Description

Technical Field

[0001] This utility model relates to the field of silicone tube technology, specifically to an externally braided silicone tube structure. Background Technology

[0002] Silicone tubing is widely used in electronics, medical, and food processing fields due to its excellent resistance to high and low temperatures, aging resistance, and chemical stability. Traditional silicone tubing is usually made of a single silicone material and is connected to other components through simple splicing or heat fusion. This structure can meet basic media transportation requirements under normal conditions.

[0003] However, existing silicone tubing still has many shortcomings in practical applications. In static-sensitive scenarios, ordinary silicone tubing cannot discharge static electricity generated by friction in a timely manner, lacks an effective anti-static structure, and is prone to dust adsorption or flammability and explosion risks. When the ends of silicone tubing are connected to external equipment, the lack of stable fixing measures makes it easy for edge warping and delamination to occur, resulting in reduced sealing performance and affecting the safety and stability of media transportation. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an externally braided silicone tube structure, which can effectively solve the technical problems of insufficient compressive strength and poor antistatic ability of current silicone tubes.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An externally braided silicone tube structure includes an inner silicone tube, a metal collar, and a hollow metal head.

[0007] The outer side of the silicone inner tube is sequentially covered with an antistatic layer and a braided layer. The metal collar is sleeved on the end of the silicone inner tube and pressed against the outer side of the braided layer for fixation. The outer side of the metal collar is provided with an external thread body. Both ends of the metal head are respectively provided with a slot for embedding and installing the metal collar. The inner wall of the slot is provided with an internal thread body that cooperates with the external thread body for locking and fixing. The outer side of the metal head is provided with a grounding terminal for grounding.

[0008] Furthermore, the antistatic layer and the braided layer are fixed together by a hot melt adhesive.

[0009] Furthermore, the outer side of the braided layer is also covered with a protective layer, the two ends of which are in contact with the ends of the corresponding metal collars.

[0010] Furthermore, the bottom of the slot is provided with a sealing ring that is sealed to a metal collar.

[0011] Furthermore, the outer side of the metal head is provided with an anti-slip part.

[0012] Furthermore, the grounding terminals are circumferentially distributed on the outside of the metal head, and the grounding terminals are provided with wiring holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By sequentially setting an antistatic layer and a braided layer on the outer layer of the silicone inner tube, not only can the static electricity accumulated on the surface of the tube be effectively conducted away, but the overall compressive strength is also enhanced, preventing the silicone tube from deforming due to external pressure. A metal collar is set at the end of the silicone tube, and the metal collar is covered with the braided layer, which can effectively prevent the silicone tube end from warping or delamination. When used with a metal head, it not only ensures a stable connection, but also forms a static discharge path through grounding of the metal head, thus enhancing the antistatic effect.

[0024] 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.

[0025] like Figure 1-5 As shown, this technical solution provides an externally braided silicone tube structure, the core components of which include a silicone inner tube 1, a metal collar 2, and a hollow metal head 3. The silicone inner tube 1 serves as the basic carrier of the entire structure; its material is medical-grade silicone, possessing good flexibility, chemical stability, and biocompatibility, enabling it to adapt to various complex usage environments. An antistatic layer 4 and a braided layer 5 are sequentially wrapped around the outside of the silicone inner tube 1.

[0026] The antistatic layer 4 is made of a composite material of conductive carbon black and silicone. The conductive carbon black is uniformly dispersed in the silicone matrix to form a continuous conductive network, which can quickly conduct away the static electricity generated on the surface of the silicone tube, effectively avoiding the hazards caused by static electricity accumulation, such as static electricity attracting dust and causing electronic equipment malfunctions.

[0027] The antistatic layer 4 and the braided layer 5 are fixed by a hot melt adhesive. The hot melt adhesive is a high-temperature resistant and highly adhesive polyurethane hot melt adhesive. Under heating conditions, the polyurethane hot melt adhesive can quickly melt and penetrate into the surface of the antistatic layer 4 and the braided layer 5. After cooling, it forms a strong bond, ensuring that there is no relative displacement between the two layers and guaranteeing the stability of the overall structure.

[0028] The braided layer 5 is made of high-strength glass fiber filaments. Glass fiber filaments possess high strength and high modulus, significantly improving the pressure resistance of the silicone tubing and making it less prone to deformation under external pressure. Simultaneously, the braided layer 5 also enhances the wear resistance of the silicone tubing, extending its service life.

[0029] Outside the braided layer 5, a protective layer 6 is also provided, made of polyvinyl chloride (PVC). PVC has good wear resistance, corrosion resistance, and weather resistance, effectively protecting the internal braided layer 5 and antistatic layer 4 from damage caused by external environmental factors. The two ends of the protective layer 6 contact the ends of the corresponding metal collars 2, forming a closed protective structure, further enhancing the protective effect.

[0030] A metal collar 2 is fitted onto the end of the silicone inner tube 1 and pressed against the outside of the braided layer 5 for fixation. The metal collar 2 is made of stainless steel. Stainless steel has excellent strength and corrosion resistance, which can firmly fix the silicone inner tube 1 and the braided layer 5, ensuring the connection stability of the entire silicone tube structure. The outer circumferential surface of the metal collar 2 is provided with an external thread 201 for connection and fixation with the hollow metal head 3.

[0031] The hollow metal head 3 has slots 301 at both ends for embedding and installing metal collars 2. This structure allows for the splicing of the silicone inner tube 1. The inner wall of the slot 301 has an internal thread body 302 that engages with the external thread body 201 for locking and fixing. During installation, the metal collar 2 is inserted into the slot 301, and the hollow metal head 3 is rotated to make the internal thread body 302 and the external thread body 201 mesh together, achieving a tight connection. The bottom of the slot 301 has a sealing ring 7 that seals with the metal collar 2. The sealing ring 7 is made of nitrile rubber. Nitrile rubber has good oil resistance, wear resistance, and sealing performance, which can effectively prevent liquids, gases, and other media from leaking from the connection point, ensuring the sealing performance of the silicone tube during the media transportation process.

[0032] The outer side of the metal head 3 is provided with a grounding terminal 303 for grounding. The grounding terminals 303 are circumferentially distributed on the outer side of the metal head 3, and the grounding terminals 303 have wiring holes 305. In practical applications, by passing the grounding wire through the wiring hole 305 and fixing it and connecting it to the grounding terminal 303, the static electricity generated on the silicone tube can be promptly conducted to the ground, further enhancing the anti-static effect.

[0033] In addition, the outer side of the metal head 3 is provided with an anti-slip part 304, which is made by knurling. The knurled texture increases the friction on the surface of the metal head 3, making it easier for operators to install and disassemble.

[0034] In actual production, the silicone inner tube 1 is first prepared by extruding medical-grade silicone into the required specifications. Then, an antistatic layer 4 and a braided layer 5 are sequentially coated onto the outside of the silicone inner tube 1. The antistatic layer 4 is formed by extrusion coating, while the braided layer 5 is made by weaving glass fiber filaments onto the inner tube using a braiding machine. Next, a protective layer 6 is wrapped around the outside of the braided layer 5 using an extrusion coating process. Afterward, a metal collar 2 is fitted onto the end of the silicone inner tube 1, and a dedicated pressing device is used to tightly press and fix the metal collar 2 to the silicone inner tube 1 and the braided layer 5. Finally, the hollow metal head 3 is connected to the metal collar 2 through a slot 301 and tightened, and the sealing ring 7 is installed, completing the assembly of the entire outer braided silicone tube structure.

[0035] Compared with traditional technologies, the silicone tube structure provided by this technical solution, by sequentially setting an antistatic layer 4 and a braided layer 5 on the outer layer of the inner silicone tube 1, can not only effectively conduct away the static electricity accumulated on the surface of the tube, but also enhance the overall compressive strength and prevent the silicone tube from deforming due to external pressure. The end of the silicone tube is provided with a metal collar 2, which is covered with the braided layer 5, which can effectively prevent the silicone tube end from warping and delamination. When used with a metal head 5, it not only ensures a stable connection, but also forms a static discharge path through grounding of the metal head 5, thus enhancing the antistatic effect.

[0036] This structure, through a multi-layered design and the integration of metal components, achieves enhanced performance and practical value: Firstly, the antistatic layer outside the silicone inner tube conducts static electricity, preventing charge accumulation and potential risks, while the braided layer strengthens the tube's compressive strength, preventing deformation due to external pressure. The combination of these two elements improves protective performance. Secondly, the metal collar, fitted over the braided layer at the end, effectively prevents the silicone tube end from warping or delaminating. Its external thread locks into the internal thread of the metal head slot, ensuring a secure connection and creating a static discharge path through the metal head's grounding terminal: "antistatic layer - metal collar - metal head - grounding," further enhancing the antistatic effect. Furthermore, the threaded connection facilitates disassembly and maintenance, and the compatibility between the metal components and the silicone material allows for adaptation to complex working conditions, extending service life.

[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.
