Detailed Description
The utility model is further illustrated by the following figures and examples, which are not intended to be limiting.
As shown in fig. 1-5, a rear and adjustable intermediate locking device is provided in the connection area between the inner leaf profile 7 and the outer frame profile 8; the inner fan chute 2 of the inner fan section bar 7 is provided with a frame part locking block 4 in a sliding way, and the outer frame chute 1 of the outer frame section bar 8 is provided with a fan part locking block 5 in a sliding way; the frame part locking block 4 and the fan part locking block 5 are internally and respectively provided with a connecting hole 9 in a penetrating way, and are provided with a locking piece 3 matched with the connecting holes 9, one end part of the locking piece 3 extends out of the connecting holes 9 to be clamped with the inner fan sliding groove 2 or the outer frame sliding groove 1, so that the fan part locking block 5 is clamped and installed in the inner fan sliding groove 2 through the locking piece 3, and the frame part locking block 4 is clamped and installed in the outer frame sliding groove 1 through the locking piece 3; the frame part locking blocks 4 and the fan part locking blocks 5 are mutually in abutting fit through the arc-shaped surfaces 6.
The middle locking device is limited in the middle area of the inner fan chute 2 and the outer frame chute 1.
In this embodiment, when fixedly installed with the inner fan, the fan locking block 5 is placed in the inner fan chute 2, and is fixed at the inner fan chute 2 by means of the locking piece 3, so that the fan locking block 5 does not need to be pre-penetrated before the window fan is assembled, and the problem that once the window fan is assembled, the window fan cannot be installed without penetrating in advance is avoided. Likewise, the frame part locking piece 4 is arranged in the outer frame sliding groove 1, after the position of the window sash locking piece 4 is determined, the upper and lower heights of the frame part locking piece 4 are adjusted, the fan part locking piece 5 and the cambered surface of the frame part locking piece 4 are guaranteed to be effectively attached, and the problem that the window frame cannot be installed once the corner is assembled without penetrating into the window frame in advance can be avoided by means of the locking piece 3 being fixed at the outer frame sliding groove 1.
As shown in fig. 5, specifically, the end surface of the connecting side of the frame part locking block 4 and the fan part locking block 5 is provided with a first arc surface part, and the first arc surface part is in a convex arc surface shape on the section; the end face of the side, connected with the frame part locking block 4, of the fan part locking block 5 is provided with a second arc surface part which is in a concave arc surface shape on the section; the first cambered surface part and the second cambered surface part are mutually attached and matched so as to facilitate the opening and closing of the window sashes.
It should be noted that, because the frame portion locking block 4 and the fan portion locking block 5 adopt the matched design of the arc-shaped surface 6 instead of the simple inclined straight surface design, the window sash can be smoother when being rotationally closed through the arc-shaped surface, and the instant clamping phenomenon when the top of the locking block is contacted can not occur.
Wherein, the connecting holes 9 in the frame part locking block 4 and the fan part locking block 5 are staggered with the arc-shaped surface 6. Avoiding affecting the matching condition of the cambered surfaces on the frame part locking block 4 and the fan part locking block 5.
