Abstract

The utility model relates to a skeleton structure of baby carriage, in particularly referring that a seat frame of the skeleton pivots at the front and back wheel brackets. The seat frame comprises a front seat rod and a back seat rod pivoted with an actuator, which can slide, mutually pivoted. When folding the skeleton, the actuator can be driven to slide by a coupling element to make the back seat rod pressed by means of the actuator, making the seat frame form a folding; then the front wheel bracket and the back wheel bracket are driven to close to the middle or unfold, finally the utility model obtains a smooth folding effect.

Description

The skeleton structure of perambulator

Technical field

The utility model relates to a kind of skeleton structure of perambulator.

Background technology

General carrying baby's perambulator, usually the rod member with pivot joint each other presents a connecting rod form, by releasing mechanism control one joint set that is arranged between rod member, and have one by the release of the latching device in the middle of the joint set and snap close and launch to carry baby's the expansion use location and the collapsed position of a collapsible storing, as U.S.PAT.No.5,772,235 and No. 175901 patent case of patent gazette, but because the cooresponding complexity of connecting rod assembly of this kind perambulator, not only the assembling on cooresponding difficulty and the also very numerous rope of formality, and because the rod member of its formation is quite a lot of, therefore cause the relative increase of skeleton weight of integral body, the user is comparatively heavy when moving, and the poor effect of interlock during folding, the also problem that causes skeleton to have some setbacks when folding easily.

Summary of the invention

Therefore, have the assembly complexity for solving above-mentioned known perambulator skeleton structure, with and the problem that has some setbacks in folding of skeleton, the utility model provides a kind of skeleton structure of perambulator, which comprises at least: a front-wheel support, it is connected in wheel before this perambulator; One rear wheel support, it is taken turns after being connected in this perambulator; One handle pipe; One mounting includes one and articulates seat bar and back seat bar before each other, and this mounting also is articulated in front-wheel support and rear wheel support respectively; It is characterized in that between described rear wheel support two ends, being provided with a fastening base; Between described handle pipe two ends, articulate a coupling assembling, this coupling assembling can be used as the handrail of this perambulator supported on both sides, and this coupling assembling other end and this front-wheel support and this rear wheel support articulate, and one of this handle pipe end system releasably with this fastening base snapping; And a moving part, its two ends system articulates respectively between this handle pipe and this rear wheel support; One actuator is slidably to be installed on described back seat bar, and this actuator also is connected with this moving part.And this actuator is when lying in the skeleton folding; driven slip by moving part, make it press this back seat bar, in order to do making mounting form folding by this actuator; and then drive this front-wheel support and rear wheel support and draw close or launch to the centre, make the utility model reach comparatively smooth and easy folding effect.

The utility model other purpose and the category that further is suitable for, can be by clear learning in following being described in detail.But, these detailed narrations and the embodiment that is mentioned only use for explanation, because various change of being made in spirit of the present utility model and category and correction are for the professional person in the industry, can from these detailed descriptions and graphic clear learning, but the usefulness that these describe in detail and accompanying drawing only explains, and should not limit to the utility model.

The specific embodiment

The technology contents that the utility model is disclosed, please cooperate with reference to figure 1 with shown in Fig. 2, skeleton 90 structures of the perambulator of the utility model mainly are to articulate institute each other by members such as a front-wheel support 1, a rear wheel support 2, moving part 3, fastening base 4, a handle pipe 5, mounting 6, coupling assembling 7 and actuators 8 to constitute, it has a deployed condition, as shown in Figure 1, and a folding state, as shown in Figure 4.

Wherein front-wheel support 1, and its lower end system takes turns 10 before connecting this perambulator, and its upper end system articulates with coupling assembling 7.Rear wheel support 2, its lower end system takes turns 20 after connecting this perambulator, and the upper end then articulates with coupling assembling 7, is to be provided with a fastening base 4 between its two ends in addition, keeps the deployed condition of skeleton 90 with the clip of handle pipe 5 by this fastening base 4.

Handle pipe 5 articulates the handrail of a coupling assembling 7 as this perambulator in order to promote this perambulator between the two ends, this coupling assembling 7 other ends system articulates with this front-wheel support 1 and this rear wheel support 2 respectively; End is that device has a holding piece 51 under this handle pipe 5 in addition, by this holding piece 51 releasable modes and this fastening base snapping, and then to produce or to remove an interlocking state that betides between this rear wheel support 2, this coupling assembling 7 and this handle pipe 5: in the middle of present embodiment, these holding piece 51 main systems utilize a releasing mechanism 52 to control this holding piece 51 moving, and this releasing mechanism 52 can be as the device of No. 6443479 patent case of No. the 515423rd, the Taiwan patent announcement or the U.S..

Moving part 3, one end system is articulated in handle pipe 5 lower ends, and the other end then is articulated among the rear wheel support 2 on the fragment position.Mounting 6, include one and articulate seat bar 61 and back seat bar 62 before each other, wherein this front stall bar 61 is to be articulated in front-wheel support 1, and this back seat bar 62 then is articulated in rear wheel support 62, by the expansion and the folding of this mounting 6, and then drive the expansion and the folding of this front-wheel support 1 and rear wheel support 2.Actuator 8 is slidably to be installed on seat bar 62 after the mounting 6, and this actuator 8 also is connected with this moving part 3, and it is mobile to make it can drive actuator 8 by the rotation of this moving part 3.

By above-mentioned member, when skeleton 90 launched, main system was fixed by the holding piece 51 of the handle pipe 5 lower ends clip mutual with being fixed in fastening base 4 on the rear wheel support 2, can't rotate in order to do making each rod member form deadlock, and then provide that the carrying baby is virgin to be used; And when desiring the folding skeleton, then discharge this holding piece 51, and operation promotes handle pipe 5 forward, by the rotation of these handle pipe 5 drive moving parts 3, and because this actuator 8 is and moving part 3 articulates.Therefore, when moving part 3 rotates, can drive actuator 8 simultaneously and move, and then press back mounting 62 and fold with front stall bar 61 and be down " V " font, by folding of this mounting 6 front-wheel support 1 and rear wheel support 2 are drawn close in order to do making each other, and then reached the purpose person of folding perambulator skeleton.
