Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

See fig. 1-2.

The invention relates to an operation method of a matching sealing structure, which comprises the following steps:

firstly, the external thread body 1 is matched with the expansion body 2;

secondly, the external thread body 1 drives the expansion body 2 to be screwed into a gap between the upper thread body 3 and the lower thread body 4;

thirdly, opening the valve body 5, inputting a pressurized expansion medium 7 into the hollow interior of the expansion body 3 through the input pipe 6, so that the expansion body 3 is tightly attached to the contact surfaces of the upper thread body 3 and the lower thread body 4 after being expanded, closing the valve body 5, and realizing the knob sealing of the upper thread body 3 and the lower thread body 4 with the external thread body 1;

finally, the valve body 5 is opened, and the high-pressure expansion medium 7 is released from the interior of the expansion body 3, so that the screwing-out separation of the external thread body 1, the thread body 3 and the lower thread body 4 can be easily realized; the problem of present screw thread screw difficult division is solved.

The expansion medium 7 may be one of liquid, gel and gas.

The expansion medium 7 is gas, so that the overall weight of the equipment is reduced, and the transportation cost is reduced.

The invention relates to a matching sealing structure, which comprises: the external thread body 1, the expansion body 2, the external thread body 1 and the expansion body 2 are embedded;

the thread comprises an upper thread body 3 and a lower thread body 4, wherein the upper thread body 3 and the lower thread body 4 are distributed at intervals, and an expansion body 2 is positioned in a gap between the upper thread body 3 and the lower thread body 4;

the valve also comprises a valve body 5 and an input pipe 6; the expansion body 2 is internally provided with a hollow sealing body, one end of the input pipe 6 is hermetically communicated with the inside of the expansion body 2, and the other end of the input pipe is communicated with the outside after being communicated with the valve body 5.

The expansion body 2 is made of butyl rubber or natural rubber; ensures that the food can be used after contacting the expansion body 2 and meets the expansibility of the expansion body 2.

The expansion body 2 is trapezoidal; the external thread body 1 is in a trapezoidal shape and is embedded with the expansion body 2, so that the embedding degree is improved.

The cross sections of the upper thread body 3 and the lower thread body 4 are both triangular, so that the contact surfaces of the trapezoidal plane of the expansion body 2 and the triangular upper thread body 3 and lower thread body 4 are planes, and the sealing performance of the contact surfaces of the expansion body 2 and the upper thread body 3 and lower thread body 4 is improved.

The input tube 6 is connected with the lowest part of the expansion body 2, so that the problem that the hole needs to be opened on the bottle cap 9 when the input tube 6 is connected with the middle part of the expansion body 2 is avoided.

The working principle is as follows: firstly, an external thread body 1 fixedly connected with the inner surface of a bottle cap 9 is matched with an expansion body 2;

secondly, the upper thread body 3 and the lower thread body 4 are fixedly arranged on the outer wall of the bottle body 8 at intervals, and the external thread body 1 drives the expansion body 2 to be screwed into a gap between the upper thread body 3 and the lower thread body 4;
