Therefore, it may be changed according to different positions and different use states. Therefore, these and other directional terms should not be construed as limiting terms.

The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

Please refer to fig. 1 and fig. 2, this embodiment discloses a hydrogen fuel vehicle hydrogen bottle fixing strap tightening device, which comprises a bracket base 1, a connecting post 2, a fixing strap 3, an adjusting part 4 and a tightening part 5, the top of the bracket base 1 is provided with an arc-shaped mounting plate 11 matched with the hydrogen bottle 2, the bottom of one side of the bracket base is provided with a connecting part 12, the connecting post 2 is arranged at the other side of the bracket base 1, the connecting post 2 is sequentially provided with a plurality of connecting holes 21 from top to bottom, one end of the fixing strap 3 is connected with the connecting holes 21, the other end of the fixing strap 3 is transversely provided with a first perforation 31, the adjusting part 4 can vertically penetrate out the connecting part 12 from the first perforation 31 downwards, and can press the fixing strap 3, the tightening part 5 and the adjusting part 4 can be adjustably connected with one end of the connecting part 12, and the tightness of the fixing strap 3 can be adjusted by the depth of the tightening part 5 screwed into the adjusting part 4.

Specifically, in the present embodiment, the connecting portion 12 is a hollow sleeve, the adjusting portion 4 is a bolt, and the tightening portion is a nut. The hydrogen bottle fixing belt tightening device is arranged on hydrogen bottle mounting brackets during use, and each mounting bracket is at least provided with two hydrogen fuel automobile hydrogen bottle fixing belt tightening devices. During specific installation, at first lie the hydrogen bottle on the arc mounting panel 11 of support base 1, according to the model of hydrogen bottle, fix fixed band 3 on the connecting hole 21 that corresponds, then the one end of being connected with connecting hole 21 is taut, through bolt 4 from first perforation 31 in vertical pass fixed band 3 and wear out connecting portion 12, then the nut of screwing, the length of hollow cover is worn out to adjusting bolt, the elasticity of fixed band 3 is adjusted to the degree of depth through nut screw in bolt promptly, the installation is simple, it is convenient to adjust, and fixed effectual.

It is further preferable that a cross bar 41 is further disposed between the adjusting portion 4 and the fixing band 3, the cross bar 41 crosses the first through hole 31, a through hole matching with the adjusting portion 4 is disposed on a side surface of the cross bar 41, and a length of the cross bar 41 is greater than or equal to a width of the fixing band 3. Because regulating part 4 (bolt) and fixed band 3 direct contact time, its major part end is pressed the bottom surface of fixed band 3, at the in-process that the car went, because the effect of vibrations, constantly take place the shearing action between bolt and the fixed band 3, cause fixed band 3 and bolted connection's hole to elongate easily, harm fixed band 3 also can make fixed band 3 not hard up simultaneously, influences the stability of hydrogen bottle. After setting up horizontal pole 41, the side of horizontal pole 41 is the arc, can fix the first perforation 31 internal cross-section of area 3 tangent, has increased the area of contact between bolt and the fixed band 3 indirectly promptly to anti shear capacity is stronger, better protection fixed band 3, thereby has guaranteed the stability of hydrogen bottle. In addition, the horizontal pole 41 is the plane with the one side that the bolt pasted mutually, and the plane can be better with the bolt more laminate for the bolt can be better fixed with fixed band 3.

It is further preferable that one end of the fixing strap 3 near the adjusting portion 4 is provided with a U-shaped opening 32 disposed perpendicularly opposite to the first through hole 31, and the opening direction of the U-shaped opening 32 is outward.
