Abstract

The utility model relates to a fast assembled pipeline locking ring which is composed of a taper sleeve with an opening, wherein both end surfaces of the taper sleeve is provided with introversive cutting edges. When pipelines are connected, the introversive cutting edges on both ends of the locking ring are respectively pressed into the outer walls of connected pipelines by an inner cone of a pressing but and an inner cone of a pipeline connector, and the friction force between the locking ring and the connected pipelines is increased. Therefore, the connection strength of the pipelines and the pipeline connector is enhanced.

Description

Fast-assembling pipeline locking ring
The utility model relates to a kind of locking ring, in particular for the locking ring of fast-assembling pipeline.
The pipe that exists in connecting at pipeline needs prior tapping, complicated operation, problem that installation strength is big, multiple fast-assembling pipe coupling occurred.The CN2178825 patented invention a kind of " fast-assembling pipe coupling ", it is made up of pipe connector, gland nut, seal ring, locking ring, seal ring, locking ring are taper type, in the termination of pipe connector frustum is arranged, gland nut has a frustum, and the frustum of seal ring and the frustum of locking ring place respectively in the frustum of the frustum of pipe connector and gland nut.Its advantage is that connected pipe does not need tapping just can be connected with this pipe coupling, and simple to operate, installation rate is fast.But find that in practice its locking ring structure can also improve.
In view of above-mentioned, the purpose of this utility model just provides the high fast-assembling pipeline locking ring of a kind of join strength.
For achieving the above object, the utility model is by the following technical solutions:
A kind of fast-assembling pipeline locking ring is made of the opening tapered sleeve, it is characterized in that: the cutting edge that turns in two end faces of described tapered sleeve all are shaped on.
During connecting tube, fastening with gland nut, the small end of locking ring is turned over cutting edge and is pressed into the outer wall of being joined two pipes together by the compressing of the inner cone of pipe connector in its small end, the big end of the inner cone compressing locking ring of gland nut is pressed into the outer wall of being joined two pipes together with turning over cutting edge in holding greatly.Increased the frictional force of locking ring between joining two pipes together with quilt owing to turn over cutting edge in two of this locking ring, so improved the join strength of pipe and pipe connector greatly.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is a structural drawing of the present utility model; Fig. 2 is the side view of Fig. 1;
Fig. 3 is an enforcement illustration of the present utility model.
See also Fig. 1,2.The utility model locking ring 1 is made of opening tapered sleeve 4, the cutting edge 2 that turns in the small end end face of tapered sleeve 4 is shaped on, the cutting edge 3 that turns in its big end end face is shaped on.
In the utility model Application Example shown in Figure 3: the termination point casing seal ring 6 of connected lining plastic aluminium alloy pipe 8, there is outside thread the termination of pipe connector 5, has a frustum, gland nut 7 that frustum in is arranged in its termination.Locking ring 1 is enclosed within on the pipe 8, screws gland nut 7.Screw in the process at gland nut 7, the small end of locking ring 1 contacts with the inner conical surface of pipe connector 5, be subjected to its compressing and produce radial component, turn over cutting edge 2 in its small end and be pressed into 8 the outer wall of being joined two pipes together, the big end of locking ring 1 then is subjected to the inner cone compressing of gland nut 7 and produces radial component, is pressed into 8 the outer wall of being joined two pipes together with turning over cutting edge 3 in the end greatly.Increased locking ring 1 and the frictional force of being joined two pipes together between 8 owing to turn over cutting edge in two of locking ring 1, so the join strength of pipe 8 and pipe connector 5 is improved.
