Abstract
A declivity snap ring plugged protective cap is for the worm protection of polyethylene and other tubular product's inner connection. On the upside of the cap is an eave, and a twist grip is installed on the cross connection on the central section of the eave. The underneath of the cap tightens inward and forms a platform. But still the cap body is an entirety. On the ektexine of the cap are some circular snap rings. The snap rings bulge out of the cap. The upside of the snap rings contract inward and forms a declivity slant. Since the snap ring forms a declivity slant, the cap inserting of the external wall of duct is easy, and the protection cap is not easy to drop off.
Description
Affiliated technical field
The utility model 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 the present utility model provide a kind of can with tube wall closed contact, not caducous negative thread tin hat.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.
Figure of description
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the utility model semi-section structural representation.
Fig. 2 is the utility model birds-eye view.
The specific embodiment
The utility model is to be 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.
