Wrenching and buckling type window opening limiter

Abstract

The invention provides a wrenching and buckling type window opening limiter which is arranged at the inner side of a transverse window frame of an external window sash of transverse pull type aluminum door and window. When the limiter is outwards wrenched by a clamping and stopping block which is movably accommodated in an accommodating room of a seat body, a buckling piece close to the clamping and stopping block is buckled at a clamping and buckling part of the clamping and stopping block in a sliding way, so that the clamping and stopping block is in a convex and locking stop status, thereby limiting the openable distance between an outer window sash and an inner window sash; and when the stopping and limiting functions need to be relieved, the buckling piece close to the clamping and stopping block is movably separated from the clamping and buckling part, and the clamping and stopping block can be wrenched to be retracted into the accommodating room of the seat body, so that the window sashes can be completely opened.

Description

technical field [0001] The present invention relates to the design of a window opening limiter, which can be used to stop and control the openable width of the inner and outer window sashes when the pull-type locking block set by the limiter is pulled out. It is especially suitable for Horizontal pull aluminum doors and windows for security. Background technique [0002] In the design of the current building, in order to allow light and fresh air to enter the room from the outside, aluminum doors and windows are made on the walls of the building. However, in order to prevent thieves from invading after breaking the glass through aluminum doors and windows, and to make the sash more secure after opening, it is often necessary to install an iron window or aluminum grille outside the window for protection. Unauthorized opening of windows and falling accidents, but it also hinders the effect of real-time escape in the event of a fire. Iron windows or aluminum grilles will block...

[0003] However, when the catch block of this limiter is raised, it also forms a lock function. Although it can be used as a safety window to prevent children from climbing, it also has the effect of preservation, and when an emergency occurs, the catch can be released. The block is retracted into the chamber so that the window sash can be fully opened for use, but since the locking block is controlled by a lock unit, every time it is used, whether it is to make the locking block rise or retract, It is necessary to drive the lock unit with a key, which is quite inconvenient to use, and in order to prevent children from easily opening the lock unit, parents often store the key, but they cannot find it when an emergency occurs. keys, so there are also security concerns
