Novel manual window opener

Abstract

The novel manual window opening machine of the present invention is provided with driving wheel, transmission shaft with gear, tooth rack, guide rail slide plate, base, casing, connecting rod. The hand turns the handle of the driving handwheel, the driving handwheel drives the transmission shaft to rotate, the transmission shaft is connected to the gear to make the gear rotate, the gear and the rack mesh to make the rotation change to move, the rack makes the rolling guide slide move along the rolling guide base, and the connecting rod Connected in the guide groove of the slide, the connecting rod moves horizontally with the slide. When the sash is pushed and pulled, the connecting rod is connected with the fixed block, and the fixed block is fixedly connected with the vertical frame of the opened sash, and the sash is pulled open with the horizontal movement of the connecting rod; when the sash is oppositely opened, the connecting rod moves in the guide groove of the guide plate Thereby the connecting plate is promoted, and the opposite fan window fixedly connected with the connecting plate is opened. The advantages are that the manufacturing process is simple, the cost is low, the operation is convenient, and the window can be opened quickly, and the escape probability is improved when a fire occurs.

Description

technical field [0001] The invention relates to a window opening machine, in particular, it is a manual device for manipulating the opening of double-layer windows. Background technique [0002] When a fire breaks out in a high-rise building, doors and windows become an important escape route for people.

The existing single-layer sash opening method is to directly pull the latch, and the person directly pushes and pulls the sash handle, so that the sash is unscrewed around the window frame on one side. But in the northern region, because the weather is relatively cold, people generally use double-layer windows to achieve the effect of heat preservation and noise reduction. Difficult and seriously affects escape time. There is a mechanical automatic window opener, which can quickly open the window, but it is only suitable for the opening of a single window sash, and it must be connected to the powe...
