Description

Detachable joint for plastic tube

Technical field

The utility model relates to plastic article manufacturing technology field, especially a kind of joint that has between pipe.

Background technique

The igelite waste pipe is own through being widely used in the national economy every field at present, and the joint for plastic tube that connects the igelite waste pipe is one of them pith; In prior art, a kind of pvc tube joint is arranged, comprise inner sleeve, positioning ring, cutting ferrule, seal ring and outer sleeve, wherein seal ring is placed in the groove of outer sleeve, the cutting ferrule subcard advances the groove outer wall of outer sleeve, inner sleeve inserts the inner chamber of outer sleeve, directly polychloroethylene pipes is inserted the inner chamber of inner sleeve during use, positioning ring is sticked into the outer wall of inner sleeve.

There is following deficiency in this joint for plastic tube:

1, pipe joint structure is complicated, and part is more, and manufacture cost is high.

2, this joint dismounting inconvenience, in the time of need to changing seal ring when joint leaks, seal ring is difficult to take out, and is therefore difficult in maintenance, often needs whole pipe joint is destroyed, and causes unnecessary waste.

The model utility content

The purpose of this utility model is to provide a kind of detachable joint for plastic tube, and this pipe joint can solve the problem of joint for plastic tube complex structure of the prior art, dismounting inconvenience, maintenance difficult.

In order to address the above problem, the technical solution adopted in the utility model is:

This detachable joint for plastic tube comprises that opening end is provided with diameter greater than the outer sleeve and the seal ring that is contained in described expanded bore of the expanded bore in inner aperture, has been threaded connection a pressure ring on the port of the expanded bore of described outer sleeve; Described seal ring is that head end is provided with socket, and end is provided with the bar of plug.

In above technological scheme, further scheme can be: have a body to be inserted in described outer sleeve, described seal ring is crimped between described outer sleeve, body and pressure ring.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, the detachable joint for plastic tube is simple in structure, part is few, low cost of manufacture.

2, the installation, maintenance of detachable joint for plastic tube is convenient.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawing example:

In prior art shown in Figure 1, a kind of pvc tube joint is arranged, comprise inner sleeve 11, positioning ring 12, cutting ferrule 14, seal ring 13 and outer sleeve 15, wherein seal ring 13 is placed in the groove of outer sleeve 15, cutting ferrule 4 sticks into the groove outer wall of outer sleeve 15, inner sleeve 11 inserts the inner chamber of outer sleeve 15, directly polychloroethylene pipes is inserted the inner chamber of inner sleeve 11 during use, positioning ring 12 is sticked into the outer wall of inner sleeve 11.

Detachable joint for plastic tube shown in Figure 2 comprises that opening end is provided with diameter greater than the outer sleeve 4 and the seal ring 3 that is contained in expanded bore of the expanded bore in inner aperture, has been threaded connection a pressure ring 2 on the port of the expanded bore of outer sleeve 4; Seal ring 3 is that head end is provided with socket, and end is provided with the bar of plug;

Have a body 1 to be inserted in outer sleeve 4, seal ring 3 is crimped on outer sleeve 4, between body 1 and pressure ring 2.

Long service time when joint for plastic tube, seal ring 3 breakages of the inside cause joint for plastic tube to leak when needing repairing, and only need pressure ring 2 is screwed out outer sleeve 4, change old seal ring 3 with Xinmi City's seal 3, as figure

Shown in 6, then pressure ring 2 is screwed in outer sleeves 4 and compresses Xinmi City's seal 3 get final product.

This detachable joint for plastic tube is mainly used in the connection between plastic tube, but according to structure and the design of detachable joint for plastic tube of the present utility model, this joint is not limited to plastic tube, also can be used on pipe that other material such as metal makes.
