The utility model discloses the technical scheme who adopts as follows:

the utility model provides a hidden door and window hinge, including first hinge piece, second hinge piece and hinge axle, the hinge axle is the articulated shaft of first hinge piece and second hinge piece, first hinge piece is including the hinge page and the hinge cantilever that are the L type, the second hinge piece is also including the hinge page and the hinge cantilever that are the L type, the hinge face of first hinge piece passes through screwed connection to the casement section bar, the hinge face of second hinge piece passes through screwed connection to the sash frame section bar, the hinge axle extends through the hinge cantilever and is located the casement and is close to outdoor side, hug closely casement panel inboard.

As a further improvement of the above technical solution:

the second hinge sheet is consistent with the first hinge sheet and has the same bending direction.

The length of the hinge cantilever of the second hinge plate is less than that of the hinge cantilever of the first hinge plate.

The second hinge leaf is provided with a notch for accommodating the hinge cantilever of the first hinge leaf.

The first hinge sheet and the second hinge sheet can be folded together.

Enough space is left at the frame, which accommodates the hinge shaft, inside the sash panel for the hinge shaft to rotate.

The opening angle of the window sash panel is more than 90 degrees.

The utility model has the advantages as follows:

the utility model discloses a hinge piece of two L types rotates around the hinge axle, can fold and can stretch out, utilizes the position change in the space, realizes opening and closing of casement. The utility model discloses a hinge axle extends through the hinge cantilever and is located the casement and is close outdoor side, hug closely casement panel inboard, leaves sufficient space in the window frame department that casement axle was held to casement panel inboard and makes the hinge axle rotate, realizes the opening angle more than 90. The utility model discloses a hidden structure, when realizing that the casement opens and close the function, the hinge is hidden inside the building curtain, does not destroy the whole visual effect of the outer facade of building, can protect the hinge moreover, increases the life of hinge, reduces its adverse effect that receives external environment. The utility model discloses on the basis of original casement and fan frame section bar, realize hidden structure's improvement, satisfy the sealed effect of casement. The utility model discloses can be applicable to the curtain panel casement of multiple form, also can be applicable to the casement structure of heavy weight, large tracts of land.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 3, the hidden hinge for doors and windows comprises a first hinge plate 1, a second hinge plate 2 and a hinge shaft 3, wherein one end of the first hinge plate 1 is hinged to one end of the second hinge plate 2, and the hinge shaft 3 is a hinged shaft of the first hinge plate 1 and the second hinge plate 2. The first hinge piece 1 comprises an L-shaped hinge surface 4 and a hinge cantilever 5, the second hinge piece 2 also comprises an L-shaped hinge surface 4 and a hinge cantilever 5, and the second hinge piece 2 is consistent with the first hinge piece 1 and has the same bending direction. The length of the hinge cantilever 5 of the second hinge plate 2 is less than that of the hinge cantilever 5 of the first hinge plate 1. The second hinge plate 2 is provided with a gap for accommodating the hinge cantilever 5 of the first hinge plate 1, so that the first hinge plate 1 and the second hinge plate 2 can be folded together. As shown in fig. 4 to 5, the hinge surface 4 of the first hinge leaf 1 is connected to the sash profile 6 by screws, the hinge surface 4 of the second hinge leaf 2 is connected to the sash frame profile 7 by screws, the hinge shaft 3 extends through the hinge cantilever 5 to be located close to the outdoor side of the sash and closely attached to the inner side of the sash panel 8, and enough space is left at the window frame which accommodates the hinge shaft 3 at the inner side of the sash panel 8 to enable the hinge shaft 3 to rotate. The hidden door and window hinge adopts 316 stainless steel, and ensures long-term use effect.

The utility model discloses when implementing, with first hinge leaf 1 through the screw connection to casement section bar 6 on, second hinge leaf 2 through the screw connection to fan frame section bar 7 on, hinge axle 3 extends through hinge cantilever 5 and is located the casement and is close outdoor side, hug closely casement panel 8 inboardly. After the installation is accomplished, the utility model discloses a hidden door and window hinge is used for connecting casement section bar 6 and fan frame section bar 7, makes the casement rotate for fan frame and opens or close. When the window is used, a fireman pulls open the window sash through the handle from the outdoor side, the window sash is opened to 90 degrees or slightly more than 90 degrees through the hidden door and window hinge, and the fireman smoothly enters the room for rescue. Since the first hinge plate 1 and the second hinge plate 2 are hinged by the hinge shaft 3, the window sash can be opened to 90 degrees. Because the hinge shaft 3 is hidden at the inner side of the window sash panel 8, after the window sash is opened and closed, the hidden door and window hinge can realize the hiding function and does not damage the overall appearance effect of the outer vertical surface of a building.

The utility model discloses can be applicable to the curtain panel casement of multiple form, for example stone material curtain wall rescue window, ceramic plate curtain wall rescue window, glass curtain wall rescue window, aluminum plate curtain wall rescue window and so on, also can be applicable to the casement structure of heavy weight, large tracts of land.

The above description is illustrative of the present invention and is not intended to limit the present invention, and the present invention may be modified in any manner without departing from the spirit of the present invention.
