Abstract
This invention relates to an internal thread jacket of a tip, in which, a top edge is set at the upper part of a cap, a horizontally connected spin handle is set at the middle of the upper edge, the lower part of the cap contracted inward to form a back stand, several binding rings are set on the outside wall of the cap projecting over the cap to shrink inward from the top to form a down slant, thus it is easy to insert the cap into the inside wall of a tube since the rings are down slant.
Description
Affiliated technical field
The present invention is used for polyethylene and the interior connecting thread protection of other tubing is used.
Background technology
The pipe cap of negative thread protection at present has bottle stopper formula and jacket-type, adds draw-in groove and snap ring is in the majority so that cap is external in bottle stopper formula class tin hat.But the snap ring class just simply adds common ring-like projection in that cap is external, and shaking tin hat slightly will come off.
Summary of the invention
The purpose of this invention is to provide a kind of can with tube wall closed contact, not caducous Pipehead internal-thread sleeve.For achieving the above object, the present invention is achieved in that on the top of cap body and is provided with the upper edge that peripheral bottom, upper edge is inwardly recessed.Laterally be connected with at upper edge middle part and revolve handle, cap body bottom is inwardly tightened to form and is moved back platform, but with the cap body still be an integral body.Be provided with some ring-like snap rings at the external wall of cap, described snap ring protrudes from the cap body, inwardly takes in from top to bottom at position, snap ring top and forms lower inclined plane.Like this, when the cap body is filled in inside pipe wall, because snap ring is a lower inclined plane, so fill in easily.It is same because the effect of snap ring lower inclined plane makes tin hat be not easy to come off.
The present invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a Pipehead internal-thread sleeve semi-section structural representation of the present invention.
Fig. 2 is a Pipehead internal-thread sleeve birds-eye view of the present invention.
The specific embodiment
The present invention is provided with upper edge 2 on the top of cap body 1, and 2 middle parts laterally are connected with and revolve 5 in the upper edge, and cap body 1 bottom is inwardly tightened formation and moved back platform 4.Be provided with some ring-like snap rings 3 at cap body 1 outer wall, described snap ring 3 protrudes from cap body 1, inwardly takes in from top to bottom at position, snap ring 3 top and forms lower inclined plane.Like this, when cap body 1 is filled in inside pipe wall, because snap ring 3 is a lower inclined plane, so fill in easily.It is same because the effect of snap ring 3 lower inclined planes makes tin hat be not easy to come off.
