Abstract

The utility model discloses a straw comprising an inner tube and an outer tube sleeved outside the inner tube, wherein the lower end of the outer tube indents inward and is provided at least one groove, and a protruding block is formed on the inner wall, corresponding to the groove, of the outer tube and can abut against the top of the inner tube to prevent the inner tube from contracting into the outer tube. The straw has the advantages of being simple in structure, low in cost and convenient to use due to the fact that the protruding block formed on the inner wall, corresponding to the groove, of the outer tube, can abut against the top of the inner tube to prevent the inner tube from contracting into the outer tube, and prevents the inner tube from contracting inward to the outer tube due to external force.

Description

A kind of suction pipe

Technical field

The utility model relates to a kind of suction pipe.

Background technology

Generally adopt at present suction pipe as the instrument of beverage from container, glass, plastic cup.Present straw is of all kinds, but each Telescopic of a part of suction pipe takes up room.Although perhaps have Telescopic, when using, running into a little external force can shrink back, and the beverage or the suction pipe that cause reaching the bottom drop in beverage bottle, bring inconvenience to use, and be also unhygienic.Perhaps have Telescopic, but complex structure, cost are high.

The utility model content

The utility model provides a kind of suction pipe, and it has overcome the existing deficiency of background technology.The technical scheme that adopts that the utility model solves its technical problem is: a kind of suction pipe, it is characterized in that: it comprises that an inner tube (100) and is socketed in the outer outer tube (200) of inner tube (100), hold at least one groove (210) that sets to the concave under the described outer tube (200), the top of wall respective slot place formation one energy contact inner tube (100) prevents the projection in inner tube (100) the indentation outer tube within the described outer tube.

Among one preferred embodiment: described groove (210) number is made as two and along outer axial tube to symmetry.

Among one preferred embodiment: the caliber of described inner tube (100) is less than the caliber of outer tube (200), and inner tube (100) upper end and outer tube (200) bottom are tight fit.

Among one preferred embodiment: the caliber of described inner tube (100) upper end is little for gradual change from top to bottom, and the caliber of described outer tube (200) bottom is large for gradual change from top to bottom.

Among one preferred embodiment: the end is provided with a threaded portion (220) on the described outer tube (200).

Among one preferred embodiment: mouth of pipe plane of living in, described inner tube (100) lower end is an inclined-plane.

The technical program is compared with background technology, and it has following advantage:

1. the top of the projection energy contact inner tube that wall respective slot place forms within the described outer tube prevents that in the inner tube indentation outer tube, so that this inner tube can not inside contract to outer tube owing to being subject to external force, simple in structure, cost is low, and easy to use.

2. the groove number is made as two and along outer axial tube to symmetry, to the good fixing effect of inner tube.

3. the caliber of inner tube upper end is little for gradual change from top to bottom, and the caliber of outer tube bottom further is fixed inner tube for gradual change from top to bottom is large.

4. the end is provided with a threaded portion on the outer tube, so that flexible being convenient to of this outer tube sucked.

5. mouth of pipe plane of living in inner tube lower end is an inclined-plane, can puncture the thin type beverage cup lid, conveniently sucks.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 has illustrated the perspective exploded view of a kind of suction pipe of a preferred embodiment.

Fig. 2 has illustrated the assembling schematic diagram of a kind of suction pipe of a preferred embodiment.

Fig. 3 has illustrated the use view of a kind of suction pipe of a preferred embodiment.

The specific embodiment

Please refer to Fig. 1 to Fig. 3, an a kind of preferred embodiment of suction pipe, described a kind of suction pipe, it comprises an inner tube 100 and an outer tube 200.

Described outer tube 200 is socketed in outside the inner tube 100.In the present embodiment, the end is provided with a threaded portion 220 on the described outer tube 200, hold at least one groove 210 that sets to the concave under the outer tube 200, the top of wall respective slot place formation one energy contact inner tube 100 prevents the projection in the inner tube 100 indentation outer tubes within the described outer tube, so that this inner tube can not inside contract to outer tube owing to being subject to external force, simple in structure, cost is low, and easy to use.

In the present embodiment, described groove 210 numbers are made as two and along outer axial tube to symmetry.

In the present embodiment, the caliber of described inner tube 100 is less than the caliber of outer tube 200, and inner tube 100 upper ends and outer tube 200 bottoms are tight fit.

Best, the caliber of described inner tube 100 upper ends is little for gradual change from top to bottom, and the caliber of described outer tube 200 bottoms is large for gradual change from top to bottom.

In the present embodiment, described inner tube 100 lower end mouths of pipe plane of living in is an inclined-plane.Mouth of pipe plane of living in inner tube lower end is an inclined-plane, can puncture the thin type beverage cup lid, conveniently sucks.Best, inner tube 100 Length Ratio outer tubes 200 length are slightly long.

When not using suction pipe, inner tube 100 is enclosed within the outer tube 200, and the mouth of pipe of inner tube lower end stretches out outer tube slightly.When needing to use suction pipe, spur inner tube 100 downwards, until the top contact of inner tube 100 is at two projections, so that inner tube 100 can not arbitrarily be retracted.

The above, it only is the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
