Abstract
The utility model relates to a quick expandable sealing of cylinder type connects, including a fixed support, downside gasket, expandable sealing circle, upside gasket, spacing jump ring, quill shaft, little O type circle, big O type circle, the actuating cylinder lid of living, the quill shaft passes through the gas thread to be fixed on the support, the actuating cylinder lid of living is installed on the support, it is equipped with big O type circle to live between actuating cylinder lid and the support, it is equipped with little O type circle to live between actuating cylinder lid and the quill shaft to guarantee the leakproofness of cylinder, supreme downside gasket, expandable sealing circle, upside gasket and the spacing jump ring installed is in proper order down followed to the quill shaft upper end. Compare with traditional sealing joint, this joint sealing is effectual, and sealed fast, a product can be suitable for the product in certain diameter range, and product internal diameter in certain extent need not to change sealing joint when changing, more is favorable to improving production efficiency.
Description
Technical field
This utility model relates to a kind of air-cylinder type rapid expanding seal nipple, it is adaptable to water flowing in cavity, ventilation after the fast sealing of cylindrical cavity, easy to connect and good sealing effect.
Background technology
Existing seal nipple many employings manual machinery formula seals, end surface sealed, this kind of seal nipple troublesome poeration, waste time and energy, sealing effectiveness is undesirable simultaneously, and in order to ensure that seal existing joint adopted extruding, interference seal more, this encapsulating method easily extrudes thus damages product, causes that product rejection rate is higher.
Utility model content
For the defect of existing seal nipple, the purpose of this utility model is in that to provide a kind of air-cylinder type rapid expanding seal nipple, and it is possible not only to fast sealing cylindrical cavity can also be suitable for the product of certain limit diameter.
For reaching above-mentioned purpose, this utility model adopts following technical proposals:
A kind of air-cylinder type rapid expanding seal nipple, including a fixing bearing, downside pad, Expansion sealing circle, upside pad, spacing jump ring, quill shaft, little O, big O, moving cylinder lid, described quill shaft is threadedly secured on bearing by pipe, described moving cylinder lid is arranged on bearing, it is provided with big O between described moving cylinder lid and bearing, it is provided with little O, to ensure the sealing of cylinder between described moving cylinder lid and quill shaft；Described quill shaft upper end is sequentially installed with downside pad, Expansion sealing circle, upside pad and spacing jump ring from bottom to up.
This utility model compared with prior art, has following apparent substantive distinguishing features and progress:
Compared with conventional seals joint, this joint sealing is effective, sealing speed is fast, complete to seal by cylinder extrusion expansion sealed ring deformation, deflection is less on sealing effectiveness impact, and therefore this quick seal coupling adapts to cavity diameter relatively extensively, and a kind of product can be suitable for the product within the scope of certain diameter, without changing seal nipple when product internal diameter changes within the specific limits, it is more beneficial for improving production efficiency.

Detailed description of the invention
Details are as follows in conjunction with accompanying drawing for preferred embodiment of the present utility model:
As shown in Figure 1 to Figure 3, a kind of air-cylinder type rapid expanding seal nipple, including fixing bearing 1, downside pad 2, Expansion sealing circle 3, upside pad 4, spacing jump ring 5, quill shaft 6, little O 7, big O 8, a moving cylinder lid 9, described quill shaft 6 is threadedly secured on bearing 1 by pipe, described moving cylinder lid 9 is arranged on bearing 1, big O 8 it is provided with between described moving cylinder lid 9 and bearing 1, little O 7 it is provided with, to ensure the sealing of cylinder between described moving cylinder lid 9 and quill shaft 6；Described quill shaft 6 upper end is sequentially installed with downside pad 2, Expansion sealing circle 3, upside pad 4 and spacing jump ring 5 from bottom to up.
Using method of the present utility model is:
As shown in Figure 3 and Figure 4, in use, ventilated to inner chamber by A mouth, gas push moving cylinder lid 9 moves upward, Expansion sealing circle 3 between moving cylinder lid 9 extruding upside pad 4 and downside pad 2, Expansion sealing circle 3 is extruded rear diametric(al) and expands, and seals cylindrical cavity, then passes through B mouth to water flowing in cavity, ventilation.
