The upper cross bar 83 penetrates the box door 2 and is rotatable with the box door 2. After the screw rod 81 rotates, the threaded sleeve 82 moves along the vertical sliding groove 14 through threaded transmission, and the threaded sleeve 82 can drive the box door 2 to move through the upper cross bar 83.

[0031] In this embodiment, the transmission component 7 includes a support platform 71 fixedly connected to the top of the work box 1. A servo motor 72 is fixedly installed on the top of the support platform 71. The output shaft of the servo motor 72 penetrates the support platform 71 and is fixedly sleeved with a driving sprocket 73. The top ends of the two screw rods 81 are fixedly sleeved with driven sprockets 74. A chain 75 is arranged in a transmission manner between the driving sprocket 73 and the two driven sprockets 74. The servo motor 72 can drive the driving sprocket 73 to rotate, and the driving sprocket 73 drives the two driven sprockets 74 to drive the two screw rods 81 to rotate synchronously through the chain 75, realizing the rotation of the screw rod 81.

[0032] In this embodiment, upper sliding grooves 9 are formed on both the left and right sides of the inner wall of the working box 1. A plurality of sliders 31 are fixedly connected to both sides of the support plate 3, and the sliders 31 are respectively slidably engaged with the two upper sliding grooves 9. The rear-row sliders 31 on both sides of the support plate 3 can respectively penetrate through the two fork rods 6 and are slidably engaged with them.

[0033] In this embodiment, a lower cross bar 10 is inserted and rotatably engaged with the lower part of the box door 2. Lower sliding grooves 11 are formed on both the left and right sides of the inner wall of the working box 1. Sliding push blocks 12 are fixedly connected to both ends of the lower cross bar 10, and the sliding push blocks 12 are slidably connected with the two lower sliding grooves 11. The sliding push blocks 12 can slide along the lower sliding grooves 11 and push the fork rods 6; the lower cross bar 10 can drive the sliding push blocks 12 to slide along the lower sliding grooves 11. After the sliding push blocks 12 move a certain distance, they contact the fork rods 6, causing the fork rods 6 to rotate around the pivot pins 5.

[0034] In this embodiment, a plurality of stop rods 32 are fixedly connected to the rear of the top of the support plate 3. A through groove 33 is formed in the front side of the top of the support plate 3. A limit block 34 is slidably arranged in the through groove 33. A limit rod 35 is fixedly connected to the top of the limit block 34. A pull rod 36 is fixedly connected to the side of the limit block 34 facing the box door 2. One end of the pull rod 36 away from the limit block 34 penetrates through and extends to the front side of the support plate 3. A spring 37 sleeved on the outer side of the pull rod 36 is fixedly connected between the front side of the limit block 34 and the inner wall of the through groove 33; the limit block 34 can be pulled through the pull rod 36 to move the limit rod 35 and compress the spring 37. After placing a sample on the support plate 3, releasing the pull rod 36 can cause the limit block 34 to drive the limit rod 35 to reset through the spring 37. The limit rod 35 and the stop rods 32 fix the sample to prevent the sample on the support plate 3 from falling when the support plate 3 moves back and forth.

[0035] In this embodiment, the cross sections of the through groove 33 and the limit block 34 are both "convex" shaped, and the side of the limit rod 35 facing the stop rod 32 is inclined; the cooperation between the limit block 34 and the through groove 33 makes the movement stable, and it is more convenient to place the sample through the inclined section of the stop rod 32.

[0036] In this embodiment, a sealing ring 13 is embedded and installed on the front side of the inner wall of the working box 1. When the box door 2 is in a vertical state, the front side of the box door 2 closely adheres to the sealing ring 13; the sealing ring 13 plays a sealing role when the box door 2 closes the working box 1.

[0037] The usage method and working principle of this device: When this device is in use,

[0038] First, the servo motor 72 drives the driving sprocket 73 to rotate. The chain 75 synchronously drives the two driven sprockets 74 to drive the two screws 81 to rotate. Through screw transmission, the two screw sleeves 82 move downward synchronously and drive the box door 2 through the upper cross bar 83. When the box door 2 moves, since its upper end and the upper cross bar 83 and the lower cross bar 10 below can rotate relative to the box door 2, and the sliding push blocks 12 at both ends of the lower cross bar 10 move along the lower sliding groove 11, when the box door 2 moves, through the cooperation of the screw sleeves 82 at both ends of the upper cross bar 83 and the vertical sliding groove 14 and the cooperation of the sliding push blocks 12 at both ends of the lower cross bar 10 and the lower sliding groove 11, the box door 2 folds towards the lower bottom wall of the working box 1 when moving. After the box door 2 drives the sliding push block 12 to move a certain distance along the lower sliding groove 11, the sliding push block 12 can contact the fork rod 6 and rotate around the pivot pin 5. The fork rod 6 pushes the slider 31 to slide in the upper sliding groove to drive the support plate 3 to move forward and move out of the working box 1. When the support plate 3 moves, the compression spring 4 is stretched. After the support plate 3 moves out of the working box 1, a sample can be placed on it;

[0039] Subsequently, the servo motor 72 rotates in reverse to reset the box door 2. When the box door 2 is reset, the sliding push block 12 also follows to reset. After the sliding push block 12 is reset, it no longer acts on the fork rod 6. The compression spring 4 will pull the support plate 3 to reset and make the support plate 3 return to the working box 1 until the box door 2 is completely closed;

[0040] In summary, the picking and placing of the sample only need to control the forward and reverse rotation of the servo motor 72. When the box door 2 is opened, the support plate 3 can move out of the working box 1 for placing the sample. When the box door 2 is closed, the support plate 3 can move to the working box 1 for subsequent operations. This not only greatly facilitates the user's detection work on the epidemic disease, but also avoids the user having to put their arm into the interior of the working box 1 to work. It achieves that the user does not need to put their arm into the interior of the workbench to perform the detection, solves the deficiencies in the prior art, and makes the opening and closing of the box door 2 and the support plate 3 more intelligent and automated.

[0041] During the above process, the limiting block 34 can be pulled by the pull rod 36 to move the limiting rod 35 and compress the spring 37. After placing the sample on the support plate 3, releasing the pull rod 36 can make the limiting block 34 drive the limiting rod 35 to reset through the spring 37. The limiting rod 35 and the blocking rod 32 fix the sample to prevent the sample on the support plate 3 from falling when the support plate 3 moves back and forth.

[0042] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
