The purpose of this utility model is achieved through the following technical solutions:
A kind of standard knot connects uses pivot pin component, comprise stub axle 1, it is characterized in that: described stub axle 1 is provided with dismountable sleeve 2, described stub axle 1 and sleeve 2 are provided with at least one first pin-and-hole 3, described first pin-and-hole 3 is all through the center of circle of stub axle 1 and sleeve 2, described stub axle 1 front end is provided with the second pin-and-hole 4, described first pin-and-hole 3 is provided with dismountable spring pin 5, described spring pin 5 runs through the first pin-and-hole 3 on stub axle 1 and sleeve 2, sleeve 2 is fixed on stub axle 1, described second pin-and-hole 4 is provided with dismountable bearing pin 6, described bearing pin 6 runs through the second pin-and-hole 4.
Described stub axle 1 rear end is provided with axle cap 7, and described axle cap 7 diameter is greater than the diameter of stub axle 1.
Described stub axle 1 front end, the first pin-and-hole 3, bearing pin 6 front end are provided with chamfering.
Described bearing pin 6 is provided with spring clamp 8.
Described spring pin 5 is hollow lateral open cylinder.
The technological scheme provided as can be seen from above-mentioned the utility model, the standard knot connection pivot pin component that the utility model embodiment provides, mount and dismount efficient and convenient, when saving as link fixed standard, safe and reliable, adopt the mode of spring pin and bearing pin dual fail-safe to fix, reduce unexpected generation.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection domain of the present utility model.
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment one
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: the standard knot of the present embodiment connects uses pivot pin component, comprise stub axle 1, described stub axle 1 is provided with dismountable sleeve 2, described stub axle 1 and sleeve 2 are provided with at least one first pin-and-hole 3, this example is two, one also can, more how good, but from cost and rational in infrastructurely to consider on both side, two the bests.Described first pin-and-hole 3 is all through the center of circle of stub axle 1 and sleeve 2, described stub axle 1 front end is provided with the second pin-and-hole 4, described first pin-and-hole 3 is provided with dismountable spring pin 5, described spring pin 5 runs through the first pin-and-hole 3 on stub axle 1 and sleeve 2, sleeve 2 is fixed on stub axle 1, described second pin-and-hole 4 is provided with dismountable bearing pin 6, and described bearing pin 6 runs through the second pin-and-hole 4.
As the further improvement of technique scheme, described stub axle 1 rear end is provided with axle cap 7, and described axle cap 7 diameter is greater than the diameter of stub axle 1.
As the further improvement of technique scheme, described stub axle 1 front end, the first pin-and-hole 3, bearing pin 6 front end are provided with chamfering.
As the further improvement of technique scheme, described bearing pin 6 is provided with spring clamp 8.
As the further improvement of technique scheme, described spring pin 5 is hollow circular cylinder, and described spring pin 5 is elastic material.
During use, this standard knot is dropped on the vertical direction of another standard knot, standard knot joint is provided with attachment hole, by the stub axle 1 of this pivot pin component through attachment hole, then upper bush 2 is overlapped, the first pin-and-hole 3 on stub axle 1 and sleeve 2 is on same straight line, then spring pin 5 is inserted, thus secure sleeve 2, sleeve 2 and axle cap 7 achieve the fixing of standard knot, again bearing pin 6 is passed the second pin-and-hole 4 simultaneously, bearing pin 6 is provided with spring clamp 8, dropping of pivot pin 6 can be stopped, thus further prevent the landing of sleeve 2, spring pin 5 and bearing pin 6 achieve dual fail-safe and fix.
When needs are by this pivot pin component removal, spring pin 5 ejected, then the spring clamp 8 on bearing pin 6 is pressed, bearing pin 6 is taken off from the second pin-and-hole 4, then takes off sleeve 2, stub axle 1 is taken down, thus realize the dismounting of pivot pin component.
