the flange 12 extends downward from the bottom of the cam member 9, when the cam member 9 is vertical, the flange 12 is positioned at the rear side of the roller 5, and when the top of the hinge head 6 rotates to the rear side, the flange 12 rotates from the rear side of the roller 5 to the top of the roller 5 and then reaches the front side of the roller 5.
The cam element 9 is fixed between the two side plates of the hinge head 6 by the upper hinge head shaft 7 and the lower hinge head shaft 8.
The hinge head 6 is hinged with a hinge seat 11 through a hinge head upper shaft 7, and the hinge head upper shaft 7 penetrates through a shaft hole in the top of the hinge seat 11.
The bottom of the shaft hole is provided with a long hole 4 extending along the length of the hinge seat 11, and the roller 5 is arranged in the long hole 4.
The roller frame 10 is connected with the roller 5 through a roller 5 hole at the top of the roller frame.
A spring 1 is arranged along the length direction of the spring rod 2, and the spring 1 is coiled on the spring rod 2.
When the cam member 9 is vertical, the spring 1 is in a compressed state.
The hinge structure comprises a door body and a box body, wherein the front side of a hinge head 6 is fixed on the rear side of the door body, and the front side of a hinge seat 11 is fixed on the rear side of the box body.
The working method of the horizontal refrigerator comprises the following steps: when the door is opened, a user lifts the door body, the front end of the door body moves upwards, the top of the rear side of the door body also rotates upwards and backwards to drive the hinge head 6 to rotate together, the top of the hinge head 6 rotates backwards, the bottom of the hinge head rotates forwards to drive the cam part 9 fixed on the hinge head 6 to rotate, the flange 12 moves forwards to cross the top of the roller 5, the spring 1 releases the compression state at the moment, and the door body cannot be automatically closed;
when the door is closed, a user closes the door body, the front end of the door body moves downwards at the moment, the top of the rear side of the door body also rotates downwards and forwards to drive the hinge head 6 to rotate together, the top of the hinge head 6 rotates forwards at the moment, the bottom of the hinge head rotates backwards to drive the cam part 9 fixed on the hinge head 6 to rotate, the flange 12 moves backwards, the roller 5 can be extruded downwards by the flange 12 at the moment, the spring 1 is extruded into a compression state from a non-compression state, meanwhile, the flange 12 can cross the top of the roller 5, namely a balance point of a cam structure, and reaches the rear side of the roller 5, the door body is completely closed at the moment, and the roller 5 can be extruded upwards due to the fact that the spring 1 is in the compression state, the roller 5 abuts against the flange 12, and the door body is closed tightly.
In a specific arrangement, the flange 12 should be inclined to the rear side to ensure that the flange 12 is positioned at the rear side of the roller 5 when the cam member 9 is vertical, but the surface of the top of the flange 12 extending to the front side of the cam member 9 should be a curved surface to make the flange 12 move forward, and when the roller 5 is pressed, the surfaces of the flange 12 which rub against each other are curved surfaces to prevent the equipment from being damaged. The magnitude of the spring force when the door is closed can be determined by the material selection of the spring 1. When the flange 12 moves forwards and passes over the top of the roller 5, the compression state of the spring 1 is released continuously forwards, if a hinge with damping capacity is matched, the hovering capacity of the door body can be realized, but when the door body is to be closed, the elastic force of the spring 1 can tightly close the door body.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
