Degree, while hurdling after the completion of competing and can be only placed at not foldable, occupied space on one side.
Utility model content:
The purpose of this utility model, which needs the standing that will be toppled over just before being the existing hurdle race of solution, can be carried out, occupy sky
Between the problem of, one kind is provided and prevents from hurdling and is toppled over, folding track and field events are hurdled device with folding overturning-preventing.
Above-mentioned purpose is realized by following technical scheme:
A kind of track and field events are hurdled device with folding overturning-preventing, and composition includes: two foundation, the foundation top with
Tightener is fixedly connected, and the side plate of the tightener side and the shaft of cross bar one end are bolted, the tightening
Device includes the sleeve covered on column, and the sleeve inner is connect with the column by bearing, the column lower part
It is rotatably connected to fixed column, the strip-shaped hole that the end of the fixed column passes through the foundation side passes through with the foundation
It is bolted, the foundation bottom is fixedly connected with L shaped plate, and the L shaped plate passes through the strip-shaped hole on rear side of the foundation
It is connect with the foundation by spring.
The track and field events are hurdled device with folding overturning-preventing, and the cross bar other end is provided with stepped groove, described
Stepped groove in be placed with magnetite and iron plate, the ladder groove location face of cross bar described in two, the rank described in one of them respectively
Iron plate in terraced slot corresponds to the magnetite in the stepped groove described in another.
The track and field events are hurdled device with folding overturning-preventing, and the bearing is respectively arranged with wind spring in two sides up and down,
The wind spring covers on the column, and the inside of the wind spring is fixedly connected with the column, the wind spring
It is external to be fixedly connected with the sleeve inner.
The utility model has the advantages that
1. the working principle of the utility model are as follows: before carrying out hurdle race, unscrew the bolt in fixed column, rotation is solid
Fixed column, so that the angle change between sleeve and ground, adjusting is in 45-60 degree angle between sleeve and ground, screwing bolts, into
When row track and field hurdle race, the foot of sportsman encounters on cross bar, and cross bar can forward downward rotation under the action of sportsman foot
Turn, wind spring is shunk, and two cross bars separate, and sportsman continues to run forward, when cross bar is detached from the effect of foot in the effect of wind spring
Lower reverse rotation, when so that two cross bars being rotated on straight line, the magnetite on a cross bar is sucked on another cross bar
Iron plate stops rotating, and after the completion of match, unscrews the bolt in cross bar shaft, so that cross bar is in a vertical state, then revolves
Bolt in loose fixed column, so that sleeve moves down, final sleeve moves to strip-shaped hole lower part.
Two cross bars are arranged in the utility model, prevent from hurdling and topple over, while two cross bars can rotate, and rotate latter two cross
It is no any connection between bar, preventing from hurdling trips sportsman, and hurdling all to dump forward prevents from stumbling sportsman
?.
The utility model be arranged tightener, the cross bar font of rotation can be revert to home position, do not need personnel into
Row is propped up.It hurdles after the completion of match simultaneously foldable, is not take up space.
The utility model when not in use, can all slide into tightener and cross bar in foundation, save space, while two
The apparatus structure of hurdling being grouped as is identical, has replaceability, reduces the cost of replacement.

Specific embodiment:
Embodiment 1:
A kind of track and field events are hurdled device with folding overturning-preventing, and composition includes: two foundation 9, foundation lower part and pedestal
It is fixedly connected, pedestal is disc format, can play firm effect, and the foundation top is fixedly connected with tightener 5, institute
The side plate 2 for the tightener side stated and the shaft of 1 one end of cross bar are bolted, and can when not in use erect cross bar,
In a vertical position, the tightener includes the sleeve 4 covered on column 3, and the sleeve inner and the column are logical
Bearing connection is crossed, the bearing is respectively arranged with wind spring 6 in two sides up and down, and the wind spring covers on the column, described
The inside of wind spring be fixedly connected with the column, the outside of the wind spring is fixedly connected with the sleeve inner, institute
The column lower rotational stated is connected with fixed column 7, the end of the fixed column pass through the strip-shaped hole 8 of the foundation side with
