When the angle of the floating pipe joint 3 changes, the bellows 9 will bend according to the change in angle.

[0021] A universal joint structure supporting the floating pipe joint 3 to rotate is sleeved on the outside of the floating pipe joint 3, and the universal joint structure is fixedly connected to the side reinforcing plate 6. A damping positioning component 8 is provided at the connection between the universal joint structure and the floating pipe joint 3. The universal joint structure is sleeved on the outside of the floating pipe joint 3 to support the floating pipe joint 3 to rotate in more directions. After the floating pipe joint 3 completes the angle adjustment, the damping positioning component 8 will lock the floating pipe joint 3, which has high flexibility and stronger applicability.

[0022] Regarding the universal joint structure: the universal joint structure includes an inner ball sleeve 4 and an outer ball sleeve 5. The inner ball sleeve 4 is sleeved on the outside of the floating pipe joint 3. The inner ball sleeve 4 is fixedly connected to the floating pipe joint 3. The two ends of the floating pipe joint 3 extend to the outside of the inner ball sleeve 4. The outer ball sleeve 5 is sleeved on the outside of the inner ball sleeve 4. The outer ball sleeve 5 is slidably connected to the inner ball sleeve 4. The two ends of the inner ball sleeve 4 extend to the outside of the outer ball sleeve 5. The outer ball sleeve 5 is fixedly connected to the side reinforcement plate 6 through a bracket structure. The universal joint structure consists of two parts: the inner ball sleeve 4 and the outer ball sleeve 5. The inner ball sleeve 4 is sleeved on the outside of the floating pipe joint 3 and fixed to the floating pipe joint 3. The outer ball sleeve 5 is sleeved on the outside of the inner ball sleeve 4 to limit the inner ball sleeve 4. The spherical surface of the inner ball sleeve 4 and the outer ball sleeve 5 are mainly used to fit so that the inner ball sleeve 4 can rotate freely in the spherical surface of the outer ball sleeve 5, thereby realizing the universal rotation of the floating pipe joint 3.

[0023] More specifically, the support structure includes side support plates 7 provided on both sides of the outer ball sleeve 5, one end of the side support plate 7 is fixedly connected to the outer ball sleeve 5, and the other end of the side support plate 7 is fixedly connected to the side reinforcement plate 6. Each outer ball sleeve 5 is fixed to the side reinforcement plate 6 through a support structure, and the support structure is the side support plates 7 provided on both sides of the outer ball sleeve 5, and the two side support plates 7 fix the outer ball sleeve 5 and keep the inner ball sleeve 4 in a suspended state.

[0024] In order to facilitate the maintenance of the universal joint structure by the staff, in a preferred embodiment, the support structure includes side support plates 7 arranged on both sides of the outer ball sleeve 5, one end of the side support plate 7 is fixedly connected to the side reinforcement plate 6, and the other end of the side support plate 7 is provided with a bolt seat 10, and the bolt seat 10 is equipped with a fixing bolt 11, which passes through the bolt seat 10 and is threadedly connected with the bolt hole opened on the outside of the outer ball sleeve 5. The outer ball sleeve 5 is fixed to the side support plate 7 by a detachable connection. When the inner ball sleeve 4 and the outer ball sleeve 5 are maintained, the fixing bolt 11 on the bolt seat 10 can be screwed out from the bolt hole on the outside of the outer ball sleeve 5.

[0025] The damping positioning structure limits the rotation of the floating pipe joint 3 by increasing the friction between the inner ball sleeve 4 and the outer ball sleeve 5. Specifically, the damping positioning assembly 8 includes a tension bolt 81 and an arc-shaped pressure plate 83. The tension bolt 81 is threadedly connected to a threaded hole 82 provided on the outer side of the outer ball sleeve 5. The arc-shaped pressure plate 83 is arranged in an arc-shaped groove 84 provided on the inner side of the outer ball sleeve 5. The arc-shaped groove 84 is connected to the threaded hole 82. The arc-shaped pressure plate 83 faces the side of the inner ball sleeve 4 and fits the inner ball sleeve 4. It should be noted that the arc-shaped pressure plate 83 is rotatably connected to the tension bolt 81 away from the side of the inner ball sleeve 4. When the floating pipe joint 3 is rotated, the inner ball sleeve 4 fixed to the floating pipe joint 3 will rotate accordingly. After adjusting the installation angle of the floating pipe joint 3, the tension bolt 81 is screwed into the threaded hole 82. The tension bolt 81 pushes the arc pressure plate 83 toward the inner ball sleeve 4 and squeezes the inner ball sleeve 4. The damping between the inner ball sleeve 4 and the arc pressure plate 83 is increased, limiting the inner ball sleeve 4 from sliding further.

[0026] More specifically, the arc-shaped pressing plate 83 and the inner ball sleeve 4 are both made of rubber, and a plurality of dot-shaped protrusions are provided on the side of the arc-shaped pressing plate 83 facing the inner ball sleeve 4. The dot-shaped protrusions on the arc-shaped pressing plate 83 are used to increase the friction between the arc-shaped pressing plate 83 and the inner ball sleeve 4, so that the inner ball sleeve 4 will not slip after being pressed by the arc-shaped pressing plate 83, causing the angle of the floating pipe joint 3 to change.

[0027] Working principle: the four pipe joints 2 on the outside of the connecting seat 1 are connected to each other, the bellows 9 is arranged between the pipe joint 2 and the floating pipe joint 3, and the floating pipe joint 3 is connected to the pipe joint 2. The universal joint structure is sleeved on the outside of the floating pipe joint 3 to support the floating pipe joint 3 to rotate in more directions. When the angle of the floating pipe joint 3 changes, the bellows 9 will bend according to the change in angle, with high flexibility and stronger applicability. After the floating pipe joint 3 completes the angle adjustment, the damping positioning assembly 8 will lock the floating pipe joint 3.
