Explanation is further explained to the utility model with reference to specific embodiment.
Pivot structure as shown in Figure 1, including die casting stent 1, bushing 2, bushing fixing piece 3, cableties 4, die-cast chassis 5,
Foot pad 6, hand lock screw 7 and hinge component 8.
Die-cast chassis 5 is provided with receiving portion 11 on die-cast chassis 5, is set on die casting stent 1 for fixing total
External part 10 is equipped with, in the prior art, passes through the receiving being inserted into the external part 10 on die casting stent 1 on die-cast chassis 5
In portion 11, so as to fixed die casting stent 1.Fixed die casting stent in this way, because being between die casting and die casting
Cooperation, easily generate gap, die casting stent can generate shaking, and product fraction defective is high, once generation is bad, wherein a die casting
Part will be scrapped.So in the utility model, between the external part 10 of die casting stent 1 and the receiving portion 11 of die-cast chassis 5
Setting is there are one bushing 2, and the material of the bushing is soft material, such as plastics, rubber.
As shown in figure 3, bush structure includes inner surface and outer surface, the external part 10 of die casting stent 1 and the interior table of bushing 2
Face fits closely, and the outer surface of bushing 2 is fitted closely with the receiving portion 11 on die-cast chassis 5, so as to which bushing 2 is pressed in die casting branch
Between the outer surface of the external part 10 of frame 1 and the receiving portion 11 of die-cast chassis 5, pressure is filled using the elasticity of the material of bushing 2
Cast the gap between the receiving portion of the die-cast chassis 5 of 1 external part 10 of stent.
As shown in Fig. 2, bushing 2 includes two planar walls being oppositely arranged and two curved walls being oppositely arranged, planar wall
It is adjacent with curved wall, location hole 9 is both provided on two planar walls being oppositely arranged, as shown in figure 5, die casting stent 1 is stretched
The outer surface of outlet 10 includes two planes being oppositely arranged and two curved surfaces being oppositely arranged, in the plane that two are oppositely arranged
On be both provided with location hole 17, bushing fixing piece 3 passes through positioning 9 and location hole 17 so that the stretching of bushing 2 and die casting stent 1
End 10 locks.The top and bottom of bushing 2 are opening form, and open-topped area is more than the area of bottom opening,
So that bushing 2 is set substantially in reverse frustoconic on two planar walls being oppositely arranged of bushing 2 close to open-topped place
