Description

Technical Field

[0001] This utility model relates to the field of fiber laser equipment, specifically to a highly reliable multi-wavelength single-mode fiber laser. Background Technology

[0002] In fields such as optical communication, fiber optic sensing, and precision measurement, multi-wavelength single-mode fiber lasers, capable of simultaneously outputting multiple stable single-mode laser wavelengths, have become core equipment supporting technologies such as high-capacity communication transmission and distributed sensing and monitoring. Through wavelength division multiplexing (WDM) technology, they can significantly improve fiber optic transmission efficiency, or achieve high-precision sensing of complex physical quantities through multi-wavelength parallel measurement, making them widely used in industrial production, scientific research experiments, and other scenarios.

[0003] The fiber optic interface of a laser is constantly exposed to the external environment, making it susceptible to optical performance degradation and even interface wear due to the intrusion of impurities such as dust, moisture, and oil. Traditional protective structures often use simple plastic caps or rubber plugs. After removal, the rubber plugs are easily misplaced by operators, causing dust to accumulate at the connection between the rubber plug and the interface. When reused, this dust can be introduced into the interface, severely affecting the long-term stability of the laser.

[0004] Therefore, it is necessary to invent a highly reliable multi-wavelength single-mode fiber laser to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly reliable multi-wavelength single-mode fiber laser. By setting up a sealing component, the interface is double-sealed and protected. At the same time, the sealing component and the kit form a linked storage structure, which can solve the problems in the prior art that "the rubber plug in the traditional protective structure is easy to lose, easy to get dusty after removal, and contaminates the interface when reused, resulting in the attenuation of the laser's optical performance and affecting its long-term stability".

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly reliable multi-wavelength single-mode fiber laser, comprising;

[0007] A sealing assembly is disposed on the outside of the interface of the fiber laser, and a support assembly and a limiting assembly are respectively disposed on the upper part of the fiber laser. The sealing assembly includes a fixing ring, which is sleeved on the outside of the interface of the fiber laser. A kit is fixedly connected to the front side of the fixing ring by a rubber strip. An annular groove is opened on the inner wall of the rear part of the kit, and a slot is opened on the front side of the kit. A sealing member is inserted into the inner wall of the slot.

[0008] Preferably, the support assembly includes a slide rail, which is fixedly connected to the upper part of the fiber laser. The slide rail is cross-shaped, and multiple sets of sliders are slidably connected to the inner wall of the slide rail. A support rod is fixedly connected to the upper part of the slider, and the support rod is L-shaped.

[0009] Preferably, the limiting component includes a base, which is slidably connected to the inner wall of the slide rail. A top cover is fixedly installed on the upper part of the base. A limiting component is installed on the inner wall of the base. A slot is provided through the inner wall of the slide rail. The lower part of the limiting component is inserted into the inner wall of the slot. The upper part of the limiting component is elastically connected to the top cover through an elastic component.

[0010] Preferably, the front side of the closure is recessed, and a pull ring is rotatably connected to the inner wall of the recess on the front side of the closure. The closure is made of metal.

[0011] Preferably, the kit and retaining ring are made of rubber.

[0012] Preferably, the limiting member extends to the outer side of the base on the side near the center of the slide rail.

[0013] Preferably, the elastic element is a spring, with one end of the spring contacting the inner wall of the upper cover and the other end of the spring contacting the upper part of the limiting element.

[0014] Preferably, the outer side of the closure is provided with an annular protrusion.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The sealing component of this utility model is tightly fitted to the outside of the laser interface by a rubber fixing ring. The elastic deformation of the rubber is used to isolate the interface from the outside. When the interface is needed, the metal sealing component is removed and inserted into the back of the kit. The annular protrusion on its outer side enhances the fit with the kit, which can effectively prevent dust, moisture and other impurities from entering the kit. This reduces the impact of the kit on the interface during use, avoids contamination or corrosion of optical components, and balances sealing performance with ease of operation, ensuring long-term stable operation of the laser interface.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1 , Figure 2 and Figure 5 The high-reliability multi-wavelength single-mode fiber laser shown includes a closed assembly 1, specifically;

[0028] The sealing component 1 is located on the outside of the interface of the fiber laser, and the upper part of the fiber laser is provided with a support component 2 and a limiting component 3. The sealing component 1 includes a fixing ring 11, which is sleeved on the outside of the interface of the fiber laser to fix the sealing component 1 on the outside of the interface. It is suspended when not in use to prevent loss. The front side of the fixing ring 11 is fixedly connected to the kit 12 by a rubber strip to seal the interface of the fiber laser and prevent dust and impurities from entering. The inner wall of the rear part of the kit 12 has an annular groove for installing the sealing component 13. The surface of the sealing component 13 is polished to reduce dust adhesion. The front side of the kit 12 has a slot 15, which serves as the installation position for the sealing component 13 when the kit 12 is in use. The inner wall of the slot 15 is inserted into the sealing component 13. When the interface is in use, the sealing component 13 is tightly inserted into the annular groove on the inner wall of the rear part of the kit 12 through the annular protrusion to achieve complete sealing of the kit 12, blocking impurities from entering the kit 12 and reducing the impact on the interface. The kit 12 and the fixing ring 11 are made of rubber, and the outer side of the sealing component 13 has an annular protrusion.

[0029] like Figure 3 - Figure 5 As shown, the support component 2 includes a slide rail 21, which is fixedly connected to the upper part of the fiber laser. The slide rail 21 is cross-shaped, providing a sliding track for the slider 22 and the limiting component 3. Its cross-shaped design allows the components to be adjusted in multiple directions in the horizontal direction to adapt to different installation requirements. Multiple sets of sliders 22 are slidably connected to the inner wall of the slide rail 21. A support rod 23 is fixedly connected to the upper part of the slider 22. The support rod 23 is L-shaped. The slider 22 and the support rod 23 support each other and are used to fix the wound optical fiber. The L-shaped design can stably support the optical fiber and prevent it from slipping.

[0030] like Figure 3 - Figure 5As shown, the limiting component 3 includes a base 31, which is slidably connected to the inner wall of the slide rail 21, providing a mounting carrier for components such as the upper cover 32 and the limiting member 33. It can move along the slide rail 21 with the slider 22 to achieve overall position adjustment. The upper cover 32 is fixedly installed on the upper part of the base 31, enclosing the internal space of the base 31, protecting the limiting member 33 and the elastic member 34, and providing an upper support point for the elastic member 34. The limiting member 33 is installed on the inner wall of the base 31, and the side of the limiting member 33 closest to the center of the slide rail 21 extends to the base 31. On the outer side, for easy movement of the limiting member 33 by the operator, a slot 35 is provided through the inner wall of the slide rail 21 to provide an insertion position for the limiting member 33. The lower part of the limiting member 33 is inserted into the inner wall of the slot 35, and the upper part of the limiting member 33 is elastically connected to the upper cover 32 through an elastic member 34. The elastic member 34 is a spring, with one end of the spring contacting the inner wall of the upper cover 32 and the other end of the spring contacting the upper part of the limiting member 33, providing continuous downward pressure to the limiting member 33 to ensure that its lower part is stably inserted into the slot 35, thereby enhancing the reliability of the limiting. The front side of the sealing member 13 is recessed, and a pull ring 14 is rotatably connected to the inner wall of the recess on the front side of the sealing member 13, making it convenient for the operator to pull the sealing member 13. The sealing member 13 is made of metal.

[0031] The working principle of this utility model is as follows: In terms of interface protection, the sealing component 1 is tightly fitted onto the outside of the laser interface by a rubber retaining ring 11, and the front fitting 12 forms an initial seal with the interface through elastic deformation. When the interface is not in use, the metal sealing component 13 inserts into the slot 15 on the front of the fitting 12 through the outer annular protrusion, achieving complete sealing of the interface and preventing dust and moisture from entering.

[0032] When the interface is needed, pull it out through the pull ring 14 at the front recess of the closure 13, and then insert the closure 13 in reverse into the annular groove at the rear of the kit 12. The fit between the annular protrusion and the groove seals the inside of the kit 12 again, preventing impurities from entering the unused kit 12 and ensuring the interface is clean.

[0033] In terms of fiber support and adjustment, the cross-shaped slide rail 21 on the upper part of the fiber laser provides a moving track for the support component 2 and the limiting component 3. The L-shaped support rod 23 slides along the slide rail 21 through the slider 22, and the support point can be adjusted according to the size and position requirements of the fiber winding to achieve stable support for the fiber.

[0034] During the adjustment process, the base 31 of the limiting component 3 moves synchronously with the slider 22, and the elastic element 34 always applies downward pressure to the limiting component 33, so that its lower part is stably inserted into the slot 35 of the slide rail 21, fixing the position of the support rod 23. If readjustment is required, simply pull up the extension part of the limiting component 33 on the outside of the base 31 to disengage it from the slot 35, which will unlock and move it to a new position. After being released, the limiting component 33 will be snapped back into the corresponding slot 35 under the action of the spring, completing the quick fixation. When fixing the optical fiber, only two sets of limiting components 3 need to be moved to achieve quick disassembly of the optical fiber.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
