Description

Easy-to-use air pump

This creation mainly discloses an air pump, especially an air pump that is convenient to use.

Please refer to the "inflator" patent case of Chinese Patent No. I262990, which is an inflator including a trachea assembly and an inflating member. The inflating member uses the connecting rod and the cylinder to move the gas to the air pipe assembly to inflate the wheel. The trachea assembly can be set as a first trachea and a second trachea connected with an adapter piece, and the adapter piece can be buckled on the head of the inflating member during storage. In addition, the trachea assembly can also be set as a single elongated trachea, which is hung on the head of the inflating member at the middle section. And a fastening piece can be set at the cylinder body of the inflating member, and the second air pipe or a single extended air pipe is fastened to the fastening piece.

However, the handle of the above-mentioned pump is pivotally connected to the head of the end of the connecting rod. Although the handle can be unfolded and folded, the angle cannot be completely fixed after unfolding. As a result, the handle will still swing and shake during the pumping process of the user, causing inconvenience to the user. Moreover, although the trachea assembly can be stored and fixed, the trachea assembly is still outside the pump after being stored. If the user stores the pump and other items together, the trachea assembly is likely to catch other items.

In view of the lack of the above-mentioned conventional structure, the creator has designed a convenient pump, which can overcome all the shortcomings of the above-mentioned conventional structure.

The connection part, the operating rod can be connected to the piston rod in the first state or the second state. When the operating rod is in the first state, the second connecting part is connected to the first connecting part. When the operating rod is in the second state, the third connecting part is connected to the first connecting part. When the operating rod is switched between the first state and the second state, the operating rod is separated from the piston rod. The pump can be easily operated by the user through the above structure.

In the state, the operating rod closes the accommodating groove.

The long side of the operating rod extends axially along a virtual reference line, one end of the operating rod along the axial direction of the reference line is recessed with a socket, the second connecting portion is arranged at the end of the socket opposite to its opening, when the operating rod is in the first state, the socket is sleeved on the piston rod, and the third connecting portion is arranged on the outer periphery of the operating rod radially along the reference line.

The end of the cylinder opposite to the head is connected with an end cover, the piston rod passes through the end cover and is inserted into the cylinder, when the operating rod is in the first state, one end of the operating rod along the reference line axially abuts against the end cover.

One end of the head opposite to the cylinder is provided with an abutting portion, and the abutting portion is plane.

The first connecting part is arranged on the radially outer periphery of the piston rod and is provided with an external thread structure. The second connecting part and the third connecting part are respectively provided with internal thread structures. When the operating rod is in the first state, the second connecting part is connected to the first connecting part in a screw-lock manner, and the reference line is parallel to the axial direction of the piston rod. When the operating rod is in the second state, the third connecting part is connected to the first connecting part in a screw-locking manner, and the reference line is perpendicular to the piston rod.
