Description

Technical Field

[0001] This utility model relates to the field of safety cabinet technology, specifically a fire-resistant safety cabinet. Background Technology

[0002] In environments with stringent safety requirements, such as laboratories, archives, and data centers, fire-resistant safety cabinets are used to store important assets such as documents, electronic devices, chemicals, and valuables. Their core function is to block flame attack through fire-resistant structures and ensure the survival time of the items inside. Existing fire-resistant safety cabinets typically include a cabinet body, an openable and closable fire-resistant cabinet door, and drawer assemblies inside the cabinet. The drawers of existing safety cabinets do not have any internal partitions or compartments, and all items are directly piled up in the same open space. Although this design simplifies the manufacturing process, there is no physical separation between items of different natures (such as flammable reagents, precision electronic equipment, paper documents, and corrosive chemicals), which can easily lead to mixed storage. If chemicals leak, they can directly corrode surrounding paper documents and electronic equipment, increasing the damage. In view of this, the present invention proposes a fire-resistant protective safety cabinet to solve the above-mentioned technical problems. Utility Model Content

[0003] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a fire-resistant safety cabinet. Firstly, the combination of horizontal and vertical partitions creates physical separation, allowing items of different properties, such as flammable reagents, precision electronic equipment, paper documents, and corrosive chemicals, to be placed in separate compartments, preventing direct contact due to the lack of separation. Secondly, the horizontal partitions are quickly installed via connecting grooves and limiting components, achieving stable fixation without complex tools. The vertical partitions are detachably fixed using a snap-fit ​​and threaded structure. Adjustment is simple: press the knob to release the snap-fit, push the partition to the target position, and release the knob to lock it in place. This design is simple and efficient. Furthermore, the number and size of the compartments within the drawer can be flexibly adjusted according to the size of the items, adapting to the storage needs of different sized items. Compared to existing fixed single-chamber structures, its practicality and adaptability are significantly improved.

[0004] This utility model provides the following technical solution: a fire-resistant safety cabinet, including a cabinet body, a cabinet door, and multiple drawers disposed inside the cabinet body; Each drawer has multiple symmetrical connecting slots on its top. The inner cavity of each connecting slot is detachably connected to a horizontal partition. Each horizontal partition has a sliding groove on its top. The top of the inner wall of the sliding groove is fixedly connected to multiple snap-fit ​​blocks a. Each of the horizontal partitions has multiple vertical partitions slidably connected to its top. Each of the vertical partitions has a connecting rod slidably connected to its inner cavity. One end of the connecting rod extends into a sliding groove, and the extended end of the connecting rod is fixedly connected to a connecting plate that matches the sliding groove. Multiple snap-fit ​​blocks b that match snap-fit ​​block a are fixedly connected to the top of the connecting plate. A knob is threaded onto the surface of the connecting rod, and a return spring is sleeved on the surface of the connecting rod between the knob and the top of the vertical partition.

[0005] As a preferred technical solution of this utility model, each of the inner walls of the connecting groove is provided with sliding holes on both sides, and a limiting block is slidably connected to the inner cavity of each sliding hole. A compression spring is provided between the limiting block and the inner cavity of the sliding hole, and each of the transverse partitions is provided with limiting holes adapted to the limiting block on both sides.

[0006] As a preferred technical solution of this utility model, the cabinet door is rotatably connected to the cabinet body through a rotating component, and a composite fire-resistant layer is fixedly connected to the end of the cabinet door facing the drawer.

[0007] As a preferred technical solution of this utility model, the composite fire-resistant layer is composed of an outer fireproof steel plate, a middle aluminum silicate fiber board and an inner fireproof and heat-insulating coating, and the fireproof and heat-insulating coating is applied to the side of the aluminum silicate fiber board facing the drawer.

[0008] As a preferred embodiment of this utility model, both the snap-fit ​​block a and the snap-fit ​​block b are triangular protrusion structures, and the inclined surface of snap-fit ​​block a and the inclined surface of snap-fit ​​block b are in contact with each other.

[0016] 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.

[0017] Please see Figure 1-5 As shown, a fire-resistant safety cabinet includes a cabinet body 1, a cabinet door 101, and a plurality of drawers 102 disposed inside the cabinet body 1; Each drawer 102 has multiple connecting slots 2 symmetrically opened on its top. The inner cavity of each connecting slot 2 is detachably connected to a horizontal partition 201. Each horizontal partition 201 has a sliding groove 202 opened on its top. Multiple snap-fit ​​blocks a203 are fixedly connected to the top of the inner wall of the sliding groove 202. Each horizontal partition 201 has multiple vertical partitions 204 slidably connected to its top. Each vertical partition 204 has a connecting rod 205 slidably connected to its inner cavity. One end of the connecting rod 205 extends into the sliding groove 202, and the extended end of the connecting rod 205 is fixedly connected to a connecting plate 206 that is adapted to the sliding groove 202. Multiple snap-fit ​​blocks b207 that are adapted to snap-fit ​​blocks a203 are fixedly connected to the top of the connecting plate 206. A knob 208 is threadedly connected to the surface of the connecting rod 205. A return spring 209 is sleeved on the surface of the connecting rod 205 between the knob 208 and the top of the vertical partition 204.

[0018] Each connecting groove 2 has sliding holes 3 on both sides of its inner wall. Each sliding hole 3 has a slidable limit block 301 in its inner cavity. A compression spring 302 is provided between the limit block 301 and the inner cavity of the sliding hole 3. Each transverse partition 201 has a limit hole 303 on both sides that is adapted to the limit block 301.

[0019] Cabinet door 101 is rotatably connected to cabinet body 1 via a rotating component, and a composite fire-resistant layer 4 is fixedly connected to the end of cabinet door 101 facing drawer 102.

[0020] The composite fire-resistant layer 4 consists of an outer fireproof steel plate, a middle aluminum silicate fiberboard, and an inner fireproof and heat-insulating coating, with the fireproof and heat-insulating coating applied to the side of the aluminum silicate fiberboard facing the drawer 102.

[0021] Both the snap-fit ​​block a203 and the snap-fit ​​block b207 are triangular protrusion structures, and the inclined surface of the snap-fit ​​block a203 and the inclined surface of the snap-fit ​​block b207 fit together.

[0022] The exposed end of the limiting block 301 is a hemispherical structure, and the limiting hole 303 is a hemispherical groove that is adapted to the limiting block 301. The outer diameter of the limiting block 301 is adapted to the inner diameter of the limiting hole 303.

[0023] The surface of the knob 208 is provided with anti-slip texture, which is a series of concave grooves spaced along the circumference of the knob 208.

[0024] The two ends of the return spring 209 abut against the top of the vertical partition 204 and one end of the knob 208, respectively.

[0025] The horizontal partition 201 forms the basic framework for the partitioning of drawer 102, and its installation relies on the cooperation between the connecting groove 2 and the limiting component to achieve stable fixation. Align both ends of the horizontal partition 201 with the pre-set connecting groove 2 at the top of the drawer 102, and push it into the inner cavity of the connecting groove 2 in a horizontal direction. At this time, the side of the horizontal partition 201 will contact the limiting block 301 in the sliding hole 3 on the inner wall of the connecting groove 2; The limiting block 301 has a hemispherical structure. After being squeezed by the transverse partition 201, it will retract into the sliding hole 3 and compress the compression spring 302 (the compression spring 302 generates elastic potential energy), ensuring that the transverse partition 201 can be pushed in smoothly. When the transverse partition 201 is fully inserted into the connecting groove 2, the limiting holes 303 on both sides are exactly aligned with the sliding hole 3. The compression spring 302 releases its elastic potential energy, pushing the limiting block 301 to pop out and be inserted into the limiting hole 303. Since the outer diameter of the limiting block 301 is adapted to the inner cavity of the limiting hole 303, the transverse partition 201 is axially locked and cannot slide or disengage along the connecting groove 2, thus achieving stable installation. The vertical partition 204 and the horizontal partition 201 cooperate to form multiple zones, and their installation is achieved through snap-fit ​​and threaded fastening for easy removal and fixation. Place the vertical partition 204 on top of the horizontal partition 201, align the through hole of the inner cavity of the vertical partition 201 with the sliding groove 202 of the horizontal partition 201, and let the connecting rod 205 pass through the through hole of the vertical partition 204. The return spring 209 is fitted onto the part of the connecting rod 205 located above the vertical partition 204, and then the knob 208 is threadedly connected to the top of the connecting rod 205 (the concave anti-slip texture on the surface of the knob 208 can increase friction and make it easier to hold and operate). When the knob 208 is tightened, its lower end will compress the return spring 209 (spring compression stores energy), and at the same time drive the connecting rod 205 to lift the connecting plate 206 upward, so that the locking block b207 (triangular structure) at the top of the connecting plate 206 and the locking block a203 (also triangular structure) at the top of the sliding groove 202 engage with each other. Since the triangular structure has a one-way locking characteristic, the locking block a203 cannot slide laterally after it is in contact with the inclined surface of the locking block b207. The vertical partition 204 is fixed in the current position, forming a stable partition with the horizontal partition 201. To accommodate items of different sizes, the vertical divider 204 can be flexibly adjusted in spacing through unlocking, sliding, and locking. When adjustment is needed, press down on knob 208. Knob 208 overcomes the elastic force of return spring 209 and continues to compress the spring. At the same time, it drives connecting rod 205 to push connecting plate 206 downward, so that locking block b207 separates from locking block a203 (the inclined surface of the triangular structure facilitates separation). The lateral constraint of vertical partition 204 is released. Push the vertical partition 204 so that it slides along the top of the horizontal partition 201 until it reaches the desired position; Loosen knob 208, return spring 209 releases elastic potential energy, pushes knob 208 upward to reset, connecting rod 205 drives connecting plate 206 and snap-fit ​​block b207 to move upward, re-engage with snap-fit ​​block a203 corresponding to the current position, vertical partition 204 is fixed again, and spacing adjustment is completed; Cabinet door 101 is connected to cabinet body 1 via a rotating component. A composite fire-resistant layer 4 is fixed on the side of cabinet door 101 facing drawer 102. This layer consists of an outer fireproof steel plate (resisting direct burning by open flame), a middle aluminum silicate fiberboard (blocking heat conduction), and an inner fireproof and heat-insulating coating (delaying heat penetration), forming a three-level heat insulation barrier to reduce the rate at which high temperature is conducted into cabinet body 1. The horizontal partition 201, the vertical partition 204, and the connecting components (such as the limiting block 301 and the connecting rod 205) are all made of high-temperature resistant materials (such as fire-resistant alloys), which are not easily deformed in high-temperature environments, ensuring the stability of the partition structure, preventing items from being mixed due to partition failure, and maintaining protective order during fire.
