[0002] Overhead cable (full name overhead insulated cable) is an overhead conductor equipped with an insulation layer and a protective outer sheath. It is a special cable manufactured using a production process similar to that of cross-linked cables. It is a new way of transmitting electricity between overhead conductors and underground cables. Overhead cables are all single-core. According to their different structures, they can be divided into hard aluminum wire structure, hard-drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure and self-supporting three-core corrugated structure (the wire core can be hard aluminum or hard copper wire), etc. It has the main characteristics of high power supply reliability, good power supply safety, easy installation and maintenance, and reasonable economy. Its main technical parameters include weather resistance, insulation level, inner and outer semi-conductive shielding layers. Overhead cables are widely used in power transmission at home and abroad.

[0003] When installing and fixing existing overhead cables, the conductor fixing device is fixed to the insulating porcelain bottle by using a wire clamp, and then the cable is passed through the conductor fixing device, which includes bolts, gaskets and clamps, and then it is clamped and fixed by tightening the bolts.

[0015] The utility model is further configured such that the outer wall of the telescopic block is arranged in an arc shape.

[0016] By adopting the above technical solution, the telescopic block can fit the outer wall of the cable more closely, thereby achieving a better effect in adjusting the size of the cable.

[0017] The present invention is further configured such that the inner wall of the groove matches the outer wall of the telescopic block.

[0018] By adopting the above technical solution, the telescopic block will move in the groove, limiting the telescopic block, and the friction and resistance are smaller.

[0019] In summary, the present invention has the following beneficial effects:

[0020] The utility model provides a telescopic block and a spring. When the worker is installing the cable, the worker inserts the overhead cable into the fixing frame, and then adjusts the position of the telescopic block by squeezing the spring, so as to achieve adjustment and clamping of cables with different diameters.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] The following describes an embodiment of the present invention based on its overall structure.

[0028] An overhead cable that is easy to fix, such as Figure 1 - Figure 4As shown, it includes a fixing frame 1, a cable 2 and a clamp 13. The ends of both sides of the clamp 13 are fixedly connected to the second fixing frame 14, and the outer wall of the second fixing frame 14 is provided with a circular groove 15. The fixing frame 1 is located at the top of the second fixing frame 14. First, the cable 2 is passed through the fixing frame 1. At this time, the cable 2 contacts the telescopic block 3 on the outer wall of the second fixing frame 14. The telescopic block 3 will squeeze or contract the first spring 7 inside the telescopic block 3 according to the diameter of the cable 2, thereby driving the telescopic block 3 to move, so that the telescopic block 3 fits the outer wall of the cable 2 and clamps the cable 2. Then, the fixing frame 1 is covered on the end of the cable 2. The arc-shaped groove 16 on the outer wall of the fixing frame 1 passes through the protrusion 8 and the cross plate 9. At this time, the fixing frame 1 is aligned with the second fixing frame 14, and the fixing frame 1 is aligned with the second fixing frame 14. A vertical rod 11 is connected between the fixed frames 14, an arc-shaped groove 16 is provided on the outer wall of the fixed frame 1, and an arc surface is provided at the bottom end of the fixed frame 1. A telescopic block 3 is movably provided on the arc surface. A groove 4 is provided inside the fixed frame 1, and a fixed block 5 is installed inside the groove 4. The outer wall of the fixed block 5 is sleeved with a first spring 7. The fixed frame 1 is connected to the second fixed frame 14 through a fixing assembly. Pull the protrusion 8, and the protrusion 8 will drive the second spring 10 to expand and contract. When the protrusion 8 is located above the limiting groove 6 on the outer wall of the fixed frame 1, rotate and release the protrusion 8 so that the protrusion 8 falls into the limiting groove 6, and the protrusion 8 is limited so that the protrusion 8 will not move easily, thereby completing the fixation of the protrusion 8, completing the fixation of the fixed frame 1 and the second fixed frame 14, and thus completing the fixation of the cable 2.

[0029] Please refer to Figure - Figure, the fixing assembly includes a vertical rod 11, and the outer wall of the vertical rod 11 is provided with a second spring 10, the bottom of the vertical rod 11 is fixedly provided with a fixing plate 12, one end of the second spring 10 is fixedly connected to the fixing plate 12, and the outer wall of the vertical rod 11 is provided with a horizontal plate 9. When the fixing frame 1 and the second fixing frame 14 are aligned, the second spring 10 is squeezed by pulling the protrusion 8, thereby driving the vertical rod 11 to move upward, and then the protrusion 8 is rotated and released. The vertical rod 11 will be reset under the action of the elastic force, thereby achieving the fixation of the fixing frame 1 and the second fixing frame 14.

[0030] See also Figure 2 and Figure 4 A limiting groove 6 is provided on the outer wall of the fixing frame 1, and the limiting groove 6 limits the protrusion 8. When the protrusion 8 is located directly above the second fixing frame 14, the protrusion 8 is rotated and released so that the sharp corners at both ends of the protrusion 8 can fall into the limiting groove 6, thereby limiting the protrusion 8 and preventing it from moving.

[0031] See also Figure 3The width of the circular groove 15 is smaller than the horizontal plate 9, and the horizontal plate 9 limits the vertical rod 11. When installing the second fixing frame 14, the fixing components are installed at both ends of the second fixing frame 14. The width of the circular groove 15 is smaller than the horizontal plate 9, so that the horizontal plate 9 will be stuck at the top of the circular groove 15, thereby limiting the vertical rod 11 to ensure that it will not fall.

[0032] See also Figure 2 An empty slot is opened inside the telescopic block 3, and the first spring 7 is located inside the empty slot, and one end of the first spring 7 is fixedly connected to the telescopic block 3, so that the first spring 7 can drive the telescopic block 3 to move when it is extended and retracted. The empty slot ensures that the first spring 7 will not be affected when it is extended and retracted.

[0033] See also Figure 2 The outer wall of the telescopic block 3 is arranged in an arc shape. When the cable 2 is fixed, the arc shape of the outer wall of the telescopic block 3 can make the telescopic block 3 fit the outer wall of the cable 2 more closely, and the effect of adjusting the size of the cable 2 is better.

[0034] See also Figure 2 The inner wall of the groove 4 matches the outer wall of the telescopic block 3. When the telescopic block 3 moves, the outer wall of the telescopic block 3 will move in the groove 4 to limit the telescopic block 3, and the friction and resistance are smaller.

[0035] When the cable 2 is tightened, the worker first inserts the cable 2 into the fixing frame 1. At this time, the cable 2 contacts the telescopic block 3 on the outer wall of the second fixing frame 14. The telescopic block 3 will squeeze or contract the first spring 7 inside the telescopic block 3 according to the diameter of the cable 2, thereby driving the telescopic block 3 to move, so that the telescopic block 3 fits the outer wall of the cable 2 and clamps the cable 2. Then the fixing frame 1 is covered on the end of the cable 2. The arc groove 16 of the outer wall of the fixing frame 1 passes through the protrusion 8 and the cross plate 9. At this time, the fixing frame 1 is aligned with the second fixing frame 14, and the protrusion 8 is pulled. The protrusion 8 will drive the second spring 10 to expand and contract. When the protrusion 8 is above the limiting groove 6 on the outer wall of the fixing frame 1, the protrusion 8 is rotated and released so that the protrusion 8 falls into the limiting groove 6, limiting the protrusion 8 so that the protrusion 8 will not move easily, thereby completing the fixation of the protrusion 8, completing the fixation of the fixing frame 1 and the second fixing frame 14, and thus completing the fixation of the cable 2.
