Abstract

The utility model relates to a training simulator for throwing discus, belonging to technical field of the exerciser manufacturing. The utility model mainly comprises a base, an upright post, a dip angle pull rod, a swivel, a training hand shank, wherein the upright post is vertically fixed on the base, two ends of the inner loop of the swivel are respectively connected with the upper of the upright post and the middle lower surface of the inner loop of the swivel through the adjustable pedestal and also are hinged with a shaft pin on the upper extreme of the dip angle pull rod through a supporting saddle, the lower extreme of the dip angle pull rod is hinged with the base through a bolt, the training handle or the simulated discus is fixed on the supine surface of the external swivel through linear slider and a vertical shaft of the slider. When in use, firstly according to the height of the athlete, the entire height of the swivel should be adjusted, the dip angle of the swivel should be adjusted through the adjustability of the dip angle pull rod and the training handle of the proper type should be replaced, the athlete standing on the pedal of the inner of the swivel holds discoid handle in the hands and uses the gesture of throwing the discus to continuously energize towards fore upward to rotate the swivel and repeatedly practices the partial muscle group of the sling movement. The utility model has the advantages of reasonable design, convenient utilization and high training efficiency.

Description

A kind of throwing discus simulation trainer

Technical field

Utility model relates to a kind of throwing discus simulation trainer, belongs to novel technical field of manufacture of sports.

Background technology

The sportsman is when carrying out the training of throwing discus, and the discus that throwing goes out need be collected and transport usefulness again back, and training effectiveness is low, and occupied ground is big, poor stability.

Summary of the invention

Utility model is at the deficiencies in the prior art, and a kind of reasonable in design, easy to use, angle of shot, discus sports-training apparatus that dynamics is adjustable are provided.

The purpose of utility model is achieved through the following technical solutions: a kind of discus sports-training apparatus, mainly form by base, column, inclination angle pull bar, change and training handle, wherein, the column vertical fixing is on base, the two ends of ring are connected in the column upper end by adjustable pedestal respectively in the change, the middle part lower surface of ring in the change, be articulated in pull bar upper end, inclination angle by bearing and pivot pin, pull bar lower end, inclination angle is hinged by bolt and base, and training handle or simulation discus are fixed in the upper surface of outer change by the vertical shaft on linear slider and the slide block.

Described column is the hollow steel pipe structure, is provided with the groove towards change in the steel pipe upper end, and steel duct is provided with the adjustable pedestal elevating drive mechanism that feed screw nut is formed.

Described adjustable pedestal is T-shaped, is enclosed within the steel pipe, studs with on the short tube of nut to stretch out one section crossbeam, and crossbeam passes from the groove of steel pipe upper end, and nut cooperates with leading screw, and the worm-and-wheel gear that leading screw passes through the bottom is connected with drive motors.

Two annulus that described change is nested and can keeps sliding relatively inside and outside being, between the inside and outside annulus ball and locating slot are arranged, interior ring is retainer ring, be fixed on the column by adjustable pedestal, outer shroud is a slip ring, can freely rotate on interior ring, in order to regulate rotary resistance, interior ring is provided with adjustable damping brake gear.

Described adjustable damping brake gear is made up of with the brake block on the nested jackscrew the adjustable jackscrew on the ring in being fixed in, when tightening jackscrew, brake block is near the outer shroud that rotates, strengthened and the outer shroud of relative motion between frictional force, rotary resistance is strengthened, otherwise the power of then reducing friction makes it to rotate flexibly.

Pull bar lower end, described inclination angle is articulated in base upper surface, and the upper end is articulated in the lower surface of clamping rings by bearing and pivot pin, and by regulating distance between inclination angle pull bar and the base, the overall inclination angle of adjustable turn over ring is to adapt to athletic training requirement.

Described training handle is fixed in the upper surface of change outer shroud by chute and vertical shaft, and the handle profile can be imitated the discus of different model, can use according to the training need transposing.

During use, at first start direction switch, by rising and falling of adjustable pedestal according to sportsman's height, adjust the whole height of change, by adjusting the inclination angle pull bar, adjust the change inclination angle again, change the training handle of suitable types, the sportsman stands on the interior pedal of change, and grip rail pie handle constantly firmly rotates change to the front upper place with the posture of the discus of dishing out, can temper the local muscle group of sling movement repeatedly, have reasonable in design, easy to use, the training effectiveness advantages of higher.
