Abstract
The utility model provides a front fork axle, nut, flange, stopper body and screw rod including the integral type structure, flange one side links to each other with the nut, and the opposite side links to each other with the screw rod, the screw rod includes interconnect's polished rod section and screw thread section, and the polished rod section links to each other with the flange, stopper body is located the junction of polished rod section and flange, and stopper body is a prism, and the cross section is regular polygon. Stopper body plays spacing effect of splining, like this front fork axle only need when the installation the screw thread section screw on the nut can, the other end is unnecessary to be pressed from both sides tightly, can realize the installation of simplex utensil, has saved the manpower, easy dismounting, work efficiency is high.
Description
Technical field
This utility model belongs to bicycle or electric automobiles, especially a kind of front fork shaft.
Background technology
Front fork component is in position, front, its upper end and handlebar parts in electric motor car or bicycle structure
Being connected, frame part coordinates with front pipe, and lower end coordinates with front spindle unit, forms electric motor car or bicycle
Guidance system.In prior art, front fork shaft, frequently with studs or bolt, at least needs two during dismounting
Individual instrument, otherwise there will be with turning phenomenon.Two of front fork shaft is positioned at front-wheel both sides, needs side to clamp,
Opposite side fastening nut, is limited by work space, often needs two workmans to cooperate, waste of manpower,
Material resources, inefficiency.
Summary of the invention
In view of this, this utility model is directed to fork shaft before one, to solve fork shaft before in prior art
Two instruments, waste of manpower, material resources, ineffective problem is at least needed during dismounting.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
Fork shaft before a kind of, including nut, flange, limit body and the screw rod of integral structure；Described flange
Side is connected with described nut, and opposite side is connected with described screw rod；Described screw rod includes interconnective light
Bar segment and thread segment, described smooth bar segment is connected with flange；Described limit body is positioned at described smooth bar segment and flange
Junction, described limit body is a prism, and cross section is regular polygon.
Further, described screw rod also includes that guide section, described guide section are a round platform, big end and described spiral shell
Stricture of vagina section is connected so that guides accurately, be difficult to stripped thread.
Further, described limit body is centrally located on the axis of described screw rod.
Further, the external dimensions of described limit body is less than the external dimensions of described flange.
Further, the inscribed circle diameter of described limit body cross section is more than or equal to the external diameter of described screw rod.
As preferably, the cross section of described limit body is square, it is simple to processing.
Further, the cross section of described limit body is equilateral triangle.
Further, the cross section of described limit body is regular pentagon.
Relative to prior art, before one described in the utility model, fork shaft has the advantage that limit body
Play the effect of spacing spline, so before fork shaft only need to screw on nut at thread segment, separately when mounted
One end need not clamp, it is possible to achieve either simplex tool is installed, and saves manpower, easy accessibility, and work efficiency is high.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing,
Schematic description and description of the present utility model is used for explaining this utility model, is not intended that this reality
With novel improper restriction.In the accompanying drawings:
Fig. 1 is general illustration of the present utility model；
In figure: 1-nut, 2-flange, 3-limit body, 4-screw rod, 41-bar segment, 42-thread segment, 43-
Guide section.
Detailed description of the invention
It should be noted that in the case of not conflicting, in embodiment in this utility model and embodiment
Feature can be mutually combined.
In description of the present utility model, it is to be understood that term " " center ", " longitudinally ", " horizontal stroke

Flat ", the orientation that indicates of " top ", " end ", " interior ", " outward " etc. or position relationship be based on attached
Orientation shown in figure or position relationship, be for only for ease of description this utility model and simplify description, and not
Be instruction or the hint device of indication or element must have specific orientation, with specific azimuth configuration and
Operation, therefore it is not intended that to restriction of the present utility model.Additionally, term " first ", " second "
Etc. being only used for describing purpose, and it is not intended that instruction or hint relative importance or implicit indicate indication
The quantity of the technical characteristic shown.Thus, the feature defining " first ", " second " etc. can be expressed
Or implicitly include one or more this feature.In description of the present utility model, unless otherwise
Illustrating, " multiple " are meant that two or more.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited,
Term " is installed ", " being connected ", " connection " should be interpreted broadly, and connects for example, it may be fixing,
Can also be to removably connect, or be integrally connected；Can be to be mechanically connected, it is also possible to be electrical connection；
Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, can be the company of two element internals
Logical.For the ordinary skill in the art, can understand that above-mentioned term is at this by concrete condition
Concrete meaning in utility model.
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As it is shown in figure 1, fork shaft before a kind of, including the nut 1 of integral structure, flange 2, limit body 3
With screw rod 4；Flange 2 side is connected with nut 1, and opposite side is connected with screw rod 4；Screw rod 4 includes phase
The light bar segment 41 connected and thread segment 42, light bar segment 41 is connected with flange 2；Limit body 3 is positioned at light
Bar segment 41 and the junction of flange 2, limit body 3 is a prism, and cross section is regular polygon.
Screw rod 4 also includes that guide section 43, guide section 43 are a round platform, and big end is connected with thread segment 42,
Make to guide accurately, be difficult to stripped thread.
Limit body 3 is centrally located on the axis of screw rod 4.
The external dimensions of limit body 3 is less than the external dimensions of flange 2.
