The ring 6 is connected to the mounting plate 2 by adhesive fixation, and the inner walls on both sides of the upper and lower sides of the outer end of the connector 4 are provided with movable blocks 7, and the corresponding sides of the movable blocks 7 are provided with fastening wheels 8. The metering box body 1 of this structure can be abutted against the corresponding wall through the mounting plate 2 and fixed with bolts 3. After the bolts 3 are fixed, the connector 4 can be inserted into the plug-in interfaces at the four corners of the mounting plate 2. When the connector 4 is inserted, it can be fixed to each other by the first magnetic ring 5 and the second magnetic ring 6. The movable block 7 can be extended and retracted on the inner walls on both sides of the upper and lower sides of the outer end of the connector 4 to press the fastening wheel 8 against the corresponding position of the outer end of the bolt 3, so that the connector 4 can play a reinforcing role when the bolt 3 is fixed on the mounting plate 2, thereby enhancing the fastening effect of the bolt 3 and avoiding The bolts 3 are prone to a certain degree of loosening due to the gravity of the metering box body 1 for a long time, which reduces the problem of fastening effect, thereby ensuring the stability of the metering box body 1 when suspended and installed. The first magnetic ring 5 and the second magnetic ring 6 are both annular structures, and the corresponding side structures of the first magnetic ring 5 and the second magnetic ring 6 are consistent. The first magnetic ring 5 and the second magnetic ring 6 of this structure can be more closely adsorbed and fixed to each other to ensure the firmness of the connector 4 inserted at the four corners of the mounting plate 2.

A notch is provided on the outer side of the movable block 7, and both sides of the fastening wheel 8 are connected to the inner walls of the notch on the outer side of the movable block 7 through a rotating pin. The fastening wheel 8 of this structure can rotate in the notch on the outer side of the movable block 7 through the rotating pin to ensure that the plug-in component 4 is inserted and pushed forward more smoothly on the outside of the bolt 3.

[0019] Working principle: When using the plug-in structure for the metering box, first, place the metering box body 1 against the corresponding wall through the mounting plate 2 and fix the mounting bolts 3 at the four corners. When all four bolts 3 are fixed, the plug-in 4 is sleeved on the outside of the outer end of the bolt 3 and the inner end is pushed toward the plug-in interface of the mounting plate 2. During the insertion and pushing process of the plug-in 4, the fastening wheel 8 will rotate and contact with the outer end of the bolt 3. After the fastening wheel 8 is subjected to the pressure, it will drive the movable block 7 to move in the grooves of the upper and lower inner walls of the outer end of the plug-in 4. When the movable block 7 moves, it will press the pressure shaft 1. 0 is linked, and when the pressure shaft 10 is subjected to force, the spring 11 is stretched synchronously until the inner end of the connector 4 is inserted into the plug interface of the mounting plate 2 to a suitable depth, the first magnetic ring 5 and the second magnetic ring 6 are adsorbed and fixed to each other, and the fastening wheel 8 is also pressed against the corresponding position of the outer end of the bolt 3, and the holder 9 is also engaged with the outside of the outer end of the bolt 3.
