Abstract
Description
Technical Field
[0001] This utility model relates to the field of power engineering technology, and in particular to a stainless steel alloy round wire connection structure for grounding wires. Background Technology
[0002] In fields such as power systems, electrical equipment installation and maintenance, grounding is a fundamental element for ensuring personal safety and the normal operation of equipment. As a key component connecting equipment or facilities to the grounding electrode, the reliability of the grounding wire connection directly affects the effectiveness of the entire grounding system. Traditional grounding wire connection methods, such as bolt fastening or simple winding connections, have revealed numerous problems in practical applications.
[0003] Grounding wires are subjected to various external forces during operation, including their own weight, wind force, and tensile force (such as when equipment is moved or vibrates). Traditional connection structures often lack effective anti-loosening and limiting measures. When the grounding wire is pulled, the connection is prone to loosening, misalignment, or even complete detachment, leading to grounding failure. This is especially dangerous on high-voltage or critical equipment. At the same time, if the connection structure is not properly designed, excessive compression of the internal conductors can occur when tightening or under pressure, damaging the conductor insulation layer or the conductor itself, affecting its conductivity and lifespan.
[0004] To address the above issues, a stainless steel alloy round wire connection structure for grounding wires needs to be designed to overcome these problems. Utility Model Content
[0005] The main objective of this invention is to provide a stainless steel alloy round wire connection structure for grounding wires, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stainless steel alloy round wire connection structure for grounding wire includes a sleeve, a sealing flange, a grounding wire, and a rubber tooth block, wherein one end of the sleeve is provided with an anti-torque mounting component; The anti-torque installation assembly includes connecting rods at one end of the sleeve, two connecting rods connected to a U-shaped limiting frame at the ends away from the sleeve, a slot being formed at the bottom of the inner side of the U-shaped limiting frame, a protective frame connected to one end of the U-shaped limiting frame, rounded corner limiting sleeves connected to both ends of the protective frame away from the U-shaped limiting frame, an adjusting block connected to the bottom of the inner side of the protective frame, a movable rod connected to the end of the adjusting block away from the protective frame passing through the end of the U-shaped limiting frame, a limiting plate sleeved on the outer wall of the two movable rods near the protective frame, a pressure wheel connected to the end of the two movable rods away from the limiting plate, a limiting spring connected to the top of the two movable rods, a support rod connected to the top of the limiting spring passing through the top of the U-shaped limiting frame, and elastic pads on the top of the support rod.
[0007] As a preferred embodiment of this utility model, one end of the support rod is connected to a reinforcing rod, the end of the reinforcing rod away from the support rod is connected to a limiting block, the bottom of the limiting block is connected to a buffer spring, and the bottom of the buffer spring is fixedly connected to the top of the adjusting block.
[0008] In a preferred embodiment of this utility model, the sleeve is rotatably connected to the U-shaped limiting frame via two connecting rods, and the U-shaped limiting frame is threadedly fixed to the protective frame via two rounded corner limiting sleeves.
[0009] As a preferred embodiment of this utility model, the two movable rods pass through both ends of the U-shaped limiting frame and are rotatably connected to the two adjusting blocks, and the two adjusting blocks are rotatably connected to the inner side of the protective frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This stainless steel alloy round wire connection structure for grounding wires connects two sleeves via a sealing flange. Rubber teeth prevent squeezing when the round wire connects to the grounding wire. A connecting rod connects the sleeve to a U-shaped limiting frame. A slot on the bottom inner side of the U-shaped limiting frame limits the grounding wire. A pressure roller contacts one end of the grounding wire, limiting it within the slot and preventing torque deviation. When the grounding wire is pulled, the limiting springs at the top of the two movable rods are impacted by the upward force of the pressure roller, causing the elastic pads to contact the bottom inner side of the protective frame, thus limiting the U-shaped limiting frame and the pressure roller. A reinforcing rod connects to a limiting block; when the limiting spring moves, it moves the buffer spring at the bottom of the limiting block within the protective frame, ensuring stability of the support rod. Simultaneously, an adjusting block moves within the protective frame following the movement of the buffer spring and movable rods, also providing a limiting effect. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figures 1-5 As shown, a stainless steel alloy round wire connection structure for grounding wire includes a sleeve 1, a sealing flange 2, a grounding wire 3, and a rubber tooth block 5. One end of the sleeve 1 is provided with an anti-torque mounting component 4. The anti-torque installation assembly 4 includes connecting rods 401 at one end of the sleeve 1. A U-shaped limiting frame 402 is connected to the end of each connecting rod 401 away from the sleeve 1. A slot 403 is provided at the bottom of the inner side of the U-shaped limiting frame 402. A protective frame 408 is connected to one end of the U-shaped limiting frame 402. Rounded corner limiting sleeves 415 are connected to both ends of the protective frame 408 away from the U-shaped limiting frame 402. An adjusting block 411 is connected to the bottom of the inner side of the protective frame 408. The adjusting block 411 is located away from the anti-torque installation assembly 4. One end of the protective frame 408 passes through the other end of the U-shaped limiting frame 402 and is connected to a movable rod 413. The outer walls of the two movable rods 413 are sleeved with a limiting plate 412 at the end near the protective frame 408. The ends of the two movable rods 413 away from the limiting plate 412 are connected to a pressure wheel 414. The top of the two movable rods 413 is connected to a limiting spring 404. The limiting spring 404 passes through the top of the U-shaped limiting frame 402 and is connected to a support rod 405. The top of the support rod 405 has two elastic pads 406. One end of the support rod 405 is connected to a reinforcing rod 407. The end of the reinforcing rod 407 away from the support rod 405 is connected to a limiting block 409. The bottom of the limiting block 409 is connected to a buffer spring 410. The bottom of the buffer spring 410 is fixedly connected to the top of the adjusting block 411. Sleeve 1 is rotatably connected to U-shaped limiting frame 402 via two connecting rods 401. U-shaped limiting frame 402 is threadedly fixed to protective frame 408 via two rounded corner limiting sleeves 415. Two movable rods 413 pass through both ends of U-shaped limiting frame 402 and are rotatably connected to two adjusting blocks 411. The two adjusting blocks 411 are rotatably connected to the inner side of protective frame 408. Two limiting discs 412 are sleeved on the outer wall of the two movable rods 413 near the end of the adjusting blocks 411. The two movable rods 413 are rotatably connected to pressure rollers 414. The two movable rods 413 are fixed to two limiting springs 404. The limiting springs 404 are fixedly connected to support rods 405. The top of elastic pad 406 contacts the top of the inner side of protective frame 408. Reinforcing rod 407 is fixedly connected to limiting block 409. Limiting block 409 is fixedly connected to buffer spring 410. The outer wall of limiting block 409 contacts the inner side of protective frame 408. The connecting wire 3 is placed inside the U-shaped limiting frame 402, with its bottom locked in the slot 403. At this time, the pressure roller 414 has not yet fully pressed the connecting wire 3. When the connecting wire 3 contacts the round wire and needs to be stably connected, the connecting wire 3 will push the pressure wheel 414 to move upward. The pressure wheel 414 drives the movable rod 413 to move upward. The movement of the movable rod 413 drives the adjusting block 411 to move upward through the rotation connection. The movement of the adjusting block 411 compresses the buffer spring 410 at its top. The compression of the buffer spring 410 causes the limiting block 409 to move downward in the guide groove on the inner side of the protective frame 408. The movement of the limiting block 409 drives the support rod 405 to move through the reinforcing rod 407, so that the elastic pad 406 contacts the top of the inner side of the protective frame 408, which plays a supporting and limiting role, preventing the pressure wheel 414 from moving upward too much. At the same time, the upward movement of the movable rod 413 is limited by the limiting plate 412 and provides a certain reverse force through the limiting spring 404, further stabilizing the position of the pressure wheel 414. Finally, the pressure wheel 414 reliably presses the connecting wire 3 into the slot 403, preventing it from deviating under the action of torque. When the connecting wire 3 is subjected to an outward pulling force, the force is transmitted to the pressure roller 414, causing it to tend to move outward. The pressure roller 414 drives the movable rod 413 to move outward, and the movement of the movable rod 413 also drives the adjusting block 411 to move, compressing the buffer spring 410, causing the limiting block 409 to move within the protective frame 408, and stabilizing the support rod 405 through the reinforcing rod 407. More importantly, the movement of the movable rod 413 will compress the limiting spring 404 at its top. When the pulling force is large enough, the upward impact force of the pressure roller 414 or the movement of the movable rod will be transmitted through the limiting spring 404, causing the support rod 405 to drive the elastic pad 406 to contact and deform with the top of the inner side of the protective frame 408, absorbing part of the impact energy, so that the entire system is protected from impact. When pulled, the impact can be buffered by the deformation of the buffer spring 410, the limit spring 404, and the elastic pad 406, protecting the connection structure from damage, while still maintaining the limit of the connecting wire 3. During the change of pulling force or installation adjustment, the movement of the movable rod 413 drives the adjusting block 411 to move on the inner side of the protective frame 408, which plays a dynamic limiting role and prevents the movable rod 413 from moving excessively. The limit block 409 moves with the buffer spring 410 on the inner side of the protective frame 408, and its outer wall contacts the inner side of the protective frame 408, increasing the friction and improving the stability of the support rod 405, thereby ensuring the stable operation of the entire anti-torque limiting assembly. The limit plate 412 ensures that the movable rod 413 and the pressure wheel 414 work within the safe stroke.
[0018] It should be noted that this utility model is a stainless steel alloy round wire connection structure for grounding wires. In use, firstly, one end of the stainless steel alloy round wire is connected to the sleeve 1. The two sleeves 1 are sealed and connected by the sealing flange 2. The stainless steel alloy round wire and the connecting wire 3 can contact the rubber tooth block 5 on the inner side of the sleeve 1. Connect the connecting wire 3 to the round wire that has been connected. During the connection process, the toothed structure of the rubber tooth block 5 can disperse and buffer the local pressure on the connecting wire 3 or the round wire during the tightening or connection process, prevent damage to the wire due to excessive squeezing, and ensure the physical integrity of the connection. After the connecting wire 3 is connected, it is guided into the U-shaped limiting frame 402. The slot 403 at the bottom of the inner side of the U-shaped limiting frame 402 provides initial guidance and limitation for the entering connecting wire 3, confining it within a specific path. The pressure roller 414, located inside the U-shaped limiting frame 402 at the end of the connecting wire 3's path, contacts one end of the connecting wire 3. When the connecting wire 3 fully enters and contacts the pressure roller 414, the pressure roller 414 applies a downward pressure to the connecting wire 3, pressing it into and limiting it within the slot 403. This effectively prevents the connecting wire 3 from lateral displacement within the inner side of the U-shaped limiting frame 402. When the entire grounding system is subjected to external tensile forces such as wind, equipment vibration, or accidental pulling, the force will move along... The connecting wire 3 transmits the force to the pressure roller 414. The pressure roller 414 is pulled upward by the connecting wire 3. This force is transmitted to the two movable rods 413 connected to it through the pressure roller 414. The movement of the movable rod 413 will compress the limiting spring 404 located at its top. After the limiting spring 404 is compressed, its upper end will hit and push the support rod 405. The top of the support rod 405 is connected to the elastic pad 406. When the support rod 405 moves, the elastic pad 406 will contact the bottom of the inner side of the protective frame 408, thereby limiting the U-shaped limiting frame 402 and the pressure roller 414 and preventing the pressure roller from moving too high and detaching under extreme tension. At the same time, the movable rod 413 moves in the groove on the inner side of the U-shaped limiting frame 402. The movement of the movable rod 413 causes the adjusting block 411 at the other end to move upward. When the adjusting block 411 moves upward, it applies pressure to the buffer spring 410 below it, compressing the buffer spring 410. The buffer spring 410 is located at the bottom of the limiting block 409. Its compression plays a buffering role, absorbing part of the impact energy brought by the pulling force and protecting the connection structure from severe impact damage. When the limiting block 409 moves as the buffer spring 410 is compressed, the reinforcing rod 407 also moves accordingly. The reinforcing rod 407 improves the stability of the movement of the limiting block 409 and provides additional support for the structure of the support rod 405, ensuring that the elastic pad 406 can stably contact the protective frame 408. The outer wall of the limiting block 409 contacts the inner side of the protective frame 408. As the buffer spring 410 is compressed and rebounds, the limiting block 409 slides on the inner side of the protective frame 408, enhancing the guiding nature of the limiting block 409 and further improving the connection stability between the U-shaped limiting frame 402 and the protective frame 408.
