Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 5, the present invention discloses a fireproof window closer, which comprises a fixing frame 10, a telescopic arm 20 and a temperature-sensitive elastic component. One end of the telescopic arm 20 is coupled to the fixed frame 10, and the other end of the telescopic arm 20 is a telescopic end. The temperature-sensing elastic component comprises an elastic restoring element 32, a temperature-sensing element 33, a sliding rail 3630 and a sliding block 31. The slider 31 is disposed in cooperation with the sliding rail 3630, and the slider 31 can move along the sliding rail 3630. One end of the slider 31 is coupled to the telescopic end, and an elastic restoring element 32 is disposed between the other end of the slider 31 and the sliding rail 3630. The slide rail 3630 is provided with a limiting groove 301, the slide block 31 is provided with a locking piece 34 matched with the limiting groove 301, one end of the temperature sensing element 33 is abutted against the slide block 31, and the other end of the temperature sensing element is abutted against the locking piece 34 so that the locking piece 34 is clamped with the limiting groove 301. The slide rail 3630 is provided with a mounting hole 302.

When the temperature sensing element 33 bursts, the locking piece 34 is separated from the limiting groove 301, and the elastic restoring element 32 pulls the sliding block 31 to move.

When in use, the fixed mount 10 is fixed with the window sash, and the slide rail 3630 is fixed with the window frame. Under the normal condition that a fire disaster does not happen, the temperature sensing element 33 is not broken, and then the locking piece 34 is clamped in the limiting groove 301. And when the window sash is opened, the telescopic arm 20 is extended or shortened. When a fire breaks, the temperature sensing element 33 is broken, the locking fastener 34 loses the acting force of the temperature sensing element 33 on the temperature sensing element, and then under the action of the elastic restoring element 32, the sliding block 31 moves along the sliding rail 3630, and the whole telescopic arm 20 is pulled, so that the window is closed.

The locking member 34 includes a limiting protrusion 341 and an adjusting plate 343, the limiting protrusion 341 is located at the lower side of the adjusting plate 343 and is clamped with the limiting groove 301, a protrusion 311 is disposed on the slider 31, and the adjusting plate 343 is sleeved on the protrusion 311. The connection between the elastic restoring element 32 and the slider 31 is provided with a pull ring, which is sleeved on the protrusion 311 and located at the lower side of the adjusting plate 343. In the absence of a fire, the resilient return element 32 is always in tension and the entire temperature-sensitive elastic assembly is in a balanced and stable condition. Once the temperature sensing element 33 is broken, the original balance state is broken, namely the elastic restoring element 32 pulls the pull ring, the pull ring drives the slide block 31, and the slide block 31 pulls the telescopic arm 20 to move integrally, thereby realizing the window closing. As shown in fig. 2, due to the presence of the pull ring, the right end of the adjustment plate 343 tilts, due to the action of the temperature-sensitive element 33, the left end of the adjustment plate 343 presses downward, once the temperature-sensitive element 33 is damaged, the right end of the pull ring is stressed under the action of the elastic restoring element 32, the left end of the pull ring tilts upward, the temperature-sensitive element 33 is broken, the left end of the locking piece 34 tilts upward under the action of the pull ring, the limiting protrusion 341 is separated from the limiting groove 301, and thus the elastic restoring element 32 can pull the slider 31 to move.

The temperature sensing element 33 is disposed obliquely relative to the sliding rail 3630 to apply an urging force to the locking member 34, and the urging force presses the position-limiting protrusion 341 into the position-limiting groove 301.

A threaded hole is formed in the boss 311, a close-looking screw 35 is arranged in the threaded hole in a matching manner, and the close-looking screw 35 is arranged in parallel to the slide rail 3630. A stopper 342 is disposed on the upper side of the adjusting plate 343. The temperature sensing element 33 is located between the stopper 342 and the staring screw 35. The set of the staring screw 35 is for ease of installation.

The telescopic boom 20 comprises a main boom 21, an auxiliary boom 22 and a riveting assembly, the riveting assembly comprises a rigid gasket 26, a first friction gasket 24, a second friction gasket 25 and a rivet 23, a groove body 211 is formed in the main boom 21 in a penetrating mode, the rigid gasket 26 is located on the upper side of the main boom 21, the rigid gasket 26 is riveted with the auxiliary boom 22 through the rivet 23, the rivet 23 is arranged in the groove body 211 in a penetrating mode, the first friction gasket 24 is arranged between the main boom 21 and the auxiliary boom 22, and the second friction gasket 25 is arranged between the main boom 21 and the rigid gasket 26. The first friction pad 24 and the second friction pad 25 are nylon pads. The auxiliary arm 22 is pulled to move relative to the main arm 21, and due to the effect of the riveting component, the sash is manually pushed by a person, and the telescopic arm 20 can extend or shorten, so that the sash can be stopped at any angle between 20 and 90 degrees. The first friction pad 24 and the second friction pad 25 increase the friction between the main arm 21 and the sub-arm 22, thereby facilitating the window sash to be parked. The telescopic arm 20 is convenient for opening and closing the window sash.

The rigid gasket 26 is a stainless steel gasket. The temperature sensing element 33 is a temperature sensing glass ball. The resilient return element 32 is a tension spring.
