Technical field
The utility model relates to field of medical device, in particular, being related to a kind of Medical joint nursing stretching device.
Background technique
Currently, our countries have progressed into aged society, aged's ratio rapid growth.And the pass of the elderly
Section, including shoulder joint, knee joint etc. be easy to appear various illness, for example, arthritis be exactly in, it is common complaint among the elderly, multiple
Disease brings insufferable pain and torment to patient.During joint recovering, need to carry out fortune appropriate to joint part
It is dynamic to take exercise, the progress of joint recovering is improved, currently, the training device for stretch nursing for joint is also fewer.This is existing
There is the shortcoming of technology.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of Medical joints to nurse stretching device, and stretching is facilitated to close
Section.
The utility model adopts the following technical solution realizes goal of the invention:
A kind of Medical joint nursing stretching device, including bottom plate, it is characterized in that: the bottom plate upper end is fixed with fixed block,
The upper end of fixing block is fixed with motor, and the motor output shaft is fixedly connected with crank, and the crank is hingedly propped up by cylinder one
Strut, for the support rod by the hinged rotor plate of cylinder two, the rotor plate upper end is fixedly connected with arc-shaped rack, the arc-shaped gear
Meshing gear, the gear are connected by key in Rotational Cylindrical, and one end of the Rotational Cylindrical is fixedly connected with round turntable, described
Round turntable ring set tension belt, the other end of the Rotational Cylindrical pass through one end of groove hinged support column, the support column it is another
One end is fixedly connected on the bottom plate, and fixed there are two fixed column on the bottom plate, two fixed columns are fixedly connected with branch
The both ends of support, support frame as described above pass through the rotor plate.
As further limiting for the technical program, the rotor plate is sector structure, and rotor plate upper end two sides are solid
It is fixed that there are two baffles.
Compared with prior art, the advantages and positive effects of the utility model are as follows: the bottom plate of this device is placed on level
On face, tension belt is covered in knee joint position, motor is started, crank rotation is driven by motor output shaft, crank passes through cylinder
One drives support rod mobile, and support rod is hinged on rotor plate by cylinder two, to drive rotor plate to swing, and then arc-shaped gear
Item swings back and forth with rotor plate, arc-shaped rack meshing gear, and gear drives Rotational Cylindrical to swing by key, and round turntable also comes on
Backswing is dynamic, swings so that tension belt stretches the knee-joint reciprocating of middle old man, carries out activity appropriate to knee joint and takes exercise, promotes
Knee joint early recovery.

Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
As Figure 1-Figure 5, the utility model includes bottom plate 3, and 3 upper end of bottom plate is fixed with fixed block 4, the fixation
4 upper end of block is fixed with motor 5, and 5 output shaft of motor is fixedly connected with crank 6, and the crank 6 passes through one 7 hinged support of cylinder
Bar 8, for the support rod 8 by the hinged rotor plate 12 of cylinder 2 15,12 upper end of rotor plate is fixedly connected with arc-shaped rack 10, institute
10 meshing gear 11 of arc-shaped rack is stated, the gear 11 is connected in Rotational Cylindrical 13 by key 19, one end of the Rotational Cylindrical 13
It is fixedly connected with round turntable 2, the other end of the 2 ring set tension belt 1 of round turntable, the Rotational Cylindrical 13 is hinged by groove 14
One end of support column 18, the other end of the support column 18 are fixedly connected on the bottom plate 3, are fixed with two on the bottom plate 3
A fixed column 17, two fixed columns 17 are fixedly connected with the both ends of support frame 16, and support frame as described above 16 passes through the rotor plate
12。
The rotor plate is sector structure, and the 12 upper end two sides of rotor plate are fixed, and there are two baffles 9.
The workflow of the utility model are as follows: place the bottom plate 3 of this device in the horizontal plane, by 1 set of tension belt in knee
Joint position starts motor 5, drives crank 6 to rotate by 5 output shaft of motor, crank 6 drives support rod 8 to move by cylinder 1
Dynamic, support rod 8 is hinged on rotor plate 12 by cylinder 2 15, so that rotor plate 12 be driven to swing, and then arc-shaped rack 10 with
Rotor plate 12 swings back and forth, 10 meshing gear 11 of arc-shaped rack, and gear 11 drives Rotational Cylindrical 13 to swing by key 16, round turntable
2 also and then swing back and forth, and swing so that tension belt 1 stretches the knee-joint reciprocating of middle old man, carry out work appropriate to knee joint
It is dynamic to take exercise, promote knee joint early recovery.
Disclosed above is only a specific embodiment of the utility model, and still, the utility model is not limited to this,
The changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
