Definitions

• the present invention relates to a clamp used for connecting steel pipes such as temporary scaffolds and shelves. Background technology
• Conventionally used clamps generally have one end of the holding body and the holding rest pivoted.
• the base of the tightening bolt is connected to the other end of the holding body and a U-shaped recess is formed at the other end of the holding body. Then, the tip of the bolt is fitted into this concave groove, and a nut is screwed into the bolt to fasten it.
• the two clamps in order to assemble the pipes in parallel or orthogonally, the two clamps must be attached to each other with their bottoms facing each other or provided with a plurality of projections on the bottom of one clamp and the projections on the bottom of the other clamp.
• a method of squeezing a fitting hole, fitting a protrusion into the hole, and fixing by crimping was used. When the pipes were assembled obliquely, a circular window was provided at the bottom of both clamps, and a column fitted into the circular windows was loosely fitted and used as a universal clamp.
• the configuration of the clamp according to the present invention is characterized in that the holding rest 1 and one end of the holding body 4 are pivotally connected, and the other end of the holding body 1 is pivotally connected to both bases of the groove-shaped auxiliary holding body 10. Screw the bolt 11 into the tip of the auxiliary holder 10.
• the spherical portion at the tip of the bolt 11 is provided with a spherical receiving recess A2 on the outer surface of the other end of the holder 7, and in the case of a thin pipe, the spherical surface of the other end of the holder 4 is provided.
• the recess A 1 is pressed, and the pipes are uniformly pressed and held by the hinge portions of the holding body 1, the holding body 7, and the auxiliary holding body 10.
• a rectangular hole 1a is pierced in the holder 1
• a circular hole 2a is pierced in the holder 2
• the square hole 1a and the circular hole 2a are formed.
• the main shaft 3 composed of a prism and a cylinder is inserted, the main shaft 3 and the holding body 1 rotate at the same time by the prism of the main shaft 3, and the holding body 2 rotates by the cylindrical portion of the main shaft 3.
• the prism side of the main shaft 3 is fixed to the holder 1, the other end of the main shaft 3 forms a rotating plate 3 a, and the stopper 2 is pivotally attached to the holder 2 with the pin 5.
• the rotation stopper lid member 4 When the holding body 1 and the holding body 2 are used as a free clamp, the rotation stopper lid member 4 is pushed up to use the holding body 1 and the holding body 2 in a state where the rotation of the holding body 1 and the holding body 2 is released.
• the rotation stopper cover member 4 When the holding body 2 is fixed to be orthogonal or parallel to use, the rotation stopper cover member 4 is covered on the rotating plate 3 a of the main shaft 3 and the rotation of the holding body 1 and the holding body 2 is fixed and used.
