Background

The forward bending of the sitting position is a physical health test project of the colleges, the middle and the schools, and the test aim is to measure the possible activity range of joints such as the trunk, the waist, the hip and the like in a static state and mainly reflect the extensibility and elasticity of the joints, ligaments and muscles of the parts and the development level of the body flexibility. At present, the measuring device for forward bending of a sitting body is quite common, but training devices are rare, and students are difficult to gradually enhance the flexibility of joints such as trunks, waists, hips and the like. In the chinese utility model patent of publication No. CN208405931U, a body anteflexion and upper limbs strength comprehensive training ware is disclosed, the practitioner is just to a side of base, both legs are drawn together and are straightened, the pedal is on the side of base, hold the handle, rotate the handle, tensile shortening, the upper part of the body is anteflexion, until can not extend, so that the extensibility of oneself joint reaches the highest, but this requires the student to rotate the handle by oneself so that shorten stay cord length, it is inconvenient that both hands rotate the handle again when holding the handle, and owing to lack of intervention of external force, the student hardly further extends the pliability of oneself joint.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming above-mentioned technical shortcoming and providing a student's seat body anteflexion exerciser, through rotating the turning handle to make the pull ring be close to the telescopic link gradually, the joints such as the student's of trainning truck, waist, hip are slowly pulled open, through uninterruptedly periodic training, utilize external force auxiliary can realize the purpose of the flexibility of joints such as crescent student truck, waist, hip.

The utility model provides a technical scheme that technical problem adopted does: a student sitting body forward bending exerciser comprises a base, a supporting plate fixing plate and a rotating rod, wherein the supporting plate is fixedly connected to the middle of the upper end face of the base, two telescopic rods are fixedly connected to the middle of the top end of the supporting plate, the front telescopic rod is provided with corresponding fastening knobs towards the front side and the rear telescopic rod towards the rear side, the heights of the telescopic rods are adjusted, the fastening knobs are used for screwing and fixing, the height of the device can be adjusted according to the heights of different students, the fixing plate is fixedly connected to the upper portion of the left side of the front telescopic rod, the rotating rod is inserted into the top of the left side of the front telescopic rod, the rotating rod is fixedly connected with limiting rings on the left side and the right side of the supporting rod, the right end of the rotating rod is fixedly connected with a rotating handle, the left end of the rotating rod is fixedly connected with a threaded rod, the left end of the, the left end of the movable rod is fixedly connected with a pull ring, a structure related to the right side of the upper portion of the rear telescopic rod and a structure related to the left side of the upper portion of the front telescopic rod are the same in direction and opposite in direction, a student sits on the base, two legs are folded and straightened, the side face of the supporting plate is pedaled, the pull ring is held by a hand, other students or teachers rotate the rotating handle to drive the threaded rod to rotate through the rotating rod, the movable rod cannot rotate and only can move left and right due to the fact that the sliding block is clamped in the sliding groove at the moment, the movable rod drives the pull ring to be gradually close to the telescopic rod along with the movable rod, joints of a student to be trained, such as a trunk, a waist and a hip, are slowly pulled open until the student to feel that the current limit is reached by the student, periodic training is uninterruptedly performed, the purpose.

Further, the contact of base left and right sides up end is connected with the cushion to in the comfort level when improving the student and sitting on the base, the cushion can be removed, in order to wash the change.

Furthermore, the upper end surface of the fixing plate is provided with scale marks at the front side of the sliding groove so as to quantitatively control the forward bending exercise of the student seat body.

The utility model discloses the beneficial effect who has is: the height of the telescopic rod is adjusted, and the telescopic rod is screwed and fixed by utilizing the fastening knob, so that the height of the device can be adjusted according to the heights of different students; the student sits on the base, the two legs are folded and extended, the side faces of the supporting plates are pedaled, the pull ring is held by hands, other students or teachers rotate the rotating handle, so that the pull ring is gradually close to the telescopic rod, joints of the trunk, waist, hip and the like of the student to be trained are slowly pulled open until the student to be trained feels that the current limit is reached, the aim of gradually increasing the flexibility of the joints of the trunk, waist, hip and the like of the student can be achieved by means of external force assistance through uninterruptedly periodic training, and two sets of same structures on the left side and the right side can be used by two persons at the same time.
