Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, including base 1, base 1 rear side rotation is connected with vertical direction and follows the pivot 2 that left right direction distributes, be equipped with backup pad 3 on the pivot 2, two backup pad 3 can be relative or swing back to back of the body mutually, 3 upper surfaces of backup pad are the arcwall face and are equipped with a plurality of massage gasbag 4, be equipped with the cavity 5 with massage gasbag 4 intercommunication in the backup pad 3, rotation is connected with cam 6 on the pivot 2, the inside interior ratchet that is equipped with of cam 6, it has can with interior ratchet complex pawl 7 to articulate in the pivot 2, cam 6 one side is equipped with aerating device, aerating device communicates through trachea 8 and cavity 5.

In order to enable the two support plates 3 to swing oppositely or oppositely, a rack 9 is connected in the base 1 in a sliding mode, the rear end of the rack 9 extends out of the base 1, and a gear 10 which can be meshed with the rack 9 and is located above the cam 6 is fixed on the rotating shaft 2.

In order to prevent the cam 6 from rotating along with the back-to-back swinging of the two supporting plates 3, one side of the pawl 7 close to the base 1 is connected with the rotating shaft 2 through a spring 11.

The inflating device comprises a cylinder 12, the cylinder 12 is fixed on the rear side of the base 1, a piston 13 is connected in the cylinder 12 in a sliding mode, one end of the piston rod extends out of the cylinder 12 and can be in contact with the outer edge surface of the cam 6, one side, far away from the piston rod, of the piston 13 is connected with the bottom of the cylinder 12 through a pressure spring 14, and one end, far away from the cam 6, of the cylinder 12 is communicated with the air pipe 8.

In order to facilitate the pushing of the rack 9 to move, a vertical push rod 15 is arranged at the rear end of the rack 9.

In order to achieve better inflation and exhaust effects of the massage air bag 4 and enhance the massage effect on the legs of the human body, the cam 6 is provided with four convex ends.

When the utility model is used, the two supporting plates 3 are arranged in a combined state, and the massage air bag 4 is in an initial flat state; a trainer sits on the base 1, two legs are respectively placed on the supporting plates 3, the push rod 15 is pushed backwards, the push rod 15 drives the rack 9 to move backwards, the rack 9 and the two gears 10 are simultaneously meshed to enable the two supporting plates 3 to swing back to back, so that ligaments on the two legs are gradually stretched, meanwhile, as the right rotating shaft 2 rotates clockwise and the left rotating shaft 2 rotates anticlockwise, when the rotating shaft 2 drives the pawl 7 to rotate, the pawl 7 extrudes the spring 11 and cannot drive the corresponding cam 6 to rotate, at the moment, the inflating device does not act, and the massage airbag 4 does not act;

when the angle between the two supporting plates 3 reaches a ligament training standard angle formulated by a trainer, the push rod 15 is pulled forwards, the push rod 15 is meshed with the gear 10 through the rack 9 to enable the two supporting plates 3 to swing oppositely, meanwhile, the rotating shaft 2 drives the pawl 7 to drive the corresponding cam 6 to rotate, when the protruding end of the cam 6 gradually pushes the piston 13 to slide in the cylinder 12 through the piston rod, the pressure spring 14 is compressed, and gas in the cylinder 12, which is far away from one side of the cam 6, enters the cavity 5 through the air pipe 8 and then enters the massage air bag 4 to extrude the legs of a human body;

along with the rotation of the cam 6, when the protruding end of the cam 6 begins to be separated from the end part of the piston rod, the pressure spring 14 pushes the piston 13 to move towards one side of the cam 6, gas in the massage airbag 4 enters the cylinder 12 through the cavity 5 and the air pipe 8, and in the relative swinging process of the two supporting plates 3, the continuous operation of the cam 6 enables the inflating device to continuously inflate and exhaust the massage airbag 4, so that the massage on the legs of a human body is realized, the strain of ligaments and muscles is relieved, and the training effect is enhanced.
