Utility model content

Main purpose of the present utility model is to provide a kind of casement window limiting lock, makes casement window cannot be fully opened to avoid children's accident of falling down from the building that meets accident, and has auxiliary anti-theft feature simultaneously; And easy installation and removal, does not need professional, without boring, do not affect the structure of window and attractive in appearance.

For achieving the above object, the technical solution of the utility model is as follows: a kind of casement window is assembled in the casement window limiting lock between window frame and the handle of window while opening an angle, it is characterized in that, main body, described main body, comprises panel, front panel, front C shape lid, positioner, base plate, rear C shape lid, squab panel, has a screw rod of locating by positioner in described main body, described screw axial is vertical with described front and back wallboard; Shank of the key, the circular hole that passes described body front wall plate is connected with described screw rod one end; Position-limited rack, its one end is connected with C shape lid after main body by riveting parts, its other end limited location slotted eye, window handle can be inserted in described spacing slotted eye; Movable clip block, one side is connected with described screw rod by connector but is unfixing, makes straight line come and go mobile with the rotation of described shank of the key; Block, is fixedly connected with rear C shape lid with described main body base plate.

For locating the positioner of described screw rod, by internal thread, match with described external thread of screw, described screw rod rotatablely moves and drives described movable clip block to do the round movement of straight line.

One end of described screw rod, there is a hole at middle part, coordinate with described shank of the key, the other end, there is a flange to be connected with described movable clip block by connector, shank of the key enters in described screw hole through the circular hole of described body front wall plate, rotates shank of the key and drives screw rod to rotatablely move, thereby drive described movable clip block to make straight line, comes and goes mobile.

According to the needs of spacing left and right windows, rivet by riveting parts and position-limited rack on rear C shape lid left side or the right side of described main body.

In the spacing slotted eye of described position-limited rack, there is rubber ring.

The double wall of described movable clip block has rubber pad, and this rubber pad is in the face of described block.

A kind of casement window of the present utility model is assembled in the casement window limiting lock between window frame and window handle while opening an angle, can enter by the stopper slot borehole jack of position-limited rack the handle of window, and by the clamping of movable clip block and block, casement window is gripped, make the handle of window be subject to the position-limiting action of position-limited rack and can only open a low-angle, thereby window cannot be fully opened, to avoid the child accident accident of falling down from the building to occur, and there is auxiliary anti-theft feature.In addition, the utility model not only installing/dismounting is easy, and does not need professional and professional tool while installing, and without boring, does not affect the structure of window and attractive in appearance.
