Abstract

The utility model relates to an improved rolling-curtain drawing system. The utility model is mainly composed of a roller, a draw bead chain, and drawing. The utility model is characterized in that the curtain cloth and the roller do not use the pasting method of double-surface rubber cloth, but uses the method that the roller is provided with a clamp groove, a rolling head of the curtain cloth is directly sheathed in the clamp groove, and thus the connection of the curtain cloth and the roller is realized. After the connection method is used, the utility model saves the trouble that the double-surface rubber cloth is repetitively pasted when the curtain cloth is folded, and is especially suitable for window curtains with the requirement that the curtain cloth is frequently folded and washed.

Description

A kind of modified roller shutter draws system

Technical field

The utility model relates to the drawing system of a kind of parts of curtain, particularly a kind of roller shutter.

Background technology

The drawing system of known roll type curtain, mainly form by cylinder (1), cord (3) kerve (4) and bead chain (5), wherein cord (3) upper end and cylinder (4) is connected, it is an end that contacts with cylinder (1) at cord (3), with cloth insertion sheet (2), both are pasted together realize.The defective of this method of attachment is inconvenience folding dress, when cord (3) needs folding to wash, cord (3) must be torn from cylinder (1), after waiting to clean airing, must be with new cloth insertion sheet (2) that cord (3) and cylinder (1) is bonding once again, and extremely inconvenient.

Summary of the invention

The purpose of this utility model is to improve the method for attachment of above-mentioned cord (3) and cylinder (1), makes the folding dress between cord (3) and the cylinder (1) become very easy.

This reality has novel above-mentioned purpose to realize by following scheme: when making roller (1), arbitrary position at cylinder (1) periphery, make a draw-in groove (11) that traverses cylinder (1), draw-in groove (11) is by inner chamber (111) and lack seam (112) formation, wherein the diameter of inner chamber (111) stitches (112) width much larger than lacking; Then with the upper end of cord (3), be rolled into the cord volume head (31) that the diameter dimension of the inner chamber (111) of a diameter size and draw-in groove (11) is in active relationship.During installation, with cord volume head (31), pierce into the inner chamber (111) of draw-in groove (11) from a side of the draw-in groove (11) of cylinder (1), cord (3) then passes from the scarce seam (112) of draw-in groove (11), owing to lack the diameter of the width of seam (112) much smaller than cord volume head (31), cord volume head (31) will be stuck in the inner chamber (111), cord (3) can be hung in the draw-in groove (11) of cylinder (1), when needs with cord (3) when rolling, as long as pulling bead chain (5), by the rolling of cylinder (1), because draw-in groove (11) blocks cord volume head (31), cord (3) just can be rolled-up with the rolling of cylinder (1) naturally; When the needs folding is washed cord (3),, just can easily cord (3) be pulled away from cylinder (1) as long as cord volume head (31) is pulled out gently from a side of draw-in groove (11).

Advantage of the present utility model is between cord and the cylinder that folding adorns convenient and swiftly, has saved traditional trouble of pasting with cloth insertion sheet repeatedly.

The specific embodiment

A kind of roll type curtain is made up of drawing system, cord 3 and kerve 4, and the system that wherein draws is made up of cylinder 1, drawing sign indicating number 7, drawing 8, tail sign indicating number 6 and bead chain 5; There is kerve lid 41 at the two ends of kerve 4; There is upper end cord volume 31 upper end of cord 3, and there is lower end cord volume 32 lower end; Periphery place at cylinder 1, the draw-in groove 11 that traverses cylinder 1 is arranged, draw-in groove 11 is made of cylindrical cavity 111 and scarce seam 112, the diameter dimension of the diameter dimension of inner chamber 111 and upper end cord volume 31 is in active relationship, and the seam that lacks seam 112 is wide, only is a bit larger tham the thickness of cord 3 and little more than the diameter of inner chamber 111.During installation, earlier upper end batching head 31 is packed into the inner chamber 111 of cylinder 1 from an end, because the diameter of upper end cord volume 31 is much larger than the width that lacks seam 112, therefore upper end cord volume 31, after packing into draw-in groove inner chamber 111, just be stuck in wherein, cord 3 then energy is also hung below cylinder 1, and is slided up and down with the rotation of cylinder 1 by lacking seam 112.The mounting method of remaining part is identical with known drum-type curtain.

Claims

1, a kind of modified roller shutter draws system, by cylinder (1), bead chain (5), draw (8), draw sign indicating number (7), tail sign indicating number (6), tailing axle (9) is formed, it is characterized in that at cylinder (1) periphery place, a draw-in groove (11) that traverses cylinder (1) is arranged, draw-in groove (11) is by cavity (111) and lack seam (112) formation, the diameter of cavity (111) is big more than the width that lacks seam (112), the width that lacks seam (112) then is a bit larger tham the thickness of cord (3), the upper end of cord (3), make the cord volume head (31) that diameter dimension and cavity (111) diameter dimension is in active relationship, during installation, the end of cord volume head (31) from draw-in groove (11) directly packed into, at this moment cord (3) can pass from lacking seam (112), thereby cord 3 is hung in cylinder (1) below and slide up and down with the rotation of cylinder (1).
