Embodiment Construction

[0029] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0030] The compound material round pipe adhesive connection structure provided by the present invention adopts the composite material pipe 1 on the outside, embedded annular sealing rings 3 and 7, and metal parts 2. This composite material is glued to the metal part structural form, such as Figure 1 to Figure 5 shown.

[0031] Several glue injection ports 6 are processed at both ends of the composite material pipe 1, and the positions of the glue injection ports 6 are outside the bonding area.

[0032] A glue groove 4 , a glue guide groove 5 , and grooves for installing the sealing ring 3 and the sealing ring 7 are processed on the metal part 2 .

[0033] The grooves for installing the seal ring 3 and the seal ring 6 are located on both sides of the glue groove 4 and the glue guide groove 5 .

[0034] The width of the glue guide groove 5 can be great...

Abstract

The invention discloses a glue joint connecting structure of a composite round pipe. The glue joint connecting structure is composed of the composite round pipe (1) and a metal part (2) connected with the composite round pipe (1) in a glue joint manner. A plurality of glue pouring ports (6) are formed in the joint of the composite round pipe (1). A groove for installing a first annular sealing ring (3), a glue groove (4), a glue guiding groove (5) and a groove for installing a second annular sealing ring (7) are sequentially machined in the joint of the metal part (2) from left to right. According to the glue joint connecting structure, the glue joint defect of composites can be greatly reduced, the glue joint connecting performance and reliability of the composites are improved, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to a composite material round pipe glued connection structure, more specifically a composite material round pipe and metal glued connection structure. Background technique [0002] The development of modern high technology is inseparable from composite materials. Composite materials have the advantages of improving structural integrity, but due to the needs or limitations of design, process, cost, and maintenance, certain design and process separation surfaces, maintenance covers, and various external interfaces are required. The load transfer of these parts must be solved by corresponding connection methods, so the connection structure of composite materials is inevitable. Connection design is an essential key link in composite material structures. The connection usually occurs in the transition area between the composite material part and the metal part or the composite material part. Due to the stress concentration, the conne...
