There is inner cavity 2, and the left end of the first axle body 1 is fixedly connected with end 3 in a welding manner, the inside of end 3 is hollow structure, and
End 3 is internally provided with link block 4, and the left end surface of link block 4 is fixedly installed with shaft 5, and the outer surface package of shaft 5
There is lantern ring 6, the left end of lantern ring 6 is connected with pull ring 7, and the surface of pull ring 7 offers through-hole 8, and the left end surface of end 3 is symmetrically opened
Inside equipped with notch 9, and notch 9 is interspersed with the fixed link 10 being applied in inside through-hole 8, and the outer surface of fixed link 10 is solid
Surely it is connected with spring 11；
Connecting rod 12 is located at the inside of inner cavity 2, and the left end of connecting rod 12 is fixedly connected with link block 4, connecting rod 12
Right end is fixedly connected with the inner panel 13 being welded on 1 inner wall of the first axle body, and the right end face of inner panel 13 is fixedly connected with screw thread
Bar 14, the central point of threaded rod 14 and the central point of inner panel 13 are located in same horizontal line, and the second axle body 15 is in threaded rod 14
Upper is slide construction, and 14 central point of threaded rod and 13 central point of inner panel are located in same horizontal line, may insure threaded rod in this way
14 the second axle bodies 15 for being connected are consistent with 1 central point of the first axle body, and the right end of threaded rod 14 is threaded with the second axle body 15,
And second the surface of axle body 15 open up hole 16, the outer surface of the second axle body 15 is in thread-like structure, and the second axle body 15 exists
It is rotational structure on first axle body 1, helicitic texture and its rotation on the first axle body 1 by 15 surface of the second axle body can
To adjust the connection length of the two, the right end of the second axle body 15 is welded with end tail 17, and the right end face of tail 17 is held to be fixedly connected
There is impact block 18, hold the trapezoidal structure of longitudal section of tail 17, and the cross sectional dimensions on 17 left end surface of tail is held to be greater than the first axle body 1
Right end cross sectional dimensions, end tail 17 can prevent from carrying it into during 15 sliding extension of the second axle body by self structure
Into inner cavity 2.
If the connection type of pull ring 7 and lantern ring 6 is to weld, and pull ring 7 is rotational structure on shaft 5 in Fig. 1 and Fig. 3,
And pull ring 7 is symmetrically set with 2 about end 3, by pulling pull ring 7, assists convenient for user in no tool
In the case of, by dismounting hinge pin.
Such as the upper surface rectangular-blocklike projective structure of fixed link 10 in Fig. 3, Fig. 4 and Fig. 5, and fixed link 10 is in notch 9
Upper is slide construction, and the diameter dimension of fixed link 10 is identical with the diameter dimension of through-hole 8, by the way that fixed link 10 to be inserted into
In through-hole 8, limit can be fixed to pull ring 7, prevent it from influencing the normal operating of pin shaft.
Working principle: it in pin shaft dedicated using the agricultural harvester, needs according to the actual situation first, in the first axle body
The second axle body 15 is rotated on 1, since 15 surface of the second axle body has helicitic texture, and the second axle body 15 connects with threaded rod 14 again
It connects, so the second axle body 15 can be slided on the first axle body 1, thus convenient for users to changing the connection length of the two, and
If user needs the dismounting hinge pin that will be fixed, the impact block 18 on end tail 17 can be hammered by tool hammer, if do not had
There is tool hammer, user can be by stirring the projective structure in fixed link 10, so that fixed link 10 slides extruding on notch 9
Spring 11, so that no longer pull ring 7 be fixed away from through-hole 8, user's extruding at this time can be by lantern ring 6 in axis
Pull ring 7 is rotated on bar 5 keeps it vertical, then pulls pull ring 7, since pull ring 7 and link block 4 connect, while link block 4 further through
Connecting rod 12 and the inner panel 13 being welded on 1 inner wall of the first axle body connect, so user pulls pull ring 7 that can pull first
Axle body 1, so that dismounting hinge pin here it is the whole process that the dedicated pin shaft of the agricultural harvester uses, not made in this specification
