Detailed Implementation

[0022] like Figure 1 and Figure 2 As shown, this embodiment provides an explosion-proof funnel for tank trucks, including a funnel body 1, a first oil guide pipe 2, a second oil guide pipe 3, and a static discharge device 4. The top of the first oil guide pipe 2 is connected to the funnel body 1, and the second oil guide pipe 3 is sleeved with the first oil guide pipe 2. The second oil guide pipe 3 can rotate and slide relative to the first oil guide pipe 2, and a locking mechanism 5 is provided between the second oil guide pipe 3 and the first oil guide pipe 2. The static discharge device 4 is connected to the funnel body 1, the first oil guide pipe 2, or the second oil guide pipe 3 to release static electricity from the funnel body 1, the first oil guide pipe 2, and the second oil guide pipe 3 in a timely manner. The funnel body 1, the first oil guide pipe 2, and the second oil guide pipe 3 are all made of metal. The first oil guide pipe 2 and the funnel body 1 are an integral structure, and the second oil guide pipe 3 can slide along the first oil guide pipe 2, thereby adjusting the overall length of the oil guide pipe. For small tank trucks, the second oil guide pipe 3 can be slid upward along the first oil guide pipe 2 to reduce the overall length of the oil guide pipe; for large tank trucks, the second oil guide pipe 3 can be slid downward along the first oil guide pipe 2 to increase the overall length of the oil guide pipe.

[0023] In this invention, the second oil guide pipe 3 can rotate and slide relative to the first oil guide pipe 2. The position of the oil outlet of the second oil guide pipe 3 can be adjusted according to different tank depths, so that the second oil guide pipe 3 can extend into the tank to different depths, thereby meeting the oil filling needs of different types of tank trucks.

[0024] like Figure 2 As shown, in this embodiment, the inner diameter of the second oil guide tube 3 is larger than the outer diameter of the first oil guide tube 2, and the bottom ends of both the first oil guide tube 2 and the second oil guide tube 3 are provided with a 45° bevel angle. The second oil guide tube 3 is sleeved on the outside of the first oil guide tube 2, so that the second oil guide tube 3 can rotate and slide relative to the first oil guide tube 2.

[0025] The second oil guide tube 3 is provided with an anti-detachment mechanism between it and the first oil guide tube 2. The anti-detachment mechanism is used to prevent the second oil guide tube 3 from detaching from the first oil guide tube 2. By setting the anti-detachment mechanism, this utility model ensures that the second oil guide tube 3 will not detach from the first oil guide tube 2 when sliding relative to it, making it more convenient to use.

[0026] like Figure 2 As shown, specifically, the anti-detachment mechanism includes a first anti-detachment ring 6 and a second anti-detachment ring 7. The first anti-detachment ring 6 is located on the bottom outer side of the first oil guide tube 2, and the second anti-detachment ring 7 is located on the top inner side of the second oil guide tube 3. The second anti-detachment ring 7 and the first anti-detachment ring 6 can abut against each other to prevent the second oil guide tube 3 from detaching from the first oil guide tube 2. When the second oil guide tube 3 slides downward to its lowest point, the second anti-detachment ring 7 at the top of the second anti-detachment ring 7 abuts against the first anti-detachment ring 6 at the bottom of the first oil guide tube 2, thereby preventing the second oil guide tube 3 from detaching from the first oil guide tube 2. In addition, the first anti-detachment ring 6 contacts the inner wall of the second oil guide tube 3, and the second anti-detachment ring 7 contacts the outer wall of the first oil guide tube 2. The first anti-detachment ring 6 and the second anti-detachment ring 7 can guide the second oil guide tube 3 to rotate.

[0027] In one specific embodiment, the locking mechanism 5 includes a locking member. The second oil guide tube 3 has several locking holes. The locking member is disposed within the locking holes and abuts against the outer wall of the first oil guide tube 2 to fix the second oil guide tube 3 onto the first oil guide tube 2. Specifically, the locking member includes a locking bolt 8, and the locking holes are threaded holes 9 adapted to the locking bolt 8.

[0028] In this embodiment, four locking bolts 8 and four threaded holes 9 are provided in a one-to-one correspondence. The four threaded holes 9 are arranged in a ring evenly on the second oil guide tube 3. After the four locking bolts 8 pass through the four threaded holes 9, they abut against the outer wall of the first oil guide tube 2, thereby fixing the second oil guide tube 3 on the first oil guide tube 2.

[0029] like Figure 2As shown, in this embodiment, the surface of the first oil guide tube 2 is provided with a plurality of first oil outlet holes 10, and the surface of the second oil guide tube 3 is provided with a plurality of second oil outlet holes 11. Preferably, the size of the second oil outlet hole 11 is the same as the size of the first oil outlet hole 10. During the filling process, the oil inflow rate can be adjusted using the first oil outlet holes 10 and the second oil outlet holes 11. The specific operation is as follows: control the second oil guide tube 3 to rotate relative to the first oil guide tube 2, so that the second oil outlet hole 11 of the second oil guide tube 3 is aligned with the first oil outlet hole 10 of the first oil guide tube 2, and the oil in the first oil guide tube 2 flows out through the first oil outlet hole 10 and the second oil outlet hole 11, increasing the oil inflow rate; control the second oil guide tube 3 to rotate relative to the first oil guide tube 2, so that the second oil guide tube 3 blocks the first oil outlet hole 10 of the first oil guide tube 2 to prevent oil splashing, and the oil in the first oil guide tube 2 flows out through the oil outlet at its end, reducing the oil inflow rate.

[0030] In one specific embodiment, the static discharge device 4 includes a static discharge wire 12 and a static grounding clamp 13. One end of the static discharge wire 12 is connected to the funnel body 1, and the other end is connected to the static grounding clamp 13. Preferably, the static discharge wire 12 is a copper wire. If static electricity is generated during oil refueling, the static electricity is conducted through the static discharge wire 12 to the static grounding clamp 13 and then released to the ground through the static grounding clamp 13, preventing danger during the refueling process.

[0031] This invention's explosion-proof funnel combines the functions of a single-type funnel and an assembled funnel, meeting the needs of different tank trucks and allowing the oil guide pipe to extend and retract freely to meet different tank truck refueling requirements.

[0032] The explosion-proof funnel has a first oil guide pipe 2 and a second oil guide pipe 3. A first anti-detachment ring 6 is installed on the outer bottom of the first oil guide pipe 2, and a second anti-detachment ring 7 is installed on the inner top of the second oil guide pipe 3, allowing the second oil guide pipe 3 to detach from the first oil guide pipe 2. The upper part of the second oil guide pipe 3 has four threaded holes 9 arranged in a ring, each threaded hole 9 fitted with a locking bolt 8. The length of the oil guide pipe can be adjusted according to different tank depths and fixed by the locking bolts 8 before filling operations begin. The total length of the oil guide pipe can reach over 2 meters. After use, the locking bolts 8 are loosened to restore the oil guide pipe to its shortest length for easy storage. The surface of the first oil guide pipe 2 has multiple first oil outlet holes 10, and the surface of the second oil guide pipe 3 has multiple second oil outlet holes 11. Depending on the liquid inflow, the second oil guide pipe 3 can be rotated to block the first oil outlet holes 10, effectively preventing splashing and meeting filling requirements. The funnel body 1 is connected to the static grounding clamp 13 via the static wire 12 to release static electricity to the ground and improve the safety of filling.
