Abstract
The invention discloses a kind of javelin training aids, include left and right column, and the adjustable pulley yoke in position is equipped on left column, pulley is equipped on pulley yoke；On left column clump weight is equipped with positioned at the lower section of pulley；Right column includes interior slide bar, and adjustable for height outer sliding sleeve is sliding combined on interior slide bar, and stone dead wire is hinged on the outer sliding sleeve, and the other end of stone dead wire is moved left column position to and is fixedly connected on clump weight after being wrapped over pulley；Sliding sleeve is set with buffer stopper arranged side by side close to right column Slideslip, spring is fixedly connected between adjacent buffer stopper equipped with javelin corresponding with javelin weight simulation set, stone dead wire on the stone dead wire.Floor space of the present invention is small, low to site requirements, after use, dismountable moving；Have the advantages that self-return, safety coefficient are high；Supplemental training can be effectively improved, training more standard is made, because when the angle adjusted only meets, what could be thrown is farther, and it is very fast that sleeve strikes buffer substrate tablet rebound seating velocity.When there is deviation, when can meet compared with resistance when sleeve can occur that longitudinal axis effect of exerting oneself is poor, and return is slow and arrives and pauses along steel wire rope vertical tremor.
Description
Technical field：
The present invention relates to sports movement training apparatus, relate generally to a kind of javelin training aids.
Background technology：
Currently, domestic throwing circle coach is mainly had using special throwing means：Different weight rubber ball, glueballs are thrown,
Small iron ball weighs the instruments such as javelin, medicine ball to improve the special throwing ability of sportsman's javelin.The throwing ability of sportsman is improved
Positive effect is played, as science and technology is being constantly progressive, the exercising device research and development of special projectization are in budding state, Hao Duozhuan
The exercising device of itemization still leans on import and introduction.Based on this, the javelin of this research whips training aids and is intended to abundant throwing training
Means.
Traditional javelin training court requires place larger, and the javelin thrown away in the training process will be got back,
It wastes time, reduces the frequency of training of javelin.In addition, javelin is dangerous when traditional training, it is susceptible to accident and hurts sb.'s feelings.
Invention content：
The object of the invention is exactly to provide a kind of javelin training aids to make up the defect of prior art.
The present invention is achieved by the following technical solutions：
A kind of javelin training aids, it is characterised in that：Include left and right column, the adjustable cunning in position is installed on left column
Wheel carrier is equipped with pulley on pulley yoke；On left column clump weight is equipped with positioned at the lower section of pulley；Right column includes interior slide bar,
It is sliding combined with adjustable for height outer sliding sleeve on interior slide bar, stone dead wire is hinged on the outer sliding sleeve, the other end of stone dead wire is drawn
It is fixedly connected on clump weight to left column position and after being wrapped over pulley；Sliding sleeve is equipped with and javelin weight on the stone dead wire
Corresponding javelin simulation set, stone dead wire are set with buffer stopper arranged side by side close to right column Slideslip, consolidate between adjacent buffer stopper
Surely it is connected with spring.
A kind of javelin training aids, it is characterised in that：The left column top is equipped with speed reducer, and the output shaft of speed reducer is
Longitudinal hollow shaft, the external part of the output shaft are fixed with concentric nut, lead screw, screw lower end are installed in the nut
Output shaft across speed reducer stretches out outside speed reducer, and the pulley yoke is lifted on the external part of lead screw.
A kind of javelin training aids, it is characterised in that：Positioned at the portion of the lower section of pulley yoke on the both sides side plate of the left column
Position has cannelure, and hand-held rod is sliding combined in cannelure, and clump weight, the stone dead wire connection are lifted on hand-held rod
On the hand-held rod.
A kind of javelin training aids, it is characterised in that：The input shaft of the speed reducer shakes control rotation by handwheel.
A kind of javelin training aids, it is characterised in that：The stone dead wire is skewed, and angle of inclination is 29 °.
A kind of javelin training aids, it is characterised in that：It is fixedly connected with crossbeam between at the top of the left and right column.
A kind of javelin training aids, it is characterised in that：The section of interior slide bar, outer sliding sleeve in the right column is rectangular.
The present invention makes it integrally erect before use, left and right column is first fixed on ground.Then according to sportsman's body
The both ends of stone dead wire, are adjusted to the corresponding position of left and right column by height, and it is 29 ° to keep the angle of inclination of stone dead wire.Also want root
According to the strength size of sportsman, suitable javelin simulation set is selected（500g, 600g, 700g, 800g, 1000g etc.）It is replaced.
It adjusts position of the stone dead wire on right column and only needs to adjust outer sliding sleeve in the position of interior slide bar, realize adjustment
The purpose of stone dead wire right end height.Position of the stone dead wire on left column is adjusted, then needs to shake handwheel, passes through feed screw nut's original
Reason, lead screw move up and down, and band movable pulley rack moves up and down, and realizes the purpose of adjustment stone dead wire left end height.
In the training process, javelin simulation set is practiced as javelin by sportsman, and javelin simulation set is come out by throwing
Afterwards, it under the action of buffer stopper, stops slowly and slowly slides back to left end along stone dead wire.The trouble for picking up javelin is eliminated,
Also avoid that there is a phenomenon where injuries to personnel to occur.
Advantages of the present invention：
Floor space of the present invention is small, low to site requirements, after use, dismountable moving；With self-return, safety system
The high advantage of number；Supplemental training can be effectively improved, makes training more standard that could be thrown because when the angle adjusted only meets
That throws is farther, when having deviation, when can meet compared with resistance and arrive and pause；Connection is reliable, and column bottom is fixed with big bottom plate, big bottom plate
It is connect with surface dilation screw, can also add heavier mass pressure upper.Lead between crossbeam and column and locked with fixed seat and bolt,
Multiple-protection, it is ensured that safe and reliable.Steel wire rope is convenient for changing, and javelin simulation set changes the outfit simple.Due to selecting reducer with big speed ratio,
The clump weight of lifting will not glide, thus relatively safety.
