The utility model discloses football training rebound board, including rebound board, set up on the mounting seat of rebound board and the support frame of rotation setting on the mounting seat, and mounting seat has swing groove and support frame rotation setting in swing groove and swing in swing groove to adjust support angle, the lateral wall of swing groove is equipped with arc recess, and the groove bottom of recess is equipped with a plurality of round array distribution's pinhole, and is equipped with with elastic pin on the support frame, and elastic pin is in natural state and extends into pinhole to limit support frame, and when limiting, support frame and rebound board contact ground together and make the rebound surface of rebound board be in specific football rebound angle, wherein annular array and the center of arc recess all are located on the rotation axis of support frame. The angle adjusting operation of this application is more convenient, and the rotation of support frame is also more smooth.

Claims

1. A football training rebound plate, comprising a rebound plate, a mounting base disposed on the rebound plate, and a support frame rotatably disposed on the mounting base, characterized in that: The mounting base has a swing groove, and the support frame is rotatably mounted in the swing groove and swings within the swing groove to adjust the support angle. The side wall of the swing groove has an arc-shaped groove, and the bottom of the groove has several circularly arranged pin holes. The support frame is equipped with an elastic pin. In its natural state, the elastic pin extends into the pin hole to limit the support frame. When the support frame and the rebound plate are in contact with the ground, the rebound surface of the rebound plate is at the set football rebound angle. The center of the annular array and the arc-shaped groove are both located on the rotation axis of the support frame.

2. The football training rebounder board of claim 1, wherein, The support frame is a flat-bottomed U-shaped frame with a telescopic structure. Both ends of the U-shaped frame are steel pipes, each including an upper and lower pipe body. The lower pipe body is fitted onto the upper pipe body, and at least one locking structure is provided between the upper and lower pipe bodies. The locking structure includes an annular step at the lower end of the upper pipe body, a spring fitted onto the annular step, an elastic pin inside the upper pipe body, and several sets of locking holes on the lower pipe body. The two pins of the elastic pin protrude outside the upper pipe body, and the lower pipe body slides on the step with elastic sliding properties. The pin extends into any set of locking holes for locking; the end of the upper tube includes a straight section and an arc section. When the upper tube rotates, the straight section abuts against the back of the spring plate to form a limit; or the locking structure includes several sets of opposite locking holes on the lower tube. Each locking hole is equipped with a limit nut, and each thread of the limit nut is connected to a limit screw. The limit screw extends into the locking hole and limits the movement of the steel tube after it has expanded or contracted; the bottom of the U-shaped frame is equipped with a support screw or a support pad, and a soft warning pad is fitted at the telescopic structure.

3. The football training rebounder board of claim 1, wherein, The elastic pin includes a V-shaped spring and two pins disposed on the V-shaped spring. The V-shaped spring is located inside the support frame, and the two pins extend outside the support frame; or the elastic pin includes a spring and two stepped pins, with the spring sleeved on the pins and the two pins extending outside the support frame.

4. The football training rebounder board of claim 1, wherein, The end of the flexible pin is a spherical body, and the length of the spherical body is greater than or equal to the depth of the pin hole.

5. The football training rebounder board of claim 1, wherein, There are two mounting bases, which are symmetrically arranged on the back of the spring plate. The mounting bases are flat-bottomed U-shaped structures with openings that serve as swing grooves.

6. The football training rebounder board of claim 5, wherein, The mounting base is also equipped with a horizontal bolt to resist the force when the support frame rotates to the maximum angle. The bolt is a hexagonal bolt or a square bolt and is locked with a nut. Alternatively, two limiting plates are provided at the gap of the mounting base to resist the force when the support frame rotates to the maximum angle. The limiting plates are formed by the flange of the opening on the side wall of the mounting base or by the plate set on the side wall or bottom of the swing groove.

7. The football training rebounder board of claim 1, wherein, The back of the rebound plate has a sliding hole, in which an L-shaped pin for inserting into the ground is slidably installed. The bottom end of the pin has a conical structure. The bottom of the rebound plate has an embedding groove, in which a support member for contacting the ground is installed. The support member is a support screw, a support boss, or a support pad. One side of the rebound plate is detachably equipped with a walking wheel for dragging during transportation.

8. The football training rebounder board of claim 1, wherein, The rebound board is one of the following: high-strength molded board, wood board, high-strength extruded board, or high-strength blow-molded board.

9. The football training rebounder board of claim 8, wherein, The rebound plate is a high-strength blow-molded plate or a high-strength extruded plate with an internal cavity. Its back side has several concave reinforcing grooves, which form a reinforcing platform in the cavity after being concave. The rebound plate has an injection hole that communicates with the cavity and a plug is provided at the injection hole. The cavity is filled with sand or water for weight increase.

10. The football training rebound plate according to claim 1, characterized in that, The back of the spring plate has mounting grooves on the left and right sides. The mounting grooves contain mounting strips that are fixed by screws. The mounting strips extend out of the mounting grooves so that the two spring plates can be used together.
