The structural representation of the axis pin base provided.
In a kind of specific embodiment, as shown in Figure 1, Figure 2 with shown in Fig. 6, a kind of bearing pin that the present invention provides connects assembly,
Including bearing pin 1 and bearing pin pedestal 2, it is characterized by, bearing pin pedestal 2 is provided with the pin shaft hole 21 for installing the bearing pin adapted,
Pin shaft hole 21 is provided with the cylinder 11 of bearing pin 1.Further, one end of pin shaft hole 21 is provided with thread segment 1, thread segment
The other end of 1 is provided with circular hole 25, is provided with conical ring hole 1, thread segment 1 and circle between pin shaft hole 21 and thread segment 1
Conical ring hole 2 24 it is provided with between hole 25；One end of cylinder 11 is provided with thread segment 2 13, and the other end of thread segment 2 13 is provided with pin
Spindle nose 15, is provided with changeover portion 1, was provided with between thread segment 2 13 and bearing pin head 15 between cylinder 11 and thread segment 2 13
The section of crossing 2 14.Wherein, thread segment 1 and thread segment 2 13 are the screw thread being mutually paired.So, this bearing pin connection group is not only made
Part reaches default purpose, and is easy to processing.
During work, as it is shown in figure 1, be provided with the bearing pin 1 adapted with it on axis pin base 2, by the cylinder 11 of bearing pin 1
Parts 3 are positioned.Further, shown in Fig. 2 and Fig. 6, mid portion on cylinder 11 or away from screw thread
One end of section 2 13 is for installation targets parts 3, and thread segment 2 13 is arranged in thread segment 1, and the bearing pin head of correspondence
15 are also loaded onto in circular hole 25.It is apparent that this structure may be used on lid and the pedestal of docking, now, lid and pedestal are respectively pin
