Specific embodiment

The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this Content disclosed by specification understands other advantages and effect of the utility model easily.

As shown in Figures 2 and 3, the utility model provides a kind of hurdles rack, the pedestal extended along the longitudinal direction including two 1, connecting rod 2, two piece columns for vertically extending 3 affixed with the front end of two pedestals 1 and upper with two root posts 3 Affixed plate 4 of hurdling is held, the lower end of two root posts 3 is connected with the front end of two pedestals 1 respectively, and two pedestals 1 are in left-right direction It is spaced apart, the front end of pedestal 1 and reset guide part 5 are affixed, and reset guide part 5 has arc surface 51.In the utility model When in use, when the foot of sportsman touches plate 4 of hurdling, and applies forward power to plate 4 of hurdling, plate 4 of hurdling will for hurdles rack It drives entire hurdles rack to tumble forward along the arc surface 51 of reset guide part 5, causes excessive blocking to make to avoid to sportsman With, and when hurdles rack tumble to a certain degree after, under the gravity of two pedestals 1, entire hurdles rack will be along reset guide The arc surface 51 of part 5 is turned over, until two pedestals 1 return to ground again, and entire hurdles rack is reset to initial shape again State, to realize the function of this hurdles rack energy self-resetting.Meanwhile hurdles rack overall structure is simple in the utility model, processes Cost is relatively low.

As shown in Figures 2 and 3, in the present embodiment pedestal 1 rectangular in cross-section, and the material of pedestal 1 be steel.The present embodiment Middle pedestal 1 can be process by rectangular steel tube.Meanwhile the front end of pedestal 1 is equipped with clump weight 6 in the present embodiment, and resets and lead The front and rear sides of column 3 are located to part 5 and clump weight 6.When hurdles rack is tumbled forward along the arc surface 51 of reset guide part 5 When, the gravity of the gravity of clump weight 6 and pedestal 1 by drive jointly entire hurdles rack along reset guide part 5 arc surface 51 backward It tumbles, until two pedestals 1 return to ground again, and entire hurdles rack is reset to original state again.The present embodiment by It installs clump weight 6 on pedestal 1 additional and increases effectively the torque that can drive hurdles rack reverse flip when hurdles rack is tumbled forward, from And guarantee that hurdles rack can smoothly reset in the utility model.And the effect based on the clump weight 6, the length of pedestal 1 in the present embodiment Degree also can be set relatively short, and the overall volume of this hurdles rack is smaller.

Meanwhile the material for plate 4 of hurdling in the present embodiment is rubber, with the plate 4 that guarantees originally to hurdle with good flexibility.Work as fortune The foot of mobilization touches when hurdling plate 4, which will not generate biggish impact force to the foot of sportsman, with Avoid the foot of sportsman injured.Hurdle in another embodiment plate 4 material be silica gel.

As shown in Figures 2 and 3, the lower end of the present embodiment central post 3 is connected by spring 7 with the front end of pedestal 1.Work as fortune It mobilizes when applying forward power to plate 4 of hurdling, plate 4 of hurdling will drive column 3 to tumble forward, and column 3 will be given by the spring 7 Pedestal 1 applies the power tumbled forward, and effective part that absorbs is applied to the power that pedestal 1 is tumbled forward by spring 7 at this time, the bottom of to avoid Seat 1 is quickly tumbled forward, and the amplitude that pedestal 1 is tumbled forward can be effectively reduced, and the power that spring 7 absorbs is converted into itself Deformation power, which will drive column 3 and plate 4 of hurdling to turn over, to guarantee that hurdles rack can quickly, smoothly reset.

As shown in Figures 2 and 3, the present embodiment central post 3 includes upper pillar stand 31 and lower pillar stand 32, and upper pillar stand 31 passes through screw Affixed with lower pillar stand 32, upper pillar stand 31 is equipped with multiple upper screwed holes 311 being spaced apart along the vertical direction, sets on lower pillar stand 32 There are multiple lower threaded holes 321 being spaced apart along the vertical direction, screw is threadedly coupled with upper screwed hole 311 and lower threaded hole 321. When in use, it is matched by adjusting screw from different lower threaded holes 321 and upper screwed hole 311, to realize that column 3 is entire high The adjustment of degree, and then realize the adjustment to 4 height of plate of hurdling, and meet corresponding training or match demand.On in the present embodiment In a tubular form, as shown in Figures 2 and 3, the lower end of upper pillar stand 31 is inserted in the upper end of lower pillar stand 32 for column 31 and lower pillar stand 32.And Upper pillar stand 31 and lower pillar stand 32 are specific cylindrical in the present embodiment.In addition, two neighboring upper screwed hole 311 in the present embodiment Spacing it is equal with the spacing of two neighboring lower threaded hole 321.The upper screwed hole 311 of every upper pillar stand 31 has 4 in the present embodiment A, the lower threaded hole 321 of every lower pillar stand 32 has 3.

As shown in figure 3, being equipped with multiple optoelectronic switches 8 on the present embodiment central post 3, whole optoelectronic switches 8 are vertically square To being spaced apart.When sportsman hurdles, when the detection laser that corresponding optoelectronic switch 8 issues is blocked, illustrate sportsman From from this across.Spanning height when effectively detection sportsman hurdles using optoelectronic switch 8 in the present embodiment.Meanwhile part light Electric switch 8 is located at the top of plate 4 of hurdling, and another part optoelectronic switch 8 is located at the lower section for plate 4 of hurdling, with guarantee when sportsman across When more excessively high or too low, the height of actually hurdling that corresponding optoelectronic switch 8 detects sportsman is had, and then convenient for movement The movement of hurdling of member's timely correction oneself in subsequent training.
