Embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
Shown in 1~Fig. 4 of reference picture, the air-drop type gravity type with buffering efficiency in one embodiment provided by the invention
Air bag, including buffer air bag and bottom plate 9, the lower end of buffer air bag are fixedly connected with bottom plate 9, and the bottom of buffer air bag is provided with air inlet
Mouthfuls 3, bottom plate 9 is provided with through hole, and the through hole on bottom plate 9 docks with the air inlet 3 of buffer air bag, the upper end surrounding cloth of buffer air bag
Provided with sling 1 or hook, for being connected with the bottom of air-drop equipment, there is no gas before air-drop in buffer air bag；Buffered before air-drop
Bag stacking is on bottom plate 9, and the upper end of buffer air bag is connected by sling 1 or hook with air-drop equipment bottom, bottom plate 9 after air-drop
Buffer air bag is pulled open by conducting oneself with dignity, air is poured into buffer air bag in dropping process, and buffer air bag is strutted, when air-drop fills
During standby landing, bottom plate 9 is first landed, and air inlet 3 is blocked, and ensures that the gas in buffer air bag will not be run out of, and buffer air bag is sky
Throw equipment and play cushioning effect, air is filled with by falling mode certainly, buffering effect can be adjusted, the other inflation of carrying can not had to and set
It is standby to be inflated, it is simple in construction, it is easy to operate, the air-drop equipment of various different weights is can be applied to, is also applied for various differences
Height above sea level, upland plain is general.
Further, buffer air bag is provided with the lateral exhaust outlet with hasp.
Further, buffer air bag includes main capsule 2 and auxiliary capsule 4, and auxiliary capsule 4 is arranged at the side of main capsule 2, and air inlet 3 is set
It is provided with blow vent between the bottom of main capsule 2, main capsule 2 and auxiliary capsule 4, main capsule 2 is by blow vent and the UNICOMs of Fu Nang 4, main capsule 2 and auxiliary
The lateral exhaust outlet with hasp is equipped with capsule 4, sling or hook are distributed in the upper end of main capsule.
Further, air bag is compressed to necessarily when the lateral exhaust outlet with hasp on main capsule 2 and auxiliary capsule 4 is used to land
Internal pressure final vacuum, realize the landing buffer to air-drop equipment.
Further, auxiliary capsule 4 is provided with multiple exhaust outlets, is sewed with vent cap on the inside of the exhaust outlet of auxiliary capsule 4, plays on or off
Closing exhaust buckle closure can make exhaust outlet can be at using or prohibitting the use of state；To adjust the quantity of exhaust outlet, buffer air bag is realized
Buffer the regulation of efficiency.
Further, the material of buffer air bag is flexible gas impermeable material.
Further, the bottom of buffer air bag is provided with becket bridle 8, is connected by becket bridle 8 with bottom plate 9.
Further, the material of bottom plate 9 is aluminium sheet, and through hole is arranged among bottom plate 9, is inflated for buffer air bag.
Further, the periphery of bottom plate 9 carries connecting hole, mutually assembled for multiple bottom plates 9；Expand as multiple buffering gas
Capsule, adapts to the air-drop equipment of different area, and the difference that weight is equipped according to air-drop carries out group from the buffer unit of varying number
Close.According to equipment weight and the difference of height above sea level before air-drop, required buffering efficiency and exhaust outlet quantity are calculated, and regulate
The use state of each exhaust outlet.
Further, the upper end of bottom plate 9 is surrounded by connecting seat, and buffer air bag is interior logical without gas, bottom plate 9 before dropping out machine
Cross connecting seat to be connected with air-drop equipment bottom, separate connecting seat after dropping out machine.
Further, connecting seat is connected by latch with air-drop equipment bottom.
The operation principle of the present invention：
Before equipping out machine, connector that the bottom plate 9 of buffer unit is pulled pin by band is fixed on air-drop equipment bottom, at air bag
It is located in folded state between bottom plate 9 and air-drop equipment.After equipping out machine, air-drop deceleration is carried out using umbrella system, in umbrella system
Main risers when stretching, extract buffer unit and fix and pulls pin, bottom plate 9 falls in the presence of deadweight, stretches buffer air bag, main gas
Capsule is by bottom inflow hole from inflation is fallen, and after air bag contacts with ground, air inlet 3 is closed, and main gasbag is compressed backward auxiliary
Air bag starts to be vented, and after auxiliary air bag is full of, internal pressure overcomes the adhesive force of pull stap, and exhaust open simultaneously starts release.It is buffered
Cheng Zhong, main gasbag undertake cushioning effect, and auxiliary air bag compressed air plays a part of to delay degassing and stable equipment.
In figure 3, buffer unit is divided into air bag and the two large divisions of bottom plate 9.Air bag is stumbled by the rope at top and 1 is connected to air-drop
Bottom is equipped, air bag realizes the connection with bottom plate 9 by the becket bridle 8 of bottom through the connecting hole that bottom plate 9 is reserved., will before installation
Airbag fold is good, with multiple latches by multiple connecting seats on bottom plate 9 and the corresponding connecting seat fix tightly in air-drop equipment bottom
Lean on, multiple latches are connected on main chute system suspender belt with the connect band or steel wire rope that are of convenient length；Bottom plate 9 is set to be close to air-drop dress
Standby bottom, in order to which system goes out machine.
Fig. 3 it is specifically used during, after aerial delivery system goes out machine, when main chute system suspender belt stretches, latch connect band is pulled out
Go out all latches, bottom plate 9 separates with air-drop equipment bottom.Bottom plate 9 is fallen due to deadweight, so as to which the air bag of folded state be drawn
Straight expansion, meanwhile, during aerial delivery system falls, air bag is continuous by the air inlet 3 of bottom plate 9 and air bag bottom air inlet 3
Air is filled with, main capsule 2 and portion of secondary capsule 4 can be full of.When bottom plate 9 lands, air inlet 3 is closed, and intracapsular gas is produced by compression
Deformation, air-drop equipment impact energy is absorbed, and be vented by main capsule 2 by blow vent 5 to auxiliary capsule 4, make the gas in major-minor capsule 4
As an entirety, when the air in air bag reaches certain pressure, outwards it is vented by the outside exhaust outlet 6 of main capsule 2 and auxiliary capsule 4
Mouth 7 discharges compressed air, in time the absorbed energy of release, so as to reach the purpose that buffering equipment overloads.
In summary, because this buffer unit need not carry source of the gas, air is filled with by falling mode certainly, can combine makes
With, and buffering effect can be adjusted, therefore the air-drop equipment of various different weights is can be applied to, it is also applied for a variety of height above sea level
Highly, upland plain is general.
The interest field for being only presently preferred embodiments of the present invention, the present invention can not being limited with this certainly above,
Therefore the equivalence changes made according to scope of the present invention patent, still belong to protection scope of the present invention.
