Embodiment two
The present embodiment is on the basis of the above embodiments, to optimize to eccentric bolt component.
As shown in Figure 1 to Figure 3, in the prior art, adjustment tank 14 is opened up on screw rod 1.It is corresponding, in eccentric washer 3
Eccentric orfice 31 is opened up, the inner wall of eccentric orfice 31 is equipped with an adjustment protrusion 32, which can be contained in adjustment tank 14.
In assembling process, eccentric washer 3 is held, after adjustment protrusion 32 is aligned with adjustment tank 14, screw rod 1 penetrates bias
Hole 31, so that adjustment protrusion 32 is located in adjustment tank 14 and can slide in the axial direction in adjustment tank 14.
Due in the prior art, being provided only with adjustment protrusion 32 in eccentric washer 3, in operation, screw rod 1 by
External force rotation, and apply the rotating torque of the same direction to eccentric washer 3.The rotating torque that screw rod 1 applies eccentric washer 3 is complete
Portion concentrates in adjustment protrusion 32, causes adjustment protrusion 32 to be easier to deform even and is broken, and adjusts protrusion 32 and can also
Deviate from out of adjustment tank 14, and then scratches the screw thread on 1 surface of screw rod.
For the defects in the prior art, the present embodiment improves eccentric bolt component:
The structural schematic diagram of eccentric washer, Fig. 9 are in the eccentric bolt component that Fig. 8 provides for the utility model embodiment two
Eccentric washer is assembled to the structural schematic diagram of screw rod in the eccentric bolt component that the utility model embodiment two provides.Such as Fig. 4, figure
7, shown in Fig. 9, adjustment tank 14 is opened up in the second end (end i.e. far from head 11) of bar portion 12, adjustment tank 14 is along bar portion 12
Axis direction extends.The quantity of adjustment tank 14 is two.
It is corresponding, as shown in figure 8, the eccentric orfice 31 passed through for bar portion 12 is opened up in eccentric washer 3, eccentric orfice 31
Inner wall is set there are two adjustment protrusion 32, and adjustment protrusion 32 can be contained in adjustment tank 14.One adjustment protrusion 32 and an adjustment
The position of slot 14 is corresponding, so that two adjustment protrusions 32 are respectively contained in an adjustment tank 14.
In assembling process, eccentric washer 3 is held, two adjustment protrusions 32 are aligned with corresponding adjustment tank 14 respectively
Afterwards, screw rod 1 penetrates eccentric orfice 31, so that two adjustment protrusions 32 are each located in corresponding adjustment tank 14 and can be in adjustment tank 14
Inside slide in the axial direction.
In operation, screw rod 1 is rotated by external force, and applies the rotating torque of the same direction to eccentric washer 3.Screw rod
The rotating torque that 1 pair of eccentric washer 3 applies is split in two adjustment protrusions 32, is reduced suffered by each adjustment protrusion 32
Power so that adjustment protrusion 32 be less likely to occur deform or be broken, be also not easy to deviate from out of adjustment tank 14, thus to screw rod 1
The screw thread on surface is protected.
Technical solution provided in this embodiment, the first end outer circumference surface in the bar portion of screw rod close to head are provided with flower
Key, adjustment gasket are set in spline periphery and are interference fitted with spline, and eccentric washer is set in second far from head in bar portion
End, above-mentioned screw rod and adjustment gasket are independent two components, are assembled together, are solved existing by way of interference fit
Process in technology for manufacturing screw rod with adjusting cold heading technique used by gasket is more complicated and to screw rod and adjustment gasket
The mode positioned is more difficult and the higher problem of technique manufacturing cost, and the screw rod and adjustment gasket in the present embodiment can
To be respectively prepared, such as: using modes such as casting, forgings, one side manufacturing process is relatively simple, improves manufacture efficiency；Separately
On the one hand without being positioned in the fabrication process, manufacturing process is simplified；In another aspect, when one of bar or adjustment gasket need
When replacement, one of them is only replaced, is replaced together without two, manufacture and maintenance cost are reduced.In addition, the of bar portion
Two ends open up two adjustment tanks, and the corresponding eccentric hole wall in eccentric washer opens up two adjustment protrusions, and an adjustment protrusion is corresponding
It is contained in an adjustment tank, so that screw rod is split in two adjustment protrusions the rotating torque that eccentric washer applies, reduces
Power suffered by each adjustment protrusion is also not easy so that adjustment protrusion 3 is less likely to occur to deform or be broken from adjustment tank
The screw thread of screw surface is protected in interior abjection, realization.
