Description

Technical Field

[0001] This utility model relates to the field of fireproof cabinet technology, and in particular to a fireproof cabinet fusion component and a fireproof cabinet. Background Technology

[0002] Safety cabinets are safety protection products used to store various production or daily necessities or materials. Safety cabinets must not only meet the requirements of fire protection and safety laws and regulations, but also be convenient to open and close to retrieve items under normal circumstances, and ensure that the cabinet door is sealed in the event of a fire to isolate the external or internal fire in a timely manner, so as to protect the items inside or outside the cabinet to the greatest extent and keep them away from the hazards of fire.

[0003] For fireproof safety cabinets, it is essential to have an automatic door closing device that can be fixed at a certain angle to allow items to be retrieved under normal conditions, and can be easily pulled to close the door after retrieval. In the event of a fire, if the ambient temperature reaches a certain level, the door will automatically close in time even if the cabinet is in the open and closed position.

[0004] Currently, most automatic door closing devices in safety cabinets on the market use a fusible alloy with a fixed melting point. The fusible alloy solidifies, fusing two metal pieces together. One metal piece is fastened to the bottom of the clamping clip, and the other is fastened to the door. When a fire occurs, the ambient temperature reaches the melting point of the fusible alloy, causing it to melt and separate the two metal pieces. The door then automatically closes under the action of the door closer, with the clamping clip attached to the connecting rod. However, fixing and bonding the two metal pieces together with a suitable fusible alloy requires finding a specific manufacturer and paying considerable fees for custom molds and tooling fixtures. There are also minimum order quantities that are often several times higher than the actual usage, making it very inconvenient.

[0005] In view of this, there is an urgent need for a fireproof cabinet fusion assembly and a fireproof cabinet to solve the above problems. Summary of the Invention

[0006] To help solve the problems existing in the prior art, this utility model provides a fireproof cabinet fusible assembly and a fireproof cabinet, which adopts the following technical solution: including: a fixing plate, an elastic female end, an elastic male end, and two fusible sheet assemblies, wherein the elastic female end and the male end are elastically inserted into each other.

[0007] The elastic connection female end includes a first mounting base;

[0008] The two fuse assemblies are respectively placed at both ends of the first mounting base. Each fuse assembly includes a fuse, one end of which is connected to the fixing plate and the other end of which is connected to the first mounting base.

[0009] Its further feature is that,

[0010] The fuse assembly includes two fuses, one end of which is connected to the first mounting base, and the other end of which extends toward both sides of the first mounting base.

[0011] The first mounting base has first mounting holes at both ends, the fuse has second mounting holes at both ends, and the fixing plate has a plurality of third mounting holes. The two ends of the fuse are respectively fixed to the corresponding second mounting holes and the corresponding third mounting holes through the second mounting holes.

[0012] The elastic connecting female end also includes two elastic ball assemblies. Each elastic ball assembly includes an elastic element and a ball. The two balls are disposed opposite to each other on the first mounting base, and the two elastic elements are respectively disposed on the side of the two balls that are far apart from each other.

[0013] The elastic connector is provided with a locking head, and there are locking grooves on both sides of the locking head that are adapted to the ball.

[0014] The first mounting base is provided with two fixing seats, each of which has a through hole, and the two elastic elements are respectively disposed in the two through holes.

[0015] The elastic ball bearing assembly also includes adjusting screws. The two adjusting screws are located on opposite sides of the two elastic elements, and the adjusting screws are threadedly connected to the fixed seat through the threads provided in the through hole.

[0016] The elastic connector also includes a second mounting base, and the clip is disposed on the second mounting base. Both ends of the second mounting base are provided with a fourth mounting hole.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0030] The following is combined with Figure 1-5 The present invention will be described in further detail below.

[0031] Example 1, refer to Figure 1-2 A fireproof cabinet fusible link assembly and a fireproof cabinet, comprising: a fixed plate 1, a flexible female connector, a flexible male connector, and two fusible link assemblies, wherein the flexible female connector and the male connector are elastically inserted into each other; the flexible female connector includes a first mounting base 3; the two fusible link assemblies are respectively placed at both ends of the first mounting base 3, each fusible link assembly including a fusible link 2, one end of which is connected to the fixed plate 1, and the other end is connected to the first mounting base 3. During installation, the fixed plate 1 and the flexible male connector are respectively fixed to the fireproof cabinet body and the door closer connecting rod, thus, the fusible link is fused to the door. The fuse 2 fixes the flexible female end to the fixed plate 1. Under normal use, the flexible female end and the connecting male end are elastically connected to maintain the open state of the fireproof cabinet. In the event of a fire, the high temperature causes the fuse 2 to melt, causing the flexible female end to separate from the fixed plate 1. The open state of the fireproof cabinet can no longer be maintained, and the door closer closes the fireproof cabinet. During production, only the fuse 2 needs to be produced, and then assembled with the fixed plate 1, the flexible female end, and the flexible male end to complete the production and installation of the door closing component. The production process is simple and the production cost is low.

[0032] like Figure 1 and Figure 2 As shown, the fuse assembly specifically includes two fuses 2. One end of each fuse 2 is connected to the first mounting base 3, and the other end of each fuse 2 extends toward both sides of the first mounting base 3. The first mounting base 3 has first mounting holes at both ends, and the fuses 2 have second mounting holes at both ends. The fixing plate 1 has several third mounting holes. Fasteners are provided at both ends of each fuse 2. Two fasteners connect the corresponding second mounting holes and the corresponding third mounting holes. Multiple fuses 2 are connected to the first mounting base 3 from different positions to improve the connection stability. Furthermore, fuses 2 of different thicknesses can be used according to the required fixing strength, or multiple fuses 2 can be stacked together.

[0033] like Figure 1 and Figure 2As shown, to achieve the elastic insertion and engagement of the elastic female connector and the elastic male connector, the elastic female connector further includes two elastic ball assemblies. Each elastic ball assembly includes an elastic element and two balls 4. The two balls 4 are positioned opposite each other on the first mounting base 3 (specifically, the first mounting base 3 has two fixing bases 31, each with a through hole, and two elastic elements are respectively disposed within the two through holes, the elastic elements causing a portion of the balls 4 to be outside the through holes). The two elastic elements are respectively positioned on the side of the two balls 4 that are far apart from each other. The elastic male connector is provided with a locking head 5 and a second mounting base 6. The locking head 5 is positioned... On the second mounting base 6, both ends of the second mounting base 6 are provided with fourth mounting holes. Both sides of the locking head 5 have locking grooves 51 that are adapted to the ball catches 4. The width of the end of the locking head 5 away from the second mounting base 6 is less than or equal to the distance between the two fixed bases 31, but greater than the distance between the two ball catches 4 in the initial state. When the cabinet is opened, during the process of the locking head 5 being inserted between the two fixed bases 31, the two ball catches 4 are pushed into the through holes on both sides. When the locking grooves 51 reach the position of the ball catches 4, the ball catches 4 are acted upon by the elastic element, and the two ball catches 4 are respectively locked in the locking grooves 51 on both sides of the locking head 5, maintaining the open state of the cabinet.

[0034] Further optimizations include, for example Figure 1 and Figure 2 As shown, the elastic ball bearing assembly also includes adjusting screws 7. Two adjusting screws 7 are located on the side of the two elastic elements that are far apart from each other. The adjusting screws 7 are threadedly connected to the fixing seat 31 through the thread provided in the through hole. In this way, by turning the adjusting screws 7 toward the ball bearing 4, the elastic element (which can be a spring) is compressed, and the tension when the adjusting clip 5 disengages from the two ball bearings 4 is adjusted to adapt to different usage environments.

[0035] like Figure 3-Figure 5 As shown, in addition to Embodiment 1, this application also has Embodiment 2, which is an automatic closing fireproof cabinet, including the fireproof cabinet fuse assembly as described above.

[0036] The fireproof cabinet specifically includes a cabinet door (as shown in Figure A), a cabinet body (as shown in Figure B), a first connecting rod 8 of the door closer rotatably mounted on the cabinet door, and a second connecting rod 9 of the door closer rotatably mounted on the cabinet body. The first connecting rod 8 and the second connecting rod 9 of the door closer are rotatably connected. A fixing plate 1 is mounted on the cabinet body, and an elastic connecting end is mounted on the second connecting rod 9 of the door closer. When the cabinet body is in the open state, the elastic connecting end is inserted into the elastic connecting end. A base is provided on the cabinet body (as shown in Figure C). The second connecting rod 9 of the door closer and the fixing plate 1 are both mounted on the cabinet body through the base (the second connecting rod 9 of the door closer is rotatably mounted on the door closer body, and the door closer body is mounted on the base). Thus, when the cabinet body is in the closed state (as shown in Figure B), the door closer is rotatably mounted on the door closer body, and the door closer body is mounted on the base. Figure 3 and Figure 4As shown, the flexible female connector is separated from the male connector. When the cabinet is in the open state, the clip 5 of the male connector is inserted between the two fixed seats 31 of the flexible female connector to maintain the open state of the cabinet door. When the high temperature melts the fuse 2, the flexible female connector is separated from the fixed plate 1 and can no longer maintain the open state of the cabinet door. The cabinet door is automatically closed under the action of the door closer.

[0037] In summary, the fuse 2 serves two purposes: it not only fixes the elastic connection female end, with multiple fuses 2 in different positions jointly connecting the elastic connection female end and the fixing plate 1 to improve the stability of the fixation, but also separates the second connection 9 of the door closer and the cabinet in case of fire, so that the cabinet can close the door in time.

[0038] In this application, both the flexible female end and the connecting male end are precision-cast stainless steel metal structures, which are sturdy, durable, and corrosion-resistant. They contain an elastic structure that allows for adjustable tightness and flexible use. The solid metal spherical contact beads are not easy to rust, are durable, will not experience fatigue failure during insertion, and have a long service life.

[0039] The structure described in this application can also be used in conjunction with a sequencer for gas cylinder cabinets with a door closing sequence.

[0040] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
