[0013] See also Figures 1-2 In an embodiment of the utility model, a cable fixing structure includes a sensor tube shell 1, a mounting head 2 is provided at one end of the sensor tube shell 1, a sensor tail cover 3 is provided on one side of the mounting head 2, a locking shaft cap 6 is inserted into one side of the sensor tail cover 3, a locking nut 4 is provided at one end of the locking shaft cap 6, and a cable 5 passes through the interior of the sensor tube shell 1, the mounting head 2, the locking nut 4 and the locking shaft cap 6.

[0014] A locking shaft head 7 is provided on one end of the locking shaft cap 6 close to the side of the locking nut 4. The locking shaft head 7 is composed of multiple raised combined heads. The outer surface of the locking shaft cap 6 is provided with a thread. The locking nut 4 has different inner diameters at both ends, and the inner wall of the locking nut 4 is provided with a thread groove, which is convenient for fixing it on the locking shaft cap 6 through the locking nut 4. When the locking nut 4 is rotated, the locking shaft head 7 is contracted and squeezed onto the cable 5 by one end of the locking nut 4, and then the locking nut 4 is threadedly fixed to the locking shaft cap 6.

[0015] The sensor housing 1, the sensor tail cover 3 and the locking nut 4 are all made of 304 stainless steel, which can withstand high and low temperatures and have high corrosion resistance, and can maintain good performance in relatively harsh operating environments.

[0016] The assembly steps are as follows: first, connect the locking shaft cap 6 with the sensor tail cover 3, fix the two parts by welding, riveting, etc., then pass the armored cable through the locking shaft cap 6, and use the locking nut 4 to screw into the locking shaft cap 6. The claw structure above the locking shaft cap 6 is deformed to tighten the armor wire sheath to fix it, and the sensor as a whole can be in close contact with the armor wire sheath to achieve a full shielding effect.

[0017] The design of this fixed structure can meet the requirements of reliable cable fixation at the output end of the sensor used in harsh environments, and can be flexibly used on sensors of different dimensions. It has a simple and reliable structure and is easy to use.

[0018] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
