Description

Table tenning ball servicing machine

The utility model relates to a kind of sports goods, is specifically related to a kind of table tennis ball serving device.

The ball serving device that is adopted in China's table tennis training all adopts import equipment at present, this device adopts helical structure, processed complex, and cost is very expensive, structure is also quite huge, and must be fixed on a certain position when using, dismounting, maintenance all bother very much, simultaneously, its service placement flies away very much, control that can not be artificial, the normal only phenomenon of net that occurs, service has the phenomenon of interruption to take place often.

The purpose of this utility model is the defective that overcomes prior art, provides a kind of simple in structure, cheap, and the service performance is complete, stable and table tenning ball servicing machine easy and simple to handle.

The purpose of this utility model realizes by following technical proposal, it comprises the service case and supplies ball bucket two parts, establish an outlet at service case middle part, establish upper and lower flexible roller in it, two flexible rollers rotate in opposite directions, two buncher output shafts drive and rotate respectively, in service porch, case top, fix one and lead bulb; Be located at the top of service case for the ball bucket, the bottom installs one for the ball rotating disk, establishes one or more on this rotating disk and contains the ball hole, and it is corresponding with the case upper inlet of serving a ball to establish an outlet for ball bucket bottom; Bottom the service case, also be provided with a yaw device, can regulate service left and right sides drop point, service case or yaw bottom of device are established a bracing or strutting arrangement, front and back drop point during with the adjusting service.

The utlity model has following technique effect:

1, simple in structure, cheap, the utility model device adopts the micro-speed motor of buying easily on cheap and the market to be used as power, and can control respectively, because structure is very simple, uses maintenance all very convenient;

2, performance is complete stable, the ball that can send rotation under the top spin, chop, side top spin, side of varying strength by the rotary speed of regulating buncher and not revolve, but different changes is done in the drop point top to bottom, left and right, front and rear, can regulate simultaneously the service time interval, the table tennis fan who is very suitable for all ages and classes and varying level uses.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model is formed by service case 1 with for ball bucket 8 two large divisions, an outlet is established at service case 1 middle part, establish flexible roller 4 and following flexible roller 2 in it, two rollers are driven by last output shaft 5 and following output shaft 3 respectively and do opposite the rotation, go up flexible roller 4 and down flexible roller 2 appearances difference Bao Lvyi circle flexible material, can be sponge or other flexible material, two roller Edge Distances are about 2cm, can just hold a table tennis and pass through,, offer an inlet at the top side of service case 1, fix one below this inlet and lead bulb 9, lead bulb 9 and the ball that falls into from inlet can be imported to clamp between the two flexible rollers and throw away.Above service case 1, establish one for ball bucket 8, the bottom places one for ball rotating disk 6, as shown in Figure 2, offer one or more for ball rotating disk 6 upper peripheries and contain ball hole 18, containing ball hole 18 can a plurality of as required setting, to adjust serve speed, rotate by driving for ball rotating disk 6 for ball rotating shaft 7, this connects with a motor for ball rotating shaft 7.The utility model serve speed can be by two factor decisions, when supplying ball rotating disk 6 Sheng ball holes 18 hole counts fixedly, serve speed is by turn-knob control (not drawing among the figure) on the buncher, if adopt non-adjustable speed motor, then change for the number of containing ball hole 18 on the ball rotating disk 6 to reach the purpose of control serve speed.

The utility model is established an outlet for ball bucket 8 bottoms, this export center is aimed at for ball rotating disk 6 and is contained ball hole 18 axial lines, and it is corresponding with the inlet of offering on the service case 1, when in ball bucket endosphere falls into Sheng ball hole 18 and with confession ball rotating disk 6, going to 8 outlets of confession ball bucket, just fall between flexible roller 4 and the following flexible roller 2 through leading bulb 9 from service case 1 inlet, because two-wheeled turns round in opposite directions, under the drive of its frictional force, table tennis sends from 1 outlet of service case very fast, because the utility model two flexible rollers are driven by two different bunchers respectively, therefore, going up the flexible roller 4 and the serve speed of following flexible roller 2 and the rotary speed and the direction of ball can manually control with turn-knob, when two wheel speeds are identical, can send the ball that does not revolve; And work as two roller rotary speeies not simultaneously, because the frictional force effect, the ball that sends out can rotate up or be rotated down, and promptly regulates the ball that two roller rotating speed proportionings can obtain different rotary character.

The left and right sides drop point of ball for a change, the utility model is provided with a yaw device 10 in service case 1 bottom, it is by yaw seat 11, buncher 12 and dead man 13 are formed, service case 1 is shelved on the yaw seat 11, dead man 13 is L-shaped, one end is connected with buncher 12 output shafts, the other end is fixed on the yaw seat 11, when buncher 12 rotates, just drive dead man 13 and rotate, because dead man 13 is L-shaped and be fixed on the yaw seat 11, so yaw seat 11 is done left and right sides straight line slippage under the drive of dead man 13, the left and right sides drop point in the time of can changing service at any time.

Front and back drop point when serving a ball for regulating, the utility model is established a bracing or strutting arrangement 14 in yaw seat 11 bottoms, also can be directly arranged in service case 8 bottoms, this device is by base plate 15, fixed bar 16 and Adjustable bracing bar 17 are formed, fixed bar 16 and Adjustable bracing bar 17 all are fixed on base plate 15 back sides, when the height with Adjustable bracing bar 17 raises or reduces, base plate 15 can be inclined, thereby the placement that is sent can change with the inclined degree of base plate 15, thus the purpose of drop point before and after will reaching when adjusting service.
