Abstract
The utility model discloses one kind to rotate column tube structure, provide a kind of simple in structure, it can effectively avoid, lower column tube relatively rotates, improve positioning accuracy, and absorbable impact energy, reduce the anti-rotation column tube structure of personal damage degree, solve steering column existing in the prior art easily to relatively rotate, the conveying of steering column needs to be equipped with material rack special, it is of high cost, the technical problem of time-consuming and laborious grade, it includes lower column tube and interworking is set with and is locked in the upper column tube of lower column tube upper end, with it is described on be equipped with axial slide on the corresponding lower column tube outer ring surface of column tube, upper column tube inner ring surface corresponding with axial slide is equipped with cambered surface axial direction raised line, cambered surface axial direction raised line interworking extends in axial slide and keeps being slidably connected.
Description
Technical field
A kind of rotation column tube structure is the utility model is related to, more particularly to one kind can effectively avoid opposite turn of upper and lower column tube
It is dynamic, positioning accuracy, and absorbable impact energy are improved, reduces the anti-rotation column tube structure of personal damage degree.
Background technology
When transporting and assembling steering column, many factories require that regulation handle is in locking state all the time, if
When upper and lower column tube relatively rotates because of ectocine, directly result in the upper and lower mount point of steering column and change, into
And influence assembling.Existing most common method of controlling is to carry out management and control to the packaging and logistics of steering column supplier, or
Person sets the material rack special of anti-collision in production line, time-consuming and laborious, adds production cost.
The content of the invention
The utility model mainly there is provided a kind of simple in structure, can effectively avoid upper and lower column tube and relatively rotates, it is fixed to improve
Position precision, and absorbable impact energy, reduce the anti-rotation column tube structure of personal damage degree, solve existing in the prior art
Steering column easily relatively rotates, and the conveying of steering column needs to be equipped with material rack special, of high cost, the technology of time-consuming and laborious grade
Problem.
The above-mentioned technical problem of the utility model is mainly what is be addressed by following technical proposals：A kind of anti-rotation column
Pipe structure, including lower column tube and interworking are set with and are locked in the upper column tube of lower column tube upper end, with it is described on column tube it is corresponding
Lower column tube outer ring surface be equipped with axial slide, upper column tube inner ring surface corresponding with axial slide is equipped with cambered surface axial direction raised line,
Cambered surface axial direction raised line interworking extends in axial slide and keeps being slidably connected.By being set between the mating surface of upper and lower column tube
The axial slide and cambered surface axial direction raised line of interworking, you can effectively avoid producing relative rotation between upper and lower column tube, cambered surface axis therein
It is simple in structure to raised line easy to import axial slide, it ensure that assembly precision, while once collide, the arc on upper column tube
Face axial direction raised line is slided along the axial slide on lower column tube, and then absorbs impact energy, the damage of personnel and the damage journey of device
Degree reduces minimum.
Preferably, with it is described on the opposite lower column tube bottom of column tube be equipped with mounting flange, set on mounting flange
There is lower opening slot.By setting lower opening slot to be used for the location and installation of lower column tube on the mounting flange of lower prop tube end.
Preferably, column tube overcoat passes through tune equipped with clamping lever, upper column tube is adjusted on corresponding with the lower column tube
Section clamping lever is fixedly clamped on lower column tube.It is fixedly clamped upper and lower column tube by adjusting clamping lever, simple in structure, installation
It is convenient.
As it is further preferred that corresponding adjust in column tube both sides is arranged with upper installing hole on clamping lever on described.Upper peace
Fill the location and installation that hole is used for upper column tube.
Therefore, a kind of anti-rotation column tube structure tool of the utility model has the advantage that：Pass through the cooperation in upper and lower column tube
The axial slide and cambered surface axial direction raised line of interworking are set between face, equivalent to key connection between upper and lower column tube, you can effectively avoid,
Produce relative rotation between lower column tube, it is simple in structure, it ensure that assembly precision, while once collide, the cambered surface on upper column tube
Axial raised line is slided along the axial slide on lower column tube, and then absorbs impact energy, the damage of personnel and the damaged in collision of device
Degree reduction is minimum, so as to ensure that the security of the lives and property.
Brief description of the drawings：
Fig. 1 is a kind of structure diagram of anti-rotation column tube structure of the utility model.
Embodiment：
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment：
As shown in Figure 1, a kind of anti-rotation column tube structure of the utility model, including lower column tube 1 and interworking are sleeved on lower prop
The upper column tube 2 of 1 upper end of pipe, is set with outside column tube 2 on corresponding with lower column tube 1 and adjusts clamping lever 7, upper column tube 2 passes through tune
Section clamping lever 7 is fixedly clamped on lower column tube 1, in the coaxial fixed Method for Installation in lower column tube 1 bottom opposite with upper column tube 2
Orchid 5, carries lower opening slot 6 on mounting flange 5, is symmetrically provided with and pacifies on the corresponding adjusting clamping lever 7 in upper 2 both sides of column tube
Hole 8 is filled, and the split of lower opening slot 6 is parallel with the shaft core line of upper installing hole 8, in lower 1 outer shroud of column tube corresponding with upper column tube 2
An axial slide 3 is provided with face, stretching out on upper 2 inner ring surface of column tube corresponding with axial slide 3, it is axially convex to form cambered surface
Bar 4,4 interworking of cambered surface axial direction raised line extend in axial slide 3 and keep being in axial sliding connection.
Specific embodiment described herein is only the design explanation for example to the utility model.The utility model
Person of ordinary skill in the field can do various modifications or additions or using class to described specific embodiment
As mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
