Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic view of the convex bottom of the present invention just contacting with the upper end face of the gas cylinder.
Fig. 3 is a schematic structural view of the sealing ring of the present invention during compression.
In the figure: 1. a seal ring body; 2. an arc groove; 3. salient points; 4. an annular projection; 5. a shoulder protrusion; 6. a convex bottom; 7. a gas cylinder; 71. a one-way valve; 8. a gas cylinder connector; 81. and (4) a thimble.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 3, a sealing ring with better sealing compressibility is assembled into a gas cylinder connector 8 to seal a gas cylinder 7 and the gas cylinder connector 8, when the gas cylinder 7 is connected to the gas cylinder connector 8, the sealing ring contacts with the upper end surface of the gas cylinder 7 first, and a thimble 81 on the gas cylinder connector 8 contacts with a check valve 71 on the gas cylinder 7, so that the gas cylinder 7 and the gas cylinder connector 8 are sealed first and then the check valve 71 of the gas cylinder 7 is opened.
The sealing washer includes sealing washer body 1, 1 inner wall middle part position of sealing washer body is equipped with circular arc recess 2, and wherein this middle part position does not refer in particular to the most middle position of sealing washer body 1, but indicates the position between 1 topmost and the bottommost of sealing washer body, and sealing washer body 1 is when pressurized, and the both ends that sealing washer body 1 corresponds circular arc recess 2 can be to circular arc recess 2's direction extrusion, the utility model discloses a set up circular arc recess 2 at 1 inner circle of sealing washer body, utilize circular arc recess 2's space to increase the compressibility of sealing washer, and then be convenient for the user to twist the gas cylinder and connect 8 in order to reach the purpose that sealed gas cylinder 7 and gas cylinder connect 8, and then solved and twisted the gas cylinder and connect 8 and have when having with the compression seal circle and twist hard problem soon.
