[0002] Cable protection hardware is a device used to protect cables, usually made of metal materials. Its main function is to protect cables from damage from the external environment, such as mechanical collision, chemical corrosion, electromagnetic interference, etc. Cable protection hardware can be designed into different shapes and sizes according to different application scenarios and needs to adapt to various types of cables. It is usually installed at the starting and ending points of the cable, as well as various key positions along the cable line to protect the cable. The damping spacer in cable protection is a device used to reduce shock and prevent structural vibration. It usually consists of a metal rod and some damping material. It can absorb and disperse energy by connecting it to the structure, thereby reducing the vibration amplitude of the structure.

[0003] In the prior art, when the damping spacer is in use, its connecting ends are fixed on multiple conductors of the cable respectively to keep a distance between the multiple conductors. When installing the damping spacer, it is basically done in the air. When the connecting end of the damping spacer is fixed on the conductor, the connecting part of the damping spacer is first docked on the corresponding conductor, and then the structure of the damping spacer itself is driven by related tools to fix it. However, when the connecting part of the damping spacer is docked on the conductor, since it is done in the air, when the related tools are taken out and used, the staff may not be able to spare the energy to hold the connection between the two, which causes the connecting end of the damping spacer to separate from the conductor, causing inconvenience to the installation of the damping spacer.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 A cable protection hardware for power engineering, including a connecting plate 1, both ends of the connecting plate 1 are fixedly connected with a spacer 2, the four end side walls of the two spacers 2 are fixedly connected with a limit plate 3, and a connecting rod 4 is arranged between the two limit plates 3 located at the same end. The four connecting rods 4 are all located between the two spacers 2. Through the corresponding two limit plates 3, the corresponding connecting rod 4 can quickly find the position between the two spacers 2.

[0022] Specifically, fixing grooves are provided on the side walls of the four connecting rods 4, and the fixing grooves on the side walls of the four connecting rods 4 are threadedly connected with fixing devices. The fixing devices include connecting screws 5 threadedly connected to the fixing grooves on the side walls of the connecting rods 4. The connecting screws 5 pass through the side wall of one of the spacer frames 2, and a connecting nut 6 is passed through and fixedly connected to the side wall of the other spacer frame 2. One end of the connecting screw 5 is threadedly connected to the connecting nut 6.

[0023] Among them, by making different types of connecting rods 4 correspond to the two limit plates 3, the fixing groove on the connecting rod 4 will correspond to the position of the connecting nut 6, and then the corresponding connecting screw 5 will pass through one of the spacer frames 2 and the connecting rod 4 in turn, and finally be threadedly connected to the corresponding connecting nut 6. At this time, the corresponding connecting screw 5 and connecting nut 6 can fix the corresponding connecting rod 4 between the two spacer frames 2.

[0024] Specifically, one end of the four connecting rods 4 is fixedly connected to a first limit frame 7, and the ends of the four first limit frames 7 away from the corresponding connecting rods 4 are fixedly connected to a rotating shaft 8. The side walls of the four rotating shafts 8 are rotatably connected to second limit frames 9. The positions of the four first limit frames 7 correspond to the positions of the four second limit frames 9. The ends of the four second limit frames 9 away from the corresponding rotating shafts 8 are fixedly connected to a limiting device. The limiting device includes a device rod 10 fixedly connected to the end of the second limit frame 9 away from the rotating shaft 8. The position of the device rod 10 corresponds to the position of the connecting rod 4. The corresponding device rod 10 and the second limit frame 9 can be rotated synchronously through the rotating shaft 8. After the second limit frame 9 rotates away from the corresponding first limit frame 7, the wire can be located between the two. Then the device rod 10 is rotated back to the position of the corresponding connecting rod 4, so that the wire can be stuck between the corresponding first limit frame 7 and the second limit frame 9.

[0025] Among them, a sliding plate 11 is slidably connected to the side wall of the device rod 10, a blocking block 13 is fixedly connected to the side wall of the connecting rod 4, the position of the sliding plate 11 corresponds to the position of the blocking block 13, a sliding groove is provided on the side wall of the device rod 10, an operating rod 12 is slidably connected to the groove wall of the sliding groove, and one end of the operating rod 12 is fixedly connected to the side wall of the device rod 10.

[0026] Specifically, after controlling the operating rod 12, the sliding plate 11 can be driven to slide. When the wire is stuck between the corresponding first limit frame 7 and the second limit frame 9, the sliding plate 11 can be moved to the blocking block 13. The blocking block 13 can block the movement of the sliding plate 11, thereby blocking the rotation of the device rod 10, so that the wire will not easily fall out of position.

[0027] Among them, a connecting groove is commonly provided between the device rod 10 and the connecting rod 4, and a fixing screw 14 is threadedly connected in the connecting groove. A through groove is provided on the side wall of the sliding plate 11, and the position of the connecting groove corresponds to the position of the through groove. The fixing screw 14 passes through the position of the through groove. When the sliding plate 11 moves to the blocking block 13, the position of the through groove corresponds to the position of the connecting groove. At this time, a tool can be used to rotate the fixing screw 14 threadably into the connecting rod 4 and the through groove, so as to fix the connecting rod 4 and the corresponding device rod 10.

[0028] In the utility model, through the corresponding two limit plates 3, the corresponding connecting rod 4 can be quickly positioned between the two spacer frames 2. After the connecting rods 4 of different models correspond to the two limit plates 3, the fixing grooves on the connecting rods 4 will correspond to the positions of the connecting nuts 6. Then the corresponding connecting screws 5 will pass through one of the spacer frames 2 and the connecting rod 4 in turn, and finally will be threadedly connected to the corresponding connecting nuts 6. At this time, the corresponding connecting screws 5 and connecting nuts 6 can fix the corresponding connecting rod 4 between the two spacer frames 2.

[0029] The corresponding device rod 10 and the second limit frame 9 can be rotated synchronously through the rotating shaft 8. After the second limit frame 9 rotates out of the corresponding first limit frame 7, the wire can be located between the two. Then the device rod 10 is rotated back to the position of the corresponding connecting rod 4, so that the wire can be stuck between the corresponding first limit frame 7 and the second limit frame 9. After controlling the operating lever 12, the sliding plate 11 can be driven to slide. When the wire is stuck between the corresponding first limit frame 7 and the second limit frame 9, the sliding plate 11 can be moved to the blocking block 13. The blocking block 13 can block the movement of the sliding plate 11, thereby blocking the rotation of the device rod 10, so that the wire will not easily leave the position. When the sliding plate 11 moves to the blocking block 13, the position of the through groove corresponds to the position of the connecting groove. At this time, a tool can be used to thread the fixing screw 14 into the connecting rod 4 and the through groove, thereby fixing the connecting rod 4 and the corresponding device rod 10.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
