[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides the following technical solution: a PVC pipe thickness detection device, including a working frame 1, a first motor 2 fixedly installed on one side of the working frame 1, a first threaded rod 13 provided at the output end of the first motor 2, a movable frame 6 threadedly connected to the surface of the first threaded rod 13, a connecting plate 7 snapped into the inside of the movable frame 6, white paper pasted on the inner wall of the connecting plate 7, a soft ruler 8 fixedly installed on the surface of the white paper, a support plate 3 fixedly installed on the inner wall of the working frame 1, a connecting frame 4 fixedly installed on the top of the support plate 3, a second motor 9 fixedly installed on one side of the top of the connecting frame 4, a second threaded rod 18 provided at the output end of the second motor 9, a movable plate 20 threadedly connected to the surface of the second threaded rod 18, a connecting rod 19 fixedly installed at one end of the movable plate 20, a connecting pipe 17 fixedly installed at the other end of the movable plate 20, a second return spring 22 fixedly installed on the inner wall of the connecting pipe 17, a movable block 23 fixedly connected to one end of the second return spring 22, and a water-based pen 21 threadedly connected to the inside of the movable block 23.

[0022] In a specific embodiment of this utility model, the PVC pipe is placed on the inner wall of the connecting frame 4. The second motor 9 rotates the second threaded rod 18, causing the moving plate 20 to move the connecting rod 19 and connecting pipe 17 downwards. This brings the connecting rod 19 close to the inner wall of the PVC pipe for inspection. A water-based pen 21 at one end of the connecting pipe 17 is used to draw on a piece of white paper on one side of the measuring tape 8. The operator can clearly determine the thickness of the PVC pipe using the measuring tape 8, greatly improving the convenience and accuracy of the equipment. The first motor 2... The operation causes the first threaded rod 13 to rotate, which in turn moves the movable frame 6 and the connecting plate 7, allowing for adjustments to the position of the white paper and changes in the pen marks. This facilitates comparison of multiple PVC pipes, reduces replacement operations, and improves the efficiency of the equipment. The second return spring 22 generates elastic force, causing the water-based pen 21 to move along the inner wall of the connecting plate 7 through the movable block 23 inside the connecting pipe 17. The operator can rotate the water-based pen 21 to disassemble and replace it, or vice versa, rotate one end of the water-based pen 21 to the inner wall of the movable block 23 for installation.

[0023] In this embodiment: the operator rotates the nut 12 to remove the screw 11 from the inside of the movable frame 6, and disassembles the connecting plate 7 from the inside of the movable frame 6 for replacement. The operation is simple and reduces the difficulty of operating this equipment.

[0024] In this embodiment: when the operator pulls the connecting block 10, the sliding rod 15 moves the clamping plate 14 upward, placing the PVC pipe on the inner wall of the connecting frame 4. After releasing the connecting block 10, the elastic force generated by the first reset spring 16 causes the connecting block 10 to move the clamping plate 14 at the bottom of the sliding rod 15, clamping the PVC pipe, reducing the slippage of the PVC pipe during the inspection process, and improving the quality of the inspection.

[0025] The working principle and usage process of this utility model are as follows: After the utility model is installed, when the operator pulls the connecting block 10, the sliding rod 15 moves the clamping plate 14 upward, placing the PVC pipe on the inner wall of the connecting frame 4. At the same time, the connecting rod 19 extends into the interior of the PVC pipe. After releasing the connecting block 10, the elastic force generated by the first return spring 16 causes the connecting block 10 to move the clamping plate 14 at the bottom of the sliding rod 15, clamping the PVC pipe and reducing slippage during the PVC pipe inspection process. The second motor 9 rotates the second threaded rod 18, causing the moving plate 20 to move the connecting rod 19 and the connecting pipe 17 downward, bringing the connecting rod 19 close to the inner wall of the PVC pipe for inspection. The water-based pen 21 at one end of the connecting pipe 17 is used to draw ink on the soft surface. On the white paper on one side of the ruler 8, the operator can clearly know the thickness of the PVC pipe by observing the zero mark at the bottom of the ruler 8 and the position where the pen stops, greatly improving the convenience and accuracy of the equipment. The first motor 2 rotates the first threaded rod 13, which moves the moving frame 6 and the connecting plate 7. By adjusting the position of the white paper and changing the position of the pen, it is convenient to compare multiple PVC pipes and reduce the need for replacement. The elastic force generated by the second return spring 22 causes the water-based pen 21 to move along the inner wall of the connecting plate 7 through the moving block 23 inside the connecting pipe 17. The operator can rotate the water-based pen 21 to disassemble and replace it, or rotate one end of the water-based pen 21 to the inner wall of the moving block 23 for installation. All electrical equipment in this device is powered by an external power source.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
