Moreover, they require repeated adjustment with tools such as wrenches, and the installation and disassembly process is cumbersome and time-consuming. Therefore, a high-strength rotary joint stabilization structure is provided to solve the above problems. Utility Model Content

[0012] As a further improvement of this utility model: the arc of the arc-shaped fixing block is adapted to the outer shell of the rotary joint, and the size and position of the two sets of positioning blocks are adapted to the anti-rotation positioning holes at the corresponding positions.

[0029] Reference Figures 1 to 5 In this embodiment of the invention, a high-strength rotary joint stabilizing structure includes:

[0030] Rotary joint body 1;

[0031] The main body fixing mechanism 2 is provided between the fixing surface and the rotary joint body 1, and is used to fix the position of the outer shell part of the rotary joint body 1.

[0032] The rotating head positioning mechanism 3 is located below the main body fixing mechanism 2 and is used to assist in fixing the rotating head part of the rotary joint body 1.

[0033] The rotary joint body 1 includes a rotary joint outer shell 11. Two sets of annular positioning grooves 12 are provided on the outer side of the rotary joint outer shell 11. Two sets of anti-rotation positioning holes 13 are provided on the outer side of the rotary joint outer shell 11 near the main body fixing mechanism 2. A hexagonal sleeve 14 is fixedly connected to the outer side of the rotating head below the rotary joint body 1.

[0034] The main body fixing mechanism 2 includes a first fixing plate 21. An arc-shaped fixing block 22 is fixedly connected to the inner side of the first fixing plate 21. Two sets of positioning blocks 23 are fixedly connected to the inner side of the arc-shaped fixing block 22. The arc of the arc-shaped fixing block 22 is adapted to the outer shell 11 of the rotary joint. The size and position of the two sets of positioning blocks 23 are adapted to the anti-rotation positioning holes 13 at corresponding positions. An arc-shaped locking arm 24 is rotatably connected to the outer side of the arc-shaped fixing block 22. The arc and height of the two sets of arc-shaped locking arms 24 are adapted to the annular positioning groove 12. A locking groove 25 is opened on the side of the arc-shaped fixing block 22. The side of the arc-shaped fixing block 22 has two sets of through holes 26 for insert plates. The side of the arc-shaped fixing block 22 is slidably connected to a locking insert plate 27. Two sets of support springs 28 are fixedly connected between the locking insert plate 27 and the side of the arc-shaped fixing block 22. A locking post 29 is fixedly connected between the two sets of arc-shaped locking arms 24. The locking post 29 is adapted to the locking groove 25. When the support spring 28 is naturally extended without being subjected to external force, the front end of the locking insert plate 27 passes through the through hole 26 and blocks the entrance of the corresponding position of the locking groove 25. The front end of the locking insert plate 27 is arc-shaped on the side near the locking post 29.

[0035] After initial circumferential positioning is achieved by inserting the positioning block 23 into the anti-rotation positioning hole 13, the arc-shaped locking arm 24 rotates around the rotary joint housing 11 into the annular positioning groove 12 to complete axial limiting. Subsequently, the positioning block 23, along with the arc-shaped locking arm 24, rotates completely into the annular positioning groove 12 and is embedded inside the anti-rotation positioning hole 13. Because the front end of the locking plate 27 is arc-shaped, the locking post 29 can directly squeeze the locking plate 27 to make it slightly retract and directly enter the locking groove 25. The support spring 28 pushes the locking plate 27 to automatically insert into the entrance of the locking groove 25 to form a mechanical lock, thus forming a linkage locking mechanism for axial positioning and circumferential anti-rotation.

[0036] The rotating positioning mechanism 3 includes a second fixing plate 31. Multiple sets of through holes are opened on the outer sides of both the first fixing plate 21 and the second fixing plate 31 for connecting with the fixing surface with bolts, etc. The second fixing plate 31 is fixedly connected to the bottom of the first fixing plate 21. A fixing bearing 32 is fixedly connected to the side of the second fixing plate 31. An inner hexagonal fixing block 33 is fixedly connected to the inner side of the inner ring of the fixing bearing 32. The inner hexagonal fixing block 33 is adapted to the hexagonal sleeve 14.

[0037] When fixing the outer shell of the rotary joint body 1, the hexagonal sleeve 14 can be directly inserted into the inner hexagonal fixing block 33 to complete the auxiliary fixing of the rotating part of the rotary joint body 1. The hexagonal sleeve 14 and the inner hexagonal fixing block 33 form a rotation restriction interface. The inner ring of the fixed bearing 32 rotates synchronously with the inner hexagonal fixing block 33, and the outer ring maintains a static connection with the second fixing plate 31.

[0038] The working principle of this utility model is as follows: First, the positioning block 23 of the main body fixing mechanism 2 is aligned with the anti-rotation positioning hole 13 of the rotary joint housing 11 and inserted to achieve the initial circumferential positioning of the rotary joint body 1. At this time, the arc surface of the arc-shaped fixing block 22 is completely in contact with the rotary joint housing 11. The two sets of arc-shaped locking arms 24 are manually rotated so that their arc surfaces slide along the annular positioning groove 12. When the arc-shaped locking arm 24 is fully embedded in the annular positioning groove 12, the locking pin 29 is simultaneously driven to move towards the locking groove 25.

[0039] When the locking pin 29 contacts the arc-shaped front end of the locking plate 27, the outer arc surface squeezes the arc surface of the locking plate 27 to slide laterally along the through hole 26 of the plate and compress the support spring 28. After the locking pin 29 is fully inserted into the locking groove 25, the support spring 28 pushes the locking plate 27 to reset, and its front end is inserted into the entrance of the locking groove 25 to form a mechanical lock, thus completing the linkage locking in the axial and circumferential directions.

[0040] When the positioning block 23 of the main body fixing mechanism 2 is aligned with the anti-rotation positioning hole 13 of the rotary joint housing 11 and inserted, the hexagonal sleeve 14 below the rotary joint body 1 is vertically inserted into the inner hexagonal cavity of the inner hexagonal fixing block 33. The circumferential rotation of the rotating head is restricted by the hexagonal geometric fit, while the hexagonal sleeve 14 is allowed to rotate freely in the inner ring of the fixed bearing 32, further ensuring the stability of the rotating head part of the rotary joint body 1 when it rotates.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
