Open substantially until the patient's arms remain in the same plane in a bilateral orientation and back. The above operations are cyclically performed.
Example three:
in the second embodiment, the fixed width cannot be adapted to different people due to the different widths of the two arms of different individuals.
Therefore, in the present embodiment, as shown in fig. 3, 4, 5, 8 and 9, an adjusting device is further included, which includes a driving portion, a first adjusting portion and a second adjusting portion;
as shown in fig. 5 and 6, the driving part includes an adjusting lever, a driving gear 60 and a locking part, the adjusting lever is rotatably disposed on the support base 11 for driving the driving gear 60 to rotate; the lock portion is used for braking the drive gear 60;
as shown in fig. 1 and 8, the first adjusting portion includes a first connecting block 40, a first rack 42, a first slider 43 and a first rotating handle 44, the first connecting block 40 is used for connecting the first rack 42 and the first supporting arm 41, and the first rack 42 is matched with the driving gear 60; the first sliding block 43 is slidably disposed on the first rack 42, wherein the first rack 42 is provided with a first sliding slot 421, the first sliding block 43 is slidably disposed in the first sliding slot 421, one end of the first rotating handle 44 is rotatably disposed on the adjusting rod, and the other end is fixedly connected to the first sliding block 43;
as shown in fig. 3, the second adjusting part includes a second connecting block 50, a second rack 52, a second slider 53 and a second handle 54, the second connecting block 50 is used for connecting the second rack 52 and the second supporting arm 51, and the second rack 52 is matched with the driving gear 60; the second sliding block 53 is slidably disposed on the second rack 52, wherein the second rack 52 is provided with a second sliding groove 521, the second sliding block 53 is slidably disposed in the second sliding groove 521, one end of the second rotating handle 54 is rotatably disposed on the adjusting rod, and the other end is fixedly connected to the second sliding block 53;
the first rack 42 and the second rack 52 are located on opposite sides of the driving gear 60, and when the driving gear 60 rotates, the first supporting arm 41 and the second supporting arm 51 are driven to approach or separate from each other.
Since the first rack 42 and the second rack 52 are located at both sides of the driving gear 60, a height difference exists between the first supporting arm 41 and the second supporting arm 51, and the first connecting block 40 and the second connecting block 50 can compensate for the height difference, so that the first supporting arm 41 and the second supporting arm 51 can keep the same height in the vertical direction, and the arm condition of the actual human body can be approached.
When the adjusting device works, when the distance between the first supporting arm 41 and the second supporting arm 51 needs to be adjusted, the adjusting rod is rotated to enable the adjusting rod to drive the driving gear 60 to rotate, and when the driving gear 60 rotates, because the first rack 42 and the second rack 52 are located on two sides of the driving gear 60, the driving gear 60 rotates to drive the first rack 42 and the second rack 52 to move towards opposite directions, so that the first supporting arm 41 and the second supporting arm 51 are driven to move towards or away from each other, and the distance between the first supporting arm 41 and the second supporting arm 51 is adjusted. During the adjustment process, the first slider 43 slides in the first sliding groove 421, the second slider 53 slides in the second sliding groove 521, and during the adjustment process, when the first support arm 41 and the second support arm 51 move toward each other or back, the first pull rod 33 and the second pull rod 34 are driven to move, so that the linkage block 32 is forced to move up and down, and the sliding space of the linkage block 32 is provided by the space between the first limiting block 311 and the second limiting block 312. When the adjustment is completed, the drive gear 60 is locked by the locking portion.
When the lifting cylinder 30 acts, the driving rod 31 is driven to move upwards, before the first limiting block 311 butts against the linkage block 32, the lifting cylinder 30 has no stroke, and when the first limiting block 311 butts against the linkage block 32, the linkage block 32 is driven to move upwards; the process of the lifting cylinder 30 is similar when moving in the reverse direction, the driving rod 31 firstly performs a section of idle stroke, and when the second limiting block 312 butts against the linkage block 32, the linkage block 32 is driven to move. When the linkage block 32 acts, the first pull rod 33 and the second pull rod 34 are driven to act, the first pull rod 33 and the second pull rod 34 are stressed, and because the first rotating handle 44 and the second rotating handle 54 are both rotatably arranged on the adjusting rod, the first rotating handle 44 drives the first supporting arm 41 and the second rotating handle 54 drives the second supporting arm 51 to rotate along the axial lead of the driving gear 60, and by enabling the first supporting arm 41 and the second supporting arm 51 to rotate along the same axial lead and act synchronously, the rotating speed, amplitude and preset rotating direction of the first supporting arm 41 and the second supporting arm 51 can be ensured to be close to the action process of the medical staff arms (when the medical staff arms drive the patient arms to overturn, the medical staff arms basically keep rotating around the same rotating center), and the training effect is improved. The first rack 42 and the second rack 52 are both meshed with the driving gear 60, and in the rotating process of the first supporting arm 41 and the second supporting arm 51, the first rack 42 and the second rack 52 both roll on the driving gear 60 at the same rotating angle, so that synchronous action can be realized.
Specifically, as shown in fig. 5 and 6, the locking part includes a first spring 62 and an externally splined rod 611, one end of the first spring 62 is connected to the support table 11, and the other end is connected to the adjusting lever, for enabling the adjusting lever to be reset when no external force is applied;
as shown in fig. 6, a receiving hole is coaxially formed on the driving gear 60, and the adjusting rod is slidably disposed in the receiving hole; the adjusting rod is provided with a yielding section 612, and the diameter of the yielding section 612 is smaller than that of the accommodating hole, so that the yielding section 612 cannot interfere with the accommodating hole;
the outer spline rod 611 is coaxially and fixedly arranged on the abdicating section 612, the abdicating section 612 is longer than the outer spline rod 611, the inner spline 601 is arranged inside the accommodating hole, that is, part of the abdicating section 612 is an inner spline 601 hole and part of the abdicating section 612 is a unthreaded hole in the extending direction of the shaft axis of the accommodating hole, wherein the inner spline 601 is matched with the outer spline rod 611, so that the inner spline 601 and the outer spline rod 611 can be arranged in a staggered manner in the extending direction of the shaft axis, and can be separated from each other, or can be partially or completely overlapped, so as to realize driving connection, it can be understood that no matter the inner spline 601 and the outer spline rod 611 are staggered or overlapped, the adjusting rod is designed to not to be separated from the accommodating hole, that is, the length of the abdicating section 612 in the direction of the shaft axis should be shorter than the length of the accommodating hole in the direction of the shaft axis;
the adjusting rod at least has a first working state and a second working state;
when the adjusting rod is in the first working state, the first spring 62 is compressed, the external spline rod 611 is matched with the internal spline 601, and the adjusting rod can drive the driving gear 60 to rotate when rotating;
when in the second working state, the first spring 62 is extended, the externally splined rod 611 is disengaged from the internally splined rod 601, and when the adjustment rod is rotated, the driving gear 60 is not rotated.
After the step S1 and before the step S2, the method further comprises:
s11, pressing the adjusting rod to compress the first spring 62, and driving the outer spline rod 611 to move to be overlapped with the inner spline 601 by the adjusting rod so that the outer spline rod 611 and the inner spline 601 are in driving connection;
s12, rotating the adjusting lever to enable the adjusting lever to drive the driving gear 60 to rotate, wherein when the driving gear 60 rotates, because the first rack 42 and the second rack 52 are located at two sides of the driving gear 60, the driving gear 60 rotates to drive the first rack 42 and the second rack 52 to move in opposite directions, so as to drive the first supporting arm 41 and the second supporting arm 51 to move in the opposite direction or in the opposite direction, so as to adjust the distance between the first supporting arm 41 and the second supporting arm 51;
s13, after the adjustment is finished, the adjusting rod is loosened, and the adjusting rod is reset under the action of the first spring 62, so that the external spline rod 611 is separated from the internal spline 601.
During operation, if the distance between the first support arm 41 and the second support arm 51 needs to be adjusted, the adjusting rod is pressed to compress the first spring 62, and the adjusting rod drives the external spline rod 611 to move to overlap with the internal spline 601, so that the two arms are in driving connection. It can be understood that after the spline fit is disengaged, due to dislocation and the like, tooth positions may not be accurately matched when the spline fit is re-engaged, and at the moment, only the adjusting rod needs to be slightly rotated and force is applied along the axis direction, so that the tooth positions are matched and then meshed when the adjusting rod is rotated. When the external spline rod 611 is matched with the internal spline 601, the adjusting rod is rotated, the adjusting rod drives the driving gear 60 to rotate, and the driving gear 60 drives the first rack 42 and the second rack 52 to move in the opposite direction or in the opposite direction, so as to adjust the distance between the first supporting arm 41 and the second supporting arm 51.
Specifically, the feeding device is a feeding cylinder 20, and an output end of the feeding cylinder 20 is drivingly connected to the supporting table 11.
Example four:
when the patient moves, the hands are tightly held, other actions cannot be performed, that is, the control of the device is inconvenient, and during training, the shapes of the waist (abdomen) and the arms need to be monitored, when the waist (abdomen) is basically horizontal and the arms and the back are basically in the same horizontal plane, the movement is in place, and the next action needs to be performed (it can be understood that the initial switch action can be controlled through the hands or the feet, the embodiment focuses on the problem that whether the arms and the back are basically in the same horizontal plane, that is, whether the movement is in place or not), however, the guidance of medical staff is lacked, and when the patient trains alone, the body posture cannot be effectively controlled and monitored, and whether the next training step needs to be performed or not is judged, so the embodiment further comprises a limiting device and a control device;
as shown in fig. 7, the limiting device includes a supporting platform 11, a supporting plate 70, a pressing rod 71 and a second spring 72, the supporting plate 70 is fixedly arranged on the pressing rod 71, the supporting platform 11 is arranged on the base 10, a control chute is arranged on the supporting platform 11, the pressing rod 71 is arranged in the control chute in a vertically slidable manner, the second spring 72 is located in the control chute, one end of the second spring 72 is connected into the control chute, and the other end is connected to the pressing rod 71;
the control device comprises a controller and a travel switch, the travel switch is fixedly arranged in the control chute, and the travel switch can be touched in the process that the pressing rod 71 moves downwards; the travel switch, lift cylinder 30 and feed cylinder 20 are all signally connected to the controller.
The S3 specifically includes:
the feeding device acts to drive the supporting table to move towards the direction departing from the human body, so that the upper half of the patient is forced to bend forwards, in the process of bending the upper half of the patient forwards, the abdomen abuts against the supporting plate 70 and presses the supporting plate 70 downwards, the supporting plate 70 moves downwards to press the second spring 72, the second spring 72 is compressed, when the pressing rod 71 on the supporting plate 70 presses the travel switch downwards, the travel switch sends a signal to the controller, and the controller receives the signal to perform S4 action.
Furthermore, an external thread is arranged on the supporting platform 11, a thread adjusting hole is arranged on the base 10, and the supporting platform 11 is in threaded connection with the thread adjusting hole.
When the device works, the upper half of the patient leans forwards along with the backward movement of the feeding device, the abdomen leans against the supporting plate 70 in the forward tilting process, the supporting plate 70 is pressed downwards, the supporting plate 70 moves downwards to apply pressure to the second spring 72, the second spring 72 is compressed, when the pressure rod 71 on the supporting plate 70 is pressed downwards to the travel switch, the travel switch sends a signal to the controller, the controller receives the signal, and when the waist (abdomen) is adjusted in place, other components are controlled to perform the next step of action. It can be understood that, because the external thread arranged on the supporting platform 11 is matched with the thread adjusting hole on the base 10, the supporting platform 11 can be adjusted to lift through the thread, so that the pressing rod 71 is just touched to the travel switch under the standard posture according to different individual body positions.
Example five:
since the first support arm 41 and the second support arm 51 are relatively independent, when the upper body is turned over by applying a force to the waist after the preceding movement is completed, the first support arm 41 and the second support arm 51 need to rotate around the same axis, and the first pull rod 33 and the second pull rod 34 have the same movement direction during the rotation, but the drive rod 31 is fixed, which may hinder the operation of the device.
Therefore, in this embodiment, as shown in fig. 11, the lifting device further includes two third springs 35, a linkage sliding slot is formed on the supporting platform 11, and the lifting cylinder 30 is slidably disposed in the linkage sliding slot; the two third springs 35 are symmetrically arranged on two sides of the lifting cylinder 30, one end of each third spring 35 is connected to the lifting cylinder 30, and the other end of each third spring is connected to the inside of the linkage sliding groove.
Because the lifting cylinder 30 is slidably disposed on the supporting platform 11, when the first pull rod 33 and the second pull rod 34 are stressed, the displacement compensation in the horizontal direction can be provided by the sliding of the lifting cylinder 30, and the two third springs 35 are symmetrically disposed on the two sides of the lifting cylinder 30, so that the two sides of the lifting cylinder 30 are stressed in the same magnitude and in opposite directions, and after the training is finished, the lifting cylinder 30 can be automatically reset to return to the middle position.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
