[0017] Compared with the prior art, the present invention provides a magnetic field measuring device, which has the following beneficial effects:

[0018] 1. This utility model provides a magnetic field measuring device. Through the adjustment mechanism, with the cooperation of a lead screw, a threaded seat, a limiting rod, a limiting block, a motor, a frame, a motor, a slide groove, a threaded seat, a slider, and a docking plate, the threaded seat and the limiting block can drive the frame and the magnetic field measuring device to move back and forth.

[0019] 2. This utility model provides a magnetic field measuring device. Through a disassembly and assembly mechanism, with the cooperation of a fixed frame, insert frame, insert block, slide rod, sleeve, connecting plate, spring, strip groove, force plate, and base frame, the elastic effect of the spring can push the sleeve and insert plate to both sides, thereby allowing the insert block to be directly inserted into the insert frame.

Detailed Implementation

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] Example 1

[0029] Please refer to Figures 1-5 As shown, a magnetic field measuring device includes a support plate 1, an adjustment mechanism 2 at the upper end of the support plate 1, a horizontal plate 3 on the inner side of the adjustment mechanism 2, a disassembly and assembly mechanism 4 at the upper end of the horizontal plate 3, a fixed seat 5 at the upper end of the disassembly and assembly mechanism 4, and a magnetic field measuring device 6 fixedly mounted at the upper end of the fixed seat 5.

[0030] The two ends of the horizontal plate 3 are fixedly installed to the bottom end of the connecting plate 212.

[0031] Example 2

[0032] Please refer to Figures 2-3 As shown, the adjustment mechanism 2 includes a lead screw 21, the front and rear ends of which are rotatably mounted to the inner side of the support plate 1. A threaded seat 22 is installed on the external thread of the lead screw 21. A limit rod 23 is fixedly connected to the upper part of the lead screw 21. A limit block 24 is slidably connected to the external part of the limit rod 23. A motor 25 is fixedly installed at the rear end of the support plate 1. A frame 26 is fixedly connected to the upper end of the limit block 24. A motor 27 is fixedly installed at the lower inner side of the frame 26. A lead screw 28 is installed at the output end of the motor 27. A sliding groove 29 is opened through the inner sidewall of the frame 26. A threaded seat 210 is installed on the external thread of the lead screw 28. A slider 211 is fixedly connected to the front end of the threaded seat 210. A docking plate 212 is fixedly connected to the front end of the slider 211.

[0033] The top end of the lead screw 21 is connected to the output end of the motor 25 for transmission, and the upper end of the threaded seat is fixedly connected to the lower end of the limit block 24.

[0034] The slider 211 is internally slidably mounted to the slide groove 29.

[0035] In this scheme, the limiting block 24 can slide horizontally on the limiting rod 23, thereby limiting the threaded seat 22.

[0036] In this solution, the position of the magnetic field measuring device 6 can be precisely adjusted by adjusting mechanism 2. The advantage of adjustment is particularly evident when measuring magnetic field sources of different sizes. It can flexibly change the position of the magnetic field measuring device 6 according to the size and shape of the magnetic field source, so that the distance between the magnetic field measuring device 6 and the magnetic field source is always kept within the required range. This precise distance control effectively reduces the error of the measurement results and greatly improves the performance of the entire device in the actual measurement process, providing more accurate and reliable data for magnetic field measurement work.

[0037] Example 3

[0038] Please refer to Figures 4-5 As shown, the disassembly and assembly mechanism 4 includes a fixed frame 41, the lower end of which is fixedly installed to the upper end of the horizontal plate 3. symmetrical insert frames 42 are fixedly installed on both sides of the interior of the fixed frame 41. Insert blocks 43 are movably installed inside the insert frames 42. Slide rods 44 are symmetrically fixedly connected inside the fixed base 5. Sleeves 45 are slidably connected on both sides of the slide rods 44. A connecting plate 46 is fixedly connected between the sleeves 45. Springs 47 are sleeved on both sides of the middle part of the slide rods 44. A strip groove 48 is opened through the rear end of the fixed frame 41. A force-applying plate 49 is fixedly connected to the front end of the sleeves 45. A base frame 410 is fixedly installed at the lower end of the sleeves 45.

[0039] The insert 43 is L-shaped, one end of the spring 47 is fixedly connected to the middle of the slide rod 44, and the other end is fixedly connected to the inside of the sleeve 45.

[0040] The top of the force-applying plate 49 extends out of the fixed seat 5 through the strip groove 48, and the force-applying plate 49 is slidably installed inside the strip groove 48.

[0041] The base frame 410 is L-shaped, and the bottom end of the base frame 410 is fixedly connected to the rear end of the insert block 43.

[0042] In this scheme, the sleeve 45 gradually approaches the slide bar 44, thereby reducing the gap between the two sets of insert blocks 43, making it easier to place the insert blocks into the fixed frame 41. Under the elastic effect of the spring 47, the sleeve 45 can be squeezed, allowing the insert blocks 43 to be directly inserted into the insert frame 42, which facilitates the quick installation of the magnetic field measuring device 6. Conversely, it facilitates the quick disassembly of the device.

[0043] In this solution, the disassembly and assembly of the device is completed quickly through the disassembly and assembly structure, which greatly improves work efficiency and reduces the time cost in the installation and maintenance process.

[0044] The working principle and usage procedure of this device are as follows: When installing the magnetic field measuring device 6, the force plates 49 on both sides can be pulled by hand to move the force plates 49 within the strip groove 48. This causes the sleeve 45 to gradually approach the slide rod 44. Simultaneously, the front sleeve 45 can be moved synchronously by the connecting plate 46 to drive the rear sleeve 45. As the sleeve 45 approaches, it will drive the insertion block 43 to move synchronously through the base frame 410. At this time, the spring 47 will be compressed and deformed. Then, the insertion block 43 is placed into the fixed frame 41. After releasing the force plates 49, the elastic effect of the spring 47 will push the sleeve 45 to slide away from the slide rod 44. This will cause the sleeve 45 to drive the insertion block 43 to gradually move away synchronously through the base frame 410, so that the insertion block 43 will directly insert into the insertion frame 42, thereby completing the installation of the fixed seat 5 and the insertion block 42. The magnetic field measuring device 6 is installed and fixed to facilitate its use. By starting motor 25, the motor drives the lead screw to rotate, which in turn drives the threaded seat to move back and forth. The threaded seat can drive the frame 26 to move synchronously through the limit block 24, thereby adjusting the front and rear position of the magnetic field measuring device 6. At the same time, motor 27 can be started, which drives the lead screw 28 to rotate. The lead screw 28 drives the threaded seat 210 to move up and down, and the threaded seat 210 drives the horizontal plate 3 to move synchronously through the slider 211 and the docking plate 212, thereby adjusting the height of the measuring device. This ensures that the distance between the magnetic field measuring device 6 and the magnetic field source is within the required range when measuring magnetic field sources of different sizes, reducing the error of the measurement results and simplifying the operation.
