Detailed Description

The claimed invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 6, the fire window closing apparatus in the present embodiment includes a swing link 3, and a first assembly 1 and a second assembly 2 hinged to two ends of the swing link 3, respectively, where the first assembly 1 and the second assembly 2 are further connected to a window sash and a window frame, respectively.

The first component 1 comprises a base 11, a first sliding block 12 in interactive fit with the base 11, and a temperature-controlled window closing mechanism for driving the first sliding block 12 to slide. The first slider 12 is formed with a rack 121, and the end of the swing link 3 is formed with a gear 31 engaged with the first slider 12. The temperature control window closing mechanism comprises a temperature sensing unit 131, a second sliding block 132, a positioning hook 133, an adjusting screw 136, a positioning sliding block 134 and a resetting unit 135.

An inner cavity for accommodating the temperature sensing unit 131 and the positioning slider 134 is reserved inside the second slider 132, in this embodiment, a discharge hole 1321 for the temperature sensing unit 131 to pass through is formed in the side portion or the bottom portion of the second slider 132, and the discharge hole 1321 can discharge fragments of the burst temperature sensing unit 131, so that the positioning slider 134 can freely slide to ensure that the window sash can be smoothly closed when encountering fire.

The positioning hook 133 is pivoted with the second slider 132, a fastening groove 111 which is matched and fastened with the positioning hook 133 is formed in the side portion of the base 11, the positioning slider 134 is arranged between the positioning hook 133 and the temperature sensing unit 131, the adjusting screw 136 is in threaded connection with the end portion of the second slider 132 and presses against the end portion of the temperature sensing unit 131, and the pressing pressure of the adjusting screw 136 on the temperature sensing unit 131 can be adjusted by screwing the adjusting screw 136, so that the temperature sensing unit 131 is limited to the positioning slider 134.

The positioning sliding block 134 abuts against the positioning hook 133 to keep the positioning hook 133 fastened to the fastening groove 111, and the reset unit 135 is configured to drive the second sliding block 132 to push the first sliding block 12. In this embodiment, the reset unit 135 is a spring, a third slider 14 is further disposed between the second slider 132 and the reset unit 135, and the third slider 14 is in sliding fit with the base 11.

The working principle of the invention is as follows:

under the normal state, the temperature sensing unit 131 will be limited to the positioning sliding block 134, so that the positioning sliding block 134 cannot slide and is kept in contact with the positioning hook 133, the positioning hook 133 cannot move and is kept fastened with the fastening groove 111, and at this time, the position of the second sliding block 132 on the base 11 is fixed and cannot generate thrust to the first sliding block 12.

When fire occurs, the temperature sensing unit 131 is burst by high temperature, the limiting effect on the positioning sliding block 134 after the temperature sensing unit 131 bursts is eliminated, the positioning sliding block 134 can slide freely at the moment and does not interfere with the positioning hook 133, the positioning hook 133 can rotate freely to be disengaged from the catching groove 111, and the second sliding block 132 is driven by the reset unit 135 to move so as to push the first sliding block 12. Because the first sliding block 12 is formed with the rack 121, when the rack 121 and the first sliding block 12 move synchronously, the rack 121 drives the gear 31 to rotate, and finally drives the swing rod 3 to swing along the closing direction of the window sash, so that the window sash is closed to realize the function of fire prevention self-closing.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to limit the present invention in any way. Those skilled in the art can make many changes and modifications to the disclosed embodiments, or modify equivalent embodiments to practice the disclosed embodiments, without departing from the scope of the disclosed embodiments.
