Description

Technical Field

[0001] The utility model relates to the technical field of hurdle racks, in particular to a protective sports competition hurdle rack. Background Art

[0002] Hurdle race is a sprint event with certain technicality within a certain distance, crossing a specified number and height of hurdle racks, belonging to track events in track and field.

[0003] When participating in the hurdle event, the operator will place the hurdle rack on the track. At present, the height of the hurdle rack can be adjusted so that the athlete can cross the hurdle rack at the specified height. However, most of the current hurdle racks are fixedly installed, which means that the hurdle rack does not have a protective function. When the athlete collides with the hurdle rack during the hurdle race, the whole hurdle rack will tilt, and the tilted hurdle rack will lie on the track in front of the athlete, causing secondary injury to the athlete. Also, after the hurdle rack is hit, the operator needs to maintain it, which requires lifting the hurdle rack and placing it in the designated position. If the hurdle on the hurdle rack is deformed, the hurdle rack needs to be replaced, making it difficult for the hurdle rack to be quickly put into use, thus affecting the progress of the sports competition. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the existing hurdle rack is difficult to protect the athlete, and to propose a protective sports competition hurdle rack.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A protective sports competition hurdle rack, including a hurdle rack main body, the hurdle rack main body includes a positioning rack, a lifting cylinder, and a cross bar. A clamping seat is fixedly installed on the lifting cylinder, and a rotating shaft is rotatably installed on the clamping seat. The cross bar is arranged on the rotating shaft, and the two cross bars are arranged in a staggered manner. A limiting frame is fixedly installed on the clamping seat, and a pressure sensor and an alarm are electrically connected on the limiting frame. A pressing rod corresponding to the pressure sensor is arranged on the cross bar.

[0007] Preferably, the rotating shaft is vertically arranged, and a guiding frame is integrally connected to the rotating shaft.

[0008] Preferably, the guiding frame and the rotating shaft extend to the upper end position outside the clamping seat, and a stress inclined surface is opened on the guiding frame. The limiting frame is horizontally arranged on one side of the clamping seat.

[0009] Preferably, a slider is slidably sleeved in the limiting frame, and a moving plate is integrally connected to the slider. A reset frame for resetting the guiding frame is fixedly installed on the moving plate. A spring is welded between the moving plate and the limiting frame. A telescopic rod connected to the moving plate is fixedly installed on the clamping seat.

[0010] Preferably, the reset frame and the moving plate extend to the upper end position outside the limiting frame, and the spring is horizontally welded.

[0011] Preferably, the reset frame is of a U-shaped structure, and a pressing inclined surface corresponding to the guiding frame is provided on the reset frame.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. By arranging the two cross bars in a staggered manner, the cross bars can be disconnected and deflected after being impacted, avoiding secondary injuries to the contestants caused by the inclination resulting from the integral connection of the cross bars. After deflection, the cross bars can open to enable the contestants to continue moving forward, endowing the hurdle frame main body with a certain protective function.

[0014] 2. By arranging the guiding frame on the rotating shaft and resetting the guiding frame through the movement of the reset frame, the guiding frame can drive the cross bar to synchronously deflect to the initial position during movement, enabling the hurdle frame main body to be quickly put into use, thereby reducing the working intensity of the operator.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Refer to Figures 1-5 , a protective sports competition hurdle, including a hurdle main body, the hurdle main body includes a positioning frame 1, a lifting cylinder 2, and a crossbar 3. Place the hurdle main body on the competition field so that the positioning frame 1 can be connected to the ground, and the lifting cylinder 2 can adjust the height of the crossbar 3;

[0023] A clamping seat 4 is fixedly installed on the lifting cylinder 2, and a rotating shaft 5 is rotatably installed on the clamping seat 4. The crossbar 3 is arranged on the rotating shaft 5, and the two crossbars 3 are arranged in a staggered manner. As shown in the attached drawings of the specification Figure 1 , the two crossbars 3 are in a staggered state. Before the competition, the operator needs to detect the state of every two crossbars 3 to ensure that the crossbars 3 can automatically deflect after being hit by force;

[0024] A limiting frame 7 is fixedly installed on the clamping seat 4, and a pressure sensor 8 and an alarm 9 are electrically connected on the limiting frame 7. A pressing rod 10 corresponding to the pressure sensor 8 is arranged on the crossbar 3. When the crossbar 3 is hit, the pressing rod 10 is disconnected from the pressure sensor 8. After the force value of the pressure sensor 8 is lower than the specified threshold, an instruction is immediately sent to the alarm 9 to enable the alarm 9 to prompt the referee;

[0025] A guiding frame 6 is integrally connected to the rotating shaft 5, and a force-receiving inclined surface is provided on the guiding frame 6. The rotating shaft 5 is arranged vertically, and the guiding frame 6 and the rotating shaft 5 extend to the upper end position outside the clamping seat 4. The limiting frame 7 is horizontally arranged on one side of the clamping seat 4;

[0026] A slider 11 is slidably sleeved in the limiting frame 7, and a moving plate 13 is integrally connected to the slider 11. A reset frame 14 for resetting the guiding frame 6 is fixedly installed on the moving plate 13. A spring 12 is welded between the moving plate 13 and the limiting frame 7. The spring 12 plays a buffering role for the moving plate 13 so that the slider 11 will not generate a large impact with the limiting frame 7 when moving;

[0027] The reset frame 14 and the moving plate 13 extend to the upper end position outside the limiting frame 7, and the spring 12 is horizontally welded. The reset frame 14 is of a U-shaped structure, and a pressing inclined surface corresponding to the guiding frame 6 is provided on the reset frame 14;

[0028] By contracting the output end of the telescopic rod 15, the moving plate 13 drives the reset frame 14 to extend onto the guide frame 6, and the pressure application inclined surface on the reset frame 14 corresponds to the force receiving inclined surface on the guide frame 6, thereby adjusting the angle of the guide frame 6. When the angle of the guide frame 6 is adjusted, it can drive the cross bar 3 to run synchronously, and the cross bar 3 can quickly deflect to the initial position, so that the hurdle frame main body can quickly be put into use in the competition.

[0029] The functional principle of the present utility model can be described through the following operation methods:

[0030] Before a sports competition;

[0031] The operator places a group of hurdle frame main bodies on the playing field and adjusts the height of the cross bar 3 through the lifting cylinder 2 so that the two cross bars 3 are in a staggered state. The operator first impacts the two cross bars 3 to ensure that the cross bars 3 can be disconnected after being impacted;

[0032] During a sports competition;

[0033] When the athlete's leg impacts the cross bar 3, the cross bar 3 deflects forward under the force, and the cross bar 3 drives the rotating shaft 5 to rotate in the card seat 4. The connection points of the two cross bars 3 are disconnected during deflection, and the athlete can continue to move;

[0034] At the same time, when the cross bar 3 deflects, it drives the guide frame 6 and the pressure application rod 10 to rotate synchronously. When the pressure application rod 10 deflects, it disconnects from the pressure sensor 8. After the pressure sensor 8 is stressed below the specified threshold value, it immediately issues an instruction to the alarm 9, causing the alarm 9 to emit a warning light, and the referee judges the athlete's hurdle performance;

[0035] When the cross bar 3 deflects to a certain extent, it will collide with one side of the card seat 4, and the cross bar 3 is intercepted by the card seat 4 to deflect back a certain angle. Then the output end of the telescopic rod 15 contracts, and the output end of the telescopic rod 15 drives the moving plate 13 and the slider 11 to move. The spring 12 is stressed, so that when the slider 11 slides in the limit frame 7, it can drive the reset frame 14 to gradually approach the guide frame 6, so that the pressure application inclined surface on the reset frame 14 can extend onto the force receiving inclined surface on the guide frame 6;

[0036] When the reset frame 14 fully extends onto the guide frame 6, the guide frame 6 drives the rotating shaft 5 and the cross bar 3 to rotate, so that the two cross bars 3 return to the initial position;

[0037] The output end of the telescopic rod 15 expands and contracts to disconnect the reset frame 14 from the guide frame 6, and the hurdle frame main body can be used again.

[0038] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
