Description

Self-lock window hook

The utility model belongs to a kind of timber window Self-lock windhook device.

China's building and farm dwelling adopt wooden door and window mostly at present, and what especially rustic home adopted is timber window entirely.Fixedly the window catch kind used of timber window is single, and the life-span is short, and poor reliability because of being shaken for a long time, easily makes window catch come off, and causes the loss of glass and window frame, particularly window forget link up with all the more so.And the window catch that adopts on the steel sash also exists operation inconvenience, problems such as cost height.At present, the good solution of Shang Weiyou.

The utility model main purpose just be to provide install and use on a kind of suitable steel-wood window can self-locking novel window catch.

The utility model is mainly by spacing lock, and seat board is led arm, slide bar, and from locking plate, seated, spring seven parts are formed.Leading arm is strip, one end is connected with seat board, seat board is fixed on the window frame, and the other end is the directed seat of the degree of lip-rounding, cross through hole in the middle, slide bar one end links to each other with seated, the other end passes the through hole of leading arm one end, in the end spacer pin is housed, and is being H shape near having a plurality of vertical sulculuses on the slide bar of spacer pin from locking plate, be installed in the directed block hole of the degree of lip-rounding of leading arm top, both ends of the spring is pressed on the inwall of locking plate and directed seat.During installation seated is installed on the window, again seat board is fixed on the window frame, when windowing, drive in the through hole of slide bar on leading arm with the hand propelled timber window and to slide, during to certain enable possition, the self-locking sheet falls in the sulculus on the slide bar, slide bar can not be moved, thereby play the purpose of fixed casement window.Owing to have a plurality of sulculuses on the slide bar, thereby can regulate the opening degree of window arbitrarily.

The utility model is compared with existing window catch to have simple in structurely, compact, and characteristics such as it is few to take up space, cheap, easy to operate, safe and reliable, practical are a kind of novel window Self-lock windhook devices.
