Detailed description of the invention
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by detailed description of the invention.
Embodiment mono-:
The present embodiment provides a kind of embedded-type refrigerator door hinge, as shown in Figure 1 to Figure 3, this embedded-type refrigerator door hinge comprises fixed hinge seat 1, hinges seat 2, long fork 3, the first short fork 4, the second short fork 5 and the 3rd short fork 6, and long fork 3 one end are articulated with on fixed hinge seat 1.It is hinged with long fork 3 that the first short fork 4 and the second short fork 5 are one end, and the other end and hinges seat 2 are hinged.One end of the 3rd short fork 6 and fixed hinge seat 1 are hinged, and the other end is articulated with on the second short fork 5.On fixed hinge seat 1, be provided with two installing holes 12.Form six bar mechanism by fixed hinge seat 1, hinges seat 2, long fork 3, the first short fork 4, the second short fork 5 and the 3rd short fork 6, realize the open and close of embedded type refrigerator door, adopt six bar mechanism effectively to compress volume and the installation dimension of door hinge.
Wherein, the pitch-row L1 of two hinge points of fixed hinge seat 1 is 22 ± 3mm, is preferably 22.7mm.On long fork 3 with the hinged hinge point of fixed hinge seat 1 and with the pitch-row L2 of the hinged hinge point of the second short fork 5 be 41 ± 3mm, be preferably 41.1mm, on long fork 3 with the hinged hinge point of the second short fork 5 and with the pitch-row L3 of the hinged hinge point of the first short fork 4 be 37 ± 3mm, be preferably 37.6mm.The pitch-row L4 of two hinge points of the first short fork 4 is 44 ± 3mm, is preferably 44.2mm.On the second short fork 5 with the hinged hinge point of long fork 3 and with the pitch-row L5 of the hinged hinge point of the 3rd short fork 6 be 20 ± 3mm, be preferably 20.7mm, on the second short fork 5 with the hinged hinge point of the 3rd short fork 6 and with the pitch-row L6 of the hinged hinge point of hinges seat 2 be 24 ± 3mm, be preferably 24.6mm.The pitch-row L7 of two hinge points of the 3rd short fork 6 is 38 ± 3mm, is preferably 38.4mm.The pitch-row L8 of 2 two hinge points of hinges seat is 34 ± 3mm, is preferably 34.6mm.The pitch-row L9 of two installing holes 12 of fixed hinge seat 1 is less than on long fork 3 hinge point hinged with fixed hinge seat 1 and the pitch-row L10 with the hinged hinge point of the first short fork 4.
For Convenient switch door, on this door hinge, be provided with switch gate servomechanism.This switch gate servomechanism comprises and is arranged on the elastic booster 8 on long fork 3 and is arranged on the pressing rocking arm 7 on the first short fork 4.Pressing rocking arm 7 has bulge-structure 71 near one end of elastic booster 8, and bulge-structure 71 1 sides are arcwall face, and a side is plane, and arcwall face and Plane intersects form projection.Pressing rocking arm 7 can also play the effect of the rigidity of strengthening the first short fork 4.As shown in Figure 4, elastic booster 8 comprises through fixing pin (not shown) and is fixed on spring support 81 on long fork 3, is arranged at the spring 82 in spring support 81 and is arranged at the spring base 83 of spring 82 ends.One end near spring base 83 on spring support 81 has one section of chute 811, is provided with pin hole 831 on the outer peripheral face of spring base 83, and pin 84 is in chute 811 penetrates described pin hole 831.Two sides adjacent with the side that chute 811 is set on spring support 81 has bar shaped notch 812, and one side is wherein provided with the erection column 813 for fixing pin is installed, and the stage casing of erection column 813 caves inward to avoid itself and spring 82 to interfere.Because the spring 82 of this elastic booster 8 is fixed, do not need mobile, therefore take up room little, avoid spring 82 to move the quality problems that may bring, reliable in structure is durable, spring 82 stable working state, the life-span is long, and spring assistor 8 has also improved the structural strength of long fork 3.
When at closing time, the bulge-structure 71 of pressing rocking arm 7 rotates with the first short fork 4, as shown in Figure 5, bulge-structure 71 is gradually near spring base 83, now refrigerator doors is in free rotary state, until the arcwall face of bulge-structure 71 and spring base 83 butts as shown in Figure 6, the elastic force that bulge-structure 71 overcomes spring 82 is rotated further, as shown in Figure 7, when spring base 83 is crossed after the peak of bulge-structure 71, spring 82 rebounds, thereby the rotation of bulge-structure 71 is formed to power-assisted, form the power-assisted of closing the door, until refrigerator doors is completely closed, as shown in Figure 8, the plane of bulge-structure 71 and spring base 83 are fitted, and there is certain bounce, form self-locking effect.In the time opening the door, contrary with the process of closing the door, bulge-structure 71 plane one thruster flexible spring seats 83, spring 82 is compressed, and when crossing after the peak of bulge-structure 71, spring 82 rebounds, thereby the rotation of bulge-structure 71 is formed to power-assisted, form the power-assisted of opening the door, when forwarding to after certain angle, refrigerator doors is again in free rotary state.
In order to prevent from hitting a phenomenon, as shown in Figure 9, on fixed hinge seat 1, can plug and be provided with spacer pin 9, when refrigerator be placed on full angle open can cause hit door local time, spacer pin 9 can be inserted to fixed hinge seat 1, as shown in figure 10, in the time that long fork 3 forwards spacing angle to, spacer pin 9 can stop being rotated further of long fork 3, effectively prevents from hitting a phenomenon, do not need when spacing spacer pin 9 to be extracted, easy to operate.Spacing angle is preferably 90 °.
On fixed hinge seat 1, be also provided with brace rod 11 near the position of its hinge point, effectively improved the rigidity of fixed hinge seat 1, avoid the distortion of the hinge point surrounding structure hinged with long fork 3.
Wherein, the size of fixed hinge seat, hinges seat, long fork, the first short fork, the second short fork and the 3rd short fork is not limited to above-mentioned size, can set according to the concrete model structure of refrigerator, can realize switch gate function; On fixed hinge seat, be not limited to two installing holes are set, multiple installing holes also can be set, set by real needs; Switch gate servomechanism is also not limited to said structure, other structures that can realize switch gate assist function all can, as spring etc. is set separately.
Embodiment bis-:
