Embodiment Construction

[0015] Examples, see figure 1 Shown: there is no electricity to conveniently open the window opening machine, including casing 10. The casing 10 is provided with a window opening component 20, and the window opening component 20 may be a chain or other components connected to the exhaust window. The window opening component 20 is connected with a reduction gear set 30 disposed on the casing 10 . That is, after the reduction gear set 30 works, the window opening component 20 drives the smoke exhaust window to open or close.

[0016] combine Figure 2 to Figure 5 As shown, a fixed shaft 11 is fixed to the right of the reduction gear set 30 inside the casing 10 . A mounting plate 40 is hinged on the fixed shaft 11 . That is, the mounting plate 40 is rotatable around the fixed shaft 11 as a rotation axis. A screw motor 50 matched with the reduction gear set 30 is fixed on the mounting plate 40 . The so-called lead screw motor means that the power output shaft of the motor is...

Abstract

The invention discloses a window opener convenient to open under a nonelectric state. The window opener comprises a shell, wherein a window opening component is arranged in the shell; the window opening component is connected to a reduction gear unit arranged on the shell; a fixed shaft is fixed, on the right of the reduction gear unit, in the shell; the fixed shaft is hinged to a mounting plate; a screw motor matched with the reduction gear unit is fixed on the mounting plate; the mounting plate is provided with a spring capable of enabling a screw of the screw motor to be far away from the reduction gear unit; meanwhile, the shell is hinged to a handle; a 7-shaped gear slot is formed in the shell; the handle slides in the gear slot; the handle and the screw motor are linked. The window opener has the advantage that a smoke discharge window can be normally opened under the nonelectric state.

Description

technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to a window opener that can be easily opened without electricity. 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 opener that can be...
