Description

Technical Field

[0001] The utility model relates to the technical field of tennis ball serving machines, in particular to an up and down angle swing adjustment mechanism for a tennis ball serving machine. Background Art

[0002] A tennis ball machine is a device designed to simulate a tennis serve, primarily used for tennis training and practice. It automatically serves the ball and can adjust the speed, spin, and interval of the serve, allowing players to practice repeatedly and improve their serving, receiving, and hitting skills.

[0003] The working principle of the tennis ball machine is mainly to squeeze the tennis ball and shoot it out through the relative rotation of two wheels. These two wheels are driven by a motor to rotate rapidly, and the different rotation speeds can produce topspin or backspin. This design allows the tennis ball machine to simulate the action of a real serve without damaging the tennis ball.

[0004] Existing tennis ball serving machines require an up and down swinging structure when in use, so that the up and down swinging structure drives the serving wheel to adjust the angle up and down, so that tennis balls of different heights can be served, which is convenient for practice. However, the up and down swinging structure of traditional tennis ball serving machines is relatively complex, and the manufacturing and maintenance costs are high, which increases the operating costs of the court and reduces the overall practicality. Therefore, the utility model proposes a simplified structure of the serving machine up and down angle swing adjustment mechanism. Utility Model Content

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] See also Figure 1-3 The utility model provides an embodiment of a ball machine up and down angle swing adjustment mechanism, comprising a lower base plate 1, a support plate 2 is fixedly mounted on the upper surface of the lower base plate 1, and the support plate 2 and the lower base plate 1 are arranged perpendicular to each other;

[0020] A swing shaft 3 is rotatably mounted above the support plate 2 through a bearing, a serving swing frame 4 is fixedly mounted on the top of the swing shaft 3, a passive gear 7 is fixedly mounted on one side of the serving swing frame 4, a driving motor 5 is fixedly mounted on the outer wall of one side of the support plate 2 through bolts, a driving gear 6 is fixedly mounted on the output shaft of the driving motor 5, and the driving gear 6 is meshed with the passive gear 7;

[0021] According to the above structure, when it is necessary to swing and adjust the serving angle of the serving swing frame 4, the driving motor 5 can be used. When the driving motor 5 is working, it drives the top driving gear 6 to rotate through the output shaft. When the driving gear 6 rotates, it synchronously drives the side driven gear 7 to rotate. During the rotation of the driven gear 7, the serving swing frame 4 will swing up and down with the swing shaft 3 as the center.

[0022] In actual use, the up and down swinging direction and the swinging angle of the serving swing frame 4 can be effectively controlled by controlling the rotation direction and the rotation angle of the driving motor 5, which has a better use effect.

[0023] In this embodiment, in order to ensure normal serving operation, serving wheels 8 are installed at the upper and lower ends of the serving swing frame 4 through bearings and rotating shafts;

[0024] The serving wheel 8 can be connected to the output shaft of the serving motor during actual use, so that the serving motor drives the serving wheel 8 to rotate relative to the serving motor, thereby ensuring normal tennis serving operation.

[0025] Working principle: When the utility model is in use, the lower base plate 1 is provided to install the entire mechanism in the working area of ​​the tennis ball machine, thereby completing normal installation and use;

[0026] When it is necessary to swing and adjust the serving angle of the serving swing frame 4 up and down, the driving motor 5 can be used. When the driving motor 5 is working, it will drive the top driving gear 6 to rotate through the output shaft. When the driving gear 6 rotates, it will synchronously drive the side passive gear 7 to rotate. During the rotation of the passive gear 7, the serving swing frame 4 will swing up and down with the swing shaft 3 as the center, thereby completing the up and down adjustment of the serving angles of the two serving wheels 8 through the angle adjustment of the serving swing frame 4.

[0027] In actual use, by controlling the rotation direction and rotation angle of the driving motor 5, the up and down swing direction and swing angle of the serving swing frame 4 can be effectively controlled, which has a better use effect.

[0028] For example: When you need to adjust the up and down direction of the ball, refer to the instructions. Figure 1 As a reference, when the driving motor 5 drives the driving gear 6 to rotate clockwise, the serving direction of the serving swing frame 4 is adjusted from bottom to top, and when the driving motor 5 rotates counterclockwise, the serving swing frame 4 is adjusted from top to bottom. In this way, the up and down swing adjustment work can be completed by controlling the driving motor 5 to rotate forward and reverse.

[0029] The swing angle can be adjusted up and down by controlling the rotation angle of the driving motor 5 to freely adjust the swing angle.

[0030] In summary, the ball serving machine of the utility model has an up and down angle swing adjustment mechanism, which can effectively swing the serving angle and serving direction of the ball serving machine up and down by controlling the rotation direction and rotation angle of the motor at the same time. It is easy to use, and the overall structure is simple and compact, easy to use, and has low manufacturing and maintenance costs, which effectively reduces the initial purchase and later use costs and has better practicality.

[0031] Moreover, the utility model adopts a single motor to drive the serving swing frame to swing back and forth up and down within a certain angle range, thereby having the swing adjustment characteristics of single motor drive. The single motor drive can effectively reduce the usage of the power structure, thereby effectively reducing the power loss of the mechanism, having the actual use effect of energy saving, effectively saving electricity resources, reducing the use cost, and at the same time being easy to install, the structure is easy to use, and is suitable for promotion and use.
