Description
Technical field
The utility model belongs to bicycle assembly parts technical field, particularly relates to a kind of integrated children cycle frame.
Background technology
Child's bicycle the children of of the right age 4 to 8 years old ride, toy one, for children provide ride enjoyment, exercise the body and the mind, obtain liking of the head of a family and children.Structurally, child's bicycle also possesses all parts of adult bicycle, and these parts are considered the feature and security requirement etc. of children's torso condition and needed to carry out brand-new design, especially will note the brake lever size of rim brake, the whole height etc. of vehicle body.
Existing child's bicycle structurally comprises bicycle frame device, vehicle frame is generally obtained by section bar welding processing, processing technology comprises the processing steps such as the cutting of section bar, bending, welding, not only the course of processing is loaded down with trivial details, and cause qualifying point to increase, especially solder joint increases, so just for vehicle frame brings structural labile factor, namely there is potential solder joint abnormal sweating, the possibility of solder skip, cause potential potential safety hazard.Meanwhile, its outshot of the vehicle frame of labyrinth is more, easily produces injury of colliding with.
Utility model content
The utility model provides the integrated children cycle frame that a kind of structure is simple, processing technology is succinct, structural strength is high, bulk flow line style is good for solving in known technology the technical matters that exists.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is: the crossbeam that a kind of integrated children cycle frame comprises inclination, rear portion becomes Y shape bifurcated, front fork tube is installed the front portion of crossbeam is affixed, affixedly in the front end of crossbeam is provided with that rear end with the adapter plate of multiple connecting bore, each bifurcated is affixed is provided with dropout; Below in the middle part of crossbeam is connected with support tube, is provided with bottom bracket axle the lower end of support tube is affixed; Also comprise top be provided with seat cushion, the seat of V-arrangement, the front end of seat is articulated and connected between the top of two the bifurcated bodys in crossbeam rear portion, and between the middle and upper part of two the bifurcated bodys in crossbeam rear portion, also erection is connected with and carries out spacing cushion block to seat.
Advantage of the present utility model and good effect are: the utility model provides a kind of integrated children cycle frame of structure design advantages of simple, compared with existing body frame structure for automotive, the technical program is by optimizing the structure of crossbeam, make it the function having many structures such as the crossbeam of traditional vehicle frame, vertical fork, chain stay and seat pipe concurrently, simplify integral structure, more meet airflow design.This Children's Bicycle Frame after optimization possesses less constituent elements, therefore processing technology is more succinct, and qualifying point is as less in the amount of solder joint, makes the overall construction intensity of vehicle frame higher.Because the parts comprised are less, the bulge-structure on vehicle frame surface is less, also just can avoid colliding with to children's torso, effectively avoid personal injury.The design of the integral type vehicle seat that can vert is more roomy comfortable compared with traditional vehicle seat, improves the level of comfort of riding.
Preferably: cushion block comprises the affixed pedestal be arranged between bifurcated body middle and upper part, two, crossbeam rear portion, is connected with the cushion rubber of quality of rubber materials at the top of pedestal.
