But, in transport or fitting process, locking adjusting mechanism may because of collision, artificial or other unexpected factors and occur loosening, thus cause the upper and lower sleeve pipe relative position of tubing string to change, cause steering column precision when car load assembles to reduce, even cause the consequence that cannot assemble.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of anti-rotation device of steering column, and the technical matters that the utility model solves how to avoid the occurrence positions change before assembling completes of the upper and lower sleeve pipe of steering column.
The purpose of this utility model realizes by following technical proposal: a kind of anti-rotation device of steering column, it is characterized in that, comprise the anti-rotation collar in the form of a ring, the described anti-rotation collar has the connecting portion extended along rotating prevention sleeve Ring current distribution line direction, described connecting portion has the anti-rotating pin extended along anti-rotation collar radial direction.
The principle of work of the anti-rotation device of this steering column is by the design anti-rotation collar and anti-rotating pin, during installation, rotating prevention sleeve ring set is located on steering column, anti-rotating pin is inserted in the preformed hole on steering column on sleeve pipe and steering column case in, make sleeve pipe and case in realize location and there will not be relative sliding or rotation, thus avoid the occurrence positions change before assembling completes of the upper and lower sleeve pipe of steering column; Meanwhile, the anti-rotation collar and anti-rotating pin are structure as a whole or fixed relationship, and the anti-rotation collar can make anti-rotating pin plug-in mounting more stable with steering column flush fit, thus the positioning stablity between the upper and lower sleeve pipe of guarantee steering column.
In the anti-rotation device of above-mentioned steering column, described rotating prevention sleeve Ring current distribution line is crossing with the line of centers of anti-rotating pin and vertical.Adopt above-mentioned design goal to be to ensure that anti-rotation device is installed to the stability on steering column, thus avoid the occurrence positions change before assembling completes of the upper and lower sleeve pipe of steering column.
In the anti-rotation device of above-mentioned steering column, the described anti-rotation collar comprises two curved and outwardly snap rings, is formed with bayonet socket between the end, one end of two described snap rings, and described connecting portion is between the other end end of two snap rings.The anti-rotation collar is facilitated to be installed on tubing string by design bayonet socket, and two snap rings can clamp steering column when mounted, making whole anti-rotation device more stable when being installed on steering column, being conducive to preventing the upper sleeve pipe of steering column and case in position to be moved.
In the anti-rotation device of above-mentioned steering column, the end of two described snap rings has bandy bending segment, rounding off between described bending segment and snap ring, is formed in trumpet-shaped bayonet socket between two described bending segments.By designing trumpet-shaped bayonet socket, the anti-rotation collar is facilitated to be installed on steering column by smooth and easy fast speed.
In the anti-rotation device of above-mentioned steering column, described anti-rotating pin comprises the cylinder being positioned at connecting portion side and the coupling end being positioned at connecting portion opposite side, and described coupling end has connecting bore.By design connecting bore, facilitate the dismounting of whole anti-rotation device.
In the anti-rotation device of above-mentioned steering column, in described connecting bore, be equipped with anti-rotation band.When after steering column general assembly to car load, by pulling anti-rotation band to be left behind by whole anti-rotation device, disassembling section is quick and convenient.
Compared with prior art, the anti-rotation device of this steering column has the following advantages: by the design anti-rotation collar, anti-rotating pin and anti-rotation band, the upper and lower sleeve pipe of steering column can not be changed by occurrence positions before assembling completes, and whole anti-rotation device dismounting is quick and convenient.
