The specific embodiment
As Fig. 1 to Fig. 3, the utility model built-in refrigerator hinge, comprise internal fixation plate 1, outer fixed head 2, and the interior fork 3 and the outside lever 4 that connect internal fixation plate 1 and outer fixed head 2, internal fixation plate 1 is installed on the refrigerator tank wall, and refrigerator doors is fixed on the outer fixed head 2, and interior fork 3 and outside lever 4 are used to realize the main motion of mechanism, interior fork 3 is connected with internal fixation plate 1 by the first interior fork axle 6, is connected with outer fixed head 2 by the second interior fork axle 7; Outside lever 4 is connected with internal fixation plate 1 by the first outside lever axle 8, is connected with outer fixed head 2 by the second outside lever axle 9; Connect by extension spring 5 between described internal fixation plate 1 and the interior fork 3, an end of extension spring 5 is fixed on the internal fixation plate 1, and the other end is fixed on the interior fork 3.
One end of extension spring 5 is fixed on the first spring sheath 10, and the other end is fixed on the second spring sheath 11, and the first spring sheath 10 is fixed on the internal fixation plate 1, and the second spring sheath 11 is fixed on the interior fork 3.Be provided with a groove in the middle of the first spring sheath 10 and the second spring sheath 11, recess width is less than 3mm, and depth of groove is less than 1mm.The pretightning force that has 5-15N under the state of door body closure provides the stability force of certain maintenance door opening state, the about 18-28N of stability force under maximum open angle.Tensile force when being fixed in the spring minimum stroke of the first spring sheath 10 and the second spring sheath 11 is between 90-150N.
The utility model built-in refrigerator hinge can be realized the stable state of closing the door after a body is opened stable door opening state behind the certain angle and door body and closed, these two stability margins that the state tool is certain need the certain power of opening the door and door closing force just can make its change state.When the door body is closed since interior fork 3 tightly the outer fixed head 2 of pulling is close to casing under the effect of extension spring 5 pulling force, and keep certain pretightning force, guarantee a stability of body closure; When the door body is opened, the pulling force of extension spring 5 is increasing, after the door body reaches certain angle, the end face 23 of interior fork 3 is tangent with the end face 44 of outside lever 4, cause inside and outside fork to be in contact with one another to have an effect and produce self-locking, thereby make a body be fixed on certain opening angle, maximum opening angle is within 100 °, as Fig. 5.
Internal fixation plate 1 is stamped into the shell shape of U font for the center line symmetry, its top has strip slot and pass groove, its two sides have 3 through holes 12,13,14, the first spring sheath 10 is installed in one of them through hole 12, fork axle 6 is fixed in second through hole 13 in first, and the first outside lever axle 8 is fixed in the 3rd through hole 14; The distance of the bottom surface 20 of the center line of through hole 12 and internal fixation plate 3 is less than 10mm.Wherein the distance between the through hole 13 of the through hole 10 of mounting spring sheath 10 and the installation first interior fork axle 6 is less than 20mm.
Outer fixed head 2 is stamped into the shell shape of U font and the combination of L font, has two through holes 15,16 in the both sides of U font part, and the air line distance between through hole 15,16 center lines is less than 20mm.Fork axle 7 is fixed in the through hole 15 in second, and the second outside lever axle 9 is fixed in the through hole 16; In described fork 3 one ends around the through hole 13 that is fixed in internal fixation plate first in fork axle 6 rotate, the through hole 15 of other end fixed head 2 outside being fixed in second in fork axle 7 rotation, outside lever 4 one ends are around the first outside lever axle, 8 rotations of the through hole 14 that is fixed in internal fixation plate, and the second outside lever axle 9 of the through hole 16 of other end fixed head 2 outside being fixed in rotates.
Fig. 4 is the fundamental diagram of the utility model refrigerator doors hinge, AC is interior fork 3 among the figure, DC is outer fixed head 2, BD is an outside lever 4, EF is an extension spring 5, extension spring 5 produces tensile force always, internally fork 3 produces clockwise moment always, therefore work as interior fork 3 and before the C point is not crossed outside lever 4 dead points, do folding, the refrigerator doors closure, after the C point passes through outside lever 4 dead points, the clockwise moment of interior fork 3 forces outer fixed head 2 to produce two power bar effects, and this two power bar effect forces outside lever 4 to be done and turns clockwise, and it is that refrigerator doors is launched that outer fixed head 2 also turns clockwise, and because the rotational angular velocity of outside lever 4 is faster than interior fork 3, so outside lever 4 finally is in stable self-locking under the stopping of interior fork 3.
Fig. 5 and Fig. 6, interior fork 3 is a U type fork shape, one end is forked, one boss 24 is arranged on the interior fork 3, fork 3 is offered 3 through holes 17,18,21 altogether in whole, and wherein through hole 17 is positioned on the boss 24, the first interior fork axle 6 and first through hole 17 assemblings, fork axle 7 and second through hole 18 assembling, the second spring sheath 11 and the 3rd through hole 21 assemblings in second.
Fig. 7 to Figure 10, outside lever 4 is " protruding " word shape, and projection is longer, and its thickness is less than the U type well width of interior fork 3, so that can be by the U type groove of interior fork 3, outside lever 4 two ends be respectively equipped with two through holes 19,22 that the first outside lever axle 8 and the second outside lever axle 9 are installed.
Fig. 7 and Fig. 8 are a kind of structure of outside lever, and outside lever 4 end faces of both sides 44 are arc surface.
Fig. 9 and Figure 10 are the structure of another kind of outside lever, and outside lever 4 end faces of both sides 44 are the inclined-plane, and the angle of the axial line of itself and outside lever 4 is 18 ° ~ 25 °.
