Protective cover for shoulder part of pressure vessel
The present invention relates to a protective cover for a shoulder part of a pressure vessel, and more particularly, to a protective cover coupled to a shoulder part of a pressure vessel to protect the shoulder part from friction or impact.
1 . A protective cover for a shoulder part of a pressure vessel, which is coupled to the shoulder part disposed on one or both sides of the pressure vessel to protect the shoulder part, the protective cover comprising:
an impact resistance member made of impact-absorbing foam;
an outer shell coupled to the impact resistance member and wrapping around the impact resistance member; and
a detachable means for detachably coupling the impact resistance member and the outer shell to each other, wherein the detachable means comprises:
a holding part, which has a fixing groove formed at a position spaced apart from an edge of the outer shell toward the center of the outer shell, and a push bar rotatably mounted on the outer shell to elastically press an outer surface of the impact resistance member or return the impact resistance member to an original position thereof; and
a fitting part, which protrudes outward from the outer surface of the impact resistance member and includes a coupling protrusion seated on the fixing groove.
2 . The protective cover according to claim 1 , further comprising a slit formed between the outer surface of the outer shell, wherein the push bar comprises a bridge connecting the push bar and the outer shell, and
wherein the push bar is configured such that when one side of the push bar with respect to the bridge in a longitudinal direction of the push bar is pressed, the other side of the push bar with respect to the bridge in the longitudinal direction moves upward, and when pressure is released, the push bar is returned to an original position thereof.
3 . The protective cover according to claim 1 , wherein the coupling protrusion protrudes to have a curvature gradually lowering toward the center of the impact resistance member, and
wherein a retaining surface protruding perpendicularly outward is formed on one side end of the coupling protrusion which gets contact with one end of the push bar.
4 . The protective cover according to claim 1 , wherein a loop surface is further included on the holding part to minimize an exposed area of the seated coupling protrusion by covering an upper portion of the fixing groove.
