Embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.
A kind of portable tire pump as shown in Figure 1 and Figure 4, comprise the valve 1, stack shell 2, the jacket casing 3 that are provided with the first one-way valve 4, valve 1 connects stack shell 2, stack shell 2 comprises portion of the handle 7, rubber cup 9 and connects the cylinder bar 8 of portion of the handle 7 and rubber cup 9, jacket casing 3 is hollow structure, and jacket casing 3 end face centers are provided with the first through hole 10, and jacket casing 3 is installed on the cylinder bar 8 of stack shell 2 by through hole 1, jacket casing 3 can be along 8 axial motions of cylinder bar, and jacket casing 3 bottom surfaces are provided with the second through hole 12 with the second one-way valve 11.Be provided with annular groove 5 near portion of the handle 7 places of stack shell 2 on the valve 1, during inflating ball balloon be enclosed within on the valve and with the balloon mouth and be buckled in the annular groove place, guarantee that balloon can not leak gas at gas-filled type.Cylinder bar 8, portion of the handle 7 inside are equipped with air flue and are communicated with valve 1, jacket casing 3.Portion of the handle 7 is provided with the circular arc recess 6 suitable with human finger, and the person of being easy to use grasps portion of the handle during use.Jacket casing 3 outer surfaces are provided with ring rib 13, can increase the frictional force of the relative jacket casing outer surface of gesture and facial expression, and it is easier to make when inflating.Pump is made of plastics, and can effectively alleviate overall weight, reaches portable purpose.
Phase diagram when using for this portable tire pump as shown in Figures 2 and 3, during use balloon is enclosed within on the valve and with the balloon mouth and is buckled on the annular groove, one holds portion of the handle, one holds jacket casing and axially spurs back and forth jacket casing along the cylinder bar, air can enter in the jacket casing by the second through hole of jacket casing bottom surface like this, then air tube cover compression, and by cylinder bar, portion of the handle, valve, be pressed at last in the balloon, because the setting of first, second one-way valve, air only can move along a direction, can not produce backflow.
Therefore, this portable tire pump is not only easy to carry, and is lightweight, simple in structure, modern design, and also cheap for manufacturing cost, have practicability.
But the above only is better possible embodiments of the present utility model, is not to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, all in like manner is included in the scope of the present utility model.
