Detailed Description
The invention is described in more detail below with reference to the accompanying drawings. The utility model provides a hinge under inwardly opened interior window, its includes the frame hinge 2 fixed with window frame 1, with the fixed fan hinge 4 of casement 3, its characterized in that: the frame hinge 2 and the fan hinge 4 are connected through an inversion mechanism, the inversion mechanism comprises a rotating shaft body 5, the rotating shaft body 5 is installed in a limit sleeve 21 on the frame hinge 2 in a back-and-forth swinging mode, the inversion mechanism further comprises a rotating shaft rod 6, the rotating shaft rod 6 is inserted into a rotating shaft sleeve 41 arranged on the fan hinge 4, the rotating shaft body 5 and the rotating shaft rod 6 are connected into a whole through a limit table 7, the limit table 7 is borne on a bearing pad 8 arranged on the upper end face of the limit sleeve 21, a sliding cambered surface 81 is arranged on the upper end face of the bearing pad 8, and when the window sashes are opened in an inverted mode, the limit table 7 slides on the surface of the sliding cambered surface 81.
The structure of the rotating shaft body 5 is in a trapezoid shape with a small upper part and a large lower part, the rotating shaft rod 6 is cylindrical, and the limiting table 7 is disc-shaped. The rotating shaft body 5 is made of steel plates, strength is guaranteed, the rotating and drawing rod 6 and the limiting table 7 are formed by rubber, plastic or other wear-resistant materials in a wrapping and injection molding mode, and the friction requirement during movement can be met.
The bearing pad 8 is made of rubber or other wear-resistant plastic materials, the bottom of the bearing pad 8 is provided with a connecting strip 82 in a downward extending mode, and the connecting strip 82 is inserted into the limiting sleeve 21 to fix the bearing pad 8 on the frame hinge 2.
The connecting strips 82 are arranged at the left side and the right side of the swinging direction of the rotating shaft lever 6. The connecting strip 82 plays a role of fixing the bearing pad 8, and also plays a role of isolating the rotating shaft body 5 and the limiting sleeve 21, so that the side wall of the rotating shaft body 5 and the limiting sleeve 21 are prevented from generating working noise due to friction.
The surface of the rotating shaft rod 6 is provided with an encapsulation sleeve, and after the rotating shaft rod 6 and the rotating shaft sleeve 41 are installed, the encapsulation sleeve 61 is positioned between the rotating shaft rod 6 and the rotating shaft sleeve 41.
The sliding cambered surface 81 is transitionally arranged from the upper end surface of the bearing pad 8 to the front end surface of the bearing pad from high to low.
Working principle: as shown in fig. 1 and 2, when a user needs to open the window sash in an inverted mode, a handle on the window sash is operated, an upper hinge above the window sash is driven to be separated from the window frame through a linkage mechanism, and the diagonal draw bar structure is in butt joint with the window frame. At this time, the weight of the whole window sash is applied to the bearing pad 8 through the limiting table 7, and the window sash drives the lower hinge in the scheme to incline to the indoor direction under the traction action of the diagonal draw bar. So that the window sashes are in an inward-tilting and inward-opening state. During the opening process, the bottom of the rotating shaft body 5 swings in the limit sleeve 21, and the limit table 7 slides on the surface of the bearing pad 8. The bearing pad is made of plastic or rubber, so that the bearing pad can play a good supporting role and a damping role when being relatively displaced with the rotating shaft body, working noise is avoided when friction occurs between the bearing pad and the rotating shaft body due to relative movement, the window sash is more stable and silent when being opened and closed, and the texture of operation is improved.
Further: in order to make the window sash more smooth when being opened in a reverse way, the sliding cambered surface 81 in the scheme is transitionally arranged from the upper end surface of the bearing pad 7 to the front end surface of the bearing pad from high to low. The circle center and the radius of the sliding cambered surface are overlapped with the circle center and the radius of the swinging of the rotating shaft body, so that the limiting table can be uniformly stressed on the bearing pad when the surface of the sliding cambered surface slides, and the inner-falling opening and closing can be smoothly performed.
Further: as shown in fig. 3 and 4, when the window sash needs to be opened horizontally, the handle on the window sash is operated, the upper hinge above the window sash is driven to be in butt joint with the window frame through the linkage mechanism, and the diagonal draw bar structure is separated from the window frame. The window sashes rotate by taking the rotating shaft rods 6 of the upper hinge and the lower hinge as circle centers, so that the window sashes can be horizontally opened. Wherein, can be steady quiet operation in order to make the relative motion between pivot pole 6 and pivot cover 41, be provided with the rubber coating cover on pivot pole 6 surface in this case, the hinge during operation, the rubber coating cover is located between pivot pole 6 and pivot cover 41, has played the isolation effect to pivot axle sleeve and pivot pole. Because the rubber coating sleeve is made of plastic, rubber or other wear-resistant materials, the rubber coating sleeve can fill the gap between the rotating shaft rod 6 and the rotating shaft sleeve, so that the situation that the window sashes shake in the opening and closing process due to the gap between the rotating shaft rod 6 and the rotating shaft sleeve is avoided. Similarly, the rubber coating sleeve is made of plastic or rubber, and does not generate noise when the rubber coating sleeve moves relative to the metal, so that the window sash does not generate noise when being opened and closed.
In summary, the hinge structure in the present case is in realizing the casement and falls the inwardly opened, flat-open, flat-closed function simultaneously, and unique connection structure can also make stable, high-efficient, the silence go on when the casement is opened and closed, has the function such as promote operation impression, promotes product grade, so can extensively use widely.
