It states card inside ring-shaped groove and is placed with sealing shroud, the sealing shroud includes body of rubber, and the body of rubber both ends are provided with cavity,
The cavity inside is embedded with metal hose clamp, and bellows segment is provided among the body of rubber, and the bellows segment is internally provided with
Memory metal core wire.
Further, the horizontal distance between the ring-shaped groove is less than the length of sealing shroud.
Further, the body of rubber is made of NBR nitrile rubber.
Further, several seal convexities are provided on the body of rubber inner wall, the seal convexity cross section is
Trapezium structure.
Compared with prior art, the utility model has the beneficial effects that
The utility model can effectively separate geological prospecting by the way that sealing shroud is arranged between two plugs of universal shaft
Drilling tool intraclast in journey reduces the loss of articulated joint for screw drilling rod, improves the leakproofness at articulated joint for screw drilling rod position, improves
The service life of universal shaft, the sealing shroud with hose clamp is quick and easy for installation, and internal bellows segment design reduces universal shaft bending
Caused by wear, be worthy to be popularized.
