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
The invention belongs to the sports field, particularly a kind of use when being used for hurdle race prevent the device of frame of hurdling in the displacement of plastic cement race track side.
Background technology
In hurdle race, the frame of hurdling is bumped easily overturning forward or is displaced to adjacent runway to side.The frame of hurdling is displaced to adjacent runway to side, through regular meeting the sportsman that two base terminations injure adjacent runway is taken place, and this is the problem that this motion of puzzlement is never properly settled.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of device of frame in the displacement of plastic cement race track side that prevent to hurdle, the technical scheme that is adopted is a kind of device of frame in the displacement of plastic cement race track side that prevent to hurdle, this device comprises fixed head and is arranged on the peg of front end above the described fixed head, Zola's spring and right extension spring are set on the described peg, the other end of described Zola's spring is provided with the sticking chain belt in a left side, and the other end of described right extension spring is provided with right sticking chain belt; The following installation of described fixed head makes it be fixed on six oblique spikes on the runway, and the nail point direction of described oblique spike is consistent with the direction of running.
Sticking chain belt in a described left side and the right chain belt that glues are hurdled bonding connection of left column of frame with first right column and second of hurdling frame respectively.
The invention has the beneficial effects as follows: one, the left and right sticking chain belt and two of this device frame column of hurdling is certain loose scope and is connected, the nonintervention forward overturning of frame when being reached 3.6 to 4 kilograms by impact force of hurdling.Two, the frame of hurdling is bumped can produce after the overturning forward and moves forward or be stretched to side shifting tractive Zola's spring and right extension spring, and this stretching buffering course can be avoided that the sportsman is formed stiff mixing and fall.Three, the moment of short duration after above-mentioned Zola's spring and right extension spring are stretched, its pull-back forces can retract original position with the frame of hurdling, and the frame side of having avoided hurdling is displaced to adjacent runway base termination and injures the sportsman.Four, six oblique spikes are installed below fixed head, the oblique direction of running of nail point is pricked into below the plastic cement race track line, the pulling force forward in the time of resisting the frame of hurdling and bumped overturning forward and obliquely pulling force spur fixed head, this is the crucial innovative point of this device.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
Fig. 1 prevents to hurdle the front view of frame at the device of plastic cement race track side displacement;
Fig. 2 prevents to hurdle the vertical view of frame at the device of plastic cement race track side displacement;
Fig. 3 is that Fig. 1 prevents to hurdle frame at the device of plastic cement race track side displacement and schematic diagram after the frame of hurdling is connected;
Fig. 4 is that Fig. 2 prevents to hurdle frame at the device of plastic cement race track side displacement and schematic diagram after the frame of hurdling is connected.
Fig. 5 is that Fig. 3 prevents to hurdle frame in the overturning or retract the schematic diagram of original position to the frame of hurdling of side displacement forward of the device of plastic cement race track side displacement.
Fig. 6 is that Fig. 4 prevents to hurdle frame in the overturning or retract the schematic diagram of original position to the frame of hurdling of side displacement forward of the device of plastic cement race track side displacement.
The specific embodiment
Apparatus of the present invention are for avoiding the existing hurdle race frame of hurdling to be prone to the problem that side displacement hurts sb.'s feelings at plastic cement race track and to propose, the agent structure of apparatus of the present invention as shown in Figure 1 and Figure 2, the fixedlying connected of its concrete structure and plastic cement race track, with hurdle the following feature of being connected with of frame: front end is welded to connect peg 3 on described fixed head 4, six oblique spikes 6 are installed below fixed head 4, and the oblique direction of running of nail point is pricked into plastic cement race track line 5 following fixedly fixed heads.The back ring of described Zola's spring 2 and right extension spring 8 is hung on peg 3, and its preceding ring is hung on sticking chain belt 1 in a left side and right sticking chain belt 7 respectively.Sticking chain belt 1 in a left side and right sticking chain 7 are with respectively with first right column 9 and second of hurdling frame and are hurdled 12 bonding connections of left column of frame, as shown in Figure 3, Figure 4.
Claims (2)
1. the device of frame that prevent to hurdle in the displacement of plastic cement race track side, it is characterized in that: this device comprises fixed head (4) and is arranged on the peg (3) of front end above the described fixed head (4), Zola's spring (2) and right extension spring (8) are set on the described peg (3), the other end of described Zola's spring (2) is provided with the sticking chain belt (1) in a left side, and the other end of described right extension spring (8) is provided with right sticking chain belt (7); The following installation of described fixed head (4) makes it be fixed on six oblique spikes (6) on the runway, and the nail point direction of described oblique spike (6) is consistent with the direction of running.
2. the frame that prevents to hurdle according to claim 1 is characterized in that at the device of plastic cement race track side displacement: a described left side glue chain belt (1) and the right side and is glued chain belt (7) and hurdle bonding connection of left column (12) of frame with first right column (9) and second of hurdling frame respectively.
