Description
Technical field
The present invention relates to technical field of medical instruments, especially a kind of wheelchair damping device.
Background technology
At present, the application of wheelchair is wider, according to the demand of different use crowds, to the performance requirement more and more higher of wheelchair,
As there is the wounded leg, in Uneven road, if the shock-absorbing performance of wheelchair is bad, the secondary injury of patient is easily caused.
The patent of Application No. 200620165518.1 discloses a kind of damped wheelchair crawler, directly solid using decoupling rod
It is scheduled on the support of wheelchair, to reach the purpose of damping, the program can only slow down the vibrations that wheelchair vertical direction is subject to, it is impossible to subtract
The vibrations that slow wheelchair horizontal direction is subject to, and damping performance is bad.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of wheelchair anti-vibration structure, can improve the shock-absorbing of wheelchair
Can, it is to avoid cause the secondary injury of patient.
Realizing the principle of the present invention is：The support frame of wheelchair and the stator of spring are put with the left end and right-hand member of connecting rod respectively
Dynamic connection, the setting of connecting rod can slow down part vibrations, coordinate spring to use the damping performance for enhancing wheelchair.
It is based on above-mentioned principle the technical solution adopted in the present invention：Wheelchair damping device, including wheel shaft, are sleeved on wheel shaft
On stator, be connected with central axis in the spring of axle centre on stator, the other end of spring is connected with support
Frame, support frame and stator swing with the two ends of connecting rod be connected respectively, and the setting of connecting rod can slow down part vibrations, then match somebody with somebody with spring
Conjunction is used, and enhances the damping performance of wheelchair.
Support frame as described above be by first support bar, second support bar, the 3rd support bar, the 4th support bar group into quadrangle
The support frame of structure, wherein, the 3rd support bar, the 4th support bar are oppositely arranged, and spring, first are connected with the 4th support bar
The support of wheelchair is connected on strut, one end connection connecting rod that second support bar is connected with the 4th support bar, wherein, the 3rd support bar
Strengthen the fastness of Wheelchair support.
In its natural state, the line fixed on stator between connecting rod and two fixing points of spring and spring are into angle α
Set, α value is 60 ° to 68 °, the natural length of spring is 70mm, and its maximum weighted is 1470N, and maximal dilation distance is
The vertical range fixed on 40mm, the 4th support bar between spring and two fixing points of second support bar is 130mm, it is ensured that whole
The shock-absorbing performance of individual structure.
The beneficial effects of the invention are as follows：Connected between support frame and stator by connecting rod swing, part vibrations can be slowed down,
Again with coordinating spring to use, the damping performance of wheelchair is enhanced.
Brief description of the drawings
Fig. 1 is the three-dimensional structure diagram of the present invention.
Marked in figure：The support bars of 1- the 3rd, 2- first support bars, the support bars of 3- the 4th, 4- springs, 6- second is supported
Bar, 7- connecting rods, 8- stators, α-angle.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the structure of support frame when it is implemented, can by first support bar 2, second support bar 6, the 3rd
Strut 1, the integrally welded structure of the 4th support bar 3.
When being given a shock below the wheel being sleeved on wheel shaft, it is connected to after the stress of spring 4 on stator 8 and compresses,
Spring recovers to give the 4th support bar 3 one reaction forces during elastic force, is moved upwards after the stress of the 4th support bar 3, drivening rod 7
The one end being connected with the 4th support bar is moved upwards, reaches the purpose of damping.
When wheel advances, horizontal direction is given a shock, and is connected to the stress after-drawing of spring 4 on stator 8, and spring is extensive
Give the 4th support bar 3 one reaction forces during multiple elastic force, moved downward after the stress of the 4th support bar 3, drivening rod 7 and the 4th
One end of support bar connection is moved downward, and reaches the purpose of damping.
When wheel is retreated, horizontal direction is given a shock, and is connected to the stress after-drawing of spring 4 on stator 8, and spring is extensive
Give the 4th support bar 3 one reaction forces during multiple elastic force, moved upwards after the stress of the 4th support bar 3, drivening rod 7 and the 4th
One end of support bar connection is moved upwards, reaches the purpose of damping.
Connection between the application support bar and connecting rod, spring and between stator and spring, connecting rod, is connected using bolt
Connect, connecting rod swings and is connected with support bar, stator, remaining connection is to be fixedly connected.
