[0002] Wear-resistant ceramic pipe, also known as metal-ceramic lined composite pipe, is a high-performance pipe that combines the characteristics of metal and ceramic. It has the properties of wear resistance, corrosion resistance, heat resistance, thermal shock resistance and mechanical shock resistance, and can effectively prevent wear or rust inside the pipe during transportation.

[0003] Due to the characteristics of ceramic metal tubes, they are now used in more and more fields. However, the outer surface of traditional wear-resistant ceramic tubes is directly exposed to the air. When used in winter, if the wear-resistant ceramic tubes are not protected in time, the surface of the wear-resistant ceramic tubes can easily freeze and crack due to the low temperature, affecting the service life of the wear-resistant ceramic tubes. In addition, when installing and transporting the wear-resistant ceramic tubes, no protective measures are set on the outer surface of the wear-resistant ceramic tubes, which can easily cause damage in the event of a collision.

DETAILED DESCRIPTION

[0017] 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.

[0018] Example: Figure 1-5 As shown, the utility model provides a wear-resistant ceramic tube, including a ceramic inner tube 1, a metal outer tube 12 is installed on the outer surface of the ceramic inner tube 1, a fixing ring 2 is fixedly installed on one end of the metal outer tube 12, a plurality of first limiting rods 14 distributed in an array are fixedly installed on one side of the fixing ring 2, a heat preservation cover 13 is slidably provided on the outer surface of the plurality of first limiting rods 14, a plurality of heat preservation cottons 132 distributed in an array are fixedly installed in the middle of the heat preservation cover 13, by arranging the heat preservation cotton 132, through the heat preservation effect of the heat preservation cotton 132, the ceramic tube is prevented from being frozen and cracked due to the low temperature when used in winter, a plurality of second springs 31 distributed in an array are fixedly installed on the outer surface of the heat preservation cover 13, a protective cover 3 is fixedly installed on the other end of the plurality of second springs 31, and two groups of symmetrically distributed fixing rods 133 are fixedly installed on one end of the heat preservation cover 13, and by arranging the second spring 31, when the ceramic inner tube 1 is hit, the force generated by the impact can be buffered under the reaction force of the second spring 31.

[0019] A first slide groove 21 is provided in the middle of both ends of the fixing ring 2, and a first slider 22 is slidably mounted inside the two first slide grooves 21, and two symmetrically distributed second limit rods 222 are provided in the middle of the two first sliders 22, and symmetrically distributed second sliders 23 are fixedly installed on both sides of the two first sliders 22, and the four second sliders 23 are slidably mounted inside the first slide groove 21, and a first spring 231 is fixedly installed in the middle of one side of the four second sliders 23, and the other ends of the four first springs 231 are fixedly installed on both sides of the first slide groove 21. By setting the first slider 22 and the first spring 231, the second limit rod 222 is driven to move under the mutual cooperation of the first spring 231 and the first slider 22, so as to facilitate the installation and disassembly of the heat preservation cover 13.

[0020] A plurality of array-distributed limiting grooves 131 are provided in the middle of the heat preservation cover 13, and a plurality of first limiting rods 14 are slidably clamped in the limiting grooves 131. By setting the limiting grooves 131 and slidingly inserting the first limiting rods 14 in the limiting grooves 131, the heat preservation cover 13 can be limited to prevent the heat preservation cover 13 from rotating.

[0021] One end of the two groups of fixing rods 133 is provided with a limiting hole 134, and the four second limiting rods 222 are slidably clamped inside the limiting hole 134. By setting the limiting hole 134 and sliding the second limiting rods 222 inside the limiting hole 134, the fixing rods 133 can be limited and fixed.

[0022] Two symmetrically distributed second slide grooves 221 are provided on one side of the two first sliding blocks 22, and one end of the four second limiting rods 222 are fixedly installed in the middle of the second slide groove 221. By setting the second slide groove 221, when the fixing rod 133 is inserted into the interior of the fixing ring 2, the fixing rod 133 is slidably clamped in the interior of the second slide groove 221, and under the reaction force of the first spring 231, the second limiting rod 222 is driven to move, so that the second limiting rod 222 is clamped in the interior of the limiting hole 134.

[0023] The outer surface of the ceramic inner tube 1 is provided with a plurality of grooves 11 distributed at equal intervals. By providing the grooves 11, the contact area between the outer surface of the ceramic inner tube 1 and the glue is larger, so that the adhesion effect with the metal outer tube 12 is better.

[0024] Working principle: In actual use, the ceramic inner tube 1 is connected to the metal outer tube 12 by applying glue to the outer surface of the ceramic inner tube 1 and then installing it in the metal outer tube 12. The first limiting rod 14 is slidably inserted into the limiting groove 131 to limit the heat preservation cover 13 to prevent the heat preservation cover 13 from rotating, so that it is installed on the outer surface of the metal outer tube 12. When the heat preservation cover 13 is hit, the second spring 31 and the protective cover 3 are installed on the outer surface of the heat preservation cover 13. The impact force can be buffered by the reaction force of the second spring 31, so that the impact force will not directly act on the outer surface of the metal outer tube 12, thereby preventing the ceramic inner tube 1 and the metal outer tube 12 from being damaged due to the impact.

[0025] By pressing the first slider 22, the heat preservation cover 13 is pushed to move in the direction of the fixing ring 2, so that the fixing rod 133 is inserted into the interior of the fixing ring 2. By loosening the first slider 22, the first slider 22 is driven to move outward under the reaction force of the first spring 231, so that the second limiting rod 222 is clamped in the interior of the limiting hole 134, that is, the limiting of the fixing rod 133 is completed, and the heat preservation cover 13 can be limited and fixed, that is, the protective cover 3 is also fixedly installed on the outside of the metal outer tube 12. When disassembly is required, the first slider 22 is pressed inwardly to make the second limiting rod 222 away from the interior of the limiting hole 134, that is, the heat preservation cover 13 can be pulled so that the fixing rod 133 is away from the interior of the first sliding groove 21, that is, the second limiting rod 222 no longer limits the fixing rod 133, and the first limiting rod 14 is pulled out from the interior of the first limiting groove 131, thereby completing the disassembly of the heat preservation cover 13, thereby making it more convenient to install and disassemble the heat preservation cover 13.

[0026] 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.
