Adjustment rotational sleeve and pedestal may be selected around common axis by setting pedestal resistance adjustment mechanism in the technical solution
Make the size of the frictional resistance relatively rotated, in order to adapt to the rehabilitation training requirement of patient's different phase, improves the scope of application
And ability, for example, at rehabilitation training initial stage, can choose lesser frictional resistance, and arrived the rehabilitation training later period, can choose compared with
Big frictional resistance.
In the present embodiment, pedestal 60 is equipped with the base central hole 601 passed through for sleeve insertion axis 506, the base central
The bearing 602 being placed on sleeve insertion axis 506 is installed, thus to realize rotational sleeve 50 with pedestal 60 around public in hole 601
Axis L is relatively rotated.
In the present embodiment, it is cased with a cylindrical circular friction sleeve 508 on sleeve insertion axis 506, which circumferentially rubs
Face 501 is formed in the surface of friction sleeve 508.
In the present embodiment, the material of the friction sleeve 508 and sleeve axial direction friction pad 504 can be rubber.
The pedestal resistance adjustment mechanism includes the pedestal resistance regulation that can be rotatably set using common axis L as center of rotation
Handwheel 603;
The pedestal resistance regulation handwheel 603 is equipped with the pedestal cam profile that circumferentially extends around common axis L, the pedestal against
It also is provided with sliding block butting section on the sliding block 703 of mechanism, sliding block butting section and pedestal cam of the pedestal against the sliding block 703 of mechanism
Profile is kept in contact;
The pedestal cam profile include for changing pedestal against mechanism sliding block 703 in the position radially of shifting axle
Reducer 604 (that is, reducer has variation to diameter), the reducer 604 is in pedestal resistance regulation handwheel 603 around public affairs
Coaxial line L rotate when drive pedestal against mechanism sliding block 703 along shifting axle radial motion.
In the present embodiment, which is also the rolling being rotatably installed on thereon against the sliding block butting section of the sliding block of mechanism
Son 705.
Pedestal resistance adjustment mechanism structure disclosed in the technical solution is simple, and the adjusting of rotational resistance size is easy to operate fast
It is prompt.
In the present embodiment, the pedestal resistance regulation handwheel 603 is annular in shape, in the pedestal dynamic resistance adjusting handle 603
Heart line and common axis L are conllinear.
In the present embodiment, which is additionally provided with the pedestal radial through-hole 605 being connected to base central hole 601, the pedestal
It also include against shell 706 against mechanism, which is equipped with against shell sliding slot 707 in shell 706 against mechanism, should
Pedestal is equipped with wheel carrier opening 708 against one end against shell of mechanism, and the other end is equipped with sliding block opening 709, wheel carrier opening
With sliding block opening be connected to against shell sliding slot, the pedestal against the wheel carrier of mechanism, sliding block and power transmission spring be placed in against
In shell sliding slot, and pedestal slides cooperation with against shell sliding slot against the wheel carrier and sliding block of mechanism, so that wheel carrier and sliding block
It can be slid along the length direction against shell sliding slot, wheel carrier and sliding block constitute prismatic pair with against shell respectively;The wheel is provided with
The wheel carrier male arms 710 except shell is stretched out in through wheel carrier opening, which is rotatably installed in wheel carrier male arms;It should
Sliding block, which is equipped with, stretches out in sliding block male arms 711 except shell, roller of the pedestal against the sliding block of mechanism through sliding block opening
It is rotatably installed in sliding block male arms;The pedestal is inserted into pedestal radial through-hole 605 against mechanism against shell, at this point,
It is parallel to shifting axle radial direction against the length direction of shell sliding slot, which can also be locked against mechanism against shell by screw
Determine on the base.
In the present embodiment, pedestal also has three groups against mechanism, and three groups of pedestals are also circumferential etc. around common axis L against mechanism
It is distributed in spacing in pedestal 60, a pedestal cam profile is respectively configured against mechanism in each group of pedestal.Pass through three groups of weeks of setting
It can make rotational sleeve producing balanced forces (rolling frictional resistance) to the pedestal being equally spacedly distributed against mechanism, improve turning set
The stability and reliability of cylinder opposite base rotation.
In the present embodiment, pedestal 60 be in shaft-like, be divided into removable upper and lower two sections, wherein the upper section 606 of pedestal with
The pedestal annular hand slot 608 for accommodating pedestal resistance regulation handwheel 603 is equipped between the lower section 607 of pedestal.Pedestal it is upper
Section 606 and the lower section 607 of pedestal can be locked in together by screw, specifically, under the upper section and pedestal for locking pedestal
The screw rod of the screw of section screws in the upper section of pedestal after the lower section of pedestal, and the head indwelling of screw is in the lower section of pedestal.
One end of the reducer 604 of the pedestal cam profile is starting point 609, and the other end is terminal 610, the reducer
Partly without leave starting point 609 toward terminal 610 be incremented by.
