Description
One, technical field
The utility model relates to a kind of parts of three-wheel Rocking cycle, particularly a kind of rocking equipment of three-wheel Rocking cycle.
Two, background technology
The rocking equipment of existing three-wheel Rocking cycle generally all adopts the elastic deformation of rubber and certain rotation, reaches and waves the purpose of advancing, and the main shortcoming that exists has: the one, and the rubber deformation amount is little, influences the performance of car load; The 2nd, rubber weares and teares easily, wears out, and service life is short; The 3rd, rocking equipment can't fold, and volume is big, brings many inconvenience for packing, transportation and storage; The 4th, do not have Telescopic, wheel base from size can not adjust, can not simultaneous adaptation adult and child's use.
Three, summary of the invention
For the above-mentioned disadvantage that the rocking equipment that overcomes existing three-wheel Rocking cycle exists, the utility model provides a kind of and rotates flexibly, long service life, can fold and can regulate wheel base from the rocking equipment of three-wheel Rocking cycle.The technical scheme that its technical matters that solves the utility model adopts comprises front-wheel support tube, left and right sides rocking arm, be fixed with upper bracket and undersetting on the described front-wheel support tube, upper bracket is provided with the two-way joint of rotation, the top of left and right sides rocking arm is provided with ball cap, ball cap is provided with the bulb that cooperates with it, the connecting arm of bulb is fixed on the two-way joint of rotation, and the bottom of left and right sides rocking arm is connected with undersetting by bindiny mechanism.
Described bindiny mechanism comprises connection lining, external screw rod, inner screw, spring and spring cover, connecting lining is arranged on the undersetting, external screw rod and inner screw are successively set on the rocking arm of the left and right sides by spring and spring cover, and external screw rod connects by screw thread fit in being connected lining with inner screw.
The extension of described left and right sides rocking arm is provided with and left and right sides pedal bonded assembly telescopic, and telescopic is provided with pilot pin.
Described external screw rod and inner screw are provided with and tighten nut and knurling handle.
After adopting said structure, the upper bracket of front-wheel support tube is connected with bulb on the rocking arm of the left and right sides by the two-way joint of rotation, and the bottom of left and right sides rocking arm is connected with undersetting by bindiny mechanism, and deflection is convenient, it is more flexible to turn to; Can realize conveniently that by bindiny mechanism car load is folding, can reduce packaging volume, be convenient to transportation, storage; By the distance between the conveniently adjusted front and back wheel of the telescopic on the extension of left and right sides rocking arm, use with the people who adapts to different heights; Have simple and compact for structure, turn to flexibly, folding and flexible convenient, advantage such as the life-span is long.
