Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tube assembly, in particular to a ceramic tube assembly. Background Art

[0002] Ceramic tube is a tubular component made of ceramic material, which usually has the characteristics of high temperature resistance, corrosion resistance, insulation, etc. Ceramic tube has excellent high temperature resistance and can work stably for a long time in high temperature environment. It is suitable for high temperature process or equipment and pipelines in high temperature environment. Due to the high chemical stability of ceramic materials, ceramic tube has good corrosion resistance and can resist the erosion of corrosive media such as acid and alkali. It is often used in chemical industry, electronics and other fields. Ceramic tube usually has good insulation performance and can be used to isolate electrical equipment or conductive parts to prevent current leakage or mutual interference of electrical equipment.

[0003] There are mostly three connection methods for existing ceramic tubes during assembly and connection, namely mechanical connection, welding connection and glue connection, but all three connections have disadvantages. Mechanical connection is not sealed enough and will leave gaps because it is difficult to ensure the size and precision of the ceramic tube during firing. Welding requires special equipment and technology, and the welded ceramic tube is easy to break. Finally, glue connection requires attention to the quality of the glue and the cleanliness of the surface of the ceramic tube to ensure a firm connection and no leakage, but subsequent maintenance is more difficult, and when placing cables in existing ceramic tubes, long-term contact may cause friction between the cable sheath and the ceramic tube, causing wear, which may damage the outer protective layer of the cable, and ultimately lead to exposure of the wire core or other damage. Therefore, in order to address the above problems, the inventor proposes a ceramic tube assembly for solving the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] like Figure 1-8 As shown, the utility model provides a ceramic tube assembly, including a main ceramic tube 1, a circular ring patch 2, a middle fixed circular ring 4 and a second rotating fixed ring 18, a friction fixed ring 9 is slidably connected to the outside of the main ceramic tube 1, a ceramic tube groove 5 is opened on the outside of the main ceramic tube 1, and a connecting device assembly is fixedly installed on the outside of the main ceramic tube 1, and the connecting device assembly includes a first rotating fixed ring 3, a first threaded ring 10 and a rubber sealing gasket 7;

[0032] 4 is rotatably connected with a rotating fixed block 13 on the outside, a No. 2 fixed block 14 is fixedly installed on the outside of the rotating fixed block 13, and a cable fixing assembly is connected to the No. 2 fixed block 14, and the cable fixing assembly includes a ceramic gasket 15, a No. 1 sliding rod 16 and a telescopic spring 17. The annular patch 2 is fixedly installed with a friction fixing ring 9 on the outside, and a No. 1 threaded ring 10 is fixedly installed on the outside of the friction fixing ring 9. The No. 1 threaded ring 10 is provided with a rotating fixed block 13 on the outside, and the No. 1 threaded ring 10 is threadedly connected with the No. 1 rotating fixed ring 3, and a raised rotating ring 11 is fixedly installed on the outside of the No. 1 rotating fixed ring 3;

[0033] A No. 2 threaded ring 12 is fixedly installed on the outside of the No. 1 rotating fixed ring 3, and the No. 2 threaded ring 12 is threadedly connected to the middle fixed circular ring 4. An anti-slip protrusion 6 is fixedly installed on the outside of the middle fixed circular ring 4. A gasket groove 8 is opened on the outside of the No. 1 rotating fixed ring 3, and a rubber sealing gasket 7 is fixedly installed inside the gasket groove 8. The rubber sealing gasket 7 is fixedly installed between the main ceramic tube 1 and the gasket groove 8, and the main ceramic tube 1 and the gasket groove 8 can overlap.

[0034] By adopting the above technical scheme, when the ceramic tube needs to be connected, the annular patch 2 is slidably installed on the outside of the main ceramic tube 1, and the No. 1 rotating fixed ring 3 is further placed on the outside of the annular patch 2 and rotated. Since the annular patch 2 is threadedly connected to the No. 1 rotating fixed ring 3, the No. 1 rotating fixed ring 3 rotates and drives the rotating fixed block 13 to contract, so that the annular patch 2 is fixedly connected to the main ceramic tube 1, and the rubber sealing gasket 7 is further placed in the gasket groove 8. Since the annular patch 2 is fixed to the main ceramic tube 1, the No. 1 rotating fixed ring 3 rotates and drives the No. 1 rotating fixed ring 3 to move toward the annular patch 2, and finally the main ceramic tube 1 and the No. 1 rotating fixed ring 3 fix the rubber sealing gasket 7 in the middle. Since the No. 1 rotating fixed ring 3 is threadedly connected to the middle fixed circular ring 4, the middle fixed circular ring 4 rotates and drives the No. 1 rotating fixed ring 3 to move toward the middle fixed circular ring 4, thereby completing the connection of the cable ceramic conduit.

[0035] Embodiment 2

[0036] like Figure 1-8 As shown, based on the first embodiment, the second rotating fixed ring 18 is threadedly connected with the middle fixed circular ring 4, the telescopic spring 17 is fixedly installed on the outside of the second fixed block 14, and the end of the telescopic spring 17 away from the second fixed block 14 is fixedly connected with the ceramic gasket 15, the first sliding rod 16 slides on the outside of the second fixed block 14, and the end of the first sliding rod 16 away from the second fixed block 14 is fixedly installed with the ceramic gasket 15, and the second rotating fixed ring 18 is threadedly connected with the first threaded ring 10;

[0037] The outer sides of the No. 1 rotating fixed ring 3 and the No. 2 rotating fixed ring 18 are provided with gasket grooves 8, and rubber sealing gaskets 7 are fixedly installed. The shape of the annular patch 2 is a conical ring, and the shape of the ceramic gasket 15 is an arc-shaped tile. The number of the annular patches 2 and the No. 1 rotating fixed ring 3 are both two groups and are symmetrically distributed.

[0038] By adopting the above technical solution, when the ceramic tube needs to be connected and the cable is passed through the ceramic, when the cable passes through the second rotating fixing ring 18, the cable will contact the ceramic gasket 15. Since the ceramic gasket 15 is inclined, the cable is finally concentrated in the center of the pipe;

[0039] And with the support of the telescopic spring 17, the cable is always fixed in the center of the ceramic pipe. Fixing the cable in the center of the ceramic tube can reduce the movement and shaking of the cable during use, thereby reducing the wear of the cable sheath and insulation layer and extending the service life of the cable. By fixing the cable, the impact of external mechanical stress on the cable, such as extrusion and stretching, can be reduced, which helps to protect the integrity of the cable structure and conductor. Fixing the cable in the center of the ceramic tube can make the cable wiring more neat, facilitate subsequent maintenance and overhaul work, and improve the maintainability of the cable system. Placing the cable in the center of the ceramic tube and fixing it can help maintain ventilation and heat dissipation around the cable, avoid heat accumulation, and is conducive to the normal operating temperature of the cable.

[0040] Working principle: Through the threaded connection between the annular patch 2 and the No. 1 rotating fixed ring 3, the No. 1 rotating fixed ring 3 is rotated to drive the annular patch 2 to clamp the main ceramic tube 1. Furthermore, since the No. 1 rotating fixed ring 3 is threadedly connected with the middle fixed circular ring 4, the middle fixed circular ring 4 rotates and drives the No. 1 rotating fixed ring 3 to move toward the middle fixed circular ring 4. At the same time, since the middle fixed circular ring 4 is threadedly connected with the rotating fixed block 13, the middle fixed circular ring 4 rotates and drives the rotating fixed block 13 to move toward the middle fixed circular ring 4, finally the main ceramic tubes 1 at both ends are fixedly connected to complete the fixed and sealed connection of the ceramic tubes.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
