The invention discloses an automatic temperature sensitive window closing device. The automatic temperature sensitive window closing device is arranged between the a window frame and a window sash andcomprises a device body, a supporting arm and an installation seat, wherein the device body comprises a guide rail, a sliding block slidably arranged inside the guide rail in the length direction ofthe guide rail, a driving component used for driving the sliding block to slide and a locking component used for limiting sliding of the sliding block relative to the guide rail, the locking componentcomprises a support arranged inside the sliding block, a blocking block penetrating through the sliding block and the guide rail in sequence and used for limiting the sliding of the sliding block relative to the guide rail and a temperature sensitive glass column arranged inside the sliding block, and the two ends of the temperature sensitive glass column are connected to the support and the blocking block in an abutted manner correspondingly. According to the automatic temperature sensitive window closing device, the sliding of the sliding block is limited by the arrangement of the blockingblock capable of penetrating through the sliding block and the guide rail at the same time, and the locking effect is good; meanwhile, the temperature sensitive glass column is arranged to sense temperature changes in the outside world, and when a fire disaster breaks out, rapid response can be performed to close a window; and the automatic temperature sensitive window closing device is simple instructure and low in cost.
Description
technical field [0001] The invention relates to an automatic temperature-sensing window closer. Background technique [0002] Window closers, which are mainly used for various movable fire windows, solve the problem that the movable fire windows cannot realize ventilation and lighting because they are usually closed. Existing window closers are generally divided into two types, one is an electric window closer, and the other is a movable window closer controlled by a mechanical principle. Its main function is reflected in two aspects: on the one hand, it can open and position the fire windows in a limited way to improve the ventilation and lighting effects; on the other hand, when a fire occurs, it can automatically close the windows to prevent the circulation of air to control the spread of fire. [0003] However, most of the existing window closers have complex structures and low sensitivity to temperature changes, and are prone to danger due to accidents in the event of...
