[0031] To further explain, a section of external thread is correspondingly provided on the outside of the lower end of the rotating shaft 6486, and the rotating shaft 6486 can be threadedly connected with the middle part of the lower end of the shell 6481 through the external thread, ensuring that the rotating shaft 6486 can be locked with the rotating shaft 6486, ensuring the stability of the subsequent expansion state of the opening and closing block 6488; the connecting arm 6487 and the opening and closing block 6488 are symmetrically arranged on the left and right sides of the upper end of the movable plate 6485, and the lower end of the opening and closing block 6488 is rotatably connected to the inside of the shell 6481, ensuring that the opening and closing block 6488 can be lifted with the connecting arm 6487 to achieve stable expansion or collection transmission.

[0032] Here’s how it works:

[0033] When the present wire plug is to be used, the plug body 1, the rubber sleeve 2 and the incision line 5 provided on the outside of the sealing ring 3 can be used to perform cutting activities in sequence. In this way, the plug body 1, the rubber sleeve 2 and the sealing ring 3 can be opened to insert the cable until the plug body 1 and the rubber sleeve 2 wrap the cable to provide cable wrapping protection. Then, the wrapped plug body 1 can be installed inside the wire hole outside the meter box, and the rubber sleeve 2 can be matched with the sealing ring 3 provided on the outside to dock with the wire hole combination, so as to assist in achieving efficient protection and blocking of the cable and improve the stability of cable installation.

[0034] In order to further improve the installation sealing performance, so that the plug body 1 can be tightly attached to the wire hole and reduce the occurrence of air leakage, a connecting and fastening device 6 is also provided on the left and right sides of the upper end of the plug body 1, that is, the metal strip 61 is transversely fastened to the left and right sides of the upper end of the plug body 1 through the connecting column 62 and the fastening head 63 in advance, and then two round holes are opened to the right outside the meter box to correspond to the subsequent locking position. After the drilling is completed, the rubber sleeve 2 can be passed through the wire hole so that the plug body 1 can be pre-attached to one side of the wire hole. In this way, the sleeve 642 provided on the other side of the metal strip 61 will penetrate into the inside of the round hole opened. At this time, The screw rod 643 provided inside the sleeve 642 is rotated to rotate the screw rod 643, thereby realizing transmission of the outer threaded connection with the inner tube 644, so that the inner tube 644 moves downward, and the outer tube 645 connected to the outer end of the inner tube 644 can realize synchronous movement. In this way, the outer tube 645 can cooperate with the limiting grooves 646 provided on the left and right sides and the limiting ring 647 provided at the lower end of the sleeve 642 to realize stable downward movement, so as to push the opening and closing structure 648 provided at the bottom out of the sleeve 642, so that the opening and closing structure 648 moves out to a suitable unfolding and locking position, thereby conveniently performing transmission locking, and improving the convenience of subsequent connection and locking;

[0035] After the opening and closing structure 648 is moved out, the rotating shaft 6486 provided in the middle part of the lower end of the shell body 6481 can be pushed up to make the movable plate 6485 connected to the upper end of the rotating shaft 6486 move up, and the movable plate 6485 can be moved up, which can not only push up the plug-in shaft 6483 vertically plugged in the middle part to perform the moving and guiding activities, but also push up the connecting arms 6487 on the left and right sides of the upper end that are rotatably connected, so that the connecting arms 6487 on both sides can be driven correspondingly to the L-shaped opening and closing blocks 6488 to push the opening and closing blocks 6488 through the openings on the left and right sides of the upper end of the shell body 6481 to perform the outward movement and expansion activities. When the opening and closing blocks 6488 on both sides complete the expansion activities synchronously, the rotating shaft 6486 can be rotated accordingly to make the rotating shaft 6486 cooperate with the outer The external thread is locked with the middle part of the lower end of the shell 6481, so that the opening and closing blocks 6488 unfolded on both sides can maintain a stable state. In this way, the opening and closing blocks 6488 unfolded on both sides can be stably abutted against the two ends of the circular hole opened on the outside of the meter box, so as to perform compression and reinforcement to improve the sealing effect. At the same time, the screw 643 can be rotated in the opposite direction to pull up the inner tube 644 and the outer tube 645. In this way, the shell 6481 as a whole can be slightly moved upward, so that the opening and closing blocks 6488 unfolded on both sides can be stably abutted against the outside of the meter box, so as to significantly improve the sealing effect of the plug body 1 against one side of the wire hole, improve the overall sealing performance, and reduce the entry of dust or impurities, thereby achieving the advantages of auxiliary connection and tightening of the wire plug and improving the sealing performance.

[0036] In addition, when the movable plate 6485 pushes the plug-in shaft 6483 upward, the compression spring 6484 provided on the outside of the plug-in shaft 6483 will be compressed simultaneously. Therefore, when the unlocking activity is subsequently performed, the rebound effect of the compression spring 6484 can be used to facilitate the movable plate 6485 to be pushed down and reset, so that the opening and closing blocks 6488 on both sides that are in the expanded state can be quickly recovered and reset along with the movable plate 6485 that automatically moves downward, so as to facilitate the contact of the locked state. In this way, a convenient recovery and unlocking activity can be achieved.

[0037] The utility model provides a wire-passing plug, which is provided with a connecting and fastening device 6, that is, under the threaded transmission of the screw 643 and the inner tube 644 arranged inside the locking component 64, the outer tube 645 can be conveniently moved downward, so that the outer tube 645 pushes the opening and closing structure 648 outward to the specified position for expansion and locking. At the same time, the limiting connection between the limiting grooves 646 and the limiting rings 647 opened on the left and right sides of the outer tube 645 can make the extension and contraction process of the outer tube 645 stable, thereby achieving the advantages of convenient transmission locking and improving the convenience of subsequent connection and locking. In addition, an opening and closing structure 648 is provided, that is, under the upward transmission of the moving plate 6485, the connecting arms 6487 arranged on both sides of the upper end can push out the opening and closing blocks 6488 for convenient expansion, thereby improving the sealing effect of the plug body 1 and the external wire-passing hole, reducing the occurrence of leakage and air leakage, thereby achieving the advantages of auxiliary connection and fastening of the wire-passing plug and improving the sealing performance.
