Such a heat-insulating cover switch comprises a forward / reverse rotation for winding and unwinding the wound traction rope on a take-up drum and releasing / disengaging the power by the clutch.

On the other hand, the clutch is formed by a pair of left and right clutches, a screw is formed on the surface of the clutch, and a reciprocating clutch reciprocating by a screw is formed and the front end of the reciprocating clutch is engaged with the engaging projections of the cooperating clutch, Wind it.

Therefore, one of the pair of clutches is interlocked and interlocked according to the rotational direction of the driving force, and the other is revolved so that one winding drum is constituted to wind the rope, while the other rotates to unroll the rope.

However, such a drive is complicated in the structure of the reciprocating clutch and the interlocking clutch, and an operation error occurs due to inaccurate occlusion because the surface contact of the engaging projection is not properly performed.

In addition, due to the inaccuracy of the occlusion, the amount of winding and the length of the rope are different from each other, so that the heat shield can not be wound and unwound constantly, causing the heat shield to stop in the middle. Of course, there is a problem that frequent breakdown occurs.

In order to solve the above-mentioned problems, it is an object of the present invention to precisely bite a pair of reciprocating and interlocking clutches operated by the operation of a heat-insulating cover switch, And to improve the durability so as not to occur.

In order to accomplish the above object, the present invention provides a drive device for a heat insulating cover switch for a vinyl house, which comprises a case in which a case is divided into first and second compartments, In a state where the first internal gear and the second internal gear are inserted in the second compartment and the second internal gear is inserted into the second compartment, the internal gears of the first and second internal gears are arranged concentrically around the axes of the planetary gears and the planetary gears The first and second coupling discs are engaged with the pinion gear in the left and right directions, the rotary shaft of the helical gear and the planetary gear is engaged and rotated, the driving disc is fastened to the second coupling disc, The reciprocating clutch, the guide tube, and the flange are sequentially arranged on the outer circumferential surface of the drive disk in a state where one side of the spline is engaged with the drive disk The sum is, the other side of the splines and reciprocating clutch bite and being detachably interlocked with interlocking clutch disk is engaged, interlocking disk, characterized by consisting of interlocking splines, and the coupling, a protective cover.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, there is provided an effect of accurately performing winding and unclamping operations of the heat shield cover due to quick engagement and detachment operation of the reciprocating clutch driven by the motor and the interlocking clutch.

In addition, since the detachable structure of the reciprocating clutch and the interlocking clutch is simple, there is no residual space, and the manufacturing is facilitated, so that an economical effect of reducing the manufacturing cost can be expected.
