Abstract
The utility model discloses a steering pipe post provided with spring pins. The steering pipe post comprises an upper pipe body and a lower pipe body, wherein spring pin mechanisms are arranged on the lower pipe body, and positioning holes corresponding to the spring pin are formed in the upper pipe body. Preferably, each spring pin mechanism comprises a spring and a steel ball, and the diameter of the steel ball is equal to the diameter of the spring. Preferably, the number of the spring pin mechanisms is two or more than two. Preferably, the number of the positioning holes formed in the upper pipe body is two or more than two. The steering pipe post has the beneficial effects that the structure of the steering pipe post is simple, the reutilization can be realized, the service life is long, and the safety performance is good.
Description
Technical field
The utility model belongs to the vehicular spare parts field, particularly a kind of steering column that is provided with spring pin.
Background technology
Existing steering column structure comprises upper and lower two sections, and upper steering column is slightly thinner than lower steering column, can be enclosed within the endoporus of lower steering column, is pressed into the steel ball with plastic space ring between the two.Spacer ring plays ball retainer, and steel ball and upper and lower steering column compress and make it to combine.During collision, upper lower tubular column is at axial relative displacement, and at this moment the wall at upper and lower steering column extrudes groove to steel ball while rotating, thereby has consumed impact energy.
It is destructurized after collision for the steering column of this kind structure, can not reuse, and its poor safety performance, its service life for once, very waste.
The utility model content
For the deficiencies in the prior art, the utility model provides a kind of and reuses and steering column that safety performance is good.
To achieve these goals, the utility model is that the technical scheme that its technical matters of solution is taked is:
A kind of steering column that is provided with spring pin comprises upper tube body and lower tube body, and described lower tube body is provided with spring pin mechanism, and upper tube body is provided with knock hole corresponding to spring pin.
As preferably, described spring pin mechanism comprises spring and steel ball, and steel ball size equals spring diameter.
As preferably, described spring pin mechanism is two or more.
As preferably, the knock hole on the described upper tube body is two or more.
The beneficial effects of the utility model: the utlity model has simple in structurely, can again utilize, long service life, safety performance is good.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of steering column that is provided with spring pin as shown in Figure 1 comprises upper tube body 1 and lower tube body 2, and described lower tube body 2 is provided with spring pin mechanism 3, and upper tube body 1 is provided with knock hole corresponding to spring pin 4.Described spring pin mechanism 3 comprises spring 5 and steel ball 6, and steel ball 6 diameters equal spring 5 diameters.Described spring pin mechanism 3 is two or more.Knock hole 4 on the described upper tube body 1 is two or more.
When colliding, the utility model steering column firmly presses body by bearing circle, then upper tube body produces the application force to spring pin mechanism, make spring contraction, thereby consumed a part of application force, down sliding again, through second spring pin mechanism, consume again a part of application force, until all pressure of colliding are complete at spring pin mechanism internal consumption.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
Claims (4)
