Ring groove type standard parts are different from traditional anchor bolts in tightening force caused by torque rotation. Huck standard parts use Hooke's law basic principle, through Huck professional equipment, under the action of unilateral tension, pull the bolt rod and select the side ring sleeve, extrude the internal smooth ring sleeve into the concave groove of the extruder screw, making the ring sleeve and anchor bolt produce 100% fusion, resulting in long-term tightening Tightening force. The whole tightening process only takes about 5-8 seconds. (1) Insert the Huck anchor bolt into the connection hole, and put the ring sleeve on the Huck anchor bolt. (2) place the special installation tool on the end of the bolt rod, press and hold the power switch, and the special tool starts. The claw on the top of the double drum rivet head fastens the tail end of the bolt rod, and the top of the head promotes the ring sleeve straight until all the gaps are removed. (3) the ring sleeve is pressed on the annular pipe groove of the bolt rod at the top of the head, After the clamping force of the design scheme is achieved, the end of the bolt rod is separated from the bolt rod, and the whole installation process is carried out.
