1-Fig. 3 describes the hinge 100 for refrigerator according to the embodiment of the present invention in detail with reference to the accompanying drawings.
As Figure 1-3, according to the hinge 100 for refrigerator of the embodiment of the present invention, comprising: base 10, Connection Block 20, the first pivotal axis 30, the second pivotal axis 40, guide rod 50, supporting seat 60, location division 70, spring protecting sleeve 80 and spring 90.
Particularly, the left side of base 10 is provided with the first turn-up portion 11, and the right side of base 10 is provided with in the second turn-up portion 12, the first turn-up portion 11 relative with the first turn-up portion 11 and the second turn-up portion 12 and is relatively set with chute 13, and for example, it is circular-arc that chute 13 can be.The left side of Connection Block 20 is provided with three turn-up portion 21 adjacent with the first turn-up portion 11, and the right side of Connection Block 20 is provided with four turn-up portion 22 adjacent with the second turn-up portion 12.Thus, be convenient to the first pivotal axis 30 and the second pivotal axis 40 to be assembled on base 10 and Connection Block 20.
The first pivotal axis 30 is located at the upper end of base 10, and the left end of the first pivotal axis 30 is connected with the first turn-up portion 11 and the 3rd turn-up portion 21 pivotables, and the right-hand member of the first pivotal axis 30 is connected with the second turn-up portion 12 and the 4th turn-up portion 22 pivotables.The second pivotal axis 40 is parallel with the first pivotal axis 30, the left end of the second pivotal axis 40 is connected with the 3rd flange, right-hand member is connected with the 4th flange, and the interior slip of chute 13 in the first turn-up portion 11 and second turn-up portion 12 of correspondence respectively of the two ends of the second pivotal axis 40.
Supporting seat 60 is located at the lower end of base 10, and the upper end of guide rod 50 is connected with the second pivotal axis 40 pivotables, through hole 61 on the supporting seat 60 that the lower end of guide rod 50 is passed.Guide rod 50 is provided with location division 70, and spring protecting sleeve 80 is set on guide rod 50 and can between location division 70 and supporting seat 60, moves.
Spring 90 is set on spring protecting sleeve 80, and the lower surface of the upper end of spring 90 and location division 70 offsets, the upper surface of the lower end of spring 90 and supporting seat 60 offsets, and spring 90 is more than or equal to spring protecting sleeve 80 along the height on its axial direction along the height on its axial direction.Be understandable that, spring protecting sleeve 80 can effectively prevent that spring 90 is towards the direction bending that departs from guide rod 50 center lines, avoids directly contacting and producing friction noise with guide rod 50 because of spring 90.
According to the hinge 100 for refrigerator of the embodiment of the present invention, by spring protecting sleeve 80 being set between guide rod 50 and spring 90, can effectively prevent that spring 90 is towards the direction bending that departs from guide rod 50 center lines, avoid directly contacting and producing friction noise with guide rod 50 because of spring 90, thereby promote the performance of product, improved user's satisfaction.
Consider that spring 90 has certain application life, in use for some time, spring 90 easily produces fatigue failure, and now the elastic force of spring 90 can weaken.The problem weakening because of the tired elastic force producing in order to overcome spring 90, in concrete examples more of the present invention, guide rod 50 can be cylinder guide, cylinder guide is provided with external screw thread (scheming not shown), location division 70 can for the nut being threaded with guide rod 50, for example, be hex nut.Thus, can be by regulating the position of location division 70 on guide rod 50 to carry out the elastic force of regulating spring 90.Nut is connected decrement that can regulating spring 90 with guide rod 50 by screw thread, and then can pass through control spring elastic force, makes hinge 100 under different condition, meet the demand of product to spring 90 elastic force.
As shown in Figure 2, nut is in the used time of doing that is subject to spring 90 elastic force, easily move along the axial direction of guide rod 50, for preventing that nut from moving along the axial direction of guide rod 50 after the effect that is subject to spring 90 elastic force, according to one embodiment of present invention, the below of nut is provided with the packing ring 71 being threaded with guide rod 50.Be understandable that, packing ring 71 can be to be also threaded with guide rod 50, so that packing ring 71 is fixed on guide rod 50, prevents that nut and guide rod 50 from moving because of the elastic force that is subject to spring 90, meanwhile, also can prevent the result of use because of the irregular variable effect hinge 100 of elastic force.Particularly, packing ring 71 can be anti-skid washer.
As shown in Figure 3, according to one embodiment of present invention, spring protecting sleeve 80 comprises: pipe portion 81 and annular turn-up portion 82.Particularly, pipe portion 81 is set on guide rod 50, and annular turn-up portion 82 is located at the upper end of pipe portion 81, and the lower end of the upper end of annular turn-up portion 82 and packing ring 71 offsets.In other words, annular turn-up portion 82 extends and protrudes from the periphery wall of pipe portion 81 along the circumferential direction of pipe portion 81, annular turn-up portion 82 is between the lower end of packing ring 71 and the upper end of spring 90, and pipe portion 81 is outer to be enclosed within on guide rod 50, and spring 90 is outer to be enclosed within pipe portion 81.
In addition, be understandable that, spring protecting sleeve 80 can be POM spring protecting sleeve 80, the spring protecting sleeve 80 of POM material has more antiwear characteristic, thus, can farthest avoid spring 90 to bend along departing from rail axis direction, avoid spring 90 and guide rod 50 frictions to produce noise.
As shown in Figure 3, according to one embodiment of present invention, the lower end of guide rod 50 is arranged with the distance piece 51 between spring 90 lower ends and supporting seat 60.Alternatively, distance piece 51 can be rubber spacers 51.Thus, can further avoid directly contacting with supporting seat 60 noise producing because of spring 90.
In specific embodiments more of the present invention, as shown in Figure 2 and Figure 3, " C " shape connecting portion 52, the second pivotal axis 40 that the upper end of guide rod 50 has opening are located in " C " shape connecting portion 52.Thus, be convenient to guide rod 50 to be assembled on the second pivotal axis 40.For the axial direction of upper end edge the second pivotal axis 40 of preventing guide rod 50 moves, the second pivotal axis 40 is provided with the axle sleeve 41 that is positioned at " C " shape connecting portion 52 both sides, to limit the position of " C " shape connecting portion 52 on the second pivotal axis 40.
Be understandable that, the axle sleeve 41 of " C " shape connecting portion 52 both sides part that can be formed in one, on position axle sleeve 41 middle parts that are connected with " C " shape connecting portion 52, have along axle sleeve 41 circumferentially extend, towards axle sleeve 41 axis directions recessed with the suitable cell body 42 of " C " shape connecting portion 52.Thus, " C " shape connecting portion 52 can relatively rotate with axle sleeve 41.
It should be noted that, the suitable axle sleeve 41 of sheathed and " C " shape connecting portion 52 guide rod 50 on the second pivotal axis 40, makes contacting between guide rod 50 and the second pivotal axis 40 become face from a contact and contacts, thereby has increased the reliability of hinge 100.Cell body 42 structures in the middle of axle sleeve 41 can effectively be controlled the relative motion between guide rod 50 and the second pivotal axis 40, and then reduce noise.
According to the refrigerator of the embodiment of the present invention (scheming not shown), comprise above-mentioned hinge 100.
According to the refrigerator of the embodiment of the present invention, by spring protecting sleeve 80 being set between guide rod 50 and spring 90, can effectively prevent that spring 90 is towards the direction bending that departs from guide rod 50 center lines, avoid directly contacting and producing friction noise with guide rod 50 because of spring 90, thereby promote the performance of refrigerator, improved user's satisfaction.
