[0002] A gas cylinder refers to a type of movable pressure vessel with a bottle-shaped main structure, which is generally filled with gas (which can be compressed gas, liquefied gas, dissolved adsorbed gas, etc.). The storage device of the gas cylinder is usually made of metal or plastic. It can be used as a standardized transport container in cargo transportation to facilitate the unified loading and unloading and handover of goods. It generally refers to a gas cylinder group that is fixed by a special frame and uses a gas collecting pipe to connect multiple gas cylinder interfaces in parallel. When the gas cylinders are used up, they can be placed in the storage device and transported to a specific location for inflation. Generally, inflation is carried out one by one using an interface similar to that of a gas cylinder until inflation is completed.

[0029] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0030] like Figures 1 to 5 As shown, an inflating connection device for storing high-pressure gas cylinders according to an embodiment of the present invention comprises a container gas cylinder rack 1, wherein a first gas cylinder 11 is arranged inside the container gas cylinder rack 1, a gas cylinder valve 111 is arranged at the top of the first gas cylinder 11, and a gas charging connection port 112 is arranged on the side wall of the gas cylinder valve 111, and a first inflating valve 12 is symmetrically arranged at the top of the container gas cylinder rack 1, a first pipe 13 is fixedly installed on the side wall of the first inflating valve 12, a second pipe 14 is fixedly installed on the side wall of the first pipe 13, and an inflating component 2 is rotatably connected to the end of the second pipe 14;

[0031] like Figures 1 to 6As shown, the inflatable component 2 includes an inflatable rotating block 21 and a threaded rotating block 22, and the end of the inflatable rotating block 21 is rotatably installed with an anti-tilt device 3; the anti-tilt device 3 includes a first limit block 31, an alignment member 32 and a locking member 35, the threaded rotating block 22 is sleeved on the outer wall of the inflatable connecting port 112, so that the alignment member 32 slides inside the first limit block 31, the first limit block 31 moves, so that the locking member 35 aligns the threaded rotating block 22 with the inflatable connecting port 112, and the inflatable rotating block 21 is rotated so that the inflatable connecting port 112 will not tilt.

[0032] It should be noted that, when the gas cylinder is inflated, the gas cylinder interface needs to be connected to the pipeline interface, and metal connectors are generally used for normal connection. If the gas filled is oxygen, rubber pads cannot be added. Rubber pads will be greasy after use, and greasy dirt will spontaneously combust when encountering oxygen, thereby causing fire. When metal parts are used, the threaded opening on the inflation connection port 112 may be worn. Therefore, when the threaded rotating block 22 is rotated and engaged with the inflation connection port 112, it is not suitable to align them, and leakage may occur during the inflation process. In order to solve this problem, the following improvements are made:

[0033] First, multiple first gas cylinders 11 are arranged at the same interval inside the container gas cylinder rack 1, and the number of the first gas cylinders 11 is the same as the number of the second pipes 14. Then, the inflation rotating block 21 and the threaded rotating block 22 on the second pipe 14 are moved close to the inflation connection port 112 on the first gas cylinder 11. In the initial state, the threaded rotating block 22 is located at the farthest end away from the first limit block 31, and the locking piece 35 is located at the farthest end away from the center of the first limit block 31, and the alignment piece 32 is located at the farthest end away from the first limit block 31, so that the alignment piece 32 is close to the side wall of the gas cylinder valve 111. Then, the inflation rotating block 21 is held so that the inflation rotating block 21 continues to move toward the center of the gas cylinder valve 111. During the movement, the alignment piece 32 slides on the first limit block 31. The locking piece 35 is moved inside the first limit block 31, thereby driving the locking piece 35 to rotate and approach the center position of the first limit block 31, and the locking piece 35 approaches the outer wall of the inflation connection port 112 while approaching, until the inflation connection port 112 is completely clamped by the locking piece 35, the threaded rotating block 22 will not tilt during the rotation and movement, so that the threaded rotating block 22 can engage with the inflation connection port 112, and the threaded rotating block 22 is moved to approach the end of the inflation connection port 112. The inflation rotating block 21 can be rotated to the outer wall of the inflation connection port 112 to complete the installation of the threaded rotating block 22 and the inflation connection port 112, and then the first inflation valve 12 is connected to the inflation pipe for inflation, and it can be disassembled until the inflation is completed.

[0034] like Figure 5 to Figure 6 As shown, the inflation component 2 includes a threaded rotating block 22 rotatably installed at the end of the second pipe 14, an inflation rotating block 21 is arranged on the outside of the threaded rotating block 22, a first slide groove 23 is arranged inside the inflation rotating block 21, a first slider 24 is slidably installed on the inner wall of the first slide groove 23, one end of the first slider 24 is fixedly installed on the outer wall of the threaded rotating block 22, and a lever 25 is fixedly installed on the other end of the first slider 24, and the lever 25 is used to rotate the threaded rotating block 22.

[0035] It should be noted that when the first limit block 31, the alignment piece 32 and the locking piece 35 align the center position of the inflatable rotating block 21 with the center position of the inflatable connecting port 112, the first slider 24 and the threaded rotating block 22 can be driven to slide on the inner wall of the first slide groove 23 by moving the lever 25, so that the threaded rotating block 22 always maintains the horizontal movement at the center position of the inflatable rotating block 21, and then by holding the lever 25, when the threaded rotating block 22 is rotated to a certain force, the threaded rotating block 22 can be rotated by the lever 25 to achieve a tightening effect, thereby preventing the threaded rotating block 22 from tilting when it engages with the inflatable connecting port 112.

[0036] like Figures 5 to 7 As shown, the anti-tilt device 3 includes a first limit block 31 rotatably installed at the end of the first slide groove 23, the first limit block 31 is provided with a second slide groove 311 and a third slide groove 312, the second slide groove 311 is provided with an alignment member 32, the first limit block 31 is provided with a locking member 35, and the third slide groove 312 is provided with a limit member 33. The alignment member 32 is extended and retracted to drive the locking member 35 to align and center the inflation connection port 112, and the limit member 33 is used to lock the alignment member 32 when it moves.

[0037] It should be noted that when the alignment member 32 slides inside the second slide groove 311, it can drive the locking member 35 to rotate, thereby clamping the outer wall of the inflation connection port 112, thereby achieving the effect of aligning the threaded rotating block 22 with the inflation connection port 112, and then locking the position of the alignment member 32 through the limit member 33 to prevent the first limit block 31 from shaking and tilting when the threaded rotating block 22 approaches the inflation connection port 112.

[0038] like Figure 6 to Figure 7As shown, the alignment member 32 includes a first slide rod 322 slidably installed inside the second slide groove 311, a first extrusion block 321 is fixedly installed on the end of the first slide rod 322, a second spring 325 is fixedly installed on the side wall of the first extrusion block 321, the second spring 325 is concentric with the first slide rod 322, and a first tooth 323 and a second tooth 324 are arranged inside the first slide rod 322, the second tooth 324 is used to engage with the locking member 35, and the first tooth 323 is used to engage with the limit member 33.

[0039] It should be noted that when the inflatable rotating block 21 drives the first limit block 31 to continue to approach the position of the first extrusion block 321, the first tooth 323 on the first slide rod 322 engages with the limit member 33, thereby unidirectionally locking the positions of the first limit block 31 and the first extrusion block 321, and the second tooth 324 engages with the locking member 35 during the movement, thereby driving the locking member 35 to approach the outer wall of the inflatable connecting port 112, thereby clamping and aligning, so that when the threaded rotating block 22 engages close to the inflatable connecting port 112, no tilting will occur.

[0040] like Figures 7 and 8 As shown, the limiting member 33 includes a second sliding rod 334 slidably installed inside the third sliding groove 312, the outer wall of the second sliding rod 334 is symmetrically installed with a third sliding column 335, the outer wall of the second sliding rod 334 is slidably installed with a first rotating block 331, the interior of the first rotating block 331 is provided with a fourth sliding groove 332, the interior of the fourth sliding groove 332 is provided with a fifth sliding groove 333, the second sliding rod 334 slides inside the fourth sliding groove 332, the third sliding column 335 slides inside the fifth sliding groove 333, the first rotating block 331 rotates to drive the second sliding rod 334 to approach the center of the first rotating block 331, and the end of the second sliding rod 334 engages with the first tooth 323 to lock the first sliding rod 322.

[0041] It should be noted that, considering that the first limit block 31 moves, the distance between the first limit block 31 and the first extrusion block 321 is reduced, and the reduced distance needs to be locked to prevent the threaded rotating block 22 from tilting when it contacts the inflation connection port 112. Therefore, a fourth slide groove 332 and a fifth slide groove 333 are provided inside the first rotating block 331. Rotating the first rotating block 331 can make the second slide bar 334 approach or move away from the center of the first limit block 31, and the second slide bar 334 slides inside the limit member 33, which can make the second slide bar 334 slide inside the first rotating block 331, and the end of the second slide bar 334 engages with the first tooth 323. Therefore, the second slide bar 334 can be adjusted to slide inside the first rotating block 331 by rotating the first rotating block 331.

[0042] like Figures 7 and 8 As shown, a first fixed column 34 is fixedly installed on the outer wall of the first limit block 31, a groove is opened inside the first rotating block 331 to accommodate the upper part of the first fixed column 34, and a first spring 341 is fixedly installed on the side wall of the first fixed column 34, and the end of the first spring 341 is fixedly installed inside the first rotating block 331.

[0043] It should be noted that, considering that during use, the first rotating block 331 can automatically engage the second sliding rod 334 with the first tooth 323, a first fixed column 34 is provided on the outer wall of the first limit block 31, and a first spring 341 is provided on the side wall of the first fixed column 34, so that the first rotating block 331 is in a normal situation, the second sliding rod 334 and the first tooth 323 are in an engaged state, and the effect of resetting the alignment member 32 can be achieved by rotating the first rotating block 331 so that the first rotating block 331 and the first limit block 31 are staggered by a certain angle.

[0044] like Figures 7 and 8 As shown, the locking member 35 includes a first gear 352 rotatably mounted inside the first limit block 31, the first gear 352 has a first threaded rod 351 installed on its internal thread, the side wall of the first gear 352 is meshed with the second tooth 324, and a clamping wheel 353 is rotatably mounted on the end of the first threaded rod 351.

[0045] It should be noted that when the first sliding rod 322 slides inside the second sliding groove 311, the second tooth 324 is in a meshing state with the first gear 352, thereby driving the first gear 352 to rotate. The rotation of the first gear 352 can drive the first threaded rod 351 to approach the center of the first limit block 31, and a clamping wheel 353 is provided at the end of the first threaded rod 351, so as to clamp and align the outer wall of the inflation connection port 112, thereby preventing the threaded rotating block 22 from rotating to the inflation connection port 112 and causing tilting when meshing.

[0046] like Figure 7 As shown, the inflation rotating block 21 is concentric with the first limiting block 31 and the first extruding block 321 .

[0047] It should be noted that the inflation rotating block 21 is concentric with the first limiting block 31 and the first extrusion block 321, so that when the threaded rotating block 22 rotates and moves, it will not tilt with the inflation connecting port 112 to cause the phenomenon of non-engagement and air leakage.

[0048] like Figures 6 to 8 As shown, the second sliding rod 334 and the first gear 352 are installed alternately inside the first limiting block 31 .

[0049] It should be noted that the second slide bar 334 and the first gear 352 are staggeredly installed inside the first limit block 31. When the first slide bar 322 slides inside the first limit block 31, the second tooth 324 engages with the second spring 325, and the first tooth 323 engages with the second slide bar 334.

[0050] like Figures 6 to 8 As shown, the diameter of the first extrusion block 321 is smaller than the length of the gas cylinder valve 111 .

[0051] It should be noted that the diameter of the first extrusion block 321 is smaller than the length of the gas cylinder valve 111 , so that the gas cylinder valve 111 can lift up the first extrusion block 321 .

[0052] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
