Integrated shielding curtain winding device

Abstract

The invention discloses an integrated shielding curtain winding device, which comprises core iron, an inner pipe for winding a shielding curtain, and a spring ball and a torsion spring arranged in one end of the inner pipe, wherein the spring ball is formed by buckling a male spring ball and a female spring ball; a central hole coaxial to the core iron is preserved on the spring ball; one end of the core iron is connected with an outer seal cap, and the other end of the core iron is connected with a core iron fixing block; a compressed spring is also sleeved on the core iron and is arranged in the central hole preserved on the spring ball. According to the integrated shielding curtain winding device, three clamping tenons are arranged on the core iron and are used for fixing the core iron and relevant parts, the usage of partial parts is reduced, the product cost is reduced, the assembling is convenient, the whole stability is excellent, and meanwhile, the clearance between the shielding curtain and a side body can also be effectively improved.

Description

technical field [0001] The invention relates to a retracting device for a roller blind. Background technique [0002] Roll-up blinds are widely used in automobiles, offices and other places, and have gradually become an indispensable product in modern life. [0003] The retracting device of the shade in the prior art usually consists of a torsion spring, a core iron, and a roll rod. The torsion spring provides torsion for the retraction of the shade. Pendulum, usually for the convenience of installation, the retracting device will also have an additional compression spring, but this compression spring and torsion spring are separated, because there are many parts in the curtain itself, plus the additional compression spring and other external installation mechanisms, which not only cause inconvenience in the assembly of the covering curtain, increase labor costs, and reduce production efficiency, but also the coaxiality of the core iron and the spring in the prior art is no...

Pendulum, usually for the convenience of installation, the retracting device will also have an additional compression spring, but this compression spring and torsion spring are separated, because there are many parts in the curtain itself, plus the additional compression spring and other external installation mechanisms, which not only cause inconvenience in the assembly of the covering curtain, increase labor costs, and reduce production efficiency, but also the coaxiality of the core iron and the spring in the prior art is not high, causing the entire retraction and compression during the retraction and compression process. The stability of the device is greatly reduced, easy to shake and noisy
