deviation of the soft gauze curtain will occur, resulting in the curtain fabric being skewed, that is, the curtain fabric has a height difference phenomenon. In the prior art, it is necessary to remove the entire curtain or frequently pull the curtain rope to adjust the curtain posture to adjust the imbalance state of the curtain. At the same time, the traditional rotating shaft is exposed to the outside world and affects the appearance. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model provides a lower beam track structure of a soft gauze curtain, including a lower beam, wherein the lower beam is penetrated with a receiving groove for accommodating the bottom of the external soft gauze curtain along its length direction, and the top wall of the lower beam is provided with a through groove along its length direction for the bottom of the external soft gauze curtain to penetrate into the receiving groove, the through groove is connected to the receiving groove, a rotating shaft for cooperating with the bottom of the external soft gauze curtain is rotatably arranged in the receiving groove, the diameter of the rotating shaft is larger than the width of the through groove, and a balancing member for adjusting the balance of the lower beam is arranged on the bottom wall of the lower beam.

[0005] The advantages of adopting the above technical solution are as follows: the rotating shaft is rotatably arranged in the receiving groove and the rotating shaft cooperates with the bottom of the soft gauze curtain. During assembly, the bottom of the soft gauze curtain is placed in the receiving groove through the through groove and then the rotating shaft is inserted into the receiving groove and into the bottom of the soft gauze curtain. At this time, one end of the soft gauze curtain curtain is connected to the winding device in the external curtain top beam, and the other end is placed in the receiving groove and passes through the rotating shaft and then passes through the receiving groove and is connected to the winding device in the top beam. At this time, the outer peripheral wall of the rotating shaft is arranged in contact with the inner peripheral wall of the bottom of the soft gauze curtain curtain. Affected by the deadweight of the lower beam and the length of the curtain, the rotating shaft moves relative to the through groove. At this time, the outer peripheral wall of the rotating shaft abuts and cooperates with the inner peripheral wall of the bottom of the curtain cloth, and the peripheral wall of the bottom of the curtain cloth abuts and cooperates with the inner walls on both sides of the through groove, that is, the rotating shaft and the through groove are respectively abutted and cooperated. The inner wall combination of the groove forms a clamping limit for the curtain, and the diameter of the rotating shaft is larger than the width of the groove, so that the rotating shaft cannot escape from the groove, thereby realizing the stable placement of the bottom of the curtain curtain in the groove; in the above technology, the rotating shaft is located in the groove, so that the rotating shaft is not exposed to the outside world, thereby improving the aesthetics, and at the same time reducing the impact of external stress or the collision of the rotating shaft with the external wall to cause the rotating shaft to break or be damaged, thereby avoiding the rotating shaft from breaking or being damaged and causing the curtain curtain to be unbalanced or operating failure; the setting of the balance member in the above technology makes it easy for the user to manually adjust the weight of the lower beam when the curtain is unbalanced on one side or there is a height difference, so that when the curtain is pulled, the balance member can increase the weight of the unbalanced side of the curtain, thereby achieving the purpose of quickly adjusting the balance of the lower beam.

[0006] The utility model further arranges that: the inner walls on both sides of the through groove are respectively connected to the inner peripheral wall of the containing groove in a smooth arc surface and are formed with a rib, and the distance between the two ribs is smaller than the diameter of the rotating shaft.

[0007] The benefits of adopting the above technical solution are: the setting of the retaining edge is used to cooperate with the rotating shaft to improve the clamping force and limiting force of the curtain drape, and at the same time the distance between the two retaining edges is smaller than the diameter of the rotating shaft, further preventing the rotating shaft from escaping from the groove through the groove, thereby improving the stability of the rotating shaft in the groove.

[0008] The utility model is further configured as follows: the lower beam is provided with an adjustment groove along its length direction, the balance member includes a gravity block slidably arranged in the adjustment groove, the bottom wall of the lower beam is provided with a slide groove connected to the adjustment groove along its length direction, the radial cross-section of the gravity block is adapted to the radial cross-section of the adjustment groove, and the width of the gravity block is larger than the width of the slide groove.

[0009] The benefits of adopting the above technical solution are: when it is necessary to adjust the balance of the lower beam, the gravity block can be moved through the slide groove. The change in the position of the gravity block in the adjustment groove will change the balance of the lower beam, so that gravity adjustment can be performed on the imbalance of the curtain cloth, thereby keeping the lower beam in a relatively balanced state. The entire adjustment process is fast and efficient, thereby improving the adjustment efficiency. In the above technology, the width of the gravity block is larger than the width of the slide groove, so as to prevent the gravity block from escaping from the adjustment groove along the direction in which the slide groove is opened.
