The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated.
Embodiment one: referring to Fig. 1-3; The rocking-type bassinet of present embodiment double-eccentric shaft interlock; Comprise under-carriage 1, hind axle 2, two trailing wheel 3-1,3-2, front-wheel 4, supporting body 5, handle 6, pre-eccentric axle 7, back eccentric shaft 8; Hind axle 2 cooperates with the posterior rotation of under-carriage 1, an end of hind axle 2 and trailing wheel 3-1 heavy keying fit, the other end and trailing wheel 3-2 normal-running fit.Two front-wheels 4 are cardan wheel, are installed on the front portion of under-carriage 1.Handle 6 is fixedly installed in the rear portion of under-carriage 1.Under-carriage 1 front and rear part is normal-running fit pre-eccentric axle 7, back eccentric shaft 8 respectively, and the two ends eccentric part of pre-eccentric axle 7 is crank throw 7-1,7-2, and the two ends eccentric part of back eccentric shaft 8 is crank throw 8-1,8-2.The stage casing of two eccentric shafts is respectively main shaft section 7-3,8-3.The specification of two eccentric shafts is identical, and promptly the off-centre of both end crank throws (apart from the stage casing) size is equal, eccentric direction is consistent, so that both rotations in the same way synchronously.
Assembling one driving gear 9 on the hind axle 2, the stage casing 8-3 of back eccentric shaft 8 assembles a driven gear 10, and driving gear 9 rotates thereby hind axle 2 just can drive back eccentric shaft 8 through intermediate gear 11 and driven gear 10 engagements.In tooth rest 13, hind axle 2 passes tooth rest 13 through axle 14 normal-running fiies for intermediate gear 11, and normal-running fit between the two.
Wave before the both sides, front and back of supporting body bracing frame 14 bottoms respectively offer hole 14-1, after wave hole 14-2.Wave two end crank 7-1, the 7-2 difference normal-running fit of hole 14-1 and pre-eccentric axle 7 before the both sides, wave two end crank 8-1, the 8-2 difference normal-running fit of hole 14-2 and back eccentric shaft 8 behind the both sides.The stage casing 8-3 of back eccentric shaft 8 also assembles a drive sprocket 15, and the stage casing 7-3 of pre-eccentric axle 7 also assembles a driven sprocket 16, and drive sprocket 15 links to each other with driven sprocket 16 through chain 17 and links, and rotates thereby back eccentric shaft 8 just can drive pre-eccentric axle 7.
Supporting body 5 comprises bracing frame 14 and landing portion 18, and both sides, supporting body bracing frame 14 top form track, and the sliding type landing portion 18 that is used to assemble fore-and-aft direction adopts locator card or locating dowel pin to come relative positioning between the two.Landing portion 18 has inner landing space, and its rear portion is through normal-running fit one backrest 19, and this backrest 19 can spin upside down, and under the normality, backrest 19 is in the shape that recedes slightly (referring to Fig. 2).Landing portion 18 is spurred forward, and the backrest 19 that gives a hard push backwards again makes it turn to horizontality, and landing portion 18 just is in deployed condition, and it can lie at (referring to Fig. 3) in it for the infant.
Certainly, supporting body also can adopt following structure: captive joint between bracing frame and landing portion, captive joint between landing portion and backrest.
Embodiment two: as shown in Figure 4, the difference of present embodiment and embodiment one is: two ends 8-1, the 8-2 of back eccentric shaft 8 are the main shaft section, and stage casing 8-3 is an eccentric segment; The two ends 7-1 of pre-eccentric axle 7,7-2 are the main shaft section, and stage casing 7-3 is an eccentric segment.Driven gear 10 is on the end 8-1 of back eccentric shaft 8, driving gear 9 direct and driven gear 10 engagements on the hind axle 2.Drive sprocket 15 is on the other end 8-2 of back eccentric shaft 8, corresponding ground, and driven sprocket 16 is on the end 7-2 of pre-eccentric axle 7 homonymies.Wave hole 14-1 normal-running fit before the stage casing 7-3 of pre-eccentric axle 7 and the supporting body bracing frame 14, wave hole 14-2 normal-running fit behind the stage casing 8-3 of back eccentric shaft 8 and the supporting body bracing frame 14.
But other content reference implementation example one of present embodiment.
Embodiment three: as shown in Figure 5; The difference of present embodiment and embodiment one is: hind axle 2 and back eccentric shaft 7 no interaction relations; The main shaft section 8-3 of eccentric shaft 8 drives through motor 20 and rotates behind the present embodiment, and the output shaft of motor 20 is through gear 23 interlocks on the stage casing 8-3 of a drop-gear box 22 and back eccentric shaft 8.
But other content reference implementation example one of present embodiment.
Embodiment four: in the present embodiment, the eccentric part of front and back eccentric shaft does not adopt the structure of two end cranks, but adopts structure shown in Figure 6.Because the structure of front and back eccentric shaft is identical; Below after eccentric shaft be that example describes: the back eccentric shaft 8 two ends assemble an eccentric wheel 21 respectively; Be the axis of eccentric shaft 8 and non-being on the same straight line in axis of eccentric wheel 21; Thereby formed the eccentric part structure of the another kind of eccentric shaft of the present invention, promptly eccentric part adopts eccentric wheel structure.The outer ring of eccentric wheel 21 be in the supporting body bracing frame after wave within the 14-2 of hole.Back eccentric shaft 8 rotations can drive eccentric wheel 21 and rotatablely move as centering type, in this process, the outer ring of eccentric wheel 21 can contact the supporting body bracing frame after wave hole 14-2, thereby make supporting body bracing frame and supporting body do corresponding motion.
But other content reference implementation example one or three of present embodiment.
Certainly, in the present embodiment, eccentric wheel also can be arranged at the stage casing of eccentric shaft but not the end also can reach the corresponding techniques effect.
Embodiment five: in the present embodiment, assemble driving pulley on the hind axle, the main shaft section assembling driven pulley of back eccentric shaft passes through belt-driving between two belt pulleys.
Other content of present embodiment can reference implementation example one or two or four.
Embodiment six: in the present embodiment, assemble drive sprocket on the hind axle, the main shaft section of back eccentric shaft assembling driven sprocket, between two sprocket wheels through chain gear.
Other content of embodiment can reference implementation example one or two or four.
Embodiment seven: in the present embodiment, and the main shaft section of back eccentric shaft assembling driving pulley, the main shaft section assembling driven pulley of pre-eccentric axle, two belt pulleys pass through belt-driving.
Other content of present embodiment can reference implementation example one to six.
Embodiment eight, in the present embodiment, and the main shaft section of back eccentric shaft assembling driving gear, the main shaft section assembling driven gear of pre-eccentric axle, two gears are through the intermediate gear engagement.
Other content of present embodiment can reference implementation example one to six.
In addition; In same embodiment, the eccentric part of front and back eccentric shaft can be crank throw and eccentric combination, and promptly the eccentric part of pre-eccentric axle adopts the crank throw structure; Then the eccentric part of eccentric shaft adopts eccentric wheel structure; Otherwise perhaps, as long as the eccentric throw of front and back eccentric shaft equates and eccentric direction is consistent, eccentric shaft rotation in the same way synchronously before and after guaranteeing.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not as to qualification of the present invention, as long as within the scope of the invention, all will drop on protection scope of the present invention to variation, the modification of above embodiment.
