Description

Technical Field

[0001] This utility model relates to the field of fiber laser technology, and in particular to a fiber optic interface anti-bending protection structure for fiber lasers. Background Technology

[0002] An optical fiber interface is a physical connection component used to connect optical fiber cables. Its core function is to achieve efficient transmission and coupling of optical signals. Through precise structural design, it ensures that the optical signals in the optical fiber cable can be transmitted between devices (such as switches, routers, and optical modules) with low loss and high stability.

[0003] Existing fiber optic interfaces are resistant to acids and alkalis, corrosion, and high temperatures, enabling them to operate stably in harsh environments such as humid, dusty, high-temperature (e.g., industrial workshops) or low-temperature (e.g., outdoor base stations). Although fiber optic cables have an outer sheath, the internal optical fibers and reinforcing components can deform due to fatigue under long-term stress. During cabling, these parts are squeezed, dragged, or subjected to prolonged bending, gradually accumulating stress and causing chronic bending at the connection. Current technology involves using spiral metal tubing or heat-shrink tubing at the connection to enhance bending and compression resistance, which is particularly suitable for industrial environments or frequently moved scenarios. However, the protective structure often uses fixed-size clips, sleeves, or adhesives, which can only accommodate optical fibers of a single diameter. When the fiber diameter changes, the entire protective assembly needs to be replaced, resulting in extremely poor versatility and increased costs and inventory pressure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fiber optic interface anti-bending protection structure for fiber lasers, aiming to improve the existing technology that can only adapt to optical fibers of a single diameter. When the fiber diameter changes, the entire protection assembly needs to be replaced, resulting in extremely poor versatility and increased costs and inventory pressure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fiber optic interface anti-bending protection structure for a fiber laser, including a plug, an optical fiber installed on the right end of the outer wall of the plug, a spiral metal sheath provided on the left side of the outer wall of the optical fiber, a fixing mechanism provided inside the spiral metal sheath for fixing the spiral metal sheath to the optical fiber, a connecting mechanism provided inside the plug for fixing the spiral metal sheath; the fixing mechanism includes a first groove, which is formed at the left and right ends of the outer wall of the spiral metal sheath, a clamping block is slidably connected to the inner wall of the first groove, and a driving component is provided on the outer wall of the spiral metal sheath.

[0006] As a further description of the above technical solution:

[0007] The drive assembly includes knobs, which are disposed on the left and right ends of the outer wall of the spiral metal sheath. A circular block is fixedly connected to each adjacent side of the outer wall of the two knobs. Multiple sliding grooves are equidistantly provided on the outer wall of the circular block. A sliding column is slidably connected to the inner wall of the sliding groove. The end of the sliding column is fixedly connected to the outer wall of the clamping block. A sliding ring is fixedly connected to each adjacent side of the outer wall of the two knobs. A sliding groove is provided on the left and right ends of the outer wall of the spiral metal sheath. The sliding groove is slidably connected to the sliding ring.

[0008] As a further description of the above technical solution:

[0009] The connecting mechanism includes a connecting block, which is disposed on the left end of the outer wall of the spiral metal sheath. The front and rear ends of the left side of the connecting block are fixedly connected to fixing blocks. The front and rear ends of the right side of the plug are provided with square grooves. A locking component is installed inside the plug.

[0010] As a further description of the above technical solution:

[0011] The locking component includes a second square groove, which is formed on the inner wall of the two first square grooves on opposite sides. A spring is fixedly connected to the inner wall of the second square groove, and a locking block is fixedly connected to the end of the spring. The outer walls of the two locking blocks are each provided with a locking groove on opposite sides, and the locking block engages with the locking groove.

[0012] As a further description of the above technical solution:

[0013] The grooves are equidistantly distributed on the outer wall of the spiral metal sheath, and the optical fibers are disposed on adjacent sides of the outer wall of the multiple clamping blocks.

[0014] As a further description of the above technical solution:

[0015] The fixing block is slidably connected to the first square groove, and the second square groove is slidably connected to the locking block.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the plug is provided with a sliding ring two, which is fixedly connected to the left side of the outer wall of the knob. The outer wall of the plug is provided with a sliding groove four, which is opened on the right side of the outer wall of the connecting block. The sliding ring two and the sliding groove four are slidably connected.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the plug is rotatably connected to a mounting block, and the outer wall of the mounting block is decagonal.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the optical fiber is passed through the spiral metal sheath. By rotating the knob, the optical fiber slides in the groove three of the spiral metal sheath through the sliding ring one, which drives the round block to rotate. The round block drives the sliding column to slide in the groove two. The sliding column drives the clamping block to slide along the groove one, so that multiple clamping blocks simultaneously contract and clamp the optical fiber, thereby fixing the spiral metal sheath to the optical fiber. This can adapt to optical fibers of different diameters and improve the versatility of the structure.

[0022] 2. In this utility model, the fixing block on the connecting block is aligned with the square groove of the plug and pushed in. The fixing block presses against the inclined surface of the locking block, causing the locking block to compress the spring in the square groove. When the fixing block is fully slid into the square groove, the spring rebounds and pushes the locking block into the groove of the fixing block, thereby locking the spiral metal sheath with the plug. When disassembling, the connecting block is pulled outward, causing the fixing block to press against the locking block and exit the groove. The fixing block is then slid out of the square groove. The connection is reliable through the spring preload and locking mechanism. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model provides: an anti-bending protection structure for the fiber optic interface of a fiber laser, including a plug 1, an optical fiber 2 installed on the right end of the outer wall of the plug 1, a spiral metal sheath 3 provided on the left side of the outer wall of the optical fiber 2, a fixing mechanism 4 provided inside the spiral metal sheath 3, the fixing mechanism 4 being used to fix the spiral metal sheath 3 to the optical fiber 2, and a connecting mechanism 5 provided inside the plug 1, the connecting mechanism 5 being used to fix the spiral metal sheath 3;

[0032] The fixing mechanism 4 includes a slide groove 401, which is opened at the left and right ends of the outer wall of the spiral metal sheath 3. A clamping block 402 is slidably connected to the inner wall of the slide groove 401. The sliding column 4034 drives the clamping block 402 to slide along the slide groove 401. A driving component 403 is provided on the outer wall of the spiral metal sheath 3.

[0033] The drive assembly 403 includes knobs 4031, which are located on the left and right ends of the outer wall of the spiral metal sleeve 3. Two circular blocks 4032 are fixedly connected to adjacent sides of the outer walls of the two knobs 4031. The knobs 4031 drive the circular blocks 4032 to rotate. Multiple sliding grooves 4033 are equidistantly formed on the outer walls of the circular blocks 4032. Sliding columns 4034 are slidably connected to the inner walls of the sliding grooves 4033. The circular blocks 4032 drive the sliding columns 4034 to slide within the sliding grooves 4033. The ends of the sliding columns 4034 are fixed... The outer wall of the clamping block 402 is fixedly connected. The outer walls of the two knobs 4031 are each fixedly connected to the adjacent side of the outer wall of the screw metal sheath 3. The left and right ends of the outer wall of the screw metal sheath 3 are provided with the sliding groove 4035. The sliding groove 4035 is slidably connected to the sliding ring 4036. The knob 4031 slides in the sliding groove 4035 of the screw metal sheath 3 through the sliding ring 4036. The sliding groove 401 is equidistantly distributed on the outer wall of the screw metal sheath 3. The optical fiber 2 is set on the adjacent side of the outer wall of the multiple clamping blocks 402.

[0034] Specifically, the optical fiber 2 is passed through the spiral metal sheath 3, and the knob 4031 is rotated. The knob 4031 slides in the groove 4035 of the spiral metal sheath 3 through the sliding ring 4036. The knob 4031 drives the round block 4032 to rotate, and the round block 4032 drives the sliding column 4034 to slide in the groove 4033. The sliding column 4034 drives the clamping block 402 to slide along the groove 401, so that multiple clamping blocks 402 simultaneously contract and clamp the optical fiber 2, thereby fixing the spiral metal sheath 3 to the optical fiber 2. This can accommodate optical fibers 2 of different diameters and improve the versatility of the structure.

[0035] Reference Figure 1 , Figure 2 and Figure 5 The connecting mechanism 5 includes a connecting block 501, which is located on the left end of the outer wall of the spiral metal sheath 3. The front and rear ends of the left side of the connecting block 501 are fixedly connected to fixing blocks 502. The front and rear ends of the right side of the plug 1 are provided with square grooves 503. The fixing blocks 502 on the connecting block 501 are aligned with the square grooves 503 of the plug 1 and pushed in. The plug 1 is equipped with a locking component 504.

[0036] The locking component 504 includes a second square groove 5041, which is formed on the inner wall of two first square grooves 503 on opposite sides. A spring 5042 is fixedly connected to the inner wall of the second square groove 5041, and a locking block 5043 is fixedly connected to the end of the spring 5042. The outer walls of the two fixing blocks 502 are each provided with a locking groove 5044 on opposite sides. The locking block 5043 engages with the locking groove 5044. The spring 5042 rebounds and pushes the locking block 5043 into the locking groove 5044 of the fixing block 502. The fixing block 502 is slidably connected to the first square groove 503, and the second square groove 5041 is slidably connected to the locking block 5043.

[0037] Specifically, the fixing block 502 on the connecting block 501 is precisely aligned with the square slot 503 of the plug 1 and pushed in. The inclined surface of the pressing block 5043 of the fixing block 502 compresses the spring 5042 in the square slot 5041. When the fixing block 502 is fully slid into the square slot 503, the spring 5042 rebounds and pushes the pressing block 5043 into the slot 5044 of the fixing block 502, thereby locking the spiral metal sheath 3 and the plug 1. When disassembling, simply pull the connecting block 501 outward, so that the fixing block 502 presses the pressing block 5043 out of the slot 5044, and the fixing block 502 can slide out of the square slot 503. The preload and locking force of the spring 5042 ensure the reliability of the connection.

[0038] Reference Figure 2 , Figure 4 and Figure 5The outer wall of plug 1 is provided with a sliding ring 2 6, which is fixedly connected to the left side of the outer wall of knob 4031. The outer wall of plug 1 is provided with a sliding groove 4 7, which is opened on the right side of the outer wall of connecting block 501. The sliding ring 2 6 is slidably connected to the sliding groove 4 7. When knob 4031 rotates to adjust clamp 402, the sliding ring 2 6 slides in the sliding groove 4 7, which can enhance the overall structural stability of plug 1 after it is connected to spiral metal sheath 3 and prevent shaking. The outer wall of plug 1 is rotatably connected with mounting block 8. The outer wall of mounting block 8 adopts a decagonal design. The decagonal design facilitates the installation or removal of plug 1 from external equipment and ensures accurate connection.

[0039] Specifically, when the knob 4031 rotates to adjust the clamp 402, the sliding ring 6 slides in the sliding groove 7, which can enhance the overall structural stability of the plug 1 after it is connected to the spiral metal sheath 3 and prevent shaking. The decagonal mounting block 8 is rotatably connected to the outer wall of the plug 1. The decagonal design facilitates the installation or removal of the plug 1 from external equipment and ensures accurate connection.

[0040] Working principle: The optical fiber 2 is passed through the spiral metal sheath 3. The knob 4031 is rotated. The knob 4031 slides in the groove 4035 of the spiral metal sheath 3 through the sliding ring 4036. The knob 4031 drives the round block 4032 to rotate. The round block 4032 drives the sliding column 4034 to slide in the groove 4033. The sliding column 4034 drives the clamping block 402 to slide along the groove 401. This causes multiple clamping blocks 402 to simultaneously contract and clamp the optical fiber 2, thus fixing the spiral metal sheath 3 to the optical fiber 2. This method can adapt to optical fibers 2 of different diameters, improving the versatility of the structure.

[0041] Align the fixing block 502 on the connecting block 501 with the square slot 503 of the plug 1 and push it in. The fixing block 502 presses against the inclined surface of the locking block 5043, causing the locking block 5043 to compress the spring 5042 in the square slot 5041. When the fixing block 502 is fully slid into the square slot 503, the spring 5042 rebounds and pushes the locking block 5043 into the slot 5044 of the fixing block 502, thus locking the spiral metal sheath 3 with the plug 1. When disassembling, simply pull the connecting block 501 outwards, causing the fixing block 502 to press against the locking block 5043 and exit the slot 5044, so that the fixing block 502 can slide out of the square slot 503. The preload of the spring 5042 and the locking mechanism ensure the reliability of the connection.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
