Preferably, the bolt 6, the nut 7 on the right side of the bolt 6, the buffer 307 in the middle of the overlapping column 304 and the sealing gaskets 308 on the two sides of the bolt 6 jointly form an overlapping mechanism, because the cross rod 2 is placed on the overlapping column 304 of the support column 3, the buffer 307 is arranged inside the overlapping column 304 and is made of rubber with good resilience, the buffer 307 can prevent the cross rod 2 from generating excessive collision force when being placed on the top of the overlapping column 304, the cross rod 2 is connected with the overlapping column 304 through the bolt 6 and the nut 7, and because most of the bolt 6 is embedded into the cross rod 2 and the overlapping column 304, the sealing gaskets 308 are arranged on the part of the overlapping column 304, which is attached to the bolt 6, the sealing gaskets 308 are made of rubber with good sealing effect, gaps between the overlapping column 304 and the bolt 6 or the cross rod 2 can be filled, so that external water cannot flow into the bolt 6 from the gaps, and because of the unable water laminating with the external world of bolt 6, so bolt 6 can not produce when using because of water and corrode, corresponding sealed pad 308 also plays better protectiveness to bolt 6 for bolt 6's life greatly increased, thereby overlap joint mechanism's setting also is convenient for the training person and fixes the use between horizontal pole 2 and the support column 3 better.

The working principle is as follows:

firstly, as the whole hurdle frame 1 is placed on the ground through the base 5, the bottom end of the base 5 is provided with the uneven anti-slip patterns 502, and the anti-slip patterns 502 can greatly increase the friction force at the bottom of the base 5, so that the stability of the base 5 during placement can be increased, and the whole hurdle frame 1 is not easy to displace when placed through the base 5;

then, because the cross bar 2 is placed on the lap joint column 304 of the support column 3, a buffer pad 307 is arranged inside the lap joint column 304, the buffer pad 307 is made of rubber with good resilience, the buffer pad 307 can prevent the cross bar 2 from generating excessive collision force when being placed on the top of the lap joint column 304, the cross bar 2 is connected with the lap joint column 304 through a bolt 6 and a nut 7, most of the bolt 6 is embedded into the cross bar 2 and the lap joint column 304, a sealing pad 308 is arranged at the part of the lap joint column 304, which is attached to the bolt 6, the sealing pad 308 is made of rubber with good sealing effect, a gap between the lap joint column 304 and the bolt 6 or the cross bar 2 can be filled, so that external water cannot flow into the bolt 6 from the gap, and the bolt 6 cannot be attached to the external water, the bolt 6 cannot be corroded due to the water when being used, and the corresponding sealing pad 308 has good protection performance on the bolt 6, the service life of the bolt 6 is greatly prolonged, so that the arrangement of the lapping mechanism is convenient for a trainer to fix the cross rod 2 and the support column 3;

then, due to different conditions during use, the height of the cross rod 2 is different, the trainer needs to change the height of the cross rod 2, the bayonet lock 303 at the position of the connected support column 3 needs to be screwed out anticlockwise, so that no connectivity exists between the telescopic cylinder 301 and the telescopic rod 302 of the support column 3, the trainer can hold the telescopic rod 302 to drive the top end cross rod 2 to move up and down, after the upper end cross rod moves to a proper height, the trainer can screw the bayonet lock 303 into the telescopic cylinder 301 to extrude and fix the telescopic rod 302, the situation that the telescopic rod 302 moves up and down in the telescopic cylinder 301 is avoided, and therefore the bayonet lock 303 is convenient for the trainer to adjust and fix the height of the cross rod 2;

next, when a trainer performs hurdle training, the collision force received at the top of the whole hurdle 1 can be converted into vibration force to be transmitted to the supporting column 3, then the telescopic cylinder 301 at the bottom of the supporting column 3 can drive the limiting plate 305 to transmit the vibration force to the vibration reduction box 4, and the vibration reduction box 4 is connected and fixed with the limiting plate 305 through the spring 401, so that the vibration force transmitted by the limiting plate 305 can be offset by the spring 401 through resilience force, the vibration force transmitted to the base 5 by the vibration reduction box 4 is greatly reduced, and the weighting block 501 is arranged at the base 5, so that the vibration force of the base 5 after being weakened cannot generate the condition of swinging displacement, the arrangement of the vibration reduction mechanism avoids the displacement and turnover of the whole hurdle 1 due to the collision of the trainer, and the stability of the whole hurdle 1 when placed is greatly improved;

finally, because of limiting plate 305 is greater than the hole at 4 tops of damping case, limiting plate 305 outer wall can reciprocate along 4 inner walls of damping case under spring 401's drive, and in order to avoid limiting plate 305 outer wall to produce the friction when removing, so be equipped with rollable steel ball 306 in the both sides of limiting plate 305, steel ball 306 can separate between limiting plate 305 and the 4 inner walls of damping case, make unable direct laminating friction between limiting plate 305 outer wall and the 4 inner walls of damping case, avoided limiting plate 305 outer wall to produce wearing and tearing because of reciprocating along 4 inner walls of damping case, this kind of physical training device for physical training's theory of operation is exactly.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
