Description

Technical Field

[0001] The present application belongs to the technical field of cable installation, and specifically relates to an electric power fitting. Background Art

[0002] In the power transmission system, the fixing and support of cables is the key link to ensure the safe and stable transmission of electricity. With the continuous growth of power demand and the increasing complexity of the power grid architecture, the number and density of cables are increasing continuously.

[0003] Traditional power fittings are designed to fix a single cable. This single cable fixing mode has exposed many limitations when facing today's complex power engineering needs. For example, in underground pipe corridors of urban power grids, inside substations, and on towers of high-voltage transmission lines, it is often necessary to lay and fix multiple cables at the same time to meet the requirements of different voltage levels and power distribution. However, due to the single structure and function of the fittings in the prior art, only one cable can be fixed at a time. This means that in the scenario of laying multiple cables, construction workers need to spend a lot of time and energy to install and adjust the fittings one by one, which greatly reduces construction efficiency and increases the construction period and labor costs.

[0004] In addition, from the perspective of space utilization and the rationality of line layout, if multiple cables are fixed in the traditional single-cable manner, it will not only take up too much space, resulting in a messy line layout, which is not conducive to subsequent maintenance and inspection work, but may also cause friction and collision between cables due to the unstable relative position between the cables, thereby affecting the insulation performance and service life of the cables, and bringing potential risks to the safe and stable operation of the power system.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0022] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0023] See also Figures 1 to 5 As shown, according to an embodiment of the present application, an electrical hardware is provided, including: a base 1, a movable groove 11 is provided on the outer peripheral surface of the base 1, and a movable ring 2 that can rotate with the axis of the base 1 as the rotation center is arranged in the movable groove 11; a bracket 3, the bracket 3 is arranged on the outer wall of the movable ring 2 and extends along the radial direction of the base 1, a mounting groove 31 is provided on the bracket 3, and a plurality of positioning holes 32 are equidistantly provided at the bottom of the mounting groove 31, a plurality of slides 4 are slidably sleeved on the bracket 3, and a fixed block 5 is movably provided on the slide 4 in a direction perpendicular to the mounting groove 31, and the fixed block 5 includes a first end for inserting into the positioning hole 32 and a second end for connecting and clamping a positioning clamp 6 for clamping the cable to be fixed.

[0024] In this embodiment, by arranging a plurality of sliding sleeves on the bracket 3, and the fixed block 5 on the slide 4 can move perpendicular to the direction of the installation groove 31, the number and position of the slide 4 can be freely adjusted according to the actual number and distribution of cables, thereby meeting the requirement of fixing multiple cables at the same time. Further, the first end of the fixed block 5 can be inserted into the positioning hole 32 at different positions of the bottom of the installation groove 31, thereby the fixed position of the fixed block 5 can be flexibly changed to adapt to cables of different diameters. Specifically, for thicker cables, the spacing between adjacent fixed blocks 5 can be increased so that the positioning clamp 6 can be fully opened to accommodate the cables; for thinner cables, the spacing between adjacent fixed blocks 5 can be reduced accordingly to ensure the stable clamping of the cables. In addition, a movable ring 2 capable of rotating with the axis of the base 1 as the rotation center is arranged in the movable groove 11 on the outer peripheral surface of the base 1, and the bracket 3 is arranged on the outer wall of the movable ring 2 and extends along the radial direction of the base 1, so that the sliding sleeve of the slide 4 on the bracket 3 can be adjusted in the circumferential direction and radial direction. It should be noted that in complex power line layouts, such as when overhead transmission lines pass through mountainous areas or areas with dense buildings, cables may need to be laid around obstacles or at a specific angle. Through the rotation of the movable ring 2 and the radial extension of the bracket 3, the direction and position of the cable can be accurately adjusted to ensure that the cable is accurately positioned in three-dimensional space, effectively improving the flexibility and adaptability of power line laying and ensuring the stable operation of the power system.

[0025] The base 1 is roughly cylindrical and is the basic supporting component of the entire electric hardware. A movable groove 11 is provided on its outer peripheral surface to provide space and track for the subsequent installation and movement of the movable ring 2.

[0026] Specifically, in actual application, when the movable ring 2 is placed in the movable groove 11, the movable ring 2 can rotate with the axis of the base 1 as the rotation center, so that the bracket 3 connected to the movable ring 2 has circumferential adjustability. It can be understood that when the power line is turned at a certain angle on the horizontal plane, the bracket 3 and the cable fixed on the bracket 3 can be easily driven to achieve fine adjustment of the angle through the rotation of the movable ring 2, so as to better adapt to the changes in the line layout, avoid damage to the cable due to forced bending, and ensure the stability and safety of power transmission.

[0027] Among them, the bracket 3 is fixedly arranged on the outer wall of the movable ring 2, and its extension direction is consistent with the radial direction of the base 1, so that the bracket 3 has sufficient length, so as to provide accommodation space for multiple cables, ensuring that multiple cables can be fixed on the same power fitting at the same time, effectively improving the integration and efficiency of cable fixing. At the same time, it is also possible to change the distance between the cable and the base 1 to adapt to different installation environments and cable layout requirements, enhance the versatility and adaptability of the power fittings, and ensure the stable and reliable operation of the power system.

[0028] Specifically, the bracket 3 is provided with a mounting groove 31, which provides a basic structure for the installation of the slide 4. In practical applications, the bottom of the mounting groove 31 is provided with a plurality of positioning holes 32, which are used to cooperate with the fixing block 5 on the slide 4 to achieve accurate fixing and adjustment of the position of the slide 4. In this embodiment, the equidistant distribution of the plurality of positioning holes 32 can ensure the uniformity and flexibility of the position adjustment of the slide 4, so that the most suitable fixing position can be selected according to the specific conditions of the cable.

[0029] Among them, a plurality of slides 4 are slidably sleeved on the bracket 3, and the slides 4 can slide freely on the bracket 3 along the extension direction of the mounting groove 31, so that the number and position of the slides 4 can be flexibly configured according to the actual number and distribution of cables. For example, when multiple cables need to be fixed, the slides 4 can be slid to the corresponding position according to the spacing of the cables, so as to achieve independent fixing and precise positioning of each cable, and avoid mutual interference and friction between the cables.

[0030] Specifically, a fixing block 5 with movable characteristics in a direction perpendicular to the installation slot 31 is inserted on the slide 4. The first end of the fixing block 5 is adapted to the positioning hole 32. When the first end of the fixing block 5 is inserted into the positioning hole 32, it can effectively limit the unnecessary movement of the slide 4 in the extension direction of the installation slot 31, thereby providing a stable fixed position for the cable, ensuring that the cable will not be easily displaced after installation, thereby ensuring the stability and reliability of the cable fixing state. The second end of the fixing block 5 is connected to the positioning clamp 6 for clamping the cable to be fixed. The positioning clamp 6 can be made of a material with both moderate elasticity and sufficient strength, so that when fixing the cable, the positioning clamp 6 can not only tightly embrace the cable with its elasticity, provide a stable clamping force, and prevent the cable from loosening, but also use its strength to resist the interference of external environmental factors (such as wind, vibration, etc.) on the cable fixing state, while avoiding damage to the cable outer skin due to excessive extrusion, effectively ensuring the normal operation and service life of the cable, and maintaining the good electrical and mechanical properties of the cable. In practical applications, the coordination mechanism between the fixing block 5 and the positioning hole 32 greatly improves the flexibility of cable fixing, so that it can well adapt to the fixing requirements of cables of different diameters. When it is necessary to fix a thicker cable, by inserting the fixing block 5 into the appropriate positioning hole 32, the spacing between adjacent fixing blocks 5 is increased, so that the positioning clamp 6 connected thereto can be opened to a sufficiently large degree accordingly, thereby providing sufficient accommodation space for the thicker cable, ensuring that the cable can be stably and comfortably fixed on the bracket 3, and avoiding the situation where the cable is not fixed firmly or the cable is damaged due to the cable being too thick. On the contrary, for thinner cables, the fixing block 5 is inserted into the corresponding positioning hole 32, thereby reducing the spacing between adjacent fixing blocks 5. At this time, the positioning clamp 6 will fit closely to the outer wall of the cable, accurately and firmly clamp the cable, effectively preventing any slight loosening, displacement or shaking of the cable on the bracket 3, ensuring that the cable always maintains a stable fixed state during long-term operation, reducing potential safety hazards caused by unstable cable fixing, such as poor contact, arc discharge and other problems, and effectively ensuring the safe, stable and efficient operation of the power system.

[0031] In some possible implementations disclosed in this application, see Figure 1 As shown, at least two brackets 3 are provided, and the at least two brackets 3 are arranged opposite to each other along the axial direction of the base 1 , and mounting grooves 31 are provided on the sides of the at least two brackets 3 facing away from each other.

[0032] In this embodiment, at least two brackets 3 can provide more installation positions for fixing cables compared to a single bracket 3, greatly improving the cable bearing capacity of the power fittings and effectively meeting the needs of fixing multiple cables. At the same time, the installation slots 31 are opened on the sides that are separated from each other, providing more options for the layout of cables. Cables can be arranged in different installation slots 31 according to actual line planning, making the distribution of cables around the base 1 more reasonable, and facilitating the distinction and management of different types of cables, thereby improving the flexibility of the layout of power lines.

[0033] Furthermore, at least two brackets 3 may also be arranged as follows: At least two brackets 3 form an angle of 90° in the circumferential direction of the base 1 , and mounting grooves 31 are formed on the upper surface and / or the lower surface of at least two brackets 3 .

[0034] Here, at least two brackets 3 are arranged at a 90° angle on the circumference of the base 1, which can more effectively utilize the space around the base 1. Compared with the method of relatively arranged brackets 3, cables can be fixed at different angles and directions, and mutual interference between cables can be avoided. At the same time, when the upper surface and / or the lower surface of the bracket 3 is provided with a mounting groove 31, the direction of the cable can be more diversified, so as to better fit the actual equipment layout and power transmission path.

[0035] In some possible implementations disclosed in this application, see Figure 3 As shown, the first end of the fixing block 5 has an external thread, the inner wall of the positioning hole 32 has an internal thread, and the first end of the fixing block 5 is connected to the positioning hole 32 through the external thread and the internal thread.

[0036] In this embodiment, the threaded connection can form a tight fit between the fixing block 5 and the positioning hole 32. Compared with a simple plug-in connection, the meshing of the threads can provide greater friction and axial tension, thereby more effectively limiting the movement of the fixing block 5 in the positioning hole 32, ensuring that the fixing block 5 will not easily fall out of the positioning hole 32, thereby ensuring the stability of the position of the slide 4 and providing reliable fixed support for the cable.

[0037] In some possible implementations disclosed in this application, see Figure 3 As shown, the second end of the fixing block 5 is provided with a rotating connection piece, and the positioning clamp 6 includes a first clamp body and a second clamp body, and the first clamp body and the second clamp body are rotatably connected to the second end of the fixing block 5 through the rotating connection piece.

[0038] In this embodiment, when the first clamp body and the second clamp body of the positioning clamp 6 are rotatably connected to the second end of the fixing block 5 via the rotating connector, the positioning clamp 6 can better adapt to cables of different shapes and diameters.

[0039] The rotating connection piece may be a rotating sleeve or a ball and socket joint.

[0040] Specifically, when installing the cable, the rotationally connected positioning clamp 6 can be conveniently opened and closed. The operator can place the cable between the first clamp and the second clamp, and then close the positioning clamp 6 by rotating the first clamp and the second clamp, thereby completing the fixing of the cable. When the cable needs to be removed, the positioning clamp 6 can also be easily opened, which makes the operation process more convenient and improves work efficiency.

[0041] In some possible implementations disclosed in this application, see Figure 3 As shown, a clamping plate 51 is fixedly provided on the outer wall of the fixing block 5, and the working state of the clamping plate 51 includes a first state and a second state. When the clamping plate 51 is in the first state, the first end of the fixing block 5 is inserted into the positioning hole 32, and the clamping plate 51 abuts against the side wall of the mounting groove 31. When the clamping plate 51 is in the second state, the first end of the fixing block 5 is disengaged from the positioning hole 32, and the clamping plate 51 is separated from the side wall of the mounting groove 31.

[0042] In this embodiment, when the card plate 51 is in the first state, that is, the card plate 51 is abutting against the side wall of the installation groove 31, the card plate 51 can provide additional supporting force in a direction perpendicular to the axial direction of the fixing block 5, which helps to prevent the fixing block 5 from unnecessary shaking or rotation in the positioning hole 32 when subjected to lateral external force (such as the force generated by the shaking of the cable or the collision force during the installation process), thereby ensuring the stability of the position of the fixing block 5 in the positioning hole 32, thereby ensuring the reliability of the cable fixation.

[0043] Among them, in some specific examples, when the first end of the fixed block 5 is connected to the positioning hole 32 by means of external threads and internal threads, the clamping plate 51 is rotatably connected to the fixed block 5, and the fixed block 5 can rotate relative to the clamping plate 51; in other specific examples, when the first end of the fixed block 5 is plugged into the positioning hole 32, the clamping plate 51 and the fixed plate are integrally formed.

[0044] Specifically, the first end of the fixed block 5 is plugged into the positioning hole 32, and the card plate 51 and the fixed plate are integrally formed as an example for explanation. When the fixed block 5 needs to be installed in the positioning hole 32, first align the first end of the fixed block 5 with the positioning hole 32, and then apply a certain thrust along the axial direction of the positioning hole 32 to gradually insert the fixed block 5 into the positioning hole 32. As the fixed block 5 is inserted, the card plate 51 will gradually approach the side wall of the mounting groove 31. When the first end of the fixed block 5 is fully inserted into the positioning hole 32 and reaches the predetermined installation position, the card plate 51 just abuts tightly against the side wall of the mounting groove 31. When the fixed block 5 needs to be disassembled, for example, when maintaining the cable, replacing the cable, or adjusting the cable fixing layout, the fixed block 5 needs to be removed from the positioning hole 32. At this time, the card plate 51 is converted from the first state of abutting against the side wall of the mounting groove 31 to the second state of separation.

[0045] In some possible implementations disclosed in this application, see Figure 4 As shown, the bracket 3 includes a fixed end connected to the movable ring 2 and a yielding end for mounting the slide 4. A slot 21 is provided on the movable ring 2 at a position relative to the yielding end. A telescopic slot 33 is provided at the yielding end. A push plate 34 is slidably provided in the telescopic slot 33. An elastic member 35 and an insertion rod 36 are provided on both sides of the push plate 34. The insertion rod 36 is located on a side of the push plate 34 close to the movable ring 2. The insertion rod 36 is used to cooperate with the elastic member 35 to penetrate the bracket 3 and insert into the slot 21. The telescopic slot 33 is provided with a push plate 34. The push plate 34 is provided with an elastic member 35 and an insertion rod 36. The insertion rod 36 is provided with an elastic member 35 to penetrate the bracket 3 and insert into the slot 21. At least one side is open to form a movable opening 37, and the push plate 34 is rotatably connected to the pull plate 38 through the movable opening 37. The working states of the pull plate 38 include a third state and a fourth state. When the pull plate 38 is in the third state, the pull plate 38 is coplanar with the push plate 34, and the pull plate 38 is used to cooperate with the push plate 34 to compress the elastic member 35. When the pull plate 38 is in the fourth state, the pull plate 38 is perpendicular to the push plate 34, and the pull plate 38 is used to cooperate with the movable opening 37 to allow the slide 4 to pass through.

[0046] In this embodiment, when there is an actual need to fix more cables on a single bracket 3. First, manually rotate the pull plate 38 to the third state, in which the pull plate 38 and the push plate 34 are in the same plane. By applying a force in the direction away from the movable ring 2 to the pull plate 38, the force is transmitted to the push plate 34, thereby compressing the elastic member 35 located on one side of the push plate 34. With the compression of the elastic member 35, the insertion rod 36 originally inserted into the slot 21 of the movable ring 2 can be withdrawn from the slot 21, thereby effectively disconnecting the connection between the yield end of the bracket 3 and the movable ring 2, creating a gap space for operation, so as to introduce the additional slide 4 later. Next, rotate the pull plate 38 to the fourth state, at which time the pull plate 38 and the push plate 34 are arranged vertically, and the pull plate 38 and the movable opening 37 cooperate with each other to form an obstacle-free passage that allows the slide 4 to pass smoothly. By using this channel, the newly added slide 4 is introduced from the yielding end of the bracket 3, and moved along the channel to the position where the mounting groove 31 is pre-set on the bracket 3, ensuring that the slide 4 can be accurately positioned to prepare for the subsequent cable fixation. Finally, after the newly added slide 4 is in place, the elastic potential energy accumulated by the previous compression of the elastic member 35 begins to be released, and the elastic member 35 will generate a thrust in the direction of the movable ring 2. This thrust acts on the push plate 34, and then pushes the insertion rod 36 to be inserted into the slot 21 of the movable ring 2 again, so as to achieve the reconnection and stabilization of the yielding end of the bracket 3 and the movable ring 2. In this way, a reliable basic support is provided for the subsequent fixation of more cables, fully meeting the diverse needs of power hardware in multiple cable fixation scenarios, and effectively ensuring that the power lines can be stably and efficiently laid and safely operated in various complex environments.

[0047] The bracket 3 includes a fixed end and a yielding end, wherein the fixed end is used to connect the movable ring 2, and the connection method may be welding, etc., so as to achieve relative fixation between the bracket 3 and the movable ring 2, and ensure that the bracket 3 can rotate with the rotation of the movable ring 2. The yielding end is detachably connected to the movable ring 2, and is used to install the slide 4, so that the power fittings can adjust the number of slides 4 on the bracket 3 according to actual conditions, that is, the number of fixed cables.

[0048] Specifically, a slot 21 is provided on the movable ring 2 at a position relative to the yielding end of the bracket 3. A telescopic slot 33 is provided at the yielding end of the bracket 3, and a slidable push plate 34 is provided in the telescopic slot 33. Elastic members 35 and insertion rods 36 are provided on both sides of the push plate 34, respectively, and the insertion rod 36 is located on the side of the push plate 34 close to the movable ring 2. The elastic member 35 provides elastic force for the insertion rod 36, so that the insertion rod 36 can be inserted into the slot 21 of the movable ring 2 under normal circumstances, thereby firmly connecting the yielding end of the bracket 3 and the movable ring 2 together, ensuring the stability of the bracket 3 under normal working conditions, and enabling the bracket 3 to effectively carry the slide 4 and the cable. Furthermore, at least one side of the telescopic slot 33 is open to form a movable opening 37, and the push plate 34 is rotatably connected to the pull plate 38 through the movable opening 37. The pull plate 38 has two working states, including a third state and a fourth state. When more cables need to be fixed on a single bracket 3 and a new slide 4 is to be introduced, the pull plate 38 is manually rotated to the third state, that is, the pull plate 38 is coplanar with the push plate 34. At this time, a force is applied to the pull plate 38 in the direction away from the movable ring 2, and this force is transmitted to the push plate 34, so that the push plate 34 moves in the direction away from the movable ring 2, thereby compressing the elastic member 35 located on one side of the push plate 34. With the compression of the elastic member 35, the insertion rod 36 can be withdrawn from the slot 21 of the movable ring 2, thereby disconnecting the connection between the yielding end of the bracket 3 and the movable ring 2, and creating a gap space between the yielding end of the bracket 3 and the movable ring 2. This gap space is for the convenience of the subsequent introduction of the new slide 4, because if there is no gap, the new slide 4 may be hindered and cannot be installed on the bracket 3. After the insertion rod 36 withdraws from the slot 21 and the yielding end of the bracket 3 introduces the slide 4, the pull plate 38 is rotated to the fourth state, at which time the pull plate 38 and the push plate 34 are arranged vertically. The pull plate 38 cooperates with the movable opening 37 to form an unobstructed passage. Through this passage, the newly added slide 4 can be introduced from the yielding end of the bracket 3, and the slide 4 can be moved along the passage to the position where the mounting groove 31 is pre-set on the bracket 3. In this way, the operation of adding a slide 4 to the bracket 3 is realized, which provides conditions for fixing more cables. After the newly added slide 4 is in place, the elastic member 35 that was previously compressed will release elastic potential energy and generate a thrust in the direction of the movable ring 2. This thrust acts on the push plate 34, pushing the insertion rod 36 to be inserted into the slot 21 of the movable ring 2 again, reconnecting and stabilizing the yielding end of the bracket 3 and the movable ring 2. In this way, the bracket 3 is restored to a state where it can work normally, and can provide reliable support for the newly added slide 4 and cables, meet the needs of fixing multiple cables, and ensure the stability of the laying and operation of power lines.

[0049] In some possible implementations disclosed in this application, see Figure 2As shown, a plurality of limiting holes 12 are formed at the bottom of the movable groove 11 along the circumferential direction of the movable ring 2 . A limiting rod 22 is movably provided on the movable ring 2 . The limiting rod 22 penetrates the movable ring 2 and extends along the radial direction of the movable ring 2 .

[0050] In this embodiment, when the movable ring 2 rotates in the movable groove 11 , the rotation range of the movable ring 2 can be limited by inserting the limiting rod 22 into the limiting holes 12 at different positions.

[0051] The movable ring 2 is provided with an insertion hole, and the limiting rod 22 can be inserted into the insertion hole and can slide in the insertion hole to achieve movement along the radial direction of the movable ring 2.

[0052] Specifically, in actual application, when the cable has been adjusted to a suitable angle, the limit rod 22 is inserted into the corresponding limit hole 12 to fix the position of the movable ring 2 and prevent the movable ring 2 from rotating unnecessary due to external forces (such as wind, vibration, etc.), thereby ensuring that the direction and position of the cable remain stable.

[0053] The length of the limiting rod 22 is greater than the thickness of the movable ring 2 .

[0054] Specifically, in actual application, after the limit rod 22 passes through from one side of the movable ring 2 to the other side, part of the rod body still extends out of the outer side of the movable ring 2. The extended part of the rod body is equipped with a pull-out frame, which is connected to the extended limit rod 22, and its function is to facilitate the operator to operate the limit rod 22. It is understandable that when the position of the limit rod 22 needs to be adjusted, the operator can apply force by holding the pull-out frame, so as to easily pull out or insert the limit rod 22 from the corresponding hole on the movable ring 2, so as to achieve precise control and adjustment of the rotation state of the movable ring 2, thereby meeting the requirements of the power fittings for the fixed angle and position of the cable under different working conditions, and ensuring the stable and safe operation of the power line.

[0055] In some possible implementations disclosed in this application, see Figure 2 As shown, a plurality of balls 23 are evenly arranged on the inner wall of the movable ring 2 along the circumferential direction of the movable ring 2 , and the outer walls of the plurality of balls 23 are in contact with the bottom of the movable groove 11 .

[0056] In this embodiment, when the movable ring 2 rotates in the movable groove 11, the presence of the ball 23 can convert the sliding friction between the movable ring 2 and the bottom of the movable groove 11 into rolling friction. The friction force of rolling friction is much smaller than that of sliding friction, which makes the movable ring 2 smoother during rotation.

[0057] In some possible implementations disclosed in this application, see Figure 5As shown, the power fittings also include a U-shaped rod 7, which is arranged on the top of the base 1, and the U-shaped rod 7 is used to fix the base 1 and the external supporting structure; wherein, a connecting seat 8 is relatively arranged on the upper surface of the base 1 along the radial direction of the base 1, and a screw 9 is threaded in the connecting seat 8, and a movable block 10 is rotatably connected to the end of the screw 9 away from the connecting seat 8, and the movable block 10 is connected to the U-shaped rod 7; wherein, the base 1 and the U-shaped rod 7 are made of carbon steel, and the outer surfaces of the base 1 and the U-shaped rod 7 are sprayed with a wear-resistant and corrosion-resistant layer.

[0058] Among them, in actual applications, the external supporting structure can be a telephone pole, a tower, etc., and the U-shaped rod 7 can act like a "hook" to firmly mount the power fittings on these supporting structures, providing a reliable foundation for supporting and fixing the cables.

[0059] Specifically, a screw rod 9 is screwed in a connection seat 8 which is arranged relatively in the radial direction on the upper surface of the base 1, and the end of the screw rod 9 away from the connection seat 8 is rotated to connect the movable block 10, and the movable block 10 is connected to the U-shaped rod 7. This structure allows the position of the U-shaped rod 7 to be adjusted. By rotating the screw rod 9, since the screw rod 9 and the connection seat 8 are in a screw connection relationship, the screw rod 9 will produce an axial displacement, thereby pushing or pulling the movable block 10. The movement of the movable block 10 will change the position of the U-shaped rod 7, thereby flexibly adjusting the installation position of the U-shaped rod 7 according to the specific shape and size of the external support structure and the installation requirements of the power fittings, ensuring that the power fittings are tightly and firmly connected to the external support structure. In addition, a rubber ring can be set at the open part of the connection seat 8, and a rubber gasket can be set at the bottom of the screw rod 9. The rubber ring and the rubber gasket can be used to increase the sealing between the screw rod 9 and the connection seat 8, and prevent rainwater from penetrating and causing rust on the threads, which affects the tightness of the connection.

[0060] The base 1 and the U-shaped rod 7 are made of carbon steel. Carbon steel has high strength and toughness and can withstand large weight and external forces. During the use of the power fittings, whether it is the weight of the cable itself or the external forces such as wind load and vibration that may be suffered, the base 1 and the U-shaped rod 7 made of carbon steel can provide sufficient support to ensure the structural stability of the power fittings.

[0061] Specifically, the outer surfaces of the base 1 and the U-shaped rod 7 are sprayed with a wear-resistant and corrosion-resistant layer, which can be achieved through surface modification technologies such as laser surface alloying and laser cladding. In outdoor environments, electrical hardware will be affected by natural factors such as wind, sun, and rain for a long time. The wear-resistant and corrosion-resistant layer can effectively prevent the surface of the base 1 and the U-shaped rod 7 from being worn, for example, preventing wind and sand from scratching their surfaces. At the same time, the coating can also resist corrosion. The erosion of carbon steel by corrosive substances such as acid rain will be blocked by the coating, thereby extending the service life of the electrical hardware and reducing the hidden dangers of power safety caused by material damage.

[0062] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
