[0021] Example

[0022] like Figure 1 As shown, a detachable air shaft 1 mounting assembly includes an air shaft 1 and shaft heads 2. Both ends of the air shaft 1 are provided with shaft heads 2. A rotating block 7 is provided at one outer end of each shaft head 2, and the rotating block 7 is connected to other mechanical equipment that uses the air shaft 1 in conjunction with it. The rotating block 7 has a mounting groove 8 for mounting the shaft head 2 at one end near the shaft head 2. The mounting groove 8 is U-shaped and corresponds to the shaft head 2. The shaft head 2 and the rotating block 7 are detachably connected. Limiting protrusions 9 are provided on both sides of the end of the shaft head 2 near the rotating block 7. A limiting groove 10 corresponding to the limiting protrusions 9 is provided on the inner wall of the mounting groove 8, and the limiting protrusions 9 are located within the limiting groove 10. When installing or removing the air shaft 1, the air shaft 1 is lifted using a special lifting tool, and the limiting protrusions 9 on the shaft head 2 are installed into the limiting groove 10 through the opening side of the U-shaped mounting groove 8, thus achieving the installation and positioning of the air shaft 1.

[0023] like Figure 3As shown, a sliding sleeve 4 is fitted on the outer side of the rotating block 7. The inner wall of the sliding sleeve 4 slides in contact with the outer wall of the rotating block 7. The sliding sleeve 4 moves along the length of the rotating block 7. A sleeve 19 is provided on the inner side of the top of the sliding sleeve 4 along the length. Symmetrical mounting plates 3 are provided on the top of the rotating block 7 along the length. A screw 5 is provided between the symmetrical mounting plates 3. One end of the screw 5 passes through the mounting plate 3, and the other end is rotatably connected to the mounting plate 3. A motor 6 is provided at the end of the screw 5 that passes through the mounting plate 3. The output end of the motor 6 is connected to the screw 5 through a coupling.

[0024] A sleeve 19 is provided on the inner side of the top of the sliding sleeve 4 along its length, and the sleeve 19 is welded and fixed to the sliding sleeve 4. The inner wall of the sleeve 19 has a threaded groove that mates with the thread on the screw 5, and the sleeve 19 is fitted onto the outer side of the screw 5. When the motor 6 is started, the motor 6 rotates, driving the screw 5 to rotate. The sleeve 19 is threadedly connected to the screw 5. As the screw 5 rotates, the sleeve 19 moves on the screw 5, causing the sliding sleeve 4 to slide outside the rotating block 7. The sliding of the sliding sleeve 4 outside the rotating block 7 can block the side of the mounting groove 8, preventing the shaft head 2 from moving. When the sliding sleeve 4 slides to the outside of the mounting groove 8, the mounting groove 8 is exposed, facilitating the disassembly of the shaft head 2.

[0025] like Figure 2 As shown, the bottom of the sliding sleeve 4 is provided with a fixing component that is fixedly connected to the bottom of the rotating block 7. The fixing component includes a fixing hole 16, a pull rod 11, and a limiting hole 15. The bottom of the sliding sleeve 4 is provided with a fixing hole 16, and the bottom of the rotating block 7 is provided with a limiting hole 15 corresponding to the fixing hole 16. The diameters of the fixing hole 16 and the limiting hole 15 are the same. A limiting block 13 is provided at the bottom of the fixing hole 16, and the top of the fixing hole 16 communicates with the bottom of the limiting hole 15. After the shaft head 2 is installed in the mounting groove 8, the sliding sleeve 4 is moved to the left until the fixing hole 16 of the sliding sleeve 4 communicates with the limiting hole 15.

[0026] A pull rod 11 is provided inside the fixing hole 16. One end of the pull rod 11 passes through the limiting block 13 and extends to the outside of the fixing hole 16, while the other end is provided with a slider 14. The limiting block 13 has a movable hole for the pull rod 11 to pass through. The two ends of the slider 14 slide in contact with the inner walls of the limiting hole 15 and the fixing hole 16, respectively. A spring 12 is sleeved on the outside of the limiting rod. One end of the spring 12 is connected to the top of the limiting block 13, and the other end is connected to the bottom of the slider 14. A locking head 18 is provided at the top of the slider 14. Two elastic cards 17 are provided at the top of the limiting hole 15, which cooperate with the locking head 18. The locking head 18 can be inserted between the two elastic cards 17.

[0027] When using the air shaft 1, first pull the lever 11. The lever 11 drives the chuck 18 to pull out between the elastic clips 17 on both sides. The slider 14 slides along the inner wall of the limiting hole 15, and the spring 12 is compressed until the slider 14 slides into contact with the inner wall of the fixing hole 16. The lever 11 is then pulled out of the limiting hole 15 and can no longer limit the sliding sleeve 4. Then, the motor 6 and the screw 5 work together to move the sliding sleeve 4 to the right, moving it to the outside of the mounting groove 8, exposing the mounting groove 8. The air shaft 1 is then lifted using a special lifting tool. The limiting protrusion 9 of the shaft head 2 is installed into the limiting protrusion groove 10 through the opening side of the U-shaped mounting groove 8. Then, the sliding sleeve 4 is moved to the left by the motor 6 and the screw 5 until the fixing hole 16 is connected to the limiting hole 15. Under the action of the spring 12, the slider 14 of the pull rod 11 slides into the limiting hole 15. Push the pull rod 11 inward, and the clamp 18 is engaged between the elastic clips 17. At this time, the side wall of the sliding sleeve 4 blocks the side of the mounting groove 8 to prevent the shaft head 2 from moving. The pull rod 11 fixes the sliding sleeve 4 and the rotating block 7. When it is necessary to disassemble the air shaft 1, first pull the pull rod 11 out of the limiting hole 15 to remove the limitation on the sliding sleeve 4. Then, the sliding sleeve 4 is moved to the right by the motor 6 until the opening on the side of the mounting groove 8 is exposed. The air shaft 1 is lifted with a special lifting tool, and the limiting protrusion 9 of the shaft head 2 is moved out of the limiting protrusion groove 10 through the opening on the side of the mounting groove 8. The air shaft 1 is then disassembled.

[0028] Therefore, this utility model adopts the above-mentioned detachable air shaft mounting assembly, which solves the problem that air shafts are generally fixed and cannot be disassembled, making it difficult to remove and replace them. It makes it easy to lock or loosen the air shaft, shortens the air shaft replacement time, and improves the air shaft replacement efficiency.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
