Technical field

It the utility model is related to body-building recreation apparatus technical field, more particularly to a kind of swing car.

Background technology

Existing swing be all it is fixed, it is safe, but its motion mode of swing is more single, it is recreational relatively low, and And body-building effect is also bad；Current various scooters, swing car, bicycle are liked by children deeply, recreational relatively strong, can be with Move on the ground, but these cars are driven by strength of one's legs, it is necessary to grasp certain skill for new hand, and And the translational speed such as scooter is very fast, potential safety hazard be present.

Utility model content

The utility model carries to solve the problems, such as the recreational deficiency of various scooters of the prior art, be difficult to manipulation A kind of recreational strong, swing bassinet structure that operation difficulty is low, safe to use is supplied.

To achieve these goals, the utility model adopts the following technical scheme that：

A kind of swing bassinet structure, including a front-wheel and two trailing wheels, described front-wheel are provided with front-wheel support, after two Connected by rotating shaft between wheel, connected between the front-wheel support and rotating shaft by hanging oneself from a beam, described overarm is provided with cross bar, institute The cross bar stated is vertical with overarm to be fixedly connected, and the both ends of the cross bar are provided with hoist cable, are hung with seat between the lower end of hoist cable, institute The upper end for stating front wheel frame is provided with handlebar, is provided between front axle and the lower end of front-wheel support and is used to prevent front-wheel from retreating unidirectional Position-limit mechanism.User sits on the seat, and both hands grip handlebar respectively, and human body and the entirety of vehicle seat position one, the external force being subject to are Zero, both hands are enforced seat and are moved rearwards（I.e. swing swings backward）, human body produces a momentum backward, according to the conservation of momentum Law, to keep the conservation of momentum, the rolling friction between wheel and ground is ignored for now swing car forward movement；Both hands are drawn Motor-car handle, human body and seat travel forward（I.e. swing swings forward）, now swing car integrally produce the trend moved after one, still It is now force of sliding friction between wheel and ground because unidirectional position-limit mechanism limitation front-wheel is moved rearwards, the force of sliding friction The balance of swing car is broken, the momentum of swing car backward has been balanced out, now swing car stops；Above-mentioned action is repeated, from And the intermittent reach of swing car is realized, recreational strong, operation difficulty is low；Three wheels, overall appearance, stability is good, satisfies the need Face is adaptable, turns to maneuverability.

Preferably, described overarm C-shaped in configuration, the front end of the front-wheel support is provided with rotation seat, the overarm Front end is rotatablely connected with rotation seat, and the rear end of the overarm is fixedly connected with the middle part of rotating shaft.Hang oneself from a beam C-shaped, integrated beauty See, uniform force.

Preferably, described overarm includes some bows, the end of bow is provided with snap joint, adjacent two Connected between bow by snap joint.Overarm can quickly be split, and be easy to carry after fractionation；Bow can be by quick Joint quickly connects, and will soon ressemble.

Preferably, the upper end of the front-wheel support is provided with sliding sleeve, the middle part of the handlebar is fixed with slide bar, described Slide bar and sliding sleeve between be slidably connected, the outside of the sliding sleeve is provided with locking bolt.Sliding sleeve, sliding sleeve can adjust the height of handlebar Degree, to adapt to different crowds.

Preferably, the lower end both sides of the seat are equipped with foot-driven lever.After user sits on the seat, bi-pedal is in pin On treadle, it is easy to both hands to have an effect.

Preferably, described unidirectional position-limit mechanism is flywheel, external tooth and the front-wheel support of flywheel are bolted, and are flown The endoporus of wheel and one end of front axle are fixedly and coaxially connected.Flywheel is standard component, and stability is good, and cost is low.

Preferably, described unidirectional position-limit mechanism includes ratchet, ratchet set, the periphery of ratchet is provided with ratchet, institute The ratchet stated is fixedly connected with one end of front axle, and the lower end of the front-wheel support is provided with terminal pad, the side of the ratchet set It is fixedly connected with terminal pad bolt, the another side of ratchet set is provided with end cap, and some ratchets are provided with the inwall of the ratchet set, Stage clip is provided between the ratchet and pawl disk.Realized by ratchet and pawl arrangement unidirectional spacing.

Preferably, the outside of the ratchet set is provided with turning set, the ratchet, which puts to be provided with the corresponding position of ratchet, to be drawn String holes, the outer end of the ratchet are provided with steel wire rope, and one end of the steel wire rope is fixedly connected with ratchet, and the other end of steel wire rope is worn Fairlead is crossed to be connected with turning set；The outside of the turning set is provided with cursor, and described handlebar is provided with reversing handle, described Reversing handle on be connected with drag-line, the other end of the drag-line and the outer end of cursor connect.Because swing car is unidirectionally limiting It can only be moved forward in the presence of the mechanism of position, car could be stopped in place by moving back and forth regulation before and after parking usually requires, similarly, Swing car is parked in corner, it is necessary to movable conciliation is also required to when being shifted out use to remove car, unidirectional position restrainer It is difficult that structure causes swing car parking to be picked up the car；In this structure, it is necessary to when stopping, picking up the car, reversing handle is pulled, reversing handle passes through drawing Rope, cursor drive turning set to rotate an angle, pull ratchet by steel wire rope when turning set rotates, now ratchet and ratchet Separation, unidirectional position-limit mechanism release, and now swing car can just move forward and backward, consequently facilitating parking, pick-up；Unclamp reversing handle Afterwards, ratchet automatically resets unidirectional spacing with ratchet engagement realization, very easy to use.

Preferably, the lower end inside of the front-wheel support is provided with guide holder, described drag-line passes through guide holder, on drag-line Position between guide holder and cursor is provided with back-moving spring, and described terminal pad is provided with cursor limited block.Reset Spring is easy to turning set to reset, and cursor limited block is used for the extreme position for limiting cursor, prevents cursor from turning over head.

Preferably, the corresponding position on the inwall of the turning set with steel wire rope is provided with arc escape groove.Turning set rotates When, part steel wire rope can enter turning set and ratchet set between position,

Arc escape groove provides space for this section of steel wire rope.

Therefore, the utility model has the advantages that：（1）Overall structure is attractive in appearance, stability is good, safe to use；（2） Turn to maneuverability；（3）Dismantle, be easy to assembly, being easy to carry；（3）Coordinate reversing handle during parking, quickly can stop swing car In place；Coordinate reversing handle during pick-up, pick up the car more smooth.
