Abstract

The utility model relates to a locking ring for quickly assembling pipelines, which is composed of a taper sleeve with an opening, wherein annular ribs are arranged on the inner wall of the taper sleeve. When pipelines are connected, the annular ribs on the inner wall of the locking ring are pressed by an inner cone of a compression nut and an inner cone of a pipeline connector into the outer wall of a pipeline to be connected. The friction force between the locking ring and the pipeline to be connected is increased, so the connection strength between the pipeline and a pipe connector is enhanced.

Description

The fast-assembling Pipeline lock presses ring

The utility model relates to a kind of locking pressure ring, in particular for the locking pressure 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 lock of a kind of join strength and presses ring.

For achieving the above object, the utility model is by the following technical solutions:

A kind of fast-assembling Pipeline lock presses ring, is made of the opening tapered sleeve, it is characterized in that: be shaped on the ring muscle on the inwall of described tapered sleeve.

During connecting tube, fastening with gland nut, the locking pressure ring is by the compressing of the inner cone of the inner cone of pipe connector and gland nut, is subjected to its compressing and produces bigger radial component, and the ring muscle on the locking pressure ring inwall is pressed into the outer wall of being joined two pipes together.Because the ring muscle of this locking pressure ring has increased locking pressure ring and the quilt frictional force between joining two pipes together, 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 sectional view figure 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 pressure ring 1 is made of opening tapered sleeve 3, is shaped on ring muscle 2 on the inwall of tapered sleeve 3.

In Application Example shown in Figure 3: the termination portion cover seal ring 4 of connected lining plastic aluminium alloy pipe 6, there is outside thread the termination of pipe connector 5, and a frustum is arranged in the termination, and gland nut 7 has frustum in.To lock pressure ring 1 and be enclosed within on the pipe 6, screw gland nut 7.Along with screwing of gland nut 7, the big end of locking pressure ring 1 is earlier with seal ring 4 ascending pipe fittings 5, big end until locking pressure ring 1 contacts with the end face of pipe connector 5, the male cone (strobilus masculinus) of locking pressure ring 1 contacts with the inner conical surface of gland nut 7, be subjected to its compressing to produce bigger radial component, ring muscle on locking pressure ring 1 inwall is pressed into 6 the outer wall of being joined two pipes together, realizes the locking of pipe 6 and pipe connector 5.Because the ring muscle of locking pressure ring 1 inwall has increased locking pressure ring 1 and the frictional force of being joined two pipes together between 6, so the join strength of pipe 6 and pipe connector 5 is improved.

In order to strengthen frictional force with further raising join strength, can end, small end, center be all made ring muscle 2 greatly on the inwall of tapered sleeve 3.

Claims

1. a fast-assembling Pipeline lock presses ring, is made of the opening tapered sleeve, it is characterized in that: be shaped on the ring muscle on the inwall of described tapered sleeve.

2. fast-assembling Pipeline lock as claimed in claim 1 presses ring, it is characterized in that: be positioned at that end, small end, center all are shaped on the ring muscle greatly on the inwall of described tapered sleeve.
