Abstract
A screw head relates to a seal piece of a tube head, comprising a screw head (1). A screw thread (1-1) is arranged on the lower end of the screw head (1); a sealed circular slot (1-2) is arranged on the middle of the screw head (1); a clamping surface (1-3) of multilateral structure is arranged on the upper end of the screw head (1). The utility model is of simple structure and easy processing, which increases the cross sectional area of the fastening end and can form the clamping surface of multilateral structure on the clamping end so that the screw thread on the connecting position can basically keep consistent with the service life of the clamping surface of the fastening end to reduce waste caused by inadequate structural design.
Description
Technical field: the utility model relates to the sealing member of tube head.
Background technology: the seal structural part of tube head has varied at present, prevailing is that an end is and the screw thread of wanting leak free spare to match, the other end is the fastening end, the centre is a seal stopper ring, because the fastening end cross-sectional area is little, easily the place of being installed is damaged during loading and unloading, cause end socket to damage and scrap, and cause unnecessary waste.
Summary of the invention: the utility model is a kind of Screw-thread sealing plug of development, and this Screw-thread sealing plug should have the characteristics that fastening end and threaded ends conform to service life.The utility model comprises Screw-thread sealing plug 1, is provided with screw thread 1-1 in the lower end of Screw-thread sealing plug 1, is provided with seal groove 1-2 in the centre of Screw-thread sealing plug 1, is provided with the face that the is installed 1-3 of polygon structure in the upper end of Screw-thread sealing plug 1.The utility model is simple in structure, be easy to processing, owing to increased the cross-sectional area of fastening end, can make the face that is installed of polygon structure in the fastening end, make the screw thread of junction and the face that is installed of fastening end reach basically identical service life, reduce because of the not enough waste that causes of structure design.
Description of drawings: Fig. 1 is a front view of the present utility model, and Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment: present embodiment comprises Screw-thread sealing plug 1, is provided with screw thread 1-1 in the lower end of Screw-thread sealing plug 1, is provided with seal groove 1-2 in the centre of Screw-thread sealing plug 1, is provided with the face that the is installed 1-3 of six-sided structure in the upper end of Screw-thread sealing plug 1.Because the face that is installed is many, can increase the service life of fastening end.
