If the height of the laser displacement sensor is not appropriate, the laser beam may not be accurately irradiated on the target, thereby affecting the accuracy of the measurement results.

[0005] Therefore, a highly sensitive pipe displacement measuring device is proposed. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0032] like Figure 1 As shown, the utility model provides a high-sensitivity pipe displacement measuring device, including a mounting sleeve 1, the inner wall of the mounting sleeve 1 is fixedly connected to a laser displacement sensor 2, one end of the laser displacement sensor 2 is mounted with a lens 3, the end of the laser displacement sensor 2 away from the lens 3 is mounted with a screw cap 4, and the surface of the mounting sleeve 1 is provided with an adjustment structure 5. By setting the adjustment structure 5, it is easy to adjust the height of the laser displacement sensor 2, thereby avoiding the situation where the laser beam cannot be accurately irradiated on the target due to an inappropriate height of the laser displacement sensor 2, thereby ensuring the accuracy of the pipe displacement measurement result.

[0033] The specific setting and function of the adjustment structure 5 will be described in detail below.

[0034] like Figure 2 - Figure 6As shown, the adjustment structure 5 includes a fixed block 501, which is fixedly connected to the arc surface of the installation sleeve 1. A threaded cylinder 502 is fixedly connected to the surface of the fixed block 501. A screw 503 is threadedly connected to the inner wall of the threaded cylinder 502. The end of the screw 503 away from the threaded cylinder 502 is rotatably connected to the base plate 504. The arc surface of the threaded cylinder 502 is fixedly connected to two cylinders 505. A limiting rod 506 is slidably inserted into the inner wall of the cylinder 505. The limiting rod 506 is fixedly connected to the surface of the base plate 504. When the installation sleeve 1 moves, it drives the cylinder 505 to slide along the surface of the limiting rod 506. The limiting rod 506 limits the movement path of the cylinder 505, thereby limiting the movement path of the installation sleeve 1, thereby preventing the installation sleeve 1 from rotating during movement. The surface of the screw rod 503 is fixedly connected to a driving ring 507. The arc surface of the driving ring 507 is fixedly connected to a number of round rods 508. The rotation of the round rods 508 drives the driving ring 507 to rotate, and the rotation of the driving ring 507 drives the screw rod 503 to rotate. The round rods 508 facilitate the rotation of the driving ring 507, and thus facilitate the rotation of the screw rod 503. The arc surface of the driving ring 507 is fixedly connected to a circular ring 509. The arc surface of the circular ring 509 is provided with a number of circular grooves 510. The surface of the bottom plate 504 is fixedly connected to a fixing plate 511. The surface of the fixing plate 511 is slidably penetrated by a latch 512. The size of the latch 512 matches the size of the circular groove 510. The latch 512 will be inserted into the circular groove 510. The latch 512 limits the height of the driving ring 507, thereby limiting the height of the laser displacement sensor 2. The arc surface of the latch 512 is covered with a spring 513, and the two ends of the spring 513 are fixedly connected to the latch 512 and the fixing plate 511 respectively. The latch 512 will be inserted into the circular groove 510 with the help of the contraction force of the spring 513, and the spring 513 can improve the stability of the latch 512 inserted into the circular groove 510. The end of the latch 512 away from the ring 509 is fixedly connected to a rope 514, and the end of the rope 514 away from the latch 512 is fixedly connected to a pull ring 515. The surface of the bottom plate 504 is fixedly connected to a hook 516. The movement of the pull ring 515 will pull the rope 514, and the movement of the rope 514 will drive the latch 512 to move. The movement of the latch 512 will slide in the fixed plate 511 and gradually come out of the circular groove 510. When the latch 512 moves, the spring 513 will be stretched. When the latch 512 comes out of the circular groove 510, the spring 513 is in a stretched state. Then the pull ring 515 is hung on the surface of the hook 516. The hook 516 reaches the position of limiting the pull ring 515, thereby limiting the position of the latch 512, thereby avoiding the need to pull the pull ring 515 all the time when rotating the screw rod 503.The arc surface of the threaded barrel 502 is fixedly connected to two brackets 517, and the end of the bracket 517 away from the threaded barrel 502 is fixedly connected to an arc plate 518, and a sponge pad 519 is glued to one side of the arc plate 518. The movement of the threaded barrel 502 will drive the bracket 517 to move, and the movement of the bracket 517 will drive the arc plate 518 to move. The movement of the arc plate 518 will drive the sponge pad 519 to slide along the surface of the screw rod 503. The sponge pad 519 is used to facilitate wiping off impurities attached to the surface of the screw rod 503, thereby preventing dust from wearing the teeth and affecting the rotation of the screw rod 503.

[0035] The overall working principle is that when the height of the laser displacement sensor 2 needs to be adjusted, the pull ring 515 is first pulled. The movement of the pull ring 515 will pull the rope 514. The movement of the rope 514 will drive the pin 512 to move. The pin 512 will slide in the fixed plate 511 and gradually come out of the circular groove 510. The pin 512 will stretch the spring 513 when it moves. When the pin 512 comes out of the circular groove 510, the spring 513 is in a stretched state. Then the pull ring 515 is hung on the surface of the hook 516. The hook 516 reaches The position of the pull ring 515 is limited, thereby limiting the position of the latch 512, and then the round rod 508 is rotated. The rotation of the round rod 508 will drive the driving ring 507 to rotate. The rotation of the driving ring 507 will drive the screw rod 503 to rotate. The rotation of the screw rod 503 will rotate on the surface of the bottom plate 504. When the screw rod 503 rotates, the threaded barrel 502 will move on the surface of the screw rod 503 with the help of the thread. The movement of the threaded barrel 502 will drive the bracket 517 to move. The movement of the bracket 517 will drive the arc plate 518 to move. The movement of the arc plate 518 will drive the sponge pad 519 along the screw rod The surface of 503 slides, and the sponge pad 519 is convenient for wiping off impurities on the surface of the screw rod 503, thereby preventing dust from wearing the teeth and affecting the rotation of the screw rod 503. The movement of the threaded barrel 502 will move in the direction away from the bottom plate 504. The movement of the threaded barrel 502 will drive the fixed block 501 to move. The movement of the fixed block 501 will drive the installation sleeve 1 to move in the direction away from the bottom plate 504. When the installation sleeve 1 moves, it will drive the cylinder 505 to slide along the surface of the limit rod 506. The limit rod 506 can limit the movement path of the cylinder 505. , thereby limiting the moving path of the mounting sleeve 1, thereby preventing the mounting sleeve 1 from rotating during movement. The mounting sleeve 1 will drive the laser displacement sensor 2 to move during movement. When the laser displacement sensor 2 moves to a suitable position, remove the pull ring 515 from the hook 516, and then release the pull ring 515. The pin 512 will be inserted into the circular groove 510 with the help of the contraction force of the spring 513. The pin 512 reaches the limiting drive ring 507, thereby limiting the height of the laser displacement sensor 2, thereby further limiting the height of the laser displacement sensor 2.
