Abstract

The utility model discloses an invisible hinge for window belongs to door and window hinge field, including the bottom plate that is fixed in the window frame, be fixed in the mounting panel of casement and the coupling assembling of connecting bottom plate and mounting panel, still include: the bottom plate is provided with a sliding groove, the sliding block is connected with the sliding groove in a sliding mode, and the connecting assembly is movably connected with the sliding block; the locating part, the locating part sets up on the spout, when the slider slided to with the locating part butt, the mounting panel formed 60 degrees angles or 90 degrees angles with the bottom plate. Under the angle restriction of locating part, if there is other buildings outside the window and hinders the normal open and shut of window, under the restriction of locating part, the window can only be opened to the angle of restriction, has avoided the condition emergence that casement and building bump, plays the effect of protection to the window.

Description

Invisible hinge for window

Technical Field

The utility model relates to a door and window hinge technical field especially relates to a stealthy hinge is used to window.

Background

The window of present day can realize opening and closing of window through hidden hinge, the window frame and the casement of the hand swinging-out casement window of prior art generally are through hinge or ordinary friction hinged joint, the angle that the casement opened and shut except opening to the maximum limit angle, do not have all the other limiting mechanism, its angle that opens and shuts needs operating personnel to predict, if there are other buildings outside the window, lack under the condition of opening and shutting angle limiting mechanism, when operating personnel opened the casement, the casement extremely easily collides with the building, has the safety problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a window is with stealthy hinge not enough to prior art exists, the utility model aims to provide a window has the advantage that the angle of opening and shutting can be restricted.

In order to achieve the above purpose, the utility model can be realized by the following technical proposal:

the utility model provides an invisible hinge for window, is including the bottom plate that is fixed in the window frame, be fixed in the mounting panel of casement and the coupling assembling of connecting bottom plate and mounting panel, still includes:

the bottom plate is provided with a sliding groove, the sliding block is connected with the sliding groove in a sliding mode, and the connecting assembly is movably connected with the sliding block;

the locating part, the locating part sets up on the spout, when the slider slided to with the locating part butt, the mounting panel formed 60 degrees angles or 90 degrees angles with the bottom plate.

Preferably, the connection assembly includes:

one end of the first connecting rod is rotatably connected with the end part of the mounting plate, and the other end of the first connecting rod is rotatably connected with the sliding block;

one end of the second connecting rod is rotatably connected with the middle part of the mounting plate;

one end of the bearing connecting rod is rotatably connected with the bottom plate, and the other end of the bearing connecting rod is rotatably connected with the end part of the second connecting rod; the first connecting rod is rotatably connected with the bearing connecting rod.

Preferably, the limiting member is detachably connected with the sliding groove.

Preferably, the limiting member is connected with the sliding groove in a snap-fit manner.

The utility model has the advantages that: the window is limited by the limiting piece, if other buildings are arranged outside the window to prevent the window from being opened and closed normally, the window can be opened to the limited angle only under the limitation of the limiting piece, the condition that the window sash collides with the building is avoided, and the window is protected.

fig. 2 is a specific structural diagram of a position-limiting element according to an embodiment of the present invention.

Reference numerals: 1. a base plate; 2. mounting a plate; 3. a slider; 4. a limiting member; 5. a chute; 6. a first link; 7. a second link; 8. a load bearing link.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

referring to fig. 1 and 2, the invisible hinge for a window includes a base plate 1 fixed to a window frame, an installation plate 2 fixed to a window sash, and a connection assembly connecting the base plate 1 and the installation plate 2. The hinge also comprises a sliding block 3 and a limiting piece 4, a sliding groove 5 is formed in the bottom plate 1, the sliding block 3 is in sliding connection with the sliding groove 5, and the connecting assembly is movably connected with the sliding block 3; the limiting member 4 is disposed on the sliding groove 5, when the sliding block 3 slides to abut against the limiting member 4, the mounting plate 2 and the bottom plate 1 form an angle of 60 degrees or 90 degrees, the formed angle is related to the length of the limiting member 4, if the length of the limiting member 4 is longer, the sliding path of the sliding block 3 is shorter, the opening and closing angle of the window sash is small, and in this embodiment, the mounting plate 2 and the bottom plate 1 form an angle of 90 degrees.

The angle of the limiting piece 4 is limited, if other buildings are arranged outside the window to prevent the window from being normally opened, the window can only be opened to the limited angle under the limitation of the limiting piece 4, the angle is 90 degrees, the condition that the window sash collides with the building is avoided, and the window is protected.

The connecting assembly comprises a first connecting rod 6, a second connecting rod 7 and a bearing connecting rod 8. One end of the first connecting rod 6 is rotatably connected with the end part of the mounting plate 2, and the other end of the first connecting rod is rotatably connected with the sliding block 3; one end of the second connecting rod 7 is rotatably connected with the middle part of the mounting plate 2; one end of the bearing connecting rod 8 is rotatably connected with the bottom plate 1, the other end of the bearing connecting rod is rotatably connected with the end part of the second connecting rod 7, and the first connecting rod 6 is rotatably connected with the bearing connecting rod 8.

Preferably, the limiting member 4 is detachably connected to the sliding groove 5, and in this embodiment, the limiting member 4 is connected to the sliding groove 5 in a snap-fit manner, so that the limiting member 4 can be conveniently mounted and dismounted, and when the problem that the normal opening and closing of the window is hindered is solved, the limiting member 4 is pulled out by an operator, so that the limitation of the opening and closing angle of the window sash can be removed.

Various other equivalent changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should fall within the protective scope of the present invention.
