Embodiment Construction

[0021] Examples, see Figure 1 to Figure 4 Shown: the window opening machine can be opened manually, including the casing 10. The casing 10 is provided with a slide rail 11 . A slider 20 is slidably disposed on the slide rail 11 , and a handle 21 is connected to the slider 20 . That is, by manipulating the handle 21 , the slider 20 can be moved along the slide rail 11 . A worm gear motor 30 is fixed on the slider 20 . That is, the worm gear motor 30 moves along with the slider 20 . The worm gear motor 30 generally includes a motor, a worm is fixed on a power output shaft of the motor, and the worm is equipped with a worm gear, and the worm gear realizes power output. At the same time, the housing 10 is also fixed with a reduction gear set 40 for connecting the window opening parts of the window opening machine, and the worm gear motor 30 is matched with the reduction gear set 40 . The so-called matching here refers to that the worm gear of the worm gear motor 30 can mesh ...

Abstract

The invention discloses a window opener capable of achieving manual opening. The window opener comprises a machine shell. A slide rail is arranged on the machine shell. A slide block is arranged on the slide rail in a sliding mode and is connected with a handle. A worm and gear motor is fixed to the slide block. Meanwhile, a speed reduction gear set used for being connected with a window opening part of the window opener is fixed to the machine shell. The worm and gear motor is matched with the speed reduction gear set. The window opener has the advantage that it can be ensured that a smoke discharge window can still be smoothly opened in the electricity-free state.

Description

technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to a window opening machine that can be opened manually. Background technique [0002] With the improvement of people's fire safety awareness and standard requirements, the use of building smoke exhaust window openers is increasing. However, the existing window openers for building smoke exhaust windows are slow in opening speed and time-consuming to open, and the chain window opener is difficult to open without electricity, which not only fails to meet the requirements of fire protection regulations, but also brings certain risks to building fire safety. Hidden danger. Therefore, it is particularly necessary to develop a chain type window opener that can be manually opened under abnormal conditions such as no electricity or no fire signals. Contents of the invention [0003] The purpose of the present invention is to provide a window opening machine that can be...
