Abstract
The invention discloses a nose end invisible sealing end cover. The nose end invisible sealing end cover comprises an end cover, a steel ball, a sealing ring, a fastening screw and a sleeve. The end cover of the nose end invisible sealing cover structure is matched in a sleeve hole through a hole shaft; a semi-circular ring groove is formed in the outer circle of the end cover; a semi-circular ring groove of the same size is formed in the inner hole of the sleeve at a corresponding position; a complete circular ring is formed by the semi-circular ring grooves of the end cover and the sleeve; a threaded inner hole for fastening screw is formed in ring groove in the sleeve and is communicated with the ring groove; the steel ball enters the complete circular ring formed by the end cover and the sleeve from the threaded inner hole; the end cover and the sleeve are limited along the axial direction; the end of the end cover is flush with the end face of the sleeve without any mark; the sealing ring is assembled on the outer circle of the inner side of the end cover to play a role in sealing; the fastening screw is locked after the steel ball is assembled.
Description
Technical field
The invention relates to a kind of end cover sealing structure, belongs to mechanical device, is mainly used in the sealing of sleeve or casing nose end.
Background technique
In the end part seal application of sleeve or box body hole, most of employing exposed step end bracket enclosed, screw-thread fit seal arrangement, and smooth during without exposed parts when needs nose end, step end cap just cannot be realized.
Summary of the invention
For realizing aperture without the smooth sealing exposing, the invention provides a kind of nose end simple in structure, that mounting or dismounting are convenient, with low cost stealthy sealing cover structure, by have semicircle annular groove on endoporus and end cap simultaneously, put into steel-ball limiting, reach location sealing effect.
The technological scheme of the invention is: without the stealthy sealing cover structure of the nose end exposing, comprise end cap, steel ball, seal ring, Cock screw, sleeve for aperture.The end cap of the stealthy sealing cover structure of described nose end is engaged in sleeve hole by hole axle, is provided with semicircle annular groove on the cylindrical of end cap, is provided with onesize semicircle annular groove on the endoporus of the sleeve of corresponding position, and the semicircular ring groove of end cap and sleeve forms complete circle; The threaded interior hole that has Cock screw on described sleeve in annular groove position communicates with annular groove, and steel ball enters the complete circle of end cap and sleeve formation from threaded interior hole, end cap and sleeve axial limiting, and end cap end is concordant with sleeve end face without vestige; Described seal ring is assemblied on the inner side cylindrical of end cap and bears seal action, Cock screw locking after steel ball assembling.
Brief description of the drawings
Accompanying drawing 1 is the stealthy sealing cover structure schematic diagram of the invention nose end.
Embodiment
Referring to accompanying drawing, the invention provides a kind of nose end stealthy sealing cover structure, comprises end cap 1, steel ball 2, seal ring 3, Cock screw 4, sleeve 5.
The end cap 1 of the stealthy sealing cover structure of described nose end is engaged in sleeve 5 holes by hole axle, on the cylindrical of end cap 1, be provided with semicircle annular groove, on the endoporus of the sleeve 5 of corresponding position, be provided with onesize semicircle annular groove, the semicircular ring groove of end cap 1 and sleeve 5 forms complete circle.
The threaded interior hole that has Cock screw 4 on described sleeve 5 in annular groove position communicates with annular groove, and steel ball 2 enters from threaded interior hole the complete circle that end cap 1 and sleeve 5 form, end cap 1 and sleeve 5 axial limitings, and end cap 1 end is concordant without vestige with sleeve 5 end faces.
Described seal ring 3 is assemblied on the inner side cylindrical of end cap 1 and bears seal action, the locking after steel ball assembling of described Cock screw 4.
