When the driving mechanism 7 is operated, the driving mechanism 7 can drive the chair body 1 to swing. An unlocking mechanism 5 is arranged on the n-type hollow column 2.

[0036] The unlocking mechanism 5 includes a movable frame 51, a cylinder 52, a trigger rod 53 and an elastic member 54, see Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the upper parts of the front and rear n-type hollow columns 2 are symmetrically and slidably connected with movable frames 51, which are located below the handrail 4. A cylinder 52 is installed at the bottom of the movable frame 51 by bolt connection. The n-type rack 401 slides through the cylinder 52, and the cylinder 52 is located in the n-type hollow column 2. When the cylinder 52 moves downward, the cylinder 52 can drive the trigger mechanism 6 to operate. The inner sides of the four movable frames 51 are fixed with trigger rods 53. The trigger rod 53 moves downward and contacts the driving mechanism 7. When the trigger rod 53 moves downward and contacts the driving mechanism 7, the trigger rod 53 can drive the driving mechanism 7 to operate. An elastic member 54 is connected between the inner side of the movable frame 51 and the inner side of the n-type hollow column 2.

[0037] The trigger mechanism 6 includes a magnetic block 61, a rotating frame 63, a hexagonal block 64, a connecting plate 65, a transmission assembly 66, a fixed shaft 67, a gear 68 and a torsion spring 69, see Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.11 and Fig.12As shown, the left and right sides of the n-shaped hollow columns 2 on the front and rear sides are symmetrically opened with a slot 62, the upper and lower sides of the slot 62 are wider, and the slot 62 is slidably connected with a hexagonal block 64, and a rotating frame 63 is fixedly connected between the inner ends of each two hexagonal blocks 64. A magnetic block 61 is fixedly connected to each rotating frame 63 symmetrically. When the driving mechanism 7 is unlocked, the magnetic block 61 can drive the driving mechanism 7 to operate. A fixed shaft 67 is fixedly connected between the upper parts of the front and rear side surfaces of the four cylinders 52, and a connecting plate 65 is fixedly mounted in the middle of the fixed shaft 67. The lower part of the connecting plate 65 is rotatably mounted in the middle of the rotating frame 63, and the fixed shaft 67 and the rotating frame 63 are fixedly connected. A transmission assembly 66 is symmetrically connected to the front and rear sides of the connecting plate 65 in a damped rotational manner. The transmission assembly 66 is located on the front and rear sides of the connecting plate 65. The transmission assembly 66 consists of two pulleys and a flat belt. One of the pulleys is rotatably mounted on a fixed shaft 67, and the other pulley is rotatably mounted on a rotating frame 63. The flat belt is wound between the two pulleys. Gears 68 are fixedly connected to the upper portions of the outer surfaces of the transmission assemblies 66 on the front and rear sides. The gears 68 move downward and mesh with the n-shaped rack 401. The gears 68 mesh with the telescopic rod 402. A torsion spring 69 is connected between the lower portion of the transmission assembly 66 and the inner side surface of the magnetic block 61. The torsion spring 69 is mounted on the rotating frame 63.

[0038] The driving mechanism 7 includes a magnet driving rod 71, an L-shaped groove rod 72 and a first spring 73, see Figure 3 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the lower parts of the left and right sides of the front and rear n-type hollow columns 2 are slidably connected with magnet driving rods 71. When the magnet driving rods 71 ​​move downward and contact the ground, the magnet driving rods 71 ​​can drive the chair body 1 to swing. The outer side surfaces of the front and rear n-type hollow columns 2 are symmetrically slidably connected with L-shaped groove rods 72. The inner ends of the four L-shaped groove rods 72 are respectively in contact with the inner sides of the four magnet driving rods 71. The L-shaped groove rods 72 can limit the magnet driving rods 71. The trigger rod 53 moves downward and contacts the L-shaped groove rods 72. The inner sides of the four L-shaped groove rods 72 are evenly spaced and connected to the outer sides of the n-type hollow columns 2. Five first springs 73 are evenly spaced.

[0039] First, the operator lies on the chair body 1, and then swings left and right through the curved plate 3. The left and right swinging of the chair body 1 drives the operator to swing left and right so that the operator can lie comfortably. At the same time, when the chair body 1 swings to the left through the curved plate 3, the operator can push the armrest 4 to swing to the left. The left swinging of the armrest 4 drives the unlocking mechanism 5 to move downward. The downward movement of the unlocking mechanism 5 drives the triggering mechanism 6 to move downward. The downward movement of the triggering mechanism 6 operates through the n-type rack 401. When the unlocking mechanism 5 moves downward and contacts with the driving mechanism 7, the unlocking mechanism 5 drives the driving mechanism 7 to unlock. The triggering mechanism 6 drives the driving mechanism 7 to move downward through the magnetic force. The driving mechanism 7 moves downward and contacts with the ground. The driving mechanism 7 generates a thrust through the ground to drive the curved plate 3 to swing. The swinging of the curved plate 3 drives the chair body 1 to swing through the n-type hollow column 2, which makes the operator swing again and triggers the triggering mechanism 6 to swing downward. When the trigger mechanism 6 continues to move downward to the maximum stroke, the trigger mechanism 6 drives the driving mechanism 7 to move upward and reset through magnetic force, the driving mechanism 7 resets and disengages from the ground, pulls the armrest 4 to swing right and reset, the unlocking mechanism 5 moves upward and resets and disengages from the driving mechanism 7, the driving mechanism 7 continues to be locked, the unlocking mechanism 5 resets and also drives the trigger mechanism 6 to move upward and reset, the trigger mechanism 6 resets and disengages from the driving mechanism 7, and the trigger mechanism 6 moves upward and resets and engages with the telescopic rod 402 and is limited. Similarly, when the chair body 1 swings to the right, the armrest 4 is pushed to swing to the right, and the driving mechanism 7 continues to contact the ground to generate thrust to drive the arc plate 3 to swing to the left, which also makes the chair body 1 swing to the left. This is repeated, and the chair body 1 can be continuously made to swing back and forth more persistently, so there is no need to swing the chair body 1 again by the person himself, which is more convenient. When it is not necessary to make the chair body 1 swing continuously and persistently, there is no need to push the armrest 4 to swing left and right, and the chair body 1 can stop after swinging for a period of time, and the operator can get off the chair body 1.

[0040] When the chair body 1 swings to the left, the armrest 4 is pushed to swing to the left and contact with the left movable frame 51. The armrest 4 swings to the left and drives the left movable frame 51 to move downward, the left elastic member 54 is compressed, and the left movable frame 51 moves downward, driving the left trigger rod 53 and the left cylinder 52 to move downward. The left cylinder 52 moves downward and drives the trigger mechanism 6 to move downward and disengage from the telescopic rod 402. The trigger mechanism 6 continues to move downward and operates through the n-shaped rack 401. When the left trigger rod 53 moves downward and contacts with the drive mechanism 7, the left trigger rod 53 drives the drive mechanism 7 to unlock. The trigger mechanism 6 drives the drive mechanism 7 to move downward and contact with the ground through magnetic force. The drive mechanism 7 generates thrust through the ground, which makes the chair body 1 swing to the right, pulling the armrest 4 to swing to the right and reset. Due to the action of the side elastic member 54, the left movable frame 51 moves upward and resets, driving the cylinder 52 and the trigger rod 53 to move upward and reset. The cylinder 52 moves upward and resets, driving the trigger mechanism 6 to move upward and reset. The trigger mechanism 6 resets and drives the driving mechanism 7 to move upward and reset. The trigger mechanism 6 resets and continues to engage with the telescopic rod 402 and is limited. At the same time, the left trigger rod 53 resets and disengages from the driving mechanism 7. The driving mechanism 7 is reset and locked. Similarly, when the chair body 1 swings to the right, it pushes the armrest 4 to swing to the right and contact the right movable frame 51. The right cylinder 52 also moves downward, which makes the driving mechanism 7 move downward and generate thrust with the ground, making the chair body 1 swing to the left, and then pull the armrest 4 to swing to the left and reset. The right cylinder 52 drives the right movable frame 51 to move upward and reset.

[0041] When the operator pushes the armrest 4 to swing to the left, the left cylinder 52 moves downward and drives the left transmission assembly 66 to move downward through the left fixed shaft 67. The left transmission assembly 66 moves downward and drives the left gear 68 to move downward. At the same time, the left fixed shaft 67 moves downward and also drives the left connecting plate 65 to move downward. The left connecting plate 65 moves downward and drives the left rotating frame 63 to move downward. The left rotating frame 63 moves downward and drives the left magnetic block 61 to move downward. At this time, the left magnetic block 61 is in a repulsive state with the driving mechanism 7. The left rotating frame 63 moves downward and also drives the left hexagonal block 64 to move downward. The left hexagonal block 64 moves downward and is aligned with the left The wide upper portion of the slot 62 is out of contact, and the left slot 62 limits the left hexagonal block 64. The left hexagonal block 64 limits the left rotating frame 63, and the left magnetic block 61 is also limited. At this time, the left gear 68 is meshed with the n-type rack 401, and the left gear 68 moves downward and rotates through the n-type rack 401. The rotation of the left gear 68 drives the left transmission assembly 66 to rotate, and the left torsion spring 69 is compressed. When the drive mechanism 7 is unlocked, the left magnetic block 61 drives the drive mechanism 7 to move downward and contact the ground through the repulsive force, which makes the chair body 1 swing to the right while being pushed up by the drive mechanism 7, which can increase The potential energy of the swing of the large chair body 1, at this time, when the left hexagonal block 64 continues to move downward to the position where the lower part of the left slot 62 is wide, the left hexagonal block 64 is not limited by the left slot 62, and the n-shaped rack 401 continues to mesh with the gear 68. Due to the action of the left torsion spring 69, the left magnetic block 61 rotates 180 degrees and is attracted to the drive mechanism 7 by magnetic force. The left magnetic block 61 drives the drive mechanism 7 to move upward and break contact with the ground, pulls the armrest 4 to swing right and reset to break contact with the left movable frame 51, and the left cylinder 52 moves upward to reset and drives the left fixed shaft 67 to move upward to reset, and the left magnetic block 61 moves upward to break contact with the drive mechanism 7 The left hexagonal block 64 moves upward and is limited by the left slot 62, and the left gear 68 continues to move upward and rotates through the n-type rack 401, and the left gear 68 also drives the left rotating assembly to rotate, and the left torsion spring 69 is stretched, and then when the left gear 68 is reset, the left gear 68 is engaged with the left telescopic rod 402 and is limited, and the left gear 68 is disengaged from the left n-type rack 401. At this time, the left hexagonal block 64 is not limited by the left slot 62. Due to the action of the left torsion spring 69, the left magnetic block 61 rotates 180 degrees to reset. Similarly, when the armrest 4 is pushed to swing to the right, the right magnetic block 61 moves downward.

[0042] Initially, the magnet driving rod 71 and the magnetic block 61 repel each other through magnetic force. When the armrest 4 swings and drives the movable frame 51 to move downward, the trigger rod 53 moves downward and contacts the L-shaped groove rod 72. The trigger rod 53 drives the L-shaped groove rod 72 to move outward. The first spring 73 is stretched, and the L-shaped groove rod 72 moves outward and loses contact with the magnet driving rod 71. Due to the magnetic repulsion, the magnetic block 61 drives the magnet driving rod 71 to move downward. The magnet driving rod 71 moves downward and contacts the ground to generate thrust, thereby increasing the potential energy of the swing of the chair body 1. Then, when the magnetic block 61 rotates 180 degrees, the magnetic block 61 attracts the magnet driving rod 71 through magnetic force, and the magnetic block 61 drives the magnet driving rod 71 to move upward and reset through magnetic force, and the magnet driving rod 71 resets and disengages from the ground. When the armrest 4 swings and resets without limiting the movable frame 51, the trigger rod 53 moves upward and resets and disengages from the L-shaped groove rod 72. Due to the action of the first spring 73, the L-shaped groove rod 72 moves inward and continues to contact the magnet driving rod 71, and the L-shaped groove rod 72 limits the magnet driving rod 71. In this way, every time the magnet driving rod 71 moves downward and contacts the ground, the potential energy of the swing of the chair body 1 can be increased, so that it can be shaken for a long time.

[0043] The invention also includes a limiting mechanism 8, which includes a limiting ring 81, a wedge plate 82, a movable rod 83, a second spring 84 and a third spring 85. Figure 1 , Figure 2 , Fig.13 and Fig.14 As shown, the left and right sides of the n-type hollow column 2 are symmetrically connected with limit rings 81 in a damping sliding manner. The convex end of the limit ring 81 contacts the L-shaped groove rod 72, and the limit ring 81 can limit the L-shaped groove rod 72. A third spring 85 is connected between the inner side of the limit ring 81 and the inner side of the n-type hollow column 2. A wedge plate 82 is installed between the two corresponding limit rings 81 on each side by welding. Active rods 83 are symmetrically slidably connected on the front and rear arc plates 3. The top ends of the four active rods 83 are respectively in contact with the inclined surfaces of the four wedge plates 82. When the active rods 83 move upward, the active rods 83 can drive the wedge plates 82 to move. The lower parts of the four active rods 83 are connected to the inner side surfaces of the arc plates 3 with second springs 84.

[0044] Initially, the limiting ring 81 limits the L-shaped groove rod 72. When the arc plate 3 swings, the arc plate 3 also drives the movable rod 83 to swing through the second spring 84. At the same time, the swing of the n-shaped hollow column 2 also drives the limiting ring 81 to swing. The swing of the limiting ring 81 drives the wedge plate 82 to swing. When the movable rod 83 swings and contacts the ground, the ground limits the movable rod 83. As the wedge plate 82 continues to swing, the movable rod 83 causes the swinging wedge plate 82 to move. The movement of the wedge plate 82 drives the limiting ring 81 to rotate. The third spring 85 is compressed, and the limiting ring 81 rotates without limiting the L-shaped groove rod 72. The trigger rod 53 continues to move downward to drive the L-shaped The groove rod 72 moves outward without limiting the magnet driving rod 71. When the arc plate 3 swings and drives the movable rod 83 to swing out of contact with the ground through the second spring 84, the movable rod 83 moves downward and resets due to the action of the second spring 84 without limiting the wedge plate 82. Due to the action of the third spring 85, the limit ring 81 rotates in the opposite direction to drive the wedge plate 82 to move in the opposite direction. Since the limit ring 81 and the n-shaped hollow column 2 are in a damping sliding connection, the limit ring 81 slowly rotates in the opposite direction. When the L-shaped groove rod 72 moves inward and resets, the limit ring 81 also rotates in the opposite direction to reset and continue to limit the L-shaped groove rod 72, thereby driving the wedge plate 82 to move and reset. In this way, when the arc plate 3 has not yet swung into place, the magnet driving rod 71 can be prevented from moving downward, thereby preventing the magnet driving rod 71 from contacting the ground too early and causing insufficient thrust.

[0045] Also includes a protective shell 9, see Figure 4 As shown, the outer side surfaces of the n-shaped hollow column 2 are fixedly connected with a protective shell 9 symmetrically on both sides, and the L-shaped groove rod 72 is located in the protective shell 9 , and the protective shell 9 can protect the L-shaped groove rod 72 .

[0046] Also includes a contact wheel 10, see Figure 7 As shown, the top ends of the four movable frames 51 are rotatably connected with contact wheels 10 , and the contact wheels 10 are in contact with the handrails 4 .

[0047] Also includes a rubber block 11, see Figure 5 As shown, the bottom ends of the four magnet driving rods 71 ​​are fixedly connected to rubber blocks 11 .

[0048] When the L-shaped groove rod 72 moves, the protective shell 9 protects the L-shaped groove rod 72, so that the L-shaped groove rod 72 can be prevented from being damaged by foreign debris and affecting subsequent use.

[0049] When the armrest 4 swings, the armrest 4 drives the movable frame 51 to move downward through the contact wheel 10, and the contact wheel 10 reduces the friction between the armrest 4 and the movable frame 51. In this way, the armrest 4 can drive the movable frame 51 to move more smoothly.

[0050] When the magnet driving rod 71 moves downward, the magnet driving rod 71 drives the rubber block 11 to move downward, and the rubber block 11 contacts the ground to increase friction, so that the magnet driving rod 71 contacts the ground through the rubber block 11 to generate thrust. When the magnet driving rod 71 moves upward to reset, the magnet driving rod 71 drives the rubber block 11 to move upward to reset. In this way, the magnet driving rod 71 can be more firmly in contact with the ground to generate thrust.
