Embodiment
Referring to Fig. 2, a kind of refrigerator doors hinge provided by the invention, including checkpost 4 under refrigerator door, checkpost under refrigerator door
4 one end is provided with downward opening first axle axle limit chamber 5, and the lower horizontal of checkpost 4 is provided with hinge seat 6 under refrigerator door,
One end of hinge seat 6 is provided with hinge axis 7 along the vertical direction, and with reference to Fig. 3, the bottom surface of checkpost 4 is put provided with door closer under refrigerator door
Chamber 8 is put, door closer 9 is embedded in door closer placed cavity 8, and referring to Fig. 2, one end of door closer 9 is provided with the downward opening second hinge
Chain rivet limit chamber 10, the top of hinge axis 7 penetrate second hinge axle limit chamber 10 and with the freedom in lumenal levels rotation
Degree, second hinge axle limit chamber 10 penetrate and spacing in first axle axle limit chamber 5, and checkpost 4 is fixed on ice under refrigerator door
The bottom of chamber door body 1, during opening and closing, hinge seat 6 keeps fixing, first axle axle limit chamber 5 and second hinge axle limit chamber 10
Rotated around hinge axis 7, to realize the be hinged of refrigerator door 1 and refrigerator body 3, in order to ensure that refrigerator door can be steadily comfortable
Realization close and open, and make hinge arrangement at this that there is longer service life, referring to Fig. 4, hinge seat 6 of the invention
On, raised item 11 is longitudinally provided with the horizontal relative one end in the position of hinge axis 7, the top of raised item 11 is put down with the upper of hinge seat 6
Rising edges 12 are formed between face with declining hypotenuse 13, referring to Fig. 5, under door closer 9 and refrigerator door the bottom of checkpost 4 be provided with
The guiding groove 14 that the shape of raised item 11 is adapted, conductors mounting hole 15 is provided with the guiding groove 14 of door closer 9, with reference to Fig. 6,
Conductors include top guide 16 and guide rod 17, and top guide 16 is located in conductors mounting hole 15, and conductors mounting hole 15 is provided with anti-
Only top guide 16, which falls, departs from the stopper slot 19 of conductors mounting hole 15, and referring to Fig. 2, checkpost 4 is provided with opening court under refrigerator door
Under conductor limit chamber 20, guide rod 17 is located in conductor limit chamber 20, and spring 21, spring are arranged with referring to Fig. 6, outside guide rod 17
21 upper limit is spacing on top guide 16 in the inner roof wall of conductor limit chamber 20, bottom.In the fully open state of refrigerator door 1
Under, top guide 16 is supported in conductors mounting hole 15 naturally, and with progressively closing off for refrigerator door 1, top guide 16 touches hinge
The planar section of seat 6, afterwards with the continuous extruding of rising edges 12, when at the vertex position of raised item 11, it is squeezed into
The highest position of conductors mounting hole 15, the spring 21 on guide rod 17 are compressed to most tight state in conductor limit chamber 20,
Top guide 16, which is gradually moved to, afterwards declines hypotenuse 13, declines between hypotenuse 13 and the vertex position of raised item 11, forms one and lead
First 16 support chamber, now the spring 21 on guide rod 17 unfold (not up to most deployed condition), top guide 16 is supported on support chamber, refrigerator
Door body 1 is now realized and completely closed.Because the summit position by raised item 11 is limited, so in the case where not stressing,
Refrigerator door 1 will not automatically turn on, and ensure that tightness and stability of the refrigerator door after closing；Additionally by raised item
11st, rising edges 12 coordinate telescopic conductors to set with declining hypotenuse 13, and conductors can be in rising edges 12 and lower drop angle
A movement locus is formed on side 13, it can be ensured that the smoothness of running, and the elastic deformation of top guide 16 is more
Small, each component can ensure that it possesses a longer service life without larger abrasion.
Further, since the refrigerator door direction of motion is horizontal direction, and door body closes spacing direction in vertical direction, with door
The body direction of motion is not in a direction vector.So the motion of same parts Same Latitude can be avoided and spacing be likely to occur fortune
Dynamic state labile situation.
In the present embodiment, referring to Fig. 2, the bottom of door closer 9 is vertically provided with spacing card article 22, the front of hinge seat 6 and
Side offers space retaining groove 23.Purpose is, for limiting the opening and closing angle of refrigerator door 1, when spacing card article 22 it is spacing
It during 6 space retaining groove 23 in front of hinge seat, can prevent from closing in the continuation of refrigerator door, when effort to close is larger, prevent from causing
Impact to refrigerator body；When spacing card article 22 it is spacing in the space retaining groove 23 of the side of hinge seat 6 when, can prevent refrigerator door from opening
Angle is opened more than 90 degree, causing the damaged in collision of refrigerator door and its obstacle (when refrigerator particularly being put into corner, prevents out
It is excessive to open angle, and is collided with wall).
In the present embodiment, referring to Fig. 7, the bottom surface of top guide 16 is oblique arcwall face, and 6 angle of inclination in front of hinge seat facing forward is big
In the angle of inclination towards the back of hinge seat 6 facing forward.Purpose is, when refrigerator door is opened, has larger angle of inclination
Oblique arcwall face, big with the contact area of rising edges 12, top guide 16 steadily rises during movement transitions, without using larger
Strength just can open refrigerator door；After refrigerator door is opened, the small face in angle of inclination hinders declining at hypotenuse 13, by
Be in contact with it that area is small, volume is big in top guide 16, can play a part of it is certain prevent refrigerator door from closing automatically, be operation effect
Fruit is more reliable.
In the present embodiment, referring to Fig. 8, top guide 16 includes oblique lower arcuate surface 161 and semi-circular top surface 162, and stopper slot 19 is in
It is step-like, set along the periphery of conductors mounting hole 15, semi-circular top surface 162 is spacing on the step, and oblique lower arcuate surface 161 is worn
Enter in conductors mounting hole 15.Using this kind of design structure, it can be ensured that for refrigerator door 1 in upset, top guide 16 will not be due to
The support of disengaging hinge seat 6, and the phenomenon to drop, limit certain travel displacement, have the high spy of structural stability
Point.
In the present embodiment, the manufacture material of guide rod 17 is polyformaldehyde (POM).Compare most with door closer in the prior art
The teflon material of use, polyformaldehyde have high fatigue strength, resistance to repetitiousness impact, self lubricity, wearability.As leading
After body part use, the service life of whole mechanism is improved.
In the present embodiment, the manufacture material of door closer 9 is the nylon material that PA66 nylon synthesizes with glass fibre.Using this
The door closer of kind material coordinates guide rod, and not only door closer itself has preferable mechanical property and mechanical strength, and and guide rod
Between coefficient of friction it is also smaller, also possess good self-lubricity, make at this operating structure more reliable and stable and with higher
Service life.
The present invention also provides a kind of refrigerator using above-mentioned refrigerator doors hinge, and it includes being provided with above-mentioned refrigerator doors hinge
Refrigerator door 1.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
