Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

As shown in figures 1-6, the whole device converts rotary motion into reciprocating motion through a transmission system, and extrudes and stretches a damping system through the reciprocating motion, so that the damping of the small-sized common rehabilitation training device is adjustable.

As shown in figure 1, the whole structure of the device, namely the shell 1, is in a straight cylinder shape, the space occupation is small, the bottom is large, and the stability of the device is effectively improved. The lateral wall of the shell 1 is of a detachable structure, and the spring is convenient to replace according to the condition of rehabilitation training. An end cover 2 is arranged at the upper end of the shell 1, and a handle for a rehabilitation person to hold is arranged on the end cover 2.

The entire transmission system is shown in fig. 2 and 3. A longitudinal mounting plate 4 is fixedly mounted at the central position inside the shell 1, and a transmission system is mounted on the mounting plate 4. The transmission system is divided into two units, namely a rotating unit and a reciprocating unit. As shown in fig. 1 and 2, a driving shaft 5 is installed at a central position of the mounting plate 4, and the driving shaft 5 extends out of the housing 1 and is connected with an external pedal 7 through a crank 6. During rehabilitation training, a trainer sits on a chair with a proper height and performs rotation training by stepping on the pedal 7 with feet. As shown in fig. 3 and 4, a drive gear 8 is attached to the

drive shaft

5, 1# driven

shafts

9 and 2# driven shafts 10 symmetrical with respect to the drive shaft 5 are attached to the attachment plates 4 on both left and right sides of the drive shaft 5, and the drive gear 8 is driven in mesh with a 1# driven gear 11 attached to the left 1# driven shaft 9 and a 2# driven gear 12 attached to the right 2# driven shaft 10, respectively. So that the rotational direction and the rotational speed of both driven gears are the same. Meanwhile, half gears 13 are mounted on the 1# driven shaft 9 and the 2# driven shaft 10 respectively, the structure of each half gear is shown in fig. 5, the included angle formed by the two connected sections is 170-180 degrees, and a 180-degree horizontal section can be formed after one tooth is added to each of the two sections. The design is to avoid mutual interference between the left and right gear half-gears 13 during the engagement or disengagement of the rectangular rack, which would cause the locking problem of the rectangular rack 20. The half gear 13 mounted on the 1# driven shaft 9 and the 2# driven shaft 10 are in the same position, so that the half gear 13 on the 2# driven shaft 10 can be meshed with the teeth 13 on the rectangular rack 13 at the right moment after the half gear 13 on the 1# driven shaft 9 is separated from the rectangular rack 13. The transmission systems are all rotary units.

As shown in fig. 3 and 6, the rectangular rack 13 is an external tooth rack, the rectangular rack 20 is connected with the upper plate 15 and the lower plate 16 through the connecting rod 18, and the upper plate 15 and the lower plate 16 are driven to synchronously ascend or descend by the half gear 13 in the process of driving the rectangular rack 13 to reciprocate. The inner surface of the shell 1 is provided with a guide groove 14, a limiting slide block 17 arranged on the upper plate 15 and the lower plate 16 is nested in the guide groove 14, and the limiting fit of the limiting slide block 14 and the guide groove 14 enables the upper plate 15 and the lower plate 16 to move only in the vertical direction, so that the movement deviation is prevented.

The whole transmission system is symmetrically arranged on the two mounting plates 4, so that the weight of the two ends is the same, the stress is the same, and the stability of the whole device is ensured.

Damping system as shown in fig. 2, detachable springs 21 are installed between the upper plate 15 and the end cover 2 and between the lower plate 16 and the bottom surface of the housing, and the amount of damping is adjusted by adjusting the number of the springs 21.

When the chair is used specifically, a trainer needs to sit on the chair, adjust the number of the appropriate springs and perform rehabilitation training by stepping on the pedal. The device is small in size, low in manufacturing cost and not limited by the size of a space, and can also be suitable for office people who sit for a long time.
