The utility model which has smooth engaging and disengaging when working has reasonable design, convenient operation and long service life.
Description
The utility model belongs to the improvement of curtain, curtain arrangement of clutch.
Existing curtain, curtain arrangement of clutch are widely used in people's production field, such as curtain, the curtain structure of messenger drive, its weak point is to beat owing to the rope tension tense-lax differs, and the rope that goes offline is and stuck, and the user is difficult to handle, influencing service life use inconvenience, fault more.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and the positive and negative spiral shell mosquito of a kind of curtain, the curtain Isolating Switch device that provides.
The purpose of this utility model can reach by following measure: in the centre position of box body left and right screw rod is set, left and right screw rod thread is opposite, nut is set on screw rod, nut is connected by the connecting rod ring that draws that draws on the circuit rail left and right with being arranged at screw rod, screw rod, draw the circuit rail and be arranged in the box body by supporting base, the screw rod center is supported by supporting-point, and screw rod is by the transmission mechanism transmission.
The utility model has following advantage compared to existing technology: because the utility model is to prior art improvement structurally, thereby to have one be that clutch is steady; The 2nd, easy to operate, long service life; The 3rd, novel in design, rational in infrastructure.
The accompanying drawing drawing is described as follows:
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to accompanying drawing 1-2, the utility model is by box body (1), right screw rod (2), draw ring (3), nut (4), nut tie point (5), connecting rod (6), draw ring tie point (7), draw circuit rail (8,9), left side screw rod (10), supporting base (11), Screw rod bearings point (12), transmission mechanism (13) is formed, in box body (1) centre position right screw rod (2) and left screw rod (10) are set, left side screw rod (10), right screw rod (2) thread is opposite, in left screw rod (10), on the right screw rod (2) nut (4) is set, in left screw rod (10), right screw rod (2) both sides are provided with draws circuit rail (8,9), drawing circuit rail (8,9) go up setting and draw ring (3), connecting rod (6) one ends with draw the ring tie point (7), the other end and nut tie point (5), draw circuit rail (8,9) and left screw rod (10), right screw rod (2) is supported by supporting base (11), (12) be the Screw rod bearings point, (13) are transmission mechanisms.
Operation principle: rotate at the drive bottom left screw rod (10) of transmission mechanism (13), right screw rod (2), drive nut (4) clutch round about on the screw rod, because the clutch of nut (4), drive by connecting rod (6) and to be arranged at drawing about screw rod and to draw ring tie point (7) on the circuit rail (8,9), be arranged at the casement that draws on the ring tie point (7) or curtain clutch reposefully.
