Description

Technical Field

[0001] This utility model relates to the field of silicone tube technology, specifically to a silicone tube that is easy to install. Background Technology

[0002] In industrial production and material handling, silicone tubing is widely used in conveying systems for various materials such as powders, liquids, and granules due to its excellent chemical stability, wear resistance, and non-toxic and odorless properties. However, existing silicone tubing connection and installation methods have many problems, seriously affecting the efficiency and safety of material conveying.

[0003] Currently, the main connection methods for silicone tubing used in material conveying include adhesive bonding, clamp fastening, and direct insertion. Adhesive bonding requires a long curing time, resulting in low installation efficiency. Furthermore, during material conveying, the adhesive may dissolve or detach upon contact with the material, contaminating it. Direct insertion lacks effective positioning and anti-detachment structures. During material conveying, the silicone tubing is prone to loosening or even detachment due to the impact force and vibration generated by material flow, as well as changes in internal pipe pressure, leading to material conveying interruptions and affecting production continuity.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, this utility model provides an easy-to-install silicone tube, whose structure mainly consists of a tube body 1 and a hollow connector 2. By simultaneously optimizing the structure of the tube body 1 and the connector 2, the effect of easy installation during use is achieved. In use, the tube body 1 and the connector 2 can be sequentially spliced ​​together for extended use.

[0027] Both ends of the tube body 1 are coaxially provided with insertion parts 101. The outer diameter of the insertion part 101 is smaller than the outer diameter of the tube body 1. This structural design facilitates the connection between the insertion part 101 and the connector 2.

[0028] On the outer side of the insertion portion 101, a first annular magnetic block 102 and several annular bodies 103 are coaxially arranged. The first annular magnetic block 102 is embedded in the end of the insertion portion 101 near the opening of the tube body 1. In actual production, the first annular magnetic block 102 can be pre-placed in the corresponding position of the mold by injection molding, and then silicone material is injected to make the first annular magnetic block 102 firmly embedded in the insertion portion 101. The annular bodies 103 are distributed at intervals along the axial direction of the insertion portion 101. The annular bodies 103 can be integrally formed using a specific mold structure during the silicone tube molding process, and their spacing is designed according to actual usage requirements and connection stability requirements.

[0029] The connector 2 has annular grooves 201 at both ends that mate with the insertion part 101. A second annular magnet 202 and several annular slots 203 are coaxially arranged on the inner wall of the annular groove 201. The second annular magnet 202 is embedded in the end of the annular groove 201 away from the opening of the connector 2, forming a magnetic connection with the first annular magnet 102. The second annular magnet 202 can also be installed using the same embedding method as the first annular magnet 102. During actual assembly, the insertion part 101 of the tube body 1 is aligned with the annular groove 201 of the connector 2 and inserted. The first annular magnet 102 and the second annular magnet 202 will attract each other under magnetic force and be fixed, reducing installation difficulty. Simultaneously, the annular slots 203 and the annular body 103 form a snap-fit ​​engagement, further enhancing the stability of the connection and preventing the tube body 1 from falling off the connector 2 during use.

[0030] For connector 2, an anti-slip part 205 is provided on the outer side of connector 2. This structural design makes it easy for operators to hold and fix it during installation, so as to adjust the connection angle and position of pipe body 1, and improve the convenience and flexibility of installation.

[0031] The first annular magnetic block 102 and the second annular magnetic block 202 are neodymium iron boron permanent magnets. Neodymium iron boron permanent magnets are characterized by high remanence, high coercivity, and high energy product, providing strong and stable magnetic attraction to ensure the magnetic connection between the tube body 1 and the connector 2. Furthermore, the contact surfaces of the first annular magnetic block 102 and the second annular magnetic block 202 are respectively provided with anti-slip textures, which can be manufactured by machining or molding. The presence of anti-slip textures increases the friction between the contact surfaces of the two magnetic blocks, preventing relative sliding between them under external force, further improving the reliability of the connection.

[0032] To ensure the sealing of the connection, an annular sealing ring 3 is provided at the bottom of the annular groove 201. During installation, when the insertion part 101 is inserted into the annular groove 201, the insertion part 101 and the annular groove 201 are sealed by the annular sealing ring 3. The annular sealing ring 3 can be made of rubber material compatible with silicone tubing. Under compression, the annular sealing ring 3 will undergo elastic deformation, filling the gap between the insertion part 101 and the annular groove 201, effectively preventing leakage of liquids, gases, and other media. It is suitable for various working environments requiring sealed connections, such as liquid transportation pipelines and gas transmission pipelines.

[0033] The inner wall of the annular groove 201 is provided with an inclined surface 204 extending toward the end face of the connector 2. The inner diameter of the inclined surface 204 gradually decreases along the depth direction of the annular groove 201. This design of the inclined surface 204 enables the insertion part 101 to play a guiding role when inserted into the annular groove 201, which facilitates quick alignment and insertion, reduces installation difficulty, and improves installation efficiency.

[0034] In addition, a polyester fiber reinforcement layer 4 and a protective layer 5 are sequentially provided on the outer side of the tube body 1. The polyester fiber reinforcement layer 4 is wrapped around the outer side of the tube body 1 by winding or braiding. Polyester fibers have high strength and high modulus, which can effectively enhance the overall strength and pressure resistance of the silicone tube, preventing deformation and cracking of the silicone tube under large pressure or external force. The protective layer 5 can be made of wear-resistant and corrosion-resistant materials, such as polytetrafluoroethylene, and is covered on the outer side of the polyester fiber reinforcement layer 4 by coating or hot pressing. The protective layer 5 can protect the internal silicone tube and the polyester fiber reinforcement layer 4 from the effects of external environmental factors (such as chemical corrosion, mechanical wear, etc.), extending the service life of the silicone tube and making it suitable for more complex and harsh working environments.

[0035] In practical applications, when assembling silicone tubes, firstly, the annular sealing ring 3 is installed at the bottom of the annular groove 201 of the connector 2. Then, the insertion part 101 of the tube body 1 is aligned with the annular groove 201. Under the magnetic attraction of the first annular magnet 102 and the second annular magnet 202, they are connected and fixed. At the same time, the annular body 103 and the annular slot 203 achieve a snap-fit ​​engagement. After completing the connection of one tube body 1 to the connector 2, the other tube body 1 is connected to the other end of the connector 2 in the same way, thus quickly and conveniently completing the assembly of the silicone tube. During disassembly, only the snap-fit ​​force between the annular slot 203 and the annular body 103 and the magnetic force of the first annular magnet 102 and the second annular magnet 202 need to be overcome to separate the tube body 1 from the connector 2. The operation is simple and convenient.

[0036] Compared to traditional technologies, the silicone tube provided in this technical solution can be automatically attracted to the first annular magnetic block 102 of the tube body 1 insertion part 101 and the second annular magnetic block 202 of the connector 2. During insertion, precise alignment is not required for rapid guidance and positioning, reducing installation time. The annular body 103 of the insertion part 101 and the annular groove 203 of the connector 2 form a snap-fit ​​connection, achieving fixation without tools. Furthermore, multiple sets of annular bodies 103 and grooves 203 are spaced apart, enhancing connection stability. This design combines magnetic guidance with snap-fit ​​locking, making the installation process time-saving and labor-saving while ensuring a firm connection, effectively improving installation efficiency and reliability.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
