Anti-misoperation device and door and window assembly

Abstract

The invention provides an anti-misoperation device and a door and window assembly. The anti-misoperation device can be used for being installed on the door and window assembly and comprises a self-lock device and a magnetic attraction base. The self-lock device comprises an installing base, a lock pin and an elastic piece. The lock pin is movably arranged on the installing base. One side of the elastic piece is connected with the installing base in a jacking manner, and the other side of the elastic piece is connected with the lock pin in a jacking manner so that the lock pin can be positioned. When the lock pin gets away from the magnetic attraction base, the lock pin is pushed by elastic force of the elastic piece, part of the lock pin penetrates out of the installing base. When the lockpin gets close to the magnetic attraction base, the lock pin overcomes the elastic force of the elastic piece under the action of attraction force of the magnetic attraction base and moves in the direction of the magnetic attraction base, and the lock pin contracts into the installing base. In the anti-misoperation device and the door and window assembly, when the lock pin is matched with a transmission rod on the door and window assembly, movement of the transmission rod can be limited, accordingly, a lock point connected with the transmission rod is prevented from moving, accordingly, the situation that when a user touches a handle by accident, through the transmission rod, the handle pushes out the lock point into the state that the lock point is engaged with the lock base is avoided,and the situation that when the user closes sector sectional materials, the lock base and the lock point are in mutual collision is avoided.

Description

technical field [0001] The invention relates to the field of hardware, in particular to an anti-misoperation device and a door and window assembly. Background technique [0002] A door and window assembly generally includes a frame profile and a fan profile, and the fan profile is movably installed on the frame profile. In the prior art, the fan profile and the frame profile are generally locked through the cooperation of the lock point and the lock seat. The lock seat is installed on the frame profile, and the lock point is installed on the fan profile and connected with the transmission device. The user controls the transmission by holding the hand. The device is used to push the lock point to engage or separate from the lock seat through the transmission device, but when the fan profile is in the open state, the user is likely to accidentally touch the handle and push the lock point to the state when it is engaged with the lock seat, and the lock point is in this state. ...
