Background
When a certain type of part needs to seal each hole when performing a gas pressure test, since the part has through holes in a plurality of direction angles and needs to be sealed, if a sealing clamp is designed, the design of the clamp becomes complicated and difficult in consideration of the sealing of all holes on the clamp. If the existing sealing plug is designed, a common sealing device is sealed by virtue of the expansion of the outer side of the plug and the friction force of the extrusion of the inner side wall of the part. When the pressure of the inner cavity is too high, insufficient friction force between the plug and the inner side wall of the part can be caused, and the plug is punched out. It would be desirable to design a device for simple and quick sealing of an orifice while simultaneously enabling self-locking of the seal under pressure in the lumen.

Detailed Description
In fig. 1, the invention comprises a T-shaped connecting block 1, a conical ventilation rod (i.e. working rod) 3 and a sleeve 5. The side part and the lower part of the T-shaped connecting block are respectively provided with a threaded hole, and the two holes are communicated for ventilation. The side screw hole is connected with a pressure indicator 8 through a pipe joint 7, and the pressure indicator 8 is connected with an air compressor through the pipe joint 7 and a ventilation hose 9. The lower threaded hole is connected with the external thread of the conical ventilation rod 3 and is locked by the nut 2. The middle of the conical ventilation rod 3 is drilled through, and the lower part of the conical ventilation rod is provided with a working plug, wherein the working plug comprises a round table part and a cylindrical part connected with the round table part. The sleeve 5 is a stepped sleeve, the lower step is tightly matched with the rubber sealing sleeve, the outer diameter of the matched sealing rubber sealing sleeve and the middle step of the sleeve are slightly smaller than the diameter of the orifice of the part to be sealed, and the upper step is used for being matched with the T-shaped connecting block 1 to press the spring 4. The sum of the length of the sealing rubber sleeve 6 and the length between the sealing rubber sleeve and the sleeve 5 is larger than the depth of a part hole to be sealed, and the diameter of the outer circle is slightly smaller than the diameter of a part hole when the outer circle is not deformed. The conical ventilation rod 3 passes through the sleeve inner hole and the spring 4 and then is matched with the threaded hole at the lower part of the T-shaped connecting block, and is locked by the nut 2. The diameter of the spring 4 is larger than the outer diameter of the T-shaped screw 1 and the central through hole of the rubber sealing sleeve 3 so as to ensure free expansion, and the length of the spring 4 is longer than the distance from the T-shaped end of the T-shaped screw 1 to the step end face of the rubber sealing sleeve 3 after the working plug is screwed. In a free state, the spring is in a compressed state, and the working plug conical surface at the lower end of the conical ventilation rod 3 is pushed by the restoring force of the spring to prop up the inner hole at the lower end of the sealing rubber sleeve 6 so as to deform, and the outer maximum diameter of the deformed rubber sleeve is larger than the diameter of the hole of the part to be sealed.
When the device is in a to-be-sealed state, as shown in figure 2, the device is propped against the upper step surface of the sleeve 5, the conical ventilation rod of the T-shaped connecting block meter is pushed to compress the spring, the inner hole of the sealing rubber sleeve 6 is separated from the conical surface of the conical ventilation rod 3, and the sealing rubber sleeve is placed into the part hole under the condition of no deformation until the lower end of the sealing rubber sleeve exceeds the inner end surface of the part hole.
When in a sealing state, as shown in figures 3 and 4, the T-shaped connecting block 1 is loosened, the compression restoring force of the spring pushes the conical ventilation rod, the conical surface of the conical ventilation rod props up the inner hole of the sealing rubber sleeve 6 to expand and deform outwards until the outer maximum diameter is larger than the diameter of the hole of the part to be sealed, and the deformed port of the sealing rubber sleeve clamps the inner end surface of the hole of the part, so that the sealing effect is achieved. At the moment, the inner cavity of the part can be pressurized according to the appointed requirement, the conical ventilation rod 3 is pushed by the inner cavity pressure to continuously squeeze the sealing rubber sleeve 6, so that the sealing effect is enhanced, and the sealing is tighter when the pressure is larger.
When the sealing state is canceled, the pressurizing to the inner cavity of the part is stopped, the upper step surface of the sleeve 5 is propped against, the conical ventilation rod of the T-shaped connecting block meter is pushed to compress the spring, the inner hole of the sealing rubber sleeve 6 is separated from the conical surface of the conical ventilation rod 3, and the sealing plug can be taken out.
