Abstract

A folding arm type automatic window opener, including a casing, a DC motor is arranged in the casing, and a worm is connected to the power output end of the DC motor; a worm wheel is installed on the casing, and a folding arm is fixed on the worm wheel. The worm gear and worm mentioned above are meshed. When working, the DC motor rotates to drive the worm to rotate through the reduction box. When the worm rotates, it drives the worm gear to rotate, so that the folding arm is lifted up or down, thereby driving the window switch. This product has a simple structure and can be modularized to save costs. Installation, commissioning and maintenance are very simple, and it can realize the opening and closing of casement windows at any angle.

Description

A folding arm type automatic window opener

technical field

The utility model relates to the technical field of window openers, in particular to a folding arm type automatic window opener.

Background technique

With the development of science and technology and the advent of the intelligent era, it is difficult for people to open and close the windows of large buildings, stadiums, entertainment venues and homes when they are too high, and due to the requirements of fire and smoke exhaust, the opening angle of the opening fan is required to be as large as possible , so as to meet the fire smoke exhaust area requirements of the building. Traditional casement windows use oblique chain or rack type electric window drives to realize the opening and closing of the opening fan, which is costly, complicated in structure, limited by space during installation, and separate design of electric drive is required for casement windows of different sizes. The window opener cannot achieve standardized production, and at the same time cannot realize the opening of the casement window at a large angle, and cannot meet the smoke exhaust area requirements.

Contents of the invention

The utility model discloses a folding arm type automatic window opener, which is suitable for casement windows and realizes the automatic opening and closing of the windows through electric control.

The technical solution adopted by the utility model: a folding arm type automatic window opener, including a casing, a DC motor is arranged in the casing, and a worm is connected to the power output end of the DC motor; a worm wheel is installed on the casing, A folding arm is fixed on the worm wheel, and the worm wheel and the worm are meshed. When working, the DC motor rotates to drive the worm to rotate through the reduction box. When the worm rotates, it drives the worm gear to rotate, so that the folding arm is lifted up or down, thereby driving the window switch.

The beneficial effects of the utility model: the folding arm type automatic window opener can be applied to translational windows of different sizes, the installation is not limited by space, the electric control is more convenient and the degree of automation is higher. The cost is low, the structure is simple, standardized production can be realized, installation, commissioning and maintenance are very convenient, and it can be opened at any angle.

Fig. 1 is a structural representation of the utility model;

Among the figure, 1, casing, 2, worm, 3, worm gear, 4, reduction box, 5, DC motor, 6, folding arm.

Detailed ways

A kind of folding arm type automatic window opener as shown in Figure 1, comprises casing 1, is provided with DC motor 5 in casing 1, and the power output end of DC motor 5 is connected with a worm screw 2; On described casing 1 A worm wheel 3 is installed, and a folding arm 6 is fixed on the worm wheel 3, and the worm wheel 3 and the worm screw 2 are engaged.

Among them, the power output end of the DC motor 5 is connected to the worm 2 through a reducer 4, and the casing 1 adopts an aluminum alloy casing, half of the worm wheel 3 is inside the casing 1, and the other half is outside the casing 1, and the folding arm 6 One end is fixed on the part of the worm wheel 3 outside the casing 1.

When working, install the folding arm type automatic window opener on one side of the casement window, start the DC motor 5, the power output end of the DC motor 5 drives the worm 2 to rotate through the reduction box 4, and when the worm 2 rotates, it drives the worm gear 3 to rotate, so that Folding arm 6 lifts upwards or falls downwards, thereby drives window switch, when casement window drives to a certain position, controls DC motor 5 to stop rotating, and folding arm 6 stops moving, and window is fixed on current position.
