Embodiment Construction

[0031] Such as Figure 1 to Figure 8As shown, a non-injurious automatic closed hurdle frame includes two bases 3, two uprights 2, a beam 4 and a fence. At the front end, two bases are arranged in parallel, two uprights are arranged in parallel, and the lower ends of the uprights are connected with the front end of the corresponding base. In the left and right directions, the fence is divided into left section 1 and right section, both left and right sections are retractable fences in the left and right directions, and the right end of the left section and the left end of the right section are all provided with magnets 6 that make them form a suction connection . The left section is connected to the top of the column on the left through the left torsion spring 5, the upper end of the left torsion spring is fixedly connected to the left section, the lower end of the left torsion spring is fixedly connected to the column on the left side, and the left torsion spring is sleeved o...

Abstract

The invention provides a harmless auto-closing hurdle, comprising two bases, two pillars, a cross beam and a board. The board includes a left segment and a right segment in left-right direction, both the left segment and the right segment are telescopic boards in the left-right direction, and both the right end of the left segment and the left end of the right segment are arranged to form magnets that are available for suction connection; the left segment is connected with the top end of the left pillar through a left torsion spring, the right segment is connected with the top end of the right pillar through a right torsion spring, both left and right sides of the upper surface of each base form inserts raised upward, both the left and right faces of each base form grooves for receiving the inserts, and when one base is overlaid on the other, the inserts of the lower base are inserted into the corresponding grooves of the upper one.

Description

technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to a hurdle frame, more specifically, to a non-injurious automatic closing type hurdle frame. Background technique [0002] The hurdle race originated in England. From the 17th to the 18th centuries, animal husbandry was quite developed in some areas of the UK, and herdsmen often needed to cross the corrals to chase escaped livestock. During the festival, some lively young herdsmen often hold a game of jumping over the sheepfold. They move the fence to the flat ground and set up several obstacles with the same height and height as the sheepfold to see who can run in the front. This is the hurdle race. prototype [0003] At the 1990 Beijing Asian Games, Chinese player Liu Huajin broke her own Asian record of 12.89 seconds in the women's 100-meter hurdles with a time of 12.73 seconds. Chinese player Liu Xiang tied the record of 12.91 seconds in the 2004 Athens Olympics. ...
