Description

Technical Field

[0001] This utility model relates to the field of auxiliary installation tools for power cables, specifically a seismic-resistant and reinforced power cable terminal fixing accessory. Background Technology

[0002] Power cables generally refer to cables used for transmitting and distributing electrical energy. Power cables are commonly used in urban underground power grids, power plant lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. During the installation of power cables, special fixing accessories are required to secure the power cable terminals to ensure that the power cables do not become loose during use.

[0003] However, current power cable terminal fixing accessories still have some shortcomings. For example, the adjustment steps of existing power cable terminal fixing accessories are relatively cumbersome, which requires workers to spend a long time adjusting the installation length of the fixing accessories, thus interfering with the installation efficiency of workers and resulting in certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structural deficiencies and provide a seismic-resistant and reinforced power cable terminal fixing accessory. Utility Model Content

[0005] The purpose of this utility model is to provide a seismically reinforced power cable terminal fixing accessory to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seismically reinforced power cable terminal fixing accessory, comprising an arc-shaped bearing plate and a fixing seat. First connecting seats are symmetrically fixedly installed at both ends of the arc-shaped bearing plate, and a fixing screw is fixedly connected through the interior of each first connecting seat. A limiting component is attached to the end of the arc-shaped bearing plate. The fixing seat is fixedly installed on the back of the arc-shaped bearing plate, and an adjusting component is rotatably connected inside the fixing seat. A mounting plate is fixedly connected to the end of the adjusting component. Mounting seats are symmetrically fixedly installed at both ends of the mounting plate, and telescopic connecting rods are symmetrically installed on the inner side of the mounting plate.

[0007] Furthermore, the limiting component includes an arc-shaped limiting plate, a second connecting seat, a metal gasket, a fastening nut, and a limiting mechanism. The second connecting seats are symmetrically fixedly installed on both sides of the arc-shaped limiting plate, and the metal gasket is attached to the outer surface of the second connecting seat. The fastening nut is attached to the outer surface of the metal gasket, and the limiting mechanism is fixedly installed on the inner surface of the arc-shaped limiting plate.

[0008] Furthermore, the end of the second connecting seat is fixedly connected to the side of the arc-shaped limiting plate, and the inner surface of the second connecting seat is in contact with the outer surface of the first connecting seat, and the interior of the second connecting seat is movably connected to the outer surface of the fixing screw.

[0009] Furthermore, the limiting mechanism includes a damping telescopic rod, a rubber rigid arc-shaped clamping plate, and a return spring. The extended end of the damping telescopic rod is fixedly connected to the rubber rigid arc-shaped clamping plate, and a return spring is sleeved on the outside of the damping telescopic rod.

[0010] Furthermore, one end of the reset spring is fixedly connected to the outer surface of the rubber rigid arc-shaped clamping plate, and the other end of the reset spring is fixedly connected to the inner surface of the arc-shaped limiting plate. The rubber rigid arc-shaped clamping plate forms an elastic structure with the arc-shaped limiting plate through the reset spring.

[0011] Furthermore, the adjusting assembly includes a threaded cylinder, a threaded extension rod, and a fixing plate, wherein the threaded cylinder is internally threaded with the threaded extension rod, and the end of the threaded extension rod is fixedly connected to the fixing plate.

[0012] Furthermore, the inner surface of the threaded cylinder is threadedly connected to the outer surface of the threaded extension rod, and the end of the threaded cylinder is rotatably connected to the interior of the fixed seat.

[0013] Furthermore, the end of the fixing plate is fixedly connected to the end of the threaded extension rod, and the other end of the fixing plate is fixedly connected to the outer surface of the mounting plate, and the threaded extension rod forms a fixed structure with the mounting plate through the fixing plate.

[0014] This utility model provides a seismically reinforced power cable terminal fixing accessory, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of a threaded extension rod, allows the threaded extension rod to move along the inside of the threaded cylinder when the operator rotates the threaded cylinder inside the fixed base. This achieves the purpose of quickly adjusting the distance between the arc-shaped bearing plate and the mounting plate, thereby avoiding the situation where the operator has to spend a long time adjusting the installation length of the fixed accessories, which interferes with the operator's installation efficiency. Furthermore, the setting of a telescopic connecting rod makes it smoother and more convenient for the operator to adjust the position of the mounting plate through the adjustment component.

[0016] 2. This utility model, through the setting of a damping telescopic rod and a return spring, enables the rubber rigid arc-shaped clamping plate to fit and clamp the power cable terminal when the operator rotates the fastening nut to make the arc-shaped limiting plate gradually approach the arc-shaped bearing plate to fix the power cable terminal. This ensures that the power cable terminal will not loosen during use. At the same time, the damping telescopic rod and the return spring work together to improve the shock resistance of the fixing accessory, thereby ensuring that the power cable is not easily disturbed during use.

A limit assembly 4 is attached to the end of the arc-shaped bearing plate 1. The fixing seat 5 is fixedly installed on the back of the arc-shaped bearing plate 1, and an adjusting assembly 6 is rotatably connected inside the fixing seat 5. The adjusting assembly 6 includes a threaded cylinder 61, a threaded extension rod 62, and a fixing plate 63. The threaded extension rod 62 is threadedly connected inside the threaded cylinder 61, and the inner surface of the threaded cylinder 61 is threadedly connected to the outer surface of the threaded extension rod 62.

The other end of the fixed plate 63 is fixedly connected to the outer surface of the mounting plate 7. The threaded extension rod 62 and the mounting plate 7 form a fixed structure through the fixed plate 63. By setting the threaded extension rod 62 and the mounting plate 7 into a fixed structure, the threaded extension rod 62 and the mounting plate 7 will not become loose when the threaded extension rod 62 moves the mounting plate 7. The end of the adjusting component 6 is fixedly connected to the mounting plate 7, and the two ends of the mounting plate 7 are symmetrically fixedly mounted with mounting seats 8. At the same time, telescopic connecting rods 9 are symmetrically mounted on the inner side of the mounting plate 7.

[0023] like Figures 1-3As shown, first connecting seats 2 are symmetrically fixedly installed at both ends of the arc-shaped support plate 1, and a fixing screw 3 is fixedly connected through the inside of the first connecting seat 2. A limiting component 4 is attached to the end of the arc-shaped support plate 1. The limiting component 4 includes an arc-shaped limiting plate 41, a second connecting seat 42, a metal washer 43, a fastening nut 44, and a limiting mechanism 45. The second connecting seats 42 are symmetrically fixedly installed on both sides of the arc-shaped limiting plate 41, and the ends of the second connecting seats 42 are fixed to the sides of the arc-shaped limiting plate 41. The second connecting seat 42 is connected to the outer surface of the first connecting seat 2, and the interior of the second connecting seat 42 is movably connected to the outer surface of the fixing screw 3. A metal washer 43 is attached to the outer surface of the second connecting seat 42, and a fastening nut 44 is attached to the outer surface of the metal washer 43. At the same time, a limiting mechanism 45 is fixedly installed on the inner surface of the arc-shaped limiting plate 41. The limiting mechanism 45 includes a damping telescopic rod 451, a rubber hard arc-shaped clamping plate 452, and a reset mechanism. A spring 453 is provided, and a rubber rigid arc-shaped clamping plate 452 is fixedly connected to the extended end of the damping telescopic rod 451. A return spring 453 is sleeved on the outside of the damping telescopic rod 451. One end of the return spring 453 is fixedly connected to the outer surface of the rubber rigid arc-shaped clamping plate 452, and the other end of the return spring 453 is fixedly connected to the inner surface of the arc-shaped limiting plate 41. The rubber rigid arc-shaped clamping plate 452, through the return spring 453 and the arc-shaped limiting plate 41, forms an elastic structure. The rubber rigid arc-shaped clamping plate 452 and the arc-shaped limiting plate 41 are configured as elastic structures, so that the rubber rigid arc-shaped clamping plate 452 can fit against the outer surface of the power cable terminal to complete the fixing work. The fixing seat 5 is fixedly installed on the back of the arc-shaped bearing plate 1, and the fixing seat 5 is rotatably connected to the adjusting component 6.

[0024] In summary, this seismically reinforced power cable terminal fixing accessory is first based on... Figures 1 to 3As shown in the diagram, the worker attaches the arc-shaped bearing plate 1 to the outer surface of the power cable terminal, then grasps the arc-shaped limiting plate 41 and passes the second connecting seat 42 through the fixing screw 3 to complete the initial installation of the arc-shaped limiting plate 41. Next, the metal washer 43 is placed on the outer surface of the fixing screw 3 and the fastening nut 44 is rotated to complete the fixing of the arc-shaped limiting plate 41. At this time, through the cooperation of the damping telescopic rod 451 and the return spring 453, the rubber rigid arc-shaped clamping plate 452 automatically adheres to the outer surface of the power cable terminal to complete the fixing work, thus completing the initial installation of the fixing accessory. Then, the worker grasps the threaded cylinder 61 and drives it to rotate inside the fixing seat 5. At this time, through the connection of the telescopic connecting rod 9, the threaded extension rod 62 moves outward along the inside of the threaded cylinder 61, thereby causing the fixing plate 63 to drive the mounting plate 7 to move towards the installation point. When the mounting plate 7 is in contact with the installation point, the bolt is rotated to complete the fixing of the mounting seat 8, thus completing the overall quick installation of the power cable terminal.
