Description
- The present invention relates to a bicycle pump and, more particular, to a bicycle pump with a universal head.
- Due to the rising of oil prices and the prevalence of exercise, many people use bicycles as a transport means for commuting and recreation. Riding a bike can bring benefits to the environment and achieve the effect of fitness. However, after a period of time, an inflated tire would gradually become flat. Thus, a user may prepare a floor bike pump at home. For enjoining the fun of riding a bike, a handheld bike pump is needed, which can be easily put into bags, pockets or can even be strapped to the bike. On the go, the handheld bike pump can be used to inflate a tire or help replacement of a tire whenever necessary.
- As to a conventional handheld bike pump, a tire should be turned to a position for easy connection to a valve of the tire, and then the tire can be pumped up properly. However, turning a bike's tire is not always convenient. In such condition, a proper connection between the bike pump and the tire's valve cannot be made easy.
- To facilitate a bicycle pump to fit to a tire of a bike, a Taiwan's utility model patent 463878 was disclosed, wherein a joint member is employed so that the head of the bike pump can be rotated universally for easy connection to the bike's tire. However, the joint member is constructed of a ball with a threaded rod, which has difficulty in the manufacturing and to reach a precision requirement. It is difficult to increase the quantity of acceptable joint members for final assembly. Thus, the manufacturing cost of this bike pump is relatively high.
- One object of the present invention is to provide a bicycle pump with a universal head, which allow the cylinder to be angled with respect to the head, so that the pump can be conveniently connected to the valve of a tire and the pumping operation can be conducted smoothly.
- Another object of the present invention is to provide a bicycle pump with a universal head, which is simple in structure and can be manufactured easily, and has a lower cost.
- Accordingly, the present invention provides a bicycle pump, which comprises a head, a socket, a ball, a retaining collar, a cylinder, and a piston unit. The head includes a housing provided with a connection portion and defining an air inlet and an air outlet that communicates with the air inlet. The socket is provided in the head and defines a round recess and a through hole communicating with the air inlet of the head. The ball, which is partially disposed in the round recess of the socket, defines a through hole communicating with the through hole of the socket, and has a connection portion. The retaining collar has an inner curved surface mated with an outer surface of a part of the ball located outside of the socket, and has a connection portion attached with the connection portion of the head, so that the ball can be retained between the socket and the retaining collar and rotated about its center in all directions. The cylinder defines a chamber therein. Also, the cylinder has a first connection portion at one end thereof and defines an air outlet at a center of the first connection portion, the air outlet of the cylinder communicating with the chamber, the first connection portion being attached with the connection portion of the ball, to allow the air outlet of the cylinder to communicate with the through hole of the ball. The piston unit is provided for conducting reciprocating motion along the chamber of the cylinder, so that air in the chamber can be forced out of the air outlet of the cylinder and finally forced out of the air outlet of the head to inflate a tire.
