Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1 to 3, in an embodiment of the present utility model, a hinge cover with an induction device for a refrigerator includes an upper hinge 1, an upper mounting plate 3, an upper rotating shaft 2, a lower hinge 4, a lower mounting plate 7, a connecting plate 5, and an induction alarm mechanism.

The rear end face fixedly connected with of going up hinge 1 goes up mounting panel 3, goes up mounting panel 3 and refrigerator upper inner wall and passes through bolt fixed connection, go up hinge 1's upper surface outer edge fixedly connected with and go up pivot 2, go up pivot 2 and refrigerator chamber door upper end rotation connection, the rear end face fixedly connected with of lower hinge 4 goes down mounting panel 7, and lower mounting panel 7 passes through bolt fixed connection with the refrigerator lower surface, lower hinge 4's upper surface outer end rotation is connected with connecting plate 5, connecting plate 5 and refrigerator chamber door lower surface fixed connection.

The refrigerator is connected to the door body by the upper hinge 1 and the lower hinge 4 so that the two can rotate relatively.
