Abstract
The utility model relates to an electrically-driven curtain which adopts a transmission mechanism comprising a screw rod and a nut with external threads, wherein, the screws with external threads are formed in the way that the single bodies of the screw rod with external threads are spliced by connecting shafts to be assembled into a whole; both ends of the single bodies of the screw rod with external threads are half cylinders, and the axial centers of single bodies of the screw rod with external threads are provided with blind holes in which the connecting shafts can be plugged. The right lower part of the screw rod with external threads is provided with a supporting rod which is sheathed with a hanging ring, and is also provided with a transmission mechanism which is drawn and closed by the manual work. The utility model which adopts a spiral type propelling principle has the advantages of novel structure, flexible transmission, safe control and strong practicability. In addition, when power failure happens, the curtain can be opened and closed manually.
Description
The utility model relates to drawing back and closing device of on positive axis threaded curtain, relates in particular to a kind of electrically driven curtain.
Existing electrically driven curtain is that motor is walked on guide rail to drive drawing back and closure of curtain mostly, and it is big that the lead song is stretched frequency, easily causes the electric leakage accident.And when having a power failure, can not manually draw back again and closure.
The purpose of this utility model is to remedy the deficiencies in the prior art to propose a kind of improved electrically driven curtain.
The purpose of this utility model is achieved by the following technical programs.
This electrically driven curtain, comprise motor, be fixedly connected on the decelerator of motor output shaft, the decompression rectification power of positive and negative rotation is provided to motor by two-way switch control, one end is by the support rest, the external threaded of the other end and reducer gear interference fit and be mated the nut of forming screw-and-nut mechanism, and the suspension ring that link to each other with the little ring that is connected curtain, it is characterized in that described external threaded is that semicylinder and axle center are provided with an external threaded monomer that can insert the blind hole of connecting axle and peg graft through connecting axle and form one, the rotating shaft at connecting axle double as external threaded two ends by two ends; Be provided with the cramp bar that is with above-mentioned suspension ring under external threaded, distance bracket end suspension ring farthest are fixed on the above-mentioned nut through a gripper shoe; With the connecting axle of reducer gear interference fit be provided be with on it rope and be positioned under it a wire-drawing wheel be combined into the wheel that draws of artificial drawing transmission mechanism.
The utility model adopts spiral principle of propeller, novel structure, and ensuring smooth transmission, control safety can manually be drawn back and closed curtain during power failure, and is practical.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that schematic diagram is formed in the grafting of Fig. 1 external threaded 5.
The contrast accompanying drawing is made an explanation to the utility model in conjunction with the embodiments below.
Embodiment, comprise motor 1, be fixedly connected on the decelerator 2 of motor 1 output shaft, the decompression rectification power of positive and negative rotation is provided to motor 1 by two-way switch control, one end is by the external threaded 5 of support 3 rests, the other end and reducer gear 4 interference fit and be mated the nut 6 of forming screw-and-nut mechanism, and the suspension ring 7 that link to each other with the little ring that is connected curtain.External threaded 5 is 15 millimeters by 3 diameters, length is that 500 millimeters external threaded monomer 11 is 4 millimeters through 4 diameters, length is that one is formed in 50 millimeters connecting axle 9 grafting, the two ends of screw rod monomer 11 are the semicylinder 8 of 20 millimeters of column lengths, 16 millimeters of blind hole 10 hole depths in axle center, under external threaded 5, be provided with the cramp bar 12 that is with suspension ring 7, distance bracket 3 ends suspension ring 13 farthest are fixed on the nut 6 through a gripper shoe 14, with the connecting axle of reducer gear 4 interference fit be provided be with on it rope 15 and be positioned at that a wire-drawing wheel 16 under it is combined into artificial drawing transmission mechanism draw wheel 17.
When opening two-way switch, civil power provides positive and negative rotary power source through the decompression rectification power that step-down rectifier provides to motor 1, it is moving that motor 1 drives reducer gear 4, make the 5 positive and negative rotations of coaxial external threaded, drive nut 6 on it along screw rod 5 move left and right, promote suspension ring 7 move left and right, thereby make curtain open/close freely.
Claims (1)
1, a kind of electrically driven curtain, comprise motor, be fixedly connected on the decelerator of motor output shaft, the decompression rectification power of positive and negative rotation is provided to motor by two-way switch control, one end is by the external threaded of support rest, the other end and reducer gear interference fit and be mated the nut of forming screw-and-nut mechanism, and the suspension ring that link to each other with the little ring that is connected curtain, it is characterized in that:
