Description
Technical Field
The utility model belongs to the technical field of door and window accessories, and particularly relates to a sliding support hinge for connecting a window sash and a window frame.
Background
The conventional window sliding support hinge generally comprises a base, a short cantilever, an inclined cantilever, a long cantilever, a support arm, a positioning rapier head and a positioning piece, wherein one end of the short cantilever, one end of the inclined cantilever and one end of the long cantilever are respectively hinged to the base, the other end of the short cantilever is hinged to the long cantilever, the other ends of the inclined cantilever and the long cantilever are respectively hinged to the support arm, the positioning rapier head is installed at the bottom of the support arm, and the positioning piece is installed at the end part of one end of the base and is connected with the positioning rapier head in a positioning and matching mode when the support arm is folded and folded, namely a window sash is closed. According to the window sliding support hinge with the conventional structure, as the hinged connection of the inclined cantilever and the long cantilever on the support arm is not restricted, when the window sash is opened, namely the support arm is unfolded, the opening angle of the window sash is not restricted, the opening angle of the window sash is easily overlarge, even the support arm is excessively unfolded under the condition of wind power and other inefficient forces, so that the sliding support hinge is damaged, or the privacy or safety problem is caused by the overlarge opening angle of the window sash.
SUMMERY OF THE UTILITY MODEL
In view of the shortcomings of the prior art, the utility model aims to provide a window sliding support hinge with a limited opening angle.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a window sliding support hinge with limited opening angle comprises a base, an inclined cantilever, a long cantilever, a support arm, a positioning sword head and a positioning piece, wherein one ends of the inclined cantilever and the long cantilever are respectively hinged to the base, the other ends of the inclined cantilever and the long cantilever are respectively hinged to the support arm, the positioning sword head is installed at the bottom of the support arm, the positioning piece is installed at the end part of one end of the base and is connected with the positioning sword head in a positioning matching mode when the support arm is folded, a positioning piece is convexly arranged on the positioning sword head and is positioned between the hinged parts of the inclined cantilever and the support arm and between the hinged parts of the long cantilever and the support arm, and the positioning piece can be used for blocking the hinged parts of the inclined cantilever, the long cantilever and the support arm so as to limit the unfolding amplitude of the support arm when a window sash is opened, namely the support arm is unfolded, and plays a role of limiting the opening angle of the window sash.
Preferably, the limiting piece is a fin punched and formed from the positioning sword head.
The utility model has the following beneficial effects:
the window sliding support hinge with limited opening angle is characterized in that limiting pieces are convexly arranged on the positioning sword head between the hinged parts of the inclined cantilever and the support arm and between the hinged parts of the long cantilever and the support arm, and the limiting pieces can block the hinged parts of the inclined cantilever, the long cantilever and the support arm when a window sash is opened, namely the support arm is unfolded, so that the unfolding amplitude of the support arm is limited, and the effect of limiting the opening angle of the window sash is achieved.
Drawings
FIG. 1 is a block diagram of a limited opening window slide hinge of the present invention;
fig. 2 is a schematic view of a limiting member of the window sliding support hinge with limited opening angle according to the present invention.
Detailed Description
The utility model will be further described with reference to the accompanying drawings and specific embodiments so as to more clearly understand the technical idea of the utility model claimed.
The window sliding support hinge with the limited opening angle as shown in fig. 1-2 comprises a base 1, a short cantilever 2, an inclined cantilever 3, a long cantilever 4, a support arm 5, a positioning rapier head 6 and a positioning piece 7, wherein one end of the short cantilever 2, one end of the inclined cantilever 3 and one end of the long cantilever 4 are respectively hinged to the base 1, the other end of the short cantilever 2 is hinged to the long cantilever 4, the other end of the inclined cantilever 3 and the other end of the long cantilever 4 are respectively hinged to the support arm 5, the positioning rapier head 6 is installed at the bottom of the support arm 5, and the positioning piece 7 is installed at one end of the base 1 and is connected with the positioning rapier head 6 in a positioning and matching manner when the support arm 5 is folded and folded, namely, a window sash is closed. Limiting pieces 60 are convexly arranged on the positioning rapier head 6 between the hinging parts of the inclined cantilever 3 and the supporting arm 5 and between the hinging parts of the long cantilever 4 and the supporting arm 5, and the limiting pieces 60 can be isolated among the hinging parts of the inclined cantilever 3, the long cantilever 4 and the supporting arm 5 when the window sash is opened, namely the supporting arm 5 is unfolded, so that the unfolding amplitude of the supporting arm 5 is limited, and the effect of limiting the opening angle of the window sash is achieved; in particular, the stop 60 may be in the form of a protruding fin punched directly from the positioning blade 6. Of course, the stopper 60 may be formed by directly mounting a protruding member on the positioning rapier head 6.
It should be noted that the sliding support hinge applicable to the positioning rapier head 6 provided with the limiting member 60 for blocking the hinged portions of the inclined cantilever 3, the long cantilever 4 and the supporting arm 5 so as to limit the unfolding range of the supporting arm 5 is not limited to the sliding support hinge of the casement window with the specific structure shown in fig. 1, but is also applicable to other sliding support hinges with the same structural forms of the inclined cantilever 3, the long cantilever 4, the supporting arm 5 and the positioning rapier head 6, and not listed herein.
Various other changes and modifications to the above-described embodiments and concepts will become apparent to those skilled in the art from the above description, and all such changes and modifications are intended to be included within the scope of the present invention as defined in the appended claims.
