Description

Technical Field

[0001] This utility model relates to the field of sensor supports, and in particular to a shock-absorbing and adjusting base for an optical magnetic field sensor. Background Technology

[0002] An optical magnetic field sensor, also known as a magneto-optical sensor, is a device that utilizes the polarization state of light to perform sensor functions. When a beam of polarized light passes through a medium, if an external magnetic field exists in the direction of beam propagation, the light will rotate by an angle as it passes through the polarization plane; this is the magneto-optical effect. By measuring this rotation angle, the applied magnetic field can be measured.

[0003] Before using the optical magnetic field sensor, the sensor support needs to be installed in the designated position, and then the optical magnetic field sensor is installed inside the sensor support. Currently, the sensor support only uses screws and the support to tighten and fix the sensor. After installation, the angle cannot be adjusted, and the inability to adjust to the optimal angle will affect the detection accuracy.

[0004] To address this issue, a shock-absorbing adjustment base for an optical magnetic field sensor is proposed. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figure 1-3 This utility model provides an embodiment of a shock-absorbing adjustment base for an optical magnetic field sensor, comprising a mounting plate 1, a circular sleeve 2 fixedly connected to the top of the mounting plate 1, a circular ring 3 slidably connected inside the circular sleeve 2, an alignment plate 23 fixedly connected to the top of the front of the circular ring 3, and a scale groove 24 provided on the top of the circular sleeve 2. By setting the alignment plate 23 and the scale groove 24, the user can easily observe the rotation angle of the circular sleeve 2, thereby facilitating the adjustment of the circular ring 3 and the sensor to a suitable angle. A rotating rod 4 is fixedly connected inside the circular ring 3 via a bearing, and a support base 5 is fixedly connected to the surface of the rotating rod 4. Spring pieces 6 are fixedly connected to both sides of the top of the support base 5, and rubber sheets are fixedly connected to the surface of the spring pieces 6. The rubber pad 7 has a triangular groove 18 on its surface. The bottom of the ring 3 contacts the top of the mounting plate 1. By setting the triangular groove 18, the friction between the rubber pad 7 and the sensor can be increased, thus improving the fixing effect of the rubber pad 7 on the sensor. The surface of the rotating rod 4 is fixedly connected to the worm gear 8. The inside of the ring 3 is fixedly connected to the worm 9 through the bearing. The worm 9 meshes with the worm gear 8. The rear side of the inner cavity of the hexagonal sleeve 12 is fixedly connected to the limiting ring 19. The inner wall of the limiting ring 19 contacts the surface of the worm 9. By setting the limiting ring 19, the hexagonal sleeve 12 can be limited, thus preventing the hexagonal sleeve 12 from detaching from the hexagonal plate 11. The front of the circular sleeve 2 has an arc-shaped opening 10. Reference Figure 2-4 The front end of the worm 9 passes through the arc-shaped opening 10 and extends to the front side of the circular sleeve 2, where a hexagonal plate 11 is fixedly connected. A hexagonal sleeve 12 is slidably fitted onto the surface of the hexagonal plate 11. The surface of the worm 9 contacts the inner wall of the arc-shaped opening 10. A pull plate 20 is fixedly connected to the front of the hexagonal sleeve 12. By setting the pull plate 20, it is convenient for the user to pull the hexagonal sleeve 12, avoiding the situation where the user cannot effectively pull the hexagonal sleeve 12. A tension spring 13 is fixedly connected to the front of the hexagonal plate 11. The front end of the tension spring 13 is fixedly connected to the inside of the hexagonal sleeve 12. A hexagonal groove 14 is opened on the front of the circular sleeve 2. The rear end of the hexagonal sleeve 12 extends into the inside of the hexagonal groove 14. A rubber sleeve 22 is fixedly connected to the back of the hexagonal sleeve 12. The back of the rubber sleeve 22 contacts the inner wall of the hexagonal groove 14. By setting the rubber sleeve 22, the rear side of the hexagonal sleeve 12 can be protected to prevent the hexagonal sleeve 12 from colliding with the inner wall of the hexagonal groove 14.

[0014] Reference Figure 1-2 The top of the support base 5 is provided with a fixing component, which includes a bolt 15. The bolt 15 is set on the top of the support base 5, and a spring piece 6 is sleeved on the surface of the bolt 15. A nut 16 is threadedly connected to the left side of the surface of the bolt 15. A limiting sleeve 17 is sleeved on the surface of the nut 16. The right side of the limiting sleeve 17 is fixedly connected to the surface of the spring piece 6. By setting the bolt 15, nut 16 and limiting sleeve 17 to work together, the sensor can be quickly fastened to the top of the support base 5. The tightness of the nut 16 can be adjusted to adapt to sensors of different sizes. The limiting sleeve 17 can prevent the nut 16 from loosening and falling off in a vibration environment.

[0015] Reference Figure 2-4 The top of the ring 3 is provided with a protective component, which includes a corrugated sleeve 21. The corrugated sleeve 21 is fixedly connected to the top of the ring 3, and the inner wall of the corrugated sleeve 21 is fixedly connected to the surface of the support base 5. By setting the corrugated sleeve 21, dust can be blocked without affecting the rotation of the support base 5 and the ring 3, preventing dust from entering the interior of the sleeve 2 and affecting the worm gear 8 and worm 9.

[0016] Working principle: The user first installs the mounting plate 1 in the appropriate position using screws, then inserts the optical magnetic field sensor into the inner side of the spring 6. Next, the user rotates the bolt 15 with a tool. The bolt 15, through the nut 16, compresses the spring 6, causing the spring 6 to drive the rubber pad 7 to press and fix the sensor. The rubber pad 7 can dampen the sensor. When the angle needs to be adjusted, the hexagonal sleeve 12 is pulled forward. After the hexagonal sleeve 12 disengages from the hexagonal slot 14, it is rotated. The hexagonal sleeve 12 drives the worm gear 9 to rotate through the hexagonal plate 11. The worm gear 9 drives the rotating rod 4 and support base 5 to rotate through the worm wheel 8. The support base 5 drives the sensor to rotate. Simultaneously, the hexagonal sleeve 12 can be pushed left or right. The hexagonal sleeve 12 drives the ring 3 to rotate through the hexagonal plate 11 and the worm gear 9. The ring 3 drives the sensor to rotate through the rotating rod 4 and support base 5. After reaching the appropriate angle, the hexagonal sleeve 12 is inserted into the hexagonal slot 14. The tension spring 13 prevents the hexagonal sleeve 12 from moving, thus achieving the advantage of easy angle adjustment.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
