Description

Technical Field

[0001] This utility model relates to the field of dense wavelength division multiplexer (DWDM) technology, and in particular to a support for a dense wavelength division multiplexer. Background Technology

[0002] Dense wavelength division multiplexers significantly improve the transmission capacity and efficiency of optical fibers by transmitting multiple wavelengths of optical signals in a single optical fiber.

[0003] However, in order to ensure the stable operation of dense wavelength division multiplexers, their installation and commissioning require a high-precision support structure to adapt to the installation requirements of different equipment and provide flexible adjustment functions.

[0004] However, some existing bracket adjustment methods usually require disassembly or reassembly of components, which cannot quickly adapt to the installation requirements of different equipment. Under frequent adjustments or equipment vibration, the structure of existing brackets is prone to loosening, causing the equipment position to shift and affecting the transmission efficiency of optical signals.

[0005] Therefore, this utility model provides a bracket for a dense wavelength division multiplexer. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a support for dense wavelength division multiplexers.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a bracket for a dense wavelength division multiplexer, including a mounting frame, wherein a spacing adjustment component is rotatably connected inside the mounting frame;

[0008] A support assembly includes a central column slidably connected to a mounting bracket. The central column has grooves at both ends on its outer side, and a slider is slidably connected to the groove. An arc-shaped spring is fixedly connected inside the slider, and a retaining plate is fixedly connected to the end of the arc-shaped spring away from the slider.

[0009] In a preferred embodiment, the spacing adjustment assembly includes an adjustment rod rotatably connected to the mounting bracket, with protruding rods fixedly connected to both outer ends of the adjustment rod.

[0010] In a preferred embodiment, the protruding rod is provided with a threaded groove, and a threaded post is threadedly connected to the threaded groove.

[0011] In a preferred embodiment, a limiting post is fixedly connected inside the mounting bracket, and an adjusting handle is fixedly connected to the outside of the adjusting rod.

[0012] In a preferred embodiment, the inner side of the central post is threadedly connected to the outer side of the threaded post, and the inner end of the central post away from the threaded post is slidably connected to the limiting post.

[0013] In a preferred embodiment, the threaded groove and the threaded post are designed with reverse threads, and the outer side of the clamping plate is slidably connected to the inside of the mounting bracket.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention uses an adjustable handle to rotate an adjusting rod, which in turn drives the reverse threaded grooves at both ends to move in tandem with the threaded columns, causing the center columns on both sides to slide horizontally along the limiting columns, thus adjusting the spacing synchronously. When the center columns move, the sliding grooves and sliders work together to pull the arc-shaped spring sheet to deform elastically, pushing the clamping plate to self-adaptively clamp the device. This design, through the coupling of threaded transmission and elastic deformation, allows for device clamping and spacing adjustment simply by rotating the adjusting handle, improving operational efficiency. Furthermore, the self-locking characteristics of the reverse threads and the continuous elastic pressure of the arc-shaped spring sheet ensure that the device remains stably clamped even under vibration, effectively solving the problem that existing technologies often cause the structure of the support to loosen under frequent adjustments or device vibration, leading to device position displacement.

[0025] 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.

[0026] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a bracket for a dense wavelength division multiplexer, including a mounting bracket 1;

[0027] Support component 2 includes a central column 21 slidably connected to the mounting frame 1. The central column 21 has grooves 22 at both ends on its outer side. A slider 23 is slidably connected to the grooves 22. An arc-shaped spring piece 24 is fixedly connected inside the slider 23. A retaining plate 25 is fixedly connected to the end of the arc-shaped spring piece 24 away from the slider 23. The outer side of the retaining plate 25 is slidably connected inside the mounting frame 1.

[0028] Mounting bracket 1 is the basic structure of the entire support system, used to fix and support other components, ensuring the stability and reliability of the entire device. The central column 21 is slidably connected to mounting bracket 1, used to support and fix the core components of the dense wavelength division multiplexer. Slide grooves 22 are formed at both ends of the outer side of the central column 21 for the sliding connection of slider 23, providing a sliding guide function to ensure smoother sliding of slider 23 on the central column 21, avoiding offset or jamming. Slide 23 is slidably connected to slide groove 22 for fixing arc-shaped spring 24. The sliding design of slider 23 allows for flexible adjustment of the positions of arc-shaped spring 24 and clamping plate 25 to adapt to the installation requirements of different equipment. Arc-shaped spring 24 is fixedly connected to... On the slider 23, clamping force is provided through elastic deformation to ensure close contact between the clamping plate 25 and the mounting bracket 1. The elastic design allows for a certain degree of deformation to adapt to different sizes of mounting brackets 1, enhancing versatility. The clamping plate 25 is fixedly connected to the other end of the arc-shaped spring 24, and its outer side is slidably connected to the inside of the mounting bracket 1 for limiting and fixing, ensuring that the bracket will not shift or loosen during adjustment, thus improving overall stability. In this way, when the clamping plate 25 contacts the dense wavelength division multiplexer, the arc-shaped spring 24 can achieve the purpose of pressurization, and the slider 23 can achieve fine adjustment at a certain distance by sliding on the slide groove 22, thereby achieving the purpose of stable support.

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a spacing adjustment assembly 3 is rotatably connected inside the mounting bracket 1. The spacing adjustment assembly 3 includes an adjustment rod 31 rotatably connected to the mounting bracket 1, and protruding rods 32 are fixedly connected to both ends of the outer side of the adjustment rod 31. A threaded groove 33 is provided on the protruding rod 32, and a threaded post 34 is threadedly connected to the threaded groove 33. The threaded groove 33 and the threaded post 34 are designed with opposite threads. One side of the inner side of the center post 21 is threadedly connected to the outer side of the threaded post 34. A limiting post 35 is fixedly connected inside the mounting bracket 1. The end of the center post 21 that is away from the threaded post 34 is slidably connected to the limiting post 35. An adjustment handle 36 is fixedly connected to the outer side of the adjustment rod 31.

[0030] The adjusting rod 31 is the core component of the spacing adjustment assembly 3. Rotating the adjusting rod 31 drives the movement of the threaded column 34, thereby changing the spacing of the center column 21. The protruding rod 32 is fixedly connected to both ends of the outer side of the adjusting rod 31 to provide the installation position of the threaded groove 33. The threaded groove 33 is formed on the protruding rod 32 for threaded connection with the threaded column 34. The design of the threaded groove 33 allows the threaded column 34 to move stably on the protruding rod 32, achieving precise spacing adjustment. The reverse thread design allows the threaded columns 34 on both sides to achieve positioning while moving and adjusting. The threaded column 34 is threadedly connected to the threaded groove 33 and threadedly connected to the inner side of the center column 21 to drive the movement of the center column 21. The limiting post 35 is fixedly connected inside the mounting bracket 1 to limit the movement range of the center column 21 and ensure that it does not deviate during adjustment. The adjusting handle 36 is fixedly connected to the outer side of the adjusting rod 31 for easy manual rotation by the user.

[0031] like Figure 1 - Figure 5 As shown:

[0032] In use: First, rotate the adjusting handle 36 to drive the adjusting rod 31, which is fixedly connected to it, to rotate synchronously. Then, the rotation of the adjusting rod 31 drives the protruding rods 32, which are fixedly connected at both ends, to rotate around the axis, so that the reverse threaded grooves 33 on the protruding rods 32 generate bidirectional displacement driving force. The rotation of the reverse threaded grooves 33 drives the threaded post 34, which is threadedly connected to it, to move in the opposite direction along the axial direction. Since one side of the central post 21 is threadedly connected to the threaded post 34, and the other side is slidably sleeved on the limiting post 35, the axial movement of the threaded post 34 can push the central posts 21 on both sides to slide horizontally along the guide trajectory of the limiting post 35, thus realizing... The distance between the two center columns 21 is synchronously expanded or reduced; when the distance between the center columns 21 is adjusted, the slide groove 22 fixed on the center column 21 moves accordingly, causing the slider 23 slidably connected in the slide groove 22 to move laterally; the movement of the slider 23 pulls the arc-shaped spring piece 24 fixed inside to produce elastic deformation, and pushes the clamping plate 25 fixed to the end of the spring piece to slide along the inner wall of the mounting frame 1; finally, under the action of the elastic restoring force of the arc-shaped spring piece 24, the clamping plate 25 tightly presses against the two outer shells of the dense wavelength division multiplexer, forming an adaptive clamping force, and at the same time, through the guiding constraint of the slide groove 22 and the slider 23, it ensures that the central axis of the equipment is precisely aligned with the fiber optic interface.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
