[0001] The utility model relates to the technical field of sample turnover boxes, in particular to a sample sterile turnover box. Background Art

[0002] During the production process of some products, due to their own characteristics, they need to be dustproof and sterilized. Generally, they are operated in a sterile room. The sterile room environment for sterile product production needs to be strictly controlled to ensure that all the requirements of sterile production are met. The production environment should be kept clean, disinfected regularly, and maintained at appropriate temperature and humidity. The production area should be isolated from the non-sterile area to prevent cross contamination.

[0003] In the production of sterile products, the transfer or transportation of samples to different environments is an essential link. Through effective sterile product turnover, the quality and safety of the product can be ensured, microbial contamination and cross-contamination can be prevented, and the health and safety of consumers can be guaranteed. Therefore, sterile product turnover occupies a very important position in the entire sterile production process and is one of the key links to ensure product quality and reliability. The container used for sample transportation should be cleaned and disinfected before each use, which can ensure that the container is sterile when used and prevent the introduction of contamination during the transportation process.

[0004] The existing method of transferring or transporting sterile products generally uses sealed boxes or tanks for containment and transfer. However, due to the need to ensure sealing, this method generally has a more complicated locking structure, and the closing and opening methods are more troublesome. In addition, the air flow will be driven at the moment of opening, sucking dust and bacteria outside the container into the inside, affecting the dust and bacteria prevention effect.

[0026] The utility model is provided with a locking structure, including: after the cover body 2 is closed on the box body 1, a locking groove 5 is opened at the corresponding edges of the cover body 2 and the box body 1, and the locking groove 5 includes an arc section 51 and a vertical section 52. A limit rod 17 is fixed on the outer shell of the cover body 2 just above the vertical section 52. The limit rod 17 has a T-shaped cross section, and the limit rod 17 is provided with a plate-shaped lock handle 4 rotatably connected thereto. The specific rotational connection method is that a limit groove 21 matching the limit rod 17 is opened on the inner side wall of the lock handle 4, and the limit rod 17 is located in the limit groove 21 and rotates. A slide groove 22 is opened on the inner side wall of the lock handle 4, and a slider 24 is provided in the slide groove 22. The slider 24 is connected to the inner wall of the slide groove 22 through a tension spring 23. The slider 24 is also connected to a lock pin 18 outside the lock handle 4. When the lock handle 4 rotates, the lock pin 18 is located in the lock groove 5 and moves.

[0027] After the cover 2 is closed on the box 1, the first locking pin block 11 and the second locking pin block 20 are respectively fixed on the inner wall of the cover 2 and the box 1 corresponding to the locking groove 5, and the first locking pin block 11 and the second locking pin block 20 are provided with grooves matching the shape of the locking groove 5. The locking pin can be placed in the grooves provided in the first locking pin block 11 and the second locking pin block 20 to move, playing the role of auxiliary limit.

[0029] Handles 3 are provided on the outer sides of both sides of the box body 1, and the handles 3 are foldable handles.

[0030] The method of using the utility model is as follows: open the cover body 2, at which time the lock handle 4 is in a horizontal state, place the sample in the sample slot 9, and then pull out the dustproof film 8 in the installation box body 7 to release it, so that it completely covers the shockproof sponge 6 to form a dust barrier for the sample, and the free end of the dustproof film 8 after being released is placed on the pressure strip base 14, and the metal pressure strip 12 is flipped downward to the free end surface of the dustproof film 8. Under the magnetic attraction of the magnetic block 13, the metal pressure strip 12 presses the free end of the dustproof film 8 to form a clamp, and the dustproof film 8 prevents dust or microorganisms from entering and contaminating the sample.

[0031] Close the cover body 2 and rotate the lock handle 4 clockwise. At this time, under the action of the tension spring 23, the lock pin 18 moves along the arc section 51 of the locking groove 5. When the lock pin 18 moves to the bottom, under the tension of the tension spring 23, the lock pin 18 enters the vertical section 52 to form a lock. Here the lock handle 4 is in a vertical state. When the cover body 2 needs to be opened, slide the slide button 19 downward to drive the lock pin 18 to move down and out of the vertical section 52. At this time, turn the lock handle 4 counterclockwise to a horizontal state. The lock handle 4 can serve as a handle for the cover body 2, which is convenient for opening, simplifies the locking structure, and realizes the rapid opening and closing of the turnover box.
