[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0022] like Figures 1 to 6 As shown, it shows an anti-loosening high-voltage wire clamping power hardware in one embodiment of the present disclosure, including a cable end 1 and a cable end 2, the cable end 1 and the cable end 2 are connected through the power hardware, and also includes a fixed base 3, a stretching clamping mechanism, a U-bolt 5, and a wedge-shaped groove 6. The fixed base 3 is fixedly connected with a sliding connecting plate 4, the sliding connecting plate 4 is arranged in the center of the fixed base 3, and the stretching clamping mechanism is arranged on the sliding connecting plate 4. The cable end 1 and the cable end 2 can be detachably fixed on the stretching clamping mechanism, and the stretching clamping mechanism is used to tighten the cable end 1 and the line The cable end 2 is stretched and clamped, two U-bolts 5 are provided, and the U-bolts 5 are detachably arranged on both sides of the sliding connecting plate 4, and the U-bolts 5 are used to press the cable end 1 or the cable end 2. Two wedge-shaped grooves 6 are provided, and the two wedge-shaped grooves 6 are respectively arranged on the side of the two U-shaped bolts 5 away from the sliding connecting plate 4. Wedge core mechanisms are detachably arranged in the two wedge-shaped grooves 6, and the two wedge core mechanisms are detachably connected to the cable end 1 and the cable end 2, respectively, and the wedge core mechanism is used to fix the cable end 1 or the cable end 2 in the wedge-shaped groove 6.
[0023] like Figures 1 to 3As shown, the sliding connection plate 4 is arranged on one side of the fixed base 3, and the stretching clamping mechanism includes a tensioning seat 7, a fixing plate 8, a sliding seat 9 and a segmented clamping member. The tensioning seat 7 is fixedly installed in the center of the sliding connection plate 4, and the fixing plate 8 and the tensioning seat 7 are detachably connected by bolts. The cable end 1 and the cable end 2 pass through between the fixing plate 8 and the tensioning seat 7. Two sliding seats 9 are provided, and the two sliding seats 9 are respectively slidably arranged on both sides of the tensioning seat 7 on the sliding connection plate 4. The sliding seat 9 is detachably provided with a segmented clamping member, which is used to tighten and fix the cable end 1 and the cable end 2. The sliding seat 9 can slide on the sliding connection plate 4. , after the cable end 1 and the cable end 2 are respectively passed through between the fixing plate 8 and the tensioning seat 7, they are fixed on the sliding seat 9. When the fixing plate 8 is pressed toward the tensioning seat 7, the two sliding seats are pushed to both sides by the pushing rod 13, so that the two sliding seats respectively pull the cable end 1 and the cable end 2 to slide, and the cables are tightened. When the fixing plate 8 and the tensioning seat 7 clamp the cable end 1 and the cable end 2, the two sliding seats can also have a pulling effect on the two cables to further prevent the cables from loosening. When the cables are loose, the cables need to pull the sliding seats to slide, and the sliding seats will support the fixing plate 8 through the pushing rod 13 to prevent the cables from sliding and loosening.
[0024] like Figures 1 to 4 As shown, the segmented clamping member includes a clamping plate 10, a clamping plate 2 11 and a clamping plate 3 12. The clamping plate 10 is detachably connected to the sliding seat 9 by bolts. The cable end 1 or the cable end 2 passes between the clamping plate 10 and the sliding seat 9. The clamping plate 2 11 is detachably connected to the sliding seat 9 by bolts. The cable end 1 or the cable end 2 passes between the clamping plate 2 11 and the sliding seat 9. The clamping plate 10 and the clamping plate 2 11 are respectively arranged on both sides of the sliding seat 9. The plate three 12 is detachably connected to the sliding seat 9 through a screw rod, and the clamping plate three 12 is arranged between the clamping plate one 10 and the clamping plate two 11. The clamping plate three 12 is arranged on the side of the clamping plate one 10 and the clamping plate two 11 away from the sliding seat 9. The clamping plate one 10 and the clamping plate two 11 are both arranged in a trapezoidal shape. The clamping plate one 10 and the clamping plate two 11 are arranged opposite to each other. When the long side of the clamping plate one 10 is pressed against the cable end one 1, the short side of the clamping plate one 10 contacts the cable end two 2, so as to Figure 3 For example, in Figure 3The clamping plate 2 11 on the left side sliding seat 9 clamps and fixes the cable end 2 2, and at the same time, the short side of the clamping plate 2 11 contacts the cable end 1 to prevent the bolt on the clamping plate 2 11 from being subjected to a large tilting force. The clamping plate 2 11 on the right side sliding block clamps and fixes the cable end 1. At this time, the bolt on the fixed plate 8 is rotated, and the fixed plate 8 gradually clamps the cable, and the two sliding blocks are pushed by the push rod 13. The sliding block on the left side pulls the cable end 2 2 to slide, and the cable end 1 slides on it, and the sliding block on the right side pulls the cable end 1 to slide. The cable end 2 slides on it, and when the fixing plate 8 and the tensioning seat 7 clamp the cable end 1 and the cable end 2, the clamping plate 10 and the clamping plate 2 11 on the two sliding blocks can be fixed by bolts to achieve the clamping and fixing of the two cables. Then, by fixing the clamping plate 3 12, the clamping plate 3 12 will completely clamp the clamping plate 10 and the clamping plate 2 11 to avoid the unbalanced force between the clamping plate 10 and the clamping plate 2 11 and causing tilting. The area of the clamping plate 3 12 can also be increased to make its clamping effect on the clamping plate 10 and the clamping plate 2 11 better.
[0025] Push rods 13 are rotatably connected to both sides of the fixing plate 8 . When the fixing plate 8 moves toward the tensioning seat 7 , the push rods 13 can push the sliding seat 9 in a direction away from the fixing plate 8 .
[0026] like Figure 1 and Figure 6 As shown, two support blocks 14 are fixedly provided on the fixed base 3, and two U-bolts 5 are respectively sleeved on the two support blocks 14. The cable end 1 or the cable end 2 passes through the U-bolt 5 and the support block 14. The cable end 1 and the cable end 2 are squeezed by the U-bolt 5 and the support block 14, so that the cable end 1 and the cable end 2 are axially aligned with the cable end 1 and the cable end 2. The fixed base 3 can remain parallel to the cable formed by connecting the cable end 1 and the cable end 2. Compared with most of the existing power clamping hardware, after the two cables are connected, due to the traction force of the cables, the power hardware will deflect and tilt, so that the cable at the clamping connection will bend, which is easier to damage.
[0027] like Figures 5 to 6 As shown, the cable end 1 and the cable end 2 are detachably connected to the stretching clamping mechanism on both sides of the sliding connecting plate 4, and the cable end 1 is arranged on the side close to the fixed base 3 in the stretching clamping mechanism. The cable end 1 and the cable end 2 are axially aligned in the parts of the two wedge core mechanisms, and the centers of the two wedge grooves 6 are aligned, so that the cable end 1 and the cable end 2 can also remain aligned.
[0028] like Figures 5 to 6As shown, the wedge-shaped groove 6 is composed of two corner blocks 15 arranged opposite to each other, the inclined surfaces of the two corner blocks 15 face the sliding connecting plate 4, the U-bolt 5 and the center of the support block 14 are aligned with the wedge-shaped groove 6, the wedge core mechanism includes a wedge block 16 and a clamping clamp 17, two wedge blocks 16 are provided, the two wedge blocks 16 are sleeved on the cable end 1 or the cable end 2, the wedge block 16 extends into the wedge-shaped groove 6, and the clamping clamp 17 is detachably sleeved on the cable end 1 or the cable end 2 , the clamping clamp 17 contacts with the wedge block 16. Taking the cable end 1 as an example, after the cable end 1 passes through the wedge groove 6, the two wedge blocks 16 wrap the cable end 1 and extend into the wedge groove 6, and then the clamping clamp 17 is fixed on the cable end 1. When the cable end is pulled, the clamping clamp 17 pushes the wedge block 16 to extend into the wedge groove 6, and the wedge block 16 contacts the corner block 15 and gradually clamps the cable end 1, making it more difficult to slide out of the wedge groove 6.
[0029] In this example, the cable end 1 and the cable end 2 are passed through the wedge groove 6 in two directions respectively, and then through the U-bolt 5, and passed between the fixing plate 8 and the tensioning seat 7, and then fixed on the sliding seat 9. When the fixing plate 8 is fixed, the fixing plate 8 pushes the two sliding seats through the pushing rod 13 to drive the cable end 1 and the cable end 2 to slide respectively. After the fixing plate 8 clamps the cable end 1 and the cable end 2, the clamping plate 10, the clamping plate 2 11 and the clamping plate 3 12 on the two sliding seats are fixed by the corresponding bolts, and then the U-bolt 5 is fixed. The cable end 1 or the cable end 2 is clamped and fixed with the support block 14 so that it is aligned with the wedge-shaped groove 6. After the cable end 1 or the cable end 2 passes through the wedge-shaped groove 6, the two wedge blocks 16 are wrapped around the cable end 1 or the cable end 2 and then extended into the wedge-shaped groove 6. Then, the clamping clamp 17 is fixed on the cable end 1 or the cable end 2. When the cable end is pulled, the clamping clamp 17 pushes the wedge block 16 to extend into the wedge-shaped groove 6. The wedge block 16 contacts the corner block 15 and gradually clamps the cable end 1 or the cable end 2, thereby fixing the cable end 1 and the cable end 2 again to prevent loosening.
[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
