Disclosure of Invention
The utility model aims at solving the problems in the prior art, and provides a plastic screw plug, which aims at solving the technical problems that: how to solve the problem that the sealing gasket is easy to be corroded by oxidation.
The aim of the utility model can be achieved by the following technical scheme:
the utility model provides a plastics plug screw, includes sealed pad and the plug screw main part of being made by plastics material, the outer peripheral face of the lower part of plug screw main part has the external screw thread, its characterized in that, the lower terminal surface of plug screw main part has the bellied erection column downwards, the lower extreme of erection column has and is annular spacing flange, be formed with the mounting groove between the upper surface of spacing flange and the lower terminal surface of plug screw main part, sealed pad is located the mounting groove and overlaps to establish on the erection column.
The screw plug main body is suitable for a channel with a step surface inside, the screw plug main body is connected in a port of the channel through external threads, the sealing gasket is abutted against the step surface, the sealing gasket is extruded along with the further screwing of the screw plug main body, the sealing gasket is deformed after being extruded, namely, the sealing gasket is slightly flattened, the sealing gasket is outwards expanded, the outer peripheral surface of the sealing gasket is tightly attached to the inner wall of the channel, sealing is realized, and the sealing gasket is positioned in the channel, and the screw plug main body and the channel are in threaded connection to form certain sealing, so that the sealing gasket is basically isolated from the outside, is not easy to oxidize and corrode, and the service life of the sealing gasket is obviously prolonged.
In the plastic screw plug, the outer diameter of the sealing gasket is larger than the outer diameter of the limit flange.
Through the setting of this structure, limit flange can play the effect of stepping down when carrying out spacingly to sealed pad again, guarantees that sealed pad can be with step face contact for sealed pad can atress deformation.
In one of the plastic screw plugs described above, the upper portion of the plug body has an outer hexagonal head.
Through the setting of this structure, make things convenient for the hexagonal socket to rotate the plug main part, promoted the convenience of plastics plug screw installation.
In the plastic screw plug, the upper end surface of the screw plug main body is provided with the inner hexagonal counter bore along the axial direction of the screw plug main body.
Through the setting of this structure, make things convenient for the hexagonal spanner to rotate the plug main part for the installation of plastics plug screw is more convenient.
In the plastic screw plug, the bottom surface of the inner hexagonal counter bore is provided with a cross groove.
Through the setting of this structure, make things convenient for the cross screwdriver to rotate the plug main part, conveniently adopt current common instrument to install.
Compared with the prior art, the plastic screw plug has the following advantages: the sealing gasket of this structure takes place deformation after receiving the extrusion, and the sealing gasket takes place slight flattening for sealing gasket outwards expands, and the outer peripheral face of sealing gasket takes place closely laminating with the inner wall of passageway, realizes sealing, because sealing gasket is located the passageway to screw plug main part and passageway threaded connection have also formed certain seal, make sealing gasket keep apart basically with external world, and sealing gasket is difficult for being by oxidation and corruption, the life of the sealing gasket of showing the extension.
