Embodiment Construction

[0022] Regarding the technology, means and effects adopted in the present invention, a preferred embodiment is given and described in detail below with accompanying drawings, which are for illustration purposes only, and are not limited by this structure in patent applications.

[0023] refer to figure 1 , is a three-dimensional appearance view of the floor-mounted pump with a strong base structure of the present invention. The floor pump of the present invention includes a barrel 10 , an outer barrel 20 , a valve stem set 30 and a hose 40 . The barrel 10 is connected to the outer barrel 20, the valve stem set 30 is arranged on the barrel 10, and the valve stem set 30 reciprocates relative to the barrel 10 to produce an inflating effect, and the hose One end of the hose 40 is connected to the barrel 10, and the other end of the hose 40 is connected to the object to be inflated. The end of the outer cylinder 20 close to the ground has a larger cross-sectional area, so that th...

Abstract

The invention provides a vertical-type bicycle pump with a pedestal reinforcing structure, which comprises a cylinder part, an outer cylinder, a valve rod group and a hose. The cylinder part is provided with a cylinder body and a pedestal; the outer cylinder is sleeved with the cylinder body and is combined with the pedestal; the valve rod group is arranged on the cylinder body; the valve rod group does reciprocating movement relatively to the cylinder body to generate inflating effect; and one end of the hose is communicated with the cylinder part, and the other end of the hose is connected with an object to be inflated. The outer cylinder comprises a first end and a second end, wherein the sectional area of the second end of the outer cylinder is less than that of the first end of the outer cylinder; and the first end of the outer cylinder is combined with the pedestal. Therefore, the pedestal of the vertical-type bicycle pump of the invention has a better reinforcing structure and can be placed on the floor stably during inflation.

Description

technical field [0001] The invention relates to a floor-mounted pump, in particular to a floor-mounted pump with a strong base structure, which has good structural strength and can be stably placed on the ground when inflated. Background technique [0002] There are two common types of floor-mounted air pumps. The first type is that the base is pivotally connected with a tripod, and the operator selectively pulls the tripod. The second type of base is an enlarged design, and provides both ground support and footrests. [0003] Referring to U.S. Patent No. 5347913 (PORTABLE BICYCLE PUMP HAVING COLLAPSIBLE HANDLE AND FOOTSTAND), it belongs to the aforementioned first type of pump, which includes a cylinder 16, an inflator rod 20 and a communicating air pipe 34, wherein: the bottom end of the cylinder 16 is closed And be placed on the ground, the side of cylinder body 16 bottoms is provided with a tripod 32, and tripod 32 leans against the ground during operation, flatly stick...
