The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
A variable-caliber adapter tube is shown in figure 1 and comprises a bearing tube 1 and two annular elastic bag structures;
two annular elastic bag structural symmetry set up inside bearing pipe 1, are equipped with the clearance between two annular elastic bag structures, and two annular elastic bag structures all are used for realizing sealing putting into the mouth of pipe that bears in pipe 1, bear pipe 1 and be ordinary material hard tube, and the material is hard plastic tube, PVC pipe or tubular metal resonator, and in this embodiment, bear 1 material of pipe and be hard plastic tube.
Annular elastic bag structure includes elastic bag 2 and bag interface 3, bag interface 3 sets up on elastic bag 2, bag interface 3 can dismantle with carrier tube 1 and be connected, be used for gas or liquid to fill in elastic bag 2, in this embodiment, elastic bag 2 and carrier tube 1's inner wall veneer, elastic bag 2 can change the size according to the pressure height of inside gas or liquid of filling, bag interface 3 and carrier tube 1 threaded connection, elastic bag 2 is the capsule bag, elastic bag 2's outer wall is smooth surface, carrier tube 1 is longer than two elastic bag 2 a little, guarantee that elastic bag 2 is inside carrier tube 1 all the time.
In this embodiment, the bladder port 3 is a one-way valve port.
When elastic bag 2 is not filled with gas or liquid, elastic bag 2 is the round platform type structure, and 2 one end of elastic bag are the free end, and 2 other ends of elastic bag are connected with 1 inner wall of carrier tube, and the elastic bag 2 of two annular elastic bag structures is relative with the tip of 1 inner wall of carrier tube connection, and bag interface 3 sets up the tip of being connected at elastic bag 2 and carrier tube 1 inner wall.
When the adapter tube is used, a first tube opening 6 is inserted into one elastic bag 2, a second tube opening 9 is inserted into the other elastic bag 2, then the interior of the elastic bag 2 is pressurized through the bag opening plug, when one elastic bag 2 expands to fill the space between the first tube opening 6 and the bearing tube 1, the other elastic bag 2 expands to fill the space between the second tube opening 8 and the bearing tube 1, in the embodiment, when the internal pressure of the elastic bag 2 reaches 4MPa, the pressurization is stopped, and the adapter tube is combined with the first tube opening 6 and the second tube opening 8; through pressurizing two elastic bag 2, make elastic bag 2 inflation press from both sides two mouths of pipe tightly to reach the purpose of sealing connection, can realize the mouth of pipe connection of different pipe diameters through the volume of pressurizing of adjusting bag filler 7.
