Description

Technical Field

[0001] This utility model relates to the field of basketball inflation technology, specifically to a basketball inflation device that can inflate quickly. Background Technology

[0002] A basketball inflation device is a tool used to add air to a basketball to maintain its elasticity and performance. The electric air pump has a built-in motor that drives the piston. It can be connected to a power source or battery and has a pressure gauge. It inflates quickly and effortlessly, making it suitable for high-frequency use. Basketballs may leak air after long-term use or storage. The inflation device can restore its elasticity and ensure the feel of shooting and dribbling. The proper air pressure for a basketball, about 7-9 psi, can reduce ball deformation and prevent premature damage to the inner bladder or outer skin.

[0003] Existing basketball inflation devices require manual alignment to fix the inflation port. However, manual alignment of the inflation port can lead to errors, causing the inflation needle to be inserted in the wrong direction. When the needle is inserted at an angle, it rubs against the rubber sealing ring on the inner wall of the air hole, resulting in scratches or deformation on the surface of the sealing ring and a decrease in air retention performance. Basketballs need to be inflated weekly or even after every game. Over time, this can cause the sealing ring to break, resulting in permanent air leakage from the air hole and rendering the basketball unusable. Utility Model Content

[0004] This invention provides a basketball inflation device that can inflate quickly, which has the advantages of rapid and stable inflation of basketballs, thus solving the problem of cumbersome operation of limiting and fixing the inflation port of basketballs.

[0005] To achieve rapid and stable inflation of a basketball, this utility model provides the following technical solution: a basketball inflation device for rapid inflation, comprising a basketball inflator, wherein the basketball inflator has an internal placement groove, and a limiting component is installed inside the basketball inflator. Four locking blocks are installed on the outer surface of the limiting component, and each of the four locking blocks has a limiting locking assembly installed on its outer surface. Each limiting locking assembly includes two ball heads and an arc block. Two ball heads are installed on the outer surface of each locking block, and an arc block is installed on its outer surface. A movable groove is formed inside the arc block, and springs are evenly distributed along the inner wall of the movable groove. A limiting arc plate is installed on the outer surface of several springs, and the outer surface of the limiting arc plate is in movable contact with the inner wall of the movable groove.

[0006] As a preferred embodiment of this utility model, a motor is mounted on the outer surface of the basketball inflator, and a rotating shaft is mounted on the outer surface of the motor output end.

[0007] As a preferred embodiment of this utility model, a main bevel gear is mounted on the outer surface of the rotating shaft, and a turntable is movably mounted inside the basketball inflator.

[0008] As a preferred embodiment of this utility model, a driven bevel gear is installed on the bottom surface of the turntable, and the outer surface of the main bevel gear meshes with the outer surface of the driven bevel gear.

[0009] As a preferred embodiment of this utility model, a progressive threaded strip is installed on the top surface of the turntable, and a progressive threaded groove is formed on the bottom surface of the locking block. The inner wall of the progressive threaded groove is in movable contact with the outer surface of the progressive threaded strip.

[0010] As a preferred embodiment of this utility model, the inner surface of the basketball inflator is equipped with two limiting slide rails, and the top surface of the basketball inflator is equipped with a hydraulic rod.

[0011] As a preferred embodiment of this utility model, a limiting slider is installed on one end surface of the hydraulic rod output end, the outer surface of the limiting slider meshes with the outer surfaces of the two limiting slide rails, and an air injection needle is installed on the outer surface of the limiting slider.

[0012] Compared with the prior art, this utility model provides a basketball inflation device that can be quickly inflated, which has the following beneficial effects:

[0013] This rapid-inflation basketball inflation device uses four locking blocks that move radially and synchronously towards the center. Two ball heads at the end of each block apply uniform pressure to the basketball surface. A limiting arc plate, under the pressure of the locking blocks, retracts along the movable groove, compressing the internal spring and forming an elastic buffer to prevent excessive compression and damage to the basketball. This ensures the basketball is stably fixed within the placement groove. A hydraulic rod then drives a limiting slider to move stably up and down outside two limiting rails, allowing the inflation needle to be inserted into the air hole stably, quickly, and accurately, thus achieving rapid inflation. Automatic centering is achieved through the geometric matching of the basketball's grooves and the limiting arc plate, eliminating the need for sensors for initial positioning and removing the lateral force during needle insertion. Operators only need to perform two actions: rotation and start, significantly shortening the inflation cycle and enabling rapid inflation of the basketball. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-6This utility model discloses a basketball inflation device that can be quickly inflated, including a basketball inflator 1. The basketball inflator 1 has an internal placement groove 19. A limiting component is installed inside the basketball inflator 1. Four locking blocks 8 are installed on the outer surface of the limiting component. Each of the four locking blocks 8 has a limiting engagement component on its outer surface. The limiting engagement component includes two ball heads 14 and an arc block 10. The outer surface of each locking block 8 has two ball heads 14 and an arc block 10. The arc block 10 has a movable groove 11 inside. Springs 12 are evenly distributed and installed on the inner wall of the movable groove 11. A limiting arc plate 13 is installed on the outer surface of several springs 12. The outer surface of the limiting arc plate 13 is in contact with the inner wall of the movable groove 11. Four locking blocks 8 move radially and synchronously toward the center. The two ball heads 14 at the end of each locking block 8 apply uniform pressure to the surface of the basketball. Under the pressure of the locking blocks 8, the limiting arc plate 13 retracts along the movable groove 11, compressing the internal springs 12 and forming an elastic buffer. The system uses a combination of hydraulic rod 15 and hydraulic rod 16 to prevent excessive pressure that could damage the basketball, thus ensuring the basketball is stably fixed within the placement groove 19. The hydraulic rod 15 then drives the limiting slider 17 to move stably and quickly outside the two limiting slide rails 16, allowing the inflation needle 18 to be inserted into the air hole stably, quickly, and accurately, thus achieving rapid inflation of the basketball. Automatic centering is achieved by utilizing the geometric matching between the basketball's grooves and the limiting arc plate 13, completing initial positioning without the need for sensors. Furthermore, the four locking blocks 8 move centripetally at the same speed, and the eight contact points form a ring-shaped, evenly distributed load, preventing single-point overpressure that could deform the basketball. The spring 12 buffer mechanism further protects the ball's surface. The vertical lifting combination of the two limiting slide rails 16 and the hydraulic rod 15 eliminates the lateral force during the insertion of the inflation needle 18, ensuring air hole alignment accuracy even during manual operation. From rotational pre-positioning to locking of the locking blocks 8 and insertion of the inflation needle, all actions are completed in one go through mechanical linkage. The operator only needs to perform two actions: rotation and start, significantly shortening the inflation cycle and thus rapidly inflating the basketball.

[0023] A motor 2 is mounted on the outer surface of a basketball inflator 1. A rotating shaft 3 is mounted on the outer surface of the output end of the motor 2. A main bevel gear 4 is mounted on the outer surface of the rotating shaft 3. A turntable 6 is movably mounted inside the basketball inflator 1. A driven bevel gear 5 is mounted on the bottom surface of the turntable 6. The outer surfaces of the main bevel gear 4 and the driven bevel gear 5 mesh with each other. A progressive threaded bar 7 is mounted on the top surface of the turntable 6. A progressive threaded groove 9 is opened on the bottom surface of the locking block 8. The inner wall of the progressive threaded groove 9 is in contact with the outer surface of the progressive threaded bar 7. The motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the main bevel gear 4 to rotate. The outer surface of the main bevel gear 4 meshes with the outer surface of the driven bevel gear 5, thereby causing the driven bevel gear 5 to drive the turntable 6 to rotate. The turntable 6 drives the progressive threaded bar 7 to rotate, and the outer surface of the progressive threaded bar 7 meshes with the inner wall of the progressive threaded groove 9, thereby causing the four locking blocks 8 to move synchronously in a straight line.

[0024] Two limiting slide rails 16 are installed on the inner surface of the basketball inflator 1. A hydraulic rod 15 is installed on the top surface of the basketball inflator 1. A limiting slider 17 is installed on one end of the output end of the hydraulic rod 15. The outer surface of the limiting slider 17 meshes with the outer surface of the two limiting slide rails 16. An air injection needle 18 is installed on the outer surface of the limiting slider 17. The hydraulic rod 15 drives the limiting slider 17 to move stably up and down outside the two limiting slide rails 16, so that the air injection needle 18 can be inserted into the air hole stably, quickly and accurately, thereby realizing the rapid inflation of the basketball.

[0025] The working principle and usage process of this utility model are as follows: When it is necessary to inflate a basketball, the basketball is placed in the placement groove 19. The operator rotates the basketball by hand, and the basketball rotates in the placement groove 19, so that the shape of the ball groove on the outside of the basketball matches the shape of the protrusion of the limiting arc plate 13, thereby limiting the basketball in the placement groove 19. When the four limiting arc plates 13 are in contact with the ball groove on the outside of the basketball, the basketball is limited. At this time, the inflation hole of the basketball corresponds to the air injection needle 18.

[0026] Meanwhile, motor 2 operates synchronously, driving rotating shaft 3 to rotate. Rotating shaft 3 drives main bevel gear 4 to rotate. The outer surface of main bevel gear 4 meshes with the outer surface of driven bevel gear 5, causing driven bevel gear 5 to drive turntable 6 to rotate. Turntable 6 drives progressive threaded bar 7 to rotate. The outer surface of progressive threaded bar 7 meshes with the inner wall of progressive threaded groove 9, causing four locking blocks 8 to move synchronously in a straight line. This causes eight ball heads 14 to limit and compress the basketball, while limiting arc plate 13 compresses spring 12 within movable groove 11. The four locking blocks 8 move radially synchronously towards the center. The two ball heads 14 at the end of each locking block 8 apply uniform pressure to the surface of the basketball. Under the compression of the locking blocks 8, limiting arc plate 13 retracts along movable groove 11, compressing the internal spring 12 to form an elastic buffer, preventing excessive compression and damage to the basketball, thus stably fixing the basketball in the placement groove. Within 19, the hydraulic rod 15 drives the limiting slider 17 to move stably up and down outside the two limiting slide rails 16, thereby allowing the inflation needle 18 to be inserted into the air hole stably, quickly and accurately, thus realizing the rapid inflation of the basketball. The basketball's own groove and the geometric matching of the limiting arc plate 13 achieve automatic centering, and the initial positioning can be completed without sensors. Moreover, the four locking blocks 8 move centripetally at the same speed, and the eight contact points form a ring-shaped uniform load, avoiding single-point overpressure that could cause the basketball to deform. The spring 12 buffer mechanism further protects the surface of the ball. The vertical lifting combination of the two limiting slide rails 16 and the hydraulic rod 15 eliminates the lateral force when the inflation needle 18 is inserted. Even with manual operation, the air hole alignment accuracy can be guaranteed. From rotation pre-positioning to locking of the locking blocks 8 and insertion of the inflation needle, all actions are completed at once through mechanical linkage. The operator only needs to perform two actions: rotation and start, which significantly shortens the single inflation cycle and thus quickly inflates the basketball.
