Abstract

The utility model relates to a telescopic two-section straw, which comprises an inserting straw and a sucking straw. The inserting straw can be contained in the sucking straw, an anti-off protruding ring is arranged on the inner side of the upper end of the sucking straw, the inner diameter of the anti-off protruding ring is smaller than the outer diameter of the top of the inserting straw, the lower portion of the sucking straw is in an inverted cone frustum shape, and the inserting straw is in the shape of a straight cylinder. The telescopic two-section straw is applicable to having various diameters, can be straight or bendable in implementation, and has the advantages of novel structure, and convenience and reliability in use.

Description

A kind of scalable two-part suction pipe

Technical field

The utility model relates to a kind of suction pipe, specifically is a kind of scalable two-part suction pipe.

Background technology

In the Food & Drink industry, the use of suction pipe is very extensive, and all internal or external on some product solds have a suction pipe; For suction pipe can exhaust the drink in the container package, thereby the length of suction pipe is longer than container height usually, so in order not make suction pipe take the space of packing; Suction pipe adopts flexible suction pipe usually, and more general suction pipe is wanted many one procedure in packaging step like this, and efficient is lower; Also occur some telescopic pipets on the market, this telescopic pipet is made up of interior pipe and outer tube for this reason, and the inboard of the end outside and interior pipe lower end is provided with screw thread or the boss that matches on inner pipe; The thinner suction pipe of the general use of present this telescopic pipet; Result of use is not good on the big suction pipe of diameter, when stretching, need control dynamics, easily interior pipe is pulled out from outer tube inside; Or the automatic contraction of meeting is gone back and influenced use when sucking, thereby before sucking the heavy caliber Suctorida of milk tea and so on drink, adopt original flexible suction pipe mostly.

Summary of the invention

The purpose of the utility model is to provide a kind of scalable suction pipe, and this suction pipe is applicable to all size diameter suction pipe, and both can on direct suction, implement, and also can on flexible suction pipe, implement, and has novel structure, easy to use and reliable characteristics.

For realizing that above-mentioned purpose adopts following technical scheme:

A kind of scalable two-part suction pipe; Comprise and insert pipe and inhale fair pipe; Insert and manage and can ccontainingly permit in the pipe with suction, it is characterized in that: permit the inboard of the upper end of pipe to be provided with the anticreep bulge loop in described suction, anticreep bulge loop internal diameter is managed the external diameter at top less than insertion; The bottom of the fair pipe of described suction is set up reverse frustoconic, described insertion Guan Weizhi tubular.

Also be configured on the top of described insertion pipe and inhale the reverse frustoconic that fair pipe bottom cooperates.

Middle part at the fair pipe of described suction is provided with threaded area.

Described threaded area is scalable, and the back that stretches is inhaled and permitted length of tube greater than inserting pipe, and threaded area is shunk the length of the fair pipe of back suction then less than inserting pipe.

The utility model is provided with anticreep bulge loop and rounding platform respectively in the fair pipe of suction top and the bottom, and the internal diameter of anticreep bulge loop is less than the external diameter that inserts pipe; Can play preventing to insert pipe and break away from from inhaling fair pipe people, and the reverse frustoconic of bottom cooperates with straight-cylindrical insertion pipe when pipe stretches closelyr inserting, and has better sealing, leak preventing effect is better.

The specific embodiment

Shown in Fig. 1-6; A kind of scalable two-part suction pipe; Comprise and insert pipe 2 and inhale fair pipe 1, insert pipe 2 can be ccontaining with inhale in the fair pipe 1, be provided with anticreep bulge loop 11 in the inboard of the upper end of the fair pipe 1 of described suction; Anticreep bulge loop 11 internal diameters are less than the external diameter that inserts pipe 2 tops, and the bottom of the fair pipe 1 of described suction is set up reverse frustoconic 12; Described insertion pipe 2 is straight tubular, also is configured on the top of inserting pipe and inhales the fair reverse frustoconic 12 that 1 bottom cooperates of managing,

The utility model is provided with anticreep bulge loop 11 and reverse frustoconic 12 respectively in the top and the bottom of inhaling fair pipe; Anticreep bulge loop 11 can both play with reverse frustoconic 12 and prevent to insert the purpose that pipe breaks away from; Reverse frustoconic cooperates with the reverse frustoconic that inserts pipe top and can play better sealing in addition, prevents that structure from leaking gas and influence the result of use of suction pipe.

The utility model also is provided with threaded area 13 in the centre of inhaling fair pipe 1; The length of threaded area bending adjustable pipette; Described threaded area is scalable, and the back that stretches is inhaled and permitted length of tube greater than inserting pipe, and threaded area is shunk the length of the fair pipe of back suction then less than inserting pipe; Shrink to insert length of tube when inhaling fair pipe when threaded area, when using suction pipe, can conveniently come out from inhaling the in-draw of fair pipe inserting the visitor.

The existing relatively telescopic pipet of the utility model, wherein the interface arrangment between pipe and the last pipe is more reliable down, and it is all suitable to be fit to big small-bore suction pipe; Has damping at telescopic process; Can be not up and down, the packing of product is put convenient, and has improved production efficiency.
