Volleyball Elbow Pad Corrector

Abstract

The invention provides a volleyball ball corrector for elbow flexion, which includes a main rotating part, a pulling device, two sets of arm fixing devices and two sets of telescopic devices; one end of two elastic bands of each group of arm fixing devices is respectively fixed on the semicircular arm through a fixing buckle. The end of the ring; the threaded sleeve of each group of telescopic devices is threadedly matched with the first screw rod; the arc top of each semicircular arm ring is fixed with two first mounting plates, and the threaded sleeve is fixed with the first rotating block, which is connected with the two second A mounting plate is rotatably connected; the other end of each first screw rod is fixed with two joint plates, and the main rotating part is rotatably connected with the two joint plates of the two sets of telescopic devices; the pulling device includes a spring and two second rotating blocks The top of each fixed plate is fixedly provided with two second mounting plates, each second rotating block is rotationally connected with the two second mounting plates, and the two ends of the spring are respectively fixed to one end of the two second rotating blocks. On the premise of not restricting the various movements of the trainer, the device can assist in the correction of elbow flexion and kicking the ball.

Description

technical field [0001] The invention relates to the technical field of training equipment, in particular to a volleyball elbow-bending ball corrector. Background technique [0002] Cushioning is one of the basic techniques of volleyball. It is a hitting technique that makes the incoming ball bounce off the pad hitting surface through the arm's attack action on the basis of the whole body's coordination and force. And the main method of dealing with various difficult balls is the basis for ensuring one's own offense. When cushioning the ball, you must have the correct preparation posture, reasonable batter shape, accurate batting action and reasonable hitting position, and adjust the appropriate force angle between the arm and the ground in order to achieve a good cushioning effect. However, beginners often unconsciously adopt the wrong action of bending the elbow to kick the ball, which affects the stability and accuracy of the kick. [0003] At this stage, volleyball oft...

However, beginners often unconsciously use the wrong action of bending the elbow to kick the ball, which affects the stability and accuracy of the kick.

[0003] At this stage, volleyball often adopts manual one-to-one correction method for elbow flexion, which consumes a lot of energy of the coach; if the traditional mechanical structure is used to force the elbow to be limited, it will easily affect the trainer's movement performance, and it is also very easy to make the training difficult. cause harm
