Description

Technical Field

[0001] The present invention mainly relates to an air pump, in particular to a foldable air pump. Background Art

[0002] Please refer to Taiwan Patent No. M527494, "Easy-to-assemble air pump with storable hose", which discloses an easy-to-assemble air pump with storable hose, mainly comprising a fixed cylinder, a movable cylinder and a hose; the movable cylinder is sleeved with the fixed cylinder and can move back and forth relative to the fixed cylinder, the fixed cylinder has a connecting hole and a gate plate inserted into the connecting hole, the movable cylinder has a hose chamber and a detachable cover, the hose can be placed in the hose chamber of the movable cylinder for storage, and can also be taken out from the hose chamber. When the gate plate is in a loose position, the hose can be inserted into the connecting hole. When the gate plate is in a locking position, the gate plate and the hose are locked.

[0003] However, the above-mentioned air pump needs to reassemble the hose each time it is used and re-store the hose after use. Moreover, since the hose is detachable, the opening of the hose chamber still needs to be sealed with a cap after the hose is stored in the hose chamber. However, the cap itself is easy to lose, which causes a lot of inconvenience when assembling and disassembling the hose. Summary of the Invention

The French thread 342 can be connected to a French gas nozzle. The O-ring 343 is disposed between the US-style thread 341 and the French thread 342.

[0025] The slide 31 is provided with two buckle grooves 312 , and a lug 332 is respectively provided on opposite sides of the pivot joint 33 . The pivot joint 33 is pivotally connected to the slide 31 and is located between the two buckle grooves 312 , so that the lug 332 protrudes into the two buckle grooves 312 .

[0026] The pump 20 includes a head seat 23, which is connected to the second end 212. The head seat 23 is provided with an opening 231 at the end opposite to the inner cylinder 21 and a side hole 232 connected to the opening 231 is provided on the side. When the slide 31 is in the extended position and the pivot joint 33 is in the axial position, the inflation group 30 protrudes from the head seat 23 through the opening 231. When the pivot joint 33 is in the radial position, the inflation group 30 protrudes from the head seat 23 through the side hole 232.

[0027] When the slide 31 is in the retracted position, the inflation assembly 30 does not protrude from the opening 231 . The pump 20 includes a cover 24 detachably connected to the opening 231 and capable of closing the opening 231 .

[0028] The cover 24 is connected to an anti-lost portion 241 . The anti-lost portion 241 is flexible and can be deformed arbitrarily. The anti-lost portion 241 is always connected to the head base 23 .
