Manual locking device with handle for terrace security screen}

The present invention relates to a manual locking device with a handle for a terrace security screen, and more particularly, as the handle for operating the locking device is configured in a structure exposed to the indoor and outdoor sides at the same time, the locking device can be operated simultaneously indoors and outdoors.

BACKGROUND ART In general, windows of apartment houses or detached houses are almost always equipped with insect repellent windows to prevent pests such as mosquitoes and flies from flying into the room from the outside when the windows are opened.

However, these conventional insect screens always remain closed while the window is open, but there is a problem that there is no separate locking device, so they are always exposed to crime. In addition, there is a problem that the window is frequently opened by children or children, resulting in frequent safety accidents in which children or children fall.

In order to solve such conventional problems, Korean Patent Registration No. 10-1554332 has invented a "safety locking device installed on an insect screen frame", but this safety locking device includes a first body portion installed on the frame; a second body part installed on the window frame, detachable from the first body part to allow the frame to be separated from the window frame, or attached to the first body part to prevent the frame from being separated from the window frame; a rotating part installed in the first body part and rotating so that the second body part is detachable from the first body part; and a moving part movably installed in the first main body part and preventing rotation of the pivoting part by being in contact with the pivoting part.

In the prior art, since the movable unit is provided in a state of being exposed to the indoor side and is configured to enable operation of the locking device, when the locking device is locked while the user is on the terrace, a problem occurs in which the user is trapped on the terrace.

In addition, the prior art has problems in that the operation is inconvenient, and the structure of the locking device is complicated, so that manufacturing is difficult, so that not only a lot of manpower is consumed in manufacturing, but also the manufacturing cost is high.
