Abstract

The application relates to the technical field of barrier-free facilities, and discloses a handrail, a joint, an injection mold of the joint, a core-pulling mechanism and a rack. The joint has a metal framework inside, so that the strength is guaranteed while the appearance and touch are not affected by the exposed metal, and the handrail with the joint also has the advantages. The joint does not need an additional mounting joint, and the assembly can be simplified. The injection mold of the joint can realize efficient and low-cost joint manufacturing. The core-pulling mechanism can fix the framework during manufacturing. The core-pulling assembly rack and the core-pulling disassembly rack can facilitate the assembly and disassembly of the core-pulling mechanism, so that the production efficiency of the joint is improved.
