Abstract
A detachable ring has a safety collar having an inner thread, an annular lower end and a taper upper end, and a main body having a first end having an end flange and a second end having an annular block and an outer thread. The inner thread of the safety collar engages with the outer thread of the second end of the main body. The annular block blocks the annular lower end of the safety collar. The taper upper end of the safety collar encloses the end flange of the first end of the main body.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a detachable ring. More particularly, the present invention relates to a detachable ring which can be detached easily and quickly.
Referring to
FIGS. 1 and 2
, a conventional detachable ring has a main body
10
′, a safety collar
20
′ having an inner thread
21
′, and the main body
10
′ having a first end
101
′ having an outer thread
11
′ and a second end
102
′ having an outer thread
12
′. When the safety collar
20
′ engages with the first end
101
′ of the main body
10
′ and the second end
102
′ of the main body
10
′, the conventional detachable ring is closed. When the safety collar
20
′ disengages from the second end
102
′ of the main body
10
′, the conventional detachable ring is opened. If the first end
101
′ of the main body
10
′ does not match the second end
102
′ of the main body
10
′ precisely, the safety collar
20
′ cannot engage with both the first end
101
′ of the main body
10
′ and the second end
102
′ of the main body
10
′ at the same time. When the conventional detachable ring is opened, the safety collar
20
′ should disengages from both the second end
102
′ of the main body
10
′ and the first end
101
′ of the main body
10
′ slowly.
SUMMARY OF THE INVENTION

.
The annular block
13
blocks the annular lower end
23
of the safety collar
20
.
The taper upper end
22
of the safety collar
20
encloses the end flange
14
of the first end
101
of the main body
10
.
The detachable ring is made of a metal.
Referring to
FIGS. 5
to
7
again, the safety collar
20
disengages from the second end
12
of the main body
10
. A rope
