AI Technical Summary

Technical Problem

During the installation of the exhaust pipe clamp, if the two ends of the pipe clamp are not pressed together, it is easy to cause air leakage, causing environmental pollution and noise, and affecting the driving experience.

Method used

A clamping device is designed, including a base, a fixing arm, a clamping arm, a transmission rod and a rotating handle. The clamping arm and the inner arc surface of the fixing arm are driven to jointly clamp the pipe clamping clamping through the transmission rod to ensure that the pipe clamping and the pipe fittings are closely connected, and the installation is completed through a fastening structure such as bolts.

Benefits of technology

It effectively ensures the sealing of the pipe clamp after installation, prevents air leakage, simplifies operation, reduces costs, facilitates maintenance, and prevents exhaust gas leakage and noise, improving driving experience.

Abstract

The utility model provides a clamping device. The clamping device comprises a base, a fixed arm, a clamping arm, a transmission rod and a rotating handle. The fixed arm is fixedly arranged on the base; the clamping arm is configured to be rotationally arranged on the base; the fixed arm and the clamping arm are oppositely provided with inner arc surfaces; the transmission rod penetrates through the base or the fixed arm and is constructed to be pre-pressed together with the clamping arm through the elastic device; the rotating handle is configured to be in transmission connection with the transmission rod and is configured to drive the clamping arm to move in the direction close to the fixed arm in the process of rotating in the first direction so as to clamp the pipe hoop through the fixed arm and the clamping arm, and drive the clamping arm to move in the direction away from the fixed arm in the process of rotating in the second direction so as to clamp the pipe hoop through the fixed arm and the clamping arm. Therefore, the fixing arm and the clamping arm release the pipe hoop. The clamping device is used for assisting the installation process of the pipe hoop, the sealing performance after the pipe hoop is installed can be effectively guaranteed, and the situations such as air leakage at the joint of the pipe hoop are prevented.
