Description

Technical Field

[0001] This utility model relates to the field of inflatable technology, and in particular to an inflatable device for easily fixing a basketball. Background Technology

[0002] Basketball is a hand-centric physical contact sport. The inflation device of a basketball mainly refers to the tool or equipment that can inflate the basketball. An inflated basketball has sufficient elasticity and rebound force, which makes it easier for players to control the height and direction of the ball's bounce, thereby better displaying their skills in the game. An uninflated basketball will appear soft and weak, unable to provide enough rebound force, affecting players' dribbling, shooting, and passing actions.

[0003] A search revealed that Chinese Patent CN213347679U discloses an inflation device for basketball production that facilitates the fixing of basketballs. Currently, most inflation devices for basketball production on the market are similar, but their operational efficiency varies greatly. The main issue is the lack of an effective and stable fixing mechanism when inflating the basketball. Furthermore, even those with fixing measures lack height adjustment functionality. Therefore, a sliding frame and a spherical tray are provided. These trays primarily serve to limit and fix the basketball. Since the basketball's outer contour is spherical, and spherical objects are prone to rolling and movement during operation, thus affecting operational efficiency, the semi-circular bowl-shaped spherical tray helps to fit and fix the basketball to the outside.

[0004] The aforementioned inflation device is convenient for securing the basketball during use. However, the device only uses a semi-circular bowl-shaped tray to limit the basketball, and it is not convenient to limit the sides of the basketball. This makes the limiting and fixing effect relatively weak. When external vibrations or impacts occur, the impact force affects the tray, causing the basketball to roll off the tray. This affects the stability during the inflation process and reduces the inflation efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an inflatable device for securing basketballs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inflation device for facilitating the fixing of a basketball, comprising an air pump, a mounting bracket fixedly connected to the lower surface of the air pump, a connecting rod fixedly connected to one side of the mounting bracket, a mounting box fixedly connected to one end of the connecting rod, a bidirectional lead screw rotatably connected inside the mounting box, a knob fixedly connected to one end of the bidirectional lead screw, and movable rods threadedly connected to both ends of the bidirectional lead screw, the two movable rods being slidably connected inside the mounting box, and a clamping assembly provided outside the movable rods.

[0007] As a further description of the above technical solution:

[0008] The clamping assembly includes an adjusting shell slidably connected to the outside of a moving rod. One end of the moving rod is fixedly connected to a stud, and a nut is threaded onto the outside of the stud. A fixing rod is fixedly connected to the upper surface of the adjusting shell. One end of the fixing rod is fixedly connected to a limiting plate. Two springs and two outer tubes are fixedly connected to one side of the limiting plate. The outer tubes are disposed inside the springs, and inner tubes are slidably connected inside the outer tubes. One end of each of the two inner tubes is fixedly connected to a fastening plate.

[0009] As a further description of the above technical solution:

[0010] The upper surface of the mounting box is fixedly connected to a placement shell, and both sides of the mounting frame are provided with fixing components. The fixing components include fixing plates, and the two fixing plates are respectively fixedly connected to both sides of the mounting frame.

[0011] As a further description of the above technical solution:

[0012] The upper surfaces of the two fixed plates and the connecting rod are rotatably connected with threaded tubes, and the upper surfaces of the two fixed plates and the connecting rod are provided with through grooves. The threaded tubes are threaded with screws, and the through grooves are slidably connected with limit rods.

[0013] As a further description of the above technical solution:

[0014] A connecting plate is fixedly connected to one end of the limiting rod and the screw, and a suction cup is fixedly connected to the lower surface of the connecting plate.

[0015] As a further description of the above technical solution:

[0016] Two of the threaded tubes are fixedly connected to the outside of small synchronous pulleys, while the other threaded tube is fixedly connected to the outside of two large synchronous pulleys.

[0017] As a further description of the above technical solution:

[0018] A knob is fixedly connected to the upper surface of one of the small synchronous pulleys, and a synchronous belt is provided between the small synchronous pulley and the large synchronous pulley.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model enhances the function of limiting and fixing the basketball in the inflation device by setting up the clamping component. It makes it easier to limit and fix the basketball after the bottom shell is used to support the basketball, and then limit the two sides of the basketball. This reduces the phenomenon that the basketball will roll out of the shell due to the influence of external vibration or impact, thus affecting the inflation stability. It helps to improve inflation efficiency and makes it easy to adjust the clamping height of the two sides of the clamping component according to the size and height of the basketball, improving the compatibility between the inflation device and basketballs of different sizes.

[0021] 2. By adding a fixing component, this utility model enhances the basketball inflation device by making it easier to fix the pump to the ground when inflating the basketball. This eliminates the need for the user to use their legs to hold the pump in place, reducing the likelihood of the pump becoming loose due to leg fatigue and making inflation difficult. This improves the convenience of using the pump and enhances its stability during inflation. Attached Figure Description

[0030] 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.

[0031] As attached Figure 1-6 As shown, one embodiment of this utility model provides an inflation device for easily securing a basketball, including an air pump 1. A mounting bracket 2 is fixedly connected to the lower surface of the air pump 1. A connecting rod 3 is fixedly connected to one side of the mounting bracket 2. A mounting box 4 is fixedly connected to one end of the connecting rod 3. A bidirectional lead screw 5 is rotatably connected inside the mounting box 4. A knob 6 is fixedly connected to one end of the bidirectional lead screw 5. Moving rods 7 are threaded to both ends of the bidirectional lead screw 5. The two moving rods 7 are slidably connected inside the mounting box 4. A clamping assembly is provided on the outside of the moving rods 7. The mounting bracket 2 is used to mount the air pump 1. The two ends of the bidirectional lead screw 5 are set with threads in opposite directions. The moving rods 7 facilitate the movement of the limiting plate 12, thereby bringing it closer to the basketball.

[0032] As attached Figure 4 As shown, the clamping assembly includes an adjusting shell 8, which is slidably connected to the outside of the moving rod 7. One end of the moving rod 7 is fixedly connected to a stud 9, and the stud 9 is threadedly connected to a nut 10. A fixing rod 11 is fixedly connected to the upper surface of the adjusting shell 8, and one end of the fixing rod 11 is fixedly connected to a limit plate 12. The stud 9 facilitates the installation of the nut 10, thereby fixing the adjusted shell 8 after it has been moved.

[0033] As attached Figure 5 As shown, two springs 13 and two outer tubes 14 are fixedly connected to one side of the limiting plate 12. The outer tubes 14 are located inside the springs 13. The inner tubes 15 are slidably connected inside the outer tubes 14. One end of each of the two inner tubes 15 is fixedly connected to a fastening plate 16. The outer tubes 14 and inner tubes 15 help to protect the springs 13. The springs 13 improve the tightness of the basketball fixation and help to cushion and protect the basketball when it is fixed.

[0034] As attached Figure 3 As shown, a placement shell 17 is fixedly connected to the upper surface of the mounting box 4. Fixing components are provided on both sides of the mounting frame 2. The fixing components include fixing plates 18. The two fixing plates 18 are fixedly connected to the two sides of the mounting frame 2 respectively. Threaded tubes 19 are rotatably connected to the upper surfaces of the two fixing plates 18 and the connecting rod 3. Through slots 20 are opened on the upper surfaces of the two fixing plates 18 and the connecting rod 3. The placement shell 17 is convenient for placing basketballs, and the threaded tubes 19 are convenient for installing screws 21.

[0035] As attached Figure 6 As shown, the threaded tube 19 is internally threaded with a screw 21, and the through groove 20 is internally slidably connected with a limit rod 22. One end of the limit rod 22 and the screw 21 is fixedly connected with a connecting plate 23. The lower surface of the connecting plate 23 is fixedly connected with a suction cup 24. The screw 21 facilitates pushing the connecting plate 23 downward, so that the suction cup 24 is close to the ground.

[0036] As attached Figure 2 As shown, small synchronous pulleys 25 are fixedly connected to the outside of two threaded tubes 19, and two large synchronous pulleys 27 are fixedly connected to the outside of the other threaded tube 19. A knob 26 is fixedly connected to the upper surface of one of the small synchronous pulleys 25. A synchronous belt 28 is provided between the small synchronous pulley 25 and the large synchronous pulley 27. The connection between the large synchronous pulley 27 and the small synchronous pulley 25 facilitates the simultaneous rotation of the three threaded tubes 19.

[0037] Working principle: When inflating a basketball, first use the fixing components to fix the inflation device to the ground. When fixing the basketball to the inflation device, first adjust the height of the limiting plate 12 according to the size of the basketball and the required limiting height. Tighten the nut 10 to release the nut 10 from contact with one side of the adjusting shell 8, so that the stud 9 can slide on one side of the adjusting shell 8. Then move the position height of the adjusting shell 8 outside the moving rod 7. After adjustment, tighten the nut 10 on the stud 9 to fix the height of the adjusting shell 8 and fix the height of the limiting plate 12. Then place the basketball inside the placement shell 17 and turn the knob 6 to drive the double-acting screw 5 to rotate. Through the action of the opposite threads at both ends of the double-acting screw 5, it is easy to drive the two moving rods 7 to slide inside the mounting box 4 and move closer to each other. This helps to make the fastening plate 16 fit tightly against both sides of the basketball, thereby facilitating the limiting of both sides of the basketball and improving the fixing effect of the basketball.

[0038] When the device is fixed to the ground using the fixing components, turning the knob 26 causes the corresponding small synchronous wheel 25 to rotate. When the small synchronous wheel 25 rotates, it drives the corresponding large synchronous wheel 27 to rotate through the connection of the synchronous belt 28. The large synchronous wheel 27, connected to the corresponding threaded tube 19, drives another large synchronous wheel 27 to rotate. This, in turn, drives another small synchronous wheel 25 to rotate through the connection of the other synchronous belt 28. This helps to drive the three threaded tubes 19 to rotate simultaneously. As the threaded tubes 19 rotate, the limiting rod 22 slides through the through groove 20, which facilitates the downward movement of the screw 21. The screw 21 then drives the suction cup 24 to move downward through the connecting plate 23. The suction force of the suction cup 24 is used to easily adhere to the ground, improving the stability of the inflation device during use.

[0039] 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.
