The invention aims to solve the problem of disease deterioration of patients suffering from waist diseases caused by bending, and utilizes the mutual coordination of the adjustable cylinder power-assisting unit and the spring power-assisting unit to achieve the effect of providing auxiliary support for the bending person.
Examples:
referring to the lumbar joint booster shown in fig. 1-4, the lumbar joint booster comprises an adjustable belt 1, wherein two sides of the adjustable belt 1 are respectively provided with a group of adjusting booster systems, each group of adjusting booster systems comprises an armpit support 2, a cylinder booster unit 3 and a spring booster unit 4, the positions of the cylinder booster unit 3 and the spring booster unit 4 can be adjusted on the adjustable belt 1, and the cylinder booster unit 3 and the spring booster unit 4 are both in shaft connection with the lower end of the armpit support 2 through rigid connecting rods; the armpit support 2, the cylinder power-assisted unit 3, the spring power-assisted unit 4 and the adjustable belt 1 form a triangular supporting structure with adjustable angles, when a user bends down, the cylinder power-assisted unit 3 provides upward supporting force, and the spring power-assisted unit 4 provides torque with opposite bending direction.

Referring to fig. 5, the cylinder power assisting unit 3 comprises a cylinder 5, a piston 6, a piston rod 7, two groups of one-way valves 8 and a release valve 9, wherein the piston 6 is arranged in the cylinder 5, the piston 5 is connected with the piston rod 7, the upper end of the piston rod 7 is connected with an axillary support 2 in a shaft way, a first air port and a second air port are respectively arranged at the upper end and the lower end (the upper cavity and the lower cavity of the cylinder 5) of the cylinder, an air passage pipeline is connected between the first air port and the second air port, the air passage pipeline at the side of the second air port is externally connected with the release valve 9, the air passage pipeline at the side of the first interface is externally connected with a group of one-way valves 8 which are led to the direction of the air passage pipeline from outside, and the middle section of the air passage pipeline is provided with a group of one-way valves 8 which are led to the direction of the second air port from the first air port.
The air path principle of the air cylinder booster unit 3 is as follows: when the user stands upright, the pressure of the upper cavity and the lower cavity of the air cylinder 5 is balanced; when a user starts to bend down, the pressure of the lower cavity of the air cylinder 5 is increased, the pressure of the upper cavity is reduced, the upward supporting force is given to the human body, and the larger the bending angle of the user is, the larger the supporting force is; when a user lifts up from the bending position, the pressure difference between the upper cavity and the lower cavity of the air cylinder 5 still supports the upper body of the person upwards, but the force is smaller and is just in line with the requirement of the human body; when the human body circulates and bends down, the pressure of the upper cavity of the air cylinder 5 is lower and lower, at the moment, air can be sucked by the air channel pipeline one-way valve 8 at the first interface side to supplement the air quantity of the upper cavity, the pressure of the lower cavity is gradually increased along with the increase of the circulation times, and when the pressure exceeds the regulating pressure of the air release valve, the air release valve 9 is opened to remove redundant air.
In order to adapt to the needs of patients with different weights/different disease parts, the elasticity of the spring body 12 and the pressure difference of the air cylinder 5 can be adjusted; the adjustment mode of the size of the spring body 12 is as follows: by adopting the principle of a ratchet mechanism, the function of adjusting the elastic force can be achieved by changing the angle between the spring body 12 and the spring connecting rod 10; the pressure difference of the cylinder 5 is regulated by opening and closing the check valve 8 and the air release valve 9.
The following are parameters of the cylinder assist unit 3 and the spring assist unit 4 in one embodiment:
cylinder stroke: 20-25 mm
Pressure calculation: the cylinder diameter is 6mm, and the volume of compressed gas is 565mm when the piston descends for 20mm 3
Pressure value at bending position: 0.07-0.1 MPa
Pressure in the bent position: 0.5-2 Kg

The mounting positions of the cylinder 5 and the fixed box clamp 13 are also adjustable; the specific adjustment mode is as follows: the adjustable belt 1 is provided with a plurality of groups of holes, the tail ends of the air cylinder 5 and the fixed box clamp 13 are respectively provided with a fixed part, and the air cylinder power assisting unit and the spring power assisting unit can be arranged in the holes at different positions of the adjustable belt 1 through the fixed parts.
The following describes the use of the invention:
referring to fig. 3, when the user is in the upright state, the cylinder power assisting unit 3 and the spring power assisting unit 4 are in a slight stress state, and the armpit support 2 is slightly lifted upwards to be attached to the armpits of the human body.
Referring to fig. 4, fig. 4 is a state diagram of a user when bending 45 degrees, the spring assisting unit 4 starts to bear force, and sends torque opposite to the bending direction to the user; simultaneously, the cylinder power assisting unit 3 provides upward supporting force for the upper part of the human body; when the human body bends down to reach the position shown in fig. 2, the pressure of the lower cavity of the air cylinder can reach 0.05 to 0.1Pa, and the maximum supporting force can reach 2Kg at the maximum time;
in contrast, when the human body is lifted from the bent-over state, the spring booster unit 4 and the cylinder booster unit 3 can boost the waist to a lifting force, thereby helping the user to easily stand up.
The foregoing description of the invention has been presented for purposes of illustration and description, and is not intended to be limiting.
