Fig. 3 is the perspective view of the damping conductor shown in Fig. 2.
The specific embodiment
The invention will be further described below in conjunction with above-mentioned the drawings and specific embodiments.
As Fig. 1, shown in Figure 2, in the present embodiment, the described slow wrap-up that is used for winding matter coiler, comprise: centrepin 2, be fixed with torsion spring seat 3 with pin 1 on the centrepin 2, be set with torsion spring 4 on the torsion spring seat 3, one end of torsion spring 4 is fixedlyed connected with the damping conductor 5 on being sleeved on centrepin 2, the other end of torsion spring 4 is in and the connectionless free state of other part, the outside of damping conductor 5 is movably installed with damping shell 6, be respectively arranged with in damping conductor 5 and the damping shell 6 several layers can cooperatively interact suit damping cavity---its concrete structure is: referring to Fig. 2, shown in Figure 3, internal interval at damping conductor 5 is provided with several layers annulus wall 52, constitute damping cavity 51 between the adjacent annulus wall 52, equally, also be arranged at intervals with several layers annulus wall 62 in the inside of damping shell 6, constitute damping cavity 61 between the adjacent annulus wall 62, cooperatively interacting between them closed and be: annulus wall 52 can extend in the damping cavity 61 respectively, annulus wall 62 then can extend in the damping cavity 51 respectively, in each damping cavity 61 and damping cavity 51, be filled with damping grease, the effect of damping grease is the frictional force that increases between annulus wall 52 and the annulus wall 62, just increases the frictional force between damping conductor 5 and the damping shell 6.In the present embodiment, an end of centrepin 2 passes damping shell 6, and on centrepin 2 with steady pin 8 side's of being set with tenons 7, the effect of the side's of setting tenon 7 is to be convenient to install described slow wrap-up.
The using method of the slow wrap-up of said structure is: it is arranged on an end of coiler, during use, square tenon 7 is fixed in the mount pad, and mount pad is fixed on the wall usually, and an end that is wound with the pipe of coiling things such as screen, curtain then is fixedly set in the outside of damping shell 6.When wound items being pulled out when opening to a certain direction, the coiling thing drives damping shell 6 by pipe and rotates together, because the existence of damping grease, damping shell 6 can drive damping conductor 5 and rotate together, damping conductor 5 can drive torsion spring 4 and rotate together, in this course, the rotation direction of torsion spring 4 makes torsion spring 4 be in releasing orientation, make torsion spring 4 freely to rotate around torsion spring seat 3, thereby can like a cork wound items be pulled out and be opened to the desired position, and lock-bit under the effect of the automatic locking positioning device in coiler.When needs draw wound items in, then make automatic locking positioning device remove self-locking state, begin backrush under the effect of the returning spring of coiling thing in coiler, draw in, the coiling thing drives damping shell 6 backward rotation together by pipe, because the existence of damping grease, damping shell 6 also can attempt to drive damping conductor 5 and torsion spring 4 backward rotation together, but in this course, the rotation direction of torsion spring 4 can make torsion spring 4 be in the state of holding tightly, make torsion spring 4 tightly embrace the jail on torsion spring seat 3 and can not freely rotate, because an end of torsion spring 4 is fixedlyed connected with damping conductor 5, therefore damping conductor 5 also just can not freely rotate, like this, damping shell 6 can only overcome the resistance between itself and the damping conductor 5 and rotate, owing to be filled with damping grease between damping shell 6 and the damping conductor 5, increased frictional force, therefore the process of this backrush gathering just can only be carried out lentamente, thereby realize that the slow backrush of coiling thing is until the purpose of drawing in, stopped to touch the phenomenon that the coiler shell produces big noise, can prolong the service life of coiler because of the quick backrush of coiling thing makes its bottom end pulling bar.
