The first supporting body 2 is horizontally arranged on the support 1 and forms a first end surface for supporting buttocks; the first support body 2 can be made of hard material or soft material, and the structure can be designed to fit the human hip structure, but because of the structure, the first support body needs to provide a supporting force during movement, and is preferably made of hard material, such as hard board, and the outer part can be covered with plus material. The first support body 2 can be adjusted in height by an adjusting structure arranged on the support 1 so as to be suitable for users with different body shapes.
The second supporting body 3 is obliquely arranged on the support 1 relative to the horizontal plane and forms a second end surface for supporting the back; the second support body 3 can be made of hard material or soft material, and the structure can be designed to fit the back structure of human body, but because the structure needs to provide a supporting force during exercise, preferably hard material, such as hard board, the outside can be covered with fabric, so that the exercise is a half-leaning sitting posture, and the second support body is safe and easy to provide the supporting force.
The key point of the present invention is that the back stretching device comprises two back stretching units 4 respectively disposed at two sides of the second supporting body 3, each back stretching unit 4 comprises a transfer structure 41, a stretching rod 42 and a counterweight structure 43;
one end of the switching structure 41 is hinged to the support 1, and the other end is hinged to the stretching rod 42, so that the free end of the stretching rod 42 can drive the switching structure 41 to rotate under the action of external force, and because the switching structure 41 adopts a hinged connection mode of two ends, the free end of the stretching rod 42 can have a very large movement range, and the provided arm has a large movement range without being limited to the movement range; the support is provided with a supporting structure 7, the supporting structure 7 is used for providing a first supporting surface, one end of the switching structure 41 is fixed on the first supporting surface, and the rotating surfaces of the switching structure 41 and the stretching rod 42 are parallel to or coincident with the first supporting surface. In this way, the movement position of the whole movement component is concentrated, but the degree of freedom is high, since the arm of the human body is arranged at the position, the bending and the extension of the arm can be ensured not to be limited only by making the first supporting surface and the second end surface as perpendicular as possible, preferably between 88 and 92 degrees, and the arm can be prevented from being strained by the lateral force at the same time, the supporting structure 7 comprises an inclined supporting body 72 and a supporting frame 71, the first supporting surface is arranged on the supporting frame 71, and the inclined supporting body 72 is fixed on the supporting frame 71 and is perpendicular to the first supporting surface.
The end of the stretch rod 42 is provided with a grip portion that is rotatably connected to the end of the stretch rod.

A first limit structure 5 is fixed on the stretching rod 42, and the first limit structure 5 comprises a limit rod 51 and a first anti-collision layer 52 fixedly arranged on the limit rod 51; when the stretching rod 42 rotates relative to the adapting structure 41 along a rotating direction and the first anti-collision layer 52 collides with the adapting structure 41, the first limiting structure 5 limits the rotation of the stretching rod 42 relative to the adapting structure 41 along the rotating direction. The first anti-collision layer 52 may have a cylindrical structure made of rubber material, and the limiting rod 51 is extended from the stretching rod 42 as shown in the figure, and the extending direction of the limiting rod is staggered with the extending direction of the main body of the stretching rod 42, so that the first anti-collision layer 52 can more easily contact the adapting structure 41 during rotation, and meanwhile, the first anti-collision layer 52 is made of flexible material, so that collision damage and noise cannot occur.
Be fixed with second limit structure 6 on the switching structure 41, second limit structure 6 includes second anticollision layer, switching structure 41 is relative along a direction of rotation support 1 rotates and makes the second anticollision layer with when switching structure 41 contradicts, second limit structure 6 restriction switching structure 41 for the rotation of support 1. The second anti-collision layer is arranged to prevent the adapting structure 41 from colliding with the support 1 to cause damage, and simultaneously limit the rotation angle of the adapting structure 41, so that the adapting structure 41 keeps the counterweight structure 43 in a vertical state under a static condition.
when the cushion compression element 80 is compressed, the expansion working medium valve 84 is closed to isolate the first working medium cavity 82 and the second working medium cavity 83;
when the damper compression element 80 is released, the expansion chamber valve 84 is opened to communicate the first chamber 82 and the second chamber 83. Firstly, in the process of movement, hands can keep the buffer pressing piece 80 in a pressing state, at the moment, the first working medium cavity 82 is controlled to be in an independent internal pressure state, the buffer pressing piece 80 can be freely lifted and released, once people get rid of discomfort in the process of movement, the buffer pressing piece 80 can be released in the first reaction, if no buffer exists, large impact force can be generated, and potential safety hazards are caused, so when the buffer pressing piece 80 is released, the compressed working medium can enter the first working medium cavity 82, the linkage rod piece 81 can not continuously fall, a buffer effect can be achieved on the whole structure, and due to the gravity action of the counterweight 431, the released working medium can be slowly compressed back to the first working medium cavity 82, the operation is simple, reliable and easy to realize, it needs to be explained that the working medium in the second working medium cavity 83 can be compressed through the counterweight 431, the compression can also be carried out through a compressor, which is not described in detail, and the working medium can be a liquid working medium or a gaseous working medium.
Referring to fig. 5, the first working medium chamber 82 is provided with a first one-way hole 821 and communicates with the outside air through the first one-way hole 821, and the first one-way hole 821 blocks the working medium of the first working medium chamber 82 from flowing to the outside air through the first one-way hole 821, as a principle is as follows. Therefore, in the process of movement, the air pressure in the first working medium cavity 82 cannot be changed, the movement cannot be hindered, and in the process of expansion, the working medium cannot rush out of the outside, so that the movement is reasonable.
The bottom of the first working medium cavity 82 is provided with a second one-way hole 831 and is communicated with the second working medium cavity 83 through the second one-way hole 831, and the second one-way hole 831 blocks working medium of the second working medium cavity 83 from flowing to the first working medium cavity 82 through the second one-way hole 831. In the movement process, if more working media still exist in the first working medium cavity 82 at the moment and are not compressed, then at the moment, the air pressure is difficult to supplement because the external air flow rate is smaller than the air pressure generated by the descending movement of the linkage rod piston, so that the working media can be pressed into the second working medium cavity 83, and when the linkage rod piston ascends, due to the arrangement of the second one-way hole 831, the external air flow rate is smaller in time, the working media can not flow back, and the preparation is made for the next buffering.
The damper press 80 is configured as a button that generates a first signal to control the expansion valve 84 to close when pressed and a second signal to control the expansion valve 84 to open when released. The stop and the conduction of the expansion working medium valve 84 are controlled through the button, the response speed is high, and extra lines and mechanical structures are not needed.
The number of the buffer devices is two, and the two buffer devices are respectively arranged corresponding to the two back unfolding units 4.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
