Description

Technical Field

[0001] This application belongs to the field of cable fixing technology, and in particular relates to a power fitting for fixing cables. Background Technology

[0002] Cable fixing refers to the operation of using specialized power fittings to stably install cables (such as conductors, lightning protection wires, guy wires, etc.) on power facilities such as poles and insulator strings to prevent cables from shifting, shaking, or falling off, while also transmitting cable loads. When it is necessary to suspend conductors on straight poles (using suspension clamps), fix the ends of conductors on corner / terminal poles and bear tension (using tension clamps), adjust or fix pole guy wires (using UT clamps), and fix the ends of steel strands (using wire clips) in overhead power lines, various types of cable fixing power fittings will be used accordingly.

[0003] The existing utility model with authorization announcement number CN221428451U discloses an electrical fitting for fixing cables. A clamping base covers the surface of the cable body and is fixed by two sets of fixing bolts. The distance between the clamping plate and the clamping base can be adjusted to accommodate cables of different thicknesses. When the position of the cable body needs to be adjusted, the clamping plate is held and moved laterally on the surface of the fixing base. After the position of the clamping plate is adjusted, the nut is tightened to complete the position adjustment of the cable body and the clamp, adapting to different installation scenarios. The clamping plate and the clamping base are locked together by two sets of fixing bolts to ensure the stability of the clamping plate and the clamping base when holding the cable body, preventing the cable body from loosening. The opening on the lower fixing wing is U-shaped, allowing the fixing bolts to be removed from the lower fixing wing after the clamping base is disassembled.

[0004] While the above technical solution can be adapted to cables of different thicknesses, it requires additional tools to clamp or release the cable, lacking a convenient clamping structure for quick cable placement, making cable fixing or disassembly inconvenient.

[0005] To address this issue, we propose a power fitting for cable fixing. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that the existing technology lacks a convenient clamping structure that can quickly clamp and place cables, which makes it inconvenient to fix or disassemble cables. Therefore, this utility model proposes an electrical fitting for fixing cables.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A power fitting for cable fixing includes an upper arc-shaped frame, a lower arc-shaped frame below the upper arc-shaped frame, a support rod fixedly connected to the inner wall of the lower arc-shaped frame, an adjustment box fixedly connected to the front of the lower arc-shaped frame, an adjustment block and a limit rod slidably connected inside the adjustment box, a hand-tightening limit bolt rotatably connected to the inner wall of the adjustment box, two guide rods slidably connected inside both the upper and lower arc-shaped frames, arc-shaped clamps provided inside both the upper and lower arc-shaped frames, connecting plates provided on the outer sides of both the upper and lower arc-shaped frames, a return spring sleeved on the outer surface of each guide rod, a fixing rod fixedly connected to the front of the upper arc-shaped frame, and a limit locking block rotatably connected to the outer surface of the fixing rod.

[0009] Preferably, the inner wall of the upper arc-shaped frame is rotatably connected to the outer surface of the support rod; the outer surface of the hand-tightening limiting bolt is threadedly connected to the inner wall of the adjusting block; the front of the adjusting block is fixedly connected to the end of the limiting rod near the adjusting block; the end of each guide rod near the arc-shaped clamp is fixedly connected to the outer surface of the arc-shaped clamp; the end of each guide rod near the connecting plate is fixedly connected to the outer surface of the connecting plate; the two ends of the two return springs are respectively fixedly connected to the inner wall of the upper arc-shaped frame and the outer surface of one of the arc-shaped clamps; the two ends of the other two return springs are respectively fixedly connected to the inner wall of the lower arc-shaped frame and the outer surface of the other arc-shaped clamp; the interior of the limiting lock block is engaged with the outer surface of the limiting rod; a support plate is fixedly connected to the right side of the upper arc-shaped frame; and a hanging plate is fixedly connected to the upper surface of the support plate.

[0010] Preferably, an anti-slip sleeve is fixedly connected to the outer surface of the support plate, and a plurality of identical anti-slip protrusions are fixedly connected to the outer surface of the anti-slip sleeve.

[0011] Preferably, a first mounting plate is fixedly connected to both sides of the hanging plate, and each first mounting plate has several identical first mounting holes on its upper surface.

[0012] Preferably, a second mounting plate is fixedly connected to both the front and back of the hanging plate, and a second mounting hole is provided on the front of each second mounting plate.

[0013] Preferably, the outer surface of the hand-tightening limiting bolt is fixedly connected to two first anti-slip pads, and each first anti-slip pad has several identical first anti-slip grooves on its outer surface.

[0014] Preferably, limit sliders are fixedly connected to both sides of the adjustment block, and the outer surface of each limit slider is slidably connected to the inside of the adjustment box.

[0015] Preferably, a second anti-slip pad is fixedly connected to the inner wall of each of the arc-shaped clips, and a plurality of identical second anti-slip grooves are formed on the inner wall of each second anti-slip pad.

[0016] In summary, the technical effects and advantages of this application are as follows:

[0017] Through the coordinated operation of the upper and lower arc-shaped frames, support rod, guide rod, arc-shaped clamp, connecting plate, return spring, adjustment box, adjustment block, hand-tightened limit bolt, limit rod, fixing rod, and limit lock block, the upper and lower arc-shaped frames can wrap the cable after rotating relative to the support rod. Then, under the rebound of the return spring, the two arc-shaped clamps can firmly clamp cables of different sizes. During the clamping of the cable, the limit lock block can engage with the limit rod after rotating around the fixing rod. Afterwards, hand-tightening the limit bolt will allow the adjustment block, which is threaded to the hand-tightened limit bolt, to slide up and down along the inside of the adjustment box, thereby increasing the degree to which the limit rod is locked or loosened. This greatly improves the convenience of cable fixing and avoids the problem of inconvenient cable fixing or disassembly due to the lack of a convenient clamping structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 A power fitting for cable fixing includes an upper arc frame 1, a lower arc frame 2 below the upper arc frame 1, a support rod 3 fixedly connected to the inner wall of the lower arc frame 2, and the inner wall of the upper arc frame 1 rotatably connected to the outer surface of the support rod 3. A support plate 14 is fixedly connected to the right side of the upper arc frame 1, and a hanging plate 15 is fixedly connected to the upper surface of the support plate 14. By setting the support plate 14, it is convenient to connect the upper arc frame 1 and the hanging plate 15. By setting the hanging plate 15, it is convenient to cooperate with other assembly structures to connect the entire fitting to the tower, thereby initially fixing the position of the entire fitting.

[0026] An adjustment box 8 is fixedly connected to the front of the lower arc frame 2. An adjustment block 9 and a limit rod 11 are slidably connected inside the adjustment box 8. An anti-slip sleeve 16 is fixedly connected to the outer surface of the support plate 14. Several identical anti-slip protrusions 17 are fixedly connected to the outer surface of the anti-slip sleeve 16. By setting the anti-slip protrusions 17, the anti-slip properties of the outer surface of the anti-slip sleeve 16 can be increased. By setting the anti-slip sleeve 16 and the anti-slip protrusions 17, the anti-slip properties of the outer surface of the support plate 14 can be increased together.

[0027] The inner wall of the adjusting box 8 is rotatably connected with a hand-tightening limit bolt 10. The outer surface of the hand-tightening limit bolt 10 is threadedly connected to the inner wall of the adjusting block 9. The front of the adjusting block 9 is fixedly connected to the end of the limit rod 11 near the adjusting block 9. The bottom of the hand-tightening limit bolt 10 has a hand-tightening plate for easy hand-tightening, and it has a limit ring to prevent the hand-tightening limit bolt 10 from slipping out of the adjusting box 8. It can prevent it from detaching from the adjusting box 8 while rotating. The interior of the upper arc frame 1 and the interior of the lower arc frame 2 are slidably connected with two guide rods 4. The two sides of the hanging plate 15 are fixedly connected with first mounting plates 18. The upper surface of each first mounting plate 18 is provided with several identical first mounting holes 19. By setting the first mounting holes 19, the first mounting plate 18 can be connected to the horizontal structure on the tower with the external vertical bolt structure, thereby initially assembling the entire hardware.

[0028] Both the interior of the upper arc frame 1 and the interior of the lower arc frame 2 are equipped with arc clamps 5. The end of each guide rod 4 near the arc clamp 5 is fixedly connected to the outer surface of the arc clamp 5. Both the outer side of the upper arc frame 1 and the outer side of the lower arc frame 2 are equipped with connecting plates 6. The end of each guide rod 4 near the connecting plate 6 is fixedly connected to the outer surface of the connecting plate 6. The front and back of the hanging plate 15 are fixedly connected with second mounting plates 20. Each second mounting plate 20 has a second mounting hole 21 on its front. By setting the second mounting hole 21, the second mounting plate 20 can be connected to the vertical structure on the tower with the external horizontal bolt structure, thereby increasing the orientation and posture of the entire hardware.

[0029] Each guide rod 4 has a return spring 7 fitted on its outer surface. The two ends of two return springs 7 are fixedly connected to the inner wall of the upper arc frame 1 and the outer surface of one of the arc clamps 5, respectively. The two ends of the other two return springs 7 are fixedly connected to the inner wall of the lower arc frame 2 and the outer surface of the other arc clamp 5, respectively. Two first anti-slip pads 25 are fixedly connected to the outer surface of the hand-tightening limit bolt 10. Each first anti-slip pad 25 has several identical first anti-slip grooves 26 on its outer surface. By setting the first anti-slip grooves 26, the anti-slip properties of the outer surface of the first anti-slip pads 25 can be increased. By setting the first anti-slip pads 25 and the first anti-slip grooves 26, the anti-slip properties of the outer surface of the hand-tightening limit bolt 10 can be increased together.

[0030] A fixed rod 12 is fixedly connected to the front of the upper arc frame 1. Limiting sliders 24 are fixedly connected to both sides of the adjusting block 9. The outer surface of each limiting slider 24 is slidably connected to the inside of the adjusting box 8. By setting the limiting sliders 24, the adjusting block 9 can slide vertically inside the adjusting box 8, thereby increasing the directional and stable vertical sliding of the adjusting block 9 inside the adjusting box 8.

[0031] The outer surface of the fixed rod 12 is rotatably connected to the limiting lock block 13. The inside of the limiting lock block 13 is engaged with the outer surface of the limiting rod 11. The inner wall of each arc-shaped clamp 5 is fixedly connected with a second anti-slip pad 22. The inner wall of each second anti-slip pad 22 is provided with several identical second anti-slip grooves 23. By setting the second anti-slip grooves 23, the anti-slip properties of the inner wall of the second anti-slip pad 22 can be increased. By setting the second anti-slip pads 22 and the second anti-slip grooves 23, the anti-slip properties of the inner wall of the arc-shaped clamp 5 can be increased together.

[0032] The working principle of this utility model is as follows: When using this power fitting, the fitting is first fixed as a whole by means of the hanging plate 15. The first mounting plates 18 on both sides of the hanging plate 15 can be used with external vertical bolts to pass through the first mounting holes 19 and connect with the horizontal structure of the tower. The second mounting plates 20 on the front and back of the hanging plate 15 can be connected with the vertical structure of the tower by means of the second mounting holes 21 and external horizontal bolts. The anti-slip sleeves 16 and anti-slip protrusions 17 on the outer surface of the support plate 14 enhance the assembly stability and determine the installation position of the fitting.

[0033] Next, the cable is placed and initially clamped. The upper arc frame 1 can rotate and open around the support rod 3 on the inner wall of the lower arc frame 2. After the cable is placed between the upper arc frame 1 and the lower arc frame 2, the guide rod 4 inside the upper arc frame 1 and the lower arc frame 2 will push the arc clamp 5 under the rebound action of the return spring 7. The second anti-slip pad 22 and the second anti-slip groove 23 on the inner wall of the arc clamp 5 can increase the friction with the cable, realizing the initial clamping of the cable. The connecting plate 6 connected to the guide rod 4 can prevent the guide rod 4 from slipping out of the arc frame.

[0034] Finally, after locking the cable and making subsequent adjustments, rotate the limiting locking block 13 on the outer surface of the fixing rod 12 on the front of the upper arc frame 1 to engage with the limiting rod 11 inside the adjusting box 8 on the front of the lower arc frame 2. Then, rotate the hand-tightening limiting bolt 10 on the inner wall of the adjusting box 8. The first anti-slip pad 25 and the first anti-slip groove 26 on the outer surface of the hand-tightening limiting bolt 10 facilitate the application of force. Under the directional sliding action of the limiting sliders 24 on both sides of the adjusting block 9, the adjusting block 9 will drive the limiting rod 11 to move downward along the adjusting box 8. Adjust the tightness of the engagement between the limiting locking block 13 and the limiting rod 11 to complete the cable fixing. When disassembling the cable, rotate the hand-tightening limiting bolt 10 in the opposite direction to gradually loosen the limiting rod 11 by rotating the limiting locking block 13. Then, rotate the limiting locking block 13 to disengage from the limiting rod 11. Open the upper arc frame 1 to remove the cable. The design of the entire power fitting for cable fixing effectively solves the problem of inconvenient cable fixing or disassembly due to the lack of a convenient clamping structure for quick cable clamping.
