Description

Technical Field

[0001] The utility model relates to the technical field of sliding windows, in particular to a sliding window with a passive lock. Background Technique

[0002] Sliding windows are divided into horizontal sliding windows and vertical sliding windows according to different sliding directions. Horizontal sliding windows need to be provided with rail grooves above and below the window sash, and vertical sliding windows require pulleys and balancing measures; sliding windows have the advantages of not occupying indoor space, beautiful appearance, economical price, and good sealing performance. With high-grade slide rails, it can be easily pushed open with a gentle push. With large pieces of glass, it not only increases indoor lighting but also improves the overall appearance of the building;

[0003] Existing sliding windows already have handle locks. Unlocking the sliding window is achieved by turning the handle lock to open it. However, in families with children, the handle locks of conventional windows are very easy to be opened by children. The easily opened sliding windows can easily pose a danger to children. Therefore, a sliding window with a passive lock is invented. Content of the Utility Model

[0007] In a preferred embodiment of the utility model, the passive lock is composed of an upper shell, a lower shell, a lock block, and a handle.

[0008] In a preferred embodiment of the utility model, the upper shell is provided with a first pin at both ends, and the lower shell is provided with a second pin at both ends. The first pin is cooperatively connected with the second pin.

[0009] In a preferred embodiment of the utility model, a handle is installed inside the upper shell and the lower shell. A lock tongue is provided at the right end of the handle. A cavity is opened inside the lower shell. The lock tongue is arranged at the position of the cavity.

[0010] In a preferred embodiment of the utility model, a spring positioning pin is fixedly provided on the inner wall of the cavity. A spring is provided on the spring positioning pin. One end of the spring away from the spring positioning pin is connected to the lock tongue. The lock tongue corresponds to the position of the lock hole block. An arc-shaped groove is opened on the handle.

[0011] In a preferred embodiment of the present utility model, a round hole is provided on the upper housing. The lock block includes a lock pin, a positioning ring, and a convex pin. The lock pin extends into the inner wall of the round hole. A positioning ring is fixedly installed below the outer wall of the lock pin. The top of the positioning ring fits against the bottom of the upper housing. A convex pin is fixedly provided at the bottom of the positioning ring, and the convex pin is connected to the arc-shaped groove of the handle.

[0012] Additional aspects and advantages of the present utility model will be given in part in the following description, become apparent in part from the following description, or be understood through the practice of the present utility model.

[0013] Passive locks are fixedly installed below both ends of the inner side of the metal window frame. A lock hole block is fixedly installed on the sliding window, and the passive lock is connected to the lock hole block. When the sliding window is closed, the lock hole block moves to the position of the lock tongue, and the lock tongue enters the inside of the lock hole block under the action of a spring, thereby achieving the use effect of the passive lock and preventing children from accidentally opening the sliding window.

[0014] When it is necessary to close the passive lock, insert an external wrench into the lock pin and rotate the lock pin. The convex pin of the positioning ring rotates inside the arc-shaped groove, causing the handle to move backward, so that the lock tongue is retracted into the lower housing. The operation is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS
