Double-layer reel (001)

Abstract

1. The name of this design product: Double-layer reel (001). 2. Purpose of this product design: This product design is used to roll up film materials (such as photosensitive dry film or solder mask dry film). 3. The key point of the design of this product lies in its shape. 4. The picture or photo that best illustrates the design points: three-dimensional picture. 5. The rear view is the same as the main view, so the rear view is omitted; the right view is the same as the left view, so the right view is omitted; the top view is the same as the bottom view, so the bottom view is omitted; the rear view of component 1 is the same as the main view, so the rear view of component 1 is omitted; the right view of component 1 is the same as the left view, so the right view of component 1 is omitted; the top view of component 1 is the same as the top view, so the top view of component 1 is omitted. 6. Other situations that need explanation Other explanations: This design product consists of an inner shaft tube (component A in the cross-sectional view) and an outer shaft tube (component B in the cross-sectional view) and a support frame located between the inner shaft tube and the outer shaft tube (component C in the cross-sectional view, i.e. component 1). As shown in the cross-sectional view, the length of the inner shaft tube and the outer shaft tube can be extended as needed, and different lengths can be made as needed. The number of support frames can be set according to the length requirements of the inner shaft tube and the outer shaft tube; in addition, the position of the support frame can be adjusted as needed, as shown in the reference object.
