Shown in composition graphs 1 to Fig. 5, to sum up, when in the present invention, Bidirectional door opening apparatus 100 uses, user can direct control toggle mechanism 3, namely when needing the door body 82 of refrigerator 800 to be set to open to the left, directly driver plate 31 can be turned clockwise, driver plate 31 just can be with moving cam 321 to turn clockwise, thus promotion connecting rod 2 is moved to the left, now, blocking mechanism 20 on the right side of connecting rod 2 leaves opening portion 10 gradually, and then the restriction departed from this side fixed leg 813, and then refrigerator 800 bodies 82 can be opened from this side, be fixed leg 813 shown in composition graphs 3 to depart from from this side with the state making a body 82 open.
In above process, the blocking mechanism 20 on the left of connecting rod 2 stretches in opening portion 10 more, to limit the fixed leg 813 of this side, in addition, in toggle mechanism 3 two extension springs 331 and push rod 332 active force under, this kind of opening door body state after Bidirectional door opening apparatus 100 of the present invention can effectively keep user to regulate, be specially: drive two push rods 332 carry out clockwise simultaneously and move along connecting rod 2 length direction when cam 321 turns clockwise, now, the first fixed axis 3321 on push rod 332 then moves counterclockwise simultaneously and moves towards cam 321 direction in guide channel 22, the tensile elongation of two extension springs 331 is shortened, and under the pulling force effect of two extension springs 331, make this kind of state of cam 321 and push rod 332 be preserved, if cam 321 and push rod 332 need to reset, need the pulling force overcoming extension spring 331.
When needing the door body 82 of refrigerator 800 to be set to open to the right, as long as according to occupation mode reverse operating above.It can thus be appreciated that in the present invention, Bidirectional door opening apparatus 100 directly can realize the adjustment in the opening door body direction of refrigerator 800 bodies 82 by adjustment toggle mechanism 3, simple and convenient, do not need completely professional visit gymnastics do, time saving and energy saving, and its structure is simple, cost is lower.
Please refer to another embodiment that Figure 6 shows that Bidirectional door opening apparatus of the present invention, the difference of the Bidirectional door opening apparatus in itself and the first embodiment is toggle mechanism.In the present embodiment, the interlinked mechanism 42 in described toggle mechanism is comprise the described mating groove 21 that is formed on described connecting rod 2 and be connected with driver plate 41 and be arranged at the cam 421 in mating groove 21; Described restriction mechanism 43 is for being connected to the elastomer between cam 421 and housing 41.This elastomer 43 can keep the state of cam 42, and then limits the location status of connecting rod 2.The diapire 111 of described shell body 11 is equipped with the first locating shaft 116 in order to fixing elastomer 43 one end.
Described cam 421 is arranged in the mating groove 21 of connecting rod 2, and matches with the inwall of mating groove 21, can support the inwall of mating groove 21 and drivening rod 2 moves left and right when cam 421 is rotated.Described driver plate 41 is provided with the connecting portion 412 passed towards the operating portion 411 outside housing 1 and the perforation on shell body 11 115.Described cam 421 is provided with and the fixing hole 421 that connecting portion 412 fixes and the second locating shaft 422 of extending along diapire 111 direction of vertical shell body 11.The other end of described elastomer 43 is fixed on described second locating shaft 422.Described cam 421 is provided with protuberance 423 diametrically and recess 424, and described second locating shaft 422 is arranged on described protuberance 423.
Shown in composition graphs 1, described elastomer 43 is torsion spring in the present embodiment; In an initial condition, the protuberance 423 of described cam 42 is arranged towards rear wall 114 direction, and now described cam 42 and the first locating shaft 116 are located along the same line along housing 1 width.
In the present embodiment, the described mating groove 21 on connecting rod 2 is arranged at the centre position of described connecting rod 2, and really, described mating groove 21 also can be arranged on other positions between two groups of blocking mechanisms 20.
In this embodiment, when in the present invention, Bidirectional door opening apparatus uses, user can direct control toggle mechanism, namely when needing the door body 82 of refrigerator 800 to be set to open to the right, directly driver plate 41 can be turned clockwise, driver plate 41 just can be with moving cam 421 to turn clockwise, thus promotion connecting rod 2 moves right, now, one sideway swivel of cam 42 is to supporting the side inwall of mating groove 21 near antetheca 113, torsion spring 43 supports the second locating shaft 422 and keeps this kind of cam 42 postrotational location status, blocking mechanism 20 on the left of connecting rod 2 leaves opening portion 10 gradually, and then the restriction departed from this side fixed leg 813, and then refrigerator 800 bodies 82 can be opened from this side.
In above process, the blocking mechanism 20 on the right side of connecting rod 2 stretches in opening portion 10 more, to limit the fixed leg 813 of this side; In addition, in toggle mechanism torsion spring 43 twisting force under, this kind of opening door body state after Bidirectional door opening apparatus 100 of the present invention can effectively keep user to regulate.
When needing the door body 82 of refrigerator 800 to be set to open to the left, as long as according to occupation mode reverse operating above.It can thus be appreciated that in the present invention, Bidirectional door opening apparatus 100 directly can realize the adjustment in the opening door body direction of refrigerator 800 bodies 82 by adjustment toggle mechanism, simple and convenient, do not need completely professional visit gymnastics do, time saving and energy saving, and its structure is simple, cost is lower.
In addition, shown in composition graphs 6 and Fig. 7, shown in Fig. 7, described in another embodiment, elastomer 43 also can be extension spring or stage clip, in this kind of situation when original state, the protuberance 423 of described cam 42 is arranged towards antetheca 113 direction, and same described cam 42 and the first locating shaft 116 are located along the same line along housing 1 width.In this embodiment, just contrary when the direction of rotation of described cam 42 is torsion spring with above-mentioned elastomer 43, and after cam 42 rotates, the side of cam 42 and mating groove 21 offset near the side inwall of rear wall 114, be in the second locating shaft 422 that the extension spring of extended state or stage clip pull cam 42, thus keep the postrotational location status of cam 42.
In sum, Bidirectional door opening apparatus 100 of the present invention is directly at the extended blocking mechanism 20 in connecting rod 2 two ends, and by reversing driver plate 31, 41 and promote connecting rod 2 and move left and right, thus make the opening portion 10 on the blocking mechanism 20 closure or openness housing 1 at connecting rod 2 two ends, make user can direct control driver plate 31, 41 foldings that can realize the blocking mechanism 20 of connecting rod 2 both sides switch, and then the switching of a body 82 opening direction can be carried out to the refrigerator 800 being provided with this Bidirectional door opening apparatus 100, simple and convenient, do not need completely professional visit gymnastics do, time saving and energy saving, and its structure is simple, cost is lower.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
