Description

Technical Field

[0001] The utility model relates to the technical field of straight joint structures, in particular to a special-shaped straight joint structure. Background Art

[0002] A straight joint is a joint that connects two pipes into one, while a special-shaped straight joint is a joint that connects two pipes with different straight joints or different cross-sectional shapes. Existing common special-shaped straight joints are all one-piece structures. The disadvantage of this one-piece structure is that if the non-connected ends of the two pipes to be connected have been fixed (such as the special-shaped straight joint is damaged and the joint needs to be replaced), the special-shaped straight joint of the one-piece structure has no margin to match the spacing between the two pipes to be connected, resulting in an unreliable connection. In view of the above problem, the utility model provides a solution. Utility Model Content

[0003] The utility model aims to provide a special-shaped straight section structure.

[0006] Furthermore, the position connecting the coarse interface and the fine interface inner cavity on the inner sealing block is set as a conical guide surface. The setting of the guide surface prevents the diameter from suddenly decreasing and causing movement when the water flows through this position, thereby affecting the service life.

[0007] Furthermore, there are two connecting screws, and the two connecting screws are symmetrically arranged. The two screws are adjusted at the same time to avoid uneven force and tilting caused by adjusting one screw.

[0008] Furthermore, a sealing ring 1 is provided at a position on the inner sealing block that contacts the inner wall of the rough interface, and a sealing ring 2 is provided at a position on the connecting sealing block that contacts the sliding connecting section.

[0009] In summary, the utility model has the following beneficial effects: the utility model arranges the special-shaped straight section into two independent parts assembly structures with a coarse interface and a fine interface, which can be adjusted according to the installation water pipe spacing, thereby improving the adaptability of the special-shaped straight section.

[0014] The utility model is further described in detail below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1-3 As shown, a special-shaped straight section structure includes a coarse interface 1 and a fine interface 2, wherein one end of the coarse interface 1 connected to the fine interface 2 is provided with a connecting sealing block 5, and one end of the fine interface 2 connected to the coarse interface 1 is provided with an inner sealing block 4, wherein the connecting sealing block 5 is slidingly and sealingly connected to the sliding connection section 3 of the fine interface 2 (the inner side of the connecting sealing block 5 is fitted and sealed with the outer wall of the sliding connection section 3, and can slide relatively under the action of an external force), and the inner sealing block 4 is slidingly and sealingly connected to the inner wall of the coarse interface 1 (the outer side of the inner sealing block 4 is fitted and sealed with the inner side of the coarse interface 1, and can slide relatively under the action of an external force), and the sliding connection The diameter of the connecting section 3 is set larger than the diameter of one end of the fine interface 2 connected to the pipe, so that a positioning shoulder is formed at the connection position between the two. The outer side of the connecting sealing block 5 protrudes from the rough interface 1, and a threaded hole is provided on the protruding position of the connecting sealing block 5. A clamping ring 6 is mounted on the outside of the fine interface 2, and the clamping ring 6 is glued to the positioning shoulder position by glue.
