[0027] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Depend on Figure 1The electric power hardware suspension clamp shown comprises:

[0029] The clamping assembly is used to clamp the power cable 6. The clamping assembly includes a clamping seat, which is detachably connected to the cable 6 through a plurality of U-shaped screws 5. Nuts are threaded at both ends of the screws 5. The nuts are sleeved with a cable 7. The cable 7 is preferably woven with steel wire and can withstand high-strength pulling force.

[0030] The mounting seat is used to suspend the clamping assembly. The mounting seat includes a mounting plate 8. A connecting piece 9 is fixedly connected to the top surface of the mounting plate 8. A cable 7 is arranged to penetrate the mounting plate 8.

[0031] The adjusting unit is used to adjust the height of the cable 6. The adjusting unit includes a driving shaft 10. The driving shaft 10 is arranged to pass through the mounting plate 8. The two ends of the driving shaft 10 are respectively and detachably connected to the mounting plate 8. A reel 11 corresponding to the upper and lower sides of the screw rod 5 is rotatably connected to the middle part of the driving shaft 10. The reel 11 is wound around the cable 7. Regulators are respectively arranged at the two ends of the outer side of the reel 11, and the regulator is fixedly connected to the driving shaft 10.

[0032] Furthermore, the connecting member 9 is a commonly used lifting ring or hook, which is used to fix or connect with other components above the cable 6. It is a prior art and will not be described in detail here.

[0033] A further optimized solution is that the nut includes a screw disk 23, which is threadedly connected to the screw rod 5, a groove is provided on the side of the screw disk 23, the cable 6 is adapted to the groove, the screw disk 23 is wound around the cable 7 through the groove, and an anti-rotation block 24 is fixedly connected to the side of the screw disk 23. The anti-rotation block 24 is a semicircular ring structure, one side of the anti-rotation block 24 is provided with a cavity adapted to the cable 7, and the other side of the anti-rotation block 24 is provided with two through holes, the cable 7 crosses and passes through all the through holes and is wound around the two screw disks 23.

[0034] Furthermore, a plurality of gaskets are provided between the screw disk 23 and the bottom surface of the mounting plate 8 for adjusting the direction of the through holes on the side of the screw disk 23 so that the through holes at both ends of the same screw rod 5 are arranged opposite to each other, which is convenient for cross-winding of the cables 7 .

[0035] To further optimize the solution, Figure 1-2 As shown, the regulator includes a ratchet 12 and a pawl 13 matched with the ratchet 12. The ratchet 12 is sleeved and fixedly connected to the outer side of the driving shaft 10. One end of the pawl 13 is rotatably connected to a rotating shaft 14 through a torsion spring. The torsion spring can pull other components back to their initial positions when they rotate around the center of the spring, generating torque or rotational force. That is, the pawl 13 fixedly connected to one end of the torsion spring can be pressed against the ratchet 12, and the rotating shaft 14 is fixedly connected to the other end of the torsion spring to provide a supporting force. The rotating shaft 14 is fixedly connected to the end face of the reel 11.

[0036] As a further optimization scheme, the ratchet 12 and the pawl 13 on the same side of the reel 11 have the same connection direction, so that the two reels 11 can be driven to reel in the cable 7 at the same time by the rotation of the drive shaft 10 .

[0037] A further optimized solution is that the clamping seat includes an upper seat 1 and a lower seat 2, both ends of the screw rod 5 respectively pass through the upper seat 1 and the lower seat 2 and are screwed together with the nut, the mating surfaces of the upper seat 1 and the lower seat 2 are respectively provided with a receiving groove 4, the inner wall of the receiving groove 4 is attached with a cushion layer 3, and the receiving groove 4 is used for passing the cable 6.

[0038] Furthermore, the cushion layer 3 is a hemp braided layer, which is used to alleviate the friction between the cable 6 and the inner wall of the accommodating groove 4 and reduce wear and tear.

[0039] To further optimize the solution, Figure 3-4 As shown, one end of the drive shaft 10 is fixedly connected to a limit plate 15, and a plurality of limit holes 16 are evenly spaced on the side of the limit plate 15. A limit pin 17 is detachably connected to any of the limit holes 16. A clamping block 18 is fixedly connected to one side of the mounting plate 8, and the top surface of the clamping block 18 is detachably connected to the limit pin 17. By inserting the limit pin 17 into any of the limit holes 16, the drive shaft 10 can be stopped from rotating.

[0040] A further optimization scheme is that a slide groove 19 is provided at the other end of the drive shaft 10, and a slider 20 is slidably connected in the slide groove 19. Stop blocks 21 are fixedly connected at both ends of the slider 20, and a plurality of limit blocks 22 are fixedly connected to the other side of the mounting plate 8. The gap between adjacent limit blocks 22 is adapted to the width of the slider 20. By pulling out the slider 20 and rotating the slider 20 with an existing socket tool, the drive shaft 10 can be driven to rotate. Furthermore, a hexagonal end is provided at the other end of the drive shaft 10, which is convenient for using a wrench to drive the drive shaft 10. This is a prior art and will not be repeated here.

[0041] A further optimization scheme is that the angle between adjacent limit holes 16 is equal to the angle between the gaps between two adjacent limit blocks 22, so that when the limit pin 17 is inserted into any limit hole 16, the push slider 20 can be inserted into the gap between the two limit blocks 22.

[0042] The working process of this embodiment is as follows:

[0043] The utility model is fixedly installed on the fixing frame where the cable 6 is suspended through the connecting piece 9, and then the cable 6 is passed through the accommodating groove 4, and the upper seat 1 and the lower seat 2 are fastened by tightening the nut to keep the cable 6 clamped and prevent the cable 6 from moving in the clamping seat.

[0044] At this time, a sleeve is inserted into the outside of the slider 20 and the sleeve is pulled to cause the drive shaft 10 to rotate. Since the outside of the screw disk 23 is connected to the winding wheel 11 by the cable 7, the drive shaft 10 drives the ratchet 12 fixedly connected thereto to rotate. The rotation of the ratchet 12 pulls the pawl 13 and the winding wheel 11 to rotate, thereby finally driving the cable 7 to be reeled in and the clamping seat is driven upward.

[0045] When the clamping seat moves up to the target position, at this time, the limit pin 17 is inserted into the limit hole 16 close to the top surface of the limit block 22, and the limit pin 17 will be limited and engaged with the top surface of the limit block 22, and then the slider 20 is pushed into the other end of the slide groove 19 and the gap between the two limit blocks 22 to achieve the limit engagement of the two ends of the drive shaft 10, thereby preventing the cable 7 from driving the reel 11 to rotate due to the deadweight of the clamping seat.

[0046] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
