Example 2
With reference to fig. 5 to 8, the structure and principle of the present embodiment are substantially the same as those of embodiment 1, and the same points are not described again, except that: the opening and closing control device 1 of the door and window comprises a swinging piece 900, wherein the swinging piece 900 is pivoted on a fixed seat 100, the swinging piece 900 is provided with a supporting rod 901 and a clamping hook 902 which are opposite, the clamping hook 902 is suitable for clamping a free end 2022, and the supporting rod 901 and the fixed seat 100 jointly define a clamping groove 800 which is suitable for clamping a heat sensitive element 600; when the heat sensitive element 600 deforms, the supporting rod 901 loses the supporting force and swings, so that the hook 902 swings to release the free end 2022, and the free end 2022 drives the elastic element 400 to return to drive the movable element 200 to move relative to the fixed seat 100, so that the rocker arm 300 rotates to close the door and window sash.
That is, the fixing seat 100 is disposed on a frame or a sash of a door or a window, and one end of the rocker 300 is connected to the sash or the frame, so that when a person operates a sash switch, the rocker 300 can rotate and drive the movable member 200 to move relative to the fixing seat 100 through cooperation of the gear structure 301 and the rack 201, so that the elastic element 400 is compressed or returned. At the position of the thermal sensor 600, the thermal sensor 600 is clamped in the clamping groove 800, one end of the thermal sensor is abutted against the fixed seat 100, and the other end of the thermal sensor is abutted against the supporting rod 901, so that the supporting rod 901 is kept in a vertical state, the swinging is avoided, and the clamping hook 902 can be clamped with the free end of the extension rod 202; thus, when the heat sensitive element 600 deforms, the support rod 901 swings downward when losing the supporting force, and further drives the hook 902 to swing upward, so that the hook 902 releases the clamping connection with the free end 2022.
The free end 2022 of the extension rod 202 may be provided with a necking portion 2023 that is radially necked down, so that the hook 902 is clamped at the necking portion 2023 and is clamped with the free end 2022.
Therefore, through the arrangement of the swinging piece 900 and the installation mode of the elastic element 400, when the heat sensitive element 600 is clamped in the clamping groove 800, the door and window sash is opened, the rocker arm 300 drives the moving piece 200 to move relative to the fixed seat 100, so that the elastic element 400 is compressed, the elastic force acts on the swinging piece 900 through the extension rod 202, the elastic force is prevented from acting on the heat sensitive element 600, the bearing capacity of the heat sensitive element 600 is reduced, and the stability and the service cycle of the heat sensitive element 600 are further improved; when the heat sensitive element 600 deforms, the support rod 901 swings when losing the supporting force, so as to drive the hook 902 to swing and release the free end 2022 of the extension rod 202, the elastic element 400 loses the limitation and returns to the original position, so that the extension rod 202 moves and further drives the movable part 200 to move, the rocker arm 300 rotates to close the door and window sash, the normal ventilation and lighting performance of the door and window device is ensured, and the door and window sash can be closed in time under the fire state to isolate the fire.
In some examples, the card slot 800 has a positioning hole 9011 disposed on the support 901 and an adjusting screw 102 disposed on the fixing base 100, and the adjusting screw 102 locks the heat sensitive element 600 in the positioning hole 9011 to clip the heat sensitive element 600 in the card slot 800. It can be understood that one end of the thermal sensor 600 can pass through the positioning hole 9011 and be locked to the other end of the thermal sensor 600 by the adjusting screw 102, so that the thermal sensor 600 is clamped in the clamping groove 800. Thus, when the temperature is higher than the preset temperature, the heat sensitive element 600 deforms to release the supporting force for the supporting rod 901, and the heat sensitive element 600 may be a temperature sensitive glass ball or a fusible metal part. When a fire breaks out, the temperature-sensitive glass ball or the fusible metal part can sense the temperature, and when the temperature is higher than a preset temperature, the glass ball or the fusible metal part can explode or melt, so that the support rod 901 loses the supporting force to swing, and the hook 902 also swings to release the free end 2022.
