The utility model adopts the following technical solution:
A kind of closed guard gate, including door leaf and doorframe, a side of the door leaf and the doorframe are articulated and connected, the doorframe
Using bearing plate and the one-time formed hot rolling YH people's air defense fashioned iron of oblique band steel, the periphery of the door leaf is equipped with sealing rubber ring, institute in one week
Stating door leaf includes outer layer door leaf and internal layer door leaf, and an interlayer, the folder are formed between the outer layer door leaf and the internal layer door leaf
Annular protrusion is equipped in layer, the annular protrusion is connect with the sealing rubber ring, and the doorframe is equipped with and the annular protrusion
The compatible card slot of shape, the annular protrusion are arranged between the sealing rubber ring, and bottom is connected with pull rod, the pull rod
It can be slided in the interlayer, spring is equipped between the pull rod and the annular protrusion, the outer layer door leaf, which is equipped with, to be fixed
Plate, the fixed plate are equipped with the first sealing elastic slice and the second sealing elastic slice, the first sealing elastic slice and second sealing
There are gap, the ends of the pull rod to be equipped with handle for elastic slice, and the handle stretches out in the gap.
Preferably, sliding chamber is equipped in the interlayer, the outer wall of the sliding chamber and institute intracavitary in the cunning is arranged in the pull rod
It states between interlayer filled with aluminum honeycomb panel.
The utility model has the following beneficial effects: annular protrusion is arranged in the utility model on the door leaf of closed guard gate, and
And connect it with doorframe, the sealing performance of closed guard gate is increased, while being also provided with the structure of the double-deck door leaf, improves door leaf
Structural strength, and doorframe use hot rolling YH people's air defense fashioned iron, eliminate the welding procedure of bearing plate, oblique band steel, especially pressure-bearing
The oblique band steel of plate and angle steel main body single hot-roll forming, the bonding strength between bearing plate and angle steel are improved than the intensity of welding procedure
20 times or more, closed guard gate's protective seal performance is substantially increased, artificial consumptive material substantially drops when making people's air defense door frame main body
It is low；Due to substantially reducing weld length, the internal stress effect generated in doorframe production process is avoided, the change of doorframe is reduced
Shape amount improves the airtightness of closed guard gate, reduces the flue dust and welding slag generated in welding process, keeps production environment cleaner
Only, reduce soot emissions and cause environment pollution.

Specific embodiment
It as shown in Figs. 1-2, is a kind of closed guard gate of the utility model, including door leaf and doorframe 1, a side and door of door leaf
Frame 1 is articulated and connected, and the periphery of door leaf is equipped with sealing rubber ring 2 in one week, and door leaf includes outer layer door leaf 3 and internal layer door leaf 4, outer layer door leaf
An interlayer 5 is formed between 3 and internal layer door leaf 4, is equipped with annular protrusion 6 in interlayer 5, annular protrusion 6 is connect with sealing rubber ring 2, door
Frame 1 is equipped with card slot 7 compatible with 6 shape of annular protrusion, and annular protrusion 6 is arranged between sealing rubber ring 2, bottom connection
There is pull rod 8, pull rod 8 can slide in interlayer 5, and spring 9 is equipped between pull rod 8 and annular protrusion 6, and outer layer door leaf 3 is equipped with solid
Fixed board 10, fixed plate 10 are equipped with the first sealing elastic slice 11 and the second sealing elastic slice 12, the first sealing elastic slice 11 and the second sealing
There are gap, the ends of pull rod 8 to be equipped with handle 13 for elastic slice 12, and handle 13 stretches out in gap.
Sliding chamber 14 is equipped in interlayer 5, the setting of pull rod 8 is filled with aluminium between the outer wall and interlayer 5 of sliding chamber 14 in sliding chamber 14
Cellular board 15, improves the structural strength of door leaf, and enhances soundproof effect.
Specifically, pulling two handles 13, handle 13 drives pull rod 8 in the intracavitary movement of cunning, 6 compressed spring 9 of annular protrusion
And sealing rubber ring 2 is formed with the card slot 7 in doorframe 1 and is tightly connected when annular protrusion 6 is put in doorframe 1, sealing rubber ring 2
It is externally formed with first of sealing, annular protrusion 6 forms second sealing, increases the leakproofness between door leaf and doorframe 1.This
Outside, such as Fig. 3-4, traditional angle steel 17 welds that 1 process of doorframe is more, and time-consuming high, weld seam is long, and consumables cost is high, explosion-proof shock wave, close
Closing property is lower, and the doorframe 1 of the utility model uses hot rolling YH people's air defense fashioned iron, eliminates the oblique band steel welding procedure of bearing plate, especially
It is the oblique band steel 18 of bearing plate 16 with 17 main body single hot-roll forming of angle steel, the connection between the oblique band steel 18 of bearing plate 16 and angle steel 17
Intensity improves 20 times or more than the intensity of welding procedure, substantially increases closed guard gate's shock resistance wave power and protective seal performance,
Artificial consumptive material is greatly reduced when making people's air defense door frame main body；Due to substantially reducing weld length, doorframe production is avoided
