AI Technical Summary

Technical Problem

The locking system of existing windows or doors has problems such as complex structure, easy to jam, bulky and high cost, making it difficult to achieve the effects of anti-theft and space saving at the same time.

Method used

A simple and compact locking device is designed. Through the combination of the central body, handle and movable rod, the rotational movement of the handle and the translational movement of the projection are used to lock and unlock the movable frame, avoiding the coordination of gears and racks.

Benefits of technology

The reliability and smooth movement of the locking device are achieved, avoiding the problem of jamming, reducing the complexity and cost of the system, and providing effective anti-theft function.

Abstract

The locking device comprises a central body (1) and a handle (2) with moving means (4) engaging with a rod (3). The handle is rotatable between an open position and a closed position. In the closed position, an effective anti-collision device is provided to prevent movement of the rod. Thus, the moving device (4) comprises a rotor (41) and a single projection (42) which engages with a seat (312) of a moving element (31) of the rod (3); rotation of the handle to the closed position results in blocking of the moving element (31) by interaction of the edge of the seat (312a) with the raised head (421). As a result, a locking device for windows or doors (e.g., sliding doors and windows), having anti-theft characteristics, is provided.
