Description
Technical field
The present invention relates to a kind of door closer, specifically a kind of refrigerator door closer.
Background technology
Refrigerator common in the market is easy to use, saving energy consumption, is arranged typically at refrigerator door pivot structure
Door closer (company having is backstop) structure, the door closer of current these products is designed directly to hook structure.Such as Chinese patent
Document number CN204027169U in a kind of door holder gear disclosed in 17 days December in 2014, including including door holder gear main body installing plate and
Rotary axle box, with suction structure is helped, also including a limited block, the rigidity of limited block is more than door holder gear master for door holder gear main body installing plate
The rigidity of body, when refrigerator door is opened into maximum angle, contacts spacing by limited block with refrigerator door hinge chain.
During closing the door, hook opens, and absorbs the inertia energy closed the door, and reaches most when closing the door to after certain angle
Big value, will at this time release energy and close door body.Refrigerator door closer hook structure now on the market is more stiff, switch gate
When have pause and transition in rhythm or melody sense, door body can be also flicked sometimes, such as old man, child's strength is smaller, and comparison of closing the door is light, if now close
When the inertia force that door device is absorbed is insufficient to allow door closer to maintain to maximal angle value (plastics hook deformation maximum), door closer
Door body can be flicked on the contrary, and the door body for flicking is likely to hit old man and child.
Therefore, it is further improved.
