Abstract
The utility model relates to a special threaded plug, which is characterized in that a pentagram notch is arranged at the end part of the plug; the plug is also provided with an internal cylindrical protrusion. The utility model is made from hot-melt rubber plastic material, and has the advantages of reasonable structure, smart design, easy injection molding, no cutting, mass production, special geometric structure, difficult opening without special tools, high reliability and high industry value.
Description
Technical field
The utility model relates to a kind of special screw thread pipe plug, the special screw thread pipe plug that uses on particularly a kind of water lines.
Background technique
The pipe plug that uses on water lines at present is hot melt rubber and plastic general part, adopts general utility tool to open arbitrarily.Also easily make on the pipeline of water filling thus, thereby caused line rupture protection valve to leak, cause damage by the irrational rough dismounting of people.
Summary of the invention
The purpose of this utility model is to provide a kind of can effectively overcome above-mentioned defective, and reliable and effective special screw thread connects sealing plug for pipe.The technical solution of the utility model is that a kind of special screw thread pipe plug is characterized in that: five jiaos of special-shapeds in the pipe plug end notch adopts, and be provided with interior cylindrical projections.
Owing to adopt such scheme, draw as drawing a conclusion, special-purpose pipe plug adopts the hot melt rubber-plastics material, is easy to adopt molding and forming not have cutting and produces in enormous quantities, and the morpheme structure is special, and non-special tool can't be opened easily, reliability height, tool industrial utilization.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a plan view of the present utility model.
Embodiment
Among the figure, sphere shape is adopted in the upper end portion 20 of special screw thread pipe plug body 10, five jiaos of special-shapeds in end notch 11 adopts, and cylindrical projections 12 in being provided with.During use, water pipe connects with the screwed pipe joint hot melt forms pipeline terminal, the stifled winding of special-purpose pipe plug thread joint face stuffing box packing, and inserting special-purpose pipe plug end notch with special spanner will seal in its screw-in pipeline terminal thread interface.What the special-purpose pipe plug end notch that is the utility model adopted is interior five jiaos of special-shapeds, does not contain general inner hexagon spanner; Cylindrical projections can be prevented the insertion of non-special tool in the notch; Sphere shape is adopted in the end of special-purpose pipe plug, can not be by big brank clamping dismounting.With the upper type characteristics, reached the technical purpose of this special-purpose pipe plug.At the material that does not change special-purpose pipe plug, moulding process, reliably inerrably reach sealing water lines port, prevent pipeline to be opened by people's mistake, cause the pressure release of leaking.
