Description

Technical Field

[0001] This utility model belongs to the technical field of air inflation tools, and more specifically, it relates to a portable plastic air pump. Background Technology

[0002] An air pump is a tool used to inflate objects. Common uses include inflating tires, air cushions, sporting goods (such as soccer balls and basketballs), balloons, etc. It typically consists of a cylinder, piston, nozzle, and handle, and uses manual or electric methods to generate pressure, forcing air into the target object.

[0003] Based on the above, the inventors have discovered the following problems: In the process of using existing air pumps, most air pumps are not convenient to carry because the foot pads and handles take up a lot of space, thus reducing the user experience.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a portable plastic air pump, in order to achieve a more practical value. Utility Model Content

[0005] The purpose and function of this portable plastic air pump are achieved by the following specific technical means:

[0006] A portable plastic air pump includes an air pump body, which includes a high-pressure coil, a cylinder, and a piston. The piston is slidably connected to the cylinder. An mounting plate is installed on the top of the piston. A pair of mounting seats 1 are installed on both sides of the mounting plate. A handle is movably installed between each pair of mounting seats 1. A pair of mounting seats 2 are installed on both sides of the bottom of the air pump body. A foot plate is movably installed between each pair of mounting seats 2.

[0007] Furthermore, a rotating ring is rotatably mounted between each pair of mounting bases via a hinge, the handle passes through the rotating ring and is threadedly connected to the rotating ring, and a pair of threaded holes are provided on both sides of the mounting plate, with one end of the handle threadedly connected to the threaded hole.

[0008] Furthermore, the other end of the handle is threaded with a rotating cover, and the handle has a storage slot inside.

[0009] Furthermore, each pair of mounting bases is rotatably connected to one end of the foot plate via a hinge. A pair of connecting blocks are installed on both sides of the bottom end of the air cylinder body. A ball plug is installed at one end of each connecting block. The surface of the foot plate is provided with a groove that matches the ball plug. The ball plug is embedded in the groove.

[0010] Furthermore, the ball plug is made of rubber.

[0011] Furthermore, the high-pressure pack is located at the top of the air cylinder body, and a pressure gauge is installed at the top of the high-pressure pack.

[0012] Furthermore, an air pipe is provided at the top of the air cylinder body, and an air nozzle is installed at the top of the air pipe. The air pipe is engaged with a retainer on the cylinder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By rotating the handle to disengage it from the threaded hole, and then rotating the handle downwards, the rotating ring will follow the rotation, allowing the handle to be folded up, thus avoiding the handle taking up too much space and making it easier for people to carry. When in use, rotate the handle upwards, and then rotate the handle to connect it to the threaded hole, so that the air pump can be inflated, improving its practicality.

[0015] By rotating and removing the cover, replacement parts or needles can be placed in the storage slot, preventing them from being lost and saving storage space, thus providing practicality.

[0016] By lifting the foot plate upwards, the ball plug is embedded in the slot, allowing the foot plate to retract, saving space, making it easier for people to carry, and improving practicality. Attached Figure Description

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a portable plastic air pump, including an air pump body 1. The air pump body 1 includes a high-pressure pack 2, an air cylinder 3, and a piston 4. The piston 4 is slidably connected to the air cylinder 3. An mounting plate 7 is installed on the top of the piston 4. A pair of mounting seats 11 are installed on both sides of the mounting plate 7. A handle 10 is movably installed between each pair of mounting seats 11. A pair of mounting seats 2 19 are installed on both sides of the bottom of the air pump body 1. A foot plate 8 is movably installed between each pair of mounting seats 2 19.

[0029] Each pair of mounting bases 11 is rotatably mounted with a rotating ring 12 via a hinge. The handle 10 passes through the rotating ring 12 and is threadedly connected to it. The mounting plate 7 has a pair of threaded holes 13 on both sides. One end of the handle 10 is threadedly connected to the threaded hole 13. By rotating the handle 10, it is disengaged from the threaded hole 13. Then, by rotating the handle 10 downward, the handle 10 can be folded up, avoiding the handle 10 taking up too much space and making it easy for people to carry. When in use, the handle 10 is rotated upward and then rotated to be threadedly connected to the threaded hole 13, which can inflate the air pump, improving its practicality.

[0030] The other end of the handle 10 is threadedly connected to a rotating cover 14. The handle 10 is provided with a storage slot 15. By rotating the rotating cover 14 and removing it, the replacement part or air needle can be placed in the storage slot 15, which can prevent the replacement part from being lost, save storage space, and provide practicality.

[0031] Each pair of mounting bases 19 is rotatably connected to one end of the foot plate 8 via a hinge. A pair of connecting blocks 16 are installed on both sides of the bottom end of the air pump body 1. A ball plug 17 is installed at one end of each connecting block 16. The surface of the foot plate 8 is provided with a groove 18 that matches the ball plug 17. The ball plug 17 is embedded in the groove 18. By lifting the foot plate 8 upward, the ball plug 17 is embedded in the groove 18, allowing the foot plate 8 to be retracted, saving space, making it easy for people to carry, and improving practicality.

[0032] The ball plug 17 is made of rubber, which can increase the friction between the ball plug 17 and the slot 18, thus stabilizing the foot plate 8.

[0033] The high-pressure pack 2 is located at the top of the air cylinder body 1, and a pressure gauge 9 is installed at the top of the high-pressure pack 2.

[0034] The air cylinder body 1 has an air pipe 5 at its top end, and an air nozzle 6 is installed at the top end of the air pipe 5. The air pipe 5 is engaged with a retainer on the cylinder 3.

[0035] The specific usage and function of this embodiment are as follows:

[0036] First, check the integrity of the device. Only use it after confirming that everything is correct. When using it, first align the air nozzle 6 with the air inlet, press the handle 10, and the piston 4 moves in the cylinder 3, generating negative and positive pressure. Read the pressure value from the pressure gauge 9 on the high-pressure pack 2. After inflation is complete, rotate the handle 10 to disengage it from the threaded hole 13, and then rotate the handle 10 downwards. The rotating ring 12 will follow the rotation, allowing the handle 10 to be retracted, thus avoiding the handle 10 taking up too much space. By lifting the foot plate 8 upwards, the ball plug 17 is embedded in the slot 18, allowing the foot plate 8 to be retracted. The rubber ball plug 17 can increase the friction with the slot 18, stabilizing the foot plate 8, saving space and making it easy for people to carry. Rotate the rotating cover 14 and remove it. Place the replacement part or air needle in the storage slot 15 to prevent the replacement part from being lost, while saving storage space and improving practicality. This device has a novel overall design and simple structure, so it is worth promoting and using widely.
