The invention discloses a meshing connector used for connecting composite materials. The meshing connector is used for connecting composite material pipe fittings and comprises a limiting pipe and a connection pipe. The connection pipe is arranged at one end of the limiting pipe. The outer diameter of the limiting pipe is larger than that of the connection pipe. The inner diameter of the limiting pipe is the same as that of the connection pipe. The limiting pipe and the connection pipe are communicated. Two first clamping pieces are symmetrically arranged on the outer wall of the connection pipe. The length of the first clamping pieces is the same as that of the connection pipe. A plurality of grooves are formed in the outer wall of the first clamping pieces at equal intervals. Protruding teeth are formed between the grooves. The cross section of each first clamping piece is in an inferior arc shape. The meshing connector has the advantages of being high in integrity, strong in bearing force, free of stress concentration phenomena, simple in structure and easy to fix.
Description
Technical field [0001] The invention belongs to the field of structural engineering composite material component connection, and specifically relates to an occlusal joint for connecting composite materials. Background technique [0002] Compared with fiber-reinforced composite materials, traditional materials have the characteristics of rigidity, light weight, and corrosion resistance. They have been widely used in the aerospace field and have also received more and more attention in civil applications, such as bridge reinforcement and emergency repairs. For traditional steel emergency rescue bridges and other aspects, the material processing and production technology are also becoming mature. [0003] In the application of a large number of composite materials, the connection problem is a major factor restricting further development. The traditional connection methods of composite materials mainly include glue connection, mechanical connection and glue-mechanical connection. Amo...
