New-style doors and windows with inner side-opening micro-ventilation transmission locker

Abstract

The invention belongs to the field of building doors and windows and particularly relates to a novel inward vertical hinged micro-ventilation transmission locking device for doors and windows. The novel inward vertical hinged micro-ventilation transmission locking device for the doors and windows comprises a gear box, a positioning seat, a connection rod, a rivet, a gear piece, a compressed spring and a slide block, and is characterized in that a rotary gear is mounted in the middle of the inner part of the gear box; a rotary hole is formed in the middle of the rotary gear; a sliding plate and a fixed plate are arranged between the gear box and the rotary gear; an engaging hole is formed in the middle of the sliding plate; the engaging hole is matched with the rotary gear; the middle part of the fixed plate is fixedly connected with the gear box; a plurality of strip-shaped through holes are formed in the surface of the fixed plate; a locking point is fixed at the tail part of the sliding plate; the locking point is connected with the sliding plate through the fixed plate; and a windproof clamping block, a slide block, a cross-shaped pan head screw, a spring gasket and a resetting baffle are arranged between the locking point and the gear box. The different ventilation states can be realized according to requirements of people, a matched safety device can be used for preventing child high-altitude falling accidents from occurring and the requirements of the era are met.

[0004] At present, in the field of building doors and windows, plastic inner casement windows are widely used for their good water tightness, air tightness, wind pressure resistance, and heat preservation, and the inner casement drive locker is essential to ensure the above good performance Choose, this kind of transmission locker refers to the device that realizes the multi-point locking function of doors and windows by turning the handle. The principle is to connect multiple cylindrical lock points on the window sash through connecting rods. Under the operation of the handle, The transmission gear and the sliding plate on the locker drive a number of lock heads to move at the same time, and the lock heads slide into the lock blocks fixed on the window frame, thereby realizing the multi-point locking effect on doors and windows. Imperfect restrictions, the ordinary inner swing drive can only make the doors and windows open and lock

With the improvement of people's living standards, people's requirements for doors and windows are getting higher and higher. The opening volume of the original internal opening micro-ventilation actuator is too small to meet the basic requirements of people's window ventilation.
