Description

Technical Field

[0001] This utility model belongs to the technical field of laboratory safety cabinets, specifically relating to a fireproof laboratory safety cabinet. Background Technology

[0002] Laboratory fireproof safety cabinets, also known as chemical cabinets, safety cabinets, or flammable liquid storage cabinets, are devices specifically designed to provide safe storage, dispensing, and classified management of hazardous chemicals. Laboratory fireproof safety cabinets can provide a safe and reliable storage environment for hazardous chemicals, preventing dangerous events such as fires and explosions caused by accidental leakage, volatilization, or mishandling.

[0003] For example, Chinese Patent CN216166262U discloses a laboratory fireproof and explosion-proof safety cabinet. Its structure includes a cabinet body and a hinged door. The cabinet body has several ventilation holes communicating with its internal space. A sealing assembly is installed inside the cabinet to close the ventilation holes. The sealing assembly is suspended inside the cabinet via a connector, which is flammable. During use, in the event of a fire in the laboratory, the flames burn through the connector, causing the sealing assembly to fall and form a sealed space that isolates chemical agents, preventing the flames from entering and effectively preventing further damage.

[0004] Specifically, given the complex environment in which laboratory biosafety cabinets operate, they are often used to store large quantities of test tubes and various types of vials. However, it is worth noting that most of these test tubes are made of fragile glass. Unfortunately, traditional laboratory biosafety cabinets often lack effective safety protection measures for these glass items in their design and functionality. Therefore, when glass test tubes are placed in such biosafety cabinets, they are highly susceptible to breakage due to various reasons (such as vibration, improper handling, or environmental factors). This not only leads to waste of experimental materials but may also adversely affect the overall structure and performance of the biosafety cabinet, thereby impacting the overall safety and efficiency of the laboratory.

[0005] The purpose of this invention is to provide a fireproof laboratory safety cabinet, addressing the issue that, given the complex environmental factors in which laboratory safety cabinets are often used to store large quantities of test tubes and various experimental vials, it is worth noting that most of these test tubes are made of fragile glass. Unfortunately, traditional laboratory safety cabinets often lack effective safety protection measures for such glass products in their design and function. Therefore, when glass test tubes are placed in such safety cabinets, they are highly susceptible to breakage due to various reasons (such as vibration, improper operation, or environmental factors). This not only leads to the waste of experimental materials but may also adversely affect the overall structure and performance of the safety cabinet, thereby impacting the overall safety and work efficiency of the laboratory.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof safety cabinet for laboratories, comprising a fireproof safety cabinet body and a cabinet door connected to the fireproof safety cabinet body and the cabinet door on one side by hinges, wherein the fireproof safety cabinet body has heat dissipation holes on its side and the inner wall of the fireproof safety cabinet body is filled with asbestos board;

[0007] The fireproof safety cabinet has a partition installed inside. A test tube placement plate is connected to the surface of the partition.

[0009] To facilitate the protection of experimental test tubes, the protective flaps of this fireproof laboratory safety cabinet are preferably made of rubber, and each test tube placement opening is connected to six protective flaps.

[0010] To facilitate the stable assembly of the test tube protection plate, in a preferred embodiment of this utility model of a laboratory fireproof safety cabinet, the positioning spring and the positioning buckle form an elastic telescopic structure, and the positioning buckle and the opening on one side of the support frame form an interlocking structure.

[0011] To facilitate the absorption of moisture inside the fireproof safety cabinet, in a preferred embodiment of this utility model of a laboratory fireproof safety cabinet, an assembly plate is connected to the top of the inner wall of the fireproof safety cabinet, and a moisture-proof board is connected to one side of the assembly plate. The moisture-proof board is filled with melamine material.

[0012] To facilitate the assembly of the moisture-proof board, in a preferred embodiment of the laboratory fireproof safety cabinet of this utility model, the moisture-proof board is connected to assembly blocks at both ends near the assembly board, and the assembly board is connected to sliding blocks near the inner wall of the assembly blocks.

[0013] To facilitate the stable installation of the moisture-proof board, in a preferred embodiment of this utility model of a laboratory fireproof safety cabinet, the assembly block has a sliding groove on its bottom surface near the sliding block, and the assembly block and the sliding block form a sliding connection structure through the sliding groove. A locking bolt is connected through the bottom surface of the assembly board.

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

[0015] This invention involves placing a test tube placement plate on the surface of a partition, then connecting four mounting blocks at both ends of the test tube protection plate to four support frames. This causes the positioning buckle to compress the positioning spring, resulting in deformation of the positioning spring. The mounting blocks are then installed and stabilized on the top of the support frames, facilitating the stable installation of the test tube protection plate. Afterwards, the experimenter places the bottom end of a glass test tube through the protective flap and securely places it at the opening on the surface of the test tube placement plate. During this process, the protective flap compresses and protects the test tube, preventing it from shaking and breaking within the fireproof safety cabinet, thus improving the practicality of the fireproof safety cabinet.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a laboratory fireproof safety cabinet, including a fireproof safety cabinet body 1 and a cabinet door 2 connected to the fireproof safety cabinet body 1 and the cabinet door 2 by a hinge. The fireproof safety cabinet body 1 has heat dissipation holes 3 on its side and the inner wall of the fireproof safety cabinet body 1 is filled with asbestos board. The use of asbestos board improves the fireproof effect of the fireproof safety cabinet body 1.

[0026] The fireproof safety cabinet 1 has a partition 4 installed inside. A test tube placement plate 5 is connected to the surface of the partition 4. Support frames 6 are connected to the four corners of the surface of the test tube placement plate 5. A test tube protection plate 7 is set at the top of the test tube placement plate 5. A protective flap 8 is installed on the inner wall of the opening of the surface of the test tube protection plate 7. Mounting blocks 9 are connected to the two ends of the surface of the test tube protection plate 7 near the support frame 6. A positioning spring 10 is connected to the inner wall of the opening of the mounting block 9. A positioning buckle 11 is connected to the other end of the positioning spring 10.

[0027] Preferably, the test tube placement plate 5 and the test tube protection plate 7 are made of PVC, and the surface of the test tube protection plate 7 has test tube placement openings of different sizes. The protective flaps 8 are made of rubber, and each test tube placement opening is connected to six protective flaps 8. In actual use, the protective flaps 8 facilitate the placement and protection of experimental test tubes, preventing damage due to shaking and avoiding waste of reagents.

[0028] Preferably, the positioning spring 10 and the positioning buckle 11 form an elastic telescopic structure, and the positioning buckle 11 and the opening on one side of the support frame 6 form a fitting structure. In actual use, the rebound force of the positioning spring 10 drives the positioning buckle 11 to fit into the opening on one side of the support frame 6, thereby facilitating the stable installation of the test tube protection plate 7.

[0029] Preferably, the top of the inner wall of the fireproof safety cabinet 1 is connected to an assembly board 12, and one side of the assembly board 12 is connected to a moisture-proof board 13, the interior of which is filled with melamine material. In actual use, the moisture-proof board 13 facilitates the absorption of moisture inside the fireproof safety cabinet 1.

[0030] Preferably, the moisture-proof board 13 is connected to assembly blocks 14 at both ends near the assembly board 12, and the assembly board 12 is connected to the inner wall of the assembly blocks 14 by sliding blocks 15. In actual use, the moisture-proof board 13 is easily assembled by sliding the assembly blocks 14 at both ends of the moisture-proof board 13 along the sliding blocks 15, which also facilitates quick replacement or assembly later.

[0031] Preferably, the bottom surface of the assembly block 14 near the sliding block 15 has a sliding groove 16, and the assembly block 14 and the sliding block 15 form a sliding connection structure through the sliding groove 16. A locking bolt 17 is connected through the bottom surface of the assembly plate 12. In actual use, the locking bolt 17 is threaded through the assembly plate 12 and the sliding block 15 and then threadedly connected to the assembly block 14, which facilitates the stable installation of the moisture-proof board 13. This allows the melamine material inside the moisture-proof board 13 to absorb moisture inside the fireproof safety cabinet 1, ensuring the efficacy of the medicines placed inside the fireproof safety cabinet 1 and improving the practicality of the fireproof safety cabinet 1.

[0032] The working principle of this utility model is as follows: The test tube placement plate 5 is placed on the surface of the partition plate 4. Then, the four mounting blocks 9 at both ends of the test tube protection plate 7 are connected to the four support frames 6, causing the positioning buckles 11 to compress the positioning springs 10, resulting in deformation of the springs 10. After the mounting blocks 9 are connected to the top of the support frames 6, the positioning buckles 11 fit into the opening on one side of the support frame 6, facilitating the stable installation of the test tube protection plate 7. Then, the experimenter places the bottom end of the glass test tube through the protective flap 8 and stably places it at the opening on the surface of the test tube placement plate 5. During this process, the protective flap 8 can compress and protect the test tube, preventing it from shaking and breaking within the fireproof safety cabinet 1. This design avoids waste of chemicals inside the laboratory safety cabinet and improves the practicality of the fireproof safety cabinet 1. Furthermore, by connecting the assembly blocks 14 at both ends of the moisture-proof board 13 to the assembly plate 12 at the top of the inner wall of the fireproof safety cabinet 1, it is easy to assemble the moisture-proof board 13 inside the fireproof safety cabinet 1. During this process, the sliding groove 16 on the bottom surface of the assembly block 14 slides along the sliding block 15. After the moisture-proof board 13 is slidably installed in place, the locking bolt 17 passes through the assembly plate 12 and the sliding block 15 and is threadedly connected to the assembly block 14, thus facilitating the quick and stable installation of the moisture-proof board 13. This also facilitates the absorption of moisture generated inside the fireproof safety cabinet 1, ensuring the efficacy of the chemicals inside the fireproof safety cabinet 1.
