A bottle rack sliding column 27 is installed on the side of the bottle rack for controlling the opening and closing angle and opening and closing timing of the bottle rack 26. The lower section of the bottle rack 26 is provided with an axial hole and a torsion spring groove, and the side and upper observation surface of the bottle rack 26 are provided with a large number of hollows to facilitate the user to observe the remaining amount of medicine.

[0031] Working principle and process of this utility model:

[0032] The sample box 1 has a graded sliding structure among the lower cover 2, the upper cover 3 and the bottle rack 26, so that when unfolding, the upper cover 3 first rises 35 degrees under the action of the torsion spring, and then because the lower end of the bottle rack sliding groove 4 of the upper cover 3 touches the bottle rack sliding column 27 on the side of the bottle rack 26, the bottle rack 26 is driven by the upper cover 3 to rise 35 degrees to complete the second stage of unfolding. The upper cover 3 has a bottle rack sliding groove 4 for limiting the movable angle of the bottle rack 26, and the groove is combined with the bottle rack sliding column 27 on the side of the bottle rack 26. The front end of the upper cover 3 has a medicine bottle giving way groove 6 to prevent the upper cover 3 from interfering with the movement of the medicine bottle when opening. There is an upper cover sliding groove for limiting the active angle of the upper cover 3, and the groove is combined with the bottle rack sliding column 27 on the side of the upper cover 3. The rear end of the lower cover 2 is provided with a mounting shaft hole for installing the upper cover 3 and the bottle rack 26 and a ramp for limiting the expansion angle of the bottle rack 26. At the same time, a mounting hole for the torsion spring is reserved. One end of the torsion spring is inserted into the hole, and the other end is installed in the upper cover torsion spring groove 5, thereby causing a driving force for the upper cover 3 to expand. The front end of the lower cover 2 is provided with a lock tongue limiting column 17, a lock tongue shaft hole 18 and a lock tongue spring groove 19 for limiting the lock tongue, and a lock tongue finger groove 20 space is reserved for pressing the lock tongue down. At the same time, the lock tongue finger groove 20 is provided. The slope of the groove 20 also serves as an angle limit for the lock tongue when unlocking. Therefore, when the upper cover 3 is closed, the lower edge of the upper cover 3 will hit the slope, causing the lock tongue to tilt backward. Then, when the upper cover 3 moves into place, the lock tongue falls back into the lock tongue groove 10 of the upper cover to complete the automatic locking. The user can open the upper cover 3 by pressing the lock tongue and pressing the anti-slip groove 23. Based on the limitations of the bottle rack 26, the upper cover 3, the lock tongue, etc. in the sample box 1, the expansion angle of the box is limited. At the same time, due to the blocking effect of the medicine bottle card platform 25 on the bottle rack 26 on the lower edge of the bottle cap, the medicine bottle will not slide out of the bottle rack 26 at any angle. At the same time, When putting the medicine bottle in, the blocking effect of the medicine bottle holder 25 on the lower edge of the medicine bottle cap will cause the medicine bottle to slightly collide with the base of the bottle rack 26 due to the sudden change in resistance caused by the medicine bottle holder 25 entering the groove at the lower edge of the medicine bottle cap when it is finally pushed to the bottom, so that the user can feel that the medicine bottle is in place through touch and sound. A bottle rack sliding column 27 is installed on the side of the bottle rack for controlling the opening and closing angle and opening and closing timing of the bottle rack 26. The lower section of the bottle rack 26 is provided with an axial hole and a torsion spring groove, and the side and upper observation surface of the bottle rack 26 are provided with a large number of hollows to facilitate the user to observe the remaining amount of medicine.
