Detailed ways

As shown in Figure 1-13, a back massager includes a column 1, a waist massager 2, a stool 3 and a back massager 4, the column 1 stands vertically on the ground, and the waist massager 2 is hinged on the side of the column 1 The other side of the column 1 has a chute 11, and the stool 3 stands on the ground and is located between the arms of the waist massager 2.

The back massager 4 comprises a main frame 41, a pair of rocking arms 42, a pair of connecting rods 43 and a pair of massage modules 44; the main frame 41 is slidably connected in the chute 11, one end of the rocking arm 42 is hinged in the main frame 41, One end is suspended outside; one end of the connecting rod 43 is hinged on the rocker arm 42, and the other end is rotatably connected with the massage module 44;

A rack 111 is fixedly connected to the column 1 , a drive shaft 411 is rotatably connected to the main frame 41 , a gear 412 is fixedly connected to the drive shaft 411 , and the gear 412 meshes with the rack 111 .

The outside of the main frame 41 corresponding to the position of the gear 412 is fixedly connected with a limiting block 413, and the limiting block 413 is stuck on the inner wall of the column 1 to limit and prevent the back massager 4 from falling off the column 1.

The contact surface of the limiting block 413 and the inner wall of the column 1 is an arc surface; the contact of the arc surface can reduce the frictional force and avoid time-consuming and labor-intensive movement of the main frame 41 .

A pair of crawler belts 414 are also sleeved on the driving shaft 411, and the main frame 41 is rotatably connected with a driven shaft 415 on the inner wall close to the massage track 45; the two ends of the crawler belts 414 are respectively sleeved on the driving shaft 411 and the driven shaft 415; 42 and the hinge of the main frame 41 are sleeved with a torsion spring 421 , one end of the torsion spring 421 is fixedly connected to the rocker arm 42 , and the other end is slidably connected to the crawler belt 414 .

The surface of crawler belt 414 is fixedly connected with sliding ring 416, and the end of torsion spring 421 is slidingly connected with crawler belt 414 through sliding ring 416; sliding connection on the lower surface.

A large spring 417 is connected between the top surface of the inner wall of the chute 11 and the main frame 41; when the main frame 41 is moved, the large spring 417 plays a certain labor-saving effect.

The cross-section of the massage track 45 is curved toward the outside, and this curved shape adapts to the shape of the back of the human body.

A small spring 431 is connected to the bottom inner wall of the main frame 41, and the other end of the small spring 431 is connected to a locking block 432. The inner side of the locking block 432 is socketed in the bottom inner wall of the main frame 41, and the outer side extends out of the main frame 41;

A fixed caliper 112 is fixedly connected to the position corresponding to the locking block 432 in the column 1, and a fixed card groove 113 corresponding to the size of the outer part of the locking block 432 is uniformly opened on the fixed caliper 112; the locking block 432 is fixed to the fixed card groove 113 The relative position of the main frame 41 and the column 1.

The lower surface on the outside of the locking block 432 is horizontal, and the upper surface has an inclined slope. The shape of the fixed slot 113 corresponds to the shape of the outer side of the locking block 432; A hole is provided at the position corresponding to the inclined-plane block 433 , and a movable block 434 is slidably connected to the hole, and the top of the movable block 434 is in contact with the slope of the inclined-plane block 433 .

When in use, the user stands between a pair of rocker arms 42, with his back against the massage module 44, holds the rocker arm 42 with both hands, and rotates the rocker arm 42 with force from both arms. Rod 43 moves, and connecting rod 43 promotes massage module 44 again, makes massage module 44 move along the track of massage track 45 in massage track 45, and the user can be exercising arm like this, and massage module 44 rolls on the user's back, Massage the back in different positions.

When the user's height and body shape are inconsistent, it is inevitable that the best exercise effect cannot be exerted. At this time, the user adjusts the height of the main frame 41 to adapt to his body shape.

When it is necessary to move the main frame 41 upwards, hold the rocker arm 42 or the main frame 41 with both hands and push it upwards. At this time, the inclined surface of the locking block 432 contacts the inclined surface of the fixed locking groove 113, and the locking block 432 is pushed inward during the moving process. , the small spring 431 is squeezed, and when the locking block 432 encounters the next fixed slot 113, it pops up under the elastic force of the small spring 431 and is stuck and fixed in the position of the next fixed slot 113.

When the main frame 41 needs to be moved downward, at first hold the bottom of the main frame 41 with one hand, and squeeze the movable block 434 at the bottom of the main frame 41, the movable block 434 is pushed upwards, and the inclined-plane block 433 is pushed inwardly, and the inclined-plane block 433 drives the locking block 432 to move inwardly, and squeezes the small spring 431, and the locking block 432 is disengaged from the fixed slot 113. At this time, the large spring 417 balances the gravity of a part of the main frame 41, which plays a labor-saving role; the user will After the main frame 41 moves to a suitable height, the movable block 434 is released, and under the elastic force of the small spring 431 , the locking block 432 is snapped into the corresponding fixed slot 113 nearby.

When the user adjusts the height of the main frame 41 , the top of the main frame 41 is limited by the limit block 413 and the inner wall of the chute 11 to keep the movement and adjustment process stable and firm.

At the same time, when the height of the main frame 41 is adjusted, the gear 412 and the rack 111 rotate relative to each other, and the rotation of the gear 412 serves as the active power to drive the drive shaft 411 to rotate together, and the crawler belt 414 sleeved on the drive shaft 411 has a certain displacement accordingly. , the end of the torsion spring 421 moves together with the sliding ring 416 fixed on the crawler belt 414, because the position of the end of the torsion spring 421 moves is different, the torsion force of the torsion spring 421 can be changed, and therefore the torsion of the rocking arm 42 can be adjusted.

When the main frame 41 moved upwards, the torsion of the torsion spring 421 was increased, which was suitable for people with high body shape and weight to exercise.

The above; is only a preferred embodiment of the present invention; but the protection scope of the present invention is not limited thereto; any person familiar with the technical field is within the technical scope disclosed in the present invention; according to the technical solution of the present invention Equivalent replacements or changes thereof and their improved concepts should be covered within the protection scope of the present invention.
