[0002] As the concept of environmental protection is deeply rooted in the hearts of the people, more and more residents choose to travel by bicycle; the traditional pump has a straight structure, which is large in size and inconvenient to carry; some products are made in small size, but they need to be pushed for a long time when they are used The piston rod is relatively laborious; in addition, when these pumps are used, the human body needs to spend a lot of effort, and at the same time it needs to bend over to operate, and the range of motion is relatively large, which is laborious and inconvenient to use; because the pumping operation is the human body pushing and pulling the piston rod Reciprocating motion, therefore, in each reverse motion, there is inertial energy consumption, laborious and inefficient in pumping operation

Embodiment
[0019] exist figure 1 , figure 2 In the shown embodiment, the crank handle portable pump includes a base 1, an inflator 2, a one-way air outlet nozzle 21, and a one-way air intake valve 22;
[0020] The inflator 2 is arc-shaped, and the one-way air outlet 21 is installed at the midpoint of the arc; the one-way air outlet 21 communicates with the inflator 2 through a soft conduit; in the inflator 2, a single To both sides of the air outlet nozzle 21, the piston 3 is symmetrically slidably installed;
[0021] The handle portable pump also includes a drive plate 4 and a guide rail 5; the drive plate 4, the guide rail 5 and the inflator 2 are installed on the base 1, and the drive plate 4 can freely rotate around its own axis;
[0022] A transmission column 51 is slidably installed on the guide rail 5, and a drive handle 41 is installed on the circular surface of the drive disk 4; the drive handle 41 and the transmission column 51 are connected and transmitted through the conne...

The invention relates to a crank-operated portable inflator. The crank-operated portable inflator comprises a base seat, an inflator pump, a one-way air outlet nozzle, a one-way air inlet valve, a driving disc and a guide rail; in the inflator pump, pistons are symmetrically mounted on the two sides of the one-way air outlet nozzle in a sliding manner; the driving disc, the guide rail and the inflator pump are mounted on the base seat; a transmission post is mounted on the guide rail in a sliding manner; a driving handle is mounted on the circular surface of the driving disc; the driving handle and the transmission post are connected with each other through a connecting rod to realize transmission; a guide chain is fixedly connected with the end part of each piston; the other end of each guide chain is fixedly connected with the transmission post; each guide chain can be made of a twistable ferromagnetic chain; guide chain posts are fixed to the two ends of the inflator pump; a guide chain rod which is made of a permanent magnetic material is mounted between the guide chain post and the guide rail. The crank-operated portable inflator is ingenious in structure, small in size and convenient to carry; meanwhile, inflation is simple and labor-saving, and the inflating efficiency is effectively improved.
