the seat plate comprises a seat plate 10, wherein side plates 7 are fixedly arranged on two sides of the seat plate 10, the seat plate 10 is arranged in a hollow manner, and an open part is arranged at the bottom of the seat plate 10;

the backrest 1 is hinged to the backrest 1 at the end part of the seat plate 10, a massage structure is installed on the backrest 1, a push-off plate 6 is installed on the inner side of the seat plate 10 in a sliding mode, the push-off plate 6 is connected with the backrest 1 through a transmission structure, and the push-off plate 6 is driven to move horizontally through the transmission structure when the backrest 1 is turned over.

Referring to fig. 3 and 5, the massage structure includes an installation groove formed on the backrest 1, two massage rollers 4 are installed inside the installation groove in a rotating manner, the two massage rollers 4 are connected through a third transmission belt 16, and one of the massage rollers 4 is connected to a driving structure installed on the back surface of the backrest 1.

The massage roller 4 comprises a roller body, and a plurality of massage bulges are spirally distributed on the roller body;

when the driving structure works, one of the massage rollers 4 is driven to rotate, and when one of the massage rollers 4 rotates, the other massage roller 4 is driven to rotate through the third transmission belt 16, so that the two massage rollers 4 synchronously rotate, and the back of a user is massaged through the massage bulges.

Referring to fig. 3, the driving structure includes a motor 2 fixedly mounted on the back of the backrest 1, and an output shaft of the motor 2 is connected to a rotating shaft of one of the massage rollers 4 through a first transmission belt 3.

It should be noted that, in the embodiment of the present invention, the motor 2 is a motor with a low rotation speed and a high torque, and of course, a motor with a high torque rotation speed may be used, and the present application does not specifically limit the type.

Referring to fig. 4 and 4, the transmission structure includes a transmission rod 15 penetrating through the two side plates 7 and rotatably connected with the two side plates 7, the transmission rod 15 is connected with the backrest 1 through a speed increasing structure, two first gears 13 are fixedly mounted on the transmission rod 15, the two first gears 13 are engaged with a rack 11 arranged at the bottom of the push-off plate 6, and the transmission rod 15 is connected with the elastic structure.

Referring to fig. 3 and 5, the speed increasing structure includes a speed increasing pulley 8 fixedly mounted on the rotating shaft of the backrest 1, and the speed increasing pulley 8 is connected to the transmission rod 15 through a second transmission belt 9.

When the backrest 1 is turned over, the speed-increasing belt wheel 8 is driven to rotate, and when the speed-increasing belt wheel 8 rotates, the transmission rod 15 is driven to rotate through the second transmission belt 9 and is increased in speed;

because the turned angle of the back 1 rotating shaft is smaller, the second transmission belt 9 is speeded up by the speed-increasing belt wheel 8, and the speed-increasing principle is that the big belt wheel drives the small belt wheel to increase speed.

Wherein, work as drive through acceleration rate structure during the upset of back 1 the transfer line 15 rotates, works as drive during the rotation of transfer line 15 first gear 13 follows the rotation, drives through rack 11 during first gear 13 rotates push away and take off board 6 and carry out the horizontal motion, so that back 1 drives when the upset and pushes away and takes off board 6 and carry out the horizontal motion to push up the shank when the user relies on and support, make it have higher travelling comfort when the massage, the transmission through rack 11 and first gear 13 has comparatively stable transmission.

Referring to fig. 4 and 6, the elastic structure includes a guide rod 17 fixedly mounted at the bottom of the seat plate 10, the guide rod 17 is rectangular and has a circular end, a rack plate 12 is slidably mounted on the guide rod 17, the rack plate 12 is engaged with a second gear 14 fixedly mounted on the transmission rod 15, and a spring 18 is sleeved on the circular portion of the guide rod 17.

When the transmission rod 15 rotates, the second gear 14 is also driven to rotate, when the second gear 14 rotates, the rack plate 12 is driven to move horizontally, when the rack plate 12 moves, the spring 18 is compressed, so that the spring 18 stores a certain elastic potential energy, when a user leaves the backrest 1, the rack plate 12 is driven to move horizontally in the opposite direction by releasing the elastic potential energy stored by the spring 18, so that the second gear 14 is driven to rotate horizontally in the opposite direction by the horizontal movement in the opposite direction of the rack plate 12, and the transmission rod 15 is driven to rotate in the opposite direction by the second gear 14, so that the whole body returns to the initial position.

When a user leans on the backrest 1, the backrest 1 is driven by the transmission structure to horizontally move the push-off plate 6 and drive the elastic structure to work when being overturned, when the backrest 1 is overturned to the tail end of the stroke, the waist of the patient is massaged by the massage structure to play a role in releasing and relieving pressure, and when the user leaves, the elastic structure drives the whole body to return to the initial position.

The embodiment of the utility model provides an in, order about back 1 to overturn when the user sits to seat 10 and leans on to back 1, turn over to certain angle simultaneously lead to fixed mounting in locating part 5 on the seat 10 advances spacingly to its stroke, makes it be in comfortable angle relatively, and simultaneously, the waist atress.

When the backrest 1 is turned over, the speed-increasing belt wheel 8 is driven to rotate, and when the speed-increasing belt wheel 8 rotates, the transmission rod 15 is driven to rotate through the second transmission belt 9 and is increased in speed, for example, the rotating shaft of the backrest 1 rotates ninety degrees, and the transmission rod 15 can rotate for multiple circles after the speed is increased.

When the transmission rod 15 rotates, the second gear 14 and the first gear 13 are driven to rotate along with the rotation, and when the first gear 13 rotates, the rack 11 drives the push-off plate 6 to move horizontally so as to drive the first transmission belt 3 to extend out to support the legs of a user when the backrest 1 is turned over, so that the user can change the posture and is more comfortable;

the rack plate 12 is moved horizontally when the second gear 14 rotates, so that the spring 18 is compressed by the rack plate 12 and stores a certain elastic potential energy.

When the motor 2 rotates, the output shaft of the output end drives the massage roller 4 through the first transmission belt 3, the waist of a user is massaged through the massage protrusions when the massage roller 4 rotates, blood circulation is promoted through massage, and a relaxing effect is achieved.

When the patient gets up, the rack plate 12 is driven to move horizontally in the opposite direction by the elastic potential energy of the release spring 18, so that the second gear 14 is driven to rotate in the opposite direction by the rack plate 12, and the backrest 1 is driven to turn in the opposite direction to the initial position by the transmission rod 15.

The utility model discloses still another embodiment can be with the spacing axle of movable mounting on the curb plate 7, carries on spacingly through the loose axle to back 1 when not using, makes it can not overturn.

To sum up, the utility model drives the backrest 1 to turn by the patient's dependence, drives the push-off plate 6 to move horizontally by the turning of the backrest 1, supports the legs of the patient by the push-off plate 6, ensures that the patient has a comfortable lying and leaning posture, ensures that the stress position is positioned at the waist, and then massages the waist by the rotation of the massage roller 4;

secondly, the utility model discloses back 1 is the upset state when using, pushes away takes off board 6 for stretching out the state, gets back to initial position when not using, makes its occupation space lower when not using, and daily can use as flat bench, does not order about whole work at not relying on back 1.
