Abstract

The utility model relates to a manual toy tricycle which belongs to the toy vehicle. The utility model is composed of a rod for a handle bar, a connecting rod, a front pulley, a seat cushion and a pair of back pulleys, wherein, one end of the connecting rod is connected with the rod of the handle bar, and the other end is provided with the front pulley; the middle part of the connecting rod is movably connected with one end of the seat cushion by a hinge; the other end of the seat cushion is provided with the back pulleys. A person sits on the seat cushion, both feet pedal the middle part of the rod of the handle bar, and hands are used to shake the handle bar leftwards and rightwards to make the tricycle slide forwards.

Description

Manual toy tricycle

The utility model belongs to toy car.

Existing toy car is foot-operated three-wheel vehicle.The purpose of this utility model is to design a kind of hand toys car.

The utility model by vertical handgrip, pipe link, front wheel, seat cushion and back pulley to forming; Pipe link one end is connected with vertical handgrip, its other end device front wheel, and its middle part becomes to flexibly connect with hinge with seat cushion one end; Seat cushion other end device back pulley is right.Pipe link one end generally is welded into the vertical handgrip middle part captives joint, and the shape of vertical handgrip is similar to bicycle handle bar's bar, and pipe link is vertical mutually with vertical handgrip.The front wheel of pipe link other end device can be two pulleys that are loaded on pipe link other end both sides, and promptly pulley is right; Also can be single the pulley that is loaded on the pipe link other end, as long as the directed block of device on the support of this single pulley does not slide backward pulley.Above-mentioned hinge can be made up of hollow rotating shaft that is fixed in pipe link middle part and the trepanning that passes seat cushion one end, and said trepanning is loaded on the said hollow rotating shaft, and it is fastening that usefulness is passed the fastener of hollow rotating shaft; Also can be the trepanning composition that is fixed in the hollow rotating shaft of seat cushion one end and passes the pipe link middle part, said trepanning is loaded on the said hollow rotating shaft, and be fastening with the fastener that passes hollow rotating shaft.For making above-mentioned hinge through more flexible, can pass seat cushion one end, the upper and lower surface that is placed in the trepanning on hollow rotating shaft device respectively is placed in bearing on the hollow rotating shaft; Perhaps the bearing that is placed on the hollow rotating shaft is housed passing upper and lower surface pipe link middle part, that be placed in the trepanning on the hollow rotating shaft respectively.

When playing this car, the people is sitting on the seat cushion, and both feet are stepped at vertical handgrip middle part, and both hands are held vertical handgrip gloves, and with the hand handlebar that rocks from side to side, front wheel drives seat cushion by hinge and moves ahead along with wigwag motion advances, and is right because the seat cushion other end is equipped with back pulley.People on the seat cushion also advances.Both hands shake that the speed of handlebar is fast more, and hand-car also advances fast more, and can at will change working direction by trip player's wish.This toy safety, flexible, novel and interesting.

Fig. 1 is the lateral plan of the utility model embodiment, and as Figure of abstract;

Fig. 2 is the birds-eye view of the utility model embodiment;

Further specify below in conjunction with accompanying drawing.

Among Fig. 1, Fig. 2, vertical handgrip 1 curves the rod-shape as bicycle handle bar by steel pipe, and pipe link 2 is a ∏ shape, is stamped to form ∏ shape pipe link one end and vertical handgrip welding with steel plate.The a pair of pulley 4 of both sides device of ∏ shape pipe link 2 other ends, with wheel shaft and nut device, pulley by bearing and the rim that tightly is placed in outside the bearing constitute, rim can be made with highstrenghtpiston's pressure injection.The rotating shaft of a hollow steel pipe as hinge 3 welded near the position of front wheel in centre at ∏ shape pipe link.Seat cushion 5 ABS plastic injection moulding, its front one end has through pan, and two downsides of its back one end have the hole of device back pulley axle, and with wheel shaft and a pair of back pulley 6 of nut device, back pulley 6 structures are identical with front wheel 4.Be inserted in a surface bearing in above-mentioned hinge rotating shaft earlier, the pan with the seat cushion front end is inserted in the hinge rotating shaft then, is inserted in the another surface bearing again, and is fastening with nut.Can place rubber and plastic sleeve pipe etc., two end device handle covers in handlebar stem step part.

Above-mentioned hinge arrangement also can be fixed in the hinge rotating shaft on the seat cushion, and pan is opened on pipe link; Be installed on front wheel on the pipe link to also can changing single pulley into, if on pulley bracket the directed link stopper of device, it is not slided backward.
