Detailed Description

As shown in fig. 1-3, the cam type simple massage backrest chair of the present invention is composed of a seat 12 and a backrest, wherein the backrest comprises a box 1, a crankshaft 2 and a massage head 3. More than two crankshafts 2 are longitudinally arranged in a frame type box body 1, two ends of each crankshaft 2 are movably embedded in through holes of longitudinal frames at two sides of the box body 1, more than two cranks 4 are uniformly distributed on each crankshaft 2, through holes 6 corresponding to the positions of the cranks 4 are distributed on a bottom plate 5 of the box body 1, and a handle rod 7 of each massage head 3 passes through the through holes 6 and is hinged with the cranks 4. Cranks 4 in a longitudinal row at one end of each crankshaft are hinged one by a driving connecting rod 8, and one crankshaft 2 at the bottom passes through a through hole of the side wall of the frame of the box body 1 and is connected with a handle 9 of the crankshaft 2; the massage head 3 is formed by fixedly connecting a ball bowl 10 at the end of a handle 7, and freely rolling ball 11 is inserted into the notch of the ball bowl 10 in a clearance fit manner, thereby forming massage cams one by one. The crankshaft 2, the massage head 3, the driving connecting rod 8 and the integrated box body 1 are integrally embedded into a backrest of a seat 12, wherein the convex surface of each rolling ball 11 is arranged in each hollowed hole in front of the backrest of the seat 12, and each hollowed hole is formed by bandages 13 which are vertically staggered in a transverse direction and a vertical direction.

In the device, two end heads of a crankshaft 2 are cylinders, the middle part of the crankshaft 2 is a prism, a plurality of cranks 4 are uniformly arranged on the prism in the middle of the crankshaft 2, one end of each crank 4 is fixedly connected with the prism, the other end of each crank 4 is movably connected with one end of a handle rod 7, and the other end of the handle rod 7 penetrates through a through hole 6 to be vertically and fixedly connected with the rear end of a ball bowl 10 outside a box body 1; the upper and lower crankshafts 2 are connected through a driving connecting rod 8, the driving connecting rod 8 is movably connected to the upper and lower cranks 4, the driving connecting rod 8 hinges the cranks 4 on the same column of the crankshaft 2 one by one to form synchronous linkage of the crankshaft 2 one by one, and the massage heads 3 one by one are synchronously linked by pulling the handle 9. The box body 1 is embedded in the back of the seat 12 and is fixedly connected with the seat 12, the handle 9 is arranged at the outer bottom of the side wall of the seat 12, the front end of the back of the seat 12 is provided with vertical and horizontal vertically staggered bandages 13, and the massage heads 3 penetrate through hollow holes formed by the vertical and horizontal bandages 13 in a staggered manner.

After the two ends of the bandage 13 are tightened, a certain space is left between the bandage and the front end of the back with the radian of the seat 12, when the massage back rest chair is used, the handle 9 is turned downwards (as shown in figure 1), the two ends of the crankshaft 2 rotate because of being cylinders, the crank 4 rotates forwards synchronously with the rotation of the prism part of the crankshaft 2 by a certain angle, the upper and lower crankshafts 2 connected with the driving connecting rod 8 on the crank 4 rotate synchronously by an angle, and all the massage heads 3 can pass through the hollowed holes formed by the crisscross horizontal and vertical bandages 13 because the handle rod 7 is movably connected with the crank 4 and passes through the through hole 6 to be fixedly connected with the massage heads 3 outside the box body 1, and the handle rod 7 drives the massage heads 3 to move forwards along with the change of the rotation angle of the crank 4, so that a user can massage by slightly shaking the back of the back against the massage heads left and right at leisure; after the massage is finished, the handle 9 is pulled upwards, and contrary to the steps, the handle rod 7 can drive the massage head 3 to move backwards along with the change of the rotation angle of the crank 4 until the massage head 3 moves to the space left by the rear end of the bandage 13 and the front end of the back of the seat 12, at the moment, the massage back rest chair is a common chair, the bandage 13 on the back has good elasticity, and the comfort of the chair is improved.
