Description

Technical Field

[0001] This utility model relates to the technical field of fiber optic auxiliary connection equipment, specifically a laser fiber anti-bending auxiliary connection device. Background Technology

[0002] Due to its inherent strength, optical fiber cannot be bent at excessively large angles. Exceeding a certain limit can easily cause fiber optic bending, which may impair optical signal transmission and affect laser performance. Therefore, it is necessary to support, fix, and protect the optical fiber to ensure that it remains in good condition during connection and to guarantee the stable and reliable operation of the laser system.

[0003] Existing fiber optic auxiliary connection solutions typically involve bundling the fiber to restrict its movement within a certain range. However, this approach is ineffective in dealing with compression caused by the fiber's inherent length limitations. Furthermore, the bundling method makes the fiber more prone to bending at the bundling points when subjected to pulling, which can be counterproductive and inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary connection device for preventing laser fiber bending. This device has the advantage of effectively preventing irreversible damage to the optical fiber due to bending or compression. It solves the problem that existing optical fiber auxiliary connection solutions usually involve binding the fiber to restrict its movement within a certain range. However, this method cannot effectively cope with compression caused by the fiber's own length limitations, and the binding method makes the binding points more prone to bending when subjected to pulling.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A laser fiber anti-bending auxiliary connection device includes a bending tube, both ends of which are connected to protective straight tubes. An elastic pressing component capable of providing extreme bending alarm is connected between the two protective straight tubes. An adjustment component is provided inside the elastic pressing component to adjust the gap between the two protective straight tubes. Both ends of the elastic pressing component are fixedly and slidably connected to the two protective straight tubes, respectively. A tension buffer component is provided on the side of the protective straight tube that is fixedly connected to the elastic pressing component.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the curved tube is a flexible tube, and the protective straight tube is composed of a rigid pipe and an internal buffer sleeve. The inner diameter of the curved tube and the protective straight tube is adapted to the outer diameter of the laser fiber.

[0010] Furthermore, the elastic pressing component includes a connecting sleeve that is fixedly connected to one of the protective straight tubes and slidably connected to the adjusting component on its inner side. A support spring for supporting the protective straight tubes on both sides is fixedly connected inside the connecting sleeve. A support rod that is slidably connected to the adjusting component on its outer side and slidably connected to the outer side of the other protective straight tube is fixedly connected to the other end of the support spring.

[0011] Furthermore, the end of the support rod is C-shaped, and the inner side of the end of the support rod is provided with sliding balls that slide in contact with the outside of the protective straight tube.

[0012] Furthermore, the adjusting assembly includes a restrictive sliding ring slidably connected inside the connecting sleeve. The outer thread of the restrictive sliding ring is connected to a fastening pin that contacts the connecting sleeve and creates a restriction. One end of the support rod located inside the connecting sleeve passes through the restrictive sliding ring and is provided with a pushing plate at its end. The two sides of the pushing plate contact the restrictive sliding ring and the support spring, respectively.

[0013] Furthermore, the buffer assembly includes a buffer sleeve disposed at the end of the protective straight pipe. The buffer sleeve is flat and has a diamond-shaped cavity inside. Trigger-type indicator devices are disposed on the front and rear walls of the inner cavity of the buffer sleeve.

[0014] This utility model provides an auxiliary connection device for preventing laser fiber bending. By setting up a protective straight tube, the fiber can be inserted through the protective straight tube during fiber installation, and then extended after passing through the protective straight tube, the bending tube, and the other protective straight tube. At this time, the adjustment component can be adjusted according to the installation status of both ends of the fiber, so that the relative movement distance between the two protective straight tubes is limited. At the same time, the redundant bending tube can ensure that the two protective straight tubes can move alternately. During the alternate movement, the support rod provides a connection to prevent the displacement direction from deflecting, providing more movement options for the fiber.

[0015] Meanwhile, when the optical fiber is compressed, an axial compressive force is applied to both ends, causing them to begin to compress inward. At this time, the buffer sleeve can easily cause the optical fiber to deform inside, thereby reducing the impact of compression at both ends. When the compression at both ends continues, causing the optical fiber deformation to exceed a certain threshold, a trigger indicator will be activated to alert the outside world, thus preventing excessive compression from causing irreversible damage to the optical fiber.

[0016] In summary, this device has the advantage of effectively preventing irreversible damage to optical fibers caused by bending or compression. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides an auxiliary connection device for preventing the bending of laser optical fibers, including a bending tube 1, with protective straight tubes 2 connected to both ends of the bending tube 1. An elastic pressing component 3 capable of providing extreme bending alarm is connected between the two protective straight tubes 2. An adjusting component 4 is provided inside the elastic pressing component 3 to adjust the gap between the two protective straight tubes 2. The two ends of the elastic pressing component 3 are fixedly and slidably connected to the two protective straight tubes 2, respectively. A tension buffer component 5 is provided on the side of the protective straight tube 2 that is fixedly connected to the elastic pressing component 3.

[0025] Furthermore, the curved tube 1 is a flexible tube, and the protective straight tube 2 is composed of a rigid pipe and an internal buffer sleeve. The inner diameter of the curved tube 1 and the protective straight tube 2 is adapted to the outer diameter of the laser fiber.

[0026] Redundancy is provided at the connection points between the two ends of the bent tube 1 and the protective straight tube 2. When the protective straight tubes 2 on both sides approach their limits, the relative bending angle between the bent tube 1 and the protective straight tube 2 is less than the bending damage angle of the optical fiber.

[0027] Furthermore, the elastic pressing component 3 includes a connecting sleeve 31 that is fixedly connected to one of the protective straight tubes 2 and slidably connected to the adjusting component 4 on its inner side. The connecting sleeve 31 is fixedly connected to a support spring 32 for supporting the protective straight tubes 2 on both sides. The other end of the support spring 32 is fixedly connected to a support rod 33 that is slidably connected to the adjusting component 4 on its outer side and slidably connected to the outer side of the other protective straight tube 2 on its end.

[0028] Furthermore, the end of the support rod 33 is C-shaped, and the inner side of the end of the support rod 33 is provided with sliding balls that slide in contact with the outside of the protective straight tube 2.

[0029] When the elastic pressing component 3 is in operation, it is supported by the support spring 32 and the support rod 33, so that the two protective straight tubes 2 on both sides always have elastic force to keep them away from each other, preventing abnormal bending of the two protective straight tubes 2.

[0030] Furthermore, the adjusting component 4 includes a restrictive sliding ring 41 slidably connected inside the connecting sleeve 31. The outer thread of the restrictive sliding ring 41 is connected to a fastening pin 42 that contacts the connecting sleeve 31 and creates a restriction. One end of the support rod 33 located inside the connecting sleeve 31 passes through the restrictive sliding ring 41 and is provided with a pushing plate at its end. The two sides of the pushing plate contact the restrictive sliding ring 41 and the support spring 32, respectively.

[0031] Furthermore, the buffer assembly 5 includes a buffer sleeve 51 disposed at the end of the protective straight pipe 2. The buffer sleeve 51 is flat and has a diamond-shaped cavity inside. Trigger-type indicator 52 is disposed on both the front and rear walls of the inner cavity of the buffer sleeve 51.

[0032] The trigger-type indicator 52 can consist of two parts: a pressure sensor and an alarm. The pressure sensor controls the alarm to generate an alert.
