[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0024] Refer to Figure 2 , Figure 3 and Figure 4, in an embodiment of the utility model, a line protection device for communication engineering includes a bottom shell 1 and an upper cover 2 covering the top of the bottom shell 1. A plurality of card slots 9 for clamping communication cables are equidistantly and symmetrically arranged on the opposite sides of the bottom shell 1 and the upper cover 2. The bottom shell 1 and the upper cover 2 are detachably connected through two connection components symmetrically arranged inside the bottom shell 1; the connection components include a screw rod 3 threadedly connected to the inside of the bottom shell 1, a movable block 4 rotatably connected to the top of the screw rod 3, two connecting rods 7 symmetrically and rotatably connected to the outside of the movable block 4, four fixing plates 5 equidistantly and symmetrically fixedly connected to the inner wall of the bottom shell 1, two insertion rods 6, and two connecting plates 8 symmetrically and fixedly connected to the inner wall of the upper cover 2 and located on one side of the corresponding insertion rods 6. The bottom of the screw rod 3 extends to the bottom of the bottom shell 1. The two insertion rods 6 are respectively slidably connected to every two adjacent fixing plates 5. One end of each of the two insertion rods 6 is rotatably connected to the end of the adjacent connecting rod 7. The other end of each of the two insertion rods 6 is inserted into the adjacent connecting plate 8;

[0025] Specifically, the communication cable is placed inside the card slot 9 of the bottom shell 1. The upper cover 2 is moved to cover the top of the bottom shell 1. The cooperation with the card slot 9 on the bottom shell 1 can realize the clamping and fixing operation of the communication cable, and complete the installation work of the bottom shell 1, the upper cover 2 and the communication cable. When the rotatable screw rod 3 rotates, the movement of the movable block 4 can be realized. When the movable block 4 moves upward, it drives the bottom end of the connecting rod 7 to move upward, thereby pushing the insertion rod 6 to move horizontally. Through the cooperation and insertion of the horizontally moving insertion rod 6 and the connecting plate 8, the fixed connection operation between the upper cover 2 and the bottom shell 1 can be completed, ensuring the stability of the installation of the bottom shell 1, the upper cover 2 and the communication cable. The operation is convenient, making the disassembly and assembly work of the installation of the bottom shell 1, the upper cover 2 and the communication cable simpler and more efficient, which is beneficial to improving the efficiency of communication cable construction and has strong practicability.

[0026] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, a heat dissipation component is arranged inside the bottom shell 1 and between every two opposite card slots 9. The heat dissipation component includes a support frame 12 fixedly connected to the bottom of the inner wall of the bottom shell 1, a heat conduction plate 13 fixedly connected to the top of the support frame 12, and a plurality of heat dissipation fins 14 equidistantly fixedly connected to the bottom of the heat conduction plate 13. The bottoms of the plurality of heat dissipation fins 14 all extend to the bottom of the bottom shell 1. When the communication cable is protected inside the bottom shell 1, it contacts the upper surface of the heat conduction plate 13. Specifically, the heat conduction plate 13 can absorb and transfer the heat of the communication cable to the heat dissipation fins 14. The heat dissipation fins 14 in contact with the outside air can dissipate the heat to the outside of the bottom shell 1, thereby well dissipating heat and cooling the communication cable, which is beneficial to ensuring the stability of the use of the communication cable.

[0027] Refer to Figure 1 and Figure 3, the connecting component further includes a knob 11 which is fixedly connected to the bottom of the screw rod 3. Rotating the knob 11 can drive the screw rod 3 to rotate to control the movement of the plug rod 6, making the rotation operation of the screw rod 3 simpler and more convenient.

[0028] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a sealing gasket 10 is fixedly connected to the inner wall of each card slot 9. The sealing gasket 10 can seal the connection between the communication cable and the card slot 9 to prevent rainwater and dust from entering the bottom case 1 through the connection, thus protecting the communication cable well.

[0029] Refer to Figure 4 , two pressing blocks 15 are symmetrically and fixedly connected to the top of the inner wall of the upper cover 2 and above the corresponding heat conducting plates 13. When the upper cover 2 covers the upper part of the bottom case 1, the pressing blocks 15 press on the top of the communication cable, which can fix the communication cable well and make the communication cable contact the heat conducting plate 13 more closely, facilitating heat transfer.

[0030] Refer to Figure 1 , Figure 2 and Figure 3 , a groove parallel to the heat sink 14 is formed on the bottom of the bottom case 1 and near one side of the heat sink 14. The setting of the groove can increase the contact area between the heat sink 14 and the air, thus facilitating the heat sink 14 to better dissipate heat to the outside.

[0031] Working principle: The communication cable is placed inside the card slot 9 of the bottom case 1. Move the upper cover 2 to cover the top of the bottom case 1. Cooperating with the card slot 9 on the bottom case 1 can realize the clamping and fixing operation of the communication cable, and complete the installation work of the bottom case 1, the upper cover 2 and the communication cable. When the rotatable screw rod 3 rotates, the movable block 4 can be moved. When the movable block 4 moves upward, it drives the bottom end of the connecting rod 7 to move upward, thereby pushing the plug rod 6 to move horizontally. Through the cooperation and insertion of the horizontally moving plug rod 6 and the connecting plate 8, the fixed connection operation between the upper cover 2 and the bottom case 1 can be completed, ensuring the stability of the installation of the bottom case 1, the upper cover 2 and the communication cable. The operation is convenient, making the disassembly and assembly work of the installation of the bottom case 1, the upper cover 2 and the communication cable simpler and more efficient, facilitating the improvement of the construction efficiency of the communication cable, and having strong practicability.
