The specific embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment of damping unit, structure, feature and effect thereof according to the curtain folding and unfolding that the utility model proposes, describe in detail as after.

See also Fig. 2,3 and Fig. 4,5 shown in, the damping unit of the utility model curtain folding and unfolding mainly includes damper 10 and damper shell 20, can articulate with clutch pack 30 to link and each arrange in pairs or groups respectively roller shutter 40 and groups of shades 50, wherein:

This damper 10 which is provided with convex ring body 11, be provided with more than one group in the axle center 120 during in convex ring body 11 1 ends with shell 21 relative rotations, can produce the curved surface 12,121 of Volume Changes, end is established nose bar 13 in addition, central authorities establish an open-work 14 that runs through two ends, and be respectively equipped with first, second scrobicular ring 111,112 in convex ring body 11 1 ends top, lower surface, and on this first, second scrobicular ring 111,112, being nested with first,

second packing

15,16 respectively, end face extends a clamping groove 113 in addition.

This damper shell 20 is one to be sheathed on damper 10 outer rims, and the shell 21 that an inside has room 211 is set, and end central authorities extend the body of rod 23 that an axle center 22 that locking hole 221 arranged and other end protrude out, and the body of rod 23 is established the mortise 232 on a perforation 231 and the periphery.

This clutch pack 30 is one adjacent with damper 10, and it mainly includes protruding body 31 and flexible member 32, and these protruding body 31 1 ends extend a nose bar portion 311, and nose bar portion establishes 311 inside a perforation 312 that can stretch through for damper shell 20 1 end axle center 22; This flexible member 32 is to be set on damper 10 to hold nose bar 13 and protruding body 31 1 end nose bar portions 311 outer rims in addition, and one end 321 cards only push up in the clamping groove 113 of damper 10 pulls, and other holds 322 to be arranged on protruding body 31 inboards.

Please cooperate again and consult Fig. 3,4 and the utility model shown in Figure 5 when combination, this damper 10 is set on damper shell 20 and is injected with in the damping oil, and then utilize first packing 15 to be set in that first scrobicular ring 111 and second packing 16 are set in second scrobicular ring 112 and with after room 211 sealings, again with clutch pack 30 form articulate and utilize pad 24, retaining element 25 and axle center 22 locking one after, the perforation 231 of holding the body of rod 23 in damper shell 20 in addition and the axostylus axostyle 41 of roller shutter 40 form sockets and so as to as screw ... wait lock member 42 to be screwed into mortise 232 and lock windings.

In the time of please cooperating practical operation shown in Figure 5 to use again, be that the utility model damping unit combining is when roller shutter 40, when furling casement 43 in the counterclockwise direction, the protruding body 31 of clutch pack 30 is along with rotation counterclockwise, because the direction of rotation and flexible member 32 hands of spiral are in the same way, so produce the binding effect with clutch pack 30, drive 13 rotations of damper 10 nose bars, and and then drive damper 10 and the fixed axostyle 41 be enclosed within damper shell 20 rooms 211 and relatively rotate, because when damper shell 20 internally-damped oil are arranged on axle center 120 with shell 21 relative rotations to damper 10, can produce the curved surface 12 of Volume Changes, 121, make its damping oil by slow gradually fast damping action, the speed that furls of casement 43 thereby slow down.When launching casement 43 along clockwise direction, clutch pack 30 also clockwise rotates, but because of direction of rotation opposite with flexible member 32 hands of spiral, so do not produce the binding effect with clutch pack 30, this moment, the rotation of protruding body 31 can not drive damper 10 nose bars 13, its damper 10 is not rotated by clutch pack 30 and rotates, so damper 10 transfixions, clutch pack 30 is made lost motion on damper 10, so the expansion of casement 43 is not subjected to any stopping and very smooth and easy effect.

Again, shown in Fig. 6,7-1 and Fig. 7-2,8, the utility model also forms a damping unit by a damper 10a and a damper shell 20a, can change the assembling mode neatly when using, it can be assemblied in reel 521 back sides of groups of shades 50 1 end stay cord folding and unfolding control device 51 fastening roller set 52; When casement 53 launched in the counterclockwise direction, damper 10a and fastening roller set 52 rotated counterclockwise simultaneously, and the damping oil generation damping action of borrowing damper 10a and damper shell 20a to insert therebetween, and the development rate of casement 53 is slowed down; When casement 53 when furling clockwise, damping unit seem very smooth and easy, and then also furling of casement 53 can be carried out swimmingly along with clockwise rotating and not having any stopping and be lost motion.

In sum, damping unit described in the utility model respectively is assemblied on roller shutter 40 and the groups of shades 50, roller shutter 40 casements 43 are furled slow down, launch smooth and easy, or make groups of shades 50 casements 53 launch to slow down, furl operating effect smoothly, thereby can adapt to different curtain easily.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art are not in breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
