Abstract
An intramural snap ring outside thread shield is for the worm protection of polyethylene and other tubular product's inner connection. On the upside of the cap is an eave. The downside of the eave's surrounding curves inward. A twist grip is mounted on the cross connection on the central section of the eave. The downside of the inner wall of the cap tightens outward and forms a platform. But still the cap body is integrity. On the inner wall of the cap installed some circular snap rings. The snap rings bulge out of the cap inward. The upside of snap rings tighten from up to down, and form 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 outside thread protection at present is jacket-type, generally is to be provided with protruded object at the tin hat inwall, is used for increasing the friction force of tin hat and protective tube, comes off to prevent tin hat.But in practice,, often be difficult to the protection effect that reaches desirable, have the vibrations tin hat just to be easy to come off slightly because tin hat inwall protruded object design is unreasonable.
Summary of the invention
The purpose of the present utility model provide a kind of can with tube wall closed contact, not caducous external-thread protector.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 inwall bottom is outwards 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 cap body inwall, described snap ring inwardly protrudes from the cap body, inwardly takes in from top to bottom at the position, top of each snap ring and forms lower inclined plane.Like this, when the cap body being enclosed within the pipe outer 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, itself and the inside recessed formation groove 6 of cap body 1 connecting portion.2 middle parts laterally are connected with and revolve 5 in the upper edge, and cap body 1 inwall bottom is outwards tightened formation and moved back platform 4.Be provided with some ring-like snap rings 3 at cap body 1 inwall, described snap ring 3 inwardly 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 being enclosed within the pipe outer 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.
