The movable valve body 10 comprises a sliding block 11, a pressing wheel 12 and a spring piece 13, the sliding block 11 is provided with a groove, the pressing wheel 12 is arranged in the groove, the pressing wheel 12 is connected with the side walls at two ends of the groove through a shaft 2, the pressing wheel 12 is connected with the sliding block 11, the pressing wheel 12 can rotate in the sliding block 11, and one end of the pressing wheel 12 protrudes out of the upper surface of the sliding block 11.

The slider 11 is arranged at the bottom end of the rotating shaft 30, and the pinch roller 12 is in surface contact with the rotating shaft 30.

The lower surface of the sliding block 11 is provided with the spring piece 13, and the other end of the spring piece 13 is connected with the movable valve body 10 through a screw.

One end of the spring piece 13 is abutted against the sliding block 11 to push the pressing wheel 12 to press the rotating shaft 30, when the pressing wheel 12 just enters the arc-shaped groove 31, the edge of the arc-shaped groove 31 is contacted and pressed, and the tangential force pushes the rotating shaft 30 to rotate. The rotating shaft rotates 30 until the pressing wheel 12 rolls to the bottom of the arc-shaped groove 31, the pressure of the pressing wheel 12 on the arc-shaped groove 31 and the reaction force applied to the pressing wheel are located on the same straight line, and the relative positions of the pressing wheel 12 and the arc-shaped groove 31 are in a stable state. At this time, the hinge is in a normally closed state, and the relative position of the movable valve body 10 and the fixed valve body 20 is 180 degrees.

When external force promotes door and window the movable valve body 10 drives on the hinge the interactive subassembly of movable valve body 10 rotates, axis of rotation 30 is also rotated, pinch roller 12 receives radial force and is greater than it and passes through the slider 11 lower extreme receives the pressure of spring leaf 13 to it is former to be released arc recess 31 then the 30 surfaces of axis of rotation roll, roll into until roll into another on 30 surfaces of axis of rotation arc recess 31 bottom. The pressure of the pressing wheel 12 on the arc-shaped groove 31 and the reaction force applied to the pressing wheel are positioned on the same straight line, and the relative position of the pressing wheel 12 and the arc-shaped groove 31 is in a stable state. At this time, the hinge is in a normally open state, and the relative position of the movable valve body 10 and the fixed valve body 20 is 90 °.

When the hinge is installed, the position of the movable valve body 10 relative to the fixed valve body 20 may be more or less than 180 ° when the hinge is in the closed state due to a reference surface problem or an installation problem in the field.

At this time, the flat end fastening screw 1 on the movable valve body 10 can be loosened, the rotating shaft 30 is loosened, the movable valve body 10 is rotated by an external force, and after the position of the flat end fastening screw 1 is 180 degrees opposite to the fixed valve body 20, the flat end fastening screw 1 is locked again, so that the rotating shaft 30 and the movable valve body 10 are fixed into a whole again. At this time, the door closing angle when the door leaf is closed is 180 °, and the movable valve body 10 and the fixed valve body 20 are in the same plane.

The fixed valve body 20 comprises a buffer 21 and a swing hook 22, one end of the buffer 21 is connected with the fixed valve body 20 through a rivet, the other end of the buffer 21 is provided with a movable rod 211, the movable rod 211 is connected with the lower end of the swing hook 22 through a rivet, the other end of the swing hook 22 is connected with the fixed valve body 20 through a rivet, and at the moment, the swing hook 22 is equivalent to a special-shaped lever.

The surface of the movable valve body 10 facing the fixed valve body 20 is provided with a projection 111.

The surface of the swing hook 22 facing the movable valve body 10 is provided with a linkage groove 221, and the projection 111 of the movable valve body 10 can be embedded into the linkage groove 221 of the swing hook 22.

In the process of opening the hinge, the protrusion 111 of the movable valve body 10 and the swing hook 22 are relatively displaced, so that the swing hook 22 rotates around a lever fulcrum formed by the rivet and the rivet, one end of the swing hook 22 pushes the movable rod 211 to retract into the buffer 21, at the moment, the one-way valve of the buffer 21 is opened, the air/liquid in the cylinder is discharged, and the movable rod 211 has no resistance. The protrusion 111 of the movable valve body 10 is separated from the linkage groove 221 of the swing hook 22, and then the movable rod 211 is continuously opened, so that the state of the buffer 21 is stable and unchanged.

When the hinge is closed, the projection 111 of the movable valve body 10 is separated from the interlocking groove 221 of the swing hook 22 to be in contact with the interlocking groove. When the two parts are separated, the door and the window are closed without resistance.

When the protrusion 111 of the movable valve body 10 starts to be inserted into the linkage groove 221 of the swing hook 22, the swing hook 22 is driven to rotate, and the movable rod 211 of the buffer 21 is pulled. At this moment buffer 21's check valve is closed, forms the vacuum in the cavity, the movable rod 211 passes through pendulum hook 22 is right movable valve body 10 the resistance is applyed to lug 111 part, slows down closing speed, and the angle of closing the door when closing up to door and window is 180, movable valve body 10 with fixed valve body 20 is in same plane, and door and window accomplishes and closes.

The design structure of the lever arm of force of the swing hook 22 can enlarge the force of the micro air pressure/hydraulic buffer, so that the micro air pressure/hydraulic buffer can have larger damping to delay the closing action of larger doors and windows.

When the protrusion 111 of the movable valve body 10 starts to be inserted into the interlocking groove 221 of the swing hook 22, the damper 21 starts to output resistance. Through different design schemes of the stress point and the curved surface of the swing hook 22, the specific position of the protrusion 111 of the movable valve body 10, which is embedded into the linkage groove 221 of the swing hook 22, can be set, so that the angle at which the hinge is closed when the buffer 21 starts to output resistance is set.

To sum up, the utility model discloses a hinge with buffer adopts for safety closing door and window and prevent to damage the hinge buffer 21 and pendulum hook 22 forms and takes lever structure as the buffering subassembly, when closing door and window, when the angle of hinge reachs an appointed angle, the buffering subassembly begins to act on, reduces closing speed.
