Description

Technical Field

[0001] This utility model relates to the field of vibration sensor equipment, specifically an anti-interference vibration sensor. Background Technology

[0002] When using existing vibration sensors, the limited space at the installation location caused repeated false signal transmissions. After multiple diagnostic checks, it was determined that the fault was caused by sensor interference. To improve equipment reliability, it is necessary to enhance the equipment's anti-interference capability and ensure production safety.

[0003] According to the patent document CN213586819U, a vibration sensor anti-interference protective shielding cover includes a metal housing with a cavity for housing the sensor. A connecting piece is integrally formed with the metal housing at one end and is used for adhesive connection to a pump body. An opening for the sensor's wiring harness to pass through is provided at the other end of the metal housing. In use, the integral formation of the connecting piece with the metal housing ensures the reliability of the metal housing's installation. The adhesive connection between the connecting piece and the pump body allows the metal housing to be removed from the pump body during sensor maintenance. While this solution achieves rapid overflow, it does not increase the fixing force between the protective cover and the sensor during use, which can easily lead to positional issues affecting monitoring and causing inconvenience.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: an anti-interference vibration sensor, including a base 1, a protective seat 2 fixed on the base 1, a reinforcing seat 3 fixed on the side of the protective seat 2, a cavity 4 inside the protective seat 2, a movable seat 5 movably installed inside the cavity 4, a sealing tube 6 fixed on the top of the movable seat 5, a cable 7 movably installed inside the sealing tube 6, a movable block 8 movably installed on the top of the protective seat 2, a threaded post 9 rotatably installed on the movable block 8, one end of the threaded post 9 movably installed on the top of the movable seat 5, a fixing groove 10 on the base 1, a movable rod 11 movably installed inside the fixing groove 10, a support rod 19 movably installed at one end of the movable rod 11, and the sealing tube 6 is an elastic rubber tube, which is sealed by wrapping the cable 7.

[0025] In this embodiment, a slider 13 is fixed to the top of the protective seat 2, and a groove is opened at the bottom of the movable block 8. The slider 13 is movably installed inside the groove through a support mechanism 14. A ring seat 17 is fixed on the inner wall of the protective seat 2, and a reset mechanism 15 is fixed to the top of the ring seat 17. One end of the reset mechanism 15 is movably in contact with the inner wall of the movable seat 5. An opening 26 is opened on the base 1, and a limiting hole 27 is opened on the inner wall of the opening 26. A magnet ring seat 18 is movably installed inside the limiting hole 27. A sensor body 16 is fixed on the magnet ring seat 18, and the sensor body 16 is movably installed inside the ring seat 17. The support mechanism 14 and the reset mechanism 15 are springs. The reset mechanism 15 pushes the movable seat 5 to move upward. After the movable seat 5 moves upward, it contacts one end of the threaded post 9, thereby avoiding shaking.

[0026] In this embodiment, a limiting groove 28 is formed on the inner wall of the fixing groove 10. A slot 29 is formed at one end of the limiting groove 28. A limiting block 24 and a protrusion 25 are movably installed inside the limiting groove 28. One end of the limiting block 24 is fixed to the side of the movable rod 11, and the protrusion 25 is fixed to the side of the support rod 19. A connecting groove 23 is formed on the support rod 19. A connecting block 21 is movably installed inside the connecting groove 23. One end of the connecting block 21 is fixed to the movable rod 11. The connecting block 21 is installed inside the connecting groove 23 via a rotating column 22. A strong magnet 12 is fixed to one end of the movable rod 11. A threaded hole 20 is formed on the movable rod 11. After the magnet ring seat 18 is installed inside the limiting hole 27, the sensor body 16 is left and right limited. After the sensor body 16 is installed inside the opening 26, it is positioned and limited for a second time.

[0027] Working principle: During use, the movable block 8 is moved outward, causing it and the threaded column 9 to move out of the top of the cavity 4. The movable seat 5, having lost its limiting force, moves upward and is removed. The sensor body 16 is then installed inside the cavity 4. The magnet ring seat 18 is installed inside the limiting hole 27 to achieve left and right limiting of the sensor body 16. After the sensor body 16 is installed inside the opening 26, it undergoes secondary positioning and limiting fixation. After the sensor body 16 is installed, one end of the cable 7 is passed through the sealing tube 6, which seals the cable 7. After the movable seat 5 is installed inside the cavity 4, the support mechanism 14 pushes the movable block 8 inward. The threaded column 9 is distributed on the top of the movable seat 5. Simultaneously, the threaded column 9 rotates, causing one end of the threaded column 9 to rotate and descend, thus squeezing the movable seat 5. The seat 5 moves downward under pressure. During the downward movement of the movable seat 5, the reset mechanism 15 is compressed. The movable seat 5 achieves compression according to the height of the sensor body 16. The compression of the movable seat 5 completes the upper and lower limit of the sensor body 16. After the sensor body 16 is installed, it is attracted to the point of use through the magnet ring seat 18 inside the limiting hole 27. According to the size of the space at the installation point, the movable rod 11 drives the support rod 19 to move. As the movable rod 11 moves, the position of the strong magnet 12 changes. The strong magnet 12 completes the multi-point limiting and fixing of the base 1. When the fixing point can be clamped and fixed, the movable rod 11 drives the limiting block 24 to move into the slot 29. After the movable rod 11 is rotated through the connecting block 21, the movable rod 11 and the support rod 19 cooperate to clamp and fix the base 1 at the point of use through the strong magnet.
