Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical storage devices, specifically a pharmaceutical storage device for use in a chemical laboratory. Background Technology

[0002] Chemical experiments typically require a large number of chemical reagents. When these reagents are no longer needed, a reagent storage device is required to store them in the chemical laboratory.

[0003] Current chemical laboratory reagent storage devices, such as the one disclosed in CN221433091U, include a storage cabinet with a movable door at the center of its front outer surface. The cabinet's interior features a sliding pull-out structure for improved retrieval convenience. Inside the sliding pull-out structure is a clamping anti-shake reagent bottle fixing device for enhanced stability and ease of use. This clamping anti-shake reagent bottle fixing device includes a sponge placement groove, a reagent bottle body, and an electric push rod. The chemical laboratory reagent storage device of this invention, with its clamping anti-shake reagent bottle fixing device, has a simple structure and a high degree of automation. It not only improves the convenience of fixing the reagent bottle body during storage and enhances the ease of use of the device, but also improves the stability of the reagent bottle body during storage, preventing breakage due to shaking or impact during transportation and thus enhancing the protection of the reagent bottle body.

[0004] Existing chemical laboratory reagent storage devices, while preventing breakage from shaking and impacts during transport and improving the protection of reagent bottles, have proven ineffective in separating different types of chemicals stored in the same enclosed space. This poses a safety hazard. Furthermore, some chemicals require cryogenic storage, making these storage devices unsuitable for such applications. Therefore, we propose a new reagent storage device for chemical laboratories to address these issues. Utility Model Content

[0007] A temperature sensor is installed inside the storage tank, a controller is installed on the outside of the box, a connecting groove is opened inside the box away from the opening of the storage tank, heat dissipation holes are symmetrically opened on the outer wall of the box corresponding to the connecting groove, a heat conduction plate groove is opened on the inner end of the storage tank corresponding to the connecting groove, a heat conduction plate is installed in the heat conduction plate groove, and a semiconductor cooling chip is installed on the side of the heat conduction plate located in the connecting groove.

[0008] The semiconductor cooling chip has heat dissipation fins installed on the side away from the heat-conducting plate. A sealing cover is installed at the opening of the storage tank. The sealing cover is sealed to the insulation layer by a sealing ring. A bracket is fixedly connected to the lower side of the sealing cover near the inside of the storage tank. A limiting frame is fixedly connected to the upper side of the sealing cover near the bracket. The bracket and the limiting frame are slidably connected to the inner wall of the storage tank by a sliding mechanism. Placement slots are symmetrically penetrating the limiting frame. A clamping mechanism is provided below the placement slots on the limiting frame. The sealing cover is detachably connected to the housing by a locking mechanism.

[0009] Preferably, the sliding mechanism includes a slide rail, and slide rails are symmetrically installed on the inner walls of the storage tank corresponding to the bracket and the limiting frame on both sides. A slide groove is opened on the side of the slide rail away from the inner wall of the storage tank, and a slider is fixedly connected to the side of the bracket and the limiting frame corresponding to the slide groove.

[0010] Preferably, the clamping mechanism includes a fixed frame, and the limiting frame is symmetrically fixedly connected to the two sides below the placement slot. A clamping frame is provided on the side of the fixed frame near the placement slot. A guide rod slot passes through the fixed frame. A guide rod is fixedly connected to the side of the clamping frame corresponding to the guide rod slot. A first spring is sleeved on the guide rod between the clamping frame and the fixed frame. A baffle is fixedly connected to the end of the guide rod away from the clamping frame.

[0011] Preferably, the guide rod is rectangular columnar, and the external dimensions of the guide rod match the internal dimensions of the guide rod groove.

[0012] Preferably, the locking mechanism includes a handle, the outer side of the sealing cover is rotatably connected to the handle, the sealing cover has a rotating groove inside the handle corresponding to the handle, a rotating block is fixedly connected to one side of the handle corresponding to the rotating groove, the sealing cover has symmetrical locking rod grooves on the upper and lower sides, the storage slot has a locking groove on the inner wall corresponding to the locking rod groove, the rotating groove and the locking rod groove are connected by a pull rope groove, a second spring is installed in the locking rod groove, a locking rod is installed at the opening of the second spring corresponding to the locking rod groove, and the locking rod and the rotating block are fixedly connected by a pull rope.

[0013] Preferably, the locking rod is a rectangular column, and the external dimensions of the locking rod match the internal dimensions of the locking rod groove and the locking groove, and the inner side of the end of the locking rod away from the second spring is curved.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, when chemical reagents need to be stored, uses a sealing cap to move a bracket and a limiting frame out of the storage tank via a sliding mechanism. The reagent bottle is then placed in the placement slot and on the bracket, and a clamping mechanism secures the bottle. The sealing cap then pushes the bracket and limiting frame back into the storage tank. Multiple storage tanks allow for the separate storage of various chemical reagents. Furthermore, the semiconductor cooling chip and heat-conducting plate, along with a temperature sensor and controller, allow for temperature control within each storage tank, thus enabling the storage of different chemical reagents and effectively improving the practicality of the reagent storage device.

[0016] In this invention, when a medicine bottle is inserted into a placement slot, the bottom of the medicine bottle is supported by a bracket, while the clamping frame is tightly pressed against the outside of the medicine bottle by a first spring. The clamping frames on both sides of the medicine bottle can limit the position of the medicine bottle, thereby enabling the storage of medicine bottles of different sizes.

[0017] In this invention, when medicine bottles need to be picked up or put down, the handle drives the rotating block to rotate, causing the rotating block to move out of the locking groove through the pull rope, overcoming the elastic force of the second spring. This allows the sealing cap, along with the bracket and the limiting frame, to move out of the storage slot. After the medicine bottle is picked up or put down, the sealing cap is pushed. When the curved surface of the locking rod abuts against the box body, the locking rod retracts into the locking rod groove, overcoming the elastic force of the second spring. After the locking rod groove and the locking groove are aligned, the second spring pushes the locking rod into the locking groove, fixing the position of the sealing cap and preventing the bracket and the limiting frame from moving. Through this locking mechanism, the bracket and the limiting frame can be quickly pulled out or limited for picking up and putting down medicine bottles. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a reagent storage device for a chemical laboratory, comprising a box body 1, storage slots 2 evenly spaced on one side of the box body 1, and a heat insulation layer 3 provided on the inner wall of the storage slots 2.

[0027] A temperature sensor 4 is installed inside the storage tank 2, a controller 5 is installed on the outside of the housing 1, a connecting groove 6 is opened inside the housing 1 away from the opening of the storage tank 2, heat dissipation holes 7 are symmetrically opened on the outer wall of the housing 1 corresponding to the connecting groove 6, a heat conduction plate groove 8 is opened on the inner end of the storage tank 2 corresponding to the connecting groove 6, a heat conduction plate 9 is installed in the heat conduction plate groove 8, and a semiconductor cooling chip 10 is installed on the side of the heat conduction plate 9 located in the connecting groove 6.

[0028] A heat dissipation fin 11 is installed on the side of the semiconductor cooling chip 10 away from the heat conduction plate 9. A sealing cover 12 is installed at the opening of the storage tank 2. The sealing cover 12 is sealed to the insulation layer 3 through a sealing ring 13. A bracket 14 is fixedly connected to the lower side of the sealing cover 12 near the inside of the storage tank 2. A limit frame 15 is fixedly connected to the upper side of the sealing cover 12 near the bracket 14. The bracket 14 and the limit frame 15 are slidably connected to the inner wall of the storage tank 2 through a sliding mechanism. A placement groove 19 is symmetrically passed through the limit frame 15. A clamping mechanism is provided on the limit frame 15 below the placement groove 19. The sealing cover 12 is detachably connected to the box body 1 through a locking mechanism.

[0029] When chemical reagents need to be stored, the sealing cap 12 drives the bracket 14 and the limiting bracket 15 to move out of the storage tank 2 through the sliding mechanism. The reagent bottle is placed in the placement slot 19 and the bracket 14, and the reagent bottle is clamped and fixed with the clamping mechanism. Then, the sealing cap 12 pushes the bracket 14 and the limiting bracket 15 into the storage tank 2. By setting multiple storage tanks 2, various chemical reagents can be stored separately. The storage temperature in a single storage tank 2 can be controlled by the semiconductor cooling chip 10 and the heat conduction plate 9, together with the temperature sensor 4 and the controller 5. The semiconductor cooling chip 10 and the temperature sensor 4 are electrically connected to the controller 5 (the temperature sensor 4 is a commonly used temperature detection device, so its model is not specified and is directly quoted). The controller 5 controls the operation of the semiconductor cooling chip 10, and the heat dissipation fins 11 and heat dissipation holes 7 dissipate heat from the hot end of the semiconductor cooling chip 10. Thus, it can be used for chemical reagents with different storage requirements, effectively improving the practicality of the reagent storage device.

[0030] Please see Figures 1 to 6 The sliding mechanism includes a slide rail 16. The slide rail 16 is symmetrically installed on the inner walls of the storage tank 2 corresponding to the bracket 14 and the limiting frame 15. A groove 17 is opened on the side of the slide rail 16 away from the inner wall of the storage tank 2. A slider 18 is fixedly connected to the bracket 14 and the limiting frame 15 on the side corresponding to the groove 17. When the sealing cover 12 moves the bracket 14 and the limiting frame 15, the bracket 14 and the limiting frame 15 move the slider 18 in the groove 17. Through the sliding connection formed by the groove 17 and the slider 18, the sliding stroke of the bracket 14 and the limiting frame 15 can be limited, and the movement of the bracket 14 and the limiting frame 15 can be prevented from deviating.

[0031] Please see Figures 1 to 6 The clamping mechanism includes a fixed frame 20. The limiting frame 15 is symmetrically fixedly connected to the fixed frame 20 on both sides below the placement slot 19. A clamping frame 21 is provided on the side of the fixed frame 20 near the placement slot 19. A guide rod slot 22 passes through the fixed frame 20. A guide rod 23 is fixedly connected to the side of the clamping frame 21 corresponding to the guide rod slot 22. A first spring 24 is sleeved on the guide rod 23 between the clamping frame 21 and the fixed frame 20. A baffle 25 is fixedly connected to the end of the guide rod 23 away from the clamping frame 21. The guide rod 23 is rectangular columnar, and the external dimensions of the guide rod 23 match the internal dimensions of the guide rod slot 22. When the medicine bottle is inserted into the placement slot 19, the bottom of the medicine bottle is supported by the bracket 14. At the same time, the clamping frame 21 is tightly pressed against the outside of the medicine bottle by the first spring 24. The clamping frames 21 on both sides of the medicine bottle can limit the position of the medicine bottle, thereby enabling the storage of medicine bottles of different sizes.

[0032] Please see Figures 1 to 6The locking mechanism includes a handle 26. The handle 26 is rotatably connected to the outside of the sealing cover 12. The sealing cover 12 has a rotating groove 27 corresponding to the inside of the handle 26. A rotating block 28 is fixedly connected to one side of the handle 26 corresponding to the rotating groove 27. The sealing cover 12 has symmetrical locking rod grooves 29 on its upper and lower sides. The storage slot 2 has a locking groove 30 corresponding to the inner wall of the locking rod groove 29. The rotating groove 27 and the locking rod groove 29 are connected by a pull rope groove 31. A second spring 32 is installed in the locking rod groove 29. A locking rod 33 is installed at the opening of the second spring 32 corresponding to the locking rod groove 29. The locking rod 33 is fixedly connected to the rotating block 28 by a pull rope 34. The locking rod 33 is rectangular and its external dimensions match the internal dimensions of the locking rod groove 29 and the locking groove 30. The end of the locking rod 33 away from the second spring 32 is also fixedly connected. The inner side is curved. When it is necessary to pick up or put down the medicine bottle, the handle 26 drives the rotating block 28 to rotate. The rotating block 28 drives the locking rod 33 to move out of the locking groove 30 through the pull rope 34, overcoming the elastic force of the second spring 32. This allows the sealing cover 12, along with the bracket 14 and the limiting frame 15, to move out of the storage slot 2. After the medicine bottle is picked up or put down, the sealing cover 12 is pushed. When the curved surface of the locking rod 33 abuts against the box body 1, the locking rod 33 retracts into the locking rod groove 29, overcoming the elastic force of the second spring 32. After the locking rod groove 29 and the locking groove 30 are aligned, the second spring 32 pushes the locking rod 33 into the locking groove 30, fixing the position of the sealing cover 12 and preventing the bracket 14 and the limiting frame 15 from moving. Through this locking mechanism, the bracket 14 and the limiting frame 15 can be quickly pulled out or limited to facilitate the picking up and putting down of the medicine bottle.

[0033] Working Principle: This is a reagent storage device for chemical laboratories. When chemical reagents need to be stored, the sealing cover 12 drives the bracket 14 and the limiting frame 15 to move out of the storage tank 2 through the sliding mechanism. The reagent bottle is placed in the placement slot 19 and the bracket 14, and the reagent bottle is clamped and fixed with the clamping mechanism. Then, the sealing cover 12 pushes the bracket 14 and the limiting frame 15 into the storage tank 2. By setting multiple storage tanks 2, various chemical reagents can be stored separately. The storage temperature in a single storage tank 2 can be controlled by the semiconductor cooling chip 10 and the heat conduction plate 9, together with the temperature sensor 4 and the controller 5. The semiconductor cooling chip 10 and the temperature sensor 4 are electrically connected to the controller 5 (the temperature sensor 4 is a commonly used temperature detection device, so its model is not specified and is directly quoted). The controller 5 controls the operation of the semiconductor cooling chip 10, and the heat dissipation fins 11 and heat dissipation holes 7 dissipate heat from the hot end of the semiconductor cooling chip 10, thereby making it suitable for storing different chemical reagents and effectively improving the practicality of the reagent storage device.

[0034] When the sealing cap 12 moves the bracket 14 and the limiting frame 15, the bracket 14 and the limiting frame 15 move the slider 18 within the groove 17. The sliding connection formed by the groove 17 and the slider 18 limits the travel of the bracket 14 and the limiting frame 15, preventing them from shifting. When the medicine bottle is inserted into the placement slot 19, the bracket 14 supports the bottom of the bottle, while the clamping frame 21, via the first spring 24, firmly abuts against the outside of the bottle. The clamping frames 21 on both sides of the bottle limit its position, allowing for the storage of medicine bottles of different sizes. When the bottle needs to be retrieved, the handle 26 drives the rotating block 28. Rotating the rotating block 28 causes the locking rod 33 to move out of the locking groove 30 through the pull rope 34, overcoming the elastic force of the second spring 32. This allows the sealing cover 12, along with the bracket 14 and the limiting frame 15, to move out of the storage compartment 2. After the medicine bottle is removed or placed, pushing the sealing cover 12 causes the locking rod 33 to retract into the locking rod groove 29 when its curved surface abuts against the box body 1. After the locking rod groove 29 aligns with the locking groove 30, the second spring 32 pushes the locking rod 33 into the locking groove 30, fixing the position of the sealing cover 12 and preventing the bracket 14 and the limiting frame 15 from moving. This locking mechanism allows the bracket 14 and the limiting frame 15 to be quickly pulled out or limited, facilitating the removal and placement of medicine bottles.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
