[0027] The connecting assembly includes: a connecting sleeve 2 arranged at the top of the filling connector 11, docking grooves 21 provided at the top and bottom of the connecting sleeve 2, and an external charging head 22 threadedly connected to the inner side of the docking groove 21 at the top of the connecting sleeve 2; the inner side of the docking groove 21 at the bottom of the connecting sleeve 2 is threadedly connected to the side of the filling connector 11, and a one-way valve 23 is fixed to the inner side of the connecting sleeve 2; a rotation-stop assembly for improving the tightness of the connecting sleeve 2 after connection, and a sensor assembly for monitoring data during industrial gas filling are provided on the side of the connecting sleeve 2.

[0028] It should be noted that the docking grooves 21 located at the top and bottom of the connecting sleeve 2 are both connected to the inner side of the connecting sleeve 2; the gas flow direction of the one-way valve 23 is from the external charging head 22 to the filling connector 11; when the external charging head 22 needs to be docked with the filling connector 11 for industrial gas filling, the docking grooves 21 located at the top and bottom of the connecting sleeve 2 are threadedly connected to the external charging head 22 and the filling connector 11 respectively. When the industrial gas filling equipment uses the external charging head 22 to inflate the filling tank body 1 through the connecting sleeve 2, the one-way valve 23 on the inside of the connecting sleeve 2 can prevent gas backflow. At the same time, the cooperation between the sensor component and the data receiving unit can monitor the gas filling process, thereby improving the visibility and safety of the industrial gas filling process.

[0029] The inner diameter of the docking groove 21 at the bottom of the connecting sleeve 2 is the same as the outer diameter of the filling joint 11 , and the inner diameter of the docking groove 21 at the top of the connecting sleeve 2 is the same as the outer diameter of the external filling head 22 .

[0030] It should be noted that, by setting the outer diameters to be the same, the docking groove 21, the filling connector 11 and the external inflation head 22 can be tightly screwed together after being threadedly connected.

[0031] like Figure 3 As shown, the anti-rotation assembly includes: a plurality of hinge blocks 3 respectively fixed on both sides of the connecting sleeve 2 near the bottom and the top, a plurality of connecting rods 31 hinged on the inner sides of the hinge blocks 3, and a plurality of anti-rotation docking rings 32 fixed on the side of the connecting rods 31 facing the connecting sleeve 2; a connecting plate 33 is fixed on one side of the anti-rotation docking ring 32.

[0032] It should be noted that the number and distribution position of the connecting rods 31, the anti-rotation docking rings 32 and the connecting plates 33 are the same as those of the hinge block 3. The inner sides of the adjacent anti-rotation docking rings 32 located at the bottom of the connecting sleeve 2 are in contact with the side of the filling connector 11, and the inner sides of the adjacent anti-rotation docking rings 32 located at the top of the connecting sleeve 2 are in contact with the side of the external inflator head 22; the adjacent connecting plates 33 are connected by bolts and nuts, pins or one of the methods of clamping; when the filling connector 11 and the external inflator head 22 are connected to the two ends of the connecting sleeve 2, the several connecting rods 31 on both sides of the connecting sleeve 2 are manually tightened. The cooperation of the dry hinge block 3 drives the several anti-rotation docking rings 32 on one side of the several connecting rods 31 to flip, so that the adjacent anti-rotation docking rings 32 located at the bottom of the connecting sleeve 2 are tightly against the side of the filling connector 11, and the adjacent anti-rotation docking rings 32 located at the top of the connecting sleeve 2 are tightly against the side of the external charging head 22.

[0033] The inner side of the anti-rotation docking ring 32 is provided with anti-skid grooves, and the anti-skid grooves can play an anti-skid and stable role when the filling connector 11 and the external inflation head 22 are connected to the connecting sleeve 2.

[0034] A plurality of sealing rings 4 are arranged on the inner side of the docking groove 21 . The arrangement of the plurality of sealing rings 4 can ensure the sealing performance of the connection between the filling connector 11 and the external inflation head 22 and the docking groove 21 .

[0035] The sensing assembly includes: a pressure sensor 5 and a flow sensor 51 fixed to the connecting sleeve 2 at the bottom side of the one-way valve 23; the pressure sensor 5 and the flow sensor 51 are both electrically connected to the data receiving unit.

[0036] It should be noted that, through the arrangement of the pressure sensor 5 and the flow sensor 51, during the process of filling gas into the filling tank body 1, the pressure sensor 5 can monitor the gas pressure of the filling process, and the flow sensor 51 can monitor the gas flow of the filling process, and transmit the gas pressure and flow data to the data receiving unit, so as to provide the user with data during industrial gas filling monitoring.

By setting the outer diameters to be the same, the docking grooves 21, the filling joint 11 and the external inflating head 22 can be tightly screwed together after being threadedly connected. A plurality of sealing rings 4 are used to ensure the sealing of the connection between the filling joint 11 and the external inflating head 22 and the docking grooves 21. When the filling joint 11 and the external inflating head 22 are connected to the two ends of the connecting sleeve 2, the plurality of connecting rods 31 on both sides of the connecting sleeve 2 are manually turned over through the cooperation of the plurality of hinge blocks 3, so that the adjacent non-rotating docking rings 32 located at the bottom of the connecting sleeve 2 are tightly attached to the side of the filling joint 11, and the adjacent non-rotating docking rings 32 located at the top of the connecting sleeve 2 are tightly attached to the side of the filling joint 11. The anti-rotation docking ring 32 is tightly attached to the side of the external charging head 22, and the adjacent connecting plates 33 are connected and fixed by bolts and nuts, pins or clamping, and the anti-slip grooves play a role of anti-slip and stability, so that the connection position of the connecting sleeve 2 and the filling connector 11 and the external charging head 22 can be further limited to prevent loosening. When the industrial gas filling equipment uses the external charging head 22 to inflate the filling tank body 1 through the connecting sleeve 2, the one-way valve 23 on the inside of the connecting sleeve 2 can prevent gas backflow. At the same time, the pressure sensor 5 can monitor the gas pressure of the filling process, and the flow sensor 51 can monitor the gas flow of the filling process, and transmit the gas pressure and flow data to the data receiving unit, which is used to provide the user with data during industrial gas filling monitoring.
