Abstract
The utility model relates to an air inflator, particularly a portable air inflator with a buffering function. The utility model is composed of a piston barrel, a two-way joint, a connecting duct, a connecting cover and an air inlet nozzle, wherein one end of the two-way joint is fixedly connected with the piston barrel, the other end of the two-way joint is connected with the connecting cover, the inner side of the other end of the two-way joint is provided with a hemispherical groove, and the center of the two-way joint is provided with an air inlet hole. The end part of the connecting cover is provided with a through hole, and the inner side of the through hole is provided with a ball table-shaped side face. The upper end of the connecting duct is provided with a hemisphere, the radius of the hemisphere is not greater than the radius of the hemispherical groove, the hemisphere is provided with a sealing ring, the hemisphere is arranged in the hemispherical groove, and the sealing ring is pressed on the side wall of the hemispherical groove; the center of the connecting duct is provided with a spacing ring, the lower end of the connecting duct is provided with a packing washer and the connecting duct penetrates through the through hole on the connecting cover and then is connected with the air inlet nozzle. The utility model causes the inflating work to have the buffer function, and the fatigue degree of the inflating work can be lightened.
Description
Technical field
The utility model is a kind of being used for to tire or ball inflator of inflating, particularly a kind of portable tire pump with pooling feature.
Background technique
Portable tire pump of the prior art, its advance that device is chewed and piston cylinder between be to be rigidly connected, there is not pooling feature, so in use, hold that hand of piston cylinder, can only when the another hand is firmly inflated, hold that hand of piston cylinder and just feel tired especially inflexibly being held on the position.
Summary of the invention
The purpose of this utility model be invention a kind of advance device chew with piston cylinder between be the portable tire pump that universal property is connected with pooling feature.
The utility model is realized as follows: the portable tire pump with pooling feature described in the utility model, and chew by piston cylinder, two-way joint, connecting duct, connecting cover and air inlet and to form; One end and the piston cylinder of two-way joint are affixed, and the other end of two-way joint is connected (being spirally connected) with connecting cover, and the inboard of the other end of this two-way joint is a hemisphere groove, and the central authorities of two-way joint are provided with inlet hole; The end of connecting cover is provided with a through hole, and the inboard of this through hole is the side of a billiard table shape, and the radius of this billiard table shape side equates that with the radius of hemisphere groove this side and this hemisphere groove constitute a diameter of Spherical Volume; The upper end of connecting duct is a hemisphere, the radius of this hemisphere is not more than the radius of hemisphere groove, and this hemisphere is provided with seal ring, this hemisphere is located in the hemisphere groove, and make seal ring press the sidewall of hemisphere groove, the central authorities of connecting duct are provided with position limit cycle, and the lower end of connecting duct is provided with seal ring, and connecting duct is to pass through hole on the connecting cover to chew with air inlet and be connected (being spirally connected).
During use, air inlet is chewed on the valve nozzle that is connected bicycle, at this moment, air inlet chew and valve nozzle between form a kind of relation that is fixedly coupled, and also be a kind of relation that is fixedly coupled between piston cylinder on the inflator and the connecting cover, these two are fixedly coupled relation and then connect into an integral body by connecting duct, because chew with air inlet the lower end of connecting duct is to fixedly connected, the hemisphere of connecting duct upper end then is arranged in the hemisphere groove of two-way joint, making two above-mentioned fixedly connected relations can be that arbitrarily rotate at the center with the hemisphere groove, so when inflating, air inlet is chewed and is fixed on the valve nozzle and can maintains static, can voluntary activity and hold piston cylinder, make the work of inflating have pooling feature, alleviated the degree of fatigue of the work of inflating greatly.
