Description of drawings
Fig. 1 is the connecting device structural representation of column jecket branch unit and upper bracket in the prior art;
Upper bracket structural representation in the column jecket branch unit that Fig. 2 provides for the utility model embodiment and the connecting device of upper bracket;
The column jecket branch unit that Fig. 3 provides for the utility model embodiment and the connecting device structural representation of upper bracket;
Fig. 4 is the structural representation of handle assembly.
The specific embodiment
The column jecket branch unit that upper bracket structural representation in the column jecket branch unit that Fig. 2 provides for the utility model embodiment and the connecting device of upper bracket, Fig. 3 provide for the utility model embodiment and the connecting device structural representation of upper bracket.
As shown in Figures 2 and 3, the utility model embodiment provides the connecting device of a kind of column jecket branch unit and upper bracket, comprise column jecket branch unit and upper bracket 1, wherein, the column jecket branch unit is comprised of column jecket 22 and the lower bracket 21 that is welded on column jecket 22 outside wall surface, lower bracket 21 is the blanked part of symmetrical structure, is symmetrically arranged with the first connecting bore and the second connecting bore on it.
During handle assembly 4 locking, handle assembly 4 and clamp nut 3 combineds action are the side plates 12 that splayed arranges with two of upper bracket 1 and inwardly compress, and whole Steering gear is tightening state at this moment.When Steering gear and car load assemble, release handle assembly 4, act on the earth pressure release on the side plate 12, side plate 12 elastic recoils discharge the gap between upper bracket 1 and lower bracket 21, thereby when carrying out the Steering gear degree of depth or height adjustment, lower bracket 21 is along with column jecket 22 swings, can the not scratch internal face of upper bracket side plate 12 makes between upper bracket 1 and the lower bracket 21 can not interfere, and has improved assembly quality.
