[0002] The fiber-wound composite gas cylinder is a kind of cylinder in which fiber reinforced composite material layers are wound on the outer surface of a metal (or other material) inner liner to improve the strength of the cylinder and reduce the weight of the cylinder, and has the advantages of fatigue resistance and corrosion resistance, and is widely used in the fields of aviation, aerospace, medical treatment and sports.

[0003] The fiber-wound composite gas cylinder is generally wound by a wet winding method, that is, continuous fibers are immersed in resin glue, and then wound on a core mold or an inner liner according to a certain linear rule and then cured. The core mold or the inner liner (also called an inner liner) is fixed on a winding device through a connecting tool for winding. The composite gas cylinder needs to be connected with related housings, valves and other accessories through additional structures such as a fixing frame or a support on the surface, and the accuracy of the positions of the fixing frame or the support will affect the installation and positioning of other accessories.

[0015] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below with examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application. The "front side" of the present application refers to Figure 5 the left side of the view direction, and the corresponding "rear side" refers to Figure 5 the right side of the view direction; the "upper" and "lower" directions are consistent with the up and down directions of the view direction. Figure 5 The "upper" and "lower" directions are consistent with the up and down directions of the view direction.

[0016] The principle of the present application is that: as Figure 1、 Figure 2 and Figure 5 As shown, after the composite material gas cylinder is wound, the support 4 needs to be placed in a fixed position on the surface of the winding layer. By utilizing the uniqueness of the docking position between the positioning tool and the connecting rod 3, the shape of the positioning right-angle plate 2 is designed so that it does not interfere with the gas cylinder 5 and the positioning surface 203 is exactly located at the designed installation position of the outer end face of the support 4, which is used for positioning the support 4.

[0017] Example 1: Figures 3 to 5 As shown, a composite material gas cylinder is used to install a positioning tool for a support, including a base 1 and a positioning right-angle plate 2. The upper part of the base 1 is fixedly connected to the positioning right-angle plate 2. The base 1 is a metal block with a rectangular structure. A positioning groove 101 is processed at the lower part of the base 1. The positioning groove 101 is a semi-circular cone-shaped groove. The two semi-circular end faces of the positioning groove 101 pass through the two opposite side walls of the base 1, wherein the semi-circular diameter of the front side wall of the base 1 is smaller than the semi-circular diameter of the rear side wall of the base 1. The shape of the positioning groove 101 is closed with the front end of the connecting rod 3 of the rear head of the gas cylinder 5. The shape is concave and convex, and the positioning right-angle plate 2 includes a horizontal strip 202 and a vertical strip 201. The angle between the horizontal strip 202 and the vertical strip 201 is a right angle. The vertical strip 201 is vertically connected to the upper surface of the base 1. The end face of the vertical strip 201 is welded to the base 1 and one edge of the vertical strip 201 is aligned with the front side wall of the base 1. The end face of the horizontal strip 202 faces the front side of the gas cylinder 5. The end face of the horizontal strip 202 is the positioning surface 203, and the positioning surface 203 contacts the outer end face of the support 4 for positioning the support 4.

[0018] The positioning groove 101 of the base 1 and the positioning connection position of the connecting rod 3 are unique. When the base 1 is positioned and connected with the connecting rod 3, there is a gap between the lower edge of the horizontal strip 202 of the positioning right-angle plate 2 and the gas cylinder. The gap is 1~5mm, and the line segment position of the positioning surface 203 of the horizontal strip 202 vertically projected to the body of the gas cylinder 5 is exactly the designed installation position of the outer end face of the support 4.

[0019] Example 2: Other structures are the same as Example 1, with the difference being that the vertical slats 201 are of a telescopic height-adjustable structure, one being a structure in which two layers of slats are socketed and fixed by locking nuts, or a structure in which two rods are threadedly connected and the height is adjusted by rotation, and the horizontal slats 202 are of a telescopic length-adjustable structure, and their telescopic method is the same as that of the vertical slats 201, so that when the base 1 is positioned and connected to the connecting rod 3, there is a gap between the lower edge of the horizontal slat 202 of the positioning right-angle plate 2 and the gas cylinder 5, and the line segment position of the positioning surface 203 of the horizontal slat 202 vertically projected to the body of the gas cylinder 5 is exactly the designed installation position of the outer end face of the support 4.

[0020] The above is the specific embodiment of the present application and the technical principle used, any modification, equivalent transformation based on the technical scheme of the present application should be included in the protection scope of the present application.
