A tube clamp may include a tube body, an abutting block, and a clamping member, and a pivot connecting portion is formed at a lateral edge of the tube body. A through hole penetrates through a lateral surface of the tube body, and each of two lateral edges of the through hole has a first locating protrude having a stepped surface. The abutting block is slidably installed in the through hole, and each of two lateral sides of the abutting block comprises a second locating protrude, and the two second locating protrudes are respectively coupled with the two first locating protrudes. The clamping member has a protruding portion and a pulling portion. Through pulling the pulling portion, the protruding portion is adapted to press the abutting block into an inner space of the tube body so as to achieve the clamping effect of the tube clamp.
1. A tube clamp comprising:
a tube body,
an abutting block,
a clamping member, and
a pivot connecting portion formed at a lateral edge of the tube body;
wherein a through hole penetrates through a lateral surface of the tube body at a position corresponding to the pivot connecting portion, and each of two lateral edges of the through hole having a first locating protrude comprising a stepped surface; a lateral surface of the abutting block, which is faced to the through hole, is formed into a concave surface;
wherein the abutting block is slidably installed in the through hole, and each of two lateral sides of the abutting block includes a second locating protrude, and the two second locating protrudes respectively coupled with the two first locating protrudes so as to position the abutting block;
wherein the clamping member has a protruding portion and a pulling portion, and the protruding portion includes a connecting hole at an eccentric portion thereof and a bolt configured to penetrate through two parallel ear portions and the connecting hole to pivotally connect the clamping member with the pivot connecting portion of the tube body; through pulling the pulling portion, the protruding portion is adapted to press the abutting block into an inner space of the tube body so as to achieve the clamping effect of the tube clamp,
wherein a lower portion of the tube body of the tube clamp is formed into an engaging portion which has a larger outer diameter than the tube body; a step-shaped abutting edge is formed at an upper end of an inner periphery of the engaging portion, and a plurality of vertical ribs horizontally protrude from an inner wall of the engaging portion.
2. The tube clamp of claim 1 , wherein the two parallel ear portions horizontally protrude from an outer periphery of the tube body at different heights to form the pivot connecting portion therebetween, and the clamping member is pivotally connected to the tube body through the two parallel ear portions so as to have vertical axis of rotation when pulled.
3. The tube clamp of claim 2 , wherein the two parallel ear portions, which are separated apart, horizontally protrude from the outer periphery of the tube body at the same height to form the pivot connecting portion therebetween, and the clamping member is pivotally connected to the tube body through the two ear portions so as to have horizontal axis of rotation when pulled.
4. The tube clamp of claim 1 , wherein the tube body is a hollow cylinder.
5. The tube clamp of claim 1 , wherein the concave surface of the abutting block has a plurality of convexes thereon.
6. The tube clamp of claim 1 , wherein the concave surface of the abutting block has a plurality of horizontal ribs thereon.
