Description

Technical Field

[0001] This application relates to the field of silicon core tubes, and in particular to a pressure-resistant silicon core tube that is easy to connect. Background Technology

[0002] Silicon core pipe is a new type of composite pipe with an inner wall lined with a silica-based solid lubricant. It boasts excellent sealing performance, resistance to chemical corrosion, and low engineering costs, making it widely used in fiber optic cable communication network systems for highways, railways, and other applications. HDPE silicon core pipe, also known simply as silicon pipe, is a new type of composite pipe with an inner wall lined with a silica-based solid lubricant. Its main raw material is high-density polyethylene, and the core layer is made of silica, a solid lubricant with the lowest coefficient of friction. It is widely used in fiber optic cable communication network systems.

[0003] Chinese patent CN221305435U discloses a pressure-resistant silicon core tube for cables that facilitates connection. The tube includes a silicon core tube body, one end of which has an external thread. A first threaded hole is located on one side of the external thread, and several first inserts are connected to one side of the first threaded hole. First insert holes are located between the first inserts, and each first insert has a second threaded hole. A limiting block is connected to the other end of the silicon core tube body. A second insert is connected to one side of the limiting block, and the second insert has a third threaded hole that matches the first threaded hole. A fourth threaded hole that matches the second threaded hole is located on the other side of the limiting block. This silicon core tube allows for quick connection between two silicon core tubes, ensuring a stable connection without detachment. Multiple fixing methods enhance the connection's strength, and the connector is protected by multiple conduits, extending its service life. The overall operation is simple, convenient, and efficient.

[0004] However, the above solution requires multiple bolts to connect the two silicon core tubes. The bolts need to be screwed in manually, which increases the work steps and reduces the connection efficiency. Moreover, the bolts are prone to rust after long-term use, making disassembly difficult. Furthermore, gaps can easily appear between the multiple first and second inserts, allowing external air to enter and affect the internal cables. Utility Model Content

[0005] The existing silicon core tubes require multiple bolts to connect two silicon core tubes, which need to be manually screwed in, increasing the work steps and reducing the connection efficiency. Furthermore, the bolts are prone to rust after long-term use, making disassembly difficult. In addition, gaps can easily appear between the multiple first and second plugs, allowing external air to enter and affect the internal cables. Therefore, this utility model proposes a pressure-resistant silicon core tube that is easy to connect.

[0006] This application provides a pressure-resistant silicon core tube that is easy to connect, using the following technical solution:

[0007] A pressure-resistant silicon core tube that is easy to connect includes a silicon core tube body, which is composed of an inner layer, a central layer and an outer layer.

[0008] One end of the silicon core tube body is provided with a docking device, which includes a retaining ring and a retaining block.

The bolts need to be screwed in manually, which increases the work steps, reduces docking efficiency, and the bolts are prone to rust after long-term use, making disassembly difficult. In addition, the connection between multiple first and second insertion blocks can easily create gaps, allowing external air to enter and affect the internal cables. Attached Figure Description

[0024] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0025] Reference Figures 1-6 A pressure-resistant silicon core tube that is easy to connect includes a silicon core tube body 1, which is composed of an inner layer 11, a central layer 12 and an outer layer 13.

[0026] Specifically, to enhance the strength of the silicon core tube, the central layer 12 is wound around the outer surface of the inner layer 11. The inner layer 11 is made of high-density polyethylene, which has a smooth inner wall to reduce the friction of the optical cable. The central layer 12 is made of glass fiber reinforced tape, which is spirally wound to improve the axial compressive strength. The outer layer 13 is wrapped around the outer surface of the central layer 12. The outer layer 13 is made of silicone, and its outer surface is corrugated. The corrugated structure disperses the external pressure. Co-extrusion molding technology is used to simultaneously complete the high-density polyethylene inner layer 11, the glass fiber tape winding, and the silicone outer layer 13 coating. The corrugated structure is embossed and shaped by a mold, with a peak spacing of 10 mm and a trough depth of 2 mm.

[0027] In order to quickly complete the docking between the two silicon core tube bodies 1, a docking device is provided at one end of the silicon core tube body 1. The docking device includes a retaining ring 35 and a retaining block 32. After the retaining block 32 of one silicon core tube body 1 is inserted into the retaining ring 35 of the other silicon core tube body 1, the two silicon core tube bodies 1 are fixed.

[0028] Specifically, in order to limit the connection of the two silicon core tubes, the connection device also includes a connection sleeve 2. The connection sleeve 2 is fixedly installed at one end of the inner layer 11. A limit block 21 is fixedly installed on the outer surface of the inner layer 11. A positioning groove 22 is fixedly installed on the inner wall of the connection sleeve 2. The outer surface of the limit block 21 is slidably inserted into the inner wall of the positioning groove 22.

[0029] Specifically, in order to move the locking block 32, a pushing conical sleeve 3 is slidably inserted into the outer surface of the docking sleeve 2. In order to seal one end of the pushing conical sleeve 3, a sealing ring 31 is fixedly installed at one end of the pushing conical sleeve 3. The inner wall of the sealing ring 31 is slidably connected to the outer surface of the docking sleeve 2.

[0030] Specifically, in order to move the locking block 32 toward the locking ring 35, the inner wall of the docking sleeve 2 is slidably inserted into one end of the locking block 32. One end of the locking block 32 passes through the outer surface of the docking sleeve 2 and is rotatably connected to a roller 33, which pushes the inner wall of the conical sleeve 3 to open a sliding groove 34. The sliding groove 34 is inclined, and the outer surface of the roller 33 is slidably connected to the inner wall of the sliding groove 34.

[0031] Specifically, in order to connect and fix the two silicon core tube bodies 1, the retaining ring 35 is fixedly installed on the outer surface of the inner layer 11, and the outer surface of the retaining block 32 is slidably inserted into the inner wall of the retaining ring 35.

[0032] Specifically, in order to drive the conical sleeve 3 to move, a threaded sleeve 4 is connected to the outer surface of the conical sleeve 3 to rotate. The inner wall of the threaded sleeve 4 is threadedly connected to the outer surface of the mating sleeve 2. A threaded connecting block 41 is fixedly installed on the outer surface of the silicon core tube body 1. The inner wall of the threaded sleeve 4 is threadedly connected to the outer surface of the threaded connecting block 41.

[0033] By setting up a docking device, the docking work between silicon core tube bodies 1 can be completed quickly. Through the insertion between the ends of the two silicon core tube bodies 1, and the insertion between the limiting block 21 and the positioning groove 22, the positioning between the two silicon core tube bodies 1 is quickly completed. By rotating the threaded sleeve 4, the movement of the threaded sleeve 4 can drive the conical sleeve 3 to move. After the roller 33 is squeezed, the roller 33 squeezes the locking block 32, so that the locking block 32 is inserted into the retaining ring 35, thus completing the fixation of the other silicon core tube body 1. This allows for the rapid docking of the silicon core tube bodies 1, while reducing the generation of gaps. This solves the technical problem that existing silicon core tubes require multiple bolts to complete the docking between two silicon core tubes. The bolts need to be manually screwed in, increasing the work steps and reducing docking efficiency. Moreover, the bolts are prone to rust after long-term use, making disassembly difficult. Furthermore, the connection between multiple first and second insertion blocks can easily create gaps, allowing external air to enter and affect the internal cables.

[0034] Working principle: By inserting the first end of a silicon core tube body 1 into the inner wall of the docking sleeve 2 at the tail end of the silicon core tube body 1, the limiting block 21 is inserted into the positioning groove 22. After positioning the two silicon core tube bodies 1, the threaded sleeve 4 is rotated. After the threaded sleeve 4 rotates, it moves on the docking sleeve 2, which drives the conical sleeve 3 to move. After the roller 33 rotates in the sliding groove 34, the roller 33 squeezes the locking block 32 and inserts it into the retaining ring 35, thereby fixing the silicon core tube body 1. At the same time, the inner wall of the threaded sleeve 4 is threadedly connected to the outer surface of the threaded connecting block 41, so that the two silicon core tube bodies 1 are fixed and stable.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
