Flexible rod-shaped chain link type door window opener

Abstract

The invention discloses a flexible rod-shaped chain link type door window opener, and belongs to the technical field of mechanical engineering. The invention adopts the technical proposal that: the door window opener comprises a connecting base (1), a connecting rod (2), a flexible main rod piece (3), a stander (5), a transmission mechanism (7) and a motor (8), wherein the connecting base (1) canbe fixed on a window body or a door; one end of the connecting rod (2) is connected with the connecting base (1), and the other end of the connecting rod (2) is connected with the main rod piece (3);the transmission mechanism (7) is fixed on the stander (5); the main rod piece (3) is matched with the transmission mechanism (7); and the motor (8) is connected with the transmission mechanism (7). The door window opener has the characteristic of flexible folding of the chain structure, saves a working space, overcomes the flexible characteristic of the chain structure, can lock the door and thewindow when the door and the window are closed, has a simple structure, is safe and convenient to use, replaces manual opening for the door and the window through a mechanical mode, can be widely applied to various buildings, and realizes automatic opening or closing of the door and the window; and the window or the door after opening is not easy to sway.

Description

technical field [0001] The invention relates to a novel door and window opener, in particular to a bendable rod-shaped chain link type door and window opener, which belongs to the technical field of mechanical engineering. Background technique [0002] The door and window opener is a kind of device specially used for opening and closing doors and windows. It replaces the manual opening of doors and windows by mechanical means, and is widely used in modern buildings, especially the chain window opener, because of its simple structure and small space. characteristics are very popular. However, due to the flexibility of the chain structure in the existing chain-type window openers, the window is easy to shake after opening the window, and the opening of the window is unstable. The window opener with a rod structure is stable in opening the window, and the window does not shake, but because the rod cannot be bent and folded, the working space is larger. Moreover, the existing ...

Problems solved by technology

However, due to the flexibility of the chain structure of the existing chain-type window openers, the window is easy to shake after opening the window, and the window opening is unstable.

The rod-type window opener is stable in opening the window, and the window does not shake, but because the rod cannot be bent and folded, the working space is larger

Moreover, the existing window drive adopts gear transmission or screw transmission, and the noise is relatively large during operation.
