Abstract

The invention discloses a rigid tube connecting piece with the ends provided with convex rings. The rigid tube connecting piece comprises sealing rings and an inner connecting tube. The two ends of the inner connecting tube are sleeved with rigid tubes with the ends provided with the convex rings. One or more sealing rings are arranged between the inner connecting tube and the rigid tube, with the end provided with the convex ring, located at one end of the inner connecting tube. The rigid tube connecting piece further comprises a fixing sleeve and fastening elastic rings. The fixing sleeve is arranged between the two rigid tubes, with the ends provided with the convex rings, located on the inner connecting tube in a sleeving mode. The fastening elastic rings are arranged in fixing grooves formed in the inner sides of the two ends of the fixing sleeve. An inner fixing boss is arranged between the fixing grooves. The fastening elastic rings are arranged on the portions, located in the fixing grooves, of the rigid tubes with the ends provided with the convex rings in a circular sleeving mode. The fastening elastic rings are located between the outer edges of the fixing grooves and the corresponding convex rings located at the ends of the rigid tubes. The outer edge of each fixing groove is in a conical shape with the outside small and the inside large. By adoption of the rigid tube connecting piece with the end provided with the convex rings, the rigid tubes with the ends provided with the convex rings can be fast connected or detached, so that the working efficiency is improved; and meanwhile, the airtightness is good, the service life is long, and fixing is reliable.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of pipe connectors, in particular to the technical field of a rigid pipe connector with a convex ring at its end. [0003] 【Background technique】 [0004] The application of hard pipes is very common. Hard pipe connectors are used in internal combustion engine machinery and industrial production. Due to physical characteristics, hard pipes have low connection efficiency before. Metal hard pipes are a commonly used pipe. Due to the arrangement relationship, the hard pipe used in the pipeline cycle is longer, but when the hard pipe is longer, the assembly is inconvenient or impossible to assemble, and the direct application of the whole longer hard pipe is restricted. The hard pipe needs to be segmented and then connected and assembled through the hard pipe connection structure to improve the applicability of the hard pipe. [0005] The Chinese utility model patent with the announcement number CN201964057U di...
