Description

Technical Field

[0001] This application relates to the field of power fittings technology, and in particular to a telescopic adjustable power fitting. Background Technology

[0002] Power fittings are metal accessories used in power systems to connect, fix, protect, or support components such as conductors, insulators, and towers. They are components of power transmission and distribution networks. Types include suspension clamps, tension clamps, connecting fittings, and protective fittings (such as vibration dampers and grading rings). They are mostly made of high-strength aluminum alloys, galvanized steel, or copper alloys, and must possess corrosion resistance, aging resistance, and high mechanical strength. Power fittings are designed to meet electrical performance (such as voltage equalization and corona prevention) and mechanical load requirements to ensure the safe and stable operation of lines. They are widely used in overhead lines, substations, and cable systems and are an indispensable part of power infrastructure. Traditional fittings use fixed-size slots and holes with a preset fixed inner diameter. If the cable diameter is smaller than the slot, it is easy to loosen. They can only accommodate the installation needs of a single line and have poor adaptability to different cable specifications. Furthermore, they are cumbersome to operate during high-altitude installations, increasing construction difficulty and safety risks. To address these issues, we have innovatively developed telescopic adjustable power fittings that can flexibly adapt to the installation requirements of multiple line specifications.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Reference Figure 1-4 This utility model provides a telescopic adjustable power fitting, including a mounting block 1, a partition block 101 fixedly connected to the middle of the mounting block 1, a bolt rod B301 fixedly connected to the top of the mounting block 1, a nut 302 threadedly connected to the surface of the bolt rod B301, a wire pressing block 3 provided at the bottom of the nut 302, the middle of the wire pressing block 3 passing through the bolt rod B301 and slidably connected to it, the bottom of both sides of the wire pressing block 3 is provided with arc grooves 303, a sliding movable plate 304 is slidably connected to the top of the mounting block 1, a fixed plate 305 is fixedly connected to one side of the movable plate 304, the top of the fixed plate 305 is provided with multiple connecting holes A306, and both sides of the top of the mounting block 1 are provided with multiple connecting holes B307, the connecting holes B307 and the connecting holes A306 are connected by bolts.

[0020] During power line installation, the cable is placed inside the mounting block 1. The nut 302 on the bolt rod B301, with a pressure block 3 at its bottom, pushes the pressure block 3 downwards as the nut 302 is screwed down. The pressure block 3 has arc grooves 303 on both sides at its bottom, allowing the cable to fall into these grooves. As the pressure block 3 continues to press down, the cable is firmly secured. Simultaneously, the movable plate 304 can be extended according to the actual weight of the line. After moving the movable plate 304 to the appropriate position, the connecting hole B307 is aligned with the connecting hole A306, and then bolts are passed through the corresponding connecting holes for connection and fixation, thus completing the installation and adjustment of the power fitting.

[0021] Using the wire clamping block 3 in conjunction with the mounting block 1, two cables can be fixed at the same time, which improves installation efficiency and saves space. At the same time, the movable plate 304 is telescopic and adjustable, allowing installers to flexibly adjust the spacing of the support points or the overall length of the hardware according to the actual weight and tension of the line.

[0022] In a preferred embodiment, the inner wall of the mounting block 1 is provided with a guide groove 308, and the movable plate 304 is fixedly provided with a guide block on the side facing the inner wall of the mounting block 1 and slidably connected with the guide groove 308.

[0023] The sliding fit between the guide block and the guide groove 308 provides guidance for the movement of the movable plate 304, ensuring that the sliding process of the movable plate 304 is smooth.

[0024] In a preferred embodiment, a support block 2 is fixedly connected to the top of the mounting block 1, a bolt rod A2031 is threadedly connected to the top of the support block 2, a rotating rod 203 is fixedly connected to the top of the bolt rod A2031, a connecting block 201 is fixedly connected to the top of the bolt rod A2031, bushings 202 are fixedly connected to both sides of the connecting block 201, a threaded post 204 is threadedly connected to the inside of the bushing 202, a pressing block 205 is attached to the bottom of the threaded post 204, a limiting block 2051 is fixedly connected to one side of the pressing block 205, and limiting grooves 206 are provided on both sides of the support block 2, with the limiting grooves 206 and the limiting blocks 2051 slidably connected.

[0025] The support block 2 at the top of mounting block 1 provides support for the upper structure. Rotating the rotating rod 203 causes the bolt rod A2031 to rotate threadedly on the top of the support block 2, thereby adjusting the height of the connecting block 201. The threaded posts 204, which are threadedly connected to the bushings 202 on both sides of the connecting block 201, will press down on the pressing block 205 when rotated. The limiting block 2051 on one side of the pressing block 205 slides along the limiting grooves 206 on both sides of the support block 2, ensuring that the pressing block 205 presses down vertically. The height of the connecting block 201 can be adjusted by the bolt rod A2031. The cooperation between the threaded post 204 and the pressing block 205 further ensures a secure connection of the cable. The limiting block 2051 and the limiting groove 206 ensure stable movement of the pressing block 205, thus improving the adjustment range and fixing reliability of the hardware.

[0026] In a preferred embodiment, an elastic anti-slip layer is provided on the inner surface of the arc groove 303.

[0027] The elastic anti-slip layer on the inner surface of the arc groove 303 at the bottom of the wire clamping block 3 will fit tightly against the surface of the wire when the arc groove 303 comes into contact with the wire, and will deform by its own elasticity.

[0028] In a preferred embodiment, the connecting holes B307 are arranged in multiple linear groups on the top of the mounting block 1, each group containing two connecting holes B307, and two groups of connecting holes A306 are correspondingly provided on the fixing plate 305.

[0029] The connecting holes B307 on the top of the mounting block 1 are arranged in multiple linear groups, with each group containing two connecting holes B307. The connecting holes A306 on the fixing plate 305 are set in two corresponding groups. By selecting different groups of connecting holes A306 and connecting holes B307 for bolt connection, the telescopic length of the movable plate 304 can be adjusted, expanding the telescopic range and adapting to more different installation needs.

[0030] In a preferred embodiment, the mounting block 1, the partition block 101, the movable plate 304, and the fixed plate 305 are all made of aluminum alloy and coated with an insulating coating with a thickness of 0.3-0.5 mm. The aluminum alloy material makes the electrical fittings lightweight and sturdy, while the insulating coating improves the safety and reliability of the electrical fittings.

[0031] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a telescopic adjustable power fitting provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
