The sealing component 3 also includes a plurality of silicon A plurality of silicone anti-skid pads 303 are vertically and equidistantly distributed on the outer wall of the sealing plug 302. The number of silicone anti-skid pads 303 is consistent with that of the fixing grooves 202, and they correspond one to one. The sealing assembly 3 also includes a built-in silicone filling column 305 that penetrates and is fixedly connected to the inner wall of the sealing plug 302. The bottom end of the built-in silicone filling column 305 is fixedly connected to a silicone sealing pad 304. The top outer wall of the silicone sealing pad 304 is fixedly connected to the bottom end of the sealing plug 302. When the carbon fiber hydrogen storage bottle body 1 is sealed, The silicone sealing pad 304 at the bottom of the sealing plug 302 presses against the top end of the carbon fiber hydrogen storage bottle body 1 and seals the mouth of the carbon fiber hydrogen storage bottle body 1 to reduce the gap near the mouth of the carbon fiber hydrogen storage bottle body 1. At the same time, the silicone anti-slip pad 303 on the outer wall of the sealing plug 302 is engaged with the sealing plug 302 to increase the friction after the sealing plug 302 is fixed, and at the same time increase the sealing performance of the sealing plug 302.

[0028] The reinforcement component 5 includes a cavity opened on the outer wall of the threaded cover 301, a sliding rod 501 is fixedly connected to the inner wall of the cavity, a pressing sleeve 502 is fixedly connected to the top of the sliding rod 501, the reinforcement component 5 also includes a spring 503 sleeved on the outer wall of the sliding rod 501, the bottom end of the spring 503 is fixedly connected to the inner wall of the cavity, the top of the spring 503 is fixedly connected to the bottom end of the pressing sleeve 502, the reinforcement component 5 also includes a fixed seat 504 fixedly connected to the outer wall of the bottom end of the threaded inlet 201, a snap-fitting opening 505 is opened through the inner wall at the center of the fixing seat 504, the inner wall of the snap-fitting opening 505 is snap-fitted with the pressing sleeve 502, a sliding groove 506 is opened on the outer wall of the left end of the fixing seat 504, and the sliding groove 506 is opened on the outer wall of the left end of the fixing seat 504. The movable groove 506 is slidably connected to the head of the pressing sleeve 502. When the pressing sleeve 502 rotates to the inside, the pressing sleeve 502 is squeezed by the inner wall of the top of the sliding groove 506 and moves toward the bottom end of the cavity. At the same time, the pressing sleeve 502 moves toward the inside of the cavity on the sliding rod 501 and squeezes the spring 503, so that the spring 503 is under pressure and begins to compress its own volume. When the pressing sleeve 502 continues to slide to the position of the engaging opening 505, the head of the pressing sleeve 502 loses the pressure of the inner wall of the sliding groove 506. At the same time, the spring 503 loses the pressure, begins to restore its elasticity and drives it to move in the opposite direction with the pressing sleeve 502, so that the pressing sleeve 502 is engaged inside the engaging opening 505.

When the threaded cover 301 moves to the engaging opening 505, the head of the fixing seat 504 loses the pressure constraint and moves in the opposite direction under the elastic force of the spring 503, thereby engaging with the inside of the engaging opening 505. At this time, the threaded cover 301 and the outer wall of the threaded inlet 201 are fixed by threads. When the user needs to use it, the carbon fiber engaging cover 403 is spirally rotated to separate the threaded sealing plug 402 from the discharge port 401, and then the hard gas supply pipe is inserted into and penetrates the built-in silicone filling column 305 inside the sealing plug 302, so that the gas supply pipe enters the inside of the carbon fiber hydrogen storage bottle body 1 and is connected, thereby supplying gas.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
