Embodiment 1

[0023] Such as figure 1 , figure 2 The shown hinge device includes a hinge body 11, a hinge shaft 12 and a hinge sleeve 13, wherein the hinge body 11 is detachably connected between the box body and the door body 5 by screws or bolts, and the connection relationship can be referred to Figure 4 as indicated in the. The hinge shaft 12 is vertically movably installed on the hinge body 11, and can also be integrally cast with the hinge body. The hinge sleeve 13 is sleeved outside the hinge shaft 12 and positioned above the hinge body 11 to support The door body 5 is also provided with a door closing unit 2 on the hinge device. The door closing unit 2 includes: a pin shaft 21, a through hole 113 is formed on the hinge body 11, and the pin shaft passes through the hinge body 11 to form a the through hole 113, and the top of the pin is formed with a convex portion 2111 with a smooth slope and corresponding to the groove 3a formed at the bottom of the refrigerator door; an elastic...

Embodiment 2

[0029] In order to further improve the smoothness of the automatic door closing action and increase the effect of automatic door closing, we further form a guide part 3b at the bottom of the refrigerator door 5. For details, see figure 2 as well as image 3 , especially see figure 2 When the guide part 3b and the convex part 2111 are in the first position, they form a matching relationship, so that when the door is closed, the guide part 3b can play an auxiliary role, so that the top convex part 2111 of the pin shaft 21 can better enter the groove 3a ,Such as image 3 as shown in .

Abstract

The invention relates to the field of refrigerators, in particular to a hinge device and a refrigerator with the hinge device. The hinge device used for the refrigerator is disclosed to solve the problems of the prior art that because the closing structure in the form of a clamping hook is adopted for most of refrigerator doors, wear-out failures easily occur and noise is generated. The hinge device comprises a hinge body, a hinge shaft, a hinge sleeve, a door closing unit, a pin shaft, an elastic element and a stopping and blocking piece, wherein a protruding portion is formed at the top end of the pin shaft, the protruding portion is provided with a smooth slope and corresponds to a groove formed in the bottom of a refrigerator door body, the pin shaft is sleeved with the elastic element, the elastic element is located on the hinge body so as to support and guide the pin shaft to move up and down in a through hole, and a guide portion is formed in the bottom of the refrigerator door body and used for guiding the protruding portion at the top end of the pin shaft into the groove. According to the hinge device, the unclosed state of the door body can be well and automatically converted into the closed state in a small distance range, and therefore cool air inside the refrigerator can be effectively prevented from leaking, and the use effect of the refrigerator is ensured.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a hinge device for refrigerators. Background technique [0002] At present, the closing structure of the refrigerator door generally adopts a hook structure, which is easy to wear and fail, and is easy to generate noise. [0003] When closing the door, due to the rebound effect of the sealing strip, the refrigerator door is easy to pop open after closing, and the bounce distance is very small, which is difficult to detect, thus causing the leakage of cold air in the refrigerator. Contents of the invention [0004] The present invention aims at the problem that most of the current refrigerator doors adopt the locking structure in the form of hooks, which are prone to wear and tear, and generate noise. We disclose a hinge device for refrigerators. The refrigerator includes a door body and a box body. Hinge unit includes: [0005] a hinge body, the hinge body is detachably connected...
