Embodiment Construction

[0008] Choose steel wire or iron wire with certain mechanical properties, and make left-hand helical wire (2) and right-helical wire (4) with different rotation directions from the middle part, install one end in the bearing seat (8), and connect the other end with the motor drive shaft. Fix, respectively install the left nut (3) and the right nut (5) on the left helical wire (2) and the right helical wire (4), and both pass the left hanging wire (6), the right hanging wire (7) and the left Ring (9), right ring (10) link to each other, and ring is sleeved on the guide wire (11), so, when motor rotates by different directions, just can drive curtain A, B to realize the action of opening and closing. If it is a single-sided curtain, it only needs to use the screw thread in the same direction, and match other parts accordingly.

Abstract

The invention discloses an electric spiral curtain machine. In the machine, a direct spiral thread drive method is adopted, a spiral thread made from plastic materials is arranged above the upside of a window in whole-length width, the spiral thread is driven by an electromotor, a nut is arranged on the spiral thread and the freedom of rotation of the nut per se is limited but the freedom of rotation along a spiral thread shaft is not limited, so, when the spiral thread rotates, the nut moves along the axial direction of the spiral thread, and the nut can move leftwards or rightwards by controlling the different rotation directions of the spiral thread. Thus, the opening and closing operations of a curtain can be realized by the nut. The curtain can be halved and opened and closed from the two opposite sides by simply changing the spiral direction of the spiral thread from the middle part to the two different spiral directions and adding corresponding parts accordingly.

Description

technical field [0001] The invention relates to a spiral curtain machine, in particular to an electric spiral curtain machine, which belongs to the technical field of daily light industrial products. Background technique [0002] At present, the main transmission mode of the electric curtain machines sold on the market is that the electric motor drives a small speed reducer, and the speed reducer drives the pulley mechanism to complete the closing of the curtain. The disadvantages of this kind of transmission mechanism are: the mechanism is relatively complicated, prone to failure, installation and maintenance are troublesome, and the cost price is also high. In addition, the materials used in this type of transmission mechanism are all made of metal materials, so not only the cost is high, but also it is not conducive to the saving of precious metal materials. Contents of the invention [0003] In order to overcome the disadvantages of the existing electric curtain machi...
