[0029] The leg plates and supporting legs can be rotated under the action of the hinges when not in use, thereby realizing the folding of the load-bearing components, reducing the space occupied by the entire cervical traction shoulder relaxation chair when not in use, and improving its storage convenience.

[0030] The shoulder release mechanism 7 includes a first power assembly and a first movable assembly. The first power assembly is arranged in the mounting housing 2. The first movable assembly is arranged on both sides of the mounting housing 2 in the width direction and the first movable assembly is connected to the first power assembly.

[0031] The first power assembly includes a power motor 71, a movable rack 74, a first rotating gear 75, and a second rotating gear 76; the power motor 71 is fixedly connected in the mounting shell 2, and the output shaft of the power motor 71 is fixedly connected to one end of the crank 72, and the other end of the crank 72 is pin-connected to one end of the connecting rod 73, and the other end of the connecting rod 73 is pin-connected to the middle part of the movable rack 74; the first rotating gear 75 and the second rotating gear 76 are symmetrically arranged in the mounting shell 2 and the first rotating gear 75 and the second rotating gear 76 are rotatably connected to the mounting shell 2, the movable rack 74 is arranged between the first rotating gear 75 and the second rotating gear 76 and the teeth arranged on both sides of the movable rack 74 are respectively meshed with the teeth of the first rotating gear 75 and the second rotating gear 76, and the first rotating gear 75 and the second rotating gear 76 are transmission-connected to the first movable assembly.

[0033] When performing shoulder loosening movements, people only need to place their two arms on the arc placement plates respectively, and then start the power motor to work. Under the action of the crank and the connecting rod, the power motor converts the rotational movement of the power motor into the reciprocating movement of the movable rack. When the movable rack moves back and forth between the first rotating gear and the second rotating gear, it will drive the first rotating gear and the second rotating gear to perform reciprocating rotation at a certain angle, thereby driving the driven gears in the two shell parts and the rotating disks at the top of the two shell parts to rotate. When the rotating disk rotates, the two arc placement plates respectively drive people's two arms to perform rotational stretching movements, thereby achieving a loosening and massaging effect on the arms and shoulders.

[0034] The cervical traction mechanism 8 includes a second movable component, which is connected to one end of the mounting shell 2 in the length direction. A second power component is provided at the bottom of the second movable component and the second movable component is driven to slide by the second power component; a cervical limiting component and a third power component are provided at the top of the second movable component. The third power component is connected to the cervical limiting component and drives the cervical limiting component to move.

[0035] The second movable component includes a fixed shell 81, a movable shell 82, and a cover plate 83.

The two sides of the bottom end of the cover plate 83 cover the two sides of the movable shell 82 and the two sides of the fixed shell 81 to improve safety and aesthetics; the second power component is arranged in the fixed shell 81, the third power component is arranged in the movable shell 82, and the cervical vertebra limiting component is arranged on the outside of the movable shell 82 and is connected to the third power component.

[0036] The second power assembly includes a first traction motor 85 and a movable part 88. The first traction motor 85 is fixedly connected to the bottom end of the fixed shell 81. The movable part 88 is located in the fixed shell 81 and can slide along the length direction of the mounting shell 2. The top of the movable part 88 is fixedly connected to the movable shell 82. A fixed pulley 87 is provided on one side of the movable part 88. The fixed pulley 87 is connected to the first traction motor 85 through a first pulling rope 86. The other side of the movable part 88 is connected to a connecting ear 89 fixedly connected to the side wall of the fixed shell 81 through a first spring 810.

[0037] When people lie on the carrying assembly, their heads are located at the cover plate position and the back of their necks are located on the traction frame. During the traction action, the first traction motor drives the movable part to move toward the side away from the mounting shell, and the movable shell, the cover plate, the traction frame and the head placed on the cover plate all move toward the side away from the mounting shell along with the movable part, thereby achieving a cervical vertebra traction effect; after the traction, the first traction motor stops working, and the movable part drives the movable shell, the cover plate and the traction frame to reset under the action of the first spring; after resetting, the first traction motor works again, and repeats this reciprocating cycle to achieve a reciprocating traction and massage effect on people's cervical vertebrae.

[0038] The cervical vertebra limiting assembly includes two first transmission rods 811 symmetrically arranged on both sides of the movable shell 82 in the width direction, and two second transmission rods 812 symmetrically arranged on both sides of the movable shell 82 in the width direction. One end of the first transmission rod 811 is fixedly connected to the third movable assembly, and the other end of the first transmission rod 811 is bent upward and the end of the end is pin-connected to the end of the corresponding second transmission rod 812. The other ends of the two second transmission rods 812 are pin-connected to the limiting member 813 arranged in an arc shape; support members 814 are fixedly connected to the side walls on both sides of the width direction of the movable shell 82, and the support member 814 is located between the first transmission rod 811 and the second transmission rod 812 and close to the bent end of the first transmission rod 811;

[0039] The side of the support member 814 close to the movable shell 82 is configured as an arc end structure 8141, and the side of the support member 814 away from the movable shell 82 is configured as a baffle structure 8142;

[0040] When the first transmission rod 811 rotates downward, the second transmission rod 812 rotates with the support member 814 as the fulcrum under the obstruction of the support member 814. At this time, the second transmission rod 812 is located on the inner side of the baffle structure 8142 of the support member 814 and contacts the arc end 8141 structure of the support member 814, so that the rotation movement of the second transmission rod 812 is smoother. The rotation movement of the two second transmission rods 812 is used to enable the limit member 813 to realize rotation movement.

[0041] In order to prevent the head from escaping from the traction frame during traction and ensure the traction effect on the head, the utility model uses a cervical vertebra limiting component to position the head before the traction action; before the traction action is performed, the cervical vertebra limiting component is used to limit the position of the person's chin to improve the traction effect of the cervical vertebra traction mechanism on the head.

[0042] When limiting the position of the head, the third movable component drives the first transmission rod to rotate clockwise, the curved end of the first transmission rod rotates downward and drives one end of the second transmission rod to move downward, and the second transmission rod is hindered by the support member when moving downward and rotates along the arc end structure of the support member, so that the limit member rotates clockwise and is finally mounted under the chin of the person; when the second power component drives the movable shell to slide, the limit member pulls the person's chin and the traction frame pulls the back of the person's neck to move together with the movable shell, thereby achieving a traction effect on the position of the person's cervical spine; after the traction is completed, people only need to push the limit member upward, and the limit member and the first transmission rod can reverse and return to their original position under the action of gravity of the second transmission rod, without causing any hindrance to people's actions such as getting up.

[0043] The third movable component includes a second traction motor 815, a movable pulley 817, a positioning member 821, a traction seat 819, a second spring 822, a rotating shaft 823, a second traction rope 816, and a third traction rope 820; the second traction motor 815 and the positioning member 821 are fixedly connected to the bottom end of the movable shell 82, the traction seat 819 is located between the positioning member 821 and the second traction motor 815, and the traction seat 819 is connected to the positioning member 821 through the second spring 822, a movable pulley 817 is provided between the traction seat 819 and the second traction motor 815, and the fixed end of the movable pulley 817 is connected to the second traction motor 815 through the second traction rope 816; the rotating shaft 823 The axial direction is consistent with the width direction of the movable shell 82, and a power wheel 818 is fixedly sleeved in the middle of the rotating shaft 823. The two ends of the rotating shaft 823 are rotatably connected to the side walls of the movable shell 82, and the two ends of the rotating shaft 823 are fixedly connected to one end of the two first transmission rods 811 after passing through the side walls of the movable shell 82; the traction seat 819 is connected to one end of the third traction rope 820 away from the end of the second spring 822, and the other end of the third traction rope 820 is guided by the movable pulley 817 and then wound around the outside of the power wheel 818. The second spring 822 uses a certain pre-tightening force to prevent the second traction rope 816 and the third traction rope 820 from being in a relaxed state and affecting the pulling effect on the power wheel 818.

[0044] When the cervical vertebra limiting assembly is in motion, it is only necessary to make the second traction motor pull the movable pulley to move, and the movable pulley drives the third traction rope to pull the power wheel and the rotating shaft to rotate clockwise, so that the rotating shaft can transmit power to the first transmission rod. At this time, the second spring is in a stretched state; when the cervical vertebra limiting assembly is restored to its original position, the second transmission rod will drive the rotating shaft and the power wheel to rotate counterclockwise, and re-wind the third traction rope around the outside of the power wheel, so as to facilitate the next implementation of the cervical vertebra limiting assembly.

[0045] The utility model is designed to arrange a bearing assembly on the frame and a cervical vertebra traction mechanism at one end of the bearing assembly, so that when performing cervical vertebra traction operation, people can lie on the bearing assembly and perform cervical vertebra traction operation through the cervical vertebra traction mechanism, and the entire operation process is performed in a sleeping position, which improves the comfort of cervical vertebra traction operation; at the same time, the design of the shoulder relaxation mechanism is provided on the frame, so that when people lie on the bearing assembly in a sleeping position, they can place their arms on the shoulder relaxation mechanism, and the shoulder position of people can be moved by the rotation action of the shoulder relaxation mechanism, thereby achieving a massage effect on the shoulder position of people; compared with the traditional cervical vertebra traction chair, the utility model is more comprehensive in function and effectively improves the use effect of the cervical vertebra traction chair;

[0046] On the other hand, the operation of the cervical traction mechanism and the shoulder relaxation mechanism in the present invention are automatically realized by using a motor as power, and no human participation is required. People only need to lie on the load-bearing component to achieve the cervical traction and shoulder relaxation massage effects, making the entire active massage process more comfortable, further improving the use effect of the present invention.
