[0033] like Figure 4 As shown, the quick connector 100 of this utility model is installed on the loading arm and is used to connect with the filling pipe 200 of the tanker truck. The filling pipe 200 of the tanker truck has an annular groove 201.

[0034] like Figure 1As shown, the quick connector 100 includes: a connector body 10, a sliding sleeve 20, a docking mechanism 30, and a locking mechanism 40. The connector body 10 is used to dock with the filling pipe 200. The sliding sleeve 20 slides along the connector body 10 to drive the docking mechanism 30 to engage with the annular groove 201 of the filling pipe 200. The locking mechanism 40 is used to fix the position of the sliding sleeve 20 to prevent the sliding sleeve 20 from slipping. By using the method of docking the connector body 10 with the filling pipe 200, driving the docking mechanism 30 to engage with the annular groove 201 of the filling pipe 200, and fixing the position of the sliding sleeve 40, it is beneficial to quickly and stably dock the quick connector 100 with the filling pipe 200 of the tanker truck, thereby greatly reducing the docking time and improving the filling efficiency of the loading arm.

[0035] The following text, combined with Figures 1 to 4 Further explanation is provided regarding the aforementioned quick connector 100.

[0036] like Figures 1 to 2 As shown, the connector body 10 includes an oil supply pipe 11 and a guide pipe 12. The oil supply pipe 11 has an oil outlet 111. The guide pipe 12 is arranged around the oil supply pipe 11 and forms a docking space 121 with the oil supply pipe 11 for the insertion of the filling pipe 200. Furthermore, the connector body 10 also includes a transition flange 13. The transition flange 13 is integrally formed with the oil supply pipe 11 and the guide pipe 12 and is installed on the loading arm to improve the assembly of the connector body 10 and the loading arm. In addition to improving efficiency, the connector body 10 also includes a buffer pad 14, which is connected to the guide pipe 12. Specifically, the buffer pad 14 includes a buffer part 141 and a stop part 142. The buffer part 141 abuts against the outer wall of the filling pipe 200, and the stop part 142 fits against the outer wall of the guide pipe 12. The buffer pad 14 can effectively reduce the instantaneous impact force when the guide pipe 12 contacts the tanker truck, thereby effectively reducing the damage to the guide pipe 12 or the tanker truck due to collision.

[0037] like Figure 2As shown, the sliding sleeve 20 slides along the guide tube 12. There are two sets of docking mechanisms 30, which are arranged on opposite sides of the oil pipeline 11. Each docking mechanism 30 includes a locking head 31, a locking rod 32, and a connecting rod 33. The locking head 31 is connected to the locking rod 32 and is used to engage with the annular groove 201 of the filling pipe 200. The locking rod 32 is rotatably mounted on the guide tube 12. The connecting rod 33 is rotatably connected to the end of the locking rod 32 away from the locking head 31 and is rotatably mounted on the sliding sleeve 20. The guide tube 12 is provided with a movable groove 122, and the locking rod 32 is movably disposed in the movable groove 122. The sliding sleeve 20 is provided with a relief groove 21, and the end of the connecting rod 33 located in the relief groove 21 is rotatably connected to the sliding sleeve 20.

[0038] like Figure 3 As shown, the locking mechanism 40 is connected to the sliding sleeve 20 and is used to engage with the guide tube 12. Specifically, the locking mechanism 40 includes a fixed handle 41, a locking handle 42, and an elastic element 43. The fixed handle 41 is fixedly installed on the sliding sleeve 20. The locking handle 42 is slidably connected to the fixed handle 41 and passes through the sliding sleeve 20 to be inserted into the guide tube 12. The elastic element 43 is used to provide elastic force for the locking handle 42 to be inserted into the guide tube 12. The locking handle 42 includes a body 421 and a plug rod 422. The body 421 is slidably connected to the fixed handle 41. The plug rod 422 passes through the sliding sleeve 20 to be inserted into the guide tube 12. The guide tube 12 is provided with two insertion holes 123, and either insertion hole 123 is inserted into the plug rod 422.

[0039] like Figure 2 and Figure 4 As shown, the sliding sleeve 20 has a first usage position and a second usage position, as follows: Figure 2 As shown, when the sliding sleeve 20 is in the first use position, the lock head 31 is separated from the docking space 121, as... Figure 4 As shown, when the sliding sleeve 20 is in the second use position, the locking head 31 protrudes into the docking space 121 and engages with the annular groove 201 of the filling tube 200.

[0040] like Figure 4As shown, when using the quick connector 100 provided in this application: the oil supply pipe 11 of the control connector body 10 is inserted into the filling pipe 200. At this time, the filling pipe 200 is inserted into the docking space 121 of the connector body 10. Hold the fixing handle 41 of the locking mechanism 40, pull the insertion rod 422 of the locking handle 42 to separate it from one of the insertion holes 123 of the guide tube 12, control the sliding sleeve 20 to slide along the guide tube 12 to the second use position, and drive the connecting rod 33 through the sliding sleeve 20 to drive the locking rod 32 to rotate, so that the locking head 31 of the docking mechanism 30 is engaged in the annular groove 201 of the filling pipe 200. Release the locking handle 42, so that the insertion rod 422 of the locking handle 42 is inserted into the other insertion hole 123, thereby realizing the docking of the quick connector 100 and the filling pipe 200.

[0041] The beneficial effects of the quick connector 100 provided in this application are as follows: the oil delivery pipe 11 of the connector body 10 is connected to the filling pipe 200 of the tanker truck. During the process of the sliding sleeve 20 sliding along the guide pipe 12 of the connector body 10, the locking rod 32 and the locking head 31 are driven by the connecting rod 33 to connect with the filling pipe 200 of the tanker truck. The locking mechanism 40 is engaged with the guide pipe 12 to prevent the sliding sleeve 20 from sliding. This method allows the locking head 31 to connect with the filling pipe 200 of the tanker truck by changing the position of the sliding sleeve 20 on the guide pipe 12, thereby saving a lot of connection time and achieving the purpose of improving the filling efficiency of the loading arm.
