Sheet rolling door

Abstract

A sheet material roller shutter door is provided, when shedding caused by outer forces occurs to the sheet material of the sheet material roller shutter door, the shed sheet material can return smoothly to a sheet material guiding member without tough motions. The sheet material roller shutter door is provided with: the sheet material, and the sheet material is provided with a plurality of transverse core material arranged by intervals from top to bottom; a transverse sheet material box containing and rotatably freely shaft-supporting a sheet material barrel, and the sheet material barrel is used for winding and releasing the sheet material in an up and down direction; and support columns configured on two left and right end portions of the sheet material box. Inner side of the left and right columns is formed with the sheet material roller shutter door, and the sheet material roller shutter door can guide elevation of left and right end of the core material in an inner guide rail of the sheet material guiding portion. A limiting portion are arranged on middle portions on left and right direction of front and back side wall of a guide groove in the inner guide rail, and the limiting portion protrudes to the groove and can be moved back and forth through elastic deformation. In a state in which a guiding protrusion is inserted into the guide groove, the guiding protrusion is clamped in the limiting portion, and motion to an inner side is prevented; and when a force bigger than or equal to a specified amount is applied in an inward direction of the guiding protrusion, a card set of the guiding protrusion can be elastically shed off.

Description

technical field [0001] The present invention relates to a sheet rolling door that can be installed at the entrances and exits of buildings such as factories and warehouses, partitions, and various devices. Background technique [0002] So far, the well-known door-shaped sheet rolling shutters are installed at the entrances or partitions of buildings such as factories and warehouses, which are provided with sheet boxes and pillars for built-in sheet rolls for winding sheet material and the sheet is released, the sheet is provided with a plurality of linear core materials with the width direction of the sheet, the pillars are arranged at the left and right ends of the sheet box, and the guide rails are formed on the left and right inner parts of the pillars (inside Guide rail), insert the two ends of the above core materials into the guide rail (inner guide rail) for lifting and guiding. In addition, when inserting the core material into the guide rail, a core material suppor...

AI Technical Summary

Problems solved by technology

However, since the core material deeply inserts the core material supporting tool with weak fatigue strength for the shaft-supported roller into the guide rail, in the case where the sheet is subjected to a strong load in the front-rear direction, it is mainly to make the core material supporting tool large. After a wide range of deflection, it is separated from the guide rail, so in the long-term use process, the core material support tool is bent and deformed

And, when the core material support tool is deformed, it cannot be properly flexed with respect to the fluctuation of the pushing load in the front-back direction, which prevents the core material from detaching from the guide rail. Issues such as damage to related components, etc.
