Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The utility model discloses an embodiment relates to a length-adjustable steering column, as shown in fig. 1-3, including jackshaft 1, the both ends of jackshaft 1 install fixed universal joint 2 and movable universal joint 4 respectively, the one end axial of jackshaft 1 be connected with one and

insert post

3, 4 tip of movable universal joint be equipped with and supply to insert post 3 male jack 8, the lateral wall of 4 tip of movable universal joint on be provided with a word cut-out 5, with the adjusting bolt 6 of 5 plane looks vertically screw holes of a word cut-out and this screw hole of screw in, adjusting bolt 6 on the cover have packing ring 9, a word cut-out 5 and jack 8 intercommunication.

Two pulling grooves 7 are symmetrically arranged on the two sides of the straight-line-shaped opening 5 of the side wall of the end part of the movable universal joint 4, and the end part of the movable universal joint 4 can be pulled manually through the pulling grooves 7, so that the straight-line-shaped opening 5 is widened.

Four planes 10 are uniformly arranged around the outer side of the inserted column 3, and the insertion hole 8 is in a square hole shape. The flats 10 engage the walls of the socket 8 bore instead of a splined engagement.

The shape of the jack 8 is one of square, rectangle and rhombus, and the jack 8 and the plug post 3 can not rotate relatively as long as the jack and the plug post are installed.

The horizontal section 5 is adjusted to be widened or narrowed by rotating the adjusting bolt 6, so that the jack 8 at the end part of the movable universal joint 4 and the inserted column 3 of the intermediate shaft 1 are loosened or clamped, and the left and right relative positions between the intermediate shaft 1 and the movable universal joint 4 are adjusted.
