DETAILED DESCRIPTION

[0018] In order to make those skilled in the art better understand the technical scheme, the utility model is described in detail below in conjunction with examples, and the description in this part is only exemplary and explanatory, and should not have any limit on the protection scope of the utility model.

[0019] As Figures 1-4As shown, the specific solution of this embodiment is as follows: a baseball throwing trainer includes opposing adjustment tubes 3, the height of which is adjustable; the lower ends of the opposing adjustment tubes 3 are respectively connected to the front base 1 and the rear base 2; a crossbar 4 is provided between the adjustment tubes 3, and a throwing assembly 5 is slidably provided at the upper end of the crossbar 4. The throwing assembly 5 includes a support plate 52, the lower end of which is mounted on a sliding block 54 via a screw 53, the upper end of which is slidably mounted on the crossbar 4, a hook 51 is provided at the front end of the sliding block 54, an elastic band 7 is provided on the hook 51, the other end of the elastic band 7 is provided at the top end of the adjustment tube 3, and a limiting component 100 is provided on the hook 51 to prevent the elastic band 7 from running out.

[0020] like Figure 1 As shown, in a preferred embodiment, the adjusting tube 3 is composed of multiple sections, including a lower tube with an upper tube inserted inside it. The upper tube has multiple through holes, and the lower tube has positioning holes for inserting a pull pin 9 to adjust the length and then position it. Through the cooperation of the through holes, positioning holes, and pull pin 9, rapid and stable height adjustment is achieved, making operation simple and the structure reliable.

[0021] like Figures 1-2 As shown, in a preferred embodiment, the front base 1 and the rear base 2 are respectively provided with a round tube sleeve 10 at both ends to enhance the contact area and stability between the front base 1 and the rear base 2 and the ground.

[0022] like Figure 1 As shown, in a preferred embodiment of the above, the support plate 52 is configured as an L-shape and is used to step on the non-weight-bearing foot during training.

[0023] like Figure 1 As shown, in a preferred embodiment, the elastic band 7 is inserted through the top of the adjusting tube 3 and then locked with bolts to prevent it from loosening during use and to ensure training safety.

[0024] like Figure 1 As shown, in a preferred embodiment, the sliding block 54 is configured with a U-shaped structure. The upper and lower ends of the sliding block 54 span the crossbar 4 via pulley bearings 6 and screws 8, achieving smooth sliding, reducing friction, and improving the smoothness of movement and service life. The entire throwing assembly 5 slides smoothly backward along the crossbar 4 under the action of the sliding block 54 and pulley bearings 6.

[0025] like Figures 3-4As shown, as the preferred mode of the above embodiment, the limiting assembly 100 includes a limiting block 12, the limiting block 12 is connected with the moving block 13, the side end of the moving block 13 is connected with the spring 14, the spring 14 is arranged at one end of the sliding block 54, the moving and limiting are loosened or compressed by the spring 14, the elastic band 7 is prevented from falling off from the hook body 51 when rebounding sharply, and the training safety is guaranteed.

[0026] The two ends of the crossbar 4 are provided with inner plugs 11 at the upper ends of the adjusting pipes 3.

[0027] During training, the trainer steps on the front base 1 or the rear base 2, and completes the throwing action by the inertia of the elastic band 7, the connecting throwing assembly 5 can flexibly adjust the tension of the elastic band, and meets different training requirements.

[0028] The trainer first fixes the equipment main body, adjusts the height of the adjusting pipe 3 to a suitable height, installs the elastic band 7, and non-tightly connects the elastic band 7 with the hook body 51, and then can start training. During training, the trainer independently places the center of gravity on the two sides of the higher end of the equipment according to the habit, bends the knee of the non-center of gravity side, and lightly steps the sole on the supporting plate 52, stabilizes the center of gravity, and then drives the supporting plate 52 to make a stepping and stretching action in the direction of the extension crossbar 4 through the sliding block 54. At this time, the elastic band 7 makes the supporting plate 52 become a resistance device due to the material characteristics, so as to achieve the training purpose, and the resistance changes with the change of the elastic modulus and the stretching distance of the elastic band 7. The training purposes are two: one is to increase the explosive force of the starting foot of the training runner; the other is to improve the fluency of the training runner in the conversion of the throwing running position, and to improve the proficiency.
