Description

Technical Field

[0001] This utility model relates to the field of optical modem technology, and more specifically to an optical modem structure in a PON system that facilitates the display of network disconnection information. Background Technology

[0002] An optical modem, also known as a single-port optical transceiver or optical modem, is a three-piece fiber optic transmission device developed for specific user environments. In a PON (Passive Optical Network) system, the optical modem is a key terminal device at the user end, responsible for photoelectric conversion, protocol processing, and management functions, enabling users to access the Internet and other services via fiber optics. This device uses large-scale integrated chips, featuring simple circuitry, low power consumption, high reliability, complete alarm status indication, and comprehensive network management functions. After fiber optic cable is installed in the home, it is usually directly connected to the weak current box; therefore, the optical modem needs to be installed inside the weak current box, and the network signal is distributed to each room via network cables within the weak current box.

[0003] The existing devices have the following problems when in use. First, the network indicator lights of some existing optical modems are located on the back of the optical modem. When the optical modem is fixed in the weak current box with bolts or other means, the network indicator lights of the optical modem are easily blocked by the optical modem, making it impossible for personnel to observe the network status directly. This is not conducive to timely observation and maintenance when the network fails. Second, when the optical modem is fixed in the weak current box with bolts or other means, the back of the optical modem is far away from personnel, which is not conducive to personnel plugging and unplugging network cables for maintenance.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Appendix Figures 1-5This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0023] See attached document Figures 1-5 This solution provides a PON system optical modem structure that facilitates the indication of network disconnection information. It includes an optical modem body 1, a network signal light 2 on the rear side of the optical modem body 1, and a support component below the optical modem body 1. The support component includes a base 3, a rotating mechanism, an adjusting mechanism, and a limiting mechanism. The base 3 is located directly below the optical modem body 1, the rotating mechanism is located above the base 3, the adjusting mechanism is located above the rotating mechanism, and the limiting mechanism is located on the rotating mechanism.

[0024] Specifically, the rotating mechanism includes a slide 4, a slider 5, and a support frame 6. The slide 4 is located on the top surface of the base 3. There are two sliders 5, which are located inside the base 3 and are slidably connected to the inner wall of the slide 4. The support frame 6 is located above the sliders 5, and the tops of the two sliders 5 are fixedly connected to the bottom surface of the same support frame 6. Two first connecting blocks 7 are fixedly connected to the top surface of the support frame 6. The first connecting blocks 7 have through holes. The two first connecting blocks 7 are movably connected to the same rotating shaft 8. Two second connecting blocks 9 are arranged around the rotating shaft 8. The second connecting blocks 9 have through holes. The rotating shaft 8 is movably connected to the second connecting blocks 9, and the second connecting blocks 9 are fixedly connected to the bottom surface of the optical modem body 1.

[0025] In this embodiment, the personnel can rotate the slide 4 so that the slider 5 slides in the slide 4. The slider 5 rotates in the slide 4, which drives the support frame 6 to rotate. The rotation of the support frame 6 drives the first connecting block 7 to rotate. The first connecting block 7 drives the second connecting block 9 to rotate through the rotating shaft 8. The second connecting block 9 drives the optical modem body 1 to rotate longitudinally.

[0026] Specifically, the adjustment mechanism includes a rotating column 12, a first bevel gear 13, and a second bevel gear 14. The rotating column 12 is rotatably connected to the top surface of the base 3. The first bevel gear 13 is located on the periphery of the rotating column 12. The rotating column 12 passes through the top surface of the support frame 6 and extends to the outside. The rotating column 12 is fixedly connected to the support frame 6. The first bevel gear 13 is fixedly connected to the periphery of the rotating column 12. The second bevel gear 14 meshes with the first bevel gear 13. The second bevel gear 14 is located to the upper left of the first bevel gear 13. The second bevel gear 14 is fixedly connected to the periphery of the rotating shaft 8. The inner wall of the second connecting block 9 is provided with several clearance grooves 10. The inner wall of the rotating shaft 8 is fixedly connected with two sets of guide blocks 11. The guide blocks 11 are arranged in a circular array. The guide blocks 11 are located in the corresponding clearance grooves 10. The guide blocks 11 abut against the right inner wall of the corresponding clearance grooves 10. Both ends of the rotating shaft 8 are provided with baffles 23.

[0027] In this embodiment, personnel can change the position of the rotating shaft 8 by moving the baffle 23, thereby changing the position of the second bevel gear 14 and the meshing relationship between the second bevel gear 14 and the first bevel gear 13.

[0028] Specifically, the limiting mechanism includes a socket 15, a rod 16, and a limiting block 17. Several sockets 15 are opened on the top surface of the base 3 and are arranged at equal intervals. The limiting block 17 is fixedly connected to the side wall of the slider 5 located on the right side. The rod 16 passes through the limiting block 17 and is inserted into the corresponding socket 15. The top surface of the limiting block 17 is provided with a placement groove 18. A first tension spring 20 is provided on the inner wall of the placement groove 18. The first tension spring 20 is sleeved on the periphery of the rod 16. One end of the placement groove 18 is fixedly connected to the bottom surface of the inner wall of the first tension spring 20. A connecting ring 19 is fixedly connected to the periphery of the rod 16. The connecting ring 19 is located above the limiting block 17. The other end of the first tension spring 20 is fixedly connected to the bottom surface of the connecting ring 19.

[0029] In this embodiment, personnel can adjust the relationship between the limiting block 17 and the base 3 by adjusting the position of the insertion rod 16, thereby facilitating personnel to change the limiting state of the slider 5 and the base 3.

[0030] Specifically, a third connecting block 21 is provided on one side of the first connecting block 7 on the left. The third connecting block 21 is fixedly connected to the bottom surface of the optical modem body 1. A through hole is provided on the third connecting block 21. The third connecting block 21 is movably connected to the rotating shaft 8. A second tension spring 22 is fixedly connected to the side of the third connecting block 21 away from the first connecting block 7. The second tension spring 22 is sleeved on the periphery of the rotating shaft 8. One end of the second tension spring 22 is fixedly connected to the side wall of the third connecting block 21, and the other end of the second tension spring 22 is fixedly connected to the side wall of the corresponding baffle 23.

[0031] In this embodiment, when the second tension spring 22 is in the retracted state, the baffle 23 fixed to it will move to the right, thereby causing the rotating shaft 8 to move to the right, so that the second bevel gear 14 remains engaged with the first bevel gear 13, thereby limiting the angle of lateral rotation of the optical modem body 1.

[0032] Specifically, two symmetrically arranged mounting blocks 24 are fixedly connected to the periphery of the base 3, and mounting holes are provided on the mounting blocks 24.

[0033] In this embodiment, personnel can install the device by inserting bolts into the through holes of the mounting block 24.

[0034] The working principle and usage process of this utility model are as follows: During installation, the operator first places the base 3 inside the low-voltage box, then inserts the bolt into the through hole of the mounting block 24, and installs the mounting block 24 inside the low-voltage box. At this time, the operator lifts the plug rod 16, which moves upward and drives the connecting ring 19 to move upward. The upward movement of the connecting ring 19 stretches the first tension spring 20. At this time, the plug rod 16 moves out of the corresponding plug hole 15. The operator rotates the slider 5, which rotates in the slide groove 4, causing the support frame 6 to rotate. The rotation of the support frame 6 causes the first connecting block 7 to rotate. The first connecting block 7 drives the second connecting block 9 to rotate through the rotating shaft 8. The second connecting block 9 drives the optical modem body 1 to rotate longitudinally. At the same time, the rotation of the support frame 6 drives the rotating column 12 to rotate. The rotating column 12 drives the first bevel gear 13 fixed to it to rotate. The first bevel gear 13 drives the second bevel gear 14 meshing with it to rotate. The second bevel gear 14 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the first bevel gear 14 to rotate. When the guide block 11 rotates, the guide block 11 will drive the second connecting block 9 to rotate because the clearance groove 10 is inside the guide block 11. This will cause the second connecting block 9 to drive the base 3 to rotate laterally around the rotating shaft 8. At this time, the optical modem body 1 will rotate both longitudinally and laterally. When the optical modem body 1 is adjusted to a suitable angle, the person releases the plug rod 16. The stretched first tension spring 20 retracts downward, causing the connecting ring 19 to move downward. The connecting ring 19 drives the plug rod 16 to insert downward into the corresponding socket 15. At this time, the plug rod 16 limits the limit block 17 and the support frame 6. At this time, the slider 5 and the support frame 6 no longer rotate. The longitudinal rotation angle of the optical modem body 1 is limited. The support frame 6 is limited, which limits the rotating column 12. The rotating column 12 is limited, which limits the first bevel gear 13. The first bevel gear 13 is limited, which prevents the second bevel gear 14 from rotating. Therefore, the rotating shaft 8 no longer rotates, and the lateral rotation angle of the optical modem body 1 is limited.

[0035] When the operator wants to rotate the optical modem body 1 laterally, they pull the baffle 23 near the second tension spring 22 away from it. The baffle 23 stretches the second tension spring 22, and simultaneously moves the rotating shaft 8. This causes the second bevel gear 14 to move to the left, and the guide block 11 to slide to the left within the clearance groove 10. At this point, the second bevel gear 14 is no longer meshed with the first bevel gear 13. The operator then rotates the baffle 23, which in turn rotates the rotating shaft 8. This rotation of the rotating shaft 8 then rotates the guide block 11, which in turn rotates the second connecting block 9. The rotation causes the second connecting block 9 to drive the base 3 to rotate laterally around the rotating shaft 8. When the base 3 rotates to a suitable angle, the personnel release the baffle 23. The stretched second tension spring 22 rebounds and drives the corresponding baffle 23 to move to the right. The baffle 23 drives the rotating shaft 8 to move to the right. The rotating shaft 8 drives the guide block 11 to move to the right in the clearance groove 10. At the same time, the rotating shaft 8 drives the second bevel gear 14 to move to the right, so that the second bevel gear 14 meshes with the first bevel gear 13 again. The second bevel gear 14 is limited so that the first bevel gear 13 cannot rotate. Therefore, the rotating shaft 8 no longer rotates, and the angle of lateral rotation of the optical modem body 1 is limited.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
