Description

Technical Field

[0001] The present application relates to the field of pressure-resistant housings, and in particular to a pressure-resistant housing structure and a fiber laser. Background Art

[0002] Fiber laser refers to a laser that uses rare earth-doped glass fiber as a gain medium. Fiber laser can be developed based on fiber amplifiers: under the action of pump light, high power density is easily formed in the optical fiber, causing a "particle number inversion" in the laser energy level of the laser working material. When a positive feedback loop is appropriately added (forming a resonant cavity), laser oscillation output can be formed.

[0003] The fiber laser consists of an external shell and internal components. The external shell is used to protect the internal components to prevent them from being affected by the external environment. However, the existing external shell has a single structure, which makes it have low pressure resistance. When the external shell is subjected to external pressure, it is easy to be damaged, which will further affect the operation of the internal components. For this reason, we propose a pressure-resistant shell structure and a fiber laser. Utility Model Content

The two support rings 50 are respectively in contact with the bottom of the bottom shell 10 and the bottom of the box cover 20 to achieve the support purpose.

It should be noted that by arranging a plurality of reinforcing strips 110, the structural strength of the bottom shell 10 can be achieved to improve its compression resistance. At the same time, the four corners of the bottom shell 10 are concavely arranged, which can further improve the structural strength of the bottom shell 10.

[0025] See also Figure 4The pulling mechanism 40 includes two steel wires 410 that are slidably penetrate the support block 30. One ends of the two steel wires 410 are respectively connected to the two support rings 50, and the other ends are fixedly connected to the connecting blocks 420. The two connecting blocks 420 are both slidably connected to the support block 30, and the same spring 430 is connected therebetween. In the specific setting, the four steel wires 410 are connected to the same support ring 50, so that when the support ring 50 is under pressure, the four steel wires 410 will be pulled at the same time, and the steel wires 410 will pull the springs 430 through the connecting blocks 420, thereby improving the pressure resistance of the shell.

[0026] See also Figure 5 One end of the steel wire 410 is fixedly connected to an insertion rod 440, which is T-shaped and slides through the support ring 50. It should be noted that a through hole is provided on the support ring 50, so that one end of the insertion rod 440 can be inserted into the through hole, thereby facilitating the connection between the support ring 50 and the four steel wires 410. Further, it is convenient to disassemble and assemble the support ring 50 to avoid affecting the installation of the components. In addition, a number of pads are installed at the bottom of the bottom shell 10, and the height of the pads is higher than the support ring 50 at the bottom, so that the components can be installed on the pads.
