Description

Refrigerator Hinges and Refrigerators

technical field

The utility model relates to a hinge device, in particular to a refrigerator hinge; the utility model further relates to a refrigerator provided with the hinge.

Background technique

Refrigerators can be used to refrigerate or freeze food, which greatly facilitates people's lives. When the refrigerator door is opened, in order to prevent the door from colliding with surrounding objects or causing loss of cooling capacity when the door is opened too large, a door opening stop device is usually installed on the refrigerator, which can make the refrigerator door open when it is opened. Stop after a certain angle to prevent the refrigerator door from opening too much. The refrigerator door stop device is usually set on the refrigerator door hinge. Since the hinge itself is the opening and closing part of the refrigerator door, the refrigerator door stop device is set on the refrigerator hinge. It can facilitate the opening control of the refrigerator door and simplify the stop structure, such as the refrigerator door hinge device disclosed in Chinese patent CN2127989, which includes a lower hinge seat (3) fixed on the box body (1), on which a hinge shaft is fixed (4), a, there is an arc-shaped convex circle (9) on the lower hinge seat (3), and there is a stopper (13) at the end of the convex circle (9); b, on the bottom surface of the box door (2) A door stopper (7) is fixed on the position corresponding to the lower hinge seat (3), on which there is an "L" shaped flange (16), and a flange (16) has a contact surface corresponding to the stopper (13). Matching stop surface (15); c, also be fixed with the locking plate (12) that has " V " shape groove (11) on casing (1), on box door (2) bottom surface and locking The corresponding position of sheet (12) fixes the structure of a locking slider (6) with dead bolt (5).

An existing refrigerator door hinge, the hinge includes an upper hinge plate and a lower hinge plate, the upper hinge plate is arranged on the refrigerator door, the lower hinge plate is arranged on the refrigerator box, the lower hinge plate is provided with a rotating shaft, and the upper hinge plate The upper part is equipped with a rotatable bushing set on the rotating shaft, the upper hinge plate and the lower hinge plate are pivotally connected, the upper hinge plate is provided with a stop surface after the upper hinge plate is opened, and the lower hinge plate extends a protrusion and bends to form an upper hinge The stop block after the plate is opened, the stop block includes the outer surface extending from the lower surface of the lower hinge plate, the inner surface extending from the upper surface of the lower hinge plate, the left end face, the right end face and the upper end face, the stop surface of the lower hinge plate is The left end face of the lower hinge plate tab next to the stop surface of the upper hinge plate. The disadvantage of the refrigerator hinge of this structure is: since the metal plate for processing the refrigerator hinge is relatively thin, the stop area of the stop surface formed by the left end surface of the lower hinge plate is small, and when the door is opened, the refrigerator door stops Unstable, it is easy to cause the refrigerator door to shake, which brings inconvenience to the refrigerator users; further, because the refrigerator door has an angle requirement for the opening stop, that is, the stop angle of the refrigerator door cannot be too large or too small, and the refrigerator door must be realized. The control of the opening angle of the body requires processing and control of the angle of the stop surface. Since the stop surface of the lower hinge plate of the refrigerator hinge is formed by bending the protruding part arranged on the lower hinge plate, the left end surface of the protruding part must form a stop. The retaining surface and angle control require high processing technology and the process is complicated.
