Abstract

The utility model discloses a skylight for daylighting and ventilation, which comprises a frame and a light-transmitting top surface and a light-transmitting facade connected to the frame. The movable window sash is connected with a rotatable transmission shaft and a push rod motor hinged on the frame, a crank arm and a connecting rod are fixedly connected to the transmission shaft, the other end of the crank arm is hinged with the push rod motor, and the other end of the connecting rod Hinged with the window sash, the push rod motor is controlled by the control circuit. The opening and closing of the window sash of the skylight is realized by pushing the crank arm driven by the push rod type motor to drive the action of the connecting rod. The skylight has simple structure, convenient and labor-saving opening and closing, and low manufacturing cost.

Description

Lighting and ventilation skylight

technical field

The utility model relates to a daylighting and ventilation skylight.

Background technique

At present, skylights are arranged on the roofs of many workshops in factories, some skylights are only used for ventilation, and some skylights are used for both ventilation and lighting. The above-mentioned skylight basically has a top surface and four facades connected with the top surface. There are movable sash on the facade, and the opening and closing of the sash is realized by manual operation of the mechanical window opening mechanism connected to the sash. The opening and closing of this kind of skylight is relatively laborious, and the structure of the window opening mechanism is complicated, which increases the manufacturing cost of the whole skylight.

Utility model content

The technical problem to be solved by the utility model is to provide a daylighting and ventilation skylight with simple structure, low manufacturing cost, convenient and labor-saving opening and closing.

In order to solve the above-mentioned technical problems, the skylight for daylighting and ventilation of the utility model includes a framework and a light-transmitting top surface and a light-transmitting facade connected to the framework. The top surface and the facade are connected to form a room body. There is a movable window sash, and its structural characteristics are: the frame is connected with a rotatable transmission shaft and a push rod motor, the transmission shaft is fixed with a crank arm and a connecting rod, and the other end of the crank arm is connected with the push rod. A type motor is hinged, the other end of the connecting rod is hinged with the window sash, and the push rod type motor is controlled by a control circuit.

When opening the window, the push rod motor signal is given through the control circuit, and the push rod motor starts to close the rod, thereby driving the crank arm to rotate, the crank arm rotates to drive the transmission shaft to rotate, the transmission shaft drives the connecting rod to rotate, and the connecting rod pushes the movable window sash upward. To open the window; when the window needs to be closed, give the push rod motor a signal, and the push rod motor starts to extend the rod and drive the crank arm to rotate in reverse, and the reverse rotating crank arm drives the drive shaft to reverse, thereby driving the connecting rod Pull down the movable sash to achieve the purpose of closing the window. It is not difficult to see from the opening and closing process of the above-mentioned window sash that the daylighting and ventilation skylight with the above-mentioned structure has a simple structure, low manufacturing cost, and convenient and labor-saving opening and closing.

After the sash switch is in place, the push rod motor may burn out due to overload due to improper operation. Upper limiter and lower limiter. When the window sash is opened to the maximum, the limit arm touches the upper limiter at the same time, and the push rod motor automatically powers off and stops working; when the window sash is closed tightly, the limit arm contacts the lower limiter at the same time, and the push rod motor automatically powers off and stops working .
