Description

Technical Field

[0001] This utility model relates to the field of plastic straw technology, specifically a detachable plastic straw. Background Technology

[0002] Plastic straws are tubular plastic products widely used in daily life, primarily for drinking beverages. They are widely adopted due to their low cost, ease of production, and convenient use. Since the 1960s, plastic straws have gradually replaced paper straws, becoming an important tool in the food and beverage industry.

[0003] Hardened plastic straws are a type of plastic straw. They are made of plastic and have undergone special processing to increase their hardness. They are pressure-resistant, not easily bent or broken, and can be reused.

[0004] Regarding the above-mentioned technical conditions, there are also drawbacks: after prolonged use, dirt will accumulate on the inner wall of the plastic hardened straw. However, since the plastic hardened straw is a single piece and cannot be disassembled, and because it is relatively thin and long, it is not convenient to clean the inner wall of the plastic hardened straw.

[0005] Based on this, the present invention designs a detachable plastic straw to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a detachable plastic straw to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detachable plastic straw, comprising a hardened plastic straw, the hardened plastic straw comprising a main tube and a secondary tube, the secondary tube being inserted into the main tube, the outer side wall of the secondary tube abutting against the inner side wall of the main tube, a first limiting groove being formed on the inner side wall of the main tube, a second limiting groove being formed on the outer side wall of the secondary tube, the second limiting groove abutting against the first limiting groove, a rubber ring being sleeved on the secondary tube, the rubber ring being sleeved on the main tube, the rubber ring abutting against the outer side wall of the secondary tube, and the rubber ring abutting against the outer side wall of the main tube.

[0008] Preferably, a first sealing groove is provided at the end of the main pipe away from the secondary pipe, and a first sealing ring is fixedly provided on the inner side wall of the rubber ring, with the first sealing ring abutting against the first sealing groove.

[0009] Preferably, a second sealing groove is provided at the end of the secondary pipe away from the main pipe, and a second sealing ring is fixedly provided on the inner side wall of the rubber ring, with the second sealing ring abutting against the second sealing groove.

[0010] Preferably, a positioning strip is fixedly provided in the first limiting groove, and a positioning groove is provided in the second limiting groove, with the positioning strip inserted into the positioning groove.

[0011] Preferably, both ends of the rubber ring are chamfered.

[0012] In summary, this application has the following beneficial technical effects: When cleaning the hardened plastic straw, first remove the rubber ring from the main and secondary tubes of the hardened plastic straw. Because the rubber ring is elastic, forcefully pull the outer wall of the rubber ring to make the first sealing ring leave the first sealing groove and the second sealing ring leave the second sealing groove. Move the rubber ring away from the hardened plastic straw, and the rubber ring is removed from the secondary tube and the main tube. Then, apply an opposite force to the secondary tube and the main tube respectively, and the secondary tube separates from the main tube. At this time, the hardened plastic straw is split into two sections, which facilitates the cleaning of the inner wall of the hardened plastic straw, thus achieving the effect of conveniently cleaning the inner wall of the hardened plastic straw.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] A detachable plastic straw includes a hardened plastic straw, comprising a main tube 1 and a secondary tube 3. The secondary tube 3 is inserted into the main tube 1, with its outer side wall abutting against the inner side wall of the main tube 1. A first limiting groove is formed on the inner side wall of the main tube 1, and a second limiting groove 9 is formed on the outer side wall of the secondary tube 3. The first limiting groove abuts against the second limiting groove 9. With the main tube 1 and secondary tube 3, the hardened plastic straw can be separated into two sections, making it more convenient to clean the inner side wall of the hardened plastic straw.

[0023] A rubber ring 2 is fitted onto the secondary pipe 3, and the rubber ring 2 is fitted onto the main pipe 1. One end of the rubber ring 2 abuts against the outer wall of the secondary pipe 3, and the other end of the rubber ring 2 abuts against the outer wall of the main pipe 1. The rubber ring 2 serves to fix the secondary pipe 3 onto the main pipe 1. At the same time, the rubber ring 2 is elastic and can undergo elastic deformation under force. When the rubber ring 2 is fitted onto the outer walls of the secondary pipe 3 and the main pipe 1 respectively, under the action of elasticity, the inner wall of the rubber ring 2 abuts against the outer walls of the secondary pipe 3 and the main pipe 1 respectively.

[0024] A first sealing groove 6 is provided at the end of the main pipe 1 away from the secondary pipe 3. A first sealing ring 4 is fixedly provided on the inner side wall of the rubber ring 2. The first sealing ring 4 is pressed against the first sealing groove 6. The connection sealing between the rubber ring 2 and the main pipe 1 is increased by the setting of the first sealing ring 4 and the first sealing groove 6.

[0025] A second sealing groove 8 is provided at the end of the secondary pipe 3 away from the main pipe 1. A second sealing ring 5 is fixedly provided on the inner side wall of the rubber ring 2. The second sealing ring 5 is pressed against the second sealing groove 8. The connection sealing between the rubber ring 2 and the main pipe 1 is increased by the provision of the second sealing ring 5 and the second sealing groove 8.

[0026] Multiple positioning strips 10 are fixedly installed in the first limiting groove, and a positioning groove 7 adapted to the positioning strips 10 is installed in the second limiting groove 9. The positioning strips 10 are inserted into the positioning grooves 7. The positioning strips 10 and the positioning grooves 7 are designed to increase the installation stability of the secondary pipe 3 in the main pipe 1, making it difficult for the secondary pipe 3 and the main pipe 1 to rotate relative to each other.

[0027] Both ends of the rubber ring 2 are chamfered. When inserting the hardened plastic straw into a cup or other item, the chamfered rubber ring 2 can reduce the resistance of the rubber ring 2, making it easier to insert the hardened plastic straw into the cup or item.

[0028] The implementation principle of this embodiment is as follows: When cleaning the hardened plastic straw, first remove the rubber ring 2 from the main tube 1 and the secondary tube 3 of the hardened plastic straw. Because the rubber ring 2 is elastic, pull the outer wall of the rubber ring 2 to make the first sealing ring 4 leave the first sealing groove 6 and the second sealing ring 5 leave the second sealing groove 8. Move the rubber ring 2 away from the hardened plastic straw, and the rubber ring 2 is removed from the secondary tube 3 and the main tube 1. Then, apply a force in opposite directions to the secondary tube 3 and the main tube 1 respectively, and the secondary tube 3 separates from the main tube 1. At this time, the hardened plastic straw is split into two sections, which makes it convenient to clean the inner wall of the hardened plastic straw, thus achieving the effect of conveniently cleaning the inner wall of the hardened plastic straw.
