Description

A kind of scalable suction pipe

Technical field

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

Background technology

In the Food ﹠ Drink industry, the use of suction pipe is very extensive, all internal or external on some product solds have a suction pipe, for suction pipe can exhaust 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, more general suction pipe is wanted many procedures in packaging step like this, efficient is lower, some telescopic pipets also appear on the market for this reason, this telescopic pipet is made up of interior pipe and outer tube, 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, need control dynamics when stretching, easily interior pipe is pulled out from outer tube inside or when sucking, can automatically shrink and go back and influence use, 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 this utility model is to provide a kind of scalable suction pipe, and this suction pipe is applicable to all size diameter suction pipe, both can implement on direct suction, also can implement on flexible suction pipe, has novel structure, easy to use and reliable characteristics.

For achieving the above object by the following technical solutions: a kind of scalable suction pipe, comprise top tube and down tube, it is characterized in that: be provided with connecting portion in the described upper end of pipe down, on the outer wall of this connecting portion, be provided with annular boss, between the two ends up and down of annular boss and connecting portion outer wall, form step, the bottom of following pipe is a suction nozzle, is bellows body between suction nozzle and connecting portion; Described lower end of going up pipe is provided with inside flange, above last pipe lower end flange, be provided with boss, spacing is complementary with the annular boss width of following pipe between boss and the flange, the top of pipe also is provided with inside flange on described, and the internal diameter at the described boss of going up pipe and flange place is more less than the external diameter of the annular boss on the following pipe jointing part.

The middle part of pipe is provided with bend on described.

The described upward internal diameter at the flange place of pipe and the external diameter of bellows body are complementary.

The internal diameter at the described upward flange place of pipe is bigger than the external diameter of suction nozzle.

The utility model all is provided with inside flange at the two ends of last pipe, flange will descend pipe jointing part to be limited in the inner feasible pipe down of pipe can't break away from pipe under general situation, and the boss of going up inside pipe wall can match with following pipe jointing part outer wall annular boss and can limit down moving up and down of pipe, the internal diameter at the flange place of bellows body external diameter and last pipe is complementary and can guarantees down that pipe keeps certain damping at telescopic process, can be not up and down, and guarantee sealing between the upper and lower suction pipe.

The structural representation of pipe on Fig. 1, the utility model; The structural representation of pipe under Fig. 2, the utility model; The structural representation of Fig. 3, the utility model extended configuration; The structural representation of Fig. 4, the utility model contraction state; Fig. 5 is the enlarged diagram at A place among Fig. 3; Fig. 6 is the enlarged diagram at B place among Fig. 4; Fig. 7 is the structural representation of upper and lower pipe jointing part.

The specific embodiment

Shown in Fig. 1-7, a kind of scalable suction pipe, comprise pipe 1 and manage 2 down, be provided with connecting portion 21 in the described upper end of pipe 2 down, on the outer wall of this connecting portion 21, be provided with annular boss 22, form step between the two ends up and down of annular boss 22 and connecting portion 21 outer walls, the bottom of following pipe 2 is a suction nozzle 23, is bellows body 24 between suction nozzle 23 and connecting portion; Described lower end of going up pipe 1 is provided with inside flange 11, above last pipe 1 lower end flange 11, be provided with boss 12, spacing is complementary with annular boss 22 width of managing 2 down between boss 12 and the flange 11, the top of pipe 1 also is provided with inside flange 11 on described, the boss 12 of described upward pipe and the internal diameter at flange 11 places are more less than the external diameter of managing 2 connecting portions 21 down, the described upward internal diameter at flange 11 places of pipe 1 and the external diameter of bellows body 24 are complementary, the internal diameter at described flange 11 places of going up pipe 1 is bigger than the external diameter of suction nozzle 23, and the middle part of pipe 1 is provided with bend on described.

As shown in Figure 7, the utility model is on machine during moulding just, on, under manage 1, the 2nd, connect as one, to go up, under manage 1,2 cut off from the scrobicular ring that connects, and will descend pipe 2 to stretch into and firmly break through the flange 11 of managing 1 top from the top of last pipe 1, make that the connecting portion 21 of pipe 2 is contained in pipe 1 inside down, owing to be bellows body 24 in the middle of pipe 2 bodys down, bellows body 24 is complementary with flange 11 sizes of last pipe 1, in managing 2 telescopic process down, certain damping action is arranged, when stretching, more feeling of this spline structure, when the annular boss 22 of managing 2 connecting portion 21 instantly just is between the flange 11 of boss 12 and lower end, annular boss 22 two ends steps match with the boss 12 of last pipe and the flange 11 of lower end, and suction pipe can be brought and suck drink this moment.

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, has improved production efficiency.
