The test tube rack is equipped with a corresponding number of small wooden columns and small holes. The test tube with small holes can be placed upright for standby or to continue observing the reaction. The test tube with columns can be placed upside down for drying.

[0003] After searching, a Chinese patent with publication number CN208482502U discloses a test tube rack, including a cover, a base and a placement rack for placing test tubes, the placement rack matches the base, a movable handle is arranged on the top of the cover, an annular flange is arranged on the other side of the cover relative to the movable handle, a base flange matching the annular flange is arranged on the base, a flange buckle for clamping the cover is arranged on the base, and the flange buckle is movably connected to the base. The utility model provides a test tube rack to solve the problems existing in the prior art that the test tube rack cannot distinguish marks, the patient's blood samples are easily confused and missed, and the transfer and transportation are inconvenient.

[0004] Although the above scheme can solve the problems in the prior art that the test tube rack cannot distinguish the marks, the patient's blood samples are easily confused and missed, and the transfer and transportation are inconvenient, the test tube rack device in the above patent is difficult to be adjusted according to the aperture size of the test tube, and it is difficult to mix and place tubes of various apertures, save consumables, and facilitate operation; for this reason, we provide a test tube rack for the laboratory with an adjustable aperture and a buffer structure to solve the above problems.

[0025] See also Figure 2 and Figure 4One end of the upper surface of the first base 201 is connected to the lifting mechanism 1, and the lifting mechanism 1 includes a supporting slide column 106. The inner sliding groove of the supporting slide column 106 is slidably connected to one side of the first sliding block 104. The first sliding block 104 is set to a rectangle. A first electric hydraulic rod 105 is fixedly arranged in the middle of the lower surface of the first sliding block 104. The rectangular width value of the first sliding block 104 is greater than the width value of the first electric hydraulic rod 105. Under the push of the first electric hydraulic rod 105, the first sliding block 104 can be lifted up and down. When it is necessary to take out the test tube, the upper lifting cover plate 103 is lifted and lowered by the first electric hydraulic rod 105 for convenient access. One end of the first sliding block 104 is fixedly connected to one end of the upper lifting cover plate 103. The upper lifting cover plate 103 is set to a rectangle. A display control screen 1 is fixedly arranged in the middle of the upper surface of the upper lifting cover plate 103. 02, the rectangular width value of the upper lifting cover 103 is greater than the width value of the display control screen 102. Through the display of the display control screen 102, the storage position of the test tube can be easily checked, which is convenient for medical staff to quickly take it. One side of the upper lifting cover 103 is fixedly connected to one end of the ventilation and exhaust pump 101. The residual gas in the test tube is discharged to the outside through the ventilation and exhaust pump 101. When the gas flows out, the ventilation and exhaust pump 101 filters the gas to produce toxic gas in the gas in the test tube. The middle part of one end of the outer cylindrical surface of the first adjusting shaft 204 is transmission-connected with one end of the first belt 207, so that the test tube can be buffered according to the storage position of the test tube to prevent it from playing a buffering role when the test tube is pressed down. When the first adjusting shaft 204 rotates, it drives the first belt 207 and the second belt 208, which can facilitate the rotation of the second adjusting rotating block 203.

[0026] See also Figure 5The other end of the first belt 207 is transmission connected with the outer circular surface of one end of the second adjusting shaft 206. The second adjusting shaft 206 is set to be circular. The middle part of one end of the second adjusting shaft 206 is rotatably connected with a second fixed block 209. The middle part of one end of the second adjusting shaft 206 is rotatably set with a second fixed block 209. The width value of one side of the second adjusting shaft 206 is less than the width value of the second fixed block 209. It is fixed by the second fixed block 209 to prevent the second adjusting shaft 206 from shaking during rotation and the second adjusting shaft 206 from suddenly not working. The outer circular surface in the middle of one end of the second adjusting shaft 206 is transmission connected with one end of the second belt 208. The second adjusting shaft 206 is driven to rotate by the first belt 207, and the second adjusting shaft 206 is driven to rotate while the second adjusting shaft 206 rotates. The belt 208 rotates synchronously, the inner sliding groove of the sliding groove 301 is slidably connected to one end of the second sliding block 304, the other end of the third sliding block 303 is fixedly connected to one end of the first test tube fixing frame 302, one side of the first test tube fixing frame 302 is fixedly connected to one end of the second double-piston hydraulic cylinder 306, the other end of the second double-piston hydraulic cylinder 306 is fixedly connected to one side of the second test tube fixing frame 305, and one end of the second test tube fixing frame 305 is fixedly connected to one end of the second sliding block 304. When the test tube is placed, the second double-piston hydraulic cylinder 306 pushes the first test tube fixing frame 302 to slide back and forth, so that it can be adjusted according to the aperture size of the test tube, and the second sliding block 304 slides inside the sliding groove of the sliding groove 301 when the first test tube fixing frame 302 slides.

[0027] Working principle: The first sliding block 104 is pushed up and down by the first electric hydraulic rod 105. When the first sliding block 104 is lifted up and down, the upper lifting cover plate 103 is driven to lift up and down. Through the display of the display control screen 102, the liquid stored in the test tube can be viewed, and the liquid composition in the test tube can also be checked. When the liquid in the test tube is ventilated outward, the air in the test tube can be ventilated through the ventilation pump 101. The second adjusting rotating block 203 can be rotated by rotating the first adjusting shaft 204. The second adjusting rotating block 203 can buffer the bottom of the test tube to prevent the test tube from being squeezed. When the test tube is broken, the first adjusting shaft 204 rotates but the first belt 207 and the second belt 208 are driven to rotate synchronously. The first base 201 supports the placement rack 202, and the placement rack 202 can fix the test tube to place the test tube. The first test tube fixing rack 302 and the second test tube fixing rack 305 are pushed by the second double-piston hydraulic cylinder 306. The test tube can be adjusted according to the size of the test tube aperture, which is convenient for storing test tubes with different apertures, which is beneficial to saving material waste. The structure is simple, and it is automatically adjusted according to the test tube aperture size, and the stability of the test tube is effectively controlled.
