Novel dynamoelectric concealed mesh window

Abstract

The present invention relates to a novel electric invisible gauze, including a rolling screen cylinder, gauze and a frame. The rolling screen cylinder is arranged at one end of two frames. The end of the gauze arranged at outside of the rolling screen cylinder is fixed with a horizontal pull rod. The other end of the two frames is provided with an electric rolling device including an external housing and a rolling tube in the external housing. The two ends of the rolling tube are rolled with a pull rod respectively. The two pull rods are arranged at the external side of the two frames and connected with the two ends of the horizontal pull rod respectively. The novel electric invisible gauze does not affect the appearance of the window after installation, and has the advantage of simple structure, convenient assembly, reliable use, smooth operation on the gauze and keeping the smooth condition.

Description

technical field [0001] The invention relates to an electric invisible screen window which is driven by a motor to open and close. Background technique [0002] The invisible screen window generally used at present is made up of roller shade cylinder, the gauze that can be crimped in the roller shade cylinder, and the frame that is positioned at its two sides and has chute. The roller shutter tube is installed on the top of the window, the frame is installed on both sides of the window, and the frame is also provided with a draw-in slot communicated with the chute. A tie rod is fixed on the end of the gauze outside the roller blind tube, and the two ends of the tie rod are located in the chute of the two frames. When the screen window is in the open state, the gauze net is curled in the roller blind tube. When the screen window needs to be closed, the tie rod is pulled down by hand to the bottom of the window, and the tie rod is clamped in the slot on the frame. And when th...

Problems solved by technology

Among them, the patent No. 95210598.5 of the electric screen window uses a micro-motor to drive the gauze net movement, unless a motor with a larger power is used, but this will increase the volume of the motor and is difficult to be accepted by users.

And the biggest problem of this technical solution is that the gauze is tightened by two pull wires to ensure its smoothness during operation. As the roll-up rod rolls up the gauze, its diameter becomes larger and larger, so every time the roll-up rod rotates, the running distance of the gauze will not be consistent with the length of the pull wire, which will cause the gauze to be too tight to Roll up, or the gauze will lose the tension of the pull wire and become loose and uneven

Although the electric screen window with the patent number 200520043197.3 overcomes this defect, its structure is too complicated, and the many parts will make the use of the electric screen window prone to failure and affect the use of users
