A combined cover based on a riveted structure, as shown in fig. 1-12, comprises an outer cover 1, a rubber plug 2 and a pressure pad 3; the outer cover 1 comprises an outer cover body 11 and a rubber plug chamber 12 arranged above the outer cover body 11, a mounting area 13 for mounting the pressure pad 3 is arranged at the joint of the outer cover body 11 and the rubber plug chamber 12, the mounting area 13 extends downwards to form a connecting part 14, and the top surface of the rubber plug chamber 12 is provided with a dosing hole 15 and a transfusion hole 16; the rubber plug 2 is arranged in the rubber plug chamber 12 and is tightly attached to the inner wall of the rubber plug chamber 12; the pressure pad 3 is provided with a connecting hole 31 matched with the connecting part 14; during the equipment, in plug room 12 was filled in to plug 2, the pressure pad 3 was installed in installing zone 13, and the upper surface top of plug 2 is tight in the interior top surface of plug room 12, and its lower surface top is tight in the upper surface of pressure pad 3, and then realizes enclosing cover 1 inside and outside sealed. When the pressure pad 3 is connected with the outer cover 1, the connecting part 14 on the outer cover 1 passes through the connecting hole 31, the end part of the connecting part 14 protrudes out of the connecting hole 31, and then the protruding part of the connecting part 14 is bent by 90 degrees through a hot bending machine; of course, the protruding portion of the connecting portion 14 may be riveted by a hot riveting machine, so that the protruding portion is melted and solidified into a rivet head.

In one embodiment, as shown in FIGS. 1-12, a first through hole 32 and a second through hole 33 are provided on the pressure pad 3, and the first through hole 32 and the second through hole 33 are aligned with the drug adding hole 15 and the infusion hole 16, respectively. Namely, the medicine adding hole 15 is aligned with the first through hole 32 up and down, the transfusion hole 16 is aligned with the second through hole 33 up and down, when medicine liquid needs to be injected into the transfusion bag, the needle is punctured into the medicine adding hole 15, the medicine liquid is punctured into the transfusion bag from the first through hole 32 after the rubber plug 2 is punctured, and then the medicine liquid can be added into the transfusion bag. When infusion is performed, only the infusion needle needs to be inserted into the infusion hole 16. The outer cover 1 and the pressure pad 3 are provided with holes in advance, so that the use is more convenient, and the needle head is easier to pierce.

In an embodiment, as shown in fig. 1 to 12, the upper surface of the pressure pad 3 is convexly provided with a first sealing rib 34 around the first through hole 32 and the second through hole 33, and the lower surface of the rubber plug 2 is concavely provided with a first sealing groove 21 corresponding to the first sealing rib 34.

In one embodiment, as shown in fig. 1 to 12, the inner top surface of the plug chamber 12 is provided with a second sealing rib 17 protruding around the dosing hole 15 and the infusion hole 16, and the upper surface of the plug 2 is provided with a second sealing groove 22 recessed to match with the second sealing rib 17.
