The limit block 45 can ensure the stability of the sliding connection relationship between the square rod 44 and the reinforcing bolt 42, thereby avoiding the phenomenon of structural falling off. A pre-tightening clamp 21 is also provided inside the terminal 2, and a first slider 211 is fixedly installed on the side of the pre-tightening clamp 21. A pre-tightening spring 22 is fixedly installed on the side of the first slider 211. The end of the pre-tightening spring 22 away from the first slider 211 is fixedly connected to the terminal 2, and a sliding groove 23 for limiting the sliding range of the second slider 431 and the first slider 211 is also provided on the terminal 2. The establishment of the pre-tightening spring 22 and the pre-tightening clamp 21 allows the user to place the grounding cable on the terminal 2 first, thereby avoiding the cable slipping phenomenon when adjusting the position of the reinforcement plate 43 later, so that the overall structural operation is more practical.

[0027] The terminal 2 is also provided with a transmission assembly 5, which includes a bar seat 53 that is slidably connected to the terminal 2, a ring seat 54 that is fixedly mounted on the bar seat 53, a friction plate 55 that is rotatably mounted on the ring seat 54, an end face gear 56 that is fixedly mounted on the friction plate 55, and a transmission gear 57 that is meshingly connected to the side of the end face gear 56. The transmission gear 57 is also rotatably arranged inside the ring seat 54, and a connecting shaft 58 is fixedly mounted on the transmission gear 57, a first bevel gear 59 is fixedly mounted on the end face of the connecting shaft 58, and a second bevel gear 510 is meshingly connected to the side of the first bevel gear 59, and a transmission shaft 511 is fixedly mounted on the second bevel gear 510, and the second bevel gear 510 is rotated by the transmission shaft 511.

The two ends of the fixed rod 52 are fixedly connected to the push plate 51 and the bar seat 53 respectively, and the fixed rod 52 is also slidably connected to the U-shaped iron plate 1. The annular seat 54 is located in the internal cavity of the terminal 2, and the annular seat 54 does not contact the square rod 44. Such designs can avoid the annular seat 54 from interfering with other structures inside the device, thereby ensuring that other structures can operate stably and reasonably, thereby achieving the purpose of pre-establishing such structures. The friction plate 55 is a ring-shaped structure design, and the side of the friction plate 55 close to the connector 41 is provided with friction grooves for enhancing friction. Both ends of the transmission shaft 511 are provided with a second bevel gear 510 meshing with the first bevel gear 59.

[0028] A limit assembly 6 is provided on the push plate 51. The limit assembly 6 includes a knob 61, a fixed cylinder 62, an insert 63, a central shaft 64, a connecting rod 65, an auxiliary protrusion 66 and a return spring 67. The knob 61 is fixedly mounted on the end face of the central shaft 64. The fixed cylinder 62 is fixedly mounted on the side of the push plate 51 close to the U-shaped iron plate 1. The insert 63 is slidably arranged on the fixed cylinder 62. The central shaft 64 is rotatably arranged on the push plate 51. The two ends of the connecting rod 65 are movably connected to the fixed cylinder 62 and the insert 63 respectively. The auxiliary protrusion 66 is slidably arranged. It is on the fixed cylinder 62 and fixedly connected to the insert block 63. The two ends of the return spring 67 are respectively fixedly connected to the auxiliary protrusion 66 and the fixed cylinder 62. A circular hole 11 for plugging with the fixed cylinder 62 is opened on the side of the U-shaped iron plate 1 close to the push plate 51. It cooperates with the insert block 63 to limit the position of the push plate 51 to avoid the friction plate 55 from disengaging from the transmission in time when the friction plate 55 and other structures are transmitting, so as to ensure the transmission performance of the entire transmission assembly 5 and further improve the utilization efficiency of the overall structure.

[0029] Working principle: Use a U-shaped iron plate 1 and two webs 3 to form a bracket, weld the terminal 2 suitable for the type and number of grounding cables on the U-shaped iron plate 1 to form a centralized grounding device, fix the grounding device to the structure near the equipment by welding, and lead the grounding cables of nearby equipment to the device for fixation.

[0030] When actually connecting the grounding cable to the terminal 2, the pre-tightening clamp 21 slides inside the slide groove 23 provided on the terminal 2 through the first slider 211 fixed thereto, and the first slider 211 is further connected to the terminal 2 through the pre-tightening spring 22. Therefore, the grounding cable can be placed between the pre-tightening clamp 21 and the terminal 2, and the position of the grounding cable is initially restricted by the pre-tightening spring 22. Then, the hexagonal wrench is inserted into the connector 41 to drive the connector 41 to rotate. The square rod 44 on the head 41 is in a sliding connection with the reinforcing bolt 42. Because the reinforcing bolt 42 is in a threaded connection with the terminal 2, the reinforcing bolt 42 is screwed out of the terminal 2 and moves toward the pre-tightening clamp 21 as the connecting head 41 rotates. The reinforcing plate 43, which is slidably connected to the terminal 2 through the second slider 431, is in a rotating connection with the reinforcing bolt 42, which will push the reinforcing plate 43 to squeeze the pre-tightening clamp 21, thereby tightly clamping the grounding cable between the pre-tightening clamp 21 and the terminal 2.

[0031] When it is necessary to connect all the terminals 2 to the grounding cables at the same time, first turn the knob 61, and the central shaft 64 fixedly connected to the knob 61 rotates synchronously. Under the action of the connecting rod 65 movably connected to the central shaft 64 and the plug block 63 at both ends, the plug block 63 is pulled to slide toward the inside of the fixed cylinder 62. At this time, the push plate 51 can be pushed so that the central shaft 64 fixed on the push plate 51 is inserted into the circular hole 11 on the U-shaped iron plate 1. Then release the knob 61, and under the action of the return spring 67 fixedly connected to the auxiliary protrusion 66 and the fixed cylinder 62 at both ends, and the auxiliary protrusion 66 is fixed on the plug block 63, the plug block 63 is pushed to be inserted into the inside of the U-shaped iron plate 1, limiting the position of the push plate 51 and other structures. At the same time, because the two ends of the fixing rod 52 are fixedly connected to the push plate 51 and the bar seat 53 respectively, the sliding of the push plate 51 will push the bar seat 53 to slide together, and the annular seat 54 fixedly connected to the bar seat 53 slides synchronously until The friction plate 55 set on the annular seat 54 is rotated to contact the connecting head 41. Because the side of the friction plate 55 is provided with friction grooves for enhancing friction, a certain amount of friction will be generated after contacting the connecting head 41, so that the friction plate 55 will rotate as the connecting head 41 rotates, and the end face gear 56 fixed on the friction plate 55 also rotates accordingly. The end face gear 56 is meshed with the transmission gear 57. The connecting shaft 58 fixed on the transmission gear 57 is fixedly connected to the first bevel gear 59, and the first bevel gear 59 is meshed with the second bevel gear 510. The second bevel gear 510 is provided on both ends of the transmission shaft 511 set inside the bar seat 53. Therefore, under the transmission of such structure, the connecting heads 41 inside the multiple terminal posts 2 will rotate synchronously, thereby driving the multiple reinforcing bolts 42 to synchronously unscrew the terminal posts 2 and push the reinforcing plate 43 to strengthen the tightness of the connection between the terminal posts 2 and the grounding cable.
