The present invention relates to a pipe clamp, more specifically to a pipe clamp having a first coupling frame, a second coupling frame, a connecting element, and a tightly contacting lever connected rotatably to each other and structured so as to surround the pipe one and a half times around, that is, 540 degrees, and, because the tightly contacting lever tightly adheres simultaneously to the outer circumferential surface of the first coupling frame, the pipe clamp having a superior pipe holding force and additionally preventing completely the possibility of having the clamp spontaneously open without the intention of a user. |

1. A clamp used with a circular pipe, the clamp comprising:
a first coupling frame having a half-cylindrical structure shaped to adhered to an outer circumferential surface of the pipe, the first coupling frame having an elastic packing attached to an inner circumferential surface thereof and a pair of protrusions formed on a left side thereof; a second coupling frame having a half-cylindrical structure shaped to be coupled with the first coupling frame to surround the pipe, a left side of the second coupling frame rotatably connected to a right side of the first coupling frame via a first hinge pin, the second coupling frame having an elastic packing attached to an inner circumferential surface thereof; a connecting member having a left end portion rotatably connected to a right side of the second coupling frame via a second hinge pin and a right end portion inserted between both protrusions of the first coupling frame; and a contact lever having a circular-arc tabular structure shaped to surround the pipe by an additional half turn by being adhered to the outer circumferential surface of the first coupling frame-, an axial support part having an eccentric structure formed on a left side of the contact lever to be connected rotatably to the right end portion of the connecting member via a third hinge pin. |
