Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

A basketball training auxiliary device, as shown in figure 1, comprises a dummy body 1, two movable arms 2 rotatably connected with the front part of the dummy body 1, a sliding bottom support 4 for supporting the dummy body 1 and a base 5 for providing driving force and balancing force for the sliding bottom support 4, the bottom of the dummy body 1 is fixed on the top of the sliding bottom support 4 through a support rod 3, each movable arm 2 is driven by a swinging device to swing, each swinging device comprises a first motor 6, a transmission shaft 7 fixed on an output shaft of the first motor 6 and a special-shaped rotating block 8 driven by the transmission shaft 7, the first motor 6 is fixed to the back of the dummy body 1, the transmission shaft 7 extends to the dummy body 1 through a through hole formed in the dummy body 1, the special-shaped rotating block 8 is positioned at the front part of the dummy body 1 and is fixed at the end part of the transmission shaft 7.

In the basketball training auxiliary device, the dummy body 1, the two movable arms 2 and the sliding bottom support 4 simulate the actions of a defender who swings the arms up and down and moves left and right in the basketball movement, and the action restoration degree is high.

Specifically, the special-shaped turning block 8 is in an oval shape or a drop shape. Because the distance between the outer edge of the oval or the drop shape and the central position changes along with the rotation of the central shaft, the movable arm 2 in contact with the central shaft is driven to swing due to the property.

Example 2

This embodiment describes the structure of the base in detail based on embodiment 1.

Specifically, as shown in fig. 2 and 3, the base 5 includes a base body 5-1 and a linear driving mechanism disposed on the base body 5-1, and the sliding shoe 4 is driven by the linear driving mechanism to move linearly. The linear driving mechanism drives the sliding bottom support 4 to move linearly, and the action of defensive personnel is simulated.

The linear driving mechanism comprises a screw rod 5-2 which is rotatably connected to the middle part of the base body 5-1 through a bearing, a second motor 5-4 which is used for driving the screw rod 5-2 to rotate, and a screw nut 9 which is in meshed connection with the screw rod 5-2, and the sliding bottom support 4 is fixed on the screw nut 9.

Two sliding rails 5-3 are fixed on the base body 5-1 at two sides of the screw 5-2, two sliding blocks 10 are fixedly connected at corresponding positions at the bottom of the sliding bottom support 4, and each sliding block 10 is respectively connected with the corresponding sliding rail 5-3 in a sliding manner and slides on the two sliding rails 5-3. The arrangement of the tracks 5-3 and the slides 10 is to improve the stability of the shoe 4, preventing it from falling backwards after being hit by a basketball, while allowing the shoe 4 to move along the runner.

In order to facilitate the use and the retraction of the training auxiliary device, universal wheels 11 are fixed below the base 5, and the number of the universal wheels 11 is 4-8.

Example 3

This embodiment is described based on embodiment 1, and its preferred structure is described.

In order to better ensure the effective connection between the special-shaped rotating block 8 and the side edge of the movable arm 2, a groove 13 is arranged on the side edge of the special-shaped rotating block 8, and the edge of the movable arm 2 is positioned in the groove 13. The movable arm 2 is of a sheet structure, and the side edge of the movable arm slides in the groove 13, so that the movable arm 2 is prevented from moving back and forth and being separated from the special-shaped rotating block 8 to be incapable of swinging.

In order to prevent the movable arms 2 from tilting to the opposite side after swinging in the vertical direction, the middle part of the dummy body 1 is provided with a limiting block 12 for limiting the two movable arms 2.

The support rod 3 comprises a sleeve 3-1 and an inner rod 3-2 nested in the sleeve 3-1, the dummy body 1 is fixed to the top of the inner rod 3-2, the bottom of the sleeve 3-1 is fixed to the sliding bottom support 4, and the bottom of the inner rod 3-2 is fixed to the sleeve 3-1 through a bolt 14. The inner rod 3-2 is provided with a plurality of through holes (not shown in the figure), the sleeve 3-1 is also provided with a through hole (not shown in the figure) with the same size, when the height is adjusted, the height of the inner rod 3-2 is adjusted, the through hole is aligned with the through hole of the sleeve 3-1, and the bolt 14 is inserted for fixing. The height-adjustable supporting rod 3 can adapt to trainers with different heights and simulate defensive personnel with different heights.

In order to adjust the height conveniently, a spring (not shown in the figure) is placed inside the sleeve 3-1, the bottom of the spring is abutted against the bottom of the sleeve 3-1, and the top of the spring is abutted against a flange formed outside the bottom of the inner rod 3-2. Under the action of the spring, the inner rod 3-2 is subjected to upward elastic force, so that the force required for lifting the inner rod 3-2 can be reduced, and upward adjustment is facilitated. When the inner rod 3-2 is adjusted downwards, the gravity of the inner rod 3-2 and the dummy body 1 connected with the inner rod partially offsets with the elastic force of the spring, so that the inner rod is prevented from falling rapidly under the action of the gravity.

Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. 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 an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Moreover, relational terms such as "first" and "second," and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
