[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a high-precision angle sensor, including a sensor body 1 and an anti-interference mechanism 3. The bottom of the sensor body 1 is connected with a mounting plate 2. An anti-interference mechanism 3 is arranged on one side of the surface of the sensor body 1, and a mounting mechanism 4 is arranged on one side of the surface of the sensor body 1;

[0021] The anti-interference mechanism 3 includes a lower protective shell 301, a lower connecting plate 302, a threaded hole 303, a bolt 304, a rotary knob 305, an upper connecting plate 306, a fixing hole 307 and an upper protective shell 308. One side of the surface of the sensor body 1 is fixedly connected with the lower protective shell 301. One side of the surface of the lower protective shell 301 is fixedly connected with the lower connecting plate 302. One side of the surface of the lower connecting plate 302 is provided with the threaded hole 303. The internal thread of the threaded hole 303 is connected with the bolt 304. One end of the bolt 304 is fixedly connected with the rotary knob 305. One end of the bolt 304 penetrates through the upper connecting plate 306. One side of the surface of the upper connecting plate 306 is provided with the fixing hole 307. One end of the upper connecting plate 306 is fixedly connected with the upper protective shell 308. Through the settings of the lower protective shell 301, the lower connecting plate 302, the threaded hole 303, the bolt 304, the rotary knob 305, the upper connecting plate 306, the fixing hole 307 and the upper protective shell 308, when in use, first, the upper protective shell 308 is sleeved on the upper part of the sensor body 1, and at the same time, the upper connecting plate 306 and the lower connecting plate 302 are aligned and fitted with each other. At this time, the fixing hole 307 and the threaded hole 303 are aligned. Then, one end of the bolt 304 penetrates through the upper connecting plate 306 through the fixing hole 307, and then is threadedly connected with the lower connecting plate 302 through the threaded hole 303. Rotate the rotary knob 305. At this time, the rotary knob 305 drives the bolt 304 to rotate so as to tighten the bolt 304. At this time, the upper protective shell 308 and the lower protective shell 301 wrap the surface of the sensor body 1. Since both the lower protective shell 301 and the upper protective shell 308 are made of graphene, and graphene can prevent electromagnetic interference due to its unique physical and chemical properties, the sensor body 1 can be prevented from being affected by electromagnetic interference and thus its accuracy can be avoided.

[0022] Further, the lower protective shell 301 is made of graphene, the upper protective shell 308 is sleeved on the upper part of the sensor body 1, and the upper protective shell 308 is made of graphene. Through the settings of the lower protective shell 301 and the upper protective shell 308, when in use, the lower protective shell 301 and the upper protective shell 308 made of graphene can prevent the sensor body 1 from being affected by electromagnetic interference when wrapping the sensor body 1.

[0023] Further, the bolt 304 penetrates through the upper connecting plate 306 through the fixing hole 307, and the bolt 304 is threadedly connected with the lower connecting plate 302 through the threaded hole 303. Through the setting of the bolt 304, when in use, the bolt 304 can connect the upper connecting plate 306 and the lower connecting plate 302, so that the lower protective shell 301 and the upper protective shell 308 wrap the sensor body 1.

[0024] Furthermore, the installation mechanism 4 includes a limit groove 401, a calibration groove 402, a movable groove 403, a fitting groove 404, a calibration post 405, a limit block 406, a connecting rod 407, a spring 408, and a pull ring 409.

A limit block 406 is fitted inside the movable groove 403. One end of the limit block 406 is fixedly connected to a connecting rod 407. A spring 408 is sleeved on the surface of the connecting rod 407. One end of the connecting rod 407 is fixedly connected to a pull ring 409. Through the settings of the limit groove 401, the calibration groove 402, the movable groove 403, the fitting groove 404, the calibration post 405, the limit block 406, the connecting rod 407, the spring 408, and the pull ring 409, when the sensor body 1 needs to be installed, the pull ring 409 is pulled. At this time, the pull ring 409 drives the limit block 406 to move into the movable groove 403 through the connecting rod 407, and at the same time the spring 408 undergoes compressive deformation. When the limit block 406 is completely fitted inside the movable groove 403, the bottom of the sensor body 1 is fitted inside the fitting groove 404, and at the same time the calibration post 405 is fitted inside the calibration groove 402. At this time, the limit groove 401 is aligned with the movable groove 403. The force applied to the pull ring 409 is released. At this time, the spring 408 rebounds and drives the limit block 406 to return to its original position. At this time, one end of the limit block 406 is fitted inside the limit groove 401, and the other end is fitted inside the movable groove 403. Thus, the limit block 406 fixedly installs the sensor body 1 on the surface of the mounting plate 2.

[0025] Furthermore, the fitting groove 404 is dimensionally compatible with the bottom of the sensor body 1. The calibration post 405 is fixedly connected inside the fitting groove 404. The calibration post 405 is dimensionally compatible with the calibration groove 402.

[0026] Furthermore, one end of the limit block 406 is fitted inside the limit groove 401. One end of the pull ring 409 penetrates through the mounting plate 2. Through the setting of the limit block 406, during use, when one end of the limit block 406 is fitted inside the movable groove 403 and the other end is fitted inside the limit groove 401, the limit block 406 can fix the sensor body 1 on the surface of the mounting plate 2.

[0027] Furthermore, the spring 408 is disposed inside the movable slot 403. One end of the spring 408 is fixedly connected to the limiting block 406, and the other end of the spring 408 is fixedly connected to the mounting plate 2. By providing the spring 408, during use, the spring 408 can drive the limiting block 406 to return to its original position through elastic deformation.

[0028] Working principle: When it is necessary to install the sensor main body 1, pull the pull ring 409. At this time, the pull ring 409 drives the limiting block 406 to move inside the movable slot 403 through the connecting rod 407. At the same time, the spring 408 undergoes compressive deformation. When the limiting block 406 is completely fitted inside the movable slot 403, at this time, the bottom of the sensor main body 1 is fitted inside the fitting slot 404, and at the same time, the calibration post 405 is fitted inside the calibration slot 402. At this time, the limiting slot 401 is aligned with the movable slot 403. Release the force applied to the pull ring 409. At this time, the spring 408 undergoes elastic deformation to drive the limiting block 406 to return to its original position. At this time, one end of the limiting block 406 is fitted inside the limiting slot 401, and the other end is fitted inside the movable slot 403. Thus, the limiting block 406 fixedly installs the sensor main body 1 on the surface of the mounting plate 2. The upper protective shell 308 is sleeved on the upper part of the sensor main body 1. At the same time, the upper connecting plate 306 is aligned with and abuts against the lower connecting plate 302. At this time, the fixing hole 307 is aligned with the threaded hole 303. Subsequently, one end of the bolt 304 passes through the fixing hole 307 and penetrates the upper connecting plate 306, and then is threadedly connected to the lower connecting plate 302 through the threaded hole 303. Rotate the rotary knob 305. At this time, the rotary knob 305 drives the bolt 304 to rotate to tighten the bolt 304. At this time, the upper protective shell 308 and the lower protective shell 301 wrap the surface of the sensor main body 1. Since both the lower protective shell 301 and the upper protective shell 308 are made of graphene, and graphene can prevent electromagnetic interference due to its unique physical and chemical properties, the sensor main body 1 can be prevented from being affected by electromagnetic interference and thus affecting its accuracy.
