Description

Technical Field

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

[0002] The positioning device for fiber optic testing is a specialized equipment system used in fiber optic testing to achieve precise positioning, attitude adjustment, or spatial coordinate locking of the fiber. Its core function is to ensure that the fiber is in a preset stable position or precisely aligned with the testing instrument during the testing process through mechanical structures, sensing technology, or optical assistance, thereby guaranteeing testing accuracy, efficiency, and reliability.

[0003] Existing patent document CN220472934U discloses a positioning device for optical fiber testing, including an XY moving platform, an experimental platform, an optical fiber rotating clamp, a platform glass plate, and an optical fiber clamping mechanism. The XY moving platform is installed at the bottom of the experimental platform, and the optical fiber rotating clamp, platform glass plate, and optical fiber clamping mechanism are all fixed on the experimental platform, with the optical fiber rotating clamp and optical fiber clamping mechanism located on both sides of the platform glass plate. This invention can fix the optical fiber sample to be observed, thus preventing the cylindrical optical fiber from deviating; it also allows for convenient adjustment of the optical fiber position during multiple observations, saving time and effort; furthermore, it can rotate the optical fiber towards a fixed X or Y plane or a fixed angular direction, thereby more accurately positioning the optical fiber to be tested or observed.

[0004] However, existing fiber optic testing positioning devices, while capable of rotating the fiber in a fixed X or Y plane or at a fixed angle, are cumbersome to operate, requiring the operation of multiple fixing components to position and fix the fiber, thus affecting the fixing efficiency. Furthermore, it is difficult to limit the fixing force during the positioning and fixing process, which can easily lead to damage to the fiber. Therefore, we propose a fiber optic testing positioning device. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the present invention provides a positioning device for optical fiber detection to solve the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for fiber optic detection, comprising a mounting base, a rotating seat integrally formed at the bottom of the mounting base, an installation groove at the center of the bottom of the rotating seat, a reset ring installed inside the installation groove, a connecting sleeve installed at one end of the reset ring, a positioning groove at the center of the top of the mounting base, fixed brackets bolted to both sides of the top of the mounting base, a telescopic rod installed at the top of the fixed brackets, a buffer sleeve slidably connected to the bottom end of the telescopic rod, a buffer groove inside the buffer sleeve, a buffer spring installed inside the buffer groove, and a positioning plate bolted to the bottom of the buffer sleeve.

[0009] Preferably, the outer side of the connecting sleeve is integrally formed with an external toothed ring, and multiple external toothed rings are provided, with the multiple external toothed rings being of the same size.

[0010] Preferably, the inner wall of the mounting groove is integrally formed with an internal toothed ring, which meshes with an external toothed ring.

[0011] Preferably, the positioning groove is V-shaped and the outer surface of the positioning groove is smooth.

[0012] Preferably, the bottom of the connecting sleeve is integrally formed with a mounting plate, which is made of metal material.

[0013] Preferably, the bottom end of the telescopic rod is located inside the buffer groove, and the telescopic rod is movably connected to the buffer groove.

[0014] (III) Beneficial Effects

[0015] This utility model provides a positioning device for fiber optic detection, which has the following beneficial effects:

[0016] (1) The positioning device for optical fiber detection, through the installation base, positioning groove and positioning plate, when using the positioning device for optical fiber detection, the staff places the optical fiber in the positioning groove of the installation base, and then starts the telescopic rod. The telescopic rod drives the positioning plate to move downward. At this time, the positioning plate can press the optical fiber to play a fixing role. Since the positioning groove is V-shaped, when the optical fiber is in the positioning groove, it will be directly centered in the center of the positioning groove. As the positioning plate moves downward, the positioning plate can fix the optical fiber in the center. This positioning device simplifies the operation steps and improves the positioning and fixing efficiency.

[0017] (2) The positioning device for this type of optical fiber detection, through the buffer sleeve, buffer groove and buffer spring, when the optical fiber is fixed in the center of the positioning plate, the thrust generated by the telescopic rod needs to be applied to the positioning plate through the buffer spring in the buffer sleeve. When the thrust generated causes the positioning plate to press the optical fiber to reach the force that the buffer spring can bear, the telescopic rod will squeeze the buffer spring and enter the buffer groove, thereby playing a buffering role, avoiding excessive force in fixing the optical fiber, and thus preventing damage to the optical fiber during the fixing process.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a positioning device for fiber optic detection, including a mounting base 2, a rotating base 1 integrally formed at the bottom of the mounting base 2, a mounting groove 12 opened at the center of the bottom of the rotating base 1, a reset ring 11 installed on the inner side of the mounting groove 12, a connecting sleeve 9 installed at one end of the reset ring 11, a positioning groove 3 opened at the center of the top of the mounting base 2, a fixing bracket 4 bolted to both sides of the top of the mounting base 2, a telescopic rod 5 installed on the top of the fixing bracket 4, a buffer sleeve 6 slidably connected to the bottom end of the telescopic rod 5, a buffer groove 601 opened inside the buffer sleeve 6, a buffer spring 602 installed inside the buffer groove 601, and a positioning plate 7 bolted to the bottom of the buffer sleeve 6.

[0025] Furthermore, the outer side of the connecting sleeve 9 is integrally formed with an external toothed ring 10. Multiple external toothed rings 10 are provided, and the multiple external toothed rings 10 are the same size. The external toothed rings 10 can be used to engage with the internal toothed ring 13.

[0026] Furthermore, the inner wall of the mounting groove 12 is integrally formed with an inner toothed ring 13, which meshes with the outer toothed ring 10, so that the inner toothed ring 13 and the outer toothed ring 10 can be engaged with each other.

[0027] Furthermore, the positioning groove 3 is V-shaped and its outer surface is smooth. Since the positioning groove 3 is V-shaped, when the optical fiber is located inside the positioning groove 3, it will be directly centered in the center of the positioning groove 3.

[0028] Furthermore, the bottom of the connecting sleeve 9 is integrally formed with an installation plate 8, which is made of metal material. The installation plate 8 facilitates the installation of the positioning device by the staff.

[0029] Furthermore, the bottom end of the telescopic rod 5 is located inside the buffer groove 601. The telescopic rod 5 is movably connected to the buffer groove 601. When the thrust of the telescopic rod 5 causes the positioning plate 7 to press the optical fiber to the force that the buffer spring 602 can withstand, the telescopic rod 5 will squeeze the buffer spring 602, and the telescopic rod 5 will enter the buffer groove 601, thereby playing a buffering role.

[0030] Working Principle: After installation, first check the installation, fixation, and safety protection of this utility model. When using the fiber optic detection positioning device, the operator places the fiber optic cable in the positioning groove 3 of the mounting base 2, and then activates the telescopic rod 5. The telescopic rod 5 moves the positioning plate 7 downwards. At this time, the positioning plate 7 can press down on the fiber optic cable to fix it. Since the positioning groove 3 is V-shaped, when the fiber optic cable is located in the positioning groove 3, it will be directly centered in the center of the positioning groove 3. As the positioning plate 7 moves downwards, it can fix the fiber optic cable in the center. This completes the use of this utility model. When the positioning plate 7 fixes the fiber optic cable in the center, the telescopic rod 5 moves downwards to fix the fiber optic cable in the center. The thrust generated by rod 5 needs to be applied to the positioning plate 7 through the buffer spring 602 in the buffer sleeve 6. When the thrust causes the positioning plate 7 to press the optical fiber to the force that the buffer spring 602 can withstand, the telescopic rod 5 will squeeze the buffer spring 602 and enter the buffer groove 601, thereby playing a buffering role. During the positioning process, the operator can pull the rotating seat 1 upward, and the internal toothed ring 13 in the mounting groove 12 at the bottom of the rotating seat 1 can stretch the reset ring 11, so that the internal toothed ring 13 disengages from the external toothed ring 10 on the connecting sleeve 9. At this time, the operator can rotate and adjust the rotating seat 1. This utility model has a simple structure and is safe and convenient to use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
