A sealing and clamping structure 2 is arranged outside the cylinder 112 and the cavity head 113. An installation structure 3 is arranged at the upper end of the fixture main body 111. The sealing and clamping structure 2 includes a first clamping body 211. The first clamping body 211 is installed outside the cavity head 113. A second clamping body 212 is installed outside the cavity head 113. The first clamping body 211 and the second clamping body 212 can be assembled. Sealing ports 213 are opened at the upper ends of the first clamping body 211 and the second clamping body 212. A rubber ring is fixedly arranged on the outer wall at the sealing port 213. Through this design, when using this copper tube fixture, first align the copper tube port with the inlet of the cavity head 113, make the copper tube port enter the inside of the cavity head 113, and insert the copper tube downward to make it enter the inside of the cylinder 112 and the fixture main body 111. Subsequently, assemble the first clamping body 211 and the second clamping body 212 to the outside of the cavity head 113, make the sealing port 213 contact the copper tube, and use the rubber ring arranged at the sealing port 213 to seal the connection of the device. At the same time, the copper tube can be clamped by the first clamping body 211 and the second clamping body 212. Subsequently, when air is passed through the copper tube, the device is safer and has better sealing performance during the airtight detection of the copper tube.

[0022] Further, a limiting ring 214 is sleeved outside the first clamping body 211 and the second clamping body 212. Through this design, when assembling the first clamping body 211 and the second clamping body 212, the limiting ring 214 sleeved outside them is used for limiting, making their assembly convenient and stable.

[0023] Further, a sliding block 215 is fixedly connected to the inner wall of the limiting ring 214. The sliding block 215 is slidably arranged inside a sliding groove 216, and the sliding groove 216 is opened inside the second clamping body 212. Through this design, when the limiting ring 214 is installed outside the first clamping body 211 and the second clamping body 212, the sliding block 215 slides inside the sliding groove 216 synchronously, realizing the limiting of the limiting ring 214, enabling it to be preferentially positioned during installation and making the installation more convenient.

The positioning block 217 is inserted inside a positioning groove 218, and the positioning groove 218 is opened inside the first clamping body 211. Through this design, when assembling the first clamping body 211 and the second clamping body 212, the positioning block 217 inserted inside the positioning groove 218 can be used for positioning, making their assembly more convenient.

[0025] Further, the installation structure 3 includes an installation seat 311. The installation seat 311 is fixedly connected to the outer walls of the first clamping body 211 and the second clamping body 212. An installation hole 312 is opened inside the inspection tool main body 111, and the installation hole 312 is opened inside the installation seat 311. An installation bolt 313 is installed inside the installation hole 312. Through this design, when using this copper pipe inspection tool, the clamping and sealing main body can be conveniently installed on the inspection tool main body 111, preventing it from falling off due to gas impact during use. When installing the first clamping body 211 and the second clamping body 212 to the upper end of the inspection tool main body 111, the first clamping body 211 and the second clamping body 212 can be placed on the upper end of the inspection tool main body 111 synchronously. At this time, the installation seat 311 is placed on the upper end of the inspection tool main body 111 synchronously. Subsequently, the installation bolt 313 is installed into the installation hole 312 opened inside the installation seat 311 and the inspection tool main body 111, and then it can be conveniently installed.

[0026] Further, there are two groups of installation seats 311, and the installation seats 311 are symmetrically arranged along the connection part of the first clamping body 211 and the second clamping body 212.

[0027] Working principle:

[0028] When using the copper tube inspection fixture, first align the copper tube port with the inlet of the cavity head 113 so that the copper tube port enters the interior of the cavity head 113, push the copper tube downward to enter the interior of the column 112 and the inspection fixture body 111, then assemble the first clamping body 211 and the second clamping body 212 to the outside of the cavity head 113, and use the limiting ring 214 to sleeve the first clamping body 211 and the second clamping body 212 to limit the position, so that the sealing port 213 contacts the copper tube, and use the rubber ring provided at the sealing port 213 to seal the device connection. At the same time, the first clamping body 211 and the second clamping body 212 can be used to tighten the copper tube, and then ventilation can be performed through the copper tube, so that the device can be safer and have better sealing performance when the copper tube is tested for airtightness.

[0029] When using the copper tube gauge, the clamping sealing body can be conveniently installed on the gauge body 111 to prevent it from falling off due to gas impact during use. When installing the first clamping body 211 and the second clamping body 212 to the upper end of the gauge body 111, the first clamping body 211 and the second clamping body 212 can be placed on the upper end of the gauge body 111 simultaneously, and the mounting seat 311 is placed on the upper end of the gauge body 111 at the same time. Then, the mounting bolt 313 is installed into the mounting hole 312 opened inside the mounting seat 311 and the gauge body 111, and the installation can be conveniently completed.
