In existing technologies, communication lines often become tangled and disorganized, posing safety hazards and potentially affecting the normal operation of surrounding power lines.

[0003] Patent application number 2020112112094 discloses a line protection device for communication engineering, including a U-shaped frame. A mounting hole is provided in the center of the top of the U-shaped frame, and a support shaft is slidably and rotatably mounted on the mounting hole. A hand-cranked lifting component is mounted on the upper end of the support shaft, and an adjusting crossbar is fixedly mounted on the lower end of the support shaft.

This device facilitates the orderly winding of excess communication lines and provides reliable protection for communication lines, making it worthy of widespread application.

[0004] However, in practical applications, due to the thermal expansion and contraction of cables, excessive tension in the cables can easily lead to cable failure, and in extreme cases, wire breakage may occur. The device requires manual adjustment when the cable is subjected to excessive tension, which needs to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a communication line protection device.

[0006] To solve the above problems, the technical solution of this utility model is as follows: a communication line protection device, including a housing and a bottom cover, the housing has wire holes at both ends, a winding disc is installed inside, a rotating shaft is installed through and rotatably on the top surface of the housing, the winding disc is installed on the rotating shaft, a locking mechanism is provided on the outside of the rotating shaft, a handwheel is installed on the top, and a buffer mechanism is provided on both sides of the winding disc inside the housing.

[0007] The locking mechanism includes a gear mounted on a rotating shaft and a movable plate rotatably mounted on the top surface of the housing. The top surface of the housing has an arc-shaped sliding groove. A positioning block is fixed to one side of the movable plate, and a paddle is fixed to the top of the other end.

[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the communication line protection device includes a housing 1 and a bottom cover 2. The housing 1 has wire holes at both ends and a winding disc 3 is installed inside. Positioning posts 12 are fixed at the four corners inside the housing 1. The bottom cover 2 is installed on the positioning posts 12 by screws. A rotating shaft 4 is installed through and rotatably on the top surface of the housing 1. The winding disc 3 is installed on the rotating shaft 4, and a locking mechanism is provided on the outside of the rotating shaft 4. Buffer mechanisms are provided on both sides of the winding disc 3 inside the housing 1.

[0023] The middle part of the cable is wound on the winding reel 3, and the two ends pass through the guide wheels 11 of the two buffer mechanisms and then pass through the wire hole. When winding the winding reel 3, the middle part of the cable is first fixed in the middle part of the winding reel 3, and then the two ends of the cable are wound, so that when the winding reel 3 is rotated, the cables on both sides can be wound or unwound synchronously.

[0024] The locking mechanism includes a gear 5 mounted on a rotating shaft 4 and a movable plate 6 rotatably mounted on the top surface of the housing 1. The top surface of the housing 1 has an arc-shaped groove. A positioning block 7 is fixedly connected to one side of the movable plate 6, and a lever 8 is fixedly connected to the top of the other end. The positioning block 7 has teeth that mesh with the gear 5. The lever 8 extends through the groove to the top of the housing 1. An ear plate 13 is fixedly connected to the end of the movable plate 6 away from the positioning block 7. A fixing plate 14 is installed on one side of the ear plate 13 at the top of the housing 1. A spring 15 connects the fixing plate 14 and the ear plate 13. One end of the movable plate 6 extends between two telescopic rods 9, and a vertical rod 16 is fixedly connected to the top of a fixing frame 10 near the winding reel 3.

[0025] The buffer mechanism includes two staggered telescopic rods 9. A fixed frame 10 is installed at the end of each telescopic rod 9. A guide wheel 11 is installed inside the fixed frame 10. Limiting plates 17 are fixedly connected to both sides of the winding reel 3 inside the housing 1. The limiting plates 17 have through holes, and the through holes on the two limiting plates 17 are respectively located on both sides of the winding reel 3. Each telescopic rod 9 includes a fixed cylinder 9.1. A movable block 9.2 is slidably provided inside the fixed cylinder 9.1. A spring 9.3 is provided on one side of the movable block 9.2, and a movable rod 9.4 is fixedly connected to the other side, passing through the end face of the fixed cylinder 9.1. The fixed frame 10 is installed at the end of the movable rod 9.4. Two protrusions are symmetrically fixed to the side of the movable block 9.2. A groove adapted to the protrusions is provided on the inner wall of the fixed cylinder 9.1.

[0026] In practical use, when the cable tension is high, the guide wheel 11 will squeeze the telescopic rod 9 through the fixed frame 10, causing the telescopic rod 9 to retract. At the same time, the fixed frame 10 will drive the vertical rod 16 to move, releasing part of the cable and reducing the tension. When the tension is still too high, the fixed frame 10 will drive the vertical rod 16 to continue moving. The vertical rod 16 will exert a pushing force on the movable plate 6, causing the movable plate 6 to rotate. The spring 15 will stretch, further separating the positioning block 7 from the gear 5. The tension will cause the winding disc 3 to rotate and further release the cable. When the tension decreases, the pushing force of the vertical rod 16 on the movable plate 6 will gradually decrease. Under the action of the spring 15, the teeth of the positioning block 7 will re-mesh with the gear 5, thus fixing the winding disc 3.

[0027] When it is necessary to tighten the cable, push the movable plate 6 to rotate by the lever 8, so that the positioning block 7 separates from the gear 5. At this time, rotate the winding reel 3 by the handwheel to wind the cable. After winding is completed, release the lever 8.
