[0043] The guide rail 5231 is disposed at the upper end of the bottom plate 521, and the rack 5232 is disposed on the guide rail 5231, so that when the output end of the driving member 522 rotates, the rack 5232 moves on the guide rail 5231, driving the slides and the sliding hooks 5234 on both sides to move relatively close to or away from each other, and the sliding hooks 5234 move close to or away from each other to clamp or release the barrel cover 32, thereby unlocking the barrel cover 32. The shape of the sliding hook 5234 can cooperate with the barrel cover 32, thereby facilitating the clamping or releasing of the barrel cover 32.

[0044] The unlocking device of the sample collecting barrel 3 of the embodiment of the present invention is provided with a guide rail 5231 and a rack 5232. The rack 5232 is used to engage with the output end of the driving member 522. The output end of the driving member 522 rotates to drive the rack 5232 to move back and forth on the guide rail 5231, thereby moving the sliding rod 5233 and the sliding hook 5234 on both sides closer to or away from each other, so as to facilitate clamping or releasing the barrel cover 32. There is no need to manually pick up or put down the barrel cover 32, thereby avoiding cross-contamination of samples caused by manual operation.

[0045] Furthermore, the sliding hook 5234 includes a connecting plate 52341 and a bending plate 52342, the connecting plate 52341 is connected to the bending plate 52342, the sample collecting barrel 3 includes a barrel body 31 and a barrel cover 32, the barrel cover 32 is detachably placed on the top of the barrel body 31, and the barrel cover 32 is provided with a bending portion 321 corresponding to the bending plate 52342.

[0046] The connecting plate 52341 extends in the up-down direction, and the bending plate 52342 extends in the horizontal direction. The bending plate 52342 may be an arc-shaped plate, and the openings of the two arc-shaped plates are opposite to each other so as to clamp the barrel cover 32 when they are close to each other.

[0047] At the same time, a bending portion 321 corresponding to the bending plate 52342 is provided on the barrel cover 32, so that when the bending plate 52342 moves with the connecting plate 52341, the bending portion 321 is clamped or released, thereby clamping or releasing the barrel cover 32.

[0048] In some embodiments, a limit block and a guide block are also provided on the top of the bottom plate 521. One end of the slide bar 5233 passes through the guide block and is connected to the slide hook 5234.

[0049] A limiting portion corresponding to the limiting block is disposed at the bottom of the rack 5232 to prevent the unlocking claw 523 from being separated from the bottom plate 521 .

[0050] A raised limiting portion is provided at the bottom of the rack 5232 , and a limiting block is provided on the bottom plate 521 , thereby preventing the rack 5232 from separating from the bottom plate 521 due to inertia when the rack 5232 moves, thereby improving the stability of the rack 5232 in use.

[0051] In some embodiments, the unlocking component 52 further includes a magnetic component 7 and a micro switch 8 disposed at the bottom of the bottom plate 521 , and a monitoring end of the micro switch 8 faces away from the bottom plate 521 .

[0052] Specifically, Figures 1 to 6As shown, when clamping the barrel cover 32, the magnetic attraction component 7 is activated to generate magnetic force to magnetically adsorb the barrel cover 32, and the micro switch 8 is set at the bottom of the bottom plate 521. The monitoring end of the micro switch 8 is facing away from the bottom plate 521. The micro switch 8 is used to determine whether the unlocking claw 523 grasps the barrel cover 32 to avoid unlocking failure and improve the stability and safety of unlocking. At the same time, the magnetic force generated by the magnetic attraction component 7 can unlock the barrel cover 32 alone when the unlocking claw 523 fails. Thereby improving the stability of unlocking.

[0053] In some embodiments, the unlocking device of the sample collecting barrel 3 also includes a first induction switch 9 and a second induction switch 10 arranged on the frame 1, and the position of the first induction switch 9 on the frame 1 corresponds to the position of the input end of the conveying component 2 on the frame 1, and the position of the second induction switch 10 on the frame 1 corresponds to the position of the output end of the conveying component 2 on the frame 1.

[0054] Specifically, Figures 1 to 6 As shown, the first induction switch 9 is arranged at the upper frame 1 at the left end of the conveying assembly 2, and the second induction switch 10 is arranged at the upper frame 1 at the right end of the conveying assembly 2. When the sample collecting barrel 3 is input to the left end of the conveying assembly 2, i.e., the input end, the first induction switch 9 detects the input of the sample collecting barrel 3, and then the conveying assembly 2 is started, i.e., the conveying component 21 and the barrel pushing assembly are started, and the sample collecting barrel 3 is conveyed to the output end of the conveying assembly 2, and then the second micro switch 8 detects that the sample collecting barrel 3 is located at the output end of the conveying assembly 2. At this time, the unlocking assembly 5 is started to unlock the sample collecting barrel 3 for subsequent sampling.

[0055] In some embodiments, the unlocking device of the sample collecting barrel 3 further includes a controller and a wireless transmission module, and the controller is connected to the unlocking component 5, the horizontal moving component 4, the first induction switch 9 and the second induction switch 10 respectively. For example, the controller is connected to the unlocking component 5 and the second induction switch 10, and then when the second induction switch 10 detects that the sample collecting barrel 3 is located at the output end of the conveying component 2, the unlocking component 5 is started to unlock the sample collecting barrel 3, and the controller is also connected to the micro switch 8 to determine whether the unlocking claw 523 unlocks the sample collecting barrel 3. The controller controls the unlocking component 5 to move after unlocking to move the barrel cover 32 to the cover support frame 6. The controller receives data from the first induction switch 9 to determine whether to start the conveying component 2. For example, when the sample collecting barrel 3 is conveyed to the input end of the conveying component 2, the first induction switch 9 detects the input of the sample collecting barrel 3, and the controller controls the conveying component 2 to start, and moves the sample collecting barrel 3 to the output end of the conveying component 2 for unlocking. The controller is connected to the wireless transmission module, and the controller can be wirelessly connected to the unlocking component 5, the horizontal moving component 4, the first induction switch 9 and the second induction switch 10 respectively through the wireless transmission module.
