Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a diagram illustrating the gas injection operation state of the present invention;
FIG. 3 is a perspective view of the plugging mechanism of the present invention;
fig. 4 is a top view of the plugging mechanism of the present invention.
The specific implementation mode is as follows:
referring to the drawings, the present invention specifically adopts the following embodiments: the gas injection bottle comprises a bottle body 1, wherein a gas injection pipe 4 is arranged on the bottle body 1, the bottom end of the gas injection pipe 4 is arranged in the bottle body 1, a plugging mechanism 2 is arranged at the bottom end of the gas injection pipe 4, the plugging mechanism 2 comprises a bottom plate 23, a side plate 25, an arc-shaped sealing cylinder 21 and a sealing plug 24, the bottom plate 23 and the side plate 25 are integrally manufactured, the outer edge of the bottom plate 23 is vertically and fixedly connected with the arc-shaped sealing cylinder 21, the arc-shaped sealing cylinder 21 surrounds the outer wall of the gas injection pipe 4, the center of the top end of the bottom plate 23 is provided with the sealing plug 24, and the sealing plug 24 is inserted into a port at the bottom end of the gas injection pipe 4; the top end of the arc-shaped sealing cylinder 21 is connected with the outer wall of the gas injection pipe 4 through a pin 22; the side plate 25 is connected with the inner wall of the bottle body 1 through two extension springs 3. The outer wall of the top end of the gas injection pipe 4 is provided with an external thread, a plugging cap 5 is sleeved outside the gas injection pipe 4, and the internal thread of the plugging cap 5 is connected with the external thread of the gas injection pipe 4 through a thread. The top in the plugging cap 5 is provided with a leakage-proof plug 6, and the leakage-proof plug 6 is connected with the port at the top end of the gas injection pipe 4 in an interference fit manner.
When the stable leakage-proof hydrogen cylinder is used, the sealing cap 5 is screwed on the top end of the gas injection pipe 4 through threads, the leakage-proof plug 6 in the sealing cap 5 is plugged into the top end port of the gas injection pipe 4 and is connected in an interference fit manner, so that hydrogen in the cylinder body 1 can be prevented from leaking, and the effect of preventing leakage during storage is achieved.
