The beneficial effect who sets up like this is, adopt above-mentioned scheme, set up the constant head tank on the head, rubber packing ring terminal surface has the complex conflict flange with it, screw up the in-process at the bolt and rotate in step, the air in the bolt is screwed up in-process recess can be extruded and contact plane formation vacuum, rubber packing ring has certain thickness and elasticity simultaneously, can produce gyration around the certain limit when the connection environment receives vibrations influence, conflict flange is connected and vacuum fixation between rubber packing ring recess and the connector with the constant head tank cooperation, form the structure of similar sucking disc, make the whole gyration around the bolt in order to avoid the fastening inefficacy in controllable range, effectively improve overall structure's stability in use.
As a further arrangement of the present invention, the groove is set to be a plurality of and spaced from the end surface of the rubber gasket facing away from the head.
The beneficial effect who sets up like this is, adopts above-mentioned scheme for the area of contact of rubber packing ring and connecting piece is bigger, and the contact is more stable, and it is also better to adsorb the connection effect, and difficult emergence is not hard up, has good result of use.
As a further setting of the utility model, be connected through smooth curved surface between recess and the rubber packing ring.
The beneficial effect who sets up like this is, adopts above-mentioned scheme for when the rubber packing ring received the extrusion of head, subsides that can be better are established on the connecting piece is connected the face, and the air in the more effective discharge recess makes each groove position form the sucking disc, avoids not hard up of packing ring, has good result of use.
As a further setting of the utility model, the bolt head corresponds the positioning groove position and is provided with the strengthening rib.
The beneficial effect who sets up like this is, adopts above-mentioned scheme, effectively increases overall structure's joint strength, has good result of use.
As a further setting of the utility model, pole portion is including the screw thread section and the level and smooth section that are connected, the screw thread section is connected with the head through level and smooth section, the rubber packing ring cover is established on level and smooth section.
The beneficial effect who sets up like this adopts above-mentioned scheme for the combination of rubber packing ring and screw rod is more stable, and difficult drunkenness has good result of use.
