Abstract
The utility model relates to a fast-insertion type joint. The joint comprises a first clip sleeve (2), a double-layer oil seal (3) and a second clip sleeve (4); one end of the first clip sleeve (2) is provided with an opening through which the double-layer oil seal (3) is inserted into the first clip sleeve (2); the second clip sleeve (4) is provided with a groove whose shape is matched with the shape of the end of the first clip sleeve (2) which is provided with the opening; and the end of the first clip sleeve (2) provided with the opening can be sheathed in the groove (4) of the second clip sleeve. The fast-insertion type joint of the utility model has the advantages of improved test efficiency and capability of solving the problem of ageing of a seal ring.
Description
Technical field
The utility model relates to a kind of push-in joint, especially relates to the push-in joint of a kind of double oil seal circle formula, belongs to the instrument fitting field.
Background technology
In dynamic specific surface area analysis instrument, each test port place needs sealing, could guarantee reliability of testing result and accuracy, and the quality of the sealing of test port directly influences measuring accuracy.Major part is used for the nut type interface with quasi-instrument at present, and inside needs to use rubber seal carry out the sealing of gas circuit.Very inconvenient when changing sample, spended time is longer, and long-term use of O-ring seal be easy to wear out, and causes blowby gas path, and then influences test result.
The utility model content
Push-in easily joint when the utility model technical matters to be solved provides a kind of replacing sample.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of push-in joint comprises first cutting ferrule, double-deck oil sealing and second cutting ferrule; One end of said first cutting ferrule is provided with an opening, and said double-deck oil sealing inserts in said first cutting ferrule through said opening; Said second cutting ferrule is provided with a groove, and the shape of said groove matches with the shape of an end of said first cutting ferrule that is provided with opening, and an end that is provided with said first cutting ferrule of opening can be inserted in the groove of said second cutting ferrule.
The beneficial effect of the utility model is: the push-in joint of the utility model has not only improved testing efficiency, has also solved the aging problem of O-ring seal simultaneously.Adopt the double-layer seal form, automatically resilient seal.Improved the leakproofness of test port effectively.It is also quite convenient that sample hose is extracted in insertion.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said push-in joint also comprises nut, and said nut is connected with the other end of said first cutting ferrule.
Adopt the beneficial effect of above-mentioned further scheme to be, said nut can be fixed on first cutting ferrule in the cabinet, plays fixing effect.
Further, said double-deck oil sealing is processed by rubber.
Description of drawings
Fig. 1 is the structural representation of the push-in joint of the utility model;
In the accompanying drawing, the list of parts of each label representative is following:
1, nut, 2, first cutting ferrule, 3, double-deck oil sealing, 4, second cutting ferrule.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of push-in joint, as shown in Figure 1, comprise first cutting ferrule 2, double-deck oil sealing 3 and second cutting ferrule 4; One end of said first cutting ferrule 2 is provided with an opening, and said double-deck oil sealing 3 inserts in said first cutting ferrule 2 through said opening; Said second cutting ferrule 4 is provided with a groove, and the shape of said groove matches with the shape of an end of said first cutting ferrule 2 that is provided with opening, and an end that is provided with said first cutting ferrule 2 of opening can be inserted in the groove of said second cutting ferrule 4.
Said push-in joint also comprises nut 1, and said nut 1 is connected with the other end of said first cutting ferrule 2.
Said double-deck oil sealing 3 is processed by rubber.
The making principle of the push-in joint of the utility model is following:
Be fixed on first cutting ferrule 2 in the cabinet with nut 1 earlier, add double-deck oil sealing 3 at an end opening place of first cutting ferrule 2 then, tighten with second cutting ferrule 4.So just make the push-in joint of what a double-deck oil seal type.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
