DETAILED DESCRIPTION

[0031] See also Figure 1In an embodiment of the present invention, a health therapy device includes a U-shaped plate 1, and the outer walls of both ends of the U-shaped plate 1 are sleeved with a shell 2. The shell 2 is provided with a cavity 8 in the middle of a side away from the U-shaped plate 1, and symmetrical connecting rods 6 are rotatably connected in the cavity 8. The symmetrical connecting rods 6 located in the same plane are commonly fixedly connected with a support plate 3. An adjustment mechanism for adjusting the rotation angle of the connecting rod 6 is provided in the middle of a side of the shell 2 away from the support plate 3. When the end of the adjustment mechanism away from the shell 2 moves horizontally toward the direction of the support plate 3, the symmetrical support plate 3 will rotate in a direction away from the center position of the shell 2.

[0032] See also Figure 2 The end of the connecting rod 6 away from the support plate 3 is fixedly connected to a toothed ring 10, and the middle part of the toothed ring 10 is rotatably connected to a rotating rod 11. The two ends of the rotating rod 11 are fixedly connected to the inner cavity side walls of the cavity 8. The middle part of the side of the connecting rod 6 away from the support plate 3 is fixedly connected to an arc block 7. The side of the inner cavity of the cavity 8 away from the support plate 3 is provided with an arc groove 9 used to cooperate with the arc block 7. The outer wall of the arc block 7 away from the connecting rod 6 is slidably connected to the cavity 8. The end of the arc block 7 away from the connecting rod 6 is elastically connected to the inner cavity side wall of the cavity 8 through a spring. The traction force of the spring on the arc block 7 and the sliding cooperation between the arc block 7 and the cavity 8 , so that the arc block 7 can be pulled to slide in the cavity 8 to drive the connecting rod 6 to rotate around the rotating rod 11, thereby driving the support plate 3 to rotate. In this way, when the device is worn, the support plate 3 that rotates upward and downward respectively will fit the user's chin and chest, thereby supporting the position of the user's head, thereby reducing the cervical pain caused by the user's long-term bowing of the head during daily work and using a mobile phone, and the possibility of neck extension. Through the support of the chin by the symmetrical support plate 3, the user's neck can maintain a healthy posture, thereby reducing damage to the cervical joints.

[0033] See also Figure 3 and Figure 8 A slide groove 12 used to cooperate with the end of the U-shaped plate 1 is opened on the side of the shell 2 away from the connecting rod 6, and the end of the U-shaped plate 1 is slidably connected to the slide groove 12. A plurality of limiting grooves 13 are opened on the upper and lower sides of the inner cavity of the slide groove 12. A limiting rod 14 used to cooperate with the limiting groove 13 is set in the middle of the upper and lower ends of the U-shaped plate 1. One end of the limiting rod 14 away from the limiting groove 13 is elastically connected to the U-shaped plate 1, and one end of the limiting rod 14 away from the U-shaped plate 1 is snap-connected with the limiting groove 13. Through the cooperation of the limiting groove 13 and the limiting rod 14, an elastic limiting effect is achieved between the U-shaped plate 1 and the shell 2. By pulling the U-shaped plate 1 to make the U-shaped plate 1 and the shell 2 move relative to each other, the distance between the shell 2 and the U-shaped plate 1 can be adjusted, which can be convenient for wearing and can also be used by users with different neck sizes.

[0034] See also Figure 5-Figure 7 The adjustment mechanism includes a knob 16, one end of the knob 16 close to the casing 2 is rotatably connected to the side wall of the casing 2, and a ring 19 is rotatably connected to the outer wall of the knob 16 close to the casing 2. The upper and lower sides of the ring 19 are fixedly connected to a fixing rod 20, and the end of the fixing rod 20 away from the ring 19 is fixedly connected to the side wall of the casing 2. The ring 19 provides support for the knob 16, so that the knob 16 can be more stable during the rotation process. The knob 16 is in the middle of the side away from the casing 2. The push rod 18 is slidably connected to the middle of the end of the push rod 18 away from the sleeve 2, and the moving rod 23 is fixedly connected to the middle of the end of the moving rod 23 away from the push rod 18. The balance rod 24 is slidably connected to the inner cavity side wall of the cavity 8. The middle of the moving rod 23 is provided with a moving groove 28 for matching with the balance rod 24. The outer wall of the balance rod 24 is slidably connected to the moving groove 28. Through the sliding cooperation between the balance rod 24 and the moving groove 28, it can be The movable rod 23 is made more stable during horizontal movement, and the balance rod 24 will limit and guide the movable rod 23, so that the movable rod 23 can only move in the horizontal direction. The end of the movable rod 23 away from the push rod 18 is elastically connected to the inner cavity side wall of the cavity 8 by a spring, and the spring is sleeved on the outer wall of the movable rod 23. The movable rod 23 is located between the symmetrical toothed rings 10, and a symmetrical fixing block 26 is fixedly connected to the side of the outer wall of the movable rod 23 close to the balance rod 24. The symmetrical fixing blocks 26 are respectively engaged with the symmetrical toothed rings 10, thereby limiting and fixing the toothed rings 10, thereby limiting and fixing the position of the support plate 3, and a symmetrical positioning block 25 is elastically connected to the side of the outer wall of the movable rod 23 close to the push rod 18. The vertical plane where the center position of the positioning block 25 is located coincides with the vertical plane where the center position of the fixing block 26 is located, and the vertical height from the end of the fixing block 26 to the side wall of the movable rod 23 is greater than the vertical height from the end of the positioning block 25 to the side wall of the movable rod 23.

[0035] When the angle of the support plate 3 needs to be adjusted, the button 17 is pressed to push the push rod 18 to move horizontally. The push rod 18 will push the moving rod 23 to move horizontally, thereby driving the fixing block 26 and the positioning block 25 to move horizontally, so that the fixing block 26 is separated from the gear ring 10 and loses its limiting effect on the gear ring 10. At this time, under the action of elastic force, the connecting rod 6 will be pulled to rotate through the arc block 7, thereby driving the support plate 3 to rotate. During the rotation of the gear ring 10, the teeth of the gear ring 10 will contact the end of the positioning block 25 away from the moving rod 23, and the positioning block 25 is elastically connected to the moving rod 23 so that it will not affect the rotation of the gear ring 10. When the gear ring 10 rotates, it will squeeze the positioning block 25 to make it close to the position of the moving rod 23, and the positioning block 25 will continue to move away from the moving rod 23 under the action of the elastic force. This allows the user to clearly feel the sense of frustration, making it easier to determine whether the positioning block 25 is between two adjacent teeth on the outer wall of the gear ring 10, thereby facilitating the fixing block 26 to reset and limit and fix the gear ring 10 again. Because the center positions of the positioning block 25 and the fixing block 26 coincide, when the positioning block 25 is located between two adjacent teeth on the outer wall of the gear ring 10, it means that the fixing block 26 will also be between two adjacent teeth on the outer wall of the gear ring 10 after resetting, thereby facilitating the fixing block 26 to limit the rotated gear ring 10, thereby fixing the angle of the rotated support plate 3. After adjusting the angle of the support plate 3, no pressure is applied to the button 17, and the movable rod 23 is pushed to reset by the elastic force, thereby driving the button 17 and the push rod 18 to reset.

[0036] See also Figure 4A winding drum 21 is fixedly connected to the middle of one end of the knob 16 away from the button 17, and the winding drum 21 is rotatably connected to the side wall of the casing 2. A symmetrical protective pad 15 is fixedly connected to the side of the U-shaped plate 1 away from the casing 2. A mounting cavity is provided in the middle of the U-shaped plate 1 near the protective pad 15. A symmetrical connecting plate 30 is slidably connected to the bottom of the inner cavity of the mounting cavity. The symmetrical connecting plates 30 are directly and commonly fixedly connected to symmetrical guide plates 29. A traction rope 31 is wound around the outer wall of the winding drum 21. The end of the traction rope 31 away from the winding drum 21 is fixedly connected to the middle of the connecting plate 30 near the casing 2. A second rope groove 33 is provided in the middle of the inner cavity of the slide groove 12 near the button 17. A symmetrical first rope groove 32 is provided in the middle of the side wall of the U-shaped plate 1. The second rope groove 33 is connected to the first rope groove 33. A rope groove 32 is located in the same horizontal plane, and the second rope groove 33 is connected to the first rope groove 32. The end of the traction rope 31 away from the winding drum 21 passes through the second rope groove 33 and the first rope groove 32 in sequence and is connected to the connecting plate 30. By turning the knob 16 to drive the winding drum 21 to rotate, the traction rope 31 can be continuously wound around the outer wall of the winding drum 21, so that the connecting plate 30 is pulled by the traction rope 31 to drive the guide plate 29 to move in the installation cavity. The connecting plate 30 is driven to move by the traction rope 31. When relative movement occurs between the casing 2 and the U-shaped plate 1, the first rope groove 32 and the second rope groove 33 will also move relative to each other. The traction rope 31 can adapt to the relative movement of the casing 2 and the U-shaped plate 1 while still driving the connecting plate 30 to move in the installation cavity.

[0037] See also Fig. 9 The end of the winding tube 21 away from the knob 16 is fixedly connected with a gear 22, and the gear 22 and the knob 16 are both slidably connected with the push rod 18. The diameter of the gear 22 is larger than the diameter of the winding tube 21. An elastic block 27 is arranged above the gear 22. The elastic block 27 is "L"-shaped. The upper part of the elastic block 27 is fixedly connected to the side wall of the inner cavity of the cavity 8 close to the knob 16, and the lower part of the elastic block 27 is engaged with the gear 22. That is, when the gear 22 is rotated with force, the elastic block 27 will be deformed by force. After stopping the rotation, the elastic block 27 will be reset due to the elastic force, thereby limiting and fixing the position of the gear 22 again.

[0038] See also Fig.10A servo motor 42 is fixedly connected to the middle of the inner cavity of the installation cavity, and a driving rod 43 is fixedly connected to the output end of the servo motor 42. A circular plate 40 is slidably connected to the outer wall of the driving rod 43. A plurality of supporting rods 41 are fixedly connected to the side of the circular plate 40 away from the servo motor 42. The driving rod 43 is driven to rotate by the servo motor 42, thereby driving the circular plate 40 and the supporting rod 41 to rotate, thereby achieving the effect of massaging the shoulder and neck muscles to relieve muscle soreness. In the process of massaging and relaxing the muscles by rotating the circular plate 40 and the supporting rod 41, the user will continue to feel muscle soreness. If the neck position of the user is not restricted, the user may experience muscle pain during the massage process. The user will unconsciously extend the neck forward, thereby reducing the contact between the muscles and the support rod 41 to relieve the pain, which will lead to a poor effect of massage therapy and fail to achieve the purpose of relaxing the muscles. The symmetrical support plate 3 supports the neck, which can prevent the user from unconsciously extending the neck due to pain, thereby improving the massage therapy effect of the support rod 41. In addition, during the massage process, while the support rod 41 applies force to the neck muscles, it will also be subjected to a reaction force, which causes the reaction force received by the support rod 41 to be transmitted to the U-shaped plate 1, making it impossible for the support rod 41 to fit closely with the muscles, thereby resulting in a poor massage effect. The symmetrical support plate 3 supports the neck, which can prevent the U-shaped plate 1 from moving due to the reaction force.

[0039] See also Fig.11A mounting plate 37 is fitted on one side of the circular plate 40 away from the support rod 41, and sliders 38 are fixedly connected to both ends of the mounting plate 37 on one side close to the connecting plate 30.
