The bottom surface of pressing plate is bonded with the top surface of the cylinder block, also, is equipped between the pressing plate and the cylinder block by described in
The locking member of pressing plate locking.
As a further improvement, it is clearance fit between the pressure head and the oil hole.
Further, the pressure head and the sealing are equipped with gap between blocking.
Further, the pressing plate is equipped with the blind hole for installing the pressure head.
Further, it is interference fit between the pressure head and the blind hole.
Further, the locking member is clamping screw.
Further, the locking member quantity is at least 1.
A kind of sealing of engine blocks means of defence, and this method is that square cylinder block top surface increase will be close beyond the Great Wall in seal plug
Protective device of the closure plug closure in cylinder block.
As a further improvement, the protective device include pressing plate above the cylinder block and with the pressing plate phase
The pressure head for blocking and pinning will be sealed by connecting and being plugged in the oil hole of the cylinder block.
Beneficial effect
Compared with prior art, the present invention have the advantage that for：
1st, pin sealing using pressure head to block, recycle pressing plate that pressure head is fixed in cylinder block, can effectively prevent close
Closure plug comes off, and ensures the normal operation of engine lubrication system, makes more safe and reliable in engine working process；
2nd, pressure head and oil hole clearance fit and pressure head and sealing are equipped with gap between blocking can make simple installation of the present invention,
Also, it can guarantee that pressing plate is contacted with the fitting of oil hole plane, improve the stability of pressing plate locking；
3rd, pressing plate covers oil hole, can effectively prevent dust and enters oil hole；
4th, the configuration of the present invention is simple, production cost is low, there is good application value.
