The invention belongs to the tire demounting equipment for heavy vehicles, and relates to a large heavy vehicle used rim lock ring having mortise and tenon joints. The rim lock ring for large heavy vehicles in the prior art has the defects that the mounting and the demounting are complicated, many working procedures are needed, and many personal safety accidents are caused during mounting and demounting. The rim lock ring disclosed by the invention is formed by more than two identical lock ring units which have mortise and tenon structures and are connected together. A tongue cavity (3) is formed in one end of each lock ring unit, and a convex tongue (4) is arranged at the other end of each lock ring unit; each tongue cavity (3) mates with the tongue (4) of the adjacent lock ring unit; the optimum number of the lock ring units is 2-4. The rim lock ring disclosed by the invention has the advantages that the single lock rings have the same shape, so that the manufacture is easy; the mating of the mortis and tenon structures are tight, so that the locking function is good; the locking rings are convenient to mount and demount, so that the tires of the heavy vehicles are convenient to mount and demount; when the lock rings are mounted or demounted, the cooperation of many people using crowbars is not needed, the personal safety accidents are avoided, and the lock rings are safe to mount and demount.
