密封结构

Abstract

一种密封结构,包括:一弹出件,该弹出件一端开口设一输出管且于该弹出件中央径向表面设一环凸部,由该输出管套入一颈套,该颈套设轴向穿孔底端为一套合部套设于该输出管,且抵靠于该环凸部,该颈套底端与该弹出件之间设一个二次注塑的环状软胶;该弹出件相对应该输出管的另一端为一杆身,该杆身套设一弹性元件;一涂抹头,该涂抹头套设于该输出管;一盖体,该盖体设一轴向盲孔且开口处设一内螺纹,该内螺纹与内部该轴向盲孔交接处设一台阶;藉此,经由该台阶压紧或迫紧该环状软胶,达成该涂抹头密封的效果。
The utility model provides a sealing structure, includes: one pops out the piece, should pop out an one end opening and establish an output tube qieyu and should pop out the radial surface of central authorities and establish a ring convex part, embolias a neck cover by this output tube, and this neck cover is established axial perforation bottom and be the portion of registrating cover and locate this output tube, and supports to lean on and encircle the convex part in this, and this neck overlaps bottom and should pop out the cyclic annular flexible glue of establishing a secondary between the piece and moulding plastics, the other end that should pop out corresponding this output tube is a pole body, and an elastic element is established to this pole body cover, one scribbles and turns round, should scribble the headgear and locate this output tube, an axial blind hole is established to a lid, this lid and an internal thread is established to the opening part, and a step is established with inside this axial blind hole handing -over department to this internal thread, by this, compress tightly or compel tight this ring -type flexible glue via this step, reach this and scribble the sealed effect of turning round.
