[0039] Working principle: When in use, first place a fire extinguisher bottle in the first placement tube 10, the test fire extinguisher bottle is in a sealed state, start the first motor 30 to drive the reciprocating screw rod 5 to rotate, and use the threaded fit between the reciprocating screw rod 5 and the moving seat 6 to drive the moving seat 6, the first placement tube 10 and the second placement tube 11 to move, so that the first placement tube 10 with the fire extinguisher bottle is moved to the top of the test box 1, at this time, the second placement tube 11 is located on the side of the test box 1, and the first motor 30 is stopped, and then the electric hydraulic rod 8 is started to drive a sealing plate 9 and the first placement tube 10 to move downward , so that the sealing plate 9 is covered on the top of the test box 1 to seal, the fire extinguisher bottle on the first placement tube 10 is placed in the inner cavity of the test box 1, and at this time, another fire extinguisher bottle to be tested is placed on the second placement tube 11, and then the hydraulic cylinder 23 is started to drive the piston plate 24 to move to the side away from the test box 1, so as to extract air from the inner cavity of the test box 1, and the air pressure detector 14 is used to detect the air pressure in the inner cavity of the test box 1. When the air pressure change range in the test box 1 is small, it means that the gas in the fire extinguisher bottle leaks into the inner cavity of the test box 1, which means that the sealing performance of the fire extinguisher bottle is poor. When the air pressure variation range of the test box 1 is large, it means that there is no extra gas replenishment in the test box 1, which means that the gas in the fire extinguisher bottle has no leakage. When a fire extinguisher bottle is detected to be leaking, the electric push rod 19 is started to drive the sleeve 20 and the marker 21 to move, so that the marker 21 and the end of the fire extinguisher bottle are in contact, and the second motor 17 is started to drive the rotating plate 18, the electric push rod 19, the sleeve 20 and the marker 21 to rotate, and the marker 21 is used to draw a circular mark on the bottle body to identify unqualified products. Finally, the piston plate 24 is reset, and the electric hydraulic rod 8 is started with The movable sealing plate 9 and the first placing tube 10 are moved upward, and the first motor 30 is started again to drive the reciprocating screw 5 to rotate, and the cooperation between the reciprocating screw 5 and the moving seat 6 is used to drive the first placing tube 10 to move to the side of the test box 1, so that the second placing tube 11 is moved to the top of the test box 1, and another set of electric hydraulic rods 8 is used to drive another sealing plate 9 and the second placing tube 11 to extend into the test box 1, so as to perform an airtightness test on another fire extinguisher bottle on the second placing tube 11, and at the same time, the tested fire extinguisher bottle on the first placing tube 10 is taken down, and other fire extinguisher bottles are placed.
