[0002] Chemical reagents are relative standard substances used in chemical research and component analysis. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. Chemical reagents are indispensable in the daily work of factories, schools, hospitals and research institutes. The storage of chemical reagents is an important piece of equipment in the laboratory, used to store and protect various chemicals. Application No.: CN202422284377.6 (Announcement No.: CN223113090U) discloses a chemical reagent storage device for a chemical laboratory, including a cabinet with a door. A top block and a base are fixedly installed in the center of the top inner wall and the bottom inner wall of the cabinet, respectively. A rotating column is inserted into the center of the bottom of the top block and the center of the top of the base. Two side openings are symmetrically opened on the side of the rotating column, and a threaded sleeve is also fitted on the rotating column. The aforementioned patent makes it inconvenient to lock the trays on which reagents are placed during storage. If rotation occurs during storage, it will cause the liquid inside the reagent tubes to shake, and in severe cases, it may cause the chemical reagents to spill out. Utility Model Content

[0003] The purpose of this invention is to provide a chemical reagent storage container for the laboratory, so as to solve the technical problem mentioned in the background art that it is inconvenient to lock the rack on which the reagent is placed during storage, and that the chemical reagent will spill out if it rotates during storage.

[0004] This utility model is implemented as follows: This utility model provides a chemical reagent storage container for a laboratory, which has a cabinet body with a cabinet door and a base fixedly installed in the center of the bottom wall of the cabinet body. A tray is rotatably connected inside the cabinet body, and a screw is fixedly installed in the bottom wall of the tray. The screw is threadedly connected to a threaded sleeve, and the threaded sleeve is rotatably connected to the base. The upper end of the threaded sleeve is fixedly installed with multiple sets of positioning components. Each set of positioning components includes two positioning plates. A vertically movable positioning post is movably connected within the two positioning plates of the set. A locking component is provided below the positioning plate to position the positioning post inserted into the positioning plate.

[0005] Based on the above technical solution, the laboratory chemical reagent storage container of this utility model can be further improved as follows: Furthermore, the locking assembly includes a sliding sleeve fixedly installed on the bottom wall of the cabinet body, the positioning post being slidably connected inside the sliding sleeve, a positioning seat in the shape of a "⊂" being fixedly installed at the lower end of the right side wall of the positioning post, a vertical through groove being provided on the right side wall of the sliding sleeve, and the positioning seat being slidably connected inside the through groove.

[0006] Furthermore, two limiting plates are fixedly installed on the front wall of the sliding sleeve, and a horizontally arranged sliding rod is slidably connected inside the limiting plates. A spring is sleeved on the outer circumference of the sliding rod, and the spring is located between the two limiting plates. A positioning rod is fixedly installed on the right wall of the sliding rod, and the positioning rod is movably connected to the positioning seat.

[0007] Furthermore, a horizontally arranged guide plate is fixedly installed on the circular hole of the limiting plate, and a horizontally through guide groove is opened on the sliding rod, and the guide plates are all slidably connected in the guide groove.

[0008] Furthermore, a support shaft is fixedly installed on the top wall of the tray, and a bearing with a diamond-shaped seat is fixedly installed on the outer circumferential surface of the top end of the support shaft. Two pins are inserted into the seat hole of the bearing with diamond-shaped seat, and nuts are provided on the top and bottom walls of the bearing with diamond-shaped seat and screwed onto the pins.

[0009] Compared with the prior art, the beneficial effects of the laboratory chemical reagent storage container provided by this utility model are: By setting a locking component, the tray can be prevented from rotating, thus avoiding the movement of the cabinet body during the storage of reagent tubes, which would cause the tray to rotate and the liquid inside the reagent tubes to shake. By setting symmetrical nuts at the top and bottom to limit the height of the bearing with diamond-shaped seat under the action of the pin, the tray can be prevented from moving up and down. At this time, both the tray and the screw can rotate in place, and the screw cannot spiral up, further avoiding improper operation that would cause the screw to be twisted relative to the threaded sleeve when storing reagent tubes. By setting guide plates and guide grooves, the sliding rod can be prevented from rotating, thus preventing the positioning rod from rotating and allowing it to move only laterally.

[0017] Example 1 like Figure 1-4 As shown, this utility model provides a chemical reagent storage container for a laboratory, which has a cabinet body 1, a cabinet door on the cabinet body 1, and a base 11 fixedly installed in the center of the bottom wall of the cabinet body 1. A tray 2 is rotatably connected inside the cabinet body 1, and a screw 21 is fixedly installed in the bottom wall of the tray 2. The screw 21 is threadedly connected in a threaded sleeve 22, and the threaded sleeve 22 is rotatably connected in the base 11. Multiple positioning components are fixedly installed on the upper end of the threaded sleeve 22. Each positioning component includes two positioning plates 31. A vertically movable positioning post 32 is movably connected within the two positioning plates 31. A locking component is provided below the positioning plate 31 to position the positioning post 32 inserted into the positioning plate 31.

[0018] Optionally, in the above technical solution, the locking component includes a sliding sleeve 34 fixedly installed on the bottom wall of the cabinet body 1, a positioning post 32 slidably connected in the sliding sleeve 34, a positioning seat 33 in the shape of "⊂" fixedly installed at the lower end of the right side wall of the positioning post 32, a vertical through groove 35 is opened on the right side wall of the sliding sleeve 34, and the positioning seat 33 is slidably connected in the through groove 35.

[0019] Optionally, in the above technical solution, two limiting plates 41 are fixedly installed on the front wall of the sliding sleeve 34. A horizontally arranged sliding rod 42 is slidably connected inside the limiting plates 41. A spring 43 is sleeved on the outer circumferential surface of the sliding rod 42. The spring 43 is located between the two limiting plates 41. A positioning rod 44 is fixedly installed on the right wall of the sliding rod 42. The positioning rod 44 is movably connected to the positioning seat 33.

[0020] Optionally, in the above technical solution, a horizontally arranged guide plate 45 is fixedly installed on the circular hole of the limiting plate 41, and a horizontally through guide groove 46 is opened on the sliding rod 42, and the guide plate 45 is slidably connected in the guide groove 46.

[0021] Optionally, in the above technical solution, a support shaft 12 is fixedly installed on the top wall of the tray 2, and a bearing 13 with a diamond-shaped seat is fixedly installed on the outer circumferential surface of the top end of the support shaft 12. Two pins 14 are inserted into the seat hole of the bearing 13 with a diamond-shaped seat, and nuts 15 screwed onto the pins 14 are provided on the top and bottom walls of the bearing 13 with a diamond-shaped seat.

[0022] The movable connection is a plug-in connection. Preferably, the positioning plate 31 and the positioning post 32 are fitted with a clearance, and the positioning seat 33 and the positioning rod 44 are fitted with a clearance. The positioning post 32 is hollow to reduce its own weight. When the tray 2 is rotated, the screw 21 rotates in place, the threaded sleeve 22 rotates in place within the base 11, and the support shaft 12 rotates in place within the bearing 13 with a rhomboid seat.

[0023] Furthermore, the right end of the spring 43 is fixedly installed on the right side limiting plate 41, and the left end of the spring 43 is fixedly installed on the circumferential surface of the sliding rod 42. The force required to move the sliding rod 42 to the right and compress the spring 43 is needed to move the positioning rod 44 to the right and disengage it from the positioning seat 33.

[0024] Working principle: When using, open the cabinet door of the storage cabinet body 1 and place the reagent tubes to be stored into the front slot 20. (If the front slot 20 is occupied, rotate the tray 2 to move the empty slot 20 to the front. If there are multiple reagent tubes to be stored, rotate the tray 2 multiple times to move the empty slot 20 to the front. The purpose of placing them from the front is to avoid having to go around other reagent tubes during placement, causing collisions, or making the operation inconvenient when placing them at the back.) After the reagent tube is placed, the circumferential rotation of the threaded sleeve 22 is locked by the locking assembly. Combined with the axial limiting structure locked by the top pin 14 and the upper and lower nuts 15, the screw 21 cannot move axially or rotate relative to the threaded sleeve 22, thus completely locking the tray 2. This prevents the movement of the placement cabinet body 1 from causing the threaded sleeve 22 or the tray 2 to rotate unexpectedly, which could cause the liquid inside the reagent tube to shake or even spill out. The locking assembly is used as follows: With the two positioning plates 31 of a set of positioning assemblies in front, pull the sliding rod 42 to the right, causing the positioning rod 44 to move to the right simultaneously, compressing the spring 43, so that the positioning rod 44 moves to the right side of the positioning seat 33; pull the positioning pin 32 upward to insert it between the two positioning plates 31, and when the groove of the positioning seat 33 corresponds to the height of the positioning rod 44, release the sliding rod 42, and the spring 43 rebounds to push the sliding rod 42 to the left, causing the positioning rod 44 to be inserted into the groove of the "⊂" shaped positioning seat 33, locking the vertical position of the positioning pin 32 (when not locked, the bottom wall of the positioning pin 32 is located on the inner bottom wall of the cabinet body 1, and the top wall of the positioning pin 32 is located below the bottom wall of the positioning plate 31). The height of the tray 2 can be adjusted according to the height of the stored reagent tubes. During adjustment, the threaded sleeve 22 is locked. At this time, press the threaded sleeve 22 to further stabilize it, and rotate the screw 21 to rotate it relative to the threaded sleeve 22, thereby driving the tray 2 to move up and down. During the movement of tray 2, the support shaft 12 drives the diamond-shaped bearing 13 to move up and down. After moving to the appropriate position (before this, the nut 15 cannot be attached to the diamond-shaped bearing 13), the nuts 15 at both ends of the diamond-shaped bearing 13 are screwed onto the top and bottom walls of the diamond-shaped bearing 13 through the pin 14, so that the diamond-shaped bearing 13 cannot move up and down. Similarly, the height of the support shaft 12 and tray 2 is locked, so the screw 21 cannot move up and down along the tray 2. Therefore, the screw 21 cannot rotate relative to the tray 2, further preventing the tray 2 from rotating when storing test tubes.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
