Specific implementation mode：
Embodiment：See shown in Fig. 1 to 3, a kind of rubber seal plug of airtight test, including vertical outer tube 1, housing
The upper/lower terminal of pipe 1 forms the tensioning sleeve 11 of cone, if forming arterial highway grooving 12 on tensioning sleeve 11, grooving 12 is divided
Tensioning sleeve 11 is in several arc plates, and 1 upper sleeve of outer tube has outer rubber to cover 2, and the upper and lower inner wall of outer rubber set 2, which is pasted, to be fixed
On the outer wall of tensioning sleeve 11, the lower platen 3 of truncated cone-shaped, the middle part of lower platen 3 are plugged in the tensioning sleeve 11 of 1 lower end of outer tube
Vertical interpolation pipe 31 is formed, the upper end of interpolation pipe 31 passes through the top board 4 of truncated cone-shaped to form annular baffle ring 32, baffle ring
It is formed on 32 upper surface and is threadedly coupled seat 33, be threadedly coupled on seat 33 and be bolted with tracheae quick coupling 7；The top board
4 are pressed against on 11 inner wall of tensioning sleeve of 1 upper end of outer tube, and compression spring 6 is plugged on the interpolation pipe 31 of 4 upside of top board, compression spring 6
