[0029] Refer to Figures 1-3, An embodiment provided by the present utility model: An optical fiber hub with a secondary fixing structure for connectors, including a protective shell 1, made of high-strength plastic material, which can effectively resist external impacts and environmental influences, and improve the service life of the hub. A sealing cover 2 is arranged on the top of the protective shell 1, and the sealing cover 2 and the protective shell 1 are quickly assembled through a buckle structure to ensure timely maintenance and replacement of internal components. A connection frame 3 is fixedly connected to one side of the protective shell 1, and a first clamping block 4 is fixedly connected inside the connection frame 3 for fixing the optical fiber connector to prevent the connector from loosening due to vibration or external force. A pull rod 5 is slidably connected inside the connection frame 3, and the clamping force of the clamping block can be adjusted according to actual needs, so as to better adapt to different specifications of optical fibers. A connecting rod 6 is slidably connected inside the pull rod 5, and the connecting rod 6 is rotatably connected inside the connection frame 3. A slider 7 is slidably connected inside the connection frame 3, and a second clamping block 8 is fixedly connected to the top of the slider 7, further enhancing the clamping stability and ensuring the accurate positioning of the optical fiber during connection. One end of the connecting rod 6 is slidably connected inside the slider 7, and a support column 9 is slidably connected inside the pull rod 5. The slider 7 is slidably connected to the outer wall of the support column 9. A first spring 10 is sleeved on the outer wall of the support column 9. The top end of the first spring 10 is fixedly connected to the bottom of the slider 7, and the bottom end of the first spring 10 is fixedly connected inside the pull rod 5, which is used to provide a certain elastic support, so that the slider 7 and the pull rod 5 can quickly reset, effectively absorb external force impacts, and prevent the instability of the optical fiber connector caused by vibration. A connection component is arranged inside the protective shell 1, and the connection component is used to connect the protective shell 1 and the sealing cover 2. A plurality of interfaces 11 are arranged inside the protective shell 1 for facilitating the access of optical fibers. A heat dissipation port 12 is opened inside the protective shell 1, which helps to keep the device in good working condition during long-term use.
[0030] Specifically, during the process of using this hub, when it is necessary to access the cable, first pull the pull rod 5, and the force applied will drive the internal connecting rod 6 to rotate inside the connection frame 3. Under the action of the force, the connecting rod 6 drives the slider 7 at one end to slide inside the connection frame 3. The movement of the slider 7 will cause the connection frame 3 connected to the top to displace, providing a larger access space. At this time, the movement between the slider 7 and the pull rod 5 will cause the first spring 10 to be compressed to a certain extent. After the cable is inserted into the interface 11, the user then releases the pull rod 5. At this time, the first spring 10 unloads the force and rebounds, driving the pull rod 5 and the second clamping block 8 to reset, so that the second clamping block 8 can effectively clamp the cable during the reset process. During clamping, the second clamping block 8 presses the cable against the first clamping block 4 for fixation, ensuring a firm connection at the joint. This not only improves the fixing effect of the hub and the cable connector, but also reduces signal interference caused by loosening, and improves the stability and reliability of the overall network connection.
[0031] Refer to Figure 1 , Figure 4 and Figure 5The connecting assembly includes a guide column 13 and a block 14, the guide column 13 is fixedly connected to the inside of the protective shell 1, and the block 14 is slidably connected to the outer wall of the guide column 13, the guide column 13 provides a stable guide for the sliding of the block 14, and can provide a certain limit for the second spring 15 to prevent the second spring 15 from deforming during the extension and contraction process, the outer wall of the guide column 13 is sleeved with a second spring 15, one end of the second spring 15 is fixedly connected to one side of the block 14, and the other end of the second spring 15 is fixedly connected to the inside of the protective shell 1, which plays a role of elastic support and provides the necessary reset force to ensure that the block 14 can automatically return to its position after operation, a fixed seat 16 is fixedly connected to the inside of the sealing cover 2, a connecting column 17 is fixedly connected to the bottom end of the fixing seat 16, and a ball head 18 is fixedly connected to the bottom end of the connecting column 17, the ball head 18 contacts with the block 14, and through the arc surface of the ball head 18, an extrusion force is applied to it when it contacts with the block 14, so that the block 14 moves accordingly, thereby locking and disassembling the sealing cover 2.
[0032] Specifically, when the hub needs to be disassembled and maintained, the sealing cover 2 is first attached to the top of the protective shell 1, so that the ball head 18 inside the sealing cover 2 can slide smoothly into the protective shell 1 and contact the block 14 inside the protective shell 1. After contacting the block 14, the block 14 moves due to the force, and at the same time, the second spring 15 on one side is squeezed to gradually shrink. When the sealing cover 2 is completely closed above the protective shell 1, the ball head 18 moves to the bottom of the block 14, and rebounds through the second spring 15 to unload the force, thereby pushing the block 14 to reset, so that it is stuck at the top of the ball head 18, to ensure that the sealing cover 2 is firmly installed.
[0033] Reference Figure 1 , Figure 4 and Figure 5 The outer wall of the connecting column 17 is slidably connected with a sliding column 19, and the bottom end of the sliding column 19 is fixedly connected with a conical column 20. The conical column 20 is conical in shape, and its inclined surface is convenient for squeezing the block 14, so that the block 14 shrinks, thereby releasing the ball head 18 and releasing the fixation. The outer wall of the sliding column 19 is fixedly connected with a lever 21, and the lever 21 is slidably connected to the inside of the sealing cover 2, so that the operator can control the movement of the sliding column 19 by simply pressing, thereby improving the convenience of operation.
[0034] Specifically, when disassembling, the user only needs to press the lever 21. After the lever 21 is stressed, it drives the sliding column 19 to move on the outer wall of the connecting column 17. After the sliding column 19 is stressed, it drives the conical column 20 connected to the bottom end to move. During the movement, the conical column 20 continues to squeeze the clamping block 14, causing the clamping block 14 to contract, thereby releasing the ball head 18 and releasing the fixation. Furthermore, the user can conveniently remove the sealing cover 2 from above the protective case 1, thus achieving the effect of rapid disassembly and assembly of the hub, facilitating the maintenance or replacement of the electronic components inside the hub, and improving the usage efficiency of the hub.
[0035] Working principle: When a cable needs to be connected during the use of this hub, first pull the pull rod 5, and its stress drives the connecting rod 6 connected inside to rotate inside the connecting frame 3. At the same time, the connecting rod 6 drives the slider 7 at one end to slide inside the connecting frame 3 under stress. The slider 7 drives the connecting frame 3 connected to the top to move under stress. The movements of the slider 7 and the pull rod 5 will cause the first spring 10 between them to be compressed to a certain extent. At this time, insert the cable into the interface 11, and then release the pull rod 5 to allow the first spring 10 to unload and rebound, thereby driving the pull rod 5 and the second clamping block 8 to return to their original positions. During the reset process, the second clamping block 8 clamps the cable and presses it against the first clamping block 4 for fixation, thus achieving the effect of effectively fixing the joint between the hub and the cable. When the hub needs to be disassembled and maintained, first fit the sealing cover 2 above the protective case 1, so that the ball head 18 inside the sealing cover 2 slides into the protective case 1 and contacts the clamping block 14 inside the protective case 1, causing the clamping block 14 to move under stress and simultaneously squeeze the second spring 15 on one side of it, causing it to contract. When the sealing cover 2 is completely closed above the protective case 1, at this time, the ball head 18 moves to the bottom of the clamping block 14, and the second spring 15 unloads and rebounds, thereby pushing the clamping block 14 to return to its original position and making it stuck at the top of the ball head 18 for fixation to complete the installation. When disassembling, only press the lever 21, and its stress drives the sliding column 19 to move on the outer wall of the connecting column 17. The sliding column 19 drives the conical column 20 connected to the bottom end to move under stress. During the movement of the conical column 20, it squeezes the clamping block 14, causing the clamping block 14 to contract, and then releases the ball head 18. Subsequently, the sealing cover 2 can be removed from above the protective case 1, thus achieving the effect that the hub can be quickly disassembled and assembled for easy maintenance.
[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
