Description

Technical Field

[0001] This utility model relates to the field of communication engineering technology, and more specifically, it relates to an optical fiber transceiver for communication engineering. Background Technology

[0002] Telecommunications engineering refers to the engineering field that uses electronic and communication technologies to design, construct, operate, and maintain various communication equipment and networks. In the construction, maintenance, and emergency repair of optical fiber communication networks, it is often necessary to quickly and orderly reel in and unleash optical fibers or lightweight optical cables, requiring the use of fiber optic retractors. However, existing fiber optic retractors are susceptible to damage from accidental impacts after the fiber is reeled in, lacking suitable safety protection mechanisms. Furthermore, the locking operation of the safety protection mechanism in the reeled state is cumbersome, lacking suitable and convenient locking mechanisms. Additionally, during the rewinding process, the fiber is prone to accumulating at certain points, lacking suitable and efficient guiding mechanisms. Utility Model Content

[0007] The present invention is further configured such that the transmission mechanism includes a first bevel gear and a second bevel gear, the first bevel gear is mounted on the drive shaft, the second bevel gear is mounted on the rotating shaft, and the first bevel gear and the second bevel gear are meshed to realize drive transmission.

[0008] The present invention is further configured such that a sealing cover is hinged to the top of the rear end face of the support plate corresponding to the transmission mechanism, a first mounting hole is provided on the sealing cover, and a second mounting hole is provided on the rear end face of the fixing plate corresponding to the first mounting hole. The first mounting hole and the second mounting hole are connected by bolts to protect the transmission mechanism.

[0009] The present invention is further configured such that guide rods are symmetrically arranged inside the T-shaped seat, and guide holes are symmetrically opened on the T-shaped seat corresponding to the guide rods, so as to guide the sliding of the T-shaped seat.

[0010] The present invention is further configured such that an adjusting rod is rotatably provided on the support plate, an adjusting motor is connected to the rear end of the adjusting rod, an adjusting hole is provided on the T-shaped seat corresponding to the adjusting rod, and the adjusting rod and the adjusting hole are threadedly connected to realize reciprocating sliding drive.

[0011] The present invention is further configured such that a T-shaped locking rod is rotatably provided on the U-shaped protective plate, and a locking plate is provided on the L-shaped protective plate corresponding to the T-shaped locking rod. A through groove is provided on the locking plate corresponding to the T-shaped locking rod for easy locking in the closed state.

[0012] The present invention is further provided with anti-slip rubber sleeves symmetrically provided on the T-shaped locking rod corresponding to the locking plate to ensure the locking effect.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an optical fiber transceiver for communication engineering, which has the following advantages:

[0015] 1. Through the design of U-shaped and L-shaped protective plates, the U-shaped and L-shaped protective plates hinged on the bottom plate can close together to form a protective cover on the top and sides, which isolates the winding roller and the wound optical fiber inside. This can effectively prevent collisions with external foreign objects, dust intrusion, and accidental contact by personnel, thereby ensuring the cleanliness and safety of optical fiber products and improving the reliability and safety of the equipment during transportation, storage, or when operations are suspended.

[0016] 2. The T-shaped seat design, driven by a motor-driven adjusting rod, allows the threaded T-shaped seat to slide smoothly and reciprocally along the adjusting groove on the base plate. The support rod and guide sleeve fixed to the T-shaped seat move synchronously, thus guiding the optical fiber evenly along the axial direction on the take-up roller in real time and with precision. This dynamic guiding mechanism effectively avoids problems such as overlapping, scattering, or edge collapse of the optical fiber during take-up, ensuring a neat and tight roll shape. This facilitates subsequent optical disc cable laying or construction, while also reducing potential fiber damage caused by poor cable laying.

[0017] 3. The T-shaped locking rod design allows the U-shaped and L-shaped protective plates to be closed together. By rotating the T-shaped locking rod on the U-shaped plate, it passes through the locking slot in the L-shaped plate, and the T-head provides axial positioning. The anti-slip rubber sleeve on the T-shaped locking rod increases frictional resistance, preventing it from loosening due to vibration or other reasons. This locking structure effectively prevents the protective plates from accidentally popping open due to equipment movement or external interference, maintaining the continuity of protection.

[0028] In this embodiment, the control device has its own control system. The drive motor 7 is started and installed at the bottom of the fixed plate 5 through its own connecting plate. The drive motor 7 drives the drive shaft 6 to rotate. The drive shaft 6 and the rotating shaft 3 are connected by a transmission mechanism to realize the overall rotation adjustment of the rotating shaft 3 and the take-up roller 4, and realize the fiber take-up and take-up adjustment on the take-up roller 4. During the take-up and take-up process, the T-shaped seat 11 slides back and forth relative to the adjustment groove 10. The guide sleeve 13 on the upper support rod 12 of the T-shaped seat 11 guides and adjusts the fiber take-up and take-up.

[0029] More specifically, after the optical fiber is retracted, the U-shaped protective plates 8 and L-shaped protective plates 9 on both sides are hinged and closed to provide safety protection for the retracted optical fiber.

[0030] Please see Figures 2-4 As one embodiment of the transmission mechanism: the transmission mechanism includes a first bevel gear 14 and a second bevel gear 15. The first bevel gear 14 is mounted on the drive shaft 6, and the second bevel gear 15 is mounted on the rotating shaft 3. The first bevel gear 14 and the second bevel gear 15 are meshed. A sealing cover 16 is hinged to the top of the rear end face of the support plate 2 corresponding to the transmission mechanism. A first mounting hole 17 is provided on the sealing cover 16. A second mounting hole 18 is provided on the rear end face of the fixing plate 5 corresponding to the first mounting hole 17. The first mounting hole 17 and the second mounting hole 18 are connected by bolts.

[0031] Specifically, the first bevel gear 14 and the second bevel gear 15 of the transmission mechanism mesh to achieve stable transmission between the rotating shaft 3 and the drive shaft 6. The sealing cover 16 is hinged to the rear side of the support plate 2 to provide safety protection for the transmission mechanism. After the hinge is closed, the first mounting hole 17 and the second mounting hole 18 are aligned, and the bolts pass through and are tightened to fix it.

[0032] Please see Figures 2-5 As one embodiment of the T-shaped seat 11: the T-shaped seat 11 is symmetrically provided with guide rods 19 inside, and guide holes 20 are symmetrically opened on the T-shaped seat 11 corresponding to the guide rods 19. An adjusting rod 21 is rotatably provided on the support plate 2. An adjusting motor 22 is connected to the rear end of the adjusting rod 21. An adjusting hole 23 is opened on the T-shaped seat 11 corresponding to the adjusting rod 21. The adjusting rod 21 and the adjusting hole 23 are threadedly connected.

[0033] Specifically, when the T-shaped seat 11 slides relative to the adjustment groove 10, the guide rod 19 and the guide hole 20 cooperate to guide it. The control device has its own control system, which starts the adjustment motor 22. The adjustment motor 22 is installed on the support plate 2 through its own connecting plate. The adjustment motor 22 drives the adjustment rod 21 to rotate. The adjustment rod 21 and the adjustment hole 23 are threaded together to realize reciprocating sliding drive.

[0034] Please see Figure 2 As one implementation method for protective locking: a T-shaped locking rod 24 is rotatably provided on the U-shaped protective plate 8, a locking plate 25 is provided on the L-shaped protective plate 9 corresponding to the T-shaped locking rod 24, a through groove 26 is opened on the locking plate 25 corresponding to the T-shaped locking rod 24, and anti-slip rubber sleeves 27 are symmetrically provided on the T-shaped locking rod 24 corresponding to the locking plate 25.

[0035] Specifically, the U-shaped protective plate 8 and the L-shaped protective plate 9 are hinged and closed to the mating state. Before closing, the T-shaped locking rod 24 is rotated to the direction of the corresponding through groove 26 of the locking plate 25. After the mating is closed, the T-shaped locking rod 24 is rotated, and the T-shaped locking rod 24 and the locking plate 25 are mated. The anti-slip rubber sleeve 27 is in contact with the locking position to ensure anti-slip contact and to ensure a certain degree of locking effect.

[0036] In summary, the overall equipment is in use:

[0037] When the fiber is being wound up or down, the control device has a built-in control system that starts the drive motor 7 and the adjustment motor 22. The drive motor 7 drives the drive shaft 6 to rotate. The drive shaft 6 and the rotating shaft 3 are connected by the meshing of the first bevel gear 14 and the second bevel gear 15 to achieve stable transmission and realize the overall rotation of the take-up roller 4 to wound up or down the fiber. During the winding up or down process, the adjustment motor 22 drives the adjustment rod 21 to rotate back and forth. The adjustment rod 21 and the adjustment hole 23 are threaded together. The T-shaped seat 11 slides relative to the adjustment groove 10. The guide rod 19 and the guide hole 20 cooperate to guide the reciprocating sliding. The guide sleeve 13 guides the fiber winding up or down process to avoid serious accumulation at the end position.

[0038] When the transmission mechanism is in the protection state, the sealing cover 16 is hinged to the support plate 2 and closed. The sealing cover 16 and the fixing plate 5 cooperate to achieve safety protection for the transmission mechanism. After the hinge is closed, the first mounting hole 17 and the second mounting hole 18 are aligned, and the bolts are passed through and tightened to achieve safety protection for the positions of the first bevel gear 14 and the second bevel gear 15.

[0039] When the fiber optic cable is in the protection state, after the fiber optic cable is retracted, the U-shaped protection plates 8 and L-shaped protection plates 9 on both sides are hinged and closed. Before hinged, the T-shaped locking rod 24 is rotated to the corresponding through slot 26 position. After the T-shaped locking rod 24 is inserted through the locking plate 25, the T-shaped locking rod 24 is rotated. The anti-slip rubber sleeve 27 on the T-shaped locking rod 24 and the locking plate 25 make anti-slip contact, thereby achieving the closed state and locking.
