Detailed Description

The embodiment of the application provides a telescopic straw, a first pipe body 1 and a second pipe body 2 are arranged, a sealing end is arranged on the second pipe body 2, and a sealing ring 3 is sleeved on the sealing end to realize the sealing performance of the second pipe body 2 relative to the first pipe body 1 during telescopic movement; the technical problems that the stainless steel suction pipe in the prior art has no telescopic capability and is long in size are solved; the technical effects that the stainless steel suction pipe is telescopic and the sealing performance of the suction pipe is strong are achieved.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Example one

Referring to fig. 1 and 3, a telescopic pipette comprising: first body 1, second body 2 and sealing washer 3. The first pipe body 1 and the second pipe body 2 are both stainless steel pipes, part of the second pipe body 2 penetrates through the first pipe cavity 11, and the sealing ring 3 is attached to the first pipe cavity 11; the seal ring 3 seals the expansion and contraction.

The first tube body 1, have a first lumen 11 in the first tube body 1, first lumen 11 is for running through the form. The first pipe body 1 is provided with a clamping part 12 relative to the sealing end, and the clamping part 12 is arranged at one end of the first pipe body 1; the outer side of the clamping part 12 is arc-shaped.

Referring to fig. 4-5, the second tube 2 has a second tube cavity 21 therein, the second tube cavity 21 is through, and one end of the second tube 2 is provided with a sealing end, and the sealing end and the second tube 2 are integrally designed. The sealing end is positioned in the first tube cavity 11; the sealing end includes a groove 22 and a ridge 23.

A groove 22, the groove 22 being recessed relative to the second body 2.

The convex edge 23 is convex relative to the second pipe body 2, and the convex edge 23 is arranged behind the groove 22. The maximum cross-sectional area of the convex edge 23 is larger than or equal to the maximum cross-sectional area of the sealing ring 3.

The sealing ring 3 is sleeved on the groove 22, and the sealing ring 3 can be a silica gel ring.

The working principle is as follows:

the sealing end of the second pipe body 2 is arranged in the first pipe cavity 11, and the convex edge 23 is used for increasing the friction force between the second pipe body 2 and the first pipe cavity 11, so that the second pipe body 2 is prevented from sliding out of the first pipe cavity 11; the seal 3 is used to seal the first pipe 1 and the second pipe 2.

The technical effects are as follows:

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
