Abstract
The utility model relates to an automatic reset hurdle support which comprises a base. A hurdle support body is arranged on the base and comprises a transverse rod and two vertical rods fixedly arranged below the transverse rod. A protection strip is arranged above the transverse rod of the hurdle support body and is inserted in the transverse rod of the hurdle support body. A groove is formed in the top portion of the transverse rod of the hurdle support body. A protruding piece matched with the groove is arranged on the bottom portion of the protection strip. A plurality of locating holes are formed in the vertical rods of the hurdle support body. A gravity ball is arranged on the bottom portion of each vertical rod of the hurdle support body. The height of the hurdle support can be adjusted through adjusting position relations of the locating holes and locating pins. According to the protection strip arranged on the top portion of the hurdle support, ankles and other articulations are effectively prevented from being hurt when a player kicks the hurdle support. When the hurdle support is righted, action of the gravity balls drives the hurdle support body to reset automatically so that the automatic reset hurdle support is time-saving and labor-saving in usage.
Description
Technical field
The utility model relates to a kind of hurdles rack, and is a kind of in that hurdle can automatically reset hurdles rack after translating into specifically, belongs to the sports apparatus field.
Background technology
The hurdle race campaign originates from Britain, and in 18 end of the centurys, the activity of hurdling formally becomes sports item.People were called handicap run to it at that time, belonged to man's sports events, and the barrier of setting is general fence, wooden hurdle frame on the ground occurred afterwards being embedded in, changed into again afterwards again, the support of using as the sawmilling material, but cross over this barrier, injury accident not only occurs easily, and hinder the raising of hurdle race technology, so hurdle race allows sportsmen feel hidden danger in early days always, for this reason, " ⊥ " shape hurdle frame has appearred movably in 19 beginnings of the century, has promoted the development of hurdling technique.In the nineteen thirty-five match " L " shape hurdle frame has appearred again, as long as breast board is subjected to 4 kilograms collision strength, forward overturning.The comparatively reasonable and safety of " L " shape structure is used till today always.Hurdle race is in certain distance, strides across the height of regulation and the hurdle frame of quantity, technical stronger sprint events.In the present race, the international tournament man is 110 meter high hurdle, and the hurdle is high 106 centimetres, 10 of column numbers; The woman is M 100 low hurdles, and the hurdle is high 84 centimetres, 10 of column numbers.
In the hurdle race exercise; often the phenomenon that the sportsman kicks hurdles rack can appear; the cross bar of hurdling is very hard; be easy to position injuries such as athletic ankles, athletic physiology and mental health are caused certain burden, and need to be with the hurdles rack righting that kicks down before the use of next time; and the hurdling when righting of " L " shape; need to bend over the righting of hurdling, then adjust the position of hurdling, increase labour intensity.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automatically reset hurdles rack, can automatically reset after translating into hurdling.
For addressing the above problem, the utility model by the following technical solutions:
A kind of automatically reset hurdles rack, comprise base, it is characterized in that: described base is provided with the hurdle frame, described hurdle frame comprises cross bar and two montants that are fixedly installed on the cross bar below, and the top of described hurdle frame cross bar is provided with security bar, and described security bar is inserted on the cross bar of hurdle frame, the top of described hurdle frame cross bar is provided with groove, described security bar bottom is provided with the projection with groove fit, and the montant of described hurdle frame is provided with several locating holes, and the bottom of described hurdle frame montant is provided with gravitation ball.
Below be further improvement of these options:
Described base and hurdle frame are rotationally connected by locating hole and alignment pin.
Described base comprises two T shape seats, is fixedly connected with by bar between the T shape seat.
The utility model compared with prior art, has following characteristics: can be by adjusting the position relationship of locating hole and alignment pin, control the height of hurdles rack, the security bar of installing at the hurdles rack top simultaneously can effectively prevent when the sportsman kicks hurdles rack the damage to joints such as ankles, and being rotationally connected of hurdle frame and base, so that the independent overturning of hurdle frame, base maintains static, and by the effect automatic traction hurdle frame playback of gravitation ball, it is time saving and energy saving to use when righting.
The utility model is described in further detail below in conjunction with drawings and Examples:
