[0013] See also Figure 1-11 , the present invention provides a technical solution: A massage chair capable of adjusting the sitting and lying angle of a human body, comprising a base 2 and a chair frame 1, wherein the chair frame 1 is used for a user to sit on; the base 2 is provided with shaft holes on the left and right sides relative to the user's seat, and the chair frame 1 is hinged to the shaft holes of the base 2 through a rotating shaft, so that the chair frame 1 can rotate relative to the base 2 with the shaft holes and the axis as the center, thereby changing the sitting and lying angle of the user. It also comprises a control mechanism 3, a positioning baffle 5 and a plug-in mechanism 4; Figure 3 As shown, one end of the control mechanism 3 is arranged at a position that can be touched by the user's hand, such as the two sides of the seat; the other side of the control mechanism 3 is arranged to connect to the plug mechanism 4, so that the control mechanism 3 controls the movement of the plug mechanism 4. One end of the positioning baffle 5 is fixed to the rotating shaft or the chair frame 1, and the other end of the positioning baffle 5 is provided with at least two spaced positioning strips 51, and the positioning strips 51 are spaced from each other in a circular area centered on the rotating shaft and are all arranged radially, such as Figure 6 As shown, the positioning bars 51 are arranged evenly at intervals, and there are positioning grooves of equal width between each positioning bar 51. The plug-in mechanism 4 is arranged on the base 2 and corresponding to the positioning bars 51. The plug-in mechanism 4 includes a plug 41. The control mechanism 3 controls the plug 41 to reciprocate so as to be plugged in or out of the different positioning bars 51. Figure 5 and Figure 6 As shown in FIG. 1 , the control mechanism 3 causes the plug 41 to retract and disengage from the positioning strip 51. Figure 7 and Figure 8 The control mechanism 3 shown in the figure releases the plug 41 and plugs it into the positioning bar 51 .
[0014] The control mechanism 3 controls the plug-in mechanism 4, and controls the plug-in and disengagement of the plug 41 and the positioning strip 51. When the plug 41 is disengaged from the positioning strip 51, the user can rotate the chair frame 1 around the shaft hole relative to the base 2 to select a suitable sitting or lying angle; when a suitable sitting or lying angle is selected, the user controls the control mechanism 3 to plug the plug 41 and the positioning strip 51, and the angle is fixed. One end of the positioning baffle 5 is fixed on the rotating shaft or the chair frame 1, and a plurality of positioning strips 51 are provided. The positioning strips 51 are arranged at intervals and are arranged in a circular area centered on the rotating shaft, providing gears for the chair frame 1 when the angle changes. The plug 41 is plugged into different positioning strips 51, which realizes the angle change of the chair frame 1 and the base 2. The plug 41 and the positioning strip 51 have many matching angle gears, simple structure, high stability, and convenient adjustment.
[0015] like Figure 3 As shown, the base 2 is provided with a backrest, and the backrest is provided with a massage movement 66. The massage movement 6 can reciprocate and massage along the user's head, neck, shoulders, back and waist in sequence.
[0016] like Figure 5-8 As shown, the number of the positioning baffles 5 is two, which are symmetrically arranged on both sides of the chair frame 1, and the plug-in mechanism 4 is arranged at the middle position of the base 2 relative to the seat of the chair frame 1, and the number is also two, that is, one positioning baffle 5 corresponds to one plug-in mechanism 4. The positioning baffles 5 are arranged on both sides of the chair frame 1 to make the chair frame 1 more stable when the angle changes, and the left and right sides are evenly stressed, and the problem of the chair frame 1 and the base 2 tilting at an angle will not occur.
[0017] As shown in Figures 4, 5 and 7, the control mechanism 3 includes an adjustment handle 31, a connecting line 32, a positioning shaft 33 and a transmission piece 34. The middle part of the transmission piece 34 is hinged on the positioning shaft 33, and the positioning shaft 33 is fixedly connected to the base 2. The adjustment handle 31 is connected to one end of the transmission piece 34 through the connecting line 32, and the other end of the transmission piece 34 is connected to the plug 41 of the plug-in mechanism 4 to drive the plug-in connector to reciprocate. When the adjustment handle 31 pulls the transmission piece 34 through the connecting line 32, the transmission piece 34 rotates around the positioning shaft 33, so that the plug 41 is away from the positioning strip 51, so that the chair frame 1 and the base 2 can change their angles. When the user releases the adjustment handle 31 and releases the transmission plate 34 through the connecting line 32, the transmission plate 34 returns to its original position around the positioning axis 33, so that the plug 41 is close to the positioning bar 51, and the plug 41 is connected with the positioning bar 51, so that the chair frame 1 and the base 2 can be fixed at an angle.
[0018] As shown in Figures 4, 5 and 7, there are two transmission plates 34, which are respectively arranged relative to the two plug-in mechanisms 4, that is, one transmission plate 34 corresponds to one plug-in mechanism 4. This solution can make the reciprocating motion of the plug-in mechanism 4 more controllable, and there will be no problem of the plug 41 being out of control or the plug 41 being derailed from the positioning bar 51.
[0019] like Figure 4 As shown, the transmission sheet 34 is provided with a torsion spring 341, the center of which is hinged to the positioning shaft 33, one end of the torsion spring 341 is connected to the base 2, and the other end of the torsion spring 341 is connected to the transmission sheet 34. The torsion spring 341 can make the positioning sheet rotate around the positioning shaft 33 when the force of the connecting line 32 is applied, and the positioning sheet can be restored to the original position when the force of the connecting line 32 is not applied. That is, when the connecting line 32 applies a pulling force to the transmission sheet 34, the transmission sheet 34 rotates around the positioning shaft 33, driving the plug 41 away from the positioning bar 51; when the connecting line 32 does not apply a pulling force to the transmission sheet 34, the transmission sheet 34 returns to its original position around the positioning shaft 33, driving the plug 41 to be plugged into the positioning bar 51.
[0020] like Figure 5 and Figure 7As shown, the plug-in mechanism 4 further includes a sheath that partially covers the plug 41, and a first opening is provided at one end of the sheath, through which the plug 41 protrudes and is plugged into the positioning bar 51; a second opening is provided at a side of the sheath close to the control mechanism 3, and the transmission sheet 34 is connected to the plug 41 through the second opening. The sheath can protect the reciprocating motion position of the plug 41 and prevent the motion trajectory from changing, so that the plug 41 and the positioning bar 51 are plugged in and out with high accuracy and high stability of angle adjustment.
[0021] A spring is provided inside the other end of the sheath relative to the first opening. The spring generates a force on the plug 41 . The force can further make the plug 41 approach the positioning strip 51 to form a plug-in relationship, thereby further improving the plug-in stability between the plug 41 and the positioning strip 51 .
[0022] like Fig.11 and 12 As shown, a limiting column 7 is provided at the rear of the base 2, and the seat of the chair frame 1 abuts against the limiting column 7. The angle between the seat of the chair frame 1 and the base 2 is the largest. When the seat support of the chair frame 1 abuts against the limiting column 7, the angle of the chair frame 1 no longer changes. This ensures that the angle adjustment setting of the chair frame 1 is within a certain range, and does not cause excessive adjustment backwards to cause the user to lean back in danger. The chair frame 1 and the base 2 are protected and no large impact force occurs, thereby increasing the service life of the massage chair.
[0023] like Fig.11 and 12 As shown, a buffer is provided at the front of the base 2, and the seat of the chair frame 1 abuts against the buffer column 8. The angle between the seat of the chair frame 1 and the base 2 is the smallest. When the seat support of the chair frame 1 abuts against the buffer column 8, the angle of the chair frame 1 no longer changes. This ensures that the angle adjustment setting of the chair frame 1 is within a certain range, and does not cause excessive forward adjustment to cause the user to lean forward in danger. The chair frame 1 and the base 2 are protected and no large impact force occurs, thereby increasing the service life of the massage chair.
[0024] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
