Abstract

The utility model relates to a multi-functional pram. The foldable prams which are in use now have small sizes and few functions as well as short practical period. Bamboo or wooden structure prams are unable to fold and inconvenient for altering direction in spite of having relatively great sizes. The pram body design of the utility model adopts a symmetrical folding structure, and the pram body is designed into a lever type vibration-proof structure with a tension spring, which is provided with a vibration-proof function and can alter direction discretionally. The pram can be used for sitting, standing and lying. The multi-functional pram is provided with a displacement tent which can adjust the shading area, a bidirectional movable desk with adjustable positions, distances and directions, and an electronic musical apparatus. The multi-functional folding vibration-proof pram having electric music can be always used in the process of the growth of the young children without the need of changing prams, having a long practical period, and the multi-functional folding vibration-proof pram having electric music is comfortable to use, flexible and convenient.

Description

Multi-functional folding vibration-proof pram having electric music

The utility model is about carriage for children, the invention of particularly shockproof folding multi-functional music perambulator.

Existing perambulator divides collapsible and not collapsible two classes: folding by bus with sit that the sleeping carriage volume is little, function is few, can not sit, stand, three usefulness that crouch and practical phase lack, and generally can only use the child about one one full year of life; The perambulator volume of bamboo-wood structure is bigger, though three usefulness of sitting, stand, crouch can not fold and turn to inconvenience, not shockproof, its tables and chairs all are the locate mode structure, use restricted.

The purpose of this utility model is to solve the problem of existing perambulator in using, and provides a kind of promptly collapsible, have seats, upright, function such as crouch again and be equipped with fix shockproofly take turns, the perambulator of shockproof cardan wheel, bi-directional movable tables and chairs, displacement sunshade and electronic music apparatus.

Technical solution of the present utility model is: car body is designed to the symmetrical fold structure, is that plane of symmetry two parts symmetrical connecting portion all adopts articulated structure with its vehicle body side middle vertical plane, and the also corresponding employing hinge of other connecting portion is hinged; Wheel design is the lever shockproof structure with extension spring, and wherein extension spring one end of trailing wheel is connected with the axis of orientation cover; On the backrest at seat there be than the chain supporting component design.

Accompanying drawing has been described an embodiment of the present utility model.
