There are two symmetrically arranged positioning plates and two roller guide rods arranged up and down dislocation, the positioning plates are arranged between the two rollers, and the two roller guide rods are respectively tangent to the outer edges of the upper and lower rollers.

Preferably, the sound insulation blades located at the left and right ends are provided with roller structures respectively at the upper and lower ends.

Preferably, the sound insulation blades are respectively provided with roller structures on the side edges located on the track side after being folded.

Preferably, the curtain frame is tightly fixed to the inner wall through a steel frame.

The beneficial effects of the present utility model:

By arranging folding curtains, curtain panels and sound-absorbing cotton, the utility model can realize the heat insulation and sound insulation of the curtains, facilitate the opening and closing of the curtains, and can achieve good heat insulation and sound insulation effects.

The sound insulation blade of the rigid multi-layer structure of the utility model has better sound insulation effect; the concave-convex sealing structure between the sound insulation blades can satisfy the closing and opening of the curtain, and after the closing, the sealing effect is high, and it has a good sound insulation effect. Sound insulation.

By being arranged indoors and around the window opening, the utility model is convenient to operate and easy to install, does not affect the existing window structure, and can be disassembled as a whole.

By arranging sound-absorbing cotton along the curtain frame, the utility model matches the structure of the folding curtain panel assembly, does not affect the opening and closing of the folding curtain panel assembly, and can realize the sealing of the folding curtain panel assembly and the window hole after the curtain is closed, thereby realizing the sound insulation of the curtain. .

Detailed ways

In order to make the objectives, technical solutions and beneficial effects of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of the skilled person.

As shown in Figures 1-6, the built-in sound insulation curtain structure includes a curtain frame 1, a folding curtain panel assembly 2, and a sound-absorbing cotton 3 arranged along the curtain frame. The curtain frame 1 is arranged indoors and around the window hole, and the curtain frame 1 is tightly fixed to the inner wall around the window hole through a steel frame. The folding curtain panel assembly 2 includes a sound-insulating blade 5 of a rigid multi-layer structure, a hinge cross hinge 6 connecting the sound-insulating blades and a roller structure; the opposite surfaces of each adjacent two sound-insulating blades 5 are mutually matched concave-convex sealing structures ( As shown in Figure 4); the roller structure is arranged on the upper and lower end surfaces of the sound insulation blade 5, and the roller structure is connected with the sound insulation blade 5; the upper and lower ends of the window hole located in the room are respectively provided with a track 4 that matches the roller structure.

The roller structure includes two rollers 7 and a rotating shaft 8, and the two rollers 7 are connected to the rotating shaft 8, one up and one down. The roller structure is arranged on the upper and lower end surfaces of the folding curtain panel assembly 2 , and the roller structure is axially connected with the folding curtain panel assembly 2 through the rotating shaft 8 . The track 4 is matched with the roller structure, the cross section of the track 4 is a box structure with a shaft channel 9 at the lower end, and the track 4 is provided with two symmetrical positioning plates 10 and two roller guide rods 11 arranged up and down dislocation, The positioning plate 10 is arranged between the two rollers 7 , and the two roller guide rods 11 are respectively tangent to the outer edges of the upper and lower rollers 7 .
