Abstract

The utility model discloses a three-wheel scooter, which comprises a handle (2), a stand pipe (3), a front wheel (4), a folding seat (5), a left and right leg pipe (6), a fork assembly (8), a back wheel (10), a brake gear and a foot treadle (7), wherein the ends of the left and right leg pipe (6) are respectively provided with a connecting seat (13); the fork assembly (8) comprises a back wheel fork (16), a hollow connecting shaft (12), a bearing (15) and a bearing pressing plate (14); the hollow connecting shaft (12) can be rotatably arranged on the back wheel fork (16) through the bearing (15) and the bearing pressing plate (14); the back wheel (10) can be rotatably arranged on the back fork (16); and the hollow connecting shaft (12) is fixed on the connecting seat (13) in an inclined way at an included angle of 64 to 66 degrees with the horizontal plane. Adopting the structure, the utility model solves the defects of inflexible back wheel and poor brake, and has the advantages of simple and reasonable structure, flexible and easy turning, safe use and the like.

Description

Three-wheel scooter

Technical field

The utility model relates to a kind of amusement and recreation exerciser, particularly a kind of three-wheel scooter.

Background technology

Three-wheel scooter is a kind of exerciser that had just just come into vogue in recent years, is mainly used in the gymnastic apparatus of amusement and recreation, also can be used for traffic means of transport temporarily.Three-wheel scooter except of many uses, interesting and recreational strong, also have advantages such as volume is little, in light weight, cost is low, easy to carry, therefore, just be subjected to the joyful of consumers in general since the listing always.Three-wheel scooter is constantly brought forth new ideas in evolution and is improved, and product constantly is optimized and is perfect, has produced various different design, and has developed the corresponding product of suitable all ages and classes section.But existing three-wheel scooter in use still has the following disadvantages: the one, and existing three-wheel scooter is generally based on back-wheel drive, trailing wheel adopts the structure of vertical rotation hinge and elastic element forced resetting, effect owing to the elastic element forced resetting in the trailing wheel reseting procedure has increased the driving resistance of trailing wheel, thereby influences the coasting speed and the fluency of Kickboard Scooter; The 2nd, existing three-wheel scooter is because the trailing wheel structural reason generally adopts front wheel brake, and the shortcoming of Front brake is not steady, weak effect, has potential safety hazard.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not find reasonably solution so far as yet.

Summary of the invention

In order to overcome the problems referred to above that existing three-wheel scooter exists, the purpose of this utility model provides a kind of simple and reasonable, trailing wheel and rotates three-wheel scooter flexible, easy to operate, safe in utilization.

The technical scheme that its technical matters that solves the utility model adopts, it comprises handle, standpipe, front-wheel, foldable base, left and right sides pin pipe, wheel fork assembly, trailing wheel, brake gear, be fixed with stretcher respectively on the pin pipe of the left and right sides, the end of described left and right sides pin pipe is respectively equipped with Connection Block; Described wheel fork assembly comprises rear wheel fork, hollow adapter shaft, bearing, bearing plate, hollow adapter shaft is by bearing and bearing plate is rotating is arranged on the rear wheel fork, trailing wheel is rotating to be arranged on the rear wheel fork, and hollow adapter shaft tilts to be fixed on the Connection Block to become 64-66 ° angle with horizontal surface.

Described brake gear comprises brake handgrip, brake connection lead, brake facing, the brake handgrip is arranged on the handle, brake facing is hinged between the fork sheet of rear wheel fork, brake facing is corresponding with trailing wheel, brake connection lead one end passes hollow shaft and is connected with brake facing, and the other end passes left and right sides pin pipe and is connected with the brake handgrip.

After adopting said structure, the utility model has following advantage and effect: the one, because hollow adapter shaft becomes 64-66 ° angle to be obliquely installed with horizontal surface after, rear wheel fork and trailing wheel also can be done the correcting action automatically under the effect that does not have elastic element, it is more flexible that trailing wheel is rotated, and smoothness when Kickboard Scooter slides, speed are fast.The 2nd, after the employing rear brake structure, stop by the front-wheel list, change the trailing wheel dual brake into, braking effect has obvious improvement, has also overcome the jiggly defective of front brake simultaneously.
