Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0050] See also Figures 1 to 10In an embodiment of the present invention, a self-locking tank refueling truck reel for eliminating vibration and looseness is installed on a tank truck and includes: a box body 1, a connector 5 and a self-sealing component.

[0051] A winding roller 4 is rotatably installed in the box body 1, and a protective grille 2 is provided on the side of the box body 1, and an oil delivery pipe 7 is wound on the winding roller 4;

[0052] The connector 5 is fixedly connected to the box body 1 and is connected to the oil delivery pipe 7 through a connecting structure, wherein the connecting structure comprises a connecting portion 501 arranged at the lower end of the connector 5, and a plurality of through grooves 502 are equidistantly arranged on the connecting portion 501;

[0053] The communication structure also includes a connecting ring 6 connected to the oil pipeline 7. The connecting ring 6 is sealed and rotatably connected to the connecting portion 501. When the fuel enters the connector 5, it can enter the oil pipeline 7 through the through groove 502 and the connecting ring 6.

[0054] Specifically, an annular cavity is formed between the connecting ring 6 and the outer wall of the connecting portion 501. After the fuel enters the annular cavity, it can enter the oil pipe 7 through the through groove 502. Based on this, the connecting ring 6 can be in any position relative to the connecting seat 501. Fuel can be transported, thereby ensuring that fuel can be added when the oil pipe 7 is pulled to different lengths.

[0055] See also Figure 6 to Figure 8 , the self-sealing component is arranged on the connector 5, and the self-sealing component includes an opening and closing structure and an elastic sealing structure, and a locking portion 18 is arranged at one end of the elastic sealing structure away from the opening and closing structure, and the locking portion 18 is adapted to a locking ring 19 installed on the winding roller 4, and a plurality of groups of locking grooves 1901 are arranged equidistantly on the locking ring 19 at a circumference, and each group of the locking grooves 1901 is symmetrically arranged with two groups of inclined surfaces 1902 at one end facing the connector 5, and the inclined surfaces 1902 can guide the locking portion 18 to enter the locking groove 1901;

[0056] When the fuel enters the connector 5, the opening and closing structure and the elastic sealing structure can be driven to operate, so that the locking portion 18 is inserted into the locking ring 19;

[0057] The opening and closing structure comprises a fixing member 12 fixedly installed in the connector 5 and a sliding member 13 sealingly and slidably installed in the connector 5, wherein the fixing member 12 is provided with a plurality of groups of dredging holes 1201, and the sliding member 13 is provided with a plurality of groups of communicating holes 1301 offset from the dredging holes 1201;

[0058] The opening and closing structure further includes a fitting structure connecting the sliding member 13 and an elastic sealing structure, wherein the fitting structure can make the locking portion 18 move toward the locking ring 19 when the sliding member 13 moves away from the fixing member 12, and the fitting structure includes a connecting plate 14 fixedly connected to the sliding member 13, and an inclined groove 1401 is provided on the connecting plate 14;

[0059] The interlocking structure further includes an interlocking shaft 1501 connected to the elastic sealing structure, and the interlocking shaft 1501 can slide in the inclined groove 1401 .

[0060] In the initial state, with the support of the elastic sealing structure, the engaging shaft 1501 is at the lower end of the inclined groove 1401, and the sliding part 13 is in a sealed fit with the fixing part 12. At this time, the connector 5 can be sealed, which can reduce the risk of fuel leakage to a certain extent without adding fuel, and can shorten the time for fuel drainage after adding fuel.

[0061] After the oil pipeline is connected to the oil filling port of the oil-using equipment, when the fuel in the refueling truck is transported to the connecting head 5, the pressure of the connecting head 5 on the upper part of the fixing part 12 will increase, and under the action of the pressure, the sliding part 13 can move away from the fixing part 12, so that there can be a gap between the fixing part 12 and the sliding part 13. At this time, the fuel can enter the gap through the dredging hole 1201, and enter the lower end of the connecting head 5 through the connecting hole 1301, and finally enter the oil-using equipment. When the sliding part 13 moves away from the fixing part 12, the connecting plate 14 and the inclined groove 1401 will also move away from the fixing part 12. At this time, under the cooperation of the inclined groove 1401 and the interlocking shaft 1501, the interlocking shaft 1501 can move toward the elastic sealing structure, thereby driving the locking part 18 to be inserted into the locking groove 1901, so that in the process of filling the oil-using equipment with fuel, the oil pipeline 7 can have higher stability. Due to the vibration of the vehicle, the refueling hose continues to slide out, affecting the operation of the operating platform.

[0062] See also Figure 6-7 The elastic sealing structure includes a connecting sleeve 11 connected to the connecting head 5, a piston 17 is sealingly and slidably installed in the connecting sleeve 11, and a telescopic shaft 15 passing through the connecting sleeve 11 is connected to the piston 17, one end of the telescopic shaft 15 is connected to the fitting shaft 1501, and the other end is connected to the locking portion 18;

[0063] The telescopic shaft 15 is also sleeved with a cylindrical spring 16 , one end of the cylindrical spring 16 is connected to the piston 17 , and the other end of the cylindrical spring 16 is connected to the inner wall of the connecting sleeve 11 .

[0064] In the initial state, the cylindrical spring 16 is in a compressed state, so that the engaging shaft 1501 can be at the lower end of the inclined groove 1401, thereby ensuring the sealed grounding state of the sliding member 13 and the fixing member 12. When the pressure in the connecting head 5 increases, the sliding member 13 will move away from the fixing member 12, and the connecting plate 14 can move away from the fixing member 12. At this time, the engaging shaft 1501 can drive the telescopic shaft 15 to move toward the cylindrical spring 16, further compressing the cylindrical spring 16 while allowing the locking portion 18 to be inserted into the locking groove 1901, thereby ensuring the stability of the oil pipeline 7 in the oil delivery state.

[0065] To sum up, under the action of the columnar spring 16, the sliding part 13 can maintain a sealed fit with the fixing part 12, so that on the one hand it can play a certain role in preventing fuel leakage, and on the other hand it can shorten the time waiting for the fuel to drain after fuel filling. In the process of filling oil into the oil-using equipment, the sliding part 13 can move away from the fixing part 12, and with the cooperation of the inclined groove 1401 and the interlocking shaft 1501, the locking part 18 can be inserted into the locking groove 1901 to lock the winding roller 4, so that in the process of filling fuel into the oil-using equipment, the oil pipe 7 can have higher stability. Due to the vibration of the vehicle, the refueling hose continues to slide out, affecting the operation of the operating platform.

[0066] See also Figure 3-4 , Figure 9-10 , eliminating the vibration and looseness of the self-locking tank refueling truck reel, and also includes: a slider 29, a follower structure and a telescopic connection structure.

[0067] The slider 29 is slidably arranged on the box body 1, and dust shielding mesh plates 3 are arranged on both sides of the slider 29 to prevent external dust from entering the box body 1, and a flushing member is rotatably installed on the slider 29, and the oil delivery pipe 7 can pass through the flushing member, and the flushing member includes a follower sleeve 25 rotatably arranged through the slider 29, and a brush head 26 is arranged on one side of the follower sleeve 25, and brushes 27 and overflow holes 2601 are equidistantly arranged on the brush head 26 at a circumferential distance;

[0068] The scrubbing head 26 is also provided with inclined arc surfaces 2602 at equal intervals in a circumference, and the lower part of the scrubbing head 26 can extend into the water tank 28 installed on the box body 1;

[0069] The telescopic connection structure connects the winding roller 4 and the flushing member, and the telescopic connection structure can make the flushing member rotate synchronously with the winding roller 4. The winding roller 4 is coaxially fixedly connected with a first bevel gear 8, and the first bevel gear 8 is meshed with a second bevel gear 9 rotatably mounted on the box body 1. One end of the second bevel gear 9 is connected to a hand wheel 10. When the oil pipeline 7 is wound up, the second bevel gear 9 can be driven to rotate by rotating the hand wheel 10, and the winding roller 4 can be driven to rotate through the first bevel gear 8;

[0070] The telescopic connection structure includes a second hinged rod 33 rotatably connected to the rotating shaft of the handwheel 10 and a first hinged rod 31 rotatably connected to the follower sleeve 25. The first hinged rod 31 is rotatably connected to the second hinged rod 33, and two pulleys are rotatably installed at the connection between the two. One of the pulleys is connected to the follower sleeve 25 through a first belt 30, and the other pulley is connected to the rotating shaft of the handwheel 10 through a second belt 32, so that when the follower sleeve 25 is raised or lowered, the follower sleeve 25 can always rotate with the handwheel 10.

[0071] When the oil pipeline 7 is pulled or reversely wound, the follower sleeve 25 can rotate along with the hand wheel 10 during the rotation of the hand wheel 10. At this time, the scrubbing head 26 can make a circular motion, wherein the water tank 28 is filled with cleaning liquid (containing alcohol for easy volatilization), and the lower part of the scrubbing head 26 is immersed in the cleaning liquid, so that the brush 27 at the lower part of the scrubbing head 26 can absorb the cleaning liquid, and when it rotates to the upper part of the scrubbing head 26, the cleaning liquid can enter the scrubbing head 26 and act on the oil pipeline 7 to clean the outer surface of the oil pipeline 7.

[0072] Furthermore, the cleaning liquid adsorbed on the brush 27 can also enter the interior of the scrubbing head 26 through the overflow hole 2601, thereby increasing the amount of cleaning liquid entering the interior of the scrubbing head 26 and ensuring the cleaning effect.

[0073] Furthermore, since the scrubbing head 26 is provided with an inclined arc surface 2602 inside, the cleaning liquid can flow back into the water tank 28 under the guidance of the inclined arc surface 2602 after cleaning, preventing the cleaning liquid from remaining in the scrubbing head 26 and causing secondary contamination.

[0074] Through the above arrangement, when the oil pipeline 7 is pulled or reversely reeled, the scrubbing head 26 can drive the brush 27 to make a circular motion, and absorb the cleaning liquid when immersed in the cleaning liquid in the water tank 28, and then when the brush 27 moves to the upper part of the scrubbing head 26, the cleaning liquid is drained to the oil pipeline 7, and under the action of the brush 27, the oil pipeline 7 is fully scrubbed to improve the cleanliness of the outside of the oil pipeline 7.

[0075] See also Figure 3-4 , Fig. 9The follower structure connects the winding roller 4 and the flushing part. When the winding roller 4 rotates, the follower structure can drive the flushing part to perform a lifting action. The follower structure includes teeth 20 equidistantly arranged on the winding roller 4 and a gear 21 rotatably installed in the box body 1. The gear 21 is meshed with the teeth 20, and the gear 21 is connected to a screw rod 23 rotatably installed in the box body 1. The screw rod 23 is provided with a threaded sleeve 22 threadedly connected thereto. The threaded sleeve 22 is connected to the follower sleeve 25 through a connecting plate 24.

[0076] When in use, when the winding roller 4 rotates, the teeth 20 connected thereto will make a circular motion, and at the same time, the gear 21 can rotate by meshing with the teeth 20, thereby driving the screw rod 23 to rotate, and making the threaded sleeve 22 threadedly connected to the screw rod 23 move along the length direction of the screw rod 23, thereby driving the follower sleeve 25 to move along the axial direction of the winding roller 4. At this time, in conjunction with the rotation of the winding roller 4, the oil pipeline 7 can be evenly wound on the winding roller 4, and the oil pipeline 7 is prevented from being piled on the winding roller 4, so as to improve the flatness of the oil pipeline 7 on the winding roller 4 and reduce the resistance of pulling or reverse winding of the oil pipeline 7.

[0077] Through the above arrangement, during the rotation of the winding roller 4, the follower sleeve 25 can perform an ascending or descending action, so that the oil pipeline 7 can be evenly wound on the winding roller 4 when winding, so as to improve the flatness of the oil pipeline 7 on the winding roller 4 and reduce the resistance of pulling or reverse winding of the oil pipeline 7.

[0078] The reel self-locking method adopts the self-locking tank tank reel for eliminating vibration and looseness, and comprises:

[0079] Step 1: Pull the oil pipeline 7 to connect one end of the oil pipeline 7 to the oil-using equipment;

[0080] Step 2: Start the fuel truck and deliver fuel into the connector 5;

[0081] Step 3: When the fuel passes through the connector 5, the pressure can drive the opening and closing structure to move, and the locking portion 18 is driven to be inserted into the locking ring 19 through the elastic sealing structure, so that the winding roller 4 is axially locked.
