[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Combined with the attached Figure 1 and Figure 5 , a medical oxygen cylinder valve calibration device includes a calibration table and a connector (2) that is threadedly engaged with the bottom end of the cylinder valve body. A plurality of connecting rods are respectively connected to the circumference of the calibration table (1), and the other ends of the connecting rods are hingedly provided with mounting seats (4). Mounting holes (5) are respectively connected to the mounting seats (4), and the mounting holes (5) are threadedly engaged with the connector (2). An inflation and pressurization assembly (6) is connected to the middle of the calibration table (1), and the output end of the inflation and pressurization assembly (6) is connected with a shunt pipe (7). The other end of the shunt pipe (7) is connected to the connector (2) through a flexible pipe.

[0025] After the connector (2) is stably threadedly connected to the cylinder valve body, the inflation and pressurization assembly (6) can be used to simultaneously inflate and detect each cylinder valve.

[0026] Combined with the attached Figure 3 and Figure 4, a limiting component for limiting and clamping the bottle valve body is connected to the mounting base (4). The limiting component includes a cavity connected to the mounting base (4). A first bevel gear (8) is rotatably connected in the cavity. A driving shaft is connected to the first bevel gear (8). The driving shaft rotates through the cavity and a knob (9) is connected to the other end. Second bevel gears (10) are rotatably connected on both sides of the first bevel gear (8) in the cavity. The second bevel gears (10) are meshed with the first bevel gear (8). Screws (11) are respectively connected inside the second bevel gears (10). The other end of the screw (11) is rotatably connected to the cavity. A slider (12) is slidably connected in the cavity. The screw (11) passes through the slider (12) through threads. A clamping plate (13) is connected to the slider (12). The clamping plate (13) is circumferentially matched with the bottle valve body. The clamping plate (13) is concentric with the mounting hole (5).

[0027] The arrangement of the limiting component facilitates the clamping and limiting of the bottle valve body, and the concentric setting of the mounting hole (5) and the clamping plate (13) enables the clamped and limited bottle valve body to be aligned with the joint (2), facilitating subsequent thread fitting.

[0028] Combined with the attached Figure 5 and Figure 6 , a driving component for driving the joint (2) to be in thread fit with the bottle valve body is connected to the calibration table (1). The driving component includes a first gear (14) rotatably connected to the bottom end of the mounting base (4) and a linkage component for simultaneously driving each first gear (14) to rotate in the same direction. The joint (2) is connected to the inside of the first gear (14) through threads; the linkage component includes a motor (15) connected inside the calibration table (1). A second gear (16) is connected to the power output end of the motor (15). A sleeve (17) is slidably connected circumferentially to the calibration table (1). An internal gear ring (18) and an external gear ring (19) are connected to the sleeve (17). The internal gear ring (18) is meshed with the second gear (16). The external gear ring (19) is meshed with the first gear (14) passing through the mounting base (4).

[0029] By starting the motor (15), the motor (15) drives the second gear (16). The second gear (16) drives the sleeve (17) through the meshing with the internal gear ring (18). The sleeve (17) drives the first gear (14) to rotate through the meshing of the external gear ring (19) and each first gear (14). The first gear (14) drives the joint (2) to rotate and rise while being in thread fit with the joint (2), thereby facilitating the thread fit between the joint (2) and the limited bottle valve body.

[0030] Combined with the attached Figure 2, a transparent water tank (3) is provided at the bottom of the calibration table (1). An underwater component for driving the mounting seat (4) to perform an immersion test is connected to the calibration table (1). The underwater component includes a slip ring (20) slidably connected to the calibration table (1). A ring groove is connected to the calibration table (1). The slip ring (20) is slidably connected to the ring groove. A fixed column (21) is connected to the calibration table (1). A telescopic cylinder (22) is hinged between the fixed column (21) and the slip ring (20). The circumferential direction of the slip ring (20) is hinged with a hinge rod (23) through a ball joint. The other end of the hinge rod (23) is hinged to the top of the mounting seat (4) through a ball joint.

[0031] By driving the telescopic cylinder (22) to drive the slip ring (20) to slide along the ring groove, the slip ring (20) drives the mounting seat (4) to rotate around the hinge joint with the connecting rod through the hinge rod (23). The mounting seat (4) drives the connected valve body to be immersed in water. The air bubble distribution at the connecting part of the valve body can be used to test its sealing performance.

[0032] The specific usage method is as follows:

[0033] First, place the bottom end of the valve body into the mating mounting hole (5). The mounting hole (5) is a stepped hole. The top of the mounting hole (5) facilitates positioning the bottom end of the valve body, while the bottom of the mounting hole (5) facilitates the penetration of the joint (2) and its threaded connection with the valve body.

[0034] Then, limit the valve body through the limiting component to prevent the valve body from shifting during the connection with the joint (2). By rotating the knob (9) to drive the first bevel gear (8), the first bevel gear (8) drives the screw rod (11) through meshing with the second bevel gear (10). The screw rod (11) drives the slider (12) to move closer to each other through threaded cooperation with the slider (12), thereby facilitating stable limitation of the valve body.

[0035] Next, start the motor (15). The motor (15) drives the second gear (16). The second gear (16) drives the sleeve (17) through meshing with the internal gear ring (18). The sleeve (17) drives the first gear (14) to rotate through meshing of the external gear ring (19) and each first gear (14). The first gear (14) drives the joint (2) to rotate and rise through threaded cooperation with the joint (2), thereby facilitating the threaded cooperation between the joint (2) and the limited valve body.

[0036] After the bottle valve body and the joint (2) are in threaded sealing fit, the telescopic cylinder (22) can be started. The telescopic cylinder (22) drives the sliding ring (20) to slide along the annular groove. The sliding ring (20) drives the mounting seat (4) to rotate around the hinge point with the connecting rod through the hinge rod (23). The mounting seat (4) drives the connected bottle valve body to be completely immersed in water. Finally, the air flow is introduced into the bottle valve body through the inflation and pressurization assembly (6) in sequence through the shunt pipe (7), the flexible pipe, and the joint (2). The airtightness is tested by observing whether bubbles are generated in the water at the connection of each bottle valve body.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
