[0002] Widely used in hydraulic systems, machine tools, wind turbines, and other rotating machinery and equipment, this type of rotary joint allows mechanical components to rotate while maintaining a fluid seal, ensuring normal operation and improving equipment reliability and lifespan. However, existing rotary joints with automatically adjustable clearances are often difficult to disassemble when damaged, cumbersome to operate, and prone to seal damage during use, resulting in poor sealing performance and limitations. To address these issues, a rotary joint with automatically adjustable clearance is proposed.

[0003] The announcement number CN205298908U discloses a rotary joint, including a large rotary body, a small rotary body, a large rotating shaft rotatably disposed within the large rotary body and cooperating therewith, and a small rotating shaft rotatably disposed within the small rotary body and cooperating therewith. The small rotating shaft is connected to the large rotating shaft, and a limit baffle is provided between the large rotating shaft and the large rotary body. The large rotating shaft has several first axial oil passages, and the small rotating shaft has several second axial oil passages connected to the first axial oil passages. An end cover plate is fixedly provided at the end of the small rotating shaft. The large rotating shaft and the small rotating shaft are connected by several couplings. By connecting the large rotating shaft and the small rotating shaft with several couplings, the coaxiality between the large rotating shaft and the small rotating shaft is ensured, and the joint rotates smoothly without wobbling after assembly.

[0004] Regarding the aforementioned prior art, the inventor believes that it has the following shortcomings: the rotary joint is connected by several couplings to ensure the coaxiality between the large and small rotating shafts. After assembly, it rotates smoothly without wobbling. However, most rotary joints are difficult to disassemble when damaged, making the operation relatively complicated. Furthermore, the sealing structure is easily damaged during use, resulting in poor sealing performance and limitations. Utility Model Content

[0025] This utility model has the following beneficial effects:

[0026] I. This utility model features a disassembly and assembly structure. When parts need to be disassembled or assembled, the operator can insert the connecting post one into the inner side of the connector body. When the fixing post one and the snap-on post one come into contact, the inclined surface of the fixing post one will push the snap-on post one. When the snap-on post one is pushed by the pressure of the fixing post one, it will drive the fixing post two and the connecting post two to move outward simultaneously. At the same time, the spring is compressed so that the fixing post one can pass through the slot. When the snap-on post one and the fixing post one lose contact, the spring loses its force and can drive the snap-on post one to return to its original position, at which point the fixing post one can be snapped in place. When disassembly is required, the operator can press the connecting post one inside the slot. The movable release post pushes the locking post one to move outward. When the locking post one moves to the inclined surface of the movable release post, the operator can pull out the connecting post one. At this time, the locking post one will also disengage from the movable release post one and the fixed post one. Through the design of the disassembly and assembly structure, when the rotary joint is damaged and needs to be replaced, the operator can easily disassemble and assemble it, making the operation simple and improving work efficiency. The disassembly and assembly structure can achieve simple disassembly and assembly, saving operation time when parts are damaged and need to be replaced, and is convenient.

[0027] II. Based on the aforementioned beneficial effects, a sealing structure is also provided. The operator can close the connector body and sealing column one tightly, and then rotate sealing column one to make snap-fit ​​column two and snap-fit ​​block two snap-fit ​​and fix them. When snap-fit ​​column two and snap-fit ​​block two are fixedly snapped together, snap-fit ​​block one and snap-fit ​​column three can also be snapped and fixed. When it is necessary to remove the connector body, the operator can rotate sealing column one in the opposite direction to make snap-fit ​​column two and snap-fit ​​block two disengage. At the same time, snap-fit ​​block one and snap-fit ​​column three also disengage. By setting sealing ring one and sealing ring two, the sealing effect is improved, and during the snap-fit ​​process, the snap-fit ​​of sealing column one and sealing column two is more stable. The sealing structure can improve the sealing performance of the rotary connector, and it is also convenient to replace the sealing ring. The operation is simple. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] Please see Figure 1-5 As shown, this utility model is a rotary joint with automatically adjustable gap, including a connecting plate 1:

[0039] A disassembly structure 2 is fixedly connected to one side of the connecting plate 1. The disassembly structure 2 includes a connecting post 201, a movable release post 202, and a fixed post 203.

[0040] Connecting post 201 is fixedly connected to the inner side of connecting plate 1, movable unlocking post 202 is movably connected to the outer side of connecting post 201, and fixed post 203 is fixedly connected to the top of connecting post 201.

[0041] The movable release post 202 is connected to the connecting post 201 and the fixed post 203.

[0042] The disassembly and assembly structure 2 also includes a connector body 204 and a slot 205;

[0043] The connector body 204 is movably disposed on the outside of the fixing post 203, and the slot 205 is fixedly disposed in the inner cavity of the connector body 204.

[0044] The disassembly and assembly structure 2 also includes a fixed column 206 and a connecting column 207;

[0045] Fixed column 206 is movably connected to the inside of slot 205, and connecting column 207 is fixedly connected to one side of fixed column 206;

[0046] Fixed column 206 is movably disposed on the outside of slot 205, and connecting column 207 is movably disposed on the inside of slot 205.

[0047] The diameter of the second fixing post 206 is slightly larger than the diameter of the groove 205, so that the second fixing post 206 can be snapped onto the outside of the groove 205 and snapped into the connector body 204.

[0048] The disassembly and assembly structure 2 also includes a spring 208 and a snap-on post 209;

[0049] Spring 208 is movably connected to the outside of connecting post 207, and snap post 209 is fixedly connected to one end of spring 208. One end of spring 208 is fixedly connected to one side of slot 205, and one end of spring 208 is fixedly connected to one side of snap post 209. Snap post 209 is connected to slot 205 through spring 208.

[0050] When the first latching post 209 is under pressure, it will squeeze the spring 208, which will then drive the second fixing post 206 and the second connecting post 207 to move outward simultaneously. When the first latching post 209 and the first fixing post 203 lose contact, the spring 208 will drive the second fixing post 206 and the second connecting post 207 to return to their original positions.

[0051] Working principle: When parts need to be disassembled or assembled, the operator can insert connecting post 201 into the inside of the connector body 204. When fixing post 203 and snap-fit ​​post 209 come into contact, the inclined surface of fixing post 203 will push snap-fit ​​post 209. When snap-fit ​​post 209 is pushed by the pressure of fixing post 203, it will drive fixing post 206 and connecting post 207 to move outward simultaneously. At the same time, spring 208 is compressed so that fixing post 203 can pass through slot 205. When snap-fit ​​post 209 and fixing post 203 lose contact, spring 208 loses its force, which can drive... When the snap-fit ​​post 209 returns to its original position, it can lock the fixed post 203. When disassembly is required, the operator can press the connecting post 201 into the groove 205. The movable release post 202 pushes the snap-fit ​​post 209 outward. When the snap-fit ​​post 209 moves to the inclined surface of the movable release post 202, the operator can pull out the connecting post 201. At this time, the snap-fit ​​post 209 will also disengage from the movable release post 202 and the fixed post 203. Through the setting of the disassembly and assembly structure 2, when the rotary joint is damaged and needs to be replaced, the operator can easily disassemble and assemble it, making the operation simple and improving work efficiency.

[0052] This step, through the setting of disassembly and assembly structure 2, enables simple disassembly and assembly, saving operation time and providing convenience when parts are damaged and need to be replaced.

[0053] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, also includes a sealing structure 3.

[0056] The sealing structure 3 also includes sealing post 2 305, snap-fit ​​post 306, and snap-fit ​​block 2 307;

[0057] Sealing post 2 305 is movably disposed on one side of sealing post 1 301, snap-fit ​​post 306 is fixedly connected to the outside of sealing post 2 305, snap-fit ​​block 2 307 is fixedly connected to the outside of sealing post 2 305, and snap-fit ​​post 306 and snap-fit ​​block 2 307 are both disposed on the outside of sealing post 2 305.

[0061] Working principle: The operator can close the connector body 204 and the sealing column 301 tightly, and then rotate the sealing column 301 to make the snap-fit ​​column 302 and snap-fit ​​block 307 snap and fix it. When the snap-fit ​​column 302 and snap-fit ​​block 307 are fixedly snapped, the snap-fit ​​block 303 and snap-fit ​​column 306 can also be snapped and fixed.

At the same time, the snap-fit ​​block 303 and snap-fit ​​column 306 also disengage. By setting the sealing ring 304 and the sealing ring 308, the sealing effect is improved, and the snap-fit ​​of the sealing column 301 and the sealing column 305 is more stable during the snap-fit ​​process.
