Detailed Description

The utility model discloses a specific explanation that advances step will be followed to the utility model, kind side is opened and is cushioned the improvement structure that resets, its characterized in that includes mutual articulated fixed hinge seat 2 and activity hinge seat 3, activity hinge seat 3 in be provided with guide way 32, install leading wheel 5 through guiding axle 33 in the guide way 32, be provided with spring 7 between leading wheel 5 and activity hinge seat 3, spring 7 promotes leading wheel 5 and sets up the spigot surface 6 contact on fixed hinge seat 3 to leading wheel 5 slides on spigot surface 6 when the hinge switching, leading surface 6 on be provided with inside sunken recess 61 that resets, when the hinge was closed, leading wheel 5 slided and is fallen into in the recess 61 that resets.

The fixed hinge seat 2 is provided with a hinge shaft 4 which is inserted into a hinge hole 31 on the movable hinge seat 3 and is hinged with the hinge hole,

the fixed hinge base 2 is fixed on the box 11, and the movable hinge base 3 is fixed on the box 1.

The guide groove 32 is a waist-shaped groove, and the hinge shaft 4 is slidably mounted in the waist-shaped groove 32.

The spring 7 is a torsion spring which is L-shaped, and a positioning ring 71 arranged at the free end of the torsion spring is sleeved on the guide shaft 33.

A spring seat 34 is also arranged in the movable hinge seat 3, and the tail end of the spring 7 is clamped in the spring seat 34.

The guide surface 6 is arc-shaped.

The movable hinge seat 3 is also internally provided with a buffer 8, and the top of a buffer rod 81 of the buffer 8 is contacted with the fixed hinge seat 2 to play a role in buffering when the hinge is closed.

The working principle is that a refrigerator is taken as an example for explanation, the hinge comprises a fixed hinge seat fixed on a refrigerator body and a movable hinge seat fixed on a refrigerator , a hinge shaft is arranged on the fixed hinge seat and is inserted into the hinge seat on the movable hinge seat to be hinged with the hinge seat, in the opening and closing process of the hinge, a spring pushes a guide wheel to move towards the direction of a guide surface all the time, so that the guide wheel is positioned on the surface of the guide surface to slide, when the hinge is closed to fixed angle, the guide wheel slides into a reset groove from the guide surface, in the process that the guide wheel enters the reset groove, the guide wheel and the reset groove interact to generate pushing force of a switch , so that the refrigerator is automatically closed, and after the refrigerator is closed, the guide wheel is clamped in the reset groove to generate pressure of a switch , so that the refrigerator can be tightly closed to avoid leakage.
