Abstract

A pushchair is composed of an outer U-shaped tubular framework part, an inner U-shaped tubular framework part, wheels and an axle. The wheels are installed on the axle through free ends of support arms of the outer U-shaped tubular framework part and the inner U-shaped tubular framework part, a pivot pin penetrates the support arms of the outer U-shaped tubular framework part and the inner U-shaped framework part and a support, and the support arms are adjacent to the support. The support comprises a base plate, two first notch plates and two second notch plates, the two first notch plates and the two second notch plates are arranged on four lateral edges of the base plate in a two-two corresponding mode respectively, and the extending directions of the first notch plates and the second notch plates are opposite. The support can either comprises the base plate and the first notch plates, the first notch plates are arranged at two ends of the base plate, one side of the base plate extends to form an inclined part, an extending part is formed on the inclined part, and the extending direction of the extending part is opposite to the direction of the first notch plates. The pushchair is simple in structure, can move relatively when being folded, easy to assemble and convenient to carry or store and has high stability in terms of safety.

Description

Pushchair

Technical field

This utility model has related to a kind of pushchair, particularly a kind of pushchair with tubulose frame member.

Background technology

When people carry small children away in the past, mainly be to carry child or child is embraced at oneself on hand.Along with the progress of science and technology, place problem in order to solve for child.People have invented go-cart.This invention has alleviated burden on one's body, can push away child's stroll of going into the street, and plays.But go-cart is owing to its structure is special, it is bigger to need four wheels to support the general relatively chair of the bulking value of car, and car is put no the time at home, it is bigger to take up room, also caused some inconvenience, because not folding, not light when people carry yet, comparatively loaded down with trivial details on assembling process, seem heavy.As indicated above, traditional go-cart has the some shortcomings part, so existing utility model can provide a kind of pushchair with tubulose frame member.It is the pushchair that the advantage of a kind of frame member with go-cart and folded seat combines.

The utility model content

The purpose of this utility model provides a kind of being easy to carry, the pushchair that folds easily when storage.Be fit to do the toy pushchair that child adorns cloth doll, can also be used for pushing away child.

The technical solution of the utility model: a kind of pushchair, formed by outside U-shaped tubular frame parts, inner U-shaped tubular frame parts, wheel and axletree, externally on the free end of U-shaped tubular frame parts, inner U-shaped tubular frame parts support arm wheel is installed on the axletree, pivot pin passes on the support arm and support of adjacent outside U-shaped tubular frame parts and inner U-shaped tubular frame parts.Support comprises base plate, frid one and frid two; Frid one respectively has two with frid two, and lays respectively at relatively in twos on four sides of base plate, and frid one is opposite with the direction that frid two extends.The outside U-shaped tubular frame parts of pushchair and the arm length of inner U-shaped tubular frame parts differ.The inside face of two frids two in opposite directions has curved surface.Support can comprise base plate and frid one, and frid one is positioned at the two ends of base plate, and a side of base plate is extended a sloping portion, and an extension component is arranged on the sloping portion, and the bearing of trend of extension component is opposite with frid one.

Advantage of the present utility model: simple in structure, only have two parts, it can relatively move when folding pushchair.The chair assembling is simple, the safety factor height.Be easy to carry or store.

Description of drawings

To further describe existing utility model by concrete legend below:

That Fig. 1 represents is the integral structure figure of the utility model pushchair;

Fig. 2 represents is the detail view that amplify the pivot junction of two framing members of the utility model pushchair;

Fig. 3 is the detail view of another kind of type of attachment corresponding to Fig. 2.

Indicate among the figure: 1, outside U-shaped tubular frame parts, 2, inner U-shaped tubular frame parts, 3, wheel, 4, axletree, 5, pivot pin, 8, support, 9, frid one, 10, base plate, 11, frid two, 12, curved surface, 211, side members, 212, sloping portion.

The specific embodiment

In conjunction with relevant drawings, as follows to being described in detail of existing utility model:

As shown in Figure 1, pushchair comprises that two are roughly outside U-shaped tubular frame parts 1 and inner U-shaped tubular frame parts 2, on the free end of these parts support arms wheel 3 is being installed on the axletree 4, this axletree also can play the effect of holding outside U-shaped tubular frame parts 1 and inner U-shaped tubular frame parts 2 by pipe.Wherein the support arm of outside U-shaped tubular frame parts 1 is longer than inner U-shaped tubular frame parts 2 relatively, as handle chair is promoted.Inner U-shaped tubular frame parts 2 are narrower than outside U-shaped tubular frame parts 1, and its support arm has curved U-shaped in the plane.Outside U-shaped tubular frame parts 1 and inner U-shaped tubular frame parts 2 all are pivotally connected to by pivot pin 5.Wherein pivot pin 5 passes the adjacent support arm of U-shaped framework.Each pivot pin 5 at one end exposes head, then expands to prevent from dropping at its other end.Being positioned at the support 8 that connects arm room is relatively rotating for the restriction support arm.

As shown in Figure 2, support 8 has two frids 1 that extend from a side of base plate 10.These two frids 1 are being encircled a support arm, and fixed support 8 is in this.Two relative frids 2 11 are from the opposite side extension of base plate 10.Two relative frid 11 such layouts can support two support arms mutually a predetermined angle.Outside U-shaped tubular frame parts 1 and inner U-shaped tubular frame parts 2 weight, and any weight that loads to downwards on the pushchair all may force 11 contacts of the member support arm frid relative with two, to prevent collapsing of chair.When pushchair is folding, outside U-shaped tubular frame parts 1 and inner U-shaped tubular frame parts 2 are relative to each other rotation simply, so in general support arm all is parallel.Point to inner curved surface 12 and two relative frids 2 11, prevent that support arm from exceeding the folding position rotation.With reference to Fig. 3, the support 8 of connection has two frids 1 that extend to base plate 10 from a side, just as in an identical manner example shown in figure 2.Extend a sloping portion 212 from a side of base plate 10, an extension component 211 is arranged on the sloping portion 212, the bearing of trend of extension component 211 is opposite with frid 1.The support arm of outside U-shaped tubular frame parts 1 leans against in the side members 211.
