Compressed type shading curtain winding device of internal sealing tube
The invention discloses a compressed type shading curtain winding device of an internal sealing tube. The compressed type shading curtain winding device includes core iron, an inner tube, a spring bead and a torsion spring, wherein the inner tube is used for winding the shading curtain, and the spring bead and the torsion spring are accommodated in one end of the inner tube. A center hole coaxial with the core iron is preserved in the spring bead. The spring bead is formed by clamping a male spring bead and a female spring bead. One end of the core iron is connected with an internal sealing cover, and the other end of the core iron is connected with a fixing block of the core iron. A compressed spring is sleeved on the core iron and is accommodated in the center hole preserved in the spring bead. At least two clamping tenons are arranged on the core iron. Compression through the internal sealing cover replaces integral compression of the external sealing cover, and the external sealing cover only needs to be fixedly matched with the external tube, so friction noise and friction marks generated through sliding fit of the external sealing cover and the external tube are reduced.
