[0001] This utility model relates to the field of packaging structure technology, specifically to a packaging structure for an optical power adjustable multiplexer. Background Technology
[0002] An optical power adjustable multiplexer is a passive optical device that can adjust optical power and combine multiple optical signals within a certain range. It is mainly used in optical fiber communication systems to meet different communication needs by adjusting optical power and combining multiple optical signals. In optical fiber communication systems, adjusting optical power and combining multiple optical signals optimizes signal transmission quality. In the testing and maintenance of optical fiber lines, it is used to adjust optical power and combine signals to facilitate fault diagnosis and performance optimization.
[0003] When in use, the structure of an optical power adjustable multiplexer is sealed by an external housing. The housing structure is mostly fixed by several bolts, which means that when maintaining the internal structure, it is necessary to tighten multiple bolts one by one. Moreover, because the bolts are small in size, they are easy to lose after being tightened and removed, which increases the difficulty of opening the encapsulation structure. Based on this, this utility model designs an encapsulation structure for an optical power adjustable multiplexer to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a packaging structure for an optical power adjustable multiplexer, so as to solve the problem mentioned in the background art that the packaging structure of the existing optical power adjustable multiplexer is difficult and cumbersome to open.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging structure for an optical power adjustable multiplexer, comprising a lower sealing shell and an upper sealing shell, wherein the upper sealing shell covers the top surface of the lower sealing shell, and a plurality of fixing rods are equidistantly fixed on both sides of the bottom surface inside the upper sealing shell, and a fixing block is slidably disposed inside the lower sealing shell on one side of each fixing rod, the bottom of each fixing block being fixed to the top surface of a connecting sleeve rod, and an adjusting screw threadedly connected inside the two connecting sleeve rods, both ends of each adjusting screw being rotatably connected to the inner wall of the lower sealing shell via bearings, and one end of each adjusting screw extending rotatably to the outside of the lower sealing shell, with limiting frames symmetrically slidably fitted on the outside of the two connecting sleeve rods, and the side of each limiting frame being fixed to the inner side wall of the lower sealing shell.
[0006] Preferably, a fixing pad is fixed to the middle of both sides of the lower sealing shell, and a fixing hole is opened inside the fixing pad. Each connecting sleeve rod is opened with a threaded hole that cooperates with the adjusting screw.
[0007] Preferably, a sealing plate is fixed to the bottom of the upper sealing shell, a sealing groove that mates with the sealing plate is opened on the top surface of the lower sealing shell, and a sealing gasket is glued to the bottom surface of the sealing plate.
[0008] Preferably, each of the fixing rods is configured as a J-shape, and the opposite sides of each fixing rod and fixing block are configured as relatively close inclined shapes.
[0009] Preferably, a guide block is fixed on the inner wall of the lower sealing shell on the side of each fixed clamping rod away from the fixed clamping block, and an auxiliary push block is fixed on the top surface of the connecting sleeve rod below the guide block. Each auxiliary push block is set to the same inclined shape as the bottom of the fixed clamping rod.
[0010] Preferably, each of the limiting sleeves is configured as a transversely placed U-shape that cooperates with the connecting sleeve rod, and both connecting sleeve rods have threaded holes inside that cooperate with the adjusting screw.
[0011] Preferably, a knob is fixed to one end of the adjusting screw extending to the outside of the lower sealing shell, and a protective cover is fixed to the outer surface of the lower sealing shell outside the knob. The protective cover is configured as a U-shape to cooperate with the knob.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) This utility model uses a flat push and squeeze design on both sides. When sealing, the fixing rod at the bottom of the upper sealing shell is inserted into the lower sealing shell, and then fixed by the fixing block. The upper and lower sealing shells can be fixed. The operation of fixing and disassembling is simple and convenient. It solves the problem that the existing optical power adjustable multiplexer packaging structure is difficult and cumbersome to open, and avoids the problem of losing parts after disassembly.
[0014] (2) Through the sealing structure of the contact surface of the upper and lower sealing shells, the sealing performance of the upper and lower sealing shells can be ensured by the cooperation of the sealing plate and the sealing gasket during use. The auxiliary push block on the side can quickly and effortlessly push the upper sealing shell out of the lower sealing shell when opening the sealing structure. Attached Figure Description

Detailed Implementation
[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution: a packaging structure for an optical power adjustable multiplexer, including a lower sealing shell 1 and an upper sealing shell 2. A fixing pad 3 is fixed to the middle of both sides of the lower sealing shell 1. Each fixing pad 3 has a fixing hole inside. Each connecting sleeve rod 6 has a threaded hole inside that mates with an adjusting screw 8. The upper sealing shell 2 covers the top surface of the lower sealing shell 1. Several fixing rods 4 are equidistantly fixed to both sides of the bottom surface inside the upper sealing shell 2. A fixing block 5 is slidably disposed inside the lower sealing shell 1 on one side of each fixing rod 4. Each fixing rod 4 is J-shaped. The opposite sides of each fixing rod 4 and fixing block 5 are inclined and relatively close. The bottom of each fixing block 5 is fixed to the top surface of the connecting sleeve rod 6. Both connecting sleeve rods 6 are threaded with adjusting screws 8. Both ends of each adjusting screw 8 are rotatably connected to the inner wall of the lower sealing shell 1 through bearings. One end of each adjusting screw 8 extends rotatably to the outside of the lower sealing shell 1. A knob 9 is fixed to the end of the adjusting screw 8 extending to the outside of the lower sealing shell 1. A protective cover 10 is fixed to the outer surface of the lower sealing shell 1 outside the knob 9. The protective cover 10 is U-shaped and cooperates with the knob 9. Limiting sleeve frames 7 are symmetrically slidably fitted on the outside of both connecting sleeve rods 6. Each limiting sleeve frame 7 is a transversely placed U-shaped and cooperates with the connecting sleeve rod 6. Both connecting sleeve rods 6 have threaded holes that cooperate with the adjusting screws 8. The side of each limiting sleeve frame 7 is fixed to the inner wall of the lower sealing shell 1.
[0024] When it is necessary to encapsulate the internal components of the lower sealing shell 1, after the optical power adjustable multiplexer is assembled, the upper sealing shell 2 is placed on the top surface of the lower sealing shell 1, so that the fixing rod 4 is inserted into the lower sealing shell 1 under the guidance of the guide block 11. Then, the knob 9 is rotated, so that the knob 9 drives the adjusting screw 8 to rotate. When the adjusting screw 8 rotates, it drives the connecting sleeve 6 inside to slide inside the limiting sleeve 7. When the connecting sleeve 6 slides, it drives the fixing block 5 to move to press against the top surface of the fixing rod 4. During the movement of the fixing block 5, it pushes the fixing rod 4 down, so that the upper sealing shell 2 is pressed and fixed on the top surface of the lower sealing shell 1, thus fixing and sealing the lower sealing shell 1 and the upper sealing shell 2. When disassembling, the knob 9 is rotated in the opposite direction, so that the fixing block 5 moves to release the limit on the fixing rod 4, thus separating the upper sealing shell 2 from the lower sealing shell 1 and opening the lower sealing shell 1.
[0025] Please see Figure 1-4 The bottom of the upper sealing shell 2 is fixed with a sealing plate 14, and the top surface of the lower sealing shell 1 is provided with a sealing groove 13 that cooperates with the sealing plate 14. A sealing gasket 15 is glued to the bottom surface of the sealing plate 14. A guide block 11 is fixed on the inner wall of the lower sealing shell 1 on the side of each fixing rod 4 away from the fixing block 5. An auxiliary push block 12 is fixed on the top surface of the connecting sleeve rod 6 below the guide block 11. Each auxiliary push block 12 is set to the same inclined shape as the bottom of the fixing rod 4.
[0026] During the encapsulation process, when the upper sealing shell 2 covers the top surface of the lower sealing shell 1, it causes the sealing plate 14 to be inserted into the sealing groove 13. As the fixing block 5 pushes the fixing rod 4 downward, it causes the sealing plate 14 to move downward and squeeze the sealing gasket 15. The sealing gasket 15 ensures the sealing at the connection between the lower sealing shell 1 and the upper sealing shell 2. When the lower sealing shell 1 is opened and the knob 9 is rotated in the opposite direction, the connecting sleeve rod 6 moves toward the fixing block 5. During the movement, it causes the auxiliary push block 12 to move toward the fixing rod 4. After the auxiliary push block 12 moves below the fixing rod 4, it pushes the fixing rod 4 upward, causing the upper sealing shell 2 to move upward and creating a gap between it and the lower sealing shell 1, making it easier to remove the upper sealing shell 2.
