Description

Technical Field

[0001] This utility model relates to the field of sliding doors and windows, and in particular to a latch assembly for sliding doors and windows and a sliding door and window. Background Technology

[0002] Sliding doors and windows are very common in daily life. As an essential decorative door and window in modern home decoration, they greatly improve the utilization of indoor space compared to ordinary rotating doors and windows because their opening mechanism is sliding. Currently, sliding doors and windows on the market include two types: those that cannot be fully opened and those that can be fully opened. Fully openable sliding doors and windows refer to those that can be partially opened by sliding, as well as fully opened by rotating. When creating a sliding door and window that can be both pushed and fully opened by rotating, the sliding track consists of two parts: a fixed track fixed to the upper part of the door and window frame, and a movable track fixed to the top of the fixed door and window frame. The sliding door and window must slide from the fixed track to the movable track to overlap with the fixed door and window and then rotate.

[0003] When a sliding door or window has more than one sliding door, the sliding doors may move simultaneously during the sliding process. This makes it impossible to fix one of the sliding doors in certain special situations and usage environments. Therefore, there is an urgent need to provide a latch assembly for sliding doors and windows, as well as a sliding door or window itself, to solve the above problems. Summary of the Invention

The mounting base 101 is provided with a rotating groove 102, and one end of the eccentric block 201 is rotatably disposed in the rotating groove 102. A first opening 103 adapted to the extension of the eccentric block 201 is opened on the mounting base 101 below the first opening 103. The trigger rod 302 is in contact with the eccentric block 201 below the first opening 103 of the mounting base 101. In the implementation of this embodiment, the mounting base 101 is disposed on a movable door leaf 5 or a fully open fixed door leaf 6 that needs to be fixed. Under the action of the weight of the eccentric block 201, the tail end of the eccentric block 201 can extend out of the first opening 103 and fall into the socket 402 in the ground, or a socket 401 with a socket 402 is provided on the ground at the corresponding position to lock the tail end of the eccentric block 201. The trigger rod 302 is mounted on the push-pull movable door leaf 5. When the trigger rod 302 approaches the mounting base 101, the trigger rod 302 abuts against the eccentric block 201 below the mounting base 101.
