Description

Technical Field

[0001] This utility model relates to the field of ball-serving equipment technology, specifically a table tennis ball-serving device. Background Technology

[0002] Table tennis, known as China's "national sport," is a popular ball sport worldwide. It includes offense, confrontation, and defense. When training, table tennis players need to use serving equipment to practice serving.

[0003] Most existing ball-serving devices only focus on launching the ping-pong ball, without considering the possibility of the ball getting stuck inside the device, preventing normal serving and affecting athletes' training. In related technologies, a motor-driven connecting rod rotates a scraper inside the ball-adding box to agitate the ping-pong ball, thus preventing it from getting stuck inside the serving device. However, in this technology, the landing point, speed, and spin of the ball served from a fixed point are always the same, lacking variation. This limits the diversity and practicality of training, and has certain limitations, making it inconvenient to use. Utility Model Content

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] When using it, first fix the position of the ball-serving box, then add ping-pong balls into the ball-adding box, then stand opposite the ball-serving box, turn on the ball-serving device, and start training.

[0032] In related technologies, a scraper is driven by a motor to rotate inside the ball box, stirring the ping-pong balls and preventing them from clogging inside the serving device. However, in this technology, the landing point, speed, and spin of the ball served by the serving machine are always the same, lacking variation. This limits the diversity and practicality of training, has certain limitations, and causes inconvenience in use.

[0033] To address some of the problems in the related technologies, this application provides a chili harvesting device. In use, simply insert the ball-serving box 11 into the mounting base 21, and installation is complete after hearing a "click." It is convenient and quick. At the same time, the height adjustment mechanism 23 located at the bottom of the mounting base 21 and the reciprocating mechanism 25 located at the bottom of the protective box 24 can adjust the height of the ball-serving box 11 or make the ball-serving box 11 reciprocate according to training needs, thereby enhancing the diversity of serves and improving training effectiveness.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] Combination Figures 1-4 This application provides a table tennis serving device, including: a serving box 11 with a ball-adding box 12 fixedly connected to its top; a serving port 13 fixedly connected to one end of the serving box 11; and an adjustment component 2 disposed below the serving box 11. The adjustment component 2 includes: a mounting base 21 disposed at the bottom of the serving box 11; a mounting mechanism 22 disposed inside the mounting base 21, and the mounting base 21 connected to the serving box 11 through the mounting mechanism 22; a height adjustment mechanism 23 disposed at the bottom of the mounting base 21; a protective box 24 disposed outside the height adjustment mechanism 23; a reciprocating mechanism 25 fixedly disposed at the bottom of the protective box 24; and an adjustment box 26 slidably connected to the outside of the protective box 24, and the reciprocating mechanism 25 connected to the adjustment box 26.

[0036] In use, first insert the ball box 11 downwards into the mounting base 21. When the ball box 11 moves to the bottom of the groove at the top of the mounting base 21, the spring 224 releases its elastic potential energy, pushing the side slider 222 to move the mounting block 221 to both sides of the mounting base 21, thus limiting the position of the ball box 11. During training, turn on the motor inside the ball box 11 to launch the ping-pong ball. Then, turn on the first motor 235 to drive the active bevel gear 234 to rotate, which in turn drives the driven bevel gear 233 and the threaded sleeve 232 to rotate together, thereby driving the adjusting rod 231 to move up and down, thus adjusting the height of the ball box 11. Turn on the second motor 253 to drive the half gear 252 to rotate, which in turn drives the rack disc 251 and the protective box 24 to move back and forth, thereby enhancing the diversity of serves and improving the training effect.

[0037] In some embodiments, the mounting mechanism 22 includes: a mounting block 221, slidably connected to both sides inside the mounting base 21, with grooves on both sides of the ball box 11, the size and shape of which are the same as those of the mounting block 221; a side slider 222, fixedly connected to both sides of the mounting block 221, and the side slider 222 is slidably connected to the interior of the mounting base 21; a guide rod 223, slidably connected to the interior of the side slider 222, and the guide rod 223 is fixedly connected to the interior of the mounting base 21; a spring 224, sleeved on the outside of the guide rod 223; and an unlocking plate 225, fixedly connected to the top of the mounting block 221, the unlocking plate 225 penetrating the top of the mounting base 21, and the unlocking plate 225 slidably connected to the top of the mounting base 21.

[0038] In use, as the ball box 11 slides downwards into the mounting base 21, the mounting block 221 is first pressed by both sides of the mounting base 21, which in turn drives the side slider 222 to slide along the guide rod 223, thereby compressing the spring 224. When the mounting block 221 reaches the grooves on both sides of the mounting base 21, the mounting base 21 no longer blocks the mounting block 221, and the spring 224 releases its elastic potential energy, thereby pushing the side slider 222 to move the mounting block 221 toward the groove, thus locking the mounting block 221 into the groove and limiting the ball box 11. When disassembling, simply pull the two unlocking plates 225 to pull the mounting block 221 out of the groove, and the ball box 11 can be easily taken out from the top of the mounting base 21, which is convenient and quick.

[0039] In some embodiments, the mounting blocks 221 are provided with inclined surfaces on their adjacent sides. The inclined surfaces are narrower at the top and wider at the bottom to ensure that the mounting blocks 221 can be pressed down during the downward movement of the ball box 11, which facilitates installation.

[0040] In some embodiments, the height adjustment mechanism 23 includes: an adjusting rod 231, fixedly connected to the center of the bottom of the mounting base 21, and the adjusting rod 231 has threads on its exterior; a threaded sleeve 232, threadedly connected to the exterior of the adjusting rod 231; a driven bevel gear 233, fixedly connected to the bottom of the threaded sleeve 232; a driving bevel gear 234, meshing with one side of the driven bevel gear 233; a primary motor 235, disposed on one side of the driving bevel gear 234, and the output end of the primary motor 235 is fixedly connected to one side of the driving bevel gear 234; and a telescopic rod 236, the top of which is fixedly connected to the four corners of the bottom of the mounting base 21, and the bottom of the telescopic rod 236 is fixedly connected to the interior of the protective box 24.

[0041] In use, start motor 235 to drive the drive bevel gear 234 to rotate. Since the driven bevel gear 233 and the drive bevel gear 234 are meshed, the top of the driven bevel gear 233 is fixedly connected to the threaded sleeve 232. The rotation of the drive bevel gear 234 will drive the threaded sleeve 232 to rotate together, thereby driving the adjusting rod 231 connected to the thread inside the threaded sleeve 232 to move up and down. The telescopic rods 236 at the four corners of the bottom of the mounting base 21 can ensure the stability of the up and down movement of the mounting base 21 and prevent the mounting base 21 from rotating and causing damage to the device.

[0042] In some embodiments, the reciprocating mechanism 25 includes: a rack 251 fixedly connected to the bottom of the protective box 24; a half gear 252 meshing with the inside of the rack 251; and a second motor 253 fixedly installed on the bottom of the adjusting box 26, with the output end of the second motor 253 fixedly connected to the bottom of the second motor 253.

[0043] When in use, turn on motor 253. Motor 253 drives half gear 252 to rotate. During the rotation of half gear 252, the meshing action between half gear 252 and rack 251 on one side will drive rack 251 to move. When half gear 252 rotates to the other side of rack 251, it will drive rack 251 to move along the opposite path, thereby realizing the reciprocating motion of rack 251.

[0044] In some embodiments, a fixing component 3 is provided on one side of the adjusting box 26; the fixing component 3 includes: a threaded rod 31, which is threadedly connected to one side of the adjusting box 26, and a concave groove is opened on one side of the adjusting box 26, and the threaded rod 31 is threadedly connected to the upper half of the concave groove; a pressure plate 32, which rotates at the bottom of the threaded rod 31, and the pressure plate 32 is slidably connected to the inside of the groove on one side of the adjusting box 26. When fixing, the concave groove is aligned with the plane to be installed and inserted, and then the threaded rod 31 is rotated, thereby driving the pressure plate 32 to move downward, and the installation is achieved by pressing the installation plane through the pressure plate 32.

[0045] In some embodiments, anti-slip pads are fixedly connected to the bottom of the pressure plate 32 and the groove on one side of the adjustment box 26 to prevent slipping.

[0046] In some embodiments, a limiting component 4 is provided between the protective box 24 and the reciprocating mechanism 25 and the adjusting box 26; the limiting component 4 includes: a limiting block 41, which is fixedly connected to both sides inside the adjusting box 26; and a limiting groove 42, which is opened on both sides of the protective box 24, and the width and height of the limiting groove 42 are equal to the width and height of the limiting block 41, thereby restricting the sliding of the protective box 24 inside the adjusting box 26 and preventing the protective box 24 from falling out of the adjusting box 26.
