Abstract
The invention relates to a magnetic auto-return hurdle. According to the technical scheme, the magnetic auto-return hurdle mainly comprises bases, uprights, and cross bars. A rotating plate is disposed at the upper end of each upright and movably connected with one end of the corresponding cross bar. The corresponding parts of the uprights and rotating plates are provided with magnets of different polarities, and the corresponding parts of the rotating plates and cross bars are also provided with magnets of different polarities. According to the principle that the magnets of different polarities attract and repel, the hurdle can automatically return. The magnetic auto-return hurdle has the advantages of good auto-return effect, simple structure and attractiveness.
Description
Technical field
The present invention relates to sports equipment, especially a kind of magnetic-type auto-reset hurdles rack.
Background technology
In prior art, the hurdles rack with auto-reset function as notification number be CN1827199A(door-opening type safety elastic hurdle stand) by base, metal tube, perpendicular spring, cross spring, L-type metal tube, T-shaped metal tube, foam flexible pipe and magnetic post, formed, complicated structure, simultaneously more spring is because using area mostly is outdoor, and exposing to the sun and rain also gets rusty easily causes flexibility decrease impact to be used.Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of magnetic-type auto-reset hurdles rack that is particularly suitable for training, teaching.
The technical solution adopted in the present invention is, hurdles rack is by base, column, cross bar critical piece forms, in column upper end, be provided with rotor plate, rotor plate is eccentric, component of rotation plate long end and rotor plate short end, there is through hole at rotor plate center, being fixed on the middle rotor plate fixed screw of column has through hole and top cover to be fixed on column upper end through rotor plate center, rotor plate long end is flexibly connected with cross bar one end, utilize different generation of magnet polarity to inhale mutually the principle of repelling each other, at column and rotor plate, the corresponding place of rotor plate and cross bar is respectively arranged with the magnet of opposed polarity, magnet polarity group can one group, more can two or more groups, for the purpose of identification, white end is that N utmost point black end is the S utmost point for convenience, there is the breach of 90 degree in the place of column installation rotor plate, so that rotor plate long end is stretched out within the scope of breach and is rotated from indentation, there, rotor plate long end is axially flexibly connected with fixed screw or pin with cross bar, when rotor plate long end and cross bar are vertical with runway, magnet on rotor plate is that heteropole is inhaled mutually with the magnet on column, between rotor plate long end and cross bar, be also provided with the magnet of opposed polarity, magnetic force can make cross bar in level, this is also the normal condition of hurdles rack.When athletic health touching cross bar only has downward power, the suction that cross bar overcomes magnet be take and is flexibly connected point as the downward other end in one end, the center of circle to top offset, because cross bar displacement is arranged on magnet on cross bar and the magnet in rotor plate long end, by heteropole, gradually becomes homopolarity and can produce repulsive force and cause cross bar, because departing from level counter the pushing away that make progress, impelling cross bar horizontal reset; When athletic health touching cross bar only has power upwards, the suction of magnetic force and repulsive force reset principle are the same; When athletic health touching cross bar only has power forward, cross bar drives rotor plate to overcome with the suction of column magnet and does to horizontally rotate, the displacement of rotor plate makes to be arranged on magnet on rotor plate and the magnet on column and by heteropole, gradually becomes homopolarity and produce repulsive force and cause rotor plate to depart from entopic counter pushing away, and impels rotor plate and runway vertical reset; When producing forward when athletes ' body touching cross bar or making progress downward making a concerted effort, the reseting procedure of cross bar and rotor plate just carries out as previously discussed simultaneously.
Be described in further detail below, column bottom is fixedly connected with base, column bottom and top can lift adjustment to adapt to different needs; The breach on column inwall and column top is provided with the vertical magnet of opposed polarity, uniform 90 degree; Cross bar is provided with four blocks of magnet of opposed polarity around connection hole; Porose being convenient to of lid periphery is screwed and is connected with column, and it is rear with fastening nuts that top cap central bore facilitates rotor plate fixed screw to pass; Rotor plate two ends are respectively arranged with magnet, the hole that rotor plate is connected with cross bar fixed screw is provided with two groups of totally four blocks of magnet around, wherein a penetrating type is inlayed setting, remaining one side arranges, rotor plate short end is a vertical bar magnet, and while being designed to cross bar with ground level, the magnet heteropole at rotor plate fixed screw two ends is inhaled mutually, continues to be on the one hand subject to the attraction of heteropole in the time of displacement, is subject on the other hand the repulsion of homopolarity; The magnet that rotor plate two ends arrange when rotor plate is vertical with runway and the magnet heteropole of column breach and stud wall setting are inhaled maintenance poised state mutually, the displacement reset that repels each other; While there is cross bar downwards with to anterior resultant force, above-mentioned homing action carries out simultaneously simultaneously.This technology is can be separately a set of also can be used in conjunction with by two covers, when be independent when a set of because cross bar is longer, on cross bar free end and corresponding column, be provided with heteropole magnet so that cross bar is more stable; When being embodied as Liang Tao mechanism and being used in conjunction with, cross bar size short half, two cover mechanism action principles are identical.
The invention has the beneficial effects as follows automatically reset effective, simple and beautiful structure.
Below in conjunction with drawings and Examples, the invention will be further described in accompanying drawing explanation.
