Embodiment Construction

[0013] The device of the present invention is proposed in order to avoid the problem that the current hurdle race hurdle frame is prone to side shifting and hurting people on the plastic track. The main structure of the device of the present invention is as follows figure 1 , figure 2 As shown, the fixed connection between its specific structure and the plastic runway, and the connection with the hurdle frame have the following characteristics: the front end of the fixed plate 4 is welded and connected to the hanging rod 3, and six oblique spike nails 6 are installed under the fixed plate 4. Tip obliquely plunges into below the plastic runway line 5 and fixes the fixed plate towards the running direction. The rear rings of the left extension spring 2 and the right extension spring 8 are hung on the hanging rod 3, and the front rings are respectively hung on the left adhesive chain tape 1 and the right adhesive chain tape 7. The left adhesive chain belt 1 and the right adhesi...

Abstract

The invention belongs to the field of sports equipment, in particular to a device for preventing a hurdle frame from side shifting on a synthetic track in hurdle races, which comprises a fixing plate (4) and a hook rail (3), wherein the hook rail (3) is arranged on the front end on the upper part of the fixing plate (4), and is provided with a left tension spring (2) and a right tension spring (8); the other end of the left tension spring (2) is provided with a left sticky chain belt (1); the other end of the right tension spring (8) is provided with a right sticky chain belt (7); the lower part of the fixing plate (4) is provided with six inclined nails (6) for fixing the fixing plate on a track; and the nail point directions of the inclined nails (6) accords to a running direction. During the short moment for buffering movement when a hurdle frame is knocked over and falls forwards or sidewards, the tension force of the left tension spring (2) and the right tension spring (8) is about to pull the hurdle frame back to the original place so that the phenomenon that athletes are hurt because of the hurdle frame moving sidewards to an adjacent track is avoided.

Description

technical field [0001] The invention belongs to the field of sports, and in particular relates to a device for preventing a hurdle frame from shifting on the side of a plastic track used in hurdle competitions. Background technique [0002] In a hurdle race, the hurdle frame is likely to fall forward or move sideways to the adjacent track. The hurdle frame shifts sideways to the adjacent track, and it often happens that the ends of the two bases injure the athletes on the adjacent track. This is a problem that has plagued the sport and has not been properly resolved. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a device for preventing the displacement of the hurdle frame on the side of the plastic runway. The technical solution adopted is a device for preventing the displacement of the hurdle frame on the side of the plastic runway. The hanging rod at the front end above the fixed plate, the left extension spring ...
