Abstract
The invention relates to sports equipment, in particular to an auxiliary training aid for a lead ball. The auxiliary training aid is characterized in that: four support circular tubes are welded below a sliding bush (8); four universal wheels are welded below the four support circular tubes respectively; an included angle between the sliding bush (8) and a horizontal plane is 38 degrees; a liquid crystal screen (7) is connected below the sliding bush; a hollow lead ball (5) is connected to the lowermost end of a linear optical axis (9), and is provided with a cross-shaped countersunk head screw; lead powder can be filled into or poured out of the hollow lead ball (5) by opening the cross-shaped countersunk head screw; a semicircular bent tube (4) is welded on the hollow lead ball (5); and a lead ball is welded at the lowermost end of the semicircular bent tube (4). Through the auxiliary training aid, the lead ball can be thrown at an original place in back and lateral directions, and can be thrown in back sliding and lateral sliding ways.
Description
Technical field
The present invention relates to a kind of sports equipment field, be specially the complementary training aids of shot.
Background technology
A kind of license notification number CN201389319Y, disclose the complementary training method of a kind of shot, its advantage is the complementary equipment providing a kind of shot training to practitioner, it is the equipment that a kind of technicality training shot is finally had an effect, its shortcoming be in original place dorsad, side direction and slide-pace shot put complete skill training time, this apparatus cannot be trained, for this reason, explore a kind of can experience of study shot complete skill training equipment.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the complementary training aids of a kind of shot, changing traditional shot training method, design the equipment of the complementary training of a kind of technicality shot.Practitioner is made to grasp shot technology fast.Effectively prevent the accidents such as shot injury.
The technical solution adopted for the present invention to solve the technical problems is: the complementary training aids of shot, primarily of universal wheel 1, supports pipe 2, shot 3, semicircle bend pipe 4, hollow shot 5, first damping spring 6, liquid crystal display 7, sliding sleeve 8, straight optical axis 9, second damping spring 100 part formation.It is characterized in that: the length of described sliding sleeve 8 is 0.5 meter, the length of straight optical axis 9 is 1.8 meters, and the second damping spring 10 length is 0.2 meter, and the first damping spring length is 0.1 meter, and the length that straight optical axis 9 slides up and down inside sliding sleeve 8 is 1 meter.The diameter of semicircle bend pipe 4 is 1 meter.The diameter of hollow shot 5 is 0.1 meter.
Described sliding sleeve 8 is welded with four below and supports pipe, supports below pipe be welded with four universal wheels respectively at four.
Described sliding sleeve 8 is 38 degree with the angle of horizontal plane.Liquid crystal display 7 is connected with below sliding sleeve, hollow shot 5 is connected with bottom at straight optical axis 9, hollow shot 5 there is crossed countersunk head screw, open crossed countersunk head screw, can filling lead powder therein, also can pour out lead powder, hollow shot 5 be welded with semicircle bend pipe 4, is welded with shot bottom at semicircle bend pipe 4.
There are two linear bearings described sliding sleeve 8 inside, and straight optical axis 9 is enclosed within the linear bearing of sliding sleeve 8 inside, and straight optical axis 9 can freely up and down slide inside sliding sleeve 8, also can linearly optical axis longitudinal axis.
The first described damping spring 6 in sliding sleeve 8 bottom by resilient, the pressure data of generation is presented on liquid crystal display.There is the second damping spring 10 straight optical axis 9 upper end, and when straight optical axis 9 slide downward, the second damping spring 10 slips down to sliding sleeve position and completes resilient.
The invention has the beneficial effects as follows: the complementary training aids of shot, provides a kind of training device to practitioner, timely and accurately from the related data of liquid crystal screen display training, the effect of training supervision can be reached.Effectively prevent the generation of injury accident in shot training.
Therefore tool of the present invention has the following advantages: this physical culture equipment structure is simple, easy to make, easily popularizes use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is perspective view of the present invention.
Fig. 2 is stereochemical structure of the present invention mark schematic diagram.
In figure: 1, universal wheel, 2, support pipe, 3, shot, 4, semicircle bend pipe, 5, hollow shot, the 6, first damping spring, 7, liquid crystal display, 8, sliding sleeve, 9, straight optical axis, the 10, second damping spring.
Detailed description of the invention
Be below preferred example of the present invention, therefore do not limit protection scope of the present invention.
Embodiment: with reference to shown in Fig. 1, Fig. 2, for right hand holding, shot 3 is placed on neck clavicle nest place by practitioner, health in advance back stutz to back-putting place, the design of semicircle bend pipe 4, spatial design when being rotated by human body is inner at semicircle bend pipe, along with the back stutz in advance of health is to dorsad, straight optical axis 9, along sliding sleeve 8 slide downward, does not affect the performance of action and technology.This apparatus can do original place dorsad, side direction throw shot, also can do dorsad sliding steps, side direction sliding steps throw shot.But rotary Shot Put Techniques relative complex, seldom has beginner to train this technology, so this device design does not consider rotary Shot Put Techniques (hereby illustrating).The first described damping spring 6 in sliding sleeve 8 bottom by resilient, the pressure data of generation is presented on liquid crystal display.There is the second damping spring 10 straight optical axis 9 upper end, and when straight optical axis 9 slide downward, the second damping spring 10 slips down to sliding sleeve position and completes resilient.Described sliding sleeve 8 is 38 degree with the angle of horizontal plane, meets the angle that shot is sold.Liquid crystal display 7 is connected with below sliding sleeve, hollow shot 5 is connected with bottom at straight optical axis 9, hollow shot 5 there is crossed countersunk head screw, open crossed countersunk head screw, can filling lead powder therein, also can pour out lead powder, hollow shot 5 be welded with semicircle bend pipe 4, is welded with shot bottom at semicircle bend pipe 4.There are two linear bearings described sliding sleeve 8 inside, and straight optical axis 9 is enclosed within the linear bearing of sliding sleeve 8 inside, and straight optical axis 9 can freely up and down slide inside sliding sleeve 8, also can linearly optical axis longitudinal axis.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.The part of the not detailed description of the present invention is known technology.
