DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

Two connecting rods 3 are arranged on the top of the fixed base 2, and the two connecting rods 3 are provided in two groups, and they are both located on the left and right sides of the fixed base 2, one end of the left connecting rod 3 passes through the sample slot and is fixedly installed with the first fixed block 4, and one end of the right connecting rod 3 passes through the sample slot and is fixedly installed with the second fixed block 5, the fixed bases 2 are connected by the connecting block 6, the first fixed blocks 4 are connected by the first movable block 7, the second fixed blocks 5 are connected by the second movable block 8, a limiting structure is arranged inside the first movable block 7 and on the top of the connecting block 6, and a sealing cover 9 is hinged on one side of the second fixed block 5.

After the temperature and time conditions are controlled by the detection device 1, it is convenient to carry out the detection. After the detection is completed, the first fixed block 4 and the second fixed block 5 are moved upwards, so that the second fixed block 9 and the second fixed block 8 are moved upwards. Block 5 drives the first moving block 7 and the second moving block 8 to move upward, and through the connection between the connecting rod 3 and the connecting block 6, it drives the fixed base 2 to move upward at the same time, so that the sample tube 23 inside the fixed base 2 moves upward together. When multiple fixed bases 2 move out of the sample slot, the multiple sample tubes 23 inside the fixed base 2 can be moved out of the sample slot together. When the sample tube 23 moves, the sealing of the sealing cover 9 can prevent the sample tube 23 from being collided or accidentally slipping when it is taken out, which can easily splash the sample liquid inside the sample tube 23 and contaminate the detection equipment 1, affecting the re-detection of the sample liquid on the inner wall of the sample tube 23, thereby facilitating improving the efficiency of sample detection.

[0025] like Figures 7 and 8 As shown, the limiting structure includes a telescopic rod 17, a moving rod 18, a first magnetic block 19, a second magnetic block 20, a limiting block 21, and a connecting spring; A moving rod 18 is fixedly installed on the top of the telescopic rod 17, and a first round convex is fixedly installed on the top of the moving rod 18. A first magnetic block 19 is fixedly installed on one end of the moving rod 18, and a second magnetic block 20 is fixedly installed inside the fixed groove. The first magnetic block 19 is magnetically connected to the second magnetic block 20. Both sides of the limiting block 21 are slidably connected to the inner wall of the first moving block 7. One end of the connecting spring is fixedly installed on the limiting block 21, and the other end thereof is fixedly installed on the inner wall of the first moving block 7. One end of the limiting block 21 is plugged into the limiting opening 15. The bottom of the telescopic rod 17 is fixedly installed on the top of the connecting block 6. The telescopic rod 17 and the moving rod 18 are arranged corresponding to the movable opening. The top of the moving rod 18 is a first round convex, and the side of the limiting block 21 close to the movable opening is an inclined surface, and the limiting block 21 is arranged corresponding to the first movable opening.

[0026] After the first fixed block 4 drives the first moving block 7 and the second fixed block 5 drives the second fixed block 5 to move to both sides of the sample tube 23, the first moving block 7 fits with one side of the second moving block 8, and the first moving block 7 moves to the bottom of the telescopic rod 17, so that the movable opening at the bottom of the first moving block 7 corresponds to the telescopic rod 17, and the second magnetic block 20 in the fixed groove is magnetically connected with the first magnetic block 19, so that the telescopic rod 17 is extended to drive the moving rod 18 to move upward, and the moving rod 18 moves to the inside of the first moving block 7 through the movable opening, and the first round protrusion on the top of the moving rod 18 moves along the inclined surface of the limiting block 21, squeezing the limiting block 21, so that the connecting spring stretches, so that the limiting block 21 moves from the first moving opening to the limiting opening 15 of the second moving block 8, so that the limiting block 21 is plugged with the limiting opening 15, limiting the first moving block 7 and the second moving block 8, improving the stability of the first moving block 7 and the second moving block 8, the first fixed block 4 and the second fixed block 5 in limiting the sample tube 23, thereby facilitating the simultaneous removal of multiple sample tubes 23 after the detection is completed.

[0027] like Fig. 9 As shown, a support structure 22 is provided inside the fixed base 2 and between the connecting rods 3; the support structure 22 includes a movable plate 221, a movable rod 222, a movable block 223, a fixed spring 224, and a support plate 225. The movable rod 222 is fixedly installed on one side of the movable plate 221, and a movable block 223 is provided on one side of the movable rod 222. A fixed spring 224 is fixedly installed in the middle of one side of the movable block 223, one end of the fixed spring 224 is fixedly installed on the inner wall of the slide groove, and a support plate 225 is fixedly installed on the other side of the movable block 223. One end of the movable plate 221 is fixedly installed on the bottom end of the connecting rod 3, both sides of the movable plate 221 are slidably connected to the slide groove, the bottom of the movable block 223 is slidably connected to the inner wall of the bottom of the slide groove, and second movable openings are opened on both sides of the inner wall of the fixed base 2, the support plate 225 is located at the second movable opening, and its bottom is slidably connected to the inner wall of the fixed base 2.

[0028] When the connecting rod 3 drives the movable plate 221 to move closer to each other along the inside of the slide groove, the movable plate 221 drives the movable rod 222 to move in the direction of the movable block 223, so that the movable block 223 is squeezed and the fixed spring 224 is stretched, so that the movable block 223 drives the support plate 225 to move from the second movable port to the inside of the fixed base 2, so that the support plate 225 moves to both sides of the sample tube 23, and the bottom end of the sample tube 23 is supported and fixed by the support plate 225 to prevent the sample tube 23 from shaking in the fixed base 2 when the fixed base 2 drives the sample tube 23 to move upward, thereby affecting the movement of the sample tube 23, causing the sample liquid to shake, and affecting the efficiency of replacing multiple sample tubes 23.

[0029] like Fig. 9 As shown, the movable rod 222 is provided with a second convexity at one end away from the connecting rod 3, and the movable block 223 is provided with an inclined surface on the side close to the second convexity. The movable plate 221, the movable rod 222, the movable block 223, the fixed spring 224 and the support plate 225 are all symmetrically arranged around the center of the fixed base 2.

[0030] When the connecting plate drives the movable rod 222 to move in the direction of the movable block 223, the second round protrusion on one side of the movable rod 222 moves along the inclined surface on one side of the movable block 223 to squeeze the movable block 223, so that the movable block 223 drives the support plate 225 to move. Through the symmetrically arranged movable plate, movable rod 222, movable block 223, fixed spring 224 and support plate 225, both sides of the sample tube 23 are supported, thereby improving the stability of the movement of the sample tube 23.

[0031] Working principle: When in use, the processed sample is sampled through the sampler and put into the sample tube 23, and then the sample tube 23 is placed in the sample slot of the detection device 1 and placed in the fixed base 2, the first fixed block 4 is moved to drive the first moving block 7, and the second fixed block 5 drives the second moving block 8 to move closer to each other, and the connecting rod 3 moves closer to each other along the slide groove, so that the first moving block 7 fits one side of the second moving block 8, and the first moving block 7 is moved to the top of the telescopic rod 17, and the movable port is set corresponding to the telescopic rod 17, and the second magnetic block 20 in the fixed slot is magnetically connected to the first magnetic block 19, so that the telescopic rod 17 is extended to drive the moving rod 18 to move upward, and the moving rod 18 moves to the inside of the first moving block 7 through the movable port, and the first round convex on the top of the moving rod 18 moves along the inclined surface of the limiting block 21, squeezing the limiting block 21 to drive the connecting spring to stretch, so that the limiting block 21 moves from the first moving port to the second moving block 8 The limiting opening 15 is formed by the limiting block 21 and the limiting opening 15, and the first moving block 7 and the second moving block 8 are limited. Then, the two sides of the top of the sample tube 23 are limited by the first fixed block 4 and the second fixed block 5. The sealing cover 9 is rotated to block and seal the top of the sample tube 23, so that the sample tube 23 remains sealed. The detection device 1 controls the temperature and time conditions and then performs the detection. When the detection is completed, the electric push rod 12 is started to drive the push plate 13 to move upward, so that the push plate 13 pushes the fixed base 2 to move upward, and then the pull block 16 is pulled to drive the first moving block 7 and the second moving block 8 to move upward, so that the first fixed block 4 and the second fixed block 5 move. Through the connection between the connecting rod 3 and the connecting block 6, the fixed base 2 is driven to move upward at the same time, so that the sample tube 23 inside the fixed base 2 is moved upward together, so that the multiple sample tubes 23 inside the fixed base 2 can be moved out of the sample slot together, which is convenient for improving the efficiency of sample detection.

[0032] When the connecting rod 3 drives the movable plate 221 to move closer to each other along the inside of the slide groove, the movable plate 221 drives the movable rod 222 to move in the direction of the movable block 223, so that the second convex part on the side of the movable block 223 moves along the inclined surface of the movable block 223, so that the movable block 223 is squeezed and the fixed spring 224 is stretched, so that the movable block 223 drives the support plate 225 to move from the second movable port to the inside of the fixed base 2, so that the support plate 225 moves to both sides of the sample tube 23, and the bottom end of the sample tube 23 is supported and fixed by the support plate 225 to prevent the sample tube 23 from shaking in the fixed base 2 when the fixed base 2 drives the sample tube 23 to move upward, thereby affecting the movement of the sample tube 23, causing the sample liquid to shake, and affecting the efficiency of replacing multiple sample tubes 23.
