Abstract

The utility model relates to a hinge mechanism for a door of a refrigerator, which is a concealed mechanism to connect the door of the refrigerator with a refrigerator body. The end face of the refrigerator body and the door of the refrigerator is provided with a hinge plate and a hinge box, the hinge plate is connected with the refrigerator body by screws, a rotation shaft which is arranged on the hinge plate is inserted in the rotation hole of the door of the refrigerator, a positioning post which is positioned on the refrigerator body is inserted into the positioning hole of the hinge plate, and a claw which is arranged on the hinge box is matched and clamped tightly with the hook groove of the positioning body. The utility model has the advantages of compact structure and regular appearance, an arc groove which is arranged on the hinge plate and the hinge box limits the opening degree of the door of the refrigerator, and the door of the refrigerator is not connected with the refrigerator body.

Description

The refrigerator doors linkage

The utility model relates to a kind of improvement that connects refrigerator doors and refrigeratory body linkage, is a kind of refrigerator doors linkage specifically.

The hinge of existing connection refrigerator doors and refrigeratory body, its aperture are by the effect of door holder retaining, and door holder shelves shelves have been lived door and can not have been continued out greatly, in case after door holder had kept off bad, door can continue to hold backward, even can collide with casing, the aperture of side door is out of hand.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, a kind of architecture advances is proposed the refrigerator doors linkage, live linkage by door panel shelves, profile is hidden, attractive in appearance, the aperture of door is stuck in the circular groove of linkage by the door panel, prevents owing to the excessive refrigerator body of wounding of door body aperture.

The utility model purpose is realized by following technical scheme:

This refrigerator doors linkage, primary structure includes hinge box, flap, the end face that is primarily characterized in that refrigerator body and refrigerator doors is installed flap, the position of hinge box is shape and chain carrier bar, the corresponding low groove of hinge box, by screw flap is connected on the refrigerator body, a turning cylinder is arranged on the flap, insert in the rotation hole of refrigerator doors, a reference column is arranged on the refrigerator body, insert in the locating hole of flap, there is the hook groove of opposite position on hook and the refrigerator body to match below the hinge box, the hinge box fastening is at the end face of refrigerator body and refrigerator doors, and covers flap.

In the end of refrigerator doors, there is a panel in the outside, concave part of assembling hinge and hinge box, retaining is in the outside of hinge box, flap.Just cannot see hinge box, flap from the refrigerator front, more attractive in appearance, hidden.Refrigerator doors is opened, and strengthens aperture gradually, and when reaching 140 ° of limiting values, the afterbody of door panel is stuck in the circular groove fully, and refrigerator doors can not continue to open.Can prevent the excessive and refrigerator body of wounding of an aperture like this.Hinge box is plastic products, and upper surface is smooth, an arc groove is arranged on one jiao, and soffit has many laterally and vertical reinforcing ribs, to improve the intensity of hinge box.Periphery has 6 hooks.Flap is a sheet-metal work, has 3 to be used to be connected the hole on the refrigerator body, 1 locating hole and 1 turning cylinder above, and a hook groove is arranged on one of them limit, matches with a hook on the hinge box, connects hinge box and flap; With the corresponding position of hinge box circular groove a circular groove that shape is identical is arranged; There is the stiffened edge of gaining in strength that upwards bends up on the one jiao of adjacent both sides that is contained in the refrigerator doors upper end.In refrigerator body is installed the low groove of flap 3 screw holes that are used for connecting flap are arranged, 5 hook grooves are arranged on the limit of low groove, position, the shape of hook are corresponding on its position, shape and the flap.

The utility model advantage is rational in infrastructure, attractive in appearance, can't see linkage inside from the refrigerator outside, and appearance is very neat.When opening refrigerator doors, the door panel changes in the circular groove of hinge box, can not bump with refrigerator body, even the backstop of opening the door at refrigerator doors middle part is because of fortuitous event when ineffective, the maximum opening that this circular groove can limit refrigerator doors is 140 °, prevents that refrigerator doors from hitting on refrigerator body.
