Types Of Window Security Locks

Plug-in

A lock similar to the principle of a bolt is installed at the bottom of the window sash, and at the same time, several holes are punched at corresponding positions on the outer window sash to limit the opening position of the window. Through the use of the lock cylinder, the functions of anti-theft and anti-child opening are realized.

Squeeze

This kind of window lock originated in Japan, and some domestic manufacturers have introduced it for reference. This kind of window lock is generally free of installation. When used, it is placed on the window rail, and the internal components are driven by the rotation of the key to realize the opening of the two top blocks at the bottom. The outer sash cannot move while blocking the maximum moving distance of the inner sash.

Folded

Folding-type child safety window locks are generally plastic parts, which are glued to a certain position on the glass with double-sided adhesive, and the maximum opening distance of the window is limited by turning up the two flaps, thereby realizing the function of preventing children from falling from the building.

Segmented hook lock

This is a new type of window lock based on the traditional window lock (single-point lock, commonly known as crescent lock). Its most important innovations are the segmented shackle and child protection safety device. The lock hook of the traditional single-point lock has only one hook, which is used to cooperate with the lock body to close the window. On this basis, the new segmented lock hook extends the lock hook to more than ten centimeters, so that the window can be locked when the window opening gap is 6cm and 12cm (or other safe width values). The window opening gap of 6cm is suitable for ventilation when sleeping or turning on the air conditioner, and it is difficult for thieves to open the window lock from the outside to steal from the room. The window gap of 12cm is close to the maximum safety gap (12.7cm) recommended by the World Child Safety Association. In order to prevent children from accidentally opening the window lock, and to facilitate smooth escape in emergency situations, the window lock incorporates a very interesting safety device-keyless anti-misuse opening device. The two points of this safety device are: ① no key is needed, adults can easily open it with the help of flat objects, such as coins, cards, or even fingernails; Difficulties - use flat objects and understand the special opening method; ③It is very simple to put on the safety, just press the knob down. At the same time, this kind of window lock is suitable for most plastic steel and aluminum alloy sliding windows. It is easy to install and does not change the original structure of the window and does not affect the use of the screen window.
