Block, lead screw, elevating lever and link block are constituted；The motor is sequentially connected by gearbox and the lead screw bottom end；The cover
It is located above casing, the upper bearing (metal) is located in cover, and the lower bearing is located at casing lower part, and the screw both end is respectively provided at
In upper bearing (metal) and lower bearing, the sliding block is screwed onto on lead screw and is passed through by the lead screw；The internal side of shell wall, which is equipped with, to be supplied
The sliding slot that sliding block moves up and down；The elevating lever passes through the bottom of the cover and elevating lever to be connected on the sliding block；It is described
The link block is equipped at the top of elevating lever；Cross bar is equipped between the montant top and the link block；The cross bar is equipped with
Two spacing rings in left and right, are equipped with hanging ring between two spacing rings, and the hanging ring is connected with the net for filling vollyball by lifting rope
Bag.
The vollyball of this physical education is practised a ball game device, and the principle of lifting is：Motor passes through torque after gearbox speed change
Increase, gearbox drives lead screw rotation, on the other hand one side of sliding block on lead screw is limited in again with due to being spirally connected with lead screw
In sliding slot, therefore sliding block can move up and down, and drive elevating lever to move up and down using sliding block, be achieved in the fortune up and down of link block
Dynamic, since cross bar one end follows link block to move up and down, the other end is free end, because the montant being connected can be in casing seat
Freely activity（When lock-screw unclamps）, after being adjusted to rational position, motor is stopped, lock-screw locking, such cross bar
It just secures, student can be in the vollyball in impact mesh bag below cross bar, to achieve the purpose that practise a ball game.
Further embodiment is：Described sleeve pipe seat four and is spaced apart totally in 90 degree.
The vollyball of physical education designed by the utility model is practised a ball game device, its advantageous effect is：Pass through body of rod liter
The cross bar of its all both sides can be raised up to desired height by falling unit, and student can be in the row in impact mesh bag below cross bar
Ball reaches knowing ball-sense, practices the purpose of slam-shot.It is practised a ball game device, need not often be picked up using the vollyball of this physical education
Ball can adjust batting height according to not of the same grade section of height, effectively improve efficiency of teaching.
