[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The utility model provides a foldable foot pump, such as Figures 1 to 5As shown, in this embodiment, it includes a base 1 and a foot pedal 2 rotatably connected to the base 1, a cylinder 3 assembly is arranged between the base 1 and the foot pedal 2, the cylinder 3 assembly includes multiple cylinders 3, and also includes a three-way bracket 5 and a decorative plate 4, both ends of the three-way bracket 5 are provided with a connecting hole, two first connecting parts 21 are correspondingly arranged on the foot pedal 2, and two second connecting parts 41 are correspondingly arranged on the decorative plate 4, one end of a screw without a nut can pass through a first connecting part 21 and a second connecting part 41 in sequence and be tightened in the connecting hole to achieve a fixed connection between the foot pedal 2, the decorative plate 4 and the three-way bracket 5, in addition to using screws to connect the foot pedal 2, the decorative plate 4 and the three-way bracket 5, other non-destructive detachable connecting parts such as pins can also be used for connection, the three-way bracket 5 has a ventilation cavity 54 that can be connected and communicated with the air outlet of the cylinder 3, an air belt 6 can be connected and communicated with the ventilation cavity 54, and the decorative plate 4 is provided with a accommodating groove 44 that can accommodate the air belt 6.

[0028] The foldable foot pump provided by the utility model can realize the fixed connection between the foot pedal 2, the decorative plate 4 and the three-way bracket 5 by screwing the screw through the first connecting part 21 and the second connecting part 41 in sequence and tightening them in the connecting hole. The foot pedal 2 and the decorative plate 4 can both rotate around the axis of the screw. When the foot pedal 2 is stepped on, the piston in the cylinder 3 moves downward to compress the gas, thereby generating high-pressure gas. The high-pressure gas enters the air belt 6 through the ventilation cavity 54. An inflation joint 7 is provided at the air outlet of the air belt 6. The inflation joint 7 can be connected to the object to be inflated. Inflation can be achieved by continuously stepping on the foot pedal 2. When the foldable foot pump needs to be repaired or disassembled, the foot pedal 2, the decorative plate 4 and the three-way bracket 5 can be removed by unscrewing the screws. The operation is convenient and does not require professional skills. By repairing or maintaining the parts, the economy can also be improved. The accommodating groove 44 on the decorative plate 4 can accommodate the air belt 6 to prevent the air belt 6 from being scattered outside and causing damage to it.

[0029] The three-way bracket 5 is provided with an air outlet head 51 and a plurality of connecting heads 52. The air outlet head 51 and each connecting head 52 are connected and communicated with the ventilation cavity 54. The air outlet head 51 can be connected and communicated with the air belt 6. Each connecting head 52 can be connected and communicated with the air outlet of a cylinder 3. There are preferably two connecting heads 52. The cylinder 3 is also provided with two. One cylinder 3 can be connected to one connecting head 52. The cylinder 3 includes a hollow inner tube, an outer tube with an opening at one end and a piston. An end cover of the outer tube opening is provided with an air inlet cover. The air inlet cover can be clamped on the outer tube by a buckle. The top end of the inner tube can be threadedly connected to the connecting head 52. The other end of the inner tube can pass through the air inlet cover and extend into the outer tube. The inner tube is provided with a piston at one end of the outer tube. A piston rubber ring is provided at the bottom of the piston to prevent gas from leaking from the air chamber formed between the inner tube and the outer tube.

[0030] The air cylinder 3 may also use other existing air-inflating air cylinders 3. The foldable foot pump provided by the utility model can generate relatively high air pressure and can meet the inflation operations with various air pressure requirements.

[0031] The three-way bracket 5 is also provided with a pressure measuring head 53 connected to the ventilation cavity 54. A pressure gauge 8 is provided at the pressure measuring head 53. The pressure gauge 8 can be used to detect the output air pressure value of the foldable foot pump to prevent over-inflation and improve the safety of use.

[0032] The decorative panel 4 includes an inner cylinder 42 and an outer cylinder 43 which are coaxially arranged. The barometer 8 can be placed in the inner cylinder 42. The outer wall of the barometer 8 can fit with the inner wall of the inner cylinder 42. The barometer 8 can be threadedly connected and fixed at the pressure measuring head 53. By sleeve-arranging the inner cylinder 42 outside the barometer 8, the inner cylinder 42 can also protect the barometer 8. An annular receiving groove 44 is formed between the inner cylinder 42 and the outer cylinder 43, and the air belt 6 can be coiled in the receiving groove 44.

[0033] The decorative panel 4 also includes a baffle 45 fixedly connected to the outer wall of the outer tube 43. The baffle 45 can protect the cylinder 3. The baffle 45 has a limit card 46. One end of the air belt 6 provided with an inflation connector 7 can be clamped in the limit card 46 to prevent the received air belt 6 from escaping from the accommodating groove 44.

[0034] One end of each cylinder 3 is threadedly connected to the connector 52 and the other end has a connecting through hole. A connecting rod is used to pass through the base 1 and the connecting through hole in sequence to rotatably connect the cylinder 3 to the base 1.

[0035] A connecting shaft 11 can pass through the base 1 and the foot pedal 2 in sequence to realize the rotational connection between the base 1 and the foot pedal 2. A limit screw is provided at both ends of the connecting shaft 11. A torsion spring 12 is sleeved on the connecting shaft 11. One output end of the torsion spring 12 abuts against the base 1, and the other output end of the torsion spring 12 abuts against the foot pedal 2. The torsion spring 12 can reset the stepped foot pedal 2 after the external force is lost.

[0036] A limit block 13 is slidably provided on the base 1, and a limit hook 22 is correspondingly provided on the foot pedal 2. The foot pedal 2 is stepped on and the limit block 13 is slid at the same time, so that the limit block 13 is extended into the limit hook 22 so that the relative position between the foot pedal 2 and the base 1 is kept fixed, and the foldable foot pump can be folded; the foot pedal 2 is stepped on and the limit block 13 is slid at the same time so that the limit block 13 is disengaged from the limit hook 22, and the folded state of the foldable foot pump can be released.

[0037] A plurality of anti-skid shock-absorbing plugs 14 are evenly arranged at the bottom of the base 1. Preferably, there are four anti-skid shock-absorbing plugs 14, which are distributed at the four corners of the bottom of the base 1. When the operator steps on the pump to inflate, the anti-skid shock-absorbing plugs 14 can prevent the foldable foot pump from sliding on the ground. At the same time, the anti-skid shock-absorbing plugs 14 can improve the stability of the foldable foot pump.

[0038] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
