High jump stand rod device with automatic reset function and use method thereof

Abstract

The invention discloses a high jump stand rod device with an automatic reset function. The device comprises a base, a small cylinder end, a transverse turning head, a longitudinal turning head and a transverse rod sleeve; the device is characterized in that direction arrows are arranged on the bases, and the direction arrows on the left base and the right base are in a mirror image relation; a bottom cylinder is arranged in the middle of the base; a bottom knob is arranged on the bottom cylinder; the middle cylinder is inserted into the bottom cylinder, and clamping of the middle cylinder by the bottom cylinder can be fixed or loosened by rotating the bottom knob; a small cylinder groove is formed in the side surface of the small cylinder and is matched with a convex groove formed in the middle cylinder, so that the small cylinder can only move up and down in the middle cylinder; and a small cylinder end is arranged at the top end of the small cylinder, and a transverse limiting head is arranged on one side of the small cylinder end. According to the principle that opposite poles of the magnets attract each other and the spring can automatically reset within a certain deformation range, the use and installation difficulty is lowered, and the use efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a high jump pole device with an automatic reset function. Background technique [0002] High jump is one of the field events of track and field sports. It is composed of rhythmic approach, jumping with one foot, and landing over the high jump pole. The score is calculated by the height above the upper edge of the high jump pole. To high jump apparatus, the high jump apparatus that prior art makes all has defective in various degree. [0003] For example: the beneficial effect of the patented technology "a kind of sports training equipment for high jump" (authorized announcement number: CN212038748U) of Fujian Shipping Vocational College is "connecting two high jump poles through the first magnet and the second magnet, when the athlete's high jump height When it is not enough to touch the high jump pole, give the high jump pole a downward force to separate the two high j...

AI Technical Summary

Problems solved by technology

However, due to structural design defects, this patent cannot cope with the lateral impact of high jumpers on the high jump pole due to insufficient take-off height. There is a risk of injury caused by the high jumper's lateral impact on the high jump pole. Press down until it sags more than 45 degrees. When "the high jump bar then returns to its original position under the action of the elastic hinge", how to deal with the inertia of the high jump bar, how to ensure that the high jump bar just returns to the horizontal state, how to ensure that the first magnet and the second The alignment of two magnets, etc., the patent does not involve

[0004] The patented technology "A Crossbar for High Jump" (authorized announcement number: CN202398019U) of the Sports Department of Heilongjiang University of Science and Technology divides the crossbar into multiple sections. When the unit or the end face is connected, one end of the spring piece will slide out of the counterbore, and the two ring-shaped magnetic pieces will be disconnected quickly. There is a risk of injury and reinstallation will not be quick

[0005] Qiqihar University's patented technology "A High Jump Rack for Training" (authorized announcement number: CN204932699U), the beneficial effect of this patent is based on the premise that athletes can only touch the middle bar when they pick up and fall. If the player falls and touches the end crossbar, because the end crossbar is fixed, it is inevitable for the athlete to be injured; and when the athlete presses the middle crossbar to sag more than 60 degrees, it will cause the spring in the end crossbar to deform; the middle crossbar Horizontal reset is hard to do

[0006] Hubei Normal University's patented technology "New High Jump Pole with Anti-injury for Teaching and Training" (authorized announcement number: CN204952049U), this technology has the possibility that after the middle pole is touched by the athlete and falls, the end pole hangs on the Velcro and sloshes and hits the athlete It is not very fast to grab the left and right end rods when resetting, and there is no buffer design when the magnetic blocks attract each other. The magnetic blocks may be crushed and damaged. According to the description of the patent specification and the accompanying drawings, the two end rods The end of the crossbar is fixed with Velcro, and the end pole will shake outdoors when there is wind, and the height of the entire crossbar will also fluctuate, which will cause athletes to make mistakes in judgment and affect training performance

[0007] "A high jump regulator for sports training" (authorized announcement number: CN205391544U0) of the School of Physical Education of Hexi University. This patent uses the counterweights on both sides to straighten the drawstring. When falling down, there is a danger of being tripped and injured by the pull rope; when the pull rope is quickly reset, the collision and extrusion of the magnet will be accelerated, which can neither ensure the correct alignment of the two magnet blocks, but also easily shatter and damage the magnet

[0008] The patented technology "A high-jump frame for height adjustment" (authorized announcement number: CN207055778U) only considers the lateral impact force of the athlete's high jump hitting the crossbar, but ignores the vertical impact force of the athlete's high jump hitting the crossbar, which has no application value
