The shape and material selection of the electrode are crucial for the performance and stability of the laser.

[0003] First, the negative electrode structure in the existing laser tube structure is generally fixedly connected to the laser tube. Since the negative electrode body plays a very important role during the use of the laser tube, in order to enable the laser tube to be stably used during use, it is necessary to regularly remove the negative electrode in the laser tube structure for inspection and maintenance. There is no connecting mechanism, so it is not convenient to disassemble and repair the negative electrode in the laser tube. Secondly, the negative electrode material in the laser tube structure will also have a great impact on the service life of the laser tube.

A material layer assembly is arranged inside the negative electrode body. A connecting mechanism is jointly arranged at one end of the laser tube body and one end of the connecting piece. The connecting mechanism includes a first connecting plate. One end of the first connecting plate is fixedly connected to one end of the connecting piece.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: As Figures 1-5 shown, the present invention provides a high-power carbon dioxide laser tube electrode structure, including a laser tube body 1. One side of the top end of the laser tube body 1 is penetrated with a positive electrode body 5. One end of the laser tube body 1 is movably provided with a connecting member 4, and one end of the connecting member 4 is fixedly connected with a negative electrode body 6 used in cooperation with the positive electrode body 5. A material layer assembly 3 is arranged inside the negative electrode body 6. A connecting mechanism 2 is jointly arranged at one end of the laser tube body 1 and one end of the connecting member 4. The connecting mechanism 2 includes a first connecting plate 21. One end of the first connecting plate 21 is fixedly connected with one end of the connecting member 4. Two first connecting holes 22 are formed at one end of the first connecting plate 21. One end of the laser tube body 1 is fixedly connected with a second connecting plate 24 used in cooperation with the first connecting plate 21, and a second connecting hole 25 used in cooperation with the two first connecting holes 22 is formed at one end of the second connecting plate 24. The inner walls of the corresponding first connecting hole 22 and second connecting hole 25 are jointly threadedly connected with a connecting bolt 27. Through the arrangement of the material layer assembly 3, it is convenient to increase the service life and stability during use of the laser tube structure. Through the connecting mechanism 2, the two connecting bolts 27 are screwed out from the corresponding first connecting hole 22 and second connecting hole 25, so that the first connecting plate 21 and the second connecting plate 24 are separated, thereby facilitating the removal of the negative electrode body 6 from the laser tube body 1 and facilitating the maintenance of the negative electrode body 6. Regular maintenance makes the laser tube structure more stable during use.

[0019] The material layer assembly 3 includes a conductive material layer 31. The outer surface of the conductive material layer 31 is fixedly connected with one side inner wall of the negative electrode body 6. The inner wall of the conductive material layer 31 is fixedly connected with a thermal stability material layer 32, and the inner wall of the thermal stability material layer 32 is fixedly connected with a chemical stability material layer 33. The inner wall of the chemical stability material layer 33 is fixedly connected with one side inner wall of the negative electrode body 6. The conductive material layer 31 makes the negative electrode body 6 more stable in guiding during use. The thermal stability material layer 32 ensures the stable operation of the laser and extends the service life. The chemical stability material layer 33 can ensure that the laser tube maintains stable performance during long-term use, avoiding problems such as air leakage and explosion due to non-external factors, thereby improving the overall performance and service life of the laser tube.

[0020] The negative electrode body 6 is cylindrical, which is convenient for better use of the negative electrode body 6.

[0021] One end of the first connecting plate 21 facing away from the connecting member 4 is fixedly connected with six positioning rods 26, and one end of the second connecting plate 24 is provided with six positioning grooves 23 for cooperating with the positioning rods 26. The outer surface of the corresponding positioning rod 26 is movably inserted into the inner wall of the positioning groove 23. The cooperation of the positioning groove 23 and the positioning rod 26 plays a role in facilitating the positioning when the first connecting plate 21 and the second connecting plate 24 are connected.

[0022] The outer surfaces of the first connecting plate 21 and the second connecting plate 24 are both made of sealing materials, so that the connection between the first connecting plate 21 and the second connecting plate 24 is tighter, avoiding leakage and affecting the use of the laser tube structure.

[0023] The six positioning rods 26 are distributed in a circular array, the six positioning grooves 23 are distributed in a circular array, and the outer surface shape of the positioning rod 26 is the same as the inner wall shape of the positioning groove 23, which is convenient for the positioning groove 23 to cooperate with the positioning rod 26.

[0024] The inner walls of the two first connection holes 22 and the two second connection holes 25 are both threaded, and the threads on the inner walls of the first connection hole 22 and the second connection hole 25 match the threads on the outer surface of the connection bolt 27, which is convenient for the first connection hole 22 and the second connection hole 25 to better cooperate with the connection bolt 27.

[0025] The conductive material layer 31, the thermal stability material layer 32 and the chemical stability material layer 33 are all cylindrical. The cylindrical setting is more conducive to increasing the service life of the laser tube structure.

[0026] Working principle: First, the laser diode is supplied with current through the positive electrode body 5, and the negative electrode body 6 will charge the gas in the laser tube, generating high voltage and high-frequency current, thereby exciting the atoms of the gas molecules to ionize and recombine;

[0027] When the laser tube structure is working, through the material layer assembly 3, the conductive material layer 31 makes the negative electrode body 6 more stable in guiding during use, the thermal stability material layer 32 ensures the stable operation of the laser and extends its service life, and the chemical stability material layer 33 can ensure that the laser tube maintains stable performance during long-term use, avoiding air leakage and explosion due to non-external factors;

[0028] When it is necessary to repair the negative electrode body 6 in the laser tube structure, through the connecting mechanism 2, the two connecting bolts 27 are screwed out from the corresponding first connection hole 22 and second connection hole 25, so that the first connecting plate 21 and the second connecting plate 24 are separated, thereby facilitating the removal of the negative electrode body 6 from the laser tube body 1 and facilitating the repair of the negative electrode body 6.

[0029] Meanwhile, the positioning groove 23 and the positioning rod 26 are used in cooperation to facilitate the positioning when the first connecting plate 21 and the second connecting plate 24 are connected, and regular maintenance makes the laser tube structure more stable during use.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
