Summary of the invention
Object of the present invention is that a kind of sitting posture skibob that is similar to the such slide action of sled and makes it to move ahead will be provided.The object of the present invention is achieved like this: sitting posture skibob, comprise vehicle body, two forks, two handles, seat pipe, saddle, two trailing wheels and three cardan wheels, it is characterized in that: vehicle body is that the car beam front end of a rear portion band bending connects a castor base, the front part sides of car beam is respectively welded with upper and lower flute profile stamping with holes, two flute profile stampings are rotationally connected two forks by two pairs to lock bolt, the bottom of two fork outer ends is connected with two cardan wheels, the top of two fork outer ends is connected with two foldable base, in two foldable base, be rotationally connected two handles, a pair of perforation is arranged at car deflection of beam bottom, to being connected with a rear axle in perforation, the two ends of rear axle connect two trailing wheels, the top at Che Liang rear portion connects a foldable base, foldable base and seat pipe are rotationally connected, seat pipe top connects saddle, the castor base below of car beam front end is connected with cardan wheel.
The invention has the beneficial effects as follows: the present invention has several playing methods, it can be put after making two forks simultaneously this car is moved ahead with the simultaneously rear handle of two hands, also can with two hands alternately after handle and after making two forks alternately pendulum this car is moved ahead, when ingenious simple, the low cost of manufacture of structure of the present invention, folding gathering in, volume is little.

The specific embodiment
According to Fig. 1, described sitting posture pendulum pin car comprises vehicle body 1, fork 2, handle 3, seat pipe 4, saddle 5, trailing wheel 6 and cardan wheel 7;
Described vehicle body 1, comprise car beam, castor base, flute profile stamping, foldable base, toe board and rear axle, the described described castor base of car beam front end welding, the back lower place of described car beam connects described rear axle, the described flute profile stamping of each welding of the both sides of described car beam front portion, the described foldable base of top welding at described Che Liang rear portion, described foldable base is that both sides are with holes, the U font stamping of top band gap, the top of described car beam front portion is also connected with toe board.
Described fork 2, comprise transverse tube, rotating cylinder, foldable base and castor base, the described rotating cylinder of the inner welding of described transverse tube, described rotating cylinder is the cartridge that a bearing is respectively inlayed at upper and lower two ends, the described castor base of outer end welding of described transverse tube, described castor base is circular tube shaped parts with threaded hole, described castor base slightly becomes right-falling stroke picture to retread, described top, transverse tube outer end is welded with described foldable base, described foldable base is that both sides are with holes, the U font stamping of top band gap, rotating cylinder described in two of fork 2 described in two, by lock bolt is rotated and is connected with two flute profile stampings of described vehicle body 1.
Described handle 3 is that a little pipe is welded in a bottom, the top of little pipe is with a pipe to perforation parallel with little pipe, the pore of described handle 3 bottoms, by the foldable base of lock bolt and described fork 2 is rotationally connected, there is a slotted hole described handle 3 bottoms to the vertical of perforation, described handle 3 bottoms are to penetrating cylinder with threaded hole in perforation, in the tapped bore of cylinder, twist and be connected to band bolt, be with the position of bolt is corresponding with the gap of described fork 2 foldable base, the top of described handle 3 is socketed with grip.
Described seat pipe 4, that a little pipe is welded in a bottom, the top of little pipe is parallel with little pipe to perforation with one, and the pipe of top band pipe clamp, the pore of described seat pipe 4 bottoms, by the foldable base of lock bolt and described vehicle body 1 is rotationally connected, there is a slotted hole described seat pipe 4 bottoms to perforation vertical, described seat pipe 4 bottoms are to penetrating cylinder with threaded hole in perforation, in the tapped bore of cylinder, twist and be connected to band bolt, be with the position of bolt is corresponding with the gap of described vehicle body 1 foldable base, described saddle 5 is connected in the top of described seat pipe.
Described trailing wheel 6 is PU wheels of plastic wheel hub, and the core wheel of described trailing wheel 6 has two bearings, and the trailing wheel 6 described in two is socketed and uses the resistance to bolt that falls to pin by the bearing of its core wheel and the two ends of described vehicle body 1 rear axle.
Described cardan wheel 7, it is the endoporus that a bolt connects a bearing, the external diameter of one bearing is encased, also rivets by a metal wheel fork and a metal ring, on one metal wheel fork, by being connected with to a PU, lock bolt takes turns, cardan wheel 7 described in one is done to twist by the bolt at its top and the castor base of described vehicle body 1 front end and is connect, and the cardan wheel 7 described in two is done to twist by two castor bases of fork 2 outer ends described in the bolt and two at its top and connect.
