When as perambulator, to guarantee safety that child is sitting on the seat board, as a preferred technical scheme for, According to Fig.7,2 top of shell is equipped with shield baby's railing 26 far from the side of the pull rod 3, and the shield baby railing 26 is set as U-shaped structure, the top left and right sides of the shell 2 are equipped with slideway, and the U-shaped structure both ends of shield baby's railing 26 are inserted into respectively In the slideway of 2 left and right sides of shell, it is right to the pull rod 3 that the activity direction of the slideway surpasses for the side of the pull rod 3 The activity setting back and forth of the side in face；

The U-shaped lower concave part center of shield baby's railing 26 and a side external surface of the shell 2 far from the pull rod 3 Equipped with shield baby with 27, the lower section of shield baby's railing 26 is symmetrically arranged with one group of pocket body 28, and the opening portion 19 of the pocket body 28 is distinguished Shield baby's railing 26 and the shield baby are connected with 27 lower section.The shield baby is with being set as flexible material, preferably nylon material.

In use, the support rod 5 is pulled open, the support rod 5 is made to form angle, and the fixed branch with the shell The position of strut 5；The upper cover and the guardrail are opened, while the flexible air-bag and the second air bag being inflated and being consolidated It is fixed, shield baby's railing is finally pulled open, child is placed on the seat board, two feet of child are respectively protruding into the pocket body 28 It is interior, thus luggage case can be converted to perambulator, and when progress article is taken, it can be by opening the storing door and to institute The intracorporal article of case is stated to be taken or stored.

When in use, for the position convenient for the fixation support rod, facilitating the support rod and described outer as perambulator Idler wheel below shell realizes the movement of whole boxcar together, is as a preferred technical scheme described according to Fig. 8 and Fig. 9 5 ball-joint of support rod is connected to mandril 30, the support in the outside of the shell 2, the close hinged end flexural pivot of the support rod 5 Bar 5 is equipped with the first groove 31 close to the side of the shell 2

The shell 2 is equipped with the first groove 31, and first groove 31 is described close to the hinged end of the support rod 5 First groove 31 cooperates for the mandril 30 insertion, and buckle 32 is symmetrically arranged on the shell 2, and the buckle 32 supplies the support Bar 5 is fixed close to one end of the idler wheel 6；

The mandril 30 is equipped with card slot 33 far from one end of the support rod 5, and the card slot 33 is set as ring structure, and sets In the outer circumferential of the mandril 30,

The side of first groove 31 is equipped with the second groove 34, is equipped with the first key 35, institute in second groove 34 It states the first key 35 and is set as L-type structure, described first key, 35 one end extends to the outside of second groove 34, and the other end passes through It wears and is inserted into first groove 31, the first spring is equipped between first key 35 and the inner wall of second groove 34 36。

The support rod 5 is connect with 2 ball-joint of shell, when as perambulator in use, by by it is described buckle 32 The support rod 5 of upper fixation is removed, and the buckle 32 is set as two half opposite arcuate structures of opening, and half arcuate structure is set as Plastic cement material, preferably ABS material.The mandril and the support rod 5 are set as ball-joint, and therefore, the mandril is lifted, and Stir first key 35, make 35 slide downward of the first key, first key 35 and second groove 34 it Between the first spring 36 compression, at this point, the mandril is put into first groove 31, unclamp again first key 35, First key 35 can be caught in the card slot 33, the mandril can be fixed, after the position of the mandril is fixed, The support rod is stationary state, and the purpose that boxcar is converted to perambulator can be realized.When as luggage case in use, First key 35 is pulled open downwards, compresses first spring 36, first key 35 is detached from the card slot at this time After 33, the mandril 30 is removed into first groove 31, the support rod can be converted to hinged state by stationary state, The support rod is pressed in the buckle 32 at this time, packing up for the support rod can be realized, and realizes perambulator and turns It is changed to the purpose of luggage case.

When hot weather, for convenient for providing a comfortable perambulator environment to child, as a preferred technical scheme For according to Figure 10 and Figure 11, the frame body 1 and the cross bar 8 are set as cavity, and the side of second air bag 17 is equipped with Third air bag 49, the third air bag 49 are equipped with branch sac line 50 far from the side of second air bag 17, and the branch sac line 50 is set Be it is multiple and be spaced setting, the branch sac line 50 is arranged vertically downward by the top of the third air bag 49, and the branch sac line 50 are equipped with gap with the bottom of the third air bag 49,

The top of the third air bag is equipped with liquid injection port 48, and the upper cover 10 is equipped with close to the side of second air bag 17 50 outside of branch sac line is arranged in bracket 51, the bracket one by one respectively.

In use, second air bag 17 is inflated, second air bag is i.e. inflatable to be propped up, second air bag After 17 expansions are propped up, the branch sac line 50 of the third air bag 49 is extruded after second air bag is propped up and close to the branch Frame 51, the bracket 51 is set as L-type structure, and is fixedly connected with setting with the bottom of the upper cover.By in the third air bag The liquid injection port 48 of 49 tops injects water can make child lean against the third after the third air bag 49 is filled and strutted by water On air bag 49.Since the third air bag 49 is equipped with multiple branch sac lines 50, each branch sac line divides the third air bag 49 It, can be through squeezing between each utricule after lattice are the utricule of multiple bottoms connection, therefore child leans against on the third air bag And the intracorporal liquid of respective capsule is mutually balanced, to avoid utricule because of the case where squeezing explosion.Simultaneously as each branch sac line 50 intervals are located on the third air bag, therefore the height of its outer surface is above the branch sac line after each utricule water filling, The bracket 51, which is located on the outside of each branch sac line, will not press against the back for being pressed onto child.

The pull rod 3 can also be set as foldable structure, and folding direction is set as folding to the lateral surface of the shell 2.Therefore It ensures that boxcar is convenient for storing when not in use convenient for the multifunctional comprehensive, the pull rod 3 is avoided to generate damage of colliding with Situation.

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes among the protection scope created still in the utility model.
