[0027] To solve the technical problems in the background art, as Figures 1-3 shown, the present application provides a technical solution: a novel tubular articulated joint, the characteristics of which are as follows:

[0028] It includes a static articulated part 1, a dynamic articulated part 4 and a connecting pipe 9. One end of the static articulated part 1 is provided with a U-shaped joint 2, and circular grooves 3 are provided on the inner two side walls of the U-shaped joint 2. One end of the dynamic articulated part 4 is provided with a protrusion 5, and rotating shafts 6 adapted to the grooves 3 are provided on both sides of the protrusion 5. The rotating shafts 6 are clamped in the grooves 3, so that an articulated connection is formed between the static articulated part 1 and the dynamic articulated part 4. Specifically, both the static articulated part 1 and the dynamic articulated part 4 are made of metal, having relatively high strength and stiffness to ensure the stability and reliability of the joint. The design of the U-shaped joint 2 enables it to be conveniently connected to the protrusion 5 of the dynamic articulated part 4. The setting of the circular grooves 3 helps the smooth insertion and fixation of the rotating shafts 6. An oil storage groove 7 and a through groove 8 are provided on the rotating shafts 6. Lubricating oil is filled in the oil storage groove 7, one end of the through groove 8 is connected to the oil storage groove 7, and the other end is located on the side of the rotating shaft 6, that is, the through groove 8 can lead out the lubricating oil in the oil storage groove 7 to the side of the rotating shaft 6. As Figure 3As shown, the design of the oil storage tank 7 enables the lubricating oil to form an oil film on the rotating shaft 6, thereby reducing the wear between the rotating shaft 6 and the groove 3 and extending the service life of the joint. Both the static hinge part 1 and the moving hinge part 4 are connected with connecting pipes 9, and the pipe material to be installed can be inserted into the connecting pipes 9. The design of the connecting pipes 9 enables the utility model to be conveniently connected with the pipe material to be installed, improving the practicability of the joint. The connecting pipes 9 are preferably made of metal stainless steel, which is a hollow pipe body, ensuring high strength and stiffness during use to ensure the stability and reliability of the connection.

[0029] It should be noted that as shown in the figure, the reinforcing piece 10 is a thickened circular metal piece. One end of the reinforcing piece 10 becomes one end of the moving hinge part 4, and the reinforcing piece 10 and the protrusion 5 form a T-shaped connection. The setting of the reinforcing piece 10 can effectively improve the bearing capacity and bending resistance of the moving hinge part 4. The connection between the reinforcing piece 10 and the protrusion 5 is made by welding or integrally formed connection. The reinforcing piece 10 can increase the contact area between the moving hinge part 4 and the connecting pipe (9), thereby reducing the burden on the moving hinge part 4 and improving the stability of the overall structure.

[0030] Furthermore, the diameter of the reinforcing piece 10 is designed to be larger than the diameter of the connecting pipe 9. Specifically, the diameter of the reinforcing piece 10 is about 10% larger than the diameter of the connecting pipe 9. This design enables the connecting pipe 9 to be tightly connected to the reinforcing piece 10. The connection method between the connecting pipe 9 and the reinforcing piece 10 is generally welding, and the larger diameter design of the reinforcing piece 10 also provides welding space, thereby improving the stability of the connecting pipe 9. This feature ensures that the reinforcing piece 10 can effectively support the connecting pipe 9.

[0031] It should be noted that the protrusion 5 has a circular arc-shaped side surface, and its arc shape design enables the protrusion 5 not to interfere with other components when rotating around the hinge axis. Specifically, the circular arc-shaped side surface means that the side surface of the protrusion 5 is in an arc shape. There is a certain gap between the circular arc-shaped side surface of the protrusion 5 and the axis of the hinge axis, ensuring the freedom of rotational movement.

[0032] Furthermore, the side surface of the protrusion 5 is designed to be in an arc shape, and the arc is concentric with the rotating shaft 6. Such a design enables the side surface arc of the protrusion 5 to move smoothly along the same central axis as the rotating shaft 6 when the protrusion 5 rotates around the rotating shaft 6, thereby ensuring the smoothness and unobstructedness during the rotation process. The side surface arc of the protrusion 5 can be a smooth continuous curve or a segmented arc, as long as each arc segment is concentric with the rotating shaft 6.

[0033] It should be noted that an anti-collision gasket 11 is provided on the inner wall of the bottom of the U-joint 2. The design of the anti-collision gasket 11 is intended to provide additional protection to prevent direct collision between the moving hinge part 4 and the static hinge part 1 during relative movement, thereby reducing wear and damage. When the moving hinge part 4 and the static hinge part 1 form a 90-degree angle, the anti-collision gasket 11 can abut against the moving hinge part 4, thus playing a buffering role. This design ensures that when the moving hinge part 4 rotates to the vertical position, the anti-collision gasket 11 can remain in contact with the moving hinge part 4, effectively absorbing the impact force. The anti-collision gasket 11 can be made of elastic materials such as rubber, plastic, or other materials with good buffering performance. This material selection enables the anti-collision gasket 11 to deform when subjected to impact and then return to its original shape, thereby providing continuous protection. When assembling the U-joint 2, the anti-collision gasket 11 can be fixed at the bend of the inner wall of the bottom of the U-joint 2. The fixing method can be bonding, embedding, or other appropriate mechanical fixing methods to ensure that the anti-collision gasket 11 will not loosen or shift during long-term use.

[0034] It should be noted that the inner wall of the connecting pipe 9 is further improved to include an anti-slip layer 12. The main function of the anti-slip layer 12 is to provide additional friction when the pipe is inserted into the connecting pipe 9 to prevent the pipe material to be installed from accidentally falling off during movement. The anti-slip layer 12 can be made of a variety of materials, including but not limited to rubber, plastic, metal mesh, or other materials with good anti-slip performance. The design of this layer can include various textures or patterns, such as an uneven surface, ribs, or other forms of mechanical interlocking structures, to increase the contact area and friction coefficient with the pipe material to be installed. The anti-slip layer 12 is provided on the inner wall of the connecting pipe 9 and can be integrally formed or fixed on the inner wall of the connecting pipe 9 by bonding, hot pressing, or other appropriate methods. The thickness and size of the anti-slip layer 12 can be adjusted according to the diameter of the pipe and the expected load conditions. When the pipe material to be installed is inserted into the connecting pipe 9, the anti-slip layer 12 contacts the outer surface of the pipe material, providing sufficient friction to prevent the pipe material from sliding or falling off during use. This design ensures the stability and safety of the connection.

[0035] It should be pointed out that ear seats 13 are provided on both sides of the U-joint 2. The presence of the ear seats 13 is to provide additional support and strength. The ear seats 13 are cylindrical, and the cylindrical design also helps to evenly distribute the force applied through the rotating shaft 6, reducing local stress concentration. The ear seats 13 can be part of the U-joint 2 and are integrally formed with the U-joint 2 through casting, forging, or other manufacturing processes. Additionally, the ear seats 13 can also be installed on both sides of the U-joint 2 by welding, threaded connection, or other mechanical methods.

[0036] It should be noted that the coaxial arrangement of the ear seats 13 means that their centerlines coincide with the centerline of the groove 3. Such an alignment helps to ensure that when the rotating shaft 6 applies a force during operation, the force is transmitted along the centerlines of the ear seats 13 and the groove 3, thereby reducing the additional stress or deformation caused by the eccentric distribution of the force. To achieve this coaxial arrangement, the ear seats 13 can be designed to have a geometric shape and size that match the groove 3. For example, if the groove 3 is circular, then the cross-section of the ear seat 13 is also circular to facilitate their precise alignment. This design also helps to improve the overall rigidity and durability of the U-joint 2, especially when it is subjected to high loads or in dynamic applications.

[0037] Although the embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
