Description
Technical field
The present invention relates to a kind of wheelchair leg shockproof structure, belong to medical instruments field.
Background technology
Wheelchair is the important tool of rehabilitation, and it is not only limbs the disabled and the walking-replacing tool of handicapped personage, heavier
Want is to make them carry out physical exercise by means of wheelchair and participate in social activity.Wheelchair sets as medical treatment its function of special equipment
Determining service object is specific crowd, to meet the needs that they ride instead of walk.Along with technological progress, living condition improve, to wheelchair
Functional requirement the most day by day increase, its each parts of inevitable requirement are updated, to adapt to the user's request improved constantly.In order to carry
High-comfort, present wheelchair device increasingly comes complicated, has not only installed power facility additional, saves manual fatigue, also strengthens
Structure setting, makes its easy to use and multifunction as far as possible.But wheelchair is as assistive device, during taking, shake
The dynamic leg being delivered to user can bring discomfort to user.
Summary of the invention
The deficiency existed for prior art, the technical problem to be solved is to provide a kind of wheelchair leg and prevents
Shake structure, leg vibration filtering is good, ride comfort.
For solving above-mentioned technical problem, the present invention adopts the technical scheme that, a kind of wheelchair leg shockproof structure, including with
Wheelchair side stand fixes the fixing post of connection, and the fixing epimere connecting post is provided with U-shaped junction button, and fixing post upper end connects lower limb
Portion's pole, the top of leg pole is connected by U-shaped junction button and leg pole are fixing；The lower end of described leg pole connects to be had
Pedal-rod, pedal-rod is provided with pedal, and pedal is rotationally connected with pedal-rod, and the stage casing of leg pole is provided with leg and props up
Fagging；Being provided with vibration absorbing device between described thigh support board and leg pole, vibration absorbing device includes propping up with leg
The support chip that fagging connects, support chip connects some arcuate struts be arrangeding in parallel, and one end connection of arcuate struts has U-shaped
The fixing sheet that connects, the fixing sheet that connects is socketed on leg pole, and fixing connection is provided with fixing bolt on sheet；Described arcuate struts
Arc opening in be provided with arc support rod, the arc opening direction of arc support rod and the house type opening direction of arcuate struts
On the contrary；It is provided with elastic fulcrum bar between described leg pole and pedal-rod.
Optimizing, above-mentioned wheelchair leg shockproof structure, the radian of described arcuate struts is the length of pedal-rod and fixing post
1.47 times of ratio, arc support rod is socketed with balancing weight.
Optimizing, above-mentioned wheelchair leg shockproof structure, described elastic fulcrum bar is arc, and the radian of elastic fulcrum bar props up with arc
The radian of bar is identical.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.The design of the application
Vibration absorbing device is set between thigh support board and leg pole, is transferred into thigh support board by vibration absorbing device
Shock absorption, improve the comfortableness of user leg.Arcuate struts will be able to be shaken by elastic deformation when being given a shock
Dynamic absorption, prevents vibrations to be delivered in thigh support board.But its support strength of the pole of arc is low, strong in order to improve support
Degree, arranges arc support rod in the arc opening of arcuate struts, but arc support rod can be when arcuate struts be given a shock
Resonate with arcuate struts, reduce the shock-absorption of arcuate struts, therefore the design of the application is through digital modeling design meter
Draw, when 1.47 times by the lenth ratio that the radian of arcuate struts is pedal-rod and fixing post, resonate less.In order to incite somebody to action
Resonance energy absorbs, and is socketed with balancing weight on arc support rod.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1 be fixing post, 2 be U-shaped junction button, 3 be leg pole, 4 be pedal-rod, 5 be pedal, 6 be thigh support
Plate, 7 be support chip, 8 be arcuate struts, 9 for fixing connect sheet, 10 be arc support rod, 11 be elastic fulcrum bar.
Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The present invention is a kind of wheelchair leg shockproof structure, including fixing the fixing post being connected with wheelchair side stand, the company of fixing
The epimere connecing post is provided with U-shaped junction button, and fixing post upper end connects leg pole, and the top of leg pole is by U-shaped connection
Detain be connected fixing with leg pole；The lower end of described leg pole connects pedal-rod, and pedal-rod is provided with pedal, foot-operated
Plate is rotationally connected with pedal-rod, and the stage casing of leg pole is provided with thigh support board；Described thigh support board and leg pole it
Between be provided with vibration absorbing device, vibration absorbing device includes the support chip being connected with thigh support board, if support chip connect have
The dry arcuate struts be arrangeding in parallel, one end of arcuate struts connects U-shaped fixing connection sheet, and the fixing sheet that connects is socketed on leg
On pole, fixing connection is provided with fixing bolt on sheet；Arc support rod, arc it is provided with in the arc opening of described arcuate struts
The arc opening direction of shape support bar is contrary with the house type opening direction of arcuate struts；Set between described leg pole and pedal-rod
It is equipped with elastic fulcrum bar.The radian of described arcuate struts is 1.47 times of the pedal-rod lenth ratio with fixing post, arc support rod
On be socketed with balancing weight.Described elastic fulcrum bar is arc, and the radian of elastic fulcrum bar is identical with the radian of arcuate struts.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.The design of the application
Vibration absorbing device is set between thigh support board and leg pole, is transferred into thigh support board by vibration absorbing device
Shock absorption, improve the comfortableness of user leg.Arcuate struts will be able to be shaken by elastic deformation when being given a shock
Dynamic absorption, prevents vibrations to be delivered in thigh support board.But its support strength of the pole of arc is low, strong in order to improve support
Degree, arranges arc support rod in the arc opening of arcuate struts, but arc support rod can be when arcuate struts be given a shock
Resonate with arcuate struts, reduce the shock-absorption of arcuate struts, therefore the design of the application is through digital modeling design meter
Draw, when 1.47 times by the lenth ratio that the radian of arcuate struts is pedal-rod and fixing post, resonate less.In order to incite somebody to action
