Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a universal optical waveguide bidirectional coupling clamp. Background Technology

[0002] Optical waveguide coupling involves aligning the optical waveguide with other optical transmission elements to form an optical transmission path. An optical waveguide typically has two ports: an optical input and an optical output. Traditional optical waveguide coupling is unidirectional, with two separate unidirectional couplings completing the coupling at the optical input and output ends to achieve final optical coupling.

[0003] Existing general-purpose optical waveguide bidirectional coupling test fixtures mostly clamp the general-purpose optical waveguide bidirectional coupler by rotating a screw located on one side, causing the screw to move one compression plate closer to another fixed compression plate. This process requires frequent rotation of the screw, which is cumbersome and not fast enough for positioning. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal optical waveguide bidirectional coupling fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A universal optical waveguide bidirectional coupling fixture includes a base, a mounting workpiece fixed to one side of the top of the base, a fixing sleeve fixed to the mounting workpiece, and a mounting tube passing through the fixing sleeve. A pressing pusher for pushing the mounting tube is mounted on the mounting workpiece. A threaded rod is threadedly connected to the mounting tube. A rotating sleeve is fixed to the outer end face of the threaded rod, and a pressing plate is rotatably connected to the rotating sleeve. A second protective pad is adhered to the outer wall of the pressing plate. A fixing plate is fixed to the top of the base at a position corresponding to the pressing plate, and a first protective pad is adhered to the inside of the fixing plate.

[0007] As a further embodiment of this utility model, the outer wall of the rotating sleeve is coaxially fixed with an opening mounting block, the extrusion plate is provided with a mounting hole corresponding to the opening mounting block, and the opening mounting block is provided with a screw hole. The extrusion plate and the opening mounting block are fixed by a locking screw.

[0008] As a further embodiment of this utility model, the extrusion pusher includes a pressing handle rotatably connected to the top of the workpiece, an arc-shaped connecting plate rotatably connected to the bottom of the pressing handle, and the other end of the arc-shaped connecting plate rotatably connected to the mounting sleeve.

[0009] As a further embodiment of this utility model, a limiting guide block is fixed at the bottom of the extrusion plate, and a guide groove for the limiting guide block to slide is provided at the top of the base.

[0010] As a further embodiment of this utility model, a mounting platform is installed at the bottom of the base, and the base is rotatably connected to the mounting platform. A mounting screw head is fixed at the top of the mounting platform, and a hole is opened at the top of the base for the mounting screw head to pass through. A locking nut is threadedly connected to the portion of the mounting screw head that passes through the hole. A mounting platform is provided at the bottom of the base, and the mounting platform and the base are installed together by the mounting screw head and the locking nut. Twisting the locking nut causes it to press against the base, which can ensure that the base will not rotate. Twisting the locking nut in the opposite direction prevents it from pressing against the base, which facilitates the adjustment of the base angle.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention addresses the problems raised in the prior art by incorporating a base, an extrusion pusher, an extrusion plate, and a fixing plate. Furthermore, when the threaded rod rotates, the limiting guide block at the bottom of the extrusion plate slides within the guide groove, allowing for adjustment of the distance between the extrusion plate and the fixing plate. This effectively solves the problems mentioned in the prior art. Based on the dimensions of the universal optical waveguide bidirectional coupler, after positioning the press lever by its maximum counter-clockwise deflection angle, the extrusion plate is adjusted so that the extrusion plate and the fixing plate precisely clamp the universal optical waveguide bidirectional coupler. Subsequently, each universal optical waveguide bidirectional coupler of this size can be quickly positioned by pressing the press lever. The position of the extrusion plate can be adjusted according to different sizes to achieve rapid subsequent positioning.

[0013] This utility model features a mounting platform located at the bottom of the base. The mounting platform is installed on the base using mounting screws and locking nuts. Twisting the locking nut causes it to press against the base, preventing the base from rotating. Twisting the locking nut in the opposite direction prevents it from pressing against the base, facilitating the adjustment of the base's angle. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Reference Figure 1-4 A general-purpose optical waveguide bidirectional coupling fixture includes a base 1, a mounting workpiece 9 fixed on one side of the top of the base 1, a fixing sleeve 12 fixed on the mounting workpiece 9, and a mounting sleeve 13 passing through the fixing sleeve 12. A pressing pusher 2 for pushing the mounting sleeve 13 is mounted on the mounting workpiece 9. A threaded rod 14 is threadedly connected inside the mounting sleeve 13. A rotating sleeve 15 is fixed on the outer end face of the threaded rod 14, and a pressing plate 3 is rotatably connected to the rotating sleeve 15. A second protective pad 6 is adhered to the outer wall of the pressing plate 3. A fixing plate 4 is fixed on the top of the base 1 at the position corresponding to the pressing plate 3, and a first protective pad 5 is adhered to the inside of the fixing plate 4.

[0022] In this embodiment, the outer wall of the rotating sleeve 15 is coaxially fixed with a hole mounting block 16, the extrusion plate 3 is provided with a mounting hole 17 corresponding to the hole mounting block 16, and the hole mounting block 16 is provided with a screw hole. The extrusion plate 3 and the hole mounting block 16 are fixed by a locking screw head 18.

[0023] In this embodiment, the extrusion pusher 2 includes a pressing handle 10 rotatably connected to the top of the mounting workpiece 9, and an arc-shaped connecting plate 11 rotatably connected to the bottom of the pressing handle 10. The other end of the arc-shaped connecting plate 11 is rotatably connected to the mounting sleeve 13.

[0024] In this embodiment, a limiting guide block 7 is fixed at the bottom of the extrusion plate 3, and a guide groove 8 is provided at the top of the base 1 for the limiting guide block 7 to slide.

[0025] In this embodiment, a mounting platform 19 is installed at the bottom of the base 1. The base 1 and the mounting platform 19 are rotatably connected. A mounting screw head 20 is fixed at the top of the mounting platform 19. A hole for the mounting screw head 20 to pass through is opened at the top of the base 1. A locking nut 21 is threadedly connected to the part of the mounting screw head 20 that passes through the hole. The mounting platform 19 is located at the bottom of the base 1, and the mounting platform 19 and the base 1 are installed through the mounting screw head 20 and the locking nut 21. Twisting the locking nut 21 to press the base 1 can ensure that the base 1 will not rotate. Twisting the locking nut 21 in the opposite direction can prevent it from pressing the base 1, which facilitates the adjustment of the angle of the base 1.

[0026] Working principle: The system comprises a base 1, an extrusion pusher 2, an extrusion plate 3, and a fixing plate 4. During use, the universal optical waveguide bidirectional coupler is placed on the base 1 between the extrusion plate 3 and the fixing plate 4. The pressing handle 10 is held and rotated counterclockwise. Under the action of the arc-shaped connecting plate 11, the mounting sleeve 13 is pushed to move within the fixing sleeve 12. The threaded rod 14 on the mounting sleeve 13 moves the extrusion plate 3 closer to the fixing plate 4, ultimately clamping and fixing the universal optical waveguide bidirectional coupler located between the extrusion plate 3 and the fixing plate 4. In this design, the threaded rod 14 is threadedly connected to the mounting sleeve 13, and the extrusion plate 3 is fixed to the perforated mounting block 16 via a locking screw head 18 passing through the mounting hole 17. The extrusion plate 3 is fixed to ensure that it can rotate relative to the opening mounting block 16. When the threaded rod 14 rotates, the limiting guide block 7 at the bottom of the extrusion plate 3 slides in the guide groove 8. The distance between the extrusion plate 3 and the fixing plate 4 can be adjusted by means of adjustment, which effectively solves the problem mentioned in the background technology. According to the size of the universal optical waveguide bidirectional coupler, after the pressing handle 10 is positioned by deflecting counterclockwise to the maximum angle, the extrusion plate 3 is adjusted so that the extrusion plate 3 and the fixing plate 4 can clamp the universal optical waveguide bidirectional coupler. In the future, each universal optical waveguide bidirectional coupler of this size can be quickly positioned by pressing the pressing handle 10. The position of the extrusion plate 3 can be adjusted according to different sizes to achieve subsequent rapid positioning.
