Description

Rolling shutter sheet

Technical Field

The utility model belongs to the technical field of rolling slats door/roll up curtain window, especially, relate to a roll up curtain piece.

Background

At present, a rolling door or a rolling window (rolling door/window for short) becomes a daily life facility, and has the characteristics of convenience in use, attractive and elegant appearance, easiness in storage, space saving and the like. However, the roller blinds/windows are either one large roller blind formed integrally or a plurality of roller blind sheets are connected together. However, the former has large material volume, difficult manufacturing and processing and poor universality; although the single roller shutter piece is small in size, easy to manufacture and good in applicability, the plurality of roller shutter pieces are installed into the roller shutter and need to be connected through the connecting piece, on one hand, the gap at the connecting position is large and not firm and not attractive, and on the other hand, the manufacturing cost and the installation difficulty are increased due to the fact that the parts are numerous.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a roll up curtain piece that novel structure, small in size, simple manufacture, dismouting are easy, the appearance is pleasing to the eye firm.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the rolling curtain sheet comprises a curtain sheet main body, wherein a male joint and a female joint which are matched are respectively arranged at two ends of the curtain sheet main body; the male connector is an outer protrusion, and the female connector is an inner groove.

The outer protrusion is crescent, the inner groove is segmental, and the segmental inner wall is provided with a limiting protrusion.

The curtain sheet main body is of a double-layer structure, in the section of the double-layer structure, the inner layer is a rolling surface, the outer layer is a curtain surface, the rolling surface is an arc surface, the curtain surface is a plane, and the rolling surface and the curtain surface are connected through a supporting sheet.

The end surfaces of the two ends of the curtain sheet main body are planes vertical to the curtain surface except the male joint and the female joint, and the outer protrusion is connected with the crescent back part protruding out of the end surfaces by the fulcrum on the end surfaces.

The crescent arc above the fulcrum is matched with the segment arc above the limiting protrusion, and the crescent arc below the fulcrum is matched with the segment arc below the limiting protrusion.

Aiming at the problems of the roller shutter of the prior roller shutter door/window, the inventor designs and manufactures the roller shutter sheet used in cooperation. The rolling curtain sheet comprises a curtain sheet main body, wherein a male joint and a female joint which are matched are respectively arranged at two ends of the curtain sheet main body; the male connector is an outer protrusion, and the female connector is an inner groove. The outer protrusion is crescent, the inner groove is segmental, and the segmental inner wall is provided with a limiting protrusion. The rolling shutter sheets are correspondingly spliced through the male connectors and the female connectors of the rolling shutter sheets, namely the male connectors and the female connectors of the adjacent rolling shutter sheets are matched to obtain the corresponding rolling shutter, and the limiting bulges can ensure that the curtain surfaces of the rolling shutter sheets are in the same plane after the rolling shutter door/window body is closed, the rolling shutter surfaces are tightly connected, and the curtain sheets are not loosened. In a word, the utility model discloses novel structure, small in size, simple manufacture, dismouting are easy, the appearance is pleasing to the eye firm, have reduced the connecting piece between the roll curtain piece moreover, reduce weight, reduced manufacturing cost, are the outstanding substitute of current roll curtain.

Detailed Description

As shown in fig. 1 to 7, the rolling shutter of the present invention comprises a shutter body, wherein both ends of the shutter body are respectively provided with a male joint and a female joint which are matched with each other; the male connector is an outer protrusion, and the female connector is an inner groove. Wherein the content of the first and second substances,

the curtain sheet main body is of a double-layer structure, in the section of the double-layer structure, the inner layer is a rolling surface, the outer layer is a curtain surface, the rolling surface is an arc surface, the curtain surface is a plane, and the rolling surface and the curtain surface are connected through a supporting sheet. The outer bulge is crescent, the inner groove is segmental, and the inner wall of the segmental shape is provided with a limit bulge; the end surfaces of the two ends of the curtain sheet main body are planes vertical to the curtain surface except the male joint and the female joint, and the outer protrusion is connected with the crescent back part protruding out of the end surfaces by the fulcrum on the end surfaces. The crescent arc above the fulcrum is matched with the segment arc above the limiting protrusion, and the crescent arc below the fulcrum is matched with the segment arc below the limiting protrusion.

As shown in figure 2, the utility model discloses a roll up curtain corresponds the concatenation through its male joint and female joint by the above-mentioned roll of curtain piece of polylith, is about to the male joint and the female joint cooperation of adjacent roll of curtain piece, can obtain corresponding roll up curtain.

By applying the utility model, the upper and lower curtain sheets do not need nailing or fixing by connecting pieces, the direct nesting and installation of the male and female connectors are simple, the curtain sheets are tightly connected, no gap exists on the curtain surface, and the strength is improved; when the roller shutter is folded and unfolded, the roller shutter sheets flexibly rotate around the circular segmental inner grooves along with the crescent-shaped outer protrusions to realize the rolling and unfolding of the roller shutter; moreover, the limiting bulge can play a role in limiting the roller shutter, namely after the roller shutter door/window body (the roller shutter is unfolded), the shutter surfaces of each roller shutter sheet are positioned on the same plane, the roller shutter surfaces are tightly connected, and the shutter sheets are not loosened; when the curtain is rolled up, the curtain sheet is prevented from being excessively curled, so that the damage of the curtain sheet is prevented, and the service life is prolonged.
