See Fig. 1, the stero exploded view of suction pipe, in the figure 10 be outer tube; 11 for the portion that dwindles of outer tube; 20 is suction pipe; 30 are flexible coiled pipe; 31 is socket.By shown in Figure 1, the utility model composite extendible suction pipe is by suction pipe 20; Flexible coiled pipe 30 and outer tube 10 are formed.Wherein, suction pipe 20 can be made the straight tube of a hollow by hard PP (polypropylene) material, flexible coiled pipe 30 can be made the pattern of a most continuous ring-type by elasticity PE (polyethylene) material, its top form can with the socket 31 of suction pipe 20 end fits, and flexible coiled pipe 30 is only on the top, the bottom surface forms opening, and peripheral position all is closed state, and the body of portion 11 is dwindled in its upper end formation one of this outer tube 10, can be inserted in and only make suction pipe 20 to stretch out by outer tube 10 bottoms for suction pipe 20 and flexible coiled pipe 30 by the upper end, and should flexible coiled pipe 30 in stretched condition down outside the footpath be slightly less than footpath within the outer tube 10.

After above-mentioned structure spare made up mutually, see shown in Figure 3, be not subjected to as yet when suction pipe 20 under the pressure of external force, nationality is riddled in the whole outer tube 10 by flexible coiled pipe 30 extension elasticity own, when flexible coiled pipe 30 extruding of order relatively are compressive state, and when making flexible coiled pipe 30 after compression, be 1/3rd length, should stretch coiled pipe 30 after compression, its outer ring surface is also expanded slightly and is made that wall is the state that reclines slightly closely within the outer tube 10, so far, can make outer tube 10 reach suitable location and non-reason is transported and caused rocking arbitrarily during the liquid or displacement up and down.And when power effect outside the suction pipe 20 disappeared, the recovery elasticity of can nationality flexible coiled pipe 30 itself relatively made suction pipe 20 stretch out outwardly and recover state as Fig. 3.

See shown in Figure 4, the utility model composite extendible suction pipe directly can be pushed through high-temperature sterilization and be packaged between tank body 70 and the spiral cover 71, and be under the state of extruding at flexible coiled pipe 30, only make each adjacent ring part compression, so the problem of blocking mutually and hindering elasticity is not arranged, and when taking out (seeing shown in Figure 5) in the spiral cover 71, get final product the elastic stretch effect of the aforementioned flexible coiled pipe 30 of nationality and suction pipe 20 is stretched out automatically outwardly, the effect of being convenient to draw internal beverage is provided according to this, as a same reason, use in the tank body of the utility model applicable to pop can shown in Figure 6.

Under the overhanging state of above-mentioned suction pipe shown in Figure 3 20, there is no any opening owing to be located at the outer ring surface of the flexible coiled pipe 30 of outer tube 10 inside, and its bottom more the position on the position of outer tube 10 lowermost ends, therefore, the utility model overcome existing telescopic pipet derive because of aperture position is too high gas leakage with the not good shortcoming of airtight effect, this composite extendible suction pipe provides the preferable effect of sucking.

Advantage of the present utility model and effect are:

Referring to shown in Figure 4, under the compressive state that is for telescopic pipet, also nationality expand slightly by flexible coiled pipe 30 external diameters and and 10 of outer tubes obtain under the effect of the preferable location that recline, more can solve the problem that outer tube 10 teetertotters arbitrarily or is shifted during transporting, also can reach the effect that makes outer tube 10 suitable location.Obviously, the innovation and creation of the utility model, not only from the textural product that is different from prior art, what is more important is because its ingenious design, and the flexible coiled pipe of configuration particularly, seals at its elasticity, not only provides and sucks effect smoothly; Good airtight air tight effect is more arranged, make outer tube need not all can to obtain suitable positioning action under any fastening step.In addition, the utility model can adopt the material of acid and alkali-resistance, and the advantage of durable preservation is arranged.
