Background technology
Track and field or track and field sports are the full name of field events, track and combined race.The classification of modern track and field movement is different,
The main all-round athletic event formed including footrace, race, jump, throwing and race, jump, jump, some projects of throwing, amounts to more than 40
.
Hurdle race campaign originates from Britain.When 17th to 18 century, some ground pastoral industries of Britain are quite flourishing, and herdsman pass through
Corral need to be often crossed over, the livestock to escape is pursued.In red-letter day, some like lively young herdsman also usually holds to jump over sheepfold
Game, they move fence on level land to, if several height and the similar obstacle of sheepfold, see that who can run up front, this is just
It is the blank of match of hurdling.Hurdle race is in certain distance, across the column frame of defined height and quantity, technical stronger short
Race project.International tournament man is 110 meters of high hurdle, and column is 106 centimetres high, column number 10；Woman is M 100 low hurdles, and column is 84 lis high
Rice, column number 10.18 end of the centurys, activity of hurdling formally become sports item.
The barrier of early stage is general fence, occurs the wooden column frame for being embedded in ground later, is changed to rubber saw again still later
The holder of timber, but this barrier during crossing over is easy to that accident occurs, while being also unfavorable for hurdle race technology
Raising；For this purpose, there are moveable " ⊥ " shape column frame 20th century, the development of hurdling technique has been pushed.Nineteen thirty-five occurs again
" L " shape column frame, breast board will tip forwards by 4 kilograms of shock strength.However present track and field hurdles rack uses mostly
The leg and foot for injuring sportsman are easily collided in generally railing made of wood materials, its hard top edge, and there are certain
Security risk.
Utility model content
The purpose of this utility model is that there is security risk for existing track and field hurdles rack, one is provided
Kind track and field safe hurdle bar.
To achieve the goals above, the technical solution that the application uses for：Track and field safe hurdle bar, including pedestal, column
Bar and beam；
The both ends of pedestal have been respectively fixedly connected with strut, and railing, the top and column of strut are correspondingly arranged on above strut
The bottom of bar is respectively provided with groove, and (the first back-moving spring, the connecting portion of strut outer wall and railing outer wall are fixedly connected in groove
It is fixedly connected with telescopic；
Beam includes identical first beam of length and the second beam, the right side of the left end of the first beam and the second beam
Side end is respectively with the upper articulation of corresponding railing, and right side is both provided with before the front, left side of the first beam and the second beam
The leading flank of first fastening bolt, left and right railing is both provided with the second fastening bolt, the second fastening bolt and the first fastening bolt
Positioned at identical height, the first fastening bolt be fixedly connected with second back-moving spring in corresponding second fastening bolt, first is horizontal
The right-hand end of wood and the left end of the second beam are provided with the magnet that can be mutually attracted, on the first beam and the second beam
It is both provided with soft column top.
The utility model is also characterized by：
Wherein, the length of (the first back-moving spring be more than the groove of strut and railing length and.
Wherein, telescopic uses rubber material, and the length of telescopic is more than the length of exposed (the first back-moving spring
Degree.
Wherein, soft column top is provided in round using rubber material and top edge.
Compared with prior art, the utility model has the beneficial effects that：The utility model is horizontal by the first beam and second
Magnet setting and the first beam, the second beam and railing between wood are hinged, can make hurdler touch across
Beam is opened and rotated when column frame, avoids injuring caused by rigid collision of the hurdles rack to sportsman, first resets bullet at this time
Spring can make the first beam and the second beam set back, and reduce manual operation, and second back-moving spring can reduce sportsman and hit
To the bounce of hurdles rack, telescopic can make railing be restored to vertical state, effectively reduce sportsman during hurdling
The possibility wounded, safety coefficient are high.

Specific implementation mode
With reference to the attached drawing in the utility model embodiment, to the specific implementation mode of the utility model into traveling
One step describes.
As depicted in figs. 1 and 2, track and field safe hurdle bar, including pedestal 1, railing 2 and beam, pedestal 1 are used to hurdle
Frame provides support, and railing 2 is used for connect base 1 and beam, and beam, that is, sportsman process of hurdling needs the obstacle crossed over；
The both ends of 1 top of pedestal have been respectively fixedly connected with strut 3, and the top of strut 3 is correspondingly arranged on railing 2, strut 3
Top and the bottom of railing 2 be respectively provided with groove, (the first back-moving spring 4,3 outer wall of strut and railing 2 are fixedly connected in groove
The connecting portion of outer wall is fixedly connected with telescopic 5, and strut 3 is used to provide support, (the first back-moving spring for (the first back-moving spring 4
4 are fixedly connected with the groove at 3 top of strut and 2 bottom of railing, and the length of (the first back-moving spring 4 is more than the length of two grooves
And have partial spring exposed at the connecting portion of strut 3 and railing 2, telescopic 5 is set to the connection of strut 3 and railing 2
Position, and be fixedly connected with strut 3 and railing 2, telescopic 5 coats exposed (the first back-moving spring 4 completely, and telescopic 5
With certain telescopicing performance, when sportsman strikes hurdles rack, railing 2 shakes, and (the first back-moving spring 4 is shaken
It moves and railing 2 is restored to original position, telescopic 5 can assist (the first back-moving spring 4 that railing 2 is restored to original position, can both subtract
Small sportsman bumps against the bounce of hurdles rack generation, and can restore automatically, saves manpower；
Beam includes identical first beam, 6 and second beam 7 of length, the left end of the first beam 6 and the second beam 7
Right-hand end respectively with the upper articulation of corresponding railing 2, it is hinged to surround railing for meeting the first beam 6 and the second beam 7
2 are rotated, and right side is both provided with the first fastening bolt 8 before the front, left side of the first beam 6 and the second beam 7, left and right
The leading flank of railing 2 is both provided with the second fastening bolt 9, and the second fastening bolt 9 is located at identical height with the first fastening bolt 8,
First fastening bolt 8 with second back-moving spring 10, the right side of the first beam 6 are fixedly connected in corresponding second fastening bolt 9
The left end of end and the second beam 7 is provided with the magnet 11 that can be mutually attracted；On first beam 6 and the second beam 7
It is provided with soft column top 12, the first beam 6 and the second beam 7 that second back-moving spring 10 is used to rotate are restored to original position, can
The magnet 11 being mutually attracted avoids the first beam 6 for being attracted when the first beam 6 and the second beam 7 are restored to original position
It shakes with the second beam 7, when sportsman strikes beam, impact force makes to be attracted between the first beam 6 and the second beam 7
Magnet 11 separate, the first beam 6 and the second beam 7 are rotated around railing 2, reduction hurdles rack the rigidity of sportsman is hit
Evil is wounded, then the first beam 6 and the second beam 7 are restored to original position by second back-moving spring 10, and magnet 11 is mutually attracted, across
