Problems solved by technology

[0002] At present, the structure of the detection coil used to detect signals is usually assembled and connected by four aluminum blocks. On the one hand, the process is relatively cumbersome, and on the other hand, the assembly and assembly are relatively complicated. Secondly, the signal shielding effect is slightly affected due to the connection of multiple screws. , since the assembly screws are made of 304 stainless steel, there will be a small impact on the magnetic field
[0003] In addition, the existing probe coil structure has a slight impact on the resonance point during the tuning and matching process, and the tuning and matching takes a long time. To solve this problem, the processing technology of the probe coil has been improved.

Abstract

The invention discloses a modified detection coil, comprising an integration structured detection coil frame (9), detection coil shielding plates (10) arranged at two sides in the width of the detection coil frame (9), and a detection coil wave guiding tube (13). The detection coil frame (9) is provided therein with a containing cavity. The containing cavity is provided therein with an adjustable capacitor (12) and a detection coil framework (11). One end of the adjustable capacitor (12) is fixedly arranged on the front end plate (9-3) of the detection coil frame (9) and the other end extends towards the containing cavity. One end of the detection coil framework (11) is fixedly arranged on the back end plate (9-4) of the detection coil frame (9) and the other end extends towards the containing cavity. One end of the detection coil wave guiding tube (13) is fixedly arranged on the front end plate (9-3) and the other end extends to the exterior part of the detection coil frame (9). The detection coil provided by the invention is simple in structure and can achieve an improved shielding effect.

Description

technical field [0001] The present invention relates to an improved search coil. Background technique [0002] At present, the structure of the detection coil used to detect signals is usually assembled and connected by four aluminum blocks. On the one hand, the process is relatively cumbersome, and on the other hand, the assembly and assembly are relatively complicated. Secondly, the signal shielding effect is slightly affected due to the connection of multiple screws. , Since the assembly screws are made of 304 stainless steel, there will be a small impact on the magnetic field. [0003] In addition, the existing probe coil structure has a slight impact on the resonance point during the tuning and matching process, and the tuning and matching takes a long time. To solve this problem, the processing technology of the probe coil has been improved. The present invention thus comes. Contents of the invention [0004] Based on the above problems, the purpose of the present ...
