Description

Technical Field

[0001] This utility model relates to the field of coarse wavelength division multiplexer technology, specifically a two-in-one multi-channel compact coarse wavelength division multiplexer. Background Technology

[0002] With the rapid development of information technology, the demand for data transmission in various fields has exploded. In many scenarios such as communications, data centers, and industrial production, large amounts of data need to be transmitted and exchanged quickly and stably.

[0003] Current technology uses bolts to secure wavelength division multiplexers (WDMs). In scenarios requiring frequent adjustments or replacements of WDMs, the removal and reinstallation of these bolts is extremely cumbersome. For example, in the expansion and renovation of outdoor mobile communication base stations, when adding WDMs to existing base station equipment to extend signal transmission channels, workers must use specialized tools to unscrew each bolt individually. After installing the WDM, they must carefully tighten the bolts to ensure a secure fit. This entire process is time-consuming and labor-intensive, significantly impacting project progress. Utility Model Content

[0004] The purpose of this invention is to provide a two-in-one compact coarse wavelength division multiplexer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a two-in-one multi-channel compact coarse wavelength division multiplexer, comprising a wavelength division multiplexer body, and further comprising:

[0006] A transmission assembly is placed inside the wavelength division multiplexer body. The transmission assembly includes a first fixed rod fixedly connected to the wavelength division multiplexer body, a lower pressure plate slidably connected to the transmission assembly, a first fixed frame fixedly connected to the lower pressure plate, a first sliding shaft slidably connected to the first fixed frame, a second fixed rod fixedly connected to the first sliding shaft, and a connecting rod fixedly connected to the second fixed rod.

[0007] A sealing assembly includes a first transmission rod fixedly connected to a lower pressure plate, a second transmission rod fixedly connected to the first transmission rod, a third transmission rod slidably connected to the second transmission rod, a sliding block slidably connected to the third transmission rod, a second sliding shaft fixedly connected to the sliding block, and a baffle plate fixedly connected to the second sliding shaft.

[0008] Furthermore, the connecting rod is slidably connected to the wavelength division multiplexer body, a first limiting block is fixedly connected to the second fixed rod, a connecting shaft is fixedly connected between the lower pressure plate and the first transmission rod, and a transmission block is fixedly connected between the second transmission rod and the third transmission rod.

[0009] The above technical solution is adopted: by setting a second limit block, the transmission block is limited during use.

[0010] Furthermore, the sliding block has an opening, and a conical block is fixedly connected to the third transmission rod. The opening on the sliding block is a conical opening.

[0011] The above technical solution is adopted: by opening a hole in the sliding block, when the conical block on the third transmission rod slides in the conical opening on the sliding block, the sliding block can be pushed to both sides.

[0012] Furthermore, the transmission block has an opening, and the second transmission rod is slidably connected to the opening on the transmission block.

[0013] The above technical solution is adopted: by opening a hole in the transmission block, when the second transmission rod slides in the opening in the transmission block during use, it will drive the transmission block to slide at the bottom of the wavelength division multiplexer body.

[0014] Furthermore, a connecting frame is slidably connected to the first limiting block, and an opening is provided on the side of the connecting frame near the first limiting block.

[0015] The above technical solution is adopted: by setting a connecting frame, the connecting frame is first fixed to the machine with bolts when in use. When it is necessary to disassemble or install the wavelength division multiplexer body, it is only necessary to slide the first limiting block out of the connecting frame or lock it.

[0016] Furthermore, a square plate is fixedly connected to the first fixed rod, and a second fixed frame is fixedly connected to the square plate on the first fixed rod. The first sliding shaft is slidably connected to the second fixed frame.

[0017] The above technical solution is adopted: by fixing a square plate to the first fixing rod, it is convenient to fix the second fixing frame during use.

[0018] Furthermore, the connecting rod is rotatably connected to the top of the wavelength division multiplexer body.

[0019] The above technical solution is adopted: by setting a connecting rod to be rotatably connected to the top of the wavelength division multiplexer body, when the second fixed rod rotates during use, the connecting rod will rotate synchronously.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, when an external force is applied to the lower pressure plate, the lower pressure plate will slide along the first fixed rod. This sliding will cause the first fixed frame connected to it to move synchronously, thereby causing the first sliding shaft to slide inside the first fixed frame. Finally, it will link the second fixed rod, connecting rod and other components to complete the cooperation action between the first limiting block and the connecting frame, realizing convenient installation and disassembly. Only the connecting frame needs to be fixed to the machine with bolts. When installing or disassembling the wavelength division multiplexer body, it is only necessary to operate the first limiting block to slide out or snap into the connecting frame. The operation is extremely simple and solves the problem of frequent screw unscrewing required for installation and disassembly in the prior art.

[0022] In this invention, the lower pressure plate presses down, causing the connecting shaft to move accordingly. The connecting shaft then drives the first transmission rod, which in turn drives the second transmission rod to slide within the opening of the transmission block. This causes the transmission block to slide at the bottom of the wavelength division multiplexer body. The transmission block then drives the third transmission rod, at which point the conical block on the third transmission rod slides within the conical opening of the sliding block, pushing the sliding block to both sides. Ultimately, this causes the second sliding shaft to move the shielding plate, successfully exposing the lens of the wavelength division multiplexer body. This meets the requirements for normal equipment use and prevents dust from falling into the lens when the wavelength division multiplexer is exposed during transportation.

[0032] 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.

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a two-in-one multi-channel compact coarse wavelength division multiplexer, including a wavelength division multiplexer body 1, and further including:

[0034] Transmission assembly 2 is placed inside wavelength division multiplexer body 1. Transmission assembly 2 includes a first fixed rod 21 fixedly connected to wavelength division multiplexer body 1, a lower pressure plate 29 slidably connected to transmission assembly 2, a first fixed frame 25 fixedly connected to lower pressure plate 29, a first sliding shaft 24 slidably connected to first fixed frame 25, a second fixed rod 23 fixedly connected to first sliding shaft 24, and a connecting rod 22 fixedly connected to second fixed rod 23.

[0035] The sealing component 3 includes a first transmission rod 32 fixedly connected to the lower pressure plate 29, a second transmission rod 33 fixedly connected to the first transmission rod 32, a third transmission rod 37 slidably connected to the second transmission rod 33, a sliding block 35 slidably connected to the third transmission rod 37, a second sliding shaft 38 fixedly connected to the sliding block 35, and a baffle plate 36 fixedly connected to the second sliding shaft 38.

[0036] In this invention, when an external force is applied to the lower pressure plate 29, the lower pressure plate 29 will slide along the first fixed rod 21. This sliding causes the first fixed frame 25 connected to it to move synchronously, thereby causing the first sliding shaft 24 to slide inside the first fixed frame 25. Finally, it links the second fixed rod 23, connecting rod 22, and other components to complete the cooperation action between the first limiting block 26 and the connecting frame 27, achieving convenient installation and disassembly. Only the connecting frame 27 needs to be fixed to the machine with bolts. When installing or disassembling the wavelength division multiplexer body 1, it is only necessary to operate the first limiting block 26 to slide out or snap into the connecting frame 27. The operation is extremely simple, solving the problem of frequent screw unscrewing required for installation and disassembly in the prior art.

[0037] The connecting rod 22 is slidably connected to the wavelength division multiplexer body 1. A first limiting block 26 is fixedly connected to the second fixed rod 23. A connecting shaft 31 is fixedly connected between the lower pressure plate 29 and the first transmission rod 32. A transmission block 34 is fixedly connected between the second transmission rod 33 and the third transmission rod 37. In the actual operation of the wavelength division multiplexer, each component is in a continuous state of motion. The movement trajectory and range of the transmission block 34 directly affect the working effect of the entire enclosed assembly 3. If the movement of the transmission block 34 exceeds the predetermined range, it may cause collisions or interference with other components, thereby affecting the normal operation of the equipment and even causing damage to the components. The sliding connection of the second limiting block 39 in the slot at the bottom of the wavelength division multiplexer body 1 is like setting a precise track for the transmission block 34, ensuring that the transmission block 34 can only slide within the specified range, avoiding excessive displacement, making the entire transmission process more stable and reliable, and effectively improving the operational stability and service life of the equipment.

[0038] The sliding block 35 has an opening, and a conical block is fixedly connected to the third transmission rod 37. The opening on the sliding block 35 is conical. When the wavelength division multiplexer is working, the third transmission rod 37 moves accordingly, and the conical block slides within the conical opening of the sliding block 35. Due to the special shape of the cone, as the conical block moves deeper or further out of the opening, a lateral force is generated. This force precisely pushes the sliding block 35 to both sides. This converts the linear motion of the third transmission rod 37 into the lateral motion of the sliding block 35, achieving the conversion between different directions of motion. This provides crucial power transmission for the operation of the enclosure component 3, allowing the shielding plate 36 to move according to design requirements, thereby achieving the shielding or exposure of specific parts of the wavelength division multiplexer and meeting the needs of the equipment under different operating conditions.

[0039] An opening is provided on the transmission block 34, and the second transmission rod 33 is slidably connected within the opening on the transmission block 34, ensuring the directness and efficiency of power transmission and making the transmission process more flexible. By rationally designing the size and shape of the opening, the movement speed and displacement of the transmission block 34 can be controlled, thereby achieving precise control of other components of the enclosed assembly 3, ensuring that the entire equipment operates according to a predetermined program and rhythm, and improving the working accuracy and reliability of the equipment.

[0040] A connecting frame 27 is slidably connected to the first limiting block 26. An opening is provided on the side of the connecting frame 27 near the first limiting block 26. In practical applications, such as during the construction, maintenance, or upgrade of communication base stations, it is frequently necessary to install, disassemble, or replace wavelength division multiplexers. Traditional bolt fixing methods are not only time-consuming and labor-intensive when performing these operations frequently, but may also affect the stability of the equipment due to loosening or damage to the bolts. However, with the design of the connecting frame 27, the connecting frame 27 is first fixed to the machine using bolts. When installing or disassembling the wavelength division multiplexer body 1, it is only necessary to slide the first limiting block 26 off or lock it onto the connecting frame 27.

[0041] A square plate is fixedly connected to the first fixed rod 21, and a second fixed frame 28 is fixedly connected to the square plate on the first fixed rod 21. The first sliding shaft 24 is slidably connected to the second fixed frame 28. The square plate is fixedly connected to the first fixed rod 21, and the second fixed frame 28 is fixed on the square plate. This provides strong support for the structural stability of the entire transmission assembly 2 and the installation of components, reduces problems such as motion jamming or excessive friction caused by inaccurate installation, ensures the efficient operation of the transmission assembly 2, and improves the overall performance of the equipment.

[0042] The connecting rod 22 is rotatably connected to the top of the wavelength division multiplexer body 1. When the second fixed rod 23 rotates, since the connecting rod 22 is fixedly connected to the second fixed rod 23 and rotatably connected to the top of the wavelength division multiplexer body 1, the connecting rod 22 will rotate synchronously, so that the movement of the second fixed rod 23 can be transmitted to other related components, realizing the effective transmission of power and the coordinated work of components, ensuring that the shielding plate 36 can move in a predetermined manner.

[0043] like Figures 1-5 As shown, during use, the connecting frame 27 is first fixed to the machine with bolts, and the first limiting block 26 is placed on the opening at the bottom of the connecting frame 27. At this time, the lower pressure plate 29 is pressed by external force, which causes the lower pressure plate 29 to drive the internal gear first fixing frame 25 to press down. This causes the first sliding shaft 24 to rotate under the limiting action of the slot at the bottom of the first fixing frame 25, and causes the first limiting block 26 to rotate inside the connecting frame 27 and get stuck inside the connecting frame 27, thus completing the installation of the wavelength division multiplexer body 1.

[0044] During this process, when the second rotating shaft pressure plate 29 is pressed down, it will drive the connecting shaft 31 to press down, causing the first transmission rod 32 to be driven down. This causes the first transmission rod 32 to drive the second transmission rod 33 to slide on the transmission block 34, causing the first sliding shaft 24 to slide towards the side closer to the sliding block 35. This causes the third transmission rod 37 to push the sliding block 35 to both sides, causing the shielding plate 36 to move to both sides, exposing the lens of the wavelength division multiplexer body 1. When not in use, the lens is protected and dustproof.

[0045] 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 way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
