[0020] Embodiment

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in [relevant figures], the technical solution in the embodiment of the present application effectively solves the technical problem that the airtightness is measured by a detection head, but the detection result may be affected by environmental factors, and the detected data is easily affected at different temperatures or humidities, affecting the accuracy of the detection. The general idea is as follows:

[0022] In view of the problems existing in the prior art, the present utility model provides a PRO gas cylinder airtightness detection device, including a detection tank 11 and a fixing frame 12. Two mounting blocks 13 are fixedly installed inside the fixing frame 12. A support plate 14 is slidably installed inside the fixing frame 12. At least two second clamping plates 21 are fixedly installed at the side end of the support plate 14. At least two first clamping plates 19 are slidably installed at the side end of the support plate 14. By moving the first clamping plate 19 to expand the internal spacing and moving the gas cylinder body 15, the gas cylinder body 15 is placed between the first clamping plate 19 and the second clamping plate 21. Since the first clamping plate 19 is adjustable, gas cylinder bodies 15 of different sizes can be clamped and fixed. At least two second telescopic rods 25 are fixedly installed at the bottom end of the support plate 14. The top ends of the two second telescopic rods 25 are fixedly installed with the same bottom plate 27. A gas cylinder body 15 is disposed inside each first clamping plate 19.

[0023] A slider 23 is fixedly installed at the side end of each first clamping plate 19, a side plate 24 is fixedly installed at the top end of each first clamping plate 19, a first telescopic rod 22 is fixedly installed at the side end of each second clamping plate 21, a second connecting pipe 26 is fixedly installed at the top end of each bottom plate 27, a docking head 28 is fixedly installed at the top end of each bottom plate 27, and a first connecting pipe 18 is fixedly installed at the bottom end of each mounting block 13. Through the transmission of the first connecting pipe 18 and the second connecting pipe 26, high-pressure air is delivered into the interior of the cylinder body 15 through the docking head 28. By controlling the downward stretching of the driving rod 17, the top end of the driving rod 17 exerts a downward force on the support plate 14, causing the support plate 14 to drive a plurality of cylinder bodies 15 into the interior of the detection groove 11, submerging the lower half of the cylinder body 15 in the water source inside the detection groove 11, and detecting airtightness through the generated bubbles. A connecting head 16 is fixedly installed at the side end of each mounting block 13, a driving rod 17 is fixedly installed inside each fixing frame 12, and a plurality of sliding grooves are formed at the side end of the support plate 14, and the sliding grooves are fitted with the sliders 23.

[0024] Working principle:

[0025] First step, before use, input water source into the interior of the detection groove 11. By driving the first telescopic rod 22 to expand and contract at the side end of the second clamping plate 21, the side end of the first telescopic rod 22 is fixedly connected to the support plate 14, and the first telescopic rod 22 exerts a horizontal thrust on the first clamping plate 19, causing the first clamping plate 19 to slide at the side end of the support plate 14. At the same time, the first clamping plate 19 drives the slider 23 to move inside the sliding groove at the side end of the support plate 14. The slider 23 plays a guiding role for the first clamping plate 19. At the same time, by moving the first clamping plate 19, the internal distance is enlarged, and the cylinder body 15 is moved to place the cylinder body 15 between the first clamping plate 19 and the second clamping plate 21. Since the first clamping plate 19 is adjustable, it can clamp and fix cylinder bodies 15 of different sizes, increasing the flexibility of use.

[0026] Step 2: By driving the first telescopic rod 22 to stretch reversely, a pulling force is applied to the first clamping plate 19, enabling the first clamping plate 19 to slide at the side end of the first telescopic rod 22, and enabling the side plate 24 to clamp and fix the steel cylinder. Meanwhile, by driving the second telescopic rod 25 to expand and contract at the bottom end of the support plate 14, the second telescopic rod 25 pulls the bottom plate 27 upward, enabling the bottom plate 27 to squeeze and expand the second connecting pipe 26. Meanwhile, the bottom plate 27 drives the docking head 28 to dock with the top end of the steel cylinder body 15. High-pressure air is input through the interface at the side end of the mounting block 13. Through the transmission of the first connecting pipe 18 and the second connecting pipe 26, the high-pressure air is conveyed into the interior of the steel cylinder body 15 through the docking head 28. By controlling the driving rod 17 to stretch downward, the top end of the driving rod 17 generates a downward acting force on the support plate 14, enabling the support plate 14 to drive multiple steel cylinder bodies 15 into the interior of the detection groove 11, submerging the lower half of the steel cylinder body 15 in the water source inside the detection groove 11, and detecting the airtightness through the generated bubbles, without being affected by the external environment, and enabling the detection of multiple steel cylinder bodies 15 simultaneously.

[0027] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly explaining the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
