[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] For reference Figure 1-7 The utility model is described as follows:

[0025] Embodiment 1: An adjustable three-way connection structure includes a tubular first connection pipe 1, the outer diameters of the left and right ends of the first connection pipe 1 are smaller than the outer diameter of the middle section, and the outer diameter changes, and the outer diameters of the left and right ends are smaller than the outer diameter of the middle section. This design is to form a certain step or difference when connecting with the tubular parts to form a stable connection state. The left and right ends of the first connection pipe 1 are respectively used to connect with the tubular parts, and a fixing seat 4 is provided in the middle position of the first connection pipe 1. The fixing seat 4 is located on the lower side of the first connection pipe 1. The fixing seat 4 is a horizontally arranged plate-like structure, and the fixing seat 4 extends to both sides of the radial direction of the first connection pipe 1. A fixing connection hole 41 is provided on the fixing seat 4, so that the fixing seat 4 can be fixedly connected through the fixing connection hole 41. The setting of the fixing connection hole 41 enables the fixing seat 4 to be fixed by bolts, screws and other connecting parts, thereby enhancing the stability of the entire connection structure in the system. The fixing seat 4 provides a stable support for the first connection pipe 1, ensuring that during the connection and use process, the pipeline will not shake or move due to external force.

[0026] A connecting head 2 perpendicular to the first connecting tube 1 is provided in the middle position. The connecting head 2 is arranged on the upper side of the first connecting tube 1. The connecting head 2 includes two clamping parts 21 arranged at intervals. The clamping parts 21 are vertically arranged. A connecting area is formed between the two clamping parts 21 for accommodating and fixing the clamping block 31 of the second connecting tube 3.

[0027] It also includes a tubular second connecting pipe 3, the lower end of which is rotatably connected to the connector 2. A clamping block 31 is provided at the lower end of the second connecting pipe 3, and the clamping block 31 is rotatably connected in the connection area between the two clamping parts 21. The clamping block 31 at the lower end of the second connecting pipe 3 can be embedded between the two clamping parts 21 to ensure the stability of the rotation connection. A connecting hole 1 32 is provided at the center of the clamping block 31, and a connecting hole 2 33 corresponding to the connecting hole 1 32 is provided on the clamping part 21. A rotating shaft 34 is connected between the connecting hole 1 32 and the connecting hole 2 33. Through the cooperation of the connecting hole 1 32, the connecting hole 2 33 and the rotating shaft 34, the rotation adjustment of the second connecting pipe 3 around the rotating shaft 34 is realized. The second connecting pipe 3 can be rotatably adjusted relative to the first connecting pipe 1, which increases the flexibility of the connection structure in the pipeline layout and can adapt to different installation angles and space requirements. During the installation and maintenance process, the position of the second connecting pipe 3 can be conveniently adjusted according to actual conditions, which improves the convenience of operation.

[0028] The clamping block 31 is provided with a positioning hole 1 35, and a plurality of positioning holes 1 35 are provided. The plurality of positioning holes 1 35 are arranged at intervals in the circumference of the connecting hole 1 32. The clamping portion 21 is provided with a positioning hole 2 36 corresponding to the positioning hole 1 35. The positioning hole 1 35 and the positioning hole 2 36 are connected with positioning pins 37, and the position of the second connecting pipe 3 after rotation adjustment can be positioned and fixed by the positioning pins 37. The positioning function, the plurality of positioning holes 1 35 arranged at intervals in the circumference of the connecting hole 1 32, cooperate with the corresponding positioning holes 2 36, and provide a plurality of fixed position options for the second connecting pipe 3. When the second connecting pipe 3 is rotated and adjusted to the desired angle, the positioning pin 37 is inserted into the corresponding positioning hole 1 35 and the positioning hole 2 36, which can effectively lock the position of the second connecting pipe 3 to prevent it from accidentally rotating during operation. If the angle of the second connecting pipe 3 needs to be adjusted multiple times, it can be accurately fixed at the same position each time by the positioning pin 37, ensuring the repeatability of the operation. The plurality of positioning holes 35 arranged at intervals provide a certain degree of angle precision control, and can meet the working conditions that have relatively precise requirements on the connection angle.

[0029] The outer diameter of the lower end of the second connecting pipe 3 is greater than the outer diameter of the upper end thereof, and the upper end of the second connecting pipe 3 is used to connect with the tubular component. This variable diameter design can better connect with tubular components of different diameters, thereby increasing the stability of the connection.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
