Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
Embodiment 1, as shown in fig. 1 and 4, comprises a tie rod holder 6 and a steering bracket 5, both of which are attached to the frame of the trolley, wherein the tie rod holder 6 is located above.
The steering column comprises a steering bracket 5, a connecting part 11, a main body part 12 and a base part 13, wherein the top end of the connecting part 11 is provided with a spline for connecting a steering wheel, the main body part 12 is hinged with the pull rod fixing seat 6, and the connecting part 13 is hinged with the steering bracket 5.
Two extending pieces 51 are arranged on the steering bracket 5, the two extending pieces 51 extend to the pipe column assembly 1, and each extending piece 51 is provided with a connecting hole 52. A hinge tube 131 is provided at the base part 13 at the lower end of the column assembly 1, and a user passes through the connection hole 52 using the pin 7 to be connected with the hinge tube 131. The column assembly 1 and the steering bracket 5 rotate relatively by taking the pin shaft 7 as an axis, namely the point O in fig. 4.
In the transmission process, in order to further improve the rotation stability, as shown in fig. 3, at least one extension piece 51 is provided with a kidney-shaped adjusting groove 511, a positioning through hole 132 is provided in the base portion 13, and a positioning member 133, such as a positioning bolt, is connected to the positioning through hole 132 through the kidney-shaped adjusting groove 511, and when the two components rotate, the positioning member 133 slides in the kidney-shaped adjusting groove 511. The kidney-shaped adjustment groove 511 not only provides guiding stability, but also limits the rotation trajectory.
The following describes the position structure of another hinge point, i.e. the Q point in fig. 4. As shown in fig. 1, the adjusting lever 3 includes a straight sliding portion 31 and a curved rotating portion 32 at a lower position, and the end of the curved rotating portion 32 is movably connected with the lever fixing seat 6 by a pin or the like.
Accordingly, the whole pipe column assembly 1 can be turned over at a certain angle on the vertical surface, and the pipe column assembly 1 and the adjusting pull rod 3 rotate respectively through O and Q in FIG. 4 as fulcrums.
The function of the adjusting pull rod 3 is to cooperate with the locking device 2 to fix the angle of the tubular column assembly 1, i.e. the steering wheel. Specifically, as shown in fig. 2, a fixing piece 21 is provided on the pipe column assembly 1, and the fixing piece 21 abuts against the slide lock block 4. The slide lock block 4 is provided with a slide hole 42 through which the flat slide portion 31 passes. The slide lock block 42 further comprises two clips 41, and each clip 41 is provided with a through hole 44, and the locking bolt 22 passes through the fixing piece 21 and through the two clips 41. The locking handle 23 is internally threaded and is connected to the locking bolt 22.
When a user turns over the tubular column assembly 1 to adjust the angle of the steering wheel, the pull rod 3 is synchronously turned over, and the sliding lock block 4 and the pull rod 3 slide relatively. When the angle is adjusted in place, the user only needs to operate the locking handle 23 to screw, and the two clamping pieces 41 are clamped and fixed by the fixing piece 21 and the locking handle 23 one by one, so that the clamping is contracted. At this time, the aperture of the sliding hole 42 is reduced, so that the adjusting bar 3 is tightly clamped, the sliding lock block 4 and the adjusting bar 3 do not slide relatively, and the steering wheel angle is locked.
