Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of cranking arm among Fig. 1 and taking turns.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1: door opener is positioned at the interlayer of refrigerator doors, and it comprises gear mechanism and by two keepers of the reverse interlock of its driving, two keepers contact with the keyhole that is positioned at the refrigerator doors left and right side and link to each other with refrigerator shell 17 respectively and interlock.
Said gear mechanism can be by constituting with connecting rod 9 hinged left and right gear trains.In each gear train: be provided with mounting box 5, large and small gear 6,11, two gears engaged that are movably connected with it are housed in the mounting box.The eccentric part of gear wheel and hand lever 18 1 ends are connected, it is outer to refrigerator doors groove 19 places that the hand lever other end stretches out mounting box, be fixed with the concentric with it wheel of cranking arm on the pinion, slide and link to each other in the crank arm termination of edge and upper and lower push rod 10,13 of wheel, upper and lower push rod is a keeper, be in a straight line together, its another termination contacts with keyhole 2,16 respectively and interlocks, and it stretches out on the outer body of rod of mounting box and has been with the spring 15 of reset response and has been with sleeve pipe 3,14 respectively; The two ends of connecting rod 9 respectively with left and right gear train in crank arm the wheel lower right-hand corner hinged.
Above-mentioned refrigerator doors is divided into refrigerating-chamber door 22, refrigerating chamber door 20, the structure of the door opener in its interlayer is identical, just: contact the keyhole that interlocks with two keepers of refrigerating-chamber door, its keyhole 2 can link to each other with the top cover 1 of refrigerator shell 17, and its keyhole 16 can link to each other with the interior dividing plate of refrigerator shell 17 between refrigerating-chamber door, door of refrigerator; And contact the keyhole that interlocks with two keepers of refrigerating chamber door 20, and its keyhole 2 can be shared with the keyhole 16 of refrigerating-chamber door, and its keyhole 16 can link to each other with the base plate of refrigerator shell 17.Sequence number 21 is inner casings of refrigerating-chamber door 22.
Above-mentioned refrigerator doors groove (19) when it is positioned at the upper end of refrigerator doors or lower end, stretches out outside the mounting box to the refrigerator doors groove at hand lever 18 other ends and can be provided with sleeve pipe 23; When it was positioned at the left end of refrigerator doors or right-hand member, hand lever 18 other ends stretched out directly that mounting box is outer to get final product to the refrigerator doors groove.
Can be provided with the sleeve pipe 8 that is connected with it between the above-mentioned mounting box 5, the body of rod of connecting rod 9 passes from its activity.
Above-mentioned wheel and the pinion 11 of cranking arm, the two can be connected by rivet 7.Perhaps, the two can be processed by a global facility.
In the above-mentioned left gear group, its hand lever upper end can be connected with the left eccentric part of its gear wheel.In the described right gear group, its hand lever upper end can be connected with the right eccentric part of its gear wheel.
Above-mentioned sleeve pipe 8,14,23 all can be fixed with one with mounting box 5.The effect of these sleeve pipes and mounting box is: the one, and the location; The 2nd, prevent that the refrigerator insulation material from entering in the gear train, to guarantee gear mechanism and by two keeper operate as normal of the reverse interlock of its driving.
As shown in Figure 2: above-mentioned left and right gear train, the structure of its wheel of cranking arm is identical, and radian is all arranged.Wherein, left and right side's indent radian R1 is 90 °, and the indent radian R2 of upper and lower is 12.5 °, and upper right corner radian is that R3 is 120 °; The installation difference of its wheel of cranking arm, that is: during positive the installation if be decided to be the left side wheel 4 of cranking arm, then anti-the mistake can be decided to be the right side wheel 12 of cranking arm when face is installed.
The course of work of the present utility model is summarized as follows.
1. open the door from the right: when being in Fig. 1 state, can open refrigerating-chamber door from the right.
2. open the door from the left side:
When finger when the groove 19 on the left side upwards pushes hand lever 18, the action of left gear group: gear wheel 6 drives pinion 11, the wheel of cranking arm (cranking arm and take turns 4 in a left side) inhour is rotated, connecting rod 9 is promoted to the right, crank arm along the left side edge of wheel of the upper end of the lower end of upper ejector pin 10, lower push rod 13 slides into its left and right side's indent radian R1 place, so, the lower end of the upper end of upper ejector pin 10, lower push rod 13 breaks away from keyhole 2,16 respectively, and promptly left side keeper is in open state.
Simultaneously, when connecting rod 9 promotes to the right, the right gear group oppositely links, its action is: the pinion 11 and the wheel of cranking arm (cranking arm and take turns 12 in the right side) inhour is rotated, make crank arm along the left side edge of wheel of the upper end of lower end, the lower push rod 13 of upper ejector pin 10 slide into the indent radian R2 place of its upper and lower, so the lower end of the upper end of upper ejector pin 10, lower push rod 13 interlocks with keyhole 2,16 respectively, promptly the right keeper is in locking-in state.
So, can open refrigerating-chamber door from the left side.
If open the door from the right, finger should upwards push hand lever 18 from the groove 19 on the right again, and then the action of left and right gear train is opposite with above-mentioned process, causes keeper to be in Fig. 1 state, that is: left side keeper is in locking-in state, and the right keeper is in open state.So, can open refrigerating-chamber door from the right.
