Add and make beginner frightened.
Hurdles rack is the support for support rail when hurdling, and the hurdles rack fixed transverse rod in existing design uses spiral shell mostly
Silk, dismantles pretty troublesome if fixed, but more allow people worries is：Because screw fixed transverse rod is very firm, once knock
Railing or ride railing will danger close, larger potential safety hazard be present in existing hurdles rack.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, providing track and field a kind of reasonable in design, safer with hurdling
Frame.
To reach above-mentioned purpose, the utility model employs following technical proposal：This track and field hurdles rack, including base,
Described base is provided with column, is provided with cross bar of hurdling between described column, support bar, institute are connected between described base
The madial wall for the column stated is provided with sliding groove, and the both ends of described cross bar of hurdling are provided with the magnetic being engaged with sliding groove and slided
Block, the interior magnetic location blocks provided with the rotation connection of some and column of described sliding groove, between the magnetic location block and column
Provided with the spring to magnetic location block with upward pretightning force, and when magnetic sliding shoe overcomes the pretightning force of spring by magnetic location
Block cross bar of being hurdled after pushing is automatically fallen off along sliding groove.
In above-mentioned track and field hurdles rack, described magnetic location block is longitudinally uniformly distributed along sliding groove, sliding groove
Mounting groove is inside provided with, described magnetic location block is rotatablely connected by rotary shaft and mounting groove inwall.
In above-mentioned track and field hurdles rack, described magnetic location block has the locating surface being obliquely installed and is horizontally disposed with
Abutment face, described locating surface and abutment face are crossed to form angle.
In above-mentioned track and field hurdles rack, described magnetic sliding shoe is provided with the inclined plane being engaged with locating surface,
And locating surface and inclined plane fit when cross bar of hurdling is placed on column.
In above-mentioned track and field hurdles rack, one end of described spring is connected with mounting groove inwall, spring it is another
End is connected with abutment face.
In above-mentioned track and field hurdles rack, the end of described magnetic sliding shoe is rotatably connected to movable pulley, when hurdling
Cross bar by movable pulley during the external force pushed along locating surface lower slider by magnetic location block be pressed into mounting groove then along
Sliding groove longitudinally glides.
Compared with prior art, this track and field is with the advantages of hurdles rack：It is not solid to hurdle between cross bar and column
Fixed connection, but rely on the pretightning force of spring to cause magnetic location block to be held in position face-up state, magnetic sliding shoe is entered
Row support, and when student rides and hurdles cross bar, cross bar stress of hurdling and slide automatically, so as to avoid student from falling down, more pacify
Entirely, solves the problems, such as beginner's fear.
Brief description of the drawings
Fig. 1 is overall structure diagram provided by the utility model；
Partial enlarged drawing when Fig. 2 is cross bar provided by the utility model of hurdling non-stress；
Fig. 3 be it is provided by the utility model hurdle cross bar stress when partial enlarged drawing.
In figure, base 1, column 2, cross bar 3 of hurdling, support bar 4, sliding groove 5, magnetic sliding shoe 6, magnetic location block 7, bullet
Spring 8, mounting groove 9, rotary shaft 10, locating surface 11, abutment face 12, inclined plane 13, movable pulley 14.
Embodiment
Following examples only exist in illustrative purpose, without being intended to limit the scope of the utility model.
Embodiment
As Figure 1-3, this track and field hurdles rack includes base 1, and base 1 is provided with column 2, be provided between column 2 across
Column cross bar 3, support bar 4 is connected between base 1, the madial wall of column 2 is provided with sliding groove 5, and the both ends for cross bar 3 of hurdling are provided with
The magnetic sliding shoe 6 being engaged with sliding groove 5, sliding groove 5 are interior provided with some magnetic location blocks 7 being rotatablely connected with column 2, institute
The spring 8 for being provided between magnetic location block 7 and column 2 and there is upward pretightning force to magnetic location block 7 is stated, and works as magnetic sliding shoe
6 overcome spring 8 pretightning force magnetic location block 7 is pushed after cross bar 3 of hurdling automatically fallen off along sliding groove 5, cross bar 3 of hurdling is adopted
It is made of light material so that the pretightning force of spring 8 can support cross bar 3 of hurdling when hurdling 3 non-stress of cross bar.Hurdle cross bar
It is not to be fixedly connected between 3 and column 2, but relies on the pretightning force of spring 8 to cause magnetic location block 7 to be held in position the court of face 11
On state, magnetic sliding shoe 6 is supported, and when student rides and hurdles cross bar 3, the stress of cross bar 3 of hurdling and slide automatically
Fall, it is safer so as to avoid student from falling down, solve the problems, such as beginner's fear.
