Description

Technical Field

[0001] This utility model belongs to the technical field of light-emitting flange protection covers, specifically relating to a light-emitting flange protection cover for a narrow-linewidth NPRO solid-state laser. Background Technology

[0002] The narrow-linewidth NPRO solid-state laser has an output power of 350mW, an output wavelength of 1064nm (invisible laser), a laser safety level of Class 3, and uses a fiber optic flange to output the laser.

[0003] In the application of narrow linewidth NPRO solid-state lasers, the protection of the output flange is a key aspect to ensure the stability of laser performance.

[0004] Currently, existing protection solutions for the output flange have significant shortcomings: on the one hand, when the laser is subjected to collisions during transportation or use, the output flange lacks an effective physical protection structure and is easily damaged; on the other hand, dust in the environment can easily contaminate the fiber optic flange at the output port, leading to a decrease in output power. Utility Model Content

[0005] The purpose of this invention is to provide a protective cover for the output flange of a narrow linewidth NPRO solid-state laser. This cover can form a protective shield on the outside of the output flange to protect it, reducing damage to the output flange caused by collisions during laser transportation or use, reducing dust contamination of the output flange at the output port, and reducing the decrease in output power caused by dust contamination of the output flange.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A protective cover for the output flange of a narrow linewidth NPRO solid-state laser includes a flange cover base plate, and a flange cover body is hinged to the outer side of the flange cover base plate.

[0008] The flange cover body is also provided with a locking component, which includes a threaded post. A threaded hole is opened on the side of the flange cover body, and the threaded post is threadedly connected inside the threaded hole.

[0009] Furthermore, the threaded column has an internal mounting hole, and a return spring is installed inside the mounting hole. One end of the return spring is fixedly connected to a top column.

[0010] Furthermore, the flange cover base plate has positioning holes on its side, and the end of the top column has a hemispherical structure.

[0011] Furthermore, a connecting block one is fixedly connected to one side of the flange protection cover base plate, and a connecting block two is fixedly connected to one side of the flange protection cover body. A gap groove is provided on the assembly of the flange protection cover body and the connecting block two, which is in clearance fit with the connecting block one. The connecting block one and the connecting block two are rotatably connected by a cylindrical pin and a needle roller.

[0012] Furthermore, the cylindrical pin roller is made of bearing steel.

[0013] Furthermore, a sealing ring mounting groove is formed on the circumferential side of the flange protective cover base plate, and a sealing ring body is installed inside the sealing ring mounting groove.

[0014] Furthermore, an air guide cavity is formed inside the sealing ring body, and an air pump is provided with the sealing ring body. The air pump is connected to the air guide cavity inside the sealing ring body through an air guide pipe.

[0015] Furthermore, the inner wall of the flange protective cover body is provided with a groove that is opposite to the sealing ring mounting groove.

[0016] Furthermore, a rubber sealing gasket is fixedly connected to the inner wall of the flange protective cover body.

[0017] The technical effects achieved by this utility model are as follows:

[0018] This utility model discloses a protective cover for the output flange of a narrow-linewidth NPRO solid-state laser. Through the flange cover base plate and the flange cover body, a protective cover is formed on the outside of the output flange to protect it. This reduces the phenomenon of damage to the output flange caused by collisions during laser transportation or use, and also reduces the phenomenon of dust contamination of the output flange at the output port in the environment, thus reducing the phenomenon of reduced output power due to dust contamination of the output flange.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-4 As shown, a protective cover for the output flange of a narrow linewidth NPRO solid-state laser includes a flange protective cover base plate 3 that is fixedly connected to the front side of the laser front panel 1 by screws. The flange protective cover base plate 3 is located outside the output flange 2, so that the protective cover can cover the output flange 2 inside and protect the output flange 2.

[0027] The flange protection cover body 4 is hinged to the outside of the flange protection cover base plate 3. The maximum opening angle of the flange protection cover body 4 is 135°. The flange protection cover body 4 can be rotated to cover the outside of the flange protection cover base plate 3, realizing the flip-closure of the flange protection cover body 4, thereby forming the first sealing protection structure on the outside of the light-emitting flange 2, protecting the light-emitting flange 2, and reducing the pollution of the light-emitting flange 2 by dust in the environment.

[0028] like Figures 2-4 As shown, in order to lock the flange protective cover body 4 after rotation and closing, a locking component can also be provided on the flange protective cover body 4. The locking component includes a threaded post 6. A threaded hole 5 is opened on the side of the flange protective cover body 4. The threaded post 6 is threaded into the threaded hole 5. By rotating the threaded post 6, it can be controlled whether the threaded post 6 abuts against the flange protective cover base plate 3. When the threaded post 6 abuts against the flange protective cover base plate 3, the flange protective cover body 4 can be locked.

[0029] The threaded column 6 can have an installation hole 16 inside, and a return spring 17 is installed inside the installation hole 16. One end of the return spring 17 is fixedly connected to a top column 18. At this time, when the threaded column 6 is not in direct contact with the flange cover base plate 3, the return spring 17 applies an elastic thrust to the top column 18, which makes the top column 18 abut against the flange cover base plate 3, forming an elastic locking force between the flange cover base plate 3 and the flange cover body 4. Thus, after the flange cover body 4 is rotated and closed, it can be directly locked, which facilitates the opening and closing of the flange cover body 4.

[0030] To improve locking stability, a positioning hole 7 is provided on the side of the flange protection cover base plate 3, and the end of the top post 18 is a hemispherical structure. When the hemispherical structure of the top post 18 enters the positioning hole 7, the locking stability between the flange protection cover base plate 3 and the flange protection cover body 4 can be improved. Since the end of the top post 18 is a hemispherical structure, a pulling force is applied to the flange protection cover body 4. When the pulling force is greater than the pushing force applied to the top post 18 by the return spring 17, the top post 18 can be squeezed out from the positioning hole 7, thus completing the unlocking.

[0031] Specifically, such as Figure 1-2 As shown, one of the connection structures between the flange cover base plate 3 and the flange cover body 4 is disclosed here. A connecting block 1 8 is fixedly connected to one side of the flange cover base plate 3, and a connecting block 2 10 is fixedly connected to one side of the flange cover body 4. A clearance groove 19 that is clearance-fitted with the connecting block 1 8 is provided on the assembly of the flange cover body 4 and the connecting block 2 10. The connecting block 1 8 and the connecting block 2 10 are rotatably connected by a cylindrical pin and needle roller 9.

[0032] The cylindrical pin needle roller 9 can be made of bearing steel, which has a robust structure and wear-resistant properties, greatly increasing the number of opening and closing cycles.

[0033] like Figures 1-3 As shown, a sealing ring mounting groove 12 is formed on the periphery of the flange protection cover base plate 3. A sealing ring body 13 is installed inside the sealing ring mounting groove 12. The sealing ring body 13 can be made of rubber or latex. The sealing ring body 13 forms a second sealing protection structure between the flange protection cover base plate 3 and the flange protection cover body 4, reducing the phenomenon of dust entering the interior of the light-emitting flange 2 and coming into contact with the light-emitting flange 2 through the gap between the flange protection cover base plate 3 and the flange protection cover body 4.

[0034] Meanwhile, an air guide cavity can be formed inside the sealing ring body 13. The sealing ring body 13 is equipped with an air pump 11, which is connected to the air guide cavity inside the sealing ring body 13 via an air guide pipe. Figure 1As shown, the air pump 11 can be fixedly connected to the front panel 1 of the laser, and the air duct is built into the front panel 1 of the laser. After the flange protective cover body 4 is closed, the air pump 11 inflates the air duct inside the sealing ring body 13, which in turn expands the sealing ring body 13 and fills the gap between the flange protective cover base plate 3 and the flange protective cover base plate 3, thereby improving the sealing performance.

[0035] The inner wall of the flange cover body 4 can be provided with a groove 15 that is opposite to the sealing ring mounting groove 12. When the sealing ring body 13 extends into the groove 15, the shape of the gap between the sealing ring body 13 and the flange cover body 4 can be changed to improve the sealing performance.

[0036] like Figures 1-2 As shown, a rubber sealing gasket 14 can be fixedly connected to the inner wall of the flange protection cover body 4. When the flange protection cover body 4 is rotated to the closed position, the rubber sealing gasket 14 and the flange protection cover base plate 3 abut against each other, forming a third sealing protection structure between the flange protection cover base plate 3 and the flange protection cover body 4.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
