Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present inventionFormula is described in further detail.
Embodiment
An embodiment of the present invention provides a kind of adjustable sport jumping stands, referring to Fig. 1, Fig. 2, adjustable bodyTo educate with jumping stand include base assembly 1, is connect with base assembly 1 adjustment component 2, the Buffer Unit being connect with adjustment component 23, the cross bar component 4 being connect with Buffer Unit 3；
Base assembly 1 includes first base 5, match the second base 6 of setting with first base 5；First base 5 and the second bottom6 structure function all sames of seat, are only described in detail by taking first base 5 as an example in the embodiment of the present invention；
First base 5 folds connection including pin bar 11, the cross support arm 12 being connect with pin bar 11, by axis pin and cross support arm 12Oblique fulcrum bar 14, roll wheel assembly 13 in 14 bottom of oblique fulcrum bar is set；It is provided with cross support arm locating slot 121 on cross support arm 12, oneEnd is provided with cross support arm positioning column 122；Oblique fulcrum bar positioning column 141 is provided on oblique fulcrum bar 14, one end is provided with oblique fulcrum bar positioningSlot 142；
Referring to Fig. 3, roll wheel assembly 13 includes the first telescopic rod 131 being arranged in 14 bottom of oblique fulcrum bar and the first telescopic rod 131The second telescopic rod 132 for being slidably connected, is set on spacer pin 133 spacer pin 133 being arranged in the second telescopic rod 132Compression spring 134, is connect with roller support 135 by shaft the roller support 135 being connect with 132 bottom of the second telescopic rodIdler wheel 136；
It includes the first adjustment device 7 being connect with first base 5, the second adjustment device being connect with second base 6 to adjust component 28；The first adjustment device 7 and 8 structure function all same of second adjustment device, only with the first adjustment device 7 in the embodiment of the present inventionFor be described in detail；
Referring to Fig. 4, the first adjustment device 7 includes the first riser 21 being connect with pin bar 11, by bolt 22 and the first riserSecond riser 23 of 21 connections, the support plate 25 being connect with the second riser 23；It is respectively provided on first riser 21 and the second riser 23There is mounting hole 20；Bolt 22 is set in mounting hole 20；By the position of adjusting bolt 22, the height of the first adjustment device 7 is adjustedDegree, is suitable for no high jump height；
Buffer Unit 3 includes the buffering ball 30 being connect with support plate 25, and buffering ball 30 is rubber system cryptomere sphere structure, including ballShape bottom 31, the spherical top 32 being connect with spherical bottom 31；30 lightness sensation in the upper and heaviness in the lower of buffering ball；
Referring to Fig. 5, cross bar component 4 includes cross bar 41, is arranged in the cross bar magnet 42 of 41 both sides of cross bar, connect with buffering ball 30Installation magnet 44 in 43 side of mounting plate is arranged in mounting plate 43；Cross bar magnet 42 matches setting with installation magnet 44；Pass throughCross bar magnet 42 can be flexibly connected with installation magnet 44, cross bar 41 with mounting plate 43；
When high jump practitioner's high jump, when practitioner encounters cross bar 41 but smaller touching active force, Buffer Unit 3 tilts therewith, practicesHabit person can cross the bar 41, but cross bar 41 and not fall off, and can be restored to elemental height again therewith；When practitioner encounters crossWhen bar 41 but larger touching power, Buffer Unit 3 tilts therewith, and cross bar 41 just can fall off from mounting plate 43, avoid driveThe danger integrally turned on one's side, safety are relatively high.
The advantageous effect that technical solution provided in an embodiment of the present invention is brought is：
Adjusting apparatus is set, carries out the height adjustment of cross bar, folding roll wheel assembly is set, movement when easy to use, ifBuffer Unit is set, the danger for driving and integrally turning on one's side is avoided, increases safety, greatly facilitate physical education.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit andWithin principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
