Description
Technical field
The present invention relates to a kind of technology in rehabilitation technique field, the health of specifically a kind of automatic adjusument pressure
Knee-pad.
Background technique
The major function of existing knee-pad is health care, warming, shatter-resistant and athletic protective, is broadly divided into athletic protective knee-pad and guarantor
Strong type knee-pad.Above-mentioned knee-pad mostly utilizes the fitting of the forms such as velcro to fix, and lacks automatic pressure regulatory function.It is sent out after investigating
Existing, user is accustomed to skin-proximal and wears for a long time, causes when knee joint does not move or exercise intensity is lower still to knee-pad
There is dependence, this will reduce the use of ligament and muscle, and ligament and muscular atrophy will be caused when serious.
Summary of the invention
The present invention In view of the above shortcomings of the prior art, proposes a kind of health knee-pad of automatic adjusument pressure,
Knee-pad pressure can be rationally adjusted according to knee joint loading conditions, avoid negative effect caused by long periods of wear knee-pad.
The present invention is achieved by the following technical solutions:
The present invention include: be set on knee-pad cover pass sequentially through conduit connection inflate pressing mechanism, steam leak-off valve, air bag
And safety valve, different exercise intensities is suitable for without external energy.
The pressurizing device of inflating includes: connecting rod, piston and inflator, in which: piston is set in inflator, connecting rod
It is fixed on the top half of knee-pad cover and parallel with inflator axis.
The steam leak-off valve is tee tube, in which: first outlet and second outlet each by conduit respectively with inflate plus
Press mechanism is connected with air bag, and third outlet is connected to outside.
Technical effect
Compared with prior art, the energy of the present invention is not necessarily to external energy from user, is suitable for all knee-pads and energy
Gasbag pressure is enough adjusted according to the change of user's exercise intensity, knee joint is avoided to generate dependence to knee-pad.

Specific embodiment
As shown in Figure 1, the present embodiment includes: knee-pad cover 1, fixed mechanism 2, inflates pressing mechanism 3, steam leak-off valve 4, safety valve
5 and air bag 6, in which: inflating pressing mechanism 3, steam leak-off valve 4, air bag 6 and safety valve 5 passes sequentially through the connection of conduit 7 and by fixed machine
Structure 2 is set on knee-pad cover 1.
The fixed mechanism 2 includes: bracket 8 and support 9, in which: pressing mechanism 3 of inflating be fixedly connected with bracket 8 and
It inflates one end of pressing mechanism 3 and bracket 8 is set to the knee two sides of knee-pad cover 1 by support 9 respectively.
The pressing mechanism 3 of inflating includes: connecting rod 10, piston and inflator 12, in which: piston is set to inflator 12
Interior, connecting rod 10 is fixed on the top half of knee-pad cover 1 and parallel with 12 axis of inflator.
As shown in Fig. 2, the steam leak-off valve 4 is tee tube, in which: first outlet 13 and second outlet 14 are each by leading
Pipe respectively with inflate pressing mechanism 3 and air bag 6 is connected, third outlet 11 is connected to external.
One end of the safety valve 5 is connected by conduit 7 with air bag 6, and the other end is connected to outside.
The air bag 6 is set to the inside of knee-pad cover 1.
The knee-pad cover 1 is made of flexible material.
Above-mentioned apparatus works in the following manner: the present invention is worn at the knee joint of user, when initial, and air bag 6
Interior gauge pressure is zero, and knee-pad is provided knee joint contention effect by knee-pad cover 1, and oppresses effect and depend on the tightness worn；
When movement, kneebend is done in leg, the variation of knee joint angle generating period, and drive inflate pressing mechanism 3 connecting rod it is opposite
Inflator 3 is moved and is inflated, and gas enters conduit 7, and when by steam leak-off valve 4, gas flows into the amount of next section of conduit 7 far more than leakage
Enter the amount of atmosphere, so that gas be made to enter air bag 6,6 pressure of air bag increases and expands, and the air bag 6 of expansion is constrained by knee-pad cover 1,
And additional oppressive force is generated to knee joint, to realize fixed knee joint, the function of knee angle motion amplitude is limited, is played
It protection knee joint, the effect that avoids its amount of exercise excessive；With the increase of exercise intensity, knee joint bending knee frequency increases, and draws
It plays 6 charge flow rate of air bag to increase, increases additional oppressive force with exercise intensity, kneed limited degree is also increased therewith
By force；When 6 air pressure of air bag is greater than the threshold value of safety valve 5, safety valve 5 is opened, and gas is through conduit 7 from 5 row of safety valve in air bag 6
Out, 6 air pressure of air bag reduces, and prevents the excessive bring harm of air pressure；When stop motion, gas flows to gas leakage through conduit 7 from air bag 6
Valve 4, gas enter atmosphere, and gauge pressure is restored to zero in air bag 6, and air bag 6 and knee-pad disappear to kneed excess enthalpy oppressive force, avoid
Unnecessary limitation is carried out to knee joint.
(frequency is about 6Hz) utilizes the human body in the use process of pressure sensor completion in the case of lift leg is jogged in situ
The verifying of comfort level is analyzed.The pressure regulation spectrum that test obtains the knee-pad product is 0~12.97kPa, changes pressure limit to survey
Examination person does not cause discomfort；Pressure value slowly rises in motion process, and remains constant, and pressure slowly declines after stop motion,
Wherein the ascent stage time is about 15s, and time decline stage is 7~10s, it can be deduced that overview knee-pad product can be according to user
Motion of knee joint effectively carries out pressure adjusting；It is examined according to the knee-pad protecting effect that VICON motion capture system is completed.Measurement ginseng
Number is the variations (Angle of Knee Joint, write a Chinese character in simplified form: AKJ) of motion process knee angle, is moved in walking and jogging two kinds
Time Change lower and without the AKJ obtained in the case of knee-pad, wearing knee-pad cover, three kinds of this product of wearing.According to there is shield
Knee and the comparison that AKJ changes under no knee-pad, the product is only knee-pad cover to the limited angular size of knee joint angle when walking
Half, and it is almost the same with knee-pad cover when jogging, it can be deduced that and the product can be strong according to different motion of knee joint
Degree makes different limitations to knee joint.
Compared with prior art, the performance indicator promotion of this method is to realize to knee-pad to knee joint pressure with knee joint
The adjusting of exercise intensity variation, this adjusting is realized in no external power supply, merely with the energy of user itself.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the principle of the invention and objective with difference
Mode carry out local directed complete set to it, protection scope of the present invention is subject to claims and not by above-mentioned specific implementation institute
Limit, each implementation within its scope is by the constraint of the present invention.
