[0001] The present invention relates to the technical field of optical modems, and in particular to a communication optical modem that is easy to quickly install, disassemble and assemble. Background Art
[0002] With the rapid development of communications technology, optical modems, as key devices for fiber-to-the-home (FTTH) network access, are widely used in homes and businesses. Currently, common optical modems on the market typically use screws to connect the top cover to the bottom housing, and internal components also rely on screws and cables for fastening and connection. This traditional installation method has many drawbacks in actual use. On the one hand, the screw-tightening installation method makes the installation and disassembly process of the optical modem more cumbersome, requiring the use of tools such as screwdrivers to operate, which is not only time-consuming, but also seriously affects work efficiency in large-scale installation or emergency repair scenarios. On the other hand, frequent turning of screws can easily cause the screw holes to slip and be damaged, which in turn affects the stability of the overall structure of the optical modem and shortens the service life of the equipment; and during the disassembly process, if the operation is improper, it may also cause problems such as internal cables being pulled and broken, and components becoming loose, increasing maintenance costs and difficulty. In addition, the installation structure of traditional optical modems makes it difficult to achieve quick and convenient replacement of local components. When a functional component fails, the entire optical modem often needs to be disassembled, further reducing maintenance efficiency. Therefore, there is an urgent need to design a new communication optical modem structure that can overcome the problems of inconvenient installation and disassembly, low maintenance efficiency, etc. in the existing technology, realize rapid installation and assembly, and improve the practicality and reliability of the optical modem.

DETAILED DESCRIPTION
[0018] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.
[0019] Example 1 like Figures 1 to 4As shown, a communication optical modem that is easy to quickly install and disassemble includes an optical modem lower shell 1 and an upper cover 2. The bottom of the upper cover 2 is provided with a mounting post 3. The side wall of the mounting post 3 is fixed with an arc-shaped spring piece 5. The bottom of the arc-shaped spring piece 5 is connected to the mounting post 3. There is a gap between the top of the arc-shaped spring piece 5 and the mounting post 3. The inner wall of the optical modem lower shell 1 is fixed with a connecting block 4. The top of the connecting block 4 is provided with a plug hole 6. The plug hole 6 is located on the moving path of the mounting post 3. The side wall of the plug hole 6 is provided with a limiting groove 7. When the mounting post 3 is adapted to the plug-in hole 6, the arc-shaped spring piece 5 is normally located in the limiting groove 7, and the top of the arc-shaped spring piece 5 is against the inner top wall of the limiting groove 7. The mounting post 3 is rotated to connect the upper cover 2. The connecting block 4 is provided with a disassembly slide 10 on the side wall of the plug-in hole 6. The disassembly slide 10 extends to the top of the connecting block 4. The disassembly slide 10 is connected to the limiting groove 7. The arc-shaped spring piece 5 can slide out of the connecting block 4 by disassembling the slide 10, and the upper cover 2 is buckled on the top of the lower shell 1 of the optical modem. 3 carries the arc-shaped spring piece 5 and inserts it into the plug-in hole 6. The size of the plug-in hole 6 is smaller than that of the arc-shaped spring piece 5, so that the arc-shaped spring piece 5 will be squeezed and deformed. The arc-shaped spring piece 5 enters the plug-in hole 6 under the action of its own deformation. When the mounting column 3 is plugged into place, the arc-shaped spring piece 5 corresponds to the limiting groove 7, and the arc-shaped spring piece 5 resets and enters the limiting groove 7, so that the top of the arc-shaped spring piece 5 contacts the inner top wall of the limiting groove 7, thereby quickly connecting the lower shell 1 of the optical modem with the upper cover 2. When disassembling, rotate the mounting column 3, so that the arc-shaped spring piece 5 enters the disassembly slide 10 from the limiting groove 7. Since the disassembly slide 10 passes through the top of the connecting block 4 and moves the upper cover 2 away from the lower shell 1 of the optical modem, the arc-shaped spring piece 5 can be disengaged from the plug-in hole 6, and the upper cover 2 and the lower shell 1 of the optical modem can be disassembled without the help of tools such as screwdrivers, which greatly simplifies the installation and disassembly process. Compared with the traditional screw fastening method, it significantly shortens the installation and disassembly time. It is especially suitable for large-scale installation and emergency repair scenarios, and greatly improves the operating efficiency.
[0020] Example 2 Based on the first embodiment, Figures 1 to 4As shown, a driving rod 11 is slidably penetrated through the top of the mounting column 3, and a hexagonal groove 12 is provided on the top of the upper cover 2, and a hexagonal nut 13 is matched in the hexagonal groove 12. One end of the driving rod 11 is inserted into the hexagonal groove 12 and fixedly connected to the hexagonal nut 13. A circular groove 14 is provided on the top of the mounting column 3, and a guide groove 15 is provided on the inner wall of the circular groove 14. The end of the driving rod 11 away from the hexagonal nut 13 slides and fits into the circular groove 14. A guide block 16 is fixed on the side wall of the driving rod 11, and the guide block 16 slides and fits into the guide groove 15, so that the driving rod 11 and the mounting column 3 only have relative linear movement freedom, that is, the driving rod 11 and the mounting column 3 rotate synchronously. In order to facilitate the rotation of the mounting column 3 and complete the installation and disassembly operations, a driving rod 11 is provided on the mounting column 3. When the upper cover 2 and the optical modem lower shell 1 are installed together When the upper cover 2 and the lower shell 1 of the optical modem are stably installed together, the mounting post 3 will not rotate accidentally and cause an unstable connection. When disassembling, the optical modem is turned over to make the hexagonal nut 13 move downward under gravity. The driving rod 11 moves away from the mounting post 3 through the cooperation of the guide block 16 and the guide slot 15, so that the hexagonal nut 13 slides out of the hexagonal slot 12, and the rotational freedom of the mounting post 3 can be unlocked. By rotating the hexagonal nut 12 to drive the mounting post 3 to rotate, the arc-shaped spring piece 5 can be turned into the disassembly slot 10 to complete the disassembly of the cover 2 and the lower shell 1 of the optical modem.
[0021] Example 3 Based on the second embodiment, Figure 1 and Figure 3 As shown, a through hole 17 is formed through the bottom wall of the hexagonal groove 12, and the mounting column 3 is movable through the through hole 17. An upper limit piece 18 and a lower limit piece 19 are fixedly sleeved on the mounting column 3. The upper limit piece 18 contacts the bottom of the hexagonal groove 12, and the lower limit piece 19 contacts the bottom of the upper cover 2. The rotational connection of the mounting column 3 is completed by the joint action of the upper limit piece 18 and the lower limit piece 19. The rotational installation of the mounting column 3 can be completed without a bearing component, and the rotational installation of the mounting column 3 can be realized in a small space.
[0022] Example 4 Based on the third embodiment, Figures 1 to 4When the positioning slider 22 is located at one end of the arc positioning groove 21, the arc spring piece 5 slides from the limiting groove 7 into the disassembly slide 10, and the hexagonal nut 13 and the inner hexagonal groove 12 are in an interlaced state. When the positioning slider 22 is located at the other end of the arc positioning groove 21, the arc spring piece 5 is located in the limiting groove 7, and the hexagonal nut 13 is adapted to the inner hexagonal groove 12, thereby realizing accurate installation and reliable disassembly of the optical modem lower shell 1 and the upper cover 2. Specifically, during installation, the mounting post 3 is rotated to make the positioning slider 22 slide to the other end of the arc positioning groove 21 until the mounting post 3 cannot be rotated, and then the upper cover 2 is buckled with the optical modem lower shell 1 to complete the connection. At this time, the arc spring piece 5 can be smoothly inserted into the limiting groove When the upper cover 2 is removed, the upper cover 2 is directly removed from the upper cover 2 and the lower cover 2 is directly removed from the upper cover 2.
[0023] Furthermore, a damping sleeve 20 is provided on the fixing sleeve of the mounting column 3. The damping sleeve 20 is located between the upper limit plate 18 and the lower limit plate 19. The damping sleeve 20 is adapted in the through hole 17 by compression deformation interference fit, so that there is a large friction between the damping sleeve 20 and the upper cover 2. The position of the mounting column 3 can be locked by this friction force. After the installation is completed, the position of the mounting column 3 is locked by the cooperation of the hexagonal nut 13 and the hexagonal groove 12. During disassembly, the position of the mounting column 3 is locked by the friction force generated by the damping sleeve 20, so that the hexagonal nut 13 is against the top surface of the upper cover 1 and the hexagonal groove 12 is staggered. The hexagonal nut 13 will not accidentally deflect and cause the arc-shaped spring piece 5 to separate from the disassembly slide 10, thereby making the disassembly of the optical modem lower shell 1 and the upper cover 2 more accurate.
[0024] Example 5 Based on the fourth embodiment, Figure 1 and Figure 2As shown, the arc-shaped spring piece 5 includes an arc-shaped segment 8 and an abutting segment 9. The bottom and top of the arc-shaped segment 8 are respectively connected to the mounting column 3 and the abutting segment 9. The abutting segment 9 is parallel to the mounting column 3, so that the abutting segment 9 is arranged vertically, so that the top surface of the abutting segment 9 can well contact the inner top wall of the limiting groove 7, completing the reliable connection between the lower shell 1 and the upper cover 2 of the optical modem.
[0025] Furthermore, a prying opening 23 is provided on the side wall of the upper cover 2 near the inner hexagonal groove 12, and the prying opening 23 is connected to the inner hexagonal groove 12. When impurities enter the inner hexagonal groove 12 and the hexagonal nut 13 cannot fall out of the inner hexagonal groove 12, a pick is used to be inserted into the prying opening 23. The diameter of the upper limit plate 18 is smaller than the inscribed circle diameter of the hexagonal nut 13, so that a gap is formed between the edge of the hexagonal nut 13 and the bottom wall of the inner hexagonal groove 12. The pick is inserted into the gap to push the hexagonal nut 13 upwards, so that the hexagonal nut 13 is disengaged from the inner hexagonal groove 12, and the rotation of the mounting column 3 can be controlled to complete the installation and disassembly of the optical modem.
[0026] Example 6 Since the arc-shaped spring piece 5 has a certain amount of movable space in the limiting groove 7, the connection between the optical modem lower shell 1 and the upper cover 2 is unstable, so that there is a shaking space between the upper cover 2 and the optical modem lower shell 1. Therefore, based on the fifth embodiment, as shown in FIG. Figures 1 to 4 As shown, a T-shaped slide 24 is fixed on the side wall of the mounting column 3, and a T-shaped slot 25 is opened on the side wall of the plug-in hole 6. The T-shaped slot 25 passes through the top of the connecting block 4, so that the T-shaped slide 24 can slide smoothly into the T-shaped slot 25. When the arc-shaped spring piece 5 is adapted in the limiting slot 7, the T-shaped slide 24 is adapted in the T-shaped slot 25, thereby limiting the freedom of movement of the upper cover 2 in the horizontal direction. Through the cooperation of the arc-shaped spring piece 5 and the limiting slot 7, the freedom of movement of the upper cover 2 in the vertical direction is limited, thereby improving the connection stability between the lower shell 1 of the optical modem and the upper cover 2.
[0027] Example 7 When installing the optical modem lower housing 1 and the upper cover 2, it is necessary to make the T-shaped slide bar 24 slide accurately into the T-shaped slide groove 25. For this purpose, based on the sixth embodiment, as shown in FIG. Figures 1 to 4 As shown, a positioning hole 26 is provided on the top of the optical modem lower shell 1, and a positioning shaft 27 is fixed at the position of the upper cover 2 corresponding to the positioning hole 26. When the positioning shaft 27 is inserted into the positioning hole 26, the T-shaped slide 24 can smoothly slide into the T-shaped slide groove 25, thereby realizing quick and high-precision installation of the upper cover 2 and the optical modem lower shell 1.
