Abstract
The utility model elates to a screw-thread retractable sucker, solving the shortcoming that the retractable sucker of the prior art is easy to retract after pulling, comprising an outer tube which comprises an inner pipe and is sleeved on the inner pipe. The utility model is characterized in that an inner screw thread is positioned on the inner side of the top part of the outer tube; and an outer screw thread matched with the inner screw thread is positioned on the outer side of the bottom part of the inner pipe. The screw-thread retractable sucker has the advantages of simple structure, convenient use, fixed length and no retraction of the sucker after pulling.
Description
Technical field
The utility model relates to a kind of accessory of catering industry, a kind of specifically telescopic pipet that is used for beverage.
Background technology
Box-packed drink is owing to being easy to preservation, easy to carry being loved by the people, subsidiary telescopic pipet is generally telescopic on the box-packed drink, be divided into outer tube and interior pipe, close up at the top of outer tube collar extension during making and dwindle, make it to expand in the bottom of interior pipe, when managing in overcoat, pulling out like this, outer tube separates with interior Guan Buhui, and increased overall pipe range, be convenient to pack and drink, but very easily withdrawing, the interior pipe after this kind connected mode slightly firmly can make and stretch in the outer tube, makes troubles for drinking.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, to provide a kind of stretching back to be difficult for retraction, the screw-type telescopic pipet that can conveniently drink.
The technical solution of the utility model comprises: pipe and on inner pipe outer tube of cover in comprising, be provided with internal thread in described outer tube inside top, interior pipe bottom outside be provided with can with the external screw thread of screw-internal thread fit.
Described outer tube inside top also is provided with elastic seal ring.
By internal thread and externally threaded cooperation, the interior pipe after the stretching is fixedlyed connected with outer tube, keep length constant, the problem of pipe retraction in can not occurring.Good fruit is imitated in the connecting portion sealing of interior pipe after the use elastic seal ring is tightened partial screw threads and outer tube, can not leak gas, and is convenient to smoke.
Description of drawings
Fig. 1 is the structural representation of the utility model contraction state.
Fig. 2 is the structural representation of the utility model extended state.
The specific embodiment
Be further explained explanation below in conjunction with accompanying drawing to this usefulness is novel:
With reference to accompanying drawing: interior pipe 2 is outer to be with outer tube 1, and described outer tube 1 inside top is provided with internal thread 4, described in pipe 2 bottom outside be provided with external screw thread 3, described internal thread 4 can cooperate with external screw thread 3 and screws.Inside top at outer tube 1 also is provided with elastic seal ring 5.
During contraction state: outer tube 1 is enclosed within on most of interior pipe 1; During extended state: interior pipe 2 is outwards pulled out, in after pipe 2 major part pulls out in the outer tube 1, with interior pipe 2 to a sideway swivel, pipe 2 external screw thread 3 can cooperate with the internal thread 4 of outer tube 1 and screws in making, interior pipe 2 and outer tube 1 after the stretching can be maintained fixed, and no longer bounce back, simultaneously, it is close that elastic seal ring 5 is well sealed the cooperation of spiral shell mosquito, is convenient to draw beverage.
