Description

The rapid pipe joint of the outer silk of plastics
Technical field
The utility model relates to a kind of joint of plastic material tubing.
Background technique
The joint that uses during plastic material tubing connects at present uses hot melting way to connect more, and execution conditions require high, need hot melt mould and construction power supply, and melted material must be identical.Tubing and nipple must guarantee anhydrous, no spot when more crucial was construction, otherwise influenced quality of connection.
Summary of the invention
The purpose of this utility model is that the rapid pipe joint of the outer silk of a kind of plastics will be provided, and this joint construction does not need hot melt mould and construction power supply easily, and quality of connection is reliable.
The purpose of this utility model is achieved in that this joint comprises main body and pressure cap, one end of main body is provided with outside thread, the other end inwall of main body is provided with internal thread, be provided with step in the main body, the pressure cap outer wall is provided with outside thread, pressure cap is positioned at the main body the other end, and the pressure cap outside thread matches with the main body internal thread, and seal ring, pad, snap close are between the step and pressure cap interior edge face of main body.
The utility model is easy for installation, does not need that instrument is auxiliary can realize being connected of tubing and joint fast, is applicable to various plastic tubes, no materials limitations.Lower to the construction environment requirement, be applicable to that the plastic pipe under the various construction environments connects.
Description of drawings
Fig. 1 is an embodiment's of the utility model a structural representation.
1. main bodys among the figure, 2. seal ring, 3. pad, 4. snap close, 5. pressure cap, 6. tubing.
Embodiment
In Fig. 1, the left end of main body 1 is injected with English system 1/2 outside thread of a standard, and the right-hand member inwall of main body 1 is provided with internal thread, be provided with step in the main body 1, pressure cap 5 outer walls are provided with outside thread, and pressure cap 5 is positioned at main body 1 right-hand member, and pressure cap 5 outside threads match with main body 1 internal thread.Seal ring 2, pad 3, snap close 4 are between the step and pressure cap 5 interior edge faces of main body 1.
Main body 1, pad 3 and pressure cap 5 use food grade plastic to be raw material, through the injection moulding once-through; Seal ring 2 adopts the Nitrile Rubber material, and snap close 4 adopts stainless steel.Main body 1 and accessory all meet hygienic requirements, and be nontoxic, pollution-free.
During use, seal ring 2, pad 3, snap close 4, pressure cap 5 are put into main body 1 successively and screwed pressure cap 5.Tubing successively can be in place by pressure cap 5, snap close 4, pad 3 and seal ring 2 after insertion.Pin tubing by snap close 4 it is got loose, seal by seal ring 2 and make joint non-leakage, compress seal ring 2 by pressure cap 5 and make joint performance stable with snap close 4.
