[0005] The technical solution is: a ceramic roller with an adjustable assembly structure, including a long ceramic roller and a short ceramic roller, and also including a convex ring, a protrusion and a limit strip, one end of the long ceramic roller and the short ceramic roller are each provided with a convex ring, the other end of the long ceramic roller and the short ceramic roller are each provided with a ring opening, and the convex ring can be inserted into the ring opening so that the ring opening can fit tightly with the convex ring, limiting strips are arranged at circumferential intervals on the convex ring, and the end of the ring opening is provided with alignment grooves adapted to the limiting strips at circumferential intervals, and the end of the ring opening is also provided with a protrusion that can clamp the limiting strip, and limiting grooves that can be used for the rotation of the limiting strip are arranged at circumferential intervals in the ring opening.

[0006] Furthermore, a notch is reserved between the limiting strip and the inner edge of the convex ring, and the width of the notch is adapted to the width of the protrusion.

[0007] Furthermore, an oblique angle is provided between the connection between the protrusion and the ring opening, and an oblique opening adapted to the oblique angle is provided on one end of the limiting strip close to the recess.

[0008] Furthermore, a locking piece is included, which includes a limiting column. The outer walls of the long ceramic roller rod and the short ceramic roller rod are both provided with a threaded opening near the limiting groove, and a limiting column is screwed into the threaded opening to lock the limiting bar.

[0009] Furthermore, an adjustment hole is provided at the outer end of the limiting column.

[0010] Furthermore, anti-slip grooves are provided at intervals along the circumferential direction on the middle portions of the outer walls of the long ceramic roller and the short ceramic roller.

[0011] The beneficial effects of the present invention are as follows: by docking and combining two ceramic rollers of any length, the smooth transition between the connection points of the ceramic rollers can be improved with the close cooperation between the convex ring and the ring mouth, and the limiting strip can be rotated to engage with the convexity in the ring mouth, thereby achieving the purpose of firmly connecting the docked ceramic rollers.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] Example 1: The utility model provides a ceramic roller with an adjustable assembly structure, see Figure 1-Figure 5 As shown, it includes a long ceramic roller rod 1, a convex ring 10, a short ceramic roller rod 2, a protrusion 30 and a limit strip 5. One end of the long ceramic roller rod 1 and the short ceramic roller rod 2 is provided with a convex ring 10, and the other end of the long ceramic roller rod 1 and the short ceramic roller rod 2 is provided with a ring opening 20, and the convex ring 10 can be inserted into the ring opening 20 so that the ring opening 20 can fit tightly with the convex ring 10, which is conducive to the purpose of smooth connection. Limit strips 5 are arranged at intervals along the circumference of the convex ring 10, and the end of the ring opening 20 is provided with a positioning groove 3 that is compatible with the limit strip 5 along the circumferential direction. The end of the mouth 20 is also provided with a protrusion 30 that can clamp the limit strip 5. The end of the limit strip 5 close to the convex ring 10 is chamfered, which is conducive to the smooth insertion of the limit strip 5 into the corresponding alignment groove 3, thereby facilitating the docking. Limiting grooves 4 are arranged at intervals along the circumferential direction in the ring mouth 20. The ceramic roller rod with the convex ring 10 is used to enable the limit strip 5 on it to rotate in the limiting groove 4. When the limit strip 5 is misaligned with the alignment groove 3, the limit strip 5 and the ceramic roller rod thereon can be clamped and limited. The operation is simple and easy to use.

[0020] For further information, see Figure 1-Figure 4 As shown, a notch 11 is reserved between the limiting strip 5 and the inner edge of the convex ring 10, and the width of the notch 11 is adapted to the width of the protrusion 30, which is beneficial to improve the tightness between the interconnected ceramic rollers, thereby achieving the purpose of stable and smooth connection.

[0021] For further information, see Figure 1-Figure 4 As shown, an oblique angle 40 is provided between the connection between the protrusion 30 and the ring opening 20, and an oblique opening 50 adapted to the oblique angle 40 is provided on the end of the limiting strip 5 close to the recess 11, which is beneficial to improve the stability of the ceramic roller connection.

[0022] When it is necessary to assemble ceramic rollers of different lengths, long ceramic rollers 1 or short ceramic rollers 2 of appropriate lengths can be selected for mutual docking and assembly. Specifically, one end of the convex ring 10 with the limiting strip 5 is inserted into the recess 11, and the end of the ceramic roller with the convex ring 10 is connected to the end of the other ceramic roller with the ring opening 20. When docking, the limiting strip 5 needs to be aligned with the corresponding alignment groove 3. When the limiting strip 5 is fully inserted into the limiting groove 4 of the ring opening 20, hold one of the ceramic rollers tightly. Roller, and rotate the other ceramic roller rod at the same time, so that the limit strip 5 inserted in the ring mouth 20 can rotate in the limit groove 4 until the oblique mouth 50 on the limit strip 5 is completely fitted with the oblique angle 40 in the limit groove 4. In this way, two ceramic roller rods of any length can be conveniently docked and assembled, so that the ceramic roller rods can be combined into the required length, and the joints between the ceramic roller rods that are combined and docked with each other can be tightly fitted and the transition is smooth, which is beneficial to maintaining the integrity and structural strength of the ceramic roller rod assembly.

[0023] Example 2: Based on Example 1, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a locking piece is also included, which includes a limiting column 7. The outer walls of the long ceramic roller rod 1 and the short ceramic roller rod 2 are both provided with a threaded opening 6 near the limiting groove 4, and a limiting column 7 is screwed into the threaded opening 6 to lock the limiting strip 5.

[0024] For further information, see Figure 5 As shown, an adjustment hole 8 is provided at the outer end of the limit column 7, which is convenient for adjusting the position of the limit column 7 so that the limit column 7 can sink into the tube wall of the long ceramic roller rod 1 and the short ceramic roller rod 2 without protruding, which is beneficial to maintaining the flatness between the interconnected ceramic roller rods.

[0025] In addition, see Figure 1 and Figure 2 As shown, anti-skid grooves 9 are provided in the middle of the outer walls of the long ceramic roller 1 and the short ceramic roller 2 at intervals along the circumferential direction, which is beneficial for preventing the long ceramic roller 1 or the short ceramic roller 2 from slipping when being rotated and held, making it more convenient to use.

[0026] When the ceramic rollers are docked and assembled, the hexagonal tool is inserted into the adjustment hole 8 of the limit column 7, and the limit column 7 is rotated to move inward to clamp and position the limit bar 5 assembled in the limit groove 4, so that the limit bar 5 cannot rotate, thereby reinforcing the limit bar 5, which is beneficial to further improve the stability of the combined connection between the ceramic rollers.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
