Abstract

The utility model relates to an improved rolling shutter sheet. The utility model is composed of a sheet body segment, an outer hook head which is integrally formed on one end of the sheet body segment and an inner hook head which is integrally formed on the other end of the sheet body segment, wherein, the outer hook head and /or the inner hook head comprises at least two circular arc segments, and each circular arc segment is smoothly connected. A hinge cavity which can contain the circular arc segments of the outer hook head is formed on the circular arc segments of the inner hook head. The outer hook head and the inner hook head of two adjacent rolling shutter sheets are mutually in sleeve joint; the outer hook head of one rolling shutter sheet is contained in the hinge cavity of the inner hook head of the other hinge rolling shutter sheet after the sleeve joint. When two adjacent rolling shutter sheets are on the same plane, the other rolling shutter sheet can rotate in two directions around the outer hook head of one rolling shutter sheet. The rolling shutter sheet can be curled in double directions (that is to say the rolling shutter sheet can be curled in both directions); in addition, when external force acts on a rolling shutter, big noise can not be produced.

Description

Improved Sheet material for coiled curtain

Technical field:

The utility model relates to a kind of Sheet material for coiled curtain, more particularly, relates to the rolling door of occasions such as a kind of garage, warehouse and show window or the Sheet material for coiled curtain that roller shutter window uses.

Background technology:

Rolling door or roller shutter window generally comprise roller shutter, be the vertical guide rail of roller shutter guiding and the reel of band drive unit or wind spring, wherein roller shutter is combined by the light metal roller shutter sheet of multi-disc extrusion molding, and roller shutter sheet of the prior art exists many deficiencies, CN01267927.5 number Chinese utility model patent as notice of authorization on the 21st August in 2002, a kind of Sheet material for coiled curtain is disclosed, this Sheet material for coiled curtain is by a slice figure and integrally formed with this sheet figure, the outer gib head and the interior gib head that lay respectively at these sheet figure two ends constitute, outer gib head and interior gib head are positioned at the same side of sheet figure, outer gib head has a hinge cavity that can hold gib head in the adjacent Sheet material for coiled curtain, hinge cavity has an opening towards the sheet figure back side, the external surface of interior gib head has identical radius of curvature with the part that the hinge cavity inner surface cooperates, the sheet figure is formed with a spacing fin with the joint portion of outer gib head, be formed with a spacing convex with the joint portion of interior gib head, when Sheet material for coiled curtain is in plumbness, the spacing fin and the spacing convex of adjacent two Sheet material for coiled curtain are promptly engageable, thereby can prevent effectively that dust from entering hinge cavity.But owing to this roller shutter sheet can only curl to a direction, thereby the installation site of reel there is strict restriction, can't satisfies the needs of various door bodies, also make that the installation of reel is comparatively inconvenient simultaneously.Therefore, the applicant improves said structure, and the roller shutter sheet after will improving on August 26th, 2002 has proposed patent application to State Intellectual Property Office, its application number is 02246438.7, the outer gib head of this roller shutter sheet and interior gib head comprise an arc section and the bending part that extends internally of the end of this arc section certainly, the junction of arc section and bending part forms spill bending fulcrum, the outer gib head of adjacent two Sheet material for coiled curtain and the mutual socket of interior gib head, the free-ended termination of bending part of the described outer gib head of a Sheet material for coiled curtain and interior gib head is supported in the inner surface of bending fulcrum of the correspondence of another Sheet material for coiled curtain after the socket.Though this Sheet material for coiled curtain can two-wayly curl, because the mating part of interior gib head and outer gib head has bigger gap, when wind or other external force act on roller shutter, will bump and rub owing to rocking mutually between each roller shutter sheet, produce noise greatly.

The utility model content:

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of and can not only two-wayly curl (promptly all can curl to both direction), and when external force acts on the roller shutter sheet, also can not produce the improved Sheet material for coiled curtain of big noise.

The improved Sheet material for coiled curtain that provides according to the utility model, by a slice figure, be integrally formed in an outer gib head of this sheet figure one end and be integrally formed in this sheet figure other end one in gib head constitute, described outer gib head and/or described interior gib head comprise at least two arc sections, smooth connection between each arc section, the described arc section of described interior gib head forms the hinge cavity of the described arc section that can hold described outer gib head; The described outer gib head of adjacent two Sheet material for coiled curtain and described in the mutual socket of gib head, the described outer gib head of a Sheet material for coiled curtain is contained in the described hinge cavity of interior gib head of another Sheet material for coiled curtain after the socket; When adjacent two Sheet material for coiled curtain were in same plane, described another Sheet material for coiled curtain can rotate to both direction around the outer gib head of a described Sheet material for coiled curtain.

The improved Sheet material for coiled curtain that provides according to the utility model also has following attached technical characterictic:

Described outer gib head comprises first arc section and second arc section of smooth connection, and described first arc section and second arc section all are the circular arc of certain value radius, and its central angle is all 160 ° to 200 °.

Gib head comprises an arc section in described, and described arc section is the circular arc of certain value radius, and its central angle is 210 ° to 270 °.

Described figure is a bending flat board that is shaped by the sheet material of uniform thickness, the partially-formed part that a depression is arranged of its contiguous described outer gib head, the part of described depression and described in formation one cavity between the gib head.

Gib head partially-formed had an outward extending fin in the vicinity of described figure was described, and the cross section of this part of described figure is circular-arc.

A distance apart from described fin on described figure is formed with a decorative depressions.

The relative prior art of improved Sheet material for coiled curtain that provides according to the utility model has following advantage: because outer gib head and interior gib head all are smooth arc section, thereby after adjacent two Sheet material for coiled curtain connect together, not only can two-wayly curl (promptly all can curl) to both direction, and the interior gib head and the outer gib head of fit cooperate comparatively tight mutually, even when having wind or other external force to act on roller shutter, can be owing to the mutual collision between each roller shutter sheet and friction produce big noise yet.
