Description

Children trolley

The utility model relates to a kind of children trolley, particularly a kind of multipurpose children trolley.

In the prior art, children trolley, especially the multipurpose children trolley is by three angle adjustables, and it is for sleeping in to allow children sit.But because being length, fixes by connecting rod, so on horizontal position, be subjected to the restriction of its structure, length can only reach about 90 centimetres, and about 35 centimetres of width only are suitable for provisional children sleeping, can not use for a long time indoor, treat that the baby grows up after, just often be forced to abandon (see figure 1).Therefore, managing is not influencing under the normal behaviour in service, increases the function of children trolley, especially increases the size of horizontal position, and the sleep needs that adapt to big baby are the problems that urgently will solve.

The purpose of this utility model is by changing the connected mode or the structure of connecting rod, to make do not increasing under the situation of using size at ordinary times that increase the size of horizontal position, adaptation is baby's sleep needs greatly.

For achieving the above object, the utility model comprises one group of master's vertical connecting rod, one group of secondary vertical connecting rod that be arranged in parallel with above-mentioned main vertical connecting rod, one group with above-mentioned main vertical connecting rod and the hinged preceding diagonal control arm of secondary vertical connecting rod, a push rod that connects with the vehicle frame activity, the main vertical connecting rod of main vertical connecting rod and back before above-mentioned main vertical connecting rod comprises, the cross section of the main vertical connecting rod in back is the rectangle of hollow, the outline of preceding main vertical connecting rod can closely be inserted in the hollow space of the main vertical connecting rod in back, the secondary vertical connecting rod of secondary vertical connecting rod and back before above-mentioned secondary vertical connecting rod comprises, be provided with a chute in the rear end of preceding secondary vertical connecting rod, the leading section of the secondary vertical connecting rod in back is provided with a feather key, feather key can slide in above-mentioned chute, and limited its movement locus by chute, the whole transverse links that constitute vehicle frame all have the segmentation of telescopic mechanism and connect, wherein the two ends of push rod, the two ends of displacement pull bar, the two ends of preceding bib tranverse connecting rod, the two ends of preceding telescopic bar are the screw rod over-surplus fit structure.

The utlity model has length, the width that can change unitized frame, rational in infrastructure, change variously, especially can satisfy big baby's sleep needs, and when idle, not take too much space.

Of the present utility model a kind of behaviour in service schematic diagram of Fig. 7.

Now in conjunction with the accompanying drawings, further describe a kind of most preferred embodiment of the present utility model.

As can be seen from Fig. 1, this class children trolley of the prior art is made of by relation hinged, fixed or movable connection many groups rod member, the utility model improves on this basis and forms, so the no longer narration in this manual of identical or close with it parts should not sayed and instructed.

As can be seen from Fig. 2, children trolley of the present utility model have be divided into before and after two-part main vertical connecting rod (2,3), wherein before main vertical connecting rod 3 be enclosed within the back main vertical connecting rod in, its relation can be clearly visible from Fig. 4 and Fig. 5.Promptly after the indentation fully of main vertical connecting rod 3 in the main vertical connecting rod 2, and the front end of preceding vertical connecting rod 3 is with preceding diagonal control arm 9 links, the rear end puts in main vertical connecting rod 2 afterwards, and is provided with a stop part (not shown) and prevents that it from deviating from.

From Fig. 2, be also shown in, be provided be divided into before and after two-part secondary vertical connecting rod (4,5), wherein before secondary vertical connecting rod 5 be provided with a chute in its back-end.The secondary vertical connecting rod 4 in back is provided with a feather key that can slide at front end in above-mentioned chute, see Fig. 6 for details.

Fig. 3 be from Fig. 2 front upper place to the partial schematic diagram of seeing in the past, wherein the middle part of lower link 7 connects with a hollow pipe.And be provided with a pin locating hole.Two ends at push rod 1 connect with the mode that two side connecting rods are the screw rod interference fit.The connection at the B among Fig. 3, C, D, E place is all identical with the A place, and the connection of other each cross bars, but can be enclosed within the sheath with the H place with the annexation at the structure at H place, J place.Also can adopt other suitable movable connecting modes.

Fig. 7 has represented a kind of behaviour in service of the utility model most preferred embodiment and has been provided with a top mosquito net 10.

Number in the figure 6 is front bib tranverse connecting rod, label 10 tranverse connecting rod that stretches before being, and label 12 is the displacement pull bar.
