[0073] The adjusting screw shaft 7 includes a threaded section 71 and a locking shaft section 72, the threaded section 71 is threadedly installed in the threaded installation groove 104, and the locking shaft section 72 is fixedly installed on the threaded section 71 , the locking shaft section 72 passes through the limit clamping hole 401 and extends into the heat exchange sleeve 4 .
[0074] The threaded installation groove 104 communicates with the limit card hole 401 , and the threaded installation groove 104 and the limit card hole 401 are on the same axis.
[0075] By movably installing the heat exchange sleeve 4 on the mounting support 1, the heat exchange sleeve 4 can be easily locked and limited in cooperation with the adjusting wire shaft 7, and the optical fiber can be locked and limited by adjusting the wire shaft 7, ensuring that For the stability of the equipment during operation, after the adjustment wire shaft 7 is removed, the disassembly of the heat exchange sleeve 4 is convenient, so as to facilitate the disassembly and maintenance of the equipment.
[0076] The split structure is more convenient for assembly and disassembly of components.
[0077] The surface of the adjusting screw shaft 7 is a stainless steel structure, and the threaded section 71 and the locking shaft section 72 are on the same axis.
[0078] The adjusting screw shaft 7 is conveniently threadedly mounted on the screw mounting groove 104 through the threaded section 71 , so that the adjusting screw shaft 7 is conveniently mounted on the mounting support 1 .
[0079] After the adjustment wire shaft 7 is installed, the locking shaft section 72 is easily inserted into the limit card hole 401 to provide a limit for the installation of the heat exchange sleeve 4, which ensures the stability of the heat exchange sleeve 4 after installation, and facilitates the heat exchange sleeve 4. It is easy to install and disassemble, and it is convenient to compress and limit the installed optical fiber.
[0080] The working principle of the second embodiment provided by the present invention:
[0081] When the heat exchange sleeve 4 needs to be installed and used, the heat exchange sleeve 4 is preferably inserted into the installation support 1, and the limit clamping hole 401 faces directly upward;
[0082] When the limit card hole 401 slides to just below the threaded installation groove 104, the adjusting screw shaft 7 is installed on the screw installation groove 104, and the locking shaft section 72 on the adjustment screw shaft 7 is inserted into the limit card hole 401 to complete the operation. The stability of the heat exchange sleeve 4 after installation;
[0083] Then install the connection joint 3, after the installation between the installation support 1 and the connection joint 3 is completed, insert the optical fiber between the installation support 1 and the connection joint 3, so that the optical fiber is butted on the Raman grating 62;
[0084] Tighten the adjusting wire shaft 7 again, and the locking shaft section 72 of the adjusting wire shaft 7 compresses and locks the installed optical fiber downward to ensure the stability of the optical fiber after installation.
[0085] The beneficial effects of the second embodiment provided by the present invention:
[0086] By movably installing the heat exchange sleeve 4 on the mounting support 1, the heat exchange sleeve 4 can be easily locked and limited in cooperation with the adjusting wire shaft 7, and the optical fiber can be locked and limited by adjusting the wire shaft 7, ensuring that For the stability of the equipment during operation, after the adjustment wire shaft 7 is removed, the disassembly of the heat exchange sleeve 4 is convenient, so as to facilitate the disassembly and maintenance of the equipment.
[0087] Optimization:
[0088] Further, see Image 6 , the optimization scheme of the output head with Raman filtering provided by this application, the difference is that the output head with Raman filtering also includes:
[0089] A limit cover 8, the limit cover 8 is fixedly installed on the connection joint 3, the limit cover 8 is a rigid plastic structure, the thickness is 4mm, one end of the limit cover 8 is rounded, and The limit cover 8 is abutted and installed on the adjusting screw shaft 7 for shielding and limiting the adjusting screw shaft 7, ensuring the stability of the adjusting screw shaft 7 after installation, and avoiding the occurrence of the adjustment screw shaft 7 during installation and use. loose, thereby improving the stability of the fiber after installation.
[0090] The working principle of the optimization scheme provided by the present invention:
[0091] When installing and using, the grating mechanism 6 is preferentially installed on the connecting joint 3;
[0092] Install the heat exchange sleeve 4 on the installation support 1, and install the adjusting wire shaft 7 between the installation support 1 and the heat exchange sleeve 4 to ensure the stability of the heat exchange sleeve 4 after installation;
[0093] Pass the optical fiber through the mounting support 1 and the heat exchange sleeve 4, and reserve a sufficient connection length of the connecting joint 3 for docking, tighten the adjusting screw shaft 7, and lock the shaft section 72 to compress the optical fiber to realize the locking of the optical fiber;
[0094] Connect the connection joint 3 to the installation support 1, after the connection joint 3 is docked with the installation support 1, the limit cover 8 covers the adjustment wire shaft 7 to form a shield and limit for the adjustment wire shaft 7, so as to ensure the adjustment wire The stability of the shaft 7 after installation can also prevent the phenomenon of misoperation after the adjustment wire shaft 7 is installed.
[0095] The beneficial effects of the optimization scheme provided by the present invention:
[0096] By installing the limit cover 8 on the connecting joint 3, after the connecting joint 3 is installed on the mounting support 1, the limit cover 8 can block and limit the installed adjusting screw shaft 7 to ensure that the adjusting screw shaft 7 is locked The stability after the equipment is prevented from loosening when the equipment is used, and the stability of the equipment during installation is maintained.
