Description

Technical Field

[0001] This utility model belongs to the technical field of pharmaceutical testing chambers, specifically a pharmaceutical strong light irradiation testing chamber. Background Technology

[0002] Pharmaceutical strong light irradiation test chambers are mainly used to simulate strong light environments and evaluate the stability and degradation characteristics of pharmaceuticals under light conditions. By precisely controlling the light intensity, temperature (10-65℃), and humidity, they simulate the strong light conditions that pharmaceuticals may be exposed to during storage, transportation, or use, and evaluate their chemical stability, degradation characteristics, and changes in physical properties to ensure quality control during storage and transportation. However, in the use of common pharmaceutical strong light irradiation test chambers, the strong light lamps inside the chamber are fixedly installed, and the irradiation distance between the lamps and the pharmaceuticals cannot be changed when the pharmaceuticals are irradiated with strong light. Different distances of strong light irradiation produce different effects on the pharmaceuticals, which can lead to inaccurate experimental data. Therefore, this application proposes a pharmaceutical strong light irradiation test chamber. Utility Model Content

[0004] Preferably, each of the four corners of the lifting plate has a through hole that runs vertically through it, and the four through holes on the lifting plate are respectively movably fitted onto four positioning posts. Both sides of the lifting plate are fixedly installed with a drive mechanism.

[0005] Preferably, the drive mechanism includes a fixed block, a motor, and a screw. The fixed block is fixedly installed at the center of both sides of the lifting plate. A through screw hole is provided on the top of the fixed block. The motor is fixedly installed on the top of the main body. The screw is threaded into the screw hole on the fixed block. The top end of the screw is fixedly connected to the output end of the motor, and the bottom end of the screw is rotatably connected to the shelf.

[0006] Preferably, an opening is provided at the center of both ends of the top of the shelf, and a bearing is fixedly installed in each of the two openings. The bottom ends of the screws in the two transmission mechanisms are respectively fixedly connected to the inner ring walls of the two bearings.

[0007] Preferably, the bottom of the storage slot has a slot through which the storage plate passes. Multiple horizontal fixed shafts are fixedly installed in the slot, and a roller is rotatably sleeved on each fixed shaft. The top of each roller extends out of the slot and abuts against the bottom of the storage tray.

[0008] Preferably, the opening of the test chamber is provided with a flip-up door, and two hinges are fixedly installed between one end of the door and the outer wall of the main body.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] By operating the motor, the screw and the screw holes on the fixed blocks at both ends of the lifting plate can be driven to rotate. In this way, the two motors on the main body can be operated at the same time, which can drive the lifting plate to move up and down along the direction of the positioning column in the test chamber. This can change the distance between the multiple high-intensity lamps at the bottom of the lifting plate and the placement tray, so that the test medicine in the placement tray can be irradiated with high-intensity light at different distances. In this way, the effect of irradiating the medicine at different distances can be tested. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figure 1-5 The present invention includes a main body 1, with a test chamber 2 on the front. Vertical positioning posts 3 are fixedly installed at the four corners inside the test chamber 2. A placement plate 4 is provided at the bottom inside the test chamber 2, and the four corners of the placement plate 4 are respectively fixedly sleeved on the four positioning posts 3. A placement groove 5 is provided at the top of the placement plate 4, and a placement tray 6 is provided in the placement groove 5. A liftable lifting plate 7 is provided inside the test chamber 2 and above the placement plate 4. A groove is provided at the bottom of the lifting plate 7, and multiple high-intensity lamps 8 are fixedly installed in the groove. By adjusting the position and height of the lifting plate 7 inside the test chamber 2, the distance between the multiple high-intensity lamps 8 at the bottom of the lifting plate 7 and the placement tray 6 can be changed. In this way, the test medicine in the placement tray 6 can be irradiated with high-intensity light at different distances, so as to test the effect of irradiating the medicine at different distances.

[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the lifting plate 7 has through holes 9 at each of its four corners, and the four through holes 9 on the lifting plate 7 are respectively movably fitted onto the four positioning posts 3. The lifting plate 7 is fixedly installed on both sides, and the lifting plate 7 can be moved up and down along the direction of the positioning posts 3 in the test chamber 2 by operating the driving mechanism.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the driving mechanism includes a fixed block 12, a motor 13, and a screw 14. The fixed block 12 is fixedly installed at the center of both sides of the lifting plate 7. A through screw hole is opened on the top of the fixed block 12. The motor 13 is fixedly installed on the top of the main body 1. The screw 14 is threaded into the screw hole on the fixed block 12. The top end of the screw 14 is fixedly connected to the output end of the motor 13, and the bottom end of the screw 14 is rotatably connected to the placement plate 4. By operating the motor 13, the screw 14 can be driven to rotate threadedly with the screw hole on the fixed block 12 at both ends of the lifting plate 7. Thus, by operating the two motors 13 on the main body 1 at the same time, the lifting plate 7 can be driven to move up and down in the direction of the positioning column 3 within the test chamber 2.

The bottom ends of the screws 14 in the two transmission mechanisms are respectively fixedly connected to the inner ring walls of the two bearings 15. The bearings 15 can fix the position of the bottom ends of the screws 14, making the screws 14 more stable when rotating, thereby increasing the stability of the lifting plate 7 when it moves up and down in the test chamber 2.

[0023] like Figure 3 and Figure 5 As shown, the bottom of the storage trough 5 has a slot through which the storage plate 4 passes. Multiple horizontal fixed shafts 10 are fixedly installed in the slot. Rollers 11 are rotatably sleeved on each fixed shaft 10. The top of each roller 11 extends out of the slot and abuts against the bottom of the storage tray 6. When the storage tray 6 is placed into the storage trough 5, the bottom of the storage tray 6 will contact the top of several rollers 11 in the slot. The rollers 11 will rotate on the fixed shafts 10. Therefore, it is easier to put on and take off the storage tray 6 during the experiment.

[0024] like Figure 1 and Figure 2 As shown, a flip-up door 16 is provided at the opening of the test chamber 2. Two hinges 17 are fixedly installed between one end of the door 16 and the outer wall of the main body 1. The door 16 can be hinged to the opening of the test chamber 2 through the hinges 17.
