Description

Technical Field

[0001] The utility model relates to a Shangri-la curtain, in particular to a bottom rod adjustable connecting device of the Shangri-la curtain, belonging to the technical field of curtains. Background Art

[0002] Shangri-La curtain is a brand-new design that combines electric curtain, window screen, blinds and roller blinds. The curtain body of Shangri-La curtain mainly includes two layers of light-transmitting veils, and a number of light-blocking strips are arranged between the two layers of light-transmitting veils. By adjusting the veil on one side up and down, the light-blocking strip is in a horizontal, oblique or vertical state. When the two layers of light-transmitting veils are adjusted to the maximum spacing state, the light-blocking strip is in a horizontal state or nearly horizontal state, and light can penetrate the light-transmitting veil and shine into the room from the gap between the light-blocking strips. At this time, the amount of light entering is the largest. When the two layers of light-transmitting veils are adjusted to a fitting state or a nearly fitting state, the light-blocking strip is in a vertical state or a nearly vertical state, and each light-blocking strip can block light from shining into the room.

[0003] In order to allow the light-transmitting veil of the curtain body to be adjusted up and down smoothly, a counterweight structure is set at the bottom of the curtain body. The traditional counterweight structure usually uses a base plate, and the bottoms of the front and rear layers of light-transmitting veils are connected to the two sides of the base plate. The disadvantage of this structure is that due to the limitation of the base plate structure, when the light-transmitting veil on one side is pulled up, the light-blocking strip cannot be completely vertical, resulting in a poor closure of the light-blocking strip, and light can still shine into the room through the gap that is not completely closed. Therefore, people invented a method of connecting a bottom rod to the bottom of the two layers of light-transmitting veils, and using the two bottom rods to counterweight the front and rear layers of light-transmitting veils. However, when the wind blows the curtain body, the two bottom rods are prone to collision, which will cause noise and affect the service life. Therefore, some people designed a connection structure between the two bottom rods, such as Chinese utility model patent 202321079136.7, the patent name is "A Shangri-La curtain bottom rod sealing anti-collision device", which includes a spacer with a length, and both ends of the spacer are rotatably connected to a connecting member, and the two connecting members are respectively connected to the bottom rod. Through the pivotal setting of the connecting member and the spacer, the purpose of preventing the collision of the two bottom rods can be achieved. However, the common Shangri-La curtain bodies on the market currently have two sizes of 6cm and 7.5cm (the spacing between the front and rear layers of light-transmitting veils is 6cm and 7.5cm), and the connecting members and spacers of this structure cannot be adjusted accordingly according to different curtain body sizes, and its versatility is poor. Developing corresponding sizes of connecting members and spacers according to curtain bodies of different sizes leads to increased production costs. Summary of the invention

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a bottom rod adjustable connection device for Shangri-la curtains which can be adjusted according to the size of the curtain body, has convenient adjustment, good versatility, simple structure and reduces production costs.

[0005] The utility model discloses a technical scheme of a bottom rod adjustable connection device of a Shangri-la curtain: comprising a first bottom rod and a second bottom rod, wherein the first bottom rod is provided with first end covers at both ends, the second bottom rod is provided with second end covers at both ends, the outer wall of the first end cover is provided with a first adjusting piece, one side of the first adjusting piece is rotatably connected to the first end cover, more than two adjusting holes are formed in the first adjusting piece, the outer wall of the second end cover is provided with a second adjusting piece, one side of the second adjusting piece is rotatably connected to the second end cover, more than one adjusting pin is formed on one side of the second adjusting piece, and the adjusting pin matches the adjusting hole.

[0006] Furthermore, there are three adjustment holes and two adjustment pins.

[0007] Furthermore, a first opening groove is formed in the adjusting pin, and a first convex ring is formed on the head of the adjusting pin, and the first convex ring matches with the adjusting hole.

[0008] Furthermore, the first end cover and the second end cover are respectively provided with through holes, and a turn pin is respectively provided on one side of the first adjustment plate and the second adjustment plate, and a second opening groove is provided in the turn pin, and a second convex ring is provided on the head of the turn pin, the turn pin is inserted into the through hole, and the second convex ring cooperates with the through hole.

[0009] Furthermore, the second adjusting piece is provided with a limiting groove on one side of the adjusting pin, and the limiting groove cooperates with the first adjusting piece.

[0010] The utility model provides a bottom rod adjustment connection device for a Shangri-La curtain with the following beneficial effects: the second adjustment piece is inserted into the adjustment hole of the first adjustment piece through the adjustment pin on one side, so that the first bottom rod and the second bottom rod are connected to each other and have a limiting effect. When the wind blows the curtain body, the first bottom rod and the second bottom rod can be prevented from colliding. When curtain bodies of different widths are selected, the adjustment pin of the second adjustment piece can be removed from the adjustment hole of the first adjustment piece, and the adjustment pin can be inserted into the corresponding adjustment hole. People can adjust the first adjustment piece and the second adjustment piece accordingly according to the different widths of the curtain body.
