Description

Technical Field

[0001] This utility model relates to the field of wire clip technology, and in particular to a multifunctional hinge wire clip. Background Technology

[0002] In power transmission and distribution systems, wire clamps, as key components connecting conductors, insulators, and other electrical equipment, play a crucial role in ensuring the safe and stable operation of the power system. However, existing wire clamp products often struggle to withstand complex and variable stress environments in practical applications, easily leading to deformation and damage. This not only affects the service life of the clamp itself but also causes loose conductor connections, reducing power transmission efficiency and potentially triggering electrical faults, threatening the safety of electrical equipment and personnel. Furthermore, traditional wire clamps often use a single nut tightening method, lacking effective anti-loosening measures. Their grounding structure design is flawed, resulting in unreliable grounding connections. In the event of a fault, current cannot be quickly conducted to the ground, increasing the risk of electric shock and easily damaging electrical equipment. In addition, traditional wire clamps have poor installation and adjustment flexibility, making them difficult to adapt to complex and variable installation environments. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a multi-functional hinge clamp that is structurally stable, reliably anti-loosening, grounded safely, and easy to install, adjust, and monitor.

[0004] To achieve the above objectives, this utility model employs a multifunctional hinge clamp comprising at least two stranded wire assemblies. A spacer block is installed between the stranded wire assemblies. One end of the spacer block is provided with a grounding ring, and a shaft groove is provided at the end near the grounding ring. A drive shaft is inserted into the shaft groove. The grounding ring covers both ends of the drive shaft inserted into the shaft groove of the spacer block and is connected to the spacer block by screws. A first drive hinge block and a second drive hinge block are respectively sleeved on the drive shaft. Both the first and second drive hinge blocks extend at the ends away from the grounding ring. The first drive hinge block has a positioning hole at the end away from the grounding ring, and a pin is provided in the positioning hole. The second drive hinge block has a slot, in which a hinge bolt is engaged. One end of the hinge bolt is equipped with an anti-loosening fastening component, and the other end of the hinge bolt forms an inner hole, which is sleeved on the pin.

[0005] The beneficial effects of the above structure are as follows: the stranded wire assembly is connected in sequence through components such as spacers, drive shafts, drive hinge blocks, and hinge bolts to form a stable whole, which can effectively disperse stress. When subjected to external forces such as tension and pressure, the components work together to reduce the risk of deformation and damage and extend the service life of the clamp. The hinge bolt is fastened with a combination of nuts, spring washers, and flat washers. The spring washers provide elastic preload, and the flat washers increase the contact area and disperse pressure, so that the connection can remain firm under vibration and impact. The grounding ring at one end of the spacer block covers both ends of the drive shaft and is connected to the spacer block to ensure a reliable connection between the clamp and the grounding system. In case of a fault, the current is quickly conducted to the ground, effectively preventing electric shock and ensuring the safety of electrical equipment and personnel. The drive shaft is sleeved with the drive hinge block, and the inner hole of the hinge bolt is sleeved with a pin shaft, which enables flexible rotation and facilitates the opening and closing of the clamp.

[0006] This utility model further specifies that each stranded wire assembly includes stranded wires and insulating layers sleeved at both ends of the stranded wires. The stranded wires are steel-cored aluminum stranded wires. The steel core has high strength characteristics, ensuring that the wire clamp maintains structural stability under various complex stress environments. The aluminum wire portion has good conductivity, improving power transmission efficiency. The insulating layers sleeved at both ends of the stranded wires effectively isolate the stranded wires from the external environment, ensuring the safe and stable operation of the power system.

[0007] This utility model is further configured with an anti-loosening fastening assembly including a nut, a spring washer, and a flat washer. The spring washer and the flat washer are sequentially fitted onto the hinge bolt, and the nut is screwed onto the end of the hinge bolt. The anti-loosening fastening assembly effectively prevents the nut from loosening, ensuring a good electrical connection between the clamp and components such as conductors, reducing the probability of electrical faults, and improving the safety and reliability of the power system.

[0008] This utility model further features a rotatable, gourd-shaped aluminum spacer block with a temperature measuring hole. The rotatable gourd shape of the spacer block allows for flexible angle adjustment during installation and better disperses the force exerted by the stranded wire on the spacer block, resulting in a more uniform stress distribution. This enhances the structural strength and stability of the spacer block, extends its service life, and the pre-drilled temperature measuring hole facilitates real-time monitoring of the internal temperature of the clamp.

[0015] like Figures 1-6 As shown, an embodiment of this utility model provides a multifunctional hinge clamp, comprising two stranded wire assemblies 1. Each stranded wire assembly 1 consists of stranded wire 11 and an insulating layer 12 sleeved at both ends of the stranded wire 11. The stranded wire 11 is made of steel-cored aluminum stranded wire. Between the two stranded wire assemblies 1, a rotatable gourd-shaped aluminum spacer block 2 is installed. One end of the spacer block 2 is provided with a grounding ring 3, and two shaft grooves 21 are provided at the end near the grounding ring 3. A drive shaft 22 is inserted into both shaft grooves 21. The grounding ring 3 covers both ends of the drive shaft 22 inserted into the shaft grooves 21 of the spacer block 2 and is tightly connected to the spacer block 2 by screws.

[0016] A first transmission hinge block 4 and a second transmission hinge block 5 are respectively sleeved on the transmission shaft 22. When the first transmission hinge block 4 and the second transmission hinge block 5 are sleeved on the transmission shaft 22, each has three transmission shaft guide holes 10. Both the first transmission hinge block 4 and the second transmission hinge block 5 extend from the end furthest from the grounding ring 3. The first transmission hinge block 4 has three positioning holes in the end furthest from the grounding ring 3. Two of these positioning holes 41 are symmetrically arranged at the upper and lower ends, respectively, and an extension of the pin 6 is inserted into them to initially define the axial position of the pin 6. There is also a long positioning hole 42 located in the middle, in which... The main body section with the pin 6 inserted is used to cooperate with the first transmission hinge block 4 to achieve precise axial positioning and circumferential fixation of the pin 6. The second transmission hinge block 5 is provided with two slots 51, each of which is fitted with a hinge bolt 7. One end of each hinge bolt 7 is equipped with an anti-loosening fastening component 8, which includes a nut 81, a spring washer 82, and a flat washer 83. The spring washer 82 and the flat washer 83 are sequentially sleeved on the hinge bolt 7, and the nut 81 is screwed onto the end of the hinge bolt 7.
