Fig. 2 is the left and right side-looking schematic diagram of the structure of the left and right sides of the present utility model rope sheave and associated fitting.
The specific embodiment
Referring to Fig. 1, the stepless roller blind of heightening of the utility model, comprise left and right sides mount pad 1, torsion spring 2, mandrel 3, reel 4, cord 5, Zola's spring 6, right extension spring 7, left wire rope 8, right wire rope 9, left rope sheave 10, right rope sheave 11, pull bar 12, left rope clamp 13, right rope clamp 14, self-locking roller 15, self-locking silently 16 and self-locking support 17.Torsion spring 2 wherein, mandrel 3, reel 4, self-locking roller 15, self-locking silently 16 and self-locking support 17 and be combined into drum mechanism built and be installed in rotation between the mount pad of the left and right sides, self-locking roller 15 and self-locking silently 16 be arranged on two ends and respectively with 1 rotatable linking to each other of left and right sides mount pad, reel 4 is connected self-locking roller 15 and self-locking silently between 16,17 middle parts that are installed in the reel 4 are supported in self-locking, mandrel 3 is installed in self-locking roller 15 and self-locking and supports between 17, between the self-locking roller 15 that torsion spring 2 is installed in and the self-locking support 17 and be set on the mandrel 3.Cord 5 is wound on the reel 4, and pull bar 12 is connected the lower end of cord 5.Zola's spring 6 vertically is arranged on the inboard of left mount pad 1, and its upper end is fixedly linked with left mount pad 1, and the lower end is a free end, and right extension spring 7 vertically is arranged on the inboard of right mount pad 1, and its upper end is fixedly linked with right mount pad 1, and the lower end is a free end.Left side rope sheave 10 is installed in the left end in the pull bar 12, and right rope sheave 11 is installed in the right-hand member in the pull bar 12.The upper end of left side wire rope 8 links to each other with Zola's spring 7, left side wire rope 8 passes left rope sheave 10 successively and right rope sheave 11 is drawn downwards, right wire rope 9 passes right rope sheave 11 successively and left rope sheave 10 is drawn downwards, the lower end that left side rope clamp 13 is connected right wire rope 9 is with right wire rope 9 downward tensionings, and right rope clamp 14 is connected the lower end of left wire rope 8 with left wire rope 8 downward tensionings.
Referring to Fig. 2, left and right sides rope sheave 10 in the utility model, 11 are respectively equipped with front and back two circle groovings, grooving A and back grooving B before comprising, when assembling, left wire rope 8 can be passed successively the back grooving B of left rope sheave 10 and the back grooving B of right rope sheave 11 draws downwards, and right wire rope 9 is passed the preceding grooving A of right rope sheave 11 successively and the preceding grooving A of left rope sheave 10 draws downwards, also left wire rope 8 can be passed successively the preceding grooving A of left rope sheave 10 and the preceding grooving A of right rope sheave 11 draws downwards, and right wire rope 9 is passed the back grooving B of right rope sheave 11 successively and the back grooving B of left rope sheave 10 draws downwards, be in a word to make left and right sides wire rope 8,9 are the front and back distribution and the cross-shaped attitude in the front in pull bar 12.
The stepless roller blind of heightening of the utility model will make torsion spring 2 reach certain pretightning force when mounted, its operating principle is: with the past drop-down pull bar 12 of hand, when pretightning force that firmly surpasses torsion spring 2 and the frictional force sum between left and right sides rope sheave 10,11 and the left and right sides wire rope 8,9, pull bar 12 just drives reel 4 dextrorotations by cord 5 then moves downward, the pretightning force of torsion spring 2 increases simultaneously, pull bar 12 is downward more, and the pretightning force of torsion spring 2 increases manyly more.When pull bar 12 is moved desired height to, unclamp hand, at this moment, the frictional force between left and right sides rope sheave 10,11 and the left and right sides wire rope 8,9 stops at the position when unclamping hand, i.e. user's desired height greater than the pretightning force of torsion spring 2 increases.When not needing sunshade, with hand pull bar 12 up, when thrust surpasses pretightning force that torsion spring 2 increases and the frictional force sum between left and right sides rope sheave 10,11 and the left and right sides wire rope 8,9, the pretightning force of torsion spring 2 is crispaturaed and is driven reel 4 and be rotated counterclockwise and furl cord 5, pull bar 12 moves upward more, the pretightning force of torsion spring 2 discharges manyly more, the pretightning force during last remaining the installation.Unclamp hand and then keep roller blind and remain static, and in the effective travel of cord 5, any position can be stopped, promptly the utility model stepless heighten roller blind can be in the effective travel of cord 5 regulated at will sunshade height, realize stepless heightening.
