Claims

[Scope of utility model registration request]

A partition 2 having a through hole 3 in the center and an engaging protrusion 4 protruding from a part of the inner periphery of the through hole 3 is formed in the middle of the interior, and furthermore, a support arm 5 is protruded laterally from the outside. At one side opening of the connecting tube 1 installed,
A bolt 6 having an axial engagement groove 7 provided on the outside of the spiral portion 6a is rotatably coupled, and the connecting end of one connecting rod a with the spiral portion 6a protruding from the tip is inserted into the bolt 6. The engagement protrusion 4 is fitted into the concave groove 7 of the spiral portion 6a, and the through hole 3 is inserted, and the bolt 6 is inserted into the connection end surface of the other connection rod to be connected.
A screw hole 8 is provided to be screwed into the connecting tube 1, and this is inserted into the opening on the other side of the connecting tube 1, and the bolt 6 is tightened by the rotation of the connecting tube 1 through the engagement between the engaging protrusion 4 and the recess i6a. The bolt 6 and the threaded hole 8 are screwed together by rotating the bolt 6, and the engaging protrusion 4 is formed to have a strength that automatically breaks when the rotational torque of the bolt 6 reaches a predetermined maximum value. A screw connection device for pipe materials.
