When the driving sprocket 32 rotates, the rotating sprocket 34 and the swinging sprocket 33 are driven to start to rotate synchronously, the rotating sprocket 34 drives the massage roller 22 to start to rotate to massage the legs, and the swinging sprocket 33 drives the supporting piece 21 to swing up and down in the rotating process through the eccentrically arranged rocker 35, so that the bending, stretching and loosening of the legs are realized, and the massage is more comfortable and efficient.

Further, the massage roller 22 includes a connection shaft 221 and a massage sleeve 222 sleeved on the outer side of the connection shaft 221, and two ends of the connection shaft 221 are fixedly connected with the chain 231. When the massage sleeve 222 is rotationally connected with the connecting shaft 221, the massage sleeve 222 moves along with the rotation direction of the chain 231, and forms extrusion with the upper leg, and when moving, the massage sleeve 222 forms autorotation under the combined action of the leg pressure and the chain power, so that the contact surface with the leg muscles is increased, and the massage effect on the leg muscles is improved. When the massage sleeve 222 is fixedly connected with the connecting shaft 221, the massage sleeve 222 moves only along with the chain 231.

In this embodiment, physiotherapy couch body 1 afterbody is provided with a plurality of first fixing base 11, first fixing base 11 top with support piece 21 front end rotates to be connected, makes support piece 1 front end highly raise, with physiotherapy couch body 1 forms the difference in height, and the user's shank is bent knee and is placed convenience in addition massage mechanism 2 is also more comfortable when carrying out the luffing motion. A rotating shaft 4 is arranged between the first fixing seats 11, and the supporting piece 21 is connected with the first fixing seats 11 through the rotating shaft 4, so that the supporting piece 21 can rotate around the shaft connection position. The first fixing seat 11 is fixed with the bearing is installed at the joint of the rotating shaft 4, and when the rotating shaft 4 is supported, friction force possibly generated during rotation is reduced, and sensitivity is improved. The rotating chain wheel 34 is fixedly arranged at the center of the rotating shaft 4, the synchronous chain wheel 23 connected with the massage roller 22 is arranged in the U-shaped groove 211, two ends of the rotating shaft 4 penetrate through the supporting piece 21 and are connected with the synchronous chain wheel 23, and the rotating chain wheel 34 drives the massage roller 22 connected with the synchronous chain wheel 23 to start rotating when working. The rotating shaft 4 connects the rotating sprocket 34 with the synchronizing sprocket 23 while rotating the supporting member 21 with the first fixing seat 11, so as to drive the massage roller 22 to work, thereby omitting an additional connection structure, simplifying the connection structure, and enabling the rotating shaft 4 to simultaneously perform the functions of connection, fixation and transmission.

Further, the synchronizing sprocket 23 includes a chain 231, a driving sprocket 232 and a driven sprocket 233, the driving sprocket 232 is disposed at the front end of the U-shaped slot 211 and connected to the rotating shaft 4, the driven sprocket 233 is disposed at the rear end of the U-shaped slot 211, and the driven sprockets 233 on two opposite sides are connected by a shaft, and the driving sprocket 232 and the driven sprocket 233 are connected by the chain 231 for transmission. The massage rollers 22 are fixed on the chain 231 at equal intervals, an upper layer and a lower layer are arranged in the supporting member 21, and the driving sprocket 232 drives the chain 231 to rotate when rotating, so that the massage rollers 22 start to move along the rotation direction of the chain 231 to massage and relax the legs. In this embodiment, under the basis that the massage columns on the massage roller 22 can massage the leg, the arrangement method of the massage roller 22 cannot be in complete contact with the leg, and the massage roller 22 moves on a plane by rotating along with the chain 231, so that the basic area of the massage roller 22 and the leg is increased, the massage can be more thoroughly performed on the leg muscle, the massage is more uniform, and the use feeling is improved.

In this embodiment, the second fixing seat 12 for fixing the swing sprocket 33 is disposed at the tail of the physiotherapy couch body 1, the turntables 36 are disposed at two sides of the second fixing seat 12, the turntables 36 are rotatably connected with the second fixing seat 12 through bearings, and the bearings are used for improving the stability of the connection part, reducing friction force generated during rotation, and improving rotation sensitivity. The rocker 35 is eccentrically arranged on the turntable 36 and is rotationally connected with the middle part of the side wall of the support piece 21, and when the swing chain wheel 33 rotates, the eccentrically arranged rocker 35 is driven to start rotating. Because one end of the supporting member 21 is fixed to the first fixing seat 11, the swinging rod 35 only drives the supporting member 21 to swing up and down around the connection between the supporting member 21 and the first fixing seat 11. When the rocker 35 is located at the highest point of the turntable 36, the rear end of the massage mechanism 2 is higher than the front end, and when the rocker 35 is located at the lowest point of the turntable 36, the rear end of the massage mechanism 2 is lower than the front end, and the massage mechanism can continuously swing up and down to further achieve the flexion and extension relaxation of leg muscles, so that the massage effect is improved.
