Description

Technical Field

[0001] This invention relates to the field of optical fiber repair technology, specifically to a skin reinforcement and repair device for wound optical fibers. Background Technology

[0002] The spiral-wound fiber optic sheath reinforcement and repair device is a specialized device used to repair and reinforce damaged fiber optic sheaths. It is mainly used in outdoor fiber optic line maintenance and repair scenarios. It is fixed to the outside of the fiber optic cable in a spiral winding manner, providing all-round protection and repairing damaged sheaths, preventing further damage to the fiber optic cable, and extending its service life.

[0003] Patent publication number CN210323514U relates to a body, side members, auxiliary members, a base plate, a flip plate, a silicone pad, and an inner hole. The body is a rectangular plate structure made of leather. The inner bottom of the side members is fixedly connected to both sides of the body. The auxiliary members are made of rubber and are installed inside the side members by adhesive bonding. The base plate is made of rubber and is installed at the bottom of the body by adhesive bonding. The side members are placed on both sides of the body so that after the auxiliary members are installed on the inner side of the side members, the body can be connected together through the side members on both sides. When the device is wound around the outside of the optical fiber, the side members on both sides of the body can be connected together, so that the body can be securely wound and fixed to the outside of the optical fiber, thereby reinforcing and protecting the optical fiber.

[0004] In the aforementioned patent, the side pieces on both sides of the main body can be connected together, so that the main body can be securely wrapped and fixed to the outside of the optical fiber, thereby reinforcing and protecting the optical fiber. However, there are still problems. It is difficult to effectively ensure that the machine and the optical fiber can be tightly bonded during bonding, and it is also difficult to ensure that the repair fluid is connected to the optical fiber while fixing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a skin reinforcement and repair device for wound optical fibers, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a skin reinforcement and repair device for wound optical fibers, comprising a frame, a release device for quickly wrapping the entire optical fiber and quickly releasing the repair fluid, the release device further comprising;

[0007] A handle is provided on the right side of the frame, and a limiting ring is slidably installed inside the frame.

[0008] The elastic telescopic plate has a fixed end that is fixedly installed on the left side of the frame, a baffle that is fixedly installed on the fixed end of the elastic telescopic plate, and a movable plate that is slidably installed on the free end of the elastic telescopic plate. The movable plate is used to detect whether the frame is in close contact with the surface of the optical fiber.

[0009] A cylindrical rod is fixedly inserted through the back of the handle. A pull rod is slidably installed inside the cylindrical rod. A three-bar linkage is fixedly installed on the right side of the frame. The three-bar linkage consists of a fixed rod, a middle rod, and a top rod. The three-bar linkage is used to prevent accidental contact of the moving plate, which would cause the repair fluid to be wasted and leak out. When the frame comes into contact with the surface of the optical fiber, the limiting ring will slide. When the limiting ring slides to the point where the frame and the surface of the optical fiber are in contact, the contact rod will move. When the contact rod moves, it will disengage from the baffle, thereby releasing the limiting of the moving plate.

[0010] According to the above technical solution, the release device also includes a transmission plate and a contact rod. The transmission plate is fixedly installed on the right side of the moving plate, and the contact rod is fixedly installed on the left side of the moving plate. When the limit of the moving plate is released, the free end of the elastic telescopic plate will continue to push the moving plate to avoid the repair fluid inside the handle from flowing out when the frame and the optical fiber are just attached, and to avoid the frame and the optical fiber from being misaligned and wasting.

[0011] According to the above technical solution, the pulling rod is in contact with the three-bar linkage, the transmission plate is in contact with the pulling rod, and a first spring is provided between the cylindrical rod and the pulling rod;

[0012] The handle is equipped with an inspection device for detecting the content of repair fluid inside the handle and a filling device for quickly filling the repair fluid. When the moving plate moves, it will release the channel between the frame and the handle. If there is a misalignment, the transmission plate cannot move with the pull rod, thus providing secondary protection and reducing the occurrence and frequency of leakage.

[0013] According to the above technical solution, the detection device includes a fixed block, a slider, and a limiting block. The fixed block is fixedly installed on the inner wall of the handle near the end of the frame. The slider is slidably installed on the side of the fixed block away from the frame. The limiting block is fixedly installed on the side of the slider near the inner wall of the handle. When the repair fluid inside the handle is gone, the cover plate will move to the end of the handle near the frame. At the same time, when the cover plate moves, it will drive the elastic telescopic block to move. When the elastic telescopic block moves, it will contact the slider on the fixed block.

[0014] According to the above technical solution, the detection device further includes a moving block, a sealing column, an elastic telescopic block, a tension spring, and a cover plate. The moving block is slidably installed on the side of the fixed block away from the frame. The sealing column is slidably installed on the end of the moving block away from the slider. One end of the tension spring is fixedly installed on the side of the fixed block away from the frame. The cover plate is fixedly installed on the other end of the tension spring. The fixed end of the elastic telescopic block is slidably installed on the side of the cover plate close to the fixed block. When the elastic telescopic block contacts the slider, it will cause the slider to move away from the sealing column. When the slider moves, it will drive the limiting block to move. When the limiting block moves, it will release the limiting of the moving block.

[0015] According to the above technical solution, the free end of the elastic telescopic block is in contact with the slider, the free end of the elastic telescopic block is in contact with the sealing column, the limiting block is in contact with the moving block, and a through hole is provided in the middle part of the cover plate. When the limiting of the moving block is released, the moving block will move to the middle. When the moving block moves to the middle, it will release the limiting of the sealing column. At the same time, when the limiting of the sealing column is released, the elastic telescopic block will push the sealing column.

[0016] According to the above technical solution, the filling device includes a connecting plate, a rotating plate, a driving plate, a limiting plate, a circular plate, a retaining ring, and a retaining block. One end of the connecting plate is fixedly installed on the fixed end of the elastic telescopic block. The rotating plate is rotatably installed on the other end of the connecting plate. The driving plate is slidably installed inside the through hole of the cover plate. The limiting plate is rotatably installed on the side of the driving plate away from the fixed block. The circular plate is slidably installed on the side of the cover plate away from the frame. The retaining ring is fixedly installed on the side of the cover plate away from the connecting plate. The retaining block is slidably installed on the side of the handle away from the frame. When the elastic telescopic block moves outward, the worker can pull the elastic telescopic block outward and then lift the elastic telescopic block upward. When the elastic telescopic block moves upward, it will drive the cover plate to move.

[0017] According to the above technical solution, the limiting plate is in contact with the circular plate, and the retaining ring is in contact with the retaining block. When the moving plate moves downward, it will drive the limiting plate downward. When the limiting plate moves downward, it will release the limiting of the circular plate. When the limiting of the circular plate is released, the worker can pull the circular plate open.

[0018] This invention provides a device for reinforcing and repairing the outer sheath of wound optical fibers. It has the following beneficial effects:

[0019] (1) This invention avoids the leakage of repair fluid inside the handle when the frame and the optical fiber are just attached, prevents the waste of repair fluid caused by misalignment, and the transmission plate cannot be linked with the pull rod when not attached, reducing the leakage situation and frequency. It can also reduce the staff's observation of the degree of attachment and speed up the repair process. It also reduces the complicated steps that the staff need to repeatedly check, and makes the use of repair fluid more precise and convenient.

[0020] (2) When the repair fluid is depleted, the elastic telescopic block pushes the sealing column through a series of interconnected components, intuitively prompting the staff to replenish the repair fluid. The staff does not need to manually squeeze the handle. The device can complete the fluid shortage detection and warning actions through its own structure, simplifying the operation process and thus reducing the difficulty of operation and improving automation.

[0021] (3) This invention only requires the staff to complete the simple operation of "pulling out the sealing column and pulling and lifting the elastic telescopic block" to automatically drive the subsequent components to complete the limit release action. There is no need to manually operate multiple independent components, which reduces the complexity of operation. By pulling the card block to limit the card ring, the position of the relevant components can be fixed to avoid the components from shifting during the replenishment of repair fluid. Then, push the sealing column to complete the filling. The whole process is smooth and stable, which significantly improves the speed of replenishing repair fluid. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-7 One embodiment of the present invention is: a skin reinforcement and repair device for wound optical fiber, including a frame 1, a release device for quickly wrapping the entire optical fiber and quickly releasing the repair fluid, including a release device, the release device further including;

[0032] Handle 2 is located on the right side of frame 1, and limit ring 3 is slidably installed inside frame 1;

[0033] The elastic telescopic plate 401 has a fixed end that is fixedly installed on the left side of the frame 1. A baffle 402 is fixedly installed on the fixed end of the elastic telescopic plate 401. A movable plate 403 is slidably installed on the free end of the elastic telescopic plate 401. The movable plate 403 is used to detect whether the frame 1 is in close contact with the surface of the optical fiber.

[0034] A cylindrical rod 405 is fixedly inserted through the back of the handle 2. A pull rod 406 is slidably installed inside the cylindrical rod 405. A three-link rod 407 is fixedly installed on the right side of the frame 1. The three-link rod 407 consists of a fixed rod, a middle rod, and a top rod. The three-link rod 407 is used to prevent the moving plate 403 from being accidentally touched, which would cause the repair fluid to be wasted and leak out, thereby reducing the occurrence and frequency of leakage. It can also reduce the need for staff to observe the fit, speed up the repair process, and reduce the complicated steps that staff need to repeatedly check. In addition, it can make the use of repair fluid more precise and convenient.

[0035] The release device also includes a transmission plate 404 and a contact rod 408. The transmission plate 404 is fixedly installed on the right side of the moving plate 403, and the contact rod 408 is fixedly installed on the left side of the moving plate 403. When the limit of the moving plate 403 is released, the free end of the elastic telescopic plate 401 will continue to push the moving plate 403, so as to prevent the repair fluid inside the handle 2 from flowing out when the frame 1 is just attached to the optical fiber, and to prevent the frame 1 and the optical fiber from being misaligned, resulting in waste.

[0036] Pull rod 406 contacts the three-link 407, transmission plate 404 contacts pull rod 406, and a first spring is provided between cylindrical rod 405 and pull rod 406. When moving plate 403 moves, it will release the channel between frame 1 and handle 2. When there is a misalignment, transmission plate 404 cannot move with pull rod 406, thus providing secondary protection and reducing the occurrence and frequency of leakage.

[0037] In this embodiment, during operation: the operator fills the inside of the handle 2 with repair fluid, holds the handle 2 and presses the frame 1 against the surface of the optical fiber. When the frame 1 contacts the surface of the optical fiber, the limiting ring 3 slides. When the limiting ring 3 slides to the point where the frame 1 is in contact with the surface of the optical fiber, the contact rod 408 moves. When the contact rod 408 moves, it disengages from the baffle 402, thereby releasing the limiting of the moving plate 403. After the limiting of the moving plate 403 is released, the free end of the elastic telescopic plate 401 will continue to push the moving plate 403 to prevent the repair fluid inside the handle 2 from flowing out when the frame 1 is just in contact with the optical fiber.

[0038] To avoid misalignment between the frame 1 and the optical fiber, which would lead to waste, and when the surface of the frame 1 and the optical fiber are tightly bonded, the moving plate 403 will move the transmission plate 404 when it moves. When the transmission plate 404 moves, it will contact the pull rod 406 inside the cylindrical rod 405. When the frame 1 is completely bonded to the optical fiber, the worker will pull the pull rod 406 away from the handle 2. When the pull rod 406 is pulled out, it will move the transmission plate 404. When the transmission plate 404 moves, it will move the moving plate 403. When the moving plate 403 moves, it will release the passage between the frame 1 and the handle 2.

[0039] When there is a misalignment, the transmission plate 404 cannot move with the pull rod 406, thus providing secondary protection and reducing the occurrence and frequency of leakage. When the pull rod 406 is pulled, it will move to the side of the three-link 407 away from the handle 2. When the operator releases the handle, the three-link 407 will limit the pull rod 406. When the repair fluid is no longer needed, the operator will rotate the middle rod of the three-link 407 to release the limit of the pull rod 406.

[0040] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the handle 2 is provided with an inspection device for detecting the content of repair fluid inside the handle 2 and a filling device for quickly filling repair fluid inside the handle 2. The inspection device includes a fixing block 501, a slider 502 and a limiting block 503. The fixing block 501 is fixedly installed on the inner wall of the handle 2 near the end of the frame 1. The slider 502 is slidably installed on the side of the fixing block 501 away from the frame 1. The limiting block 503 is fixedly installed on the side of the slider 502 near the inner wall of the handle 2. Without the need for the operator to manually squeeze the handle 2, the device can complete the related actions of fluid shortage detection and prediction through its own structure, simplifying the operation process, thereby reducing the difficulty of operation and improving automation.

[0041] The detection device also includes a movable block 504, a sealing post 505, an elastic telescopic block 506, a tension spring 507, and a cover plate 508. The movable block 504 is slidably mounted on the side of the fixed block 501 away from the frame 1. The sealing post 505 is slidably mounted on the end of the movable block 504 away from the slider 502. One end of the tension spring 507 is fixedly mounted on the side of the fixed block 501 away from the frame 1. The cover plate 508 is fixedly mounted on the other end of the tension spring 507. The fixed end of the elastic telescopic block 506 is slidably mounted on the side of the cover plate 508 close to the fixed block 501. When the elastic telescopic block 506 contacts the slider 502, it will cause the slider 502 to move away from the sealing post 505. When the slider 502 moves, it will drive the limiting block 503 to move. When the limiting block 503 moves, it will release the limitation on the movable block 504.

[0042] The free end of the elastic telescopic block 506 contacts the slider 502, the free end of the elastic telescopic block 506 contacts the sealing post 505, the limiting block 503 contacts the moving block 504, and a through hole is provided in the middle part of the cover plate 508. When the limiting of the moving block 504 is released, the moving block 504 will move to the middle. When the moving block 504 moves to the middle, it will release the limiting of the sealing post 505. At the same time, when the limiting of the sealing post 505 is released, the elastic telescopic block 506 will push the sealing post 505.

[0043] The filling device includes a connecting plate 601, a rotating plate 602, a driving plate 603, a limiting plate 604, a circular plate 605, a retaining ring 606, and a retaining block 607. One end of the connecting plate 601 is fixedly installed on the fixed end of the elastic telescopic block 506. The rotating plate 602 is rotatably installed on the other end of the connecting plate 601. The driving plate 603 is slidably installed inside the through hole of the cover plate 508. The limiting plate 604 is rotatably installed on the side of the driving plate 603 away from the fixed block 501. The circular plate 605 is slidably installed on the side of the cover plate 508 away from the frame 1. The retaining ring 606 is fixedly installed on the side of the cover plate 508 away from the connecting plate 601. The retaining block 607 is slidably installed on the side of the handle 2 away from the frame 1. By pulling the retaining block 607 to limit the retaining ring 606, the position of the relevant components can be fixed, preventing the components from shifting during the replenishment of repair fluid. Then, pushing the sealing column 505 completes the filling. The whole process is continuous and stable, significantly improving the speed of replenishing repair fluid.

[0044] The limiting plate 604 contacts the circular plate 605, and the retaining ring 606 contacts the retaining block 607. When the driving plate 603 moves downward, it will drive the limiting plate 604 downward. When the limiting plate 604 moves downward, it will release the limiting of the circular plate 605. When the limiting of the circular plate 605 is released, the worker can pull the circular plate 605 open.

[0045] In this embodiment, when the repair fluid inside the handle 2 is squeezed out, the tension spring 507 on the fixing block 501 will pull the cover plate 508 downward. When there is no repair fluid inside the handle 2, the cover plate 508 will move to one end of the handle 2 near the frame 1. At the same time, when the cover plate 508 moves, it will drive the elastic telescopic block 506 to move. When the elastic telescopic block 506 moves, it will contact the slider 502 on the fixing block 501.

[0046] When the elastic telescopic block 506 contacts the slider 502, it will cause the slider 502 to move away from the sealing post 505. When the slider 502 moves, it will drive the limiting block 503 to move. When the limiting block 503 moves, it will release the limitation on the moving block 504. When the limitation on the moving block 504 is released, the moving block 504 will move towards the center.

[0047] When the moving block 504 moves towards the center, it releases the limit on the sealing post 505. At the same time, when the limit on the sealing post 505 is released, the elastic telescopic block 506 pushes the sealing post 505, providing a warning to the operator. This eliminates the need for the operator to squeeze the handle 2, reducing the difficulty of operation and improving automation.

[0048] When the elastic telescopic block 506 pushes the sealing column 505 to move, the staff will pull the sealing column 505 outward. At this time, the elastic telescopic block 506 will move outward. When the elastic telescopic block 506 moves outward, the staff can pull the elastic telescopic block 506 outward and then lift the elastic telescopic block 506 upward.

[0049] When the elastic telescopic block 506 moves upward, it will drive the cover plate 508 to move. When the elastic telescopic block 506 is pulled out, it will drive the connecting plate 601 to move. When the connecting plate 601 moves, it will drive the rotating plate 602 to move. When the rotating plate 602 moves, it will cause the driving plate 603, which is pushed up by the rotating plate 602, to move downward. When the driving plate 603 moves downward, it will drive the limiting plate 604 to move downward.

[0050] When the limiting plate 604 moves downward, it will release the limiting of the circular plate 605. When the limiting of the circular plate 605 is released, the operator can pull the circular plate 605 open and at the same time pull the locking block 607 to limit the locking ring 606. Then, the sealing column 505 can be pushed into the handle 2 to inject the repair fluid into the handle 2, making the operation faster.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
