Tension testing device for building material detection

Abstract

The utility model discloses a building material detects and uses tensile test device, including base and material main part, the top fixedly connected with the fixing frame of base, the top of fixing frame is equipped with electric push rod, the inside top swing of fixing frame has inserted transmission rod, the bottom fixedly connected with horizontal plate of transmission rod, the utility model discloses a building material detects and uses tensile test device, and the control box control electric push rod drives transmission rod and horizontal plate to move upwards through, and horizontal board drives two second connecting plates in the upper portion to move upwards, and two second connecting plates in the upper portion pull material main part, because the bevel of first fixed block and the bevel of second fixed block mutually fit, so when the tensile force is greater, second fixed block will be close to material main part direction, namely the clamping force of material main part is greater, avoids the material main part to appear the situation of falling off in the test process to carry out the normal operation of tensile test like this.
