Compared with the prior art, the present invention has the following beneficial effects:

In the present invention, the leg board is pushed down by the seat board, so that the first bracket moves forward along the first track, and the leg board is controlled to be converted from upright to horizontal. The back board is pulled down by the seat board, so that the second bracket moves obliquely along the second track, and the back board is controlled to be converted from a vertical to a horizontal inclined state. At this time, the user can lie down to complete the massage. Compared with the existing integrated massage chair, the leg board and the back board can form a vertical structure along the seat board. The user can easily sit on the seat board from a standing state, and then use the downward movement of the seat board to realize the deformation of the back board and the leg board, and lift the lower body and sink the upper body, so as to avoid safety hazards caused by users with inconvenient hands and feet bending or lying down in the massage chair, and have better safety in use.

In the present invention, the leg plate is rotated to make the internal front sliding pin rotate from vertical to horizontal and deviate from the front baffle, and the back plate is rotated downward to make the internal rear sliding pin also deviate from the rear baffle, so that the tension spring pulls the movable seat and the limit knife to completely slide into the slide groove. At this time, the massage plate can use the track block to make a certain offset along the track groove. Compared with the existing massage chair surface with a fixed structure, the cooperation of the above-mentioned track groove and the track block and other components enables the body to be offset along the back plate and the leg plate by using the massage plate without leaving the massage position after the user lies down, so as to adapt to the user's limb twisting, and the upper body and the lower body can lie sideways independently, avoiding the situation where the user suffers limb discomfort due to lying in a single posture for a long time.

In the present invention, during the process of the leg panels and the back panels returning to their original positions, the sliding pins on both sides are limited by the front baffle plate and the rear baffle plate respectively, and the movable block is pushed out of the sliding groove to lock the track block, and the limiting knife misaligned with the track block is inserted into the track groove. At this time, the massage panel and the track block cannot move, thereby ensuring the stability of the massage panel during the process of the back panels and the leg panels returning to their original positions, avoiding the uncontrolled displacement of the user's body, and reducing the risk of the user falling or spraining from the equipment.

In the present invention, the magnetic base is aligned with the magnetic pin, a repulsive force is applied to the magnetic pin to make it slide into the T-shaped hole, and the triangular head is used to squeeze the calipers on both sides to engage the calipers with the nut base. At this time, the nut base is connected to the slider, and the rotation of the screw rod can drive the seat plate to move up. When the magnetic base is not aligned with the magnetic pin, the nut base is not connected to the slider, but rotates idly with the screw rod. At this time, the seat plate, back plate and leg plate will not be reset, so the position of the back massage plate and the seat plate upward reset are controlled jointly, and the role of equipment insurance can be played, which can effectively prevent the back massage plate from rotating upward and resetting in an offset state, avoid injuries caused by the deformation of the back plate when the user's body is in a side-tilted state, and improve the safety of equipment use.

The use method and advantages of the present invention: When the head cover type massage chair that can relieve neck pain is in operation and use, the working process is as follows:

As shown in Figures 1, 2, 3, 4, 5 to 11:

S1. Sit on the seat board 3 from a standing position, with the back against the back board 4, and then use the screw rod 73 to drive the seat board 3 to move downward. During this process, the leg board 5 is pushed downward by the seat board 3, so that the first bracket 76 moves forward along the first track 74, and the leg board 5 is controlled to be transformed from vertical to horizontal. The back board 4 is pulled down by the seat board 3, so that the second bracket 77 moves obliquely along the second track 75, and the back board 4 is controlled to be transformed from a vertical state to a horizontal inclined state. At this time, the user can lie down and complete the massage;

S2, after the leg plate 5 rotates upward, the front sliding pin 7810 inside it rotates from vertical to horizontal and deviates from the front baffle 7811. After the back plate 4 rotates downward, the rear sliding pin 7810 inside it also deviates from the rear baffle 7812, so that the tension spring 785 pulls the moving seat 784 and the limiting knife 787 to completely slide into the sliding groove 783. At this time, the massage plate 6 can use the track block 781 to deviate along the track groove 782 to a certain extent;

S3, after the massage is completed, the seat plate 3 moves upward to return the leg plate 5 and the back plate 4 to their original positions. During this process, the sliding pins 7810 on both sides are limited by the front baffle plate 7811 and the rear baffle plate 7812 respectively, and the moving block is pushed out of the sliding groove 783 to press and lock the track block 781, and the limiting knife 787 misaligned with the track block 781 is inserted into the track groove 782, and the massage plate 6 and the track block 781 cannot move;

S4. When the massage board 6 reaches the middle position along the back board 4, the magnetic seat 78133 on its surface is aligned with the magnetic pin 78132, exerting a repulsive force on the magnetic pin 78132 to make it slide into the T-shaped hole 78131, and using the triangular head to squeeze the calipers 78136 on both sides to make the calipers 78136 engage with the nut seat 78135. At this time, the nut seat 78135 is connected to the slider 72, and the rotation of the screw rod 73 can drive the seat board 3 to move upward. When the magnetic seat 78133 is not aligned with the magnetic pin 78132, the nut seat 78135 is not connected to the slider 72, but rotates idly with the screw rod 73. At this time, the seat board 3, the back board 4, and the leg board 5 will not be reset.

The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments.
