Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral straws, specifically to a bamboo-joint-inspired spiral straw. Background Technology
[0002] A spiral straw is a specially designed straw, its core feature being a spiral pattern on its inner or outer wall. This pattern increases friction to aid in sucking up beverages containing solid particles (such as juice ice cubes, milk tea tapioca pearls, fruit pieces, etc.), preventing the particles from clogging the straw. However, existing spiral straws have a fixed length, making them unsuitable for various applications. Therefore, those skilled in the art have developed a bamboo-joint-inspired spiral straw to address the problems mentioned in the background section. Utility Model Content
[0003] To solve the above technical problems, this utility model provides a bamboo-like spiral straw, including a straight tube body, a fixed spiral tube body installed at the lower end of the straight tube body, an extended spiral tube body provided at one end of the fixed spiral tube body, a square groove opened at one end of both the fixed spiral tube body and the extended spiral tube body, and a square block installed at the other end of the extended spiral tube body, with a round hole opened inside the square block.
[0004] A fixing ring is installed at one end of both the fixed spiral tube and the extended spiral tube. A rotating ring is rotatably connected to the outer surface of the other end of the extended spiral tube. An annular groove is opened at the lower end of the fixing ring. Grooves are symmetrically opened at the lower end of the fixing ring and the grooves are connected to the annular groove. Snap holes are symmetrically opened on the side of the fixing ring and the snap holes are connected to the annular groove. A snap-fit mechanism is symmetrically installed at the upper end of the rotating ring.
[0005] Preferably, several bamboo-like rings are installed on the outer surface of the straight tube, the fixed spiral tube, and the extended spiral tube.
[0006] Preferably, the groove and the card hole are in a cross shape.
[0007] Preferably, the locking mechanism includes a hollow block and a locking block. A movable block is slidably connected inside the hollow block. A spring is symmetrically installed at one inner end of the movable block, and a locking block is installed at one outer end of the movable block, with the locking block passing through the hollow block.
[0008] Preferably, limiting blocks are symmetrically installed on the inner wall of the hollow block, and the limiting blocks pass through the moving block.
[0009] Preferably, the end face of the card block in the counterclockwise direction is an inclined surface.
[0010] The technical effects and advantages of this utility model are as follows:
[0011] This invention allows multiple extension spiral tubes to be installed at the lower end of the fixed spiral tube according to usage requirements, thereby extending the overall length of the spiral straw. It is highly adaptable and easy to use. At the same time, several bamboo-joint-like rings are used to decorate the straight tube, the fixed spiral tube, and the extension spiral tube, improving the aesthetics of the spiral straw.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0020] Please see Figures 1-4This embodiment provides a bamboo-like spiral straw, including a straight tube body 1. A fixed spiral tube body 2 is installed at the lower end of the straight tube body 1. An extended spiral tube body 3 is provided at one end of the fixed spiral tube body 2. Several bamboo-like rings are installed on the outer surfaces of the straight tube body 1, the fixed spiral tube body 2, and the extended spiral tube body 3. A square groove 4 is opened at one end of the fixed spiral tube body 2 and the extended spiral tube body 3. A square block 5 is installed at the other end of the extended spiral tube body 3. A round hole 6 is opened inside the square block 5. A fixing ring 7 is installed at one end of the fixed spiral tube body 2 and the extended spiral tube body 3. A rotating ring 11 is rotatably connected to the outer surface of the other end of the extended spiral tube body 3. An annular groove 8 is opened at the lower end of the fixing ring 7. The fixed ring 7 has symmetrical grooves 9 at its lower end, and the grooves 9 are connected to the annular groove 8. The fixed ring 7 has symmetrical locking holes 10 on its side, and the locking holes 10 are connected to the annular groove 8. The grooves 9 and locking holes 10 are in a cross shape. The rotating ring 11 has a locking mechanism 12 symmetrically installed on its upper end. The locking mechanism 12 includes a hollow block 13 and a locking block 17. The hollow block 13 is slidably connected to a moving block 14. The inner wall of the hollow block 13 is symmetrically fitted with a limiting block 15, and the limiting block 15 passes through the moving block 14. The moving block 14 has a spring 16 symmetrically installed on its inner end. The moving block 14 has a locking block 17 installed on its outer end, and the locking block 17 passes through the hollow block 13. The counterclockwise end face of the locking block 17 is a bevel.
[0021] The working principle of this utility model is as follows: Select multiple extended spiral tubes 3 according to the usage requirements and install them at the lower end of the fixed spiral tube 2. Insert the square block 5 into the square groove 4. At the same time, insert the snap-fit mechanism 12 into the annular groove 8 and the groove 9. Then, rotate the rotating ring 11 counterclockwise by 90 degrees. The rotating ring 11 drives the two snap-fit mechanisms 12 to rotate counterclockwise, so that the inclined surface of the snap-fit block 17 contacts the inner wall of the groove 9. The snap-fit block 17 is pushed into the hollow block 13. At the same time, the snap-fit block 17 pushes the moving block 14 to move and compress the spring 16. The snap-fit mechanism 12 rotates counterclockwise by 90 degrees, so that the snap-fit block 17 corresponds to the position of the snap-fit hole 10. The snap-fit block 17 loses its limiting force. The spring 16 pushes the moving block 14 to reset. The moving block 14 drives the snap-fit block 17 to be inserted into the snap-fit hole 10, thereby connecting the fixed spiral tube 2 and one extended spiral tube 3 together, and connecting several extended spiral tubes 3 together.
