In the above basketball training aid device, the dummy main body 1 , the two movable arms 2 and the sliding bottom bracket 4 simulate the action of the defensive player swinging his arms up and down and moving left and right in basketball, with a high degree of action restoration.

Specifically, the special-shaped rotating block 8 is oval or water drop-shaped. Since the distance between the outer edge of the ellipse or the droplet shape and the center position changes with the rotation of the central axis, based on this property, the movable arm 2 in contact with it is driven to swing.

Example 2

In this embodiment, the base structure is described in detail on the basis of Embodiment 1.

Specifically, as shown in FIG. 2 and FIG. 3 , the base 5 includes a base body 5-1 and a linear drive mechanism disposed on the base body 5-1, and the sliding base 4 is driven by the linear drive The mechanism is driven to move linearly. The linear drive mechanism drives the sliding bottom bracket 4 to move linearly, simulating the actions of defenders.

The linear drive mechanism includes a lead screw 5-2 rotatably connected to the middle of the base body 5-1 through a bearing, a second motor 5-4 for driving the lead screw 5-2 to rotate, and a lead screw 5-4. 5-2 Engage the connected lead screw nut 9 , and the sliding bottom bracket 4 is fixed on the lead screw nut 9 .

Two sliding rails 5-3 are fixed on both sides of the lead screw 5-2 on the seat body 5-1, and two sliding blocks 10 are fixedly connected to the bottom of the sliding bottom bracket 4 at corresponding positions. The sliders 10 are respectively slidably connected with the corresponding slide rails 5-3 and slide on the two slide rails 5-3. The sliding rails 5-3 and the sliding block 10 are arranged to improve the stability of the sliding bottom bracket 4, prevent the sliding bottom bracket 4 from falling backward after being hit by a basketball, and at the same time make the sliding bottom bracket 4 move along the chute.

In order to facilitate the use and retraction of the training aid, a universal wheel 11 is fixed under the base 5 , and the number of the universal wheel 11 is 4-8.

Example 3

This embodiment introduces its preferred structure on the basis of Embodiment 1.

In order to better ensure the effective connection between the special-shaped rotating block 8 and the side of the movable arm 2 , the side of the special-shaped rotating block 8 is provided with a groove 13 , and the edge of the movable arm 2 is located in the groove 13 . The movable arm 2 is a sheet-like structure, and its side edge slides in the groove 13 to prevent the movable arm 2 from moving back and forth away from the special-shaped rotating block 8 and unable to swing.

In order to prevent the movable arm 2 from swinging over the vertical direction and toppling to the opposite side, a limit block 12 for defining the two movable arms 2 is provided in the middle of the dummy main body 1 .

The support rod 3 includes a sleeve 3-1 and an inner rod 3-2 nested in the sleeve 3-1, the dummy body 1 is fixed on the top of the inner rod 3-2, and the The bottom of the sleeve 3-1 is fixed on the sliding bottom bracket 4, and the bottom of the inner rod 3-2 is fixed in the sleeve 3-1 by bolts 14. The inner rod 3-2 is provided with a plurality of through holes (not shown in the figure), and the sleeve 3-1 is also provided with a through hole of the same size (not shown in the figure). The height of the rod 3-2 is aligned with the through hole of the sleeve 3-1, and the bolt 14 is inserted to fix it. The height-adjustable support bar 3 can adapt to trainers of different heights, while simulating defenders of different heights.

In order to facilitate height adjustment, a spring (not shown in the figure) is placed inside the sleeve 3-1, the bottom of the spring is in contact with the bottom of the sleeve 3-1, and the top of the spring is in contact with the bottom of the sleeve 3-1. The flanges outside the bottom of the inner rod 3-2 abut against each other. Under the action of the spring, the inner rod 3-2 is subjected to upward elastic force, which can reduce the force required to lift the inner rod 3-2 and facilitate upward adjustment. During downward adjustment, the gravity of the inner rod 3-2 and its connected dummy body 1 partially offsets the elastic force of the spring, preventing rapid falling under the action of gravity.

For ease of description, spatially relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to describe how one element or feature shown in the figures is relative to another element or feature. relation. It should be understood that, in addition to the orientation shown in the figures, spatial terms are intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both upper and lower positions. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative references used herein interpreted accordingly.

Moreover, relational terms such as "first" and "second" etc. are only used to distinguish one element from another having the same name and do not necessarily require or imply any such actual existence between those elements relationship or order.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications can be made without departing from the principles of the present invention. Improvement and modification should also be regarded as the protection scope of the present invention.
