Abstract

A straw, comprising a main tube (1) and two telescopic outer tubes (2). The two telescopic outer tubes (2) are sleeved outside the main tube (1) separately, and can be pulled out outward or retracted inward with respect to the main tube (1); the main tube (1) is connected to the two telescopic outer tubes (2) separately by means of connecting structures. During use of the straw, the length of the straw can be adjusted in real time according to requirements. A protruding tube (3) fits and sleeved to a neck (4). A simple structure is achieved. The protruding tube (3) and the main tube (1) are an integrated structure, and the junction between the protruding tube (3) and the main tube (1) is arc-shaped. The arc shape fits the shape of the neck (4), thereby achieving better sealability. The main tube (1) and the two telescopic outer tubes (2) are both stainless steel tubes. A stainless steel material can be reused. The straw is easy to store and use. The environmental pollution can be effectively reduced, and environmental protection is achieved better. Two outer ends of the two telescopic outer tubes (2) are provided with inward arc-shaped chamfers, and either one of the two ends can be used for sucking, thereby achieving higher safety during sucking of a user.

Description

A straw

Technical field

The invention relates to a straw, in particular to a reusable straw.

Background technique

At present, many food and beverage establishments, such as restaurants, drink shops, canteens, can't do without straws when eating liquid food. However, the straws commonly used in the above places are disposable straws, which waste materials and cannot be reused, generate a large amount of plastic garbage, pollute the environment, and are not conducive to environmental protection, which has brought some impact on our lives. There are also some reusable straws, but they are not retractable and take up a lot of storage space.

Summary of the Invention

The technical problem to be solved by the present invention is to provide a straw, which has a simple structure and good airtightness. The length of the straw can be adjusted in real time according to needs during use, convenient storage, stainless steel materials can be reused, effectively reducing environmental pollution, and more environmentally friendly.

The technical solution adopted by the present invention to solve the technical problem is: a straw, comprising a main pipe and two retractable outer pipes, the two retractable outer pipes are respectively sleeved outside the main pipe, and the two retractable outer pipes are respectively The main pipe can be pulled out or retracted inward relative to the main pipe, and the main pipe and the two retractable outer pipes are respectively connected through a connection structure.

As a kind of preference, the connecting structure is provided with a convex pipe at both ends of the main pipe, and shrinkage ends are respectively provided at the ends of the two telescopic outer pipes and the main pipe, and the inner diameter of the shrinkage pipe and the outer diameter of the main pipe Diameter matching socket, the outer diameter of the convex pipe matches with the inner diameter of the retractable outer pipe.

As a further improvement, the convex pipe and the main pipe are in an integrated structure, and the connection between the convex pipe and the main pipe is arc-shaped, and the arc-shape matches the necked shape.

As a further improvement, inward circular arc chamfers are respectively provided on the outer ends of the two retractable outer tubes.

As a preferred example, the length of the convex tube is 3 to 8 mm.

As a preference, both the main pipe and the two retractable outer pipes are stainless steel pipes.

As a kind of preference, the connecting structure is provided with a convex ring at both ends of the main pipe and a flange at the port, and shrinking ends are respectively provided at the ends where the two retractable outer tubes are sleeved with the main pipe; Convex ring, flanging and main pipe are integrated structure.

The beneficial effect of the invention is that the length of the straw can be adjusted in real time according to needs during use. The convex tube and the necking are matched and sleeved, and the structure is simple. The convex tube and the main pipe are an integrated structure, and the convex tube and the main connection are arc-shaped. It is easy to use and store, which effectively reduces environmental pollution and is more environmentally friendly. In addition, both outer ends of the two retractable outer tubes are provided with inwardly-shaped arc chamfers, and either end can be used as a sucking, which makes the user safer when sucking.
