[0002] The end cap is a component used to seal the end of a container to isolate the internal and external media, also known as an end cap. The end caps of cylindrical containers are generally rotating shells. According to the shape of the end cap surface, it can be divided into convex, conical, flat and combined shapes. A convex end cap refers to a end cap with a convex outer surface, such as a hemispherical, elliptical, dish-shaped and spherical end cap without folding edges. Some gas cylinders use a combined bottom end cap with the convex surface facing inward, which can ensure strength and meet the needs of safe use.

[0003] For example, a metal pipe end cap with Chinese patent publication number CN218914177U includes a pipe end cap, which is the main body of the metal pipe end cap, wherein the outer edge of the pipe end cap is provided with a welding ring, an inner surface layer, which is provided on the inner surface of the pipe end cap, an outer surface layer, which is provided on the outer surface of the pipe end cap, the inner surface layer and the outer surface layer are provided as one body, an adhesive layer, which is provided on the inner surface of the outer surface layer, an anti-seepage layer, which is provided inside the outer surface layer, and a wear-resistant layer, which is provided on the outer surface of the pipe end cap.

[0021] The supporting device 3 includes an extension plate 11, an alignment groove 12, an outer ring ring 13, an alignment plate 14 and a metal pipe 15. The alignment plate 14 is fixedly installed on the outer ring of the metal pipe 15, and the alignment plate 14 is distributed in a ring shape. The extension plate 11 is fixedly installed on the outer ring of the outer ring ring 13, and the extension plate 11 is distributed in a ring shape. The outer ring ring 13 is slidably sleeved on the outer ring of the metal pipe 15, and the outer ring ring 13 is located above the alignment plate 14. The alignment groove 12 is symmetrically opened at the top of the metal pipe 15. Through the setting of the extension plate 11, the U-shaped extension bracket 8 can be supported to work.

[0022] The U-shaped extension bracket 8 is fixedly connected to the bottom end of the extension plate 11 , and the threaded rod 6 is slidably inserted into the top outer ring of the outer ring collar 13 , so that the metal head 5 and the metal pipe 15 can be fitted together.

[0023] The top of the outer ring 13 is provided with circular holes, and the circular holes are distributed in a ring shape, allowing the threaded rod 6 to pass through the interior of the outer ring 13 .

[0024] The positioning rod 10 is vertically aligned with the alignment sleeve 14 , thereby improving the docking accuracy between the alignment sleeve 14 and the positioning rod 10 .

[0025] The sealing ring 4 fits with the inner wall of the alignment groove 12 , so that the sealing ring 4 and the alignment groove 12 can be butted and fitted together.

[0026] Working principle: When in use, first pull the positioning rod 10 toward the end close to the return spring 9 until the positioning rod 10 and the alignment sleeve 14 are misaligned, and then release the positioning rod 10. At this time, the elasticity of the return spring 9 will drive the positioning rod 10 to move and reset quickly, causing the positioning rod 10 to be inserted into the interior of the alignment sleeve 14, so that the outer ring 13 can be installed on the outer ring of the metal pipe 15 to prevent the outer ring 13 from sliding again. After that, the metal head 5 can be moved to the top of the metal pipe 15 until the threaded rod 6 passes through the circular hole inside the top of the outer ring 13, so that the sealing ring 4 can enter the interior of the alignment groove 12, and then the nut 7 is screwed and installed on the outer ring of the threaded rod 6, and then the nut 7 is screwed to the bottom end of the outer ring 13 to tighten, so that the metal head 5 can be installed on the outer ring of the metal pipe 15. The metal head 5 is quickly installed on the top of the metal pipe 15. When the nut 7 is screwed to the limit position, the sealing ring 4 can be driven to fit with the alignment groove 12, so that leakage between the metal head 5 and the metal pipe 15 can be prevented, and the metal head 5 is quickly installed and positioned. When the metal head 5 needs to be separated from the metal pipe 15, the nut 7 can be screwed off the threaded rod 6, and then the metal head 5 can be pulled upward so that the metal head 5 can be separated from the metal pipe 15, which is convenient for the normal transmission of the metal pipe 15. After that, the positioning rod 10 can be pulled outward until the positioning rod 10 is moved out of the interior of the alignment sleeve 14, and then the outer ring ring 13 is pulled upward so that the outer ring ring 13 can be removed from the metal pipe 15, completing the disassembly of the outer ring ring 13.
