[0001] The utility model relates to the technical field of explosion-proof doors, and particularly relates to an explosion-proof door with a self-rescue function. Background Technique

[0002] In modern buildings, such as the entrances and exits of shopping malls, hospitals, warehouses, and parking lots, explosion-proof doors play a crucial role. They are key facilities for personnel safety and maintaining the stability of the internal environment.

[0003] However, the existing explosion-proof doors also have the following disadvantages: In case of an emergency, relying on manual operation to close not only takes a long time but also is prone to operation errors in a tense and chaotic environment. This delay may cause the explosion shock wave or flame to quickly invade the protected area, posing a direct threat to personnel safety and increasing the risk of property loss. Therefore, the lack of an immediate response mechanism makes such explosion-proof doors appear passive and inefficient in dealing with emergencies. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To better understand the technical content of the present utility model, specific embodiments are provided below, and the present utility model will be further described in conjunction with the accompanying drawings.

[0028] See Figures 1 to 6, the controller adopts an STM32 single-chip microcomputer or a SMART200 PLC controller. The present utility model provides an explosion-proof door with a self-rescue function, which includes an explosion-proof door body 1 and a door frame 2 that are hinged to each other. A plurality of insertion grooves 3 and a plurality of insertion holes are respectively provided on the sides of the explosion-proof door body 1 and the door frame 2, and protective strips 4 are provided on the inner walls of the door frame 2; fastening mechanisms and door-pushing mechanisms are respectively provided on both sides of the door frame 2, a control box 5 is provided on the top surface of the door frame 2, and a first sensor 6, a second sensor 7 and a third sensor 8 are provided at the top of the front of the door frame 2. The first sensor 6, the second sensor 7 and the third sensor 8 are all connected to the controller in the control box 5; the fastening mechanism includes a receiving box 9, a fastening component and a first driving source 10 are provided in the receiving box 9, and the output end of the first driving source 10 is used to drive the fastening component to pass through a plurality of insertion holes and connect with a plurality of insertion grooves 3; the door-pushing mechanism includes a driving box 11 and a driving plate 12. The left side of the driving box 11 is communicated with a storage box 13. The driving plate 12 is slidably connected in the driving box 11 and the storage box 13. A second driving source 14 and a pushing component are provided in the driving box 11. The pushing component is connected to the driving plate 12, and the second driving source 14 drives the pushing component to push the driving plate 12 towards the explosion-proof door body 1; wherein, the first driving source 10 and the second driving source 14 are connected and controlled by the controller.

[0029] It should be noted that the door frame 2 is installed in a preset door, and the fastening mechanism on the side of the door frame 2 is arranged in a solid wall and fixed by cement pouring to improve stability. The door-pushing mechanism is arranged on the wall inside the project to facilitate the subsequent pushing of the explosion-proof door body 1 and improve the use efficiency. The first driving source 10 and the second driving source 14 are driving motors of conventional models. The first sensor 6, the second sensor 7 and the third sensor are a pressure sensor, a sound sensor and an infrared sensor respectively.

[0030] In addition, a backup power supply and a switch are arranged outside the driving box 11 and the receiving box 9 for starting the first driving source 10 and the second driving source 14 after the emergency situation ends to drive the fastening component and the pushing component to open the explosion-proof door body 1.

[0031] Specifically, when the first sensor 6, the second sensor 7 and the third sensor 8 detect pressure fluctuations, sound waves or flames at the initial stage of an explosion, they immediately trigger the controller's door-closing instruction. The pushing component in the driving box 11 pushes the driving plate 12 through the second driving source 14. After the right side of the driving plate 12 contacts the explosion-proof door body 1, it starts to push and pushes the explosion-proof door body 1 into the door frame 2. After the explosion-proof door body 1 contacts the protective strip 4, the driving plate 12 stops pushing. At the same time, the explosion-proof door body 1 is tightly limited in the door frame 2. Subsequently, the controller starts the first driving source 10 to drive the fastening component to pass through a plurality of insertion holes and connect with a plurality of insertion grooves 3. The fastening component tightly connects the door frame 2 and the explosion-proof door body 1, so that the explosion-proof door can perform automatic protection in case of emergencies, timely protect the safety of personnel inside the project, and reduce the risk of property.

[0032] Preferably, the protective strip includes a long strip block and a rubber tube strip. One side of the long strip block is adhesively connected to the rubber tube strip, and the other side of the long strip block is fixedly connected to the side wall of the door frame 2.

[0033] The long strip block is used to limit that when the explosion-proof door body 1 is pushed by the driving plate 12, it cannot continue to move forward to the other side of the door frame 2. At the same time, it is convenient for the insertion slot 3 of the explosion-proof door body 1 to align with the insertion hole of the door frame 2, and it is convenient for the pushing fastening component to align and pass through a plurality of insertion holes to be connected with a plurality of insertion slots 3. In addition, when a fire occurs, the rubber tube strip is used to expand and seal the gap between the door frame 2 and the explosion-proof door body 1, improving the protection performance of the explosion-proof door body 1.

[0034] Preferably, the fastening component includes a plurality of bolts 15. The bolts 15 are correspondingly connected to the insertion holes and a plurality of insertion slots 3. One ends of the plurality of bolts 15 are connected by a vertical rod 16. Slide rails are provided on both the inner top surface and the inner bottom surface of the receiving box 9. The top end and the bottom end of the vertical rod 16 are slidably connected to the slide rails. The first driving source 10 is fixed on the side wall of the receiving box 9, and its output end is threadedly connected to the middle part of the vertical rod 16.

[0035] In an example, the controller starts the first driving source 10. The first driving source 10 slides the vertical rod 16 to the right in the guide rail of the receiving box 9, and passes the bolt 15 through the insertion hole to be connected with the insertion slot 3, thereby improving the stability of the explosion-proof door body 1, so that when the explosion-proof door body 1 is impacted by a shock wave, the explosion-proof door body 1 cannot be pushed open, thus protecting the safety of personnel and property inside the project.

[0036] Preferably, the side of the receiving box 9 is closely connected to the side of the door frame 2 through a sealing strip.

[0037] The side of the receiving box 9 is closely connected to the side of the door frame 2 through the sealing strip, preventing carbon dioxide from seeping into the project when a fire occurs.

[0038] Preferably, the pushing component includes a driving wheel 17 and a driving rack 18. The second driving source 14 is built into the driving box 11. The output end of the second driving source 14 is connected to the driving wheel 17. The driving plate 12 is provided with a driving rack 18. The driving rack 18 is meshed with the driving wheel 17. The top surface of the driving plate 12 can slide on the inner top surfaces of the driving box 11 and the storage plate box 13. The driving plate 12 is pushed towards the explosion-proof door body 1 by the driving wheel 17 of the second driving source 14 meshing with the driving rack 18.

[0039] It should be noted that the driving wheel 17 is a gear.

[0040] In one example, the controller drives the second drive source 14, and the second drive source 14 rotates the drive wheel 17. The drive wheel 17 meshes with the drive rack 18 to extend and move the drive plate 12 to the right, so that the drive plate 12 pushes the explosion-proof door body 1 to close and fit within the door frame 2. When the drive wheel 17 meshes with the drive rack 18, the drive strip slides on the inner top surface of the drive, so that the drive plate 12 remains stable during movement.

[0041] It should be noted that when the drive plate 12 is pushed to the middle of the explosion-proof door body 1, the explosion-proof door body 1 is completely closed with the door frame 2. When the drive plate 12 continues to advance and approaches the lock core 22 and then stops, at this time, the drive plate 12 provides a support and protection function for the back of the explosion-proof door body 1. It should be noted that the extended length of the drive plate 12 is based on the preset drive of the controller. When the drive plate 12 stops extending, the drive rack 18, the drive box 11, and the storage plate box 13 are all in a horizontal straight state, and due to its own gravity, the drive rack 18 cannot easily push the drive plate 12 away without external force.

[0042] Preferably, a rolling part is provided at the right end of the drive plate 12, and the rolling part is in contact and slides with one side of the drive plate 12. The rolling part includes a roller 19 and a fixing piece 20. Fixing pieces 20 are provided on both the upper and lower surfaces at the right end of the drive plate 12, and the two fixing pieces 20 are connected by a roller 19.

[0043] It should be noted that when using the roller 19 to contact and push the explosion-proof door body 1, the friction is reduced, making it easier for the drive plate 12 to advance.

[0044] In one example, when the drive plate 12 extends to the right and the roller 19 contacts the explosion-proof door body 1, it rotates between the fixing pieces 20, so that when the roller 19 pushes the explosion-proof door body 1, it rotates and pushes, reducing the friction.

[0045] Preferably, a rotating member 21 is provided on one side of the explosion-proof door body 1, and the rotating member 21 is connected to a lock core 22 provided on the other side of the explosion-proof door body 1.

[0046] It should be noted that the rotating member 21 is as Figure 1 shown. In the normal state, the explosion-proof door body 1 can be opened by twisting the rotating member 21 to unlock the lock core 22. In the normal state, the controller locks the fastening mechanism and the door-pushing mechanism so that they do not perform work, preventing excessive use and increasing the door opening and closing procedures. The connection and use function of the rotating member 21 and the lock core 22 are prior art, and their working principles will not be elaborated here.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
