Description
Technical Field
The invention relates to the technical field of sit-up exercise equipment, in particular to sit-up exercise equipment for a community.
Background
Sit-up, a way to exercise the body. Supine, closing the legs, lifting the hands, contracting the abdominal muscles, swinging the arms forward to quickly get a sitting posture, continuing the forward bending of the upper body, touching the foot surface with the hands, and lowering the head; and then returned to the sitting position. This is done continuously. The speed of doing sit-ups varies from person to person. Initially 5 attempts may be made at one minute, after which the increase is slowly increased until about 50 attempts are made. Women under 30 years old are mostly practised for the purpose of preventing gynecological diseases, and the frequency is preferably controlled to be 60-70 per minute, and decreases with the increase of age, and 25 women over 50 years old are needed. For those with certain fitness foundation, the aim of strengthening the abdominal strength is to be achieved through practice, and about 60 times of practice is guaranteed in one minute.
Most of the existing sit-up exercise equipment for the residential area can only carry out single sit-up, and various exercises are carried out, so that exercise equipment of various different types needs to be configured, and the exercise input cost is increased.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention provides a multifunctional sit-up exercise device which can exercise the strength of the upper limbs, the lower limbs and the abdomen of a user, and the invention aims to solve the technical problems that: how to make the sit-up exercise equipment have a plurality of fitness functions.
In order to solve the above technical problems, the present invention provides a sit-up exercise device for a community, comprising: comprises a first pipe; one ends of the two mounting plates are fixedly connected to the two ends of the first pipe respectively; the two ends of the second pipe are fixedly connected with the other ends of the two mounting plates, and the first pipe is parallel to the second pipe; the two support assemblies are fixedly connected to the first tube and the second tube; the two exercise components are respectively and fixedly arranged on the two mounting plates and comprise handrails, a base and a rotating shaft, the base is fixedly connected to the upper surfaces of the mounting plates, and two ends of each handrail are rotatably connected to the base through the rotating shaft; the torsion spring is arranged on the rotating shaft and used for keeping the handrails in a vertical state, when the head of a user leans against the supporting component towards the right back, the two handrails are respectively held by the two hands of the user, then the handrails are rotated outwards or inwards by the force of arms, and the torsion spring is opposite to the arms at the moment, so that the muscle training of the arms of the user is realized; the connecting assembly is arranged on the right side of the supporting assembly and comprises a cross rod, a connecting rod and a wrist tube, two ends of the cross rod are rotatably connected with the fixing rods, a torsion spring used for keeping the connecting rod in a vertical state is arranged between the cross rod and the fixing rods, and the wrist tube is fixed above the cross rod through the connecting rod; lower limbs training subassembly, lower limbs training subassembly fixed connection No. two pipes, lower limbs training subassembly includes torsion bar, leg, hollow tube, connector, locating pin and inserted block, the hollow tube slope is fixed No. two are managed, connector sliding connection in the hollow tube top, the connector deviates from the one end fixed connection of hollow tube the leg, the one end of torsion bar is passed through inserted block fixed mounting in on the leg, the torsion bar other end rotates to be connected in on the wrist, the connector passes through the locating pin with hollow tube fixed connection, the locating pin passes through the rope and connects on the hollow tube, avoid the locating pin to lose, the inserted block passes through the rope and connects on the leg, avoid the inserted block to lose.
