Description

Center punch for throwing of American football

Technical field

The invention relates to a kind of delivery location supplemental training device for the training team member, belongs to physical education training device field.

Background technology

It is after no play that rugby is striven the limit ball, adopts ball is knocked down the mode that is listed as between the sportsmen two, comes rapidly, restarts safely.It is one of rugby four Large Groups technology that rugby is striven limit playing skill art, is to set up a play and effectively obtain the important means of score.The accuracy of delivering is that this technology cooperates key, also is the prerequisite key element of the core of technology and the success or failure that set up a play.The at present international and domestic simulative training platform that there is no this technology of exploitation, so that the training of this technology can only rely on the exercise that cooperatively interacts of manpower, there is very large defective in a series of requirements of quality, efficient, intensity and the combination cooperation etc. of exercise, cause this technology in play often make a fault and technology not stable in performance, the intention of strategy, the tactics of match can't be achieved by the target of anticipation.The development of center punch for throwing of American football tool can solve the problem of above-mentioned existence, for the stable performance of technology provides safety and ensured that also the expansion performance for this technology provides perfect training tool.

Summary of the invention

In order to solve the problem of above-mentioned existence, the invention provides a kind of can substituting to lift team member, outplayer and be the deliver center punch for throwing of American football of training of delivery team member.

The purpose of the invention is achieved through the following technical solutions: center punch for throwing of American football, it is characterized in that: by base, walking mechanism, column, gear elevating mechanism and whirling arm mechanism consist of, described column is made of four joint columns, wherein the first column is positioned at the bottom, and be connected by flange with base, the 4th column is positioned at the top, be provided with whirling arm mechanism thereon, described whirling arm mechanism structure is: installation shaft bearing on the 4th column, rotating shaft is set on the bearing block by bearing, at rotating shaft rotating disc is installed, be provided with cover plate at bearing block, end at cover plate is connected with limiting plate, limiting plate is provided with extension spring, extension spring is connected with an end of rotating disc by hanging the spring bolt, the other end at rotating disc is provided with simulation arm socket, simulation arm socket is connected with the simulation arm, be provided with chute and elevating mechanism at the first column, described elevating mechanism structure is: at the first column support plate is installed, be provided with bearing block at support plate, couple axle and bearing are housed in it, at couple axle gear is installed, gear is meshed with tooth bar on the second column, tooth bar slides in the chute of the first column, handwheel is installed in the couple axle end, the other end at couple axle is installed ratchet, ratchet and limited block, be provided with reinforcing ring at the first column, the second column, the termination of the 3rd column is provided with lock sleeve, and described walking mechanism comprises road wheel and the walking handle that is installed on the base.

The beneficial effect of the invention: use this center punch for throwing of American football, can strengthen targetedly and improve the training to delivery team member's throwing technique ability.Exercise can 2 people or the exercise of many people subtend, also can 1 many balls of people specific exercises.Can remove the consumption and the fatigue of lifting the team member of muscle power in deliver teaching and the training, prevent that contingency from occuring.Improve teaching and the training quality of delivering, promote the raising of level of technique.Can be according to the use object in the field research training, adjust the exercise of accurately delivering of datum target height.Can be in all directions in conjunction with carrying out single exercise or modeled fit is practised with reference to the hypothesis enemy in the place, place.

The specific embodiment

Center punch for throwing of American football is made of base 8, walking mechanism, column, gear elevating mechanism and whirling arm mechanism, and walking mechanism comprises road wheel 9 and the walking handle 10 that is installed on the base 8.Column is made of four pipe joint shape columns, the first column 1, the second column 2, the 3rd column 3, the 4th column 4 is installed from the bottom to top successively, the first column 1 is positioned at the bottom, and be connected by flange 11 with base 8, be provided with chute 5 and elevating mechanism I at the first column 1, be provided with reinforcing ring 32 at the first column 1,33, elevating mechanism I structure is: be positioned at reinforcing ring 32 upper parts at the first column 1 support plate 12 is installed, be provided with bearing block 13 at support plate 12, couple axle 14 is fixed on the bearing block 13, at couple axle 14 gear 16 is installed, gear 16 is meshed with tooth bar 15 on the second column 2, tooth bar 15 is installed handwheel 17 in the chute 5 interior slips of the first column in couple axle 14 ends, at the other end of couple axle 14 ratchet 18 is installed, ratchet 19 and limited block 20.Be provided with between the second column 2, the 3rd column 3 between lock sleeve 6, the three columns 3 and the 4th column 4 and be provided with lock sleeve 7.Be provided with the whirling arm mechanism II at the 4th column, whirling arm mechanism II structure is: installation shaft bearing 21 on the 4th column 4, rotating shaft 22 is contained on the bearing block 21 by bearing 23, at rotating shaft 22 rotating disc 24 is installed, be provided with cover plate 25 at bearing block 21, be connected with limiting plate 26 at an end of cover plate 25, limiting plate 26 is provided with extension spring 27, extension spring 27 is connected with an end of rotating disc 24 by hanging spring bolt 28, is provided with at the other end of rotating disc 24 and simulates arm socket 29.Simulation arm 30 is inserted in the simulation arm socket 29.

When off working state, the 4th column 4, the

3rd column

3,2 contractings of the second column are extreme lower position in the sleeve of the first column 1.

During preparation, the 4th column 4 is at first pulled up in the sleeve of the 3rd column 3, and with lock sleeve 7 locking positionings; The 3rd column 3 is extracted in the sleeve of the second column 2, when being adjusted to the 4th column 4 to the extreme higher position, the recycling elevating mechanism rises column 2 and

column

3,4 raises together, makes whirling arm mechanism reach the highest again.Owing to be provided with tooth bar 15 in the second column 2, the gear 16 in the elevating mechanism and tooth bar 15 engagements shake handwheel 17 and make tooth bar 15 drive the second column 2 free liftings.The ratchet 19 control gear strokes of the ratchet mechanism by handwheel 17 other ends stop at an arbitrary position.

After adjusting height, center punch is placed on assigned address, the delivery hand begins training, mark 31 on the simulation arm 30 is the common hand shape of human body, when the rugby of throwing hits mark 31 on the simulation arm 30, after simulation arm 30 is stressed, under the drive of whirling arm mechanism II, rotate, realize that by the extension spring 27 and the limiting plate 26 that arrange in the whirling arm mechanism II simulation arm 30 automatically resets, and eliminates swinging.

Behind the end-of-job, mention walking handle 10, the pulling of 30 °～45° angle of center punch inclination just can be walked arbitrarily.

This locator can substitute two and lift team member and the skyborne outplayer of quilt picking-up, and different according to the Human Height of men and women adult group, teenager group and juvenile group and brachium, the characteristics that the traffic altitude scope is different, the column height can carry out the setting of many groups, to satisfy concrete specially position team member's demand height of actual team.Topple over for not making center punch be hit rear generation, the simulation arm has and is hit rear rotation self-return function.The delivery team member can hit according to the real space of this team on schedule, determines aiming delivery exercise, to improve the accuracy rate of batting.
