Abstract
The utility model belongs to the field of bicycles and provides a bicycle front fork which comprises a vertical tube (3) and a left front fork (1) and a right front fork (2) which are symmetrically connected to the vertical tube (3), the left front fork (1) and the right front fork (2) are conical pipes of which the upper ends are bent and the diameters of the upper ends are lager than the diameters of the lower ends. The bicycle front fork provided by the utility model has the characteristics of good stability and light weight.
Description
Technical field
The utility model relates to the bicycle field, specifically, relates to a kind of bicycle front fork.
Background technology
The existing bicycle front fork connection modes that the bridging fitting is set between two front fork tubes that adopt, adopt straight tube as intubate more more.Adopt the connection mode of bridging fitting to connect, rocking easily appears in bicycle in the middle of the process of travelling, poor stability.Adopt straight tube as connection pipe, make the vehicle body of bicycle too heavy.
The utility model content
The purpose of this utility model is to provide a kind of bicycle front fork, and bicycle front fork provided by the utility model has good stability, and compares general front fork voluntarily and alleviated weight, makes frame lighter.
To achieve these goals, the utility model provides a kind of bicycle front fork, comprise vertical tube and the left front breeches pipe and the right front breeches pipe that are connected with the vertical tube symmetry, described left front breeches pipe and described right front breeches pipe are the taper pipe that upper end curves, upper end diameter is greater than lower end diameter.
Described left front breeches pipe and described right front breeches pipe are the taper pipe that upper end diameter and lower end diameter ratio are 1.15～1.20:1.
As preferably, described left front breeches pipe and described right front breeches pipe are the taper pipe that upper end diameter and lower end diameter ratio are 1.18:1.
Described left front breeches pipe and described right front breeches pipe adopt integral structure.
Described vertical tube is fixedly connected with described left front breeches pipe, described right front breeches pipe.
Bicycle front fork provided by the utility model has not only solved in the bicycle running process, and easily produce and rock between left and right front fork tube and vertical tube, the shortcoming of poor stability, and alleviated the weight of vehicle body, make to ride lighter.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of bicycle front fork described in the utility model.
The specific embodiment
Below with reference to accompanying drawing, embodiment of the present utility model is described.The element of describing in an accompanying drawing of the present utility model or a kind of embodiment and feature can combine with element and feature shown in one or more other accompanying drawings or embodiment.It should be noted that for purposes of clarity, omitted, expression and description known to persons of ordinary skill in the art parts or processing irrelevant with the utility model in accompanying drawing and explanation.
Below in conjunction with accompanying drawing, the utility model is described further.
Bicycle front fork of the present utility model as shown in Figure 1, comprise vertical tube 3 and the left front breeches pipe 1 and the right front breeches pipe 2 that are connected with vertical tube 3 symmetries, left front breeches pipe 1 is the crooked integrated formed structure be connected in upper end with right front breeches pipe 2, vertical tube 3 is fixedly connected with left front breeches pipe 1, right front breeches pipe 2, left front breeches pipe and right front breeches pipe are the taper pipe of upper end diameter 33mm, lower end diameter 28mm, thickness of pipe 2.5mm, adopt 7 line aluminium alloys as material.
Bicycle front fork of the present utility model has not only solved in the bicycle running process, and easily produce and rock between left and right front fork tube and vertical tube, the shortcoming of poor stability, and alleviated the weight of vehicle body, make to ride lighter.
Although described the utility model and advantage thereof in detail, be to be understood that in the situation that do not exceed the spirit and scope of the present utility model that limited by appended claim and can carry out various changes, alternative and conversion.And the application's scope is not limited only to the specific embodiment of the described process of specification sheets, equipment, means, method and step.The one of ordinary skilled in the art will readily appreciate that from disclosure of the present utility model, according to the utility model, can use and carries out with the essentially identical function of corresponding embodiment described herein or obtain process, equipment, means, method or step result essentially identical with it, that existing and will be developed future.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
