  • a user may prepare a floor bike pump at home.
  • a handheld bike pump is needed, which can be easily put into bags, pockets or can even be strapped to the bike.
  • the handheld bike pump can be used to inflate a tire or help replacement of a tire whenever necessary.
  • 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.
  • 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.
  • 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.
  • 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.

  • the air outlet 112 and the nozzle 133 are capable of accommodating a valve of a tire of a bike.
  • the nozzle 133 can be made of resilient material.
  • the pressing unit 13 is hermetically and movably mounted in the housing 11 and placed above the nozzle 133 .
  • the lever 12 is pivotally mounted to the housing 11 in cooperation with the pressing unit 13 , whereby when the lever 12 is pivotally moved from a first position (see FIG. 4 ) to a second position (see FIG. 5 ), the pressing unit 13 can be urged by the lever 13 to secure a valve on a tire of a bike.
  • the pressing unit 13 includes a pressing cup 131 and a plunger 132 fixed to the pressing cup 131 , where in the plunger 132 is inserted into the nozzle 133 ; the pressing cup 131 is engaged with the lever 12 , whereby when the lever 12 is located at the first position (see FIG. 4 ), the pressing cup 131 is not urged by the lever 12 ; when the lever is located at the second position (see FIG. 5 ), the lever 12 can urge the pressing cup 131 , which in turn drive the plunger to press the nozzle 133 and the tip of the valve 99 , thereby securing the valve 99 in the nozzle 133 .
  • the socket 20 which is provided in the annular member 113 of the head 10 , defines a round recess 21 and a through hole 22 communicating with the round recess 21 and the air inlet 111 of the head 10 .
  • the ball 30 is partially disposed in the round recess 21 of the socket 20 , wherein the ball 30 defines a through hole 32 communicating with the through hole 22 of the socket 20 and has a connection portion 31 .
  • the retaining collar 40 has an inner curved surface 42 , which is mated with an outer surface of a part of the ball 30 located outside of the socket 20 , and a connection portion 41 attached with the connection portion 114 of the head 10 , so that the ball 30 can be retained between the socket 20 and the retaining collar 40 and rotated about its center in all directions or universally.
  • connection portion 114 of the head 10 can be formed as external threads
  • connection portion 41 of the retaining collar 40 can be formed as internal threads, which can be threadedly engaged with the external threads of the head 10 .
  • the cylinder 50 defines a chamber 51 therein. Also, the cylinder 50 has a first connection portion 52 at one end thereof and has a second connection portion 54 at the other end thereof. Also, the cylinder 50 defines an air outlet 53 at a center of the first connection 52 and an opening 55 at the other end thereof; wherein both of the air outlet 53 and the opening 55 communicate with the chamber 51 .
