Abstract
The utility model discloses a kind of track and field hurdles rack, comprise base, railing and beam, described beam two ends are fixedly connected with two railings respectively, column on the lower end of two railings and base is hinged fixing, pin joint is positioned at the centre position of column, the column upper end of base is provided with magnet, described beam upper end is provided with rotary soft roll, the leg when training athlete is competed, foot, when internal malleolus collides the soft roll on beam, this soft roll forward direction can produce rotation, soft roll rolls progressively can cut down decomposition to impact force, in addition the effect of soft roll elastic buffer can be avoided or alleviate athletic injury.Two railings under external force simultaneously, throws off, dump forward with magnet, and beam only can produce less resistance to sportsman, sportsman can't be tripped, and reduces the possibility to athletes ' body injury.
Description
Technical field
The utility model relates to field of sports equipment, particularly a kind of track and field hurdles rack.
Background technology
Existing " Athletics competition rule 2008 " specifies: " hurdle race uses the top bar chain timbers material on hurdle frame or other appropriate materials to make.Top bar appearance and size: 1.18 ~ 1.20*0.07*0.01 ~ 0.025m.Top bar top edge should be round and smooth, and two ends should be fixed." at present when training and regulation game, generally adopt the top bar that entirety is made for wood materials, its hard top edge easily collides and injures athletic leg, foot, internal malleolus, this is the practical problem that puzzlement hurdle race project is properly settled so far.
Utility model content
The purpose of this utility model is to provide a kind of track and field hurdles rack, effectively can reduce the danger coefficient of hurdle campaign, is training or during the games, is avoiding hard beam collision to injure athletic leg, foot, internal malleolus.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of track and field hurdles rack, comprise base, railing and beam, described beam two ends are fixedly connected with two railings respectively, column on the lower end of two railings and base is hinged fixing, pin joint is positioned at the centre position of column, the column upper end of base is provided with magnet, and described beam upper end is provided with rotary soft roll.
The beneficial effects of the utility model are:
When training athlete is competed, leg, foot, internal malleolus collide the soft roll on beam, this soft roll forward direction can produce rotation, soft roll rolls progressively can cut down decomposition to impact force, and the effect of soft roll elastic buffer can be avoided or alleviate athletic injury in addition.Two railings under external force simultaneously, throws off, dump forward with magnet, and beam only can produce less resistance to sportsman, sportsman can't be tripped, and reduces the possibility to athletes ' body injury, uses when being particluarly suitable for training.

Detailed description of the invention
As shown in Fig. 1 to 2, a kind of track and field hurdles rack, comprise base 1, railing 2 and beam 3, described beam 3 two ends are fixedly connected with two railings 2 respectively, column on the lower end of two railings 2 and base 1 is hinged fixing, pin joint is positioned at the centre position of column, and the column upper end of base 1 is provided with magnet 5, and described beam upper end is provided with rotary soft roll 4.
As shown in Figure 5, described soft roll 4 comprises a rotatable axle and is coated on the glue-line 6 on axle.
Operation principle of the present utility model is as follows, during use, base 1 is placed on the specified location on athletic ground, railing 2 is perpendicular to the ground, railing 2 adopts material to be iron, under the magnetic force of magnet 5 attracts, to be kept upright state, when when training athlete is competed, leg, foot, internal malleolus collide the soft roll 4 on beam 3, this soft roll 4 forward direction can produce rotation, soft roll rolls progressively can cut down decomposition to impact force, and the effect of soft roll elastic buffer can be avoided or alleviate athletic injury in addition.Two railings 2 under external force simultaneously, throws off, dump forward with magnet 5.Owing to only needing less power namely can cause toppling over of railing 2, that is, beam 3 only can produce less resistance to sportsman, sportsman can't be tripped, and reduces the possibility to athletes ' body injury.
Be only the specific embodiment of this patent above, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle, the distortion made should be considered as belonging to the utility model protection domain.
