Description

Pram

This practicality one is novel to relate to a kind of perambulator.

The finding perambulator three-wheel vehicle, two that is high center of gravity is taken turns little bicycle and four-wheel waggon in the market, and exhausted rare steering hardware to it is simulated the perambulator of roadlice bearing circle, the storage battery car steering hardware in park adopts the lever transmission, bearing circle can only be swung in 90 ° of angular ranges, add that car is very heavy, valency is expensive, be difficult to popularize.

The purpose of this utility model provides a kind of its steering hardware simulated automotive bearing circle, flexible and in light weight, safety, easy perambulator of price.

In order to achieve the above object, the utility model is achieved in that and is provided with seat on vehicle body, under vehicle body, be respectively equipped with front-wheel and trailing wheel, it is characterized in that: big front axle is located at the front that vehicle body is positioned at seat, the rotating shaft of bearing circle is connected with big front axle and is rotatable, and rotating shaft is provided with the steering hardware that can change the front-wheel direction when it rotates.

The utility model also has, and steering hardware comprises winch, rope, drive link and the steering shaft of wiring; The winch and the rotating shaft of wiring are fixed, and rope is around thereon, captive joint with the two ends of drive link in the two ends of rope, and an end and the drive link of steering shaft are hinged, and rotating front-wheel is housed on the other end, and the bending section of steering shaft also is connected with big front axle and is rotatable.

The utility model compared with prior art has: its steering hardware novelty, flexibly, and it is simple and reliable that feel resembles automobile during operation, meets children's nature, tempers children and start maneuvering ability; Cheap, manufacture easily.

Below in conjunction with accompanying drawing the utility model is done an into detailed description:

See figures.1.and.2, be provided with seat 3 on vehicle body 2, be respectively equipped with front-wheel 1 and trailing wheel 4 for 2 times at vehicle body, the radius of front-wheel 1 is greater than the radius of trailing wheel 4; Big front axle 8 is fixed on vehicle body 2 and is positioned at seat 3 fwds below, and the rotating shaft 6 of bearing circle 5 is connected with big front axle 8 and is rotatable; The winch 7 of wiring is fixed in the rotating shaft 6; Rope 9 as shown in Figure 5, in order to increase the friction of rope 9 and winch 7, is avoided skidding on winch 7, winch 7 stage casings radially be provided with two holes 12, rope 9 passes these 2 holes later on respectively around the both sides in 2 holes; Also available holding screw directly is fixed on rope 9 on the winch 7, and the two ends of rope 9 are separately fixed at the two ends of drive link 10; As shown in Figure 3, an end of steering shaft 11 is equipped with rotating front-wheel 1, and an end of the other end and drive link 10 is hinged, and the two ends of big front axle 8 have hole 13 radially, and the bending section of steering shaft 11 passes this hole 13 and rotatable.When rotating shaft 6 is rotated, because of winch 7 and rotating shaft 6 are fixed, winch 7 also rotates so, again because of being wound with rope 9 on the winch 7, the centre portion of rope 9 and winch 7 is fixing, and its two ends are fixed with drive link 10 two ends respectively, so when winch 7 cws or when rotating counterclockwise, rope 9 is also turned left or right pulling, therefore also drives drive link 10 and turns left or move right.Also hinged because of drive link 10 and steering shaft 11, when drive link 10 sway, steering shaft 11 is swung, therefore also just drive front-wheel 1 and turn to.Can be provided with safety strap 14 on front chair 3, back seat 3 is provided with pushing hands 15.

Claims (2)

1, a kind of perambulator, on vehicle body 2, be provided with seat 3, be respectively equipped with front-wheel 1 and trailing wheel 4 for 2 times at vehicle body, it is characterized in that: big front axle 8 is located at the front that vehicle body 2 is positioned at seat 3, the rotating shaft 6 of bearing circle 5 is connected with big front axle 8 and is rotatable, and rotating shaft 6 is provided with the steering hardware that can change the front-wheel direction when it rotates.

2, perambulator according to claim 1 is characterized in that: steering hardware comprises winch 7, rope 9, drive link 10 and the steering shaft 11 of wiring; The winch 7 of wiring is fixing with rotating shaft 6, rope 9 is on winch 7, captives joint with the two ends of drive link 10 in the two ends of rope 9, and an end and the drive link 10 of steering shaft 11 are hinged, rotating front-wheel 1 is housed on the other end, and the bending section of steering shaft also is connected with big front axle 8 and is rotatable.
