Description

A kind of table tennis batting machine

Technical field

The utility model relates to a kind of sports exerciser or exercise device, relates to a kind of table tennis batting machine especially.

Background technology

Table tennis belongs to the technical ability project, the essential characteristic of its training is repetition, do not have certain number of repetition, the nerve pathway of formation condition reflection just is difficult to form the dynamic stereotype of consolidation, and by training technology and the tactics ability that is obtained, its essence is neural temporary connection, training is interrupted this nerve connections is weakened, and conditioned reflex is disappeared, and dynamic stereotype is destroyed, strengthen routinely basic training training so have only, could improve the accuracy and the quality of batting.And because table tennis is a kind of double motion, needs people's training mate or use service robot, and just can practise, and can't carry out training voluntarily and take exercise in a place that is enough to place billiard table.

In table tennis teaching, the exercise of table tennis can be divided into the free exercise exercise of not playing ball (again can the branch gimmick, footwork and both combination exercises) and the exercise (can be divided into the exercise of playing ball of appearing on the stage and not appearing on the stage) of playing ball, this wherein, part is played ball exercise as dig, wall such as is played at feel of the ball exercise can carry out separately, but push and block, when then must having people's training mate or use service robot, play such as drive or arcing circle just can carry out, for solving a last problem, a kind of table tennis exercising machine is disclosed among the CN2302821Y, it comprises support, an end of fixing spring or steel wire on this support, and the fixing table tennis of the other end of spring or steel wire.This kind table tennis exercising machine structure uniqueness, simple for production, be subjected to site influence little, utilize this table tennis exercising machine, do not need ladder player or service robot, but independent exercise, and the exercise of play such as push and block, drive or arcing circle is provided for the practitioner, provide useful help to strengthening movement pattern etc.But, this kind table tennis exercising machine does not use restraint fully to the motion of spring or steel wire, the freedom of movement of spring or steel wire is excessive, very easily generation is rocked or is rocked, under relative position, be difficult to find striking point on the ball accurately, and can not simulate the actual combat feel of table tennis fully, the user is difficult to impact the ball motion.In addition, in above-mentioned device, table tennis is fixed on the front end of spring or steel wire, impacts in the process and very easily breaks.

The utility model content

The purpose of this utility model provides a kind of table tennis batting machine, to solve the above-mentioned problems in the prior art.This kind table tennis batting function is simulated the actual combat feel of table tennis preferably, repeat batsmanships such as attacking driving, drive or arcing circle for the practitioner, the conversion that can also carry out footwork training and the action of different batsmanship when two batting machines are used is connected training, in addition, the characteristics that this kind batting facility have that occupy-place is little, need not plug-in in the use, therefore, this kind table tennis batting machine can the table tennis fan and the diligent learner of environment provide the condition of practising or taking exercise in order not have under battle conditions, make its maintenance and improve original various batsmanship ability.

The utility model adopts following technical scheme:

A kind of table tennis batting machine, comprise a base and be fixed in the elevating mechanism of this base top, it is characterized in that: the clip slot of upper fixed one fore-and-aft direction of described elevating mechanism, fix the mandrel two ends of a left and right directions in this clip slot, sheathed successively one first stage clip on this mandrel, the one swing sheet that can on front and back and left and right directions, swing and one second stage clip, one end of this first stage clip and second stage clip is resisted against on the swing sheet, the other end then is resisted against the inwall of clip slot, the fixedly connected projection in center of this swing sheet front end, the outer fixedly sleeved swing pipe of this projection; In position one torsion spring set is set separately on the described clip slot corresponding to this first stage clip and second stage clip outside, arranged outside one torsion spring of described torsion spring set, the two ends of torsion spring are separately fixed at a corresponding side of described clip slot, and the middle part of torsion spring then is pressed over described swing pipe rear side; One the 3rd stage clip is set in this swing pipe vertically, one end of the 3rd stage clip is resisted against described projection, then against an expansion link that has a chute, near the fixed-site one rivet two ends of front end, this rivet is located in the described chute other end slidably on the described swing pipe; This expansion link interval one Flexible element connects the lower end of a head bar, and the upper end of this head bar connects a ball arc sheet, and the front end of this ball arc sheet fixes one in order to place the cage of table tennis.

In the embodiment that recommends, be provided with a pair of in the described clip slot in order to offset the buffer of described swing sheet bump strength, this all is positioned at the pendulum radius of described swing sheet to buffer, and be separately positioned on before the described swing sheet and position afterwards, each buffer is by first stainless steel tube of end closure once, the buffer stopper that is bonded in the 5th stage clip in this stainless steel tube and is bonded in the 5th stage clip upper end forms, this stainless steel tube is fixed in the clip slot, this swing sheet is resisted against on the buffer stopper of anterior bumper, and this buffer stopper has a usefulness so that swing pipe and horizontal direction form the height of 47～48 degree angles.The bump strength that buffer produces when reducing the swing pipe swing, and reduce the generation of noise.
