CN201496764U - Inflation metal tube - Google Patents

Abstract

An inflation metal tube comprises a sealed and hollow tube body; an inflation nozzle used for filling the inside of the tube body with compressed air is formed on the tube body; the thickness of the tube wall of the tube body ranges from 0.5 mm to 1.5 mm; and the tube wall of the tube body expands to the outside the tube body under the action of the compressed air entering the tube body from the inflation nozzle. The utility model has the advantages of light weight, simple structure, high strength, etc.

Description

The inflation metal tube

Technical field

The utility model relates to a kind of inflatable metal tube.

Background technique

In today of industry prosperity, metal tube is as a kind of industrial materials, in industrial products, use very extensive, vehicle frame such as common bicycle, the table body of desk, the chair body of office seat etc. locates all to have used metal tube, though these metal tubes have flexible good, advantages such as the product that is processed is attractive in appearance, but because requirements such as these industrial products self intensity, the metal tube of in industrial products, using, general its pipe thickness is thicker, and weight is heavier, these structural features directly cause using the industrial products weight of these metal tubes and the increase of cost, how further to reduce the weight of metal tube, and satisfy the requirement of the relevant intensity of industrial products, become a technical barrier that is difficult to break through.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of inflation metal tube, this inflation metal tube light weight and intensity height.

For solving the problems of the technologies described above, metal tube of the present utility model adopts following technical proposals: this inflation metal tube comprises the body of sealing and inner hollow, described body is provided with in order to fill the charging air inlet of putting pressurized gas to body inside, the pipe thickness of described body is 0.5mm～1.5mm, and the tube wall of described body expands to the body outside under the pressurized gas effect that enters body inside from charging air inlet.

According to design concept of the present utility model, described charging air inlet is positioned at the place, end of described body or is positioned at the side-walls of body.

For solving above-mentioned another technical problem, the utility model bicycle adopts following technical proposals: bicycle, comprise vehicle frame, and described vehicle frame is made by described metal tube, and described metal tube is the inflation metal tube in the technique scheme.

Compared with prior art, metal tube of the present utility model has following beneficial effect: the pipe thickness of (1) the utility model metal tube is 0.5mm～1.5mm, its tube wall is thin, light weight, and owing to can charge into pressurized air in inflation metal tube inside, under this pressurized air effect, the tube wall of body expands to the body outside, the intensity of metal tube is increased, and then prevented the appearance of situations such as this inflation metal tube is thinner because of tube wall, and intensity is low, fragile; (2) inflation metal tube of the present utility model also has multiple advantages such as simple in structure, with low cost.

Description of drawings

Fig. 1 is the perspective view of the utility model inflation metal tube;

Fig. 2 is for using the handlebar perspective view of the bicycle that the utility model metal tube is arranged;

Embodiment

Referring to Fig. 1, the utility model inflation metal tube comprises body 1, and this body 1 sealing is provided with and the inner hollow setting.

The pipe thickness of body 1 of the present utility model is 0.5mm～1.5mm, and described body 1 is provided with charging air inlet 2, and this charging air inlet 2 can be arranged on place, body end, also can be arranged on the side-walls of body; Can charge into pressurized gas to body 1 inside by this charging air inlet 2, because the pipe thickness of the utility model body 1 is thinner, after body 1 inside charges into pressurized gas, pressurized gas can be from its inside applies active force to body 1 lateral direction to the tube wall of body 1, and then make the tube wall of body 1 expand to body 1 outside, the intensity of metal tube is increased, prevent that metal tube from damaging under external force.

The utility model can be used on the vehicle frame of bicycle, and the metal tube of this cycle frame is made by metal tube of the present utility model; What need describe is, the vehicle frame of bicycle comprises bicycle positions such as handlebar, car front fork, and wherein, the handlebar 3 of using the bicycle that the utility model metal tube is arranged as shown in Figure 2.Because the vehicle frame of this bicycle adopts is metal tube in the technical solutions of the utility model, and therefore, this vehicle frame has light weight, advantage that cost is low under the intensity situation that is not reducing existing bike metal pipe.

Obviously, inflation metal tube of the present utility model also can be applicable to the table body of desk, the chair body etc. of office seat is located, thereby reaches light weight, advantage that valency is low.

Claims (2)

1. inflate metal tube for one kind, it is characterized in that, the body that comprises sealing and inner hollow, described body is provided with in order to fill the charging air inlet of putting pressurized gas to body inside, the pipe thickness of body is 0.5mm～1.5mm, and the tube wall of described body expands to the body outside under the pressurized gas effect that enters body inside from charging air inlet.

2. inflation metal tube as claimed in claim 1 is characterized in that, described charging air inlet is positioned at the place, end of described body or is positioned at the side-walls of body.
