Summary of the invention
This utility model mainly solves the technical problem existing for prior art, thus provides a kind of bellows connecting device of ether air anesthesia unit.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of bellows connecting device of ether air anesthesia unit, the bellows connecting device of described ether air anesthesia unit comprises a connection spiral shell head, described connection spiral shell head comprises a rear sleeve and an anterior cannula, a hexagonal swivel nut is provided with between described anterior cannula and described rear sleeve, described anterior cannula is provided with a positioning screw cap, the inwall of described rear sleeve is provided with rear connecting thread, the outer wall of described anterior cannula is provided with outer connecting thread, the bottom of described rear sleeve is provided with first closure gasket groove be obliquely installed of an annular, a dismountable sealed circular ring is provided with in described rear sleeve, one isolation pad and a locking spiral shell head, described locking spiral shell head comprises a spiral shell head cylindrical shell and a hexagonal spiral shell head, described spiral shell head cylindrical shell matches with described rear connecting thread.
As this utility model preferred embodiment, the second sealing ring be obliquely installed that the bottom of described sealed circular ring is provided with an annular is dashed forward, and the second described sealing ring is dashed forward and to be matched with the first described closure gasket groove.
As this utility model preferred embodiment, described sealed circular ring is that silicone rubber is one-body molded.
The advantage of the bellows connecting device of ether air anesthesia unit of the present utility model is: when user screws locking spiral shell head, isolation pad crush seal annulus, second sealing ring is dashed forward and the first closure gasket groove close contact, substantially increase the air-tightness of the connection of this bellows connecting device, structure is simple, practical, effectively improve the reliability of anesthetic machine bellows.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
This utility model provides a kind of bellows connecting device of ether air anesthesia unit.
As shown in Figures 1 to 6, the bellows connecting device 1 of ether air anesthesia unit of the present utility model comprises a connection spiral shell head 2, this connection spiral shell head 2 comprises rear sleeve 21 and an anterior cannula 22, a hexagonal swivel nut 26 is provided with between this anterior cannula 22 and this rear sleeve 21, this anterior cannula 22 is provided with a positioning screw cap 3, the inwall of this rear sleeve 21 is provided with rear connecting thread 23, the outer wall of this anterior cannula 22 is provided with outer connecting thread 24, the bottom of this rear sleeve 21 is provided with first closure gasket groove 25 be obliquely installed of an annular, a dismountable sealed circular ring 4 is provided with in this rear sleeve 21, one isolation pad 5 and a locking spiral shell head 6, this locking spiral shell head 6 comprises spiral shell head cylindrical shell 61 and a hexagonal spiral shell head 62, this spiral shell head cylindrical shell 61 matches with rear connecting thread 23.
The bottom of sealing annulus 4 is provided with second sealing ring be obliquely installed prominent 41 of an annular, and this second sealing ring prominent 41 matches with this first closure gasket groove 25.
Sealing annulus 4 is that silicone rubber is one-body molded.
During use, cooperatively interacting of the first closure gasket groove 25 utilizing the second sealing ring of sealed circular ring 4 to dash forward bottom 41 and rear sleeve 21, because sealed circular ring 4 is that silicone rubber is one-body molded, when user screws locking spiral shell head 6, isolation pad 5 crush seal annulus 4, makes the second sealing ring prominent 41 and the first closure gasket groove 25 close contact, substantially increase the air-tightness of the connection of this bellows connecting device 1, structure is simple, practical, effectively improves the reliability of anesthetic machine bellows.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
