the first rotating base 1 is externally connected with a first fixed end 11. And a spherical first accommodating groove 12 is arranged inside the first rotating base 1. The inner wall of the first containing groove 12 is provided with a first rotating packing ring 13, a first ball fixing ring 14 and a first anti-release device 15, wherein the first anti-release device 15 is a C-shaped clip.

Two ends of the first rotating tube 2 are respectively provided with a spherical first pivot seat 21 and a first combining end 22. The first pivot seat 21 is combined in the first accommodating groove 12 of the first rotating seat 1, so that the first rotating tube 2 can be pivoted at any angle relative to the first rotating seat 1 (as shown in fig. 4). The outer wall of the first pivot seat 21 is tightly attached to the inner wall of the first accommodating groove 12 by the first rotating packing ring 13 and the first ball fixing ring 14 to form a sealing and leakage-proof function, and then the first anti-releasing ring 15 is fastened to the outer wall of the first pivot seat 21, so that the first pivot seat 21 cannot be released from the first accommodating groove 12. The outer wall of the first pivot seat 21 is further sleeved with a first dust-proof sleeve 23 for shielding the gap between the outer wall of the first pivot seat 21 and the inner wall of the first accommodating groove 12 to prevent dust, moisture or other foreign matters from entering. Two opposite spaced flanges 221 are annularly arranged on the outer wall surface of the first combining end 22, a slot 222 is formed between the two flanges 221 at intervals, a plurality of openings 223 are axially formed on the two flanges 221, and the openings 223 are communicated with the slot 222. And the inner wall surface of the first rotation pipe 2 near the middle section is provided with a first ring groove 24 (as shown in fig. 5), and a first sliding packing ring 241 is embedded in the first ring groove 24.

The second rotary base 3 is externally connected with a second fixed end 31. And a second spherical accommodating groove 32 is formed in the second rotary base 3. The inner wall of the second receiving slot 32 is provided with a second rotary tightening ring 33, a second ball fixing ring 34 and a second anti-release device 35, wherein the second anti-release device 35 is a C-shaped clip.

Two ends of the second rotating tube 4 are respectively provided with a spherical second pivot seat 41 and a second coupling end 42. The second pivot seat 41 is combined in the second accommodating groove 32 of the second rotary seat 3, so that the second rotary tube 4 can be freely pivoted at an angle relative to the second rotary seat 3 (as shown in fig. 6). The outer wall of the second pivot joint seat 41 is tightly attached to the inner wall of the second containing groove 32 by the second rotary packing ring 33 and the second ball fixing ring 34 to form a sealing and leakage-proof function, and then the second anti-releasing ring 35 is fastened to the outer wall of the second pivot joint seat 41, so that the second pivot joint seat 41 cannot be released from the second containing groove 32. A second dust-proof cover 43 is further sleeved on the outer wall surface of the second pivot seat 41 to shield the gap between the outer wall surface of the second pivot seat 41 and the inner wall surface of the second accommodating groove 32, so as to prevent dust, moisture or other foreign matters from entering. An anti-falling cover 44, an anti-falling stopper 45, a plurality of positioning pieces 46 and a positioning ring 47 (as shown in fig. 5) are movably sleeved on the outer wall surface of the second coupling end 42.

Thus, the locking block 441 is blocked by the front and rear blocking edges 221 and the positioning plate 46, and the anti-slip cover 44 is prevented from being freely moved and loosened by the inclined blocking surface 451 of the anti-slip block 45 and the front and rear blocking actions of the positioning ring 47, so that the first rotary tube 2 and the second rotary tube 4 can be firmly combined without using any bolt or flange locking device, thereby saving labor and time.

As shown in fig. 5, when physical phenomena such as earthquake, cold contraction, thermal expansion, etc. occur, the first rotating pipe 2 and the second rotating pipe 4 can relatively expand and contract to avoid deformation or breakage due to external force. Meanwhile, the first rotating pipe 2 and the second rotating pipe 4 can prevent the leakage of the liquid by the sealing function of the first sliding packing ring 241 in the first ring groove 24.

As shown in fig. 4, the first rotating tube 2 can also be pivoted by an angle relative to the first pivot seat 21 in the first accommodating groove 12 of the first rotating seat 1, so as to counteract the influence of the external force, thereby preventing the first rotating tube 2 from being deformed or broken by the external force. Furthermore, the first rotation tube 2 can form a sealing and leakage-proof function by the close contact of the first rotation packing ring 13 and the first sphere fixing ring 14, so as to prevent the liquid being transported from leaking.

As shown in fig. 6, the second rotating tube 4 can also pivot the second pivot seat 41 in the second receiving groove 32 of the second rotating seat 3 by an angle to counteract the external force, so as to prevent the second rotating tube 4 from being deformed or broken by the external force. Furthermore, the second rotating pipe 4 can form a sealing and leakage-proof function by the close fit of the second rotating packing ring 33 and the second ball-shaped fixing ring 34, so as to prevent the liquid being transported from leaking.

In another embodiment of the present invention, as shown in fig. 9, the difference between the present embodiment and the above embodiments is that only a third rotating pipe 5 is extended and connected between the first rotating pipe 2 and the second rotating pipe 4, the inner wall surface of the third rotating pipe 5 near the middle position is provided with a second annular groove 54, a second sliding packing ring 541 is installed in the second annular groove 54, and the second sliding packing ring 541 has a sealing function to prevent the liquid being transported from leaking. The third rotating tube 5 is connected and fixed between the first rotating tube 2 and the second rotating tube 4 by the locking and fixing actions of the anti-falling cover 44, the anti-falling stopper 45, the positioning plate 46 and the positioning ring 47. Thus, it is further possible to continuously extend the length to be conveyed by assembling a plurality of the third rotating pipes 5 as shown in FIG. 10.

Therefore, the flexible pipe device with flexible deviation of the utility model does not need to use any bolt or flange, so the manpower and time for locking the bolt can be saved. Due to the relatively simple structure of the components, the overall weight is relatively light after assembly. When the first rotary pipe 2 and the second rotary pipe 4 are affected by external force such as earthquake, cold contraction, thermal expansion and the like, the first rotary pipe 2 and the second rotary pipe 4 can relatively generate a telescopic effect to counteract damage of the external force. The first rotating tube 2 and the second rotating tube 4 can also pivot at an angle relative to the first pivoting seat 21 and the second pivoting seat 41 respectively, and also have an effect of offsetting external force, so as to achieve the effect of avoiding deformation or breakage.
