Description

Fusing triggering type outward-opening lower-suspension smoke exhaust window

Technical Field

The utility model relates to a fusing triggers formula and hangs smoke exhaust window under outwards opening.

Background

The smoke is one of the important reasons for casualties in a fire, so that the state requires smoke exhaust windows to be arranged in certain spaces, and the smoke can be timely exhausted after the fire happens to prolong the time for people to evacuate. The prior smoke exhaust window is commonly provided with a manual smoke exhaust window and an electric smoke exhaust window. The manual smoke exhaust window is not attractive due to the fact that the connecting rod needs to be arranged, and after a fire disaster happens, if no person operates the manual smoke exhaust window, the manual smoke exhaust window cannot play a smoke exhaust role. The electric smoke exhaust window is electrically controlled, as shown in Chinese patent with the patent number of 201922082336.8, the cost is high, and control components are complex and are prone to failure.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the above-mentioned not enough that exists among the prior art, and provide a fusing that structural design is reasonable, with low costs, the reliability is high, not fragile, automatic opening triggers formula and outwards opens and hangs down smoke exhaust window.

The utility model provides a technical scheme that above-mentioned problem adopted is: a fusing triggering type outward-opening downward-hanging smoke exhaust window comprises a window frame, hinges and window sashes; the bottom of the window sash is rotatably arranged at the bottom of the window frame through a hinge; the method is characterized in that: the device also comprises a rolling shaft, a spring, a fuse link and a steel cable; the fusing piece is fixed on the window sash and the window frame, and the window sash and the window frame are fixed together through the fusing piece; the spring is fixed between the window sash and the window frame 1, one end of the spring is connected with the window frame, the other end of the spring is connected with the window sash, and the spring is arranged in a compressed mode; the rolling shaft is rotatably arranged on the window frame; the steel cable is wound on the rolling shaft and is fixedly connected with the top of the window sash.

The fuse link pass through the bolt fastening at the top of casement and the top of window frame.

The utility model discloses all fixedly between fuse-link and window frame, between fuse-link and the last casement being provided with the rubber heat insulating mattress.

The roller bearing level set up.

Compared with the prior art, the utility model, have following advantage and effect: the utility model discloses can trigger the fusing through the temperature of flue gas when the conflagration takes place, open automatically under the effect of spring, simple structure, relatively traditional smoke exhaust window is with low costs, the reliability is high, not fragile.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

The embodiment of the utility model provides an including window frame 1, roller bearing 2, spring 3, casement 4, fuse-link 5, rubber heat insulating mattress, hinge 6 and cable wire 7.

The bottom of the window sash 4 is rotatably arranged at the bottom of the window frame 1 through a hinge 6, the window sash 4 can rotate outwards, and the window frame 1 can be opened and closed through the rotation of the window sash 4 to form an outward-opening downward-suspension structure. The hinge 6 ensures the stable connection of the lower parts of the window frame 1 and the window sash 4.

The fuse link 5 is fixed on the top of the window sash 4 and the top of the window frame 1 through bolts, and the window sash 4 and the window frame 1 are fixed together through the fuse link 5; fuse link 5 may be triggered to blow at 73 deg.. The rubber heat insulation pads are fixedly arranged between the fuse link 5 and the window frame 1 and between the fuse link 5 and the window sash 4, the fuse link 5 and the window frame 1, the fuse link 5 and the window sash 4 are isolated by the rubber heat insulation pads, and the conditions that the fuse link 7 is aged and mistakenly broken due to outdoor temperature such as solar radiation heat and the like of the window frame 1 and the window sash 4 are avoided.

The spring 3 is fixed between the window sash 4 and the window frame 1, one end of the spring is connected with the window frame 1, and the other end of the spring is connected with the window sash 4; the spring 3 is arranged in compression. After the fuse link 5 is fused, the spring 3 provides an initial force to push the window sash 4 outward.

The roller 2 is horizontally arranged and rotatably mounted on the top of the window frame 1. The steel cable 7 is wound on the roller 2 and is fixedly connected with the top of the window sash 4.

When the smoke temperature triggers the fuse link 5 to be fused after a fire disaster happens, the spring 3 provides initial thrust to push the window sash 4 outwards, the window sash 4 rotates outwards, and the window frame 1 is opened to discharge smoke. The steel cable 7 is wound on the roller 2 at ordinary times, and after the window sash 4 is pushed open, the steel cable 7 is released until the window sash 4 is completely released, so that the window sash 4 is pulled and fixed; the length of the steel cable can be adjusted according to the angle of the smoke exhaust window.

In addition, it should be noted that the specific embodiments described in the present specification may be different in the components, the shapes of the components, the names of the components, and the like, and the above description is only an example of the structure of the present invention. All the equivalent changes or simple changes made according to the structure, characteristics and principle of the utility model are included in the protection scope of the utility model. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
