Description

Technical Field

[0001] This utility model belongs to the technical field of cable connection hardware, and in particular relates to a high-strength connection hardware for cable accessories. Background Technology

[0002] Connecting hardware is a type of power fitting, mainly used to connect components such as conductors, lightning protection wires, and insulators in overhead power lines to ensure the safe and reliable operation of the lines. It has sufficient strength and rigidity to withstand loads such as conductor tension, wind force, and icing, and will not deform or break during long-term operation.

[0003] For example, Chinese patent CN216056232U discloses a cable connection hardware string, including a U-shaped hanging ring, an extension ring, a heart-shaped ring, and pre-twisted wire. One end of the U-shaped hanging ring is connected to a pole, and the other end is connected to an adjusting ring. The other end of the adjusting ring is connected to one end of the extension ring, and the other end of the extension ring is connected to the heart-shaped ring. The other end of the heart-shaped ring is connected to the pre-twisted wire, which is connected to a cable. The adjusting ring includes a sleeve and a telescopic rod. The telescopic rod is slidably and / or rotatably connected to the sleeve. One end of the sleeve is connected to the U-shaped hanging ring, and the other end of the telescopic rod is connected to the extension ring. This device uses an adjustable adjusting ring, which allows for adjustment of the angle and length of the hardware string pre-connected on the ground. This facilitates cable connection work without the need for disassembly of the hardware string and also benefits subsequent cable connection maintenance.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use, such as: after adjusting the length of the fitting, the device only uses a single locking pin for limiting it. The limiting strength of a single locking pin is low, and the pin is not effectively fixed, which can easily lead to the pin derailing. Therefore, it is not suitable for connecting high-strength cable accessories. In view of this, we propose a high-strength connecting fitting for cable accessories. Utility Model Content

[0006] The purpose of this invention is to provide a high-strength connecting fitting for cable accessories to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a high-strength connecting fitting for cable accessories, comprising:

[0008] A circular plate is provided. A connecting rod is fixedly installed on one side of the circular plate. A sliding groove is provided in the connecting rod. A sliding rod is slidably installed in the sliding groove. A circular plate is provided at one end of the connecting rod. One end of the sliding rod passes through one side of the sliding groove and the circular plate and is fixedly installed with a limiting plate. A sliding groove is provided in the sliding rod. Sliding blocks are symmetrically slidably installed in the sliding groove. Several limiting holes are symmetrically provided on the periphery of the connecting rod. One end of the sliding block passes through one side of the sliding groove and extends into the corresponding limiting hole. Two springs are fixedly installed between two sliding blocks.

[0009] A limiting component, which is located on the sliding rod and is used to limit the sliding rod;

[0010] Two threaded rods are threadedly mounted on a circular plate. One end of each threaded rod is fixedly mounted with a round rod. One end of the round rod passes through the other end of the connecting rod, the sliding block, and several limiting holes. A connecting ring one and a connecting ring two are fixedly mounted on opposite sides of the circular plates.

[0011] In this technical solution, a person can pull the second connecting ring, which will move the second circular plate. The second circular plate will then move the sliding rod through the limiting plate, causing the sliding rod to slide outward within the sliding groove. Simultaneously, the limiting component can limit the sliding rod, ensuring it does not rotate during movement, until the sliding rod extends to the appropriate length. At this point, under the rebound force of the two springs, the two springs will compress the two sliding blocks, causing them to move away from each other until one end of each sliding block is inserted into the corresponding limiting hole. At this point, the two sliding blocks can limit the sliding rod. Then, the person inserts two round rods into the first circular plate and the connecting rod, so that one end of each round rod passes through the sliding block. Then, rotating the two threaded rods, under the action of the threads, can fix the two round rods, which in turn limit the two sliding blocks, ensuring they cannot be pressed. This allows for easy adjustment of the connecting rod length while preventing the two sliding blocks from loosening, thus strengthening the overall device.

[0012] In the above technical solution, the limiting component further includes:

[0013] Two limiting grooves are symmetrically opened on the inner wall of the sliding groove, and limiting blocks are fixedly installed on the periphery of the sliding rod and in the two limiting grooves respectively.

[0014] In this technical solution, the movement of the sliding rod also drives the two limiting blocks to move. Under the limiting effect of the two limiting grooves, it can be ensured that the sliding rod will not rotate when it moves.

[0015] In the above technical solution, the limiting block is further slidably connected to the limiting groove.

[0016] In this technical solution, it is ensured that the limiting block can slide normally within the limiting groove.

[0017] In the above technical solution, the circular plate is rotatably connected to one end of the sliding rod, and one end of the sliding block is inserted into the limiting hole.

[0018] In this technical solution, it is ensured that the second circular plate can rotate normally at one end of the sliding rod, and that one end of the sliding block can be inserted into the limiting hole.

[0019] In the above technical solution, one end of the round rod is further engaged with the round plate, the connecting rod, and the sliding block.

[0020] In this technical solution, it is ensured that one end of the round rod can be inserted into the round plate, the connecting rod, and the sliding block.

[0021] In the above technical solution, the first connecting ring is tightly welded to the first circular plate, and the second connecting ring is tightly welded to the second circular plate.

[0022] In this technical solution, the structural stability of connecting ring one and connecting ring two is ensured.

[0023] In the above technical solution, furthermore, the plurality of limiting holes are linearly and equally spaced, and the cross-section of the sliding rod is T-shaped.

[0024] In this technical solution, the sliding rod can extend a greater distance to ensure that it will not fall out of the sliding groove.

[0025] The beneficial effects of this utility model are:

[0026] This cable accessory uses high-strength connecting hardware. Through the cooperation of the threaded rod, the round rod, two sliding blocks, two springs, and several limiting holes, it ensures that the length of the connecting rod can be easily adjusted by personnel. At the same time, it can prevent the two sliding blocks from becoming loose while adjusting the length of the connecting rod, thus strengthening the overall strength of the device.

[0040] Please see Figure 1 - Figure 6 As shown, this embodiment provides a high-strength connecting fitting for cable accessories, including:

[0041] A circular plate 1 has a connecting rod 2 fixedly installed on one side. A sliding groove 3 is opened in the connecting rod 2. A sliding rod 4 is slidably installed in the sliding groove 3. A circular plate 2 5 is provided at one end of the connecting rod 2. One end of the sliding rod 4 passes through one side of the sliding groove 3 and the circular plate 2 5 and is fixedly installed with a limiting plate 6. A sliding groove 7 is opened in the sliding rod 4. Sliding blocks 8 are symmetrically slidably installed in the sliding groove 7. Several limiting holes 10 are symmetrically opened on the periphery of the connecting rod 2. One end of the sliding block 8 passes through one side of the sliding groove 7 and extends into the corresponding limiting hole 10. Two springs 9 are fixedly installed between two sliding blocks 8.

[0042] A limiting component is located on the sliding rod 4 and is used to limit the sliding rod 4.

[0043] Two threaded rods 13 are threadedly mounted on circular plate 1. One end of each threaded rod 13 is fixedly mounted with a circular rod 14. One end of the circular rod 14 passes through the other end of the connecting rod 2, the sliding block 8, and several limiting holes 10. Connecting ring 15 and connecting ring 26 are fixedly mounted on the opposite sides of circular plate 1 and circular plate 2, respectively.

[0044] In this system, a person can pull the connecting ring 16, which will move the circular plate 5. The circular plate 5 will then move the sliding rod 4 through the limiting plate 6, causing the sliding rod 4 to slide outward within the sliding groove 3. Simultaneously, the limiting component can limit the sliding rod 4, ensuring that it does not rotate during movement, until the sliding rod 4 extends to the appropriate length. At this point, under the rebound force of the two springs 9, the two springs 9 will compress the two sliding blocks 8, causing them to move away from each other until one end of each sliding block 8 is inserted into the corresponding limiting hole 10. Two sliding blocks 8 can limit the sliding rod 4. Then, the operator inserts two round rods 14 into the round plate 1 and the connecting rod 2, so that one end of each round rod 14 passes through the sliding block 8. Then, the two threaded rods 13 are rotated. Under the action of the threads, the two round rods 14 can be fixed. The two round rods 14 can limit the two sliding blocks 8, ensuring that the two sliding blocks 8 cannot be pressed. This ensures that the operator can easily adjust the length of the connecting rod 2. At the same time, it can also prevent the two sliding blocks 8 from becoming loose while adjusting the length of the connecting rod 2, thus strengthening the overall strength of the device.

[0046] Two limiting grooves 11 are symmetrically opened on the inner wall of the sliding groove 3. Limiting blocks 12 are fixedly installed on the periphery of the sliding rod 4 and in the two limiting grooves 11 respectively.

[0047] The movement of the sliding rod 4 will also cause the two limiting blocks 12 to move. Under the limiting effect of the two limiting grooves 11, it can be ensured that the sliding rod 4 will not rotate when it moves. Example 3

[0048] This embodiment provides a high-strength connecting fitting for cable accessories. In addition to the technical solution of the above embodiment, it also has the following technical features: the limiting block 12 and the limiting groove 11 are slidably connected.

[0049] This ensures that the limiting block 12 can slide normally within the limiting groove 11. Example 4

[0053] Specifically, it is ensured that one end of the round rod 14 can be inserted into the round plate 1, the connecting rod 2, and the sliding block 8. Example 6

[0054] This embodiment provides a high-strength connecting fitting for cable accessories. In addition to the technical solution of the above embodiment, it also has the following technical features: connecting ring 15 is tightly welded to round plate 1, and connecting ring 16 is tightly welded to round plate 5.

[0055] Among these measures, it is essential to ensure the structural stability of connecting ring 15 and connecting ring 2 16. Example 7

[0056] This embodiment provides a high-strength connecting fitting for cable accessories. In addition to the technical solution of the above embodiment, it also has the following technical features: a plurality of limiting holes 10 are linearly and equally spaced, and the cross-section of the sliding rod 4 is T-shaped.

[0057] In particular, it is necessary to ensure that the sliding rod 4 can extend a greater distance to prevent it from falling out of the sliding groove 3.

[0058] Working principle: When the length of connecting rod 2 needs to be adjusted, the operator can first rotate the two threaded rods 13 respectively. Under the action of the threads, the threaded rods 13 will move on the circular plate 1. At the same time, the movement of the threaded rods 13 will drive the circular rod 14 to move, thereby pulling the circular rod 14 out from the connecting rod 2, the sliding block 8, and the circular plate 1. At this time, the two sliding blocks 8 can be released from their limits. The operator can press the two sliding blocks 8, so that the two sliding blocks 8 move closer to each other and squeeze the two springs 9 to retract, until one end of the two sliding blocks 8 moves out of the corresponding limiting hole 10. At this time, the two sliding blocks 8 can release the limiting of the sliding rod 4. The operator can pull the connecting ring 16. The connecting ring 16 will drive the circular plate 5 to move, and the circular plate 5 will drive the sliding rod 4 to move through the limiting plate 6, so that the sliding rod 4 slides outward in the sliding groove 3. At the same time, the movement of the sliding rod 4 will also drive the two limiting blocks 12 to move in the two limiting grooves 1. Under the effect of the limit, the sliding rod 4 can be guaranteed not to rotate when moving until the sliding rod 4 extends to a suitable length. At this time, under the action of the rebound force of the two springs 9, the two springs 9 will squeeze the two sliding blocks 8, causing the two sliding blocks 8 to move away from each other until one end of the two sliding blocks 8 is inserted into the corresponding limit hole 10. At this time, the two sliding blocks 8 can limit the sliding rod 4. Then, the operator inserts the two round rods 14 into the round plate 1 and the connecting rod 2, so that one end of the two round rods 14 passes through the sliding block 8 respectively. Then, the two threaded rods 13 are rotated. Under the action of the threads, the two round rods 14 can be fixed. The two round rods 14 can limit the two sliding blocks 8, ensuring that the two sliding blocks 8 cannot be pressed. This ensures that the operator can easily adjust the length of the connecting rod 2. At the same time, it can also prevent the two sliding blocks 8 from loosening while adjusting the length of the connecting rod 2, thus strengthening the overall strength of the device.

[0059] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
