Abstract
The utility model provides a manual power negative pressure exercising cabin for lower part of body and consists of a negative pressure cabin of lower body part, a sealed waistline, a manpower driver, a pressure-measuring meter, a piston, a gas tank, a single direction gas entering valve and a single direction gas-discharging valve, etc. The negative pressure cabin of the lower body part is a sealed and integrated cavity shell body made by steel plates and the cabin top is connected with the sealed waistline 2, ensuring the sealing performance of the negative pressure cabin of lower body part. The cabin is driven by the manpower driver 6, making the piston 9 reciprocate to discharge air out of the cabin to produce negative pressure in the cabin. The movement burden and the negative pressure level can be controlled by adjusting the caliber of the adjustable gas-entering valve 3. The cabin assembles lower part of body and sports practice and is easy to be operated. The cabin can be used in anti-burden practice of pilots and can prevent the body being affected by weightlessness.
Description
The present invention relates to a kind of aircrew's trainer.
Utilize the human centrifuge that the aircrew is trained with the positive acceleration endurance that improves the aircrew, reduces loss of consciousness incidence, though this method has been subjected to generally paying attention to, human centrifuge's apparatus expensive is difficult to popularize.Therefore, study a kind of novel replenish or substituting anti-G training method and apparatus imperative.In recent years, the LBNP cabin of being designed by the LBNP principle is tempered method and has been proved to be a kind of effective anti-G training measure.But present existing LBNP cabin needs attached power set, and can not have sports simultaneously.
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of convenience, safe and effective lower body negative pressure training device---man power lower body negative pressure training cabin to the aircrew.
The present invention has following characteristics: need not the additionaling power device and can produce LBNP voluntarily, integrate LBNP and physical training, cost is low, and is easy to use.Can be used for the aircrew and carry out anti-G training and antagonism weightleness physiological effect.
Realize that solution of the present invention is: the theory structure of the man power lower body negative pressure training cabin that is provided as shown in drawings.It partly is made up of LBNP cabin 1, sealing waistline 2, adjustable air intake valve 3, pressure gauge 4, vehicle seat 5, manpower driver 6, breather cheek valve door 7, one-way exhaust valve door 8, piston 9 and cylinder 10 etc.Now described in detail in conjunction with the accompanying drawings.
Accompanying drawing is the man power lower body negative pressure training cabin side view.
With reference to accompanying drawing.The airtight complete cavity housing of LBNP cabin 1 for constituting of the artificial power lower body negative pressure training cabin of the present invention by steel plate.1 top, LBNP cabin is pasted with annular rubber packing waistline 2, can be close to the human body waist, to guarantee the sealing property in LBNP cabin.Certain position of LBNP cabin 1 top front is also designed respectively adjustable air intake valve 3 and pressure gauge 4, and they all communicate with the inner chamber body in LBNP cabin.Handle 19 is made by stainless steel material, is fixed in LBNP cabin top front.Vehicle seat 5 is supported by stainless steel tube, is fixed on the base plate in LBNP cabin 1.Manpower drive part transmission principle is similar to bicycle.The wheel shaft 12 of manpower driver 6 is supported and is fixed on the LBNP Ceiling by axle stand.The pedal pedal makes manpower driver 6 drive chain drum 11 by its axle 12 and moves in a circle, and the chain drum periphery is with safety guard.Chain drum passes to chain drum 14 with its kinergety by chain 13, drives circle wheel 15 by axle 16 and rotates.Axle 16 is supported by axle sleeve and axle stand 17, and is fixed on the LBNP Ceiling.Circle wheel 15 drives piston 9 by drive link 18 and do straight reciprocating motion in cylinder 10.The airtight complete round barrel shape cavity housing of cylinder 10 for being made by steel is fixed on the LBNP Ceiling, and respectively there are a breather cheek valve door 7 and one-way exhaust valve door 8 in its two ends.Communicate in breather cheek valve door 7 and the LBNP cabin, 8 at one-way exhaust valve door communicates out of my cabin with LBNP.
During operation, trainer's lower body places in this LBNP cabin 1, is seated on the vehicle seat 5, holds handle 19.Adjust and tighten the annular rubber packing waistline 2 of waist, to guarantee the air-tightness in LBNP cabin.Both feet are pedaled the pedal on the moving power drive 6, and the driving chain driven gear sways circle wheel 15, and do straight reciprocating motion by drive link 18 drive pistons 9 in cylinder 10.When piston 9 during to an end motion, this end one-way exhaust valve door 8 is open, and breather cheek valve door 7 is closed, and gas is discharged from out of my cabin in the cylinder, and the other end then breather cheek valve door 7 is open, and one-way exhaust valve door 8 is closed, and gas enters cylinder in the cabin; When piston when the other end moves, situation is the same.The continuous repeating motion of trainer makes in the LBNP cabin gas constantly discharge out of my cabin, promptly produces negative pressure in the cabin, is used to carry out lower body negative pressure training.Can monitor LBNP cabin internal pressure in real time by pressure gauge 4.The trainer can come pressure-reduction level in controlled motion load and the cabin by regulating adjustable air intake valve 3 caliber size.
