In the aforementioned structure of the ceramic commemorative coin with the self-locking relative rotation body, preferably, the self-locking body is formed by a square tenon protruding outwards from the circumferential edge of the core body and a square mortise recessed inwards from the inner ring of the movable ring.

In the aforementioned ceramic commemorative coin structure with the self-locking relative rotation body, preferably, the self-locking body is formed by an arc tenon protruding outwards from the circumferential edge of the core body and an arc mortise recessed inwards from the inner ring of the movable ring.

In the aforementioned ceramic commemorative coin structure with the self-locking relative rotation body, preferably, the self-locking body is formed by a trapezoidal tenon protruding outwards from the circumferential edge of the core body and a trapezoidal mortise recessed inwards from the inner ring of the movable ring.

In the above-mentioned structure of the ceramic commemorative coin having the self-locking counter rotating body, preferably, the thicknesses of the core body and the movable ring are equal.

In the ceramic commemorative coin structure with the self-locking relative rotating body, preferably, the core body (1) and the self-locking body at the matching part of the movable ring form clearance fit or transition fit.

In the aforementioned structure of the ceramic commemorative coin with the self-locking counter-rotating body, preferably, the core and/or the movable ring surface is provided with a male or female text.

The traditional commemorative coin has different defects, such as time and labor consumption in manual making, poor reproducibility, suitability for making single products and unsuitability for mass production; the casting process generally has the disadvantage of unstable quality due to the natural flow of the fluid; the compression molding has the defects of long production period, long mold opening time, high mold cost, multiple process steps and the like. Aiming at the defects, the technical scheme utilizes the ceramic 3D printing and forming process to form the disc-shaped commemorative coin in one step, and the structural composition of the disc-shaped commemorative coin has the effect that the traditional process is difficult to copy. It comprises core and activity ring, and the activity ring is located the outer lane of core, and both cooperation positions restrict each other through the self-lock body, and the outer lane can use the core to rotate as the center, and the axial degree of freedom of commemorative coin thickness direction promptly is eliminated for commemorative coin has the developments and experiences the sense.

This kind of self-locking body in this scheme can be complicated inner structure, comprises tenon and mortise on the whole, and tenon and mortise are a micro-gap or transition fit's relation, both guaranteed that both can rotate each other, can embody the appearance again and combine together beautifully degree completely.

The surface pattern of the commemorative coin is formed by one-time printing no matter whether the male or the female is a male or a female, various required characters, figures and the like can be obtained without opening a die, and the detail effects of lines, embossments and the like which are the same as those of the existing metal commemorative coin products and even superior to the metal products can be obtained by adopting a nano-grade ink material.

Under the design principle of the scheme, the self-locking body structure, the movable ring shape and the surface scheme can enrich and colorful products in a short time, so that the information exchange of business affairs, annual celebration, tourist souvenir and daily social activities and personalized customization requirements are met.

Compared with the prior art, the beneficial effects of utility model are that: obtain diversified commemorative coin product structure through the self-lock body, provided a rotatory commemorative coin notion of sliding by core and activity ring constitution, satisfied people's collection experience and felt, presented graceful appearance design simultaneously, promoted the information propagation of commemorative coin in social activity.
