Description

A kind of abdominal muscle training device loading weight bearing

Technical field

The invention belongs to body-building apparatus technical fields, and in particular to one kind can load the abdominal muscle training device of weight bearing.

Background technique

Abdominal muscle is the pith in human connective tissue composition, including rectus aabdominis, musculus obliquus externus abdominis, oblique and abdomen cross Flesh.When contraction of abdominal muscle, comptocormia and rotation can be made, and can prevent pelvis from leaning forward.Work of the abdominal muscles for lumbar vertebrae Dynamic and stability also has considerable effect, can also control the activity of pelvis and backbone.Kraftlos abdominal muscle may be led It causes pelvis to lean forward to increase with lumbar vertebrae physiological bending, and increases the probability of lumbago.Sit-ups are as a kind of side taken exercises Formula, can effective exercising abdominal muscles, it is very popular.The training method of sit-ups are as follows: lie on the back, legs joined, two on hand It lifts, using contraction of abdominal muscle, two-arm is swung forward, and rapidly at sitting posture, upper body continuation is anteflexion, and two hand haptic element faces are bowed, then restored At sitting posture, so it is carried out continuously.

The development of Chinese fitness equipment industry starts from late 1980s, with China's entry into the WTO and Beijing Olympics Bidding Success provides advantage and opportunity to develop for the development of fitness equipment industry, and body-building troop constantly expands as fitness equipment Material manufacturer brings dense business opportunity.There are various sit-up trainers, on the market to realize the mesh of exercising abdominal muscles 's.However, existing sit-up trainer is designed as fixed structure mostly, loaded weight by the way of holding dumbbell plate, It is not only inconvenient, but also the load limited amount of dumbbell plate, in addition to this, there is also some potential safety problemss.

Summary of the invention

Object of the present invention is to: it is intended to provide a kind of abdominal muscle training device that can load weight bearing, the not only operation of loaded weight Simply, safety, and the need of exercise of most of trainers can be can satisfy with the multiple dumbbell plates of on-demand loading.

To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:

A kind of abdominal muscle training device loading weight bearing, including front support rod, back support rod, connecting rod, column, backrest plate Hinge bar, sitting height hinge bar and leg support bar, the front support rod is parallel with back support rod and level is oppositely arranged, described Uprights vertical be fixed in the middle part of back support rod, it is solid that one end of the connecting rod is fixed in the middle part of front support rod, the other end It is connected to the top of column, the connecting rod is in being connected with limit assembly, the top of the column on the end face of front support rod Hinged with one end of backrest plate hinge bar, backrest plate hinge bar free end top is fixed with seat plate, the rear end of the seat plate It is hinged with backrest plate, the active segment of the backrest plate is held on the upper surface of backrest plate hinge bar, and the backrest plate hinge bar is certainly Hinged by end lower part and one end of sitting height hinge bar, the free end of the sitting height hinge bar limit by limit assembly solid It is fixed, it is fixed in the middle part of the free end of the backrest plate hinge bar with one end of leg support bar, the other end of the leg support bar The end left and right sides of upward bending, the leg support bar is connected with leg pressing sleeve, and the leg support bar is in bending Position is fixed with strut, is connected with supporting leg sleeve at left and right sides of the top of the strut, the upper front of the strut is connected with Loop bar can be arranged dumbbell plate on the loop bar, and the upper surface left and right edges position of the backrest plate is detachably equipped with two The identical shoulder belt of a structure, position of the upper surface of the backrest plate between two shoulder belts offers at least along the extending direction of plate One loading hole, the depth size of the loading hole are greater than the thickness of dumbbell plate, and the aperture size of the loading hole is greater than The diameter dimension of dumbbell plate, the loading hole are detachably equipped with cover board.

Using technical solution of the present invention, when needing to carry out load stomach workout, dumbbell plate is placed in loading hole, lid Upper cover plate and fixation, then trainer's buttocks is placed on seat plate, and back is placed on backrest plate, and both legs are placed in leg pressing sleeve and supporting leg Between sleeve, both hands pass through shoulder belt, so that shoulder belt is close to the both shoulders of trainer, lift on trainer's both hands, utilize contraction of abdominal muscle, two-arm It swings forward, rapidly at sitting posture, upper body continuation is anteflexion, and two hand haptic element faces bow, are then reduced into sitting posture, can so carry out Load stomach workout.Such structure design, the structure and position advantage for taking full advantage of backrest plate itself are wanted in conjunction with movement Neck, not only loaded weight is easy to operate, safe, but also can satisfy most of training with the multiple dumbbell plates of on-demand loading The need of exercise of person.

Further, the limit assembly is the groove-like structure that section is in U-shape, and two cell walls of the limit assembly offer Limit hole, to form multiple opposite limiting tooths.Such design can arbitrarily be sat according to trainer's height situation The adjusting of plate height.

Further, the backrest plate hinge bar is two, and is hingedly connected at left and right sides of the top of column, a phase Pair limiting tooth in be equipped with gag lever post, the left and right ends of the gag lever post stretch out limit assembly two cell walls it is outer and with two sitting heights The free end of hinge bar is socketed, and is connected with support rod between the free end of two backrest plate hinge bars, the support rod Middle part is affixed with leg support bar.Such design, not only total is more firm, and the adjusting of seat plate height is more smooth, And limit effect is preferable.

Further, the outer wall of the leg pressing sleeve, supporting leg sleeve, seat plate and backrest plate, which matches, is arranged with cushion.In this way Design, leg, buttocks and the back of trainer can be allowed to be in state as snug as a bug in a rug, so that training process is more relaxed Clothes, design are more humanized.

Further, the loop bar offers multiple fixation holes, is inserted with T-shaped fixed pin in a fixation hole.In this way Design, the dumbbell plate that can be would sit idle for is temporarily stored on loop bar, and is fixed by the limit of T-shaped fixed pin, loads stomach workout Process is safer, avoids the occurrence of accident, and design is more humanized.

Further, the seat plate rear end face is fixed there are two semicircle blocky trunnion, and the backrest plate front end face is fixed with One semicircle blocky hangers, the hangers is inserted between two trunnions and hinged by pin shaft.Such design so that seat plate and Articulated structure between backrest plate is relatively simple, and backrest plate rotary course acts smooth without interference.

Further, the aperture position of the loading hole is radially integrally formed with multiple in the axial limiting being angularly distributed Block, for the inner wall one end of the axial limiting block integrally formed with radial limited block, the cover board is for plectane and radially integrated The quantity otic placode equal with axial limiting block is formed, the otic placode can be with the gap between two neighboring axial limiting block Match, the top surface of the cover board is integrally formed with cross handle.Such design can carry out cover board axially and radially dual Limit, to prevent dumbbell plate from deviating from out of loading hole, it is ensured that trainer's safety.

Further, the shoulder belt is two sections of telescopic bands, and one end of the telescopic band is connect with backrest plate, and the two of telescopic band A free end snaps connection.Such design can adjust shoulder belt at any time, make trainer according to the otherness of trainer's individual It is more comfortable, meet the need of exercise of more crowds.
