At the upper end of the support base 1, brackets 2 are symmetrically and fixedly installed. At the upper end of the brackets 2, the same hydrogen supply tank 15 is placed. A valve 3 is provided at the right end of the hydrogen supply tank 15. At one end of the valve 3 away from the hydrogen supply tank 15, a connecting flange 4 is fixedly installed. A fixing frame 5 is rotatably connected to the back surface of the bracket 2. A connecting mechanism 6 is provided on the front surface of the fixing frame 5. A fixing mechanism 7 is provided inside the fixing frame 5. Through the connecting flange 4 on the valve 3, it is convenient to replace or externally connect a conveying pipeline during use. In addition, a sealing ring is also provided on the connecting flange 4. When the connecting flange 4 of the externally connected conveying pipeline is connected to the connecting flange 4 on the valve 3, extrusion is formed to ensure the airtightness of the connection between the two;

[0025] The connecting mechanism 6 includes a ferrule 601 fixedly installed on the front surface of the fixing frame 5. An L-shaped block 602 is fixedly installed on the front surface of the bracket 2. A cavity 604 is opened inside the L-shaped block 602. A first movable plate 603 is slidably connected inside the cavity 604. A clamping block 608 is fixedly installed on one side of the first movable plate 603. The clamping end of the clamping block 608 slidably penetrates the inner wall of the cavity 604 and is clamped with the ferrule 601. A pull rod 605 is fixedly installed on the side of the first movable plate 603 away from the clamping block 608. One end of the pull rod 605 slidably penetrates the inner wall of the cavity 604 and is fixedly installed with a pull handle 606. A spring 607 is sleeved outside the pull rod 605. After placing the hydrogen supply tank 15 on the bracket 2 of the support base 1, by flipping the fixing frame 5 on the bracket 2, the ferrule 601 on the fixing frame 5 touches the clamping block 608 on the L-shaped block 602, and the inclined surface of the clamping end of the clamping block 608 is extruded. At the same time, the first movable plate 603 connected to the clamping block 608 slides inside the cavity 604 and compresses the spring 607 on the pull rod 605. When the clamping end of the clamping block 608 corresponds to the clamping position of the ferrule 601, at this time, the spring 607 resets and pushes the clamping block 608 connected to the first movable plate 603 to be clamped into the ferrule 601 for fixation. When opening, by pulling the pull rod 605 with the pull handle 606, the pull rod 605 drives the clamping block 608 on the first movable plate 603 to separate from the ferrule 601, and the fixing frame 5 is flipped and opened on the bracket 2, so that it is convenient to quickly connect the fixing frame 5 on the bracket 2 and facilitate the quick fixation of the hydrogen supply tank 15 in cooperation with the fixing mechanism 7;

[0026] The fixing mechanism 7 includes a second movable plate 701 which is slidably connected to the concave part at the lower end of the fixing frame 5. A clamping block 704 is fixedly installed at the lower end of the second movable plate 701. A screw rod 702 is rotatably connected to the upper end of the second movable plate 701. One end of the screw rod 702 away from the second movable plate 701 is threadedly penetrated through the wall of the fixing frame 5 and a rotating handle 703 is fixedly installed. On the basis of the connection between the fixing frame 5 and the bracket 2, by operating the rotating handle 703 on the fixing frame 5, the rotating handle 703 rotates to drive the screw rod 702 to threadedly expand and contract on the fixing frame 5. At the same time, the lower end of the screw rod 702 rotates to push the second movable plate 701 to slide, and the clamping block 704 on the second movable plate 701 can cooperate with the bracket 2 to conveniently fix the hydrogen supply tank 15 quickly, thus effectively avoiding the situation that the hydrogen supply tank 15 tilts, falls off or drops during transportation.

[0027] Reference Figure 3 , the fixing frame 5 is in a U shape, and first sliding grooves 9 are symmetrically opened in the concave part of the fixing frame 5. The ends of the second movable plate 701 are slidably connected to the inner sides of the first sliding grooves 9. By sliding the second movable plate 701 at the first sliding grooves 9 of the fixing frame 5, the stability of the up-and-down lifting of the second movable plate 701 can be improved.

[0028] Reference Figure 3 , a nut 10 is fixedly installed on the inner side of the upper end of the fixing frame 5. One end of the screw rod 702 is threadedly penetrated through the nut 10. By using the nut 10 installed on the inner side of the upper end of the fixing frame 5, the screw rod 702 can threadedly expand and contract on the fixing frame 5.

[0029] Reference Figure 3 , a first rubber layer 8 is fixedly installed in the concave part at the lower end of the clamping block 704, and a second rubber layer 12 is fixedly installed in the concave part at the upper end of the bracket 2. By using the first rubber layer 8 at the lower end of the clamping block 704 to cooperate with the second rubber layer 12 at the upper end of the bracket 2, the friction force with the tank wall can be increased during the fixing process of the hydrogen supply tank 15, and its stability can be further improved; during transportation, the first rubber layer 8 and the second rubber layer 12 can also play a certain buffering effect on the hydrogen supply tank 15 to a certain extent, ensuring safety.

[0030] Reference Figure 2 and Figure 3 , the bracket 2 is rotatably connected to the back of the fixing frame 5 through a hinge. A handle 11 is fixedly installed on one side of the fixing frame 5. By using the hinge on the bracket 2 and the fixing frame 5, the fixing frame 5 can be conveniently rotated on the bracket 2, and the handle 11 on the fixing frame 5 can be used to conveniently perform a flipping operation on the fixing frame 5 on the bracket 2.

[0031] Reference Figure 4, a second sliding groove 14 is symmetrically opened on the inner side of the cavity 604, and the end of the first movable plate 603 is slidably connected to the inner side of the second sliding groove 14. By using the second sliding groove 14 on the inner side of the cavity 604, the first movable plate 603 can stably slide in the cavity 604.

[0032] Reference Figure 4 , a socket groove 13 is opened on the front surface of the ferrule 601. The upper end surface of the inserting end of the clamping block 608 is beveled. The inserting end of the clamping block 608 and the socket groove 13 are clamped. By opening the socket groove 13 on the ferrule 601, the inserting end of the clamping block 608 can be conveniently inserted therein, so as to quickly connect between the fixing frame 5 and the bracket 2.

[0033] Principle and advantages of use: During the use process, when fixing the hydrogen supply tank 15 on the bracket, first, after placing the hydrogen supply tank 15 on the bracket 2 of the support base 1, by flipping the fixing frame 5 on the bracket 2, the ferrule 601 on the fixing frame 5 touches the clamping block 608 on the L-shaped block 602, and squeezes the bevel of the inserting end of the clamping block 608. At the same time, the first movable plate 603 connected to the clamping block 608 slides inside the cavity 604 and compresses the spring 607 on the pull rod 605. When the inserting end of the clamping block 608 corresponds to the clamping position of the ferrule 601, at this time, the spring 607 resets and pushes the clamping block 608 connected to the first movable plate 603 to be inserted into the ferrule 601 for fixation. On the basis of the connection between the fixing frame 5 and the bracket 2, operate the rotary handle 703 on the fixing frame 5, so that the rotary handle 703 rotates and drives the screw rod 702 to threadedly extend and retract on the fixing frame 5. At the same time, the lower end of the screw rod 702 rotates to push the second movable plate 701 to slide, and the clamping block 704 on the second movable plate 701 can cooperate with the bracket 2 to conveniently fix the hydrogen supply tank 15 quickly;

[0034] When it is necessary to remove the hydrogen supply tank 15, pull the pull rod 605 through the pull handle 606, so that the pull rod 605 drives the clamping block 608 on the first movable plate 603 to separate from the ferrule 601. Then hold the handle 11, and then flip the fixing frame 5 on the bracket 2 to open. When the two fixing frames 5 are opened, the hydrogen supply tank 15 can be taken out.
