Locking pin includes pin ontology, the support element positioned at pin body bottom portion and the plug that is connected with pin ontology one end, pin
Ontology includes symmetrically arranged two arc-shaped mounting grooves, and mounting groove is through the top of pin ontology and the bottom of pin ontology
Portion, and two bolt protection cases are respectively sleeved in two mounting grooves, the bottom end of bolt protection case offers to be arranged bolt
Bolt mounting holes.
Preferably, pin ontology is connected with being integrated of plug so that manufacture is more convenient.
Preferably, the material of support element is stainless steel, and the material of pin ontology is structural alloy steel so that from locking tool
With higher intensity and toughness.
Preferably, bolt protection case top be equipped with Hexagon hole so that can with allen wrench easy to use carry out for
The dismounting of bolt protection case.
The beneficial effects of the utility model are：By the way that adjacent two being arranged on the auxiliary plate of wheel hub blade bolt is arranged
In bolt protection case, and then the thread of blade bolt is protected not to be damaged, and the plug of blade locking pin is inserted in wheel hub pin
Kong Zhong, and two bolt protection cases are respectively sleeved in two mounting grooves of blade locking pin, so as to fulfill make the auxiliary plate of wheel hub with
Wheel hub achievees the effect that lock blade without relative motion.And this blade locking tool is independently of unit, latched position is more clever
It is living, can according to staff need be locked to any position, when occur impeller safeguard, replace component or other operating modes when,
If the original blade locking arrangement of unit can not meet, you can use the tooling.
