Described positioning key is multiple flat key or spline.
The eccentric adjusting section of described eccentric shaft end is that hexagon prism imitates nut structure.
Described bearing is self-lubricating bearing or ball bearing.
Described ratchet and end cap are structure as a whole.
Beneficial effect: the present invention is compared with traditional eccentric adjuster, after a whole set of self-locking adjustable eccentric guider is installed, use the hexagon post of spanner rotating eccentricity axle head, eccentric wheel can be regulated under stressed state, do not need fixing in addition after adjustment completes, realize locating by the self-locking of ratchet and ratchet, decrease the workload of site installation test, and can when stressed Secondary Control, very practical.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation of the present invention.
The present invention includes eccentric shaft 1, end cap 2, travel(l)ing rest 3, guide wheel 4, bearing 5, fixed support 6, ratchet 7, ratchet 8 and positioning key 9.
Described eccentric shaft 1 is five sections of hierarchic structures, successively respectively mounting and fixing bracket 6, in establish the guide wheel 4 of bearing 5, travel(l)ing rest 3, ratchet 8 and end cap 2.
Guide wheel 4 is contained in eccentric shaft 1 middle part, and bearing 5 is housed between guide wheel 4 and eccentric shaft 1, and this bearing 5 can be the type such as self-lubricating bearing or ball bearing.
Figure 2 shows that A-A of the present invention internally structural representation.
Described ratchet 8 is located between end cap 2 and travel(l)ing rest 3, to be coordinated with eccentric shaft 1 by positioning key 9 and install, relatively rotating between positioning key 9 fixed ratchet wheel 8 and eccentric shaft 1, while eccentric shaft 1 rotates, ratchet 8 also rotates together, the quantity of positioning key 9 can be multiple flat key, also can be spline joint.
Described ratchet 7 is fixedly mounted on end cap 2, also ratchet 7 and end cap 2 can be made into a global facility, end cap 2 is bolted on travel(l)ing rest 3 side, when eccentric shaft 1 rotates, end cap 2 does not move, ratchet 7 can not relative motion inside end cap 2, when eccentric shaft 1 is by side force, due to the self-locking relation of ratchet 8 and ratchet 7, ratchet 8 can not counter motion, therefore eccentric shaft 1 can not rotate, and guide wheel 4 can only relatively rotate in the position regulated, and can not move horizontally.
Figure 3 shows that the structural representation of eccentric shaft of the present invention.
The end of described eccentric shaft 1 is eccentric adjusting section, has coordinated the adjustment to eccentric guider with instrument.
Described eccentric shaft 1 is with fixed support 6 and travel(l)ing rest 3 is coaxial, with the axis being parallel of guide wheel 4 and its spacing is a.
The eccentric adjusting section of described eccentric shaft 1 end is that hexagon prism imitates nut structure.Rotate hexagon prism part, hexagon prism imitates nut structure design, and available standards spanner rotates.
First eccentric shaft 1 is arranged on fixed support 6 during installation, then bearing 5 and guide wheel 4 is assembled, be installed to together on eccentric shaft 1, buckle travel(l)ing rest 3; Then together with ratchet 8 being installed to positioning key 9, then be installed on travel(l)ing rest 3; Be installed on travel(l)ing rest 3 together with ratchet 7 is fixed with end cap 2, the position of ratchet 7 during installation, should be well placed, make ratchet 7 flexible with ratchet 8 positive movement, counter motion self-locking.
After installation of the present invention, the end eccentric adjusting section of eccentric rotation axis 1, ratchet 8 is rotated along forward (non-self-lock-ing direction), the relative position of adjustable support axis and guide wheel 4 axis, after eccentric shaft 1 is adjusted to the right place, ratchet 7 can automatically by locked for ratchet 8, and this device eccentric adjusting completes.
Because ratchet 7 and ratchet 8 allow one-way movement, so spanner can be used to regulate guide wheel 4 relative to the distance between travel(l)ing rest 3 by rotation eccentric axis 1.The axis of guide wheel 4 and eccentric shaft 1 are a with the connecting axle distance between centers of tracks of travel(l)ing rest 3, then the adjustable scope of 4 guide wheel is ± a.Because ratchet 7 and 8, ratchet allow one-way movement, self-locking in the other direction, because ratchet 7 is fixed on end cap 2, ratchet can not relative motion inside end cap, when eccentric shaft is by side force, due to the self-locking relation of ratchet and pawl, ratchet can not counter motion, therefore eccentric shaft can not rotate, even if so guide wheel 4 is subject to larger horizontal force, also can not change the relative position regulated.
In Fig. 2 self-locking adjustable eccentric guider be guide wheel 4 minimum eccentric time effect, after rotation eccentric axis 1 to 180 is spent, guide wheel 4 is maximum eccentric, and Figure 4 shows that the effect schematic diagram of the maximum outer eccentric embodiment of the present invention, both regulated quantitys have changed 2a.
The present invention is compared with traditional eccentric adjuster, after a whole set of self-locking adjustable eccentric guider is installed, use the hexagon post of spanner rotating eccentricity axle head, eccentric wheel can be regulated under stressed state, do not need fixing in addition after adjustment completes, realize locating by the self-locking of ratchet and ratchet, decrease the workload of site installation test, and can when stressed Secondary Control, very practical.
The above-mentioned embodiment of the present invention, just illustrates, is not only, and the change within the scope of the present invention all or equivalent scope of the present invention is all surrounded by the present invention.
