[0002] Cylinders are steel cylinders used to store high-pressure oxygen, coal gas, liquefied petroleum gas, etc. Gas cylinders generally contain permanent gases, liquefied gases, or mixed gases. The management of gas cylinders by gas cylinder filling units, gas cylinder inspection units, gas cylinder users (including factories, laboratories, hospitals, schools, disease control centers, electronic rooms, clean rooms, industrial institutions, etc.), bottled gas, and gas cylinder distributors needs to be improved urgently, and the safety management of the transportation and storage of gas cylinders should be strengthened.

[0003] When the existing vertical steel cylinder is in use, the valve of the steel cylinder is connected to the liquid submerged pipe by welding. The valve of the steel cylinder is a copper valve, and the liquid submerged pipe is a 304 stainless steel capillary tube with a spacing of 20 mm from the bottom of the bottle. The shaking of the steel cylinder during the transportation of the full bottle and the vibration when the bottle is empty have a great impact on the liquid submerged pipe. At the same time, due to the different materials of the valve and the liquid submerged pipe, it is easy to cause the welding joint to break. After the welding joint is cracked, the liquid submerged pipe falls off immediately, making it impossible to unload the steel cylinder. Utility Model Content

[0024] The locking cam 413 is then engaged with the locking cam 414 and the locking cam 415 is engaged with the locking cam 416. The locking cam 416 is engaged with the locking cam 417 and the locking cam 418 is engaged with the locking cam 419.

[0025] Specifically, the pull rod 46 and the movable rod 47 are an integrated structure, and a slot is provided inside the submersible tube 7 corresponding to the positioning plug 48 .

[0026] By adopting the above technical solution, the use strength of the pull rod 46 and the movable rod 47 is improved, and the service life of the equipment is guaranteed.

[0027] Specifically, the positioning device 41 includes a damping shaft 411, a connecting rod 412, a clamping block 413 and a positioning seat 414, wherein a damping shaft 411 is provided at the upper end of the pull rod 46, a connecting rod 412 is provided on one side of the damping shaft 411, a clamping block 413 is provided on one side of the connecting rod 412, and two groups of positioning seats 414 are provided at the upper end of the mounting seat 44 corresponding to the clamping block 413.

[0030] Example 2

[0031] The present embodiment is different from the embodiment 1 in that: specifically, the buffer protection assembly 5 includes a mounting plate 51, a fixing seat 52, a buffer spring 53, a telescopic rod 54, a through hole 55 and a damping ring 56, wherein a fixing seat 52 is provided at the inner bottom end of the cylinder body 6, a telescopic rod 54 is provided in the middle of the inner part of the fixing seat 52, a buffer spring 53 is sleeved on the surface of the telescopic rod 54, a mounting plate 51 is provided at the upper end of the telescopic rod 54, a damping ring 56 is provided on the surface of the mounting plate 51, and a through hole 55 is provided on the inner wall surface of the fixing seat 52.

[0032] By adopting the above technical solution, when the cylinder body 6 vibrates during transportation, the bottom end of the submersible tube 7 abuts against the upper end of the damping ring 56, so that the damping ring 56 and the mounting plate 51 are forced to move downward, and at the same time, the telescopic rod 54 contracts and the buffer spring 53 is forced to vibrate, and the elastic potential energy generated is released by the friction between the damping ring 56 and the inner wall of the fixing seat 52, thereby improving the shock absorbing effect of the submersible tube 7, ensuring the stability of transportation, and preventing the submersible tube 7 from being damaged.

[0033] Specifically, the damping ring 56 is one centimeter higher than the upper end surface of the mounting plate 51 .

[0034] By adopting the above technical solution, when the submersible tube 7 is in use, since there is a gap between the bottom end of the submersible tube 7 and the mounting plate 51, and a through hole 55 is provided on the inner wall surface of the fixing seat 52, stable liquid inflow is ensured to prevent poor liquid inflow.

[0035] When this embodiment is in use: when the cylinder body 6 vibrates during transportation, the bottom end of the submersible tube 7 abuts against the upper end of the damping ring 56, so that the damping ring 56 and the mounting plate 51 are forced to move downward, and at the same time, the telescopic rod 54 contracts and the buffer spring 53 is forced to vibrate, and the elastic potential energy generated is released by the friction between the damping ring 56 and the inner wall of the fixing seat 52, thereby improving the shock absorption effect of the submersible tube 7, ensuring the stability of transportation, and preventing the submersible tube 7 from being damaged. When the submersible tube 7 is in use, there is a gap between the bottom end of the submersible tube 7 and the mounting plate 51, and the inner wall surface of the fixing seat 52 is provided with a through hole 55, which ensures that the liquid inflow is stable and prevents the occurrence of poor liquid inflow.

[0036] The working principle and use process of the utility model are as follows: when the submerged pipe 7 is installed, the connecting rod 412 is first rotated along the damping rotating shaft 411, and then the clamping block 413 is inserted into the positioning seat 414 on the left side of the mounting seat 44 for installation. At this time, the positioning plug 48 is received in the interior of the mounting seat 44 and the limit spring 45 is compressed by force. Then the submerged pipe 7 and the threaded pipe sleeve 3 are screwed and installed accordingly. When the submerged pipe 7 is installed in place, the clamping block 413 is taken out from the positioning seat 414. At this time, the limit spring 45 is reset to push the positioning plug 48 to insert the clamping groove inside the submerged pipe 7 to limit it, preventing the submerged pipe 7 from loosening, ensuring the stability and firmness of the installation of the submerged pipe 7, and then the connecting rod 412 is rotated again to clamp the clamping block 413 into the positioning seat 414 on the right side of the upper end of the mounting seat 44 for installation, preventing vibration from causing the limit spring 45 to be forced to shake and affect the limiting effect of the positioning plug 48, thereby improving the use strength of the equipment, ensuring the use quality of the equipment, and preventing the submerged pipe 7 from breaking.

[0037] When the cylinder body 6 vibrates during transportation, the bottom end of the submersible tube 7 abuts against the upper end of the damping ring 56, causing the damping ring 56 and the mounting plate 51 to move downward under force. At the same time, the telescopic rod 54 contracts and the buffer spring 53 vibrates under force. The elastic potential energy generated is released by the friction between the damping ring 56 and the inner wall of the fixing seat 52, thereby improving the shock absorption effect of the submersible tube 7, ensuring the stability of transportation, and preventing the submersible tube 7 from being damaged. When the submersible tube 7 is in use, there is a gap between the bottom end of the submersible tube 7 and the mounting plate 51, and the inner wall surface of the fixing seat 52 is provided with a through hole 55, which ensures that the liquid inlet is stable and prevents the occurrence of poor liquid inlet.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
