Description

A kind of tennis is received exercising machine

Technical field

The present invention relates to technical field of sports apparatus, and in particular to a kind of tennis is received exercising machine.

Background technique

In recent years, body building project of the tennis as filter, to constitution, pleasant mental and body, the development intelligence for promoting people Power and the indomitable will and character of culture have good effect, thus are liked and participated in by more and more people.But due to net Ball is one and does not allow easy to get started sports events, and beginner often becomes because the ball of tennis is unfamiliar with during begining to learn It must be difficult to grasp every technology of tennis.During learning tennis basic fundamental, carrying out tennis sending and receiving training is one ten Point important process, conventional tennis are begun to learn in teaching, general to be swung the bat practice to student's release and student manually by coach Mode is realized, or is played tennis by tennis-exercising device to learn.But the present inventor has found after study, passes through religion Practice member to swing the bat practice to student's release and student manually, the coach's number needed in this way is more, accordingly will increase training organization Manpower instruction cost；And learned and played tennis by tennis-exercising device at present on the market, it is required every time in practice in this way Move tennis-exercising device to training place, but existing tennis-exercising device structure is more complicated, thus heavier-weight, it is very inconvenient It is mobile, extremely it is unfavorable for the teaching and popularization of tennis.

Summary of the invention

It is swung the bat practice to student's release and student manually for of the existing technology by coach, will increase training machine Structure manpower instruction cost, or played tennis by existing tennis-exercising device to learn, it will lead to mobile inconvenience, be unfavorable for tennis teaching The technical issues of with promoting, the present invention provide a kind of novel tennis ball and receive exercising machine.

In order to solve the above-mentioned technical problem, present invention employs the following technical solutions:

A kind of tennis is received exercising machine, including support principal post, crossbearer, rotation axis, contraction spring, supporting mechanism, elasticity branch Frame and tennis；Wherein, the elastic support is arc, and the tennis is fixed on one end of arc elastic bracket, the support Mechanism includes vertical supporting body and cross-brace body, and the vertical supporting body is equipped with the vertical chute, the cross-brace body One end is equipped with the sliding block that is closely slidably matched with the vertical chute, back to being additionally provided on the side of ground surface on the cross-brace body Mounting groove, the rotation axis is installed in mounting groove and the both ends of rotation axis are fixed on the cross-brace body of mounting groove two sides, The other end of the elastic support is fixedly connected with the connecting rod in the middle part of rotation axis and the arc of elastic support is back to ground surface, institute It states elastic support and is connect by contraction spring with cross-brace body close to one end of connecting rod, one end of the crossbearer is fixedly connected Vertical supporting body, the other end of the crossbearer are fixed on support principal post.

Further, multiple first permanent-magnet ferrites, institute are equipped with close to the surface of the cross-brace body of the contraction spring It states relative position on elastic support and is equipped with multiple second permanent-magnet ferrites opposite with the pairing of the first permanent-magnet ferrite and magnetism.

Further, the support principal post is equipped with prominent connecting column, and the other end of the crossbearer is equipped with recess connecting hole, The recess connecting hole is socketed on prominent connecting column, and is fastened with card on the outer surface of the crossbearer equipped with recess connecting hole Hoop, the place of fiting of two cyclic annular cuffs included in the clip are fastened by bolt, and the bolt for quadrangle or Five corner bolts.

Further, be additionally provided with the coating of entire bolt and the masking of cyclic annular cuffs on the clip, the coating with In the curved surfaces of smooth transition between the support principal post and crossbearer.

Further, the tennis receive exercising machine further include be installed on support principal post on photographic device and wireless transmission mould Block, the photographic device are used to obtain the practice data of trainer, and the wireless transport module is used for the practice information that will acquire Data are transmitted to administrative center.

Further, the photographic device is camera, and the wireless transport module is WiFi module or the wireless mould of Zigbee Block.

Compared with prior art, tennis provided by the invention is received exercising machine, in cross-brace body back to the side of ground surface Face is provided with mounting groove, and rotation axis is equipped in mounting groove, and the other end of elastic support and the connecting rod in the middle part of rotation axis are fixed The arc of connection and elastic support passes through contraction spring and cross-brace close to one end of connecting rod back to ground surface, elastic support Body connection is fixed with tennis on one end of arc elastic bracket, thus tennis is in far from ground under normal circumstances The position of side.When practitioner's batting carries out serving a ball trained, tennis will drive elastic support to rotate counterclockwise around rotation axis, when After tennis drives elastic support to rotate by a certain angle counterclockwise, due to the reaction force factor of contraction spring, tennis can be made fast Speed and stabilization is returned to initial position, achievees the purpose that trainer continuously receives practice；Meanwhile cross-brace is adjusted by sliding Position of the body in vertical supporting body upper hopper chute, can effectively adjust the height of cross-brace body in the vertical direction, so as to Preferably to meet the practice requirement of different height trainers.Therefore, tennis provided by the invention is received exercising machine, not will increase Training organization's manpower instruction cost；Meanwhile the support principal post in the present invention can be set as to the tennis column at court scene, that is, it incite somebody to action this The tennis that invention provides exercising machine of receiving is mounted on tennis court scene, non-because without moving to exercise device Often it is suitble to live tennis teaching and popularization.
