Abstract
The utility model relates to an automatic reset hurdle rack, which is a device for sports competitions and training. Hurdle sport is a sports item which is deeply welcomed, but higher injury risk exists when a person participates in the sport and the outstanding risk is that a sporter is injured after a supporting rack is driven to overturn after a hurdle plate is stressed and overturned. The utility model uses a bearing for connecting a hurdle plate rack with a vertical leg, the hurdle plate is forwards rotated together with the hurdle plate rack without driving the vertical leg to turn and incline when the hurdle plate is stressed, the hurdle plate rack is automatically reset to the original state under the action of gravity of a counterweight tube and an athlete is avoided from being injured. The utility model is favorable for the popularization and the development of the hurdle sport.
Description
Technical field
The utility model relates to a kind of physical education utensil.
Background technology
Hurdle campaign is a big event in the physical education, is highly profitable for the explosive force and the comprehensive sports quality that improve the sporter.But this motion has higher injury risk, and in match or the training, after the hurdle frame was knocked over down, its supporting leg was easy to the sportsman is damaged, thereby many beginners have a kind of fear to hurdle campaign, has influenced popularizing and development of this motion.
Summary of the invention
The utility model proposes a kind of automatic recovery frame of hurdling, its support is made up of upright leg and grillage two parts, the breast board frame in the similar past of structure of upright leg, a leg frame (9) and a stull (12) by (10) two symmetries of vertical rod of two symmetries constitute, a little bearing (11) respectively is equipped with in two vertical rods (10) upper end, generally can adopt the method for welding to install.Grillage is made up of breast board (1), fall way (3), connecting tube (6) and counterweight pipe (8), welding one short metal shaft (4) on connecting tube (6) tube wall, be used to be contained in bearing (11) lining on vertical rod top, fall way (3) lower end is injected the interior Yong of connecting tube (6) Ding Silk and is fixed, breast board (1) is installed with bolt (2) in fall way (3) upper end, connecting tube (6) lower end suit counterweight pipe (8), and Yong Ding Silk (7) connects.The scalable lift adjustment breast board of fall way (3) height, Yong Ding Silk (5) is fixing then.Counterweight pipe (8) can be regulated its position as requested, so that breast board is suitable to the reaction of counter-force.In training and competition, after in case plate washer is subjected to the external force overturning, grillage can not drive upright leg and tumble forward together, but be that fulcrum changes Xiang the Qian rotation with bearing (11), can return to original state again Xiang the grillage that the Qian rotation changes under the gravity effect of counterweight pipe (8), has avoided the injury that may cause the sportsman.
