Description

Technical Field

[0001] The utility model relates to the technical field of fireproof windows, in particular to a fireproof window which can be closed automatically. Background Art

[0002] Fireproof windows refer to windows that can isolate and prevent the spread of fire. They are generally composed of steel window frames, steel window sashes, and fireproof glass. As an important fire prevention device, fireproof windows can be seen everywhere in various buildings. They can effectively improve the fire resistance of buildings and provide protection for people's lives and property. There are some fireproof windows that can be closed automatically. This type of fireproof window is generally blocked by a latch. The latch is supported by a temperature sensor. When the temperature is higher than the temperature that the temperature sensor can withstand, the temperature sensor is damaged and the latch is withdrawn, and the fireproof window sash falls. In this setting, the fireproof window sash falls rapidly, which is easy to cause damage to the fireproof window frame and the fireproof window sash. In severe cases, the glass of the fireproof window is shattered, which seriously affects the fireproof performance of the fireproof window. For this reason, we propose a fireproof window that can be closed automatically. Utility Model Content

[0011] Beneficial Effects

[0012] The utility model provides a fireproof window that can be closed automatically. It has the following beneficial effects:

[0013] (1) The automatically closing fireproof window, when in normal use, flips open the window panel so that the support rod is stuck under the protrusion to limit the window panel. When a fire occurs, the smoke sensor senses the smoke and sounds an alarm, causing the rotating motor to wrap around the connecting steel cable, which pulls the support rod, and the support rod returns to the inside of the groove. The window panel begins to move back due to its own gravity, so that the window panel is closed. When the window panel begins to swing, the side of the window panel hits the position of the buffer rod and the buffer rubber block. After being hit, the buffer rod swings through the rotating column. The swing of the rotating column is affected by the torsion of the torsion spring, thereby buffering the impact force of the window panel. When the buffer rod swings to a vertical position, the side of the window panel contacts the side of the buffer rubber block, and the side of the buffer rubber block contacts the side of the third mounting cavity to squeeze the buffer rubber block, thereby reducing the vibration generated during the impact and avoiding the situation where the movable fan falls and causes the glass to be shattered.

[0014] (2) For the automatically closing fireproof window, when the window panel swings, it drives the adapter iron block to enter the fourth installation cavity and hit the magnetic block. The magnetic block hits the spring, and the magnetic block absorbs the adapter iron block while providing a buffering force to keep the window panel closed. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A first adapting cavity 4 is provided on one side of the window panel 3 corresponding to the second adapting cavity 6, and a protrusion 5 is fixedly connected equidistantly inside the first adapting cavity 4. The protrusion 5 consists of a right-angled triangle block and a trapezoidal block. The right-angled side of the right-angled triangle block on the protrusion 5 is fixedly connected to the side of the first adapting cavity 4, and the trapezoidal block on the protrusion 5 is fixedly connected to the hypotenuse of the right-angled triangle block on the protrusion 5. An oblique angle is provided on the upper end of the support rod 7, and the driving structure includes a rotating motor 10 fixedly connected to the side of the window frame 1. A groove 8 is provided on the side of the second adapting cavity 6 corresponding to the position of the support rod 7, and the groove 8 passes through the wall of the window frame 1, and a connecting steel cable 9 is wound around the output end of the rotating motor 10. The end of the connecting steel cable 9 away from the rotating motor 10 passes through the groove 8 and is fixedly connected to the side of the support rod 7.

[0029] The buffer structure includes a second mounting cavity 11 opened on the side of the first mounting cavity 2, the second mounting cavity 11 has two and symmetrically distributed on the side of the first mounting cavity 2, the inner side of the second mounting cavity 11 is rotatably connected with a rotating column 12 through a torsion spring, the side of the rotating column 12 is fixedly connected with a buffer rod 13, the buffer rod 13 is a rectangular block, the upper side of the second mounting cavity 11 is opened with a third mounting cavity 14, the third mounting cavity 14 is a rectangular cavity, the upper side of the buffer rod 13 is fixedly connected with a buffer rubber block 15 corresponding to the position of the third mounting cavity 14, the inner bottom side of the window frame 1 is opened with a fourth mounting cavity 16, the fourth mounting cavity 16 is a rectangular cavity, the side of the window panel 3 is fixedly connected with an adapting iron block 19 corresponding to the position of the fourth mounting cavity 16, the side of the fourth mounting cavity 16 is fixedly connected with a spring 17, and one end of the spring 17 corresponding to the adapting iron block 19 is fixedly connected with a magnetic block 18,

[0031] The working principle of this utility model:

[0032] When in use, the window panel 3 is flipped open during normal use, and the support rod 7 is swung to allow the support rod 7 to enter the first adapter cavity 4 and be stuck under the protrusion 5 for limiting. When a fire occurs, the smoke sensor 20 senses the smoke and sounds an alarm, causing the rotating motor 10 to start moving. The rotating motor 10 winds the connecting steel cable 9, and the connecting steel cable 9 pulls the support rod 7, and the support rod 7 moves on the protrusion 5. When the support rod 7 leaves the protrusion 5, the window panel 3 starts to move back due to its own gravity, so that the window panel 3 is closed. When the door panel 3 starts to swing, the side of the window panel 3 hits the position of the buffer rod 13 and the buffer rubber block 15. After the buffer rod 13 is hit, it swings through the rotating column 12. The swing of the rotating column 12 is affected by the torsion of the torsion spring, thereby buffering the impact force of the window panel 3. While swinging, the window panel 3 drives the adapter iron block 19 to enter the fourth installation cavity 16 to hit the magnetic block 18. The magnetic block 18 hits the spring 17. While buffering, the magnetic block 18 adsorbs the adapter iron block 19 to maintain the stability of the window panel 3 during the closing process.
