Safety limiting device used for push-pull window

Abstract

The invention discloses a safety limiting device used for a push-pull window, wherein the push-pull window comprises a piece of inner glass and a piece of outer glass which are arranged symmetrically left and right, the safety limiting device comprises a support plate and a limiting stop block, wherein one side of the support plate is adhered to the outer side of the piece of inner glass or the inner side of the piece of outer glass in a bonding or sucking disc adsorbing way, and the limiting stop block is arranged on the other side of the support plate; and the thickness of the support plate is smaller than a gap between the piece of the inner glass and the piece of the outer glass, and the thicknesses of the support plate and the limiting stop block are larger than the gap. The safety limiting device provided by the invention has the benefits as followings: control to relative displacement between the piece of the inner glass and the piece of outer glass is achieved through the limiting stop block so as to limit the maximal opened width of the push-pull window, safety can be achieved under the condition of ensuring ventilation, children are prevented from climbing out of the window, burglars are prevented from entering from the window, and normal window opening cannot be influenced when the limiting stop block is demounted. Moreover, the way of bonding or adsorbing to glass ensures nondestructive mounting.

Description

technical field [0001] The invention relates to a safety limit device for a sliding window, in particular to a safety limit device for limiting the opening width of an inner glass or an outer glass. Background technique [0002] Such as Figure 16 As shown, a traditional sliding window 500 includes left and right inner glass 501 and outer glass 502, wherein the inner glass 501 is also called an inner fan, and the outer glass 502 is also called an outer fan. By pushing the inner glass 501 or the outer glass 502 to move horizontally, the window can be opened to a certain width to facilitate ventilation. The inner glass 501 and outer glass 502 of some sliding windows 500 can move horizontally, and one of the inner glass 501 and outer glass 502 of some sliding windows 500 is fixedly set, and the other is set to be horizontally movable, and can be moved horizontally by pushing and pulling. The movable door can be opened to a certain width. In the sliding window 500 of the prior...

Problems solved by technology

[0003] The defect of the prior art is that only the sliding window in the fully closed position can be locked. When the window is opened to a certain width, since the opening width of the window can be changed by pushing and pulling the inner glass 501 or the outer glass 502, there is a great security. Hazards, such as thieves who may enter the house through the window, and accidents caused by children climbing out of the window
