[0006] The testing mechanism comprises a slide rail block, the slide rail block is slidably connected between the outer rail ring and the inner rail ring, the side of the slide rail block is rotatably connected with a meshing gear, the side of the slide rail block away from the meshing gear is fixedly connected with a slide rod block, the end of the slide rod block away from the slide rail block is slidably connected with a vertical connecting rod, the upper and lower ends of the vertical connecting rod are fixedly connected with an electromagnetic wave transmitter, the top of the vertical connecting rod is fixedly connected with a linkage thin rod, the end of the linkage thin rod away from the vertical connecting rod is fixedly connected with a fixed wheel frame, and the side of the fixed wheel frame is rotatably connected with a guide The rail wheel, a reciprocating rail frame is arranged below the guide rail wheel, the inner wall of the inner rail ring is fixedly connected with a top cross bar, the top surface of the top cross bar is fixedly connected with a vertical support rod, the top end of the vertical support rod is fixedly connected with an upper support frame, the top end of the upper support frame is rotatably connected with a rotating shaft connecting rod, the top end of the slide rail block is fixedly connected with a bending connecting rod, the bottom end of the bending rod is fixedly connected with the supporting frame, the top surface of the inner rail ring is fixedly connected with a tooth block, and the tooth block is meshed with the meshing gear, the bending connecting rod is fixedly connected with the rotating shaft connecting rod, and an external motor is used to drive the gear. The meshing gears connected to the gears are driven to rotate, so that the meshing gears mesh with the tooth blocks on the inner rail ring, and the meshing gears drive the slide rail block to slide between the inner rail ring and the outer rail ring. At the same time, the vertical connecting rod is driven by the fixed wheel frame connected to the linkage thin rod, so that the fixed wheel frame slides along the reciprocating rail frame through the guide wheel on the side. When the guide wheel moves from the highest point of the reciprocating rail frame to the lowest point, the movement of the guide wheel drives the connected fixed wheel frame to drive the linkage thin rod to move, so that the linkage thin rod drives the connected vertical connecting rod to move from top to bottom along the slide rod block, thereby allowing the electromagnetic The wave transmitter transmits an electromagnetic signal, and changes the position of the reflected signal of the electromagnetic wave transmitter through the movement of the vertical connecting rod, so as to test whether there is a strength difference in the magnetometer when testing the magnetic strength at different angles and orientations. At the same time, when the tooth block on the meshing gear meshing inner rail ring rotates, the slide block will make a circular motion around the center of the inner rail ring, so that the slide block can rotate around the upper support frame through the bending connecting rod and the rotating shaft connecting rod.

At this time, the sleeve frame is subjected to the gravity of the magnetometer and moves downward along the vertical short rod through the ring rod seat and compresses the spring. Subsequently, the spring is compressed and releases the elastic force to offset the gravity of the sleeve frame, thereby using the vertical short rod to compress the spring downward, which plays a buffering role for the magnetometer and prevents the bottom of the magnetometer from being impacted and causing the outer shell to deform, thereby affecting the reception of magnetic signals.

[0012] S3: Subsequently, a liquid medium may be added into the side arc plate to test the influence of the liquid medium on the reception of electromagnetic signals. During the test, the electromagnetic wave transmitters at both ends of the vertical connecting rod are allowed to emit electromagnetic signals, and the position of the reflected signal of the electromagnetic wave transmitter is changed by the movement of the vertical connecting rod, so as to test whether there is a strength difference when the magnetometer tests the magnetic force at different angles and orientations;

[0013] S4: Then, when the meshing gear meshes with the tooth block on the inner rail ring and rotates, the slide block will make a circular motion around the center of the inner rail ring, so that the slide block can rotate around the upper support frame through the bending connecting rod and the rotating shaft connecting rod. The overall structure of the slide block changes the direction of the magnetometer receiving the electromagnetic signal of the electromagnetic wave transmitter through rotation, so as to test whether the magnetometer has a test blind spot;

[0014] S5: Then, put the magnetometer into the sleeve ring, so that the magnetometer falls from the sleeve ring and contacts the inner bottom surface of the sleeve frame.

After the inclined slot bar is pressed by the bending slide bar, it pulls the positioning arc plate to move, so that the positioning arc plate drives the connected telescopic rod to move;

[0016] S7: When the sleeve frame moves downward, the sleeve frame drives the bending slide bar to move downward, and the bending slide bar moves downward to pull the side connecting rod to move, and the side connecting rod moves to pull the top slide bar, so that the top slide bar pulls the side slot block and the flip hinge rod to deflect, and the flip hinge rod deflects around the hinge seat as a node. At this time, the flip hinge rod flips to cover the cover plate on the top of the magnetometer;

[0017] S8: Finally, when the cover plate tends to be horizontal, the elastic spring resets and allows the handle to push the docking port downward to align the docking port with the top interface of the magnetometer, and align the interface with the upper structure of the magnetometer, so as to facilitate the quick connection of the test line and protect the interface of the magnetometer.

[0037] Working principle: The connected meshing gear 52 is driven to rotate by an external motor, so that the meshing gear 52 meshes with the tooth block on the inner rail ring 3, and the meshing gear 52 drives the slide rail block 51 to slide between the inner rail ring 3 and the outer rail ring 8. At the same time, the vertical connecting rod 54 is driven by the fixed wheel frame 57 connected to the linkage thin rod 56, so that the fixed wheel frame 57 slides along the reciprocating rail frame 59 through the side guide wheel 58. When the guide wheel 58 moves from the highest point of the reciprocating rail frame 59 to the lowest point, the movement of the guide wheel 58 drives the connected fixed wheel frame 57 to drive the linkage thin rod 56 to move, so that the linkage thin rod 56 drives the connected vertical connecting rod 54 to move from top to bottom along the slide rod block 53, from The electromagnetic wave transmitters 55 at both ends of the vertical connecting rod 54 emit electromagnetic signals, and the position of the reflected signal of the electromagnetic wave transmitter 55 is changed by the movement of the vertical connecting rod 54, so as to test whether there is a strength difference in the magnetic strength of the magnetometer at different angles and orientations. At the same time, when the meshing gear 52 meshes with the tooth block on the inner rail ring 3 and rotates, the slide rail block 51 will make a circular motion around the center of the inner rail ring 3, so that the slide rail block 51 rotates around the upper support frame 514 through the bending connecting rod 512 and the rotating shaft connecting rod 513. The overall structure of the slide rail block 51 changes the orientation of the magnetometer receiving the electromagnetic signal of the electromagnetic wave transmitter 55 through rotation, so as to test whether there is a test blind spot of the magnetometer.

[0038] The magnetometer is put into the sleeve ring 61, so that the magnetometer falls from the sleeve ring 61 and contacts the inner bottom surface of the sleeve frame 62. At this time, the sleeve frame 62 is subjected to the gravity of the magnetometer and moves downward along the vertical short rod 64 through the ring rod seat 63 and compresses the compression spring. Then, the compression spring releases its elastic force after being compressed to offset the gravity exerted on the sleeve frame 62, so that the vertical short rod 64 is used to compress the spring downward, which plays a buffering role for the magnetometer and prevents the outer shell from being deformed after the bottom of the magnetometer is impacted and affects the reception of magnetic signals. At the same time, the falling and contacting sleeve frame 62 drives the bending slide bar 68 to move downward together under the action of gravity, so that the bending slide bar 68 slides along the side of the inclined slot rod 67. After the inclined slot rod 67 is pressed by the bending slide bar 68, it pulls the positioning arc plate 66 to move, so that the positioning arc plate 66 drives the connected telescopic rod 65 to move, so that the positioning arc plate 66 is close to the sleeve frame 62 to clamp the side of the magnetometer, so as to prevent the magnetometer from tilting or shaking during the test and affecting the test results.

At this time, the flip hinge rod 75 flips and covers the cover plate 77 on the top of the magnetometer, and allows the docking port 710 on the cover plate 77 to be lifted up by the top of the magnetometer first, and the docking port 710 moves upward to drive the handle 79 to pull The elastic spring on the outside of the dynamic reset slide bar 711 is compressed. When the cover plate 77 tends to be horizontal, the elastic spring resets to allow the handle 79 to push the docking port 710 downward to move, so that the docking port 710 is aligned with the top interface of the magnetometer, and the interface is aligned with the upper structure of the magnetometer, which is convenient for quickly connecting the test line and protecting the magnetometer interface. At the same time, after the test is completed, the handle 79 is pulled by hand to make the handle 79 pull the docking port 710 and flip the cover plate 77, so that the cover plate 77 no longer blocks the magnetometer, which is convenient for installation and removal.

[0042] S2: The vertical connecting rod 54 is driven by the fixed wheel frame 57 connected to the linkage thin rod 56, so that the fixed wheel frame 57 slides along the reciprocating rail frame 59 through the side guide wheel 58. When the guide wheel 58 moves from the highest point of the reciprocating rail frame 59 to the lowest point, the movement of the guide wheel 58 drives the connected fixed wheel frame 57 to drive the linkage thin rod 56 to move, so that the linkage thin rod 56 drives the connected vertical connecting rod 54 to move from top to bottom along the slide block 53 to test the magnetometer;

[0043] S3: Subsequently, a liquid medium may be added into the side arc plate 2 to test the influence of the liquid medium on the reception of electromagnetic signals. During the test, the electromagnetic wave transmitters 55 at both ends of the vertical connecting rod 54 are allowed to transmit electromagnetic signals, and the position of the reflected signal of the electromagnetic wave transmitter 55 is changed by the movement of the vertical connecting rod 54, so as to test whether there is a strength difference when the magnetometer tests the magnetic force at different angles and orientations;

[0044] S4: Then, when the meshing gear 52 meshes with the gear block on the inner rail ring 3 and rotates, the slide rail block 51 will make a circular motion around the center of the inner rail ring 3, so that the slide rail block 51 can rotate around the upper support frame 514 through the bending connecting rod 512 and the rotating shaft connecting rod 513. The overall structure of the slide rail block 51 changes the direction of the magnetometer receiving the electromagnetic signal of the electromagnetic wave transmitter 55 through rotation, so as to test whether the magnetometer has a test blind spot;

[0045] S5: After that, the magnetometer is put into the sleeve ring 61, so that the magnetometer falls from the sleeve ring 61 and contacts the inner bottom surface of the sleeve frame 62. At this time, the sleeve frame 62 is subjected to the gravity of the magnetometer and moves downward along the vertical short rod 64 through the ring rod seat 63 and compresses the compression spring. Then, the compression spring is compressed and releases its elastic force to offset the gravity of the sleeve frame 62, so that the spring is compressed downward by the vertical short rod 64, which plays a buffering role for the magnetometer.

[0046] S6: The falling contact sleeve frame 62 drives the bending slide bar 68 to move downward under the action of gravity, so that the bending slide bar 68 slides along the side of the inclined slot bar 67. After the inclined slot bar 67 is pressed by the bending slide bar 68, it pulls the positioning arc plate 66 to move, so that the positioning arc plate 66 drives the connected telescopic rod 65 to move;

[0047] S7: When the sleeve frame 62 moves downward, the sleeve frame 62 drives the bending slide bar 68 to move downward, and the bending slide bar 68 moves downward to pull the side connecting rod 71 to move, and the side connecting rod 71 moves to pull the top sliding rod 73, so that the top sliding rod 73 pulls the side groove block 74 and the flip hinge rod 75 to deflect, and the flip hinge rod 75 deflects around the hinge seat 76 as a node. At this time, the flip hinge rod 75 flips to cover the cover plate 77 on the top of the magnetometer;

[0048] S8: Finally, when the cover 77 tends to be horizontal, the elastic spring resets to allow the handle 79 to push the docking port 710 downward to align the docking port 710 with the top interface of the magnetometer, and the interface is aligned with the upper structure of the magnetometer, which is convenient for quick connection of the test line and protects the interface of the magnetometer. At the same time, after the test is completed, the handle 79 is pulled by hand so that the handle 79 pulls the docking port 710 and flips the cover 77, so that the cover 77 no longer blocks the magnetometer, which is convenient for installation and removal.
