Description
Technical field
The utility model is related to Volleyball Teaching apparatus fields, and in particular to a kind of volleyball smash teaching hanging ball device.
Background technology
Traditional volleyball smash teaching aid is to install arm on a fixed or movable column, and vollyball is suspended in midair
It is used for teaching in scheduled height, two arms is at most installed for two students in each column while being used, it otherwise can phase
Mutually interference, utilization rate is not high, needs to prepare to cover this teaching aid to meet several students use of a team, in non-religion more
A large amount of space is occupied between class hour.
Application publication number is the Chinese invention patent application of 103041563 A of CN, discloses a kind of suspended-type movable row
Ball spiking training device sequentially passes through a cable on two side frames in use, arranging parallel cable in venue overhead
Grooving among carrying roller and worm gear transmits torque to worm gear, at the same time by motor-driven main shaft by geared worm
Torque is forwarded to carrying roller by the transmission gear meshed together, is held at monosymmetric two Duis by motor-driven main shaft
Under roller and the collective effect of worm gear so that volleyball drop shot training device of the invention moves to reach specific bit in volleyball court overhead
It sets, when static, due to the latching characteristics of worm gear device so that training device is fixed, quiet by the Ball for training of cable suspension
Only rest in designated position.It has a disadvantage in that：The suspension cable of Ball for training is not suitable for too long, also limits the height of cable,
If cable is suspended on always above venue, the use of venue section at other times is would interfere with, if only being hung in training
Cable, then cable is not suitable for too slightly, otherwise suspension difficulty being significantly increased because of too heavy again, but its too thin intensity of cable
It again can be weaker；Spiking can apply Ball for training powerful active force, can make online in the originally rack with suitable weight
It is vibrated on cable, Ball for training needs longer time that could restore static to be trained next time, and training interval is longer, and shakes
It can make cable stretcher strain, influence service life；In addition, a Ball for training, the increasing of rack quantity can only be suspended in midair in each rack
The deflection of cable can not only be increased by adding, but also can generate interference because of mutual vibration, and Ball for training is made to be more difficult to restore static.
Invention content

The intensity that longitudinal pedestal can also be improved generates vibration effect training interval when preventing from training.
The further scheme of the utility model is that the coil winding machine of winding lifting rope, coil winding machine tune are equipped on the arm
The height for saving lifting rope, further increases the height-adjustable range of Ball for training.
The further scheme of the utility model is that the lifting rope is stretch cord, and what stretch cord absorption Ball for training was subject to rushes
Power is hit, Ball for training is made to be easier to restore static under the effect of gravity, further shortens training interval.
The further scheme of the utility model is that the extension and contraction control motor is driven with drive shaft, is set in the drive shaft
It sets there are two reversed, uniform pitch thread segment, the bipod of described scissor type telescopic mechanism one end is connected separately with and thread segment
Reversed nut correspondingly；Reverse thread makes the bipod synchronous backward of scissor type telescopic mechanism one end act, to make
Its crosspoint shaft is moved in a horizontal plane always, upper and lower both sides stress balance, it is ensured that service life.
The utility model compared with prior art the advantages of be：
Cross slide way is mounted on wall, and hanging ball mechanism is mobile, it is all sufficiently stable to stop, and the impact force that Ball for training is subject to is not
Hanging ball mechanism can be made to generate shaking, be easy to restore static, training interval is short, and cross slide way high strength, service life is long；It cuts
V shape telescoping mechanism makes multiple hanging ball mechanisms remain equidistant, for more people training simultaneously, not will produce shake between each other
Dynamic interference.
