Description

Technical Field

[0001] This utility model relates to the technical field of optical cable protection devices, and in particular to a communication optical cable protection device. Background Technology

[0002] With the continuous development of society and the continuous progress of technology, the technology related to optical cable protection devices is also constantly improving. In order to meet the transmission of communication signals, optical cables are needed. Since optical cables are placed outdoors, optical cable protection devices are needed to increase the service life of optical cables. When in use, the optical cable can be placed inside the protection device, which can protect the optical cable.

[0003] Currently, the protective devices used for communication cables require multiple bolts to be turned and fixed after being fitted onto the outside of the communication cable. This process is cumbersome and time-consuming, resulting in low installation efficiency and hindering the use of optical cable protective devices. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology. Currently, the protective devices used for communication cables require multiple bolts to be rotated for fixing after being sleeved on the outside of the communication cable. The operation is cumbersome and time-consuming, and the installation efficiency is low, which is not conducive to the use of optical cable protection devices. Therefore, a communication optical cable protection device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A communication optical cable protection device includes an upper shell and a lower shell. The upper shell has multiple convex grooves, and a convex block is slidably connected in each convex groove. An arc strip is fixedly connected to the convex block. Multiple arc strips are connected by multiple first reinforcing rods. Multiple sets of limiting members are fixedly connected to the lower shell. Each set of limiting members includes two arc plates, and each arc strip is inserted between two corresponding arc plates.

[0007] Multiple arc-shaped plates are slidably connected with arc-shaped rings, and the multiple arc-shaped rings are connected by multiple second reinforcing rods. Each arc-shaped ring is slidably connected with a plug rod, and the lower end of each plug rod is engaged with the corresponding convex block. The multiple plug rods are connected by a horizontal plate, and one of the arc-shaped rings is provided with a rotating component.

[0008] Preferably, the rotating assembly includes a threaded rod that is threadedly connected to the arc-shaped ring, the threaded rod having an L-shaped cross-section, and a rubber pad is fixedly connected to the upper surface of the cross plate.

[0009] Preferably, each of the insert rods is fitted with a first spring, one end of the first spring is fixedly connected to the insert rod, and the other end of the first spring is fixedly connected to the corresponding arc-shaped ring.

[0010] Preferably, the inner walls of the upper outer shell and the lower outer shell are each fixedly connected to two sealing blocks, each sealing block having a sealing cavity, and a sealing strip being slidably connected within the sealing cavity, with a roller installed at one end of the sealing strip.

[0011] Preferably, each of the sealing strips is fitted with a second spring, one end of the second spring being fixedly connected to the sealing strip, and the other end of the second spring being fixedly connected to the inner wall of the sealing cavity.

[0012] Preferably, both the upper and lower outer shells have cavities, and each cavity is slidably connected to an arc-shaped sealing plate. Each arc-shaped sealing plate is connected to a first arc-shaped block and a second arc-shaped block via two sliding rods. Two locking blocks are fixedly connected to the second arc-shaped block. Both ends of the first arc-shaped block have grooves for connecting the locking blocks. A threaded rod is threadedly connected to the upper outer shell. The second arc-shaped block and the threaded rod are rotatably connected. Each cavity communicates with two corresponding sealing cavities.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Place the lower outer shell horizontally, put the communication optical cable in the center of the inner wall of the lower outer shell, cover with the upper outer shell, push the arc strip along the convex groove so that the arc strip is inserted between the corresponding two arc plates, then push the arc ring, the arc ring slides along the arc plate until each plug is directly above the corresponding convex block. Then press the horizontal plate to drive the plug to compress the first spring. After each plug moves, it will lock into the slot of the corresponding convex block, completing the initial locking. Finally, rotate the L-shaped threaded rod until the surface of the threaded rod is in close contact with the rubber pad on the horizontal plate, effectively preventing the horizontal plate from moving back, and thus effectively preventing the plug from disengaging from the slot. The upper and lower outer shells can be firmly connected together. The operation is relatively simple and time-saving, and the installation efficiency is high, which is beneficial to the use of optical cable protection devices. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-5 A communication optical cable protection device includes an upper outer shell 2 and a lower outer shell 1. The upper outer shell 2 and the lower outer shell 1 are injection molded from high-strength, corrosion-resistant engineering plastic ABS+PC alloy. The inner diameter is designed to be adapted to the diameter of the optical cable, and the wall thickness is controlled at 3-5mm to balance strength and lightness. The upper outer shell 2 has multiple convex grooves 4, and a convex block 19 is slidably connected in each convex groove 4. An arc-shaped strip 14 is fixedly connected to the convex block 19, and the multiple arc-shaped strips 14 are connected by multiple first reinforcing rods 18. Multiple sets of limiting components are fixedly connected to the lower outer shell 1. Each set of limiting components includes two arc-shaped plates 7. Each arc-shaped strip 14 is inserted between two corresponding arc-shaped plates 7. Arc-shaped rings 6 are slidably connected to multiple arc-shaped plates 7. Multiple arc-shaped rings 6 are connected by multiple second reinforcing rods 3. Each arc-shaped ring 6 is slidably connected to an insert rod 20. The lower end of each insert rod 20 is engaged with a corresponding convex block 19. Multiple insert rods 20 are connected by a horizontal plate 5. A rotating component is provided on one of the arc-shaped rings 6.

[0024] refer to Figure 4The rotating assembly includes a threaded rod 21 that is threadedly connected to the arc-shaped ring 6. The threaded rod 21 has an L-shaped cross-section. A rubber pad is fixedly connected to the upper surface of the horizontal plate 5. Each insert rod 20 is fitted with a first spring. One end of the first spring is fixedly connected to the insert rod 20, and the other end of the first spring is fixedly connected to the corresponding arc-shaped ring 6. After each insert rod 20 is positioned directly above the corresponding convex block 19, the horizontal plate 5 is pressed to compress the first spring by moving the insert rod 20. After each insert rod 20 moves, it will engage with the corresponding convex block 19's groove. The groove depth is 2-4mm, completing the initial locking. Finally, the L-shaped threaded rod 21 is rotated to screw it into the threaded hole on the arc-shaped ring 6 until the surface of the threaded rod 21 is tightly attached to the rubber pad on the horizontal plate 5, effectively preventing the horizontal plate 5 from shifting back.

[0025] refer to Figure 2 and Figure 5 The inner walls of both the upper outer shell 2 and the lower outer shell 1 are fixedly connected to two sealing blocks 13. Each sealing block 13 has a sealing cavity, and a sealing strip 15 is slidably connected within the sealing cavity. A roller 16 is installed at one end of the sealing strip 15. A second spring 17 is fitted onto each sealing strip 15. One end of the second spring 17 is fixedly connected to the sealing strip 15, and the other end of the second spring 17 is fixedly connected to the inner wall of the sealing cavity. Both the upper outer shell 2 and the lower outer shell 1 have cavities. An arc-shaped sealing plate 22 is slidably connected within each cavity. Each arc-shaped sealing plate 22 is connected to a first arc-shaped block 8 and a second arc-shaped block 10 via two sliding rods 12. Two locking blocks 9 are fixedly connected to the second arc-shaped block 10. Grooves for connecting the locking blocks 9 are provided at both ends of the first arc-shaped block 8. A fixing rod 11 is threaded onto the shell 2. The second arc-shaped block 10 is rotatably connected to the fixing rod 11. Each cavity is connected to two corresponding sealing cavities. The sealing strip 15 has good sealing performance when connected to the inner wall of the sealing cavity. After each locking block 9 is inserted into the corresponding groove, the fixing rod 11 of the upper shell 2 is rotated, driving the second arc-shaped block 10 to slide along the cavity. Each sliding rod 12 slides relative to the upper shell 2 and the lower shell 1 respectively. The sliding rod 12 drives the arc-shaped sealing plate 22 to move radially and compresses the air in the cavity. The air is pressed into the sealing cavity of the sealing block 13 through the connecting hole on the sealing block 13, pushing the sealing strip 15 out. After each roller 16 moves, it will be in close contact with each side surface of the communication cable. By using the roller 16 to contact the surface of the optical cable, the communication cable can be supported.

[0026] In this invention, the lower outer shell 1 is placed horizontally, and the communication optical cable is placed in the center of the inner wall of the lower outer shell 1. The upper outer shell 2 is then placed on top. At this time, each arc-shaped strip 14 is located between every two arc-shaped plates 7 of the lower outer shell 1, and each locking block 9 is engaged in the corresponding groove. The arc-shaped strip 14 is pushed along the convex groove 4 of the upper outer shell 2, so that the arc-shaped strip 14 is inserted between the corresponding two arc-shaped plates 7 of the lower outer shell 1. Multiple first reinforcing rods 18 are fixedly connected to multiple arc-shaped strips 14 to ensure that the upper outer shell 2 is subjected to uniform force and can drive multiple arc-shaped strips 14 to move simultaneously. Then, the arc-shaped ring 6 is pushed, and the arc-shaped ring 6 slides along the arc-shaped plate 7. Since each second reinforcing rod 3 is fixedly connected to multiple arc-shaped rings 6, Multiple arc-shaped rings 6 move synchronously until each insertion rod 20 is directly above the corresponding convex block 19. Then, pressing the horizontal plate 5 causes the insertion rod 20 to compress the first spring. After each insertion rod 20 moves, it will engage with the corresponding convex block 19's slot. The slot depth is 2-4mm, completing the initial locking. Finally, rotate the L-shaped threaded rod 21 to screw it into the threaded hole of the arc-shaped ring 6 until the surface of the threaded rod 21 is in close contact with the rubber pad on the horizontal plate 5, effectively preventing the horizontal plate 5 from moving back, and thus effectively preventing the insertion rod 20 from disengaging from the slot. This can firmly connect the upper outer shell 2 and the lower outer shell 1 together. The operation is relatively simple and time-saving, and the installation efficiency is high, which is beneficial to the use of optical cable protection devices.
