[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a staggered assembled steel explosion-proof door with good safety performance, including a ground 1 and two steel door panels 5, the left and right sides of the top wall of the ground 1 are fixedly connected with the wall 3, the middle part of the top wall of the ground 1 and the middle part of the inner top wall of the wall 3 are provided with a plurality of locking grooves 4, the inner walls of the two steel door panels 5 are provided with a rotating groove 6, the middle part of the inner wall of the two rotating grooves 6 are rotatably connected with an elliptical rotating block 9, the front sides of the two elliptical rotating blocks 9 are fixedly connected with a rotating valve 10, the upper and lower ends of the outer walls of the two elliptical rotating blocks 9 are meshed and connected with a cross bar 7, the side away from the plurality of cross bars 7 are fixedly connected with a plurality of locking columns 8, the upper plurality of locking columns 8 are snap-connected with the upper plurality of locking grooves 4, the lower plurality of locking columns 8 are snap-connected with the lower plurality of locking grooves 4, and the left and right sides of the inner wall of the wall 3 are provided with a sliding mechanism 2;
[0031] Specifically, under normal circumstances, the two steel door panels 5 are connected to the cross bar 7 through the elliptical rotating block 9 in the rotating groove 6. A rotating valve 10 is installed on the front side of the elliptical rotating block 9, so that the user can drive the elliptical rotating block 9 to rotate in the rotating groove 6 by operating the rotating valve 10. When the elliptical rotating block 9 rotates, the non-convex part on its outer wall will tighten the cross bar 7 and the multiple locking columns 8 connected to it, and move them inward. When the user needs to close the explosion-proof door, by operating the rotating valve 10, the convex part of the elliptical rotating block 9 is connected to the cross bar 7, thereby driving the cross bar 7 and the locking column 8 to move outward. When the locking column 8 moves to a position aligned with the locking groove 4, the locking column 8 will be stuck in the locking groove 4, thereby realizing the firm locking of the steel door panel 5 with the ground 1 and the wall 3. This design ensures that the door panel will not be easily opened or deformed when subjected to impact or explosion pressure, enhances the sealing and safety of the explosion-proof door, and thus protects people's lives and property.
[0032] Reference Figure 2 and Figure 3 The sliding mechanism 2 includes two hidden grooves 201 in the wall, the front and rear sides of the top wall of the floor 1 are both provided with sliding grooves 202, the front and rear ends of the inner wall of the wall 3 are both fixedly connected with fixed frames 203, the front and rear sides of the two steel door panels 5 are both fixedly connected with sliding door panels 204, the bottom walls of the plurality of sliding door panels 204 are all rotatably connected with sliding shafts 205, and the outer walls of the plurality of sliding shafts 205 are slidably connected with the inner bottom walls of the two sliding grooves 202;
[0033] Specifically, a hidden groove 201 is opened in the wall, and a sliding groove 202 is opened in the ground 1, which provides space for the hiding and sliding of the steel door panel 5. When the door panel needs to be opened or closed, they can be moved horizontally through the sliding mechanism 2. Sliding door panels 204 are fixed on the front and rear sides of the steel door panel 5. The sliding door panel 204 is connected to the sliding groove 202 of the ground 1 through a sliding shaft 205, so that the door panel can be easily opened and closed under the guidance of the sliding groove 202. At the same time, the close fit between the sliding door panel 204 and the sliding groove 202 ensures the stability and sealing of the door panel during the sliding process. In addition, the fixed frame 203 provides support and positioning for the door panel. When the door panel is fully closed, it can fit tightly with the fixed frame 203 to form a complete protective barrier, which not only enhances the explosion-proof performance of the door panel, but also improves its overall stability and reliability. In emergency situations such as explosions, it can effectively resist the invasion of shock waves and debris to protect the safety of people and equipment inside the building.
[0034] Reference Figure 1 and Figure 2 A front wall thermometer 11 is fixedly connected to the left end of the front side of the wall 3, and a rear wall thermometer 12 is fixedly connected to the middle of the front side of the wall 3; handles 13 are fixedly connected to the front sides of the two front sliding door panels 204; rubber sealing strips 14 are fixedly connected to the adjacent sides of the two steel door panels 5 and the distant adjacent sides of the two steel door panels 5;
[0035] Specifically, the front wall thermometer 11 and the rear wall thermometer 12 are used to monitor the temperature of the wall 3 in real time, and the temperature changes on the rear and front sides of the explosion-proof door can be checked after the explosion. The handle 13 on the sliding door panel 204 allows the user to easily open or close the sliding door, so that trapped people can be evacuated conveniently and quickly in an emergency. The rubber sealing strip 14 provides good sealing performance, which helps prevent the pressure, shock wave, flame or toxic gas generated by the explosion from leaking through the door gap, thereby protecting people and equipment inside the building.
[0036] Reference Figure 2 and Figure 3 The inner top wall of the wall 3 is fixedly connected with a support beam 15, and the support beam 15 is made of solid steel; the middle part of the inner bottom wall of the two sliding grooves 202 is fixedly connected with a limit block 16, and the two limit blocks 16 are made of rubber; the two steel door panels 5 and the multiple sliding door panels 204 are integrally formed by a die-casting process;
[0037] Specifically, the solid steel support beam 15 provides a strong supporting force for the entire door body, ensuring the stability and structural integrity of the explosion-proof door when subjected to impact. The rubber limit block 16 can limit the sliding range of the sliding door panel 204, ensuring that the door panel will not deviate from the track or move accidentally during movement. The steel door panel 5 and the sliding door panel 204 adopt an integrated die-casting process, which can ensure that the door panel has a high structural strength and integrity, thereby providing strong impact resistance.
[0038] Working principle: Under normal circumstances, the two steel door panels 5 are connected to the cross bar 7 through the elliptical rotating block 9 in the rotating groove 6. A rotating valve 10 is installed on the front side of the elliptical rotating block 9, so that the user can drive the elliptical rotating block 9 to rotate in the rotating groove 6 by operating the rotating valve 10. When the elliptical rotating block 9 rotates, the non-raised part on its outer wall will tighten the cross bar 7 and the multiple locking columns 8 connected to it, and move them inward. When the user needs to close the explosion-proof door, the raised part of the elliptical rotating block 9 is connected to the cross bar 7 by operating the rotating valve 10, thereby driving the cross bar 7 and the locking column 8 to move outward. When the locking column 8 moves to a position aligned with the locking groove 4, the locking column 8 will be stuck in the locking groove 4, thereby realizing the firm locking of the steel door panel 5 with the ground 1 and the wall 3.
[0039] In addition, a hidden groove 201 is opened in the wall, and a sliding groove 202 is opened in the ground 1, which provides space for hiding and sliding of the steel door panel 5. When the door panel needs to be opened or closed, they can be moved horizontally through the sliding mechanism 2. Sliding door panels 204 are fixed on the front and rear sides of the steel door panel 5. The sliding door panel 204 is connected to the sliding groove 202 of the ground 1 through a sliding shaft 205, so that the door panel can be easily opened and closed under the guidance of the sliding groove 202. At the same time, the close fit between the sliding door panel 204 and the sliding groove 202 ensures the stability and sealing of the door panel during the sliding process. In addition, the fixed frame 203 provides support and positioning for the door panel. When the door panel is fully closed, it can fit tightly with the fixed frame 203 to form a complete protective barrier.
