[0035] As shown in Figure 4 , the downward mechanism 1 includes a pressing plate 13, the pressing plate 13 is connected with a downward cylinder 14, the downward cylinder 14 drives the longitudinal movement of the pressing plate 13, the downward cylinder 14 is fixed on the supporting frame 12, the supporting frame 12 includes a supporting plate 53 and a supporting column, the supporting column is fixed on the machine frame table. In the downward process, the downward cylinder 14 drives the longitudinal downward movement of the pressing plate 13, and the pressing plate 13 and the machine frame table form a space for accommodating the medical bag.

[0036] As shown in Figure 10 , the aligning mechanism 5 includes an aligning plate 9, the aligning plate 9 is connected with an aligning cylinder one 10, the aligning cylinder one 10 is connected with an aligning cylinder two 11, the aligning cylinder two 11 is fixed on the machine frame table through an aligning support 63.

[0037] As shown in Figure 3 , 4 , the pressing plate 13 is fixed with a guide assembly 16, the guide assembly 16 includes a guide shaft 55 and a guide sleeve 56, the lower end of the guide shaft 55 is fixed on the pressing plate 13, the guide shaft 55 and the guide sleeve 56 are slidingly connected, and the guide sleeve 56 is fixed on the supporting plate 53.

[0038] As shown in Figure 4 , 5 , the pipe pressing assembly 4 includes a pipe pressing plate 6, the pipe pressing plate 6 is connected with a pipe pressing cylinder 7, the pipe pressing cylinder 7 is fixed on a pipe pressing supporting block 8, in the pipe pressing process, the pipe pressing cylinder 7 drives the longitudinal movement of the pipe pressing plate 6, the pipe body 22 is pressed by the pipe pressing plate 6, the position of the pipe body 22 is limited from Z direction, avoiding that the pipe body 22 is tilted or swings.

[0039] More specifically, the pressing plate 13 comprises a pressing plate one 17 and a pressing plate two 18 fixedly connected, the pressing pipe assembly 4 is fixed on the pressing plate two 18, the pressing plate two 18 is provided with a groove 19 matched with the pressing pipe plate 6, the pressing pipe plate 6 comprises a connecting part 20 and a pressing pipe part 21, the pressing pipe part 21 protrudes from the pressing plate one 17 and the pressing plate two 18, when the pressing pipe cylinder 7 drives the pressing pipe plate 6 to move downward, the connecting part 20 extends into the groove 19, and the pressing pipe part 21 presses the pipe body 22. The position of the pipe body 22 is limited from the Z direction.

[0040] As shown in the figure, Figure 6 The catheter positioning mechanism 2 comprises a clamping jaw one 23 and a clamping jaw two 24 connected with a clamping cylinder 25, and the clamping cylinder 25 is connected with a positioning cylinder 26.

[0041] In the catheter positioning process, the positioning cylinder 26 drives the clamping jaw one 23 and the clamping jaw two 24 to move downward in the longitudinal direction, and the clamping cylinder 25 drives the clamping jaw one 23 and the clamping jaw two 24 to clamp the pipe body 22 from both sides, i.e. to limit the position of the pipe body 22 from the X direction, so as to position the pipe body 22.

[0042] As shown in the figure, Figure 7 , 8 The clamping jaw one 23 is provided with a clamping hole one 27, an upper guide surface one 28 and a lower guide surface one 29, the clamping jaw two 24 is provided with an insert block one 30 matched with the clamping jaw one 23, the clamping jaw two 24 is provided with a clamping hole two 31, an upper guide surface two 32 and a lower guide surface two 33, the clamping jaw one 23 is fixedly connected with an insert block two 34 matched with the clamping jaw two 24, and the clamping jaw one 23 is further fixedly connected with a pipe blocking plate 35. Through the structural design of the clamping jaw one 23 and the clamping jaw two 24, the clamping jaw one 23 and the clamping jaw two 24 can be precisely clamped, and misalignment can be avoided.

[0043] As shown in the figure, the aligning mechanism 5 limits the position of the pipe body 22 from the Y direction, the pressing pipe assembly 4 limits the position of the pipe body 22 from the Z direction, and the catheter positioning mechanism 2 limits the position of the pipe body 22 from the X direction. The aligning mechanism 5, the pressing pipe assembly 4 and the catheter positioning mechanism 2 are matched with each other, so that the pipe body 22 is in a preset position, which is beneficial to the accurate insertion of the pipe body 22 into the gas measurement mechanism 3.

[0044] As shown in the figure, Figure 9 The gas measurement mechanism 3 comprises a gas measurement head 36 connected with a sliding table cylinder 37, the sliding table cylinder 37 is slidingly connected with an adjusting plate 38, the sliding table cylinder 37 is connected with a single rod cylinder 39 fixed on the adjusting plate 38. The adjusting plate 38 is provided with a limiting assembly 60 limiting the movement of the single rod cylinder 39, and the limiting assembly 60 comprises a limiting block 61 and a buffer assembly 62. The limiting assembly 60 limits the operation of the single rod cylinder 39, so as to avoid position deviation caused by over operation.

[0045] In the process of inserting the pipe body 22 into the gas testing head 36, the single-rod cylinder 39 first drives the gas testing head 36 to move towards the pipe body 22 in the Y direction, and then the slide table cylinder 37 drives the gas testing head 36 to continue to move in the Y direction. The slide table cylinder 37 has high precision and runs more stably, and the single-rod cylinder 39 is suitable for long stroke, has low price, simple structure and flexible use. The combination of the two can realize long stroke driving and high precision and stable running, which is beneficial to the accurate insertion of the pipe body 22 into the gas testing head 36.

[0046] When detecting the air tightness of the medical bag, the space formed between the pressing plate 13 and the rack table top for accommodating the medical bag must be stable, otherwise, the air pressure in the medical bag will be unstable due to the upward or downward movement of the pressing plate 13, thereby causing false detection results. Therefore, the locking assembly 40 is additionally arranged on the pressing mechanism 1.

[0047] As shown in Figure 11 The locking assembly 40 comprises a limiting column assembly 41 and a limiting block 42. The limiting column assembly 41 is connected with a driving cylinder 43, the driving cylinder 43 is fixed on a locking fixing plate 44, the locking fixing plate 44 is fixed on the guide assembly 16, the limiting block 42 is fixed on the support frame 12, and the locking fixing plate 44 is provided with an opening 45 through which the limiting block 42 passes.

[0048] After the downward movement of the pressing plate 13 driven by the downward pressing cylinder 14, the locking fixing plate 44 fixedly connected with the guide shaft 55 moves downward relative to the support plate 53, the limiting block 42 passes through the opening 45, and a limiting space is formed between the limiting block 42 and the locking fixing plate 44. The driving cylinder 43 drives the limiting column assembly 41 to insert into the limiting space, the upper end of the limiting column assembly 41 abuts against the limiting block 42, and the lower part of the limiting column assembly 41 abuts against the locking fixing plate 44, so as to lock the pressing plate 13. The pressing plate 13 is not prone to upward or downward movement during the gas testing process, thereby ensuring the accuracy of the air tightness detection result.

[0049] The limiting column assembly 41 comprises a connecting block 47 and a locking block 48 which are stacked in the longitudinal direction. The connecting block 47 is provided with a mounting hole 49, the mounting hole 49 is slidably mounted with a limiting column 50, the upper end of the limiting column 50 is provided with a flange 51, a spring 52 is sleeved on the limiting column 50, and one end of the spring 52 abuts against the flange 51. The spring 52 provides buffering during locking, thereby avoiding jamming.

Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the present application or exceeding the scope defined by the appended claims.
