Problems solved by technology

But there is following problem in this hinge device of prior art: the elastic force of spring is to pass to side cover 5 by slide cam and rotating cam 8 on the shaft 7, when rotating cam 8 contacts with side cover 5, the elastic force of spring is stressed The area is relatively small, so if figure 1 Cracks are prone to appear on the side cover 5 as shown and eventually lead to damage
In order to solve this problem, it is necessary to use a higher strength material to make the side cover 5, but this will increase the production cost

Embodiment Construction

[0024] figure 2 It is a three-dimensional view of the rear structure of a top-opening door type refrigerator provided with the hinge device provided by the present invention. image 3 An exploded perspective view of the partial structure of the hinge device provided by the present invention. Figure 4 A sectional view of important parts of the hinge device provided by the present invention. Such as Figure 2 ~ Figure 4 As shown, a storage space not shown in the figure is formed inside the refrigerator body 10 . The storage space forms an opening on the upper part of the refrigerator body 10 and can be opened and closed through a door 12 . The door 12 is arranged on the body 10 of the refrigerator, and is opened and closed by a hinge device 20 to be described below. That is, the refrigerator door 12 realizes the function of opening and closing by being connected to the hinge device 20 at the upper end of the back of the refrigerator body 10 and the rear end of the door 12 ...

Abstract

The present invention discloses a top door-opened type refrigerator hinge joint device. It includes the following several portions: external shell, side cover, shaft, rotary cam and slide cam. It is characterized by that on the described rotary cam, in the position where the rotary cam is tightly connected with the inside surface of said side cover several dispersive projections are formed, so that these dispersive projections can make the contacted area of said rotary cam with said side cover be relatively increased, and the elastic force of the spring can be dispersed, then transferred to the side cover, therefore the durability of said side cover can be raised.

Description

technical field [0001] The invention relates to a hinged device for a top-opening door type refrigerator, in particular to a hinged device for a top-opening door type refrigerator capable of increasing the strength of a side cover. Background technique [0002] Refrigerators can maintain the temperature of the interior space according to the pre-setting to achieve the purpose of keeping the items in the interior fresh for a long time, so the refrigerators have various styles. The present invention is described based on the content of the hinge device arranged at the door shaft of the top-opening type refrigerator. The door of the top-loading refrigerator is always facing the direction opposite to its gravity when it is opened, so in order to prevent the impact caused by its gravity when opening and closing the door, use such as figure 1 Articulation shown. figure 1 It is an exploded perspective view of the structure of the refrigerator hinge device in the prior art. Such ...
