[0025] Specifically, a T-shaped groove is provided inside the top wall of the first sealing cover 3, and a second piston 13 is engaged in the T-shaped groove. A first sealing gasket 14 is fitted on the outer surface of the discharge pipe 2, and the bottom of the first sealing gasket 14 abuts against the top of the chemical drum 1.
[0026] Please refer to Figure 2 to Figure 3 When sealing the discharge pipe 2, the first sealing cap 3 is fitted onto the discharge pipe 2, and the second piston 13 is inserted into the inside of the discharge pipe 2 to block the discharge pipe 2 and prevent the chemicals from leaking out. The first sealing cap 3 is rotated, and the first sealing cap 3 is threaded to the outer surface of the discharge pipe 2. The bottom of the first sealing cap 3 is tightly attached to the first sealing gasket 14 to prevent the chemicals from leaking out again.
[0027] Specifically, the lead screw 5 is rotatably connected to the inside of the top wall of the chemical drum 1 via a bearing. A second sealing gasket 15 is fitted onto the outer surface of one end of the lead screw 5, and the bottom of the second sealing gasket 15 abuts against the top of the chemical drum 1.
[0028] Please see Figures 2 to 3 The second sealing gasket 15 can prevent chemicals from leaking out at the second sealing cap 4 after the chemical drum 1 is tipped over.
[0029] Specifically, a guide rod 16 is provided on the inner top wall of the chemical drum 1, and a movable plate 6 is sleeved on the outer surface of the guide rod 16.
[0030] Please refer to Figure 2 to Figure 3 The guide rod 16 limits the movement of the movable plate 6, guiding the movable plate 6 to move upward or downward.
[0031] Specifically, there are two second through holes. The base 9 has two first screw holes inside the front and rear walls. A connecting plate 17 is sleeved on the outer surface of one end of the support rod 10. The connecting plate 17 has a second screw hole inside the other end. A bolt 18 adapted to the inner diameter of the second screw hole is installed inside the second screw hole.
[0032] Please refer to Figure 4 to Figure 5 With the cooperation of the second through hole and the first screw hole, the support rod 10 can drive the roller 12 to move up and down, and the bolt 18 can be fixed in the first screw hole to limit and fix the connecting plate 17.
[0033] Specifically, a sliding groove is provided inside the base 9 near the rear side, and a storage box 19 is engaged in the sliding groove. A Π-shaped groove is provided inside the rear wall of the base 9, and a push rod 20 is engaged in the Π-shaped groove. A third through hole is provided inside the rear wall of the storage box 19, and the inner diameter of the third push rod 20 is slightly larger than the diameter of the push rod 20.
[0034] Please refer to Figure 4 to Figure 5 A funnel can be placed in the storage box 19. When pouring out chemicals, the funnel is threaded to the outer surface of the discharge pipe 2. The push rod 20 can move in the Π-shaped groove and enter the third through hole inside the rear wall of the storage box 19 to limit the storage box 19 and prevent it from sliding out of the groove during the movement of the chemical drum 1.
[0035] During use, when emptying the chemicals inside the chemical drum 1, rotate both first sealing caps 3 and remove the second piston 13. Simultaneously rotate the second sealing cap 4, which drives the lead screw 5 to rotate. The lead screw 5 drives the moving plate 6, which is connected to the outer surface of the lead screw 5. The moving plate 6 moves downward along the direction of the guide rod 16 and drives the first piston 7. The first piston 7 no longer blocks the discharge pipe 2. Connect the funnel threaded to the outer surface of the discharge pipe 2. Then, grasp the handle 8, tilt the chemical drum 1, and pour out the chemicals. When emptying the chemicals from the drum, air can escape from the other side. The discharge pipe 2 enters the pouring bucket, thereby balancing the air pressure inside and outside the bucket and accelerating the pouring efficiency. After pouring is complete, the funnel is removed, and the first sealing cap 3 is threaded onto the outer surface of the discharge pipe until the bottom of the first sealing cap 3 abuts against the first sealing gasket 14. At the same time, the second piston 13 is engaged inside the discharge pipe. The second sealing cap 4 is rotated, which drives the lead screw 5 to rotate. The lead screw 5 drives the moving plate 6, which is connected to the outer surface of the lead screw 5. The moving plate 6 moves upward along the direction of the guide rod 16 and drives the first piston 7. The first piston 7 blocks the inner wall of the discharge pipe 2. The resealable design prevents chemicals from leaking out of the chemical drum 1 when it is tipped over. When transporting chemicals between laboratories, the weight of the chemicals in the drums makes individual handling difficult. Therefore, when moving the chemical drum 1, first lift it upwards and use a pad or other hard object to support it. Then, turn bolt 18 until it disengages from the first screw hole at the top. Next, turn the connecting plate 17 and pull the support rod 10, disengaging it from the second through hole inside the base 9. Push the support rod 10 downwards, causing it to move downwards. The plate 11 and roller 12 move downwards until the bolt 18 is aligned with another first screw hole. Then, the support plate 11 is pushed so that the support rod 10 enters another second through hole and the bolt 18 enters another first screw hole. The bolt 18 is rotated so that it limits and fixes the connection. Finally, the pad or hard object is removed, the roller 12 contacts the ground, and the chemical drum 1 is pushed to another location or laboratory. This achieves the effect of effectively preventing chemical leakage after the chemical drum is tipped over and facilitating the movement of the chemical drum.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
