For achieving the above object, this utility model is by the following technical solutions:
A kind of safety type Pneumatic quick connector；Including a maincenter and the overcoat of outside suit thereof；The positioning end of described maincenter is provided with lock pin cavity volume, and binding end is provided with spool cavity volume, is provided with location barrier between lock pin cavity volume and spool cavity volume；The binding end of described maincenter connects a hollow nut, is sequentially provided with sealing gasket, spool and in order to support the valve core spring of this valve core reset between described barrier and described nut；What the positioning end outer wall of described maincenter was symmetrical is provided with breach, is respectively provided with an alignment pin in breach, and this two alignment pin protrudes from the part of described maincenter inwall for fixing lock pin；Described overcoat is provided with lobe near the positioning end inwall of described maincenter, is sequentially provided with outer casing spring and for the back-up ring being maintained in described breach by described alignment pin between positioning table and this lobe of the binding end outer wall of described maincenter；The binding end set of described maincenter is equiped with and limits the stop collar that described overcoat moves to described nut direction；Described central location end outer wall is provided with and limits the collar that described overcoat outwards comes off.
Further, described stop collar is threaded on described maincenter.
Further, described maincenter uses fine thread to be connected with described nut.
Further, described sealing gasket is rubbery flat gasket.
Further, described sealing gasket is fluorubber plain cushion.
Further, described lobe is the plane fitted with described back-up ring towards the one side of described maincenter binding end.
This utility model having the beneficial effect that compared with prior art
This utility model reasonable in design, is provided with on maincenter and limits the stop collar that overcoat is movable, keeps away lock pin and goes out joint and cause danger, in order to avoid injury behaviour personnel, it is achieved while joint quickly connects and dismantles, use more safe and reliable.When lock pin extracted by needs, only need rotary spacing set, make stop collar screw to maincenter binding end, then pull overcoat, very convenient, control easily.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
A kind of safety type Pneumatic quick connector as shown in Figure 1 to Figure 3；Including a maincenter 1 and the overcoat 14 of outside suit thereof；The positioning end 2 of described maincenter 1 is provided with lock pin cavity volume 3, and binding end 4 is provided with spool cavity volume 5, is provided with location barrier 6 between lock pin cavity volume 3 and spool cavity volume 5；The binding end 4 of described maincenter 1 connects a hollow nut 7, be sequentially provided with between described barrier 6 and described nut 7 sealing gasket 8, spool 9 and in order to support this spool 9 reset valve core spring 10；What positioning end 2 outer wall of described maincenter 1 was symmetrical is provided with breach 11, is respectively provided with an alignment pin 12 in breach 11, and this two alignment pin 12 protrudes from the part of described maincenter 1 inwall for fixing lock pin 13；Described overcoat 14 is provided with lobe 15 near positioning end 2 inwall of described maincenter 1, is sequentially provided with outer casing spring 17 and for the back-up ring 18 being maintained in described breach 11 by described alignment pin 12 between positioning table 16 and this lobe 15 of binding end 4 outer wall of described maincenter 1；Binding end 4 set of described maincenter 1 is equiped with and limits the stop collar 19 that described overcoat 14 moves to described nut 7 direction；Described maincenter 1 positioning end 2 outer wall is provided with and limits the collar 20 that described overcoat 14 outwards comes off.
Overcoat 14 is provided with the anti-skidding lines of roll forming, more easily can grip when mounting or dismounting snap joint and during grafting lock pin 13.
Wherein, described stop collar 19 is threaded on described maincenter 1.It is completely embedded, connects cooperation reliable and stable, during connecting core insert 13, can screw as required and be adjusted to correct position, for ensureing that lock pin 13 the most in use comes off, can be after inserting lock pin 13, stop collar 19 is tightened, propping up overcoat 14, make overcoat 14 one end be positioned by collar 20, the other end is positioned by this stop collar 19, overcoat 14 will not be movable, therefore, effectively prevent lock pin after overcoat gets loose and go out the danger of joint, use safer.
Wherein, described maincenter 1 uses fine thread to be connected with described nut 7.It is completely embedded, connects cooperation reliable and stable.
Wherein, described sealing gasket 8 is rubbery flat gasket.It is firm to seal, it is ensured that sealing during spool Guan Bi.If using in the environment of temperature is higher, the most described preferred fluorubber plain cushion of sealing gasket 10, can use the most for a long time, being hardly damaged.
Wherein, described lobe 15 towards the one side of described maincenter 1 binding end is and the plane of described back-up ring 18 laminating.Can be limited by the back-up ring 18 being fitted in the plane of lobe 15 when alignment pin moves outside breach 11, not come off out, it is ensured that the jump ring reliable and stable with lock pin 13.
This utility model reasonable in design, is provided with the stop collar 19 limiting overcoat 14 activity on maincenter 1, keeps away lock pin 14 and goes out joint and cause danger, in order to avoid injury behaviour personnel, it is achieved while joint quickly connects and dismantles, use more safe and reliable.When lock pin 13 extracted by needs, only need rotary spacing set 19, make stop collar 19 screw to maincenter binding end, then pull overcoat 14, very convenient.
The above is only better embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model patent claim or modification, all it is included in this utility model patent claim.
