Detailed Description

A skylight water guide pipe joint is characterized in that an elastic sleeve 10 communicated with an inner cavity of a pipeline is glued or integrally molded at the pipe head of one pipeline, the elastic sleeve 10 forms a female cavity with an outer section 11, a small inner diameter and an inner section 12, and a male head 20 with a front section 21, a small outer diameter, a middle section 22, a large outer diameter and a rear section 23, and communicated with the inner cavity of the pipeline, the male head 20 and the female cavity form a non-return type inserting fit, and the middle section 22 smooth in the circumferential direction and the inner wall of the female cavity form an interference fit.

The front and the back in the scheme mean that one end close to the joint of the self is the front end far away from the joint and is the back end. The two pipelines are connected through the elastic sleeve 10, no corresponding protruding type connecting piece can be generated, the elastic sleeve 10 is usually made of rubber, the male head is usually made of hard materials, the male head 20 serves as a non-return piece, meanwhile, the smooth peripheral wall of the male head 20 is in interference fit with the inner wall of the female cavity, circumferential sealing is formed, namely, the middle section 22 of the male head 20 is a non-return section and a sealing section, and the production cost of the connector is greatly reduced.

The outer section 11 and the inner section 12 of the elastic sleeve 10 have the same outer diameter, the outer section 11 of the elastic sleeve 10 is a circular tube structure with the same inner diameter, and the inner section 12 of the elastic sleeve 10 is a circular tube structure with the same inner diameter. Therefore, the line contact of the inner section 12 and the outer section 11 of the elastic sleeve 10 can form an annular step, and the non-return effect is improved.

The front section 21, the middle section 22 and the rear section 23 of the male head 20 have the same inner diameter, the rear section 23 of the male head 20 has the same outer diameter, and the front section 21 and the middle section 22 of the male head 20 are uniformly increased in outer diameter from front to back. Thus, an annular step is formed between the rear section 23 and the middle section 22 of the male portion 20, so as to improve the non-return effect, and the smoothly-transitioned front section 21 and the middle section 22 are beneficial to inserting the male portion into the elastic sleeve 10.

The outer diameter of the middle section 22 is larger than the inner diameter of the inner section 12 and larger than the outer diameter of the rear section 23 is larger than or equal to the inner diameter of the outer section 11 and larger than the outer diameter of the front section 21. The outer diameter of the middle section 22 is larger than the inner diameter of the inner section 12, so that effective interference fit is formed, sealing is convenient, the outer diameter of the rear section 23 is larger than or equal to the inner diameter of the outer section 11, and the interference fit can be formed in the rear section 23 to further improve the sealing effect. The inner diameter of the outer section 11 is larger than or equal to the outer diameter of the front section 21, so that a male head can be inserted into the elastic sleeve 10 conveniently.

The elastic sleeve 10 at the front end of the male head 20 is provided with an annular inner step 13, the outer diameter of the front end of the male head 20 is larger than the inner diameter of the annular inner step 13 and is larger than the inner diameter of the male head 20, and the end surface of the annular inner step 13 and the front end of the male head 20 form a joint seal. The front end of the male part 20 thus facilitates the formation of an end seal by the annular inner step 13 of rubber.
