Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1: referring to fig. 1-3, the present invention provides a technical solution of a double-step telescopic paper straw: the double-step telescopic paper drinking straw, including the outer tube 1 and the inner tube 2, for the existing telescopic drinking straw, the general structure is almost as much as the existing telescopic drinking straw, and the inner tube is pulled out from the outer tube when in use, but, unlike the plastic telescopic drinking straw, because of the material properties of the paper drinking straw, the user has many problems, one of which is that, after the paper drinking straw is immersed in liquid for a long time, the inner tube is easy to retract, causing inconvenience to the user, or even being completely unusable, therefore, the applicant has developed the structure of the present application to solve the problem, and through research, the applicant has found that the problem is caused by the fact that the inner tube and the outer tube are nested, and the gap is formed between the inner tube and the outer tube, so once the inner tube and the outer tube are immersed in liquid, the initial stage is good, and once the time is long, the liquid entering from the gap can enter the inner pipe and the outer pipe from the inner direction and the outer direction, the paper suction pipe is easy to soften due to the material characteristics, the limit relation between the inner pipe and the outer pipe is invalid, and the inner pipe is retracted into the outer pipe, so that the applicant changes the structure of the original inner pipe and the outer pipe.
Specifically; the outer pipe comprises a main outer pipe 101, a first contracted outer pipe 102 connected with the main outer pipe 101, a second contracted outer pipe 103 connected with the first contracted outer pipe 102, a main through hole 104 arranged in the main outer pipe 101, a contracted extrusion hole 105 arranged in the first contracted outer pipe 102 and an end guide hole 107 arranged in the second contracted outer pipe 103 and communicated with the contracted extrusion hole 105; the inner pipe 2 comprises an inner insertion pipe 201 in clearance fit with the end guide hole 107 and an inner end extrusion pipe 202 connected with the inner insertion pipe 201, the inner end extrusion pipe 202 is connected with the contraction extrusion hole 105 in an interference fit manner, and preferentially, the interference of fit between the inner end extrusion pipe 202 and the contraction extrusion hole 105 is 0.06-0.1 mm. Thus, when the inner end part extrusion pipe 202 is connected with the contraction extrusion hole, the joint part is in interference fit, so that a good sealing effect is achieved, the limit failure caused by liquid permeating into the joint part is avoided, and the limit of the whole straw is effectively ensured.
Further, the method comprises the following steps of; the inner end squeeze tube 202 is in clearance fit connection with the main through bore 104.
Further, in order to better play a role of limiting and prevent the problems caused by the failure of the straw limiting, we further improve that the hole wall of the shrinkage extrusion hole 105 is bent inwards to form an inner pipe spiral protrusion 1061; the inner end portion extrusion pipe 202 includes a front extrusion seal pipe 2021, a rear extrusion seal pipe 2022, and a middle extrusion seal pipe 2023 connecting the front extrusion seal pipe 2021 and the rear extrusion seal pipe 2022, a pipe wall of the middle extrusion seal pipe 2023 is bent inward to form an outer pipe spiral groove 2024, and the outer diameters of the front extrusion seal pipe 2021, the rear extrusion seal pipe 2022, and the middle extrusion seal pipe 2023 are equal. By adopting the structure, when the inner end part extrusion pipe 202 is connected with the contraction extrusion hole, the combination part is also divided into two interference fit sealing parts matched with the front extrusion sealing pipe, the rear extrusion sealing pipe and the contraction extrusion hole on the basis of interference fit, and a middle limiting part formed by the spiral groove of the outer pipe and the spiral bulge of the inner pipe; the two interference fit sealing parts are separated by the middle limiting part, and in the structure, even if one interference fit sealing part is penetrated by liquid, the liquid is rapidly dispersed instead of being concentrated at a certain position due to the structural characteristic of the spiral groove after the liquid is immersed in the middle limiting part, so that the limiting performance is improved.
Further, the method comprises the following steps of; when the outer tube spiral groove 2024 is located in the inner tube spiral protrusion 1061, a head space 3 is formed between the outer tube spiral groove 2024 and the inner tube spiral protrusion 1061, and the head space is more favorable for the dispersion of the liquid.
Further, the method comprises the following steps of; the length of the outer tube spiral groove 2024 is 1/3-1/4 of the length of the inner end pressing tube 202.
Further, a final stop 106 is provided at the end of the main outer pipe 101, which is formed by inwardly contracting or bending, and the final stop can prevent the inner pipe from being removed from the end of the main outer pipe.
Example 2: as shown in fig. 4 and 5, the outer tube 1 further has a body interference portion for preventing the inner tube 2 from being withdrawn. The interference part of the outer tube 1 comprises an outer tube slot 108 and an inner inclined tube wall 109, the outer tube slot 108 is a through hole penetrating through the wall of the outer tube 1, and the inner inclined tube wall 109 is an inclined plane plate extending from the edge of the outer tube slot 108 far away from one side of the inner tube 2 inwards and gradually close to the inner tube 2.
The interference portion of the outer tube 1 further comprises a pulling plate 110 for pulling out the inner chute wall 109. The pulling plate 110 is a flat plate extending obliquely from the outer surface of the inner sloped tube wall 109 to the edge of the outer tube slot 108 on the side closer to the inner tube 2.
The pulling plate 110 is provided with plate stripes, and the plate stripes are straight grooves distributed at intervals along the extending direction of the pulling plate 110.
The pulling plate 110 is provided with a climbing plate 111, and the climbing plate 111 is an arc-shaped panel which is bent and extended from the outer edge of the pulling plate 110 to the surface of the outer pipe 1. The edge-climbing plate 111 prevents the pulling plate 110 from being accidentally moved into the outer tube 1 when the pulling plate 110 is operated, and prevents the fluid from flowing out of the gap between the outer tube slit 108 and the inner-angled tube wall 109 when the fluid is sucked by the suction tube.
