Preferably, the madial wall of the upper end of described shank extends to form stop block to described cavity, and the lower end of described pin rod protrudes out first boss, and described stop block limits the slip of described first boss.
Preferably, described first boss has extended axially first round platform to described cavity, and the diameter of described first round platform is less than the diameter of described cavity, and described elastomeric upper end is set on described first round platform and with described first boss and conflicts.
Preferably, described combination pin also comprises back-up ring, and the fixing described pin tail of described back-up ring because described back-up ring is detachable, therefore can make described pin tail disassemble in described shank in described shank, and the elastomer in the described cavity is changed.
Preferably, offer concave surface and groove on the madial wall of the lower end of described shank, the upper end of described pin tail protrudes out second boss of conflicting with described concave surface, described back-up ring be arranged in the described groove and described second boss of fixed constraints in described concave surface.
Preferably, described second boss is the two stage steps structure, described two stage steps structure forms first step face and second step face, described first step face and described concave surface are conflicted, described second step has extended axially second round platform towards described cavity, the diameter of described second round platform is identical with the diameter of described first round platform, and described elastomeric lower end is set on described second round platform, and conflicts with described second step face.Alternatively, described second boss is the one-level ledge structure, described one-level ledge structure and described concave surface are conflicted, described one-level ledge structure has extended axially second round platform to described cavity, the diameter of described second round platform is identical with the diameter of described first round platform, described elastomeric lower end is sheathed on described second round platform, and conflicts with described one-level ledge structure.
Preferably, described elastomer is a helical spring, alternatively, also can be other elastomer.
Preferably, described pin rod and described pin tail all offer vent along central axis, and described vent runs through described pin rod and described pin tail and is communicated with described cavity.When described combination pin was applied in the vacuum cavity, vent was convenient to the air discharge in enclose inside space.
Preferably, the upper end of described pin rod is taper type.
Compared with prior art, because combination pin of the present utility model comprises pin rod, shank, pin tail and elastomer, described pin rod, shank, pin tail and elastomer are composite structure, when in use, the pin tail is fixed on the fixed plate, the registration holes that penetrates the carrier that is arranged in its top that pin rod then slides, therefore, described pin rod plays the effect of guiding and location to carrier; In addition, because described elastomer is conflicted and is connected between described pin rod and the described pin tail, therefore, thereby described pin rod can glide vertically under the action of gravity of carrier and compress described elastomer, described elastomer plays the effect of buffering to described pin rod, produces the bending distortion when avoiding described pin rod to be subjected to described carrier compressing, damages carrier or make vector form deforming.
