[0002] A barometric pressure testing device typically consists of a dial, a needle, and a connecting component. The dial has scales that display the barometric pressure value visually. The needle is inserted into the inflation hole of the ball, and the connecting component connects the two. Its advantages are simple structure, relatively low price, and intuitive reading. Its disadvantages are that the accuracy may be relatively low, and the pointer may deviate due to collisions or other reasons.

A ball needle is located at the center of the ball holder, and a pressure sensor is attached to the tip of the needle. The base houses a data processing system, and a display screen and reset button are located on the side. In use, the ball is placed in the groove of the holder, the ball needle is inserted into the inflation port, and the pressure sensor transmits the air pressure to the data processing system. The processed data is then displayed on the screen. Additionally, an electric air pump can be installed on the base for convenient inflation of balls with low pressure. This device is suitable for use in places with a large number of balls, such as schools.
[0004] The air pressure detection device used for ball training has the following defects: it lacks a preset function; novice users or those who do not understand air pressure filling are prone to misremembering the standard value, leading to misjudgment; and it results in a large difference from the standard air pressure (such as 0.6-0.7 bar for basketballs and 0.8-1.1 bar for soccer balls). Excessive or insufficient air pressure can make the ball too hard or too soft, causing abnormal ball flight trajectory and deviation from previous training, thus affecting training effectiveness. Therefore, a new air pressure detection device for ball training is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-3This utility model provides an embodiment of an air pressure detection device for ball sports training, comprising an air pressure connector 1 and an air injection port 2. The air injection port 2 is fixedly connected to the inner right side wall of the air pressure connector 1. The air injection port 2 can be connected to an air injection device for replenishment when insufficient air pressure is detected. A connector 3 is fixedly connected to the top outer wall of the air pressure connector 1. An adjustment mechanism 4 and an auxiliary mechanism 5 are provided on the air pressure connector 1. The adjustment mechanism 4 includes a threaded cylinder 41, which is fixedly connected to the top outer wall of the air pressure connector 1. A female opening 42 is sleeved on the side outer wall of the connector 3. The side of the threaded cylinder 41... The outer wall of the device is threaded with a mounting cylinder 43. The top outer wall of the mounting cylinder 43 is rotatably connected to a bearing disk 44. The top outer wall of the bearing disk 44 is fixedly connected to a pressure display 45. The front outer wall of the pressure display 45 is fixedly connected to a pressure pointer 46. The front outer wall of the pressure display 45 has a mounting groove 47. The front inner wall of the mounting groove 47 is snapped with a scale magnetic plate 49. The scale magnetic plate 49 has preset optimal air pressure scales for different types of balls. In conjunction with the pressure pointer 46, it allows users to quickly determine whether the current air pressure meets the standard. The snap-fit method makes it convenient to change the magnetic plate with different scales according to the type of ball.
[0024] Reference Figures 2-4 The female port 42 is fixedly connected to the bottom outer wall of the barometric pressure display 45. A silicone pad is fixedly connected to the side outer wall of the mounting cylinder 43. The silicone pad increases the friction between the hand and the mounting cylinder 43, making it easier for the user to rotate the mounting cylinder 43 to adjust the height. At the same time, the soft silicone material improves the grip comfort and prevents the hand from slipping. An adjustment plate 410 is slidably connected to the front inner wall of the barometric pressure display 45. A limit plate 411 is fixedly connected to the left outer wall of the adjustment plate 410. There are two adjustment plates 410, and the two adjustment plates 410 are respectively connected to each other. Symmetrical, a compression spring 412 is fixedly connected to the right outer wall of the adjustment plate 410, and a frosted pad is fixedly connected to the side outer wall of the adjustment plate 410. The frosted pad increases the friction between the adjustment plate 410 and the inner wall of the air pressure display 45, preventing the adjustment plate 410 from sliding on its own when not in operation, and ensuring the stable fixing effect of the limit plate 411 on the magnetic plate. The two ends of the compression spring 412 are fixedly connected to the side outer walls of the two adjustment plates 410 respectively, and the limit plate 411 is snapped into the left and right inner walls of the scale magnetic plate 49.
[0025] Reference Figures 3-4The auxiliary mechanism 5 includes a storage slot 51, which is fixedly connected to the left outer wall of the air pressure connector 1. The storage slot 51 is used to store the scale magnet plate 52 to prevent it from being lost when not in use, while maintaining the overall neatness of the device and making it easy to carry and store. The scale magnet plate 52 is slidably connected to the top inner wall of the storage slot 51. The scale magnet plate 52 contacts the front outer wall of the scale magnetic plate 49. The scale magnet plate 52 is magnetically attached to the scale magnetic plate 49 and can be adjusted in position according to the specific air pressure requirements of different balls to mark the optimal air pressure point more precisely and improve detection accuracy. A frosted sleeve 53 is attached to the side outer wall of the air pressure connector 1. The frosted sleeve 53 increases the friction between the hand and the air pressure connector 1, making it easier for the user to hold the device and insert the air pressure connector 1 into the ball inflation port, avoiding slippage that could lead to insertion deviation or the device falling, and improving operational safety.
[0026] Working principle: By inserting the air pressure connector 1 into the air inlet of a basketball or soccer ball, the data detected by the air pressure connector 1 is transmitted through the connector 3 and then through the female port 42 to the air pressure display 45 for display. This causes the air pressure pointer 46 to rotate. By observing the preset position of the scale magnetic plate 49, the optimal air pressure is indicated. Simultaneously, when testing different types of balls, the scale magnetic plate 52 is pulled out of the storage slot 51, and then the small scale plate on the scale magnetic plate 52 is removed. Attach it to the scale magnetic plate 49 and adjust the pressure measurement position. This will allow multiple users to clearly know the optimal position for inflation, avoiding excessive or insufficient air pressure. If the scale magnetic plate 49 becomes worn or unclear, or if the scale does not conform to the standard of other spheres, pull the adjustment plate 410 to move the limit plate 411. The limit plate 411 will move and separate from the inner walls on both sides of the scale magnetic plate 49. Then, remove the scale magnetic plate 49 from the mounting slot 47 and replace it with a new scale magnetic plate 49.
[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
