Description

Shoulder rotation stretching driving mechanism of physiotherapy chair

Technical Field

The utility model relates to the field of fitness and physiotherapy equipment, in particular to a shoulder rotating and stretching driving mechanism of a physiotherapy chair.

Background

The stretching exercise is a comfortable and relaxing health care exercise, and a sedentary person can relieve fatigue through stretching actions such as arm extension, head elevation and the like. Practice proves that the stretching movement can reduce the excitability of nerves and has a relieving effect on muscle spasms. The stretching exercise is often carried out, so that the fatigue caused by long-time work and labor can be relieved, and the body health is facilitated.

At present, fitness equipment with stretching effect is popular in communities, and people can achieve the purpose of stretching by operating the fitness equipment. However, the stretching mode is active, the physical strength of people is required to be consumed, the stretching function of the fitness equipment is single, and all parts of the people cannot be comprehensively stretched. For tired people, the chair can be used for comprehensively stretching all parts of the body without consuming physical power by sitting on the chair without going out, and the chair is enjoyed with health care effect.

The shoulder is most frequently used during work and is also most prone to fatigue. However, the existing physiotherapy chair lacks the rotation and unfolding actions of the shoulders, which is not beneficial to relieving the fatigue of the shoulders, so that a physiotherapy chair capable of comprehensively stretching the shoulders is needed.

It should also be noted that, in the description of the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; either directly or indirectly through intermediaries, or in communication with each other. The specific meaning of the above terms in the present utility model can be understood by those skilled in the art according to the specific circumstances.

A shoulder rotation stretching driving mechanism of a physiotherapy chair is shown in fig. 1-2, a pair of rotation driving devices are arranged on a chair back 1 of the physiotherapy chair, and a rotating rod 5 is connected to the rotating end of each rotation driving device. The rotating rod 5 is provided with an upper limb fixing band 6 for fixing an upper limb, and the chair back 1 is provided with a shoulder fixing band 7 for fixing a shoulder.

In the present embodiment, the rotation driving device is a motor 2 with a speed reducer 3, and the motor 2 can drive the rotation lever 5 to rotate after being energized. The upper limb fixing strap 6 and the shoulder fixing strap 7 are self-adhesive straps, the self-adhesive straps are provided with a hair surface and a hook surface, and the quick fixing of the upper limb and the shoulder can be realized through the adhesion of the hair surface and the hook surface of the self-adhesive straps.

When in physiotherapy, a person sits on the physiotherapy chair, the back leans against the chair back 1, the shoulders are fixed on the chair back 1 through shoulder fixing belts 7, and the upper limbs are fixed on the rotating rod 5 through upper limb fixing belts 6. The motor 2 and the speed reducer 3 drive the rotating rod 5 to rotate, and at the moment, the rotating rod 5 drives the upper limb to lift upwards, so that shoulder ligaments and shoulder joints can be lifted and stretched. The shoulder fixing strap 7 and the upper limb fixing strap 6 are used for limiting the rotation force applied by the motor 2 to the rotating rod 5 to the region from the shoulder to the upper limb, and only stretching and pulling the shoulder.

In order to enable the upper limb to hover in the lifting process, a plurality of collision beads 10 are fixed on the limiting plate 8 along the circumferential direction of the output shaft of the speed reducer 3, and a plurality of round holes corresponding to the collision beads 10 are arranged on the rotating rod 5. When the motor 2 is powered off, under the action of the pressure spring, the collision bead 10 can be clamped in the round hole on the rotating rod 5 to prevent the rotating rod 5 from continuing to rotate, and at the moment, the upper limb keeps hovering under the angle. When the motor 2 is electrified, the motor 2 overcomes the resistance of the collision bead 10, so that the rotating rod 5 continues to rotate.

In fig. 1, the motor 2 and the speed reducer 3 drive the upper limb to lift up, and this stretching in a specific direction cannot achieve the full stretching of the shoulder ligament and the shoulder joint. Based on the same principle as the above-described hovering mechanism, a turntable 4 is installed between the speed reducer 3 and the seatback 1, and the speed reducer 3 is rotatable relative to the seatback 1 by the turntable 4 and can be held relatively stationary with respect to the seatback 1 at a suitable angle.

Specifically, the speed reducer 3 is fixed to the turntable 4 by bolts. A rotating shaft (not shown) is provided on the seat back 1, and a plurality of collision beads 10 are provided in a circumferential array centering around the rotating shaft. A rotation shaft hole (not shown) corresponding to the rotation shaft is provided on the turntable 4, and a circular hole corresponding to the ball 10 is provided centering around the rotation shaft hole. The rear part of the spring 10 is provided with a compression spring (not shown in the figure), and the spring 10 can be clamped in the corresponding round hole under the action of the compression spring. When the unfolding direction of the upper limb is adjusted, only the speed reducer 3 and the rotary table 4 are required to be rotated, so that the collision bead 10 is clamped in the other round hole. Thus, the upper limb can be changed in the unfolding direction, for example, the upper limb can be unfolded and stretched in the horizontal direction by rotating the speed reducer 3 by 90 degrees.

In order to avoid damage to the shoulder joint caused by excessive lifting of the rotating rod 5, as shown in fig. 2, a rotation angle limiting structure is arranged between the rotating rod 5 and the speed reducer 3. The rotation angle limiting structure consists of two parts, one part is a flanging stop block 9 arranged on the rotating rod 5, the other part is a limiting plate 8 fixed on the rotating disc 4, and when the rotating rod 5 rotates upwards to a certain angle, the limiting plate 8 contacts with the flanging stop block 9 to prevent the rotating rod 5 from continuing to rotate.

It should be noted that the motion of the motor 2 may be controlled by a remote controller or may be automatically controlled by programming. Because the stretching of the shoulders is realized by electric or program control, the physical strength of people is not consumed basically, so that the people who are tired in work can comprehensively and automatically stretch the shoulders by sitting on the chair, and the chair is really enjoyment with health care effect.

The parts not described in detail are prior art. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
