The specific embodiment

As shown in Figure 1, in the utility model door of refrigerator hinge, comprise and cut with scissors 4 and Xiamen hinge 7 to the doorstep, cutting with scissors 4 to the doorstep constitutes by cylindrical shell 41 and plate body 42 are integrated, Xiamen hinge 7 also constitutes by cylindrical shell 71 and plate body 42 are integrated, cut with scissors to the doorstep 4 and the plate body 42,72 of Xiamen hinge 7 on be respectively equipped with two or more installing holes 43,73, be respectively applied for by screw or other fastening devices it be installed on the casing 22 and door body 21 of refrigerator, as shown in Figure 2.In the tube hole of upper and lower door hinge, also passed a hinge core 2, the structure of door hinge core 2 as shown in Figure 9, the plate body that makes upper and lower door hinge is around its rotation and reach the free folding of Men Tike in the purpose of casing relatively.

Limit the aperture purpose of opening the door for reaching, the utility model cut with scissors 4 to the doorstep, the Xiamen cut with scissors and be respectively equipped with in 7 cylindrical shells, 41,71 opposing end surfaces in ring platform 44 and 74, on interior ring platform, be respectively equipped with positive stop lug boss 3 and 6, see Fig. 1-Fig. 6, when refrigerator at closing time, two boss 3,6 and door hinge core 2 have angle, about 135 degree, as shown in Figure 3.When opening the door, be fixed on Xiamen on the casing 22 and cut with scissors 7 motionlessly, cut with scissors 4 to the doorstep and rotate around door hinge core 2, cut with scissors 4 boss 3 to the doorstep and do circular motion along encircling 74 formation tracks of platform in door hinge cores 2 and the Xiamen hinge, walk to the boss 6 of Xiamen hinge 7, be limited stroke, as shown in Figure 4.

For realizing that a door body detachably be a left and right opening door, in also being symmetrically arranged with, the relevant position of the other end of upper and

lower door hinge

4 and 7 encircles platform and boss, as shown in Figure 5 and Figure 6.When adopting the left side to open the door, 4 the B face of cutting with scissors to the doorstep among Fig. 1 contacts with the C face of Xiamen hinge 7, make that cutting with scissors 4 positive stop lug boss 3 to the doorstep can cut with scissors in the orbit space that 7 interior ring platform 74 and door hinge core 2 form along the Xiamen and rotate, to cut with scissors between the positive stop lug boss 3 position definite with cutting with scissors door in 4 to the doorstep for the door hinge positive stop lug boss 6 in its slewing area and the Xiamen hinge 7.When needing the right to open the door, the door hinge is contained in the left side, cutting with scissors 4 A face and Xiamen to the doorstep, to cut with scissors 7 D face relative, can realize same limit function.For reaching purpose attractive in appearance, as shown in Figure 1, also be provided with door hinge cap 1 as shown in Figure 7, be sleeved on and cut with scissors 4 tops to the doorstep and 7 bottoms are cut with scissors in the Xiamen.For making a hinge when rotating, be unlikely to wearing and tearing, also be provided with as shown in Figure 8 a door hinge pad 5 two hinge centres of 4 and 7, pad 5 is except being used to pass the through hole 52 of hinge core 2, also has a looping pit 51, the angle of its looping pit can cooperate the aperture of opening the door, for example 135 spend, so that boss is done circular motion in above-mentioned looping pit when the open and close door.
