The specific embodiment
Embodiments of the invention will describe with reference to accompanying drawing.In Figure of description, the element with similar structures or function will be used the components identical symbolic representation.Accompanying drawing is not to carry out the explanation of exhaustive to the present invention just for the ease of each embodiment of the present invention is described, neither limit scope of the present invention.
Fig. 1 to Fig. 6 has provided an embodiment of the utility model.In this embodiment, refrigerator comprises chamber door 1, and casing 2, chamber door are provided with handle 11, and handle 11 flexibly connects with chamber door 1, relatively the chamber door move left and right.In one embodiment, chamber door handle and chamber door simultaneously through some stopping means (scheming not shown), make the chamber door handle in certain angle, to rotate around pivot for articulating.Those skilled in the art will appreciate that and anyly can make the setting of the relative chamber door of chamber door handle move left and right in certain scope all can bring use.Refrigerator top is provided with a locking device, and locking device comprises a lug boss 21, a lever arm 3 and a spring 4 at least.
Lug boss 21 is arranged on casing 2 tops, and in one embodiment, lug boss 21 is cylindric, and its outer surface is an arc surface.Door of refrigerator 2 tops are provided with lever arm 3, and this lever arm 3 has a first end 31, a second end 33 and a middle part 32, and the door of said middle part 32 and chamber door 2 is along being rotatably connected through a pivot, make the lever arm 3 can be in the chamber door upper edge around the pivot rotation.It is last that pivot can be arranged on an edge, and lever arm middle part perforate and hinge cooperate.Equally, hinge can be arranged on the middle part of lever arm, and door cooperates along the hinge on last perforate or groove and the lever arm.Lever arm first end 31 is connected with chamber door handle 11.In one embodiment, lever arm first end 31 is rotatably connected through a pivot with chamber door handle 11, and in other embodiments, lever arm first end 31 can be fixedly connected with welding or the mode of pasting with chamber door handle 11.It is one hook-shaped that lever arm the second end 33 is, and its shape and lug boss 21 shapes adapt.Door of refrigerator 1 is when closure, and lever arm the second end 33 can hook lug boss 21.
When door of refrigerator 1 was in the complete opening state, the user needn't continue the application of force to be held open to chamber door.
Referring to Fig. 5; When outer convex surface 331 is under the semi-closed state and trends towards closure at chamber door; Agree with to make the lever arm the second end be moved to the left mutually with lug boss 21, lug boss 21 finally slips into lever arm inner concave 332 by the outer convex surface 331 of lever arm with the contact-making surface of lever arm the second end.
Referring to Fig. 6, inner concave 332 hooks lug boss 21, guarantees the good seal of door of refrigerator and casing.When the user attempted to open door of refrigerator, hand-held handle 11 is the application of force to the right, and lever arm first end 31 moves right, and 33 of lever arm the second ends are moved to the left thereupon, and like this, inner concave 332 is thrown off with lug boss 21, thereby the user opens chamber door easily.In fact, the user when opening the door, need not be painstakingly with handle 11 application of force to the right, have the enough component of vector to the right then can as long as guarantee to the active force of handle 11.
Fig. 7 is the locking device enlarged drawing under another embodiment of the utility model refrigerator.In this embodiment, the lateral surface of lug boss 21 is sharp-pointed outer convex surface, and the inner concave 332 of lever arm the second end is sharp-pointed inner concave, and the outer convex surface 331 of lever arm the second end still is a smooth surface.Under this embodiment, lever arm the second end inner concave 332 has an inner concave root 333, and inner concave root 333 should keep smooth arc surface excessive, causes the lever the second end to rupture easily to avoid material surface stress to concentrate.
It will be appreciated by those skilled in the art that; The outer convex surface of the lateral surface of lug boss 21 and lever arm the second end and the Any shape between the inner concave cooperate; As long as can lock in the time of reaching the chamber door closure; When chamber door was semi-closed, the contact-making surface of lug boss 21 and lever arm the second end can be slipped into the purpose of lever arm inner concave 332 by the outer convex surface 331 of lever arm, can bring use.
Simultaneously; Door locking device can be arranged on door of refrigerator upper edge and lower edge simultaneously, also can door locking device only be arranged on the chamber door upper edge, and chamber door handle lower end and chamber door articulate simultaneously; Perhaps door locking device is arranged on the chamber door lower edge, chamber door handle upper end and chamber door articulate simultaneously.
More than though the specific embodiment of the utility model has been described, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
