Coordinate with opening, drive rod can be convenient for push push rod, so that the installation of bolt is more convenient.
The utility model is further arranged to, and the cross section of the push rod is T-shaped.
Using the above structure, it can prevent lockable mechanism from deviating from out of open slot and influence the installation of bolt.
The utility model is further arranged to, and the bolt head is equipped with capping, and the capping is fixed by pin and phase
It is rotatable to bolt head.
Using the above structure, capping can prevent dust and aqueous solution from entering circular hole and leading to drive rod and locking machine
Structure damages, to increase its service life.
The utility model is further arranged to, and the bolt head is equipped with the fixture block for fixed capping, the fixture block with
Capping interference fit.
Using the above structure, capping can be fixed, prevents from covering arbitrarily rotation and aqueous solution is caused to enter circle with dust
Hole, and influence the use of bolt.
The beneficial effects of the utility model：Compared to existing bolt, the utility model it is simple in structure it is novel, easy to operate,
It is connected firmly with anti-theft effect.The utility model can effectively prevent valve, equipment to be stolen phenomenon, ensure that oil field is normally given birth to
Production, improves oilfield economic benefit and field management is horizontal, avoids into oil, gas and water energy leakage, and environmental protection mitigates post work
The labor intensity of people.
