The elastic component 22 of 1 bottom of chamber door body, the direction end are equipped with the claw 23 that can catch on elastic component 22, the bullet when refrigerator door 1 is opened
Property part 22 be detached from claw 23, when refrigerator doors are closed, elastic component 22 is pressurized interior receipts, progresses into the cavity of claw 23, works as ice
After chamber door completely closes, elastic component 22 is completely embedded into the cavity of claw 23, and realization refrigerator door 1 is close with refrigerator body 3
Closure.
Its shortcoming essentially consists in: 1, elastic component generallys use plastic part and is made, and deformation force is limited, easy to damage, can not
Guarantee its elastic recovery ability with the long period, causes finally cause refrigerator door in effective cooperation of claw 23
23 can not closely be closed to refrigerator body 3, cause energy loss；2, there is biggish resistance when closing and open refrigerator door
Power, operation is not stable enough, and usage comfort is more general.
In order to solve the above-mentioned technical problem, notification number CN106968538B, it is entitled " a kind of refrigerator doors hinge and refrigerator "
Patent of invention, disclose a kind of refrigerator doors hinge, by refrigerator door bottom be arranged spring, conductors, have raised item
The components such as hinge seat, using constituted rising edges between the top of raised item and the upper plane of hinge seat and decline bevel edge,
So that conductors is formed a motion profile on rising edges and decline bevel edge, is opened so as to reach steady control refrigerator door
The purpose closed.
Above-mentioned patent is in refrigerator door opening procedure, and door hinge will drive refrigerator door integral raising, in closing process
In, door hinge will drive refrigerator door and integrally land.In the displacement process that frequent refrigerator door is raised and is landed, it is located at refrigerator
Door body and the gasket fastness of the hinged side of refrigerator body can be destroyed, and sliding can even be fallen off on refrigerator body, for a long time
Use will cause gasket damage, cut with scissors side the problems such as, to influence whether the refrigeration effect and service life of refrigerator.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, refrigerator door energy can not only be guaranteed by providing one kind
It is enough steady comfortable realize to close open, and do not interfere with refrigerator door and refrigerator body hinged side doors strip of paper used for sealing fastness
Refrigerator door closer.
The present invention also provides a kind of refrigerators using above-mentioned refrigerator door closer.
The first aspect of the present invention provides a kind of refrigerator door closer, including be connected to refrigerator door and refrigerator body bottom surface it
Between hinge base, hinge base along its length on successively include refrigerator door pivot region support portion, pedestal interconnecting piece and ice
Box body fixed installation portion, one end is equipped with for being articulated with refrigerator door in the width direction for refrigerator door pivot region support portion
Pin shaft, the other end are equipped with the guidance limiting section of convex state, and guidance limiting section includes the limit positioned at middle part protrusion highest point
Point, the bottom surface of refrigerator door are additionally provided with the lockset opposite with guidance limiting section, and lockset includes can be along the lock of guidance limiting section sliding
Tongue, guidance limiting section between limit point and pedestal interconnecting piece can limit lock tongue and continue to stretch out.
The second aspect of the present invention provides a kind of refrigerator using above-mentioned refrigerator door closer comprising is equipped with above-mentioned refrigerator
The refrigerator door and refrigerator body of door closer.
The present invention is improved by the structure to hinge base, replaces elastic component using lockset, the door closer constituted is not only
Guarantee that refrigerator door can smoothly realize that closing is opened, it may have component long service life, easy to process, manufacturing cost is low
Advantage；Since the door closer is in activity, the reduction of refrigerator door integral raising not will drive, thus to refrigerator door and refrigerator case
The gasket of the hinged side of body does not constitute influence, it is ensured that the using effect of gasket and service life and refrigerator when closed tight
Close property effectively prevents refrigerator cold air caused by damaging because of gasket and leaks.
Detailed description of the invention
Fig. 1 is the assembling structure schematic diagram of door closer described in background technology and refrigerator door and refrigerator body；
Fig. 2, Fig. 3 are structural schematic diagram of the invention；
Fig. 4 is the structural schematic diagram of lockset in the present invention.
Specific embodiment
Referring to fig. 2, a kind of refrigerator door closer provided by the invention, including it is connected to refrigerator door 1 and 3 bottom surface of refrigerator body
Between hinge base 4, hinge base 4 along its length on successively include refrigerator door pivot region support portion 41, pedestal connect
Portion 42 and refrigerator body fixed installation portion 43, one end is equipped with and is used for and refrigerator refrigerator door pivot region support portion 41 in the width direction
The pin shaft 411 that door body 1 is articulated, the other end are equipped with the guidance limiting section 412 of convex state, referring to Fig. 3, guide limiting section
412 include the limit point 413 positioned at middle part protrusion highest point, and the bottom surface of refrigerator door 1 is additionally provided with opposite with guidance limiting section 422
Lockset 5, lockset 5 include can along guidance limiting section 412 slide lock tongue 51, between limit point 413 and pedestal interconnecting piece 42
Limiting section 412 is guided, lock tongue 51 can be limited and continue to stretch out.
Its working principle is that: in conjunction with Fig. 2 and Fig. 3, when opening refrigerator door 1, lock tongue 51 (is located at limit from limit state
When putting the guidance limiting section 412 between 413 and pedestal interconnecting piece 42), it is acted on by manpower, crosses limit point 413(limit point 413
That is lock tongue state for compressing the most in opening and closing), with the gradually unlatching of refrigerator door 1, lock tongue 51 gradually stretches out, industry skill
Art personnel will not be increased and open resistance and be preferred it is contemplated that the stroke of lock tongue 51 can carry out corresponding adjustment as needed；
When closing refrigerator door body 1, lock tongue 51 limits state from extended position or slightly, is acted on by manpower, crosses limit point 413, then into
Enter the guidance limiting section 412 between limit point 413 and pedestal interconnecting piece 42, continued to stretch out by limitation, to complete to lock
It closes.
