Description

Technical Field

[0001] This utility model relates to the field of light shielding for reagents and auxiliaries, and in particular to a light shielding storage device for chemical reagents and auxiliaries. Background Technology

[0002] In chemical experiments, industrial production, and laboratory management, many chemical reagents and auxiliaries are photosensitive. Light exposure can accelerate their decomposition, deterioration, or alteration of their properties, thereby affecting experimental results or product quality. Therefore, for such photosensitive chemical reagents or auxiliaries, effective light-shielding measures must be taken for storage to extend their shelf life and ensure their performance stability. Currently, light-shielding storage devices are commonly used on the market to store photosensitive chemical reagents or auxiliaries.

[0003] However, some existing light-shielding storage devices still have some problems in practical use. For example, in actual use, the device needs to store a large number of reagents or auxiliaries, making it difficult for users to retrieve reagents or auxiliaries placed deep inside the device. Even if they can reach inside, they may find it difficult to operate due to the narrow space, obstructed vision, or the need to move reagents in front. They may also accidentally bump into other reagent bottles, causing them to tip over, break, leak, contaminate, or even cause safety accidents. At the same time, the angle of the light shield in some existing light-shielding storage devices is usually fixed and cannot be adjusted. However, the lighting environment in laboratories or production workshops is not completely consistent, and the position, angle, and intensity of light sources may vary. A fixed angle of the light shield may not be able to fully adapt to different lighting conditions, resulting in an inability to effectively block all light entering the device. Especially when the angle of the light source is inconsistent with the preset angle of the light shield, the light may bypass the light shield and shine on the reagents or auxiliaries inside, thereby reducing the light-shielding effect and failing to fully protect photosensitive substances. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a light-shielding storage device for chemical reagents and auxiliaries, comprising a storage device body 1. Hinges 10 are fixedly connected to the left and right sides of the top of the storage device body 1. A cover 2 is rotatably connected to the outer walls of the two hinges 10. Second storage tubes 16 are fixedly connected to the left and right sides of the rear end of the inner wall of the storage device body 1. Second compression springs 17 are fixedly connected to the inner walls of the second storage tubes 16. A locking block 9 is fixedly connected to the outer wall of the second compression spring 17, and the outer wall of the locking block 9 is used to lock the cover 2. A magnetic adhesive is fixedly connected to the bottom end of the cover 2, and the cover 2 is magnetically secured to the outer wall of the storage device body 1. A handle is fixedly connected to the rear end of the outer wall of the cover 2, and the handle is used to pull the cover 2. The left and right sides of the inner wall of the cover 2... A base block 3 is fixedly connected, and a connecting rod 18 is rotatably connected to the outer wall of the base block 3. A connecting plate 4 is rotatably connected to the outer wall of the connecting rod 18. An unfolding assembly is provided on the outside of the connecting plate 4. The connecting plate 4 moves the storage compartment 8 out of the device through the unfolding assembly. The unfolding assembly includes a first compression spring 14 fixedly connected to the outer wall of the connecting plate 4. A first compression spring 14 is fixedly connected to the outer wall of the first compression spring 14. A first storage tube 15 is fixedly connected to the outer wall of the first compression spring 14. The outer wall of the first storage tube 15 is fixedly connected to the front end of the inner wall of the storage device body 1. The bottom end of the connecting plate 4 is fixedly connected to the storage compartment 8. The storage compartment 8 is provided with several placement slots inside. The placement slots are used to place chemical reagents or auxiliaries. The outer wall of the connecting plate 4 slides on the inner wall of the storage device body 1.

[0024] Specifically, when the user needs to remove the device, they grasp the handle to open the cover 2 outwards. As the cover 2 opens, it moves the bottom blocks 3 on both sides outwards, which in turn pulls the connecting rod 18 outwards. The movement of the connecting rod 18 then moves the connecting plate 4 outwards, causing the connecting plate 4 to slide within the inner wall of the storage device body 1. Simultaneously, the first compression spring 14 is stretched. Through this series of actions, the two connecting plates 4, along with the storage compartment 8, slide out of the storage device body 1. Then, as the cover 2 opens, the second compression spring 17 at the rear end of the locking block 9 begins to rebound, thus removing the storage compartment 8. The locking block 9 pops outward, and when the cover 2 is fully unfolded to the top, completely opening the space in the storage device body 1, the locking block 9 locks the bottom of the cover 2, preventing the cover 2 from suddenly slipping off and ensuring operational safety. Then, the user places the chemical reagents and auxiliaries into the storage compartment 8. After placement, the user presses the locking block 9 into the interior of the storage device body 1 to release the restriction on the cover 2. At the same time, the first compression spring 14 rebounds, reversing the above structure and allowing the storage compartment 8, along with the reagents and auxiliaries inside, to enter the storage device body 1, completing the reagent storage.

[0025] Reference Figures 2-4A light-shielding plate 11 is rotatably connected to the top of the inner wall of the storage device body 1. Fixing posts are fixedly connected to both the left and right sides of the light-shielding plate 11. A round tube 12 is fixedly connected to the outer wall of the left fixing post. A locking assembly is provided on the outside of the round tube 12. The locking assembly includes a turntable 5 fixedly connected to the outer wall of the round tube 12. A locking piece 7 is locked on the inner wall of the turntable 5. A tension spring 13 is fixedly connected to the outer wall of the locking piece 7. An inner tube is fixedly connected to the outer wall of the tension spring 13. The outer wall of the inner tube is rotatably connected to the inner wall of the round tube 12. Several slots 6 are opened on the inner wall of the turntable 5. The size of the slots 6 is adapted to the locking piece 7. The fixing posts on both the left and right sides are rotatably connected to the top of the inner wall of the storage device body 1. The light-shielding plate 11 is rotatably connected to the storage device body 1 through the fixing posts.

[0026] Specifically, depending on the actual lighting conditions, the user needs to pull out the clip 7 to remove it from the slot 6 in the turntable 5, and at the same time stretch the tension spring 13 to release the restriction on the turntable 5. In this way, the user can rotate the light shield 11, so that the light shield 11 and the turntable 5 rotate to the most suitable light shielding angle. After the adjustment is completed, release the user to allow the clip 7 to be inserted into the corresponding slot 6 to complete the limit and ensure that the light shield 11 is in the appropriate position to block the light.

[0027] Working principle: The user takes out the device and then grasps the handle, causing the cover 2 to open outwards. This moves the bottom blocks 3 on both sides outwards, causing the bottom blocks 3 to pull the connecting rod 18 outwards. The connecting rod 18 then moves the connecting plate 4 outwards, causing the connecting plate 4 to slide within the inner wall of the storage device body 1, stretching the first compression spring 14. The movement of the connecting plate 4 causes the two connecting plates 4, along with the storage compartment 8, to slide out of the storage device body 1. Simultaneously, as the cover 2 opens, the rear end of the locking block 9... The second spring 17 rebounds and pushes the locking block 9 outward. Then, when the cover 2 is fully opened to the top and the space in the storage device body 1 is fully opened, the locking block 9 locks the bottom of the cover 2 to prevent the cover 2 from suddenly slipping off. Then, after the user places the chemical reagents and auxiliaries in the storage compartment 8, the locking block 9 is pressed into the inside of the storage device body 1 to release the restriction on the cover 2. At the same time, the first spring 14 rebounds and reverses the above structure, so that the storage compartment 8, with the reagents and auxiliaries inside, enters the storage device body 1.

[0028] Then, according to the actual lighting conditions, the user pulls out the clip 7, causing it to move out of the slot 6 in the turntable 5 and simultaneously stretching the tension spring 13 to release the restriction on the turntable 5. Then, the user can rotate the light-shielding plate 11, causing the light-shielding plate 11 to rotate with the turntable 5 to the most suitable light-shielding angle. Then, the user releases the user's hand to allow the clip 7 to be inserted into the corresponding slot 6 to complete the limiting.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
