Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A high-safety combined football frame comprises a first upright post 1, a second upright post 2 and a cross beam 3; the cross beam 3 comprises a first fixing piece 31, a second fixing piece 32 and a central rod 33; the first fixing piece 31 is arranged at the top of the first upright post 1; the second fixing piece 32 is arranged at the top of the second upright post 2; two ends of the center rod 33 are respectively rotatably connected with the first fixing piece 31 and the second fixing piece 32; a buffer sleeve 34 is coated and arranged on the outer side of the central rod 33; the buffer sleeve 34 rotates synchronously with the central rod 33; the cushion sheath 34 includes a first half-shell 341 and a second half-shell 342; first half shell 341 and second half shell 342 are sectioned by a plane passing through the axis of symmetry of central bar 33; the first half shell 341 is made of hard material; second half shell 342 is made of soft material; during ordinary training, the central rod 33 is rotated to enable one side of the second half shell 342 to face the direction of the ground, so that when a ball shoots the lower half side of the central beam 3, a football which should be shot into the goal quickly is deformed by the second half shell 342 to lose a large amount of kinetic energy, so that the shooting speed is reduced, and a goalkeeper is prevented from being injured by hitting vital parts due to untimely response; when a match is played, the central rod 33 is rotated to enable one side of the first half shell 241 to face the direction of the ground, and at the moment, when the ball shoots the lower half side of the central beam 3, the force cannot be removed, so that the shooting track and speed of the ball are ensured to be unchanged, and the fairness of the match is ensured; the design of soft and hard switching can reduce the risk of accidental injury in the training process of a goalkeeper, and is particularly suitable for the training of a new goalkeeper.

The two ends of the center rod 33 are provided with limit lugs 331; one side of the first fixing piece 31 facing the central rod 33 is provided with a first limiting groove 311; a second limiting groove 321 is formed in one side, facing the central rod 33, of the second fixing member 32; the limiting lug 331 is respectively nested and matched with the first limiting groove 311 and the second limiting groove 321 on the corresponding side; the cross section of the limiting lug 331 is specifically in a rectangular shape and other figures, so that when the limiting groove is matched, the rotation of the central rod 33 can be restrained, and the installation stability of the cross beam 3 is ensured.

A first auxiliary frame 5 and a second auxiliary frame 6 are arranged on one side of the cross beam 3, which is back to the forecourt; the first auxiliary frame 5 is hinged with the first fixing piece 31; the second auxiliary frame 6 is hinged with a second fixing part 32; the first auxiliary frame 5 and the second auxiliary frame 6 are connected at one ends far away from the cross beam, and a counterweight seat 7 is arranged at the junction; the bottom of the counterweight seat 7 is in contact with the ground, and a plurality of counterweight blocks 71 are superposed above the counterweight seat, so that the integral gravity center of the ball frame can move downwards, and the stability of the integral structure is enhanced.

The bottoms of the first upright post 1 and the second upright post 2 are respectively embedded with a first positioning drill rod 101 and a second positioning drill rod 102 in a sliding manner; the first positioning drill rod 101 and the second positioning drill rod 102 are driven downwards into the ground to form a three-pivot structure with the counterweight seat 7; because the ball frame is a facility which is not moved frequently, the lawn is damaged negligibly by adopting a mode that the positioning drill rod penetrates into the lawn at the corresponding mounting position.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
