Description

Technical Field

[0001] This utility model relates to the field of optical fiber corrosion technology, specifically to a fixture for optical fiber corrosion. Background Technology

[0002] Optical fibers generally consist of a core, cladding, and coating. Light enters the fiber at a specific incident angle and undergoes total emission between the fiber and the cladding, allowing it to propagate within the fiber. In the fabrication of some core fiber optic devices, considering structural rationality and manufacturing process stability, it is necessary to partially remove the fiber cladding according to design requirements. Currently, fiber etching machines are mainly used for etching. These machines require fixtures, but existing fixtures have some shortcomings. To meet market needs, a new type of fixture for fiber etching is required.

[0003] Existing clamps lack flexibility in adjusting the etching position of the optical fiber, and their installation and use are inconvenient and cumbersome. This makes it difficult for users to install the clamp body in the designated position on the fiber etching machine, resulting in inconvenience. Furthermore, existing clamps typically lack the function of adjusting the etching position, preventing the support position from being adjusted according to the required fiber etching length, thus reducing the etching effect on the fiber. In addition, the overall sealing performance of existing clamps is insufficient, making it impossible to seal the clamp body and the sealing cap, which can easily lead to hydrofluoric acid solution leakage during use.

After the support base is adjusted to the desired position, the guide block drives the rubber clip to automatically engage inside the corresponding arc-shaped groove. The engagement between the rubber clip and the arc-shaped groove fixes the support base inside the etching groove. This allows the support base to be adjusted to the required position according to the required etching length of the optical fiber, ensuring better support for the bottom of the optical fiber. This realizes the function of adjusting the etching position of the clamp, allowing the position of the support base to be adjusted according to the required etching length of the optical fiber, resulting in a better etching effect on the optical fiber during use.

[0016] 3. With a highly sealing mechanism, the user places the natural rubber plugs on the surface of the clamp body and pushes them, causing them to be inserted into the groove. At this point, the rubber plugs move the rubber protrusions to contact the inner wall of the groove, and the natural rubber plugs automatically engage with the clamp body. This seals the natural rubber plugs on the surface of the clamp body, and the combined action of the natural rubber plugs and the rubber plugs seals the fiber optic cable and the groove, achieving a highly sealing function. This ensures a seal between the clamp body and the sealing cover during use, preventing leakage of hydrofluoric acid solution. Attached Figure Description

[0025] The structure of the optical fiber etching fixture provided by this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the fixture includes a fixture body 1, a sealing cover 103 on the surface of the fixture body 1, the sealing cover 103 and the surface of the fixture body 1 being rotatably engaged; a fixing block 108 is installed on the inner wall of the sealing cover 103, the fixing block 108 and the surface of the fixture body 1 being engaged; an etching groove 101 is formed inside the fixture body 1, a support base 102 is provided inside the etching groove 101, the support base 102 and the inner wall of the etching groove 101 are slidably engaged; the surface of the fixture body 1 is provided with equally spaced grooves 112, the surface of the support base 102 is provided with equally spaced holding slots 105, and optical fibers are placed on the surface of the holding slots 105. The main body 104 has one end passing through the groove 112 and extending to the outside of the clamp body 1. The surface of the support base 102 is equipped with pointers 106. The surface of the clamp body 1 is equipped with a liquid inlet pipe 107, one end of which extends into the interior of the etching tank 101. The surface of the clamp body 1 is equipped with a liquid outlet pipe 109, one end of which extends into the interior of the etching tank 101. The surface of the clamp body 1 is equipped with a water inlet pipe 111, one end of which extends into the interior of the etching tank 101. The surface of the clamp body 1 is equipped with a drain pipe 110, one end of which extends into the interior of the etching tank 101.

[0026] Furthermore, such as Figure 2 and Figure 4 As shown, a high-sealing mechanism 2 is provided on the surface of the clamp body 1 and the inner wall of the groove 112. The high-sealing mechanism 2 is composed of natural rubber plugs 21, clips 22, rubber protrusions 23 and rubber plugs 24. Natural rubber plugs 21 with equal spacing are provided on the surface of the clamp body 1. The inner wall of the natural rubber plugs 21 is in contact with the surface of the clamp body 1. Rubber plugs 24 are installed on the surface of the natural rubber plugs 21. One end of the rubber plugs 24 extends into the interior of the groove 112. Rubber protrusions 23 are installed on the surface of the rubber plugs 24. The surface of the rubber protrusions 23 is in contact with the inner wall of the groove 112. The natural rubber plugs 21 are sleeved on the surface of the optical fiber body 104. Clips 22 are installed on the inner wall of the natural rubber plugs 21. The clips 22 are engaged with the surface of the clamp body 1.

[0027] During implementation, the user places the natural rubber plugs 21 on the surface of the clamp body 1, and then pushes the natural rubber plugs 21 so that the natural rubber plugs 21 drive the rubber plugs 24 into the groove 112. At this time, the rubber plugs 24 drive the rubber protrusions 23 to move to contact the inner wall of the groove 112. The natural rubber plugs 21 drive the clips 22 to automatically clip onto the surface of the clamp body 1, thereby installing the natural rubber plugs 21 on the surface of the clamp body 1. Under the joint action of the natural rubber plugs 21 and the rubber plugs 24, the optical fiber body 104 and the groove 112 are sealed to achieve the high sealing function of the clamp.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, the inner walls of the fixture body 1 and the corrosion tank 101 are provided with an adjustment position mechanism 3. The adjustment position mechanism 3 consists of a guide groove 31, an arc groove 32, a fixing groove 33, a scale 34, a rubber clamp 35, and a guide block 36. The inner walls on both sides of the fixture body 1 are provided with fixing grooves 33, which slide in cooperation with the surface of the support base 102. The inner walls of the corrosion tank 101 are provided with guide grooves 31. The surface of the support base 102 at the bottom position is provided with guide blocks 36, which slide in cooperation with the inner walls of the guide grooves 31. The inner walls of the guide grooves 31 are provided with arc grooves 32 at equal intervals. The surface of the guide blocks 36 is provided with rubber clamps 35, which engage with the inner walls of the arc grooves 32. The surface of the fixture body 1 is provided with a scale 34.

[0029] During implementation, the support base 102 drives the guide block 36 to slide inside the guide groove 31. Under the combined action of the guide groove 31 and the guide block 36, the support base 102 is guided. When adjusting the support base 102, the user precisely adjusts the position of the support base 102 according to the scale position pointed to by the pointer 106 on the scale 34. After the support base 102 is adjusted to the required position, the guide block 36 drives the rubber clip 35 to automatically lock into the corresponding arc groove 32. Under the locking action of the rubber clip 35 and the arc groove 32, the support base 102 is fixed inside the etching groove 101. This allows the support base 102 to be adjusted to the required position according to the required etching length of the optical fiber body 104, ensuring that the support base 102 can better support the bottom of the optical fiber body 104, thereby realizing the function of adjusting the etching position of the clamp.

[0030] Furthermore, such as Figure 3 and Figure 6As shown, both sides of the fixture body 1 are provided with a convenient installation mechanism 4. The convenient installation mechanism 4 consists of a mounting block 41, a groove 42, a fastening stud 43, and an anti-loosening sleeve 44. Mounting blocks 41 are installed on both sides of the fixture body 1. A groove 42 is opened on the surface of the mounting block 41. An anti-loosening sleeve 44 is installed on the inner wall of the groove 42. The fastening stud 43 is threadedly connected to the surface of the anti-loosening sleeve 44. One end of the fastening stud 43 passes through the anti-loosening sleeve 44 and the mounting block 41 in sequence and extends to the bottom of the mounting block 41.

[0031] During implementation, the user tightens the fastening stud 43 on the surface of the groove 42. With the threaded engagement of the fastening stud 43 and the anti-loosening sleeve 44, the mounting block 41 is installed on the surface of the corrosion machine, thereby installing the fixture body 1 on the surface of the corrosion machine for use. With the threaded engagement of the anti-loosening sleeve 44 and the fastening stud 43, the fixture body 1 is prevented from loosening during use, thus achieving the function of easy installation of the fixture.

[0032] Working principle: In use, first place the clamp body 1 at the designated position on the external fiber optic etching machine. The user tightens the fastening stud 43 on the surface of the groove 42. With the threaded engagement of the fastening stud 43 and the anti-loosening sleeve 44, the mounting block 41 is installed on the surface of the etching machine, thus installing the clamp body 1 on the surface of the etching machine for use. The threaded engagement of the anti-loosening sleeve 44 and the fastening stud 43 prevents the clamp body 1 from loosening during use, thus achieving the function of easy installation of the clamp. This makes it convenient for the user to install the clamp body 1 at the designated position on the fiber optic etching machine, making the clamp more convenient to use.

[0033] Subsequently, the user places the optical fiber to be etched on the surface of the support base 102 inside the etching tank 101, so that the optical fiber is placed inside the holding tank 105. At this time, the other end of the optical fiber body 104 extends through the groove 112 to the outside of the clamp body 1. The user adjusts the position of the support base 102 according to the position of the optical fiber body 104 placed on the surface of the support base 102, so that the support base 102 can drive the optical fiber body 104 to move, and the length of the optical fiber body 104 moving into the etching tank 101 can be adjusted. After the user places the optical fiber body 104 on the surface of the support base 102, the user rotates the sealing cover 103 on the surface of the clamp body 1, so that the sealing cover 103 covers the surface of the clamp body 1. The hydrofluoric acid solution inside the etching tank 101 is sealed by the sealing cap 103. Then, the hydrofluoric acid solution enters the inside of the etching tank 101 through the inlet pipe 107 to etch the optical fiber body 104 inside the etching tank 101. After the optical fiber body 104 inside the etching tank 101 is etched, the hydrofluoric acid solution inside the etching tank 101 is discharged into a designated tank for storage by the outlet pipe 109 for subsequent processing. Cleaning water is drawn into the inside of the etching tank 101 through the water inlet pipe 111 to rinse the inside of the etching tank 101 and the surface of the support base 102. After rinsing, the wastewater after rinsing is discharged from the inside of the etching tank 101 by the drain pipe 110.

[0034] Subsequently, the user pulls the support base 102, causing the support base 102 to slide the guide block 36 inside the guide groove 31. The guide groove 31 and the guide block 36 work together to guide the support base 102. When adjusting the support base 102, the user precisely adjusts its position according to the scale position indicated by the pointer 106 on the scale 34. Once the support base 102 is adjusted to the desired position, the guide block 36 causes the rubber locking block 35 to automatically engage inside the corresponding arc-shaped groove 32. The clamping action of 35 and arc-shaped groove 32 fixes the support base 102 inside the etching groove 101, so that the support base 102 can be adjusted to the required position according to the etching length of the optical fiber body 104. This ensures that the support base 102 can better support the bottom of the optical fiber body 104, thereby realizing the function of adjusting the etching position of the clamp. This allows the position of the support base 102 to be adjusted according to the etching length of the optical fiber during use, resulting in a better etching effect on the optical fiber during use.

[0035] Subsequently, the user places the natural rubber plugs 21 on the surface of the clamp body 1 and pushes the natural rubber plugs 21, causing the natural rubber plugs 21 to drive the rubber plugs 24 into the groove 112. At this time, the rubber plugs 24 drive the rubber protrusions 23 to move until they contact the inner wall of the groove 112. The natural rubber plugs 21 drive the clips 22 to automatically snap onto the surface of the clamp body 1, thereby installing the natural rubber plugs 21 on the surface of the clamp body 1. Under the combined action of the natural rubber plugs 21 and 24, a sealing treatment is performed between the optical fiber body 104 and the groove 112 to achieve the high sealing function of the clamp. This allows the clamp body 1 and the sealing cover 103 to be sealed during use, avoiding the leakage of hydrofluoric acid solution during the use of the clamp, and finally completing the use of the clamp.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
