Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0024] Reference Figure 1-Figure 5 A pressure-measuring and anti-falling air pump comprises an outer cylinder 1 and a slide cylinder 8. The slide cylinder 8 is slidably connected inside the outer cylinder 1. The outer cylinder 1 is made of ABS material. The upper end of the slide cylinder 8 is fixedly connected to a pressure gauge 5 (the pressure gauge 5 is a prior art and will not be explained in detail here).

[0025] The two sides of the upper end of the slide 8 are respectively fixedly connected with the docking tube 6, one end of the docking tube 6 is threadedly connected to a nut 15, and the end of the nut 15 away from the docking tube 6 is rotatably connected to the external tube 14, and the two sides of the pressure gauge 5 are respectively fixedly connected with the handles 7, the lower end of the outer tube 1 is fixedly connected to the base 12, and through holes are respectively opened at both ends of the base 12, and a suction cup 13 is slidably connected in the through hole, and the upper end of the suction cup 13 is fixedly connected to the straight tube 11, and the outer surface of the outer tube 1 is fixedly connected with a fixing ring 10, and circular rings 2 are respectively fixedly connected on both sides of the fixing ring 10. The circular ring 2 realizes the limiting effect on the straight tube 11, and the upper ends of the two straight tubes 11 are respectively slidably connected in the circular ring 2.

[0026] The outer surface of the outer tube 1 is provided with a thread, and the outer tube 1 is threadedly connected to a wire cap 4, and the lower end of the wire cap 4 is rotatably connected to the airbag 3. The airbag 3 is arranged in a ring shape, and the lower end is fixedly connected to the upper surface of the fixing ring 10. The airbag 3 is sleeved on the outer tube 1, and the airbag 3 can be stretched while the wire cap 4 rotates and moves upward. The two straight tubes 11 are fixedly connected with a connecting pipe 9, and the end of the connecting pipe 9 away from the straight tube 11 is connected to the airbag 3.

[0027] Limiting rings 17 are fixedly connected on both sides of the pressure gauge 5, and multiple springs 16 are fixedly connected to the side walls of the limiting rings 17. A sealing ring 18 is fixedly connected to one end of the multiple springs 16 away from the limiting rings 17. The sealing ring 18 is slidably connected to the outer surface of the docking tube 6. An upper cover 19 is slidably connected to the pressure gauge 5, and the upper cover 19 is used to protect the pressure gauge 5.

[0028] In the present utility model, when in use, first place the base 12 on a smooth ground, then push the straight cylinder 11 downward, and the suction cup 13 passes through the base 12 as the straight cylinder 11 moves downward and contacts the ground, then rotate the wire cap 4, and the wire cap 4 can move upward on the outer cylinder 1 and stretch the air bag 3 when rotating. The air bag 3 is connected to the straight cylinder 11 through the connecting tube 9. Therefore, when the air bag 3 is stretched, negative pressure is generated in the straight cylinder 11 and the suction cup 13, so that the suction cup 13 can be more stably adsorbed on the ground, and the straight cylinder 11 is used to limit the base 12, so that the outer cylinder 1 can stand on the ground through the base 12, which is convenient for continuously inflating the ball.

[0029] When the nut 15 is turned, the thread 15 moves toward the pressure gauge 5 when it rotates on the docking tube 6, squeezing the sealing ring 18 and compressing the spring 16 while being threadedly fixed to the docking tube 6. At this time, the sealing ring 18 is in contact with and squeezed against one end of the nut 15, thereby achieving a further sealing effect on the nut 15 and the docking tube 6.

[0030] At this time, the gas in the outer tube 1 enters the sphere through the butt joint 6, the nut 15 and the outer tube 14. At the same time, the pressure gauge 5 can detect the air pressure in the sphere in real time for subsequent inflation.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.
