Description
Technical field
The invention belongs to hinge technical field, specifically, is related to a kind of door closing hinge with damper.
Background technology
Refrigeration class household appliances with hollow glass door, because door body weight itself is big, when closing the door, door body is to case
The impact of body is very big, causes the vibration of complete machine and noise at closing time, very unfavorable to the product stored in cabinet, particularly wine cabinet class
Deng the product of storage red wine.When storing red wine to ensure that the quality of red wine needs relatively quiet stable storage condition, and open
Sharp pounding can influence the quality of red wine at closing time；The refrigeration appliance that family uses, because momentum is big, when door body is closed automatically
Bigger power can be produced, is even more such as especially to children and old man if paying no heed to the danger for having and crushing hand and head
This.
The big multipotency of door closing hinge realizes automatic door-closing function used by the glass door in refrigeration appliance at present, but automatically
The widely used Spring driving structure of door closing hinge is during door body closure is driven, due to the work of lasting flexible power
With causing the rotating speed of door body around hinge axle persistently to increase, door body is produced strong impact in closure moment and casing.
The content of the invention
The invention provides a kind of door closing hinge with damper, by increasing damper in door closing hinge, is closing the door
During door closing hinge be damped the damping action of device, the rotating speed of door body around hinge in closing process is controlled, so as to avoid
Impact and vibration, improve life staying idle at home quality caused by door body closure moment.
In order to solve the above technical problems, the present invention is achieved using following technical scheme：
A kind of door closing hinge with damper, including housing, the lower housing portion are provided with hinge axis, the hinge axis top
Stop configurations force closure cam structure and hydraulic damper are provided with enclosure interior；
The force closure cam structure includes translating cam, rotation cam and spring, the rotation cam lower end and hinge
Axle is integral type structure；I.e. the lower end of rotation cam is as hinge axis；
The hydraulic damper includes hydraulic cylinder, ring flange, piston and piston rod, and the piston is provided with damping hole, institute
State hydraulic cylinder and ring flange is fixed in housing, hydraulically full inside hydraulic cylinder, the piston is located in hydraulic cylinder；
The spring is between ring flange and translating cam, and both ends of the spring connects with ring flange and translating cam respectively
Connect；
The piston rod is connected downward through after ring flange, spring with translating cam successively.Piston rod plays guide effect.
Further, the hinge axis top is provided with stop configurations in enclosure interior, and the stop configurations include hinge axis
With the stop block on housing, the stop block on hinge axis is located at the lower end of rotation cam, and the stop block on housing is located in housing
Bottom of chamber portion.
Further, the translating cam and the faying face of rotation cam are gradual change convex surface.In rotation cam rotary course
In, translating cam can be moved up by active force.
Further, it is all provided with fluted on the ring flange and translating cam, the both ends of the spring are respectively embedded into groove
Middle positioning, only need to position, without affixed.
Further, the hydraulic cylinder top is connected with housing by screw or pin.
Further, the ring flange is adhesively fixed with hydraulic cylinder lower end or is fixedly connected by screw.
Further, it is fixedly connected between the piston-rod lower end and translating cam by screw.
Further, the shell cavity inwall be provided be oriented to groove, the ring flange and translating cam it is cylindrical
It is provided with corresponding guide pad week.
A kind of vertical refrigeration appliance, using the above-mentioned door closing hinge with damper.
The vertical refrigeration appliance refers to one kind in vertical freezer, vertical refrigerator or vertical wine cabinet.
Rotation cam, translating cam and spring collectively form force closure cam structure, refer to when opening the door, hinge axis rotation
Rotation cam rotation is driven, translating cam can be moved up by active force, be compressed spring；When no external force acts on
After the door body of opening, spring can downward diastole automatically, spring force driving translating cam move down so as to drive rotation cam to rotate, with
Realize automatic door-closing function.
And hydraulic damper plays damping action, when opening the door, translating cam moves up, and drives piston rod and piston
Move up, be now placed in the liquid in upper piston area hydraulic cylinder and enter through damping hole in the hydraulic cylinder cavity body of piston lower portion；And certainly
In dynamic door closing procedure, when translating cam moves down, drive piston rod and piston to move down, force positioned at piston lower portion
Liquid in hydraulic cylinder enters through damping hole in the hydraulic cylinder cavity body of upper piston area, therefore liquid in hydraulic cylinder and damping hole exist
Damping action is played in door body closing process.
The present invention is by setting damper and stop block in door closing hinge, door closing hinge of the composition with damping and backstop,
By the open angle limitation of door body within the specific limits, and door body is realized slowly closing during closing, reduce to case
The impact of body and caused noise, while reduce the vibration of cabinet, improve security performance.
Compared with prior art, the advantages and positive effects of the present invention are：
1st, refrigeration appliance realizes the unification of automatic door-closing and damping action, will not occur door body suddenly close impact and
The phenomenon of vibration；
2nd, the article to ambient vibration condition responsive can be improved（Such as red wine）Hoarding effect；
3rd, effectively avoid door body from closing suddenly and cause the hidden danger that crushes hand and head, particularly with children and old man；
4th, without very big difference, door body structure does not have to make very big change the hinge with existing vertical refrigeration appliance.
