Problems solved by technology

[0002] When a building fire comes, people in the building often first consider how to escape, while ignoring or having no time to perform smoke exhaust self-rescue, and, in large buildings, the number of windows is often huge, and the escapers need to open them one by one. It is also unrealistic. Like this, the smoke in the building cannot be released in time, which will exacerbate the danger when the fire alarm comes.

Embodiment 1

[0011] Refer to attached figure 1 . The present invention comprises a housing 1, a casement window or door switch chain 2 powered by a motor, a chain positioning plate 3 supporting the chain is provided in the housing, a chain inlet and outlet 4 is provided on the housing, and a The push plate mechanism of the chain is also provided with a connecting seat 5 connected with the window or door, and a connecting plate 6 which is rotatably connected with the connecting seat and connected with the chain. Reference numeral 17 is a sprocket wheel. Reference numeral 18 is the rotation axis of the connecting plate 6 .

[0012] The connection seat 5 is also provided with a connection plate rotation limiter 7 .

[0013] The push plate mechanism is located in the housing, including a push plate 8 and an extension spring 9 thereof, and the push plate is rotatably connected with its mounting seat in front of the matching connection point of the push plate and the extension spring. Refere...

Embodiment 2

[0017] Refer to attached figure 2 . The push plate mechanism of this embodiment is arranged outside the casing, and the push plate mechanism includes a push plate 14 , a guide mechanism thereof, and a compression spring 15 . Push plate is pressed on the chain 2. The guiding of push pedal is realized by the guide connecting rod 16 between the housing 13 of push pedal mechanism, push pedal and stage clip. The guide connecting rod 16 passes through the outlet of the housing 13 to define its moving direction, and further defines the moving direction of the push plate 14, and the others are the same as in the first embodiment.

Abstract

A smoke discharging device of cant type in fire alarm consists of shell body, switching chain driven by motor to open flat door or flat window, positioning plate to support the chain, inlet and outlet of the chain, push pedal mechanism, connection sea for connecting with door or window, connection plate connected to connection seat and the chain. It can open flat window at the first time to discharge smoke when fire alarm is occurred.

Description

technical field [0001] The invention relates to a fire alarm and smoke exhaust device, in particular to a fire alarm and smoke exhaust device for windows and doors. Background technique [0002] When a building fire comes, people in the building often first consider how to escape, while ignoring or having no time to perform smoke exhaust self-rescue, and, in large buildings, the number of windows is often huge, and the escapers need to open them one by one. Also unrealistic, like this, the smog in the building can not be dispersed in time and the dangerous situation when the fire alarm comes more aggravated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fire alarm oblique push type smoke exhaust device that can provide equipment conditions for automatic smoke exhaust when a fire alarm comes. For this reason, the present invention adopts the following technical solutions: it includes a housing, a casement win...
