The specific embodiment
The utility model also may be implemented in the equipment that confession infants such as comprising high chair or rocking chair rides, sits, crouches, and this service plate device comprises auxiliary accessories such as service plate, toy disks or preceding railing except that being applicable to Carriage for baby.
As shown in Figure 2, Carriage for baby 1 of the present utility model comprises a carrier unit 2 and a service plate device 3.And this carrier unit 2 comprise mutual pivot joint one before lower beam group 21, a back lower beam group 22, a back upper boom group 23 and about two handrails 24.As shown in Figure 7, the front end of each handrail 24 has the bigger ring portion 242 of external diameter less a neck 241, external diameter and vertically runs through neck 241 and a circle hole 243 of ring portion 242.The Carriage for baby 1 of different type of machines, its service plate device 3 can be assembled in preceding lower beam group 21, back lower beam group 22, back upper boom group 23 or handrail 24 respectively.Originally executing example explains with the situation that is assembled in handrail 24.
Shown in Fig. 3 to 5, this service plate device 3 comprises slide block 32, an operating unit 33, an elastic component 34 and the lid 35 that a service plate body 31, that roughly is banana-shaped roughly takes the shape of the letter U.
This service plate body 31 has a base plate 311 and circle sidewalls 312 of extending of this base plate 311 certainly downwards.This sidewall 312 is formed with two circular holes 315 in a U-shaped breach 314 and Lve Chao the place ahead respectively at the opposite end of service plate body 31.This base plate 311 is near each breach 314 place, downwards projection one first guide block 316, one second guide block 317 and one the 3rd guide block 318.
One the 3rd guide groove 325 that this slide block 32 comprises a projection 321 from the outside longitudinal extension of U-shaped closed end, defined at the upwardly extending circle flange 322 of U closed end, a U-shaped fin 323 that extends downwards in U-shaped slide block 32 open ends, one first guide groove 324 that this flange 322 is defined and this fin 323.
This operating unit 33 comprises a cylindrical head 331 and a tabular afterbody 332.This head 331 and afterbody 332 can be one-body molded or by two separation assembly be combined intos.This afterbody 332 is formed with and is positioned at the stage casing as an inclined-plane lug of male part 333 be positioned at free-ended one second guide groove 334.
The following describes the assembling of service plate device 3: earlier slide block 32 is placed below the base plate 311 of service plate body 31, make first guide groove, 324 ccontaining first guide blocks 316, and the 3rd guide groove 325 ccontaining the 3rd guide blocks 318.Secondly an elastic component 34 is inserted in the slide block 32 of hollow, an end of this elastic component 34 props up the closed end of U-shaped slide block 32, and the other end of elastic component 34 props up the 3rd guide block 318.Then operating unit 33 is placed below the slide block 32, and head 331 is placed in the hole 315, and second guide block 317 is placed in second guide groove 334, this moment male part 333 rough fins 323 that are contacted with, and afterbody 332 can prevent that elastic component 34 from dropping.With screw (figure does not show) lid 35 is locked in service plate body 31 at last, and slide block 32 and operating unit 33 are covered, the forebody of only surplus head 331 is exposed to outside the sidewall 312 of service plate body 31.The center-point that can comprise second guide block 317 and the 3rd guide block 318 as for the locking point of screw.
The operation of service plate device 3: shown in Fig. 4,5, when the head 331 of pressing operation unit 33, operating unit 33 direction along arrow A under the guiding of second guide block 317 is slided, male part 333 pushes against fins 323 simultaneously, slide block 32 direction along arrow B under the guiding of first and third guide block 316,318 is slided, and elasticity of compression member 34.Because the projection 321 of this moment direction of arrow B before moves,, make the neck 241 of handrail 24 be placed in U-shaped breach 314 so can be assembled in handrail 24 this moment with service plate body 31.Remove the hand of pressing operation unit 33 then,, slide block 32 is moved along the direction opposite with arrow B, insert in the round hole 243 of handrail 24 up to projection 321 by the elastic restoring force of elastic component 34.This moment service plate device 3 can not along projection 321 axially or radially break away from handrail 24, so service plate device 3 and handrail 24 combination firmly.At the same time, operating unit 33 is subjected to the interlock of fin 323, also along the direction slip involution opposite with arrow A, as shown in Figure 4
As shown in Figure 5, when the infant that desires to pick and place in the Carriage for baby 1, the head 331 of pressing operation unit 33 makes the projection 321 of slide block 32 break away from the round hole 243 of handrails 24 once again.Then service plate device 3 integral body are upwards started, this end of service plate device 3 and handrail 24 are broken away from fully.If this operation is all carried out at the two ends of service plate device 3, then service plate device 3 integral body can be separated from handrail 24.If only carry out this operation at an end of service plate device 3, then the sidewall 312 of the other end is because be subjected to stopping of ring portion 242, therefore this other end of service plate device 3 can not be along the axial disengaging handrail 24 of projection 321, can only work as pivot with the neck 241 of the handrail 24 of this other end, allow service plate device 3 to turn over turnback, as shown in Figure 7, about making two handrails 24 between no any assembly constitute obstacle, conveniently to pick and place the infant.
Effect of the present utility model is: insert in the round hole 243 of handrail 24 by projection 321, and service plate device 3 is firmly combined with handrail 24.When projection 321 breaks away from circle hole 243, can't produce wearing and tearing, so even if repeated disassembled and assembled can not combine built on the sand with handrail 24 because of parts depreciation makes service plate device 3 yet, causing the infant has the danger on the ground of dropping, and therefore service plate device 3 of the present utility model is safe.
The utility model also can have other embodiment: first and third above-mentioned guide block 316,318 can be merged into a guide block with suitable length, as long as can keep the smooth and easy and direction that slide block 32 slides.Similarly, first and third guide groove 324,325 also can be merged into a guide groove, to cooperate with the guide block of this suitable length.
Though the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, under the situation that does not break away from the utility model spirit, also can make the variation or the replacement of various equivalences, therefore, as long as in connotation scope of the present utility model in the scope to the variation of the foregoing description, claims that modification all will drop on the application.
