[0002] As an indispensable infrastructure in modern society, pipeline systems often encounter structures such as ducts and beams during installation, modification, and upgrading. These structures can cause considerable difficulties during installation. Patent application CN202322994018.5 discloses an adjustable connector for pipe fittings, which suffers from the following drawbacks: 1) Although the design allows for some angle adjustment through features like arc grooves and ball joints, this design restricts fluid flow to the through-hole, significantly reducing flow rate. Furthermore, the connection between the arc groove and the ball joint is prone to leakage; 2) This connector is unsuitable for construction environments with ducts or beams; 3) The connector's detachable mechanism relies on threaded connections, which suffer from insufficient sealing, high installation requirements, and complex maintenance. Therefore, there is an urgent need for a pipe fitting connector that can adapt to construction environments with ducts or beams, is easy to install and maintain, and provides good sealing, without altering the fluid flow rate within the pipe fitting.

Detailed Implementation

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] This utility model provides a technical solution: a ring-clamp double-sealed zigzag pipe fitting, including a zigzag pipe 1, with ring-clamp connectors 2 fixed at both ends. This utility model, through the design of the zigzag pipe 1, effectively avoids obstacles such as ducts or beams, greatly facilitating construction. The ring-clamp connectors 2 greatly facilitate installation and maintenance, while also significantly improving the sealing performance at the pipe-to-pipe connection. During installation, simply insert the external pipe matching the ring-clamp connector 2 into the ring-clamp connector 2; installation is very convenient. When disassembly is required, simply pull out the external pipe fitting. The ring-clamp joint 2 includes a first annular portion 3 connected to the end of the geometric tube 1. The first annular portion 3 is connected to a first arc-shaped protrusion 4, which is connected to a second annular portion 5. The second annular portion 5 is connected to a third annular portion 6. A sealing ring 16 is fixed within the first arc-shaped protrusion 4, filling the entire portion. This increases both the thickness and width of the sealing ring 16, thereby improving sealing performance. Furthermore, the arc-shaped protrusion of the sealing ring 16, compared to a straight shape, further enhances sealing and prevents leakage. The inner edge of the sealing ring 16 extends beyond the inner edge of the first arc-shaped protrusion 4, thus compressing the sealing ring 16 during insertion of the outer pipe fitting into the ring-clamp joint 2, achieving a sealing effect. By pre-installing and fixing the sealing ring 16 within the first arc-shaped protrusion 4, it is not necessary to install the sealing ring 16 beforehand during on-site installation, facilitating pipe fitting installation and improving installation efficiency.

[0029] The first annular portion 3 is fixed to the geometric tube 1 via a first connecting portion 7, the inner diameter of which is smaller than the outer diameter. The first annular portion 3 is fixed to the first arc-shaped protrusion 4 via a second connecting portion 8, the inner diameter of which is smaller than the outer diameter, and its outer wall is arc-shaped. The first arc-shaped protrusion 4 is fixed to the second annular portion 5 via a third connecting portion 9, which is axially symmetrical to the second connecting portion 8. The second annular portion 5 is fixed to the third annular portion 6 via a fourth connecting portion 10, the inner diameter of which is smaller than the outer diameter. This invention achieves a good natural connection and transition through the arrangement of the first connecting portion 7, the second connecting portion 8, and the third connecting portion 9. The arrangement of the first annular portion 3, the first arc-shaped protrusion 4, the second annular portion 5, the third annular portion 6, the first connecting portion 7, the second connecting portion 8, and the third connecting portion 9 creates a certain height gradient in the ring-clamp joint 2, further improving the sealing and fixing firmness between the ring-clamp joint 2 and the outer tube fitting.

[0030] The inner diameter of the first annular portion 3 is equal to the inner diameter of the second annular portion 4, and the inner diameter of the second annular portion 4 is smaller than the inner diameter of the third annular portion 6. This arrangement makes the outer end of the ring-clamp connector 2 larger than the inner end, facilitating the insertion of the outer pipe fitting. On the other hand, it creates a layered contact between the ring-clamp connector 2 and the outer pipe fitting, thereby improving the sealing performance and the firmness of the fixation between the ring-clamp connector 2 and the outer pipe fitting.

[0031] The shaped tube 1 includes a first bend 11 fixed to the ring clamp connector 2. The first bend 11 is connected to a vertical tube 12, the vertical tube 12 is connected to a second bend 13, and a horizontal tube 14 is connected between the two second bends 13. The left and right ends of the horizontal tube 14 are detachably connected to the left and right second bends 13 respectively, and the upper and lower ends of the vertical tube 12 are detachably connected to the first bend 11 and the second bend 13 respectively. With this setting, the appropriate length of the vertical tube 12 and the horizontal tube 14 can be selected according to the height and width of the duct or beam and other obstacles in the specific installation environment. It has a wide range of applications and greatly saves resources.

[0032] Both ends of the two second bends 13 connected to the horizontal pipe 14 are fixed with ring clamps 2, the end of the first bend 11 connected to the vertical pipe 12 is fixed with ring clamps 2, and the end of the second bend 13 connected to the vertical pipe 12 is fixed with ring clamps 2. The detachable nature of both the horizontal pipe 14 and the vertical pipe 12 is designed to be engaged with the ring clamps 2. This design facilitates the installation and removal of the horizontal pipe 14 and the vertical pipe 12, and also improves the sealing of the connection.

[0033] The first annular portion 3 is provided with a second arc-shaped protrusion 15, and a sealing ring 16 is fixed inside both the first arc-shaped protrusion 4 and the second arc-shaped protrusion 13. The second arc-shaped protrusion 15, together with the first arc-shaped protrusion 4, provides a double seal, thereby greatly improving the sealing performance.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
