Abstract

The utility model provides an exerciser for pommel horse, which is a tool for guiding gymnasts to correctly grasp the full turn motion and the swivel motion of the pommel horse. The utility model is characterized in that a motor is arranged on the base of the exerciser for pommel horse; the rotary speed of the motor is regulated by a speed regulation controller; a transmission mechanism drives a rotary disk to rotate to make a U-shaped bracket and a foot ring which are fixed on the rotary disk rotate synchronously; thus, the gymnasts are helped to correctly grasp the technique substance of the full turn motion and the swivel motion of the pommel horse; the effects of straight body, flat foot walking, steady supporting, big amplitude, even rhythm, and short training time are reached. The utility model is suitable for the gymnastics training of universities, middle schools, and primary schools.

Description

Exerciser for pommel horse

This practical correct instrument of holding Pommelled horse giant hip circle and turning motion that supports of a kind of gymnast of guiding that provides belongs to gymnasium apparatus.

The pommel horse training is one of project of the most difficult training in the gymnastics 6 combined event.The gymnastics coach generally adopts various supplemental training apparatuses to train both at home and abroad at present, and what have trains with acnemia goat, mushroom goat, acnemia pommel horse, goat Pommelled horse giant hip circle trainer etc.Nearly all be that the coach promotes the sportsman and rotates, the backward training method of this forced labour is difficult to reach the bleeding edge of contemporary world pommel horse.

The purpose of this utility model provides a kind of pommel horse training airplane, helps the gymnast correctly to support the technical key point of holding Pommelled horse giant hip circle and turning the motion.Reach that health is straight, pin walk flat, support requirement steady, that amplitude is big, rhythm is even.

The pommel horse training airplane, mainly form by critical pieces such as support, motor, adjustment controller, worm gear, worm screw, clutch sleeve, U-shaped support, semi-circular bracket, rotating disk, pommel horse, saddle ring, pin rings.Its structure is that a motor is housed on the support, adjust motor speed by adjusting controller, motor drives worm screw by pulley concial disk, and meshing worm gear on worm screw is rotated together, and the worm gear internal diameter digs huge groove, be matched with clutch sleeve, I-shaped circular groove is made in the clutch sleeve upper end, is clipped by clutch fork, and clutch fork is by being bolted to (movingly) on the rotating disk, two arc round bars of welding above the clutch fork, dress Clutch Control plate on the arc round bar.Also weld a clutch lever in the middle of the clutch fork and extend U-shaped support tail end, the dress clutch handle is used.Pin ring support seat and semi-circular bracket also are equipped with in U-shaped support rear place, dress pin ring on the semi-circular bracket.The U-shaped support is to be formed by steel tube bending, is fixed in the bracket groove by eccentric clamping lever, and bracket groove is fixed on the rotating disk by screw.

The utility model is transformed on the basis of original goat, pommel horse training aids.It mainly is to adjust motor speed by speed setting controller, drives rotating disk, makes the pin ring that is fixed on the rotating disk do to rotate synchronously.Help the sportsman to give intensive training, promote the sportsman Pommelled horse giant hip circle according to the technical key point of pommel horse, the technical ability of body twist, skill, skilled, until consolidating till typing handles very skillfully, shorten the pommel horse training time more than three times.

Fig. 1, be pommel horse training airplane front view.

Fig. 2, be worm gear, worm screw mansion pseudosection.

Below in conjunction with Fig. 1 detail its structure and operation principle are described.This pommel horse training airplane is made up of support (1), motor, speed setting controller, worm gear (24), worm screw (25), clutch sleeve (8), U-shaped support (12), semi-circular bracket (16), rotating disk (10), pommel horse (22), saddle ring (21), pin ring critical pieces such as (17).

Support (1) is to be intersected to be welded on the disk iron plate by four channel-section steels to form.Motor is fixed on the support (1) by screw, covering motor by dome shaped cover (2), dome shaped cover (2) is fixed on the support (1) by screw, adpting flange (5) is welded at weldering adpting flange seat (3), worm gear post (4) two ends respectively on dome shaped cover (2) top, the upper end is fixed on the worm gear case (7) lower end adpting flange (3) by screw.And for example shown in Figure 2, worm gear case (7) lining is horizontal is adorning worm screw (25), and worm screw (25) both sides are covered with by bearings, supporting cover, are fixed on the worm gear case (7) by screw, load onto belt pulley and belt (6) at the tail end of worm screw (25) then, use for connecting motor pulley.And at the side of worm screw (25) assembling worm gear (24), assembling by bearing, the worm gear internal diameter digs huge groove, the huge groove on the engagement clutch cover (8).I-shaped circular groove is made in clutch sleeve (8) upper end, is clipped by clutch fork (9), and clutch fork (9) is gone up (movingly) by being bolted to rotating disk (10).Welding two arc round bars (19) above the clutch fork (9), arc round bar (19) is gone up dress Clutch Control plate (20), and insurance is used during for training.Also weld a clutch lever in the middle of the clutch fork (9) and extend U-shaped support (12) tail place, and clutch handle (14) vertically is installed, usefulness stops operating during for the coach.Clutch lever is controlled on the U-shaped support (12) by eccentric clamping lever (11), be equipped with also on the U-shaped support (12) that pin ring support seat (13), pin ring support seat (13) are gone up welding two steel pipes (15), semi-circular bracket (16) is contained in steel pipe (15) internal diameter, fix by adjusting screw.Semi-circular bracket (16) goes up dress pin ring (17).Pin ring (17) is by interior ring, outer shroud, and the centre is made up of ball.U support (12) is installed in the bracket groove (18), and is fixing by eccentric clamping lever (11), can adjust elongating or shortening of U-shaped support (12).Bracket groove (18) is to be fixed on the rotating disk (10) by screw.Rotating disk (10), centre are that a block plate, cylindrical are to be welded by angle steel.Tubing string of welding in the middle of the rotating disk (10), tubing string scurry logical clutch sleeve (8), worm gear case (7), worm gear (24), worm gear post (4), tubing string lower end by bearing arrangement under worm gear post (4), rotating disk (10) is rotated and support and use.

Saddle ring (21) is to be fixed on the pommel horse (22) by screw, pommel horse (22) is to be fixed on the fixed disk (23) by screw, support bar of welding in the middle of the fixed disk (23), support bar is scurried logical rotating disk (10) and tubing string, directly extend under the worm gear post (4), be fixed on the dome shaped cover (2) by nut.

Adjusting controller, is by speed regulator (transformer), compositions such as wheel ondoscope and electronic calculator.Be to buy existing electric equipment, needn't have talked.

Using method: before the start sportsman's both hands just supportting or back brace on saddle ring, both legs close up and put in the pin ring, health is tightened and is stretched, the coach is according to sportsman institute masterful technique degree then, adjust motor speed, starter motor just can carry out wheel and the training of the motion of turning.Should should slow down earlier during shutdown and afterwards shut down by slow to fast during start.
