Detailed Description

The utility model will be further described in detail with reference to examples of embodiments shown in the drawings.

As shown with reference to figures 1-5,

the anti-abrasion door and window hinge comprises a fixed plate 1 and a driving rod 2 hinged with the fixed plate 1, wherein one end, close to a window sash, of the driving rod 2 is hinged with a window sash linkage rod 3, a sliding rod 4 is linked between the window sash linkage rod 3 and the fixed plate 1, the middle part of the sliding rod 4 is hinged with the driving rod 2, the fixed plate 1 is provided with a sliding groove 11, a hinge piece 5 is arranged between the sliding rod 4 and the sliding groove 11, the upper end of the hinge piece 5 is hinged with the sliding rod 4, the lower end of the hinge piece is hinged with a sliding block 6, and the sliding block 6 moves reciprocally in the sliding groove 11; the hinge joint of the driving rod 2 and the fixed plate 1 is provided with a rubber gasket 7 for spacing the driving rod 2 and the fixed plate 1.

Referring to fig. 1, in this embodiment, a fixing plate 1 is used to be mounted in cooperation with a frame, a door and window is mounted on a sliding rod 4 through a window sash linkage rod 3, and the door and window is pushed to open and close in a hinged cooperation manner, during the opening process of the door and window, the driving rod 2 is pulled first to move, and due to the hinged effect, the sliding rod 4 is also slid along, and meanwhile, a sliding block 6 on the sliding rod 4 slides in a sliding groove 11, and at this time, the sliding direction of the sliding block 6 slides towards one end far away from the driving rod 2. When the door and window is closed, firstly the door and window is pressed to the driving rod 2, the sliding rod 4 can also be carried to slide due to the hinging effect, and the sliding block 6 slides towards the direction of the driving rod 2 until the door and window is closed.

In this course of working, in order to let the activity of initiative pole 2 and slide bar 4 more nimble, all keep certain clearance between initiative pole 2 and slide bar 4 and the fixed plate 1, also have certain error space, be convenient for install when the door and window assembly.

In this scheme, the position at initiative pole 2 and fixed plate 1 articulated has newly increased rubber packing ring 7, can keep apart initiative pole 2 and fixed plate 1 relatively, makes the gap between initiative pole 2 and the fixed plate 1 of articulated department, can also possess elasticity buffering space simultaneously, also can provide certain error range when the installation, in addition, can also let both reduce friction, reduce wearing and tearing, also reduce the piece because wearing and tearing produce.

In order to make the assembly state of the rubber gasket 7 more stable, the driving rod 2 is hinged with the fixed plate 1 through a bolt 8, and the rubber gasket 7 is coaxially arranged with the bolt 8 and is positioned between the driving rod 2 and the fixed plate 1.

The coaxial connection between the rubber gasket 7 and the bolt 8 can avoid the rubber gasket 7 from falling off in the opening and closing process of the door and window, and is more stable in use.

Furthermore, one end of the bolt 8 is rotatably connected to the driving lever 2, and the other end has an eccentrically arranged connection block 81, which connection block 81 is rotatably connected to the fixing plate 1.

Under this setting, bolt 8 can change the junction position of initiative pole 2 relative to the mounting through rotating, has the fine setting effect relatively, and this fine setting effect can let the door and window hinge of this scheme produce bigger error adaptability. For convenient fine adjustment, the end of the bolt 8 corresponding to the driving rod 2 is provided with an inner hexagonal hole. The hexagonal hole can enable the hexagonal wrench to rotate, fine adjustment is convenient, and the hexagonal hole can be set in a knurled nut mode.

Further, the connection block 81 is rotatably mounted on the fixing plate 1 by caulking. The riveting mode has larger connection strength, and the door and window have certain weight, so that the service life can be longer under the condition that the hinge has larger strength.

The driving rod 2 and the sliding rod 4 are connected in a relatively rotatable manner after being riveted through pins; the sliding rod 4 is provided with a groove 9 corresponding to one end of the fixed plate 1, the position of the groove 9 corresponds to a pin, the pin is positioned in the groove 9, and the end of the pin does not exceed the surface where the opening of the groove 9 is positioned.

In order to further reduce friction, the fixing plate 1 is provided with the groove 9, so that the end part of the pin can be accommodated in the groove 9, and the end part of the pin is prevented from being exposed to generate friction with the fixing plate 1, so that abrasion and chip falling are avoided. Further reducing friction problems.

According to the scheme after the total combination, friction generated among all parts can be reduced, the service life can be prolonged, metal fragments falling from friction are reduced, and the use feeling and evaluation of a user are improved.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
