Abstract

The utility model relates to a table tennis ball pitching machine of which a ball storage device is connected with a seat through a ball inlet passage. The seat is provided with a driving device and a rotatable ball outlet passage. A shifting fork mechanism and a bearing seat for supporting table tennis balls are arranged inside the seat. The seat is installed on a supporting frame, and can rotate round the supporting frame. A swing mechanism is arranged between the seat and the supporting frame. The utility model has the advantages of more functions and convenient operation, and can optionally adjust the position of the point of fall. Conveying the balls with the shifting fork mechanism, the utility model can avoid the occurrence of ball blocking.

Description

Table tenning ball servicing machine

The utility model relates to a kind of table tenning ball servicing machine

The present domestic table tenning ball servicing machine majority that uses is imported product, because this product design is when launching the ball angle, refer generally to fix on table top 1/2,2/3 or 3/4 etc. fix on 2, table tennis drop point site dullness, and card ball fault happens occasionally in the service process, uses extremely inconvenience.

The purpose of this utility model is to provide a kind of multiple functional, easy to use table tenning ball servicing machine.

The purpose of this utility model is achieved in that

A kind of table tenning ball servicing machine is characterized in that by pedestal Chu Qiuqi, the goal passage, transmission mechanism, shifting fork mechanism, go out the ball passage, friction pulley, swing mechanism, support is formed, and wherein stores up the ball device and links to each other with pedestal by the goal passage, transmission mechanism is housed on pedestal and rotatingly goes out the ball passage, shifting fork mechanism and the supporting base that is used to support table tennis are housed in pedestal, pedestal is then rack-mount, and can rotate around support, is provided with swing mechanism between pedestal and support.

Aforesaid service robot is characterized in that shifting fork mechanism is made up of cam, shifting fork bar, regulating spring, and cam is installed on the drive link, and shifting fork bar is fixed by fulcrum, and regulating spring is contained between shifting fork bar and the pedestal.

Aforesaid service robot is characterized in that pendulous device by eccentric wheel, eccentric adjusting screw, fixed head, spring is formed, and eccentric wheel is contained in the lower end of drive link, when drive link rotates, eccentric wheel rotates, under fixed head and eccentric effect, and the relative support swing of pedestal.

This reality has the novel multiple function that has, and can send the ball of eight kinds of different rotary, and easy and simple to handle, it can regulate the drop point site of ball arbitrarily, and this just adapts to than being easier to the fan of different levels level, and this equipment use shifting fork mechanism release, avoided card ball fault to occur.

The utility model is applicable to specialty or amateurish table tennis training, not only the sportsman of professional sports team can grasp, and the men and women, old and young of school, office, public place of entertainment are fit to use, and it can help you to improve the table tennis technology level, increases the enjoyment of people to this motion of table tennis.

Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation

Fig. 1 is a structural representation of the present utility model

Fig. 2 is that E-E of the present utility model is to cut-away view

Fig. 3 is the utility model partial enlarged drawing

Fig. 4 is an outside drawing of the present utility model

The utility model stores up ball device 2, goal passage 3 by pedestal 1, transmission mechanism 4, shifting fork mechanism 5 goes out ball passage 6, friction pulley 7, swing mechanism 8, support 9 is formed, wherein storing up ball device 2 links to each other with pedestal 1 by goal passage 3, transmission mechanism 4 is housed on pedestal 1 and rotatingly goes out ball passage 6, shifting fork mechanism 5 is housed in pedestal 1 and is used to support the supporting base 10 of table tennis, 1 of pedestal is installed on the support 9, and can rotate around support 9, between pedestal 1 and support 9, be provided with swing mechanism 8.

Transmission mechanism 4 is by motor 11, worm and gear transmission 12, drive link 13 is formed, motor 4 links to each other with worm screw, and worm gear links to each other with drive link 13, and the last top of drive link 13 links to each other with driving lever 14 in the storage ball device 2, the middle part links to each other with cam 15 in the shifting fork mechanism 5, the lower end links to each other with eccentric wheel 16 in the swing mechanism 8, and after motor rotated, power imported storage ball device 2, shifting fork mechanism 5 and swing mechanism 8 respectively into by drive link 13.

Shifting fork mechanism 5 is made up of cam 15, shifting fork bar 16, regulating spring 17, cam 15 is installed on the drive link 13, shifting fork bar 16 is fixing by fulcrum 18, regulating spring 17 is contained between shifting fork bar 16 and the pedestal 1, when cam 15 rotates, drive shifting fork bar 16 swings, under the effect of elastic force, will deliver to out ball passage 6 by the ball that goal passage 3 falls.By friction wheel 7 ball is dealt into the other side's table top again.

Pendulous device 8 is by eccentric wheel 22, eccentric adjusting screw 19, fixed head 20, spring 21 is formed, eccentric wheel 22 is contained in the lower end of drive link 13, when drive link 13 rotated, eccentric wheel 22 rotated, owing to be rotary between pedestal 1 and the support 9, under the effect of fixed head 20 and eccentric wheel 22, pedestal 1 relative support 9 swings, like this, the ball that service robot sent has different drop points.When the angle of swing need reduce, turn eccentric off-centre down and get final product, regulate the eccentric screw in the swing mechanism clockwise, the angle of the ball that sends is just big, and the counterclockwise ball angle of sending of regulating is just little, until fixed point.

Friction pulley 7 is contained in out on the ball passage 6 by independent driven by motor, and when rotating out ball passage 6, the angle of friction pulley 7 changes, and just can send different screws.

The utility model is when work, and the table tennis in the storage ball device 2 is stirred by driving lever 14, enters in the pedestal 1 by goal passage 3, and, at this moment, respectively ball is sent into out ball passage 6 by shifting fork mechanism 5 by supporting base 10 supportings, friction pulley 7 by rotation at a high speed quickens again, and ball is dealt into the other side's table top.

The utility model adopts rushes the open type design, lucid and lively and innervation is arranged, and cooperates the glass fibre reinforced plastics casing of different colours, will obtain liking of table tennis fan.
