Abstract
The utility model provides a kind of multifunction bicycle front fork, comprise main breeches pipe and secondary breeches pipe, described secondary breeches pipe is flats body, the trailing flank of flats body is stream line pattern curved surface, and the trailing flank of secondary breeches pipe is drawn close to direction, described main breeches pipe axis, the tube wall lower end of the lateral surface of described secondary breeches pipe is connected with two supporting legs by rotating shaft, the upper end of the lateral surface of secondary breeches pipe is provided with a rectangle draw-in groove, the shape of described rectangle draw-in groove and the width of described supporting leg match, for fixing described supporting leg.Secondary breeches pipe in bicycle front fork of the present utility model is flats body, the trailing flank of flats body is stream line pattern curved surface, and the trailing flank of secondary breeches pipe is drawn close to direction, main breeches pipe axis, the stressed of whole front fork is made all to point to car body center, add the binding force of whole bicycle front fork and car body, reduce the resistance in car driving process, on front fork, adding supporting leg simultaneously, adding car body steadiness when parking.
Description
Technical field
The invention relates to vehicle accessory field, is specifically related to a kind of multifunction bicycle front fork.
Background technology
Along with the raising of people's living standard, also more and more higher to the technological requirement of car load, traditional bicycle front fork is iron employing welding process mostly, by two, left and right fork blade and the simple weld together of standpipe, thus the bicycle front fork that formation one is complete.But find in the use of reality, not only intensity is not high for the front fork of this kind of structure, and impact resistant capability is weak, overlong time of riding front fork is yielding, and the junction of front fork and front tyre is easily lax in collision process, poor with car body binding force, bring very large inconvenience to the safety of people.
Summary of the invention
The problem that the invention will solve is to provide the high special-shaped multifunction bicycle front fork of a kind of stability.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of multifunction bicycle front fork, comprise main breeches pipe and secondary breeches pipe, described secondary breeches pipe is flats body, the trailing flank of described flats body is stream line pattern curved surface, and the trailing flank of described secondary breeches pipe is drawn close to direction, described main breeches pipe axis, the tube wall lower end of the lateral surface of described secondary breeches pipe is connected with two supporting legs by rotating shaft, the upper end of the lateral surface of described secondary breeches pipe is provided with a rectangle draw-in groove, the shape of described rectangle draw-in groove and the width of described supporting leg match, for fixing described supporting leg.
The distance of described rectangle draw-in groove and described rotating shaft is greater than the half of described supporting leg height, and is less than the height of described supporting leg.
Described main breeches pipe and secondary breeches pipe are carbon element thin-wall steel tube.
Described supporting leg is that lactoprene material processes through thermoplastic.
The advantage that the invention has and good effect are: the secondary breeches pipe in the bicycle front fork of the invention is flats body, the trailing flank of flats body is stream line pattern curved surface, and the trailing flank of secondary breeches pipe is drawn close to direction, main breeches pipe axis, the stressed of whole front fork is made all to point to car body center, add the binding force of whole bicycle front fork and car body, reduce the resistance in car driving process, on front fork, adding supporting leg simultaneously, adding car body steadiness when parking.
Accompanying drawing explanation
Fig. 1 is the using state structural representation of the invention;
Fig. 2 is the lateral plan of the invention.
Detailed description of the invention
A kind of multifunction bicycle front fork, comprise main breeches pipe 1 and secondary breeches pipe 2, secondary breeches pipe 2 is flats body, the trailing flank of flats body is stream line pattern curved surface, and the trailing flank of secondary breeches pipe is drawn close to direction, main breeches pipe 1 axis, the tube wall lower end of the lateral surface of secondary breeches pipe is connected with two supporting legs 4 by rotating shaft 3, and the upper end of the lateral surface of secondary breeches pipe is provided with a rectangle draw-in groove 5, the shape of rectangle draw-in groove 5 and the width of supporting leg 4 match, for fixing supporting legs 4.Rectangle draw-in groove 5 is greater than the half of supporting leg 4 height with the distance of rotating shaft 3, and is less than the height of supporting leg 4, and main breeches pipe 1 and secondary breeches pipe 2 are carbon element thin-wall steel tube, and supporting leg 4 processes through thermoplastic for lactoprene material.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
