When playing table tennis,, come placement near or far away because the dealing speed of ball is very fast, left or right, or rotation or do not change, judge in order to make accurately, how obtain the information of ball by eyes, eyeball is in the motion at a high speed all the time, and feeds back fast with brain and to get in touch.Unique sports items of this adjusting to eyes and eyesight, over-burden to school work, and the long-time closely primary and secondary students of reading can improve the function of eyes ciliary muscle effectively, and vision protection, pre-myopia prevention are all had positive role.
In all ball game projects, the speed of table tennis is than faster.Because spheroid is small and light, change between attack and defend is rapid, it require the sportsman must be in the shortest time to transferring sense organs such as vision, the sense of hearing, the ball that is changing made judges accurately and react.Thisly need the diligent characteristics that beat one's brains, can temper the elderly's respond well, temper the sensitivity of human brain, play table tennis and to prevent the elderly brain dementia, delay elderly brain artery sclerosis, keep good thinking memory surrounding.
The muscle power that consumes of playing table tennis is very big, can improve a poor appetite.In addition, health ceaselessly moves back and forth, and also can promote the wriggling of stomach.
Table tennis not only requires eye to want fast, and hand is more wanted disease, and step also needs rapid moving to make cooperation, long-term exercise can make the joint of upper and lower extremities more flexible, and the muscle of the small of the back is also more healthy and stronger, and whole people's physical function is given full play to, harmony and flexibility all are improved, and be more dynamic.
Use psychometric testing that the result of study of the outstanding children paddler of China part provinces and cities psychological traits is shown according to the psychology personage: it is higher that they generally show as intellectual level, operational capacity is better than pass student, be emotionally stable, self-confidence, power self-assured for having something or somebody to rely on, independence, resourceful property are all stronger, mental factor and personality factors development are coordinated, in daily life, usually seem alert and resourceful remarkable, flexible movements, coordination of these people.
Therefore, table tennis is a physical fitness activity that should be widely promoted, utensil that it need be used and place are also fairly simple, table tennis and table tennis bat can be carried, which is gone to practices and to arrive that, unique needs be ping-pong table, yet regular ping-pong table is not many really, most people, especially children, student on the basis of the existing conditions no matter how simple and crude, are practised once piecing together into simple and easy table tennis table by individual big desk, at this moment, many problems are table tennis nets, usually are that width is inapplicable, and are perhaps long, perhaps short, and table tennis is played in influence.
(3) summary of the invention
The purpose of this invention is to provide a kind of a kind of structure that can change the table tennis net width, make common table tennis net can adapt to more occasions, wide or narrow desk uses.
Purpose of the present invention is solved by following technical scheme:
A kind of table tennis post, comprise vertical net bar and the spiral gripper frame that is the Contraband word, the upper side edge of Contraband word gripper frame is long fixed head, the lower side top that the threaded rod of spiral handle passes Contraband word gripper frame is a grip block, it is characterized in that: a moving sheet is fixed in the bottom of described net bar, the net bar is moved and is fixed on the long fixed head by mobile governor motion.
Described mobile governor motion is: the cross section of described long fixed head is opening upwards, and the recess shape that is bent inwardly into of dual-side, the moving sheet of described net bar bottom embeds in the recess groove of long fixed head, one piece of circular hole piece is fixed at the two ends of long fixed head respectively, insert a long bolt in the circular hole of two circular hole pieces, the middle part of long bolt screws in the screwed hole of net bar, the outside exposed junction configuration rotary handle of long bolt.
The length of described long fixed head is 20 to 30 centimeters.
Adopt the technical program, the spiral gripper frame of Contraband word is clamped in the edge of desk, turning spiral handle makes grip block clamp the edge of desk, regulating the mobile governor motion of adjustment this moment moves the net bar on long fixed head, net on the net bar can be tightened, till can blocking, fix the position of net bar on long fixed head this moment.
Provide following mode as for mobile governor motion.
One piece of circular hole piece is fixed at the two ends of long fixed head respectively, insert a long bolt in the circular hole of two circular hole pieces, the middle part of long bolt screws in the screwed hole of net bar, the outside exposed junction configuration rotary handle of long bolt, rotate rotary handle, make the net bar on long bolt, to move outward inward---because the moving sheet of net bar bottom embeds in the recess groove of long fixed head, place restrictions on net bar and moving sheet thereof and can only in the recess groove, move and can not rotate.Rotate rotary handle, adjust the net bar time the correct position, also fixed the position of net bar by the self-locking action of screw rod simultaneously.
Beneficial effect of the present invention: the technical program adopts simple means just can regulate the position of the net bar of fixing table tennis net at desk two side directions, so that adapt to fixing and tightening of different in width desk table tennis net, be convenient to carry out table tennis activity of a mass character, obtain dramatic benefit benefit as described in the background art in occasion flexibly.
