Description

Technical Field

[0001] This utility model belongs to the field of measuring devices, specifically relating to a device for measuring the outer diameter and wall thickness of fiberglass pipes. Background Technology

[0002] With the rapid development of modern industry, fiberglass pipes have become an important alternative to traditional metal pipes, especially in environments with high requirements for pipe corrosion resistance, due to their advantages such as corrosion resistance, high temperature resistance, light weight, and convenient installation. In the production process of fiberglass pipes, the accurate measurement of outer diameter and wall thickness is crucial, as these parameters directly affect the strength, pressure resistance, and service life of the pipes.

[0003] In existing pipe outer diameter measuring devices, the measuring ends are stretched to fit against the outer wall of the pipe, thus fixing the measuring end to the pipe. The outer diameter of the pipe is then calculated by observing the length of the extended measuring ends.

[0004] During the measurement process, although the two ends of the stretch measuring ruler are in close contact with the outer wall of the pipe, the measuring ruler cannot be guaranteed to be completely aligned with the center of the pipe. In order to obtain more accurate measurement values, multiple measurements at different positions are required, which leads to slow measurement efficiency. Utility Model Content

[0005] To overcome the problem that existing pipe outer diameter measuring devices cannot ensure that the measuring ruler is completely aligned with the center of the pipe, and require multiple measurements at different locations to obtain more accurate measurements, resulting in slow measurement efficiency, a fiberglass pipe outer diameter and wall thickness measuring device is proposed.

[0006] The technical solution of this utility model is as follows: a fiberglass pipe outer diameter and wall thickness measuring device, including a fixed frame; it also includes a damping rotating rod and a measuring component; the damping rotating rod is rotatably arranged on the inner wall of the fixed frame, a toothed ring is fixedly connected to the outer wall of the damping rotating rod, two toothed plates are slidably arranged on the inner wall of the fixed frame, the two toothed plates mesh with the toothed ring, a fixed block is fixedly connected to the end of the toothed plate away from the toothed ring, a clamping block is arranged at the rear end of the fixed block, a first groove is opened at the upper end of the clamping block, a rotating wheel is rotatably arranged on the inner wall of the first groove, the front end of the damping rotating rod passes through the fixed frame and is fixedly connected to a knob, and a measuring component is arranged at the front end of the fixed frame.

[0007] Preferably, a connecting block is fixedly connected between the fixing block and the clamping block, and a second groove is provided through the rear end of the fixing frame, with the connecting block slidably disposed on the inner wall of the second groove.

[0008] Preferably, a limiting plate is fixed to the outer side of the toothed plate, and a limiting groove is opened on the inner wall of the fixing frame. The limiting groove has a trapezoidal cross section, and the limiting plate is adapted to the limiting groove. A third groove is opened through the upper end of the fixing block, and the third groove is adapted to the toothed plate.

[0009] Preferably, the measuring assembly includes a first measuring scale, which is rotatably mounted on the outer wall of the damping rod and is located between the fixed frame and the knob.

[0010] Preferably, a second measuring ruler is slidably disposed on the inner wall of the first measuring ruler, a fixing groove is provided at the rear end of the second measuring ruler, a fixing rod is fixedly connected to the inner wall of the fixing groove, and a positioning plate is slidably disposed on the inner wall of the fixing groove.

[0011] Preferably, a retaining ring is fixed to the front end of the positioning plate, the retaining ring is compatible with the fixing rod, and a storage box is fixed to the right end of the fixing frame, with a locking plate slidably installed on the right end of the storage box.

[0012] Preferably, the pipe body is provided at the rear end of the fixing frame, and the outer wall of the clamping block is arc-shaped, with the outer wall of the clamping block fitting against the inner wall of the pipe body.

[0013] The beneficial effects of this utility model are as follows: By rotating the knob, the toothed ring is driven to rotate, and the two toothed plates on both sides of the toothed ring move in opposite directions, so that the upper surface of the clamping block is in contact with the inner wall of the pipe body. Since the toothed plates can no longer extend outward, rotating the knob will drive the entire device to rotate along the inner wall of the pipe body, so that the center of the fixing frame coincides with the center of the pipe body. This solves the problem that the first measuring ruler cannot ensure that it is completely aligned with the center of the pipe body. In order to obtain more accurate measurement values, multiple measurements at different positions are required, which leads to slow measurement efficiency. Attached Figure Description

A fixed frame 1 is fixedly connected to a knob 108. A measuring component is provided at the front end of the fixed frame 1. By rotating the knob 108, the toothed ring 102 is rotated, and the two toothed plates 103 on both sides of the toothed ring 102 move in opposite directions, so that the upper surface of the clamping block 105 is in contact with the inner wall of the pipe body 7. Since the toothed plates 103 cannot continue to extend outward, rotating the knob 108 will drive the entire device to rotate along the inner wall of the pipe body 7, so that the center of the fixed frame 1 coincides with the center of the pipe body 7. This solves the problem that the first measuring ruler 201 cannot ensure that it is completely aligned with the center of the pipe body 7. In order to obtain more accurate measurement values, multiple measurements at different positions are required, which leads to slow measurement efficiency.

[0022] Please see Figures 1-4In this embodiment, a connecting block 2 is fixedly connected between the fixing block 104 and the clamping block 105. A second groove 3 is provided through the rear end of the fixing frame 1. The connecting block 2 is slidably disposed on the inner wall of the second groove 3. A limiting plate 4 is fixedly connected to the outer side of the toothed plate 103. A limiting groove 5 is provided on the inner wall of the fixing frame 1. The limiting groove 5 has a trapezoidal cross section. The limiting plate 4 is adapted to the limiting groove 5. A third groove 6 is provided through the upper end of the fixing block 104. The third groove 6 is adapted to the toothed plate 103. A pipe body 7 is provided at the rear end of the fixing frame 1. The outer wall surface of the clamping block 105 is arc-shaped. The outer wall surface of the clamping block 105 is in contact with the inner wall surface of the pipe body 7. By providing the limiting groove 5, it can be ensured that the toothed plate 103 will not shift during movement. By providing the arc-shaped clamping block 105, the clamping block 105 is tightly in contact with the inner wall surface of the pipe body 7.

[0023] Please see Figures 1-5 In this embodiment, the measuring component includes a first measuring ruler 201. The first measuring ruler 201 is rotatably mounted on the outer wall of the damping rotating rod 101. The first measuring ruler 201 is located between the fixing frame 1 and the knob 108. A second measuring ruler 202 is slidably mounted on the inner wall of the first measuring ruler 201. A fixing groove 203 is opened at the rear end of the second measuring ruler 202. A fixing rod 204 is fixedly connected to the inner wall of the fixing groove 203. A positioning plate 205 is slidably mounted on the inner wall of the fixing groove 203. A retaining ring 206 is fixedly connected to the front end of the positioning plate 205. The retaining ring 206 is adapted to the fixing rod 204. A storage box 207 is fixedly connected to the right end of the fixing frame 1. The right end of the storage box 207... A locking plate 208 is slidably installed. By rotating the first measuring ruler 201 and pulling the second measuring ruler 202 outward, the locking plate 208 is slidably installed to remove the positioning plate 205 from the storage box 207. The positioning plate 205 is inserted into the inner wall of the fixing groove 203 to make the retaining ring 206 and the fixing rod 204 lock together and fix each other. Then, the second measuring ruler 202 is pulled to make the left end face of the positioning plate 205 fit against the inner wall of the pipe body 7. The scale lines on the surface of the second measuring ruler 202 are observed and the reading is recorded. Then, the length of the outer diameter of the pipe body 7 is measured by the same steps, so that the thickness of the pipe body 7 wall can be calculated.

[0024] In use, first, rotate the knob 108 to drive the toothed ring 102 to rotate. The two toothed plates 103 on both sides of the toothed ring 102 move in opposite directions, so that the upper surface of the clamping block 105 is in contact with the inner wall of the pipe body 7. Since the toothed plates 103 cannot continue to extend outward, rotating the knob 108 will drive the entire device to rotate along the inner wall of the pipe body 7, so that the center of the fixing frame 1 coincides with the center of the pipe body 7, thus avoiding the problem of inaccurate subsequent measurements.

[0025] Then, by rotating the first measuring ruler 201 and pulling the second measuring ruler 202 outward, the sliding locking plate 208 removes the positioning plate 205 from the storage box 207. By inserting the positioning plate 205 into the inner wall of the fixing groove 203, the retaining ring 206 and the fixing rod 204 are locked together. Then, the second measuring ruler 202 is pulled to make the left end face of the positioning plate 205 fit against the inner wall of the pipe body 7. By observing the scale lines on the surface of the second measuring ruler 202 and recording the reading, the length of the outer diameter of the pipe body 7 is measured by the same steps, and the thickness of the pipe body 7 wall can be calculated.

[0026] Through the above steps, by rotating the knob 108, the toothed ring 102 is rotated, and the two toothed plates 103 on both sides of the toothed ring 102 move in opposite directions, so that the upper surface of the clamping block 105 is in contact with the inner wall of the pipe body 7. Since the toothed plates 103 cannot continue to extend outward, rotating the knob 108 will drive the entire device to rotate along the inner wall of the pipe body 7, so that the center of the fixing frame 1 coincides with the center of the pipe body 7. This solves the problem that the first measuring ruler 201 cannot ensure that it is completely aligned with the center of the pipe body 7, and that multiple measurements at different positions are required to obtain more accurate measurement values, which leads to slow measurement efficiency.
