[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figures 1-4 The present application provides a technical solution: a foot pressing type air pump with a limiting device, which comprises a bottom plate 1, an air cylinder barrel 2 and a pressure gauge arranged on the upper end of the bottom plate 1, an air pipe 3 connected with the air cylinder barrel 2, a pedal 4 mounted on the top of the air cylinder barrel 2, and a limiting component arranged on the bottom of the bottom plate 1.

[0025] The limiting part comprises a limiting groove opened in the bottom of the bottom plate 1, a limiting plate 5 slidably arranged in the limiting groove through a guide rail, a treading groove 6 opened on the surface of the limiting plate 5, and an anti-skid groove opened on the surface of the treading plate 4 and the treading groove 6, so that when inflating, the feet can be pressed in the treading groove 6 to increase the friction and stability and prevent the inflator from shaking during inflation, and the treading plate 4 is more stable than the conventional limiting iron ring.

[0026] Open grooves 7 are also opened on both sides of the treading groove 6 on the upper end surface of the limiting plate 5, and protective plates 8 are slidably arranged in the open grooves 7, and the two groups of protective plates 8 are hingedly connected through a pin shaft, and springs for pushing the protective plates 8 are arranged in the inner sides of the open grooves 7, and a magnet piece 10 is arranged on the side wall of the limiting groove, and the limiting plate 5 is made of iron metal material, and the magnet piece 10 and the side wall of the limiting plate 5 are matched to store and adsorb the limiting plate 5 when the limiting plate 5 is not used, so as to prevent the limiting plate 5 from sliding;

[0027] In order to ensure the normal sliding and storage of the protective plates 8, the open grooves 7 are arranged in an inclined shape, that is, the two ends are low and the end close to each other is high, so that when the limiting plate 5 slides out of the limiting groove, the protective plates 8 can be automatically popped up under the action of the springs, and when the limiting plate 5 is stored in the limiting groove, the limiting plate 8 is extruded by the limiting groove to be stored again.

[0028] Therefore, when using the inflator, the limiting plate 5 is pulled out of the limiting groove, and when the limiting plate 5 slides out, the two groups of protective plates 8 can be close to each other and arch under the action of the springs, so that the operator can step on the treading groove 6 and press the protective plates 8 on the instep to increase the limiting and ensure the stability of the inflator during inflation.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
