[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel fireproof and watertight door with a protective structure, comprising: a mounting frame, and an inner door panel disposed on the right side of the mounting frame, an outer door panel disposed on the left side of the mounting frame, and a door frame connected to the right side of the outer door panel;

[0008] Also includes:

[0009] The first positioning block is installed inside the mounting frame, and the inner side of the first positioning block is connected to the first support frame. The inner side of the first support frame is provided with fireproof filler. The upper side of the inner door panel is provided with the first positioning ring, and the upper side of the outer door panel is provided with the second positioning ring. The right side of the second positioning ring is connected to the light-transmitting component, and the outer side of the mounting frame is the limiting component.

[0010] The third support frame is installed inside the outer door panel, and a second positioning block is connected to the right side of the third support frame. A second limiting rod passes through the outer side of the third support frame, and a first reinforcing rod is provided inside the third support frame. A second reinforcing rod is provided in the middle of the first reinforcing rod. A Kevlar protective plate is provided on the left side of the third support frame, and a third positioning block is provided on the outer side of the outer door panel. A fireproof sealing ring is connected to the right side of the third positioning block.

[0011] In one possible implementation, the first support frame is slidably connected to the first positioning block, and the first positioning block is symmetrically arranged about the central axis of the first support frame.

[0012] In one possible scenario, the third support frame is engaged with the outer door panel, and the second limiting rod is threadedly connected to both the third support frame and the outer door panel.

[0013] In one possible scenario, the third support frame is slidably connected to the second positioning block, and the longitudinal section of the second positioning block is a "T" shaped structure.

[0014] In one possible scenario, the first and second reinforcing rods are arranged at equal intervals inside the third support frame.

[0015] In one possible scenario, the fireproof sealing ring is engaged with the third positioning block, and the third positioning block is symmetrically arranged about the central axis of the outer door panel.

[0016] In one possible implementation, the light-transmitting component includes a second support frame mounted on the right side of the second positioning ring, and a light-transmitting plate is provided inside the second support frame, and a first limiting rod is provided on the right side of the second support frame;

[0017] The longitudinal section of the second support frame is a circular structure, and the first limiting rod is threadedly connected to the second support frame and the second positioning ring.

[0018] In one possible implementation, the limiting assembly includes a locking plate mounted on the outside of the mounting bracket, with a third limiting rod passing through the center of the locking plate;

[0019] The locking plate is engaged with both the inner and outer door panels, and the locking plate is symmetrically arranged about the central axis of the mounting bracket.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This steel fireproof and watertight door with a protective structure has an effective protective support structure inside the device, making it less likely to break or deform immediately when subjected to external impact, thus avoiding affecting the safety of the device and improving its strength. At the same time, it facilitates quick disassembly and recycling after use, allowing operators to easily replace and repair damaged parts, improving maintenance efficiency and resulting in better performance. Specifically, as shown below:

[0021] 1. The third support frame is fixed inside the outer door panel by the second positioning block and the second limiting rod. The first and second reinforcing rods inside the third support frame provide double reinforcement for the third support frame and the outer door panel. At the same time, the Kevlar protective plate reinforces and protects the left side surface of the third support frame, preventing the device from being damaged immediately due to collision during use and improving the strength of the device.

[0022] 2. The second support frame and the light-transmitting plate are fixed to the upper side of the inner and outer door panels by the second positioning ring and the first limiting rod. This allows the operator to easily observe and connect the disaster situation on the other side of the device through the light-transmitting plate set inside the second support frame, avoiding the rash operation of the first positioning ring to rotate and open the device without knowing the situation, thus improving the efficiency of the device.

[0023] 3. By rotating the third limit rod, the outward rotation of the third limit rod releases the series limit on the locking plate and the mounting bracket, which facilitates the operator to quickly disassemble the device and quickly replace and repair damaged parts inside the device, thereby improving the maintenance efficiency of the device and reducing the labor intensity of the operator.

[0030] 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.

[0031] Please see Figure 1-4 This utility model provides a technical solution: a steel fireproof and watertight door with a protective structure, including a mounting frame 1, a first positioning block 2, a first support frame 3, fireproof filler 4, an inner door panel 5, a door lock 6, a first positioning ring 7, an outer door panel 8, a second positioning ring 9, a second support frame 10, a light-transmitting plate 11, a first limiting rod 12, a third support frame 13, a second positioning block 14, a second limiting rod 15, a first reinforcing rod 16, a second reinforcing rod 17, a Kevlar protective plate 18, a locking plate 19, a third limiting rod 20, a third positioning block 21, a fireproof sealing ring 22, and a door frame 23.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, before using the device, the engaging connection between the third support frame 13 and the outer door panel 8 allows the operator to easily install the third support frame 13 inside the outer door panel 8. The sliding connection between the second positioning block 14 and the third support frame 13 guides and positions the third support frame 13 as it is installed into the outer door panel 8 to the right, preventing positional displacement during installation. At this time, rotating the second limiting rod 15 that passes through the outer side of the third support frame 13 further facilitates the installation. The threaded connection between the second limiting rod 15, the third support frame 13, and the outer door panel 8 ensures that... The second limiting rod 15, which rotates to the right, can effectively reduce the connection between the third support frame 13 and the outer door panel 8. At this time, the first reinforcing rod 16 and the second reinforcing rod 17, which are equally spaced inside the third support frame 13, provide double reinforcement for the third support frame 13 and the outer door panel 8, making it less likely for the third support frame 13 and the outer door panel 8 to suffer large-area dents and damage when hit by external objects. The Kevlar protective plate 18 installed inside the left side of the third support frame 13 has strong flame-retardant properties, making the third support frame 13 less likely to be damaged by combustion during use. At the same time, the third support frame 13 is less likely to be damaged by fire during use. The internal Kevlar protective plate 18 effectively provides strong structural strength, improves the strength of the third support frame 13, further enhances the flame-retardant reinforcement effect of the outer door panel 8 and the third support frame 13, and improves the overall performance of the device. Simultaneously, after completing the installation of the third support frame 13, the engaging connection between the second support frame 10 and the second positioning ring 9 allows the operator to easily install the second support frame 10 on the right side of the second positioning ring 9. At this point, rotating the first limiting rod 12 on the right side of the second support frame 10, and due to the screw connection between the first limiting rod 12 and the second support frame 10 and the second positioning ring 9... The textured connection structure allows the first limiting rod 12, which rotates to the left, to effectively fix the second support frame 10 and the light-transmitting plate 11 to the upper side of the inner door panel 5 and the outer door panel 8. At this time, due to the light transmittance of the light-transmitting plate 11, personnel on both sides of the device can easily observe the space on both sides of the device through the first limiting rod 12. This facilitates the observation and connection of personnel on the other side of the device in case of special circumstances such as fire on one side of the device, by using the light-transmitting plate 11 set inside the second support frame 10. This avoids the risk of unknowingly operating the door lock 6 to rotate along the door frame 23 to open the device, thus improving the efficiency of the device.

[0033] Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, after the device is used, by rotating the third limiting rod 20 that passes through the middle of the locking plate 19, the threaded connection between the third limiting rod 20 and the locking plate 19 and the mounting bracket 1 causes the third limiting rod 20, which rotates outward, to loosen its connection with the locking plate 19 and the mounting bracket 1. This makes it easier for the operator to pull out the locking plate 19. At this time, because of the engaging connection between the locking plate 19 and the inner door panel 5 and the outer door panel 8, the locking plate 19, which has moved outward, loosens its engaging connection with the inner door panel 5 and the outer door panel 8. This makes it easier for the operator to pull out the inner door panel 5, the first positioning ring 7, and the outer door panel 8. The sliding connection structure between the support frame 3 and the first positioning block 2 facilitates the operator to pull the first support frame 3 to the right and remove it. This allows the operator to easily fill or replace the fireproof filling material 4 inside the first support frame 3. At the same time, pulling the fireproof sealing ring 22 to the right causes the fireproof sealing ring 22 to disengage from the third positioning block 21 due to the engaging connection structure between the third positioning block 21 and the fireproof sealing ring 22. This allows for quick disassembly and assembly of the device, facilitating the operator to quickly replace and repair damaged parts inside the device, improving the efficiency of device maintenance and reducing the labor intensity of the operator.
