Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as Figure 1-3 As shown, the present invention includes an inner tube 20, an outer tube 10 and an outer cover 60 for sealing the two ends of the outer tube 10. It is characterized in that the inner tube 20 is rotatably connected inside the outer tube 10, and the outer surface of the inner tube 20 is closed. A curtain is rolled, and a spring set 80 is fixed in the inner cavity, and a buffer device for slowing down the rotation of the inner tube 20 is also connected between the inner tube 20 and one of the outer covers 60 . The buffer device includes: a shaft sleeve 30 , a damper 40 and an inner cover 50 . The outer surface of the shaft sleeve 30 is fixedly connected to the inner cavity of the inner tube 20; the damper 40 includes a rotating block 45 and a fixed seat 42 that can be fixedly connected to the inner cavity of the shaft sleeve 30, and t...

Abstract

The invention discloses a covering curtain winding device capable of buffering. The covering curtain winding device comprises an inner tube (20), an outer tube (10), and outer seal covers (60), wherein the outer seal covers are used for sealing two ends of the outer tube (10). The covering curtain winding device is characterized in that the inner tube (20) is rotatably connected inside the outer tube (10). A covering curtain is wound on the outer surface of the inner tube (20). A spring set (80) is fixed in the inner cavity of the inner tube (20). A buffering device for slowing down the rotation of the inner tube (20) is disposed between the inner tube (20) and one of the outer seal covers (60). Due to the fact that the winding device is provided with the buffering device, application operations is unaffected during pulling out, the retraction speed is reduced by 1.5-2.0 seconds during retraction, and impact is buffered effectively.

Description

technical field [0001] The invention relates to a material retracting device, in particular to a retracting mechanism for an object curtain. Background technique [0002] Curtains are generally used in automobiles, and are mainly used to cover the trunk with items, which plays a role of beauty and tidiness. Users have higher and higher requirements for interior space, comfort, and environmental protection. The covering curtain can meet the needs of users. It can cover the items in the trunk, isolate the trunk to save energy required for cooling, and protect the vehicle during sudden braking or driving. When bumping and overturning, it can prevent the items in the trunk from being thrown to the passenger seat and cause passengers to be injured. At the same time, the customer can support and cushion the product when pulling the product, which can avoid collision noise; in addition, the covering curtain can not only be integrated with the car The combination of modernization, ...
