Detailed Description
The invention is further described with reference to the accompanying drawings.
As shown in fig. 1-3, the lumbar muscle strain rehabilitation mechanism includes a base 1, an electric rod base 2, an electric push rod 3, a seat back 4, a meshing gear set 5, an eccentric wheel 6, a bracket 7, a slider connecting rod 8, a stretching armrest 9, a seat cushion 10, a seat bottom plate 11, a seat bottom frame 12, a vertical profile frame 13, a slide rail 14, a transverse profile frame 15, an electric push rod two 16 and a rotating disc 17.
The lumbar muscle strain rehabilitation mechanism comprises a seat base 1, wherein a seat bottom frame 12 is arranged on the seat base 1, a seat back 4 is movably connected to the seat bottom frame 12, and a back angle adjusting device is arranged on the seat back 4; a vertical section bar frame 15 is arranged on the seat base 1, and a transverse section bar frame 16 is movably connected to the upper end of the vertical section bar frame 15; a waist muscle stretching device is arranged on the transverse section bar frame 16; the seat is characterized in that a seat bottom plate 11 is arranged on the seat bottom frame 12, and a waist muscle twisting device is arranged on the seat bottom plate 11.
The back angle adjusting device comprises a first electric push rod 3 and an electric push rod base 2, wherein the first electric push rod 3 is movably arranged on the seat base 1 through the electric push rod base 2, and the top of the first electric push rod 3 is movably connected with the seat back 4. The seat back is connected through the hinge with the seat chassis, and the seat back can rotate, withstands the seat back when electric pole body extension and rotates, when the people sits on the chair, can lie passively and sit up, carries out the reciprocal rehabilitation training of waist belly muscle.
The waist muscle stretching device comprises a motor, a meshing gear set 5, an eccentric wheel 6, a slide block connecting rod 8 and a stretching handrail 9, wherein the motor, the meshing gear set 5 and the eccentric wheel 6 are all arranged on a bracket 7; the motor is connected with the meshing gear set 5 in a transmission mode, the meshing gear set 5 is connected with the eccentric wheel 6 in a transmission mode, one end of the sliding block connecting rod 8 is connected with the eccentric wheel 6, the other end of the sliding block connecting rod 8 is arranged on the transverse profile frame 15, and the stretching handrail 9 is arranged at the tail end of the sliding block connecting rod 8. The motor drives the meshing gear set to rotate, the eccentric wheel is driven to rotate after the gear meshing speed reduction, the eccentric wheel and the sliding block connecting rod form a crank sliding block mechanism so as to drive the stretching handrail to reciprocate, and a user holds the stretching handrail with two hands, so that the waist muscle can be stretched.
The lumbar muscle twisting device comprises a rotating disc 17 and a seat cushion 10, wherein the seat cushion 10 is arranged on the seat bottom plate 11 through the rotating disc 17, so that the seat cushion 10 can freely rotate on the seat bottom plate 11. When a person sits on the seat cushion, the seat cushion is connected with the rotating disc, and the user can actively twist the waist on the seat cushion, so that the waist muscles are stretched and relaxed.
An electric push rod II 16 is arranged on the vertical section bar frame 13, one end of the electric push rod II 16 is movably connected with the vertical section bar frame 13, and the other end of the electric push rod II 16 is movably connected with the transverse section bar frame 15. Vertical section bar frame is connected through articulated with horizontal section bar frame 15, and horizontal section bar frame can rotate, thereby horizontal section bar frame upwards rotates with whole superstructure two extensions, facilitates the use and gets into the seat, sits into the chair after the people and contracts electric putter two, makes superstructure descend, descends to suitable position until tensile handrail, and the person of facilitating the use can hold tensile handrail and take exercise.
The biggest subversion of the application relative to the common machine is that the position of mechanisms such as a motor, a speed reducer crank slide block and the like is selected and placed on the upper part of a user. The reason for this is that if we want to put the motor at the ground like a conventional machine, we need to complete the design of the mechanism with a bulky mechanism and more material, which is laborious and wasteful of material. Therefore, the design is completed by methods of intensity calculation, reliability estimation and the like on the scheme of mounting the motor, so that the whole machine looks simple and is not so heavy, and the originally required functions are realized. Secondly, the manufacturing material of the machine is saved.
Because the mechanism of upper portion is more, if fixed motionless, then the user need the head that lowers the entering, user-friendly nature just greatly reduced, to this problem, the solution that we chose is through the rising and the decline of electric putter structure control upper portion structure, lets the people can normally get into and walk out, has increased user comfort level. The electric push rod used by people can realize arbitrary extension and retraction within the stroke range through the controller. Thereby adjusting the height of the stretching push rod to adapt to people with different heights. The application range of the machine is increased.
