The utility model aims at overcoming the not enough of prior art, provide a location winding device, prevent around, when putting the rope that the stay cord winding is in disorder.
The purpose of the utility model is realized like this: a positioning winding device is used for winding and unwinding a pull rope and comprises a fixed frame, wherein one side of the fixed frame is connected with a fixed wheel, and the fixed wheel is provided with an internal thread; the other side of the fixed frame is connected with a motor, an output shaft of the motor is connected with a sliding shaft, the sliding shaft penetrates through the fixed frame and is arranged in the fixed frame, a clamping key is axially connected to the sliding shaft, the sliding shaft is connected with a synchronous wire wheel through the clamping key, one end of the synchronous wire wheel is integrally provided with a connector, the connector is provided with external threads and is in threaded connection with the fixed wheel, and the outer surface of the synchronous wire wheel is provided with a spiral wire groove; the fixing frame is further connected with a wire holder, one end of the pull rope is fixed on the synchronous wire wheel, and the pull rope penetrates through the fixing frame and the wire holder.
Through the design, the motor works to drive the sliding shaft to rotate and drive the synchronous wire wheel to rotate, and the synchronous wire wheel is in threaded connection with the fixed wheel through the connector, so that the synchronous wire wheel axially moves on the sliding shaft, namely the synchronous wire wheel axially moves along with the increase or decrease of the stay cord when the stay cord is wound and unwound, thereby avoiding the stay cord from being wound and disordered and avoiding the synchronous wire wheel from being wound and locked; and the torque variation caused by mutual overlapping of the pull ropes during rope winding can not be caused, so that the constant torque output by the equipment is ensured.
In order to facilitate installation, the section of the fixing frame is rectangular with an opening at one end, the fixing frame comprises two sections of shaft installation plates and a section of wiring installation plate, the two sections of shaft installation plates are arranged in parallel, and the two sections of shaft installation plates are connected into a whole through the wiring installation plate; the shaft mounting plate is provided with shaft holes, the sliding shaft penetrates through one of the shaft holes, and the connector of the synchronous wire wheel penetrates through the other shaft hole; the wiring mounting plate is provided with a rope hole, and the stay rope passes through the wire holder and the rope hole on the wiring mounting plate.
The utility model discloses a motor is brushless motor.
In order to make the structure more reasonable, reduce the volume, the tight pulley is connected in the outside one side of mount, the opposite side at the mount outside is connected to the motor.
