Description
Technical field
The present invention relates to refrigerator door technical field, more particularly, to a kind of refrigerator door suction assisting device.
Background technology
Refrigerator often exists when switch gate firmly less can close tight door, or firmly bigger door body resilience is so that closing the phenomenon of not tight door, once refrigerator doors is closed and is not tightly not only resulted in the waste of electricity consumption cold air in casing more can be caused to leak outside, box interior temperature raise thus cause the addling of internal food, rotten.
The switch gate motion of refrigerator is generally the suction assisting device being located at door body and completes, and this suction assisting device is arranged at refrigerator hinge place, and traditional suction assisting device is nylon material, and resilience force at closing time is from the deformation of nylon, and this resilience force is little, thus the door closing force produced is little；From design angle, the resilience force of this suction assisting device generally requires through repeatedly calculating and checking, required time and relatively costly, tradition suction assisting device design simultaneously and the lower section of door body, affects the attractive in appearance of profile.
Summary of the invention
The present invention overcomes at least one defect described in above-mentioned prior art, it is provided that a kind of refrigerator door suction assisting device, and the rotational lock structure of suction assisting device has the auto-lock function locking door body at closing time, and it is reliable to close the door.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of refrigerator door suction assisting device is provided, including an end cap, cover plate and hinge, hinge connects casing and the door body of refrigerator respectively, described door end cap is fixing with door body to be connected, described suction assisting device also includes rotating shaft and shell fragment, described rotating shaft and chain connection, and described shell fragment is connected with door end cap by fixed connection structure, shell fragment is provided with the first backstop groove, and rotating shaft is provided with bulge-structure；
When door body and casing are certain angle, described rotating shaft top pressure shell fragment makes it be deformed, and angle continues to reduce, shell fragment resilience, and the bulge-structure of rotating shaft falls into the first backstop groove, forces rotating shaft and shell fragment locking, it is achieved the locking of door body.
The rotating shaft that rotarily drives of hinge axis at closing time rotates, shell fragment is connected with door end cap by fixed connection structure, thus door body is fixed relatively, when rotating shaft rotation to door body is certain angle with casing, the bulge-structure pressuring spring of rotating shaft makes it be deformed, when angle continues to be reduced to, the rebound effect of shell fragment makes projection fall into the locking reaching the rotating shaft locking with shell fragment and door body and casing in the first stop mechanism.
As preferably, the strip that the bulge-structure that described rotating shaft is provided with is round and smooth is protruding, and this bulge-structure cross section is U-shaped, and the first backstop groove that shell fragment is provided with is U-shaped backstop groove, and U-shaped projection is placed in the effect serving self-locking in U-shaped backstop groove；Rotating shaft can be driven to rotate during force rotary hinge chain rivet, door body and casing angle increase to certain angle, shell fragment stress deformation, namely this U-shaped protruding outside rotating extremely U-shaped retaining groove completes to open the motion of refrigerator door, otherwise, force rotary hinge chain rivet drives rotating shaft to rotate, door body and casing angle are reduced to certain angle, shell fragment stress deformation, and U-shaped projection slips into U-shaped when in groove, door body is closed with casing, completes the self-locking of U-type groove.
As preferably, described hinge is provided with hinge axis, and described rotating shaft is provided with the first through hole, and described hinge axis is placed in the first through hole；
Further, the cross section of described hinge axis is D type, described first through hole is D type hole, described hinge axis is placed in the first through hole, D profile shaft insertion D type hole reaches hole and is connected with being relatively fixed of axle, thus reaching being relatively fixed of hinge and rotating shaft, turning joint can be driven the rotation of rotating shaft by this fixed connection structure.
As preferably, described fixed connection structure includes the second backstop groove being located on shell fragment and the draw-in groove being located on an end cap, and this draw-in groove is provided with block reinforcement and reinforcement, and the one of described shell fragment is placed in draw-in groove, described block reinforcement is placed in the second backstop groove, and reinforcement is placed in outside the second backstop groove；Described second backstop groove is U-shaped backstop groove, and described block reinforcement is spherical block reinforcement, and described reinforcement is the reinforcement of hollow；Shell fragment is in clamped condition together with block reinforcement and reinforcing rib structure by this notch, makes shell fragment and door end cap be relatively fixed, and the second backstop groove serves the effect of spacing clamping.
As preferably, described door end cap and refrigerator door are the structures of one, described door cover internal is provided with the second through hole, it is provided with the first cover rim outside described second through hole, the blind hole being provided with inside described cover plate, described blind hole is provided externally with the second cover rim, and one end of described rotating shaft is placed in the second through hole, the other end is placed in blind hole, and the outside of the second cover rim is sticked in the inner side of the first cover rim；Owing to shell fragment is connected with rotating shaft projection structure, shell fragment is placed in an end cap, hinge arrangement connects door body and casing simultaneously, and hinge axis and rotating shaft are fixedly connected, reach to be fixedly connected with rotating shaft thus hinge axis is the second through hole by door end cap, then extend to cover plate place to match with cover plate blind internal bore, namely the external structure of whole suction assisting device is cover plate and the door end cap composition of Guan Bi, hinge axis is connected through door end cap with suction assisting device internal structure, reaches purpose succinct, attractive in appearance in refrigerator door suction assisting device overall appearance.
Compared with prior art, the invention has the beneficial effects as follows:
First fixed connection structure of refrigerator door suction assisting device of the present invention, the second fixed connection structure and rotational lock structure when being rotated in unlatching refrigerator doors, shell fragment force is deformed by hinge axis, the U-shaped projection in rotating shaft is made to produce U-shaped retaining groove, it is achieved the open operation of refrigerator；When closing refrigerator door, shell fragment being exerted a force, make the U-shaped projection in rotating shaft proceed to U-shaped when realizing auto lock in groove, eliminate and cause because resilience force is less refrigerator door to close the drawback that taut band does not come, self-lock ability is good；Simultaneously the external structure of refrigerator door suction assisting device is mutually clamped by door end cap and cover plate and serves the effect of blocking internal structure, suction assisting device be integrally placed at inside door body, integrally-built succinct and attractive in appearance.
