Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0025] Example 1

[0026] This utility model provides, for example Figures 1-7 As shown, a leak-proof device for transporting hazardous chemicals includes a support frame 1, a chemical transport tank 2 mounted on the surface of the support frame 1, a discharge pipe 3 mounted on the side of the chemical transport tank 2, a sealing groove 4 formed on the end face of the discharge pipe 3, a sealing gasket 5 mounted on the end face of the sealing groove 4, a threaded ring 6 mounted on the surface of the discharge pipe 3, a cavity 7 formed on the surface of the threaded ring 6, and sealing oil 8 injected into the cavity 7; a sealing pipe 9, a sealing plate 10 mounted on the surface of the sealing pipe 9, a base plate 11 mounted on the surface of the sealing plate 10, and a positioning groove 12 formed on the surface of the base plate 11;

[0027] First, the sealing plate 10 is screwed into the threaded ring 6. The threaded ring 6 has a cavity 7. When the sealing tube 9 is fixed in the discharge pipe 3 in conjunction with the threaded ring 6, the discharge pipe 3 can be sealed by squeezing the sealing gasket 5 at one end of the sealing tube 9. On the other hand, the sealing oil 8 is injected into the cavity 7, which can further improve the sealing of the discharge pipe 3 and improve safety.

[0028] Example 2: Figure 1 , Figure 2 and Figures 5-7As shown in the figure, in order to facilitate the sealing of the discharge pipe 3, a sealing pipe 9 is provided. The sealing gasket 5 is fixedly connected to the surface of the sealing groove 4. The sealing gasket 5 is in the shape of an annular plate structure. The sealing plate 10 is in the shape of an annular plate structure. The sealing plate 10 is screwed into the threaded ring 6. An injection hole 13 is formed on the side surface of the sealing plate 10. A sealing plug 14 is arranged in the injection hole 13. A placement groove 19 is formed on the surface of the sealing pipe 9. An auxiliary gasket 20 is arranged in the placement groove 19. The placement groove 19 is in the shape of an annular plate structure;

[0029] More specifically, during use, first, the sealing plate 10 can be screwed into the threaded ring 6. Then, the sealing gasket 5 can be extruded through the screwing displacement. Then, the sealing plug 14 can be opened, and sealing oil 8 can be injected into the cavity 7 through the injection hole 13. Then, the injection hole 13 is sealed by the sealing plug 14. The auxiliary gasket 20 in the placement groove 19 contacts the inner wall of the discharge pipe 3 to increase the sealing performance. Thus, the sealing effect of the sealing pipe 9 on the discharge pipe 3 can be enhanced by the sealing oil 8 and the auxiliary gasket 20 to avoid leakage problems.

[0030] Embodiment 3: As Figure 3 and Figure 4 shown in the figure, in order to improve the connection stability of the sealing pipe 9, a fixing plate 15 is provided. The fixing plate 15 is arranged on the side surface of the threaded ring 6. The fixing plate is in the shape of a "C"-shaped plate structure. A vertical rod 16 is arranged on the surface of the fixing plate 15. A limiting spring 17 is sleeved on the surface of the vertical rod 16. A limiting plate 18 is sleeved on the surface of the vertical rod 16. The limiting plate 18 is in the shape of an "L"-shaped plate structure. One end of the limiting plate 18 is inserted into the positioning groove 12. One end of the limiting spring 17 is fixedly connected to the bottom of the limiting plate 18. The other end of the limiting spring 17 is fixedly connected to the surface of the fixing plate 15;

[0031] More specifically, first, the limiting plate 18 is pulled upward along the vertical rod 16. Then, the sealing pipe 9 can be screwed to a suitable position. Then, the limiting plate 18 is released. The limiting plate 18 can be reset by the pulling force of the limiting spring 17, so that one end of the limiting plate 18 is inserted into the positioning groove 12. Thus, the sealing pipe 9 can be fixed, avoiding the problem that the screwing of the sealing plate 10 becomes loose due to the vibration generated during transportation. The limiting spring 17 also avoids the problem that the limiting plate 18 will displace randomly due to its own pulling force.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
