[0002] Pipes are also known as pipe fittings, which are the collective term for components in a piping system that serve functions such as connection, control, direction change, flow distribution, sealing, and support. Pipes are ubiquitous in daily life, and to ensure production standards, pipes must meet certain quality requirements after production. The wall thickness, outer diameter, and inner diameter of the pipe being tested are all important technical indicators, making accurate measurement of these data crucial. Previously, pipe testing typically involved manual, handheld tools to gradually measure the outer diameter and wall thickness, a time-consuming and inefficient method. Utility Model Content

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a pipe testing device according to this utility model.

[0029] like Figures 1 to 5As shown, this utility model discloses a pipe testing device, including a base 1, a column 2 and a display screen at one end of the top surface of the base 1, and a diameter detection component 3 for detecting the diameter of the pipe slidably mounted on the column 2. The diameter detection component 3 and the display screen are electrically connected. The diameter detection component 3 records the pipe diameter through a scale 9 on the column 2 and transmits the data to the display screen for display. The diameter detection component 3 includes a slider 301 slidably mounted inside the column 2, a first touch sensor 302 on the bottom surface of the free end of the slider 301, and a first photographic sensor 303 on one side of the slider 301. The first photographic sensor 303, the first touch sensor 302, and the display screen are electrically connected. When it is necessary to detect the diameter of the pipe, the slider 301 can be slid down. The slider 301 drives the first touch sensor 302 and the first photographic sensor 303 to move down. The first touch sensor 302 stops after contacting the top of the pipe. Then the first touch sensor 302 sends a signal to the first photographic sensor 303. The first photographic sensor 303 works and sends the value detected from the scale 9 on the column 2 to the display screen for display.

[0030] To prevent deviation between the first touch sensor 302 and the highest point of the pipe from affecting the detection results, a protrusion 4 is symmetrically arranged at the center of the free end of the slider 301, and a first sliding post 5 is vertically slidable on the protrusion 4, passing through the protrusion 4. A first limiting piece 7 is provided at the top of the first sliding post 5 to prevent the first sliding post 5 from sliding off the protrusion 4. A first auxiliary plate 11 is also connected between the bottom ends of the two first sliding posts 5, and a first spring 6 is sleeved on the first sliding post 5 between the first auxiliary plate 11 and the protrusion 4. When slider 301 moves downward, it drives the first auxiliary plate 11 to descend via the spring on the first sliding post 5. Sliding slider 301 continues to descend when the bottom surface of the first auxiliary plate 11 contacts the highest point of the pipe. As the first touch sensor 302 moves towards the first auxiliary plate 11, it compresses the first spring 6. The sensor stops working when it contacts the top surface of the first auxiliary plate 11. This ensures that even when the center of the highest point of the pipe is not aligned with the center of the first touch sensor 302, the first touch sensor 302 can still accurately detect the pipe diameter via the first auxiliary plate 11. When slider 301 needs to move upward, the first spring 6 extends, and when slider 301 contacts the first limiting plate 7, the first limiting plate 7 drives the first auxiliary plate 11 to move back to its initial position via the first limiting post.

[0031] like Figure 1 and Figure 2As shown, a driving device 19 is also provided on the column 2, and a first sliding groove 201 is provided on the column 2 along its height direction. The slider 301 is slidably disposed in the first sliding groove 201. Specifically, the driving device 19 includes a first motor 1901 disposed on the column 2, the first motor 1901 being connected to an external power supply, and a screw 1902 rotatably disposed in the first sliding groove 201. The first motor 1901 is connected to the screw 1902, and the screw 1902 is threadedly connected to the slider 301. Figure 1 As shown, a control box 25 is provided on the base 1, and a display screen is located on the control box 25. Control buttons are also provided on the control box 25. The first motor 1901 on the drive device 19 is electrically connected to the control buttons on the control box 25. When the diameter detection component 3 needs to work, the first motor 1901 can be started via the control buttons. The first motor 1901 drives the screw 1902 to rotate, and the slider 301 on the diameter detection component 3, which is threadedly connected to the screw 1902, will drive the diameter detection component 3 to work downwards, thereby realizing the diameter detection component 3 detecting the diameter of the pipe. The first touch sensor 302 on the diameter detection component 3 will send a signal to the first motor 1901 to stop its operation.

[0032] Preferably, a hanging plate 8 is provided below the diameter detection component 3, and a thickness detection component 10 for detecting the pipe thickness is provided on the hanging plate 8. The thickness detection component 10 is electrically connected to the display screen. Scales 9 are provided on both the hanging plate 8 and the column 2. The thickness detection component 10 records the pipe thickness through the scales 9 on the hanging plate 8 and transmits the data to the display screen for display. Figure 3 and Figure 4As shown, the thickness detection assembly 10 includes a sliding frame 1001 that slides along the length of the hanging plate 8. An electric push rod 1002 with its telescopic end facing outwards is provided on one side of the sliding frame 1001. The electric push rod 1002 is connected to an external power supply. A second photographic sensor 1007 facing the scale 9 of the hanging plate 8 is provided on the sliding frame 1001. A detection plate 1003 is located at the telescopic end of the electric push rod 1002 via a fixing block, and the detection plate 1003 is located above the electric push rod 1002. An inclined block 1004 is provided at the end of the detection plate 1003 away from the sliding frame 1001, and the inclined block 1004 is positioned with the left side lower than the right side. A connecting block 1005 is also provided at the top of the detection plate 1003, and a second touch sensor 1006 is provided on the end face of the connecting block 1005 facing the inclined block 1004. The second touch sensor 1006, the second photographic sensor 1007, and the display screen are electrically connected, so that the second photographic sensor 1007 can send the detected value to the display screen for display. Of course, a tension spring 1008 is also provided between the connecting frame and the sliding frame 1001, with one end of the tension spring 1008 connected to the connecting frame and the other end connected to the sliding frame 1001. In order to limit the sliding frame 1001 at the vertical plate 8, a stop block 82 is provided on the side wall of the vertical plate 8. It should be noted that the top corner of the inclined block 1004 is flush with the bottom surface of the first auxiliary plate 11, which facilitates the movement of the inclined block 1004 into the pipe.

[0033] It should be noted that the first touch sensor 302 and the electric push rod 1002 are connected by an electrical signal. When the first touch sensor 302 on the diameter detection assembly 3 touches the top surface of the first auxiliary plate 11 and stops the slider 301 from moving down, the first touch sensor 302 sends a signal to the electric push rod 1002. The electric push rod 1002 drives the detection plate 1003 and the inclined block 1004 to move towards the pipe through the fixed block. When the inclined block 1004 moves, the inclined surface of the inclined block 1004 will contact the end face of the pipe. Under the action of the inclined surface of the inclined block 1004, the sliding frame 1001 will move down through the detection plate 1003, the fixed block and the electric push rod 1002. When the end face of the pipe contacts the second touch sensor 1006, the electric push rod 1002 stops working and sends a signal to the second photographic sensor 1007. The second photographic sensor 1007 detects the scale 9 on the hanging plate 8 and sends the detected data to the display screen for display.

[0034] To prevent the pipe end face from being too thin and failing to accurately contact the second touch sensor 1006, thus affecting the normal operation of the thickness detection component 10. For example... Figure 5As shown, a second sliding post 12 is slidably mounted on the connecting block 1005, and the second sliding post 12 passes through the connecting block 1005. A second limiting piece 14 is provided at one end of the second sliding post 12, and a second auxiliary plate 15 is provided at the other end. A second spring 13 is sleeved on the second sliding post 12 between the second auxiliary plate 15 and the connecting block 1005. When the detection plate 1003 drives the connecting block 1005 to move towards the pipe, the connecting block 1005 will drive the second auxiliary plate 15 to move towards the pipe through the second spring 13 on the second sliding post 12. After the second auxiliary plate 15 contacts the end face of the pipe, it continues to move. At this time, the connecting block 1005 will compress the second spring 13 until the second touch sensor 1006 contacts the second auxiliary plate 15, thereby achieving the purpose of detecting the wall thickness of the pipe. When the electric push rod 1002 moves the connecting block 1005 on the detection plate 1003 toward the initial position via the fixed plate, the compressed second spring 13 begins to extend, and after the second limiting plate 14 contacts the connecting block 1005, the second limiting plate 14 moves the second auxiliary plate 15 toward the initial position via the second sliding column 12.

[0035] As a further improvement, a second sliding groove 81 is formed on the hanging plate 8, and the detection plate 1003 is slidably disposed within the second sliding groove 81, which improves the stability of the detection plate 1003 relative to the hanging plate 8. To facilitate the placement of the pipe onto the base 1, the base 1 is provided with a sliding platform 16 for placing the pipe, and the sliding platform 16 includes support plates 161 symmetrically arranged around the center of the base 1, with multiple rollers 162 horizontally rotatable between the two support plates 161. Figure 1 As shown, a flat plate 17 is mounted above the base 1 via support legs, and a through hole 18 is formed on the flat plate 17. Mounting plates 23 are slidably mounted opposite each other within the through hole 18, and clamping plates 24 are connected to the bottom surface of each mounting plate 23. Simultaneously, an adjustment device is provided on the flat plate 17 to control the movement of the two mounting plates 23. The adjustment device can drive the clamping plates 24 on the mounting plates 23 to move closer together, achieving the purpose of stabilizing the clamping of the pipe by the two clamping plates 24.

[0036] The adjustment device for controlling the sliding of the mounting plate 23 within the through hole 18 includes a second motor 22 mounted on the plate 17. The second motor 22 is connected to an external power supply via a control button in the control box 25. A threaded rod 21 is also rotatably mounted within the through hole 18, with two threads on the rod being threadedly connected to the two mounting plates 23 within the through hole 18. One end of the threaded rod 21 passes through the plate 17 and extends outward. The second motor 22 is connected to the extended end of the threaded rod 21 via a transmission unit. The transmission unit includes gears 20 located at the output end of the second motor 22 and the extended end of the threaded rod 21, respectively, and the two gears 20 mesh. Specifically, when it is necessary to move the clamping plates 24 closer together, the second motor 22 can be activated via the control button. The second motor 22 drives the threaded rod 21 to rotate, causing the two mounting plates 23 threadedly connected to the threaded rod 21 to move their corresponding clamping plates 24 closer together, thus achieving the purpose of clamping and fixing the pipe placed on the sliding table 16. When it is necessary to release the clamping plate 24 from the pipe, the second motor 22 can be started by controlling the button to rotate in the reverse direction. The second motor 22 drives the positive and negative threaded rods 21 to rotate in the reverse direction. At this time, the two mounting plates 23, which are threaded to the positive and negative threaded rods 21, will drive the connected clamping plates 24 to move away from each other, thus achieving the purpose of clamping the pipe with the clamping plates 24. It should be noted that in addition to using gear 20 for transmission, the transmission part can also use a pulley and transmission belt connection. Of course, the adjustment device can also be replaced by a push rod. Specifically, a push rod can be set on the plate 17 at one end of each mounting plate 23. This will not be elaborated on in detail here, as long as it meets the usage requirements.

[0037] Instructions for use: Place the pipe on the sliding table 16, then activate the adjustment device via the control button. The adjustment device causes the clamping plate 24 connected to the mounting plate 23 to move closer together, thus clamping and fixing the pipe. Next, activate the drive device 19. The drive device 19 lowers the diameter detection component 3, and after the diameter detection component 3 contacts the pipe, it begins to detect the pipe's diameter. At this time, the thickness detection component 10 starts working. After the second touch sensor 1006 on the thickness detection component 10 contacts the pipe end, the thickness detection component 10 sends the pipe wall thickness data to the display screen of the control box 25 for the operator to view and record. After the pipe diameter and wall thickness are detected, send a signal via the control button to the electric push rod 1002 on the thickness detection component 10 to return it to its initial position. After the electric push rod 1002 returns to its initial position, it sends a signal to the drive device 19. The drive device 19 then raises the diameter detection component 3 and the thickness detection component 10 on the diameter detection component 3 back to their initial positions and then stops working. When it is necessary to remove the pipe from the sliding table 16, the control button connected to the adjustment component can be used to start the operation, and drive the two mounting plates 23 on the adjustment component to move away from each other. That is, the clamping plates 24 connected to the two mounting plates 23 also move away from each other, thereby releasing the clamping work of the two clamping plates 24 on the pipe. Then the pipe placed on the sliding table 16 can be removed.
