Detailed description of the invention
As Figure 1-3, described fire escape list fan closed guard gate is without threshold list fan wicket, primarily of five part compositions: doorframe 2, door leaf 1, locking 3, hinge page 4 and sealed bottom mechanism 5.
Described doorframe 2 is bearings of door leaf 1, is embedded in door frame wall, is welded by angle steel, it has obturator hernia, and angle steel surface soldered has adhesive tape groove, and sealing joint strip is arranged in adhesive tape groove; Described door leaf 1 is the parts for wave that mainly withstands shocks, and is formed by shaped steel and Plate Welding, facilitates the movement of persons when door leaf 1 is opened, when door leaf 1 cuts out, and press seal bar, inside and outside isolated, play airtight effect.
The effect of described locking 3 is that locking head is inserted in doorframe lockhole, and door leaf 1, progressively near doorframe 2, is finally adjacent to doorframe press seal bar; Described hinge page 4 is supports that door leaf 1 rotates, and can make door leaf 1 flexible rotating and make it to doorframe 2 direction translation.
After door leaf 1 cuts out, door leaf 1 and the upper, left and right of doorframe 2 all achieve sealing, but this door does not have threshold, and also will realize between door leaf 1 and ground sealing, sealing is herein realized by sealed bottom mechanism 5.
As Figure 4-Figure 6, described sealed bottom mechanism 5 is made up of reducer 33, sealed beam 8, drive link 34, connecting axle 16, splicing sleeve 19, pivoted arm 21, pivoted arm 21, weather strip 22 etc.All being provided with drive link 34 at two ends, declining for promoting weather strip 22.
In Fig. 5, reducer 33 is connected on reducer Connection Block 31 by bolt 32, and reducer Connection Block 31 and door leaf are welded into entirety, and reducer 33 power shaft is provided with rocking handle 11, and the sealing of power shaft and door leaf is ensured by seal cover board 10 and O RunddichtringO 9.
In Fig. 4, described reducer 33 output shaft connects splicing sleeve 19 by flat key 17, and the other end of splicing sleeve 19 is also connect connecting axle 16 by flat key 18.In Fig. 6, the other end of connecting axle 16 is supported on pivoted arm seat 20, and axially located by circlip for shaft 23, pivoted arm seat 20 is weldingly fixed on door leaf, and connecting axle 16 connects pivoted arm 21 by flat key 18.
In Fig. 4, drive link 34 upper end is connected with pivoted arm 21 by screw thread, lock with round nut 15 after adjusting position, drive link 34 lower end is connected with connecting hinge ear 12 by bearing pin 13, and connecting hinge ear 12 is welded on sealed beam 8, bearing pin 13 can rotate in connecting hinge ear 12 hole, for preventing bearing pin 13 from coming off, in bearing pin 13 one end, cottor pin 14 is housed, guard shield 35 is connected on junction plate 6 by bolt 7, junction plate 6 and sealed beam 8 weld together, and weather strip 22 is contained in the adhesive tape groove bottom sealed beam 8.
When described fire escape list fan closed guard gate closes: pull on door leaf 1 and shake hands, door leaf 1 rotates around hinge page 4, after door leaf 1 contacts with doorframe 2, rotate latch handle locking head and insert doorframe obturator hernia, door leaf 1 press seal bar, rotate sealed bottom rocking handle 11 according to switch mark, drive sealed beam 8 to move downward, weather strip 22 compresses the closedown that ground realizes having sealed door; When door is opened: first rotate sealed bottom rocking handle 11 according to the instruction of switch mark, after sealed beam 8 rising puts in place, rotate latch handle and door leaf 1 is opened, pull door leaf to shake hands door to be opened to assigned position.
