Description
Technical field
The present invention relates to household appliance technical field, more specifically, relate to a kind of door body self-locking device, and there is the refrigerator of this body self-locking device.
Background technology
Door part of refrigerator and electric refrigerator housing body adopt chain connection to realize free-open-close, the self-locking manner at present with the refrigerator of auto-lock function is divided into two kinds, be install a magnetic stripe in the door seal of refrigerator, being attracted each other by magnetic stripe realizes self-locking, but magnet can reduce the heat-insulating property of door seal.Another kind is on refrigerator, install door body self-locking mechanism, although this mode can ensure the heat-insulating property of refrigerator, but limit by the locking pin of self-locking mechanism and snap close (as shown in Figure 1) structure, door body self-locking mechanism only can at closing time for user provides power-assisted, and power-assisted can not be provided when opening the door, user can be felt, and the process of whole enabling compares effort, and the use sense reducing user is subject to.
Summary of the invention
The present invention is intended to solve in prior art the technical problem that exists one of at least.
For this reason, one object of the present invention is, provide a kind of can when opening the door for user provides the door body self-locking device of power-assisted.
Another object of the present invention is, provides a kind of refrigerator, comprises above-mentioned door body self-locking device.
For achieving the above object, the embodiment of first aspect present invention provides a kind of door body self-locking device, for refrigerator, the door body of described refrigerator and casing are connected through the hinge, comprise: described hinge, described hinge is provided with locking pin and is in the spring of extended state all the time, the first end of described locking pin is rotatably connected with described hinge, second end of described locking pin is provided with the first connecting portion, the first end of described spring and described chain connection, second end of described spring is connected with the position on described locking pin except the first end of described locking pin, described spring can drive described locking pin to rotate, described hinge is provided with the limited block for limiting the described locking pin anglec of rotation, snap close, is fixedly mounted on described door body, described snap close is provided with the second connecting portion, and described second connecting portion can coordinate with described first connecting portion, wherein, the orthographic projection that is positioned at described locking pin of the first end of described spring and the link position of described hinge with described locking pin to be rotated on described hinge process region outside.
Door body self-locking device according to an embodiment of the invention, door body self-locking device comprises snap close and hinge, and snap close is fixedly mounted on the door body of refrigerator, and snap close is provided with the second connecting portion, the door body of refrigerator and casing are connected through the hinge, and hinge is arranged on the top of refrigerator and/or the bottom of refrigerator.Wherein, described hinge is provided with locking pin, the first end of locking pin is rotatably connected with hinge, second end is provided with the first connecting portion, first connecting portion can coordinate with the second connecting portion, to make locking pin and snap close allotment of labor do, thus the door body of refrigerator is fastened or is opened, adopt this locking mode not need, in the door seal of refrigerator, magnetic stripe is installed, ensure that the heat-insulating property of refrigerator.Hinge is also provided with spring, the first end of spring and chain connection, the second end is connected with the position on locking pin except the first end of locking pin, and spring is in extended state all the time.Spring drives locking pin to rotate at open and close Men Shike, for user provides power-assisted, hinge is also provided with the limited block of the restriction locking pin anglec of rotation.
Wherein, when door body opens to the first predetermined angle, first end, the second end 4 conllinear of the first end of locking pin, the second end and spring.The orthographic projection being positioned at locking pin due to the first end of spring and the link position of hinge with locking pin to be rotated on hinge process region outside, when the angle that a body is opened is less than the first predetermined angle, the pulling force of spring can drive locking pin to be rotated in a clockwise direction, when the angle that door body is opened is greater than the first predetermined angle, the pulling force of spring can drive locking pin to rotate in the counterclockwise direction.
Particularly, when door body is closed, the first connecting portion and the second connecting portion are in connection status, the pulling force of spring passes to snap close by locking pin, snap close is born towards the active force in casing direction, thus a body is tightly covered on casing, avoid a body to cover not tight problem and occur.During enabling, first connecting portion and the second connecting portion are in connection status, snap close rotates with door body, locking pin rotates under the drive of snap close, after door body opens to the first predetermined angle, continue to expand open angle, the pulling force of spring can drive locking pin to rotate in the counterclockwise direction, for user provides enabling power-assisted, thus the use sense improving user is subject to; Door body is when opening to the second predetermined angle, the first connecting portion and the second coupling part from, locking pin and limited block are conflicted simultaneously, and prevention locking pin continuation rotation, to limit the position of the first connecting portion; Continue to expand open angle, door body is no longer by the impact of door body self-locking device.At closing time, when door body closes to the second predetermined angle, the first connecting portion is connected with the second connecting portion, continues to reduce angle of closing the door, and snap close drives locking pin to rotate; When door body closes to the first predetermined angle, continue to reduce angle of closing the door, the pulling force of spring can drive locking pin to be rotated in a clockwise direction, and for user provides power-assisted of closing the door, thus the use sense improving user is subject to, and now door body self-locking device can the self-locking of driving gate body.
