Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
The first embodiment is as follows: referring to fig. 1-3, an electric lifting curtain for movies comprises a shell 1, wherein a motor 2 is fixedly connected to the right side of the shell 1, a driving rotating shaft 3 is fixedly connected to the output end of the motor 2, a curtain 4 is wound on the outer side of the driving rotating shaft 3, a through slot 5 is formed in the bottom of the shell 1, and the curtain 4 penetrates through the through slot 5 and is connected with a counterweight rod 6;
when the curtain is used, the motor 2 is started, the motor 2 can drive the driving rotating shaft 3 to rotate forward and backward by rotating forward and backward, and then the curtain is electrically lifted under the action of the counterweight rod 6;
the left end of the driving rotating shaft 3 penetrates through the shell 1 to be connected with a rotating disc 7, the right side of the rotating disc 7 is fixedly connected with an arc-shaped inclined top block 8, the front side of the shell 1 is connected with a horizontal sliding rod 9 in a sliding mode, the left end of the horizontal sliding rod 9 is matched with the arc-shaped inclined top block 8, the right end of the front side of the shell 1 is fixedly connected with a positioning electromagnet 10, the positioning electromagnet 10 is matched with the horizontal sliding rod 9 in an attracting mode, a spring 11 is fixedly connected between the positioning electromagnet 10 and the horizontal sliding rod 9, bristles 12 are fixedly connected below the horizontal sliding rod 9, and the bristles 12 are;
the motor 2 rotates to drive the rotating disc 7 to rotate, the rotating disc 7 can drive the horizontal sliding rod 9 to move left and right, the horizontal sliding rod 9 can move left and right to clean the curtain, the spring 11 provides the reset force of the horizontal sliding rod 9, when the motor 2 rotates reversely to pack the curtain, the arc-shaped inclined top block 8 interferes with the horizontal sliding rod 9, the positioning electromagnet 10 is turned on at the moment, the positioning electromagnet 10 overcomes the spring force of the spring 11 to suck the horizontal sliding rod 9, and therefore interference is avoided.
