[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an outer diameter measuring device for plastic pipe fittings, including a measuring rod 1 located above the pipe 15. Two clamping plates 5 are slidably fitted inside the measuring rod 1. A plurality of extension rods 6 are installed at both ends of the measuring rod 1. Chute 2 is provided in both the measuring rod 1 and the extension rod 6. A slider 4 is installed on the clamping plate 5, and the slider 4 corresponds to the chute 2. A plurality of extension plates 7 are installed on the lower side of the clamping plate 5. Pressure sensors 8 are installed on both the clamping plate 5 and the extension plate 7. One end of the clamping plate 5 close to the measuring rod 1 is provided with a pointer 13. The clamping plate 5 can be rotatably connected to the slider 4 to ensure that the clamping plate 5 can be vertically downward.
[0022] In this embodiment, connecting plates 3 are fixed at both ends of the measuring rod 1 and both ends of the extension rod 6. A plurality of first bolts are installed between adjacent two connecting plates 3. A through groove 10 is provided in the connecting plate 3, and the through groove 10 corresponds to the first bolt.
[0023] Specifically, when it is necessary to expand the measuring range of the device, place the extension rod 6 at both ends of the measuring rod 1 so that the chutes 2 are aligned with each other. Then pass the first bolt through the through groove 10 to fix the extension rod 6 and the measuring rod 1 through the first bolt, thereby extending the measuring range of the device.
[0024] The chute 2 located inside the measuring rod 1 is a V-shaped structure with high ends and low middle. The chute 2 located inside the extension rod 6 is an inclined linear structure with one high end and one low end. The chute 2 inside the measuring rod 1 corresponds to the chute 2 inside the extension rod 6. The pipe 15 is located between the two clamping plates 5, and the pressure sensor 8 is in contact with the pipe 15.
[0025] Specifically, place the clamping plates 5 on both sides of the pipe 15. Under the action of gravity, the clamping plates 5 move closer to the center, causing the clamping plates 5 to drive the pressure sensors 8 to contact the pipe 15, so as to measure the outer diameter of the pipe 15.
[0026] Connection grooves 9 are provided at one end of the clamping plate 5 away from the measuring rod 1 and one end of the extension plate 7. An insertion block 11 is fixed at the other end of the extension plate 7. The insertion block 11 corresponds to the connection groove 9. A plurality of second bolts 12 are installed between the insertion block 11 and the connection groove 9. A scale 14 is installed on the measuring rod 1, and the scale 14 corresponds to the pointer 13.
[0027] Specifically, the measuring range of the measuring rod 1 can be changed by increasing the number of extension plates 7, so as to ensure that the pressure sensor 8 can contact the pipe 15, thereby facilitating the measurement of the diameter of the pipe 15.
[0028] When it is necessary to install the extension plate 7, the insertion block 11 can be inserted into the connection groove 9, and then the extension plate 7 and the measuring rod 1 can be fixed through the second bolt 12.
