Door and window capable of controlling and adjusting angle and convenient to open, close and lock

Abstract

The invention discloses a door and window capable of controlling and adjusting an angle and convenient to open, close and lock, and belongs to the technical field of doors and windows. The door and window comprises a door and window frame, movable connecting frames are arranged on the inner side of the door and window frame, gauze is arranged on the outer walls of the movable connecting frames, and a pulling plate is arranged on the outer wall of the left end of the leftmost group of movable connecting frames; a bearing seat is arranged at the joint of a movable connecting frame and the gauze, a volute spiral spring is arranged at the joint of the movable connecting frame and the bearing seat, a limiting protruding block is arranged at the bottom of an inner cavity of the door and window frame, and sliding blocks are arranged on the outer walls of the left side and the right side of the bottom of the pulling plate. According to the door and window capable of controlling and adjusting the angle and convenient to open, close and lock, at present, the movable connecting frame and the gauze are arranged on the bearing seat in the mode that the movable connecting frame and the gauze are connected through a movable shaft and the volute spiral spring, so that the gauze can be adjusted and controlled at more angles, the pulling plate driving the gauze to move is clamped and fixed in the inner wall of the door and window frame, and the door and window frame can be integrally closed and fixed conveniently through a linked mechanical mechanism; and the whole is more attractive and convenient to use.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a door and window with controllable angle adjustment and easy opening, closing and locking. Background technique [0002] During the use of doors and windows in the prior art, folding gauzes are generally installed in the doors and windows. In the prior art, the folded gauzes are fixed at a bending angle, so that the gauzes cannot be fully opened and closed, which is not convenient. Adjust the size of the gauze in the doors and windows. After the gauze is opened and closed, the angle is fixed and cannot be adjusted conveniently. Then, the pull plate in the door and window frame that drives the gauze to move cannot be quickly fixed on the inner wall of the door and window frame when it is in use. When fixing, the traditional lock method is used to affect the external appearance, and the operation is also convenient, but also the same damage. For this reason, we propose ...
