Description

Technical Field

[0001] This utility model relates to the field of cable lightning protection and grounding technology, and specifically to a coaxial cable lightning protection and grounding device. Background Technology

[0002] In fields such as communications, broadcasting, and industrial control, coaxial cables serve as crucial signal transmission carriers, and their lightning protection grounding performance directly impacts the system's stability and safety. Lightning protection grounding devices effectively protect cables and downstream equipment from surge impacts by channeling induced lightning currents to the earth.

[0003] Traditional grounding devices often use welding, bolting and other methods to connect the grounding electrode and the cable. This requires professional tools such as welding machines and wrenches. The welding process is easily restricted by the environment and requires a lot of time to crimp and weld the grounding electrode, which makes the installation of a single device too time-consuming and affects the efficiency of the project.

[0004] To address the aforementioned issues, this application proposes a coaxial cable lightning protection grounding device. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a coaxial cable lightning protection grounding device.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a coaxial cable lightning protection grounding device, including a ground and a tower body, and also including a connecting component. The connecting component includes a base fixedly connected to the ground and the tower body, a connecting column fixedly connected to the top of the base, and an external threaded column connected to the internal thread of the connecting column.

[0007] The engaging assembly includes an internally threaded post threadedly connected to an externally threaded post. The four corners of the bottom end of the internally threaded post are provided with a sliding groove. A push rod is slidably connected to the sliding groove. A positioning ring is fixedly connected to the bottom end of the externally threaded post. A rotating shaft is rotatably connected to each of the four corners inside the positioning ring. A locking block is rotatably connected to the outside of the rotating shaft.

[0008] Preferably, the inner side of the card block is provided with a second sliding groove, and the outer side of the push rod is movably connected to the second sliding groove.

[0009] Preferably, the end of the card block away from the slide groove has a card slot, which engages with the interior of the base.

[0010] Preferably, a connecting line is sleeved on the outer side of the external threaded post, and the bottom end of the connecting line contacts the top end of the connecting post.

[0011] Preferably, the outer thread of the external threaded post is connected with a bolt.

[0012] Preferably, the top end of the connecting wire contacts the bottom end of the bolt and touches the ground.

[0013] Preferably, the outer bottom end of the internally threaded column is slidably connected to the inside of the positioning ring.

[0014] The beneficial effects of this utility model are:

[0015] 1. By rotating the external threaded column, its external thread engages with the internal thread of the connecting column, causing the external threaded column to move axially and press the connecting line. Then, the bolt is tightened, and the connecting line is further pressure-connected through the thread pressure, forming a multi-layer conductive contact surface. This design only requires rotating the external threaded column and the bolt to complete the crimping, without the need for welding or special tools, effectively solving the problem of increased time consumption caused by the traditional partial connection requiring welding installation.

[0016] 2. By rotating the internal threaded column, it moves along the axial direction of the internal thread of the external threaded column, pushing the push rod in the first slide groove downward. The end of the push rod slides in the second slide groove of the locking block, driving the locking block to rotate around the axis, and finally making the locking groove and the inside of the base rigidly engaged. This design only requires rotating the internal threaded column to complete locking and unlocking. By forming a multi-point engagement between the locking block and the base, the vibration resistance and loosening ability are improved, solving the problem of repeated calibration and alignment required for traditional bolt tightening.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0030] Reference Figure 1-5 A coaxial cable lightning protection grounding device includes a ground surface 1 and a tower body 2, and a connecting assembly 3. The connecting assembly 3 includes a base 31 fixedly connected to the ground surface 1 and the tower body 2. A connecting post 32 is fixedly connected to the top of the base 31. An externally threaded post 33 is connected to the internal thread of the connecting post 32. A connecting wire 5 is sleeved on the ground surface 1 outside the externally threaded post 33. The bottom end of the connecting wire 5 contacts the top of the connecting post 32. A bolt 34 is connected to the externally threaded post 33. The top end of the connecting wire 5 contacts the bottom end of the bolt 34, which in turn contacts the ground surface 1.

[0031] Ground 1 serves as the foundational support platform for the entire device, bearing the weight of tower 2 and related components, and providing the final conductive path for grounding, enabling lightning to be safely conducted to the earth for effective grounding. Tower 2, as a support and connection structure, supports equipment such as coaxial cables and, in conjunction with connection component 3, guides lightning to the grounding system, playing a crucial role in lightning conduction. Base 31 is fixedly connected to ground 1 and tower 2, providing a stable installation foundation for the entire connection component 3, ensuring stable connection and installation of connecting column 32 and other subsequent components, while also serving as an initial grounding transition. One end of connecting column 32 is fixedly connected to base 31, while the other end provides a connection platform for subsequent components such as externally threaded column 33. The internal threaded structure connects with the externally threaded column. The connection is adjusted by the threaded post 33 to connect the coaxial cable and the grounding system. The threaded post 33 is connected to the connecting post 32 by threads on its outer side and is also connected to the connecting line 5 to connect the outer conductor of the coaxial cable to the grounding system. This plays a key role in conducting lightning and ensures that lightning can be successfully conducted to the ground 1 through the connecting line 5. The bolt 34 is threaded to the outer side of the threaded post 33 to tighten the connecting line 5 and ensure a tight contact between the connecting line 5 and the threaded post 33. This prevents the connecting line 5 from loosening or falling off and ensures the continuity of lightning conduction. One end of the connecting line 5 is connected to the top of the connecting post 32, and the other end is connected to the threaded post 33 by the bolt 34. As a conductor for lightning conduction, it guides the lightning voltage in the coaxial cable to the ground 1, achieving effective lightning protection grounding.

[0032] Reference Figure 3-5 The engaging component 4 includes an internally threaded post 41 threadedly connected to the internally threaded post 33. The bottom corners of the internally threaded post 41 have four sliding grooves 42, on which a push rod 43 is slidably connected. A positioning ring 44 is fixedly connected to the bottom of the externally threaded post 33. The outer bottom end of the internally threaded post 41 is slidably connected to the inside of the positioning ring 44. A rotating shaft 45 is rotatably connected to each of the four corners inside the positioning ring 44. A locking block 47 is rotatably connected to the outer side of the rotating shaft 45. A second sliding groove 46 is formed on the inner side of the locking block 47, and the outer side of the push rod 43 is movably connected to the second sliding groove 46. A locking slot 48 is formed at the end of the locking block 47 away from the second sliding groove 46, and the locking slot 48 engages with the interior of the base 31.

[0033] The internal threaded post 41 is threadedly connected to the external threaded post 33. This connection serves two purposes: firstly, it connects and fixes the push rod 43; secondly, through its outer bottom end sliding connection with the positioning ring 44, it engages with the base 31 in conjunction with the locking block 47 and other structures. A first sliding groove 42 is located at the four corners of the bottom end of the internal threaded post 41, providing a sliding track for the push rod 43. This allows the push rod 43 to slide along the first sliding groove 42, thereby driving the locking block 47 to move. One end of the push rod 43 slides on the first sliding groove 42, while the other end is movably connected to the second sliding groove 46 of the locking block 47. The sliding of the push rod 43 pushes or pulls the locking block 47 to rotate around the rotating shaft 45, thereby engaging or disengaging the locking groove 48 of the locking block 47 from the interior of the base 31. The positioning ring 44 is fixedly connected to the bottom end of the external threaded post 33, providing sliding support for the outer bottom end of the internal threaded post 41. Simultaneously, it has a rotating shaft 45 and a locking block 47 rotatably connected internally, serving to engage or disengage the locking block. The positioning and supporting function of 47 ensures that the locking block 47 can rotate stably around the rotating shaft 45. The rotating shaft 45 is rotatably connected to the four corners inside the positioning ring 44, and is used to connect and support the locking block 47, so that the locking block 47 can rotate around the rotating shaft 45, thereby realizing the locking and disengaging action of the locking block 47. The second slide groove 46 is opened on the inner side of the locking block 47, and is used to movably connect the push rod 43, so that the push rod 43 can move in the second slide groove 46, thereby converting the sliding of the push rod 43 into the rotation of the locking block 47. The locking block 47 is rotatably connected to the inside of the positioning ring 44 through the rotating shaft 45. The end away from the second slide groove 46 has a locking groove 48, which is used to engage with the inside of the base 31, thereby realizing the fixed connection between the external threaded column 33 and the base 31. The locking groove 48 is opened at the end of the locking block 47 away from the second slide groove 46, and engages with the inside of the base 31, which plays the role of fixing the connection between the external threaded column 33 and the base 31.

[0034] Working principle:

[0035] First, rotate the external threaded post 33. Its external thread engages with the internal thread of the connecting post 32, which in turn generates axial pressure on the contact surface between the top of the external threaded post 33 and the connecting line 5. At this time, tighten the bolt 34 on the outside of the external threaded post 33 to connect the connecting line 5, thereby forming a multi-layer conductive contact surface between the coaxial cable outer conductor, the connecting line 5 and the grounding system. Then, rotate the internal threaded post 41. The threaded structure moves along the inside of the external threaded post 33, which in turn drives the slide groove 42 at the bottom of the internal threaded post 41 to push the push rod 43 downward. The end of the push rod 43 moves laterally in the slide groove 46 of the locking block 47, which drives the locking block 47 to rotate around the rotating shaft 45 on the positioning ring 44. This causes the outer groove 48 to mechanically engage with the inside of the base 31, achieving rigid locking between the external threaded post 33 and the base 31, ensuring the structural stability of the lightning conduction path.
