Two wheel scooters of round steel body framwork
Technical field:
The present invention relates to a kind of Kickboard Scooter, particularly a kind of two wheel scooters of round steel body framwork.
Background technology:
The Kickboard Scooter that existing market children ride is all generally that this just exists this several large problem with the body framwork made by tubulose section bar, one, the connection of front fork and front head tube must with seven bowls; The two car necks be connected with front head tube, are connected with body forward structure and must adopt folder, and be welded on the front portion of vehicle body; Three, back vent must be welded in the rear portion of vehicle body, and back vent is again by being connected with trailing wheel lock bolt; Four, front fork is mixed seven bowls again by front fork tube and is connected with front head tube, then front fork is installed again vertical; So, the Kickboard Scooter of slight cheapness is also so complicated, and this is concerning the price of labour power more and more higher today, be do not have completely necessary.
Summary of the invention:
Object of the present invention, be to provide a kind of structure simple, cost is lower, two wheel scooters of the round steel body framwork that intensity is higher.Technical scheme of the present invention is: two wheel scooters of round steel body framwork, comprise vehicle body, handlebar, front fork, front-wheel, trailing wheel and brake, it is characterized in that: vehicle body comprises round steel skeleton, angle steel shape stamping and plastic front board, before and after round steel skeleton, two is bent into hook-shaped, the top of hook is threaded hole, angle steel shape stamping is connected to the middle part of round steel skeleton by spot welding, plastic front board is fixed by bolt and angle steel shape stamping, handlebar comprises handle riser, hand handle and sleeve pipe, sleeve pipe and handle riser welding, the front hook of round steel skeleton inserts in sleeve pipe, and mix packing ring, bolt, round steel skeleton and sleeve pipe are rotatably located, hand is the upper end being installed on handle riser, a front fork is welded in the lower end of handle riser, it is hook-shaped that front fork is that two is bent into, and lower hook end band has the round steel bending part of tapped bore, front-wheel to be installed under front fork on hook, and be furnished with bolt pinning, trailing wheel is installed on the rear hook of round steel skeleton, and be furnished with bolt pinning, brake comprises brake facing and brake frame, brake frame is fixed on the rear portion of round steel skeleton, brake facing is arranged on brake frame, and be furnished with torsion spring, by bullet on brake facing.
The invention has the beneficial effects as follows: the front hook that have employed round steel skeleton coordinates with sleeve pipe, eliminate front fork tube, front head tube, seven bowls and folder, the rear hook that have employed round steel skeleton directly installs trailing wheel, than back vent being installed the simple and material-saving of trailing wheel, have employed the front fork with round steel bending part, with traditional front fork than constructing simpler, more material-saving, and manufacture, install and manually all save.
