Detailed structure of the present utility model in above having done in conjunction with the accompanying drawings to be described in detail in the narration realization goal of the invention technical scheme, repeats no more herein.
The utility model mainly is made up of three parts;
1. volume rises device:
(1) motion and position-limit mechanism: comprise reel 11, guide cylinder 12, slide block 13, mandrel 14;
(2) spring mechanism: comprise torsion spring 15, left and right torsion spring seat 152,151;
2. square shaft one-directional rotation and torsion spring pre-tightening mechanism: comprise axle sleeve 41, the collar 42, bolster 43, torsion spring 44, key 45;
3. reducing gear: cover 161, overcoat 162, damping material 164 in comprising.
Its groundwork principle is as follows:
1. spur the draw ring 302 of bottom bar 301 downwards, driving reel 11 by cord 3 rotates, reel 11 drives guide cylinder 12 and rotates in the same way, at this moment the feather key piece 121 in the guide cylinder, block (referring to the slide block plane outspread drawing) and drive slide block at the position C of the ditch shape chute of slide block 13 and also radially rotate, because of slide block 13 is enclosed within on the square shaft 122, drive square shaft and rotate, simultaneously torsion spring 15 is tightened.
Loose one's grip when 2. cord 3 being controlled to the position that needs, under the effect of torsion spring 15, the reel revolution, because the special construction of the ditch shape chute of slide block 13, feather key 121 is stuck in the D place, and because of slide block is contained on the square shaft 122, square shaft again can only one-directional rotation, so this moment, reel 11 was stuck motionlessly, cord 3 is parked in desired location.
3. when needs cord 3 rises, need to spur again bottom bar 301 certain distances downwards, feather key 121 moves to the E position by the D position, loose one's grip the back under the reaction of torsion spring 15, feather key 121 will be along arrow direction among the figure, and cord 3 furls in the time of need being parked in certain position, spurs bottom bar 301 downwards, feather key is blocked in the D position once more, the cord stop motion.
4. deceleration device is to consider when roll up on the cord 3, owing to the torsion force of spring 15 is bigger, avoids rolling cushioning effect on too fast.Its structure mainly is to hang down the torsion of the torsionspring that disappears by damping oil.
During enforcement, described each assembly can be made with engineering plastics
