It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of slide rail type people's air defense door provided by the utility model;
Fig. 2 is the top view of slide rail type people's air defense door provided by the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Such as Fig. 1 and Fig. 2, slide rail type people's air defense door of the present utility model, including metal door frame 1, door leaf 2 and breech-block
Structure, metal door frame 1 and door leaf 2 pass through blocking mechanism locking positioning.
The top of metal door frame 1 is provided with upper rail 11 close to the side of door leaf 2, and the bottom of metal door frame 1 is close to the side of door leaf 2
Provided with lower railway 12, ball grooves are additionally provided with lower railway 12, multiple balls are provided with ball grooves.Door leaf 2 includes the interior He of door leaf 21
External door leaf 22, cushion 23 is provided between interior door leaf 21 and external door leaf 22, and by the mechanism connection that is slidably connected, cushion 23 is bullet
Spring component or foamed aluminium, the mechanism that is slidably connected include pulley 24 and slideway 25, and pulley 24 is arranged on interior door leaf 21, and slideway 25 is set
Put on the first groove of external door leaf 22, when external door leaf 22 is impacted, cushion 23 can be extruded, so as to which inside door leaf 21 is transported
It is dynamic, significantly reduce the impulsive force that interior door leaf 21 is subject to.Four sides of interior door leaf 21 are provided with anticollision sealant layer 4, and top is provided with can
The upper rail chute 211 of upper rail 11 is encased, bottom is provided with the lower railway chute 212 that can encase lower railway 12, anticollision fluid sealant
Four sides that layer 4 wraps interior door leaf 21, the inside of anticollision sealant layer 4 are provided with magnet 41, the right and left of metal door frame 1 provided with
The second groove 13 that magnet 41 agrees with.Anticollision sealant layer 4 is double-deck glue-line, and short glass fiber layer is provided with double-deck glue-line, and increase is anti-
Hit the service life of sealant layer 4.
Side of the external door leaf 22 away from interior door leaf 21 is arcuate structure 221, the power for making to be hit and the area minimum that is hit
Change.The inside of external door leaf 22 has the steel-structured circular cylinder 222 above and below multiple insertions, and multiple surfaces of steel-structured circular cylinder 222 are each other
It is tangent, the weight of external door leaf 22 is alleviated, while do not weaken the impact resistance of external door leaf 22.
Blocking mechanism is link type locking, including tapered end 31, upper latch receptacles 32 and lower latch receptacles 33 and rack-and-pinion it is closed
Box 34, tapered end 31 are arranged in interior door leaf 21, and lower upwards respectively from rack-and-pinion closed enclosure 34 to extend, upper latch receptacles 32 are with
Latch receptacles 33 are respectively arranged on the inside of the top of metal door frame 1 and on the inside of lower section.
Space between interior door leaf 21 and external door leaf 22 is provided with sealing joint strip 5, prevent extraneous dust enter interior door leaf 21 with
Between external door leaf 22, the smooth of pulley 24 and slideway 25 is kept.Sealing joint strip 5 is double-decker, and centre is provided with space, is reserved
The space of sealing strip compressional deformation, sealing strip is avoided to cause the situation of damage and sealing decline because of sex.
When closing door leaf 2, the magnet 41 in anti-collision rubber layer is embedded into the second groove 13 of metal door frame 1, make gold
Together with category doorframe 1 is preferably closed with door leaf 2, blocking mechanism is then shaken, metal door frame 1 and door leaf 2 are locked.When by
During impulsive force, external door leaf 22 can extrude cushion 23, move so as to inside door leaf 21, and significantly reduce that interior door leaf 21 is subject to rushes
Power is hit, protects interior door leaf 21.
In summary, slide rail type people's air defense door of the present utility model effectively improves the sealing of metal door frame and door leaf,
The weight of door leaf is alleviated, facilitates slip and the switch of door leaf, while also enhances its shock resistance, further prevents inside door
The breakage of fan.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
