As depicted in figs. 1 and 2, a kind of bearing pin quick change mechanism of the utility model, comprise the first bearing pin 1, the second bearing pin 2, pin sleeve 3, sliding handle 4 and position limit pin 5, on described the first bearing pin 1, have tapped hole 6, one end end face of described the second bearing pin 2 has deep hole 7, on the wall of described deep hole 7, have a waist-shaped hole 8, on the wall of the deep hole 7 of described the second bearing pin 2, also have a spacing hole 9, described spacing hole 9 is positioned at same level straight line with described waist-shaped hole 8, is provided with the first spiral chute 10 and the second spiral chute 11 on described pin sleeve 3.
One end that described the first bearing pin 1 has tapped hole 6 is set in the inside, one end of pin sleeve 3, one end that described the second bearing pin 2 has deep hole 7 is set in the other end inside of pin sleeve 3, make the first bearing pin 1 part be arranged in the deep hole 7 of the second bearing pin 2, and the tapped hole 6 on described the first bearing pin 1 is corresponding with the position of waist-shaped hole 8 on the second bearing pin 2 and the first spiral chute 10 on pin sleeve 3, described sliding handle 4 is successively through being fixed in the tapped hole 6 of the first bearing pin 1 after the first spiral chute 10 on pin sleeve 3, the waist-shaped hole 8 on the second bearing pin 2.
Spacing hole 9 on described the second bearing pin 2 is corresponding with the position of the second spiral chute 11 on pin sleeve 3, after the second spiral chute 11 that described position limit pin 5 passes on pin sleeve 3, is fixed in the spacing hole 9 on the second bearing pin 2.
Between at the bottom of the hole of the deep hole 7 of described the first bearing pin 1 and described the second bearing pin 2, be provided with spring 12.
Embodiment one
When bearing pin is installed, the one end that the first bearing pin 1 is had to tapped hole 6 packs pin sleeve into from one end of pin sleeve 3, the one end that the second bearing pin 2 is had to deep hole 7 packs pin sleeve into from the other end of pin sleeve 3, now the part of the first bearing pin 1 is deep in the deep hole 7 of the second bearing pin 2, adjust the first bearing pin 1 and the second bearing pin 2, make the waist-shaped hole 8 arranging on the tapped hole 6 that arranges on the first bearing pin and the second bearing pin 2, and the first spiral chute 10 arranging on pin sleeve 3 be centered close to same axis, the second spiral chute 11 arranging on the spacing hole 9 arranging on the second bearing pin 2 and pin sleeve 3 be centered close to same axis.
Then sliding handle 4 is fixed in the tapped hole 6 arranging on the first bearing pin 1 after the waist-shaped hole 8 through setting on the first spiral chute 10 arranging on pin sleeve 3 and the second bearing pin 2 successively, after position limit pin 5 passes the second spiral chute 11 arranging on pin sleeve 3, is fixed in the spacing hole 9 on the second bearing pin 2.
