Description

Technical Field

[0001] The present invention relates to the technical field of basketball boards, and particularly relates to a basketball board that can project, play, and replay. Background Art

[0002] Basketball has the characteristics of being easy to learn and having low requirements for venue construction, and has the advantages of improving reaction ability, decision-making ability, and observation ability of people. As a result, basketball sports have been vigorously promoted in society, and basketball tools have become diversified. Some manufacturers print advertisements on basketball boards, making basketball boards commercially valuable. In order to facilitate the switching of the content of the advertisements on the basketball boards, basketball boards with screens have emerged. Such basketball boards can switch the display content at any time and can display game information.

[0003] However, for the existing basketball boards with screens currently, while facilitating the display of advertisements and game information, during basketball games, the basketball board body is frequently impacted by basketballs. When the basketball board is impacted, the basketball board vibrates violently, which is likely to damage the screen on the basketball board and affect the service life of the screen. At the same time, setting an electronic display screen on the basketball board will increase the weight of the basketball board, require an increase in the quality of the basketball hoop, increase the manufacturing cost of the basketball hoop, and the installation requirements of the basketball hoop will also increase accordingly, which is not conducive to achieving wide application.

[0014] Beneficial effects

[0015] 1. In the present invention, a projection device is arranged on the basketball board, and the required picture can be projected on the basketball board main body through the projection device, so as to achieve the effects of advertisement promotion and beauty. Compared with the traditional basketball board with a display screen, the weight of the basketball board is greatly reduced, the load-bearing burden of the basketball stand is reduced, and the problems that the basketball board with a display screen is too heavy and the manufacturing standard of the basketball stand is relatively high, increasing the manufacturing cost of the basketball stand are solved, making the basketball stand with a display function more conducive to wide application.

[0016] 2. In the projection device of the present invention, the hidden setting is realized by controlling the telescopic movement of the threaded push cylinder to switch the movable support frame between the hidden state and the exposed state. During the basketball game of the athlete, the hidden projector is hidden inside the through groove of the plate body by the contraction of the movable support frame. When the basketball hits the main body of the backboard or the movable support frame, it will not directly hit the hidden projector, effectively reducing the probability of damage to the hidden projector caused by impact and extending the service life of the hidden projector.

[0017] 3. In the present invention, a projection screen plate is provided. During the basketball game of the athlete, the projection screen plate fits on the surface of the upper projection groove of the main body of the backboard. The curtain on the projection screen plate fits with the curtain on the outer surface of the upper projection groove and is in a folded state. At the same time, the projection screen plate is completely located inside the upper projection groove, making the front surface of the main body of the backboard in a flat state, which will not affect the basketball movement. When the picture is projected, during the process of pushing the synchronous push rod and the movable support frame forward through the threaded push cylinder, the movable support frame moves out from the front of the through groove of the plate body. At the same time, the active rack on the frame and the active roller form a gear-rack transmission, driving the lower driving shaft to rotate. The lower driving shaft drives the upper driving shaft above to rotate through the transmission of the longitudinal transmission shaft. Through the meshing connection between the flipping driving wheel and the screen plate driven rotating wheel, the projection screen plate is driven to flip downward, so that the projection screen plate flips 180 degrees. The outer surface of the projection screen plate fits with the lower side of the front surface of the main body of the backboard, and the surface of the projection screen plate and the upper projection groove with the curtain faces forward. The hidden projector projects the image on the curtain for display. Compared with the traditional way of directly projecting on the surface of the backboard with a basketball board equipped with a projection device, it has a better projection effect.
