It should be noted that: the axes of the two connecting rods 220 are parallel, and the explanation that the two connecting rods 220 are respectively located at both sides of the first rotating shaft 210 is as follows: when the two ends of the connecting rod 220 are defined as the left-right direction, the "two connecting rods 220 are respectively located at two sides of the first rotating shaft 210" means that "two connecting rods 220 are respectively located at front and rear sides of the first rotating shaft 210", and the specific shape may refer to a Z shape.

It should be noted that this embodiment is for sitting use by a patient. In this embodiment, the slide rail 110 is fixed at a desired position and used by sitting on an external chair. Therefore, the rehabilitation exerciser for severe patients of the present embodiment has an advantage of portability.

Example 2

Referring to fig. 2, on the basis of embodiment 1, the present embodiment further includes a supporting mechanism 300, where the supporting mechanism 300 includes a supporting frame 310, the supporting frame 310 is detachably disposed on the sliding rail 110, for example, by bolting, a supporting plate 320 is fixedly connected to an upper side of the supporting frame 310, and a backup plate 330 is rotatably connected to a side of the supporting plate 320, which can be locked.

Further, the two sides of the support frame 310 are provided with handrails 340, which can help the patient to be smooth.

Example 3

On the basis of the above embodiment, the following settings were made:

referring to fig. 3 and 4, the sliding rail 110 includes a fixing plate 111, and the fixing plate 111 has a first slide 1111 thereon; the sliding block 120 is slidably connected to the first slideway 1111;

the sliding block 120 is provided with a limiting plate 140, and the limiting plate 140 is attached to the side part of the first slideway 1111; for guiding the slider 120 to prevent detachment or tilting from the first slide 1111.

The first slide 1111 has a positioning slot 1112, and the slider 120 has a first positioning plunger 150 (not shown) that can be inserted into the positioning slot 1112.

In the present embodiment, the fixing plate 111 is provided as two parallel standing plates, and the lower sides of the two parallel standing plates are connected by a fixing rod. The first slide 1111 is disposed on each vertical plate, so that the rehabilitation exerciser of this embodiment is lighter and more convenient to carry.

The slider 120 is locked by inserting the first positioning plunger 150 into the positioning groove 1112 so that the first rotation shaft 210 does not move in the first mode.

Further, a plurality of positioning grooves 1112 are provided, so that the sliding block 120 can be fixed at different positions, and patients with different leg lengths can use the sliding block conveniently.

Further, the first slide 1111 is a curved slide. For example, the track of the first run 1111 is wavy. The slider 120 is reciprocally pushed back and forth, and the leg is driven to swing left and right, so that the leg of the patient can be moved in a small range.

Example 4

Referring to fig. 5 to 9, the following arrangements are performed on the basis of the above embodiments:

in this embodiment, one of the matching modes of the slider 120 and the first rotation shaft 210 is: referring to fig. 8, the slider 120 has a first accommodating hole 121 therein, and the first rotating shaft 210 is disposed in the first accommodating hole 121; with this arrangement, the first rotation shaft 210 can be rotated and axially moved with respect to the slider 120.

Further, the problems encountered with the above embodiments are: when the patient pushes the slider 120 to reciprocate along the slide rail 110 with the foot support second rotation shaft 230, the two feet of the patient are not positioned symmetrically, in which case the patient applies uneven force, which is inconvenient. And the two legs are stressed unevenly and even damage the legs, so the following settings are carried out:

referring to fig. 9, the first rotating shaft 210 includes a first split shaft 211 and a second split shaft 212, one end of the first split shaft 211 is fixedly connected with the connecting rod 220, the other end of the first split shaft 211 has a first accommodating groove 2111, one end of the second split shaft 212 is inserted into the first accommodating groove 2111, and the second split shaft 212 can axially rotate relative to the first split shaft 211.

With this arrangement, by the rotation of the first split shaft 211 and the second split shaft 212, the two second rotation shafts 230 can be adjusted to symmetrical positions, so that the two feet of the patient can be in symmetrical positions. However, the first mode of operation cannot be operated simply because the structure can adjust the positions of the two second rotating shafts 230.

The following settings were thus made:

with continued reference to fig. 8, the side wall of the first receiving hole 121 has a first annular groove 1211, and one side of the first annular groove 1211 has a first ramp 1212;

referring to fig. 6 and 7, the outer surface of the first split shaft 211 is attached to the side wall of the first accommodating hole 121, and the first split shaft 211 can axially move in the first accommodating hole 121; the first split shaft 211 is provided with a through hole 2112 which is arranged in the radial direction, and the through hole 2112 is communicated with the first accommodating groove 2111; the second split shaft 212 has a second receiving groove 2121 disposed radially, the second receiving groove 2121 has a second elastic member 2122 therein, an end of the second elastic member 2122 is connected to a second positioning insert rod 2123, one end of the second positioning insert rod 2123 can pass through the through hole 2112 and extend into the first receiving hole 121, and the second positioning insert rod 2123 can be inserted into the first annular groove 1211.

With the above arrangement, in the operation mode, one end of the second positioning insert rod 2123 passes through the through hole 2112 and extends into the first receiving hole 121 under the elastic pushing of the second elastic member 2122, and the second positioning insert rod 2123 can be inserted into the first annular groove 1211, at this time, the first split shaft 211 and the second split shaft 212 cannot rotate relatively due to the cooperation of the second positioning insert rod 2123 and the through hole 2112, so that the operation of the first operation mode can be supported.

When the second working mode is needed to be used, the patient pushes the connecting rod 220 by feet, so that the second split shaft 212 pushes the first split shaft 211 to axially move, the second positioning insert rod 2123 moves into the first accommodating groove 2111 under the pressing action on the first ramp 1212, the second positioning insert rod 2123 is separated from the through hole 2112 and is clamped with the through hole 2112, the first split shaft 211 and the second split shaft 212 can relatively rotate, so that the two second rotating shafts 230 move to symmetrical positions, and when the second working mode is used, the two feet of the patient are in symmetrical positions, in this case, the two legs of the patient are convenient to apply force, the force application is uniform, the stress on the two legs is uniform, and the probability of damaging the legs is reduced.

The advantages of the above arrangement are also:

first, during operation mode one, the second positioning insert rod 2123 is inserted into the first annular groove 1211, so that the first split shaft 211 can be limited in axial direction, and the first split shaft 211 can only move towards the first ramp 1212, but cannot move reversely. And the first split shaft 211 is difficult to move towards the first ramp 1212 without being pushed by external force, so that the first split shaft 211 and the second split shaft 212 can be axially limited.

Secondly, the working mode is conveniently switched. The preset target crowd of the rehabilitation exercise device is a severe patient, and the exercise is inconvenient. With this arrangement, the first split shaft 211 is driven by the foot to move axially.

Third, when the patient drives the first split shaft 211 to axially move and switch the working modes, the force in the opening and closing directions of the two legs can be exercised.

Example 5

In embodiment 4, the first split shaft 211 is pushed to move axially, so that the second positioning insert rod 2123 moves into the first accommodating groove 2111 under the pressing action on the first ramp 1212, so that the second positioning insert rod 2123 is disengaged from the through hole 2112, and thus the first split shaft 211 and the second split shaft 212 can rotate relatively, and the second positioning insert rod 2123 is not convenient to extend into the first accommodating groove 2111 because of the wall thickness between the outer layer of the first split shaft 211 and the first accommodating groove 2111, so that the following arrangement is made:

referring to fig. 10, the sidewall of the first receiving groove 2111 has a second annular groove 21111, and the second annular groove 21111 is aligned with the through hole 2112; the junction of the second annular groove 21111 and the through hole 2112 has a second ramp 21112, and one side of the second ramp 21112 extends to the outer layer of the first split shaft 211, the other side of the second ramp 21112 extends to the surface of the second annular groove 21111, and the end of the second positioning plunger 2123 has a rounded corner 21231.

In this embodiment, since the outer surface of the first split shaft 211 is fitted to the side wall of the first receiving hole 121, the second positioning insert 2123 can be pressed to one side of the second ramp 21112, and the end of the second positioning insert 2123 has the rounded corner 21231, so that the second positioning insert 2123 can be slid along the second ramp 21112 to the second annular groove 21111, and thus the second positioning insert 2123 can be easily inserted into the first receiving groove 2111.

In addition, the second annular groove 21111 may provide an axial stop for the second positioning plunger 2123.

Example 6

Referring to fig. 11-13, the second split shaft 212 has a third annular groove 2124, the third annular groove 2124 has a coil spring 2125 therein, and one end of the coil spring 2125 is fixedly connected with a clamping block 2126.

The second receiving groove 2121 has a second sliding way 21213 on a side wall, a third receiving groove 21214 is formed in the second sliding way 21213, and the clamping block 2126 is clamped in the third receiving groove 21214.

In this embodiment, the second split shaft 212 and the first split shaft 211 are connected by a coil spring 2125, so that the second split shaft 212 can be automatically reset.

While the step of disposing the coil spring 2125 between the second split shaft 212 and the first split shaft 211 is complicated, in this embodiment, the clip 2126 slides into the third receiving groove 21214 through the second slide 21213, facilitating installation.

Example 7

Referring to fig. 14, on the basis of the above embodiment, the following settings are made:

the outer surface of the first split shaft 211 has a fourth receiving groove 2113 for receiving the end of the first positioning plunger 150, and one side of the fourth receiving groove 2113 has a third ramp 2114;

the slider 120 has a second accommodation hole 122 communicating with the first accommodation hole 121, the first positioning insert rod 150 is slidably disposed in the second accommodation hole 122, the first positioning insert rod 150 is connected to an inner wall of the second accommodation hole 122 through a third elastic member 160, one end of the first positioning insert rod 150 can be inserted into the fourth accommodation groove 2113, and when one end of the first positioning insert rod 150 is inserted into the fourth accommodation groove 2113, the other end of the first positioning insert rod 150 is separated from the positioning groove 1112.

In this embodiment, the positioning groove 1112 is located on the sliding rail 110.

In the first operation mode, one end of the first positioning insert rod 150 is inserted into the positioning groove 1112, and the other end is abutted against the outer surface of the first split shaft 211, so that the sliding of the slider 120 can be prevented.

When the second operation mode is required to be switched, the first split shaft 211 is axially displaced, at this time, one end of the first positioning insert rod 150, which is in contact with the first split shaft 211, is inserted into the fourth accommodating groove 2113 under the driving of the third elastic member 160, so that the other end of the first positioning insert rod 150 is disengaged from the positioning groove 1112, at this time, the locking of the sliding block 120 is released, and the sliding block 120 can move relative to the sliding rail 110.
