[0036] Please see Figure 1-8As shown, a rotating shaft mounting assembly includes: a base 1, a rotating shaft body 6, and screws 12. The base 1 has a boss 2 on its top, and a groove 14 is formed on the top of the boss 2. A limiting ring 5 is provided at the bottom end of the rotating shaft body 6. A threaded groove 22 is formed at the bottom end of the limiting ring 5. Opening slots 15 are formed on both sides of the bottom of the limiting ring 5, and the opening slots 15 at the bottom end of the limiting ring 5 are inserted into the grooves 14 for installation. A guide assembly is provided on the top wall of the threaded groove 22. The guide assembly includes a tapered guide block 21, one end of which is fixedly connected to the top wall of the threaded groove 22. The guide block 21 is movably inserted into the interior of the mounting hole 18, and the tapered guide block 21 is movably inserted into the top end of the movable shaft 26. One end of the screw 12 is provided with a limit component. The screw 12 is threaded through the interior of the base 1 and the boss 2, and extends into the threaded groove 22 at the bottom end of the limit ring 5. The limit component includes a locking block 17, a movable shaft 26, a limit shaft 31, a spring 28, a limit protrusion 29, and a flipping block 16. The top end of the screw 12 has a limit groove 23, and the limit shaft 31 is movably inserted into the interior of the limit groove 23. The limit shaft 31 and the movable shaft 26 are movably inserted into the top end of the mounting hole 18. One end of the 6 is fixedly connected, and the other end of the movable shaft 26 has a radial mounting groove 19 and an axial mounting hole 18. The bottom end of the flip block 16 is movably inserted into the interior of the movable shaft 26 and is located inside the mounting groove 19. The locking block 17 is fixedly installed on one side outer wall of the flip block 16. When the movable shaft 26 and the screw 12 are inserted into the interior of the threaded groove 22, the tapered guide block 21 contacts one side wall of the flip block 16, and the locking block 17 is engaged with the threaded groove 22 for limiting the installation of the screw 12 and the movable shaft 26. Before installation, the flip block 16 is rotated inward first. This facilitates the insertion of screw 12 and movable shaft 26 into the threaded groove 22. A protruding rib 27 is provided on the outside of the movable shaft 26, and an arc-shaped groove 30 is formed on the side wall of the threaded groove 22. When the movable shaft 26 is inserted into the inner side of the threaded groove 22, the protruding rib 27 and the arc-shaped groove 30 are engaged in a limiting insertion configuration. One end of both the spring 28 and the limiting protrusion 29 is movably disposed inside the limiting ring 5, and the limiting protrusion 29 is engaged with the spring 28. The other end of the limiting protrusion 29 is engaged with the locking block 17 after the flip block 16 is installed.

[0037] Specifically, this application includes a limiting component. During use, the limiting ring 5 at the bottom of the rotating shaft body 6 is movably inserted into the groove 14 of the boss 2, serving as a preliminary quick positioning and installation mechanism, improving installation efficiency and preventing rotation of the rotating shaft body 6 during installation. Then, the screw 12 is threaded into the base 1 and the boss 2, extending into the threaded groove 22. Simultaneously, the movable shaft 26 is inserted into the inner side of the threaded groove 22. Before inserting the movable shaft 26, the protrusion 27 is aligned with the arc-shaped groove 30, allowing the movable shaft 26 to slide vertically into the threaded groove 22. The threaded installation of the screw 12 and the threaded groove 22 limits and fixes the rotating shaft body 6. Furthermore, when the movable shaft 26 is movably inserted into the threaded groove 22, the tapered guide block 21 is movably inserted into the mounting hole 18, allowing the rotating shaft body 6 and... The installation of base 1 is more stable and less prone to displacement. At the same time, the tapered guide block 21 is inserted into the top of the movable shaft 26, and the arc surface (contact area) of the tapered guide block 21 gradually increases, which can drive the flipping block 16 to slowly rotate outward, so that the locking block 17 engages with the shoulder of the threaded groove 22, thereby improving the fixed connection effect between the rotating shaft body 6 and base 1 and making it less likely to detach. When the rotating shaft body 6 needs to be separated from the base 1, the screw 12 can be turned in the opposite direction, which can drive the movable shaft 26 to gradually move downward. At the same time, under the action of the spring 28, the limiting protrusion 29 can push the flipping block 16 to rotate inward toward the axis of the movable shaft 26. Meanwhile, the horizontal cross section of the tapered guide block 21 gradually decreases, so that the flipping block 16 can slowly rotate, thereby realizing the disassembly of the device.

[0038] In this embodiment, a positioning post 9 is provided at the bottom of the limiting ring 5, and a positioning hole 10 is opened inside the boss 2 and is located below the groove 14. The positioning post 9 is movably inserted into the interior of the positioning hole 10.

[0039] Specifically, the positioning pin 9 serves to position the rotating shaft body 6 during installation and also improves the firmness of the connection.

[0040] A limiting protrusion 13 is fixedly installed on the bottom wall of the groove 14, and a limiting groove 23 is opened at the bottom of the limiting ring 5. The limiting protrusion 13 and the limiting groove 23 are installed in a limiting and movable manner.

[0041] Specifically, in use, the limiting protrusion 13 is inserted into the inside of the limiting groove 23, thereby increasing the contact area at the connection, improving the load capacity of the connection, and preventing deformation.

[0042] The base 1 has a mounting hole 3 at the front and a mounting hole 4 inside. The top of the shaft body 6 is provided with a shaft head assembly 24 and an annular groove 25 is provided on the outside of the top of the shaft body 6.

[0043] Specifically, mounting holes 3 and 4 are used for mounting the base 1 in different directions. The shaft head assembly 24 can meet specific functional requirements or simplify assembly. In scenarios where high precision or frequent disassembly is not required, the rectangular shaft extension can simplify machining and save the machining cost of the keyway. A sealing ring can be installed inside the annular groove 25.

[0044] The bottom of screw 12 has a hexagonal groove.

[0045] Specifically, the six contact surfaces of the hexagonal slot can distribute torque more evenly, and compared to slotted or Phillips head slots, it can withstand greater tightening torque and reduce the risk of tool slippage or slot damage.

[0046] In summary, compared with existing technologies, this rotating shaft mounting assembly has at least the following advantages: It features a limiting component. During use, the limiting ring 5 at the bottom of the rotating shaft body 6 is movably inserted into the groove 14 of the boss 2, providing initial and rapid positioning and installation, improving installation efficiency, and preventing rotation of the rotating shaft body 6 during installation. Then, the screw 12 is threaded into the base 1 and the boss 2, extending into the threaded groove 22. Simultaneously, the movable shaft 26 is inserted into the inner side of the threaded groove 22. Before inserting the movable shaft 26, the protrusion 27 is aligned with the arc-shaped groove 30, allowing the movable shaft 26 to slide vertically into the threaded groove 22. The threaded installation of the screw 12 and the threaded groove 22 provides limiting and fixing for the rotating shaft body 6. Furthermore, when the movable shaft 26 is movably inserted into the threaded groove 22, the tapered guide block 21 is movably inserted into the mounting hole 1. The internal structure of 8 makes the installation of the rotating shaft body 6 and the base 1 more stable and less prone to displacement. At the same time, the tapered guide block 21 is inserted into the top of the movable shaft 26, and the arc surface of the tapered guide block 21 gradually increases, which can drive the flipping block 16 to slowly rotate outward, so that the locking block 17 engages with the shoulder of the threaded groove 22, thereby improving the fixed connection effect of the rotating shaft body 6 and the base 1 and making it less likely to detach. When the rotating shaft body 6 needs to be separated from the base 1, the screw 12 can be turned in the opposite direction, which can drive the movable shaft 26 to gradually move downward. At the same time, under the action of the spring 28, the limiting protrusion 29 can push the flipping block 16 to flip inward toward the axis of the movable shaft 26. Meanwhile, the horizontal cross section of the tapered guide block 21 gradually decreases, so that the flipping block 16 can slowly flip, thereby realizing the disassembly of the device.
