Description
Technical field
The present invention relates to steering mechanical field, relate in particular to a kind of steering mechanism.
Background technology
Steering mechanism is generally made up of with yoke 02 fixing end 01, and wherein yoke 02 is provided with rotating shaft, and miscellaneous part is connected to turn
Realizing divertical motion on axle, following three kinds of structures are the most common steering mechanism:
1, refering to Fig. 1, this is the most also to be modal steering mechanism, uses the parts phase that this mechanism is connected with rotating shaft
Can realize the rotation of about 270 ° for yoke 02, shortcoming has two, and one is between yoke 02 and fixing end 01
Turning is 90 ° of intensity differences, long-time uses the risk that there is fracture, its two, use the time length through hole aperture of yoke 02
Place can be by rotating shaft abrasion deformation, the stability that impact rotates.Its three, lack fixing between this structure yoke 02, due to rotating shaft
And the rotation of coupled components over time can cause the distance between the two ends of yoke 02 be gradually increased finally make shaft bending without
Method rotates.
2, refering to Fig. 2, the difference with the first mechanism is, yoke 02 two ends link together, even if advantage is rotating shaft
Rotation with coupled components over time will not result in the distance at yoke 02 two ends to be increased, the stabilized soil pavement that mechanism is overall
Better than the first, shortcoming is, owing to yoke 02 two ends link together, if some position of the parts being connected with rotating shaft is compared to lean on
Nearly rotating shaft, then can be interfered by the position connected between yoke 02 when that it rotating, it is impossible to realize the rotation of 270 °.
3, refering to Fig. 3, most obvious difference is that there are two fixing ends 01 in the third mechanism, when turning to machine with above two structure
When structure needs more to be firmly fixed, use the third mechanism, it is evident that due to the existence of second fixing end 01, with rotating shaft phase
Parts even are more prone to be interfered, because the volume that the third mechanism contrasts the second mechanism more strengthens the when of rotation.
In sum, the strengths and weaknesses of above-mentioned three kinds of mechanisms is the most different, cause they between cannot replace can only be specifically
In the range of use, if needing to realize function corresponding to above-mentioned three kinds of mechanisms will purchase the steering mechanism of three kinds of different structures, because of
It is little to there is range in the steering mechanism of this prior art, in-convenience in use shortcoming.
Summary of the invention
For solving the technical problem that above-mentioned prior art exists, the present invention provides a kind of range more extensively, more easily to turn to machine
Structure.
The technical solution used in the present invention is: provide a kind of steering mechanism, including outer slide and the interior cunning of outer slide sliding plug
Block, the rotating shaft being rotatably assorted with outer slide and inner slide through outer slide and inner slide, slide through inner slide and pass through with outer slide
Alignment pin becomes the contiguous block of removable connection；
Described inner slide lower end is provided with internal thread hole, the slide rail that upper end is conformed with, the guide rail that both sides are conformed with, and middle part is provided with
Insert the manhole rotated for rotating shaft, bottom is provided with shape and contiguous block and coincide the through hole that confession contiguous block is slidably inserted into；
Described outer slide includes connecting portion and support arm；
Described connecting portion upper end is provided with internal thread hole, and bottom surface is provided with and coordinates the upper hopper chute slided with slide rail；
Being provided with inside described support arm and coordinate the sideslip groove slided with guide rail, middle part is provided with inserts, for rotating shaft, the manhole rotated,
Bottom is provided with the positioning through hole coordinating the end chute slided with contiguous block and inserting for alignment pin；
Described contiguous block is the component of bar shape, is provided with the positioning through hole inserted for alignment pin.
The steering mechanism that the present invention uses can substitute for existing three kinds of steering mechanism, specifically, steering mechanism's tool of the present invention
There are three kinds of steering mechanism in the most corresponding background technology of three kinds of use states.
Use state one: inner slide and rotating shaft are applied in combination or outer slide is applied in combination with rotating shaft and can realize in prior art
The function of the first mechanism.
Use state two: outer slide, rotating shaft, alignment pin, contiguous block are applied in combination and can realize the second of the prior art
The function of mechanism, concrete combined method is, is inserted along the end chute of support arm by contiguous block, then it is logical that alignment pin is inserted location
Hole, inserts rotating shaft in the manhole that support arm is corresponding.
Use state three；Outer slide, rotating shaft, alignment pin, contiguous block, inner slide be applied in combination can realize of the prior art
The function of the third mechanism, because the lower end of interior inner slide is provided with, the internal thread hole effect held fixing with prior art is identical all may be used
Fixing with miscellaneous part to be threaded connection, concrete combined method is, first by corresponding with guide rail for the slide rail of inner slide outer slide
Upper hopper chute and sideslip groove insert, then contiguous block is inserted in through hole corresponding to inner slide along the end chute of support arm, then will be fixed
Position pin inserts in positioning through hole, finally rotating shaft is inserted in the manhole that outer slide, inner slide are corresponding.
In the steering mechanism of the present invention, slide rail coordinates, with sideslip groove, the work that can play guiding with location that slides with upper hopper chute, guide rail
With, the steering mechanism of the present invention can select the state needed to be applied in combination according to practical situation.
The present invention can also make following improvement: is provided with the projection of truncated cone-shaped, described truncated cone-shaped at its aperture of the manhole of support arm
Its center of projection be provided with size and manhole same axis with manhole the consistent through hole rotated that inserts for rotating shaft, described
Inner slide is provided with the step that cross sectional shape is identical with the cross sectional shape of truncated cone-shaped projection.So improve and be advantageous in that support arm is circular
At the aperture of through hole, intensity is more preferably difficult to by the rotation abrasion deformation of rotating shaft, it is ensured that the stability that steering mechanism uses for a long time, separately
The outer projection arranging truncated cone-shaped and cross sectional shape can play with its step coincideing and guide and the effect of location.
The present invention can also make following improvement, and the turning between support arm and connecting portion is circular arc.The turning of circular arc relative to
Bigger active force can be born in the turning of originally 90 °.
