Summary of the invention

The purpose of this utility model provides a kind of manufacturing, installation, easy to use, and safety thumb-latch attractive in appearance.

The technical scheme of Cai Yonging is as follows for achieving the above object:

A kind of thumb-latch, it comprises pin and handle, handle links to each other with pin, pin be positioned at door leaf inner and can pass door leaf, the sash sidewall is fixed in lockhole on doorframe, the window frame, be characterized in: the latch main body is a flat box body, and box body is fixed in the door leaf; The axle of handle penetrates in the box body, the axle of box body inside is gone up design the tooth parallel with axle, the both sides design of the inherent axle of box body has connector, connector one end is designed to the strip tooth plate with the contacted face of axle, tooth plate is meshed with tooth on the axle, and the in addition end of two connectors vertically passes box body and links to each other with vertical pin; Connector is limited in box body.

For increasing the fastness after locking, and be the steadiness of multi-door fan vertical hinged door, be connected with branch to plate on the top of pin, divide fulcrum to be fixed on the door leaf to plate, two summits link to each other with vertical pin and horizontal pin respectively in addition, and vertical pin vertical motion can drive horizontal pin transverse movement.

In such scheme, on door leaf, sash side, fairlead is installed, laterally the termination of pin and vertical pin places in the fairlead.

Adopt latch of the present utility model, it has increased fastness by a plurality of lock points of hand control, and convenient and strength-saving, and its integral body is placed in the door leaf except that handle simultaneously, and appearance looks elegant is succinct.

The utility model is described in further detail below in conjunction with drawings and Examples.
