One end of each hurdle board (2) is fixed with two transverse rods connected with the rotating axle (4) and fixed with the vertical rod (3) and the base frame (1) by mechanical mode. The connecting point of each hurdle board (2) and the vertical rod (4) can freely rotate in the horizontal flat surface by the rotating axle (3). The contacting ends of the two hurdle boards (2) are respectively provided with one magnetic iron (6) whose polarity is opposite or one end is provided with one magnetic iron and the other end is provided with an iron sheet.
Description
Technical field
The utility model relates to sports movement apparatus.Be specifically related to a kind of door-opening type safety frame of hurdling.
Background technology
Hurdling is sports movement apparatus commonly used in the track and field events; but track and field events at present are employed usually hurdles and is mostly fixed structure; its underframe and support meet at right angles fixing; this shortcoming of hurdling is exactly; existing breast board can adopt the harder material of some quality usually; when the sportsman hurdles action; shank is run into breast board easily; cause the sportsman to fall down easily; and when the facade of hurdling falls down; its base fixed mount has sticked up with identical angle simultaneously, and the scratch athletes ' body causes certain injury easily.Also be the physical education project of many schools hurdling in addition, meeting be colluded down because of being afraid of to be hurdled and be produced timid psychology for the beginner, dare not hurdle, and causes danger easily all the better.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of door-opening type safely and effectively frame of hurdling on the basis of the existing frame of hurdling.
The utility model is achieved in that it is made up of two groups of framves of hurdling that separately can be independently rotate around stiff end in horizontal plane, thereby avoids colluding the generation of accident such as the wrestling of falling the breast board.
The frame of hurdling of the present utility model comprises underframe, breast board, rotating shaft, montant, cross bar, magnet.End at breast board is fixed with 2 cross bars, and 2 cross bars link to each other with rotating shaft simultaneously, and fix with montant and underframe mechanically.The tie point of breast board and montant can carry out freely rotating in horizontal plane by rotating shaft.
Of the present utility modelly can be made up of by the free hurdle frame that rotates at horizontal plane 2 independences, at the contravention that joins of two breast boards a magnet is housed respectively, magnet polarity is opposite, or an end adorns a magnet, and the other end is adorned an iron plate.Effect by magnet is combined closely two breast boards, and when the sportsman hurdles when colluding breast board, breast board will separate rapidly, avoid damaging.
The utility model is simple in structure, easy for installation, can reequip on the existing apparatus of hurdling, and can effectively protect athletic safety, has good value for applications.
Below, describe details and working condition in conjunction with the accompanying drawings and embodiments in detail according to the concrete device that the utility model proposes.
Description of drawings
Structural representation under Fig. 1 the utility model stand-by state
Structural representation under Fig. 2 the utility model open mode
The specific embodiment
As shown in drawings, 1 is that underframe, 2 is that breast board, 3 is that rotating shaft, 4 is that montant, 5 is that cross bar, 6 is magnet.
Underframe (1), breast board (2), rotating shaft (3), montant (4), cross bar (5), magnet (6) are formed 2 independences can the free hurdle frame that rotates at horizontal plane, end at breast board (2) is fixed with 2 cross bars (5), 2 cross bars (5) link to each other with rotating shaft (4) simultaneously, and fixing with montant (3) and underframe (1) mechanically.The tie point of breast board (2) and montant (4) can carry out freely rotating in horizontal plane by rotating shaft (3), at the contravention that joins of two breast boards (2) magnet (6) is housed respectively, and magnet (6) polarity is opposite.
