A kind of refrigerator hinge
Technical field
The present invention relates to a kind of transmission parts of hinge, specifically a kind of refrigerator hinge.
Background technology
Refrigerator hinge is presently the most common refrigerator door rotating opening connector, in order to realize that refrigerator door is being beaten
On or off can have good closing performance between refrigerator cabinet after closing, existing refrigerator hinge would generally use six-bar linkage to pass
Motivation structure.However, traditional refrigerator hinge has the following disadvantages:1. elastic buffer is set in rear transmission arm, by hinged seat
On boss push the work forward, when the rotation of rear transmission arm, the shaft of boss is in stationary state always, to make bullet when top pressure spring
Spring is influenced by radial stress, is susceptible to the radial deformation of spring, and unbalance stress;2. cylinder formula buffer is all disposed on
In one transmission arm, the piston rod of cylinder formula buffer and the fixing end of cylinder body will produce rotation torque, make piston rod and piston by diameter
To stress influence, phenomena such as being susceptible to unbalance stress, deformation, damage;3. locating plate and fixed seat are all separate type settings, Gu
Reservation can be just fixed in refrigerator framework by locating plate, and not only assembly process causes efficiency of assembling low more, and is difficult to
Ensure assembly intensity, and may loosening be generated due to error, influences to use and embody;4. the arm of force of hinge seat rotation is less, lead
Cause refrigerator door rotation needed for thrust it is larger, be not easy to operate, the connection basic point of hinge inner is more, be easy to cause steam,
The accumulations such as dirt.Therefore, traditional refrigerator hinge is still up for further improving.
