[0026] refer to Figures 1 to 2 According to a preferred embodiment of the present invention, a quick-connect fitting assembly for draining residual liquid from a tanker truck is provided. It should be noted that the structure of the quick-connect fitting assembly for draining residual liquid from a tanker truck is as follows: Figure 1 As shown, it is located at one end of the bottom of the outer tanker truck body. It should be noted that one end of the bottom of the outer tanker truck body has a first connecting pipe 100 for drainage. This application is configured to cooperate with the first connecting pipe 100 to define the position of this application.

[0027] Specifically, the quick-connect fitting assembly for draining remaining liquid from the tanker includes a second connecting pipe 10. One end of the second connecting pipe 10 is fixedly connected to the end of the first connecting pipe 100, and the connection method can be welding. It is worth noting that the second connecting pipe 10 has a first connecting portion 11, an extension portion 12, and a second connecting portion 13. The two ends of the extension portion 12 are respectively connected to the first connecting portion 11 and the second connecting portion 13, and the first connecting portion 11, the extension portion 12, and the second connecting portion 13 are formed as a single unit. Furthermore, the structure and dimensions of the first connecting portion 11 and the second connecting portion 13 are identical.

[0028] Furthermore, the second connecting pipe 10 has a first flow hole 101, which passes through the first connecting part 11, the extension part 12 and the second connecting part 13 in sequence. In addition, the top of the extension part 12 also has a protrusion 14, which has a mounting hole 102. The two ends of the mounting hole 102 are respectively connected to the outside and the first flow hole 101.

[0029] It should be noted that the second connecting part 13 is close to the end of the first connecting pipe 100 and is fixedly connected to the first connecting pipe 100 by bolt connection, so as to define the position of the second connecting pipe 10. At the same time, the first flow hole 101 is also connected to the first connecting pipe 100.

[0030] It is worth mentioning that the quick-connect fitting assembly for draining the remaining liquid in the tank truck also includes a flow guiding component 20. One end of the flow guiding component 20 is rotatably disposed in the first flow hole 101, and the other end is located outside. That is, by rotating the flow guiding component 20, the first flow hole 101 can be opened or closed.

[0031] Specifically, the flow guiding assembly 20 includes a plug 21, a shaft 22, and a handle 23. The plug 21 passes through the mounting hole 102 and is placed inside the first flow hole 101. One end of the shaft 22 is fixedly connected to the top of the plug 21, and the other end passes through the mounting hole 102 and is placed externally. The handle 23 is horizontally positioned, and one end of the handle 23 is fixedly connected to the top of the shaft 22. Specifically, the user can hold the end of the handle 23 away from the shaft 22 and rotate the handle 23 to drive the plug 21 to rotate. Those skilled in the art should understand that the connection between the shaft 22 and the plug 21 can be integrally formed or welded, and the handle 23 and the shaft 22 can be fixed by external bolts to limit the position of the handle 23.

[0032] Other examples Figure 1As shown, the diameter of the mounting hole 102 is larger than the shaft diameter of the shaft 22, thus reserving space for the subsequent installation of other components. Specifically, multiple sealing plugs 24 can be installed in the mounting hole 102, all of which are sleeved on the shaft 22. The sealing plug 24 located at the bottom contacts the plug 21, and the sealing plug 24 located at the top is flush with the top of the protrusion 14. The flow guiding assembly 20 also includes a cover plate 25, which is threaded to the outer wall of the protrusion 14 to seal the top of the mounting hole 102 and limit the position of the multiple sealing plugs 24. At the same time, the shaft 22 also passes through the cover plate 25. That is, the sealing performance at the mounting hole 102 is ensured by the multiple sealing plugs 24.

[0033] It is worth mentioning that the end of the first connecting part 11 opposite to the second connecting part 13 also has an assembly hole 103. The assembly hole 103 is connected to the first flow hole 101, and the diameter of the assembly hole 103 is larger than the diameter of the first flow hole 101. A limiting plate 30 is also installed at the assembly hole 103. The limiting plate 30 is rotatably disposed in the assembly hole 103, and the thickness of the limiting plate 30 is smaller than the depth of the assembly hole 103. The connection between the limiting plate 30 and the assembly hole 103 can be implemented as a threaded connection.

[0034] Furthermore, the center of the limiting plate 30 also has an insertion hole 301, and the wall surface forming the insertion hole 301 also has a plurality of evenly distributed notches 302. The plurality of notches 302 and the insertion hole 301 are all connected to the assembly hole 103, and the size of the insertion hole 301 is larger than the size of the first flow hole 101.

[0035] Specifically, the quick-connect fitting assembly for draining remaining liquid from the tanker truck further includes a connector 40. The connector 40 is configured to pass through the insertion hole 301 of the limiting plate 30 and rotate at a predetermined angle to be confined between the limiting plate 30 and the bottom wall forming the assembly hole 103. That is, one side of the connector 40 contacts the bottom wall forming the assembly hole 103, and the other side contacts the limiting plate 30. In addition, the side of the connector 40 facing the first flow hole 101 also has a second flow hole 401. The second flow hole 401 communicates with the first flow hole 101, and the size of the second flow hole 401 is smaller than the size of the first flow hole 101. That is, the liquid in the tank can pass sequentially through the first connecting pipe 100, the second connecting pipe 100, and the connector 40. It should be understood by those skilled in the art that the end of the connector 40 facing away from the second connecting pipe 100 is configured to connect to an external pipe, thereby guiding the liquid flowing into the connector 40 to an external storage tank.

[0036] Specifically, the outer wall of the connector 40 also has a plurality of evenly distributed protrusions 41, each of which corresponds one-to-one with a plurality of notches 302. The size of the protrusions 41 is the same as that of the notches 302. When the connector 40 passes through the insertion hole 301, the plurality of protrusions 41 pass through the corresponding notches 302 respectively. At this time, the user can rotate the connector 40 to make the plurality of protrusions 41 and the plurality of notches 302 misaligned, thereby limiting the position of the connector 40. In addition, to ensure the sealing here, the connector 40 also has an annular mounting groove 402 on the side facing the second connecting pipe 10. A sealing ring 50 is installed in the annular mounting groove 402, and the size of the annular mounting groove 402 is larger than the size of the first flow hole 101. Additionally, a grip bar (not shown in the figure) can be welded to the side of the connector 40 opposite to the second connecting pipe 10. Since the connector 40 and the mounting hole 103 are connected by a thread, the user can rotate the connector 40 through the grip bar to control the distance between the connector 40 and the bottom wall forming the mounting hole 103, ensuring that the connector 40 can be locked in place. Then, the limiting plate 30 can be rotated to squeeze the connector 40, thereby squeezing the sealing ring 50 located in the annular mounting groove 402 to ensure the sealing at the junction of the first flow hole 101 and the second flow hole 401.

[0037] In summary, the quick-connect fitting assembly for draining residual liquid from tank trucks, based on the embodiments of this application, is explained, providing advantages such as ease of use, detachability, and simple structure.

[0038] It is worth mentioning that, in this embodiment, the quick-connect fitting assembly for draining residual liquid from tank trucks has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the quick-connect fitting assembly for draining residual liquid from tank trucks provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
