Casement window hardware device with limiting and security-protection functions, and window body

Abstract

The invention discloses a casement window locking device with limiting and security-protection functions, and a window body. The casement window locking device comprises a handle base and a handle which are fixed on the side edge of an sash, wherein a shifting fork is controlled by the handle; a limiting guide rod is driven to vertically slide by the shifting fork; a vertical sliding groove in the limiting guide rod is in sliding fit with the tail end of a limiting pulling rod on a limiting device; the limiting device has a locking position; the sash can be controlled to be opened and positioned by the rotation angle of the handle. According to the device and the window body, the locking strength is high, a good positioning function is provided, the whole sash can be opened completely, the danger caused by the factor that a user separates the limiting pulling rod from the vertical sliding groove can be prevented, the structure is simple, the installation is easy, and the requirements of an existing building on the use functions of the doors and windows are extremely met, and expanding and implementing are benefited.

Description

technical field [0001] The invention belongs to the technical field of locking and positioning of casement windows, and in particular relates to a hardware device and a window body of a casement window with positioning and security functions. Background technique [0002] At present, most of the existing casement windows do not have a convenient and reliable positioning function, nor can they effectively limit the opening angle, which easily leads to dangerous behaviors of users jumping out of the window. Although some casement windows adopt the structure of positioning through tie rods, in fact, this type of tie rods cannot be locked, and only rely on wind braces to form friction to restrict the degree of freedom of the window sash. In this case, if the external force is large There is still the possibility of wiggling or self-closing. After a long time of use, due to the wear of the sliding contact surface, it is easy to generate noise and difficult to locate. There are ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a casement window hardware device with limiting and security functions to solve the common problems of casement windows in the prior art, such as inability to lock the position and insufficient positioning strength due to unreasonable structural design. And the window, the casement window can be opened or locked by rotating the handle (handle) angle and cooperating with a certain pulling force or pushing force. The open state can be positioned by the limit pull rod, or the limit pull rod can be temporarily abandoned to make the entire window sash fully open.
