There are leg frenulum 9 in 1 two sides of leg fixed plate, for tying up leg fixed plate 1 in leg；The sole support
There are foot's frenulum 6 in 5 two sides of plate, for tying up sole support plate 5 on foot or shoes.
3 head of support rod has piston to be nested in support cylinder 2, pushes support by the pressure oil in support cylinder 2
Bar 3 stretches out；3 bottom end of support rod is fixed in support base shaft 7, and support base shaft 7 is mounted in support base 8 and can phase
Support base 8 is rotated.
It is hinged in leg fixed plate 1 at the top of the support cylinder 2, push rod 14 is driven through drive rod 17 by motor 16
It moves back and forth, oil suction comes out and is pressed into support cylinder 2 from fuel tank 10；Lower channel in the support cylinder 2, which uses, to be differed
Section design, upper channel sectional area is small, and lower channel sectional area is big, and the piston of support rod 3 is located in lower channel.
The fuel tank 10 is provided with fuel tank check valve 20 with 11 connecting place of oil inlet pipe, guarantees that hydraulic oil can only be unidirectional from fuel tank
Flow into oil inlet pipe 11；Oil cylinder oil inlet check valve 21 is provided in the upper channel of support cylinder 2, so that pressure oil can only be from oil inlet pipe
Unidirectionally enter 2 upper channel of oil cylinder, the influence to avoid pressure oil to push rod 14 and oil inlet pipe 11.
It is provided with skewed slot on the drive rod 17, this skewed slot is end to end hollow slot；The end of push rod 14 is connected with rolling
Wheel 15, idler wheel 15 is stuck in the skewed slot of drive rod 17；The motor rotary shaft 18 of motor 16 links together with drive rod 17, electricity
When motivation 16 drives drive rod 17 to rotate, idler wheel 15 makees back and forth movement in the skewed slot of drive rod 17, so that push rod be driven to complete
Oil suction and pressure oil movement.
Bottom is equipped with travel switch in the support cylinder 2, when support rod 3 is completely out, the piston on 3 head of strut
It triggers travel switch and issues signal, so that motor 16 stops rotating, pressure oil does not enter back into support cylinder 2, and system pressure is protected
It holds, provides and support is stablized to leg.
Pressure switch 4 is installed in the sole support plate 5, when foot lifts, pressure switch 4 loses pressure and makes electricity
It controls check valve 22 to open, pressure oil is through 22 oil return box of electric control one-way valve, hydraulic system off-load；When vola generates pressure switch 4
When certain pressure, triggering pressure switch 4 issues electric signal, so that electric control one-way valve 22 is closed, while motor 16 starts to rotate,
Supporting process is lifted into leg next time.
Present apparatus working principle is as follows:
Motor 16 drives drive rod 17 to rotate through 18 shaft of motor rotary shaft, and the skewed slot pushing rolling wheels 15 in drive rod 17 are made past
Movement is returned, idler wheel 15 drives push rod 14 to complete oil suction and pressure oil movement.Oil liquid under the action of push rod 14 in fuel tank 10 passes through
Fuel tank check valve 20 enters oil inlet pipe 11, flows subsequently through the upper channel that oil cylinder oil inlet check valve 21 enters support cylinder 2.Support oil
Lower channel in cylinder 2 is designed using unequal section, and upper channel sectional area is small, and lower channel sectional area is big.The piston position of support rod 3
In lower channel, since active force is equal to pressure multiplied by active area in hydraulic drive, jack principle, Ke Yitong are utilized in this way
It crosses lesser pressure and obtains biggish pressure.

Bottom support plate 5 can not move down on ground, and reaction force jacks support cylinder 2.It is hinged at the top of support cylinder 2
On the bottom surface of leg fixed plate 1, support cylinder 2 drives the oil cylinder hinge joint of leg fixed plate 1 to move up by jacking.Since leg is solid
Fixed board 1 is tied up when using in leg, and the oil cylinder hinge joint of leg fixed plate 1 moves up so that leg is lifted, while the song of leg
It stretches so that the rotation of certain angle occurs around oil cylinder hinge joint for leg fixed plate.When support rod 3 is completely out, 3 head of strut
Piston triggering travel switch issue signal so that motor 16 stops rotating, pressure oil does not enter back into support cylinder 2, system
Pressure is kept, and is provided and is stablized support to leg.
Pressure switch 4 is installed, when foot lifts, pressure switch 4 loses pressure and makes automatically controlled list in sole support plate 5
It is opened to valve 22, pressure oil is through 22 oil return box of electric control one-way valve, hydraulic system off-load, with lifting for foot and shank, supports
Bar 3 retracts inside support cylinder 2；Sole support plate 5 again when being contacted with ground, when vola generates a level pressure to pressure switch 4
When power, triggering pressure switch 4 issues electric signal, so that electric control one-way valve 22 is closed, while motor 16 starts to rotate, under
One time leg is lifted supporting process.
When support rod 3 is completely out, the plate face of leg fixed plate 1 and the plate face of sole support plate 5 are close to vertically；Support rod
3 when being fully retracted, and the plate face of leg fixed plate 1 and the plate face of sole support plate 5 are close to parallel.
After foot's frenulum 6 unclamps, sole support plate 5 is moved back, can be used as auxiliary seat use, is user in fatigue
When effective rest mode is provided.At this point, pressure switch 4 loses pressure electric control one-way valve 22 is opened, hydraulic system off-load.
During sitting down, support rod 3 retracts inside support cylinder 2 user, until the piston-top surface of support rod 3 seals branch completely
The oil return opening of oil cylinder 2 is supportted, support rod 3 heads on support cylinder 2 and provides support to human body by leg fixed plate 1.
In the present embodiment, fuel tank and motor are all fixed on the bottom surface of leg fixed plate, and the power of motor is by battery
It provides.To mitigate leg weight bearing, fuel tank and motor can also be placed on to the other positions such as knapsack or waist ligature.
The above embodiments are merely illustrative of the technical solutions of the present invention and is not intended to limit it, all without departing from the present invention
Any modification of spirit and scope or equivalent replacement, shall fall within the scope of the technical solution of the present invention.
