Abstract

The utility model relates to a folding pram, comprising handle rods, a pair of front wheel rods, a pair of rear wheel rods, a pair of side rods, two bottom rods, two back rods, a pair of link pieces, two front composite wheels, two rear composite wheels, two hinge pieces, a seat liner cloth and a plurality of clamp tenons. The folding pram is characterized in that the components are all made of ABS or PP rubber-resin alloy, wherein, each handle rod, each front wheel rod and each rear wheel are all integrally molded with star-shaped or L-shaped hinging connection pieces. The utility model can be conveniently and rapidly assembled as a folding pram. Thus, the cost can be reduced, and the production efficiency can be raised. A user can also accomplish the assembling work by own hands.

Description

Folding pram

The utility model relates to a kind of perambulator, particularly a kind of Pushchair.Cooperates some rivets (4) riveted joint and form by a pair of handlebar stem (11) (12), a pair of front wheel bar (13) (14), pair of rear wheels bar (15) (16), an offside pole (17) (18), two bottom bars (19) (20), two back of the body bars (21) (22), a pair of double-action plate (23) (24), two preceding combined wheels (25) (26), two back combined wheels (27) (28), some Qian shape pin-joint pieces (29) (30), some L type pin-joint piece members such as (31) by existing perambulator (1) (promptly as shown in Figure 1), yet it has following shortcoming:

1. each handlebar stem, front wheel bar, rear wheel bar, side pole, bottom bar, back of the body bar all must be through work programmes such as Pipe Cutting, bending shaping, japanning, quite troubles.

2. each member makes up hinged some pin-joint pieces and the rivet of must cooperating mutually and comes riveted hinged, and is quite loaded down with trivial details with regard to fitting work.

3. the combination of each combined wheels also quite bothers.

4. each Qian shape pin-joint piece or L type pin-joint piece all must be shaped and work programmes such as plating through bending, perforation, and ferrous material has easy scratch child's danger.

5. can't do it yourself to assemble.

The purpose of this utility model is to provide a kind of production simple fast speed Pushchair easy to assembly, can reduce production costs, and enhances productivity.

The purpose of this utility model reaches as follows: a kind of Pushchair, comprise a pair of handlebar stem, a pair of front wheel bar, the pair of rear wheels bar, one offside pole, two bottom bars, two back of the body bars, a pair of double-action plate, combined wheels before two, two back combined wheels, some pin-joint pieces, seat cushion cloth, members such as some trips, aforementioned components all adopts ABS(acrylontirile-butadiene-styrene) or PP(polyp-ropylene) impact resistant plastics make, and this each handlebar stem wherein, front wheel bar, all integrally formed on the rear wheel bar have Qian shape or L shaped pin-joint piece, and all be provided with the through hole that can embed described trip on the appropriate location of all members.

Purpose of the present invention can also following mode reach: each described preceding combined wheels and back wheel again all are to be formed by wheel and another the wheel assembly that is installed with trip on its axle center with axis hole.

Advantage of the present utility model is:

1. make assembly working simple and convenient, can finish rapidly, thereby can save the assembler time, cost-cutting is enhanced productivity.

2. customer's assembly working of can doing it yourself to finish.

3. the easy processing of each member can reduce production costs.

Illustrating of accompanying drawing is as follows:

Fig. 1 is the block diagram of existing perambulator.(not comprising seat cushion cloth)

Fig. 2 is the three-dimensional exploded view of a kind of embodiment of the utility model.(not comprising seat cushion cloth).

Fig. 3 is the assembly drawing of the described embodiment of Fig. 2.

As Fig. 2 and shown in Figure 3, a kind of Pushchair of the utility model includes a pair of handlebar stem (51) (52), a pair of front wheel bar (53) (54), pair of rear wheels bar (55) (56), an offside pole (57) (58), two bottom bars (59) (60), two back of the body bars (61) (62), a pair of double-action plate (63) (64), two preceding combined wheels (8), two back combined wheels (9), pin-joint piece (65) (66), seat cushion cloth (101), some trips (71) (72) (73) (74) (75) members such as (76).Aforementioned components is all ABS or the manufacturing of PP impact resistant plastics, and this each handlebar stem (51) (52) wherein, front wheel bar (53) (54), all integrally formed on the rear wheel bar (55) (56) have Qian shape pin-joint piece (81) (82) or a L shaped pin-joint piece (83) (84) (85), on the appropriate location of above-mentioned all members, all offer some through holes again, but corresponding matching embeds trip (71) (72) (73) (74) (75) (76), thereby can make up quickly and easily and finish a kind of Pushchair, in the time of can saving the assembler, the saving member work programme, relative cost-cutting, enhance productivity, even customer's combine and assemble of also can doing it yourself.In addition, each compound wheel (8) (9) of combined wheels (8), two back combined wheels (9) is combined into by two wheels (881) (882), (91) (92) all respectively before of the present utility model two, one of them wheel (881) (91) is installed with trip (811) (911) at the place, axle center, and just can corresponding intercalation enter another wheel (882) (92) with axis hole (figure does not show) and the intercalation combination.

Claims
