Pinion gear 4 is engaged with gear wheel 5；
Gear wheel 5 and cam disc 2 are set in outside the second shaft 7, and gear wheel 5 is fixedly connected with cam disc 2, cam 3 with
Second shaft 7 is fixedly connected；
Uniform intervals are set there are two ramp 21 on cam disc 2, and uniform intervals set that there are two double wedges 31 on cam 3.
Specifically, first rotating shaft 6 passes through the center of rotation of handle 1 and pinion gear 4, and it is fixedly connected with.Stir handle 1
When, handle 1 is rotated centered on first rotating shaft 6；First rotating shaft 6 drives pinion gear 4 to rotate together after rotating.
The outer rim of pinion gear 4 is engaged with the outer rim of gear wheel 5.
Gear wheel 5 is set in the second shaft 7, does not drive the rotation of the second shaft 7 directly.But pass through 2 He of cam disc
Cam 3 is driven.Cam disc 2 is located in the inner ring of gear wheel 5.Gear wheel 5 is fixedly connected with cam disc 2, when gear wheel 5 rotates
Cam disc 2 is driven to rotate together, the double wedge 31 of the ramp 21 on cam disc 2 and cam 3 cooperates, and ramp 21 pushes cam 3
Double wedge 31 so that axial movement of the cam 3 along the second rotation axis 7, cam 3 and the second rotation axis 7 are fixed, drive the second rotation
Axis 7 is also axially moveable.It is clearance fit between second rotation axis 7 and cam disc 2.
In the present embodiment, it is driven by two shafts and two gears.Pinion gear and gear wheel are by adjusting transmission ratio
The angle that rotates is needed when opening or closing adjust handle 1, guarantees that handle work angle is constant or is adjusted to suitable angle
Degree.
Alternatively it is also possible to not need the work angle that gear set carrys out regulation handle, or pass through other transmission components
Carry out the work angle of regulation handle.
As shown in fig. 6-7, it on cam disc 2 there are two ramp 21, is spaced between two ramps 21 on cam disc 2
180°.There are two double wedge 31 on cam 3,180 ° are spaced between two double wedges 31 on cam 3.
Due to being set on cam disc 2 there are two ramp 21, compared to existing four ramps, the inclination angle of ramp 21
Degree slows down or becomes smaller.When double wedge 31 slides in ramp 21, the collision between double wedge 31 and ramp 21 is smaller, solves
The noise of the problem of hired roughneck, generation also reduce.
As shown in figures 3 and 8, when opening handle, handle 1 is stirred towards arrow downward in Fig. 3.Handle 1 drives the
One shaft 6 rotates clockwise, and first rotating shaft 6 drives pinion gear 4 to rotate clockwise, and pinion gear 4 drives gear wheel 5 to turn counterclockwise
Dynamic, gear wheel 5 drives cam disc 2 also to rotate counterclockwise, and the ramp 21 of cam disc 2 pushes the double wedge 31 of cam 3, so that double wedge
31 slide along ramp 21.When the handle is open, double wedge 31 slides into the minimum point of ramp 21.
When closing handle, handle 1 is stirred towards arrow upward in Fig. 3, handle 1 drives first rotating shaft 6 to turn counterclockwise
Dynamic, first rotating shaft 6 drives pinion gear 4 to rotate counterclockwise, and pinion gear 4 drives gear wheel 5 to rotate clockwise, and gear wheel 5 drives convex
Wheel disc 2 also rotates clockwise, and the ramp 21 of cam disc 2 pushes the double wedge 31 of cam 3, so that double wedge 31 is sliding along ramp 21
It is dynamic.When the handles are close, double wedge 31 slides into the highest point of ramp 21.
Further, as shown in Figure 4 and Figure 6, locating slot 51 is offered on a side end face of gear wheel 5, cam disc 2 is determined
Position protrusion 22, positioning protrusion 22 snaps onto locating slot 51.
The cooperation of positioning protrusion 22 and locating slot 51 is reached by the elastic bumps structure in 5 inner ring locating slot 51 of gear wheel
Cooperate to consolidation, so that cam disc 2 is fixed as one with gear wheel 5.
Further, as illustrated in figures 4-5, steering column clamping system further includes gear housing 8, and gear housing 8 is located at
Outside pinion gear 4 and gear wheel 5, first shaft hole 81 and the second axis hole (not shown) are offered in gear housing 8, first rotating shaft 6 is worn
First shaft hole 81 is crossed, the second shaft 7 passes through the second axis hole.
Be located in the cavity of the inner ring of gear wheel 5 due to cam disc 2, gear housing 8 by pinion gear 4, gear wheel 5,
Cam disc 2 and cam 3 are provide with inside it, and are anchored on the outer wall of bracket 9, and protection is played the role of.
It is located at the outside of gear housing 8 at the center of rotation of handle 1, first rotating shaft 6 sequentially passes through handle 1, gear housing 8
First shaft hole 81 and pinion gear 4.Second shaft 7 sequentially passes through the second axis hole, cam 3, cam disc 2, canine tooth of gear housing 8
Regulating tank 91 on wheel 5 and bracket 9.After handle 1 is opened, the second shaft 7 can be slided along regulating tank 91, for adjusting steering tube
The angle of column.
Further, as shown in figs 6-8, the cross section of double wedge 31 is sector, and the cross section of ramp 21 is also sector, tiltedly
The thickness of ramp 21 gradually changes from low to high；
When handle 1 is opened, double wedge 31 is moved to the highest point of ramp 21；
When handle 1 is closed, double wedge 31 is moved to the minimum point of ramp 21.
Further, as shown in fig. 6, the highest point of ramp 21 is equipped with retention bead 23, retention bead 23 is for limiting
Double wedge 31 crosses ramp 21.
The thickness of retention bead 23 is significantly greater than the thickness of the highest point of ramp 21, when double wedge 31 slides into ramp 21
Highest point at, be limited protrusion 23 stop, forward slip cannot be further continued for.Prevent double wedge 31 from crossing ramp 21 from ramp
It is fallen on 21, and the minimum point of ramp 21 cannot be returned to.
Preferably, the output angle of pinion gear 4 is 45 °, i.e. handle when the transmission ratio of pinion gear 4 and gear wheel 5 is 4:1
Work angle be 45 °.
Optionally, by adjusting the transmission ratio of pinion gear 4 and gear wheel 5, to adjust the output angle of pinion gear 4.Small tooth
The rotational angle when output angle of wheel 4 is opened or closed with handle 1 is identical.To finally play the angle of rotation of regulation handle 1
The effect of degree adjusts gear ratio according to the rotational angle demand of different user to realize.
Above-described is only the principles of the present invention and preferred embodiment.It should be pointed out that for the general of this field
For logical technical staff, on the basis of the utility model principle, several other modifications can also be made, also should be regarded as practical
Novel protection scope.
