Description of the Invention: [Technical Field] The present invention mainly discloses a floor-mounted air pump cartridge having a strong structure of a base, which particularly refers to an air pump which has a good structural strength and is smoothly placed on the ground when pumping. [Prior Art] There are two types of grounding type air cylinders. The first type is that the base is pivotally connected with a foot frame, and the operator selectively pulls the foot frame. The second base is designed to increase the size and provide both ground and pedal. ^ Refer to China Patent Certificate No. M278776 "Inflator", which belongs to the first type of pump described above, and includes a cylinder (11), an airing rod (12), a connecting air tube (13), and a gas nozzle (14). Wherein: the bottom end of the cylinder (丨丨) is sealed and placed on the ground, and a side of the bottom end of the cylinder (11) is provided with a chat frame (15), and the tripod (15) is formed by bending a metal rod. The frame (15) is abutted against the ground during operation, and the stand (15) is attached to the cylinder (丨1) when it is stored, and the stand (15) can be collected although it has a moving force, but the pivot type Because the tripod (15) has the characteristics, when the pumping rod (12) is inflated with respect to the cylinder (11), the tripod and the cylinder (11) will sway, when the cylinder (11) cannot provide smoothness. The tube I φ temple will affect the efficiency of pumping, and a pump that will produce swaying, according to China Patent Certificate No. M260634 "Building-type pump (11) structural improvement", belongs to the aforementioned second pump , comprising a base body (12), a hose (13) and a connecting rod (14), the base (11) 5 1353415 combined with the same body (12) and a hose 13). However, the base (1)) and the barrel ((2) at the junction of the valley Yiwen to the connecting rod (14) continue to move up and down in the barrel (12) for a long time and affect the connection between the barrel (12) and the base (11). When operating the pump, The operator's foot is stepped on the base (11) 'The operating link (10) moves upward to draw the gas and moves downward to send the gas. When the connecting rod (l4) moves upward, the connecting rod 〇4) is connected with the piston, the piston and the barrel (12) Producing friction, the connecting rod (14) causes the barrel (12) to generate upward force, and stepping on the base (I) causes the base (I) to generate downward force, the base (11) and the barrel ( 12) It is pulled by the force in different directions, and the greater the force, the greater the torque the base (11) is subjected to, and the stress concentration of the base (π) will cause the base (11) and the barrel (12). The joint is broken, and the barrel (12) is designed to be straight in the same diameter. The joint between the barrel (12) and the base (11) has poor structural strength. Moreover, such a design simply abuts against the ground by the base (11), and the contact of the base (11) with the ground still has an unstable loss. Therefore, the conventional design has to be improved. It is desirable to eliminate or at least mitigate the problems encountered in the prior art by the present invention. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is that the combination of the base of the conventional floor-standing pump and the barrel has a lack of structural strength, and the base is There is an unsatisfactory lack of contact with the ground, and the conventional design does not meet the expectations of the operator, and needs to be improved.

In addition, a pressure gauge is disposed on the pumping cylinder of the second end 222 of the outer cylinder 22 of the tubular member group 20, and the first end 401 of the hose 40 is connected to the pressure gauge. In other words, the first end 401 of the hose 40 communicates with the tubular member group 20. The outer tube 22 has a second end 222. Referring to Figure 4, there is shown a cross-sectional view of a floor-mounted air pump having a base strong structure according to the present invention.

The first end 221 of the outer tube 22 has a large area. . The invention is discussed by the larger bottom area to obtain the pressure and bending moment which the bottom part has a better strong structure which can be subjected to a unit area: 9 1353415 /A; it can be known that when the applied force (7) is the same, the larger the area (4), the early area The pressure (p) tolerated is small, in other words, the larger the area, the more the pressure can be dissipated evenly, and the pressure tolerated is less than the damage. For the purpose of the present invention, the first end 221 of the outer cylinder 22 is coupled with the base 1 ,, the treading zone 12 of the bottom f 1 经由 is stepped on by the operator, and the base H) generates a downward force 2 2 - the eve end 221 has the largest The cross-sectional area, because the outer cylinder first-known 221 has a large area and the pressure per unit area is small, the first end 221 of the outer cylinder 22 has a better strong structure, and is less prone to damage by bending stress resistance, Torque * Rod half # / wearing surface moment of inertia to know that the rod is half-continuously resistant to f-curvature stress, the greater the rod bending resistance. For the purpose of the present invention, the first end of the outer cylinder 22 and thus the outer first end 221 can withstand the bending resistance II, and the first end of the outer cylinder 22 is preferably strong and strong. Not susceptible to damage. In addition to the above, the present invention has a large cross-sectional area with the base 1 except that the base 1G is in contact with the ground in a large area: at the outer end 2-! - Together, the error is made by the larger section 22 of the first end 221 of the outer cylinder 22 and the base 10 being placed on the ground smoothly.
