Description

eleven

This invention relates to threaded safety devices for protecting threaded ends of pipes or couplings for them,

The purpose of the invention is to simplify the design and improve the manufacturability by making a collar from individual petals bent in staggered order, formed by slots at one of the ends of the threaded cone.

FIG. 1 shows safety devices screwed with a pipe and coupling; in fig. 2 - safety device with internal thread, general view; in fig. 3 is a view A of FIG. 2; in fig. 4 - device with external thread, general view; FIG. 5 is a view B of FIG. four,

The safety device for threaded pipe ends consists of a threaded cone 1, on one of the ends of which there are slots 2,

forming petals 3, some of which are bent and form a collar q, and the remaining non-bent petals form elements for tightening 5 f.

Depending on the type of thread on the cone (inner or outer), the slits 2 are made at the end of a smaller or larger diameter, respectively.

A device with an internal thread on the housing 1 is screwed onto the ends of the pipes 4 (Fig. 1 and 5);

15 (THEM from the impact of the end face and damage to the thread. The tightening elements S allow fast insertion of the safety device without resorting to an additional tool.

20 When to protect

The thread and the end of the coupling use a safety device with an external thread on the cone 1 (FIGS. 1 and 4).
