DETAILED DESCRIPTION

[0021] The practical technical solution is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] Embodiment: A fitness chair, such as Figure 1-5 As shown, the chair body includes a chair back, a chair board and a base. The chair back and the chair board are both hinged to the base and can rotate. At the same time, a chair back angle adjustment device is provided between the chair back and the chair board. The device adopts the existing general structure and is not the innovation of this patent, so it will not be described in detail. Universal wheels are provided at the four corners of the base. The bottom of the chair board is hinged with a support frame. The top of the base is provided with a groove. When the support frame is inserted into the groove, the chair board is raised to facilitate the foot lifting exercise. When the support frame is not embedded in the groove, the chair board is at a normal height, which is suitable for no foot lifting exercise, such as daily sitting or just arm stretching. A headrest is hinged at the top of the chair back, which is used as a headrest during work and leisure. When exercising, the headrest is moved back to prevent interference.

[0023] An arm stretching structure is provided on both sides of the chair body. The arm stretching structure includes a pull ring, a counterweight, a gantry and a rope. The rope is made of steel wire rope. A sliding rod is provided between the gantry and the bottom of the chair body. The counterweight is slidably arranged on the sliding rod. The chain lifts the counterweight through a pulley block and a rope. A V-shaped pulley block and two ropes are formed by two fixed pulleys and one movable pulley. When the arm stretching structure or the foot lifting structure is used, the counterweight is only pulled from one end of the first rope, shortening the moving height of the counterweight under the same stretching distance, which is conducive to reducing the volume of the fitness chair and leaving enough space for the backrest to recline. The movable pulley on the top of the counterweight block and the two fixed pulleys on the top of the gantry are provided with guide wheels for guiding. There are two ropes, the first rope and the second rope. The first rope passes through the fixed pulley on the counterweight block, one end of which is connected to the foot lifting structure and the other end is connected to the arm stretching structure. The second rope passes through the movable pulley and the two ends are respectively connected to the pull rings on the left and right sides. The movable pulley is connected to one end of the first rope. In order to increase the movement distance of the rope, a hollow column is provided at the rear of the chair body. The top of the hollow column and the part close to the gantry are provided with guide wheels. The first rope passes through the guide wheel on the top of the hollow column and is connected to the second rope. A pair of guide wheels are provided at both ends of the chair body. After the end of the second rope passes through it, it passes through the bottom of the pull ring. The end of the second rope has a fixed head fixed to it. The fixed head is hollow and can be passed through by the second rope. The fixing method can be glue, screws, welding or other methods. A plane bearing is provided between the fixed head and the bottom of the pull ring. The bottom of the pull ring is set to be flat to prevent the pull ring from being embedded in the two guide wheels. A gripper is provided on the pull ring.

[0024] The foot-lifting structure includes a pressure rod and a connecting arm. A fixed shaft is provided on one side of the chair body. One end of the connecting arm is rotatably connected to the fixed shaft, and the other end is fixedly connected to the pressure rod. A fixed limit piece is provided on the inner end of the pressure rod. After the corresponding second counterweight block is strung on as needed, a sleeve is put on to press the second counterweight block, and then a fixed limit piece is installed on the outside to fix it. The fixed limit piece is a circular ring. After being put into the pressure rod, it is fixed with screws. A layer of sponge is wrapped on the outside of the sleeve. In order to prevent the second counterweight block from shaking during movement, the inner hole of the second counterweight block and the pressure rod are clearance-matched.

[0025] The bottom of the chair body is provided with a locking structure. When the foot-lifting structure is not needed, it is fixed under the chair board of the chair body to prevent it from being obstructed. The locking structure includes a support and a movable baffle. The movable baffle is rotatably fixed in the support, and the top protrudes from the support. A limiter is also provided inside the support, so that the movable baffle cannot move outward and can only rotate inward. The bottom end of the movable baffle exceeds the bottom of the support, that is, the bottom of the support can be used as a limiter. At the same time, the weight of the lower part of the connection point between the movable baffle and the support is greater than the weight of the upper part, so that it can automatically reset when there is no external force. When the pressure rod is pushed inward, the movable baffle is pressed down. When the pressure rod passes over the movable baffle, the movable baffle is reset to limit the pressure rod from moving outward, and the pressure rod is restricted on the support. A fixed constraint is provided at the bottom of the chair body, and one end of the first rope passes through the fixed constraint and is fixed to the pressure rod.

[0026] The overall fitness chair is more integrated and compact than the existing ones. It can be used as a seat normally and is easy to move. When you need to stretch your arms and exercise your arm muscles, you can sit on the chair, hold the pull rings on both sides or one side with your hands, and do stretching exercises to exercise your arm and chest muscles. You can also stand up and sit facing the chair to stretch and exercise, which can also exercise your shoulder muscles at the same time; when you need to exercise your legs, lift the chair board, let the support frame fall naturally into the groove, and the pressure bar will fall out. Sit on the chair, hook your feet on the pressure bar, and do foot-lifting exercises. You can also increase the counterweight on the pressure bar as needed, or adjust the chair back, lie back and do sit-ups to exercise your abdomen. After finishing, lift the chair board to lower the support frame to restore it to normal height, kick the pressure bar inward, and fix it with the locking structure.

[0027] The above content is a further detailed description of the technical solution provided in combination with the preferred implementation methods of this patent. It cannot be determined that the specific implementation of this utility model is limited to the above descriptions. For ordinary technicians in the technical field to which this patent belongs, without departing from the concept of this patent, they can also make several simple deductions or substitutions, which should be deemed to fall within the scope of protection of this patent.
