The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figure 1 and Figure 2, a kind of refrigerator doors self-locking limiting device that present embodiment provides, comprises hinge 1 and positioner 2, wherein, is provided with self-locking projection 11 on hinge 1; Positioner 2 comprises positioning convex 213, and the elastic arm 212 being connected with positioning convex 213, and the positioning convex 213 that is connected with elastic arm 212 is realized the self-lock turning off of refrigerator doors and freely opens by matching with self-locking projection 11.
On hinge 1, be also provided with limited impression 12, on positioner 2, be provided with limited impression 12 and coordinate the location division 221 that limits the maximum opening angle of refrigerator doors.
Concrete, under refrigerator doors is closed the door state, above-mentioned self-locking projection 11 and positioning convex 213 lock mutually, can realize the locking of refrigerator doors, prevent that the closed phenomenon that does not tightly occur cold draining from appearring in refrigerator doors, simultaneously in the unlatching of refrigerator doors, closing process, because the effect positioning convex 213 of elastic arm 212 can not impact the proper motion of refrigerator doors.In the opening process of refrigerator doors, by the mutual engaging of limited impression 12 and location division 221, can limit the maximum opening angle of refrigerator doors, this maximum opening angle is determined according to the use habit of most people.
More specifically, above-mentioned positioner 2 comprises door closer 21 and door closer backstop 22.
Wherein: door closer 21 comprises fixed part 211 and elastic arm 212, one end of elastic arm 212 is connected with fixed part 211, its other end is provided with positioning convex 213, as preferably, elastic arm 212 is made up of elastomeric material, or by being equipped with on fixed part 211 of spring and rotating shaft, can there is elastic deformation or rotation to realize elastic arm 212 in refrigerator door open-close process, can normally not opening and impacting refrigerator doors to realize positioning convex 213.
Location division 221 is arranged in door closer backstop 22, and the side that door closer backstop 22 has a location division 221 has curve slope; One end that hinge 1 has limited impression 12 has circular arc projection, and in refrigerator doors opening procedure, curve slope can be free to slide along circular arc projection.
In door closer 21 and door closer backstop 22, all there is installing hole, and be connected with refrigerator doors 4 by the screw through installing hole.
Certainly, as preferably, door closer 21 and door closer backstop 22 are integral type structure.The door closer 21 of integral type and door closer backstop 22 can facilitate both installation and manufactures, can effectively save and manufacture and installation cost.
Because door closer 21 is elastic construction, therefore door closer 21 is made for plastic material, and preferred, door closer 21 is made by having flexible plastic material.Door closer backstop 22 need to be carried out refrigerator doors spacing, and it needs certain structural strength.Therefore, door closer backstop 22 is made for carbon steel material.
As preferably, self-locking projection 11 and positioning convex 213 are arc structure.
For above-mentioned refrigerator doors self-locking limiting device is further explained, the application also provides its concrete installation and working method.
Hinge 1 is screwed on casing 3, door closer 21 is plastic material products, door closer backstop 22 is carbon steel products, and it is coaxial with the installing hole in door closer backstop 22 to be positioned at door closer 21, passing the coaxial installing hole of two products with screw is fixed on refrigerator doors 4 bottom end covers, when refrigerator doors 4 is during around hinge axis rotary closing, the positioning convex 213 of door closer 21 slides along self-locking projection 11 edges of hinge 1, when refrigerator doors 4 and casing 3 attach while closing completely, the elastic arm 212 of door closer 21 produces plastic strain makes positioning convex 213 cross the high high spot of the self-locking projection 11 of hinge 1.Meanwhile, positioning convex 213 fastens mutually with self-locking projection 11, forms the self-locking of refrigerator doors.If need to open refrigerator doors 4, must apply external force positioning convex 213 is out of shape, so refrigerator doors 4 realizes self-locking after closing.Refrigerator doors 4 is around hinge axis Unscrew, and the curve slope of door closer backstop 22 slides along the arc convex of hinge 1, mutually engages and realizes door open limit with limited impression when closing when location division 221 on door holder gear 22 moves to limited impression 12 place.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present utility model, within these modes all will fall into protection domain of the present utility model.
