Abstract

The utility model relates to a hinge used on a refrigerator door, which comprises a hinge seat, a hinge shaft sleeve and an elastic top bar device, wherein the hinge seat comprises a connecting body formed by a rotary shaft, a rotary arm and a chassis, and the elastic top bar device comprises a combined body formed by a top bar, a seat body and a spring. The refrigerator door hinge is characterized in that the hinge seat, the hinge shaft sleeve and the elastic top bar device are all independent pieces, and each independent piece is used under the states of combing and mounting, the hinge shaft sleeve is arranged in a hinge shaft sleeve hole of a refrigerator door, the rotary shaft is mounted in the hinge shaft sleeve, the chassis is connected with the box body of a refrigerator, the lower portion of an eccentric circular arc end of the rotary arm is provided with the elastic top bar device which is fixed on the refrigerator door, and a thimble of the elastic top bar device supports the rotary arm. The refrigerator door hinge has the advantages that a refrigerator can not have the phenomena that the door of the refrigerator can not be tightly closed, or has flash seams during long term use, can not cause the outward flow of cold energy, and saves power consumption.

Description

The refrigerator doors hinge

Technical field

The utility model relates to a kind of hinge, relates in particular to a kind of hinge that is used on the refrigerator doors.

Background technology

Existing refrigerator doors hinge arrangement does not mostly have automatic closing device, and the refrigerator doors closure is that the suction by sealing strip is implemented, and refrigerator is prone to refrigerator doors and is not closed completely or the seam of sudden strain of a muscle phenomenon is arranged in long-term use, cause cold to leak, and increases power consumption.

Summary of the invention

The technical problems to be solved in the utility model is: at the problem that above-mentioned refrigerator doors in use exists, design the hinge that a kind of meeting makes the refrigerator doors auto-closing.

The technical solution of the utility model is: the refrigerator doors hinge, it is located between refrigerator body and the chamber door, comprise hinge seat, hinge shaft sleeve, the elastic push rod device, described hinge seat comprises rotating shaft, pivoted arm, the connector that base constitutes, described elastic push rod device comprises push rod, pedestal, the assembly that spring constitutes, it is characterized in that: described hinge seat, hinge shaft sleeve, the elastic push rod device is a separate piece, each separate piece is used under the combination installment state, hinge shaft sleeve is arranged in the hinge axis trepanning of chamber door, rotating shaft is installed in the hinge shaft sleeve, base connects refrigerator body, an elastic push rod device that is fixed on the chamber door is set below the eccentric arc end of pivoted arm, and the thimble of elastic push rod device withstands pivoted arm.

Described hinge seat is one and at one end is provided with the rotating shaft that connects single chamber door or upper and lower door, the contact radius R of rotating shaft of chamber door closed condition and thimble for one side or tow sides on the pivoted arm of eccentric arc end ₁The contact radius R of rotating shaft of＜chamber door opening and thimble ₂, be provided with the die casting of the base that connects refrigerator body at the other end.

Described push rod is the cylinder that an interlude is provided with stage.

The beneficial effects of the utility model are: when chamber door is closed the door angle during less than 90 °, hinge seat will rotate under the push rod thrust, chamber door is closed automatically, refrigerator refrigerator doors just can not occur and be not closed completely or the seam of sudden strain of a muscle phenomenon is arranged in long-term use, can not cause cold to leak, save power consumption.
