Description

Technical Field

[0001] The invention relates to the technical field of building hardware, and in particular to a non-sensing fireproof window closing device. Background Art

[0002] For building doors and windows, fireproof windows play an important role in preventing major losses when a fire occurs, slowing the spread of fire, including open flames, high temperatures, and thick smoke, and buying time for fire rescue. Many buildings have windows installed with ordinary hinges, and do not have fireproof automatic window closing function components; after the existing fireproof automatic window closing components on the market are installed, there is resistance to opening the window, and the elderly and children need a lot of effort to open the window. For windows installed with ordinary hinges, there must be no resistance when opening the window, and fireproof window components need to be installed. Therefore, a set of fireproof windows with no resistance to opening the window and automatic window closing function components are designed, which can adapt to a variety of windows with ordinary hinges. There is no resistance when opening the window normally, and the window can be closed automatically when a fire occurs. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a novel and reliable fireproof window closing device which can realize the fireproof self-closing function.

[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is: a non-sensing fireproof window closing device, including a hinge and a reset mechanism, the reset mechanism including a slide rail, a first slider slidably connected to the slide rail, a tube, a second slider slidably connected to the tube, the tube is provided with a guide groove extending along the length direction of the tube, the side of the second slider is formed with a first protrusion extending outside the guide groove and slidingly cooperating with the guide groove, a connecting shaft is connected between the second slider and the first slider, and a reset unit for driving the connecting shaft to contract is arranged in the tube, the tube is provided with a second protrusion on the side on the same side as the contraction direction of the connecting shaft, a safety bolt and a fireproof explosion bead for positioning the first protrusion are arranged between the second protrusion and the first protrusion, the first slider is connected to the hinge, and when the connecting shaft contracts, the first slider drives the hinge to close.

[0005] The beneficial effect of the present invention is that the reset mechanism of the fireproof window closing device of the present invention can drive the hinge to close when encountering a high temperature disaster such as a fire, thereby realizing the fireproof self-closing function. Specifically, when encountering a fire, the fireproof explosion bead will split, and at this time the safety bolt loses the supporting effect of the fireproof explosion bead, and the positioning effect of the safety bolt falling on the first protrusion disappears. At this time, the connecting shaft can shrink under the action of the reset unit and drive the first slider to slide, and finally drive the hinge to close to realize its fireproof self-closing function.

[0006] Preferably, the hinge includes a fan connector, a frame connector, a first connecting rod, a second connecting rod and a third connecting rod, wherein one end of the first connecting rod is provided with a first sliding groove, the first slider is pivoted to the first connecting rod, and the pivot between the first slider and the first connecting rod is slidably matched with the first sliding groove, the middle part of the fan connector is provided with a second sliding groove, the second connecting rod, the first connecting rod and the fan connector are pivoted at the same time, and the pivot between the second connecting rod, the first connecting rod and the fan connector is slidably matched with the second sliding groove, the frame connector is provided with a third sliding groove, the third connecting rod is provided with three pivot points, which are respectively pivoted to the fan connector, the second connecting rod and the frame connector, and the pivot between the third connecting rod and the frame connector is slidably matched with the third sliding groove. When the first connecting rod is driven by the first slider, it can simultaneously drive the fan connector, the frame connector, the second connecting rod and the third connecting rod to swing, thereby driving the hinge to close and realizing the fire-proof self-closing function.

[0007] Preferably, the connecting shaft is provided with a connecting head at one end on the same side as the first slider, and the first slider has a connecting groove for matching the connecting head. The connecting groove and the connecting head are connected to each other to achieve a simple connection between the connecting shaft and the first slider.

[0008] Preferably, the second slider is connected to the first protrusion by screws. The above structure can realize a detachable connection between the second slider and the first protrusion, which is convenient for installation and connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution claimed by the present invention will now be further described in detail with reference to the accompanying drawings and specific embodiments.

[0015] See also Figures 1 to 4 As shown, a non-contact fireproof window closing device in this embodiment includes a hinge 1 and a reset mechanism 2.

[0016] The reset mechanism 2 includes a slide rail 21, a first slider 22 slidably connected to the slide rail 21, a tube 23, a second slider 24 slidably connected to the tube 23, and the tube 23 is provided with a guide groove 231 extending along the length direction of the tube 23. The side of the second slider 24 is formed with a first protrusion 241 extending outside the guide groove 231 and slidingly matching with the guide groove 231. Specifically, the second slider 24 is connected to the first protrusion 241 by a screw. A connecting shaft 25 is connected between the second slider 24 and the first slider 22. Specifically, the connecting shaft 25 is provided with a connector 251 at one end on the same side of the first slider 22, and the first slider 22 is provided with a connecting groove matching the connector 251.

[0017] At the same time, a reset unit 26 for driving the connecting shaft 25 to retract is provided in the tube 23, and a second protrusion 27 is provided on the side of the tube 23 on the same side as the retraction direction of the connecting shaft 25. A safety bolt 28 and a fireproof bead 29 for positioning the first protrusion 241 are provided between the second protrusion 27 and the first protrusion 241. The first slider 22 is connected to the hinge 1, and when the connecting shaft 25 retracts, the first slider 22 drives the hinge 1 to close.

[0018] In this embodiment, the hinge 1 includes a fan connector 11, a frame connector 12, a first connecting rod 13, a second connecting rod 14 and a third connecting rod 15, wherein a first sliding groove 131 is provided at one end of the first connecting rod 13, the first slider 22 is pivoted to the first connecting rod 13, and the pivot between the first slider 22 and the first connecting rod 13 slides with the first sliding groove 131; a second sliding groove 111 is provided in the middle of the fan connector 11, the second connecting rod 14, the first connecting rod 13 and the fan connector 11 are pivoted at the same time, and the pivot between the second connecting rod 14, the first connecting rod 13 and the fan connector 11 slides with the second sliding groove 111; the frame connector 12 is provided with a third sliding groove 121; the third connecting rod 15 has three pivot points that are respectively pivoted to the fan connector 11, the second connecting rod 14 and the frame connector 12, and the pivot between the third connector and the frame connector 12 slides with the third sliding groove 121.

[0019] The working principle of the fireproof window closing device in this embodiment is as follows:
