Abstract

The invention relates to a door-and-window locking and positioning device which comprises a door-and-window wind brace and a transmission device. The door-and-window wind brace comprises a strip-shaped main frame, a supporting rod, a positioning assembly and a lifting assembly. The positioning assembly comprises a slide block and a rack. One end of the supporting rod is hinged to the slide block which is connected to a slide groove of the main frame in a sliding mode. The rack is arranged below the slide block. A tooth-shaped portion which corresponds to the rack is arranged on the lower surface of the slide block. The lifting assembly, which is used for controlling the rack and the tooth-shaped portion of the slide block to be meshed or separated, is arranged in the main frame and is fixedly connected with the rack. According to the door-and-window locking and positioning device, the lifting assembly is used for controlling the tooth-shaped portion of the slide block to be meshed with or separated from the rack at any position, so that the slide block can be fixedly positioned at any position of the rack, accordingly, a door and window can be opened by any angle to be fixed, use convenience of the door-and-window locking and positioning device is improved, and meanwhile the door and window can be positioned more reliably and firmly due to meshing of the tooth-shaped portion and the rack.

Description

technical field [0001] The invention relates to structural accessories for doors and windows, in particular to a locking and positioning device for doors and windows. Background technique [0002] Most window structures are generally equipped with wind braces as window positioning devices, so that the window blades can resist certain external forces (such as wind force, etc.) and maintain a certain angle after opening to ensure ventilation and light transmission. Door Structure With the advancement of technology and the growth of people's needs, many door structures using wind braces have also appeared, which are also used to keep the door at a certain angle to ensure certain ventilation and light transmission. [0003] Traditional wind braces generally can only be opened at a fixed angle and kept at that angle, or can be kept fixed at three or four given angles. The opening stages and opening angles of such wind braces have been fixed, and the opening degree of doors and w...
