The jumping stand using in existing high jump is comprised of left socle, right support and height crossbeam, by left socle and right support, the number of altitude being set, height crossbeam can be placed in accurately on height and position, to entrant's jump height is demarcated.There is certain drawback in existing jumping stand, for example, some jumping stands, height crossbeam comparatively firmly fixes on left socle and right support, and entrant is in the time can not crossing height crossbeam, and health is easy to be carried on a shoulder pole on crossbeam, can cause certain infringement to entrant.Moreover, if after left socle and right support be placed in not on the ground in same level, can make the run-off the straight of height crossbeam, be not easy whether level is demarcated to height crossbeam.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical problem, provides a kind of height crossbeam to be touched the track and field sports jumping stand falling.
Track and field sports jumping stand of the present utility model, comprise left socle, right support and height crossbeam, left socle, right support form by base and the vertical rod that is fixed on base, on vertical rod, be provided with the passive moving slider of height crossbeam, on vertical rod, be provided with the first gathering sill that moving slider is led; On vertical rod, be also provided with the scale value that highly horizontal depth of beam is demarcated; Its special feature is: on described moving slider, be provided with train wheel bridge, lower plate, the second gathering sill, clamping plate adjusting nut and slide block hold-down nut, between train wheel bridge and lower plate, form and cavity that highly crossbeam matches, lower plate is fixed on moving slider, train wheel bridge is placed in the second gathering sill, and clamping plate adjusting nut is fixedly connected with train wheel bridge and can orders about it and moves up and down; Slide block hold-down nut, for moving slider is fixed on to vertical rod, is provided with the height pointer paralleling with its lower surface on train wheel bridge.
Track and field sports jumping stand of the present utility model, the centre position of described height crossbeam is provided with the level meter whether paralleling with horizontal plane for characterizing its axis.
Track and field sports jumping stand of the present utility model, described moving slider is positioned at a side of vertical rod, and slide block hold-down nut is positioned at the opposite side of vertical rod, and hold-down nut is connected with moving slider screw thread through the first gathering sill.
The beneficial effects of the utility model are: track and field sports jumping stand of the present utility model, left socle, right support form by base and vertical rod, moving slider, by the cooperation of the first gathering sill and slide block hold-down nut, has been realized movement and the location of moving slider on vertical rod; By train wheel bridge and lower plate are set on moving slider, formed can be to a side opening of height cross beam support cavity, both realize comparatively firmly fixing to height crossbeam, also guaranteed that it can fall moment when sportsman touches highly crossbeam, and avoided sportsman to damage.By the second gathering sill and clamping plate adjusting nut are set on moving slider, can the distance between train wheel bridge and lower plate be regulated, to regulate train wheel bridge and add the hold dynamics of lower plate to height crossbeam.By the centre position at height crossbeam, level meter is set, by the observation to level meter, can quickly and efficiently height crossbeam be adjusted to horizontal level state.
