Abstract
The invention discloses a front fork of a bicycle. The front fork comprises a left fork leg and a right fork leg, and is characterized in that upper ends of the left fork leg and the right fork leg respectively extend to constitute a left standpipe and a right standpipe; and the left standpipe and the right standpipe have semicircular cross sections and are spliced to constitute a standpipe. According to the front fork disclosed by the invention, since the upper ends of the fork leg and the right fork leg extend to constitute the left standpipe and the right standpipe, the left standpipe and the right standpipe are matched into a circular standpipe through a threaded structure and a positioning structure, so that two reinforcing ribs are added in the middle of the standpipe, the strength of the standpipe is improved, and the standpipe is more aesthetic and light compared with the traditional welding structure.
Description
Technical field
The present invention relates to a kind of bicycle, be specifically related to a kind of bicycle front fork.
Background technology
Current society, bicycle is a kind of vehicle that generally use, and claims bicycle again.Bicycle mainly is made up of parts such as vehicle frame, front fork, handlebar, saddle, front forked assembly and wheels; Wherein front fork is in position, the place ahead in bicycle structure; Mainly by about the standpipe on two fork blades and top constitute; Standpipe upper end is used to connect the handlebar parts, about two fork blades be arranged at the front vehicle wheel both sides respectively and cooperate with it, form the steering swivel system of bicycle.
Yet along with bicycle in continuous development towards the technology path of high-grade, fashion; Technological requirement to car load is also increasingly high; Traditional bicycle front fork is iron employing welding process mostly; With about two fork blades and standpipe weld together, thereby constitute a complete bicycle front fork.Yet find that in the use of reality the front fork intensity of this kind structure is not high, nor enough attractive in appearance, need a large amount of manual work welding, the product fraction defective is high, and then has limited it greatly and in senior car, promoted the use of.
Summary of the invention
Goal of the invention of the present invention provides a kind of bicycle front fork, through the improvement to structure, reduces part, improves the intensity of bicycle front fork, and more both artistic and practical.
For reaching the foregoing invention purpose; The technical scheme that the present invention adopts is: a kind of bicycle front fork; Comprise left side fork leg and right fork leg; Said left fork leg and right fork leg upper end extension constitute left standpipe and right standpipe respectively, and said left and right standpipe cross section is semicircle, and said left and right standpipe is spliced to form standpipe.
Further technical scheme is provided with screw in the middle part of the said riser top ends.
Further technical scheme, one of them standpipe inboard of said left standpipe and right standpipe offers fixture block, cooperates on another standpipe to offer draw-in groove, and left and right standpipe engages with draw-in groove through fixture block and is spliced to form standpipe.
In the technique scheme, a kind of bicycle front fork comprises left side fork leg; Right fork leg, said two fork legs extend upward two and half standpipes about formation respectively, and extendible portion is designed to semi-circular shape; Two semicircles of said left standpipe and right standpipe are spliced to form the vertical tube of front fork of a complete circle each other; The standpipe of said front fork by about the splicing of two semicircle standpipes, has had more two reinforced ribs in the middle of the standpipe thus, strengthened the impact resistance of vertical tube of front fork greatly; Improved the safety factor of bicycle; The riser upper end center is provided with a tapped bore, is used for being threaded of standpipe dog bolt, is provided with the fixture block and the draw-in groove of mutual concavo-convex engaging between two semicircles in left and right standpipe bottom.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
1. the present invention adopts left side fork leg to extend semicircle with right fork leg through the upper end and is spliced to form standpipe each other, realizes that two parts substitute three traditional parts, and does not need welding, can practice thrift cost of labor by the full institutionalization production of Realization by Machine;
2. the present invention is simple in structure, and is easy to install, improved the intensity of standpipe, alleviated weight, and profile is more attractive in appearance.
Description of drawings
Fig. 1 is a left side fork leg structural representation in the embodiment of the invention one;
Fig. 2 pitches leg texture edge scheme drawing for the embodiment of the invention one right-of-center in political views;
Fig. 3 is a standpipe spliced structural representation in the left and right sides in the embodiment of the invention one.
Wherein: 1, left side fork leg; 2, right fork leg; 3, left standpipe; 4, right standpipe; 5, screw; 6, fixture block; 7, draw-in groove.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Embodiment one: referring to shown in Fig. 1 to 3; A kind of bicycle front fork comprises left side fork leg 1 and the right leg 2 of pitching, and said left side fork leg 1 and right fork leg 2 upper ends extension constitute left standpipe 3 and right standpipe 4 respectively; Said left and right standpipe cross section is semicircle; Said left and right standpipe is spliced to form standpipe, and said riser top ends middle part is provided with screw 5, and two and half screws of correspondence position are spliced this screw on the left and right standpipe by laying respectively at.Said left standpipe inboard offers fixture block 6, cooperates on the said right standpipe 4 to offer draw-in groove 7, and left and right standpipe engages with draw-in groove through fixture block and is spliced to form standpipe.
This structure through the standpipe of location structure splicing composition front fork, puts the headstock bowl group of bicycle between left and right standpipe in use; Standpipe socket under the constraint of bowl group inner ring of splicing makes 2 semicircles be spliced to form a firm standpipe force structure each other, is installed in the head pipe of bicycle; The standpipe upper oral part presses gland; The locking dog bolt is promptly accomplished and is installed, and realizes the function of bicycle front fork.
Embodiment two: a kind of bicycle front fork; Be used for Electrical Bicycle; Its agent structure is identical with embodiment one, and left side fork leg is pitched in the fork blade in the leg with the right side motor is installed, and motor is provided with miniature gears towards the axle of wheel one side; Miniature gears and the bull gear engagement that is fixedly connected on the wheel rim are realized the transmission of Electrical Bicycle.
Embodiment three: a kind of bicycle front fork; Be used for Electrical Bicycle, its agent structure is identical with embodiment one, and left side fork leg is a short-leg with a right fork blade of pitching in the leg; On short-leg, be connected and installed with motor, the housing of motor constitutes a complete front fork with fork blade.Motor is provided with miniature gears towards the axle of wheel one side, and miniature gears and the bull gear engagement that is fixedly connected on the wheel rim are realized the transmission of Electrical Bicycle.
