In this embodiment, the cross bar 201 is provided with two outer guide wheels 202 and two inner guide wheels 203, one end of the trigger rope 204 sequentially passes through one outer guide wheel 202 and one inner guide wheel 203 and then extends into one vertical rod 210, and the other end of the trigger rope 204 sequentially passes through the other outer guide wheel 202 and the other inner guide wheel 203 and then extends into the other vertical rod 204. When the trigger mechanism is installed, it is necessary to ensure that one set of outer guide wheels 202 and inner guide wheels 203 and the other set of outer guide wheels 202 and inner guide wheels 203 are respectively located on the cross bar 201 near the two ends. Meanwhile, in order to avoid the danger to the safety of athletes caused by the exposure of the outer guide wheel 202, a cover 205 is further installed on the cross bar 201, and the cover 205 is made of flexible materials and covers the outer guide wheel 202 inside.
In another embodiment, the number of the outer guide wheels 202 and the inner guide wheels 203 mounted on the cross bar 201 is one, and at this time, one end of the trigger rope 204 may be fixed on a side surface of one end of the cross bar 201, and the other end of the trigger rope passes through the outer guide wheels 202 and the inner guide wheels 203 at the other end of the cross bar 201 in sequence and then extends into one of the vertical bars 210.
The lower end of the vertical rod 210 is inserted into the base 100, the vertical rod 210 is located on the side surface inside the base 100 and is fixedly provided with a rotating shaft 211, and the rotating shaft 211 is rotatably arranged on the inner side surface of the base 100.
In this embodiment, the rotating shaft 211 is provided with a driving gear 212 and a torsion spring 213, and the driving gear 212 and the torsion spring 213 are respectively disposed on two sides of the vertical rod 210. Two ends of the torsion spring 213 are respectively fixed on the outer side surface of the vertical rod 210 and the inner side surface of the base 100, and when the cross rail 200 falls down under the action of gravity, the torsion spring 213 is compressed to provide power for the upward rotation of the cross rail 200.
The locking mechanism is installed in the position, close to the bottom end, inside the vertical rod 200, and comprises a locking rod 214 and a stop block 216, wherein the locking rod 214 is a Z-shaped rod and is rotatably installed on the inner side surface of the vertical rod 210. The side wall of the vertical rod 210 is provided with a through hole 215, one end of the locking rod 214 is located inside the vertical rod 210 and is fixedly connected with one end of the trigger rope 204 located inside the vertical rod 210, and the other end of the locking rod 214 penetrates through the through hole 215 and then extends into the base 100.
The stopper 216 is fixedly mounted on the inner side surface of the base 100 and is opposite to the end of the locking rod 214 located inside the base 100. The locking bar 214 is supported by the stopper 216 at an end thereof located inside the base 100, so as to prevent the cross rail 200 from rotating under the action of gravity. When the trigger rope 204 is triggered by the collision of the athlete, the trigger rope 204 drives the locking rod 214 to rotate upwards, so that the end of the locking rod 214 contacting with the stopper 216 is separated from the contact with the stopper 216, and at the moment, the barrier of the cross rail 200 disappears, and the cross rail can freely fall down around the rotating shaft 211 under the action of gravity.
In this embodiment, the side of the stopper 216 facing the vertical rod 210 is an inclined surface, and the elastic member is installed at the connection position of the locking rod 214 and the vertical rod 210, the elastic member provides the downward rotating elastic force of the locking rod 214, so that when the cross rail 200 rotates upward, the locking rod 214 is guided by the inclined surface of the stopper 216 to rotate upward, so that the elastic member is compressed, and when the locking rod 214 rotates to the maximum angle, the locking rod 214 also moves to the end of the stopper 216 just along with the rotation of the vertical rod 210, the stopper 216 presses the locking rod 214 to disappear, and the locking rod 214 rotates downward under the elastic force of the elastic member, so as to recover to the locking state.
Referring to fig. 5, a reset mechanism is installed inside the vertical rod 210. Because the interior of the vertical rod 210 also needs to be provided with a locking mechanism, in order to avoid the mutual influence between the locking mechanism and the reset mechanism, the interior of the vertical rod 210 is divided into two independent spaces by a partition plate extending along the axial direction, and the locking mechanism are respectively positioned in the two spaces.
The reset mechanism comprises a sliding block 220, a guide rod 221, a guide wheel 223 and a winding wheel 231, the sliding block 220 is located inside the vertical rod 210 and can slide along the axial direction of the vertical rod 210, the guide rod 221 is located above the sliding block 220, a reset rope 222 is connected to the sliding block 220, and the reset rope 222 bypasses the guide rod 221 and then extends downwards.
The guide wheel 223 rotates and is installed on the inner side surface of the vertical rod 210, the rolling wheel 231 is located outside the vertical rod 210 and is installed on the inner side surface of the base 100, and the guide wheel 223 and the rolling wheel 231 are located on the same plane. One end of the return string 222 extending downward is wound around the winding wheel 231 after passing around the guide wheel 223.
In this embodiment, the winding wheel 231 is coaxially fixed on the mounting shaft 230, and the mounting shaft 230 is rotatably mounted on the inner side surface of the base 100. The mounting shaft 230 is further coaxially and fixedly sleeved with a driven gear 232, the driven gear 232 is meshed with the driving gear 212, so that when the hurdle frame 200 falls down freely under the action of gravity, the driving gear 212 drives the driven gear 232 to rotate, the reset rope 222 wound on the winding wheel 231 is released due to the fact that the rotation directions of the two gears are opposite, and the sliding block 220 slides down under the action of gravity. In the process of downward rotation of the cross rail 200, the sliding block 220 slides downward all the time, and when the sliding block 220 slides below the rotating shaft 211, the sliding block 220 starts to block the rotation of the cross rail 200 until the cross rail 200 stops rotating because the weight of the sliding block 220 is greater than the weight of the cross rail 200 above the rotating shaft 211.
In another embodiment, the winding wheel 231 can be fixed inside the base 100 by the mounting shaft 230, and the reset rope 222 can be released or tightened when the vertical rod 210 rotates.
After the cross rail 200 stops rotating, the force applied to the vertical rod 210 includes the self-gravity, the gravity of the sliding block 220 and the elastic force of the torsion spring 213, and the gravity of the sliding block 220 is greater than the gravity of the portion of the cross rail 200 above the rotating shaft 211, and the elastic force of the torsion spring 213 rotating upwards is added, so that the cross rail 200 starts rotating upwards. In the process of upward rotation, the torsion spring 213 is slowly released, and meanwhile, the gravity difference caused by the upward movement of the slider 200 gradually decreases until the cross rail 200 rotates to the angle before falling down, at this time, the locking mechanism locks the cross rail 200, and the torsion spring 213 is also in a completely released state.
After the resetting mechanism is adopted, the cross railing 200 can be automatically reset after falling down, manual resetting is not needed, and the use is very convenient.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
