[0028] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0029] According to one embodiment of the present disclosure, Figure 1-2 As shown, the present application provides a pipeline rotary joint structure, including:

[0030] A fixing member 1, wherein a cavity 11 with two open ends is provided inside the fixing member 1;

[0031] The rotating member 2 has a flow passage 21 formed inside, and the first end of the rotating member 2 is accommodated in the cavity 11 so that the flow passage 21 is connected to the cavity 11; the rotating member 2 can rotate 360° around the fixed member;

[0032] The limiting member 3 is detachably connected to the fixing member 1 , and the limiting member 3 is configured to fix the rotating member 2 at a specified position when the rotating member 2 rotates around the fixing member 1 to a specified position.

[0033] The structure of the present application is provided with a fixing part 1, a rotating part 2 and a limiting part 3. The fixing part 1 is used to connect with the front-end pipeline. The rotating part 2 can rotate around the fixing part within a range of 360°. The other end of the rotating part 2 can be connected with another pipeline, so that the other pipeline and the front-end pipeline can be in different spatial orientations. Therefore, the present application can meet the occasions where the rigid pipeline needs to convert the interface orientation multiple times by setting the rotating part 2. The 360° rotation is flexible and convenient, saving time and effort. In addition, the limiting part 3 is provided, and the limiting part 3 can fix the rotating part 2 at the specified position after rotating to the specified position. Therefore, the structure of the present application can realize the occasion where the rigid pipeline rotates 360° freely. The structure of the present application is simple to install and arrange, and can be flexibly arranged in an open-air environment. And the structure is compact, material-saving, and has strong industrial aesthetic performance. The structure of the present application can be used in a variety of occasions. As long as the occasion where the interface orientation needs to be converted can be applied to the structure of the present application, the structure of the present application has a universal design, strong interchangeability, and is easy to manufacture.

[0034] For example, the fixing member 1 can be a cylindrical structure, and the two ends of the cavity 11 formed inside the fixing member 1 are open. The fixing member 1 is used as an intermediate connection medium and is fixedly connected to the front-end pipeline, such as welding the two. Therefore, one end of the cavity 11 can be sealed and connected to the medium outlet of the front-end pipeline, and the other end is used to communicate with the flow channel 21 of the rotating member, so that the medium flows to another pipeline through the conversion member.

[0035] For example, the rotating member 2 is generally L-shaped, which is convenient for connection with the fixed member on the one hand, and can meet the requirements of the pipeline conversion interface orientation when the rotating member rotates 360° on the other hand.

[0036] For example, the second end of the rotating member 2 is provided with a flange 4, and the rotating member 2 is used to be connected to another pipeline through the flange 4. The flange 4 can meet the connection strength between the rotating member 2 and another pipeline. In addition, the flange connection method is simple and convenient.

[0037] In one embodiment, an O-shaped groove 22 is formed at the first end of the rotating member 2 , and at least one O-shaped groove 22 is provided. An O-shaped ring 23 is sleeved on the O-shaped groove 22 to ensure a sealed connection between the rotating member 2 and the cavity 11 .

[0038] The O-ring plays a sealing role. There can be multiple O-grooves and corresponding O-rings to prevent leakage of harmful gases.

[0039] In one embodiment, a plurality of spaced limiting holes 12 are provided in the circumferential direction of the fixing member 1 . When the first end of the rotating member 2 is accommodated in the cavity 11 , the limiting member 3 is passed through the limiting hole 12 and the end thereof can abut against the rotating member 2 .

[0040] The limiting member 3 is detachably connected to the limiting hole 12. When the rotating member 2 rotates around the fixing member 1 to a specified position, the limiting member 3 is inserted into the limiting hole 12 and the end of the limiting member 12 exerts a pressing force on the rotating member 2, thereby fixing the rotating member 2 at the specified position.

[0041] For example, the limiting member 3 is a threaded member, such as a stop bolt, the limiting hole 12 is a threaded hole, and the limiting member 3 and the limiting hole 12 are threadedly connected. The limiting holes 12 can be evenly arranged on the fixed member to balance the pressing force on the rotating member. For example, there are three limiting holes 12 arranged in a triangle, which can not only balance the pressing force on the rotating member 2, but also save the use of the limiting member 3.

[0042] In one embodiment, a pipeline rotary joint structure of the present application further includes a bearing 5, which is sleeved on the first end of the rotating member 2 and accommodated in the cavity 11, so that the rotating member 2 can rotate 360° around the fixed member through the bearing 5.

[0043] The bearing 5 can be a deep groove ball bearing, which is easy to buy and has low cost. The bearing 5 is sleeved on the first end of the rotating member 2 and the inner ring is fixedly connected to the first end of the rotating member 2, so that the rotating member can rotate around the bearing. Then the rotating member 2 and the bearing 5 are accommodated in the cavity 11 of the fixed member, so that the rotating member 2 can rotate around the fixed member 1.

[0044] For example, in order to further limit and fix the bearing 5 in the cavity 11 , a bearing ring 6 is provided outside the bearing 5 . The bearing ring 6 is installed on the first end of the rotating member 2 to fix the bearing 5 .

[0045] For example, Figure 3-5 As shown, in order to better accommodate the rotating member 2, the cavity 11 includes a first chamber 111 and a second chamber 112 that are connected to each other. The first chamber 111 is adapted to the bearing 5 to accommodate the bearing 5, and the second chamber 112 is adapted to the first end of the rotating member 2 to accommodate the first end of the rotating member 2.

[0046] The first chamber 111 is arranged close to the bearing, and the second chamber 112 is arranged far from the bearing. When the first end of the rotating member 2 is accommodated in the second chamber 112, the O-ring arranged on the rotating member 2 is sealed with the inner wall of the second chamber 112, so that the second chamber 112 is sealed and connected with the rotating member 2. This satisfies the occasions where sealing is required and prevents the leakage of harmful gas.

[0047] Since the first end of the rotating member 2 is also sleeved with a bearing 5, when the rotating member 2 is accommodated in the cavity, the bearing 5 is immediately accommodated in the first chamber 111. Since the second chamber 112 is already sealed and connected to the rotating member 2, the sealing of the entire device is also guaranteed when the rotating member 2 rotates by the bearing 5. Therefore, since the present application has good sealing performance and strong applicability, it can also be applied to occasions with harmful gas media.

[0048] Furthermore, the cavity 11 further includes a third chamber 113, which is arranged away from the bearing 5 and outside the second chamber. The third chamber 113 is connected to the second chamber 112. When the fixing member 1 is welded and fixed to the front pipeline, the third chamber 113 is connected to the medium outlet of the front pipeline, and the medium enters the flow channel 21 of the rotating member 2 through the third chamber 113, and then enters another pipeline. Figure 5 As shown, the third chamber 113, the second chamber 112 and the first chamber 111 are arranged sequentially from left to right and their inner diameters increase sequentially.

[0049] Alternatively, the bearing 5 may be replaced by a bushing, which is sleeved on the first end of the rotating member 2 and is disposed in the first chamber 111. A bearing ring 6 is provided on the first end of the rotating member 2 outside the bushing to limit the bushing in the first chamber 111. The rotating member 2 is then rotated to rotate around the bushing and the fixed member 1 within a range of 360°. When it is rotated to a specified angle or a specified position, the rotating member 2 is fixed at a specified angle or a specified position by abutting the end of the limit member 3 against the rotating member 2.
