[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: A portable gas pressurization and airtightness testing machine solves the problem that existing gas pressurization and airtightness testing machines are large in size, which leads to the need to move the machine during testing, causing inconvenience in the transportation process and thus inconvenience in testing. The use of a base 1 improves the ease of use. The following is disclosed:

[0029] The top of the base 1 is fixed with a booster 2 by bolts; the right side of the booster 2 is provided with a handle 3, and the right side of the handle 3 is provided with a pressure gauge 4; the rear end of the base 1 is attached to a nitrogen cylinder 5, and the nitrogen cylinder 5 is connected to the booster 2 through a pipe; the surface of the nitrogen cylinder 5 is attached to a fixing rod 6, and the bottom of the fixing rod 6 extends into the interior of the base 1 to form a limiting mechanism.

[0030] refer to Figures 1 to 5When testing high-pressure components such as aerospace valves, the user can hold the handle on the base 1 to move the base 1 easily, facilitating subsequent testing. The base 1 is then connected to the aerospace valve via a pipeline. By turning the lever 3, the booster 2 can deliver gas from the nitrogen cylinder 5. The pressure gauge 4 can be used to observe the pressure, thus enabling the testing of the airtightness of the aerospace valve.

[0031] Example 2: A portable gas pressurization and airtightness testing machine solves the problem of inconvenience in replacing nitrogen cylinder 5 in existing systems. The use of a locking block 7 improves the ease of replacing nitrogen cylinder 5. The following is disclosed:

[0032] A locking block 7 is slidably connected to the bottom of the fixing rod 6, and the bottom of the outer end of the locking block 7 is arc-shaped. The outer end of the locking block 7 extends into the interior of the locking groove 8 to form a locking mechanism. The locking groove 8 is opened inside the base 1. The inner end of the locking block 7 is connected to a first spring 9, and the inner end of the first spring 9 is connected to the interior of the fixing rod 6. The inner end of the locking block 7 is connected to a pull rope 10, and the top of the pull rope 10 is slidably connected to the interior of the fixing rod 6. A roller 11 is attached to the bend of the pull rope 10, and the roller 11 is connected to the interior of the fixing rod 6 through a bearing.

[0033] refer to Figures 4 to 6 When nitrogen cylinder 5 needs to be replaced, pressing the top rod 12 causes it to slide inside the fixed rod 6. The movement of the top rod 12 compresses the pull rope 10 and the second spring 13, causing the second spring 13 to be compressed. The pull rope 10 then moves the locking block 7 via the roller 11, causing the locking block 7 to disengage from the locking groove 8. The movement of the locking block 7 compresses the first spring 9, causing the first spring 9 to be compressed. Then, pulling the fixed rod 6 causes it to disengage from the base 1, separating the fixed rod 6 from the nitrogen cylinder 5, allowing for easy disassembly of the nitrogen cylinder 5.

[0034] Example 3: A portable gas pressurization and airtightness testing machine solves the problem of the inconvenience of installing the fixing rod 6 in Example 2. The use of the clip 7 facilitates the installation of the fixing rod 6. The following is disclosed:

[0035] The top of the pull rope 10 is attached to the top rod 12, and the outer end of the top rod 12 extends into the interior of the fixed rod 6 to form a sliding mechanism. The top of the pull rope 10 is attached to the second spring 13, and the inner end of the second spring 13 is attached to the outer end of the top rod 12. The outer end of the second spring 13 is connected to the interior of the fixed rod 6.

[0036] refer to Figures 4 to 6When nitrogen cylinder 5 needs to be installed, the fixing rod 6 is attached to the base 1, and the bottom of the fixing rod 6 extends into the interior of the base 1. The fixing rod 6 then causes the locking block 7 to press against the base 1, which in turn causes the locking block 7 to be pressed into the fixing rod 6. The movement of the locking block 7 then compresses the first spring 9, which in turn compresses the first spring 9. After the fixing rod 6 moves to the position, the force of the first spring 9 pushes the locking block 7 into the slot 8 to form a lock, thus allowing the fixing rod 6 and the base 1 to lock together, thereby fixing the nitrogen cylinder 5.

[0037] Working principle: When using this portable gas pressurization and airtightness testing machine, firstly, refer to... Figures 1 to 5 When it is necessary to test high-pressure components such as aerospace valves, the user can hold the handle on the base 1 to move the base 1, which facilitates subsequent testing. Then, the aerospace valve is connected through the pipeline. By turning the handle 3, the pressure can be observed through the pressure gauge 4, which can then be used to test the airtightness of the aerospace valve.

[0038] refer to Figures 4 to 6 When nitrogen cylinder 5 needs to be replaced, pressing the top rod 12 causes it to slide inside the fixing rod 6. The movement of the top rod 12 compresses the second spring 13, causing the locking block 7 to move and disengage from the locking groove 8. Then, pulling the fixing rod 6 causes it to move and disengage from the base 1, separating the fixing rod 6 from the nitrogen cylinder 5, thus allowing the nitrogen cylinder 5 to be easily disassembled.

[0039] refer to Figures 4 to 6 When nitrogen cylinder 5 needs to be installed, the fixing rod 6 is attached to the base 1, and the bottom of the fixing rod 6 extends into the interior of the base 1. Then, the locking block 7 is pressed into the interior of the fixing rod 6. After the fixing rod 6 moves to the position, the force of the first spring 9 pushes the locking block 7 into the interior of the locking groove 8 to form a locking, so that the fixing rod 6 and the base 1 can be locked together, thus fixing the nitrogen cylinder 5.
