Furthermore, the outer walls of the opposite sides of the pair of rubber strip bodies are respectively provided with a middle seam outer sealing edge. The outer sealing edge of the middle seam is used for sealing a gap between the rubber strip body and the plane of the outer wall of the door panel.

Furthermore, the inner walls of the opposite sides of the rubber strip bodies are respectively provided with a middle seam inner sealing edge. The inner sealing edge of the middle seam is used for sealing a gap between the rubber strip body and the plane of the inner wall of the door panel.

Furthermore, a hollow cavity is arranged in the tenon-and-mortise bulge. The setting up of cavity on the one hand can play certain cushioning effect to the centre joint strip when closing the door, makes the adhesive tape body of both sides have bigger deformation effect after extrudeing each other simultaneously, improves centre joint strip's sealed effect, and on the other hand can alleviate centre joint strip's weight, material cost is saved.

The utility model also provides a door plant, including foretell middle joint strip of fluid sealant subassembly.

The utility model also provides a sliding plug door, including foretell middle joint strip of sealant subassembly.

Has the advantages that: when installing the sealed rubber strip subassembly of centre joint on the both sides door plant of stopper sliding door, with the centre joint door plant jack catch card of both sides adhesive tape body one side in the section bar of both sides door plant opposite side can, need notice simultaneously and need the cooperation of tenon fourth of twelve earthly branches between tenon fourth of twelve earthly branches recess and the tenon fourth of twelve earthly branches arch just can reach effectual sealed effect. The setting of the middle joint sealing rubber strip component enables the sliding plug door to achieve the purpose of effectively sealing the door panel after the door panel is closed, and the door panel is prevented from shaking, air inlet, rainwater inlet and the like in the running process of a vehicle.
