as shown in fig. 3 to 5, a sleeve 44 is screw-coupled to a position of the cylinder 43 away from the hand wheel housing 422, the sleeve 44 is hollow inside, and a step 441 is provided inside the sleeve 44, and an air bag 45 is installed at the step 441, the air bag 45 has a flange (not shown) matching with the step 441, so that the flange is overlapped on the step 441, and then the air bag 45 is fixed inside the sleeve 44 by a fastener, in the present application, a pad 451 may be provided outside the flange of the air bag 45, and the air bag 45 is press-fitted to the sleeve 44 by the pad 451, thereby increasing the stability of the connection of the air bag 45;
meanwhile, when the air bag 45 is installed, the air bag is communicated with the inner cavity of the cylinder body 43, and one end of the air bag 45 far away from the cylinder body 43 protrudes out of the sleeve 44 so as to extend into the interior of the plugging end of the lamp 3;
in summary, in the initial state, the piston 461 is located at one end of the cylinder 43 far from the sleeve 44, and a closed chamber is formed between the piston 461 and the air bag 45, and gas is stored in the closed chamber;
when the plugging operation is required to be performed on the plugging end on the lamp 3, firstly, the mechanical arm 41 is utilized to move the plugging assembly 4 to a designated position, and then the air bag 45 is plugged into the hole of the lamp 3;
at this time, the staff rotates the hand wheel 47 to drive the screw 46 to rotate, so as to drive the piston 461 to move in the direction of the inner sleeve 44 of the cylinder 43, and when the piston 461 moves, the gas in the closed cavity is compressed into the air bag 45, so that the air bag 45 is inflated, and under the action of the inflated air bag 45, the hole of the lamp 3 is completely sealed, so that the air tightness test of the lamp 3 can be further carried out;
in this embodiment, the position of the piston 461 can be adjusted to adjust the size of the air bag 45 during expansion, so as to adapt to holes with different sizes and different shapes, thereby increasing the adaptability of the plugging assembly 4;
meanwhile, for convenience of staff operation, a notch is formed on one side of the hand wheel housing 422, and a knurling pattern is formed on the circumference of the hand wheel 47, so that a sufficient space is available for staff operation, and no slipping occurs during operation.
In the second embodiment, when the holes of the lamp 3 are plugged, because the sizes and depths of the holes are different, for the holes with different sizes, the holes with different depths can be adaptively adjusted through the expansion of the air bags 45, but for the holes with different depths, because the mechanical arms 41 operate according to a specified program, the pushing depths of the mechanical arms 41 are the same, and if the depths of the holes are too shallow, the clamping stagnation of the mechanical arms 41 can be caused;
in order to solve the above problem, as shown in fig. 3-4, an adjusting mechanism is disposed in the closed chamber, and the adjusting mechanism is used for adapting to holes with different depths, specifically:
firstly, in the present embodiment, the piston 461 and the inner wall of the cylinder 43 are both rectangular structures, so that the piston 461 does not rotate in the cylinder 43 through the adaptation of the rectangular structures, thereby realizing the linear reciprocating motion of the piston 461;

because the push rod 411 is in threaded connection with the cylinder 48, when the push rod 411 is blocked, the push rod 411 moves towards the inner cavity of the cylinder 48 and drives the air bag 45 to move together, so that the position of the air bag 45 extending into the hole can be adjusted in a self-adaptive manner according to the depth of the hole on the lamp 3;
in order to enable the push rod 411 to be reset for repeated use, a sliding block 410 is arranged on a bearing at one end of the push rod 411 extending into the barrel 48, meanwhile, a spring 49 is fixedly arranged at one end of the sliding block 410 away from the push rod 411, and one end of the spring 49 away from the sliding block 410 is fixedly arranged with the barrel 48, so that when the push rod 411 is retracted into the barrel 48, the sliding block 410 is pushed to move together and the spring 49 is compressed, and after the resistance of the position of the push rod 411 is eliminated, the spring 49 drives the push rod 411 to reset.
In the third embodiment, when the hole of the lamp 3 is plugged, if the depth of the hole is shallow, the portion where the air bag 45 enters is less, and since the inside of the lamp 3 is filled with the test gas, the test gas has a larger pressure, so that the pressure of the test gas may push the inflated air bag 45 out of the hole (as shown in fig. 7);
in order to solve the above problems, as shown in fig. 3 to 4 and 6, an expansion mechanism 5 is provided on the push rod 411, and the expansion mechanism 5 is located at a position where the push rod 411 is connected to the air bag 45, for expanding the air bag 45 located inside the hole so that the size of the air bag 45 is larger than the size of the inlet of the hole, so that the air bag 45 does not come out of the hole under the pressure of the detected gas, specifically:
the expansion mechanism 5 comprises a connecting column 51 which is arranged on the push rod 411 by a bearing, a chassis 52 is integrally arranged on the connecting column 51, a containing cavity is arranged on one side of the chassis 52 away from the connecting column 51, and a first gear 54 is arranged in the containing cavity, and the first gear 54 and the push rod 411 are fixedly arranged, so that when the push rod 411 rotates, the first gear 54 can synchronously rotate;
meanwhile, a cover plate 53 is also arranged on the push rod 411 in a bearing way, the cover plate 53 is matched with the chassis 52, a circular cavity is formed between the cover plate 53 and the chassis 52, a plurality of groups of second gears 55 are arranged on the position of the cover plate 53, which is positioned in the circular cavity, in a bearing way, the plurality of groups of second gears 55 are uniformly distributed along the circumferential direction by taking the push rod 411 as the center, and the plurality of groups of second gears 55 are meshed with the first gears 54, so that when the first gears 54 rotate, the plurality of groups of second gears 55 can synchronously rotate;
the expansion blades 56 are fixedly arranged on the plurality of groups of second gears 55, so that the expansion blades 56 can rotate together when the second gears 55 rotate, and meanwhile, the expansion blades 56 are accommodated in a circular cavity in an initial state, slowly protrude out of the outer ring of the cover plate 53 in the rotating process and open the air bag 45;
in summary, when the depth of the blocked hole is shallow, the push rod 411 will contact with the blocking object during the pushing process of the air bag 45, so as to drive the push rod 411 to retract and rotate, and this part of the disclosure is described in detail in the second embodiment and is not repeated here;
in the process of retracting and rotating the push rod 411, the first gear 54 is driven to rotate, the first gear 54 drives the plurality of groups of second gears 55 to synchronously rotate under the meshing action, and then the expansion blades 56 are driven to rotate to extend out of the circular cavity, and the air bag 45 positioned in the hole is expanded;
when the air bag 45 is unfolded, the pressure of the test gas in the hole can be better resisted, so that the air bag 45 is prevented from falling out of the hole;
after the air tightness test of the lamp 3 is finished, the plugging assembly 4 starts to retract, the push rod 411 is reset under the action of the spring 49, and the expansion blade 56 is driven to reset through the meshing of the first gear 54 and the second gear 55 when the push rod 411 is reset, so that the next test is convenient.
