Abstract

The invention relates to the technical field of composite component connection, discloses a composite pipe type connection joint, and solves the problem that a pipe type is prone to disengagement dueto the fact that joint connection is not tight enough. The composite pipe type connection joint comprises a composite pipe column I and a composite pipe column II, wherein a screwed joint I is arranged at one end of the composite pipe column I; a screwed joint II close to the screwed joint I is arranged at one end of the composite pipe column II; a connecting ring I is connected to the exterior ofthe screwed joint II; a connecting ring II is connected to the exterior of the screwed joint I; a connecting mechanism II sleeves the connecting ring I; a connecting mechanism I sleeves the connecting ring II; and the connecting mechanism II is connected to the connecting mechanism I through a sealing mechanism; Through the arrangement of the screwed joint I, the screwed joint II, the connectingring I, the connecting ring II, the connecting mechanism I and the connecting mechanism II, limiting and fixing of the connecting ring II and the connecting ring I can be achieved, and then butt jointoperation of the composite pipe column I and the composite pipe column II is completed.

Description

technical field [0001] The invention belongs to the technical field of composite material component connection, in particular to a composite material tubular connection joint. Background technique [0002] Carbon fiber has excellent characteristics such as high specific strength, high specific modulus, light weight, heat resistance, fatigue resistance, corrosion resistance, and creep resistance. It is not only widely used in satellites, launch vehicles, spacecraft, civil aircraft and other aerospace high-tech cutting-edge It has become an irreplaceable strategic basic material for the cutting-edge defense industry, and it has also begun to be widely used in high-speed rail transit, deep-sea oil fields, new energy, construction and other industries, with broad market prospects. [0003] The traditional pipe connection joints adopt adhesive bonding or mechanical connection. The adhesive bonding method is to bond the joint pipes together. However, the long-term use will cause ...
