[0027] The sidewall of the slide 22 has a through slot 221. The lower end of the support ring 25 is fixedly connected to the first support plate 251. The upper ends of both sides of the support ring 25 are provided with second arc-shaped grooves 252. The side of the support ring 25 is fixedly connected to the second support plate 253. The lower end of the first support plate 251 is fixedly connected to the inner bottom wall of the U-shaped bracket 2. The second arc-shaped groove 252 corresponds to the first arc-shaped groove 33. One end of the second support plate 253 is fixedly connected to the inner sidewall of the U-shaped bracket 2.
[0028] The groove 22 is used to place the slider 34 and provide support for the slider 34. The first support plate 251 and the second arc-shaped groove 252 are used to support the support ring 25 and prevent the support ring 25 from shifting position.
[0029] The protective block 24 is located at the center inside the support ring 25. The outer wall of the protective block 24 is attached to the inner wall of the PE pipe body 1, and the inner wall of the support ring 25 is attached to the outer wall of the PE pipe body 1.
[0030] The presence of connector 23 is used to support the protective block 24, that is, to stably maintain the protective block 24 inside the PE pipe body 1. The protective block 24 is used to prevent the PE pipe body 1 from being impacted and collapsing.
[0031] A stop block 311 is fixedly connected to the upper end of the vertical block 31, an auxiliary block 341 is fixedly connected to the inner side of the slider 34, and an electric push rod 3411 is fixedly connected to the upper end of the auxiliary block 341.
[0032] The vertical block 31 is used to support the test ring 3 to maintain the stability of the test ring 3, and the stop block 311 is used to prevent the vertical block 31 from falling out of the slot 21.
[0033] The vertical block 31 passes through the interior of the slot 21, the stop block 311 is located above the U-shaped bracket 2, the slider 34 is slidably connected to the slot 22, the auxiliary block 341 passes through the interior of the slot 221, and the upper end of the electric push rod 3411 is fixedly connected to the top wall of the slot 221.
[0034] The electric push rod 3411 is used to push the auxiliary block 341 to slide along the slot 221, that is, to drive the test ring 3 to move closer to the support ring 25 via the slider 34. The electric push rod 3411 is electrically connected to the pressure block 32. The pressure block 32 is equipped with a sensor. The movement of the electric push rod 3411 will push the pressure block 32 to move synchronously towards the outer surface of the PE pipe body 1.

At this time, the support ring 25 is attached to the lower outer surface of the PE pipe body 1, and the protective block 24 is attached to the inner wall of the PE pipe body 1. Then, the electric push rod 3411 can be controlled to extend to push the auxiliary block 341 down along the slot 221. The auxiliary block 341, via the slider 34, will drive the test ring 3 towards the support ring 25. As the test ring 3 moves down... The pressure block 32 in the test ring 3 will press against the outer surface of the PE pipe body 1 to apply pressure. The movement of the electric push rod 3411 will push the pressure block 32 to move synchronously towards the outer surface of the PE pipe body 1. When the pressure block 32 is subjected to the extrusion pressure on the outer surface of the PE pipe body 1, the sensor inside the pressure block 32 will transmit the extrusion pressure borne by the pressure block 32 to the external display device. At this time, the pressure resistance of the PE pipe body 1 can be fed back according to the degree of pressure applied by the downward movement of the pressure block 32. Under the action of the protective block 24, the pressure-bearing part of the PE pipe body 1 can be prevented from collapsing. Under the action of the support ring 25, the pressure-bearing opposite part of the PE pipe body 1 can be prevented from being damaged.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
