Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Embodiment 1, as shown in fig. 1, fig. 2, fig. 4, a straw, wherein, including outer tube and inner tube, outer tube and inner tube are the cavity pipe, the outer tube includes outer tubule 1 and outer tubule 2, the inner tube includes interior tubule 3 and interior tubule 4, still include extrusion contact portion, extrusion contact portion includes outer flared tube 5 and interior flared tube 6, outer flared tube 5 is for connecting outer tubule 2 and outer tubule 1, the diameter is from the pipe of outer tubule 2 to the gradual grow of outer tubule 1, interior flared tube 6 is for connecting interior tubule 4 and interior tubule 3, the diameter is from the pipe of interior tubule 4 to the gradual grow of interior tubule 3. If in will inserting the outer tube with the inner tube, then, the diameter of outer thick pipe 1 is greater than outer tubule 2, and the diameter of interior thick pipe 3 is greater than outer tubule 2 and is less than the diameter of outer thick pipe 1, and the diameter of interior tubule 4 is less than the diameter of outer tubule 2, and like this, after the outer tube was inserted to the inner tube, interior tubule 4 can stretch out outside outer tubule 2 and outer tubule 2 can conflict interior thick pipe 3, avoids the inner tube to break away from. The inner tube and the outer tube can be hugged closely each other through extrusion contact portion, specifically, after interior tubule 4 stretches out outer tubule 2, outer flaring pipe 5 can be pressed close to gradually to interior flaring pipe 6, and after the surface of interior flaring pipe 6 pasted to the internal surface of outer flaring pipe 5 completely, again with interior tubule 4 stretch out outer tubule 2 the words, flaring pipe 6 in outer flaring pipe 5 can extrude for the connection of the two becomes more stable, difficult separation. The outer tube has a throat 7 to prevent the inner tube from coming off. The necking part 7 is a cylinder which extends outwards from the edge of the outer thick tube 1 on the side far away from the outer thin tube 2 and has a gradually reduced diameter. The provision of the constricted portion 7 prevents the inner pipe from moving to the outer end of the outer wide pipe 1 and becoming detached.

As shown in fig. 3, a body interference part for preventing the inner tube from being withdrawn is further provided on the outer tube. Pipe shaft conflict portion includes pipe shaft grooving 8 and interior pipe chute wall 9, and pipe shaft grooving 8 is the opening of the pipe wall that runs through outer thick pipe 1, and interior pipe chute wall 9 is the edge of pipe shaft grooving 8 inwards just be close to the inclined plane board that outer tubule 2 extends gradually from keeping away from outer tubule 2 one side. The pipe body cutting groove 8 can be symmetrically arranged on the pipe body of the outer thick pipe 1 by a central shaft, so that the inner inclined pipe walls 9 on two sides can symmetrically resist the edge of the inner thick pipe 3.

The body interference portion also includes a tear panel 10 for pulling the inner tube-chute wall 9 out. The pulling plate 10 is a flat plate extending obliquely from the outer surface of the inner inclined tube wall 9 to the edge of the tube body cutting groove 8 close to the outer thin tube 2. The function of the pulling plate 10 is to make the end of the inner inclined tube wall 9 no longer abut against the edge of the inner thick tube 3 when the inner thin tube 4 needs to be retracted into the outer thin tube 2, specifically, to apply a force on the pulling plate 10 to pull the end edge of the inner inclined tube wall 9 to the outer side of the outer thick tube 1, so that the end edge of the inner inclined tube wall 9 is close to the inner wall of the outer thick tube 1, and the retraction of the inner thick tube 3 is realized. The pulling plate 10 is provided with plate stripes, and the plate stripes are straight grooves distributed at intervals along the extending direction of the pulling plate 10. The extending direction of the straight strip groove is the horizontal direction. The effect of the surface striations is to increase the roughness of the surface of the tear panel 10 so that the force applied to the tear panel 10 is more stable. The edge-climbing plate 11 is arranged on the pulling plate 10, and the edge-climbing plate 11 is an arc-shaped panel which is bent and extended from the outer edge of the pulling plate 10 to the surface of the outer thick pipe 1. The edge-climbing plate 11 can prevent the pulling plate 10 from moving to the inside of the outer thick tube 1 by accident when the pulling plate 10 is operated, and can prevent the fluid from flowing out from the gap between the tube body cutting groove 8 and the inner inclined tube wall 9 when the fluid is sucked by using the suction tube.
