[0002] Computer servers are installed in the server room. Since the server emits a lot of heat when working, cooling and heat dissipation in the server is particularly important. The server room is usually equipped with air conditioners to reduce the temperature of the server room and ensure the normal operation of the server. If the cooling device of the server is damaged or the air conditioner in the server room is damaged, resulting in continuous high temperature in the server room, not only the server is prone to failure, but other equipment in the server room will also run unstably, and in serious cases, it may induce a fire in the server room.

[0003] When a fire breaks out in the server room, the indoor temperature quickly rises to 600-700℃, or even over 1000℃. At such high temperatures, people inside cannot open the door lock by hand when escaping. At the same time, the lock core will deform and get stuck due to the high temperature, thus affecting the escape of people inside. Utility Model Content

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 to Figure 3As shown, the right end of the fire porch 100 of the utility model is connected to the server room 200 through the inner fire door 1, and the left end of the double fire porch 100 is connected to the outside through the outer fire door 2. Such a structure can effectively prevent the outdoor fresh air flow from entering the server room 200 to increase the risk of fire. The inner fire door 1 and the outer fire door 2 have the same structure, respectively including a door frame 11 and a door panel 12. Figure 3 The left side of the middle door panel 12 is hinged to the left side of the door frame 11 through three hinges 13 , and the lower left side of the door panel 12 is locked with the lower left side of the door frame 11 through a foot-operated door latch device 3 .

[0023] like Figure 2 to Figure 5 As shown, the foot-operated door latch device 3 is symmetrically arranged on the inner fire door 1 and the outer fire door 2, and includes a rotating shaft 31, an inner pedal 32, an outer pedal 33, a latch plate 34, a locking seat 35, an upper fixing block 36, a lower fixing block 37 and a tension spring 38. The middle part of the rotating shaft 31 is hinged to the lower part of the other side of the door panel 12, and both ends of the rotating shaft 31 are positioned on the lower part of the other side of the door panel 12 through a retaining ring 311. The inner pedal 32 of the inner fire door 1 is located on the side of the door panel 12 facing the server room 100, and the inner pedal 32 of the outer fire door 2 is located on the side of the door panel 12 away from the double fire porch 100. The outer pedal 33 of the inner fire door 1 and the outer pedal 33 of the outer fire door 2 are respectively facing the double fire porch 100, and the inner pedal 32 and the outer pedal 33 are arranged in parallel.

[0024] like Figure 4 and Figure 5 As shown, the left end of the latch plate 34 is welded and fixed to the end of the outer pedal 33 near the rotating shaft 31, and the right end of the locking seat 35 is welded and fixed to the lower part of the other side of the door frame 11, and is perpendicular to the latch plate 34. The upper fixing block 36 is welded and fixed to the middle part of one side of the latch plate 34, and the lower fixing block 37 is located at the lower side of the upper fixing block 36 and welded and fixed to the lower part of the other side of the door panel 12. Tension spring hooks 381 are respectively installed on the lower side of the upper fixing block 36 and the upper side of the lower fixing block 37, and the two ends of the tension spring 38 are respectively hooked on the upper and lower tension spring hooks 381, so that the end of the latch plate 34 is clamped in the locking seat 35, thereby locking the door panel 12 in a closed state.

[0025] like Figure 4 As shown, the locking seat 35 is in a transverse T-shape, and the vertical plate 351 of the transverse T-shape is fixed on the lower part of one side of the door frame. A positioning notch 353 is provided at the intersection of the horizontal plate 352 of the transverse T-shape and the vertical plate 351. The width of the positioning notch 353 matches the thickness of the latch plate 34, so that the locked door panel 12 will not shake. The left end of the horizontal plate 352 facing away from the vertical plate 351 is provided with an angle, so that the right end of the latch plate 34 rises along the angle and falls into the positioning notch 353 to lock the door panel 12.

[0026] like Figure 5As shown, square pin rods 321 are extended from the adjacent ends of the inner pedal 32 and the rotating shaft 31, and from the adjacent ends of the outer pedal 33 and the rotating shaft 31 respectively. The square pin rods 321 are perpendicular to the corresponding inner pedal 32 or outer pedal 33 respectively. The square pin rods 321 are respectively extended into the square positioning pin holes 312 of the corresponding ends of the rotating shaft 31, and are respectively vertically connected to the corresponding ends of the rotating shaft 31 through set screws 313.

[0027] Positioning ribs 322 are respectively provided on both sides of the inner pedal 32 and the outer pedal 33, and a plurality of convex anti-slip strips 323 are respectively provided on the upper bottom surface of the inner pedal 32 and the upper bottom surface of the outer pedal 33. When the escapee steps on the inner pedal 32 or the outer pedal 33, the positioning ribs 322 limit the two sides of his feet to prevent the feet from slipping off. The plurality of convex anti-slip strips 323 can increase the friction between the sole of the escapee's shoe and the outer pedal 42 or the inner pedal 43, ensuring that the latch plate 34 can be immediately unlocked by stepping on it, thereby accelerating the escape of the escapee.

[0028] like Figure 6 As shown, the sealing mechanism 4 includes a sealing groove 121 and an elastic sealing strip 41. The sealing groove 121 with a rectangular cross section is close to the door panel limiting edge 111 on the door frame 11 and surrounds the door panel 12. The elastic sealing strip 41 is embedded in the sealing groove 121. When the door panel 12 is closed, the outer edge of the elastic sealing strip 41 abuts against the inner peripheral surface of the door frame 11. The elastic sealing strip 41 effectively seals the server room 200 to prevent the toxic gas generated in the event of a sudden fire from entering the fire vestibule 100, thereby ensuring the safety of the escapees who have entered the fire vestibule 100.

[0029] When a fire breaks out in the server room 200 and the people inside need to escape, the escapee quickly reaches the front side of the inner fire door 1 and immediately steps on the inner pedal 32 of the inner fire door 2. The outer pedal 33 drives the latch plate 34 to overcome the tension of the tension spring 38 and rotate to disengage the positioning notch 353 of the locking seat 35. The inner fire door 2 is unlocked and can be kicked open. After the escapee quickly enters the double fire door porch 100, he steps on the outer pedal 33 of the inner fire door 2 while closing the inner fire door 2. The latch plate 34 rises along the horizontal plate 352 of the locking seat 3 at an angle and falls into the locking door plate 12 in the positioning notch 353. The inner fire door 2 is then closed and locked, effectively preventing the toxic gas generated by the fire in the server room 200 from overflowing into the double fire door porch 100, and ensuring the safety of the escapee in the double fire door porch 100. After the escapee quickly reaches the outer fire door 1 at the outer end of the double fire porch 100, the same action procedure as the aforementioned opening of the inner fire door 2 can be used to quickly open the outer fire door 1 and quickly escape to the outdoors.

[0030] In addition to the above-mentioned embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
