The utility model has the advantages that:
(1) the utility model discloses inside the body of cock was filled in tubular product during the use, the gag can wrap up mouth of pipe department copper pipe completely including with outer cladding layer, and the gag front end also wraps up in the copper outside of pipe, and wraps up in the copper pipe entrance, strengthens the protection around the copper pipe entry, prevents that the copper pipe at transportation here from being bumped flat or gouged.
(2) The invention has the advantages of easy integral plugging and unplugging, large friction force and good sealing and air-sealing performance, when in use, the plug cover and the inner plug body can be pressed by force to deform the inner plug body and the buffer holes in the plug cover, so that the rubber plug is easy to plug into the tube, the rubber plug is restored to be filled in the tube after entering the tube and is completely attached to the tube to realize sealing, and when the rubber plug needs to be unplugged, the plug cover is pressed by force to deform the inner plug body and the buffer holes in the plug cover, so that the inner plug body and the buffer holes in the plug cover are easy to be unplugged.
(3) Be equipped with the buffer hole and can then improve the anti-seismic force of rubber buffer and make tubular product receive and come from external extrusion collision time buffer hole can unload too much impact force through the buffering, and the buffer hole anterior segment is established to arc and has avoided because the extrusion leads to the buffer hole junction fracture.
(4) And the appearance of a part of products using the rubber plugs needs to be subjected to paint spraying and rust preventing treatment on a production line. Because metal pipes (aluminum pipes, copper pipes and steel pipes) need to be welded with a terminal freezer, the cleanness of the joints of the metal pipes needs to be ensured, and then a single procedure is needed for performing joint paint prevention protection on the metal pipes in a product production line. The invention can play a role of paint prevention of the metal pipe connector, can reduce one added protection process of a production line, and provides great help for optimizing the production process of products and saving the cost.
