Description

Arc reciprocating swing mechanism and device

Technical Field

The invention belongs to the field of health-care equipment, and particularly relates to an arc-shaped reciprocating swinging mechanism and device.

Background

Research shows that (referring to the influence and mechanism progress of whole-body horizontal vibration training on the cardiovascular system, Chinese rehabilitation theory and practice, vol. 25, 4 th of 2019 in 4 months), whole-body vibration training can achieve the purposes of relaxing blood vessels, improving blood circulation, improving pulse pressure and the like, and is beneficial to the physical and mental health of users. The specific principle is as follows: whole body vibration-clapping phenomenon-increasing blood flow rate-increasing shearing force, stimulating endothelial cells-increasing NO content-acting as gas signal molecules-relaxing blood vessels.

Many solutions have been proposed in the prior art for horizontal and vertical vibrations, and the above-described mechanism is then used in healthcare facilities. The reason that the prior art does not combine horizontal and vertical motions is that the prior art has gone into an isolated direction of development, continuously increases the speed of horizontal vibration or continuously increases the speed of vertical vibration, and naturally, when a mechanism moves horizontally at a high speed, it is difficult to superpose a vertical motion at a high speed.

Disclosure of Invention

The invention aims to provide an arc-shaped reciprocating swing mechanism and device, which organically combine the movement on a vertical surface, thereby overcoming the defect that the prior art can only move horizontally or vertically independently.

In order to achieve the above object, the present invention provides an arc-shaped reciprocating swing mechanism, comprising: the bracket base is used as a bearing main body; the movable support is arranged on the support base, is movably connected with the support base and can swing back and forth relative to the support base, the swing path of the movable support is arc-shaped, and the head end and the tail end of the path are both higher than the middle position; the movable support is hinged to the lower end of the movable support, hinged positions of the upper end and the lower end of the transition support are located in the same vertical plane in a natural state, and the lowest end of the movable support passing through the movable support during swinging is a position with low self-height potential energy, and the lowest end of the movable support passing through the movable support is a position with high self-height potential energy passing through the movable support from head end to tail end. By adopting the scheme, the motion path of the movable support is high and low under the limitation, the lower end of the movable support is located at the lowest position under the natural state, the movable support is in a suspended state, the self balance is easily broken, the movable support starts to swing back and forth after external force is applied to convert power into high potential energy, and compared with a swing mode of the movable support with low height, the swing is more stable and silent because the power output does not need to overcome the gravitational potential energy of the movable support and the load.

As the improvement of the scheme, the bracket base comprises two clamping plates, the movable bracket comprises a stress plate, the two clamping plates are positioned on the outermost side, and the clamping plates, the transition bracket, the stress plate, the transition bracket and the clamping plate are sequentially distributed from one clamping plate as a starting point to the other clamping plate as a finishing point. By adopting the scheme, the structure is symmetrically distributed, and the mechanism is stressed uniformly and swings stably.

In other schemes, can set the atress board to two as required, and splint reduce a slice, and two atress boards are located the outside this moment to a atress board is as the starting point to another atress board as the terminal point, distributes in proper order and has atress board, transition support, splint, transition support and atress board. In other schemes, the single arc-shaped reciprocating swinging mechanism can be arranged in a unilateral layout without a symmetrical structure, for example, a clamping plate, a transition bracket and a stress plate are sequentially distributed; two arc reciprocating swing mechanisms are used as a group, and the two arc reciprocating swing mechanisms which are distributed on one side can be combined to be stressed symmetrically left and right.

As an improvement of the scheme, one rotating shaft is positioned at the upper end and penetrates through one clamping plate, one transition support, the stress plate, the other transition support and the other clamping plate, one rotating shaft is positioned at the lower end and penetrates through one transition support, the stress plate and the other transition support, an upper through hole with the diameter larger than that of the rotating shaft is formed in the upper end of the stress plate, and a lower through hole with the diameter equal to that of the rotating shaft is formed in the lower end of the stress plate. By adopting the scheme, the rotating shaft at the upper end is a whole, so that the uniform stress is easily ensured; correspondingly, the upper through hole of the stress plate has enough space to allow the movable support to swing (because the shaking amplitude is small, the gap between the upper through hole and the rotating shaft can be small).

In other schemes, the rotating shaft at the upper end can be split into two sections, and the stress plate does not need to be perforated. In this kind of embodiment, one splint have two-layer can hold the head and the tail both ends of pivot simultaneously (centre gripping transition support simultaneously), and another splint also have two-layer can hold the head and the tail both ends of pivot simultaneously (centre gripping transition support simultaneously), and the pivot that lies in the lower extreme needs to pass the downside of splint this time, because the pivot of lower extreme needs to rock, and the position that the corresponding splint were passed by the pivot of lower extreme has the perforation of great diameter.

As an improvement of the scheme, bearings are arranged between the two transition supports and the rotating shaft located at the upper end, bearings are arranged between the two transition supports and the rotating shaft located at the lower end, the head end and the tail end of the rotating shaft located at the upper end are locked by the two clamping plates respectively, and the middle section of the rotating shaft located at the lower end is locked by the stress plate.

By adopting the scheme, the movable support naturally attaches the state of vertical movement when moving horizontally, so that the whole body vibration is realized, the blood vessels are better relaxed, the blood circulation is improved, the pulse pressure is improved, the joint muscle movement is increased, the bone density is increased, and the respiration is promoted. When a user lies on the upper bed body, the movable support is subjected to higher pressure, and the balance point is located at the lowest position on the swing path because the movable support is in a suspended state, so that the motor and the transmission mechanism thereof can easily drive the upper bed body to swing.
