[0003] In order to solve the above technical problems, the present invention provides a type IV gas cylinder clamp and fixing device.

[0009] Furthermore, in the above-mentioned Type IV gas cylinder clamp and fixing device, the radial expansion mechanism is composed of a radial expansion guide I, a radial expansion compensator, a radial expansion guide II, and a binding locking nut from top to bottom.

[0010] Furthermore, in the above-mentioned Type IV gas cylinder clamp and fixing device, the radial expansion compensator is a spring.

[0011] Furthermore, in the above-mentioned Type IV gas cylinder clamp and fixing device, a guide groove is provided on the surface of the gas cylinder support guide mechanism, and the direction of the guide groove is consistent with the axial direction of the gas cylinder.

DETAILED DESCRIPTION

[0030] Example 1 A type IV gas cylinder clamp and fixing device

[0031] like Figure 1-2 As shown, a type IV gas cylinder clamp and fixing device includes a gas cylinder strap 1, two sets of radial expansion mechanisms 6, a support 8 and a plurality of diameter compensation mechanisms 2 with different thicknesses; the radial expansion mechanism 6 is composed of a radial expansion guide I 6-1, a radial expansion compensator 6-2, a radial expansion guide II 6-3, and a strap locking nut 6-4 from top to bottom; the radial expansion compensator 6-2 is a spring.

[0032] N-shaped protrusions are provided at both ends of the support 8, and a slide groove 7 is provided on the plane of the n-shaped protrusion. The slide groove 7 is a rectangular opening with semicircular ends, and its length direction is consistent with the axial direction of the gas cylinder. The two ends of the gas cylinder strap 1 are respectively passed through the corresponding slide groove 7, radial expansion guide I 6-1, radial expansion compensator 6-2, radial expansion guide II 6-3 and strap locking nut 6-4 through welded studs 9 and are screwed and installed on the support 8. The stud 9 that can slide in the slide groove 7 drives the gas cylinder strap 1 to move, so that the gas cylinder strap 1 can move with the expansion of the gas cylinder in the axial direction. The radial expansion mechanism 6 solves the problem of the gas cylinder strap not fitting and the failure of holding caused by the real-time change of the diameter during the inflation and deflation of the gas cylinder.

[0033] A gas cylinder support support plate 5 is integrally connected in the horizontal vertical direction of the support 8 , and screw holes are provided on the gas cylinder support support plate 5 for fixing the gas cylinder support support plate 5 to the end surface of the gas cylinder support 10 by screws.

[0034] The support plate 5 of the gas cylinder support is provided with an arc groove corresponding to the position of the gas cylinder strap 1, and the surface of the arc groove is fixedly provided with a gas cylinder support guide mechanism 4, and the surface of the gas cylinder support guide mechanism 4 is provided with a guide groove, and the direction of the guide groove is consistent with the axial direction of the gas cylinder, and the surface of the gas cylinder support guide mechanism 4 is provided with a sliding base 3, and a screw hole is provided on the sliding base 3. The device of the present invention adopts a sliding base 3, and when the gas cylinder expands along the axial direction during the inflation process, the friction between the gas cylinder and the sliding base 3 pushes the sliding base 3 to slide along the axial expansion direction of the gas cylinder, and the bottom of the sliding base 3 is provided with a gas cylinder support guide mechanism 4, which can ensure that the sliding base 3 moves along the guide groove on the gas cylinder support guide mechanism 4, avoiding the problem of sliding dislocation and sliding direction deviation, so that the problem of excessive local force deformation and failure of the strap caused by repeated axial expansion and contraction of the gas cylinder can be solved.

[0035] The device of the present invention also uses diameter compensation mechanisms 2 of different numbers and thicknesses to meet the needs of different nominal diameters of gas cylinders. When the nominal diameter of the gas cylinder changes, it is only necessary to adjust the thickness and number of the diameter compensation mechanism 2 to adapt to different gas cylinder diameters. The modular design makes the component have the conditions for mass production, which is conducive to cost control. At the same time, the diameter compensation mechanism 2 is provided with a screw hole, the position of the screw hole corresponds to the position of the screw hole on the sliding base 3, and the two are connected together by tightening bolts passing through the corresponding screw holes on the diameter compensation mechanism 2 and the sliding base 3. When the gas cylinder has axial expansion, the friction between the gas cylinder and the diameter compensation mechanism 2 pushes the diameter compensation mechanism 2 and the sliding base 3 to slide along the direction of the axial expansion of the gas cylinder. The bottom of the sliding base 3 is provided with a gas cylinder support guide mechanism 4, which can ensure that the sliding base 3 moves along the guide groove on the gas cylinder support guide mechanism 4 to avoid the problem of sliding dislocation and sliding direction deviation.

[0036] Example 2 Multi-connection Type IV gas cylinder clamp and fixing device

[0037] like Figure 3 As shown, the multi-connected type IV gas cylinder clamp and fixing device is different from the type IV gas cylinder clamp and fixing device of Example 1 in that two or more type IV gas cylinder clamps and fixing devices are connected together by an integrated support 11 formed by connecting two or more supports, and n-shaped protrusions are respectively provided at both ends of the integrated support 11 and at the connecting position of adjacent supports, and a slide groove 7 is respectively opened on the plane of the n-shaped protrusion at the two end positions, and two slide grooves 7 are opened in parallel on the plane of the n-shaped protrusion at the connecting position of adjacent supports.

[0038] Example 3: Method for using a type IV gas cylinder clamp and fixing device

[0039] like Figure 4 As shown, a method for using a type IV gas cylinder clamp and fixing device includes the following steps:

[0040] 1) Two type IV gas cylinder clamps and fixing devices without gas cylinder straps 1 and radial expansion mechanisms 6 are fixed to the two end surfaces of the gas cylinder support 10 by screws through the screw holes on the gas cylinder support support plate 5.

[0041] 2) Place the gas cylinder on the surface of the gas cylinder support 10 and the two IV-type gas cylinder clamps and the sliding base 3 of the fixing device.

[0042] 3) Pass the stud 9 at the end of the gas cylinder strap 1 through its corresponding slide groove 7, radial expansion guide I 6-1, radial expansion compensator 6-2, radial expansion guide II 6-3 and strap locking nut 6-4 and tighten them to install on the support 8.

[0043] The device of the present invention also uses diameter compensation mechanisms 2 of different numbers and thicknesses to be placed on the surface of the sliding base 3, which can meet the needs of different nominal diameters of gas cylinders (the original diameter of the gas cylinder when not inflated). When the nominal diameter of the gas cylinder changes, only the thickness and number of the diameter compensation mechanism 2 need to be adjusted to adapt to different gas cylinder diameters. The diameter compensation mechanism 2 and the sliding base 3 are connected together by tightening bolts passing through corresponding screw holes on the diameter compensation mechanism 2 and the sliding base 3. When the gas cylinder expands axially, the friction between the gas cylinder and the diameter compensation mechanism 2 pushes the diameter compensation mechanism 2 and the sliding base 3 to slide along the direction of the axial expansion of the gas cylinder, and the sliding direction is constrained by the gas cylinder support guide mechanism 4.

[0044] By using a multi-link IV-type gas cylinder clamp and fixing device, when the diameters of the gas cylinders are different, different thicknesses and numbers of diameter compensation mechanisms 2 can be placed on the surface of the sliding base 3 as needed to adapt to different gas cylinder diameters.
