Abstract

The invention provides a high jump stand capable of being automatically adjusted, and belongs to the technical field of sports equipment. The device comprises an upper column, a lower column, a screw, a height limiting assembly and a lifting assembly, the upper column is fixed to the top of the lower column through a bolt, the top of the upper column is rotationally connected with a lifting wheel, a lower positioning plate is fixed to the inner wall of the lower column, an upper positioning plate is fixed in the upper column, and the screw penetrates through and is rotationally connected to the upper positioning plate and the lower positioning plate. The height limiting assembly comprises a jumping rod supporting seat for placing a jumping rod and a height limiting plate, the lifting assembly comprises a motor, a pushing plate, a mounting plate, a lifting frame and a jumping rod supporting seat, the height limiting plate adjusts the height through the lifting assembly to realize automatic adjustment, the lifting assembly can always apply an upward pulling force to the jumping rod supporting seat, and when an athlete touches the jumping rod to fall off, the jumping rod can be automatically lifted. Upward buffering force is exerted on an athlete, the jumping rod supporting seat is adjusted to reset in time, and secondary adjustment is not needed. The automatic game machine is high in automation degree, labor-saving, good in safety performance and capable of improving game efficiency.

Description

Technical field [0001] The present invention belongs to the field of sports apparatus technology, relates to a height-adjustable jumping height. Background [0002] High jump is one of the athletics competitions in athletics, is the human body through the running, jumping, vacating, landing series of action forms to jump over the height of the obstacle sports, the traditional jump high, need people to adjust the height of the jumper, more troublesome. [0003] Application number CN201620876700.1 utility model patent discloses a kind of sports training with a high jump, this technology of the high jump pole to achieve the automatic height adjustment of the crossbar, but if the athlete action is not standard or did not jump over the crossbar, the athlete is easy to touch the crossbar when falling and fall, easy to cause athletes to be injured, there is no relevant protection for athletes when landing safety facilities, while athletes fall and bump the crossbar, it is easy to cause...

Problems solved by technology

[0003] The utility model patent with the application number CN201620876700.1 discloses a high jump frame for sports training. The high jump bar of this technology realizes the automatic height adjustment of the cross bar. When falling, it is easy to touch the crossbar and fall, which is likely to cause injury to the athletes. There are no safety facilities to protect the athletes when they land. At the same time, when the athletes fall and hit the crossbar, it is easy to cause the height of the crossbar to drop and need to be readjusted, which is very inconvenient , which will lead to a lot of time wasted on height adjustment
