[0040] The rotating member 21 includes a fixed cylinder 211, which is fixedly connected to the middle part of the top plate of the support frame 1, and a rotating cylinder 212 is rotatably connected to the outer wall of the fixed cylinder 211.

[0042] The air supply pipe 221 is connected to the interior of the fixed cylinder 211 through the air supply hole 223, and the air extraction pipe 222 is connected to the interior of the fixed cylinder 211 through the air extraction hole 224;

[0043] The detection assembly 3 includes an isolation assembly 31. The ends of the air supply pipe 221 and the air extraction pipe 222 away from the drum 212 are connected to the isolation assembly 31. The end of the isolation assembly 31 away from the drum 212 is connected to a material containing closure 32.

[0044] The isolation assembly 31 includes a detection box 311. The ends of the air supply pipe 221 and the air extraction pipe 222 away from the rotating drum 212 are fixedly connected to the detection box 311. A connecting plug 312 is fixedly connected to the side wall of the detection box 311. The connecting plug 312 is connected to the air supply pipe 221, and the air extraction pipe 222 is connected to the interior of the detection box 311.

[0045] The material holding and closing member 32 includes an L-shaped slide 321. The L-shaped slide 321 is slidably connected to the end of the detection box 311 away from the connecting plug 312. The inner top of the L-shaped slide 321 is fixedly connected to a material holding trough 322. The interior of the material holding trough 322 is clamped with a detection object 323. The end of the detection object 323 near the connecting plug 312 is provided with a 324, and the connecting plug 312 is clamped with 324.

[0046] The limiting linkage assembly 4 includes a linkage assembly 41. The top of the support frame 1 is connected to the linkage assembly 41. The L-shaped slide 321 and the side wall of the detection box 311 away from the rotating drum 212 are connected to a limiting guide 42.

[0047] The linkage assembly 41 includes a special-shaped chute 411. The top of the support frame 1 is provided with a special-shaped chute 411. The bottom of the L-shaped slide 321 is fixedly connected with a linkage slider 412. The linkage slider 412 is slidably connected in the special-shaped chute 411.

[0048] The special-shaped chute 411 is composed of a circular chute and a convex chute;

[0049] The limiting guide member 42 includes a limiting slide 421. The limiting slide 421 is fixedly connected to the side wall of the L-shaped slide 321 away from the rotating drum 212. A sliding rod 422 is fixedly connected to the side wall of the detection box 311 away from the rotating drum 212. The sliding rod 422 passes through the limiting slide 421 and is slidably connected to the limiting slide 421.

[0050] When the inspection object 323 needs to be inspected, the inspection object 323 is placed in the material trough 322, and the motor 215 is started. The motor 215 drives the driven gear 213 to rotate through the driving gear 214, and the driven gear 213 drives the rotating drum 212 to rotate. The rotating drum 212 drives the inspection box 311 and the L-shaped slide 321 to rotate around the fixed cylinder 211 through the air supply pipe 221 and the exhaust pipe 222. The L-shaped slide 321 drives the linkage slide 412 to rotate around the fixed cylinder 211. At this time, the L-shaped slide 321 is driven to rotate under the limit of the convex slide part of the special-shaped slide 411 under the limit of the limit slide 421 and the slide rod 422. When the linkage slider 412 enters the arc-shaped slot of the special-shaped slot 411, the L-shaped slide 321 and the detection box 311 are combined into a closed whole. At this time, the L-shaped slide 321 drives the detection object 323 through the material receiving slot 322 to move toward the connection plug 312 and make 324 engage with the connection plug 312. At this time, the detection object 323 is automatically connected and closed. When the detection object 323 needs to be removed, the linkage slider 412 can be rotated one circle so that the linkage slider 412 returns to the starting position, thereby realizing the automatic closure and ejection of the detection object 323.

[0051] When the exhaust pipe 222 rotates to connect with the exhaust hole 224, the air in the enclosed space formed by the detection box 311 and the L-shaped slide 321 is extracted through the air supply pipe 217 and the exhaust hole 224, and the environment in which the detection object 323 is located is vacuumed. At this time, the air supply pipe 221 and the exhaust pipe 222 continue to rotate. When the air supply pipe 221 is connected with the air supply hole 223, the detection gas is filled into the detection object 323 through the connecting plugs 312 and 324. At this time, the gas in the space formed by the detection box 311 and the L-shaped slide 321 can be detected, so that whether there is leakage of the detection gas can be detected, and then the detection of leakage of the detection object 323 can be realized.

[0052] During the process of the exhaust pipe 222 being connected to the exhaust hole 224 and switching to the L-shaped slide 321 to start separating the detection box 311, the detection box 311 and the L-shaped slide 321 are always in a combined closed state, so that if there is a leakage in the detection item 323 during the switching period, the gas in the detection item 323 can slowly leak out a sufficient amount, thereby making the leakage detection of the detection item 323 more perfect, and there will be no situation where the leakage of the detection gas is small due to the short detection time, which leads to no detection.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
