[0005] When the winding shaft and the curtain body are installed, one end of the curtain body is first fixed on the curtain body fixing portion of the clamping strip, the fixing mode is adhesion, welding, clamping connection, riveting or threaded connection and the like, then the clamping block of the clamping portion is matched with the clamping groove of the winding drum, the clamping strip fixed with the curtain body is clamped on the winding drum, the curtain body is wound after the clamping strip is clamped, and the winding shaft can be installed at the required position; when the curtain body needs to be replaced, the clamping block is only separated from the clamping groove, so that the clamping strip fixed with the curtain body can be separated from the winding shaft, which is convenient to install and replace.

[0006] Further description of the above technical solutions is as follows:

[0007] The clamping groove is generally in the shape of a Chinese character "KU", and the clamping block is in the shape of an inverted T, and the clamping block has elasticity. When clamping, the clamping block is deformed by being extruded due to the elasticity, is extruded into the clamping groove and is then unfolded, so as to be fixed in the clamping groove; when disassembling, the clamping block is deformed and pulled out along the opening direction of the clamping groove, so as to disassemble the clamping strip from the winding drum.

[0008] Further description of the above technical solutions is as follows:

[0009] The curtain body fixing part is arc-shaped, and the bending angle is consistent with the outer circumferential surface of the winding drum, so that the curtain body will not be bent greatly when being wound on the winding drum, and the curtain body is prevented from being broken.

[0010] As a further description of the above technical solution:

[0011] The clamping part and the curtain body fixing part are integrally extruded, and the hardness of the curtain body fixing part is higher than that of the clamping part.

[0012] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:

[0013] 1. The curtain body and the winding shaft are installed by cooperation of the clamping block and the clamping groove, which is convenient and fast.

[0014] 2. The elastic clamping block is used to cooperate with the clamping groove by taking advantage of the easy deformation of the clamping block, so that the clamping is firm, and the disassembly and assembly are convenient.

[0015] 3. The curtain body fixing part is arc-shaped, and the bending angle is consistent with the outer circumferential surface of the winding drum, so that the curtain body is prevented from being bent excessively, and the probability of the curtain body being broken is reduced.

[0016] 4. The present application is suitable for almost all places where the winding shaft and the curtain body are needed (such as door and window shading curtain, anti-theft curtain, windproof curtain, greenhouse heat preservation curtain, vehicle shading curtain, photovoltaic module dustproof curtain, etc.), and has strong applicability.
