In the figure: 1 first fixed plate, 2 second fixed plate, 3 fixed handle, 4 action bars, 5 arc wall, 6 locking plate, 7 through groove, 8 connecting rod, 9 handles, 10 mounting groove, 11 locking rod, 12 recess, 13 springs.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
According to the latch mechanism for doors and windows shown in fig. 1-3, the latch mechanism for doors and windows comprises a first fixed plate 1 and a second fixed plate 2, wherein a fixed handle 3 is rotatably arranged on the first fixed plate 1, an operating rod 4 is rotatably arranged on the second fixed plate 2, one side of the operating rod 4 is provided with an arc-shaped groove 5, the fixed handle 3 is movably arranged in the arc-shaped groove 5, a locking plate 6 is arranged on the second fixed plate 2, a locking opening is arranged on the locking plate 6, one end of the operating rod 4 is arranged in the locking opening, the lower surface of one end of the operating rod 4 is provided with an installation groove 10, one side of the installation groove 10 is provided with a through groove 7, the second fixed plate 2 on one side of the locking plate 6 is provided with a groove 12, a spring 13 is arranged in the groove 12, the top of the spring 13 is contacted with a locking rod 11, the top of the locking rod 11 is provided with a connecting rod 8, and the locking rod 11 is matched with the installation groove 10.
The lower opening of the arc-shaped groove 5, the fixed handle 3 slides into the arc-shaped groove 5 through the lower opening of the arc-shaped groove 5, and thus the fixed handle 3 can be fixed.
